Investor Presentation June 2023 1 Exhibit 99.1

The financial information presented in this presentation includes non-GAAP financial measures such as EBITDA, Segment EBITDA, Adjusted EBITDA, and Adjusted earnings per share to provide measures that we believe are useful to investors in evaluating the Company’s performance. These non-GAAP financial measures are supplemental measures of the Company’s performance that are neither required by, nor presented in accordance with GAAP. These financial measures should not be considered in isolation or as substitutes for GAAP financial measures such as net income or any other performance measures derived in accordance with GAAP. In addition, in the future, the Company may incur expenses or charges such as those added back to calculate these non-GAAP measures. The Company’s presentation of these non-GAAP measures should not be construed as an inference that the Company’s future results will be unaffected by similar amounts or other unusual or nonrecurring items. Same store sales refers to year-over-year sales comparisons for the same store sales base of both corporate-owned and franchisee-owned stores, which is calculated for a given period by including only sales from stores that had sales in the comparable months of both years. We define the same store sales base to include those stores that have been open and for which monthly membership dues have been billed for longer than 12 months. We measure same store sales based solely upon monthly dues billed to members of our corporate-owned and franchisee-owned stores. The non-GAAP financial measures used in our long-term growth targets will differ from their most directly comparable GAAP measures in ways similar to those in reconciliations the Company has previously provided in its disclosure with the Securities and Exchange Commission (SEC). We do not provide a reconciliation of growth targets for Adjusted EBITDA or Adjusted earnings per share to the most directly comparable GAAP measure because we are not able to predict with reasonable certainty the amount or nature of all items that will be included for the applicable period. Accordingly, a reconciliation of the Company’s growth targets for these non-GAAP measures to the most directly comparable GAAP measure cannot be made available without unreasonable effort. These items are uncertain, depend on many factors and could have a material impact on our Adjusted EBITDA and Adjusted earnings per share for the applicable period This presentation contains “forward-looking statements” within the meaning of the federal securities laws, which involve risks and uncertainties. Forward-looking statements include the Company’s statements with respect to expected future performance presented under the heading “3-Year Financial Targets” attributed to the Company’s Chief Financial Officer as well as other statements by other members of the Company’s management team in this presentation, including with respect to the Company’s growth opportunities, ability to create long-term value for our shareholders, long-term store and member growth, and other statements, estimates and projections that do not relate solely to historical facts. Forward-looking statements can be identified by words such as "believe," “expect,” “goal,” plan,” “will,” “prospects,” “future,” “strategy,” “projected” and similar references to future periods, although not all forward-looking statements include these identifying words. Forward-looking statements are not assurances of future performance. Instead, they are based only on the Company’s current beliefs, expectations and assumptions regarding the future of the business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of the Company’s control. Actual results and financial condition may differ materially from those indicated in the forward-looking statements. Important factors that could cause our actual results to differ materially include risks and uncertainties associated with the duration and impact of COVID-19, which has resulted and may in the future result in store closures and a decrease in our net membership base and may give rise to or heighten one or more of the other risks and uncertainties described herein, competition in the fitness industry, the Company’s and franchisees’ ability to attract and retain members, the Company's and franchisees' ability to identify and secure suitable sites for new franchise stores, changes in consumer demand, changes in equipment costs, the Company’s ability to expand into new markets domestically and internationally, operating costs for the Company and franchisees generally, availability and cost of capital for franchisees, acquisition activity, developments and changes in laws and regulations, our substantial increased indebtedness as a result of our refinancing and securitization transactions and our ability to incur additional indebtedness or refinance that indebtedness in the future, our future financial performance and our ability to pay principal and interest on our indebtedness, our corporate structure and tax receivable agreements, failures, interruptions or security breaches of the Company's information systems or technology, our ability to successfully integrate and realize the anticipated benefits from the Sunshine Acquisition, general economic conditions and the other factors described in the Company’s annual report on Form 10-K for the year ended December 31, 2022, and the Company’s other filings with the SEC. In light of the significant risks and uncertainties inherent in forward-looking statements, investors should not place undue reliance on forward-looking statements, which reflect the Company’s views only as of the date of this presentation. Except as required by law, neither the Company nor any of its affiliates or representatives undertake any obligation to provide additional information or to correct or update any information set forth in this release, whether as a result of new information, future developments or otherwise.
