PROPOSAL 1

ELECTION OF BOARD OF DIRECTORS

Introduction

Stockholders of each fund are being asked to consider the election of Craig C. MacKay, Thomas J. Perna and Fred J. Ricciardi to the Board of Directors of each fund.

Mr. MacKay, Mr. Perna and Mr. Ricciardi stand for election as their terms expire in 2024. Mr. MacKay was elected as a Director of Pioneer Diversified High Income Fund, Inc., Pioneer Floating Rate Fund, Inc. and Pioneer High Income Fund, Inc. in March 2021, and was most recently elected by stockholders of such funds in 2021. Each of Mr. Perna and Mr. Ricciardi currently serves as a Director of each fund and has served in that capacity continuously since originally elected. Mr. Perna has served as a Director of Pioneer Floating Rate Fund, Inc. and Pioneer High Income Fund, Inc. since 2006, and Pioneer Diversified High Income Fund, Inc. since 2007. Mr. Perna was most recently elected by stockholders of such funds in 2021. Mr. Ricciardi has served as a Director of Pioneer Diversified High Income Fund, Inc., Pioneer Floating Rate Fund, Inc. and Pioneer High Income Fund, Inc. since 2014, and was most recently elected by stockholders of such funds in 2021. If elected, each of Mr. MacKay, Mr. Perna and Mr. Ricciardi shall hold office for a three-year term and until his successor is elected and qualified.

Each nominee has consented to being named in this proxy statement and indicated his willingness to serve if elected. In the unanticipated event that any nominee should be unable to serve, the persons named as proxies may vote for such other person as shall be designated by each of the fund’s Board of Directors. The persons named on the accompanying proxy card intend to vote at the meeting (unless otherwise directed) for the election of Mr. MacKay, Mr. Perna and Mr. Ricciardi as Directors of each fund.

On July 9, 2024, Amundi, the parent company of Amundi Asset Management US, Inc. (the “Adviser”), each fund’s investment adviser, announced that it had entered into a definitive agreement with Victory Capital Holdings, Inc. (“Victory Capital”) to combine the Adviser with Victory Capital, and for Amundi to become a strategic shareholder of Victory Capital (the “Transaction”). The closing of the Transaction is subject to certain regulatory approvals and other conditions. There is no assurance that the Transaction will close.

The closing of the Transaction would cause each fund’s current investment advisory agreement with the Adviser to terminate. Under the terms of the Transaction, each fund’s Board of Directors will be asked to approve a new investment advisory agreement for the fund with Victory Capital Management Inc., an affiliate of Victory Capital. If approved by the Board, each fund’s new investment advisory agreement will be submitted to the stockholders of the fund for their approval at a special meeting of stockholders. There is no assurance that the Board of a fund will approve the new investment advisory agreement. Other changes to the funds, including changes to each fund’s Board, also may be submitted to stockholders for their approval. Neither the Governance and Nominating Committee nor the Board of Directors have considered any other proposed directors.

Stockholders are not being asked to consider approval of a new investment advisory agreement or any other proposals related to the Transaction at this annual meeting.

Director Class Designations and Terms of Office

Each fund’s bylaws (“Bylaws”) provides that a majority of the Board may establish, increase or decrease the number of Directors of the fund, provided that the number thereof shall never be less than the minimum number required by the Maryland General Corporation Law (the “MGCL”) nor more than fifteen Directors. Each fund currently has nine Directors.

Pursuant to each fund’s charter, each fund’s Board is divided into three staggered term classes - Class I, Class II and Class III. The Directors of only one class are elected at each annual meeting so that the regular term of only one class of Directors will expire at each annual meeting and any particular Director stands for election every third annual meeting of stockholders.

Each class of Directors will stand for election at the conclusion of its respective term. Such classification may prevent replacement of a majority of the Directors for up to two annual meetings.

Each Director holds office until his or her successor shall have been duly elected and qualify. Any Director nominated for re-election as a Director who fails to receive the requisite vote for re-election at an annual meeting of stockholders, and whose successor has neither been elected nor qualified, shall holdover. Except as otherwise provided by applicable law, such holdover Director shall continue to serve as Director until his or her successor is elected and qualified, or until he or she sooner dies, resigns, retires or is disqualified or removed from office as provided in each fund’s Charter.

Mr. Baumgardner is Of Counsel to Sullivan & Cromwell LLP, which acts as independent outside legal counsel to the Independent Directors of each Pioneer Fund.

Ms. Jones and Mr. Pirondini are Interested Directors because they are an officer or director of each fund’s investment adviser and certain of its affiliates.

Responsibilities of the Board of Directors

The Board is responsible for overseeing each fund’s management and operations. The Chairman of the Board is an Independent Director. Independent Directors constitute at least 75% of the Board.

