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 13, 2026 to shareholders of record as of April 1, 2026.

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 A Trustees to serve until the 2029 Annual Meeting of Shareholders or until such Trustee's successor is duly elected and qualified.

HQL — To elect two Class A Trustees to serve until the 2029 Annual Meeting of Shareholders or until such Trustee's successor is duly elected and qualified.

THQ — To elect two Class C Trustees to serve until the 2029 Annual Meeting of Shareholders or until such Trustee's successor is duly elected and qualified.

THW — To elect two Class B Trustees to serve until the 2029 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,

------

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 1, 2026 (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

------

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 1, 2026 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 | 57,192,236.00 |
| HQL | 30,408,047.00 |
| THQ | 41,437,474.70 |
| THW | 40,344,912.60 |

**Important Notice Regarding the Availability of Proxy Materials for the Meetings to Be Held on Wednesday, May 27, 2026: The Proxy Materials and each Fund's most recent annual report for the fiscal year ended September 30, 2025 are available on the Internet at http://www.aberdeenhqh.com (for HQH) http://www.aberdeenhql.com (for HQL) http://www.aberdeenthq.com (for THQ) and http://www.aberdeenthw.com (for THW). Each Fund will furnish, without charge, a copy of its annual report for the fiscal year ended September 30, 2025 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 A** | **Class B** | **Class B** | **Class C** | **Class C** |

| HQL |  | 2029 |  | 2027 |  | 2028 |
| THQ |  | 2027 |  | 2028 |  | 2029 |
| THW |  | 2028 |  | 2029 |  | 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.

------

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 | Christian Pittard (Class A Trustee, 3 year term ending 2029)<br>Jeffrey A. Bailey (Class A Trustee, 3 year term ending 2029) |
| abrdn Life Sciences Investors | C. William Maher (Class A Trustee, 3 year term ending 2029)<br>Kathleen Goetz (Class A Trustee, 3 year term ending 2029) |
| abrdn Healthcare Opportunities Fund | Christian Pittard (Class C Trustee, 3 year term ending 2029)<br>Jeffrey A. Bailey (Class C Trustee, 3 year term ending 2029) |
| abrdn World Healthcare Fund | Rose DiMartino (Class B Trustee, 3 year term ending 2029)<br>Todd Reit (Class B Trustee, 3 year term ending 2029) |

---

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.

**EACH FUND'S BOARD, INCLUDING THE INDEPENDENT TRUSTEES, RECOMMENDS THAT SHAREHOLDERS VOTE "FOR" EACH NOMINEE.**

The following tables set forth certain information regarding the nominees for election to the Boards of the Funds, Trustees whose terms of office continue beyond the Meetings, and the principal officers of the Funds. abrdn Inc., its parent company Aberdeen Group plc, and its advisory affiliates are collectively referred to as "Aberdeen" in the tables below.

**ADDITIONAL INFORMATION ABOUT THE TRUSTEES**

Each Board believes 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.

A Trustee's ability to perform his or her duties effectively may have been attained through the Trustee's executive, business, consulting, and/or legal positions; experience from service as a Trustee of the Fund(s) and other funds/portfolios in the Aberdeen fund complex, other investment funds, public companies, or non-profit entities or other organizations; educational background or professional training or practice; and/or other life experiences. In this regard, the following specific experience, qualifications, attributes and/or skills apply as to each Trustee in addition to the information set forth in the table above: Mr. Bailey, extensive operational, business development, transactional and board-level expertise from senior roles across public and private pharmaceutical, biotechnology and medical device companies; Ms. Goetz, expertise in commercialization, market strategy, organizational leadership and governance from senior roles across the pharmaceutical, biotechnology and medical technology sectors; Ms. DiMartino, experience as a law firm partner counselling registered investment companies and their advisers in all aspects of fund organization and operation for over 30 years; Mr. Maher, experience as an officer in the financial services industry, including his experience as a chief financial officer and chief executive officer; Mr. Reit, banking and asset management experience and experience as a board member; Mr. Pittard, his experience as head of closed-end funds for an affiliate of the Investment Adviser. Each Trustee also has experience as a trustee or director of other funds with the Aberdeen Fund Complex.

