ABRDN GLOBAL INFRASTRUCTURE INCOME FUND ANNOUNCES ADJOURNMENT OF SPECIAL SHAREHOLDER MEETING RELATING TO PROPOSED ACQUISITION OF ASSETS OF MACQUARIE GLOBAL INFRASTRUCTURE TOTAL RETURN FUND INC.

(Philadelphia, November 9, 2022) – abrdn Global Infrastructure Income Fund (“ASGI” or the “Acquiring Fund”) adjourned its special meeting of shareholders (the “Meeting”) held on Wednesday, November 9, 2022 to Wednesday, November 23, 2022 at 11:00am eastern time to allow for the solicitation of additional proxies for the Meeting to achieve the requisite quorum.

The August 11, 2022 record date for shareholders entitled to vote at the Meeting remains unchanged. ASGI shareholders who have already voted do not need to take further action. abrdn encourages all shareholders of record of ASGI on August 11, 2022 who have not yet voted to do so as soon as possible.

The Meeting is to approve the issuance of additional common shares of beneficial interest of ASGI in connection with the reorganization of Macquarie Global Infrastructure Total Return Fund Inc. (“MGU”), which is advised by Delaware Management Company, with and into ASGI (the “Reorganization”). The proposed Reorganization is subject to the receipt of necessary shareholder approvals by each Fund. The stockholders of MGU approved the Reorganization at a special stockholder meeting held on November 9, 2022, subject to the approval of the share issuance proposal by shareholders of ASGI.

The combination of ASGI and MGU will help ensure the viability of the Funds, increasing scale, liquidity and marketability changes that may lead to a tighter discount or a premium to NAV over time. Following the Reorganization, shareholders of ASGI will experience an increase in the assets under management and a reduction in total expense ratio. There are no proposed changes to the current objectives or policies of ASGI as a result of the Reorganization, including ASGI’s monthly distribution policies and approach as to the use of leverage. ASGI’s Board of Trustees believes that the Reorganization is in the best interest of ASGI’s shareholders recognizing the strategic objective of creating scale for the benefit of shareholders.

It is currently expected that the Reorganization will be completed in the first quarter of 2023 subject to (i) approval by the ASGI shareholders of the issuance of shares in connection with the Reorganization, and (ii) the satisfaction of customary closing conditions.

Additional information regarding the Reorganization was presented in a proxy statement sent to ASGI’s shareholders.
