Equity [Abstract] |
Capital Stock | Capital Stock Exercise of Options For the nine months ended September 30, 2025 and 2024, we issued 339,142 and 72,856 shares, respectively, upon option exercises at a weighted-average exercise price of $3.09 and $1.97 per share, respectively, with net cash proceeds of $1.0 million and $0.1 million, respectively. Sales Agreements In May 2021, we filed a Registration Statement on Form S-3 with the SEC (the “2021 Registration Statement”), that automatically became effective upon its filing, under which we were permitted to sell common stock, preferred stock, debt securities, warrants, purchase contracts, and units from time to time in one or more offerings. On February 27, 2023, we filed a post-effective amendment to the 2021 Registration Statement. Pursuant to that post-effective amendment, we registered an aggregate $200.0 million of securities. In May 2021, we entered into an Equity Distribution Agreement (“EDA”) with Piper Sandler & Co (“PSC”), under which PSC, as our exclusive agent, at our discretion and at such times that we determined from time to time, may have sold over a three-year period from the execution of the EDA up to a maximum of $50.0 million of shares of our common stock. Under the terms of the EDA, PSC was permitted to sell the shares at market prices by any method that is deemed to be an “at the market offering” as defined in Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”). We were not required to sell any shares at any time during the term of the EDA. On April 24, 2024, we terminated the EDA. No shares of our common stock were issued and sold pursuant to the EDA during the three and nine months ended September 30, 2024. On May 2, 2024, we entered into a Controlled Equity Offering℠ Sales Agreement (the “Cantor Sales Agreement”) with Cantor Fitzgerald & Co., as sales agent (“Cantor”), under which Cantor, at our discretion and at such times that we may determine from time to time, may sell up to a maximum of $75.0 million of shares of our common stock. Under the terms of the Cantor Sales Agreement, Cantor may sell the shares at market prices by any method that is deemed to be an “at the market offering” as defined in Rule 415 under the Securities Act. On May 2, 2024, we filed a registration statement on Form S-3 registering the offer and sale of these shares under the Securities Act which became effective on May 14, 2024. We will pay a commission of up to 3.0% of gross sales proceeds of any common stock sold under the Cantor Sales Agreement. In 2024, 10,440,000 shares of our common stock were issued and sold pursuant to the Cantor Sales Agreement, all during the third quarter of 2024, and we received net proceeds of $29.7 million after Cantors’ commissions and direct offering expenses. During the nine months ended September 30, 2025, 7,244,966 shares of our common stock were issued and sold pursuant to the Cantor Sales Agreement, all during the second quarter of 2025, and we received gross proceeds of $17.3 million, or $16.4 million in net proceeds after the Cantors’ commissions and direct offering expenses of $0.8 million. As of September 30, 2025, $26.4 million remained available for sale under the Cantor Sales Agreement.
