MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE

* For the twelve months ended November 30, 2025, Class A shares of the MFS Global Opportunistic Bond Fund (fund) provided a total return of 4.65%, at net asset value. This compares with a return of 4.28% for the fund's benchmark, the Bloomberg Global Aggregate Index (USD Hedged).

* 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.

* 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. 

* 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.

* 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, while experiencing waves of volatility in between. Credit spreads remained tight and near historical lows, despite a brief widening in April and May due to tariff concerns. US bond market volatility, as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index, ended near session lows after rising around the time of the US presidential election and the start of the trade war.

* Top contributors to performance relative to the Bloomberg Global Aggregate Index (USD Hedged):

The fund's exposure to collateralized loan obligations (CLOs), for which the benchmark has no exposure, and its underweight allocation to the treasury sector supported relative performance. An overweight exposure to the industrials sector also benefited relative returns. From a credit quality perspective, the fund's out-of-benchmark exposure to below investment grade bonds, and an overweight exposure to BBB -rated bonds, further strengthened relative results. Regional allocation also added to relative performance, particularly exposures to the United States and Europe.

Favorable security selection within both the treasury and industrial sectors benefited relative returns. From a credit quality perspective, security selection among BBB -rated issuers supported relative results. The fund's underweight exposure to the US dollar and yield curve positioning, particularly along the USD yield curve, were additional factors that contributed to relative performance.

* Top detractors from performance relative to the Bloomberg Global Aggregate Index (USD Hedged):

Foreign exchange decisions, most notably from the fund's overweight exposure to the euro, Japanese yen and Chinese yuan currencies, weighed on relative performance. Yield curve positioning along both the Chinese and Japanese yield curves also held back relative performance.

#### FUND PERFORMANCE
 ***The fund's past performance is not a good predictor of the fund's future performance.*** The graph and table below do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. The graph and table below assume reinvestment of dividends and capital gain distributions.

#### Notes to Fund Performance
Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown. Without such subsidies and waivers the fund's performance results would be less favorable.

Performance information prior to April 30, 2021, reflects time periods when the fund (i) had a policy of primarily investing in investment grade quality debt instruments and (ii) did not have a policy to engage in a currency hedging strategy to primarily expose the fund to the U.S. dollar. The fund's investment policies and strategies changed effective April 30, 2021.

From time to time the fund may receive proceeds from litigation settlements, without which performance would be lower.

* Top contributors to performance relative to the Bloomberg Global Aggregate Index (USD Hedged):

The fund's exposure to collateralized loan obligations (CLOs), for which the benchmark has no exposure, and its underweight allocation to the treasury sector supported relative performance. An overweight exposure to the industrials sector also benefited relative returns. From a credit quality perspective, the fund's out-of-benchmark exposure to below investment grade bonds, and an overweight exposure to BBB -rated bonds, further strengthened relative results. Regional allocation also added to relative performance, particularly exposures to the United States and Europe.

Favorable security selection within both the treasury and industrial sectors benefited relative returns. From a credit quality perspective, security selection among BBB -rated issuers supported relative results. The fund's underweight exposure to the US dollar and yield curve positioning, particularly along the USD yield curve, were additional factors that contributed to relative performance.

* Top detractors from performance relative to the Bloomberg Global Aggregate Index (USD Hedged):

Foreign exchange decisions, most notably from the fund's overweight exposure to the euro, Japanese yen and Chinese yuan currencies, weighed on relative performance. Yield curve positioning along both the Chinese and Japanese yield curves also held back relative performance.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE

* For the twelve months ended November 30, 2025, Class I shares of the MFS Global Opportunistic Bond Fund (fund) provided a total return of 4.91%, at net asset value. This compares with a return of 4.28% for the fund's benchmark, the Bloomberg Global Aggregate Index (USD Hedged).

* 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.

* 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. 

* 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.

* 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, while experiencing waves of volatility in between. Credit spreads remained tight and near historical lows, despite a brief widening in April and May due to tariff concerns. US bond market volatility, as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index, ended near session lows after rising around the time of the US presidential election and the start of the trade war.

* Top contributors to performance relative to the Bloomberg Global Aggregate Index (USD Hedged):

The fund's exposure to collateralized loan obligations (CLOs), for which the benchmark has no exposure, and its underweight allocation to the treasury sector supported relative performance.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE

* For the twelve months ended November 30, 2025, Class R2 shares of the MFS Global Opportunistic Bond Fund (fund) provided a total return of 4.39%, at net asset value. This compares with a return of 4.28% for the fund's benchmark, the Bloomberg Global Aggregate Index (USD Hedged).

* 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.

* 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. 

* 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.

* 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, while experiencing waves of volatility in between. Credit spreads remained tight and near historical lows, despite a brief widening in April and May due to tariff concerns. US bond market volatility, as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index, ended near session lows after rising around the time of the US presidential election and the start of the trade war.

* Top contributors to performance relative to the Bloomberg Global Aggregate Index (USD Hedged):

The fund's exposure to collateralized loan obligations (CLOs), for which the benchmark has no exposure, and its underweight allocation to the treasury sector supported relative performance. An overweight exposure to the industrials sector also benefited relative returns. From a credit quality perspective, the fund's out-of-benchmark exposure to below investment grade bonds, and an overweight exposure to BBB -rated bonds, further strengthened relative results. Regional allocation also added to relative performance, particularly exposures to the United States and Europe.

Favorable security selection within both the treasury and industrial sectors benefited relative returns. From a credit quality perspective, security selection among BBB -rated issuers supported relative results. The fund's underweight exposure to the US dollar and yield curve positioning, particularly along the USD yield curve, were additional factors that contributed to relative performance.

* Top detractors from performance relative to the Bloomberg Global Aggregate Index (USD Hedged):

Foreign exchange decisions, most notably from the fund's overweight exposure to the euro, Japanese yen and Chinese yuan currencies, weighed on relative performance. Yield curve positioning along both the Chinese and Japanese yield curves also held back relative performance.

Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown. Without such subsidies and waivers the fund's performance results would be less favorable.

Performance information prior to April 30, 2021, reflects time periods when the fund (i) had a policy of primarily investing in investment grade quality debt instruments and (ii) did not have a policy to engage in a currency hedging strategy to primarily expose the fund to the U.S. dollar. The fund's investment policies and strategies changed effective April 30, 2021.

From time to time the fund may receive proceeds from litigation settlements, without which performance would be lower.

Ratings are assigned using Moody's, Fitch, and Standard & Poor's and applying a hierarchy: If all 3 agencies rate a security, the middle rating is assigned; if 2 agencies rate a security, the lower rating is assigned. If none of the 3 agencies rate a security, we use DBRS Morningstar. If none of the 4 agencies rate a security, we use Kroll Bond Rating Agency. Ratings are shown in the S&P and Fitch scale (e.g., AAA). All ratings are subject to change.

Portfolio Composition presents the value of securities, including equivalent exposure of derivative positions. Equivalent exposure is a reasonable approximation of the amount of the underlying asset the portfolio would have to hold to have the same price sensitivity of the derivative contract.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE

* For the twelve months ended November 30, 2025, Class R6 shares of the MFS Global Opportunistic Bond Fund (fund) provided a total return of 5.00%, at net asset value. This compares with a return of 4.28% for the fund's benchmark, the Bloomberg Global Aggregate Index (USD Hedged).

* 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.

* 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. 

* 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.

* 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, while experiencing waves of volatility in between. Credit spreads remained tight and near historical lows, despite a brief widening in April and May due to tariff concerns. US bond market volatility, as measured by the Merrill Lynch Option Volatility Estimate (MOVE) Index, ended near session lows after rising around the time of the US presidential election and the start of the trade war.

* Top contributors to performance relative to the Bloomberg Global Aggregate Index (USD Hedged):

The fund's exposure to collateralized loan obligations (CLOs), for which the benchmark has no exposure, and its underweight allocation to the treasury sector supported relative performance. An overweight exposure to the industrials sector also benefited relative returns. From a credit quality perspective, the fund's out-of-benchmark exposure to below investment grade bonds, and an overweight exposure to BBB -rated bonds, further strengthened relative results. Regional allocation also added to relative performance, particularly exposures to the United States and Europe.

Favorable security selection within both the treasury and industrial sectors benefited relative returns. From a credit quality perspective, security selection among BBB -rated issuers supported relative results. The fund's underweight exposure to the US dollar and yield curve positioning, particularly along the USD yield curve, were additional factors that contributed to relative performance.

* Top detractors from performance relative to the Bloomberg Global Aggregate Index (USD Hedged):

Foreign exchange decisions, most notably from the fund's overweight exposure to the euro, Japanese yen and Chinese yuan currencies, weighed on relative performance. Yield curve positioning along both the Chinese and Japanese yield curves also held back relative performance.

