&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, security selection was the primary detractor from the fund's performance versus the benchmark Russell 2000 Index for the fiscal year, especially within industrials. Also hurting were our stock picks in financials, primarily within the insurance industry, and health care, primarily within the pharmaceuticals, biotechnology &amp;amp; life sciences industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The biggest individual relative detractor was an overweight in CBIZ (-55%). This period we increased our position in the stock, which was among the fund's biggest holdings. A second notable relative detractor was an overweight in Baldwin Insurance (-45%). The company was among the fund's largest holdings for the 12 months. Another notable relative detractor was avoiding Bloom Energy, a benchmark component that gained roughly 1447%.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest contributor to performance versus the benchmark was stock selection in consumer discretionary. Stock selection and an underweight in information technology, primarily within the technology hardware &amp;amp; equipment industry, also boosted the fund's relative result. Also bolstering relative performance was an overweight in industrials.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in IES Holdings (+221%), which was among the fund's top holdings. The second-largest relative contributor was an overweight in Sanmina (+182%). This period we increased our position in Sanmina, making it the biggest holding at period end. An overweight in Perimeter Solutions (+206%) also contributed. This period we increased our position in Perimeter Solutions. It was among our largest holdings.&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align:left;text-align-last:auto;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:11px;color:#000000;font-style:normal;font-weight:bold;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, security selection was the primary detractor from the fund's performance versus the benchmark Russell 2000 Index for the fiscal year, especially within industrials. Also hurting our result was security selection in financials, primarily within the insurance industry, and health care, primarily within the pharmaceuticals, biotechnology &amp;amp; life sciences industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The largest individual relative detractor was an overweight in CBIZ (-55%). This period we increased our stake in CBIZ, which was among the fund's biggest holdings. A second notable relative detractor was an overweight in Baldwin Insurance (-45%). The company was among the fund's largest holdings for the 12 months. Not owning Bloom Energy, a benchmark component that gained approximately 1447%, was another notable relative detractor.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest contributor to performance versus the benchmark was stock selection in consumer discretionary. Security selection and an underweight in information technology, primarily within the technology hardware &amp;amp; equipment industry, also boosted the fund's relative result. Also helping relative performance was an overweight in industrials.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in IES Holdings (+220%). This period we decreased our investment in the stock, which was among our largest holdings. The second-biggest relative contributor was an overweight in Sanmina (+184%). The company was one of the fund's largest holdings at period end. Another notable relative contributor was an overweight in Perimeter Solutions (+203%).

&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, security selection was the primary detractor from the fund's performance versus the Russell 2000 Index for the fiscal year, especially within the industrials sector. Picks in health care, primarily the pharmaceuticals, biotechnology &amp;amp; life sciences industry, also hampered the fund's result. Further detracting from our result were investment choices and an underweight in materials.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The biggest individual relative detractor was our non-benchmark stake in Genpact (-30%), where we decreased our investment this period. Still, the company was among the fund's biggest holdings. A non-benchmark stake in Kyndryl Holdings returned -66% and was another notable relative detractor. The stock was not held at period end. An overweight in Insight Enterprises (-47%) also hurt. The company was among the fund's largest holdings this period.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest contributor to performance versus the benchmark was security selection in consumer discretionary, primarily within the consumer services industry. An overweight in industrials and an underweight in real estate, primarily within the equity real estate investment trusts industry, also boosted the fund's relative performance.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in IES Holdings (+229%), one of our largest holdings. A second notable relative contributor was an overweight in Sanmina (+184%), another of the fund's biggest holding at period end. An overweight in Fabrinet (+231%) also helped. The stock was among the fund's biggest holdings.&lt;/span&gt;&lt;/div&gt;

