40 NOTICE OF 2025 ANNUAL MEETING AND PROXY STATEMENT

#### 2024 Compensation of Named Executive Officers
Historical Performance of Performance-Based Stock Units.

Half of PSUs granted in 2021 (which vested in 2024) were eligible to be earned based on the ratio of operating cash flow to adjusted net income ("OCF PSUs") over a three-year performance period beginning January 1, 2021 and ending December 31, 2023. Such OCF PSUs vested in March 2024 at 66.3% of target. PSUs granted in 2021 that were eligible to be earned based on three-year relative total stockholder return ("TSR") compared to the approved index were not earned, as performance was below threshold.

The following table shows the performance of the 2021 OCF PSUs:

| Financial Metric                                   |     | Threshold     
 (50% vesting) |    |   |     |    | Target         
 (100% vesting) |     |     | Maximum