#### Notes to Fund Performance
Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown. Without such subsidies and waivers the fund's performance results would be less favorable.

Performance information prior to April 30, 2021, reflects time periods when the fund (i) had a policy of primarily investing in investment grade quality debt instruments and (ii) did not have a policy to engage in a currency hedging strategy to primarily expose the fund to the U.S. dollar. The fund's investment policies and strategies changed effective April 30, 2021.

From time to time the fund may receive proceeds from litigation settlements, without which performance would be lower.

\*This amount reflects the fees billed to MFS and MFS Related Entities for non-audit services relating directly to the operations and financial reporting of the Fund (portions of which services also related to the operations and financial reporting of other funds within the MFS Funds complex).

# This amount reflects the aggregate fees billed by E&Y for non-audit services rendered to the Fund and for non- audit services rendered to MFS and the MFS Related Entities.

<sup>1</sup> The fees included under "Audit-Related Fees" are fees related to assurance and related services that are reasonably related to the performance of the audit or review of financial statements, but not reported under ''Audit Fees,'' including accounting consultations, agreed-upon procedure reports, attestation reports, comfort letters and internal control reviews.

<sup>2</sup> The fees included under "Tax Fees" are fees associated with tax compliance, tax advice and tax planning, including services relating to the filing or amendment of federal, state or local income tax returns, regulated investment company qualification reviews and tax distribution and analysis.

<sup>3</sup> The fees included under "All Other Fees" are fees for products and services provided by E&Y other than those reported under "Audit Fees," "Audit-Related Fees" and "Tax Fees".

**Item 4(e)(1):**

Set forth below are the policies and procedures established by the Audit Committee of the Board of Trustees relating to the pre-approval of audit and non-audit related services:

To the extent required by applicable law, pre-approval by the Audit Committee of the Board is needed for all audit and permissible non-audit services rendered to the Fund and all permissible non-audit services rendered to MFS or MFS Related Entities if the services relate directly to the operations and financial reporting of the Registrant. Pre- approval is currently on an engagement-by-engagement basis. In the event pre-approval of such services is necessary between regular meetings of the Audit Committee and it is not practical to wait to seek pre-approval at the next regular meeting of the Audit Committee, pre-approval of such services may be referred to the Chair of the Audit Committee for approval; provided that the Chair may not pre-approve any individual engagement for such services exceeding $50,000 or multiple engagements for such services in the aggregate exceeding $100,000 between such regular meetings of the Audit Committee. Any engagement pre-approved by the Chair between regular meetings of the Audit Committee shall be presented for ratification by the entire Audit Committee at its next regularly scheduled meeting.

**Item 4(e)(2):**

None, or 0%, of the services relating to the Audit-Related Fees, Tax Fees and All Other Fees paid by the Fund and MFS and MFS Related Entities relating directly to the operations and financial reporting of the Registrant disclosed above were approved by the audit committee pursuant to paragraphs (c)(7)(i)(C) of Rule 2-01 of Regulation S-X (which permits audit committee approval after the start of the engagement with respect to services other than audit, review or attest services, if certain conditions are satisfied).

**Item 4(f):**

Not applicable.

**Item 4(h):**

The Registrant's Audit Committee has considered whether the provision by a Registrant's independent registered public accounting firm of non-audit services to MFS and MFS Related Entities that were not pre-approved by the Committee (because such services were provided prior to the effectiveness of SEC rules requiring pre-approval or because such services did not relate directly to the operations and financial reporting of the Registrant) was compatible with maintaining the independence of the independent registered public accounting firm as the Registrant's principal auditors.

**Item 4(i):**

Not applicable.

**Item 4(j):**

Not applicable.

MFS Global Opportunistic Bond Fund

**Notes to Financial Statements**

**(1) Business and Organization**

MFS Global Opportunistic Bond Fund (the fund) is a diversified series of MFS Series Trust X (the trust). The trust is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended, as an open-end management investment company.

The fund is an investment company and accordingly follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 Financial Services - Investment Companies.

**(2) Significant Accounting Policies**

**General** — The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. In the preparation of these financial statements, management has evaluated subsequent events occurring after the date of the fund's Statement of Assets and Liabilities through the date that the financial statements were issued. The fund invests in foreign securities, including securities of emerging market issuers. Investments in foreign securities are vulnerable to the effects of changes in the relative values of the local currency and the U.S. dollar and to the effects of changes in each country's market, economic, industrial, political, regulatory, geopolitical, environmental, public health, and other conditions. Investments tied economically to emerging markets, especially frontier markets, can involve additional and greater risks than the risks associated with investments in developed markets. Emerging markets can have less developed markets, greater custody and operational risk, less developed legal, regulatory, and accounting systems, greater government involvement in the economy, greater risk of new or inconsistent government treatment of or restrictions on issuers and instruments, and greater political, social, geopolitical, and economic instability than developed markets.

The fund may invest up to 35% of its total assets in the securities of issuers in any particular industry if, at the time of investment, that industry represents more than 20% of the global bond market, as a whole, as measured by an index determined by MFS to be an appropriate measure of the global bond market. At November 30, 2025, the fund did not have more than 25% of its assets invested in any one industry.

**Operating Segments** — In this reporting period, the fund adopted FASB Accounting Standards Update 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures ("ASU 2023-07"). Adoption of the new standard impacted financial statement disclosures only and did not affect the fund's financial position or the results of its operations. An operating segment is a component of a public entity that engages in business activities from which it may recognize revenues and incur expenses, has operating results that are regularly reviewed by the entity's chief operating decision maker (CODM) in making resource allocation decisions and assessing segment performance, and for which discrete financial information is available. The fund represents a single operating segment and the Chairman's Committee of the fund's adviser acts as the segment's CODM. The fund's total returns, expense ratios, and changes in net assets which are used by the CODM to assess segment performance and to make resource allocation decisions to the segment are consistent with that presented within the fund's financial statements.

**Balance Sheet Offsetting** — The fund's accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the International Swaps and Derivatives Association (ISDA) Master Agreement, or similar agreement, does not result in an offset of reported amounts of financial assets and financial liabilities in the Statement of Assets and Liabilities across transactions between the fund and the applicable counterparty. The fund's right to setoff may be restricted or prohibited by the bankruptcy or insolvency laws of the particular jurisdiction to which a specific master netting agreement counterparty is subject. Balance sheet offsetting disclosures, to the extent applicable to the fund, have been included in the fund's Significant Accounting Policies note under the captions for each of the fund's in-scope financial instruments and transactions.

**Investment Valuations** — Subject to its oversight, the fund's Board of Trustees has delegated primary responsibility for determining or causing to be determined the value of the fund's investments to MFS as the fund's adviser, pursuant to the fund's valuation policy and procedures which have been adopted by the adviser and approved by the Board. In accordance with Rule 2a-5 under the Investment Company Act of 1940, the Board of Trustees designated the adviser as the "valuation designee" of the fund. If the adviser, as valuation designee, determines that reliable market quotations are not readily available for an investment, the investment is valued at fair value as determined in good faith by the adviser in accordance with the adviser's fair valuation policy and procedures.

Under the fund's valuation policy and procedures, debt instruments and floating rate loans, including restricted debt instruments, are generally valued at an evaluated or composite bid as provided by a third-party pricing service. Short-term instruments with a maturity at issuance of 60 days or less may be valued at amortized cost, which approximates market value. Exchange-traded options are

*Notes to Financial Statements - continued* 

generally valued at the last sale or official closing price on their primary exchange as provided by a third-party pricing service. Exchange-traded options for which there were no sales reported that day are generally valued at the last daily bid quotation on their primary exchange as provided by a third-party pricing service. For put options, the position may be valued at the last daily ask quotation if there are no trades reported during the day. Options not traded on an exchange are generally valued at a broker/dealer bid quotation. Foreign currency options are generally valued at valuations provided by a third-party pricing service. Futures contracts are generally valued at last posted settlement price on their primary exchange as provided by a third-party pricing service. Futures contracts for which there were no trades that day for a particular position are generally valued at the closing bid quotation on their primary exchange as provided by a third-party pricing service. Forward foreign currency exchange contracts are generally valued at the mean of bid and asked prices for the time period interpolated from rates provided by a third-party pricing service for proximate time periods. Swap agreements are generally valued using valuations provided by a third-party pricing service, which for cleared swaps includes an evaluation of any trading activity at the clearinghouses. Open-end investment companies are generally valued at net asset value per share. The values of foreign securities and other assets and liabilities expressed in foreign currencies are converted to U.S. dollars using the mean of bid and asked prices for rates provided by a third-party pricing service.

