### DIRECTOR COMPENSATION
The Human Capital and Compensation Committee performs an annual review of non-employee director compensation. Our director compensation philosophy is intended to offer compensation that attracts highly qualified non-employee directors and retain the leadership and skills necessary to build long-term shareholder value. Directors who are also our employees receive no additional compensation for serving on the Board of Directors.

#### Fiscal 2025
During fiscal 2025, our non-employee directors received an annual cash retainer of $65,000 and the following positions received additional cash retainers:

| Independent Chairman of the Board                        |     | $45,000 per annum |
| Lead Independent Director                                |     | 35,000 per annum  |
| Chairman of the Audit Committee                          |     | 25,000 per annum  |
| Chairman of the Human Capital and Compensation Committee |     | 20,000 per annum  |
| Chairman of the Nominating and Governance Committee      |     | 12,000 per annum  |
| Chairman of the Government Relations Committee           |     | 12,000 per annum  |
| Chairman of the M&A and Finance Committee                |     | 12,000 per annum  |

All of these retainers are paid in cash in quarterly installments. Directors are also reimbursed for their reasonable expenses incurred in connection with attendance at Board and committee meetings.

New non-employee directors are granted restricted stock unit awards in connection with their first election to the Board. These awards are granted by the Board of Directors and consist of restricted stock units for the number of shares of common stock equal to $225,000 divided by the average closing price of our common stock during the 30 calendar days prior to the date of grant. These awards vest as to 50% of the covered shares on each of the first two anniversaries of the date of grant.

Non-employee directors also receive annual restricted stock unit awards for the number of shares of common stock equal to $175,000 divided by the average closing price of our common stock during the 30 calendar days prior to the date of grant. These awards vest on the first anniversary of the date of grant. Non-employee directors are not eligible to receive an annual restricted stock unit award for the fiscal year in which they are first elected.

#### Compensation Deferrals
Effective for fiscal 2025, the Human Capital and Compensation Committee recommended, and the Board of Directors approved, a change in our compensation policy for non-employee directors to permit directors to elect to defer their
