JOINT PROXY STATEMENT

For the Annual Meetings of Shareholders
each to be held on May 28, 2025

This Joint Proxy Statement is furnished in connection with the solicitation of proxies by each Fund's Board of Trustees (each, a "Board," and collectively, the "Boards," with members of each Board being referred to as "Trustees") to be voted at the Annual Meeting of Shareholders of each Fund (each, a "Meeting," and collectively, the "Meetings") and at any adjournments or postponements thereof to be held at the offices of abrdn Inc., located at 1900 Market Street, Suite 200, Philadelphia, PA 19103 on the following dates and at the following times:

abrdn World Healthcare Fund (NYSE: THW) |  | May 28, 2025 |  | 12:30 p.m. Eastern Time |

A Notice of Annual Meetings of Shareholders and a proxy card (the "Proxy Card") accompany this Joint Proxy Statement. This Joint Proxy Statement is first being mailed on or about April 14, 2025 to shareholders of record as of April 7, 2025.

The purpose of each Meeting is to consider and act upon the following proposals (each a "Proposal"), as applicable to each Fund:

HQH — To elect two Class C Trustees to serve until the 2028 Annual Meeting of Shareholders or until such Trustee's successor is duly elected and qualified.

HQL — To elect two Class C Trustees to serve until the 2028 Annual Meeting of Shareholders or until such Trustee's successor is duly elected and qualified.

THQ — To elect two Class B Trustees to serve until the 2028 Annual Meeting of Shareholders or until such Trustee's successor is duly elected and qualified.

THW — To elect two Class A Trustees to serve until the 2028 Annual Meeting of Shareholders or until such Trustee's successor is duly elected and qualified.

All properly executed proxies received prior to a Meeting will be voted at that Meeting, or at any adjournments or postponements thereof, in accordance with the instructions marked on the Proxy Card. Unless instructions to the contrary are marked on the Proxy Card, proxies received will be voted "FOR" each Proposal. The persons named as proxy holders on the Proxy Card will vote in their discretion on any other matters that may properly come before each Meeting or any adjournments or postponements thereof. Any Proxy Card may be revoked at any time prior to its exercise by submitting a properly executed, subsequently dated Proxy Card,

3

giving written notice to Megan Kennedy, Secretary of the Fund(s), 1900 Market Street, Suite 200, Philadelphia, PA 19103, or by attending a Meeting and voting in person. Shareholders may authorize proxy voting by using the enclosed Proxy Card along with the enclosed envelope with pre-paid postage. Shareholders may also authorize proxy voting by telephone or through the internet by following the instructions contained on the Proxy Card. Shareholders do not have dissenter's rights of appraisal in connection with any of the matters to be voted on by the shareholders at each Meeting.

In order to transact business at the Meetings, a "quorum" must be present for each Meeting. Under each Fund's By-laws, a quorum is constituted by the presence in person or by proxy of the holders of a majority of the outstanding shares of the respective Fund on the record date. Abstentions and broker non-votes (i.e., proxies from brokers or nominees indicating that they have not received instructions from the beneficial owners on an item for which the brokers or nominees do not have discretionary power to vote) will be treated as present for determining whether a quorum is present with respect to a particular matter at a Meeting.

The election of a Trustee to a Board requires the affirmative vote of a plurality of the shares entitled to vote for the election of any Trustee present or represented by proxy at a Meeting with a quorum present. Under a plurality vote, the nominees who receive the highest number of votes will be elected even if they receive less than a majority of the votes. There will be no cumulative voting with respect to the proposal. For purposes of the election of Trustees, abstentions and broker non-votes will be counted as shares present for quorum purposes, but will not be treated as votes cast. Abstentions and broker non-votes, therefore, will have no effect on the election of the Trustees. All properly executed proxies received prior to the Meetings will be voted, at the Meetings or at any adjournments or postponements thereof, in accordance with the instructions marked thereon. Proxies received prior to the Meetings on which no vote is indicated will be voted "FOR" the election of the Trustees.

