Item 8.01 Other Events.

On July 22, 2026, Ares Strategic Income Fund (the “Fund”) reconvened its 2026 Annual Meeting of Shareholders (the “2026 Annual Meeting”), previously adjourned on June 24, 2026. Quorum for the 2026 Annual Meeting requires holders of 50% of the outstanding shares of the Fund (without regard to class or series) entitled to vote to be present, in person or by proxy. A quorum was not present, so the chairperson of the 2026 Annual Meeting adjourned the meeting without (i) voting upon the election of trustee nominees, or (ii) ratifying the appointment of KPMG LLP as the Fund’s independent registered public accounting firm for the year ending December 31, 2026. The Fund does not expect to reconvene the 2026 Annual Meeting and intends to hold its next annual meeting of shareholders in 2027 (the “2027 Annual Meeting”).

The Fund’s current board of trustees will continue to serve until the earlier of the 2027 Annual Meeting or the date, if any, on which their successors are duly elected and qualify. In addition, the ratification by shareholders of KPMG LLP as the Fund’s independent registered public accounting firm for the year ending December 31, 2026 is not required for their appointment and they will serve in that capacity at the direction of the Fund’s audit committee.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