Under the fund's valuation policy and procedures, market quotations are not considered to be readily available for debt instruments, floating rate loans, and many types of derivatives. These investments are generally valued at fair value based on information from third-party pricing services or otherwise determined by the adviser in accordance with the adviser's fair valuation policy and procedures. Securities and other assets generally valued on the basis of information from a third-party pricing service may also be valued at a broker/dealer bid quotation. In determining values, third-party pricing services can utilize both transaction data and market information such as yield, quality, coupon rate, maturity, type of issue, trading characteristics, spreads and other market data. Pricing services generally value debt instruments assuming orderly transactions of institutional round lot sizes, but a fund may hold or transact in such securities in smaller, odd lot sizes. In instances where a fund holds an odd lot size position in a debt instrument, such position will typically be valued using the pricing agent's institutional round lot price for the debt instrument. Odd lots may trade at lower prices than institutional round lots, and the fund may receive different prices when it sells odd lot positions than it would receive for sales of institutional round lot positions. An investment may also be valued at fair value if the adviser determines that the investment's value has been materially affected by events occurring after the close of the exchange or market on which the investment is principally traded (such as foreign exchange or market) and prior to the determination of the fund's net asset value, or after the halt of trading of a specific security where trading does not resume prior to the close of the exchange or market on which the security is principally traded. The adviser generally relies on third-party pricing services or other information (such as the correlation with price movements of similar securities in the same or other markets; the type, cost and investment characteristics of the security; the business and financial condition of the issuer; and trading and other market data) to assist in determining whether to fair value and at what value to fair value an investment. The value of an investment for purposes of calculating the fund's net asset value can differ depending on the source and method used to determine value. When fair valuation is used, the value of an investment used to determine the fund's net asset value may differ from quoted or published prices for the same investment. There can be no assurance that the fund could obtain the fair value assigned to an investment if it were to sell the investment at the same time at which the fund determines its net asset value per share.

Various inputs are used in determining the value of the fund's assets or liabilities. These inputs are categorized into three broad levels. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The fund's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment. Level 1 includes unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 includes other significant observable market-based inputs (including quoted prices for similar securities, interest rates, prepayment speed, and credit risk). Level 3 includes significant unobservable inputs, which may include the adviser's own assumptions in determining the fair value of investments. Other financial instruments are derivative instruments, such as futures contracts, forward foreign currency exchange contracts, swap agreements, and written options. The following is a summary of the levels used as of November 30, 2025 in valuing the fund's assets and liabilities:

For further information regarding security characteristics, see the Portfolio of Investments.

**Inflation-Adjusted Debt Securities** — The fund invests in inflation-adjusted debt securities issued by the U.S. Treasury. The principal value of these debt securities is adjusted through income according to changes in the Consumer Price Index. These debt securities typically pay a fixed rate of interest, but this fixed rate is applied to the inflation-adjusted principal amount. The principal paid at maturity of the debt security is typically equal to the inflation-adjusted principal amount, or the security's original par value, whichever is greater. Other types of inflation-adjusted securities may use other methods to adjust for other measures of inflation.

**Foreign Currency Translation** — Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions or on the reporting date for foreign denominated receivables and payables. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on receivables, payables, income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed.

**Derivatives** — The fund uses derivatives primarily to increase or decrease exposure to a particular market or segment of the market, or security, to increase or decrease interest rate or currency exposure, or as alternatives to direct investments. Derivatives are used for hedging or non-hedging purposes. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. When the fund uses derivatives as an investment to increase market exposure, or for hedging purposes, gains and losses from derivative instruments may be substantially greater than the derivative's original cost.

The derivative instruments used by the fund during the period were written options, purchased options, futures contracts, forward foreign currency exchange contracts, and swap agreements. Depending on the type of derivative, a fund may exit a derivative position by entering into an offsetting transaction with a counterparty or exchange, negotiating an agreement with the derivative counterparty, or novating the position to a third party. The fund's period end derivatives, as presented in the Portfolio of Investments and the associated Derivative Contract tables, generally are indicative of the volume of its derivative activity during the period.

The following table presents, by major type of derivative contract, the fair value, on a gross basis, of the asset and liability components of derivatives held by the fund at November 30, 2025 as reported in the Statement of Assets and Liabilities:

Derivative counterparty credit risk is managed through formal evaluation of the creditworthiness of all potential counterparties. On certain, but not all, uncleared derivatives, the fund attempts to reduce its exposure to counterparty credit risk whenever possible by entering into an ISDA Master Agreement on a bilateral basis. The ISDA Master Agreement gives each party to the agreement the right to terminate all transactions traded under such agreement if there is a specified deterioration in the credit quality of the other party. Upon an event of default or a termination of the ISDA Master Agreement, the non-defaulting party has the right to close out all transactions traded under such agreement and to net amounts owed under each agreement to one net amount payable by one party to the other. This right to close out and net payments across all transactions traded under the ISDA Master Agreement could result in a reduction of the fund's credit risk to such counterparty equal to any amounts payable by the fund under the applicable transactions, if any.

Collateral and margin requirements differ by type of derivative. For exchange-traded and cleared derivatives (e.g., futures contracts, cleared swaps, and exchange-traded options), margin requirements are set by the exchange or clearing broker and the clearing house and collateral, in the form of cash or securities, is posted by the fund directly with the exchange or clearing broker. Collateral terms are counterparty agreement specific for uncleared derivatives (e.g., forward foreign currency exchange contracts, uncleared swap agreements, and uncleared options). Collateral, in the form of cash and securities, is held in segregated accounts with the fund's custodian in connection with these agreements. For derivatives traded under an ISDA Master Agreement, which contains a credit support annex, the collateral requirements are netted across all transactions traded under such counterparty-specific agreement and an amount is posted from one party to the other to collateralize such obligations. Cash that has been segregated or delivered to cover the fund's collateral or margin obligations under derivative contracts, if any, will be reported separately in the Statement of Assets and Liabilities as restricted cash for uncleared derivatives and/or deposits with brokers for exchange-traded or cleared

derivatives. Securities pledged as collateral or margin for the same purpose, if any, are noted in the Portfolio of Investments. The fund may be required to make payments of interest on uncovered collateral or margin obligations with the broker.

(b) The amount presented here may be less than the total amount of collateral posted by the counterparty/by the fund. Excess collateral is not shown for purposes of this presentation.

**Written Options** -In exchange for a premium, the fund wrote put options on securities for which it anticipated the price would increase. At the time the option was written, the fund believed the premium received exceeded the potential loss that could result from adverse price changes in the options' underlying securities. In a written option, the fund as the option writer grants the buyer the right to purchase from, or sell to, the fund a specified number of shares or units of a particular security, currency or index at a specified price within a specified period of time.

A written swaption represents an option that if exercised by the buyer, obligates the fund as option writer to enter into a pre-defined interest rate agreement with the counterparty at a specified rate at a specified date or within a specified period of time. The fund enters into swaptions primarily to preserve a return or spread on a particular investment or portion of the fund's investments, to adjust the fund's sensitivity to underlying risk factors or to protect against an increase or decrease in the price of securities.

The premium received is initially recorded as a liability in the Statement of Assets and Liabilities. The option is subsequently marked-to-market daily with the difference between the premium received and the market value of the written option being recorded as unrealized appreciation or depreciation. When a written option expires, the fund realizes a gain equal to the amount of the premium received. The difference between the premium received and the amount paid on effecting a closing transaction is considered a realized gain or loss. When a written call option is exercised, the premium received is offset against the proceeds to determine the realized gain or loss.

At the initiation of the written option contract, for exchange traded options, the fund is required to deposit securities or cash as collateral with the custodian for the benefit of the broker or directly with the clearing broker, based on the type of option. For uncleared options, the fund may post collateral subject to the terms of an ISDA Master Agreement as generally described above ifthe market value of the options contract moves against it. The fund, as writer of an option, may have no control over whether the underlying securities may be sold (call) or purchased (put) and, as a result, bears the market risk of an unfavorable change in the price of the securities underlying the written option. Losses from writing options can exceed the premium received and can exceed the potential loss from an ordinary buy and sell transaction. Although the fund's market risk may be significant, the maximum counterparty credit risk to the fund is equal to the market value of any collateral posted to the broker. For uncleared options, this risk is mitigated in cases where there is an ISDA Master Agreement between the fund and the counterparty providing for netting as described above.

**Purchased Options** — The fund purchased put options for a premium. Purchased put options entitle the holder to buy and sell a specified number of shares or units of a particular security, currency or index at a specified price at a specified date or within a specified period of time. Purchasing put options may hedge against an anticipated decline in the value of portfolio securities or currency or decrease the fund's exposure to an underlying instrument.