Brokers holding shares of a Fund in "street name" for the benefit of their customers and clients will request the instructions of such customers and clients on how to vote their shares before the Meetings. Under the rules of the New York Stock Exchange ("NYSE"), such brokers may, for certain "routine" matters, grant discretionary authority to the proxies designated by a Board to vote if no instructions have been received from their customers and clients prior to the date specified in the brokers' request for voting instructions. Each Proposal is a "routine" matter and accordingly beneficial owners who do not provide proxy instructions or who do not return a proxy card may have their shares voted by broker-dealer firms in favor of the Proposal.

The chair of a Meeting shall have the power to adjourn the Meeting without further notice other than announcement at that Meeting. Each Board of Trustees also has the power to postpone a Meeting to a later date and/or time or change the place of a Meeting (including by specifying that the Meeting will be held by remote communication) one or more times for any reason by giving, within a reasonable period of time prior to such Meeting, notice to each shareholder entitled to vote at such Meeting of the place (including that the Meeting will be held by remote communication), date and hour at which such Meeting will be held. Such notice shall be given not fewer than two (2) days before the date of such Meeting and otherwise in accordance with each Fund's By-Laws. No notice of adjournment of a Meeting to another time or place need be given to shareholders. Abstentions and broker non-votes will have the same effect at any adjourned or postponed meeting as noted above. Any business that might have been transacted at a Meeting may be transacted at any such adjourned or postponed session(s) at which a quorum is present.

We will admit to each Meeting (1) all shareholders of record on April 7, 2025 (the "Record Date"), (2) persons holding proof of beneficial ownership on the Record Date, such as a letter or account statement from the person's broker, (3) persons who have been granted proxies, and (4) such other persons that we, in our sole discretion, may elect to admit. To gain admittance, if you are a shareholder of record or a proxy holder

4

of a shareholder of record, you must bring a form of personal identification to the Meeting, where your name will be verified against our shareholder list. If a broker or other nominee holds your shares and you plan to attend a Meeting, you should bring a recent brokerage statement showing your ownership of the shares, as well as a form of personal identification. If you are a beneficial owner and plan to vote at a Meeting, you should also bring a proxy card from your broker.

Each Board has fixed the close of business on April 7, 2025 as the Record Date for the determination of shareholders entitled to notice of, and to vote at, each Meeting and at any adjournment or postponement thereof.

Each Fund has one class of shares, par value $0.01 per share. Each share of a Fund is entitled to one vote at the Meeting, and fractional shares are entitled to a proportionate share of one vote. On the Record Date, the following number of shares of each Fund were issued and outstanding:

HQH |  |  | 53,862,184.0 |  |
HQL |  |  | 28,872,416.0 |  |
THQ |  |  | 41,379,166.7 |  |
THW |  |  | 39,849,957.6 |  |

Important Notice Regarding the Availability of Proxy Materials for the Meetings to Be Held on Wednesday, May 28, 2025: The Proxy Materials and each Fund's most recent annual report for the fiscal year ended September 30, 2024 are available on the Internet at https://www.abrdnhqh.com (for HQH) https://www.abrdnhql.com (for HQL) https://www.abrdnthq.com (for THQ) and https://www.abrdnthw.com (for THW). Each Fund will furnish, without charge, a copy of its annual report for the fiscal year ended September 30, 2024 and any more recent reports, to any Fund shareholder upon request. To request a copy, please write to the Funds c/o abrdn Inc., 1900 Market Street, Suite 200, Philadelphia, PA 19103, or call 1-800-522-5465. You may also call for information on how to obtain directions to be able to register to attend a Meeting.

