&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;For the twelve months ended November 30, 2025, Class A shares of the MFS Growth Fund (fund) provided a total return of &lt;span style="white-space:nowrap"&gt;12.24%&lt;/span&gt;, at net asset value.

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. In the US, a pro-growth tax and spending bill was signed into law, while in Europe, renewed focus on defense and infrastructure spending brightened the outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs. Optimism over artificial intelligence remained quite high.&lt;/div&gt; &lt;/li&gt;
&lt;li style="padding-left: 2pt; margin-left: 16pt; margin-top: 6pt; font-family: 'Arial'; font-weight: normal; font-size: 10pt; line-height: 11pt; color: rgb(0, 0, 0); list-style-type: disc; padding-right: 6pt;"&gt;
&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. US tariffs remained high on goods from countries such as India and Brazil.&#160;&lt;/div&gt; &lt;/li&gt;
&lt;li style="padding-left: 2pt; margin-left: 16pt; margin-top: 6pt; font-family: 'Arial'; font-weight: normal; font-size: 10pt; line-height: 11pt; color: rgb(0, 0, 0); list-style-type: disc; padding-right: 6pt;"&gt;
&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Moderating inflation pressures allowed many global central banks to ease monetary policy during the period. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September.&lt;/div&gt; &lt;/li&gt;

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;In fixed income markets, global bond yields peaked in mid-January, then gradually declined, ending the reporting period lower than at the start of the period,&lt;span style="white-space:nowrap"&gt;&#160;&lt;/span&gt;while experiencing&lt;span style="white-space:nowrap"&gt;&#160;&lt;/span&gt;waves of volatility in between.

&lt;div style="margin-top: 0px; margin-bottom: 0px;"&gt;For the twelve months ended November 30, 2025, Class B shares of the MFS Growth Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;11.40%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;13.59%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 1000&lt;sup&gt;&#xae;&lt;/sup&gt; Growth Index, generated a return of &lt;span style="white-space: nowrap;"&gt;20.35%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="break-inside: avoid; margin-top: -1pt; border: 1pt solid rgb(128, 128, 128);"&gt;
&lt;ul style="break-inside: avoid; padding: 0; margin: -3pt 0 4pt 0;"&gt;

&lt;div style="margin-top: 0px; margin-bottom: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. In the US, a pro-growth tax and spending bill was signed into law, while in Europe, renewed focus on defense and infrastructure spending brightened the outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs. Optimism over artificial intelligence remained quite high.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="padding-left: 2pt; margin-left: 16pt; margin-top: 6pt; font-family: 'Arial'; font-weight: normal; font-size: 10pt; line-height: 11pt; color: rgb(0, 0, 0); list-style-type: disc; padding-right: 6pt;"&gt;
&lt;div style="margin-top: 0px; margin-bottom: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. US tariffs remained high on goods from countries such as India and Brazil.&#160;&lt;/div&gt;
&lt;/li&gt;
&lt;li style="padding-left: 2pt; margin-left: 16pt; margin-top: 6pt; font-family: 'Arial'; font-weight: normal; font-size: 10pt; line-height: 11pt; color: rgb(0, 0, 0); list-style-type: disc; padding-right: 6pt;"&gt;
&lt;div style="margin-top: 0px; margin-bottom: 0px;"&gt;Moderating inflation pressures allowed many global central banks to ease monetary policy during the period. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September.&lt;/div&gt;
&lt;/li&gt;
&lt;li style="padding-left: 2pt; margin-left: 16pt; margin-top: 6pt; font-family: 'Arial'; font-weight: normal; font-size: 10pt; line-height: 11pt; color: rgb(0, 0, 0); list-style-type: disc; padding-right: 6pt;"&gt;
&lt;div style="margin-top: 0px; margin-bottom: 0px;"&gt;In fixed income markets, global bond yields peaked in mid-January, then gradually declined, ending the reporting period lower than at the start of the period,&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;while experiencing&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;waves of volatility in between. Credit&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;spreads&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;remained tight and near historical lows, despite a brief widening in April and May due to tariff concerns.&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;US bond market volatility, as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index, ended near session lows after rising&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;around the time of&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;the US presidential election and the start of the trade war.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div style="margin-top: 0px; margin-bottom: 0px;"&gt;Security selection and an underweight position in the consumer staples sector was another area of relative strength.&lt;/div&gt;

&lt;div style="margin-top: 0px; margin-bottom: 0px;"&gt;Security selection and an overweight position in the financials sector also detracted from relative returns. Weak stock selection within the health care sector was another factor that held back relative performance.&lt;/div&gt;

