NON-GAAP FINANCIAL MEASURES This presentation includes references to non‐GAAP financial measures, including but not limited to Medical Margin and Adjusted EBITDA. We believe medical margin and Adjusted EBITDA help identify underlying trends in our business and facilitate evaluation of period-to-period operating performance of our operations by eliminating items that are variable in nature and not considered by us in the evaluation of ongoing operating performance, allowing comparison of our recurring core business operating results over multiple periods. We also believe Medical Margin and Adjusted EBITDA provide useful information about our operating results, enhance the overall understanding of our past performance and future prospects, and allow for greater transparency with respect to key metrics we use for financial and operational decision-making. We believe Medical Margin and Adjusted EBITDA or similarly titled non-GAAP measures are widely used by investors, securities analysts, ratings agencies, and other parties in evaluating companies in our industry as a measure of financial performance. Other companies may calculate Medical Margin and Adjusted EBITDA or similarly titled non-GAAP measures differently from the way we calculate these metrics. As a result, our presentation of Medical Margin and Adjusted EBITDA may not be comparable to similarly titled measures of other companies, limiting their usefulness as comparative measures Medical Margin and Adjusted EBITDA have limitations as analytical tools and should not be considered in isolation or as an alternative to GAAP measures or other financial statement data presented in agilon’s consolidated financial statements. Reconciliation of such non-GAAP measures to the applicable GAAP measures are set forth in the appendix.
