Stockholders' Equity Note [Abstract] |
STOCKHOLDERS' EQUITY | 8. STOCKHOLDERS’ EQUITY Registered Offering On March 21, 2024, we completed an underwritten public offering of 41,999,998 shares of our common stock and a pre-funded warrant to purchase 8,002,668 shares of our common stock, or the 2024 pre-funded warrant. All of the securities were issued separately. The public offering price of the common stock was $3.00 per share. The public offering price of the 2024 pre-funded warrant was $2.99 per share. The 2024 pre-funded warrant has an exercise price of $0.001 per share and may be exercised at any time until the 2024 pre-funded warrant is exercised in full. As of June 30, 2024, none of the 2024 pre-funded warrant has been exercised. The net cash proceeds from the March 2024 offering were approximately $141.0 million, after deducting the underwriting discount and other offering expenses paid by us, and excluding any future proceeds from the exercise of the pre-funded warrant. Upon the issuance of the 2024 pre-funded warrant, we evaluated the warrant terms to determine the appropriate accounting and classification pursuant to FASB Accounting Standards Codification Topic 480, Distinguishing Liabilities from Equity, and FASB Accounting Standards Codification Topic 815, Derivatives and Hedging. Warrants are classified as liabilities when the warrant terms allow settlement of the warrant exercise in cash and classified as equity when the warrant terms only allow settlement in shares of common stock. The terms of the 2024 pre-funded warrant include certain provisions related to fundamental transactions and a cashless exercise provision in the event registered shares are not available, and do not include any mandatory redemption provisions. Based on our evaluation, we concluded the 2024 pre-funded warrant should be classified as equity with no subsequent remeasurement as long as such warrant continue to be classified as equity. Warrant Exercises In the first quarter of 2024, warrants to purchase 37,640 shares of our common stock were exercised for net cash proceeds of approximately $49,000. In the second quarter of 2024, warrants to purchase 281,211 shares of our common stock were exercised for net cash proceeds of approximately $365,000. The warrants were issued in connection with underwritten public offerings of common stock and pre-funded warrants, together with accompanying stock purchase warrants in May 2020. As of June 30, 2024, the following warrants remained outstanding: • pre-funded warrants with an exercise price of $0.001 per share to purchase 59,433,145 shares of our common stock, which have no expiration date; and • stock purchase warrants with an exercise price of $1.30 per share to purchase 2,155,650 shares of our common stock related to the public offering of our common stock in May 2020, which expire on December 31, 2025.
