For her service on the board, Ms. Pearson will be compensated in accordance with the Company’s non-employee director compensation policy. Ms. Pearson will be granted restricted stock units (“RSUs”) with a value of a pro rata portion of $155,000, such pro rata portion based on the number of days Ms. Pearson will serve until the next annual meeting of stockholders as compared to the number of days between that annual meeting and the immediately preceding annual meeting of stockholders, calculated by dividing the pro rata portion of $155,000 by the closing sale price per share of the Company’s common stock on the Nasdaq Global Market on the date of grant. These RSUs will be granted on March 9, 2026, and will vest in a single installment on the date of the Company’s 2026 annual meeting of stockholders, subject to the condition that Ms. Pearson remain a director as of that date.

Non-employee directors may elect to receive between 10% and 100% of their aggregate annual cash retainers in the form of RSUs, with the number of RSUs calculated by dividing the amount of the retainer payable on a certain date by the closing sale price per share of the Company’s common stock on the date of grant.
