Common Stock | 9. Common Stock ​ Securities Purchase Agreement On November 12, 2025, the Company entered into a securities purchase agreement (the “Purchase Agreement”) with certain institutional and accredited investors (each, a “Purchaser” and collectively, the “Purchasers”) for a private placement of an aggregate of (i) 708,428 shares (the “Shares”) of the Company’s common stock at a purchase price of $8.52 per share, and (ii) pre-funded warrants to purchase up to an aggregate of 1,815,049 shares of common stock at a purchase price of $8.519 per pre-funded warrant, which represents the per share purchase price of the Shares less the $0.001 per share exercise price for each pre-funded warrant. The pre-funded warrants are exercisable at any time after the date of issuance and will not expire. The offering closed on November 14, 2025. Proceeds from the offering, net of placement agent’s fees and other offering expenses, were $20.3 million. On December 11, 2025, the Shares and pre-funded warrants were effectively registered with the SEC. Pre-Funded Warrants The rights and privileges of the pre-funded warrants issued under the offering are set forth in the warrant agreement between the Company and each of the respective warrant holders. The pre-funded warrants are exercisable at the option of the warrant holder at any time and do not expire. Pre-funded warrants do not provide any of the rights or privileges provided by the Company's common stock, including any voting rights, until the pre-funded warrants are exercised and settled in underlying shares of common stock. ​ The Company evaluated the pre-funded warrants issued under the offering and concluded the warrants are indexed to the Company's common stock, meet the criteria to be classified as equity and are not subject to remeasurement. The proceeds received from the issuance of the pre-funded warrants were recorded as additional paid-in capital. The Company issued 117,371 shares of common stock upon the exercise of pre-funded warrants during the year ended December 31, 2025. As of March 31, 2026, pre-funded warrants to purchase up to an aggregate of 1,697,678 shares of common stock remained outstanding. ​ At-The-Market Offering Agreement On December 19, 2025, the Company entered into an at-the-market offering agreement (the “Wainwright ATM Agreement”) with H.C. Wainwright & Co., LLC (the “Agent”), pursuant to which the Company may sell, from time to time, up to an aggregate sales price of $14.5 million of its common stock, through the Agent. Actual sales will depend on a variety of factors to be determined by the Company from time to time, including, among other things, market conditions, the trading price of the common stock, capital needs and determinations by the Company of the appropriate sources of funding for the Company. During the three months ended March 31, 2026, 99,446 shares of common stock were sold under the Wainwright ATM Agreement for net proceeds of approximately $1.2 million.