During the most recent fiscal year of each of Pioneer Diversified High Income Fund, Inc. and Pioneer High Income Fund, Inc. the Board held 8 meetings. During the most recent fiscal year of Pioneer Floating Rate Fund, Inc., the Board held 7 meetings. All of the current Directors and committee members of each fund then serving attended at least 75% of the meetings of the Board and applicable committees, if any, held during that fund’s most recent fiscal year.

The funds do not have a policy on Director attendance at the annual meeting. For each fund, one Director attended the 2023 annual meeting of stockholders.

The Directors were selected or nominated to join the Board based upon the following as to each Board member: such person’s character and integrity; such person’s judgment, analytical ability, intelligence, and common sense; such person’s experience and previous profit and not-for-profit board membership; such person’s demonstrated willingness to take an independent and questioning stance toward management; such person’s willingness and ability to commit the time necessary to perform the duties of a Director; as to each Independent Director, his or her status as not being an “interested person” as defined under the 1940 Act; and, as to Ms. Jones and Mr. Pirondini, their association with Amundi US. Each Director also serves on the Boards of Directors of other exchange-listed closed-end funds, a closed-end interval fund, and open-end funds, all part of the Pioneer Funds complex, and has substantial experience protecting fund stockholders’ interests. As part of their service on the boards of Pioneer closed-end funds’, the nominees regularly evaluate issues unique to closed-end funds, including the discount at which closed-end funds’ shares may trade relative to their net asset value per share. Each of the Independent Directors also was selected to join the Board based on the criteria and principles set forth in the charter of each fund’s Governance and Nominating Committee, as then in effect. In addition to individual attributes, the value of diversity is considered. In evaluating an incumbent Director’s prospective service on the Board, the Director’s experience in, and ongoing contributions toward, overseeing that fund’s business as a Director also are considered.

In addition, the following specific experiences, qualifications, attributes and/or skills apply as to each Director: Mr. Baumgardner, legal, investment management, business and public company experience as an attorney practicing investment management, corporate and securities law and experience as a board member of other organizations; Ms. Durnin, investment management and investment company experience as an executive officer of an investment adviser; Dr. Friedman, academic leadership, economic and finance experience and investment company board experience; Mr. MacKay, investment, financial and business experience as a partner in an investment banking firm and experience as a board member of other organizations; Ms. Monchak, investment, financial and business experience, including as the chief investment officer of a pension fund; Mr. Perna, accounting, financial,

and business experience as an executive officer and experience as a board member of other organizations; Mr. Ricciardi, financial, business and investment company experience as an executive officer of a financial and investment company services organization, and experience as a board member of offshore investment companies and other organizations; Ms. Jones, investment management experience as an executive and leadership roles with Amundi US and its affiliates; and Mr. Pirondini, portfolio management experience and leadership roles with Amundi US. However, in its periodic assessment of the effectiveness of the Board, the Board considers the complementary skills and experience of individual Directors primarily in the broader context of the Board’s overall composition so that the Board, as a body, possesses the appropriate (and appropriately diverse) skills and experience to oversee the business of the fund.

Under the MGCL, the appointment, designation (including in any proxy or registration statement or other document) of a Director as an expert on any topic or in any area, or as having experience, attributes or skills in any area, or any other appointment, designation or identification, does not impose on that person any standard of care or liability that is greater than that imposed on that person as a Director in the absence of the appointment, designation or identification, and no Director who has special attributes, skills, experience or expertise, or is appointed, designated, or identified as aforesaid, is held to a higher standard of care by virtue thereof.

Board Committees

The Board currently has four standing committees: the Independent Directors Committee, the Audit Committee, the Governance and Nominating Committee and the Policy Administration Committee. Each committee is chaired by an Independent Director (the “Chairs”) and all members of each committee are Independent Directors.

The Chairs of the committees work with the Chairman of the Board and fund management in setting the agendas for Board meetings. The Chairs of the committees set the agendas for committee meetings with input from fund management. As noted below, through the committees, the Independent Directors consider and address important matters involving the funds, including those presenting conflicts or potential conflicts of interest for management. The Independent Directors also regularly meet without the presence of management and are advised by independent legal counsel. The Board believes that the committee structure, and delegation to the committees of specified oversight responsibilities, help the Board more effectively to provide governance and oversight of the funds’ affairs. Mr. Perna, Chairman of the Board, is a member of each committee except the Audit Committee and the Valuation Committee*, each of which he is a non-voting, ex-officio member.

During the most recent fiscal year for each fund, the Audit Committee, Governance and Nominating Committee, Independent Directors Committee, Policy Administration Committee and Valuation Committee* of each fund held the following meetings:

The Valuation Committee was combined with the Audit Committee on January 22, 2024.