Stock picks in health care, primarily the pharmaceuticals, biotechnology &amp;amp; life sciences industry, also hampered the fund's result. Further detracting from our result were investment choices and an underweight in materials.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The fund's non-benchmark stake in Genpact returned about -30% and was the largest individual relative detractor. We decreased our position in Genpact, though the company was the fund's biggest holding this period. A non-benchmark stake in Kyndryl Holdings returned -66% and was a second notable relative detractor. The stock was not held at period end. Another notable relative detractor was an overweight in Insight Enterprises (-47%), one of our largest holdings this period.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest contributor to performance versus the benchmark was stock selection in consumer discretionary. An overweight in industrials and an underweight in real estate, primarily within the equity real estate investment trusts industry, also boosted the fund's relative performance.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in IES Holdings (+229%), one of the fund's largest holdings. A second notable relative contributor was an overweight in Sanmina (+184%), the fund's biggest holding at period end. An overweight in Fabrinet (+235%) also helped. The stock was one of our largest holdings.&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, security selection was the primary contributor to the fund's performance versus the Russell 2000 Index for the fiscal year, led by information technology, where our stock picks in technology hardware &amp;amp; equipment helped most. Stock selection in financials, primarily within the banks industry, and health care, primarily within the pharmaceuticals, biotechnology &amp;amp; life sciences industry, also boosted the fund's relative performance.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was our non-benchmark stake in Lumentum Holdings (+813%). The stock was not held at period end. The second-largest relative contributor was an overweight in IES Holdings (+225%). The company was the fund's biggest holding at period end. Another notable relative contributor was an overweight in Solaris Energy Infrastructure (+214%). This was a stake we established this period. The company was among the fund's largest holdings at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest detractors from performance versus the benchmark were picks and an underweight in materials. Stock selection in industrials, primarily within the commercial &amp;amp; professional services industry, also hampered the fund's result. Also detracting from our result were stock picks and an underweight in energy. Lastly, the fund's position in cash detracted.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The biggest individual relative detractor was an underweight in Bloom Energy (+1447%). This was a stake we established this period. The company was one of the fund's largest holdings at period end. A second notable relative detractor was an overweight in PAR Technology (-77%). An underweight in Credo Technology (+304%) also detracted. This was a stake we established this period.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Notable changes in positioning include increased exposure to the materials and information technology sectors.&lt;/span&gt;&lt;/div&gt;

Stock selection in industrials, within the capital goods industry, also boosted relative performance. Also lifting the fund's relative result was an overweight in energy.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in Ciena (+641%). This period we decreased our stake in Ciena. The company was one of the fund's biggest holdings this period. A non-benchmark stake in Western Digital gained roughly 895% and was a second notable relative contributor. This was a stake we established this period. Another notable relative contributor was an overweight in Lumentum Holdings (+1377%). This period we decreased our stake in Lumentum Holdings.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest detractors from performance versus the benchmark were picks and an overweight in consumer discretionary. Security selection in communication services, primarily within the media &amp;amp; entertainment industry, also hampered the fund's result. Also detracting from our result was an underweight in information technology, primarily within the semiconductors &amp;amp; semiconductor equipment industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The largest individual relative detractor was our non-benchmark stake in Brunello Cucinelli (-13%). Not owning MasTec, a benchmark component that gained about 210%, was the second-largest relative detractor. A non-benchmark stake in Molina Healthcare returned -54% and notably hurt. The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Notable changes in positioning include decreased exposure to the consumer staples sector and a higher allocation to information technology.&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, security selection was the primary contributor to the fund's performance versus the S&amp;amp;P MidCap 400 Index for the fiscal year, led by information technology. Stock picks in industrials, within the capital goods industry, also boosted relative performance. Also helping our relative result was an overweight in energy.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in Ciena (+638%). This period we considerably decreased our share count in Ciena. The company was one of the fund's biggest holdings this period. A non-benchmark stake in Western Digital gained 894% and was a second notable relative contributor. This was an investment we established this period. Another notable relative contributor was an overweight in Lumentum Holdings (+1374%). This period we decreased our stake in Lumentum Holdings.&#160;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, picks and an overweight in consumer discretionary detracted most from performance versus the benchmark. An underweight in information technology, primarily within the semiconductors &amp;amp; semiconductor equipment industry, also hampered the fund's result. Also hurting our result was stock selection in communication services, primarily within the media &amp;amp; entertainment industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The largest individual relative detractor was our non-benchmark stake in Brunello Cucinelli (-13%). A second notable relative detractor this period was avoiding MasTec, a benchmark component that gained roughly 210%. Another notable relative detractor was our non-benchmark stake in Molina Healthcare (-54%). The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Notable changes in positioning include decreased exposure to the consumer staples sector and a higher allocation to information technology.