A purchased swaption represents an option that gives the fund as purchaser the right, but not the obligation, to enter into a pre-defined interest rate swap agreement with the counterparty at a specified rate at a specified date or within a specified period of time. The fund enters into swaptions primarily to preserve a return or spread on a particular investment or portion of the fund's investments, to adjust the fund's sensitivity to underlying risk factors or to protect against an increase or decrease in the price of securities.

The premium paid is initially recorded as an investment in the Statement of Assets and Liabilities. That investment is subsequently marked-to-market daily with the difference between the premium paid and the market value of the purchased option being recorded as unrealized appreciation or depreciation. Premiums paid for purchased call and put options which have expired are treated as realized losses on investments in the Statement of Operations. Upon the exercise or closing of a purchased call option, the premium paid is added to the cost of the security or financial instrument purchased. Upon the exercise or closing of a purchased put option, the premium paid is offset against the proceeds on the sale of the underlying security or financial instrument in order to determine the realized gain or loss on investments.

Whether or not the option is exercised, the fund's maximum risk of loss from purchasing an option is the amount of premium paid. All option contracts involve credit risk if the counterparty to the option contract fails to perform. For uncleared options, this risk is mitigated in cases where there is an ISDA Master Agreement between the fund and the counterparty providing for netting as described above and, where applicable, by the posting of collateral by the counterparty to the fund to cover the fund's exposure to the counterparty under such ISDA Master Agreement.

**Futures Contracts** — The fund entered into futures contracts which may be used to hedge against or obtain broad market exposure, interest rate exposure, currency exposure, or to manage duration. A futures contract represents a commitment for the future purchase or sale of an asset at a specified price on a specified date.

Upon entering into a futures contract, the fund is required to deposit with the broker, either in cash or securities, an initial margin in an amount equal to a specified percentage of the notional amount of the contract. Subsequent payments (variation margin) are made or received by the fund each day, depending on the daily fluctuations in the value of the contract, and are recorded for financial statement purposes as unrealized gain or loss by the fund until the contract is closed or expires at which point the gain or loss on futures contracts is realized.

The fund bears the risk of interest rates, exchange rates or securities prices moving unexpectedly, in which case, the fund may not achieve the anticipated benefits of the futures contracts and may realize a loss. While futures contracts may present less counterparty risk to the fund since the contracts are exchange traded and the exchange's clearinghouse guarantees payments to the broker, there is still counterparty credit risk due to the insolvency of the broker. The fund's maximum risk of loss due to counterparty credit risk is equal to the margin posted by the fund to the broker plus any gains or minus any losses on the outstanding futures contracts.

**Forward Foreign Currency Exchange Contracts** — The fund entered into forward foreign currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. These contracts may be used to hedge the fund's currency risk or for non-hedging purposes. For hedging purposes, the fund may enter into contracts to deliver or receive foreign currency that the fund will receive from or use in its normal investment activities. The fund may also use contracts to hedge against declines in the value of foreign currency denominated securities due to unfavorable exchange rate movements. For non-hedging purposes, the fund may enter into contracts with the intent of changing the relative exposure of the fund's portfolio of securities to different currencies to take advantage of anticipated exchange rate changes.

Forward foreign currency exchange contracts are adjusted by the daily exchange rate of the underlying currency and any unrealized gains or losses are recorded as a receivable or payable for forward foreign currency exchange contracts until the contract settlement date. On contract settlement date, any gain or loss on the contract is recorded as realized gains or losses on forward foreign currency exchange contracts.

Risks may arise upon entering into these contracts from unanticipated movements in the value of the contract and from the potential inability of counterparties to meet the terms of their contracts. Generally, the fund's maximum risk due to counterparty credit risk is the unrealized gain on the contract due to the use of Continuous Linked Settlement, a multicurrency cash settlement system for the centralized settlement of foreign transactions. This risk is mitigated in cases where there is an ISDA Master Agreement between the fund and the counterparty providing for netting as described above and, where applicable, by the posting of collateral by the counterparty to the fund to cover the fund's exposure to the counterparty under such ISDA Master Agreement.

**Swap Agreements** — The fund entered into swap agreements which generally involve a periodic exchange of cash payments on a net basis, at specified intervals or upon the occurrence of specified events, between the fund and a counterparty. Certain swap agreements may be entered into as a bilateral contract ("uncleared swaps") while others are required to be centrally cleared ("cleared swaps").

------

MFS Global Opportunistic Bond Fund

*Notes to Financial Statements - continued* 

Both cleared and uncleared swap agreements are marked to market daily. The value of uncleared swap agreements is reported in the Statement of Assets and Liabilities as "Uncleared swaps, at value" which includes any related interest accruals to be paid or received by the fund. For cleared swaps, payments (variation margin) are made or received by the fund each day, depending on the daily fluctuations in the value of the cleared swap, such that only the current day net receivable or payable for variation margin is reported in the Statement of Assets and Liabilities.

For both cleared and uncleared swaps, premiums paid or received at the inception of the agreements are amortized over the term of the agreement as realized gain or loss on swap agreements in the Statement of Operations. The periodic exchange of net cash payments, as well as any liquidation payment received or made upon early termination, are recorded as a realized gain or loss on swap agreements in the Statement of Operations. The change in unrealized appreciation or depreciation on swap agreements in the Statement of Operations reflects the aggregate change over the reporting period in the value of swaps net of any unamortized premiums paid or received.

Risks related to swap agreements include the possible lack of a liquid market, unfavorable market and interest rate movements of the underlying instrument and the failure of the counterparty to perform under the terms of the agreements. The fund's maximum risk of loss from counterparty credit risk is the discounted net value of the cash flows to be received from/paid to the counterparty over the contract's remaining life, to the extent that the amount is positive. To address counterparty risk, uncleared swap agreements are limited to only highly-rated counterparties. Risk is further reduced by having an ISDA Master Agreement ("ISDA") between the fund and the counterparty and, where applicable, by the posting of collateral by the counterparty to the fund to cover the fund's exposure to the counterparty under such ISDA. The fund's counterparty risk due to cleared swaps is mitigated by the fact that the clearinghouse is the counterparty to the transaction and the regulatory requirement safeguards in the event of a clearing broker bankruptcy.

The fund entered into interest rate swap agreements in order to manage its exposure to interest rate fluctuations. Interest rate swap agreements involve the periodic exchange of cash flows, between the fund and a counterparty, based on the difference between two interest rates applied to a notional principal amount. The two interest rates exchanged may either be a fixed rate and a floating rate or two floating rates based on different indices.

The fund entered into credit default swap agreements in order to manage its exposure to the market or certain sectors of the market, to reduce its credit risk exposure to defaults of corporate and sovereign issuers or to create exposure to corporate or sovereign issuers to which it is not otherwise exposed. A credit default swap's reference obligation may be either a single security or a basket of securities issued by corporate or sovereign issuers. At the inception of the agreement, the protection buyer may make an upfront payment to or receive an upfront payment from the protection seller. Over the term of the agreement, the protection buyer will make a series of periodic payments to the protection seller based on a fixed percentage applied to the agreement's notional amount in exchange for a promise from the protection seller to make a specific payment should a defined credit event occur with respect to the reference obligation. Although agreement-specific, credit events generally consist of a combination of the following: bankruptcy, failure to pay, restructuring, obligation acceleration, obligation default, or repudiation/moratorium. If a defined credit event occurs, the protection buyer will either (i) receive from the protection seller an amount equal to the agreement's notional amount and deliver the reference obligation (i.e., physical settlement) or (ii) receive from the protection seller a net settlement of cash equal to the agreement's notional amount less the recovery value of the reference obligation. Upon determination of the final price for the reference obligation (or upon delivery of the reference obligation in the case of physical settlement), the difference between the recovery value of the reference obligation and the agreement's notional amount is recorded as realized gain or loss on swap agreements in the Statement of Operations.

Credit default swap agreements are considered to have credit-risk-related contingent features since they trigger payment by the protection seller to the protection buyer upon the occurrence of a defined credit event. The maximum amount of future, undiscounted payments that the fund, as protection seller, could be required to make is equal to the swap agreement's notional amount. The protection seller's payment obligation would be offset to the extent of the value of the agreement's deliverable obligation. At November 30, 2025, the fund did not hold any credit default swap agreements at an unrealized loss where it is the protection seller. The fund's maximum risk of loss from counterparty risk, either as the protection seller or as the protection buyer, is the fair value of the agreement.