Independent Directors Committee: John E. Baumgardner, Jr., Diane Durnin, Benjamin M. Friedman, Craig C. MacKay, Lorraine H. Monchak, Thomas J. Perna (Chair) and Fred J. Ricciardi.

The Independent Directors Committee is comprised of all of the Independent Directors. The Independent Directors Committee serves as the forum for consideration of a number of issues required to be considered separately by the Independent Directors under the 1940 Act, including the assessment and review of each fund’s advisory agreement and other related party contracts. The Independent Directors Committee also considers issues that the Independent Directors believe it is advisable for them to consider separately from the Interested Directors.

Audit Committee: Benjamin M. Friedman, Craig C. MacKay, Lorraine H. Monchak and Fred J. Ricciardi (Chair).

Each fund’s Audit Committee is comprised of only Independent Directors who are “independent” as defined in the applicable New York Stock Exchange (“NYSE”) and NYSE American (Pioneer Diversified High Income Fund, Inc.) listing standards relating to closed-end funds. The Board of each fund has adopted a charter for the Audit Committee. In accordance with its charter, the purposes of the Audit Committee are to:

•

Assist the Board’s oversight and monitoring of: (i) the integrity of the fund’s financial statements; (ii) the fund’s compliance with legal and regulatory requirements; (iii) the independent registered public accounting firm’s qualifications, performance and independence; and (iv) the performance of the fund’s internal audit function; and

•

Prepare the disclosure required by Item 407(d)(3)(i) of Regulation S-K to be included in the fund’s annual proxy statement and other filings.

The Audit Committee charter is available on Amundi US’s website: amundi.com/US. You also can obtain a copy by sending a written request to your fund at the address listed on this proxy statement. The information contained on Amundi US’s website is not part of, or incorporated by reference in, this proxy statement.

In addition, the Audit Committee reviews the reports and other information provided to the Committee by Amundi US, as the valuation designee of the Fund, and assists the Board in the oversight of Amundi US as the valuation designee of the funds

Each fund’s Board has determined that the fund has at least one audit committee financial expert serving on its Audit Committee. Mr. Ricciardi, an Independent Director, serves on each Audit Committee and has been determined to be an audit committee financial expert.

Audit Committee Report

The Audit Committee reports that it has (1) reviewed and discussed each fund’s audited financial statements with management; (2) discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the Securities and Exchange Commission (the “SEC”); and (3) received written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence, and discussed with the independent registered public accounting firm that firm’s independence. Based upon the review and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Annual Report for Pioneer Floating Rate Fund, Inc. for the fiscal year ended November 30, 2023, the Annual Report for Pioneer High Income Fund, Inc. for the fiscal year ended March 31, 2024 and the Annual Report for Pioneer Diversified High Income Fund, Inc. for the fiscal year ended April 30, 2024.

The members of each fund’s Audit Committee are:

Benjamin M. Friedman
Craig C. MacKay
Lorraine H. Monchak
Fred J. Ricciardi (Chair)

Governance and Nominating Committee: John E. Baumgardner, Jr. (Chair), Diane Durnin, and Thomas J. Perna.

All members of the Governance and Nominating Committee are independent under the applicable NYSE and NYSE American listing standards relating to closed-end funds, and are not “interested persons,” as defined in the 1940 Act, of each fund. The Board of each fund has adopted a written charter for the Governance and Nominating Committee, which is available on Amundi US’s website: amundi.com/US. You also can obtain a copy by sending a written request to your fund at the address listed on this proxy statement.

The Governance and Nominating Committee considers governance matters affecting the Board and each fund. Among other responsibilities, the Governance and Nominating Committee reviews the performance of the Independent Directors as a whole, and reviews and recommends to the Independent Directors Committee any appropriate changes concerning, among other things, the size and composition of the Board, the Board’s

committee structure and the Independent Directors’ compensation. The Governance and Nominating Committee also makes recommendations to the Independent Directors Committee or the Board on matters delegated to it.

In addition, the Governance and Nominating Committee screens potential candidates for Independent Directors. Among other responsibilities, the Governance and Nominating Committee reviews periodically the criteria for Independent Directors and the spectrum of desirable experience, expertise and characteristics for Independent Directors as a whole, and reviews periodically the qualifications and requisite skills of persons currently serving as Independent Directors and being considered for re-nomination. The Governance and Nominating Committee also reviews the qualifications of any person nominated to serve on the Board by a stockholder or recommended by any Director, management or another person and makes a recommendation as to the qualifications of such nominated or recommended person to the Independent Directors and the Board, and reviews periodically the Committee’s procedure, if any, regarding candidates submitted by stockholders. The Governance and Nominating Committee also strives to achieve diversity of the Board with respect to attributes such as race, ethnicity, gender, cultural background and professional experience when reviewing candidates for any Board vacancies. The Directors who are not Independent Directors and the officers of each fund are nominated and selected by the Board.

The Governance and Nominating Committee does not have specific, minimum qualifications for nominees, nor has it established specific qualities or skills that it regards as necessary for one or more of the Independent Directors to possess (other than qualities or skills that may be required by applicable law or regulation). However, in evaluating a person as a potential nominee to serve as an Independent Director, the Governance and Nominating Committee will consider the following general criteria and principles, among any others that it may deem relevant: (i) the nominee’s reputation for integrity, honesty and adherence to high ethical standards; (ii) the nominee’s business acumen and ability to exercise sound judgment in matters that relate to the current and long-term objectives of the fund and whether the person is willing and able to contribute positively to the decision-making process of the fund; (iii) the nominee’s commitment and ability to devote the necessary time and energy to be an effective Independent Director, to understand the fund and the responsibilities of a director of an investment company; (iv) the nominee’s ability to understand the sometimes conflicting interests of the fund and the management company, and to act in the interests of the fund; (v) whether the nominee has, or appears to have, a conflict of interest that would impair his or her ability to represent the interests of all stockholders and to fulfill the responsibilities of a director; (vi) that nominees shall not be discriminated against on the basis of race, religion, national origin, sex, sexual orientation, disability or any other basis proscribed by law; (vii) nominees should have, or be willing to acquire, an appreciation and understanding for the oversight of publicly offered investment companies and the management, administration and distribution services provided by service providers to the companies and their shareholders, and the regulatory context within which these activities are carried out; (viii) nominees should have a collegial, collaborative approach: people who will work efficiently, effectively and in the spirit of

candor and respect for fellow board members and the staffs of the service providers; (ix) nominees should have the willingness and ability to serve on appropriate committees, and contribute to and engage meaningfully in the deliberations thereof; and (x) nominees should be committed to diversity and inclusion among Board members.

The Governance and Nominating Committee also will consider whether the nominee has the experience or skills that the Governance and Nominating Committee believes would maintain or enhance the effectiveness of the Independent Directors’ oversight of each fund’s affairs, based on the then current composition and skills of the Independent Directors and experience or skills that may be appropriate in light of changing business conditions and regulatory or other developments. The Governance and Nominating Committee does not necessarily place the same emphasis on each criterion.

The Governance and Nominating Committee does not have a formal procedure for the implementation, or for assessing the effectiveness, of its policy with regard to the consideration of the value of diversity on the Board in reviewing potential nominees for Independent Director. However, as noted above, in its periodic assessment of the effectiveness of the Board, the Board considers the complementary skills and experience of individual Directors in the context of the Board’s overall composition so that the Board, as a body, possesses the appropriate (and appropriately diverse) skills and experience to oversee the business of the funds. In addition, the Governance and Nominating Committee charter provides that the Committee shall strive to achieve diversity of the Board with respect to attributes such as race, ethnicity, gender, cultural background and professional experience when reviewing candidates for any Board vacancies, and further provides, as noted above, that nominees shall not be discriminated against on the basis of race, religion, national origin, sex, sexual orientation, disability or any other basis proscribed by law.

In the event that a vacancy arises or a change in Board membership is determined to be advisable, the Governance and Nominating Committee will, in addition to any stockholder recommendations, evaluate candidates identified by other means, including candidates proposed by Independent Directors or management. While it has not done so in the past, the Governance and Nominating Committee may retain a consultant to assist the committee in a search for a qualified candidate.

The Governance and Nominating Committee will consider recommendations for board membership by stockholders. In evaluating a nominee recommended by a stockholder, the Governance and Nominating Committee, in addition to the criteria discussed above, may consider the objectives of the stockholder in submitting that nomination and whether such objectives are consistent with the interests of all stockholders. If the Board determines to include a stockholder’s candidate among the slate of Board nominees, the candidate’s name will be placed on that fund’s proxy card.

The Governance and Nominating Committee initiated the recommendation of each of the non-interested nominees to serve as an Independent Director.

With respect to the re-nomination of an existing Independent Director, the Governance and Nominating Committee and the Independent Directors Committee use the criteria and the principles set forth above, as revised from time to time, to guide the selection process.

Stockholders may communicate with the members of the Board as a group or individually. Any such communication should be sent to the Board or an individual Director c/o the Secretary of the fund at the address on the notice of this annual meeting. The Secretary may determine not to forward any communication to members of the Board that does not relate to the business of a fund.

