 in Appendix B for the final 2024 amounts used in determination of incentive compensation achievement. The shares underlying the 2023 Performance Awards that were earned based on 2024 performance began to vest on March 15, 2025 and will continue to vest annually through March 15, 2028, subject to continued employment. The remaining 41.7% of the performance shares underlying the 2023 Performance Award that were eligible to be earned based on Adjusted EBITDA Margin and 100% of the performance shares underlying the 2023 Performance Award that were eligible to be earned based on Adjusted ROIC were forfeited as the C&HC Committee determined that we did not achieve the threshold level of Adjusted ROIC performance in 2024.

On March 15, 2025, the C&HC Committee granted performance shares (“2025 Performance Awards”) to each of the NEOs, other than Mr. McKim who does not participate in annual equity grants. The 2025 Performance Awards will be earned based on achievement of Adjusted EBITDA and Adjusted EBITDA margin metrics (each weighted at 50%) when compared to the Company’s performance solely in 2026. The 2025 Performance Awards are not eligible for early achievement. Further, each of the metrics approved by the C&HC Committee includes a threshold, target, and maximum level of achievement which payout at 50%, 100%, and 200% respectively. To the extent that the 2026 Performance Awards are earned, shares will vest 50% on March 15, 2027 and 50% on March 15, 2028.
