| Amendment Description | Accustem Sciences, Inc. (the “Company”) is filing this Amendment No. 1 on Form 10-K/A to amend its Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the Securities and Exchange Commission on February 15, 2023 (the “Original Filing”), to include the information required by Part III of Form 10-K. The Part III information was previously omitted from the Original Filing 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. The information required by Items 10-14 of Part III is no longer being incorporated by reference to the proxy statement relating to our 2023 Annual Meeting of Shareholders. The reference on the cover of the Original Filing to the incorporation by reference to portions of our definitive proxy statement into Part III of the Original Filing is hereby deleted. This Amendment No. 1 is not intended to update any other information presented in the Original Filing. In addition, as required by Rule 12b-15 promulgated under the Securities Exchange Act of 1934, as amended (Exchange Act), new certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002 by our principal executive officer and principal financial officer are filed herewith as exhibits to this Amendment No.1. 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 | ||
