#### ITEM 1 — ELECTION OF TRUSTEES
The Board of Trustees (the "Board"), which oversees each Trust, provides broad supervision over the affairs of each Trust. Those Trustees who are not "interested persons" (as defined in the Investment Company Act of 1940, as amended (the "1940 Act")) of your Trust or of MFS are referred to as "Independent Trustees" throughout this Proxy Statement. MFS is responsible for the investment management of each Trust's assets and for providing a variety of other administrative services to each Trust. The officers of each Trust are responsible for its operations.

The Board currently consists of 12 Trustees, 11 of whom are Independent Trustees. An Independent Trustee serves as Chair of the Board. Taking into account the number, the diversity, and the complexity of the MFS Funds (as defined below) overseen by the Board and the aggregate amount of assets under management in the Trusts, the Board has determined that the efficient conduct of its affairs makes it desirable to delegate responsibility for certain specific matters to Committees of the Board. Each of the seven standing Committees of the Board, to which the Board has delegated certain authority and oversight responsibilities, consists exclusively of Independent Trustees. In connection with each of the Board's regular meetings, the Independent Trustees meet separately from MFS with their counsel. The Independent Trustees also meet regularly with the Trusts' Chief Compliance Officer (who is also MFS' Chief Compliance Officer) to receive reports regarding the compliance of the Trusts with the federal securities laws and the Trusts' compliance policies and procedures. The Board reviews its leadership structure periodically and believes that its structure is appropriate to enable the Board to exercise its oversight of the Trusts.

------

The Trusts have retained MFS as their investment adviser and administrator. MFS provides the Trusts with investment advisory services, and is responsible for day-to-day administration of the Trusts and management of the risks that arise from the Trusts' investments and operations. Certain employees of MFS serve as the Trusts' officers, including the Trusts' principal executive officer and principal financial and accounting officer. The Board provides oversight of the services provided by MFS and its affiliates, including the risk management activities of MFS and its affiliates (including those related to cybersecurity). In addition, each Committee of the Board provides oversight of its risk management activities with respect to the particular activities within the Committee's purview. In the course of providing oversight, the Board and the Committees receive a wide range of reports on the Trusts' activities, including reports on each Trust's investment portfolio, the compliance of the Trusts with applicable laws, and the Trusts' financial accounting and reporting. The Board also meets periodically with the portfolio managers of each Trust to receive reports regarding the management of each Trust, including its investment risks. The Board and the relevant Committees meet periodically with MFS' Global Head of Enterprise Risk to receive reports on MFS' and its affiliates' risk management activities, including their efforts to (i) identify key risks that could adversely affect the Trusts or MFS; (ii) implement processes and controls to mitigate such key risks; and (iii) monitor business and market conditions in order to facilitate the processes described in (i) and (ii) above. In addition, the Board and the relevant Committees oversee risk management activities related to the key risks associated with services provided by various non-affiliated service providers through the receipt of reports prepared by MFS, and, in certain circumstances, through the receipt of reports directly from service providers, such as in the case of each Trust's auditor and custodian. As the Trusts' operations are carried out by service providers, the Board's oversight of the risk management processes of the service providers, including processes to address cybersecurity and other operational failures, is inherently limited.

Effective as of the election and qualification of the nominees at the 2025 Annual Meeting of Shareholders, the Board has fixed the number of Trustees of each Trust at 12. Under the provisions of each Trust's Declaration of Trust, the Trustees are divided into three classes, each having a term of three years.<sup>1</sup> Under the terms of the Board's retirement policy, an Independent Trustee shall retire at the end of the calendar year in which he or she reaches the earlier of 75 years of age or 15 years of service on the Board (or, in the case of an Independent Trustee who joined the Board prior to 2015, 20 years of service on the Board). Laurie J. Thomsen will reach 20 years of service in 2025 and is expected to retire effective December 31, 2025, pursuant to the Board's retirement policy.

