[F2]On March 1, 2025, the reporting person was granted 10,112 restricted stock units ("RSUs") vesting in three equal installments beginning on the first anniversary of the grant date, of which the first installment vested on March 1, 2026. RSUs convert into common stock on a one-for-one basis.
[F3]Payment of tax liability by withholding securities incident to vesting of RSUs.
[F4]In connection with the March 1, 2026 vesting of RSUs previously granted on March 1, 2023 and reported in Table 1, the reporting person's receipt of 3,153 shares of common stock was deferred pursuant to the reporting person's election under the Company's deferred compensation plan (the "Plan"), resulting in the reporting person's receipt of 3,153 shares of phantom stock.
[F5]These employee RSUs were issued pursuant to the Company's Amended and Restated 2023 Omnibus Incentive Plan ("LTI Plan") and will vest in three equal installments beginning on the first anniversary of the grant date.
[F6]These performance share awards were issued pursuant to the LTI Plan at 100% of target, have a three-year performance period, and will vest in all or in part upon achievement of performance metrics. Any awards that have not been vested and released at the end of the three-year performance period will be canceled.
[F7]Each share of phantom stock represents a right to receive one share of common stock or the cash value thereof. Shares of phantom stock become payable in accordance with the reporting person's distribution elections made pursuant to the Plan or upon the reporting person's termination of service, death, or disability. Subject to certain timing restrictions, the reporting person may transfer some or all of the shares of phantom stock into alternative investments under the terms of the Plan.
