&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class A shares of the MFS Aggressive Growth Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;17.67%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Aggressive Growth Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;27.63%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;

A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; font-size: 9pt; color: rgb(0, 0, 0); break-inside: avoid; margin-top: -2pt; margin-bottom: 0px; border: 1pt solid rgb(128, 128, 128);"&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class B shares of the MFS Aggressive Growth Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;16.79%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Aggressive Growth Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;27.63%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class C shares of the MFS Aggressive Growth Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;16.78%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Aggressive Growth Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;27.63%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class I shares of the MFS Aggressive Growth Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;17.94%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Aggressive Growth Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;27.63%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R1 shares of the MFS Aggressive Growth Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;16.77%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Aggressive Growth Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;27.63%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R2 shares of the MFS Aggressive Growth Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;17.35%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Aggressive Growth Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;27.63%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R3 shares of the MFS Aggressive Growth Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;17.62%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Aggressive Growth Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;27.63%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R4 shares of the MFS Aggressive Growth Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;17.94%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Aggressive Growth Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;27.63%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R6 shares of the MFS Aggressive Growth Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;18.03%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Aggressive Growth Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;27.63%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class A shares of the MFS Conservative Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;9.59%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;5.13%&lt;/span&gt; for the fund&#x2019;s benchmark, the Bloomberg U.S. Aggregate Bond Index. The fund's other benchmark, the MFS Conservative Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;14.03%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class B shares of the MFS Conservative Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;8.75%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;5.13%&lt;/span&gt; for the fund&#x2019;s benchmark, the Bloomberg U.S. Aggregate Bond Index. The fund's other benchmark, the MFS Conservative Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;14.03%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class C shares of the MFS Conservative Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;8.78%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;5.13%&lt;/span&gt; for the fund&#x2019;s benchmark, the Bloomberg U.S. Aggregate Bond Index. The fund's other benchmark, the MFS Conservative Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;14.03%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; font-size: 9pt; color: rgb(0, 0, 0); break-inside: avoid; margin-top: -2pt; margin-bottom: 0px; border: 1pt solid rgb(128, 128, 128);"&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class I shares of the MFS Conservative Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;9.86%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;5.13%&lt;/span&gt; for the fund&#x2019;s benchmark, the Bloomberg U.S. Aggregate Bond Index. The fund's other benchmark, the MFS Conservative Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;14.03%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R1 shares of the MFS Conservative Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;8.77%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;5.13%&lt;/span&gt; for the fund&#x2019;s benchmark, the Bloomberg U.S. Aggregate Bond Index. The fund's other benchmark, the MFS Conservative Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;14.03%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R2 shares of the MFS Conservative Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;9.32%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;5.13%&lt;/span&gt; for the fund&#x2019;s benchmark, the Bloomberg U.S. Aggregate Bond Index. The fund's other benchmark, the MFS Conservative Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;14.03%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R3 shares of the MFS Conservative Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;9.63%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;5.13%&lt;/span&gt; for the fund&#x2019;s benchmark, the Bloomberg U.S. Aggregate Bond Index. The fund's other benchmark, the MFS Conservative Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;14.03%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R4 shares of the MFS Conservative Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;9.86%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;5.13%&lt;/span&gt; for the fund&#x2019;s benchmark, the Bloomberg U.S. Aggregate Bond Index. The fund's other benchmark, the MFS Conservative Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;14.03%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R6 shares of the MFS Conservative Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;9.94%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;5.13%&lt;/span&gt; for the fund&#x2019;s benchmark, the Bloomberg U.S. Aggregate Bond Index. The fund's other benchmark, the MFS Conservative Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;14.03%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; font-size: 9pt; color: rgb(0, 0, 0); break-inside: avoid; margin-top: -2pt; margin-bottom: 0px; border: 1pt solid rgb(128, 128, 128);"&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class A shares of the MFS Growth Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;15.22%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Growth Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;23.16%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; font-size: 9pt; color: rgb(0, 0, 0); break-inside: avoid; margin-top: -1pt; border: 1pt solid rgb(128, 128, 128);"&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class B shares of the MFS Growth Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;14.34%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Growth Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;23.16%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class C shares of the MFS Growth Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;14.36%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Growth Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;23.16%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class I shares of the MFS Growth Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;15.49%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Growth Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;23.16%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R1 shares of the MFS Growth Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;14.36%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Growth Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;23.16%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R2 shares of the MFS Growth Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;14.95%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Growth Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;23.16%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Growth Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;23.16%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R4 shares of the MFS Growth Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;15.50%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Growth Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;23.16%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R6 shares of the MFS Growth Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;15.56%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Growth Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;23.16%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; font-size: 9pt; color: rgb(0, 0, 0); break-inside: avoid; margin-top: -2pt; margin-bottom: 0px; border: 1pt solid rgb(128, 128, 128);"&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class A shares of the MFS Moderate Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;12.43%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Moderate Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;18.60%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; font-size: 9pt; color: rgb(0, 0, 0); break-inside: avoid; margin-top: -1pt; border: 1pt solid rgb(128, 128, 128);"&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class B shares of the MFS Moderate Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;11.53%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Moderate Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;18.60%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class C shares of the MFS Moderate Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;11.58%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Moderate Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;18.60%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class I shares of the MFS Moderate Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;12.66%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Moderate Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;18.60%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R1 shares of the MFS Moderate Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;11.51%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Moderate Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;18.60%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R2 shares of the MFS Moderate Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;12.10%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Moderate Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;18.60%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;