Policy Administration Committee: Thomas J. Perna (Chair), John E. Baumgardner, Jr., and Diane Durnin.

The Policy Administration Committee, among other things, oversees and monitors each fund’s compliance with legal and regulatory requirements that are not directly related to financial reporting, internal financial controls, independent audits or the performance of the fund’s internal audit function. The Policy Administration Committee also oversees the adoption and implementation of certain of the funds’ policies and procedures.

Oversight of Risk Management

Consistent with its responsibility for oversight of each fund in the interests of stockholders, the Board has established a framework for the oversight of various risks relating to the funds, including the oversight of the identification of risks and the management of certain identified risks. The Board has delegated certain aspects of its risk oversight responsibilities to the committees, but relies primarily on Amundi US and its affiliates for the identification and management or mitigation of risks relating to their management activities on behalf of the funds, as well as to oversee and advise the Board on the risks that may arise relating to the activities of other fund service providers.

Each fund faces a number of risks, such as investment risk, counterparty risk, valuation risk, enterprise risk, reputational risk, cybersecurity risk, risk of operational failure or lack of business continuity, and legal, compliance and regulatory risk. The goal of risk management is to identify and address risks, i.e., events or circumstances that could have material adverse effects on the business, operations, stockholder services, investment performance or reputation of a fund.

Most of the funds’ investment management and business operations are carried out by or through Amundi US, its affiliates, and other service providers (such as the custodian and fund accounting agent and the transfer agent), each of which has an independent interest in risk management but whose policies and the methods by which one or more risk management functions are carried out may differ from each fund’s and each other’s in the setting of priorities, the resources available or the effectiveness of relevant controls. Operational or other failures, including cybersecurity failures, at any one or more of the funds’ service providers could have a material adverse effect on a fund and its stockholders.

Under the overall supervision of the Board or the applicable committee of the Board, each fund, or Amundi US and the affiliates of Amundi US, or other service providers to each fund employ a variety of processes, procedures and controls in an effort to identify, address and mitigate risks. Different processes, procedures and controls are employed with respect to different types of risks. Various personnel, including the funds’ and Amundi US’s chief compliance officer and Amundi US’s chief risk officer and director of internal audit, as well as various personnel of Amundi US and of other service providers, make periodic reports to the applicable committee or to the Board with respect to various aspects of risk management. The reports received by the Directors related to risks typically are summaries of relevant information.

The Board recognizes that not all risks that may affect a fund can be identified, that it may not be practical or cost-effective to eliminate or mitigate certain risks, that it may be necessary to bear certain risks (such as investment-related risks) to achieve each fund’s goals, that the processes, procedures and controls employed to address certain risks may be limited in their effectiveness, and that some risks are simply beyond the control of the funds or Amundi US and its affiliates or other service providers. Because most of the funds’ operations are carried out by various service providers, the Board’s oversight of the risk management processes of those service providers, including processes to address cybersecurity and other operational failures, is inherently limited. As a result of the foregoing and other factors, each fund’s ability to manage risk is subject to substantial limitations.

It is important to note that each fund is designed for investors that are prepared to accept investment risk, including the possibility that as yet unforeseen risks may emerge in the future.

The following table indicates the value of shares that each Director or nominee beneficially owned in each fund and Pioneer Funds in the aggregate as of May 31, 2024, the most recent practicable date prior to the filing of this Proxy Statement with the SEC. Beneficial ownership is determined in accordance with SEC Rule 13d-3(d)(1). The share value of any closed-end Pioneer fund is based on its closing market price on May 31, 2024. The share value of any open-end Pioneer fund is based on the net asset value of the class of shares on May 31, 2024. The dollar ranges in this table are in accordance with SEC requirements.

Compensation of Directors and Executive Officers

The Independent Directors review and set their compensation annually, taking into consideration the committee and other responsibilities assigned to specific Directors and attendance at meetings. The compensation paid to the Directors is then allocated among the funds as follows:

•

each fund with assets less than $250 million pays each Independent Directors an annual fee of $1,000.

•

the remaining compensation of the Independent Directors is allocated to each fund with assets greater than $250 million based on the fund’s net assets.

•

the Interested Directors receive an annual fee of $500 from each fund, except in the case of funds with net assets of $50 million or less, which pay each Interested Directors an annual fee of $200. Amundi US reimburses these funds for the fees paid to the Interested Directors.

Each fund does not pay any salary or other compensation to its executive officers, none of whom are employees of the funds. Amundi US or its affiliates compensate the funds’ executive officers, who are also officers or employees of Amundi US or its affiliates. The funds pay a portion of the chief compliance officer’s compensation for his services as the funds’ chief compliance officer. Amundi US pays the remaining portion of the chief compliance officer’s compensation.