&lt;div style="margin-top: 0px; margin-bottom: 0px;"&gt;For the twelve months ended November 30, 2025, Class C shares of the MFS Growth Fund (fund) provided a total return of &lt;span style="white-space: nowrap;"&gt;11.40%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space: nowrap;"&gt;13.59%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup&gt;&#xae;&lt;/sup&gt; Index. The fund's other benchmark, the Russell 1000&lt;sup&gt;&#xae;&lt;/sup&gt; Growth Index, generated a return of &lt;span style="white-space: nowrap;"&gt;20.35%&lt;/span&gt;.&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div style="margin-top: 0px; margin-bottom: 0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. In the US, a pro-growth tax and spending bill was signed into law, while in Europe, renewed focus on defense and infrastructure spending brightened the outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs. Optimism over artificial intelligence remained quite high.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="margin-top: 0px; margin-bottom: 0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. US tariffs remained high on goods from countries such as India and Brazil.&#160;&lt;/div&gt;
&lt;/li&gt;

&lt;div style="margin-top: 0px; margin-bottom: 0px;"&gt;Moderating inflation pressures allowed many global central banks to ease monetary policy during the period. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September.&lt;/div&gt;
&lt;/li&gt;

&lt;div style="margin-top: 0px; margin-bottom: 0px;"&gt;In fixed income markets, global bond yields peaked in mid-January, then gradually declined, ending the reporting period lower than at the start of the period,&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;while experiencing&lt;span style="white-space: nowrap;"&gt;&#160;&lt;/span&gt;waves of volatility in between.

&lt;div style="margin-top: 0px; margin-bottom: 0px;"&gt;Security selection and an overweight position in the financials sector also detracted from relative returns. Weak stock selection within the health care sector was another factor that held back relative performance.&lt;/div&gt;

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. In the US, a pro-growth tax and spending bill was signed into law, while in Europe, renewed focus on defense and infrastructure spending brightened the outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs. Optimism over artificial intelligence remained quite high.&lt;/div&gt; &lt;/li&gt;

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. US tariffs remained high on goods from countries such as India and Brazil.&#160;&lt;/div&gt; &lt;/li&gt;

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Moderating inflation pressures allowed many global central banks to ease monetary policy during the period.

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;For the twelve months ended November 30, 2025, Class R1 shares of the MFS Growth Fund (fund) provided a total return of &lt;span style="white-space:nowrap"&gt;11.40%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space:nowrap"&gt;13.59%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup&gt;&#xae;&lt;/sup&gt; Index.

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. In the US, a pro-growth tax and spending bill was signed into law, while in Europe, renewed focus on defense and infrastructure spending brightened the outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs. Optimism over artificial intelligence remained quite high.&lt;/div&gt; &lt;/li&gt;
&lt;li style="padding-left: 2pt; margin-left: 16pt; margin-top: 6pt; font-family: 'Arial'; font-weight: normal; font-size: 10pt; line-height: 11pt; color: rgb(0, 0, 0); list-style-type: disc; padding-right: 6pt;"&gt;
&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. US tariffs remained high on goods from countries such as India and Brazil.&#160;&lt;/div&gt; &lt;/li&gt;

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Moderating inflation pressures allowed many global central banks to ease monetary policy during the period. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September.&lt;/div&gt; &lt;/li&gt;

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;In fixed income markets, global bond yields peaked in mid-January, then gradually declined, ending the reporting period lower than at the start of the period,&lt;span style="white-space:nowrap"&gt;&#160;&lt;/span&gt;while experiencing&lt;span style="white-space:nowrap"&gt;&#160;&lt;/span&gt;waves of volatility in between.

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Security selection and an overweight position in the financials sector also detracted from relative returns.

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;For the twelve months ended November 30, 2025, Class R2 shares of the MFS Growth Fund (fund) provided a total return of &lt;span style="white-space:nowrap"&gt;11.95%&lt;/span&gt;, at net asset value.

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. In the US, a pro-growth tax and spending bill was signed into law, while in Europe, renewed focus on defense and infrastructure spending brightened the outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs. Optimism over artificial intelligence remained quite high.&lt;/div&gt; &lt;/li&gt;

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. US tariffs remained high on goods from countries such as India and Brazil.&#160;&lt;/div&gt; &lt;/li&gt;

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Moderating inflation pressures allowed many global central banks to ease monetary policy during the period. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September.&lt;/div&gt; &lt;/li&gt;

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;In fixed income markets, global bond yields peaked in mid-January, then gradually declined, ending the reporting period lower than at the start of the period,&lt;span style="white-space:nowrap"&gt;&#160;&lt;/span&gt;while experiencing&lt;span style="white-space:nowrap"&gt;&#160;&lt;/span&gt;waves of volatility in between.

