Public Stock Offerings

In November 2023, the Company entered into a new Equity Distribution Agreement (the “2023 Equity Agreement”) with Piper Sandler & Co, (“Piper”) in connection with the establishment of an at-the-market offering program under which the Company may sell shares of its common stock, from time to time through Piper as sales agent, in an initial amount of up to $50 million. The 2023 Equity Agreement supersedes and replaces the Company’s previous Equity Distribution Agreement with Piper dated December 18, 2020 (the “2020 Equity Agreement”), which is no longer effective. No sales were made under the 2023 Equity Agreement or the 2020 Equity Agreement during the years ended December 31, 2023, 2022 or 2021.

On October 24, 2024, the Company completed an underwritten public offering of 14,670,000 shares of its common stock, including the exercise in full of the underwriters’ overallotment option to purchase additional shares of common stock, at a price to the public of $2.25 per share and, in lieu of common stock to investors who so chose, pre-funded warrants to purchase 5,800,000 shares of common stock at a public offering price of $2.2499 per pre-funded warrant, which represents the per share public offering price for the shares of common stock less the $0.0001 per share exercise price for each pre-funded warrant. The offering resulted in net proceeds of $42.9 million, after deducting underwriting discounts and commissions and other estimated offering expenses and assuming no subsequent exercise of the pre-funded warrants. The exercise of the pre-funded warrants, if any, is not expected to provide significant additional funding to the Company.

In April 2023, the Company completed an underwritten public offering in which the Company issued and sold 5,219,190 shares of its common stock (including 469,190 shares sold pursuant to the underwriters’ overallotment option in May 2023) at a public offering price of $9.50 per share. The Company received net proceeds of approximately $46.3 million after deducting underwriting discounts, commissions and other offering expenses.

In August 2022, the Company completed an underwritten public offering in which the Company issued and sold 4,600,000 shares of its common stock at a public offering price of $8.00 per share. The Company received net proceeds of $34.4 million after deducting underwriting discounts, commissions and other offering expenses.

There have been no exercises or cancellations of warrants during the year ended December 31, 2024. The Company had the following warrants outstanding at December 31, 2024:

			Exercise	Expiration

On October 24, 2024, in connection with the underwritten public offering, the Company granted pre-funded warrants to purchase 5,800,000 shares of common stock at a public offering price of $2.2499 per pre-funded warrant, which represents the per share public offering price for the shares of common stock less the $0.0001 per share exercise price for each pre-funded warrant. The common stock and pre-funded warrants each met the criteria for equity classification. Accordingly, the amount allocated to the pre-funded warrants was recorded as a component of stockholders’ equity within additional paid-in capital.
