Management & Training Corporation is the third-largest private prison operator in the United States. Unlike GEO Group and CoreCivic (which are publicly traded), MTC is a privately held company. Its core businesses span corrections, education and training (including U.S. Job Corps centers), medical services, and economic/social development.

ICE Detention Operations

MTC currently operates five ICE detention facilities, including:

• Imperial Regional Detention Facility (Calexico, California) – ICE immigration detention center

Marana Facility Expansion (2026)

MTC is pursuing a significant expansion in Arizona:

• Purchased a shuttered private prison in Marana, Arizona for $15 million
• ICE posted notice of intent to award a sole-source contract to MTC to operate the facility
• Capacity: Documents describe between 513 and 775 detainees (male)
• Target activation: November 30, 2026
• Opposition: Pima County Board of Supervisors passed a resolution in February 2026 formally opposing the facility. Protests in March 2026.
• A federal order subsequently sought a major capacity increase at the proposed facility

ACLU FOIA Documents

MTC submitted contract proposals to ICE Requests for Information (RFI) to expand detention capacity, alongside GEO Group and CoreCivic. The ACLU noted that several MTC facilities have “a lengthy history of abusive conditions.”

Revenue

MTC is privately held and does not publicly report financials. Revenue estimates vary widely across sources (some estimates range from ~$855M to several billion, though these may include non-corrections divisions). The company manages both private prisons and U.S. Job Corps centers.