The Election of Trustees

Each Fund's Declaration of Trust, as amended to date (the "Declaration of Trust"), provides that its Board shall be divided into three classes with staggered terms. The term of office of each Class of Trustees for each Fund will expire in the year indicated in the following chart:

Fund |  | Class A |  | Class B |  | Class C |
HQH |  |  | 2026 |  |  |  | 2027 |  |  |  | 2028 |  |
HQL |  |  | 2026 |  |  |  | 2027 |  |  |  | 2028 |  |
THQ |  |  | 2027 |  |  |  | 2028 |  |  |  | 2026 |  |
THW |  |  | 2028 |  |  |  | 2026 |  |  |  | 2027 |  |

Each Fund's Declaration of Trust provides that a majority of its Trustees shall fix the number of the entire Board of Trustees and that such number shall be at least three and no greater than fifteen. Each Fund's Board has fixed the number of Trustees at six. Proxies will be voted for the election of the following nominees for HQH, HQL, THQ and THW. In the event that a nominee is unable to serve for any reason when the election occurs, the accompanying Proxy will be voted for such other person or persons as the applicable Fund's Board may recommend. Each nominee is presently serving as a Trustee.

5

Each Board, including the Independent Trustees, upon the recommendation of such Board's Nominating and Corporate Governance Committee, which is composed entirely of Independent Trustees, has nominated the following nominees as Trustees to its Board:

abrdn Healthcare Investors |  | Kathleen Goetz (Class C Trustee, 3 year term ending 2028) Todd Reit (Class C Trustee, 3 year term ending 2028) |
abrdn Life Sciences Investors |  | Rose DiMartino (Class C Trustee, 3 year term ending 2028) Todd Reit (Class C Trustee, 3 year term ending 2028) |

abrdn World Healthcare Fund |  | Kathleen Goetz (Class A Trustee, 3 year term ending 2028) Christian Pittard (Class A Trustee, 3 year term ending 2028) |

Each nominee has indicated an intention to serve as Trustee if elected and has consented to be named in this Joint Proxy Statement.

It is the intention of the persons named as proxies on the enclosed Proxy Card(s) to vote "FOR" the election of the nominees for each Class of Trustee to serve for a three-year term. In the event that a nominee is unable to serve for any reason when the election occurs, the proxies received will be voted for such substituted nominees as such Board may recommend.

ADDITIONAL INFORMATION ABOUT THE TRUSTEES

The Boards believe that each Trustee's experience, qualifications, attributes and skills on an individual basis and in combination with those of other Trustees lead to the conclusion that each Trustee should serve in such capacity. Among the attributes or skills common to all Trustees are their ability to review critically and to evaluate, question and discuss information provided to them, to interact effectively with the other Trustees, the Fund's investment adviser, the administrator and other service providers, counsel and independent registered public accounting firm, and to exercise effective and independent business judgment in the performance of their duties as Trustees. Each Trustee's ability to perform the duties of a trustee effectively has been attained and enhanced through the Trustee's education, professional training and other life experiences, such as business, consulting or public service positions and through experience from service as a member of each Fund's Board, public companies, or non- profit entities or other organizations.

(2) "Family of Investment Companies" means those registered investment companies that are advised by the Investment Adviser, or an affiliate of the Investment Adviser, and that hold themselves out to investors as related companies for purposes of investment and investor services.

As of April 1, 2025, each Fund's Trustees and officers, in the aggregate, owned less than 1% of that Fund's outstanding equity securities. As of April 1, 2025, none of the Independent Trustees or their immediate family members owned any shares of the Investment Adviser or of any person (other than a registered investment company) directly or indirectly controlling, controlled by, or under common control with the Investment Adviser.

Mr. Goodson and Ms. Ferrari serve as executive officers of the Funds. As of April 1, 2025, Mr. Goodson owned between $1 — $10,000 of HQH. As of April 1, 2025, Ms. Ferrari did not own shares of the Funds.

BOARD AND COMMITTEE STRUCTURE

The Board of each Fund is comprised of six individuals, five of whom are not "interested persons" of the Fund as defined in the Investment Company Act of 1940, as amended (the "1940 Act") ("Independent Trustees"). Each Fund divides the Board into three classes, with each class having a term of three years. Each year, the term of office of one class will expire and the successor(s) elected to such class will serve for a three-year term.

