Compensation Actually Paid vs. Total Shareholder Return | Relationship Between Pay and Performance Below are graphs showing the relationship of “compensation actually paid” (as defined by the SEC) and other information contained in the pay-versus-performance table. There were no adjustments required to be made to CEO compensation, as Mr. Clemente's compensation for the covered periods shown was entirely based in cash and he had no unvested equity awards outstanding during any of the covered periods. Relationship Between Compensation Actually Paid and TSR Compensation actually paid to NEOs has increased in line with total shareholder return due to the impact of the revaluation of unvested equity awards and a significantly higher stock price as of December 31, 2024 than in prior years. |  |
Compensation Actually Paid vs. Net Income | Relationship Between Compensation Actually Paid and Net Income Compensation actually paid to NEOs has increased in line with net income, as the Company generally utilizes both net income and Adjusted EBITDA as key performance metrics when determining executive compensation and both metrics have increased from 2022 through 2024. |  |