&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, security selection was the primary contributor to the fund's performance versus the S&amp;amp;P MidCap 400 Index for the fiscal year, led by information technology. Stock picks in industrials, within the capital goods industry, also boosted relative performance. Also helping our relative result was an overweight in energy.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in Ciena (+638%). This period we considerably decreased our share count in Ciena. The company was one of the fund's biggest holdings this period. A non-benchmark stake in Western Digital gained 894% and was a second notable relative contributor. This was an investment we established this period. Another notable relative contributor was an overweight in Lumentum Holdings (+1374%). This period we decreased our stake in Lumentum Holdings.&#160;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, picks and an overweight in consumer discretionary detracted most from performance versus the benchmark. An underweight in information technology, primarily within the semiconductors &amp;amp; semiconductor equipment industry, also hampered the fund's result. Also hurting our result was stock selection in communication services, primarily within the media &amp;amp; entertainment industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The largest individual relative detractor was our non-benchmark stake in Brunello Cucinelli (-13%). A second notable relative detractor this period was avoiding MasTec, a benchmark component that gained roughly 210%. Another notable relative detractor was our non-benchmark stake in Molina Healthcare (-54%). The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, security selection was the primary contributor to the fund's performance versus the benchmark S&amp;amp;P 500 index for the fiscal year, led by industrials. Stock picking in financials and information technology also boosted the fund's relative result.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in GE Vernova (+191%), which was among the fund's largest holdings. A second notable relative contributor was an overweight in GE Aerospace (+45%), also one of the fund's biggest holdings. Another notable relative contributor this period was avoiding Berkshire Hathaway, a benchmark component that returned -11%.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest detractor from performance versus the benchmark was an underweight in information technology. Also hurting our result was security selection in real estate and consumer staples, primarily within the food, beverage &amp;amp; tobacco industry. Lastly, the fund's position in cash detracted.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Not owning Advanced Micro Devices, a benchmark component that gained 264%, was the largest individual relative detractor. A non-benchmark stake in SAP returned about -42% and was a second notable relative detractor. An overweight in Boston Scientific (-44%) also hurt. This period we increased our investment in Boston Scientific.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Notable changes in positioning include increased exposure to the consumer discretionary sector and a lower allocation to financials.&lt;/span&gt;&lt;/div&gt;

Stock picking in financials and information technology also boosted the fund's relative result.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in GE Vernova (+193%). The company was among our biggest holdings. The second-largest relative contributor was an overweight in GE Aerospace (+45%). The stock was among our top holdings. Another notable relative contributor was a non-benchmark stake in Imperial Oil (+103%).&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest detractor from performance versus the benchmark was an underweight in information technology. An overweight in financials also hampered the fund's result. Also hurting our result were picks in real estate. Lastly, the fund's position in cash detracted.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Not owning Advanced Micro Devices, a benchmark component that gained 264%, was the biggest individual relative detractor. A non-benchmark stake in SAP returned roughly -42% and was a second notable relative detractor. An overweight in Boston Scientific (-44%) also hurt.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Notable changes in positioning include increased exposure to the consumer discretionary sector and a lower allocation to financials.&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, security selection was the primary detractor from the fund's performance versus the Russell 3000&#xae; Index for the fiscal year, especially within industrials. Security selection in communication services, primarily within the media &amp;amp; entertainment industry, also hampered the fund's result. Also hurting our result were stock picks and an overweight in financials.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The biggest individual relative detractor this period was avoiding Broadcom, a benchmark component that gained approximately 119%. Not owning Micron Technology, a benchmark component that gained about 574%, was a second notable relative detractor. Another notable relative detractor was our stake in ROBLOX (+3%). The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;

Stock picks and an underweight in consumer staples and stock picking and an overweight in materials also boosted the fund's relative performance.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in Alphabet (+137%). The company was the fund's largest holding at period end. A second notable relative contributor was our stake in Oracle (+48%). The stock was not held at period end. An overweight in Coca-Cola Consolidated (+53%) also helped. This period we increased our investment in Coca-Cola Consolidated. The company was one of our biggest holdings at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Notable changes in positioning include higher allocations to the consumer staples and materials sectors.&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, security selection was the primary detractor from the fund's performance versus the Russell 3000&#xae; Index for the fiscal year, especially within industrials. Security selection in communication services, primarily within the media &amp;amp; entertainment industry, also hampered the fund's result. Also hurting our result were stock picks and an overweight in financials.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The biggest individual relative detractor this period was avoiding Broadcom, a benchmark component that gained approximately 119%. Not owning Micron Technology, a benchmark component that gained about 574%, was a second notable relative detractor. Another notable relative detractor was our stake in ROBLOX (+3%). The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest contributor to performance versus the benchmark was stock picking in consumer discretionary. Stock picks and an underweight in consumer staples and stock picking and an overweight in materials also boosted the fund's relative performance.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in Alphabet (+137%). The company was the fund's largest holding at period end. A second notable relative contributor was our stake in Oracle (+48%). The stock was not held at period end. An overweight in Coca-Cola Consolidated (+53%) also helped. This period we increased our investment in Coca-Cola Consolidated. The company was one of our biggest holdings at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Notable changes in positioning include higher allocations to the consumer staples and materials sectors.&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, security selection was the primary detractor from the fund's performance versus the Russell 3000&#xae; Index for the fiscal year, especially within industrials. Security selection in communication services, primarily within the media &amp;amp; entertainment industry, also hampered the fund's result. Also hurting our result were stock picks and an overweight in financials.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The biggest individual relative detractor this period was avoiding Broadcom, a benchmark component that gained approximately 119%. Not owning Micron Technology, a benchmark component that gained about 574%, was a second notable relative detractor. Another notable relative detractor was our stake in ROBLOX (+3%). The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest contributor to performance versus the benchmark was stock picking in consumer discretionary. Stock picks and an underweight in consumer staples and stock picking and an overweight in materials also boosted the fund's relative performance.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in Alphabet (+137%). The company was the fund's largest holding at period end. A second notable relative contributor was our stake in Oracle (+48%). The stock was not held at period end. An overweight in Coca-Cola Consolidated (+53%) also helped. This period we increased our investment in Coca-Cola Consolidated. The company was one of our biggest holdings at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Notable changes in positioning include higher allocations to the consumer staples and materials sectors.&lt;/span&gt;&lt;/div&gt;

Security selection in communication services, primarily within the media &amp;amp; entertainment industry, also hampered the fund's result. Also hurting our result were stock picks and an overweight in financials.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The biggest individual relative detractor this period was avoiding Broadcom, a benchmark component that gained approximately 119%. Not owning Micron Technology, a benchmark component that gained about 574%, was a second notable relative detractor. Another notable relative detractor was our stake in ROBLOX (+3%). The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest contributor to performance versus the benchmark was stock picking in consumer discretionary. Stock picks and an underweight in consumer staples and stock picking and an overweight in materials also boosted the fund's relative performance.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in Alphabet (+137%). The company was the fund's largest holding at period end. A second notable relative contributor was our stake in Oracle (+48%). The stock was not held at period end. An overweight in Coca-Cola Consolidated (+53%) also helped. This period we increased our investment in Coca-Cola Consolidated. The company was one of our biggest holdings at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Notable changes in positioning include higher allocations to the consumer staples and materials sectors.&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, security selection was the primary detractor from the fund's performance versus the Russell 3000&#xae; Index for the fiscal year, especially within industrials. Security selection in communication services, primarily within the media &amp;amp; entertainment industry, also hampered the fund's result. Also hurting our result were stock picks and an overweight in financials.