Each Board has appointed Mr. Reit, an Independent Trustee, as Chair. The Chair presides at meetings of the Trustees, participates in the preparation of the agenda for meetings of the Board, and acts as a liaison between the Trustees and management between Board meetings. Except for any duties specified herein, the designation as Chair does not impose on such Trustee any duties, obligations or liability that is greater than the duties, obligations or liability imposed on such person as a member of a Board, generally.

12

The Board of each Fund holds regular quarterly meetings to consider and address matters involving the respective Fund. Each Board also may hold special meetings to address matters arising between regular meetings. The Independent Trustees also meet outside the presence of management in executive session and have engaged separate, independent legal counsel to assist them in performing their oversight responsibilities.

The Board of each Fund has established a committee structure that includes an Audit Committee, Nominating and Corporate Governance Committee and Private Venture Valuation Committee (each discussed in more detail below) to assist each Board in the oversight and direction of the business affairs of the respective Fund. All of the members of these Committees are Independent Trustees. Each Board may also designate working groups or ad hoc committees as it deems appropriate.

The Board of each Fund has determined that its leadership structure is appropriate for the Fund because it enables the Board to exercise informed and independent judgment over matters under its purview, allocates responsibility among committees in a manner that fosters effective oversight and allows the Board to devote appropriate resources to specific issues in a flexible manner as they arise. The Board periodically reviews its leadership structure as well as its overall structure, composition, and functioning and may make changes at its discretion at any time.

Audit Committee

Each Fund has an Audit Committee comprised solely of Independent Trustees who are "independent" as defined in the New York Stock Exchange ("NYSE") Listing Standards. The Board of each Fund has adopted a written charter for the Audit Committee. The Audit Committee charter of the Funds is available at www.abrdnhqh.com, www.abrdnhql.com, www.abrdnthq.com and www.abrdnthw.com. The principal purpose of each Fund's Audit Committee is to assist the Board in fulfilling its responsibility to oversee the integrity of the Fund's financial statements and the Fund's compliance with legal and regulatory requirements (including related tax requirements) and to oversee management's conduct of the Fund's financial reporting process, including reviewing the financial reports and other financial information provided by the Fund, the Fund's systems of internal accounting and financial controls and the annual independent audit process. Each Audit Committee is responsible for the selection and engagement of the respective Fund's independent registered public accounting firm (subject to ratification by the Fund's Independent Trustees).

Each Audit Committee's role is one of oversight, and it is recognized that each Fund's officers are responsible for preparing each Fund's financial statements and that each Fund's independent registered public accountant is responsible for auditing those financial statements. Although each Audit Committee member must be financially literate and one member must have accounting or financial management expertise (as determined by the Board in its business judgment), Audit Committee members are not professionally engaged in the practice of accounting or auditing and are not experts in the fields of accounting or auditing, including with respect to auditor independence. Audit Committee members rely, without independent verification, on the information provided to them and on the representations made by management and each Fund's independent registered public accountants.

The members of each Fund's Audit Committee are Mr. Bailey, Ms. DiMartino, Ms. Goetz, Mr. Maher and Mr. Reit. Mr. Maher is the Chair of each Fund's Audit Committee and the Board has determined that Mr. Maher is an "audit company financial expert" as defined by Section 401(h) of Regulation S-K.

Nominating and Corporate Governance Committee

Each Fund has a Nominating and Corporate Governance Committee ("Nominating Committee") to promote the effective participation of qualified individuals on the Board, committees of the Board, and to review, evaluate and enhance the effectiveness of the Board in its role in governing the Fund and overseeing the management

13

of the Fund so that the interests of shareholders of the Fund are well-served. In pursuit of this purpose, the Nominating Committee's responsibilities include the identification and nomination of new Trustees and the coordination of the annual self-assessment of the performance of the Board and the Fund's committee structure to ensure the effective functioning of each Board. The members of each Fund's Committee are Mr. Bailey, Ms. DiMartino, Ms. Goetz, Mr. Maher and Mr. Reit. Mr. Reit is the Chair of the Committee.