A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;

While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R3 shares of the MFS Moderate Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;12.40%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Moderate Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;18.60%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R4 shares of the MFS Moderate Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;12.68%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Moderate Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;18.60%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R6 shares of the MFS Moderate Allocation Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;12.74%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.78%&lt;/span&gt; for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the MFS Moderate Allocation Fund Blended Index (Blended Index), generated a return of &lt;span style="white-space: nowrap;"&gt;18.60%&lt;/span&gt;. The Blended Index reflects the blended returns of broad asset class indices, with percentage allocations to each index designed to resemble the long term strategic allocations of the fund. The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class A shares of the MFS Blended Research Mid Cap Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;20.79%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell Midcap&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index, generated a return of &lt;span style="white-space: nowrap;"&gt;22.37%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class B shares of the MFS Blended Research Mid Cap Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;19.92%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell Midcap&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index, generated a return of &lt;span style="white-space: nowrap;"&gt;22.37%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class C shares of the MFS Blended Research Mid Cap Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;19.92%&lt;/span&gt;, at net asset value.

&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class I shares of the MFS Blended Research Mid Cap Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;21.12%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index.

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R1 shares of the MFS Blended Research Mid Cap Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;20.81%&lt;/span&gt;, at net asset value.

&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R2 shares of the MFS Blended Research Mid Cap Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;20.44%&lt;/span&gt;, at net asset value.

The fund's other benchmark, the Russell Midcap&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index, generated a return of &lt;span style="white-space: nowrap;"&gt;22.37%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R3 shares of the MFS Blended Research Mid Cap Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;20.86%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell Midcap&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index, generated a return of &lt;span style="white-space: nowrap;"&gt;22.37%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R4 shares of the MFS Blended Research Mid Cap Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;21.11%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell Midcap&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index, generated a return of &lt;span style="white-space: nowrap;"&gt;22.37%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R6 shares of the MFS Blended Research Mid Cap Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;21.19%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell Midcap&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index, generated a return of &lt;span style="white-space: nowrap;"&gt;22.37%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class A shares of the MFS Blended Research Small Cap Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;32.41%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 2000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index, generated a return of &lt;span style="white-space: nowrap;"&gt;43.08%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class B shares of the MFS Blended Research Small Cap Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;31.44%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 2000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index, generated a return of &lt;span style="white-space: nowrap;"&gt;43.08%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class C shares of the MFS Blended Research Small Cap Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;31.49%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 2000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index, generated a return of &lt;span style="white-space: nowrap;"&gt;43.08%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class I shares of the MFS Blended Research Small Cap Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;32.79%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 2000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index, generated a return of &lt;span style="white-space: nowrap;"&gt;43.08%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R1 shares of the MFS Blended Research Small Cap Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;31.49%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 2000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index, generated a return of &lt;span style="white-space: nowrap;"&gt;43.08%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R2 shares of the MFS Blended Research Small Cap Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;32.08%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 2000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index, generated a return of &lt;span style="white-space: nowrap;"&gt;43.08%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R4 shares of the MFS Blended Research Small Cap Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;32.81%&lt;/span&gt;, at net asset value.

