| Stockholders' Equity | 7. Stockholders’ Equity The Company has 45,000,000 shares of common stock authorized, and 15,000,000 authorized shares of preferred stock. As of December 31, 2025, a total of 14,966,449 shares of common stock were outstanding, including 380,730 shares of unvested restricted stock. As of December 31, 2025, warrants to purchase 678,875 shares of common stock of the Company were outstanding. No shares of preferred stock have been issued. The remaining restricted stock outstanding will vest between January 2026 and March 2027. ATM Offering On June 8, 2023, the Company entered into a Controlled Equity OfferingSM Sales Agreement (the “Sales Agreement”) with Cantor Fitzgerald & Co. (the “Agent”), pursuant to which the Company may offer and sell from time to time up to $40,000,000 of shares of the Company’s common stock through the Agent (the “ATM Offering”). The offer and sale of the common stock has been registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to the Company’s registration statement on Form S-3. Sales of the common stock, pursuant to the Sales Agreement, may be made in sales deemed to be an “at the market offering” as defined in Rule 415(a)(4) promulgated under the Securities Act, including sales made directly on or through the New York Stock Exchange or on any other existing trading market for the Company’s common stock. The Company has no obligation to sell any of the common stock under the Sales Agreement and may at any time suspend or terminate the offering of its common stock pursuant to the Sales Agreement upon notice and subject to other conditions. The Agent will act as sales agent and will use commercially reasonable efforts to sell on the Company’s behalf all of the common stock requested to be sold by the Company, consistent with the Agent’s normal trading and sales practices, on mutually agreed terms between the Agent and the Company. The Company pays the Agent a commission of 2.75% of the gross proceeds of the Shares sold through it under the Sales Agreement. The Sales Agreement contains customary representations, warranties and agreements by the Company, customary indemnification obligations of the Company and the Agent against certain liabilities, including for liabilities under the Securities Act, and termination provisions. The Company sold 480,898 shares for the fiscal year ended December 31, 2025 and 87,815 shares for the fiscal year ended December 31, 2024 of common stock pursuant to the Sales Agreement for net proceeds of approximately $9.6 million and $1.8 million, respectively. The balance remaining from the Sales Agreement as of December 31, 2025 is $23.0 million. Underwritten Offering On June 10, 2024, the Company entered into an underwriting agreement (the "June 2024 Underwriting Agreement") with Canaccord Genuity LLC and Cormark Securities Inc. (collectively, the "June 2024 Underwriters"), relating to the underwritten public offering (the “ June 2024 Offering”) of 731,750 units (the "Units") of the Company at a price of $20.50 per Unit. Each Unit consists of (i) one share of the Company's common stock and (ii) one-half of one accompanying warrant. Each whole accompanying warrant is exercisable to purchase one share of the Company's common stock at a price of $26.00 per warrant, exercisable for a period of 36 months. The June 2024 Underwriters agreed to purchase the Units from the Company pursuant to the June 2024 Underwriting Agreement at a price of $19.37 per Unit, which included a 5.5% underwriting discount. The fair value of each warrant was estimated as of the date of grant using the Black-Scholes option-pricing model (Level 2 of the fair value hierarchy) with the following weighted average assumptions used: (i) risk-free interest rate of 4.57%; (ii) expected life of 3.0 years; (iii) expected volatility of 57%; and (iv) expected dividend yield of 0%. The net proceeds from the June 2024 Offering were $13.7 million after deducting underwriting discounts and commissions and offering expenses. The June 2024 Offering was made pursuant to the Company’s effective shelf registration statement on Form S-3. The June 2024 Offering closed on June 12, 2024. As of December 31, 2025, none of the warrants had been exercised. On September 25, 2025, the Company sold 1,975,000 shares of common stock and pre-funded warrants to purchase up to 525,000 shares of common stock at an offering price of $20.00 per share and $19.99 per pre-funded warrant and received gross proceeds of approximately $50.0 million before deducting underwriting discounts and offering expenses of approximately $3.0 million. The offering price of the pre-funded warrant equaled the public offering price per share of the common stock less the $0.01 per share exercise price of each pre-funded warrant. The September offering was made pursuant to the Company’s effective shelf registration statement on Form S-3. The issued pre-funded warrants were classified as a component of permanent equity in the Company’s Consolidated Balance Sheets as they are freestanding financial instruments that are immediately exercisable, do not embody an obligation for the Company to repurchase its own shares, and permit the holders to receive a fixed number of shares of common stock upon exercise. All of the shares underlying the pre-funded warrants have been included in the weighted-average number of shares of common stock used to calculate net income/loss per share, basic and diluted, attributable to common stockholders as the shares may be issued for little or no consideration, are fully vested, and are exercisable after the original issuance date of the pre-funded warrants. As of December 31, 2025, none of the pre-funded warrants had been exercised. See Note 19 - Subsequent Events. |