No Director has pension or retirement benefits accrued as a part of fund expenses.

The following tables set forth certain information with respect to the compensation paid to the Directors/nominees by each fund and by all funds in the Fund Complex for the fund’s most recent fiscal year.^†

Ernst & Young LLP served as the independent registered public accounting firm for Pioneer High Income Fund, Inc. for the fiscal year ended March 31, 2023, Pioneer Diversified High Income Fund, Inc. for the fiscal year ended April 30, 2023, and Pioneer Floating Rate Fund, Inc. for the fiscal years ended November 30, 2023 and November 30, 2022. Deloitte & Touche LLP served as the independent registered public accounting firm for Pioneer High Income Fund, Inc. for the fiscal year ended March 31, 2024 and Pioneer Diversified High Income Fund, Inc. for the fiscal year ended April 30, 2024.

During the periods that Ernst & Young LLP served as each fund’s independent registered public accounting firm, including each fund’s two most recent fiscal years, Ernst & Young LLP’s reports on each fund’s financial statements have not contained an adverse opinion or disclaimer of opinion and have not been qualified or modified as to uncertainty, audit scope or accounting principles. During the periods that Ernst & Young LLP served as each fund’s independent registered public accounting firm, including each fund’s two most recent fiscal years, there were no disagreements with Ernst & Young LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Ernst & Young LLP, would have caused Ernst & Young LLP to make reference to the subject matter of the disagreement in connection with its reports on the financial statements for such periods. In addition, there have been no reportable events related to the funds, as that term is defined in Item 304 (a)(1)(v) of Regulation S-K under the Securities Exchange Act of 1934.

Affiliates’ Fees for Non-Audit Services Required to be Pre-Approved

Each fund’s Audit Committee is required to pre-approve services to affiliates as defined by SEC rules to the extent that the services relate directly to the operations or financial reporting of the fund. Affiliates include the fund’s investment adviser and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the fund (hereinafter referred to as “affiliates” of the fund). For the fiscal years ended March 31, 2024 and 2023, for Pioneer High Income Fund, Inc., there were no services provided to an affiliate that required the fund’s Audit Committee pre-approval. For the fiscal years ended April 30, 2024 and 2023, for Pioneer Diversified High Income Fund, Inc., there were no services provided to an affiliate that required the fund’s Audit Committee pre-approval. For the fiscal years ended November 30, 2023 and 2022, for Pioneer Floating Rate Fund, Inc., there were no services provided to an affiliate that required the fund’s Audit Committee pre-approval.

General Audit Committee Approval Policy

•

For all projects, each of the officers of the funds and the funds’ independent registered public accounting firm will make an assessment to determine that any proposed projects will not impair independence.

•

Potential services will be classified into the four non-restricted service categories and the “Approval of Audit, Audit-Related, Tax and Other Services” Policy will be applied. Any services outside the specific pre-approved service subcategories set forth above must specifically be approved by each fund’s Audit Committee.

•

At least quarterly, each fund’s Audit Committee shall review a report summarizing the services by service category, including fees, provided by the independent registered public accounting firm as set forth in the above policy.

The charter of each Audit Committee requires that the Audit Committee shall approve (a) all audit and non-audit services to be provided to each fund and (b) all non-audit services to be provided by the fund’s independent public accounting firm to Amundi US and any entity controlling, controlled by or under common control with the investment adviser that provides ongoing services to the fund (“Covered Service Providers”) if the engagement relates directly to the operations and financial reporting of the fund. The Audit Committee may delegate, to the extent permitted by law, pre-approval responsibilities to one or more members of the Audit Committee who shall report to the full Audit Committee.

The Audit Committee may not approve non-audit services that the Audit Committee believes may impair the independence of the independent registered public accounting firm. Permissible non-audit services include any professional services (including tax services) that are not prohibited services as described below provided to the fund by the independent registered public accounting firm, other than those provided to a fund in connection with an audit or a review of the financial statements of the fund. Permissible non-audit services may not include (a) bookkeeping or other services related to the accounting records or financial statements of the fund; (b) financial information systems design and implementation; (c) appraisal or valuation services, fairness opinions or contribution-in-kind reports; (d) actuarial services; (e) internal audit outsourcing services; (f) management functions or human resources; (g) broker or dealer, investment adviser or investment banking services; (h) legal services and expert services unrelated to the audit; and (i) any other service the Public Company Accounting Oversight Board determines, by regulation, is impermissible.

