Compensation Discussion and Analysis The following table summarizes the FOS Metrics included in the 2024 AIP, the respective weightings for each metric and the Committee’s rationale for including such metric in the 2024 AIP design. In total, the FOS Metrics represent 70% of the 2024 AIP design. In early 2025, the Committee met to review the results of the 2024 FOS Metrics and Individual Performance Criteria, which were then combined to produce a Final 2024 AIP Performance Factor. *May vary from reported results to adjust for immaterial, non-recurring delays due to non-operational factors.

Compensation Discussion and Analysis The FOS Metrics, Individual Performance Criteria and their respective weightings, were communicated to the NEOs at the beginning of the performance period. Targets were set for each of the FOS Metrics and Individual Performance Criteria at levels that were designed to be reasonably achievable with strong management performance. Maximum performance levels were designed to be difficult to achieve in light of historical performance and the Company’s business forecast (including, among other things, consideration of market, economic and geopolitical factors) at the time the metrics were approved. 2024 AIP Performance Results The following table summarizes the Company’s 2024 AIP results with respect to the Company’s FOS Metrics. The results of each performance measure are expressed as a payout factor based on the percentage of the target performance level. For the 2024 AIP, performance greater than threshold but less than target results in a payout factor range of 50% - 99% of the target opportunity, and performance at or greater than target results in a payout range of 100% up to a maximum of 200% of the target opportunity, in each case using straight line interpolation between the points. Below threshold performance for each metric results in a payout of 0% for such metric. In the aggregate, the FOS Metrics of the 2024 AIP were achieved at 106% of target reflecting strong Company performance and outstanding management execution. * Due to the competitively sensitive nature of this measure, the threshold, target, maximum and result levels have all been indexed and reported as such.
