Stockholders' Equity Note [Abstract] |
Stockholders' Equity | 6. Stockholders' Equity ATM Program On May 16, 2023, the Company entered into a sales agreement (the Sales Agreement) with Wedbush Securities, Inc. (Wedbush), as sales agent, pursuant to which the Company could offer, issue and sell up to an aggregate amount of $75.0 million of shares of the Company's voting common stock, par value $0.0001 per share (Voting Common Stock), from time to time in “at-the-market” (ATM) offerings during the term of the Sales Agreement under a registration statement on Form S-3 (File No. 333-268260) filed with the SEC, which was declared effective on May 16, 2023. No Voting Common Stock has been sold under this Sales Agreement to date. Equity Offerings On June 1, 2023, the Company completed an underwritten public offering resulting in the issuance and sale of (a) 23,287,134 shares of Voting Common Stock, at a price of $2.00 per share, and (b) pre-funded warrants (Pre-Funded Warrants) to purchase up to 47,010,526 shares of the Voting Common Stock, at a price of $1.9999 per warrant with an exercise price of $0.0001 per share. The Company received aggregate net proceeds of $134.7 million after deducting underwriting discounts, commissions and other offering expenses, with $42.4 million allocated to the Voting Common Stock and $92.3 million allocated to Pre-Funded Warrants. On April 24, 2024, the Company completed an underwritten public offering resulting in the issuance and sale of (a) 4,958,068 shares of Voting Common Stock, including the partial exercise of the underwriters’ option to purchase 2,485,487 additional shares of Voting Common Stock, at the closing market price on April 16, 2024, of $7.13 per share, and (b) Pre-Funded Warrants to purchase up to 18,577,419 shares of the Voting Common Stock, at a price of $7.1299 per warrant with an exercise price of $0.0001 per share. The Company received aggregate net proceeds of approximately $161.4 million after deducting underwriting discounts, commissions and other offering expenses, with $33.1 million allocated to the Voting Common Stock and $128.3 million allocated to Pre-Funded Warrants. On December 27, 2024, the Company completed a registered direct offering with an existing investor for the issuance of pre-funded warrants to purchase up to 7,500,000 shares of the Company's Voting Common Stock, with an exercise price of $0.0001 per warrant. The pre-funded warrants were issued at a purchase price of $4.00 per warrant, resulting in gross proceeds of approximately $30.0 million, before deducting offering expenses of $0.2 million. The Pre-Funded Warrants are immediately exercisable subject to certain ownership limitations, have an exercise price of $0.0001 per share, may be exercised at any time and do not expire. The Pre-Funded Warrants were determined to be equity classified because they are freestanding financial instruments that are legally detachable and separately exercisable from the equity instruments, are immediately exercisable, do not embody an obligation for the Company to repurchase its shares, permit the holders to receive a fixed number of common shares upon exercise, are indexed to the Company’s common stock and meet the equity classification criteria. In addition, the Pre-Funded Warrants do not provide any guarantee of value or return. As such, proceeds received from the issuance from the Pre-Funded Warrants were recorded as a component of stockholders’ equity within additional paid-in capital. As of December 31, 2024, no Pre-Funded Warrants have been exercised.
