  1. Each Restricted Share Unit (RSU) and Performance Share Unit (PSU) converts into common stock on a one-for-one basis. Reflects shares of Common Stock withheld by the Issuer to satisfy tax withholding obligations in connection with the vesting of the awards. The RSUs were granted on April 17, 2023 and are fully vested. 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, 2025. Based on the Compensation Committee's determination of achievement of these pre-established financial goals, 32%, 70% and 36% of the shares subject to the 2023, 2024 and 2025 financial periods, respectively, were earned and vested on April 17, 2026. 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, 2025. Based on the Compensation Committee's determination of achievement of the pre-established TSR goal, 130% of the shares subject to the PSU award were earned and vested on April 17, 2026. The number of PSUs earned and issued upon vesting was determined based on goals (set by the Compensation Committee on an annual basis) for each of the two fiscal years ended December 31, 2025. Based on the Compensation Committee's determination of achievement of these pre-established financial goals, 70% and 36% of the shares subject to the 2024 and 2025 financial periods, respectively, were earned and vested on May 15, 2026. The RSUs were granted on May 15, 2025 and vested as to one-half on May 15, 2026; the remaining one-half of the RSUs will vest in two equal semi-annual installments thereafter through May 15, 2027. The RSUs were granted on May 15, 2025 and vested as to one-third on May 15, 2026; the remaining two-thirds of the RSUs will vest in four equal semi-annual installments thereafter through May 15, 2028. The RSUs were granted on May 15, 2025 and vested as to one-half on May 15, 2026; the remaining one-half of the RSUs will vest in two equal semi-annual installments thereafter through May 15, 2027.

Restricted Share Unit (RSU) financial
"Each Restricted Share Unit (RSU) and Performance Share Unit (PSU) converts into common stock on a one-for-one basis."
Performance Share Unit (PSU) financial
"The number of PSUs earned and issued upon vesting was determined based on goals set by the Compensation Committee."
total shareholder return (TSR) financial
"Determined based on the Issuer's total shareholder return (TSR) compared to pre-established relative TSR goals."
Total shareholder return (TSR) measures how much an investment in a company's stock has grown over a specific period by combining the change in the share price and all dividends paid, expressed as a percentage. Think of it like tracking the total balance of a savings jar that increases both from added cash (dividends) and a rising sticker price on the jar (share price); investors use TSR to compare how well different stocks or managers deliver real, money-in-hand returns.
Compensation Committee financial
"Goals set by the Compensation Committee of the Issuer's Board of Directors on an annual basis."
A compensation committee is a group within a company's leadership responsible for setting and reviewing how much top executives and employees are paid, including salaries, bonuses, and benefits. It matters to investors because fair and effective pay decisions can influence a company's performance, leadership motivation, and overall governance, helping ensure that the company’s management is aligned with shareholders’ interests.
tax withholding obligations financial
"Reflects shares of Common Stock withheld by the Issuer to satisfy tax withholding obligations in connection with the vesting of the awards."