For each of MFS Charter Income Trust, MFS Government Markets Income Trust, MFS Intermediate High Income Fund, MFS Intermediate Income Trust, and MFS Multimarket Income Trust, the Nomination and Compensation Committee has selected and nominated, and recommended that the Board nominate, for election by common shareholders, Maureen R. Goldfarb, Maryanne L. Roepke, Paula E. Smith, and Laurie J. Thomsen, as Trustees of the class whose term will expire at the 2028 Annual Meeting of Shareholders (or special meeting in lieu thereof) of the Trust, in each case, to hold office until his or her successor is elected and qualified, with the exception of Ms. Thomsen, who is expected to retire from the Board effective December 31, 2025, pursuant to the Board's retirement policy. The Board has nominated each of the individuals selected and nominated by the Committee. Each nominee is presently a Trustee of MFS Charter Income Trust, MFS Government Markets Income Trust, MFS Intermediate High Income Fund, MFS Intermediate Income Trust, and MFS Multimarket Income Trust, and has agreed to serve as a Trustee of each Trust if elected. The Board recommends that you vote in favor of their election.

For each of MFS High Income Municipal Trust, MFS High Yield Municipal Trust, MFS Investment Grade Municipal Trust, and MFS Municipal Income Trust, the Nomination and Compensation Committee has selected and nominated, and recommended that the Board nominate, for election by common and preferred shareholders, voting together as a single class, Maureen R. Goldfarb, Paula E. Smith, and Laurie J. Thomsen, as Trustees of the class whose term will expire at the 2028 Annual Meeting of Shareholders (or special meeting in lieu thereof) to hold office until his or her successor is elected and qualified, with the exception of Ms. Thomsen, who is expected to retire from the Board effective December 31, 2025, pursuant to the Board's retirement policy. The Nomination and Compensation Committee has also selected and nominated, and recommended that the Board nominate, for election by preferred shareholders only, voting as a separate class, John P. Kavanaugh and Maryanne L. Roepke, for a term that will expire at the next annual Meeting of shareholders (or special meeting in lieu thereof) to hold office until his or her successor is elected and qualified. The Board has nominated each of the individuals selected and nominated by the Committee. Each nominee is presently a Trustee of MFS High Income Municipal Trust, MFS High Yield Municipal Trust, MFS Investment Grade Municipal Trust, and MFS Municipal Income Trust and has agreed to serve as Trustee of each Trust if elected. The Board recommends that you vote in favor of their election.

It is intended that, absent contrary instructions, proxies will be voted in favor of electing Maureen R. Goldfarb, John P. Kavanaugh, Maryanne L. Roepke, Paula E. Smith, and Laurie J. Thomsen. If, before the election, any nominee refuses or is unable to serve, proxies will be voted for a replacement nominee designated by each Trust's current Trustees, or the Trustees may fix the number of Trustees at fewer than 12 for a Trust.

<sup>1</sup> For MFS High Income Municipal Trust, MFS High Yield Municipal Trust, MFS Investment Grade Municipal Trust, and MFS Municipal Income Trust, two Trustees are solely elected by the holders of the preferred shares of each Trust for a one-year term.

------

The Trustees of the Trusts as of August 1, 2025, are listed below, together with their principal occupations during the past five years (their titles may have varied during that period). Additional information about each Trustee follows the table.

<sup>(1)</sup> Date first appointed to serve as Trustee of an MFS Fund. Each Trustee has served continuously since appointment unless indicated otherwise.

<sup>(2)</sup> An Independent Trustee shall retire at the end of the calendar year in which he or she reaches the earlier of 75 years of age or 15 years or service on the Board (or, in the case of any Independent Trustee who joined the Board prior to 2015, 20 years of service on the Board).

<sup>(3)</sup> Directorships or trusteeships of companies required to report to the Securities and Exchange Commission (the "SEC") (i.e., "public companies").

<sup>(4)</sup> "Interested person" of the Trust within the meaning of the 1940 Act, which is the principal federal law governing investment companies like the Trusts, as a result of holding a position with MFS. The address of MFS is 111 Huntington Avenue, Boston, Massachusetts 02199.

<sup>(5)</sup> For each of MFS High Income Municipal Trust, MFS High Yield Municipal Trust, MFS Investment Grade Municipal Trust, and MFS Municipal Income Trust, Mr. Kavanaugh and Ms. Roepke serve as Trustees elected by the holders of preferred shares for a one-year term.