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The biggest individual relative detractor this period was avoiding Broadcom, a benchmark component that gained approximately 119%. Not owning Micron Technology, a benchmark component that gained about 574%, was a second notable relative detractor. Another notable relative detractor was our stake in ROBLOX (+3%). The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest contributor to performance versus the benchmark was stock picking in consumer discretionary. Stock picks and an underweight in consumer staples and stock picking and an overweight in materials also boosted the fund's relative performance.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in Alphabet (+137%). The company was the fund's largest holding at period end. A second notable relative contributor was our stake in Oracle (+48%). The stock was not held at period end. An overweight in Coca-Cola Consolidated (+53%) also helped. This period we increased our investment in Coca-Cola Consolidated. The company was one of our biggest holdings at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Notable changes in positioning include higher allocations to the consumer staples and materials sectors.&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, security selection was the primary detractor from the fund's performance versus the Russell 3000&#xae; Index for the fiscal year, especially within industrials. Security selection in communication services, primarily within the media &amp;amp; entertainment industry, also hampered the fund's result. Also hurting our result were stock picks and an overweight in financials.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The biggest individual relative detractor this period was avoiding Broadcom, a benchmark component that gained approximately 119%. Not owning Micron Technology, a benchmark component that gained about 574%, was a second notable relative detractor. Another notable relative detractor was our stake in ROBLOX (+3%). The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest contributor to performance versus the benchmark was stock picking in consumer discretionary. Stock picks and an underweight in consumer staples and stock picking and an overweight in materials also boosted the fund's relative performance.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in Alphabet (+137%). The company was the fund's largest holding at period end. A second notable relative contributor was our stake in Oracle (+48%). The stock was not held at period end. An overweight in Coca-Cola Consolidated (+53%) also helped. This period we increased our investment in Coca-Cola Consolidated. The company was one of our biggest holdings at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Notable changes in positioning include higher allocations to the consumer staples and materials sectors.&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, security selection was the primary contributor to the fund's performance versus the S&amp;amp;P MidCap 400 Index for the fiscal year, led by information technology. Stock picks in industrials, within the capital goods industry, also boosted relative performance. Also helping our relative result was an overweight in energy.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in Ciena (+638%). This period we considerably decreased our share count in Ciena. The company was one of the fund's biggest holdings this period. A non-benchmark stake in Western Digital gained 894% and was a second notable relative contributor. This was an investment we established this period. Another notable relative contributor was an overweight in Lumentum Holdings (+1374%). This period we decreased our stake in Lumentum Holdings.&#160;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, picks and an overweight in consumer discretionary detracted most from performance versus the benchmark. An underweight in information technology, primarily within the semiconductors &amp;amp; semiconductor equipment industry, also hampered the fund's result. Also hurting our result was stock selection in communication services, primarily within the media &amp;amp; entertainment industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The largest individual relative detractor was our non-benchmark stake in Brunello Cucinelli (-13%). A second notable relative detractor this period was avoiding MasTec, a benchmark component that gained roughly 210%. Another notable relative detractor was our non-benchmark stake in Molina Healthcare (-54%). The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Notable changes in positioning include decreased exposure to the consumer staples sector and a higher allocation to information technology.&lt;/span&gt;&lt;/div&gt;

Stock picks in industrials, within the capital goods industry, also boosted relative performance. Also helping our relative result was an overweight in energy.&lt;/span&gt;&lt;/div&gt;

This period we considerably decreased our share count in Ciena. The company was one of the fund's biggest holdings this period. A non-benchmark stake in Western Digital gained 894% and was a second notable relative contributor. This was an investment we established this period. Another notable relative contributor was an overweight in Lumentum Holdings (+1374%). This period we decreased our stake in Lumentum Holdings.&#160;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, picks and an overweight in consumer discretionary detracted most from performance versus the benchmark. An underweight in information technology, primarily within the semiconductors &amp;amp; semiconductor equipment industry, also hampered the fund's result. Also hurting our result was stock selection in communication services, primarily within the media &amp;amp; entertainment industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The largest individual relative detractor was our non-benchmark stake in Brunello Cucinelli (-13%). A second notable relative detractor this period was avoiding MasTec, a benchmark component that gained roughly 210%. Another notable relative detractor was our non-benchmark stake in Molina Healthcare (-54%). The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, security selection was the primary contributor to the fund's performance versus the S&amp;amp;P MidCap 400 Index for the fiscal year, led by information technology. Stock picks in industrials, within the capital goods industry, also boosted relative performance. Also helping our relative result was an overweight in energy.