Stockholders’ Equity Stockholders’ Equity
Common Stock and Pre-funded Warrants
In April 2025, the Company entered into an exchange agreement with existing stockholders to exchange an aggregate of 667,500 shares of the Company’s common stock for pre-funded warrants to purchase an aggregate of 667,563 shares of the Company’s common stock at an exercise price of $0.001 per share. The exchange was executed to facilitate the investor’s beneficial ownership thresholds. The exchange was accounted for as an equity-for-equity transaction. The Company derecognized the common shares and recognized an equivalent value in pre-funded warrants, with no gain or loss recognized.
At-The-Market Offering of Shares
In August 2025, the Company entered into an at-the-market (“ATM”) sales agreement (the “Sales Agreement”) with Leerink Partners, LLC (“Leerink”), as sales agent, pursuant to which the Company may offer and sell, from time to time, shares of the Company’s common stock with an aggregate price up to $150.0 million through Leerink. During the three months ended June 30, 2026, the Company sold 209,529 shares of the Company’s common stock pursuant to the Sales Agreement, and received $5.9 million in net proceeds after deducting commissions and other offering expenses. As of June 30, 2026, the remaining amount authorized for sale under the Sales Agreement was $112.9 million.
In connection with the Sales Agreement, the Company incurred approximately $0.9 million of offering costs, of which $0.2 million was deferred. The deferred offering costs are recognized ratably as a reduction to additional paid-in-capital as shares are sold under the Sales Agreement. As of June 30, 2026, approximately $0.2 million of deferred offering costs remained on the balance sheet.
Pre-funded Warrants
The Company has pre-funded warrants outstanding to purchase an aggregate of 6,792,559 shares of the Company’s common stock as of June 30, 2026. The pre-funded warrants are exercisable at any time for exercise prices ranging from $0.000001 to $0.001, except that the pre-funded warrants cannot be exercised by a holder if, after giving effect thereto, such holder would beneficially own more than 9.99% of the Company’s outstanding common stock, subject to certain exceptions. However, any holder may increase or decrease such percentage to any other percentage (not in excess of 19.99%) upon at least 61 days’ prior notice from the holder to the Company. The holders of the pre-funded warrants will not have the right to vote the shares underlying the pre-funded warrants on any matter except to the extent required by Delaware law.