<sup>(6)</sup> For each of MFS Charter Income Trust, MFS Government Markets Income Trust, MFS Intermediate High Income Fund, MFS Intermediate Income Trust, and MFS Multimarket Income Trust, Mr. Kavanaugh and Ms. Roepke serve as Trustees elected by holders of common shares for a three-year term.

Unless otherwise noted, each current Trustee listed above served as a member of the Board of 139 funds within the MFS Family of Funds (the "MFS Funds") as of July 31, 2025. The address of each Trustee is c/o MFS, 111 Huntington Avenue, Boston, Massachusetts 02199.

The following provides an overview of the Board's process for identifying individuals for the pool from which trustee candidates are ultimately selected and the considerations that led the Board to conclude that each individual serving as a Trustee of the Trust should so serve. As part of this process, the Board works with the Nomination and Compensation Committee, which recommends qualified trustee candidates to the Board in the event that a position is vacated or created. Because the Trustees believe that a well-balanced and qualified board is an important component of a strong governance structure, the Board is committed to actively seeking individuals with diverse backgrounds, experience and perspectives, including women and underrepresented minority candidates, for the pool from which trustee candidates are selected. The current members of the Board have joined the Board at different points in time since 2005. Generally, no one factor was decisive in the original selection of an individual to join the Board. Among the factors the Board considered when concluding that an individual should serve on the Board were the following: (i) the individual's business and professional experience and accomplishments; (ii) the individual's ability to work effectively with the other members of the Board; (iii) the individual's prior experience, if any, serving on the boards of public companies (including, where relevant, other investment companies) and other complex enterprises and organizations; and (iv) how the individual's skills, experience and attributes would contribute to an appropriate mix of relevant skills, experience, and perspectives on the Board.

------

In respect of each current Trustee, the individual's substantial professional accomplishments and prior experience, including, in some cases, in fields related to the operations of the Trusts, were a significant factor in the determination that the individual should serve as a Trustee of the Trusts.

During the fiscal years ended October 31, 2024 and November 30, 2024, each Trust held six Board meetings. Each Trustee attended at least 75% of the Board and applicable committee meetings noted for each Trust.

#### Audit Committee
Each Trust's Audit Committee consists only of Independent Trustees. Each Trust's Audit Committee's statement on the Trust's most recent audited financials is included below under the heading "Independent Registered Public Accounting Firm." Each Trust's Board has adopted a written charter for the Audit Committee. A copy of the Audit Committee's charter is available at www.mfs.com. To access a copy of the Audit Committee's charter, after entering the website by entering "United States" as your location and entering "Individual Investor" as your role if you have not already done so, hover your cursor over "Products & Strategies," and then click on "Closed End Funds" under the "Investment Options" heading. Next, use the drop-down menu and click on the Trust name, then click on the "Resources" tab, then click on the "Reports & Other Documents" tab, and then click on "Audit Committee Charter."

#### Nomination and Compensation Committee
The Trustees have adopted a written charter for the Nomination and Compensation Committee. A copy of the Nomination and Compensation Committee's charter is available at www.mfs.com. To access a copy of the Nomination and Compensation Committee's charter, after entering the website by entering "United States" as your location and entering "Individual Investor" as your role if you have not already done so, hover your cursor over "Products & Strategies," and then click on "Closed End Funds" under the "Investment Options" heading. Next, use the drop-down menu and click on the Trust name, then click on the "Resources" tab, then click on the "Reports & Other Documents" tab, and then click on "Nomination and Compensation Committee Charter."

Each Trust's Nomination and Compensation Committee consists only of Independent Trustees.

