Accordingly, neither the Company nor any of its affiliates, advisers or representatives makes any representations as to the accuracy or completeness of that data or to update such data after the date of this presentation.

Preliminary Unaudited Selected Financial Data This presentation includes unaudited estimates regarding surgical case volumes, Revenues, Adjusted Revenues, Same-facility Revenues, Adjusted EBITDA, and Consolidated Cash and Cash Equivalents for the quarter ended June 30, 2020. These estimates are the responsibility of management and are subject to quarter-end adjustments in connection with the completion of our customary financial closing procedures, including management’s review and finalization and to accounting review procedures by our independent registered public accounting firm, which have not yet been performed. During the course of our review process, items may be identified that would require the Company to make adjustments, which could result in material changes to these preliminary unaudited estimated financial results. Consequently, the results should not be viewed as a substitute for the Company’s earnings release and Quarterly Report on Form 10-Q, which are expected to be released on August 5, 2020. Actual results may differ materially from our preliminary expectations. Confidential 2

Legal Disclaimer (continued) Non-GAAP Financial Measures This presentation contains certain non-GAAP financial measures, including Adjusted Revenue, Adjusted EBITDA, and Credit Agreement EBITDA. A “non-GAAP financial measure” is defined as a numerical measure of a company’s financial performance that excludes or includes amounts so as to be different than the most directly comparable measure calculated and presented in accordance with GAAP in the statements of income, balance sheets or statements of cash flow of the company. The Company presents non-GAAP financial measures when it believes that the additional information is useful and meaningful to investors. Non-GAAP financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similar measures presented by other companies. The presentation of non-GAAP financial measures is not intended to be a substitute for, and should not be considered in isolation from, the financial measures reported in accordance with GAAP. For additional information about our non-GAAP financial measures, and a reconciliation of certain non-GAAP financial measures to the most nearly comparable GAAP measures, see slides 23 and 24 of this presentation and the Company’s 10-K. The Company will provide a full GAAP reconciliation of final Adjusted Revenue and Adjusted EBITDA for the quarter ending March 31, 2020 when it reports its full second quarter results.
