Forward Looking Statements This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act and Section 21E of the Exchange Act. Forward-looking statements include any statements about the Company's business, financial condition, operating results, plans, objectives, expectations and intentions, expansion plans, estimates of our total addressable market, our ability to successfully complete and realize the benefits of anticipated acquisitions, integration of acquired companies and any projections of earnings, revenue, EBITDA, Adjusted EBITDA or other financial items, such as the Company's projected capitation and future liquidity, and may be identified by the use of forward-looking terms such as "anticipate," "could," "can," "may," "might," "potential," "predict," "should," "estimate," "expect," "project," "believe," "plan," "envision," "intend," "continue," "target," "seek," "will," "would," and the negative of such terms, other variations on such terms or other similar or comparable words, phrases or terminology. Forward-looking statements reflect current views with respect to future events and financial performance and therefore cannot be guaranteed. Such statements are based on the current expectations and certain assumptions of the Company's management, and some or all of such expectations and assumptions may not materialize or may vary significantly from actual results. Actual results may also vary materially from forward-looking statements due to risks, uncertainties and other factors, known and unknown, including the risk factors described from time to time in the Company's reports to the U.S. Securities and Exchange Commission (the "SEC"), including without limitation the risk factors discussed in the Company's Annual Report on Form 10-K for the year ended December 31, 2023, and subsequent Quarterly Reports on Form 10-Q. Because the factors referred to above could cause actual results or outcomes to differ materially from those expressed or implied in any forward-looking statements, you should not place undue reliance on any such forward-looking statements. Any forward-looking statements speak only as of the date of this presentation and, unless legally required, the Company does not undertake any obligation to update any forward-looking statement, as a result of new information, future events or otherwise. This presentation may contain statistics and other data that in some cases has been obtained from or compiled from information made available by third-party service providers. The Company makes no representation or warranty, express or implied, with respect to the accuracy, reasonableness or completeness of such information. Use of Non-GAAP Financial Measures This presentation contains the non-GAAP financial measures EBITDA and Adjusted EBITDA, of which the most directly comparable financial measure presented in accordance with U.S. generally accepted accounting principles ("GAAP") is net income. These measures are not in accordance with, or alternatives to, GAAP, and may be calculated differently from similar non-GAAP financial measures used by other companies. The Company uses Adjusted EBITDA as a supplemental performance measure of our operations, for financial and operational decision-making, and as a supplemental means of evaluating period-to-period comparisons on a consistent basis. Adjusted EBITDA is calculated as earnings before interest, taxes, depreciation, and amortization, excluding income or loss from equity method investments, non-recurring and non-cash transactions, stock-based compensation, and APC excluded assets costs. Beginning in the third quarter ended September 30, 2022, the Company has revised the calculation for Adjusted EBITDA to exclude provider bonus payments and losses from recently acquired IPAs, which it believes to be more reflective of its business. The Company believes the presentation of these non-GAAP financial measures provides investors with relevant and useful information, as it allows investors to evaluate the operating performance of the business activities without having to account for differences recognized because of non-core or non-recurring financial information. When GAAP financial measures are viewed in conjunction with non-GAAP financial measures, investors are provided with a more meaningful understanding of the Company's ongoing operating performance. In addition, these non-GAAP financial measures are among those indicators the Company uses as a basis for evaluating operational performance, allocating resources, and planning and forecasting future periods. Non-GAAP financial measures are not intended to be considered in isolation, or as a substitute for, GAAP financial measures. Other companies may calculate both EBITDA and Adjusted EBITDA differently, limiting the usefulness of these measures for comparative purposes. To the extent this Presentation contains historical or future non-GAAP financial measures, the Company has provided corresponding GAAP financial measures for comparative purposes. The reconciliation between certain GAAP and non-GAAP measures is provided in the Appendix. The Company has not provided a quantitative reconciliation of applicable non-GAAP measures, such as the projected adjusted EBITDA and adjusted EBITDA margin in 2024 and in future years for planned acquisitions, to the most comparable GAAP measure, such as net income, on a forward-looking basis within this presentation because the Company is unable, without unreasonable efforts, to provide reconciling information with respect to certain line items that cannot be calculated. These items, which could materially affect the computation of forward-looking GAAP net income, are inherently uncertain and depend on various factors, some of which are outside of the Company's control.