------

The Nomination and Compensation Committee requires that Trustee candidates have a college degree or equivalent business experience, but has not otherwise established specific, minimum qualifications that must be met by an individual to be considered by the Committee for nomination as a Trustee. The Nomination and Compensation Committee may take into account a wide variety of factors in considering Trustee candidates, including, but not limited to: (i) availability and commitment of a candidate to attend meetings and perform his or her responsibilities to the Board; (ii) relevant industry and related experience; (iii) educational background; (iv) financial expertise; (v) an assessment of the candidate's ability, judgment and expertise; (vi) overall diversity of the composition of the Board; and (vii) such other factors as the Committee deems appropriate. While the Committee has not adopted a particular definition of diversity, when considering a nominee's and the Board's diversity, the Committee generally considers the manner in which each nominee's professional experience, expertise in matters that are relevant to the oversight of the Trust (e.g., investment management, distribution, accounting, trading, compliance, legal), general leadership experience, and life experience (including with respect to gender and ethnicity) are complementary and, as a whole, contribute to the ability of the Board to oversee the Trust. The Nomination and Compensation Committee may consider candidates for Trustee recommended by each Trust's current Trustees, officers or shareholders or by MFS or any other source deemed appropriate by the Nomination and Compensation Committee. The Nomination and Compensation Committee may, but is not required to, retain a third-party search firm at the applicable Trust's expense to identify potential candidates.

The Nomination and Compensation Committee will review and consider nominees recommended by shareholders to serve as Trustee, provided that the recommending shareholder follows the Procedures for Shareholders to Submit Nominee Candidates, which are set forth as Appendix B to the Trusts' Nomination and Compensation Committee Charter (which is available at www.mfs.com). Among other requirements, these procedures provide that the recommending shareholder must submit any recommendation in writing to the Trust, to the attention of the Trust's Secretary, at the address of the principal executive offices of the Trust. Any recommendation must include certain biographical information and other information regarding the candidate and the recommending shareholder, and must include a written and signed consent of the candidate to be named as a nominee and to serve as a Trustee if elected. The Nomination and Compensation Committee takes the diversity of a particular nominee and the overall diversity of the Board into account when considering and evaluating nominees for trustee. The foregoing description is only a summary.

The Nomination and Compensation Committee has full discretion to reject nominees recommended by shareholders, and there is no assurance that any such person properly recommended and considered by the Committee will be nominated for election to the Board of a Trust.

#### Share Ownership
As of July 31, 2025, the Trustees and Officers of each Trust as a group owned less than 1% of the outstanding shares of any Trust. The Board has adopted a policy requiring that each Independent Trustee shall have invested on an aggregate basis, within two years of membership on the Board, an amount equal to his or her prior calendar year's base retainer and meeting attendance fees in shares of the MFS Funds.

The following table shows the dollar range of equity securities beneficially owned by each nominee or Trustee (a) of each Trust and (b) on an aggregate basis, in the MFS Funds overseen by the nominee or Trustee, as of July 31, 2025.

#### Shareholder Communications with the Board of Trustees
The Board of Trustees of each Trust has adopted procedures by which shareholders may send communications to the Board. Shareholders may mail written communications to the Board of Trustees, [Name of Trust], Massachusetts Financial Services Company, 111 Huntington Avenue, Boston, Massachusetts 02199, Attention: Secretary of the Trust. Shareholder communications must (i) be in writing and be signed by the shareholder, (ii) identify the Trust to which they relate and (iii) identify the class and number of shares held by the shareholder. The Secretary is responsible for reviewing all properly submitted shareholder communications. The Secretary shall either (i) provide a copy of each properly submitted shareholder communication to the Board at its next regularly scheduled meeting or (ii) if the Secretary determines that the communication requires more immediate attention, forward the communication to the Chair of the Board promptly after receipt. The Secretary may, in good faith, determine that a shareholder communication should not be provided to the Board because it is ministerial in nature (such as a request for Trust literature, share data or financial information). The Secretary may in such cases forward the communication to the appropriate party or parties at MFS. These procedures do not apply to (i) any communication from an officer or Trustee of the Trust, (ii) any communication from an employee or agent of the Trust, unless such communication is made solely in such employee's or agent's capacity as a shareholder or (iii) any shareholder proposal submitted pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, as amended, or any communication made in connection with such a proposal. Each Trust's Trustees are not required to attend the Trust's shareholder Meetings or to otherwise make themselves available to shareholders for communications, other than pursuant to the aforementioned procedures. The Trustees did not attend the 2024 Annual Meeting of Shareholders.

