Stockholders' Equity Note [Abstract] |
Stockholders' Equity | 7. STOCKHOLDERS' EQUITY The Company’s authorized capital stock consists of 500,000,000 shares, all with a par value of $0.0001 per share, of which 490,000,000 shares are designated as common stock and 10,000,000 shares are designated as preferred stock. ATM Facility In November 2022, the Company filed a shelf registration statement on Form S-3 (File No. 333-268288) (the “Shelf Registration Statement”) with the SEC, which permits the offering, issuance and sale by the Company of up to a maximum aggregate offering price of $200.0 million of its common stock and preferred stock, various series of debt securities and/or warrants to purchase any of such securities, of which $50.0 million of common stock may be issued and sold pursuant to an ATM. The Company entered into a Controlled Equity Offering SM sales agreement (the "Sales Agreement") with Cantor Fitzgerald & Co. (“Cantor Fitzgerald”) and Truist Securities, Inc. (“Truist”) under which Cantor Fitzgerald and Truist agreed to act as sales agents to sell shares of the Company’s common stock, from time to time, through the ATM program. On March 8, 2024, the Company delivered a termination notice to Truist, removing them as a sales agent under the ATM program. Such termination became effective on March 14, 2024. Under current SEC regulations, if at any time the Company's public float is less than $75.0 million, and for so long as the Company's public float remains less than $75.0 million, the amount the Company can raise through primary public offerings of securities in any 12-month period using shelf registration statements is limited to an aggregate of one-third of the Company's public float, which is referred to as the baby shelf rules. As of December 31, 2023, the Company's calculated public float was less than $75.0 million. During the year ended December 31, 2023, the Company sold an aggregate of 7,492,580 shares of its common stock under the ATM program, resulting in net proceeds of approximately $14.4 million after deducting underwriting discounts. Through May 2, 2024, the Company sold an aggregate of 856,624 shares of its common stock under the ATM program, resulting in net proceeds of approximately $1.0 million after deducting underwriting discounts.
