EXPLANATORY NOTE

This Amendment No. 1 on Form 10-K/A (this "Amendment" amends Avinger, Inc.'s Annual Report on Form 10-K for the year ended December 31, 2022, originally filed with the Securities and Exchange Commission (the "SEC") on March 16, 2023.

This Amendment amends (i) the number of shares outstanding on the cover page to include 1,468,928 unvested restricted stock awards that were granted to certain employees, officers, and directors of the Company in January 2023, (ii) Item 12 of Part III to update the number of shares outstanding as of March 1, 2023 under the heading "Security Ownership of Certain Beneficial Owners and Management" to include 1,468,928 unvested restricted stock awards that were granted to certain employees, officers, and directors of the Company in January 2023 and to include Armistice Capital, LLC as a 5% stockholder, and (iii) Item 15(a)(3) of Part IV to update certain footnote references in the exhibit index.

In addition, as required by Section 302 of the Sarbanes-Oxley Act of 2002 and Rule 12b-15 of the Securities Exchange Act of 1934 (the "Exchange Act"), as amended, updated certifications of the Company's principal executive officer and principal financial officer are included as Exhibits 31.3 and 31.4 hereto. Because no financial statements have been included in this Amendment No. 1 and this Amendment No. 1 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. We are not including the certifications under Section 906 of the Sarbanes-Oxley Act of 2002 as no financial statements are being filed with this Amendment No. 1.

No other changes have been made to the Form 10-K other than those described above. This Amendment No. 1 does not reflect subsequent events occurring after the original filing date of the Form 10-K or modify or update in any way the financial statements, consents or any other items disclosures made in the Form 10-K in any way other than as required to reflect the amendments discussed above. Accordingly, this Amendment No. 1 should be read in conjunction with the Form 10-K and the Company's other filings with the SEC subsequent to the filing of the Form 10-K.

In computing the number of shares of capital stock beneficially owned by a person and the percentage ownership of such person, we deemed to be outstanding all shares of our capital stock subject to options, restricted stock awards ("RSAs") or RSUs held by the person that are currently exercisable, exercisable or vests within 60 days of March 1, 2023. However, we did not deem such shares of our capital stock outstanding for the purpose of computing the percentage ownership of any other person.