Each Trust's Declaration of Trust currently provides that the Trust will indemnify its Trustees and Officers against liabilities and expenses incurred in connection with litigation in which they may be involved because of their offices with the Trust, unless it is finally adjudicated or, in case of a settlement, it has been determined by Trustees not involved in the matter or independent legal counsel, that they have not acted in good faith in the reasonable belief that their actions were in the best interests of the Trust or that they engaged in willful misfeasance or acted with bad faith, gross negligence or reckless disregard of the duties involved in the conduct of their offices.

#### Trustee Compensation Table
The table below shows the cash compensation paid to the Trustees by each Trust during the fiscal year ended on the date noted (see footnote 1). Interested Trustee(s) receives no compensation from any Trust for their services as Trustee(s).

The Independent Registered Public Accounting Firm has no direct or material indirect interest in a Trust.

Representatives of the applicable Independent Registered Public Accounting Firm are not expected to be present at the Meeting, but they will have the opportunity to make a statement if they wish, and they will be available should any matter arise requiring their presence.

Each Trust's Audit Committee submitted the following statement to be included in this Proxy Statement:

The Audit Committee reviewed and discussed the audited financial statements with Trust management. The Audit Committee also discussed with the independent public accounting firm the matters required to be discussed by the applicable requirements of the PCAOB and the Securities and Exchange Commission ("SEC"). The Audit Committee received the written disclosures and the letter from the independent public accounting firm required by the PCAOB regarding the independent public accounting firm's communications with the Audit Committee regarding independence, and discussed with the independent public accounting firm its independence.

Based on this review and the review of other information and these and other discussions, the Audit Committee recommended to the Board of Trustees that the audited financial statements be included in the Trust's annual report to shareholders for the Trust's 2024 fiscal year for filing with the SEC.

The members of each Trust's Audit Committee are: Steven E. Buller, John A. Caroselli, Peter D. Jones, Clarence Otis, Jr., and Darrell A. Williams.

To the extent required by applicable regulations, pre-approval by the Audit Committee of the Board is needed for all audit and permissible non-audit services rendered by the Independent Registered Public Accounting Firm to each Trust and all permissible non-audit services rendered by the Independent Registered Public Accounting Firm to MFS and any entity controlling, controlled by or under common control with MFS that provides ongoing services to a Trust (including MFS Service Center, Inc.) (each, a "Service Affiliate") if the services relate directly to the operations and financial reporting of such Trust. 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; 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.

Schedule A attached hereto includes tables that set forth for each Trust's two most recent fiscal years, the fees billed by each Trust's Independent Registered Public Accounting Firm for (a) all audit and non-audit services provided directly to the Trust and (b) those non-audit services provided to each Trust's Service Affiliates that relate directly to the Trust's operations and financial reporting under the following captions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Audit Fees — fees related to the audit and review of the financial statements included in annual reports and registration statements, and other services that are normally provided in connection with statutory and regulatory filings or engagements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Audit-Related Fees — 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 (inclusive of annual review of basic maintenance testing associated with the Preferred Shares), attestation reports, comfort letters and internal control reviews.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) Tax Fees — fees associated with tax compliance, tax advice and tax planning, including services relating to the regulated investment company qualification reviews and tax distribution and analysis reviews.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) All Other Fees — fees for products and services provided to a Trust by the Independent Registered Public Accounting Firm other than those reported under "Audit Fees," "Audit-Related Fees," and "Tax Fees."

Schedule A attached hereto also sets forth the aggregate fees billed by each Independent Registered Public Accounting Firm for each Trust's two most recent fiscal years for non-audit services rendered to each Trust and each Trust's Service Affiliates.

The Audit Committee has considered whether the provision by each Trust's Independent Registered Public Accounting Firm of non-audit services to each Trust's Service Affiliates that were not pre-approved by the Audit Committee because such services did not relate directly to the operations and financial reporting of each Trust was compatible with maintaining the independence of the Independent Registered Public Accounting Firm as each Trust's principal auditor.

