The Shares are being sold by the Company to the several underwriters named in the underwriting agreement, dated June 4, 2026 (the “Underwriting Agreement”), by and among the Company and the several underwriters named therein. The terms of the Shares are set forth in the certificate of designations (the “Certificate of Designations”) to be filed by the Company with the Secretary of State of the State of Delaware in connection with this offering.