&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R6 shares of the MFS Blended Research Small Cap Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;32.96%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 2000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index, generated a return of &lt;span style="white-space: nowrap;"&gt;43.08%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class A shares of the MFS Blended Research Value Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;26.71%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 1000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Value Index, generated a return of &lt;span style="white-space: nowrap;"&gt;28.55%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class B shares of the MFS Blended Research Value Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;25.72%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 1000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Value Index, generated a return of &lt;span style="white-space: nowrap;"&gt;28.55%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class C shares of the MFS Blended Research Value Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;25.70%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 1000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Value Index, generated a return of &lt;span style="white-space: nowrap;"&gt;28.55%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class I shares of the MFS Blended Research Value Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;26.99%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 1000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Value Index, generated a return of &lt;span style="white-space: nowrap;"&gt;28.55%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R1 shares of the MFS Blended Research Value Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;26.72%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 1000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Value Index, generated a return of &lt;span style="white-space: nowrap;"&gt;28.55%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R2 shares of the MFS Blended Research Value Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;26.36%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 1000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Value Index, generated a return of &lt;span style="white-space: nowrap;"&gt;28.55%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R3 shares of the MFS Blended Research Value Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;26.67%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 1000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Value Index, generated a return of &lt;span style="white-space: nowrap;"&gt;28.55%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R4 shares of the MFS Blended Research Value Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;27.00%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 1000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Value Index, generated a return of &lt;span style="white-space: nowrap;"&gt;28.55%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;

This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 1000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Growth Index, generated a return of &lt;span style="white-space: nowrap;"&gt;28.66%&lt;/span&gt;.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class B shares of the MFS Blended Research Growth Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;27.31%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 1000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Growth Index, generated a return of &lt;span style="white-space: nowrap;"&gt;28.66%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class C shares of the MFS Blended Research Growth Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;27.32%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 1000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Growth Index, generated a return of &lt;span style="white-space: nowrap;"&gt;28.66%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class I shares of the MFS Blended Research Growth Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;28.58%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 1000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Growth Index, generated a return of &lt;span style="white-space: nowrap;"&gt;28.66%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R1 shares of the MFS Blended Research Growth Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;27.32%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 1000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Growth Index, generated a return of &lt;span style="white-space: nowrap;"&gt;28.66%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R2 shares of the MFS Blended Research Growth Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;27.96%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 1000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Growth Index, generated a return of &lt;span style="white-space: nowrap;"&gt;28.66%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R3 shares of the MFS Blended Research Growth Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;28.29%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 1000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Growth Index, generated a return of &lt;span style="white-space: nowrap;"&gt;28.66%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R4 shares of the MFS Blended Research Growth Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;28.60%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 1000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Growth Index, generated a return of &lt;span style="white-space: nowrap;"&gt;28.66%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R6 shares of the MFS Blended Research Growth Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;28.70%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;29.45%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 1000&lt;sup style="font-size: smaller; vertical-align: super;"&gt;&#xae;&lt;/sup&gt; Growth Index, generated a return of &lt;span style="white-space: nowrap;"&gt;28.66%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class B shares of the MFS Emerging Markets Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;43.36&lt;/span&gt;%, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;54.31&lt;/span&gt;% for the fund&#x2019;s benchmark, the MSCI Emerging Markets Index (net div).&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class C shares of the MFS Emerging Markets Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;43.32&lt;/span&gt;%, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;54.31&lt;/span&gt;% for the fund&#x2019;s benchmark, the MSCI Emerging Markets Index (net div).&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

