Supplement dated September 13, 2024 to the Funds' Summary Prospectuses, Statutory Prospectus and Statement of Additional Information, each dated February 29, 2024, as supplemented to date

For all existing and prospective shareholders of abrdn Focused U.S. Small Cap Equity Fund and abrdn Emerging Markets Dividend Fund:

• The abrdn Focused U.S. Small Cap Equity Fund and abrdn Emerging Markets Dividend Fund will be converted from mutual funds to exchange-traded funds (the "ETFs"), which is expected to occur on or around February 14, 2025.

• If you are an existing shareholder of a Fund, and your account can hold an ETF, your fund shares will be converted, and no action is needed by you.

• If you hold shares of a Fund in an account that cannot hold an ETF (i.e., your account is not permitted to purchase securities traded in the stock market), there are certain actions you can take. See the "Questions and Answers" section below for further information.

At a meeting held on September 11, 2024, the Board of Trustees (the "Board") of the Trust approved, on behalf of each Fund, the conversion of each Fund into an ETF (each, a "Conversion"), which will continue to be managed by abrdn Inc. ("abrdn"), the investment adviser for the Funds, and, as applicable, abrdn Investments Limited, the sub-adviser for the abrdn Emerging Markets Dividend Fund. The Board, including all of the Trustees who are not "interested persons" (as defined in the Investment Company Act of 1940, as amended (the "1940 Act")) of the Trust, determined that participation in the Conversions is in the best interests of each Fund and that the interests of existing shareholders of the Funds will not be diluted as a result of the Conversions.

Subject to making various filings with the U.S. Securities and Exchange Commission (the "SEC"), the Funds will be reorganized into newly created ETFs listed below, each of which will be a series of the Trust:

Current Fund		Proposed ETF
abrdn Focused U.S. Small Cap Equity Fund		abrdn Focused U.S. Small Cap Active ETF
abrdn Emerging Markets Dividend Fund		abrdn Emerging Markets Dividend Active ETF

Each new ETF will be managed in the same manner as the corresponding Fund, with no changes to the investment objectives, strategies and fundamental investment restrictions and will be managed by the same portfolio managers (except for the addition of Awais Khan as a portfolio manager of each ETF).

By converting these Funds to ETFs, abrdn believes shareholders in the Funds could benefit from lower overall net expenses, additional trading flexibility, increased portfolio holdings transparency and the potential for enhanced tax efficiency.

Each Conversion will be conducted pursuant to an Agreement and Plan of Reorganization and Liquidation (each a "Plan"). Each Conversion is structured to be a tax-free reorganization under the U.S. Internal Revenue Code of 1986, as amended. As a result, Fund shareholders generally will not recognize a taxable gain (or loss) for U.S. tax purposes as a result of the Conversion (although cash received as part of a Conversion may be taxable, as noted below).

In connection with each Conversion, shareholders of the Fund will receive shares in the corresponding ETF equal in value to the number of shares of the Fund they own and may receive a cash payment in lieu of fractional shares of the corresponding ETF, and the redemption of fractional shares may be a taxable event.

Importantly, in order to receive shares of an ETF as part of a Conversion, Fund shareholders must hold their shares of a Fund through a brokerage account that can accept shares of an ETF. If Fund shareholders do not hold their shares of a Fund through that type of brokerage account, they will not receive shares of an ETF as part of a Conversion and will receive cash equal in value to the NAV of their mutual fund shares. For Fund shareholders that do not currently hold their shares of a Fund through a brokerage account that can hold shares of an ETF, please see the Q&A that follows for additional actions that those Fund shareholders must take in order to receive shares of an ETF as part of a Conversion. No further action is required for Fund shareholders that hold shares of a Fund through a brokerage account that can hold shares of an ETF.

Completion of the Conversions is subject to a number of conditions under the Plans. It is anticipated that each Conversion will not require shareholder approval. Fund shareholders will receive, on or around October 30, 2024, an information statement/prospectus describing in detail both the Conversions and the ETFs, and a summary of the Board's considerations in approving the Conversions.

