In connection with the foregoing changes, the Company’s Board of Directors voted on October 29, 2025 to expand the size of the Board from seven directors to nine directors, and to elect Mr. te Boekhorst and Timothy C. Fiori (the Company’s Chief Financial Officer) as directors. The Company’s Board of Directors also voted to elect Mr. Fiori as Secretary and Treasurer of the Company to fill the vacancies created by Mr. Brigham’s resignation.