This compares with a return of &lt;span style="white-space: nowrap;"&gt;54.31&lt;/span&gt;% for the fund&#x2019;s benchmark, the MSCI Emerging Markets Index (net div).&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R2 shares of the MFS Emerging Markets Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;44.01&lt;/span&gt;%, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;54.31&lt;/span&gt;% for the fund&#x2019;s benchmark, the MSCI Emerging Markets Index (net div).&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R3 shares of the MFS Emerging Markets Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;44.39&lt;/span&gt;%, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;54.31&lt;/span&gt;% for the fund&#x2019;s benchmark, the MSCI Emerging Markets Index (net div).&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R6 shares of the MFS Emerging Markets Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;44.97&lt;/span&gt;%, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;54.31&lt;/span&gt;% for the fund&#x2019;s benchmark, the MSCI Emerging Markets Index (net div).&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class A shares of the MFS International Growth Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;11.57%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;32.77%&lt;/span&gt; for the fund&#x2019;s benchmark, the MSCI All Country World (ex-US) Index (net div). The fund's other benchmark, the MSCI All Country World (ex-US) Growth Index (net div), generated a return of &lt;span style="white-space: nowrap;"&gt;27.50%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; font-size: 9pt; color: rgb(0, 0, 0); break-inside: avoid; margin-top: -2pt; margin-bottom: 0px; border: 1pt solid rgb(128, 128, 128);"&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class B shares of the MFS International Growth Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;10.74%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;32.77%&lt;/span&gt; for the fund&#x2019;s benchmark, the MSCI All Country World (ex-US) Index (net div). The fund's other benchmark, the MSCI All Country World (ex-US) Growth Index (net div), generated a return of &lt;span style="white-space: nowrap;"&gt;27.50%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; font-size: 9pt; color: rgb(0, 0, 0); break-inside: avoid; margin-top: -2pt; margin-bottom: 0px; border: 1pt solid rgb(128, 128, 128);"&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class C shares of the MFS International Growth Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;10.73%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;32.77%&lt;/span&gt; for the fund&#x2019;s benchmark, the MSCI All Country World (ex-US) Index (net div). The fund's other benchmark, the MSCI All Country World (ex-US) Growth Index (net div), generated a return of &lt;span style="white-space: nowrap;"&gt;27.50%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; font-size: 9pt; color: rgb(0, 0, 0); break-inside: avoid; margin-top: -2pt; margin-bottom: 0px; border: 1pt solid rgb(128, 128, 128);"&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class I shares of the MFS International Growth Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;11.85%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;32.77%&lt;/span&gt; for the fund&#x2019;s benchmark, the MSCI All Country World (ex-US) Index (net div). The fund's other benchmark, the MSCI All Country World (ex-US) Growth Index (net div), generated a return of &lt;span style="white-space: nowrap;"&gt;27.50%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R2 shares of the MFS International Growth Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;11.32%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;32.77%&lt;/span&gt; for the fund&#x2019;s benchmark, the MSCI All Country World (ex-US) Index (net div). The fund's other benchmark, the MSCI All Country World (ex-US) Growth Index (net div), generated a return of &lt;span style="white-space: nowrap;"&gt;27.50%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R3 shares of the MFS International Growth Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;11.56%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;32.77%&lt;/span&gt; for the fund&#x2019;s benchmark, the MSCI All Country World (ex-US) Index (net div). The fund's other benchmark, the MSCI All Country World (ex-US) Growth Index (net div), generated a return of &lt;span style="white-space: nowrap;"&gt;27.50%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R4 shares of the MFS International Growth Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;11.87%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;32.77%&lt;/span&gt; for the fund&#x2019;s benchmark, the MSCI All Country World (ex-US) Index (net div). The fund's other benchmark, the MSCI All Country World (ex-US) Growth Index (net div), generated a return of &lt;span style="white-space: nowrap;"&gt;27.50%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R6 shares of the MFS International Growth Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;11.96%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;32.77%&lt;/span&gt; for the fund&#x2019;s benchmark, the MSCI All Country World (ex-US) Index (net div). The fund's other benchmark, the MSCI All Country World (ex-US) Growth Index (net div), generated a return of &lt;span style="white-space: nowrap;"&gt;27.50%&lt;/span&gt;.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R2 shares of the MFS International Intrinsic Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;21.14&lt;/span&gt;%, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;22.80&lt;/span&gt;% for the fund&#x2019;s benchmark, the MSCI EAFE (Europe, Australasia, Far East) Index (net div).&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R3 shares of the MFS International Intrinsic Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;21.43&lt;/span&gt;%, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;22.80&lt;/span&gt;% for the fund&#x2019;s benchmark, the MSCI EAFE (Europe, Australasia, Far East) Index (net div).&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

This compares with a return of &lt;span style="white-space: nowrap;"&gt;22.80&lt;/span&gt;% for the fund&#x2019;s benchmark, the MSCI EAFE (Europe, Australasia, Far East) Index (net div).&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R6 shares of the MFS International Intrinsic Equity Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;21.88&lt;/span&gt;%, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;22.80&lt;/span&gt;% for the fund&#x2019;s benchmark, the MSCI EAFE (Europe, Australasia, Far East) Index (net div).&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;An overweight allocation and security selection within the energy sector also benefited relative performance.