Each Nominating Committee makes nominations to fill vacancies for trustees of the Fund and submits such nominations to the full Board. No trustee may be elected by the Board or nominated by the Board for election by shareholders unless nominated by the Committee. In nominating candidates, each Nominating Committee will seek to identify candidates who can bring to the Board the skills, experience and judgment necessary to address the issues trustees of investment companies, and the Fund in particular, may confront in fulfilling their duties to fund shareholders. The Nominating Committees may, in their discretion, establish specific, minimum qualifications (including skills) that must be met by candidates and may take into account a wide variety of factors in considering prospective trustee candidates. The Nominating Committees generally consider the background, experience, qualifications, attributes, skills and diversity that a prospective trustee will bring to the Board. The Nominating Committees may also consider other factors or attributes as they may determine appropriate in their judgment. Each Nominating Committee believes that the significance of each candidate's background, experience, qualifications, attributes or skills must be considered in the context of the Board as a whole.

The Nominating Committees shall consider Trustee candidates from such sources it deems appropriate, including candidates recommended by shareholders of a Fund. In order for a Nominating Committee to consider shareholder recommendations, the candidate must (i) satisfy any minimum qualifications of the Fund for its trustees, including all qualifications provided under the Nominating Committee's Charter and in the Fund's organizational documents; (ii) not be an "interested persons" of the Fund as that term is defined in the 1940 Act; and (iii) must be "independent" as defined in the NYSE listing standards.

Each Fund's By-Laws require that each prospective trustee candidate have substantial expertise, experience or relationships relevant to the business of the Fund and a college degree or equivalent business experience. Each Fund's By-Laws also provide that a prospective trustee candidate shall not serve as a director, trustee, officer, partner or employee of another investment company (as defined in the 1940 Act) that focuses its investments in the healthcare and/or life sciences industries, unless such investment company is managed by the Adviser or an affiliate thereof, or as a director, officer, partner or employee of the investment adviser, sponsor or equivalent of such an investment company with supervisory responsibility for the day-to-day operations of such investment company or investment decisions made with respect to such investment company.

All shareholder recommendations must be submitted in writing to the Secretary of the Fund by the deadline for submission of any shareholder proposals which would be included in the Fund's proxy statement for the next annual meeting of the Fund. Each shareholder or shareholder groups submitting proposed candidates must meet the requirements stated in the Nominating Committee's charter and in the Fund's organizational documents in order to recommend a candidate. The Committee will make such determinations in its sole discretion and such determinations shall be final.

The Nominating and Corporate Governance Committee charter of the Funds is available at www.abrdnhqh.com, www.abrdnhql.com, www.abrdnthq.com and www.abrdnthw.com.

Prior to the change in the Funds' investment adviser in October 2023, the Nominating and Corporate Governance Committee was referred to as the "Governance and Nominating Committee".

Private Venture Valuation Committee. Each to the Fund's Private Venture Valuation Committee general responsibility for determining, subject to Board ratification, in accordance with the Fund's valuation procedures, the value of the "start-up", early and/or later stage financing of a privately held company, securities (referred to as "Venture Capital Securities") held by the Fund. With respect to Venture Capital Securities for the Fund, the Private Venture Valuation Committee ("PV Valuation Committee"), has general responsibility for determining, subject to Board review, in accordance with the Fund's Valuation Procedures, the value of the Venture Capital Securities and Milestone Holdings held by the Fund on any day on which the net asset value per share is determined ("Valuation Date"). The PV Valuation Committee shall meet as often as necessary to ensure that prices are updated in a timely manner. No less than quarterly, the PV Valuation Committee will meet to review and/or update pricing in connection with the Venture Capital Securities and/or milestone holdings.

The members of each Fund's PV Valuation Committee are Mr. Bailey, Ms. Goetz and Mr. Maher. Mr. Bailey is the Chair of the Fund's PV Valuation Committee. Prior to the change in each Fund's investment adviser in October 2023, the PV Valuation Committee was referred to as the "Valuation Committee".

