Subsequent Events [Abstract]
Subsequent Event	Subsequent Events The Company evaluated subsequent events and transactions that occurred after the balance sheet date up to the date that the unaudited Condensed Consolidated Financial Statements were issued. Other than as described below, the Company did not identify any subsequent events that would have required adjustment or disclosure in the unaudited Condensed Consolidated Financial Statements. Tranche B SPA Funding In April 2023, Senyun, a Purchaser affiliated with ATW Partners LLC and RAAJJ Trading LLC purchased additional senior secured notes and SPA Warrants of the Company. The Company received gross proceeds of $4.0 million ($3.6 million net of original issuance discount) in exchange for such issuances. Tranche C SPA Funding In April and May 2023, Senyun and a Purchaser affiliated with ATW Partners LLC purchased additional senior secured notes and SPA Warrants of the Company. The Company received gross proceeds of $15.0 million ($13.5 million net of original issuance discount) in exchange for such issuances. Equity Awards On April 17, 2023, the Board granted, under the 2021 SI Plan, a total of 54,011 fully vested RSUs, with a grant date value of $0.35, to non-employee directors of the Company. On April 27, 2023, the Board granted, under the 2021 SI Plan, a total of 386,574 RSUs, with a grant date value of $0.27, to certain employees of the Company. Amendment No. 8 to the SPA On May 8, 2023, and May 9, 2023, the Company amended the terms of the SPA with Senyun, FF Simplicity and FF Prosperity (together, “ATW Parties”) (“Amendment No. 8”), pursuant to which: (i) the definition of Floor Price (as defined in each such Secured SPA Note), was amended from $0.21 to $0.10; (ii) Make-whole Interest shall be paid upon conversion of principal of the Secured SPA Notes; (iii) the conversion price for the Secured SPA Notes was amended from $1.05 to $0.89, subject to adjustment as set forth in the Secured SPA Notes; and (iv) the exercise price for the Secured SPA Warrants was amended from $1.05 to $0.89, subject to adjustment as set forth in the Secured SPA Warrants. Unsecured Securities Purchase Agreement On May 8, 2023, the Company entered into the Unsecured SPA with Unsecured SPA Purchasers to issue and sell, subject to the satisfaction of certain closing conditions, $100.0 million aggregate principal amount of the Company’s senior unsecured convertible promissory notes. The Unsecured SPA Purchasers committed to fund in eight subsequent closings fifteen days apart, subject to the satisfaction of certain closing conditions. In addition, any Unsecured SPA Purchaser may postpone or cancel any closing pursuant to the Unsecured SPA in its reasonable discretion if it reasonably determines, based on public information, that the first phase of the Company’s three-phase delivery plan as disclosed in public filings has not begun or will not begin prior to May 31, 2023 and/or the second phase of such delivery plan has not begun or will not begin prior to June 30, 2023, in each case within 15 calendar days of such deadline. The Unsecured SPA Notes are subject to an original issue discount of 10%, accrue interest at 10% per annum, and are convertible into shares of Class A Common Stock of the Company, at a conversion price equal to $0.89, plus an interest make-whole amount, subject to certain adjustments including full ratchet anti-dilution price protection. Each Unsecured SPA Note matures on the date that is six years. Under the Unsecured SPA Notes, at each closing, the Unsecured SPA Purchaser is entitled to receive an Unsecured SPA Warrant registered in the name of such Unsecured SPA Purchaser to purchase up to a number of shares of Common Stock equal to 33% of such shares issuable to such Unsecured SPA Purchaser upon conversion of the aggregate principal amount under the Unsecured SPA Note funded at such closing, with an exercise price equal to $0.89 per share, subject to full ratchet anti-dilution price protection and other adjustments, and are exercisable for seven years on a cash or cashless basis. Each Unsecured SPA Purchaser has the option, from time to time for 12 months after the date of the Unsecured SPA, to purchase additional convertible senior unsecured notes and warrants on the same terms as the Unsecured SPA Notes in an aggregate amount not to exceed 50% of the initial principal amount of the Unsecured SPA Notes issued to such Unsecured SPA Purchaser, subject to certain conditions. On May 10, 2023, the Company received gross proceeds pursuant to the Unsecured SPA totaling $3.3 million ($3.0 million net of original issuance cost). Note Conversions Between April 1, 2023 and May 12, 2023 the Purchasers converted portions of an aggregate principal amount of $60.2 million of the SPA Notes at a conversion price of $1.05 to $0.14 per share into 299,648,761 shares of Class A Common Stock. Between April 1, 2023 and May 12, 2023 the Purchasers converted portions of an aggregate principal amount of $3.3 million of the Unsecured Notes at a conversion price of $0.89 to $0.14 per share into 23,691,100 shares of Class A Common Stock. Authorized Shares As of the date of the issuance of the unaudited Condensed Consolidated Financial Statements, the Company may not have sufficient remaining authorized shares of Class A Common Stock to fulfill its obligation to issue shares upon exercise of all of the warrants and conversion of all of the notes issued or issuable under the SPA, or to pay interest Make-Whole Amounts in shares upon conversion of such notes. Under the SPA, each Purchaser has the option, from time to time until November 10, 2023, to purchase additional Tranche B Notes and warrants of the Company, subject to certain conditions, in an aggregate amount not to exceed the initial principal amount of the Bridge Notes and Incremental Notes issued to such Purchaser. Under the NPA, the Investors have a similar option to acquire additional Optional Notes and warrants of the Company, subject to certain conditions. If there is an insufficient number of remaining authorized shares of Class A Common Stock, the Company would be required to pay the interest “Make-Whole Amount” in cash, which could adversely affect the Company’s liquidity position, business and results of operations. In order to have a sufficient number of authorized shares of common stock to issue to the Purchasers and/or Investors pursuant to the NPA and SPA, the Company may call a subsequent special meeting to obtain stockholder approval to further increase the Company’s authorized shares of common stock.