The fund entered into inflation swap agreements in order to manage its exposure to inflation risk. Inflation swap agreements involve the periodic exchange of cash flows, between the fund and a counterparty, based on the difference between two rates applied to a notional principal amount. The two rates exchanged are generally a fixed rate and a floating rate based on an inflation index.

**Mortgage-Backed/Asset-Backed Securities** — The fund invests a significant portion of its assets in asset-backed and/or mortgage-backed securities. For these securities, the value of the debt instrument also depends on the credit quality and adequacy of the underlying assets or collateral as well as whether there is a security interest in the underlying assets or collateral. Enforcing

MFS Global Opportunistic Bond Fund

*Notes to Financial Statements - continued* 

rights, if any, against the underlying assets or collateral may be difficult. U.S. Government securities not supported as to the payment of principal or interest by the U.S. Treasury, such as those issued by Fannie Mae, Freddie Mac, and the Federal Home Loan Banks, are subject to greater credit risk than are U.S. Government securities supported by the U.S. Treasury, such as those issued by Ginnie Mae.

**Indemnifications** — Under the fund's organizational documents, its officers and Trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the fund. Additionally, in the normal course of business, the fund enters into agreements with service providers that may contain indemnification clauses. The fund's maximum exposure under these agreements is unknown as this would involve future claims that may be made against the fund that have not yet occurred.

**Investment Transactions and Income** — Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. Interest payments received in additional securities are recorded on the ex-interest date in an amount equal to the value of the security on such date.

The fund may receive proceeds from litigation settlements. Any proceeds received from litigation involving portfolio holdings are reflected in the Statement of Operations in realized gain/loss if the security has been disposed of by the fund or in unrealized gain/loss if the security is still held by the fund. Any other proceeds from litigation not related to portfolio holdings are reflected as other income in the Statement of Operations.

Investment transactions are recorded on the trade date. In determining the net gain or loss on securities sold, the cost of securities is determined on the identified cost basis.

The fund may purchase or sell mortgage-backed securities on a To Be Announced ("TBA") basis. A TBA transaction is subject to extended settlement and typically does not designate the actual security to be delivered, but instead includes an approximate principal amount. The price of the TBA security and the date that it will be settled are fixed at the time the transaction is negotiated. The value of the security varies with market fluctuations and no interest accrues to the fund until settlement takes place. TBA purchase and sale commitments are held at carrying amount, which approximates fair value and are categorized as level 2 within the fair value hierarchy and included in TBA purchase and TBA sale commitments in the Statement of Assets and Liabilities, as applicable. Losses may arise as a result of changes in the value of the TBA investment prior to settlement date or due to counterparty non-performance.

The fund may also enter into mortgage dollar rolls, typically TBA dollar rolls, in which the fund sells TBA mortgage-backed securities to financial institutions and simultaneously agrees to repurchase similar (same issuer, type and coupon) securities at a later date at an agreed-upon price. During the period between the sale and repurchase, the fund will not be entitled to receive interest and principal payments on the securities sold. The fund accounts for dollar roll transactions as purchases and sales and realizes gains and losses on these transactions. As such, these transactions may result in an increase to the fund's portfolio turnover rate. Portfolio turnover rates including and excluding TBA transactions are presented in the Financial Highlights. Dollar roll transactions involve the risk that the market value of the securities that the fund is required to purchase may decline below the agreed upon repurchase price of those securities.

The fund may purchase or sell securities on a when-issued or delayed delivery basis. In these extended settlement transactions, the receipt or delivery of the securities by the fund and related payments occur at a future date, usually beyond the customary settlement period. The price of such security and the date that the security will be settled are generally fixed at the time the transaction is negotiated. The value of the security varies with market fluctuations and for debt securities no interest accrues to the fund until settlement takes place. When the fund sells securities on a when-issued or delayed delivery basis, the fund typically owns or has the right to acquire securities equivalent in kind and amount to the securities sold. Purchase and sale commitments for when-issued or delayed delivery securities are held at carrying amount, which approximates fair value and are categorized as level 2 within the fair value hierarchy, and included in When-issued investments purchased and When-issued investments sold in the Statement of Assets and Liabilities, as applicable. Losses may arise due to changes in the value of the underlying securities prior to settlement date or if the counterparty does not perform under the contract's terms, or if the issuer does not issue the securities.

To mitigate the counterparty credit risk on To Be Announced ("TBA") transactions, mortgage dollar rolls, and other types of forward settling mortgage-backed and asset-backed security transactions, the fund whenever possible enters into a Master Securities Forward Transaction Agreement ("MSFTA") on a bilateral basis with each of the counterparties with whom it undertakes a significant volume of transactions. The MSFTA gives each party to the agreement the right to terminate all transactions traded under such agreement if there is a specified deterioration in the credit quality of the other party. Upon an event of default or a termination of the MSFTA, the non-defaulting party has the right to close out all transactions traded under such agreement and to net amounts owed under each transaction to one net amount payable by one party to the other. This right to close out and net payments across all transactions traded under the MSFTA could result in a reduction of the fund's credit risk to such counterparty equal to any amounts payable by the fund under the applicable transactions, if any.

------

MFS Global Opportunistic Bond Fund

*Notes to Financial Statements - continued* 

For mortgage-backed and asset-backed securities traded under a MSFTA, the collateral and margining requirements are contract specific. Collateral amounts across all transactions traded under such agreement are netted and an amount is posted from one party to the other to collateralize such obligations. Cash that has been pledged to cover the fund's collateral or margin obligations under a MSFTA, if any, will be reported separately on the Statement of Assets and Liabilities as restricted cash. Securities pledged as collateral or margin for the same purpose, if any, are noted in the Portfolio of Investments.

**Fees Paid Indirectly** — The fund's custody fee may be reduced by a credit earned under an arrangement that measures the value of U.S. dollars deposited with the custodian by the fund. The amount of the credit, for the year ended November 30, 2025, is shown as a reduction of total expenses in the Statement of Operations.

**Tax Matters and Distributions** — The fund intends to qualify as a regulated investment company, as defined under Subchapter M of the Internal Revenue Code, and to distribute all of its taxable income, including realized capital gains. As a result, no provision for federal income tax is required. The fund's federal tax returns, when filed, will remain subject to examination by the Internal Revenue Service for generally a three year period. Management has analyzed the fund's tax positions taken on federal and state tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability. Foreign taxes, if any, have been accrued by the fund in the accompanying financial statements in accordance with the applicable foreign tax law. Foreign income taxes may be withheld by certain countries in which the fund invests. Additionally, capital gains realized by the fund on securities issued in or by certain foreign countries may be subject to capital gains tax imposed by those countries.

Distributions to shareholders are recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from U.S. generally accepted accounting principles. Certain capital accounts in the financial statements are periodically adjusted for permanent differences in order to reflect their tax character. These adjustments have no impact on net assets or net asset value per share. Temporary differences which arise from recognizing certain items of income, expense, gain or loss in different periods for financial statement and tax purposes will reverse at some time in the future.

Book/tax differences primarily relate to amortization of premium and accretion of discount of debt securities, wash sale loss deferrals, straddle loss deferrals, and derivative transactions.

The tax character of distributions declared to shareholders for the last two fiscal years is as follows:

---

| | | |
|:---|:---|:---|
|  | &nbsp;&nbsp; **Year ended** <br>**11/30/25**<br>| &nbsp;&nbsp; **Year ended** <br>**11/30/24**<br>|
| Ordinary income (including any short-term capital gains) | &nbsp;&nbsp; $36026513 | &nbsp;&nbsp; $34576252 |

The federal tax cost and the tax basis components of distributable earnings were as follows:

---

| | |
|:---|:---|
| **As of 11/30/25** |  |
| Cost of investments | &nbsp;&nbsp; $1031458287 |
| Gross appreciation | &nbsp;&nbsp; 20474595 |

| Other temporary differences | &nbsp;&nbsp; (3392876)<br>|
| Total distributable earnings (loss) | &nbsp;&nbsp; $(92014592)<br>|

---

As of November 30, 2025, the fund had capital loss carryforwards available to offset future realized gains. These net capital losses may be carried forward indefinitely and their character is retained as short-term and/or long-term losses. Such losses are characterized as follows:

---

| | |
|:---|:---|
| Short-Term | $(37495579)<br>|
| Long-Term | (83670301)<br>|
| Total | $(121165880)<br>|

**Multiple Classes of Shares of Beneficial Interest** — The fund offers multiple classes of shares, which differ in their respective distribution and service fees. The fund's income and common expenses are allocated to shareholders based on the value of settled shares outstanding of each class. The fund's realized and unrealized gain (loss) are allocated to shareholders based on the daily net assets of each class. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to

differences in separate class expenses. Class B and Class C shares will convert to Class A shares approximately eight years after purchase. The fund's distributions declared to shareholders as reported in the Statements of Changes in Net Assets are presented by class as follows:

