Additional Information About the Acquisition and Where To Find It

The Company has filed a preliminary proxy statement with the SEC in connection with the proposed acquisition (the “Acquisition”) of Dogehash Technologies, Inc. (“Dogehash”) and plans to submit and mail a definitive proxy statement and other relevant documents to the Company’s stockholders. The closing of the Acquisition is conditioned upon the Company obtaining the required stockholder approvals, approval from The Nasdaq Stock Market LLC, and customary closing conditions.

The Company’s stockholders and other interested persons are advised to read, when available, the definitive proxy statement, and amendments thereto, and the other relevant documents filed with the SEC in connection with the Company’s solicitation of proxies for its stockholders’ annual meeting to be held to approve, among other things, the Acquisition because the proxy statement will contain important information about the Company, Dogehash and the transactions contemplated thereby. The definitive proxy statement will be mailed to stockholders of the Company as of a record date to be established for voting on the transactions. Investors may obtain a free copy of the definitive proxy statement (if and when it becomes available) and other relevant documents filed by the Company with the SEC at the SEC’s website at www.sec.gov. Stockholders of the Company will also be able to obtain copies of the definitive proxy statement, without charge, once available, at the SEC’s website at www.sec.gov or by directing a request to: Thumzup Media Corporation, 10557-B Jefferson Blvd., Los Angeles, CA 90232, Attention: Investor Relations.
