In 2003, WCC management raised funds to repurchase all common stock held by G4S, and in 2004, the company changed its name to The GEO Group, Inc. In 2005, the company acquired Correctional Services Corporation (CSC) for $62 million in cash, and the assumption of $124 million in debt.

In February 2011, GEO acquired BI Incorporated, provider of electronic offender-tracking equipment and services, founded in 1978 and based in Boulder, Colorado, for $415 million. At the time, BI was the exclusive U.S. Immigration and Customs Enforcement (ICE) provider of Intensive Supervision and Appearance Program (ISAP) monitoring and supervision services.