---

| | | |
|:---|:---|:---|
|  | **Year ended** <br>**11/30/25**<br>| **Year ended** <br>**11/30/24**<br>|

**(3) Transactions with Affiliates**

**Investment Adviser** — The fund has an investment advisory agreement with MFS to provide overall investment management and related administrative services and facilities to the fund. The management fee is computed daily and paid monthly at the following annual rates based on the fund's average daily net assets:

---

| | |
|:---|:---|
| Up to $1 billion | 0.55% |
| In excess of $1 billion and up to $2.5 billion | 0.45% |
| In excess of $2.5 billion | 0.425% |

---

MFS has agreed in writing to reduce its management fee by a specified amount if certain MFS mutual fund assets exceed thresholds agreed to by MFS and the fund's Board of Trustees. MFS has also agreed in writing to waive at least 0.01% of its management fee as part of this agreement. The agreement to waive at least 0.01% of the management fee will continue until modified by the fund's Board of Trustees, but such agreement will continue at least until March 31, 2027. For the year ended November 30, 2025, this management fee reduction amounted to $140,662, which is included in the reduction of total expenses in the Statement of Operations. The management fee incurred for the year ended November 30, 2025 was equivalent to an annual effective rate of 0.53% of the fund's average daily net assets.

The investment adviser has agreed in writing to pay a portion of the fund's total annual operating expenses, excluding interest, taxes, extraordinary expenses, brokerage and transaction costs, certain tax reclaim recovery expenses (including contingency fees and closing agreement expenses), and investment-related expenses, such that total fund operating expenses do not exceed the following rates annually of each class's average daily net assets:

---

| | | | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|:---|:---|
|  |  |  |  | **Classes** |  |  |  |  |
| **A** | **B** | **C** | **I** | **R1** | **R2** | **R3** | **R4** | **R6** |
| 0.97% | 1.72% | 1.72% | 0.72% | 1.72% | 1.22% | 0.97% | 0.72% | 0.64% |

---

This written agreement will continue until modified by the fund's Board of Trustees, but such agreement will continue at least until March 31, 2027. For the year ended November 30, 2025, the fund's actual operating expenses did not exceed the limit and therefore, the investment adviser did not pay any portion of the fund's expenses related to this agreement.

**Distributor** — MFS Fund Distributors, Inc. (MFD), a wholly-owned subsidiary of MFS, as distributor, received $740 for the year ended November 30, 2025, as its portion of the initial sales charge on sales of Class A shares of the fund.

The Board of Trustees has adopted a distribution plan for certain share classes pursuant to Rule 12b-1 of the Investment Company Act of 1940.

The fund's distribution plan provides that the fund will pay MFD for services provided by MFD and financial intermediaries in connection with the distribution and servicing of certain share classes. One component of the plan is a distribution fee paid to MFD and another component of the plan is a service fee paid to MFD. MFD may subsequently pay all, or a portion, of the distribution and/or service fees to financial intermediaries. The distribution and service fees are computed daily and paid monthly.

(d) In accordance with the distribution plan for certain classes, the fund pays distribution and/or service fees equal to these annual percentage rates of each

class's average daily net assets. The distribution and service fee rates disclosed by class represent the current rates in effect at the end of the reporting

period. Any rate changes, if applicable, are detailed below.

(e) The annual effective rates represent actual fees incurred under the distribution plan for the year ended November 30, 2025 based on each class's average daily net assets. MFD has voluntarily agreed to rebate a portion of each class's 0.25% service fee attributable to accounts for which there is no financial intermediary specified on the account except for accounts attributable to MFS or its affiliates' seed money. For the year ended November 30, 2025, this rebate amounted to $22 for Class A shares and is included in the reduction of total expenses in the Statement of Operations.

Certain Class A shares are subject to a contingent deferred sales charge (CDSC) in the event of a shareholder redemption within 18 months of purchase. Class B shares are subject to a CDSC in the event of a shareholder redemption within six years of purchase. Class C shares are subject to a CDSC in the event of a shareholder redemption within 12 months of purchase. All contingent deferred sales charges are paid to MFD and during the year ended November 30, 2025, were as follows:

---

| | |
|:---|:---|
|  | **Amount** |
| Class A | $27753 |
| Class B |  |
| Class C | 47 |

**Shareholder Servicing Agent** — MFS Service Center, Inc. (MFSC), a wholly-owned subsidiary of MFS, receives a fee from the fund for its services as shareholder servicing agent calculated as a percentage of the average daily net assets of the fund as determined periodically under the supervision of the fund's Board of Trustees. For the year ended November 30, 2025, the fee was $17,616, which equated to 0.0017% annually of the fund's average daily net assets. MFSC also receives reimbursement from the fund for out-of-pocket expenses, sub-accounting and other shareholder servicing costs which may be paid to affiliated and unaffiliated service providers. Class R6 shares do not incur sub-accounting fees. For the year ended November 30, 2025, these out-of-pocket expenses, sub-accounting and other shareholder servicing costs amounted to $55,210.

**Administrator** — MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to the fund. Under an administrative services agreement, the fund reimburses MFS the costs incurred to provide these services. The fund is charged an annual fixed amount of $17,500 plus a fee based on average daily net assets. The administrative services fee is computed daily and paid monthly. The administrative services fee incurred for the year ended November 30, 2025 was equivalent to an annual effective rate of 0.0141% of the fund's average daily net assets.

**Trustees' and Officers' Compensation** — The fund pays compensation to independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons. Independent Trustees' compensation is accrued daily and paid subsequent to each Trustee Board meeting. The fund does not pay compensation directly to Trustees or officers of the fund who are also officers of the investment adviser, all of whom receive remuneration from MFS for their services to the fund. Certain officers and Trustees of the fund are officers or directors of MFS, MFD, and MFSC.

**Other** — The fund invests in the MFS Institutional Money Market Portfolio which is managed by MFS and seeks current income consistent with preservation of capital and liquidity. This money market fund does not pay a management fee to MFS but does incur investment and operating costs.

MFS purchased or redeemed fund shares on the dates indicated:

The fund is one of several mutual funds in which certain MFS funds may invest. The MFS funds do not invest in the underlying funds for the purpose of exercising management or control. At the end of the period, the MFS Moderate Allocation Fund, the MFS Conservative Allocation Fund, the MFS Growth Allocation Fund, the MFS Lifetime 2030 Fund, the MFS Lifetime Income Fund, the MFS Lifetime 2035 Fund, the MFS Lifetime 2025 Fund, and the MFS Lifetime 2040 Fund were the owners of record of approximately 31%, 25%, 19%, 5%, 4%, 3%, 2%, and 2%, respectively, of the value of outstanding voting shares of the fund. In addition, the MFS Lifetime 2045 Fund and the MFS Lifetime 2050 Fund were the owner of record of less than 1% of the value of outstanding voting shares of the fund.

Effective June 1, 2019, purchases of the fund's Class B shares were closed to new and existing investors subject to certain exceptions. Effective September 29, 2023, purchases of the fund's Class R1 and Class R2 shares were closed to new eligible investors.

**(6) Line of Credit**

The fund and certain other funds managed by MFS participate in a $1.45 billion unsecured committed line of credit of which $1.2 billion is reserved for use by the fund and certain other MFS U.S. funds. The line of credit is provided by a syndicate of banks under a credit agreement. Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, generally at a rate equal to the highest of 1) Daily Simple SOFR (Secured Overnight Financing Rate) plus 0.10%, 2) the Federal Funds Effective Rate, or 3) the Overnight Bank Funding Rate, each plus an agreed upon spread. A commitment fee, based on the average daily unused portion of the committed line of credit, is allocated among the participating funds. The line of credit expires on March 12, 2026 unless extended or renewed. In addition, the fund and other funds managed by MFS have established unsecured uncommitted borrowing arrangements with certain banks for temporary financing needs. Interest is charged to each fund, based on its borrowings, at rates equal to customary reference rates plus an agreed upon spread. For the year ended November 30, 2025, the fund's commitment fee and interest expense were $5,174 and $0, respectively, and are included in "Miscellaneous" expense in the Statement of Operations.