In anticipation of the Conversions, purchases, including exchange purchases, by existing shareholders will be accepted by the Funds until February 12, 2025. Redemptions, including exchange redemptions, into shares of another fund of the Trust will be accepted until February 13, 2025. These dates may change if the closing date of the Conversions changes.

In addition, as part of the Conversions, the following preliminary events will occur before the Conversions are completed:

• On or around October 18, 2024, all issued and outstanding Class A, Class R and Institutional Service Class shares of the abrdn Focused U.S. Small Cap Fund and all issued and outstanding Class A shares of the abrdn Emerging Markets Dividend Fund will be converted to Institutional Class shares of the respective Fund effective after the close of business on October 18, 2024 (the "Share Class Consolidation"); and

• On or around February 7, 2025, when the abrdn Focused U.S. Small Cap Equity Fund has only Institutional Class shares outstanding, those outstanding shares will be combined into fewer shares through a reverse stock split (the "Reverse Stock Split").

At a meeting held on September 11, 2024, the Board of the Trust approved the Share Class Consolidation on behalf of each Fund and the Reverse Stock Split on behalf of the abrdn Focused U.S. Small Cap Equity Fund.

The Share Class Consolidation is intended to move shareholders into a share class that most closely resembles the ETF share class structure. The Funds have adopted a Rule 12b-1 Plan for Class A and Class R shares (as applicable) under which the Funds compensate the Funds' distributor for expenses associated with distribution-related and/or shareholder services, whereas abrdn does not expect the New ETFs to adopt a Rule 12b-1 Plan or pay 12b-1 fees pursuant to a 12b-1 plan. Institutional Class shares most closely resemble the ETF share class structure due to the lack of 12b-1 fees. Institutional Class shares of each Fund have lower gross and net total expense ratios than Class A, Class R and Institutional Service Class shares, as applicable. The Share Class Consolidation would be effected on the basis of the relative net asset values of the two relevant classes, without the imposition of any sales load, fee or other charge.

Suspension of Sales. Effective after market close on September 20, 2024, shares of the Funds will no longer be available for purchase by investors with the exception of: (1) existing shareholders

(including shares acquired through the reinvestment of dividends and distributions); (2) employer sponsored retirement plans; or (3) fee-based programs sponsored by financial intermediaries that have selected the Funds prior to market close on September 20, 2024.

Prior to the Conversion but following the Share Class Consolidation, the Institutional Class shares of the abrdn Focused U.S. Small Cap Equity Fund will combine into fewer shares through the Reverse Stock Split to increase the net asset value per share of the Institutional Class. The Reverse Stock Split will occur at an exact ratio to be determined by abrdn Inc., as the investment adviser to the Fund, which is currently expected to be between 1-for-3 to 1-for-6. If, for example, the exact ratio is 1-for-6, a shareholder would receive one Institutional Class share for every six Institutional Class shares held. As with the Share Class Consolidation, the total net asset value of each shareholder's Institutional Class shares will be the same after the reverse split as before the reverse split. The Reverse Stock Split will not result in a taxable transaction for shareholders.

Effective September 13, 2024:

• Rule 12b-1 fees on all applicable share classes for the Funds will be waived.

• No sales charge or contingent deferred sales charge will be imposed on purchases or redemptions (as applicable) of all applicable share classes of the Funds.

• Any current Letter of Intent under which applicable shares of the Funds were purchased are considered completed.

IMPORTANT NOTICE ABOUT YOUR FUND ACCOUNT
QUESTIONS AND ANSWERS

The following is a brief Q&A that provides information to help you to determine whether you need to take action with respect to your shareholder account before the Conversions in order to receive shares of the ETFs.

Q. Why is abrdn converting my Fund to an ETF?

A. abrdn and the Board of Trustees of the Trust believe that the Conversions will provide multiple benefits for investors of the Funds, including lower net expenses, additional trading flexibility, increased portfolio holdings transparency and the potential for enhanced tax efficiency.

