On January 23, 2026, immediately following the consummation of the Bluejay Acquisition, the Company completed the private placement of 3,385,149 shares of the Company’s common stock (“PIPE Shares”) and pre-funded warrants to purchase 536,412 shares of the Company’s common stock (the “Warrant Shares”) for aggregate net proceeds of approximately $259.9 million, after estimated offering expenses of $8.6 million. The purchase price per PIPE Share was $68.48 and the purchase price per pre-funded warrant was $68.4799 (which equals the purchase price of a PIPE Share, less $0.0001, the exercise price of each Warrant Share).

Each pre-funded warrant has an exercise price equal to $0.0001 per underlying share of common stock. The pre-funded warrants are exercisable at any time after their original issuance and may be exercised at any time until exercised in full. The Company may not effect the exercise of any pre-funded warrants and the selling stockholder that holds pre-funded warrants (together with its affiliates and other attribution parties) may not exercise any portion of a pre-funded warrant to the extent that, immediately after giving effect to such exercise, the holder would own more than 9.99% of the Company’s outstanding common stock, which percentage may be increased or decreased at the holder’s option (not to exceed 19.99%) upon 61 days’ notice to the Company, subject to the terms of the pre-funded warrants. As of June 30, 2026, none of the Warrant Shares were exercised.

On August 12, 2025, the Company filed an automatic shelf registration statement on Form S-3 with the SEC, which became effective upon filing, pursuant to which the Company registered for sale from time to time in one or more offerings an unlimited amount of any combination of the Company’s common stock, preferred stock, debt securities and warrants, so long as the Company continues to satisfy the requirements of a “well-known seasoned issuer” under SEC rules. This automatic shelf registration statement will remain in effect for up to three years from the date it became effective. As of June 30, 2026, the Company had not issued any securities pursuant to the automatic shelf registration statement.

On November 2, 2023, the Company entered into a Sales Agreement (the “2023 Sales Agreement”) with Leerink and Cantor Fitzgerald & Co. (the “Sales Agents”), pursuant to which the Company may, from time to time, sell up to an aggregate amount of $200.0 million of its common stock through the Sales Agents in an “at-the-market” offering. The Company is not required to sell shares under the 2023 Sales Agreement. Sales of the Company’s common stock, if any, under the 2023 Sales Agreement may be made in any transactions that are deemed to be “at the market offerings” as defined in Rule 415 under the Securities Act. The Company will pay a given designated Sales Agent a commission of up to 3.0% of the aggregate gross proceeds of any shares of common stock sold through such Sales Agent pursuant to the 2023 Sales Agreement. As of June 30, 2026, the Company had not issued any securities pursuant to the 2023 Sales Agreement.
