GeoVax names Tyler O'Brien interim CEO and board chairman, effective November 8, 2026
The appointment follows the November 5 firing of David Dodd and the addition of new director Shahin Behroyan, after five directors resigned effective October 23.
GeoVax Labs, Inc. disclosed in an 8-K that effective November 8, 2026, the Board of Directors appointed Tyler O'Brien as interim Chief Executive Officer.1 Until a permanent principal executive officer is appointed or designated, O'Brien will perform the functions of principal executive officer, including for purposes of the certifications required by Rules 13a-14 and 15d-14 under the Exchange Act and Sections 302 and 906 of the Sarbanes-Oxley Act of 2002.1 Effective the same date, O'Brien was also appointed as Chairman of the Board.1
The leadership change follows two earlier moves. Effective November 5, 2026, the Board of Directors appointed Shahin Behroyan as a director of the Company.1 Behroyan was appointed to fill a vacancy on the Board of Directors resulting from the resignation of five former directors, effective October 23, 2026.1 The board determined that Behroyan is independent under Nasdaq Listing Rule 5605(a)(2) and satisfies the independence requirements of Rule 10A-3 under the Exchange Act.1 Behroyan, age 39, is described as a Vancouver-based entrepreneur and business leader with more than two decades of experience spanning investments, consumer packaged goods, healthcare and wellness, politics, and market research.1 He has served as chief executive officer of iSpecimen, Inc. (Nasdaq: ISPC) since August 26, 2026.1
Separately, in a related filing, GeoVax disclosed that on November 5, 2026, David A. Dodd was terminated as President and Chief Executive Officer of the Company, effective immediately.2 Dodd remains a director of the Company and the Chairman of the Board of Directors2 as of that filing, a role O'Brien has since assumed as of November 8. The Board of Directors determined to treat the termination as a termination for "Cause" as defined in Dodd's Employment Agreement, based on his refusal to comply with Board-approved directives.2 The company stated that Dodd's termination is unrelated to the Company's business operations, financial results, or previously filed financial statements.2
