The GEO Group, Inc. Announces Discontinuation of its
Michigan Youth Correctional Facility Operations Contract

Friday September 30, 4:57 pm ET

BOCA RATON, Fla., Sept. 30 /PRNewswire-FirstCall/ — The GEO Group, Inc. (NYSE: GGI — News; “GEO”) was informed today that the Governor of the State of Michigan announced her decision to close GEO’s 480-bed Michigan Youth Correctional Facility (the “Facility”). The Michigan Department of Corrections will transfer the youthful offenders currently housed at the Facility to other prisons in the state of Michigan beginning next week. GEO and the state have agreed that the Facility’s operations will remain funded through October 14, 2005, when all inmates will have been transferred from the Facility.

George C. Zoley, Chairman and Chief Executive Officer of GEO, said, “On behalf of our employees and the entire Lake County community, we are deeply disappointed in the Governor’s decision. We believe that this is the wrong decision for the state of Michigan, the Lake County and Baldwin community, the local schools, and the dedicated employees and their families who are economically dependent on this critically needed facility. The decision by Michigan’s Governor to close this Facility runs contrary to what other states have recognized with respect to the important contributions that private corrections make to a state’s correctional system, as evidenced by our recent awards in the States of Florida and Indiana.”

As a result of the discontinuation of the Facility’s operations and a likely dispute with respect to the continuation of the Facility lease, GEO is adjusting its guidance for the fourth quarter of 2005 and the full year of 2006, including the impact of the proposed acquisition of Correctional Services Corporation, as follows: fourth quarter 2005 revenue range: $167 million to $174 million; fourth quarter 2005 earnings per share range: $0.31 to $0.34; 2006 revenue range: $725 million to $745 million; 2006 earnings per share range: $1.70 to $1.80. GEO is in the process of determining whether an impairment charge related to the closing of the Michigan Youth Correctional Facility is required and, if so, the appropriate timing of that charge.

(“GEO”) is a world leader in the delivery of correctional and detention management, health and mental health, and other diversified services to federal, state, and local government agencies around the globe.