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;For the twelve months ended November 30, 2025, Class R3 shares of the MFS Growth Fund (fund) provided a total return of &lt;span style="white-space:nowrap"&gt;12.23%&lt;/span&gt;, at net asset value.

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. In the US, a pro-growth tax and spending bill was signed into law, while in Europe, renewed focus on defense and infrastructure spending brightened the outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs. Optimism over artificial intelligence remained quite high.&lt;/div&gt; &lt;/li&gt;

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. US tariffs remained high on goods from countries such as India and Brazil.&#160;&lt;/div&gt; &lt;/li&gt;

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Moderating inflation pressures allowed many global central banks to ease monetary policy during the period. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September.&lt;/div&gt; &lt;/li&gt;

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;In fixed income markets, global bond yields peaked in mid-January, then gradually declined, ending the reporting period lower than at the start of the period,&lt;span style="white-space:nowrap"&gt;&#160;&lt;/span&gt;while experiencing&lt;span style="white-space:nowrap"&gt;&#160;&lt;/span&gt;waves of volatility in between.

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;For the twelve months ended November 30, 2025, Class R4 shares of the MFS Growth Fund (fund) provided a total return of &lt;span style="white-space:nowrap"&gt;12.52%&lt;/span&gt;, at net asset value. This compares with a return of &lt;span style="white-space:nowrap"&gt;13.59%&lt;/span&gt; for the fund&#x2019;s benchmark, the Russell 3000&lt;sup&gt;&#xae;&lt;/sup&gt; Index.

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. In the US, a pro-growth tax and spending bill was signed into law, while in Europe, renewed focus on defense and infrastructure spending brightened the outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs. Optimism over artificial intelligence remained quite high.&lt;/div&gt; &lt;/li&gt;

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. US tariffs remained high on goods from countries such as India and Brazil.&#160;&lt;/div&gt; &lt;/li&gt;

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Moderating inflation pressures allowed many global central banks to ease monetary policy during the period. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September.&lt;/div&gt; &lt;/li&gt;

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;In fixed income markets, global bond yields peaked in mid-January, then gradually declined, ending the reporting period lower than at the start of the period,&lt;span style="white-space:nowrap"&gt;&#160;&lt;/span&gt;while experiencing&lt;span style="white-space:nowrap"&gt;&#160;&lt;/span&gt;waves of volatility in between.

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;For the twelve months ended November 30, 2025, Class R6 shares of the MFS Growth Fund (fund) provided a total return of &lt;span style="white-space:nowrap"&gt;12.62%&lt;/span&gt;, at net asset value.

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Global equity markets reached record levels during the period, withstanding considerable volatility amid tariffs, geopolitical conflict and high levels of uncertainty. In the US, a pro-growth tax and spending bill was signed into law, while in Europe, renewed focus on defense and infrastructure spending brightened the outlook. In Japan, the election of a pro-growth prime minister sent stocks to new highs. Optimism over artificial intelligence remained quite high.&lt;/div&gt; &lt;/li&gt;
&lt;li style="padding-left: 2pt; margin-left: 16pt; margin-top: 6pt; font-family: 'Arial'; font-weight: normal; font-size: 10pt; line-height: 11pt; color: rgb(0, 0, 0); list-style-type: disc; padding-right: 6pt;"&gt;
&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Considerable progress was made in trade talks between the US and many major trading partners, with a fragile truce between the US and China extended through late 2026. US tariffs remained high on goods from countries such as India and Brazil.&#160;&lt;/div&gt; &lt;/li&gt;
&lt;li style="padding-left: 2pt; margin-left: 16pt; margin-top: 6pt; font-family: 'Arial'; font-weight: normal; font-size: 10pt; line-height: 11pt; color: rgb(0, 0, 0); list-style-type: disc; padding-right: 6pt;"&gt;
&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;Moderating inflation pressures allowed many global central banks to ease monetary policy during the period. Amid a difficult policymaking environment and slower job growth, the Federal Reserve resumed easing policy in September.&lt;/div&gt; &lt;/li&gt;

&lt;div style="margin-top:0px;margin-bottom:0px;"&gt;In fixed income markets, global bond yields peaked in mid-January, then gradually declined, ending the reporting period lower than at the start of the period,&lt;span style="white-space:nowrap"&gt;&#160;&lt;/span&gt;while experiencing&lt;span style="white-space:nowrap"&gt;&#160;&lt;/span&gt;waves of volatility in between.