Board and Committee Meetings in Fiscal Year 2024

During the fiscal year ended September 30, 2024, HQH, THQ and THW's Boards each held eight meetings and HQL's Board held nine meetings; each Fund's Audit Committee held three meetings; each Fund's Nominating and Corporate Governance Committee held one meeting; and each Fund's PV Valuation Committee held four meetings.

Each of the incumbent Trustees attended at least 75% of the aggregate number of meetings of the Committees of the Board of each Fund on which such Trustee served during the period that he or she has served.

Board Oversight of Risk Management

Each Fund is subject to a number of risks including investment, compliance, operational and valuation risks. Although the Adviser and the officers of each Fund are responsible for managing these risks on a day-to-day basis, the Board of each Fund has adopted, and periodically reviews, policies and procedures designed to address these risks. As part of its regular oversight, the Board of each Fund, directly or through a Committee, interacts with the Fund's Chief Compliance Officer, the Fund's independent public accounting firm and the Fund's legal counsel. These interactions include discussing the Fund's risk management and controls with the independent registered public accounting firm engaged by the Fund, reviewing valuation policies and procedures and the valuations of specific restricted securities, and receiving periodic reports from the Fund's Chief Compliance Officer regarding compliance matters relating to the Fund and its major service providers, including results of the implementation and testing of the Fund's and such providers' compliance programs. The Board's oversight function is facilitated by management reporting processes designed to provide information to the Board regarding the identification, assessment, and management of critical risks and the controls and policies and procedures used to mitigate those risks. The Board reviews its role in supervising the Fund's risk management from time to time and may change the manner in which it fulfills its oversight responsibilities at its discretion at any time.

REPORTS OF THE AUDIT COMMITTEES; INFORMATION REGARDING THE FUNDS' INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

At a meeting held on December 11, 2024, the Board of each Fund, including a majority of the Trustees who are not "interested persons," as defined under the 1940 Act, selected KPMG LLP ("KPMG") to act as the independent registered public accounting firm for each Fund for the fiscal year ending September 30, 2025. Representatives from KPMG are not expected to be present at the Meetings to make a statement or respond to questions from shareholders. If requested by any shareholder by two (2) business days before the Meetings, a representative of KPMG will be present by telephone at the Meetings to respond to appropriate questions and will have an opportunity to make a statement if he or she chooses to do so.

Each Fund's financial statements for the fiscal year ended September 30, 2024 were audited by KPMG. The Audit Committee of each Fund has reviewed and discussed the audited financial statements of the Fund with management of the Fund. The Audit Committee of each Fund has received the written disclosures and the letter from KPMG required by The Public Company Accounting Oversight Board ("PCAOB") Rule 3526 (PCAOB Rule 1, Communication with Audit Committees Concerning Independence), as may be modified or supplemented, and have discussed with KPMG its independence with respect to the Fund. The Funds know of no direct financial or material indirect financial interest of KPMG in the Funds. The Audit Committees have discussed with KPMG the matters required to be discussed by the applicable requirements of the PCAOB and the SEC. Based on the foregoing review and discussions, the Audit Committee of each Fund recommended to the respective Board that the audited financial statements of each Fund for the fiscal year ended September 30, 2024 be included in each Fund's most recent annual report filed with the SEC.

All of the services described in the table above were pre-approved by the relevant Audit Committee.

Each Audit Committee has adopted an Audit Committee Charter that provides that the Audit Committee shall appoint, retain, and oversee an independent auditor and evaluate the terms of the engagement (including compensation

16

of the auditor) and the qualifications and independence of the independent auditor, including whether the independent auditor provides any consulting, auditing or tax services to the Investment Adviser (as defined below), and receive the independent auditor's specific representations as to its independence, delineating all relationships between the independent auditor and the Fund, consistent with the Independent Standards Board ("ISB") Standard No. 1. Each Audit Committee Charter also provides that the Committee shall review in advance, and consider approval of, any and all proposals by Fund management or the Investment Adviser that the Fund, Investment Adviser or their affiliated persons to employ the independent auditor to render "permissible non-audit services" to the Fund and to consider whether such services are consistent with the independent auditor's independence.

