Forward-Looking Statements

This press release 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 future strategy and other statements that do not relate solely to historical facts. Forward-looking statements can be identified by words such as “opportunity,” “accelerate,” “increase,” “meet,” “enhance,” “deliver,” “achieve,” “will,” “would,” “could,” “should,” “continue,” “future,” 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 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 clubs, 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 indebtedness 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, general economic conditions and the other factors described in the Company’s annual report on Form 10-K for the year ended December 31, 2024 and the Company’s quarterly report on Form 10-Q for the quarter ended September 30, 2025, as well as the Company’s other filings with the Securities and Exchange Commission. 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 press release. 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.
