On November 14, 2025, the Board approved an amendment and restatement of the Company’s Non-Management Director Compensation Plan (as amended, the “Plan”) to provide for additional compensation for the Board’s Lead Independent Director.

Under the amendment, effective as of November 14, 2025, the Lead Independent Director will receive an annual retainer of $30,000 in respect of such service (the “Lead Independent Director Retainer”), earned on a quarterly basis based on a calendar quarter and paid by the Company in arrears ($7,500 per quarter) no later than the fifteenth day following the end of each calendar quarter. The Lead Independent Director Retainer shall be prorated in the event that a Participant serves as the Lead Independent Director for a portion of any calendar quarter based on the number of days of service during such calendar quarter. The Lead Independent Director may elect that all or a specified percentage of the Lead Independent Director Retainer that would otherwise be payable in cash shall instead be paid in the form of fully vested Common Stock of the Company in accordance with the Plan.

The amendment and restatement of the Plan did not otherwise modify the compensation of the Company’s non-management directors.

A copy of the Plan is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.
