In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, as the MFS Total Return Bond Fund outpaced its respective benchmark.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, as the MFS Total Return Bond Fund outpaced its respective benchmark.

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.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, as the MFS Total Return Bond Fund outpaced its respective benchmark.

The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.<span style="white-space: nowrap;"> </span> 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.</div> </li> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, as the MFS Total Return Bond Fund outpaced its respective benchmark.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, as the MFS Total Return Bond Fund outpaced its respective benchmark.

The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.<span style="white-space: nowrap;"> </span> 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.</div> </li> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, as the MFS Total Return Bond Fund outpaced its respective benchmark.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, as the MFS Total Return Bond Fund outpaced its respective benchmark.

The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.<span style="white-space: nowrap;"> </span> 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.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, as the MFS Total Return Bond Fund outpaced its respective benchmark.

However, volatility later retracted as the risk of a broader regional military escalation appeared less likely.

This compares with a return of <span style="white-space: nowrap;">31.05%</span> for the fund’s benchmark, the Standard & Poor's 500 Stock Index. The fund's other benchmark, the MFS Lifetime 2030 Fund Blended Index (Blended Index), generated a return of <span style="white-space: nowrap;">14.05%</span>. 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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.<span style="white-space: nowrap;"> </span> 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.</div> </li> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The international equity segment also benefited the fund's relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

However, volatility later retracted as the risk of a broader regional military escalation appeared less likely.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The international equity segment also benefited the fund's relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

However, volatility later retracted as the risk of a broader regional military escalation appeared less likely.

The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.<span style="white-space: nowrap;"> </span> 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.</div> </li> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The international equity segment also benefited the fund's relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The international equity segment also benefited the fund's relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

However, volatility later retracted as the risk of a broader regional military escalation appeared less likely.

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.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The international equity segment also benefited the fund's relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.<span style="white-space: nowrap;"> </span> 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.</div> </li> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The international equity segment also benefited the fund's relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.

This compares with a return of <span style="white-space: nowrap;">31.05%</span> for the fund’s benchmark, the Standard & Poor's 500 Stock Index. The fund's other benchmark, the MFS Lifetime 2035 Fund Blended Index (Blended Index), generated a return of <span style="white-space: nowrap;">19.08%</span>. 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.

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.<span style="white-space: nowrap;"> </span> 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.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The international equity segment also benefited the fund's relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div><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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The international equity segment also benefited the fund's relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div><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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div><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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The international equity segment also benefited the fund's relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div><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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The international equity segment also benefited the fund's relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The international equity segment also benefited the fund's relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The international equity segment also benefited the fund's relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The international equity segment also benefited the fund's relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The international equity segment also benefited the fund's relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

However, volatility later retracted as the risk of a broader regional military escalation appeared less likely.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The international equity segment also benefited the fund's relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

However, volatility later retracted as the risk of a broader regional military escalation appeared less likely.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The international equity segment also benefited the fund's relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

However, volatility later retracted as the risk of a broader regional military escalation appeared less likely.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment also aided relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

However, volatility later retracted as the risk of a broader regional military escalation appeared less likely.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment also aided relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment also aided relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment also aided relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment also aided relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment also aided relative performance, led by allocations to emerging markets debt and high yield credit.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -3pt 0 3pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

Optimism over artificial intelligence remained high.</div> </li> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

However, volatility later retracted as the risk of a broader regional military escalation appeared less likely.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

However, volatility later retracted as the risk of a broader regional military escalation appeared less likely.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

The fund's other benchmark, the MFS Lifetime 2055 Fund Blended Index (Blended Index), generated a return of <span style="white-space: nowrap;">28.01%</span>. 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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.<span style="white-space: nowrap;"> </span> 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.</div> </li> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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’s tariff strategy, the administration began deploying other authorities to largely replace the ones that were ruled unconstitutional.</div> </li> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.</div> </li> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.<span style="white-space: nowrap;"> </span> 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.</div> </li> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.<span style="white-space: nowrap;"> </span> 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.</div> </li> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

However, volatility later retracted as the risk of a broader regional military escalation appeared less likely.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

The market indices and related percentage allocations used to compile the Blended Index are set forth in the Fund Performance.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.<span style="white-space: nowrap;"> </span> 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.</div> </li> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's international equity segment benefited relative performance, as the MFS Blended Research International Equity Fund outpaced its respective benchmark.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Within the US equity segment, lagging relative performance across the majority of the strategies weighed on relative results as the funds generally underperformed their respective benchmarks.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, as the MFS Total Return Bond Fund outpaced its respective benchmark.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, as the MFS Total Return Bond Fund outpaced its respective benchmark.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, as the MFS Total Return Bond Fund outpaced its respective benchmark.

