Amendment Description The Company is filing this amendment No. 1 on Form 10-K/A (“Form 10-K/A”) to amend our Annual Report on Form 10-K for the year ended December 31, 2021, originally filed with the Securities and Exchange Commission (the SEC”) on March 31, 2022 (the “Original Report”), to restate our consolidated financial statements and related footnote disclosures as of December 31, 2021 and for the year then ended. This Form 10-K/A also amends certain other Items in the Original Report, as listed in “Items Amended in this Form 10-K/A” below.Restatement BackgroundOn May 16, 2022, the audit committee of the board of directors (the “Audit Committee”) of the Company, based on the recommendation of, and after consultation with, the Company’s management concluded that the Company’s previously issued audited financial statements as of and for the year ended December 31, 2021, should no longer be relied upon. As part of the Company’s accounting for revenue contracts with customers during the first quarter of 2022, management considered ongoing contracts that were entered into and accounted for during the year ended December 31, 2021. During this evaluation, it was determined that a government contract which had previously been assessed as within the scope of ASC 606, Revenue from Contract with Customers (“ASC 606”), should have been accounted for as a government grant and therefore not within the scope of ASC 606. The impact of this revised conclusion resulted in (i) the separate presentation of amounts previously presented as revenue and cost of revenue as grant revenue and cost of grant revenue, respectively, (ii) no change to total revenue, and (iii) a reduction in total cost of revenue, including the reversal of a contract loss recognized during the year ended December 31, 2021. The change in our accounting of the government contract resulted in changes to our consolidated balance sheet as of December 31, 2021, our consolidated statements of operations and comprehensive loss, consolidated statement of convertible preferred stock and shareholder’s equity (deficit), and consolidated statement of cash flows, each for the year ended December 31, 2021, and the Company’s loss per share. Additionally, management recorded an immaterial correction resulting in an increase to cost of revenue and a decrease to selling, general and administrative expense that was separate from the change in accounting of the government contract. No adjustments were identified as of and for the year ended December 31, 2020.Items Amended in this Form 10-K/AThis Form 10-K/A presents the Original Report, amended and restated with modifications as necessary to reflect the restatements.
