Amendment Description	Sandbridge Acquisition Corporation (the “Company,” “we,” “our” or “us”) is filing this Annual Report on Form 10-K/A (Amendment No. 1) (this “Annual Report”), to amend our Annual Report on Form 10-K for the year ended December 31, 2020, originally filed with the Securities and Exchange Commission (the “SEC”) on March 25, 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 on March 17, 2020, our outstanding warrants to purchase common stock (the “Warrants”) were accounted for as equity within our balance sheet. After discussion and evaluation, with our Audit Committee of our Board of Directors, and taking into consideration the SEC Staff Statement, we have concluded that the Warrants should be presented as liabilities with subsequent fair value remeasurement. Therefore, the Audit Committee, in consultation with its management, concluded that the Company’s (i) previously issued audited balance sheet dated as of September 17, 2020 which was related to its initial public offering, (ii) unaudited interim financial statements as of and for the quarterly period ended September 30, 2020, as reported in the Company’s Quarterly Report on Form 10-Q filed with the SEC on November 13, 2020, and (iii) audited financial statements as of December 31, 2020 and for the period from June 23, 2020 (inception) through December 31, 2020 as reported in the Company’s Annual Report on Form 10-K filed with the SEC on March 25, 2021 (collectively, the “Affected Periods”) should be restated because of a misapplication in the guidance around accounting for the Warrants and should no longer be relied upon.
