Amendment Description	This Amendment No. 1 on Form 10-K/A (this Form 10-K/A), to the Annual Report on Form 10-K of Genelux Corporation, (Genelux, the Company, we, us, our and similar references), for the fiscal year ended December 31, 2024, filed with the Securities and Exchange Commission (the SEC), on March 28, 2025 (the Original Form 10-K), is being filed solely for the purpose of including the information required by Part III to the Annual Report on Form 10-K. This information was previously omitted from the Original Form 10-K in reliance on General Instruction G(3) to Form 10-K, which permits the information in the above referenced items to be incorporated in the Form 10-K by reference from our definitive proxy statement if such statement is filed no later than 120 days after our fiscal year-end. We are filing this Form 10-K/A to include Part III information because we will not file a definitive proxy statement containing such information within 120 days after the end of the fiscal year covered by the Original Form 10-K. In addition, this Form 10-K/A deletes the reference on the cover of the Original Form 10-K to the incorporation by reference of portions of our proxy statement into Part III of the Original Form 10-K. Pursuant to Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the Exchange Act), this Form 10-K/A also contains certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002, which are attached hereto. Because no financial statements have been included in this Form 10-K/A and this Form 10-K/A does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4, and 5 of the certifications have been omitted, as required by Question 161.01 of the Compliance and Disclosure Interpretations of the Division of Corporation Finance of the SEC. Except as described above, this Form 10-K/A does not modify or update disclosure in, or exhibits to, the Original Form 10-K. Furthermore, this Form 10-K/A does not change any previously reported financial results. Information not affected by this Form 10-K/A remains unchanged and reflects the disclosures made at the time the Original Form 10-K was filed.