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class B shares of the MFS International Diversification Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;21.53&lt;/span&gt;%, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;32.77&lt;/span&gt;% for the fund&#x2019;s benchmark, the MSCI All Country World (ex-US) Index (net div).&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class I shares of the MFS International Diversification Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;22.76&lt;/span&gt;%, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;32.77&lt;/span&gt;% for the fund&#x2019;s benchmark, the MSCI All Country World (ex-US) Index (net div).&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;

Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;

This compares with a return of &lt;span style="white-space: nowrap;"&gt;32.77&lt;/span&gt;% for the fund&#x2019;s benchmark, the MSCI All Country World (ex-US) Index (net div).&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R3 shares of the MFS International Diversification Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;22.43&lt;/span&gt;%, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;32.77&lt;/span&gt;% for the fund&#x2019;s benchmark, the MSCI All Country World (ex-US) Index (net div).&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

This compares with a return of &lt;span style="white-space: nowrap;"&gt;32.77&lt;/span&gt;% for the fund&#x2019;s benchmark, the MSCI All Country World (ex-US) Index (net div).&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;The MFS Managed Wealth Fund's (fund) investment objective is to seek total return. MFS seeks to achieve the fund&#x2019;s objective by generating returns from (1) a strategic allocation to three MFS equity funds, referred to as underlying funds, and (2) a tactical asset allocation overlay primarily using derivative instruments to seek to decrease the volatility of the fund&#x2019;s returns by reducing the fund&#x2019;s exposure to the equity and/or currency markets as represented by the underlying funds and also to potentially expose the fund to asset classes and/or markets in which the underlying funds have little or no exposure. In addition, MFS may seek to limit the fund&#x2019;s exposure to certain extreme market events. It is expected that the fund will generally have lower volatility than the overall equity market and will generally underperform the equity markets during periods of rising equity markets.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class A shares of the fund provided a total return of 4.03%, at net asset value. This compares with a return of 29.78% for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the ICE BofA 0-3 Month U.S. Treasury Bill Index, generated a return of 3.99%.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;The MFS Managed Wealth Fund's (fund) investment objective is to seek total return. MFS seeks to achieve the fund&#x2019;s objective by generating returns from (1) a strategic allocation to three MFS equity funds, referred to as underlying funds, and (2) a tactical asset allocation overlay primarily using derivative instruments to seek to decrease the volatility of the fund&#x2019;s returns by reducing the fund&#x2019;s exposure to the equity and/or currency markets as represented by the underlying funds and also to potentially expose the fund to asset classes and/or markets in which the underlying funds have little or no exposure. In addition, MFS may seek to limit the fund&#x2019;s exposure to certain extreme market events. It is expected that the fund will generally have lower volatility than the overall equity market and will generally underperform the equity markets during periods of rising equity markets.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class B shares of the fund provided a total return of 3.23%, at net asset value. This compares with a return of 29.78% for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the ICE BofA 0-3 Month U.S. Treasury Bill Index, generated a return of 3.99%.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;The MFS Managed Wealth Fund's (fund) investment objective is to seek total return. MFS seeks to achieve the fund&#x2019;s objective by generating returns from (1) a strategic allocation to three MFS equity funds, referred to as underlying funds, and (2) a tactical asset allocation overlay primarily using derivative instruments to seek to decrease the volatility of the fund&#x2019;s returns by reducing the fund&#x2019;s exposure to the equity and/or currency markets as represented by the underlying funds and also to potentially expose the fund to asset classes and/or markets in which the underlying funds have little or no exposure. In addition, MFS may seek to limit the fund&#x2019;s exposure to certain extreme market events. It is expected that the fund will generally have lower volatility than the overall equity market and will generally underperform the equity markets during periods of rising equity markets.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class C shares of the fund provided a total return of 3.16%, at net asset value. This compares with a return of 29.78% for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the ICE BofA 0-3 Month U.S. Treasury Bill Index, generated a return of 3.99%.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-family: 'arial'; font-weight: normal; color: rgb(0, 0, 0); font-size: 8pt; margin: 0px 0px 6pt 0px;"&gt;(a) Represents the actively managed portion of the portfolio and for purposes of this presentation, components include the value of securities, less any securities sold short. The bond component will include any accrued interest amounts. This also reflects the equivalent exposure of certain derivative positions. These amounts may be negative from time to time.&lt;/div&gt;

&lt;div style="font-family: 'arial'; font-weight: normal; color: rgb(0, 0, 0); font-size: 8pt; margin: 0px 0px 6pt 0px;"&gt;(b) Represents the tactical overlay portion of the portfolio which is how the fund manages its exposure to markets and currencies through the use of derivative positions. Percentages reflect the equivalent exposure of those derivative positions.&lt;/div&gt;