Pre-approval by each fund’s Audit Committee of any permissible non-audit services is not required so long as: (a) the aggregate amount of all such permissible non-audit services provided to a fund, Amundi US and any Covered Service Provider constitutes not more than 5% of the total amount of revenues paid to the independent registered public accounting firm during the fiscal year in which the permissible non-audit services are provided to (i) the fund, (ii) Amundi US and (iii) any Covered Service Provider during the fiscal year in which services are provided that would not have to be approved by the Audit Committee; (b) the permissible non-audit services were not recognized by the fund at the time of the engagement to be non-audit services; and (c) such services are promptly brought to the attention of the Audit Committee and approved by the Audit Committee (or its delegate(s)) prior to completion of the audit.

Aggregate Non-Audit Fees

The aggregate non-audit fees billed by Deloitte & Touche LLP and Ernst & Young LLP for services rendered to each fund and its affiliates, as previously defined, were as follows.

	For the fiscal year	For the fiscal year
	ended 3/31/2024	ended 3/31/2023

The Audit Committee of the Board of each fund has considered whether the provision of services, other than audit services, by Deloitte & Touche LLP to each fund and its affiliates is compatible with maintaining Deloitte & Touche LLP’s independence in performing audit services.

Representatives of Deloitte & Touche LLP will be available at the annual meeting, will have the opportunity to make a statement should they desire to do so, and will be available to answer questions.

Stockholder Proposals

Under Rule 14a-8 of the Exchange Act (relating to stockholder proposals), any stockholder proposal that may properly be included in your fund’s proxy statement for the 2025 annual meeting, must be received by the Secretary of the fund at the fund’s principal office at 60 State Street, Boston, Massachusetts 02109 at least 120 calendar days prior to the anniversary of the date the fund’s proxy statement for the 2024 annual meeting was released to its stockholders, or on or before April 23, 2025. A proposal or nomination that is not to be included in a fund’s proxy statement may be made at the 2025 annual meeting for such fund only if it is received by the Secretary of the fund at the fund’s principal office at 60 State Street, Boston, Massachusetts 02109 not earlier than 150 days (i.e., March 24, 2025) and not later than 5:00 p.m., Eastern Time, 120 days (i.e., April 23, 2025) before the anniversary of the date of the fund’s proxy materials for the 2024 annual meeting provided, however, that in the event that the date of the 2025 annual meeting for a fund is advanced or delayed by more than thirty (30) days from the anniversary date of the 2024 annual meeting, notice by a stockholder to be timely must be so delivered not earlier than the 150th day prior to the date of the 2025 annual meeting and not later than 5:00 p.m., Eastern Time, on the later of the 120th day prior to the date of the 2025 annual meeting, as originally convened, or the 10th day following the day on which public announcement of the date of such annual meeting is first made by the fund. The funds’ Bylaws require that certain information must be provided by the stockholder to the fund when notice of a nominee for election as a Director or proposal is submitted to the fund.

The submission by a stockholder of a proposal for inclusion in a proxy statement does not guarantee that it will be included. Each of Pioneer Diversified High Income Fund, Inc., Pioneer Floating Rate Fund, Inc. and Pioneer High Income Fund, Inc., currently expect to hold the next annual stockholders’ meeting on or about October 2, 2025, which date is subject to change. Stockholder proposals are subject to certain regulations under the federal securities laws.

Proxies, Quorum and Voting at the Annual Meeting

Stockholders who execute proxies or provide voting instructions by telephone or the Internet generally have the power to revoke them at any time before a vote is taken on a proposal by executing a superseding proxy or by submitting a notice of revocation to the

Secretary of the fund. In addition, although mere attendance at the meeting will not revoke a proxy, a stockholder present at the meeting may withdraw his or her proxy and vote at the meeting. All shares represented by properly executed and unrevoked proxies received in time for the meeting will be voted in accordance with the instructions contained in the proxies. If no instruction is given, the persons named as proxies will vote the shares represented thereby for the election of each of the nominees for election as a Director, as described above, and will vote in their discretion in connection with the transaction of such other business as may properly come before the meeting or any postponements or adjournments thereof.

Only stockholders of record as of the close of business on the record date are entitled to notice of and to vote at the meeting.

For each of Pioneer Diversified High Income Fund, Inc., Pioneer Floating Rate Fund, Inc. and Pioneer High Income Fund, Inc.: the presence in person or by proxy of stockholders entitled to cast a majority of the votes entitled to be cast at the meeting by holders of stock of such fund shall constitute a quorum for the transaction of business at the meeting.

An inspector of elections appointed for the meeting will determine whether a quorum is present and will tabulate votes cast at the meeting. If a quorum is not present, we expect to adjourn the annual meeting until we obtain a quorum.

