PSYCHIATRIC SOLUTIONS TERMINATES AGREEMENT TO ACQUIRE
ALTERNATIVE BEHAVIORAL SERVICES, INC.

FRANKLIN, Tenn. (October 10, 2006) — Psychiatric Solutions, Inc. (“PSI”) (NASDAQ: PSYS) today announced that it has terminated its previously announced definitive agreement to acquire Alternative Behavioral Services, Inc. (“ABS”), headquartered in Norfolk, Virginia, which was signed in May 2006. PSI reached its decision following significant effort to resolve the individual and cumulative effects of certain significant issues and changes that have a material adverse effect on ABS’s operations and financial results. Because PSI does not include any impact from future acquisitions in its earnings guidance, this termination will not affect its established earnings guidance for 2006.

Participants will have the opportunity to listen to the conference call over the Internet by going to www.psysolutions.com and clicking Investor Relations or by going to www.earnings.com.
