Pay Versus Performance
The Company’s compensation objectives and philosophy, which are discussed above, are designed to reward the contributions of its NEOs to the Company’s financial performance and provide compensation which is sufficient to attract and retain individuals who are motivated to contribute to the Company’s financial performance. To achieve these goals, the Company has implemented incentive plans which tie a significant portion of each NEOs compensation to pre-determined financial goals.
For the years ended December 31, 2025, December 31, 2024, and December 31, 2023, the most important financial performance measure used by the Company to link executive compensation actually paid to the executive officers was Adjusted EBITDA which is described in the accompanying footnotes below. For the years ended December 31, 2022 and 2021, the most important financial performance measure used by the Company to link executive compensation actually paid to the executive officers was Operating Results, which is described in the accompanying footnotes below.
The following table summarizes the executive compensation earned by the Company’s Principal Executive Officer (“PEO”), and other NEOs, the executive compensation actually paid to the Company’s PEO and other NEOs, and certain financial performance measures of the Company for the years ended December 31, 2025, 2024, 2023, 2022, and 2021.

On August 14, 2012, our common stock began trading on the NYSE. The Total Shareholder Return assumes that $100 was invested in our common stock and the common stock on each of the companies listed on The NYSE Healthcare Index (the Company’s Peer Group), on December 31, 2021 and that any dividends were reinvested.
(4)
Net income includes earnings attributable to both controlling and non-controlling interests.
(5)
Operating Results, a non-GAAP measure, equals net income attributable to our shareholders less, non-cash impairment charges, payments received from the federal government under the Corona virus Aid, Relief and Economic Security Act (“Relief Funds”), changes in revaluation of a put-right liability, clinic closure costs, loss on sale of a partnership, changes in fair value of contingent earn-out consideration, business acquisition related costs, costs related to a one-time financial and human resources systems upgrade, an income tax adjustment to revalue our deferred tax assets and liabilities to the most current statutory tax rate, and any allocations to non-controlling interests, all net of taxes. Operating Results per share also excludes the impact of the revaluation of redeemable non-controlling interest and the associated tax impact.
(6)
Adjusted EBITDA, a non-GAAP measure, is defined as net income attributable to our shareholders before interest income, interest expense, taxes, depreciation, amortization, non-cash impairment charges, Relief Funds, change in fair value of contingent earn-out consideration, changes in revaluation of put-right liability, equity-based awards compensation expense, clinic closure costs, impairment on assets held for sale, business acquisition related costs, costs related to a one-time financial and human resources systems upgrade, loss on sale of a partnership and other income and related portions for non-controlling interests.
The following table outlines the adjustments made to the compensation earned by the PEO and other NEOs, as presented in the Summary Compensation Table on page 30, to derive the compensation actually paid to the PEO and other NEOs.
