Amendment Description References throughout this Amendment No. 1 to the Annual Report on Form 10-K to “we,” “us,” the “Company” or “our company” are to Prime Impact Acquisition I, unless the context otherwise indicates. This Amendment No. 1 (“Amendment No. 1”) to the Annual Report on Form 10-K/A amends the Annual Report on Form 10-K of Prime Impact Acquisition I for the fiscal year ended December 31, 2020, as filed with the Securities and Exchange Commission (“SEC”) on March 31, 2021 (the “Original Filing”).On April 12, 2021, the staff of the Securities and Exchange Commission (the “SEC Staff”) issued a public statement entitled “Staff Statement on Accounting and Reporting Considerations for Warrants issued by Special Purpose Acquisition Companies (“SPACs”)” (the “SEC Staff Statement”). In the SEC Staff Statement, the SEC Staff expressed its view that certain terms and conditions common to SPAC warrants may require the warrants to be classified as liabilities on the SPAC’s balance sheet as opposed to equity. Since issuance in September 2020, our warrants were accounted for as equity within our balance sheet. After discussion and evaluation, including with our registered public accounting firm and our audit committee, and taking into consideration the SEC Staff Statement, we have concluded that our warrants should be presented as liabilities with subsequent fair value remeasurement. As a result of the foregoing, on May 20, 2021, the Audit Committee of the Company, in consultation with its management, concluded that its previously issued Financial Statements for the periods beginning with the period from July 21, 2020 (inception) through December 31, 2020, the balance sheet dated September 14, 2020, and the unaudited interim financial statements as of, and for the periods ended, September 30, 2020 (collectively, the “Affected Periods”) should be restated because of a misapplication in the guidance around accounting for our outstanding warrants to purchase Class A ordinary shares (the “Warrants”) and should no longer be relied upon. Historically, the Warrants were reflected as a component of equity as opposed to liabilities on the balance sheets and the statements of operations did not include the subsequent non-cash changes in estimated fair value of the Warrants, based on our application of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 815-40, Derivatives and Hedging, Contracts in Entity’s Own Equity (“ASC 815-40). The views expressed in the SEC Staff Statement were not consistent with the Company’s historical interpretation of the specific provisions within its warrant agreement and the Company’s application of ASC 815-40 to the warrant agreement. We reassessed our accounting for the Warrants issued in September 2020, in light of the SEC Staff’s published views. Based on this reassessment, we determined that the Warrants should be classified as liabilities measured at fair value upon issuance, with subsequent changes in fair value reported in our Statement of Operations each reporting period. The change in accounting for the Warrants did not have any impact on our liquidity, cash flows, revenues or costs of operating our business and the other non-cash adjustments to the Financial Statements, in all of the Affected Periods or in any of the periods included in Item 8, Financial Statements and Supplementary Data in this filing. The change in accounting for the warrants does not impact the amounts previously reported for the Company’s cash and cash equivalents, investments held in the trust account, operating expenses or total cash flows from operations for any of these periods. We are filing this Amendment No. 1 to amend and restate the Original Filing with modification as necessary to reflect the restatements. The following items have been amended to reflect the restatements: Part I, Item 1A. Risk Factors Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations Part II, Item 8. Financial Statements and Supplementary Data Part II, Item 9A. Controls and Procedures In addition, the Company’s Chief Executive Officer and Chief Financial Officer have provided new certifications dated as of the date of this filing in connection with this Form 10-K/A (Exhibits 31.1, 31.2, 32.1 and 32.2). Except as described above, no other information included in the Original Filing is being amended or updated by this Amendment No. 1 and this Amendment No. 1 does not purport to reflect any information or events subsequent to the Original Filing. This Amendment No. 1 continues to describe the conditions as of the date of the Original Filing and, except as expressly contained herein, we have not updated, modified or supplemented the disclosures contained in the Original Filing. Accordingly, this Amendment No. 1 should be read in conjunction with the Original Filing and with our filings with the SEC subsequent to the Original Filing.