#### Officers
The officers of the Trusts, as of August 1, 2025, are listed below, together with their principal occupations during the past five years (their titles may have varied during that period). Each officer will hold office until his or her successor is chosen and qualified, or until he or she retires, resigns or is removed from office.

#### Interests of Certain Persons

------

#### SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
Section 30(h) of the 1940 Act and Section 16(a) of the Securities Exchange Act of 1934 require certain reporting persons to file reports of ownership and changes in ownership with the SEC and the New York Stock Exchange. Such persons are required by SEC regulations to furnish each Trust with copies of all Section 16(a) forms they file in relation to that Trust. Based solely on its review of the copies of such reports received by it, or written representations from certain reporting persons, each Trust believes all Section 16(a) transactions were reported on a timely basis, except a late filing of Form 3 was made on behalf of Kasey Phillips (Treasurer) in connection with her appointment as Treasurer of the Trusts due to an administrative oversight by the Trusts' administrator. Ms. Phillips did not own shares of the Trusts, and the late filing did not involve a failure to report trading in the Trusts' shares.

#### FURTHER INFORMATION ABOUT VOTING AND THE MEETING

#### Manner of Voting Proxies
All proxies received by management will be voted on all matters presented at the Meeting, and if not limited to the contrary, will be voted FOR the election of Maureen R. Goldfarb, John P. Kavanaugh, Maryanne L. Roepke, Paula E. Smith, and Laurie J. Thomsen as Trustees of the Trust (if still available for election).

All proxies received, including proxies that reflect (i) broker non-votes (i.e., shares held by brokers or nominees as to which (a) instructions have not been received from the beneficial owners or the persons entitled to vote, and (b) the broker or nominee does not have discretionary voting power on a particular matter), (ii) abstentions or (iii) the withholding of authority to vote for a nominee for election as Trustee, will be counted as shares that are present on a particular matter for purposes of determining the presence of a quorum for that matter. A majority of the outstanding shares of MFS High Income Municipal Trust, MFS Investment Grade Municipal Trust, and MFS Intermediate High Income Fund, entitled to be cast at the Meeting that are present in person or represented by proxy constitutes a quorum, and thirty percent (30%) of the outstanding shares of MFS Charter Income Trust, MFS Government Markets Income Trust, MFS High Yield Municipal Trust, MFS Intermediate Income Trust, MFS Multimarket Income Trust, and MFS Municipal Income Trust entitled to be cast at the Meeting that are present in person or represented by proxy constitutes a quorum. With respect to the election of John P. Kavanaugh and Maryanne L. Roepke as Trustees of MFS High Yield Municipal Trust, and MFS Municipal Income Trust, a quorum also requires thirty percent (30%) of each Trust's outstanding preferred shares entitled to vote at the Meeting present in person or by proxy. With respect to the election of John P. Kavanaugh and Maryanne L. Roepke as Trustees of MFS High Income Municipal Trust and MFS Investment Grade Municipal Trust, a quorum requires a majority of each Trust's outstanding preferred shares entitled to vote at the Meeting present in person or by proxy. With respect to the election of Trustees, other than the election of John P. Kavanaugh and Maryanne L. Roepke as Trustees of MFS Municipal Income Trust, neither broker non-votes nor abstentions nor withholding authority to vote have any effect on the outcome of the voting. With respect to the election of John P. Kavanaugh and Maryanne L. Roepke as Trustees of MFS Municipal Income Trust, broker non-votes, abstentions and withholding authority to vote have the effect of a vote against their elections as Trustees.

Each shareholder of a Trust is entitled to one vote for each share of the Trust that such shareholder owns at the close of business on July 31, 2025, on each matter on which the shareholder is entitled to vote. Each fractional share is entitled to a proportionate fractional vote.

Each Trust will reimburse the record holders of its shares for their reasonable expenses incurred in sending proxy material to and obtaining voting instructions from beneficial owners.

Each Trust knows of no other matters to be brought before the Meeting. If, however, because of any unexpected occurrence, any nominee is not available for election or if any other matters properly come before the Meeting, it is each Trust's intention that proxies not limited to the contrary will be voted in accordance with the judgment of the persons named in the enclosed form of proxy.

