FRANKLIN, Tenn. (December 30, 2020) – Acadia Healthcare Company, Inc. (NASDAQ: ACHC) (“Acadia” or the “Company”) today announced that it has entered into a definitive agreement to sell its U.K. operations to Waterland Private Equity (“Waterland”) for a purchase price of approximately £1,078 million. The Company expects the sale to result in proceeds of approximately $1,350 million, net of transaction costs and the settlement of existing foreign currency hedging liabilities and based on the current GBP/USD exchange rate. The proposed transaction is expected to close in January 2021. The transaction includes the sale of the entirety of Acadia’s U.K. business operations, which are operated under the name of The Priory Group (the “Priory Business”).

Following a comprehensive process, we believe we have achieved this objective. We intend to use the proceeds to pay down debt and for other corporate purposes. We believe we are well positioned to meet the strong demand for mental health and substance use treatment across the U.S. We will continue to focus on delivering the highest level of patient care and advancing our position as a leading behavioral healthcare facilities operator in the U.S.”
