| Amendment Description | Organovo Holdings, Inc. (“Organovo,” the “Company,” “we,” “our” or “us”) is filing this Amendment No. 1 on Form 10-K/A (this “Amendment”) to its Annual Report on Form 10-K for the fiscal year ended March 31, 2021 (“Fiscal 2021”), as filed with the Securities and Exchange Commission (the “SEC”) on June 15, 2021 (the “Original Form 10-K”). The purpose of this Amendment is solely to disclose the information required in Part III (Items 10, 11, 12, 13 and 14) of the Original Form 10-K, which information was previously omitted from the Original Form 10-K in reliance on General Instruction G(3) to Form 10-K. Accordingly, we hereby amend and replace in its entirety Part III of the Original Form 10-K. In addition, pursuant to the rules of the SEC, Item 15 of Part IV has been amended to include the currently dated certifications of the Company’s principal executive officer and principal financial officer required under Section 302 of the Sarbanes-Oxley Act of 2002. 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 3, 4 and 5 of the certifications have been omitted. We are not including the certificate under Section 906 of the Sarbanes-Oxley Act of 2002 as no financial statements are being filed with this Amendment. Except as described above or as otherwise expressly provided by the terms of this Amendment, no other changes have been made to the Original Form 10-K. Except as otherwise indicated herein, this Amendment continues to speak as of the date of the Original Form 10-K, and we have not updated the disclosure contained therein to reflect any events that occurred subsequent to the date of the Original Form 10-K. This Amendment should be read in conjunction with the Original Form 10-K and with our filings with the SEC subsequent to the date on which the Original Form 10-K was filed. |