&lt;div style="font-family: 'arial'; font-weight: normal; color: rgb(0, 0, 0); font-size: 8pt; margin: 0px 0px 6pt 0px;"&gt;(c) For purposes of this presentation, the components include the value of securities, less any securities sold short, and reflect the impact of the equivalent exposure of all derivative positions. These amounts may be negative from time to time. The bond component will include any accrued interest amounts.&lt;/div&gt;

&lt;div style="font-family: 'arial'; font-weight: normal; color: rgb(0, 0, 0); font-size: 8pt; margin: 0px 0px 6pt 0px;"&gt;(d) Cash &amp;amp; Cash Equivalents includes any cash, investments in money market funds, short-term securities, and other assets less liabilities.&lt;/div&gt;

&lt;div style="font-family: 'arial'; font-weight: normal; color: rgb(0, 0, 0); font-size: 8pt; margin: 0px 0px 6pt 0px;"&gt;Portfolio Composition presents the value of securities, including equivalent exposure of derivative positions. Equivalent exposure is a reasonable approximation of the amount of the underlying asset the portfolio would have to hold to have the same price sensitivity of the derivative contract. Bonds include any accrued interest amounts.&lt;/div&gt;

&lt;div style="font-family: 'arial'; font-weight: normal; color: rgb(0, 0, 0); font-size: 8pt; margin: 0px 0px 6pt 0px;"&gt;Where the fund holds convertible bonds, they are treated as part of the equity portion of the portfolio.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;The MFS Managed Wealth Fund's (fund) investment objective is to seek total return. MFS seeks to achieve the fund&#x2019;s objective by generating returns from (1) a strategic allocation to three MFS equity funds, referred to as underlying funds, and (2) a tactical asset allocation overlay primarily using derivative instruments to seek to decrease the volatility of the fund&#x2019;s returns by reducing the fund&#x2019;s exposure to the equity and/or currency markets as represented by the underlying funds and also to potentially expose the fund to asset classes and/or markets in which the underlying funds have little or no exposure. In addition, MFS may seek to limit the fund&#x2019;s exposure to certain extreme market events. It is expected that the fund will generally have lower volatility than the overall equity market and will generally underperform the equity markets during periods of rising equity markets.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class I shares of the fund provided a total return of 4.31%, at net asset value. This compares with a return of 29.78% for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the ICE BofA 0-3 Month U.S. Treasury Bill Index, generated a return of 3.99%.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

The bond component will include any accrued interest amounts. This also reflects the equivalent exposure of certain derivative positions. These amounts may be negative from time to time.&lt;/div&gt;



&lt;div style="font-family: 'arial'; font-weight: normal; color: rgb(0, 0, 0); font-size: 8pt; margin: 0px 0px 6pt 0px;"&gt;(b) Represents the tactical overlay portion of the portfolio which is how the fund manages its exposure to markets and currencies through the use of derivative positions. Percentages reflect the equivalent exposure of those derivative positions.&lt;/div&gt;



&lt;div style="font-family: 'arial'; font-weight: normal; color: rgb(0, 0, 0); font-size: 8pt; margin: 0px 0px 6pt 0px;"&gt;(c) For purposes of this presentation, the components include the value of securities, less any securities sold short, and reflect the impact of the equivalent exposure of all derivative positions. These amounts may be negative from time to time. The bond component will include any accrued interest amounts.&lt;/div&gt;

