Seelos Announces Postponement of its Annual Meeting of Stockholders

NEW YORK, September 26, 2024 /PRNewswire/ -- Seelos Therapeutics, Inc. (Nasdaq: SEEL) (“Seelos”), a clinical-stage biopharmaceutical company focused on the development of therapies for central nervous system disorders and rare diseases, today announced that its 2024 Annual Meeting of Stockholders (the “Annual Meeting”), which was originally scheduled to be held on September 27, 2024, has been postponed. The Annual Meeting is now scheduled to be held virtually, via live webcast at www.virtualshareholdermeeting.com/SEEL2024, on Friday, October 25, 2024 at 8:00 a.m., Eastern Time. The record date for the Annual Meeting August 19, 2024, is unchanged and applies to the postponed Annual Meeting.

The Annual Meeting has been postponed due to an anticipated lack of quorum, and to provide further time to solicit proxies from the Company’s stockholders. Seelos’ Board of Directors unanimously recommends that you vote FOR the Board of Director nominees and FOR all other proposals identified in the Company’s proxy statement for the Annual Meeting. Stockholders who have already cast their votes do not need to take any action, unless they wish to change or revoke their prior proxy or voting instructions, and their votes will be counted at the postponed Annual Meeting. For stockholders who have not yet cast their votes, we urge them to vote their shares now, so they can be tabulated prior to the postponed Annual Meeting.