Q. How will the ETFs be managed after the change?

A. The ETFs will be managed in the same manner as the Funds, with no changes to the investment objectives, strategies and fundamental investment restrictions and will be managed by the same portfolio managers (except for the addition of Awais Khan as a portfolio manager of the ETFs).

Q. What types of shareholder accounts can receive shares of an ETF as part of the Conversions?

A. If you hold your Fund shares in an account that permits you to purchase securities traded on U.S. stock exchanges, such as ETFs or other types of stocks, then you will be eligible to receive shares of an ETF in the Conversion. No further action is needed by you.

Q. What types of shareholder accounts cannot receive shares of an ETF as part of the Reorganization?

A. The following account types cannot hold ETFs:

• Non-Accommodating Brokerage Accounts. If you hold your Fund shares in an account with a financial intermediary that only allows you to hold shares of mutual funds in the account, you will need to contact your broker or financial intermediary to transfer your shares to an existing or new brokerage account that permits investment in ETF shares. If you do nothing, you will not receive shares of the ETF, your position will be liquidated at the time of Conversion and you will receive a cash distribution equal in value to the NAV of your Fund shares less any fees and expenses your intermediary may charge. This event may be taxable to you. To prevent a taxable event, please contact your broker or financial intermediary to transfer your shares to an existing or new brokerage account.

• Non-Accommodating Retirement Accounts. If you hold your Fund shares through an IRA or group retirement plan whose plan sponsor does not have the ability to hold shares of ETFs on its platform, you may need to redeem your shares prior to the applicable Conversion, or your broker or intermediary may transfer your investment in the Fund to a different investment option before or at the time of the Conversion.

• Fund Direct Accounts. If you hold your Fund shares in an account directly with the Fund's transfer agent, SS&C GIDS, Inc. (including a Fund Direct IRA or Coverdell Savings Account), you should: (i) transfer your Fund shares to a brokerage account that can accept ETF shares prior to the Conversion, (ii) exchange your Fund shares for shares in another fund of the Trust, or (iii) for a Fund Direct IRA or Coverdell Savings Account, transfer your investment to a different institution prior to the Conversion. If such a change is not made before the time of the Conversion, you will not receive shares of the ETF and your position will be liquidated at the time of Conversion and you will receive a cash distribution equal in value to the NAV of your Fund shares. This event may be taxable.

If you are unsure about the ability of your account to accept shares of an ETF, please contact your broker or financial intermediary.

Q. How do I transfer my Fund shares from a fund direct account to a brokerage account that will accept ETF shares?

A. Transferring your shares from a fund direct account to a brokerage account that can accept shares of an ETF should be a simple process. If you have a brokerage account or a relationship with a brokerage firm, please talk to your broker and inform the broker that you would like to transfer a mutual fund position that you hold directly with a Fund into your brokerage account. Also inform your broker that such an account will need to be set up to accept shares of an ETF. If you don't have a brokerage account or a relationship with a brokerage firm, you will need to open an account.

We suggest you provide your broker with a copy of your quarterly statement from the Fund. Your broker will require your account number with the Fund, which can be found on your statement. Your broker will help you complete a form to initiate the transfer. Once you sign that form, your broker will submit the form to the Funds' transfer agent directly, and the shares will be transferred into your brokerage account. The sooner you initiate the transfer, the better.

Q. How do I transfer my Fund shares from a non-accommodating brokerage account to a brokerage account that will accept ETF shares?

A. The broker where you hold your Fund shares should be able to assist you in changing the characteristics of your brokerage account to an account that is permitted to invest in ETF shares. Contact your broker right away to make the necessary changes to your account.

Q. What if I do not want to own shares of the ETF?

A. If you do not want to receive shares of an ETF in connection with the Conversion, you can exchange your Fund shares for shares of another mutual fund in the Trust or redeem your shares of the Fund. Before doing so, however, you should consider the tax consequences associated with either action. Exchanging or redeeming your Fund shares may be a taxable event. The last date for redemptions, including exchange redemptions, before the Conversion is February 13, 2025. This date may change if the closing date of the Conversion changes.
