Equity [Abstract] |
STOCKHOLDERS' EQUITY | STOCKHOLDERS’ EQUITY At-the-Market Offering Agreement In August 2020, the Company entered into an Open Market Sale Agreement℠ with Jefferies LLC (“Jefferies”) with respect to an at-the-market offering program under which the Company may offer and sell, from time to time at its sole discretion, shares of the Company’s common stock having an aggregate offering price of up to $150.0 million through Jefferies as the Company’s sales agent or principal. In December 2022, the Company entered into Amendment No. 2 to the Open Market Sale Agreement℠ which increased the aggregate offering price under the at-the-market offering program by an additional $175.0 million. Approximately $194.5 million remained available under the sales agreement as of March 31, 2024. The Company is not obligated to sell any shares under the sales agreement. No shares were sold under the sales agreement during the three months ended March 31, 2024. During the three months ended March 31, 2023, the Company sold 3,962,430 shares of its common stock for net proceeds of approximately $9.7 million. Issuance and Sale of Common Stock and Warrants On March 21, 2024, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with certain institutional investors (collectively, the “Investors”). On March 26, 2024 the Company issued and sold in a registered direct offering (the “Registered Direct Offering”) an aggregate of 24,761,905 shares of common stock of the Company, par value $0.01 per share, and pre-funded warrants to purchase up to an aggregate of 3,809,523 shares of common stock, together with accompanying warrants (“Common Warrants”) to purchase up to an aggregate of 28,571,428 shares of common stock. The combined offering price of a unit consisting of one share of common stock and the accompanying Common Warrant to purchase one share of common stock was $0.84. The combined offering price of a unit consisting of a pre-funded warrant to purchase one share of common stock and the accompanying Common Warrant to purchase one share of common stock was $0.83. The pre-funded warrants are immediately exercisable at any time, until exercised in full, at a price of $0.01 per share of common stock. The Common Warrants are exercisable six months from issuance, expire five and a half years from the issuance date and have an exercise price of $1.00 per share. Both pre-funded warrants and Common Warrants can be exercised net in limited circumstances and entitle holders to dividends if and when paid by the Company. Barclays Capital Inc. and Cantor Fitzgerald & Co. (the “Placement Agents”) acted as the placement agents for the offering, pursuant to a Placement Agency Agreement, dated March 21, 2024 (the “Placement Agreement”). Pursuant to the Placement Agreement, the Company paid the Placement Agents a cash placement fee equal to 6.0% of the aggregate gross proceeds raised in the Registered Direct Offering from sales arranged by the Placement Agents. The Company received aggregate net proceeds from the Registered Direct Offering of $21.8 million, net of the Placement Agents’ fees of $1.4 million and other offering costs of $0.7 million. Common Warrants and pre-funded warrants were determined to be equity-classified and proceeds received from their issuance were recorded as a component of stockholders’ equity within additional paid-in capital. The Company determined that the warrants should be equity classified because they are freestanding financial instruments, do not embody an obligation for the Company to repurchase its shares, do not contain exercise contingencies tied to observable markets or indices, permit the holders to receive a fixed number of shares of common stock upon exercise in exchange for a fixed amount of consideration, subject only to adjustments that are inputs to the fair value of a fixed price/fixed consideration-option, and meet the equity classification criteria. The Common Warrants and pre-funded warrants had not been exercised and remained outstanding as of March 31, 2024.
