PSYCHIATRIC SOLUTIONS COMPLETES ACQUISITION OF
HORIZON HEALTH CORPORATION

FRANKLIN, Tenn. (June 1, 2007) — Psychiatric Solutions, Inc. (“PSI”) (NASDAQ: PSYS) today announced that it has completed the acquisition of Horizon Health Corporation in a transaction valued at $426 million. The purchase price consisted of cash of $20 per share totaling $321 million and the repayment or assumption of Horizon’s outstanding debt. Horizon produced revenue of $297 million for the 12 month period ended February 28, 2007, primarily through the operation of 15 owned or leased inpatient behavioral health facilities with approximately 1,600 beds in 11 states.

     PSI financed the transaction and the cash tender of the 10.625% Senior Subordinated Notes due 2013 with an additional $225 million of borrowings under the term loan portion of its senior secured credit facilities, as well as the net proceeds of an offering of $250 million principal amount of Senior Subordinated Notes due 2015.

     Based on completing the Horizon transaction, PSI now expects its 2007 earnings per diluted share to be in a range of $1.44 to $1.47 excluding any one-time charges related to the tender of the 10.625% Senior Subordinated Notes. This increase reflects approximately $0.08 to $0.09 of accretion from the Horizon acquisition for the balance of 2007 offset by an approximate $0.05 increase in non-cash stock compensation expense and a higher diluted share count for 2007. PSI continues to expect the Horizon transaction to be accretive to its earnings per diluted share for the next 12 months by an amount in a range of $0.17 to $0.20. This updated guidance does not include the impact from any future acquisitions.

     Joey Jacobs, Chairman, President and Chief Executive Officer of PSI, remarked, “We are very pleased to have completed this transaction, which adds high-quality assets and employees to our operations. Consistent with our long-term record of successfully completing and integrating acquisitions, we see a significant, continuing opportunity to expand the market share and profitability of each of these facilities. We welcome the dedicated and skilled team members throughout Horizon to the PSI family.”
