| Amendment Description | EXPLANATORY NOTE This Amendment No. 1 (this “Amendment”) on Form 10-K/A amends Telesis Bio Inc.’s (the “Company,” “Telesis,” “we,” “us” or “our”) Annual Report on Form 10-K for the year ended December 31, 2022 filed with the Securities and Exchange Commission (the “SEC”) on March 22, 2023 (the “Original 10-K”), to include the information required by Items 10 through 14 of Part III of the Original 10-K. This information was previously omitted from the Original 10-K 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 to our definitive proxy statement if such statement is filed no later than 120 days after our fiscal year-end. We are filing this Amendment to include Part III information in our Form 10-K because a definitive proxy statement containing such information may not be filed by the Company within 120 days after the end of the fiscal year covered by the Form 10-K. Pursuant to the SEC rules, Part IV, Item 15 has also been amended to contain the currently dated certificates from the Company’s principal executive and financial officer and principal accounting officer pursuant to Section 302 of the Sarbanes-Oxley Act of 2002. The certificates of the Company’s principal executive and financial officer and principal accounting officer are attached to this Amendment as Exhibit 31.2. 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. Additionally, 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 for the changes to Part III and the filing of related certifications added to the list of Exhibits in Part IV, this Amendment makes no changes to the Original 10-K. Unless otherwise stated, this Amendment does not reflect events occurring after the filing of the Original 10-K or modify disclosures affected by subsequent events. Terms used but not otherwise defined in the Amendment have such meaning as ascribed to them in the Original 10-K. | | |