&lt;div style="font-family: 'arial'; font-weight: normal; color: rgb(0, 0, 0); font-size: 8pt; margin: 0px 0px 6pt 0px;"&gt;Where the fund holds convertible bonds, they are treated as part of the equity portion of the portfolio.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;The MFS Managed Wealth Fund's (fund) investment objective is to seek total return. MFS seeks to achieve the fund&#x2019;s objective by generating returns from (1) a strategic allocation to three MFS equity funds, referred to as underlying funds, and (2) a tactical asset allocation overlay primarily using derivative instruments to seek to decrease the volatility of the fund&#x2019;s returns by reducing the fund&#x2019;s exposure to the equity and/or currency markets as represented by the underlying funds and also to potentially expose the fund to asset classes and/or markets in which the underlying funds have little or no exposure. In addition, MFS may seek to limit the fund&#x2019;s exposure to certain extreme market events. It is expected that the fund will generally have lower volatility than the overall equity market and will generally underperform the equity markets during periods of rising equity markets.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R1 shares of the fund provided a total return of 3.23%, at net asset value. This compares with a return of 29.78% for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the ICE BofA 0-3 Month U.S. Treasury Bill Index, generated a return of 3.99%.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;The MFS Managed Wealth Fund's (fund) investment objective is to seek total return. MFS seeks to achieve the fund&#x2019;s objective by generating returns from (1) a strategic allocation to three MFS equity funds, referred to as underlying funds, and (2) a tactical asset allocation overlay primarily using derivative instruments to seek to decrease the volatility of the fund&#x2019;s returns by reducing the fund&#x2019;s exposure to the equity and/or currency markets as represented by the underlying funds and also to potentially expose the fund to asset classes and/or markets in which the underlying funds have little or no exposure. In addition, MFS may seek to limit the fund&#x2019;s exposure to certain extreme market events. It is expected that the fund will generally have lower volatility than the overall equity market and will generally underperform the equity markets during periods of rising equity markets.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R2 shares of the fund provided a total return of 3.73%, at net asset value. This compares with a return of 29.78% for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the ICE BofA 0-3 Month U.S. Treasury Bill Index, generated a return of 3.99%.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;The MFS Managed Wealth Fund's (fund) investment objective is to seek total return. MFS seeks to achieve the fund&#x2019;s objective by generating returns from (1) a strategic allocation to three MFS equity funds, referred to as underlying funds, and (2) a tactical asset allocation overlay primarily using derivative instruments to seek to decrease the volatility of the fund&#x2019;s returns by reducing the fund&#x2019;s exposure to the equity and/or currency markets as represented by the underlying funds and also to potentially expose the fund to asset classes and/or markets in which the underlying funds have little or no exposure. In addition, MFS may seek to limit the fund&#x2019;s exposure to certain extreme market events. It is expected that the fund will generally have lower volatility than the overall equity market and will generally underperform the equity markets during periods of rising equity markets.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R3 shares of the fund provided a total return of 3.93%, at net asset value. This compares with a return of 29.78% for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the ICE BofA 0-3 Month U.S. Treasury Bill Index, generated a return of 3.99%.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;The MFS Managed Wealth Fund's (fund) investment objective is to seek total return. MFS seeks to achieve the fund&#x2019;s objective by generating returns from (1) a strategic allocation to three MFS equity funds, referred to as underlying funds, and (2) a tactical asset allocation overlay primarily using derivative instruments to seek to decrease the volatility of the fund&#x2019;s returns by reducing the fund&#x2019;s exposure to the equity and/or currency markets as represented by the underlying funds and also to potentially expose the fund to asset classes and/or markets in which the underlying funds have little or no exposure. In addition, MFS may seek to limit the fund&#x2019;s exposure to certain extreme market events. It is expected that the fund will generally have lower volatility than the overall equity market and will generally underperform the equity markets during periods of rising equity markets.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R4 shares of the fund provided a total return of 4.31%, at net asset value. This compares with a return of 29.78% for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the ICE BofA 0-3 Month U.S. Treasury Bill Index, generated a return of 3.99%.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;

The bond component will include any accrued interest amounts. This also reflects the equivalent exposure of certain derivative positions. These amounts may be negative from time to time.&lt;/div&gt;

Percentages reflect the equivalent exposure of those derivative positions.&lt;/div&gt;



&lt;div style="font-family: 'arial'; font-weight: normal; color: rgb(0, 0, 0); font-size: 8pt; margin: 0px 0px 6pt 0px;"&gt;(c) For purposes of this presentation, the components include the value of securities, less any securities sold short, and reflect the impact of the equivalent exposure of all derivative positions. These amounts may be negative from time to time. The bond component will include any accrued interest amounts.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;The MFS Managed Wealth Fund's (fund) investment objective is to seek total return. MFS seeks to achieve the fund&#x2019;s objective by generating returns from (1) a strategic allocation to three MFS equity funds, referred to as underlying funds, and (2) a tactical asset allocation overlay primarily using derivative instruments to seek to decrease the volatility of the fund&#x2019;s returns by reducing the fund&#x2019;s exposure to the equity and/or currency markets as represented by the underlying funds and also to potentially expose the fund to asset classes and/or markets in which the underlying funds have little or no exposure. In addition, MFS may seek to limit the fund&#x2019;s exposure to certain extreme market events. It is expected that the fund will generally have lower volatility than the overall equity market and will generally underperform the equity markets during periods of rising equity markets.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R6 shares of the fund provided a total return of 4.30%, at net asset value. This compares with a return of 29.78% for the fund&#x2019;s benchmark, the Standard &amp;amp; Poor's 500 Stock Index. The fund's other benchmark, the ICE BofA 0-3 Month U.S. Treasury Bill Index, generated a return of 3.99%.&lt;/div&gt;