**(7) Investments in Affiliated Issuers**

An affiliated issuer may be considered one in which the fund owns 5% or more of the outstanding voting securities, or a company which is under common control. The following were affiliated issuers for the year ended November 30, 2025:

MFS Global Opportunistic Bond Fund

**Report of Independent Registered Public Accounting Firm**

To the Shareholders of MFS Global Opportunistic Bond Fund and the Board of Trustees of MFS Series Trust X

**Opinion on the Financial Statements**

We have audited the accompanying statement of assets and liabilities of MFS Global Opportunistic Bond Fund (the "Fund") (one of the funds constituting MFS Series Trust X (the "Trust")), including the portfolio of investments, as of November 30, 2025, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund (one of the funds constituting MFS Series Trust X) at November 30, 2025, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and its financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

**Basis for Opinion**

These financial statements are the responsibility of the Trust's management. Our responsibility is to express an opinion on the Fund's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Trust in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Trust is not required to have, nor were we engaged to perform, an audit of the Trust's internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of November 30, 2025, by correspondence with the custodian, brokers and others; when replies were not received from brokers and others, we performed other auditing procedures. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the auditor of one or more MFS investment companies since 1993.

**ITEM 11. STATEMENT REGARDING BASIS FOR APPROVAL OF INVESTMENT ADVISORY CONTRACT.**

------

MFS Global Opportunistic Bond Fund

**Board Review of Investment Advisory Agreement**

**MFS Global Opportunistic Bond Fund**

The Investment Company Act of 1940 requires that both the full Board of Trustees and a majority of the non-interested ("independent") Trustees, voting separately, annually approve the continuation of the Fund's investment advisory agreement with MFS. The Trustees consider matters bearing on the Fund and its advisory arrangements at their meetings throughout the year, including a review of performance data at each regular meeting. In addition, the independent Trustees met several times over the course of three months beginning in May and ending in July, 2025 ("contract review meetings") for the specific purpose of considering whether to approve the continuation of the investment advisory agreement for the Fund and the other investment companies that the Board oversees (the "MFS Funds"). The independent Trustees were assisted in their evaluation of the Fund's investment advisory agreement by independent legal counsel, from whom they received separate legal advice and with whom they met separately from MFS during various contract review meetings. The independent Trustees were also assisted in this process by an independent consultant who was retained by and reported to the independent Trustees.

In connection with their deliberations regarding the continuation of the investment advisory agreement, the Trustees, including the independent Trustees, considered such information and factors as they believed, in light of the legal advice furnished to them and their own business judgment, to be relevant. The investment advisory agreement for the Fund was considered separately, although the Trustees also took into account the common interests of all MFS Funds in their review. As described below, the Trustees considered the nature, quality, and extent of the various investment advisory, administrative, and shareholder services performed by MFS under the existing investment advisory agreement and other arrangements with the Fund.

In connection with their contract review meetings, the Trustees received and relied upon materials that included, among other items: (i) information provided by Broadridge Financial Solutions, Inc. ("Broadridge"), an independent third party, on the investment performance of the Fund for various time periods ended December 31, 2024 and the investment performance of a group of funds with substantially similar investment classifications/objectives (the "Broadridge performance universe"), (ii) information provided by Broadridge on the Fund's advisory fees and other expenses and the advisory fees and other expenses of comparable funds identified by Broadridge as well as all other funds in the same investment classification/category (the "Broadridge expense group and universe"), (iii) information provided by MFS on the advisory fees of portfolios of other clients of MFS, including institutional separate accounts and other clients, (iv) information as to whether and to what extent applicable expense waivers, reimbursements or fee "breakpoints" are observed for the Fund, (v) information regarding MFS' financial results and financial condition, including MFS' and certain of its affiliates' estimated profitability from services performed for the Fund and the MFS Funds as a whole, and compared to MFS' institutional business, (vi) MFS' views regarding the outlook for the mutual fund industry and the strategic business plans of MFS, (vii) descriptions of various functions performed by MFS for the Funds, such as compliance monitoring and portfolio trading practices, and (viii) information regarding the overall organization of MFS, including information about MFS' senior management and other personnel providing investment advisory, administrative and other services to the Fund and the other MFS Funds. The comparative performance, fee and expense information prepared and provided by Broadridge was not independently verified and the independent Trustees did not independently verify any information provided to them by MFS.

The Trustees' conclusion as to the continuation of the investment advisory agreement was based on a comprehensive consideration of all information provided to the Trustees and not the result of any single factor. Some of the factors that figured particularly in the Trustees' deliberations are described below, although individual Trustees may have evaluated the information presented differently from one another, giving different weights to various factors. It is also important to recognize that the fee arrangements for the Fund and other MFS Funds are the result of years of review and discussion between the independent Trustees and MFS, that certain aspects of such arrangements may receive greater scrutiny in some years than in others, and that the Trustees' conclusions may be based, in part, on their consideration of these same arrangements during the course of the year and in prior years.

Based on information provided by Broadridge and MFS, the Trustees reviewed the Fund's total return investment performance as well as the Broadridge performance universe over various time periods. The Trustees placed particular emphasis on the total return performance of the Fund's Class I shares in comparison to the performance of funds in its Broadridge performance universe over the five-year period ended December 31, 2024, which the Trustees believed was a long enough period to reflect differing market conditions. The total return performance of the Fund's Class I shares was in the 1st quintile relative to the other funds in the universe for this five-year period (the 1st quintile being the best performers and the 5th quintile being the worst performers). The total return performance of the Fund's Class I shares was in the 4th quintile for the one-year period and the 2nd quintile for the three-year period ended December 31, 2024 relative to the Broadridge performance universe. Because of the passage of time, these performance results may differ from the performance results for more recent periods, including those shown elsewhere in this report.

*Board Review of Investment Advisory Agreement - continued*

In the course of their deliberations, the Trustees took into account information provided by MFS in connection with the contract review meetings, as well as during investment review meetings conducted with portfolio management personnel during the course of the year regarding the Fund's performance. After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding the investment advisory agreement, that they were satisfied with MFS' responses and efforts relating to investment performance.

In assessing the reasonableness of the Fund's advisory fee, the Trustees considered, among other information, the Fund's advisory fee and the total expense ratio of the Fund's Class I shares as a percentage of average daily net assets and the advisory fee and total expense ratios of the Broadridge expense group based on information provided by Broadridge. The Trustees considered that MFS currently observes an expense limitation for the Fund, which may not be changed without the Trustees' approval. The Trustees also considered that, according to the data provided by Broadridge (which takes into account any fee reductions or expense limitations that were in effect during the Fund's last fiscal year), the Fund's effective advisory fee rate and total expense ratio were each higher than the Broadridge expense group median.

The Trustees also considered the advisory fees charged by MFS to any institutional separate accounts advised by MFS ("separate accounts") and unaffiliated investment companies for which MFS serves as subadviser ("subadvised funds") that have comparable investment strategies to the Fund, if any. In comparing these fees, the Trustees considered information provided by MFS as to the generally broader scope of services provided by MFS to the Fund, as well as the more extensive regulatory burdens imposed on MFS in managing the Fund, in comparison to separate accounts and subadvised funds. The Trustees also considered the higher demands placed on MFS' investment personnel and trading infrastructure as a result of the daily cash in-flows and out-flows of the Fund in comparison to separate accounts.

The Trustees also considered whether the Fund may benefit from any economies of scale in the management of the Fund in the event of growth in assets of the Fund and/or growth in assets of the MFS Funds as a whole. They noted that the Fund's advisory fee rate schedule is subject to a contractual breakpoint that reduces the Fund's advisory fee rate on average daily net assets over $1 billion and $2.5 billion. The Trustees also noted that MFS has agreed in writing to waive a portion of the management fees of certain MFS Funds, including the Fund, if the total combined assets of certain funds within the MFS Funds' complex increase above agreed upon thresholds (the "group fee waiver"), enabling the Fund's shareholders to share in the benefits from any economies of scale at the complex level. The group fee waiver is reviewed and renewed annually between the Board and MFS. The Trustees concluded that the breakpoints and the group fee waiver were sufficient to allow the Fund to benefit from economies of scale as its assets and overall complex assets grow.

The Trustees also considered information prepared by MFS relating to MFS' costs and profits with respect to the Fund, the MFS Funds considered as a group, and other investment companies and accounts advised by MFS, as well as MFS' methodologies used to determine and allocate its costs to the MFS Funds, the Fund and other accounts and products for purposes of estimating profitability.

After reviewing these and other factors described herein, the Trustees concluded, within the context of their overall conclusions regarding the investment advisory agreement, that the advisory fees charged to the Fund represent reasonable compensation in light of the services being provided by MFS to the Fund.

In addition, the Trustees considered MFS' resources and related efforts to continue to retain, attract and motivate capable personnel to serve the Fund. The Trustees also considered current and developing conditions in the financial services industry, including the presence of large and well-capitalized companies which are spending, and appear to be prepared to continue to spend, substantial sums to engage personnel and to provide services to competing investment companies. In this regard, the Trustees also considered the financial resources of MFS and its ultimate parent, Sun Life Financial Inc. The Trustees also considered the advantages and possible disadvantages to the Fund of having an adviser that also serves other investment companies as well as other accounts.

