Notice of 2026 Annual Meeting Date and Related Deadlines

As of the date of this Annual Report, we intend to hold our 2026 annual meeting of stockholders (the “2026 Annual Meeting”) on or about June 16, 2026. This date is more than 30 days before the one-year anniversary of our 2025 annual meeting of stockholders (the “2025 Annual Meeting”), which was held on August 27, 2025.

Our bylaws provide that for stockholder nominations to our board of directors or other proposals to be considered at an annual meeting of stockholders, the stockholder must give timely notice thereof in writing to the Corporate Secretary at Genelux Corporation, 2625 Townsgate Road, Suite 230, Westlake Village, CA 91361.

Because the date of the 2026 Annual Meeting is more than 30 days before the one-year anniversary of the date of our 2025 Annual Meeting, for the stockholder notice to be timely, it must be delivered to the Corporate Secretary at our principal executive offices not earlier than 5:00 p.m. Pacific Time on the 120th day prior to the date of the 2026 Annual Meeting, February 16, 2026, and not later than 5:00 p.m. Pacific Time on the later of (1) the 90th day prior to the 2026 Annual Meeting, March 18, 2026, or (2) the close of business on the tenth day following the day on which public announcement of the date of such meeting is first made by us, March 29, 2026. A stockholder’s notice to the Corporate Secretary must set forth as to each matter the stockholder proposes to bring before the 2026 Annual Meeting the information required by applicable law and our bylaws.

In addition, stockholder proposals submitted pursuant to Rule 14a-8 under the Exchange Act and intended to be presented at our 2026 Annual Meeting must be received by us a reasonable time before we mail our proxy materials for the 2026 Annual Meeting. We have determined that March 16, 2026, which is the date disclosed in our definitive proxy statement on Schedule 14A for our 2025 Annual Meeting, remains a reasonable time before we expect to mail our proxy materials for the 2026 Annual Meeting, and that any stockholder proposals must be received on or before the close of business on that date in order to be considered for inclusion in our proxy materials for the 2026 Annual Meeting. A stockholder’s notice to the Corporate Secretary must set forth as to each matter the stockholder proposes to bring before the 2026 Annual Meeting, the information required by applicable law and our bylaws.

In addition, stockholders who intend to solicit proxies in support of director nominees other than our nominees must provide in their notice any additional information required by Rule 14a-19(b) under the Exchange Act.
