Acadia Healthcare Secures Requisite Consents

to Amend its Indenture Related to its 12.875% Senior Notes due 2018

FRANKLIN, Tenn. - June 18, 2014 — Acadia Healthcare Company, Inc. (NASDAQ: ACHC) (the “Company”) today announced that it has received the requisite consents in connection with its consent solicitation commenced on June 9, 2014 relating to an amendment (the “Amendment”) to the indenture (the “Indenture”) governing its 12.875% Senior Notes due 2018 (the “Notes”).

Ipreo LLC, the information and tabulation agent for the consent solicitation, advised the Company that as of the expiration of the consent solicitations at 5:00 p.m., New York City time, on June 17, 2014, the Company had received consents that had not been withdrawn in respect of a majority in aggregate principal amount of the Notes outstanding as of the record date. Following the receipt of the requisite consents from holders of the Notes, the Company executed a Supplemental Indenture dated as of June 17, 2014 effecting the Amendment (the “Supplemental Indenture”) and will pay a consent fee to the holders of the Notes who consented to the Amendment. The Supplemental Indenture binds all holders of the Notes and their transferees.

The Amendment increases the permitted Secured Leverage Ratio (as defined in the Indenture) contained in clause (29) of the definition of “Permitted Liens” in Section 1.01 of the Indenture from 3.0 to 1.0 to 3.5 to 1.0. The Amendment, as evidenced by the Supplemental Indenture, will enable the Company to incur additional secured indebtedness, thereby affording the Company greater financial flexibility.

Jefferies LLC acted as the solicitation agent and Ipreo LLC acted as the information and tabulation agent in connection with the consent solicitation. Additional information concerning the terms of the consent solicitation may be obtained from Ipreo by holders (as of the record date) of the Notes. Ipreo may be contacted at (888) 593-9546 (toll free) or (212) 849-3880.
