Boca Raton, Fla. — March 13, 2006 — The GEO Group, Inc. (NYSE: GGI) (“GEO”) today reported a fourth quarter 2005 GAAP loss of $0.8 million, or $0.08 per share, based on 10.0 million shares outstanding, compared with $5.2 million, or $0.53 per share, based on 9.8 million shares outstanding, in the fourth quarter of 2004. GAAP Net income for 2005 was $7.0 million, or $0.70 per share, based on 10.0 million diluted weighted average shares outstanding, compared with $16.8 million, or $1.73 per share, based on 9.7 million diluted weighted average shares outstanding, for 2004.

Fourth quarter 2005 pro forma earnings were $3.6 million, or $0.36 per share, compared with pro forma earnings of $5.2 million, or $0.52 per share for the fourth quarter of 2004.

Fourth quarter 2005 pro forma earnings results exclude an international tax benefit of $8.5 million, or $0.85 per share, related to certain tax law changes in Australia and South Africa, and an after-tax net gain of $0.5 million, or $0.05 per share, from discontinued operations which includes the gain on sale of GEO’s 72-bed Atlantic Shores Hospital in Fort Lauderdale, Florida on January 1, 2006.

George C. Zoley, Chairman and Chief Executive Officer of GEO, said: “We have taken corrective action to address several challenges which impacted our financial performance throughout the entire year. These challenges included a decline in the inmate population at our San Diego, California Facility, the closure of our Baldwin, Michigan Facility, and unanticipated employee healthcare costs. Despite these challenges and several one-time charges during the fourth quarter, which included a non-cash impairment charge related to our Michigan Facility, job reclassification expenses, and start-up costs related to our most recent contracts in Indiana and New Mexico, we achieved strong pro-forma quarterly results of $0.36 earnings per share.

“As result of our efforts, we have effectively overcome the challenges that impacted our performance in 2005, and we are now poised to have a strong financial year in 2006. We are therefore raising our financial guidance for 2006. We are particularly pleased with the signing of a new 10-year, fixed-payment contract for our San Diego, California Facility, which eliminates any future financial risks associated with inmate occupancy fluctuations. We also remain optimistic of our new business development prospects and the additional upside that they present in 2006 and beyond,” Zoley added.

Financial Guidance
GEO is raising its previously issued earnings guidance for 2006 by $0.05 per share to a range of $1.75 to $1.85 per share. GEO is raising its previously-issued revenue guidance for 2006 by $2.0 million to a range of $729 million to $745 million.

GEO is revising its financial guidance for the first quarter of 2006. GEO is increasing its first quarter 2006 revenue guidance by $2.0 million to a range of $182 million to $186 million and its first quarter 2006 earnings guidance by $0.05 per share to a range of $0.29 to $0.31 per share.

GEO is maintaining its previously issued guidance for the remaining quarters of 2006. GEO estimates second quarter 2006 revenues to be in the range of $181 million to $185 million and second quarter 2006 earnings per share to be in the range of $0.43 to $0.45. GEO estimates third quarter 2006 revenues to be in the range of $181 million to $185 million and third quarter 2006 earnings per share to be in the range of $0.53 to $0.55. GEO estimates fourth quarter 2006 revenues to be in the range of $185 million to $189 million and fourth quarter 2006 earnings per share to be in the range of $0.50 to $0.54.

In addition, GEO is providing the following EBITDA and EBITDAR guidance for 2006. GEO estimates year-end 2006 EBITDA to be in the range of $72 million to $76 million and year-end 2006 EBITDAR to be in the range of $98 million to $102 million.
