Mar. 3, 2011 (Business Wire) — America Service Group Inc. (NASDAQ: ASGR), the parent company of PHS Correctional Healthcare, Inc., and Valitás Health Services, Inc., the parent company of Correctional Medical Services, Inc., announced today the signing of an agreement and plan of merger (the “Merger Agreement”) under which the two companies would be combined, bringing together two leading companies in the correctional healthcare field – America Service Group’s PHS Correctional Healthcare and Valitás’ Correctional Medical Services. Upon completion of the transaction, the combined company will have approximately 11,000 employees and independent contractors and will serve more than 400 correctional facilities. The combined company’s annual revenues are expected to total approximately $1.4 billion for 2011.

Pursuant to the terms of the Merger Agreement, Valitás will acquire America Service Group for cash consideration of $26.00 per share, or approximately $250 million, representing a 48.7% premium to the closing price of America Service Group’s stock on March 2, 2011, the last day of trading prior to the announcement of the Merger Agreement.

The transaction is subject to the approval of America Service Group’s stockholders and other customary closing conditions, including the satisfaction of governmental and regulatory approval requirements. The boards of directors of both companies have unanimously approved the Merger Agreement, and the board of directors of America Service Group recommends that its stockholders adopt the merger agreement.

America Service Group does not intend to disclose developments with respect to the solicitation process unless and until the board of directors has made a decision with respect to a potential superior proposal.

In commenting on the announcement, Rich Hallworth, President and Chief Executive Officer of America Service Group, said, “We believe this combination creates a new organization that will bring together the best people in our industry to serve our clients and patients and provides the best value to states and counties seeking to wisely use taxpayer dollars by privatizing their correctional healthcare facilities. The new company will have enhanced scale, broad service offerings, industry leading clinical approaches and growth opportunities for our employees.”

Richard H. Miles, Chairman and Chief Executive Officer of Valitás Health Services, Inc., added, “This combination will be good for the state and local governments we serve, providing them with greater access to outstanding talent and expertise in the specialized field of correctional healthcare.

Mr. Hallworth added, “I want to assure our clients that there will be no disruption in our services during the pendency of the transaction or afterward. We are keenly aware and sensitive to the needs of our clients, security personnel and patients to consistently deliver services under our respective contracts. Both companies are totally committed to maintaining consistency among those staff members who work in correctional facilities and in direct support of our contracts with corrections agencies. We do not anticipate making changes to these personnel or direct support staff members as we ensure continuity of services and care.”

The corporate headquarters for the combined company will be in Brentwood, Tennessee, while the operational headquarters will be in St. Louis, Missouri.
