Higginson, that he would be retiring and will not stand for re-nomination as a director at the next Annual Meeting of Shareholders (the “Annual Meeting”), which is expected to be held in Spring 2026.

The Board expressed its sincere appreciation for Mr. Higginson’s outstanding service to the Company and its shareholders for nearly 30 years.