Abstentions and “broker non-votes,” if any, will be treated as present for purposes of determining a quorum. “Broker non-votes” occur when a broker or nominee holding shares in “street name” does not vote on a proposal because the broker or nominee does not have discretionary voting power for that particular item and has not received instructions from the beneficial owner. However, because the funds understand that a broker or nominee may exercise discretionary voting power with respect to Proposal 1, and there are no other proposals expected to come before the meeting for which a broker or nominee would not have discretionary voting authority, the funds do not anticipate that there will be any “broker non-votes” at the meeting.

On any matter submitted to a vote of stockholders each whole share shall be entitled to one vote as to any matter on which it is entitled to vote and each fractional share shall be entitled to a proportionate fractional vote.

Stockholders may not cumulate votes for Director nominees. The last proxy card submitted by a stockholder will be counted. Stockholders do not have rights of appraisal or similar rights of dissenters in connection with the election of Directors.

As discussed more fully under Proposal 1 above, nominees must be elected by a majority of all the votes entitled to be cast at a meeting of stockholders duly called and at which a quorum is present. Because the required vote for Proposal 1 is based on the number of votes the fund’s stockholders are entitled to cast rather than on the number of votes cast, failure to vote your shares (including failure to give voting instructions to your broker, bank or other nominee), abstentions and “broker non-votes” (if any) will have the same effect as voting “AGAINST” the election of the directors.

As previously disclosed, the Board of Directors of each fund has adopted a resolution to opt in to the provisions of the Maryland Control Share Acquisition Act (“MCSAA”). Generally, the MCSAA provides that a holder of “control shares” (as defined in the MCSAA) of a Maryland corporation (e.g., a fund) acquired in a “control share acquisition” (as defined in the MCSAA) will not be entitled to vote its control shares unless the other stockholders of the corporation reinstate those voting rights. Generally, “control shares” are shares that, when aggregated with shares already owned by an acquiring person, would entitle the acquiring person to exercise 10% or more, 33 1/3% or more, or a majority of the total voting power of shares entitled to vote in the election of directors. There can be no assurance that the MCSAA will be enforceable with respect to the funds.

Adjournments

The annual meeting with respect to one or more funds may, by action of the chair of the meeting and without any action by stockholders, be adjourned from time to time with respect to one or more matters to be considered at the annual meeting to a later date and time and at a place announced at the annual meeting, whether or not a quorum is present with respect to such matter, and the meeting may be held as adjourned without further notice other than announcement at the meeting, provided that the new meeting date is not more than 120 days from the original record date. At the discretion of the chair, if a quorum is present with respect to a proposal to be considered at the meeting, a vote may be taken on the proposal prior to such adjournment. Such vote will be considered final regardless of whether the meeting is adjourned with respect to any other proposal. The meeting may be postponed prior to the meeting. If the annual meeting with respect to a fund is postponed, that fund will give notice of the postponed meeting to stockholders.

Method of Solicitation and Expenses

The cost of preparing, printing and mailing the enclosed proxy statement, accompanying Notice of Annual Meeting of Stockholders and the accompanying proxy card for each fund will be borne by that fund. In addition to soliciting proxies by mail, Amundi US may, at the funds’ expense, have one or more of the funds’ officers, representatives or compensated third-party agents, including Amundi US and Amundi Distributor US, Inc., aid in the solicitation of proxies by personal interview or telephone and may request brokerage houses and other custodians, nominees and fiduciaries to forward proxy soliciting material to the beneficial owners of the shares held of record by such persons. Each fund has retained EQ Fund Solutions, LLC to assist in the proxy solicitation. The cost of services for all solicitations covered by this proxy statement is estimated at approximately $97,100.

Each fund may also arrange to have votes recorded by telephone, the internet or other electronic means. The voting procedures used in connection with such voting methods are designed to authenticate stockholders’ identities, to allow stockholders to authorize the voting of their shares in accordance with their instructions and to confirm that their instructions have been properly recorded. In the case of telephone voting, stockholders would be called at the phone number the transfer agent, Equiniti Trust Company, has in its records for their accounts, and would be asked for their Social Security number or other identifying information. The stockholders would then be given an opportunity to

authorize proxies to vote their shares at the meeting in accordance with their instructions. In the case of automated telephone and internet voting, stockholders would be required to provide their Social Security number or other identifying information and would receive a confirmation of their instructions.

Persons holding shares as nominees will be reimbursed by the fund, upon request, for the reasonable expenses of mailing soliciting materials to the principals of the accounts.

Other Business

While the meeting has been called to transact any business that may properly come before it, the only matter that the Board intends to present is that matter stated in the attached notice of annual meeting. However, if any additional matters properly come before the annual meeting, and on all matters incidental to the conduct of the meeting, the persons named as proxies will vote in their discretion on such matters unless instructed to the contrary.