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in Ciena (+638%). This period we considerably decreased our share count in Ciena. The company was one of the fund's biggest holdings this period. A non-benchmark stake in Western Digital gained 894% and was a second notable relative contributor. This was an investment we established this period. Another notable relative contributor was an overweight in Lumentum Holdings (+1374%). This period we decreased our stake in Lumentum Holdings.&#160;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, picks and an overweight in consumer discretionary detracted most from performance versus the benchmark. An underweight in information technology, primarily within the semiconductors &amp;amp; semiconductor equipment industry, also hampered the fund's result. Also hurting our result was stock selection in communication services, primarily within the media &amp;amp; entertainment industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The largest individual relative detractor was our non-benchmark stake in Brunello Cucinelli (-13%). A second notable relative detractor this period was avoiding MasTec, a benchmark component that gained roughly 210%. Another notable relative detractor was our non-benchmark stake in Molina Healthcare (-54%). The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, security selection was the primary contributor to the fund's performance versus the S&amp;amp;P MidCap 400 Index for the fiscal year, led by information technology. Stock picks in industrials, within the capital goods industry, also boosted relative performance. Also helping our relative result was an overweight in energy.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in Ciena (+638%). This period we considerably decreased our share count in Ciena. The company was one of the fund's biggest holdings this period. A non-benchmark stake in Western Digital gained 894% and was a second notable relative contributor. This was an investment we established this period. Another notable relative contributor was an overweight in Lumentum Holdings (+1374%). This period we decreased our stake in Lumentum Holdings.&#160;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, picks and an overweight in consumer discretionary detracted most from performance versus the benchmark. An underweight in information technology, primarily within the semiconductors &amp;amp; semiconductor equipment industry, also hampered the fund's result. Also hurting our result was stock selection in communication services, primarily within the media &amp;amp; entertainment industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The largest individual relative detractor was our non-benchmark stake in Brunello Cucinelli (-13%). A second notable relative detractor this period was avoiding MasTec, a benchmark component that gained roughly 210%. Another notable relative detractor was our non-benchmark stake in Molina Healthcare (-54%). The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Notable changes in positioning include decreased exposure to the consumer staples sector and a higher allocation to information technology.&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, security selection was the primary contributor to the fund's performance versus the S&amp;amp;P MidCap 400 Index for the fiscal year, led by information technology. Stock picks in industrials, within the capital goods industry, also boosted relative performance. Also helping our relative result was an overweight in energy.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in Ciena (+638%). This period we considerably decreased our share count in Ciena. The company was one of the fund's biggest holdings this period. A non-benchmark stake in Western Digital gained 894% and was a second notable relative contributor. This was an investment we established this period. Another notable relative contributor was an overweight in Lumentum Holdings (+1374%). This period we decreased our stake in Lumentum Holdings.&#160;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, picks and an overweight in consumer discretionary detracted most from performance versus the benchmark. An underweight in information technology, primarily within the semiconductors &amp;amp; semiconductor equipment industry, also hampered the fund's result. Also hurting our result was stock selection in communication services, primarily within the media &amp;amp; entertainment industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The largest individual relative detractor was our non-benchmark stake in Brunello Cucinelli (-13%). A second notable relative detractor this period was avoiding MasTec, a benchmark component that gained roughly 210%. Another notable relative detractor was our non-benchmark stake in Molina Healthcare (-54%). The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Notable changes in positioning include decreased exposure to the consumer staples sector and a higher allocation to information technology.&lt;/span&gt;&lt;/div&gt;