Each Board believes that the significance of each Trustee's experience, qualifications, attributes or skills is an individual matter (meaning that experience important for one Trustee may not have the same value for another) and that these factors are best evaluated at the Board level as a whole, with no single Trustee, or particular factor, being indicative of Board effectiveness. In its periodic self-assessment of the effectiveness of the Board, each Board considers the complementary individual skills and experience of the individual Trustees 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 respective Fund. References to the qualifications, attributes and skills of Trustees are presented pursuant to disclosure requirements of the Securities and Exchange Commission ("SEC") and do not constitute holding out a Board or any Trustee as having any special expertise or experience, and shall not impose any greater responsibility or liability on any such person or on a Board by reason thereof.

As of March 16, 2026, each Fund's Trustees and officers, in the aggregate, owned less than 1% of that Fund's outstanding equity securities. As of March 16, 2026, 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 March 16, 2026, Mr. Goodson owned between $1 — $10,000 of HQH. As of March 16, 2026, 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.

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, and Nominating and Corporate Governance 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 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 http://www.aberdeenhqh.com, http://www.aberdeenhql.com, http://www.aberdeenthq.com and http://www.aberdeenthw.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 committee financial expert" as defined by Section 401(h) of Regulation S-K.

*Nominating and Corporate Governance Committee*

Each Board 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 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 the 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, the 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 its 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 shall consider Trustee candidates from such sources it deems appropriate, including candidates recommended by shareholders of the Fund. In order for the 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.

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 Nominating and Corporate Governance Committee charter of each Fund is available at its respective website at http://www.aberdeenhqh.com, http://www.aberdeenhql.com, http://www.aberdeenthq.com and http://www.aberdeenthw.com

*Board and Committee Meetings in Fiscal Year 2025*

During the fiscal year ended September 30, 2025, HQH, HQL, THQ and THW's Boards each held five meetings; each Fund's Audit Committee held four meetings; and each Fund's Nominating and Corporate Governance Committee held one meeting.

Each of the incumbent Trustees attended at least 75% of the aggregate number of meetings of the Boards of each Fund during the period for which he or she served as a Trustee. 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, among others, investment, compliance, operational and valuation risks. Risk oversight forms part of each Board's general oversight of the respective Fund and is addressed as part of various Board and Committee activities. Each Board has adopted, and periodically reviews, policies and procedures designed to address these risks. Different processes, procedures and controls are employed with respect to different types of risks. Day-to-day risk management functions are subsumed within the responsibilities of the Funds' Investment Adviser, who carry out the Funds' investment management and business affairs and other service providers in connection with the services they provide to the Funds. The Investment Adviser and other service providers have their own, independent interest in risk management, and their policies and methods of risk management will depend on their functions and business models. As part of its regular oversight of each Fund, the respective Board, directly and/or through a Committee, interacts with and reviews reports from, among others, the Investment Adviser and Sub-Adviser (as applicable) and each Fund's other service providers (including the Funds' transfer agent), the Funds' Chief Compliance Officer, the Funds' independent registered public accounting firm, legal counsel to the Funds, including Counsel to the Independent Trustees, and internal auditors, as appropriate, relating to the operations of the Funds. Each Board also requires the Investment Adviser to report to the Board on other matters relating to risk management on a regular and as-needed basis. The Boards recognize that it may not be possible to identify all of the risks that may affect the Funds or to develop processes and controls to eliminate or mitigate their occurrence or effects. Each Board may, at any time and in its discretion, change the manner in which it conducts risk oversight.

Shareholders who wish to communicate with Board members with respect to matters relating to the Funds may address their written correspondence to the Boards as a whole or to individual Board members c/o abrdn Inc. at 1900 Market Street, Suite 200, Philadelphia, PA 19103, or via e-mail to the Trustee(s) c/o abrdn Inc. at Investor.Relations@aberdeenplc.com.

**Trustees Attendance at Annual Meetings of Shareholders**

The Funds have not established a policy with respect to Trustee attendance at annual meetings of shareholders. The prior year's annual meetings of shareholders were attended by three Trustees.

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

At a meeting held on December 9, 2025, 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, 2026. 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, 2025 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, 2025 be included in each Fund's most recent annual report filed with the SEC.