Each Audit Committee has considered whether the provision of non-audit services that were rendered to the investment adviser that managed the Funds during the fiscal years ended September 30, 2023 and September 30, 2024, and any entity controlling, controlled by, or under common control with any Covered Service Provider that provides ongoing services to the Funds that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X, is compatible with maintaining the independent auditor's independence and has concluded that it is independent.

EQ Fund Solutions, LLC ("EQ") has been retained to assist in the solicitation of proxies and will receive an estimated fee of $2,500 per Fund and be reimbursed for its reasonable expenses, which are estimated to be $825-$1,350 for each Fund.

18

Solicitation and Voting of Proxies. Solicitation of proxies is being made primarily by the mailing of this Joint Proxy Statement with its enclosures on or about April 14, 2025. As mentioned above, EQ has been engaged to assist in the solicitation of proxies. As the date of the Meetings approach, certain shareholders of a Fund may receive a call from a representative of EQ, if the Fund has not yet received their vote. Authorization to permit EQ to execute proxies may be obtained by telephonic instructions from shareholders of a Fund. Proxies that are obtained telephonically will be recorded in accordance with procedures that management of each of the Funds believes are reasonably designed to ensure that the identity of the shareholder casting the vote is accurately determined and that the voting instructions of the shareholder are accurately determined.

Beneficial Owners. Based upon filings made with the SEC, as of April 1, 2025, the following table shows certain information concerning persons who may be deemed beneficial owners of 5% or more of the shares of the Funds because they possessed or shared voting or investment power with respect to a Fund's shares:

Fund |  | Class |  | Name and Address |  | Number of Shares Beneficially Owned |  | Percentage of Shares |
HQL |  | Common Stock |  | Saba Capital Management, L.P.* Saba Capital Management GP, LP* Boaz R. Weinstein* 405 Lexington Avenue 58th Floor New York, NY 10174 |  |  | 3,188,405 |  |  |  | 11.36 | % |

* These entities jointly filed a Schedule 13D for the share amount and percentage shown.

Shareholder Proposals.

Any Rule 14a-8 shareholder proposal to be considered for inclusion in the Funds' proxy statement and form of proxy for the annual meetings of shareholders to be held in 2026 should be received by the Secretary of the Funds no later than December 15, 2025. There are additional requirements regarding proposals of shareholders, and a shareholder contemplating submission of a proposal for inclusion in the Funds' proxy materials is referred to Rule 14a-8 under the 1934 Act.

In addition, shareholder proposals for each Fund's 2025 Annual Meeting (other than proposals submitted for inclusion in the Fund's 2026 proxy statement pursuant to Rule 14a-8) must be submitted to the Fund's Secretary between January 28, 2026 and February 27, 2026, unless the meeting date is more than 30 days before or after May 28, 2026, in which case the proposal must be submitted by the later of the close of business on (1) the date 90 days prior to the 2026 Annual Meeting date or (2) the tenth business day following the date on which the 2026 Annual Meeting date is first publicly announced or disclosed.

In accordance with Rule 14a-4(c), each Fund may exercise discretionary voting authority with respect to any shareholder proposals for the Annual Meetings not included in the proxy statement and form of proxy card which are not submitted to the Funds within the time-frame indicated above. Even if timely notice is received, a Fund may exercise discretionary voting authority in certain other circumstances permitted by Rule 14a-4(c) and SEC guidance related thereto. Discretionary voting authority is the ability to vote proxies that shareholders have executed and returned to a Fund on matters not specifically reflected on the form of proxy card.

SHAREHOLDERS WHO DO NOT EXPECT TO ATTEND THE MEETINGS AND WHO WISH TO HAVE THEIR SHARES VOTED ARE REQUESTED TO DATE AND SIGN THE ENCLOSED PROXY CARD(S) AND RETURN THEM IN THE ENCLOSED ENVELOPE. NO POSTAGE IS REQUIRED IF MAILED IN THE UNITED STATES.