Stock picking in financials and information technology also boosted the fund's relative result.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in GE Vernova (+193%). The company was among our biggest holdings. The second-largest relative contributor was an overweight in GE Aerospace (+45%). The stock was among our top holdings. Another notable relative contributor was a non-benchmark stake in Imperial Oil (+103%).&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest detractor from performance versus the benchmark was an underweight in information technology. An overweight in financials also hampered the fund's result. Also hurting our result were picks in real estate. Lastly, the fund's position in cash detracted.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Not owning Advanced Micro Devices, a benchmark component that gained 264%, was the biggest individual relative detractor. A non-benchmark stake in SAP returned roughly -42% and was a second notable relative detractor. An overweight in Boston Scientific (-44%) also hurt.&lt;/span&gt;&lt;/div&gt;

Stock picking in financials and information technology also boosted the fund's relative result.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in GE Vernova (+193%). The company was among our biggest holdings. The second-largest relative contributor was an overweight in GE Aerospace (+45%). The stock was among our top holdings. Another notable relative contributor was a non-benchmark stake in Imperial Oil (+103%).&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest detractor from performance versus the benchmark was an underweight in information technology. An overweight in financials also hampered the fund's result. Also hurting our result were picks in real estate. Lastly, the fund's position in cash detracted.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Not owning Advanced Micro Devices, a benchmark component that gained 264%, was the biggest individual relative detractor. A non-benchmark stake in SAP returned roughly -42% and was a second notable relative detractor. An overweight in Boston Scientific (-44%) also hurt.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Notable changes in positioning include increased exposure to the consumer discretionary sector and a lower allocation to financials.&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, security selection was the primary contributor to the fund's performance versus the benchmark S&amp;amp;P 500 index for the fiscal year, led by industrials. Stock picking in financials and information technology also boosted the fund's relative result.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in GE Vernova (+193%). The company was among our biggest holdings. The second-largest relative contributor was an overweight in GE Aerospace (+45%). The stock was among our top holdings. Another notable relative contributor was a non-benchmark stake in Imperial Oil (+103%).&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest detractor from performance versus the benchmark was an underweight in information technology. An overweight in financials also hampered the fund's result. Also hurting our result were picks in real estate. Lastly, the fund's position in cash detracted.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Not owning Advanced Micro Devices, a benchmark component that gained 264%, was the biggest individual relative detractor. A non-benchmark stake in SAP returned roughly -42% and was a second notable relative detractor. An overweight in Boston Scientific (-44%) also hurt.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Notable changes in positioning include increased exposure to the consumer discretionary sector and a lower allocation to financials.&lt;/span&gt;&lt;/div&gt;

Stock picking in financials and information technology also boosted the fund's relative result.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in GE Vernova (+193%). The company was among our biggest holdings. The second-largest relative contributor was an overweight in GE Aerospace (+45%). The stock was among our top holdings. Another notable relative contributor was a non-benchmark stake in Imperial Oil (+103%).&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest detractor from performance versus the benchmark was an underweight in information technology. An overweight in financials also hampered the fund's result. Also hurting our result were picks in real estate. Lastly, the fund's position in cash detracted.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Not owning Advanced Micro Devices, a benchmark component that gained 264%, was the biggest individual relative detractor. A non-benchmark stake in SAP returned roughly -42% and was a second notable relative detractor. An overweight in Boston Scientific (-44%) also hurt.&lt;/span&gt;&lt;/div&gt;

Stock picking in financials and information technology also boosted the fund's relative result.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The top individual relative contributor was an overweight in GE Vernova (+193%). The company was among our biggest holdings. The second-largest relative contributor was an overweight in GE Aerospace (+45%). The stock was among our top holdings. Another notable relative contributor was a non-benchmark stake in Imperial Oil (+103%).&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest detractor from performance versus the benchmark was an underweight in information technology. An overweight in financials also hampered the fund's result. Also hurting our result were picks in real estate. Lastly, the fund's position in cash detracted.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Not owning Advanced Micro Devices, a benchmark component that gained 264%, was the biggest individual relative detractor. A non-benchmark stake in SAP returned roughly -42% and was a second notable relative detractor. An overweight in Boston Scientific (-44%) also hurt.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Notable changes in positioning include increased exposure to the consumer discretionary sector and a lower allocation to financials.&lt;/span&gt;&lt;/div&gt;