A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class A shares of the MFS International Large Cap Value Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;28.26%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;22.80%&lt;/span&gt; for the fund&#x2019;s benchmark, the MSCI EAFE (Europe, Australasia, Far East) Index (net div). The fund's other benchmark, the MSCI EAFE (Europe, Australasia, Far East) Value Index (net div), generated a return of &lt;span style="white-space: nowrap;"&gt;30.07%&lt;/span&gt;.&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class C shares of the MFS International Large Cap Value Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;27.22%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;22.80%&lt;/span&gt; for the fund&#x2019;s benchmark, the MSCI EAFE (Europe, Australasia, Far East) Index (net div). The fund's other benchmark, the MSCI EAFE (Europe, Australasia, Far East) Value Index (net div), generated a return of &lt;span style="white-space: nowrap;"&gt;30.07%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class I shares of the MFS International Large Cap Value Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;28.57%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;22.80%&lt;/span&gt; for the fund&#x2019;s benchmark, the MSCI EAFE (Europe, Australasia, Far East) Index (net div). The fund's other benchmark, the MSCI EAFE (Europe, Australasia, Far East) Value Index (net div), generated a return of &lt;span style="white-space: nowrap;"&gt;30.07%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R1 shares of the MFS International Large Cap Value Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;27.27%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;22.80%&lt;/span&gt; for the fund&#x2019;s benchmark, the MSCI EAFE (Europe, Australasia, Far East) Index (net div). The fund's other benchmark, the MSCI EAFE (Europe, Australasia, Far East) Value Index (net div), generated a return of &lt;span style="white-space: nowrap;"&gt;30.07%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R2 shares of the MFS International Large Cap Value Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;27.90%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;22.80%&lt;/span&gt; for the fund&#x2019;s benchmark, the MSCI EAFE (Europe, Australasia, Far East) Index (net div). The fund's other benchmark, the MSCI EAFE (Europe, Australasia, Far East) Value Index (net div), generated a return of &lt;span style="white-space: nowrap;"&gt;30.07%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;For the twelve months ended May 31, 2026, Class R4 shares of the MFS International Large Cap Value Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;28.58%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;22.80%&lt;/span&gt; for the fund&#x2019;s benchmark, the MSCI EAFE (Europe, Australasia, Far East) Index (net div). The fund's other benchmark, the MSCI EAFE (Europe, Australasia, Far East) Value Index (net div), generated a return of &lt;span style="white-space: nowrap;"&gt;30.07%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. A new geopolitical event distressed markets at the end of the period as US and Israeli forces launched strikes against Iran, disrupting Mideast oil and natural gas exports. &lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;During the period, a pro-growth tax and spending bill was signed into law in the US, while in Europe, renewed focus on defense and infrastructure spending brightened the economic outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran. Optimism over artificial intelligence remained high.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;

While the US Supreme Court struck down part of the Trump administration&#x2019;s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;Early in the period, moderating inflation pressures allowed many global central banks to ease monetary policy. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September and delivered quarter-point rate cuts in October and December before pausing.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="font-weight: 400; padding-left: 2pt; margin-top: 6pt; margin-left: 16pt; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: disc; font-size: 10pt; line-height: 11pt; padding-right: 6pt;"&gt;
&lt;div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;"&gt;In fixed income markets, previously range-bound global bond yields spiked following the onset of the Middle East conflict, as energy-driven inflation fears appeared to have rattled bond investors. US rate volatility (as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index) similarly rose from intra-period lows, reflecting uncertainty around the scope and duration of the conflict and its implications for global growth. However, volatility later retracted as the risk of a broader regional military escalation appeared less likely. Global credit spreads widened only modestly before stabilizing near prior levels, supported by strong demand and resilient underlying fundamentals.&lt;/div&gt;
&lt;/li&gt;
