 Margin |     | 19.4%     |     | 19.5%  |

Achievement of each performance metric is determined independently. Shares underlying the 2024 Performance Award are earned based upon achievement of target (100% payout) or threshold (50% payout) metric, for one or both of the metrics, based on Company results in 2025. Such earned shares vest in four equal annual installments beginning on March 15, 2026 (subject to continued employment). Furthermore, shares can be earned earlier if target (100% payout) goals were met based on the Company results in 2024, in which case earned shares would vest in five equal annual installments beginning on March 15, 2025 (subject to continued employment). If the Company does not achieve at least the threshold level for a particular metric of the 2024 Performance Awards by December 31, 2025, all of the performance shares awarded under the 2024 Performance Award that are eligible to be earned based on achievement of that metric will be forfeited.

Performance shares granted have a value equal to a percentage of the individual’s annual base salary. The following table sets forth the 2024 Performance Awards granted to the NEOs, which were granted on February 1, 2024:
