### DIRECTOR COMPENSATION
During 2024, the Company paid an annual cash retainer fee of $90,000 to each non-employee director, plus $65,000 for serving as the Lead Director, $25,000 for serving as the Chair of the Audit Committee, $20,000 for serving as the Chair of the Compensation and Human Capital Committee, and $15,000 for serving as the Chair of the Corporate Governance and Sustainability Committee, the Environmental, Health, and Safety Committee, or the Ad Hoc Cyber Committee. Directors are not paid for attendance at meetings, but non-employee directors are reimbursed for expenses they incur in connection with service on the Board and its committees. The Company does not provide any pension, deferred compensation, or charitable award programs to any of its non-employee directors. Any director who is an employee of the Company does not receive any additional compensation for serving as a director.

In addition to the cash compensation described above, immediately following the 2024 annual meeting of shareholders, each non-employee director either elected at the 2024 annual meeting or then continuing to serve as a director received 836 restricted shares of the Company’s common stock under the Company’s 2020 Stock Incentive Plan, having a grant date fair value of approximately $180,000. The share quantity awarded was calculated using the closing share price on May 21, 2024. All of the restricted shares granted to the non-employee directors immediately following the 2024 annual meeting are for services provided as non-employee directors through the start of the 2025 annual meeting of shareholders and will vest at that time provided such directors continue to serve as directors through such date.

The Corporate Governance and Sustainability Committee reviews non-employee director compensation on a periodic basis. The Corporate Governance and Sustainability Committee then recommends any changes in the compensation for
