The Company is not obligated to sell any Placement Shares under the Sales Agreement. Subject to the terms and conditions of the Sales Agreement, the Lead Agent will use commercially reasonable efforts, consistent with its normal trading and sales practices and applicable state and federal laws, rules and regulations and the rules of the Nasdaq Global Market (the “Exchange”), to sell the Placement Shares from time to time based on the Company’s instructions, including any price, time or size limits specified by the Company, subject to certain limitations. Under the Sales Agreement, the Lead Agent may sell Placement Shares by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act of 1933, as amended (the “Securities Act”) and as set forth in the “Plan of Distribution” section of the Prospectus forming part of the Registration Statement. The Placement Shares will be issued pursuant to the Company’s shelf registration statement on Form S-3 (File No. 333-291266) initially filed by the Company with the U.S. Securities and Exchange Commission (the “SEC”) on November 5, 2025 (the “Registration Statement”), and having become effective in accordance with the rules and regulations of the SEC on November 25, 2025, and related prospectus supplements to be prepared and filed pursuant to Rule 424(b) from time to time in connection with the offer and sale of Placement Shares. A prospectus supplement (the “Prospectus Supplement”), covering the offers and sales under the ATM Program will be filed with the SEC on the date hereof. The Company will pay the Lead Agent a commission up to 3% of the gross proceeds from each sale of Placement Shares and provide the Agent with customary indemnification and contribution rights. The Sales Agreement will be effective until the earlier of the issuance and sale of all of the Placement Shares issuable pursuant to the ATM Program and the date that the ATM Program is otherwise terminated pursuant to the terms of the Sales Agreement.
