Indemnification Arrangements

On July 30, 2025, our board of directors approved a new form of indemnification agreement (the “Indemnification Agreement”) to be entered into between the Company and each of our directors and certain officers. The Indemnification Agreement supersedes our previous form of indemnification agreement.

The Indemnification Agreement provides, among other things, that the Company will indemnify and advance expenses to the director or officer (the “Indemnitee”), to the fullest extent permitted by applicable law in effect on the date thereof or as amended to increase the scope of permitted indemnification, for any and all losses (including all interest and assessments and other charges in connection therewith) actually and reasonably incurred by the Indemnitee or on the Indemnitee’s behalf in connection with any proceeding in any way connected with, resulting from or relating to the Indemnitee’s status as a director or officer. The Indemnification Agreement also establishes various procedures, processes and requirements for the Indemnitee to exercise the provided indemnification and advancement rights.

The foregoing description of the Indemnification Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the form of Indemnification Agreement, which is attached hereto as Exhibit 10.3 to this report and incorporated herein by reference.
