Item 8.01 Other Events.

Quantum Corporation (the “Company”) has established December 16, 2025 as the date for its 2025 annual meeting of stockholders (the “Annual Meeting”).

A stockholder proposal not included in the proxy statement for the Annual Meeting will not be eligible for presentation at the meeting unless the stockholder gives timely notice of the proposal in writing to the Company’s Secretary at its principal executive offices and otherwise complies with the provisions of the Company’s Amended and Restated Bylaws (the “Bylaws”). To be timely, the Bylaws provide that the Company must have received the stockholder’s notice not later than the 45th day nor earlier than the 75th day before the one-year anniversary of the date on which the Company first mailed its proxy materials or a notice of availability of proxy materials (whichever is earlier) for the preceding year’s annual meeting of stockholders. However, because the date of the Annual Meeting is delayed by more than 60 days after the one-year anniversary of the 2024 annual meeting, the Company must receive the stockholder’s notice not earlier than the close of business on the 120th day before the Annual Meeting and not later than the close of business on the later of (i) the 90th day before the Annual Meeting, and (ii) the tenth day after public announcement of the Annual Meeting date. For the Annual Meeting, stockholders must submit written notice to the Secretary in accordance with the Bylaws no later than the close of business on October 30, 2025.

In addition to complying with the October 30, 2025 deadline, stockholder proposals intended to be considered for inclusion in the Company’s proxy materials and director nominations for the Annual Meeting must also comply with all applicable Securities and Exchange Commission rules, including Rule 14a-8 and Rule 14a-19, Delaware corporate law, and the Bylaws in order to be eligible for inclusion in the proxy materials for the Annual Meeting.
