| Amendment Description | Perception Capital Corp. II (the “company”) is filing this Amendment No. 1 on Form 10-K/A (the “Amendment”) to amend the 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 27, 2023 (the “Form 10-K”). The sole purpose of this Amendment is to correct an inadvertent omission of certain language from paragraph 4 of the Section 302 certifications originally filed in the Form 10-K as Exhibit 31.1 and Exhibit 31.2. Because no financial statements have been included in this Amendment, paragraph 3 of the Section 302 certifications filed herewith as Exhibits 31.1 and 31.2 have been omitted. This Amendment contains only the Cover Page, this Explanatory Note and Exhibits 31.1 and 31.2. Other than as expressly set forth in this Amendment, this Amendment does not amend, modify or restate any other information or disclosures presented in the Form 10-K. This Amendment does not reflect events occurring after the original filing of the Form 10-K. Accordingly, the company’s Form 10-K continues to speak as of March 27, 2023 and this Amendment should be read in conjunction with the Form 10-K and other company filings made with the SEC. | |
