| Amendment Description | This Amendment No. 1 on Form 10-K/A (this “Amendment”) amends the Annual Report on Form 10-K of NovaBay Pharmaceuticals, Inc. for the fiscal year ended December 31, 2023, as filed with the Securities and Exchange Commission on March 26, 2024 (the “Original Filing”). Exhibit 4.1 (Description of Securities) (the “Description of Securities”) was inadvertently omitted in the Original Filing. This Amendment is being filed solely to file the Description of Securities. No other changes were made to the Original Filing. Further, no attempt has been made in this Amendment to modify or update the other disclosures presented in the Original Filing. This Amendment does not reflect events occurring after the filing of the Form 10-K (i.e., occurring after March 26, 2024) or modify or update those disclosures that may be affected by subsequent events. Accordingly, this Amendment should be read in conjunction with the Original Filing and the registrant’s other filings with the Securities and Exchange Commission. In accordance with Rule 12b-15 of the Securities Exchange Act of 1934, as amended, this Amendment includes new certifications required by Sections 302 and 906 of the Sarbanes-Oxley Act of 2002, as amended, dated as of the filing date of this Amendment. | ||
