STOCKHOLDERS' EQUITY	6. STOCKHOLDERS’ EQUITY Public Offering On January 10, 2023 we completed the January 2023 offering consisting of 68,007,741 shares of our common stock and the 2023 pre-funded warrant. All of the securities were issued separately. The public offering price of the common stock was $2.45 per share. The public offering price of the 2023 pre-funded warrant was $2.449 per share. The 2023 pre-funded warrant has an exercise price of $0.001 per share and may be exercised at any time until the 2023 pre-funded warrant is exercised in full. As of June 30, 2023, none of the 2023 pre-funded warrant has been exercised. The net cash proceeds from this offering were $213,337,000, after deducting the underwriting discount and other offering expenses paid by us, and exclude any future proceeds from the exercise of the 2023 pre-funded warrant. Upon the issuance of the 2023 pre-funded warrant, we evaluated the terms of each warrant 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 2023 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 2023 pre-funded warrant should be classified as equity with no subsequent remeasurement as long as such warrant continue to be classified as equity.
