#### How Does Mercury Approach Board Refreshment?
To garner new ideas and perspectives, and to respond to the ever-changing needs of our stakeholders, the Board actively seeks candidates representing a range of tenures, areas of expertise, industry experience, and backgrounds. In 2020 the Board added Orlando P. Carvalho, in 2021 the Board added Debora A. Plunkett, in 2022 the Board added William L. Ballhaus and Howard L. Lance, in 2023 the Board added Gerard J. DeMuro, Roger A. Krone, and Scott Ostfeld, and in 2025 the Board added Jean Bua. Six of the eight independent directors that will continue on the Board following the Annual Meeting were elected during the last five years. The other two independent directors on the Board, Lisa S. Disbrow and Barry R. Nearhos, were added to the Board in 2017 and 2018, respectively.

Does Mercury have stock ownership guidelines for directors?

Each non-employee director is expected to own or control, directly or indirectly, shares of the Company's common stock equal to five times the value of the annual director cash retainer within five years of first becoming a non-employee director. Each non-employee director is expected to retain such investment in the Company as long as he or she is a non-employee director. Exceptions to this stock ownership guideline may be approved from time to time by the Board as it deems necessary to address individual circumstances. All of our non-employee directors are in compliance with the stock ownership guidelines.
