Total Shareholder Return Vs Peer Group | Strong Relationship Between CAP and Certain Performance Measures • The Company’s CAP is well aligned with performance on key financial measures, including strong TSR that outperformed market indices and a 21% Adjusted EPS compounded growth rate, which reflects the Company’s focus on shareholder value creation. Despite this strong performance, as compared to fiscal 2021, CEO and non-CEO CAP declined by 7% and 1% respectively in fiscal 2023. ​ • Additionally, performance on other key metrics that drive long-term value creation, including free cash flow, adjusted EBITDA and segment adjusted operating margin, also increased meaningfully over this period. ​ • GAAP Net Income is influenced by a number of factors and can include items that are one-time in nature and is not exclusively used by investors to determine the long-term earnings power of the Company. As such, CAP and GAAP Net Income do not move in line with one another. ​ |  |
