The GEO Group sticks to its convictions, and it relies on them to generate business. The real estate investment trust (REIT) is one of the largest correctional systems in the US with operations in more than 30 states and electronic monitoring services in every state. Its worldwide operations include some 130 maximum-, medium-, and minimum-security correctional, detention (including immigrant detention), and mental health facilities with roughly 95,000 beds. It also conducts community supervision of more than 210,000 offenders and pretrial defendants. Furthermore, GEO runs educational, rehabilitative, and vocational training programs at its facilities. Its GEO Care unit provides mental health and residential treatment services for parolees, probationers, and pretrial defendants. About 90% of GEO's revenue derives from the US.
