Equity [Abstract]
Warrant Liabilities	Warrant Liabilities December 2022 Warrants On December 12, 2022, in connection with the sale of 9,090,909 shares of our common stock to an institutional investor, we entered into a warrant agreement that allows such investor to purchase up to 9,090,909 shares at an exercise price of $6.60 per share. We classified the warrants as a liability at their fair value determined using the Black-Scholes option pricing model. The fair value of the warrants was estimated at $35.1 million at the issuance date. Of the placement agent fees and other offering costs totaling $3.0 million, $1.1 million was allocated to the warrants and recorded in other expense, net, on the consolidated statement of operations on the date of the transaction. As of December 31, 2023 and 2022, all 9,090,909 underlying warrants were outstanding. As of December 31, 2023 and 2022, the estimated fair value of the warrants were $17.1 million and $21.6 million, respectively. During the year ended December 31, 2023, a decrease in fair value of $4.5 million was recorded in other expense, net, on the consolidated statement of operations. February 2023 Warrants On February 15, 2023, in connection with the sale of 14,072,615 shares of our common stock to certain institutional investors, we entered into a warrant agreement that allows such investors to purchase up to 14,072,615 shares at an exercise price of $4.2636 per share. We classified the warrants as a liability at their fair value determined using the Black-Scholes option pricing model. The fair value of warrants was estimated at $23.7 million at the issuance date. Of the placement agent fees and other offering costs totaling $3.0 million, $1.0 million was allocated to the warrants and recorded in other expense, net, on the consolidated statement of operations on the date of the transaction. On July 25, 2023, the company amended the terms of the warrant, reducing the exercise price of the warrants from $4.2636 per share to $3.2946 per share and extending the expiration date of the warrants until July 24, 2026. Since the warrants were classified as liabilities and measured at fair value, we recognized the change of $7.3 million in fair value of warrant liability in earnings due to the warrant modification. As of December 31, 2023, all 14,072,615 underlying warrants were outstanding, with an estimated fair value of $50.0 million.
