Explanation of Responses:

Id Content
F1 Each Performance Share Unit (PSU) converts into common stock on a one-for-one basis.
F2 The number of PSUs earned and issued upon vesting was determined based on goals (set by the Compensation Committee of the Issuer's Board of Directors (the "Compensation Committee") on an annual basis) for each of the three fiscal years ended December 31, 2024. Based on the Compensation Committee's determination of achievement of these pre-established financial goals, 32% and 70% of the shares subject to the 2023 and 2024 financial periods, respectively, were earned and vested on March 15, 2025, and no shares were earned for the 2022 performance period and were forfeited.
F3 Reflects shares of Common Stock withheld by the Issuer to satisfy tax withholding obligations in connection with the vesting of the PSUs.
F4 The number of PSUs earned and issued upon vesting was determined based on the Issuer's total shareholder return (TSR) compared to pre-established relative TSR goals, based on the TSR of a peer index of companies (set by the Compensation Committee at the time of grant) over the three fiscal years ended December 31, 2024. Based on the Compensation Committee's determination of achievement of the pre-established TSR goal, 100% of the shares subject to the PSU award were earned and vested on March 15, 2025.
