#### Proxy Summary

#### Compensation Highlights
Our shareholders continue to show strong support for our pay-for-performance philosophy (receiving 99% of votes cast in favor of our compensation program during the 2024 Annual Meeting). We believe weighting a significant portion of our NEOs' compensation with performance-based compensation and value creation in the form of stock appreciation aligns with our shareholders' expectations. With these expectations in mind, the HR Committee designed a compensation package for the CEO that was 84% at risk and for the other NEOs 67% at risk.

The HR Committee modified the prior year's compensation program to reflect the priorities of the business and its shareholders. Under the Company's annual incentive program (the "AIP") for 2024 (the "2024 AIP"), we modified the Corporate Plan to mirror the three Group President Plans to further focus management on margin expansion across the enterprise. We continued to align management's interest with those of our shareholders by linking the payout of the performance-based portion of our long-term compensation program to our financial performance and our Total Shareholder Return ("TSR") performance relative to the S&P SmallCap 600 Index ("rTSR").
