Amendment Description	This Amendment No. 1 on Form 10-K/A (this “Amendment”) amends the Annual Report on Form 10-K of GeoVax Labs, Inc. for the fiscal year ended December 31, 2021, originally filed with the Securities and Exchange Commission on March 9, 2022 (the “Original Filing”). We are filing this Amendment to amend Part III of the Original Filing to include the information required by and not included in Part III of the Original Filing because we will not file our definitive proxy statement within 120 days of the end of our fiscal year ended December 31, 2021. In connection with the filing of this Amendment and pursuant to the rules of the Securities and Exchange Commission, we are including with this Amendment new certifications by our principal executive and principal financial officers; accordingly, Item 15 of Part IV has also been amended to reflect the filing of these new certifications.   Except as described above, no other changes have been made to the Original Filing. The Original Filing continues to speak as of the date of the Original Filing, and we have not updated the disclosures contained therein to reflect any events which occurred at a date subsequent to the filing of the Original Filing other than as expressly indicated in this Amendment. In this Amendment, unless the context indicates otherwise, the terms “Company,” “we,” “us,” and “our” refer to GeoVax Labs, Inc. and its subsidiaries. Other defined terms used in this Amendment but not defined herein shall have the meaning specified for such terms in the Original Filing.   All statements in this Amendment that are not historical are forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements can generally be identified as such because the context of the statement will include words such as “may,” “will,” “intend,” “plans,” “believes,” “anticipates,” “expects,” “estimates,” “predicts,” “potential,” “continue,” “opportunity,” “goals,” or “should,” the negative of these words or words of similar import. Similarly, statements that describe our future plans, strategies, intentions, expectations, objectives, goals or prospects are also forward-looking statements. These forward-looking statements are or will be, as applicable, based largely on our expectations and projections about future events and future trends affecting our business, and so are or will be, as applicable, subject to risks and uncertainties including but not limited to the risk factors discussed in the Original Filing, that could cause actual results to differ materially from those anticipated in the forward-looking statements. We caution investors that there can be no assurance that actual results or business conditions will not differ materially from those projected or suggested in such forward-looking statements. Our views and the events, conditions and circumstances on which these future forward-looking statements are based, may change.