\* "Non-Audit Fees billed to Fund" for both fiscal years represent "Tax Fees" and "All Other Fees" billed to Funds in their respective amounts from the previous table.

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 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, 2024 and September 30, 2025, 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.

**Relationship of Trustees or Nominees with the Investment Adviser and Administrator**

abrdn Inc. serves as the investment adviser ("Investment Adviser") to each Fund pursuant to an advisory agreement dated as of October 27, 2023. The Investment Adviser is a Delaware corporation with its registered offices located at 1900 Market Street, Suite 200, Philadelphia, PA 19103. abrdn Inc. also provides administrative services to each Fund under the advisory agreement. The Investment Adviser is an indirect subsidiary of Aberdeen Group plc, which has its registered offices at 1 George Street, Edinburgh, EH2 2LL, Scotland. Mr. Pittard, a Trustee of the Funds, is employed by the Investment Adviser.

**Delinquent Section 16(a) Reports**

Section 16(a) of the 1934 Act and Section 30(h) of the 1940 Act, as applied to the Funds, require the Funds' officers and Trustees, certain officers and directors of the Investment Adviser, affiliates of the Investment Adviser, and persons who beneficially own more than 10% of the Funds' outstanding securities to electronically file reports of ownership of the Funds' securities and changes in such ownership with the SEC and the NYSE.

Based solely on each Fund's review of such forms filed on EDGAR or written representations from reporting persons that all reportable transactions were reported, to the knowledge of each Fund, during the fiscal year ended September 30, 2025, each Fund's officers, Trustees and greater than 10% owners timely filed all reports they were required to file under Section 16(a) except that due to an administrative oversight, a Form 3 filing for each of HQH, HQL, THQ and THW was submitted late for Kolotioloma Silue, an officer of the Fund.

------

**ADDITIONAL INFORMATION**

**Administrator.** State Street Bank & Trust Company, located at 1 Heritage Drive, 3rd Floor, North Quincy, MA 02171, serves as administrator to the Funds.

**Expenses.** The expense of preparation, printing and mailing of the enclosed proxy card and accompanying Notice and Joint Proxy Statement will be borne proportionately by each Fund. Each Fund will reimburse banks, brokers and others for their reasonable expenses in forwarding proxy solicitation material to the beneficial owners of the shares of each Fund. In order to obtain the necessary quorum at each Meeting, supplementary solicitation may be made by mail, telephone or personal interview. Such solicitation may be conducted by, among others, officers, Trustees and employees of the Funds, the Investment Adviser, abrdn Inc. or its affiliates.

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.

**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 13, 2026. 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 March 16, 2026, 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 <br>Beneficially Owned** | **Percentage of Shares** |
| HQL | Common Stock | First Trust Portfolios L.P.\*<br>First Trust Advisers L.P.\*<br>The Charger Corporation\*<br>120 East Liberty Drive, Suite 400<br>Wheaton, Illinois 60187 | 3021786 | 10.09% |

---

\* These entities jointly filed a Schedule 13G 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 2027 should be received by the Secretary of the Funds no later than 120 calendar days prior to April 13, 2027 (the first anniversary of the date of the release of this year's proxy statement). 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 2027 Annual Meeting (other than proposals submitted for inclusion in the Fund's 2027 proxy statement pursuant to Rule 14a-8) must be submitted to the Fund's

------

Secretary no less that ninety (90) days nor no more than one hundred twenty (120) days prior to the first anniversary date of each Fund's 2026 Annual Meeting (May 27, 2027), unless the meeting date is more than 30 days before or after May 27, 2027, 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 2027 Annual Meeting date or (2) the tenth business day following the date on which the 2027 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 timeframe 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.**

**Delivery of Joint Proxy Statement**

Unless the Funds have received contrary instructions from shareholders, only one copy of this Joint Proxy Statement may be mailed to households, even if more than one person in a household is a shareholder of record. If a shareholder needs an additional copy of this Joint Proxy Statement, please contact the Funds at 1-800-522-5465. If any shareholder does not want the mailing of this Joint Proxy Statement to be combined with those for other members of its household, please contact the Funds in writing at: 1900 Market Street, Suite 200, Philadelphia, PA 19103 or call the Funds at 1-800-522-5465.