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.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, as the MFS Total Return Bond Fund outpaced its respective benchmark.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, as the MFS Total Return Bond Fund outpaced its respective benchmark.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Blended Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's fixed income segment was a primary contributor to relative performance, as the MFS Total Return Bond Fund outpaced its respective benchmark.

However, volatility later retracted as the risk of a broader regional military escalation appeared less likely.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Bloomberg U.S. Aggregate Bond Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's underweight exposure to the treasury sector and out-of-benchmark exposure to the collateralized mortgage obligation (CMO) sector aided relative performance.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Yield curve positioning also benefited relative returns.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Bloomberg U.S. Aggregate Bond Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Security selection within the mortgage-backed security (MBS) sector and within AA-rated bonds held back the fund's relative performance.</div> </li> </ul> </li> </ul> </div> <div style="font-family: 'arial'; font-size: 11.52pt; font-weight: bold; color: rgb(126, 45, 64); margin: 0px 0px 3pt 0px;">FUND PERFORMANCE</div> <div style="font-family: 'arial'; font-size: 11pt; font-weight: normal; color: rgb(0, 0, 0); margin: 0px 0px 10pt 0px;"><b> <i>The fund’s past performance is not a good predictor of the fund’s future performance. </i> </b>The graph and table below do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Bloomberg U.S. Aggregate Bond Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's underweight exposure to the treasury sector and out-of-benchmark exposure to the collateralized mortgage obligation (CMO) sector aided relative performance.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Yield curve positioning also benefited relative returns.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Bloomberg U.S. Aggregate Bond Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Security selection within the mortgage-backed security (MBS) sector and within AA-rated bonds held back the fund's relative performance.</div> </li> </ul> </li> </ul> </div> <div style="font-family: 'arial'; font-size: 11.52pt; font-weight: bold; color: rgb(126, 45, 64); margin: 0px 0px 3pt 0px;">FUND PERFORMANCE</div> <div style="font-family: 'arial'; font-size: 11pt; font-weight: normal; color: rgb(0, 0, 0); margin: 0px 0px 10pt 0px;"><b> <i>The fund’s past performance is not a good predictor of the fund’s future performance. </i> </b>The graph and table below do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares.

In Japan, the election of a pro-growth prime minister sent stocks to new highs prior to the conflict in Iran.

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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Bloomberg U.S. Aggregate Bond Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's underweight exposure to the treasury sector and out-of-benchmark exposure to the collateralized mortgage obligation (CMO) sector aided relative performance.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Yield curve positioning also benefited relative returns.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Bloomberg U.S. Aggregate Bond Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Security selection within the mortgage-backed security (MBS) sector and within AA-rated bonds held back the fund's relative performance.</div> </li> </ul> </li> </ul> </div> <div style="font-family: 'arial'; font-size: 11.52pt; font-weight: bold; color: rgb(126, 45, 64); margin: 0px 0px 3pt 0px;">FUND PERFORMANCE</div><div style="font-family: 'arial'; font-size: 11pt; font-weight: normal; color: rgb(0, 0, 0); margin: 0px 0px 10pt 0px;"><b> <i>The fund’s past performance is not a good predictor of the fund’s future performance. </i> </b>The graph and table below do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares.

Optimism over artificial intelligence remained high.</div> </li> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.

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.</div> </li> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">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.</div> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top contributors to performance relative to the Bloomberg U.S. Aggregate Bond Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">The fund's underweight exposure to the treasury sector and out-of-benchmark exposure to the collateralized mortgage obligation (CMO) sector aided relative performance.</div> </li> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Yield curve positioning also benefited relative returns.</div> </li> </ul> </li> </ul> </div> <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);"> <ul style="break-inside: avoid; padding: 0; margin: -4pt 0 5pt 0;"> <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;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Top detractors from performance relative to the Bloomberg U.S. Aggregate Bond Index:</div> <ul style="break-inside: avoid; padding: 0; margin: 0;"> <li style="font-weight: 400; font-family: 'Arial'; color: rgb(0, 0, 0); list-style-type: circle; font-size: 10pt; line-height: 11pt; padding-right: 6pt; padding-left: 0; margin-left: 16pt;"> <div style="font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); font-size: 10pt; line-height: 11pt; margin: 0px;">Security selection within the mortgage-backed security (MBS) sector and within AA-rated bonds held back the fund's relative performance.</div> </li> </ul> </li> </ul> </div> <div style="font-family: 'arial'; font-size: 11.52pt; font-weight: bold; color: rgb(126, 45, 64); margin: 0px 0px 3pt 0px;">FUND PERFORMANCE</div><div style="font-family: 'arial'; font-size: 11pt; font-weight: normal; color: rgb(0, 0, 0); margin: 0px 0px 10pt 0px;"><b> <i>The fund’s past performance is not a good predictor of the fund’s future performance. </i> </b>The graph and table below do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares.