#### Instructions for Voting Proxies
The giving of a proxy will not affect a shareholder's right to vote in person should the shareholder decide to attend the Meeting. To vote by mail, please mark, sign, date and return the enclosed proxy card following the instructions printed on the card. Please refer to your proxy card for instructions for voting by telephone or internet.

------

High Income Fund, MFS Intermediate Income Trust, MFS Investment Grade Municipal Trust, MFS Multimarket Income Trust, and MFS Municipal Income Trust.

#### Other Business
The Trustees know of no matters other than those described in this proxy statement to be brought before the annual meeting.

On July 10, 2023, Bulldog Investors, LLP ("Bulldog"), on behalf of Special Opportunities Fund, provided notice to each of MFS Investment Grade Municipal Trust and MFS High Yield Municipal Trust of its intention to submit shareholder proposals for consideration at the Meeting, requesting that each such Fund's shareholders vote i) to elect two individuals nominated by Bulldog as Trustees of the Fund and ii) to approve a non-binding proposal that the Board of the Fund consider authorizing a liquidity event that will allow shareholders to monetize a significant percentage of their shares at or close to each Fund's net asset value. The two Funds, MFS, and Bulldog reached an agreement (the "Settlement Agreement") pursuant to which Bulldog agreed that it will not formally submit its shareholder proposals for consideration at the Meeting, unless the average trading discount of the shares was equal to or less than 7.50% for the entirety of a consecutive 30 calendar day period (the "Discount Threshold") prior to July 15, 2025. On July 15, 2025, the Settlement Agreement was amended to, among other things, extend the deadline for each of the Funds to satisfy the Discount Threshold until December 31, 2025.

#### Additional Information
The Meeting of shareholders of each Trust is called to be held at the same time as the Meetings of shareholders of each of the other Trusts. It is anticipated that all Meetings will be held simultaneously.

If any shareholder at the Meeting objects to the holding of a simultaneous Meeting and moves for an adjournment of the Meeting to a time promptly after the simultaneous Meetings, the persons named as proxies will vote in favor of such adjournment.

In the event that a quorum is not present for purposes of acting on the proposal, or if sufficient votes on the proposal set forth in the Notice of Annual Meeting of Shareholders are not received by the time of the Meeting, the persons named as proxies may propose one or more adjournments of the Meeting or postponements from time to time, with no other notice than an announcement at the Meeting, in order to permit further solicitation of proxies for the proposal. Any adjournment will require the affirmative vote of a majority of the votes properly cast on the question in person or by proxy at the session of the Meeting to be adjourned. The persons named as proxies will vote in favor of adjournment those proxies that they are entitled to vote in favor of such adjournment and will vote against any such adjournment all other proxies. Your Trust pays the costs of any additional solicitation and of any adjourned session. Any proposals for which sufficient votes in accordance with the Trustees' recommendations have been received by the time of the Meeting may be acted upon and considered final regardless of whether the Meeting is adjourned to permit additional solicitation with respect to any other proposal.

As part of our effort to maintain a safe and healthy environment at the Meeting, each Trust and the Trustees monitor statements issued by the Centers for Disease Control and Prevention (www.cdc.gov). For that reason, the Trustees reserve the right to reconsider the date, time and/or means of convening each Trust's meeting. Subject to any restrictions imposed by applicable law, the Trustees may choose to conduct the meeting solely by means of remote communications, or may hold a "hybrid" meeting where some participants attend in person and others attend by means of remote communications. If the Trustees choose to change the date, time and/or means of convening a Trust's meeting, the Trust will announce the decision to do so in advance, and details on how to participate will be issued by press release and filed with the SEC as additional proxy material.

The expense of the preparation, printing and mailing of the enclosed form of proxy, the Notice and this Proxy Statement, and any tabulation costs, will be borne on a proportional basis by the Trusts.

Annual reports will be sent to shareholders of record of each Trust following each Trust's fiscal year end. A copy of each Trust's most recent annual report and semi-annual report may be obtained without charge at closedendfunds.mfs.com or by

Unless a Trust receives contrary instructions, only one copy of this Proxy Statement will be mailed to a given address where two or more shareholders share that address.
