| Amendment Description | This Amendment No. 1 on Form 10-K/A, or the Amendment, amends the Annual Report on Form 10-K of Anika Therapeutics, Inc., a Delaware corporation, or we, our, us, Anika, or the Company, for the fiscal year ended December 31, 2023, originally filed with the Securities and Exchange Commission, or the SEC, on March 15, 2024, or the Original Filing. This Amendment is being filed 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 no financial statements have been included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 4 and 5 of the certifications have been omitted. The Company is not including certifications pursuant to Section 1350 of Chapter 63 of Title 18 of the United States Code (18 U.S.C. 1350) as no financial statements are being filed with this Amendment. Except for the matters 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 the Company has 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. Accordingly, this Amendment should be read in conjunction with the Original Filing and the Company’s other filings made with the SEC on or subsequent to March 15, 2024. | ||
