Cautionary Note Regarding Forward-Looking Statements

This Current Report on Form 8-K and the exhibits furnished herewith contain “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act, including statements related to the Company’s strategy, growth and anticipated operating results. Generally, words such as “may,” “will,” “should,” “could,” “anticipate,” “expect,” “intend,” “estimate,” “plan,” “continue” and “believe” or the negative of or other variation on these and other similar expressions identify forward-looking statements. These forward-looking statements are made only as of the date of this report. The Company does not undertake to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. Forward-looking statements are based on current expectations and involve risks and uncertainties, and the Company’s future results could differ significantly from those expressed or implied by its forward-looking statements. Factors that may cause actual results to differ materially include, without limitation, (i) potential difficulties in successfully integrating the operations of acquired facilities or realizing the expected benefits and synergies of facility expansions, acquisitions, joint ventures and de novo transactions; (ii) the Company’s ability to add beds, expand services, enhance marketing programs and improve efficiencies at its facilities; (iii) potential reductions in payments received by the Company from government and commercial payors, including because of the significant changes to Medicaid financing mechanisms introduced by the One Big Beautiful Bill Act (the “OBBBA”) enacted on July 4, 2025; (iv) the occurrence of patient incidents, governmental investigations, litigation and adverse regulatory actions, which could adversely affect the price of the Company’s common stock and result in substantial payments and incremental regulatory burdens; (v) changes in expectations resulting from actuarial and other reviews of the Company’s liability reserves and other aspects of its business; (vi) the risk that the Company may not generate sufficient cash from operations to service its debt and meet its working capital and capital expenditure requirements; (vii) potential disruptions to the Company’s information technology systems or a cybersecurity incident; and (viii) potential operating difficulties, including, without limitation, disruption to the U.S. economy and financial markets; reduced admissions and patient volumes, including, without limitation, due to the OBBBA’s introduction of work or community engagement requirements in the Medicaid expansion population; increased costs relating to labor, supply chain and other expenditures; changes in competition and client preferences; and general economic or industry conditions that may prevent the Company from realizing the expected benefits of its business strategies. These factors and others are more fully described in the Company’s periodic reports and other filings with the Securities and Exchange Commission.
