bors, Inc. is a Massachusetts corporation, and by statute all public Massachusetts corporations have a staggered board of directors, with either two or three classes of directors, unless the corporation elects to be exempt from this statutory requirement by vote of its board of directors or of two-thirds of each class of stock outstanding. The Board has not elected to exempt, or to recommend that the shareholders exempt, the Company from this statutory requirement because the Board believes that a staggered board promotes continuity and stability.

Alan S. McKim, the Company’s founder, serves as the Executive Chairman of the Board and has held this role since the Company’s formation in 1980. Mr. McKim served as the Company's Chief Executive Officer and President through March 31, 2023, at which point the Board appointed Michael L. Battles, formerly the Company’s Chief Financial Officer, and Eric W. Gerstenberg, formerly the Company’s Chief Operating Officer, as the Co-Chief Executive Officers and Co-Presidents of the Company. Mr. McKim remains a director of the Company as the Executive Chairman of the Board and, since March 31, 2023, has served as the Company’s Chief Technology Officer. As of August 29. 2024, the Board expanded the size of the Board from eleven to thirteen members and elected both Mr. Battles and Mr. Gerstenberg to the Board as Class III directors.

The Board has a lead independent director, Edward G. Galante (the “Lead Director”). Mr. Galante was initially nominated as Lead Director by the Board’s Corporate Governance and Sustainability Committee and elected by the full Board in May 2022. Mr. Galante has served as a director of the Company since 2010.