The Trustees also considered the nature, quality, cost, and extent of administrative, transfer agency, and distribution services provided to the Fund by MFS and its affiliates under agreements and plans other than the investment advisory agreement, including any 12b-1 fees the Fund pays to MFS Fund Distributors, Inc., an affiliate of MFS. The Trustees also considered the nature, extent and quality of certain other services MFS performs or arranges for on the Fund's behalf, which may include securities lending programs, directed expense payment programs, class action recovery programs, and MFS' interaction with third-party service providers, principally custodians and sub-custodians. The Trustees concluded that the various non-advisory services provided by MFS and its affiliates on behalf of the Fund were satisfactory.

The Trustees considered so-called "fall-out benefits" to MFS such as reputational value derived from serving as investment manager to the MFS Funds. The Trustees also considered that MFS discontinued its historic practice of obtaining investment research from portfolio brokerage commissions paid by certain MFS Funds effective January 2018, and directly pays or voluntarily reimburses a Fund, if applicable, for the costs of external research acquired through the use of the Fund's portfolio brokerage commissions.

MFS Global Opportunistic Bond Fund

*Board Review of Investment Advisory Agreement - continued*

Based on their evaluation of factors that they deemed to be material, including those factors described above, the Board of Trustees, including the independent Trustees, concluded that the Fund's investment advisory agreement with MFS should be continued for an additional one-year period, commencing August 1, 2025.

**Code of Ethics for Principal Executive and Principal Financial Officers**

**Effective April 1, 2024**

**Policy Purpose and Summary**

Section 406 of the Sarbanes-Oxley Act requires that each MFS Fund registered under the Investment Company Act of 1940 disclose whether or not it has adopted a code of ethics for senior financial officers, applicable to its principal financial officer and principal accounting officer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**I.Overview**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Covered Officers/Purpose of the Code

This code of ethics (this "Code") has been adopted by the funds (collectively, "Funds" and each, "Fund") under supervision of the MFS Funds Board (the "Board") and applies to the Funds' Principal Executive Officer and Principal Financial Officer (the "Covered Officers" each of whom is set forth in Exhibit A) for the purpose of promoting:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•full, fair, accurate, timely and understandable disclosure in reports and documents that the Funds file with, or submit to, the Securities and Exchange Commission ("SEC") and in other public communications made by the Funds;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•compliance by the Funds with applicable laws and governmental rules and regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the prompt internal reporting of violations of the Code to an appropriate person or persons identified in the Code; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•accountability for adherence to the Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Conduct Guidelines

Each Covered Officer should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest. In addition, each Covered Officer should not place his or her personal interests ahead of the Funds' interests and should endeavor to act honestly and ethically. In furtherance of the foregoing, each Covered Officer must:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•not use his or her personal influence or personal relationships improperly to influence investment decisions or financial reporting for any Fund whereby the Covered Officer would benefit personally to the detriment of the Fund; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•not cause a Fund to take action, or fail to take action, for the individual personal benefit of the Covered Officer rather than the benefit of the Fund.

The following activities, which could create the appearance of a conflict of interest, are permitted only with the approval of the Funds' Chief Legal Officer ("CLO"):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•service as a director on the board of any "for profit" company other than the board of the Funds' investment adviser or its subsidiaries or board of a pooled investment vehicle sponsored by the Funds' investment adviser or its subsidiaries;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•running for political office;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the receipt of any Fund business-related gift or any entertainment from any company with which a Fund has current or prospective business dealings unless such gift or entertainment is permitted by the gifts and entertainment policy of the Funds' investment adviser;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•any material ownership interest in, or any consulting or employment relationship with, any Fund service providers (e.g., custodian banks, audit firms), other than the Funds' investment adviser, principal underwriter, administrator or any affiliated person thereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a direct or indirect financial interest in commissions, transaction charges or spreads paid by a Fund for effecting portfolio transactions or for selling or redeeming shares, other than an interest arising from the Covered Officer's employment or securities ownership.

**C.Disclosure and Compliance**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Each Covered Officer should familiarize himself or herself with the disclosure requirements generally applicable to the Funds;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•each Covered Officer should not knowingly misrepresent, or cause others to misrepresent, facts about a Fund to others, whether within or outside the Fund, including to the Fund's trustees and auditors, and to governmental regulators and self-regulatory organizations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•each Covered Officer should, to the extent appropriate within his or her area of Fund responsibility, consult with other officers and employees of the Funds and the adviser with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Funds file with, or submit to, the SEC and in other public communications made by the Funds; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•it is the responsibility of each Covered Officer to promote compliance within his or her area of Fund responsibility with the standards and restrictions imposed by applicable laws, rules and regulations.

**D.Reporting and Accountability**

Each Covered Officer must:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•upon adoption of the Code (or thereafter as applicable, upon becoming a Covered Officer), affirm in writing to the Board that he or she has received, read, and understands the Code;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•annually thereafter affirm to the Board that he or she has complied with the requirements of the Code;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•annually report to the CLO affiliations and relationships which are or may raise the appearance of a conflict of interest with the Covered Officer's duties to the Funds, as identified in the annual Trustee and Officer Questionnaire;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•not retaliate against any other Covered Officer or any officer or employee of the Funds or their affiliated persons for reports of potential violations that are made in good faith; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•notify the CLO promptly if he or she knows of any violation of this Code. Failure to do so is itself a violation of this Code.

The CLO is responsible for applying this Code to specific situations in which questions are presented under it, granting waivers upon consultation with the Board or its designee, investigating violations, and has the authority to interpret this Code in any particular situation. The CLO will report requests for waivers to the Board (or a designee thereof) promptly upon receipt of a waiver request and will periodically report to the Board any approvals granted since the last report.

The CLO will take all appropriate action to investigate any potential violations reported to him or her and to report any violations to the Board. If the Board concurs that a violation has occurred, it will consider appropriate action, which may include review of, and appropriate modifications to, applicable policies and procedures; notification to appropriate personnel of the investment adviser or its board; or a recommendation to dismiss the Covered Officer.

Any changes to or waivers of this Code will, to the extent required, be disclosed as provided by SEC rules.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. Confidentiality

All reports and records prepared or maintained pursuant to this Code and under the direction of the CLO will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code, such matters shall not be disclosed to anyone other than the Funds' Board, its counsel, counsel to the Board's independent trustees and senior management and the board of directors of the Fund's investment adviser and its counsel.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. Internal Use

The Code is intended solely for the internal use by the Funds and does not constitute an admission, by or on behalf of any Fund, as to any fact, circumstance, or legal conclusion.

**II.Supervision**

The Board of Trustees of the Funds, including a majority of the Trustees who are not "interested persons" (as defined in the 1940 Act) of the Funds, shall review no less frequently than annually, a report from the CLO regarding the affirmations of the principal executive officer and the principal financial officer as to compliance with this Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**III.Interpretation and Escalation**

Breaches of the Code are reviewed by the CLO and communicated to the Board of Trustees of the affected Fund(s). Interpretations of this Policy shall be made from time to time by the CLO, as needed, and questions regarding the application of this Policy to a specific set of facts are escalated to the CLO.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;IV. Authority

Section 406 of the Sarbanes-Oxley Act.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**V.Monitoring**

Adherence to this policy is monitored by the CLO.

|:---|:---|
| VI. | **Related Policies** |
|  | This Code shall be the sole code of ethics adopted by the Funds for purposes of |
|  | Section 406 of the Sarbanes-Oxley Act and the rules and forms applicable to |
|  | registered investment companies thereunder. Insofar as other policies or procedures |
|  | of the Funds, the Funds' adviser, principal underwriter, or other service providers |
|  | govern or purport to govern the behavior or activities of the Covered Officers who |
|  | are subject to this Code, they are superseded by this Code to the extent that they |
|  | overlap or conflict with the provisions of this Code. The Funds' and their investment |
|  | adviser's codes of ethics under Rule 17j-1 under the Investment Company Act and |
|  | any other codes or policies or procedures adopted by the Funds or their investment |
|  | adviser or other service providers are separate requirements and are not part of this |
|  | Code. |
| VII. | **Amendment** |
|  | Any amendments to this Code, other than amendments to Exhibit A, must be |
|  | approved or ratified by a majority vote of the Board, including a majority of |
|  | independent trustees. |
| VIII. | **Recordkeeping** |
|  | All required books, records and other documentation shall be retained in accordance |
|  | with MFS' related record retention policy. |

---

**Additional procedures may need to be implemented by departments to properly comply with this policy.**
