Steve Mitchell-US PRESSWIRE
A private prison company, as in a private company that sells prisons.
From OwlAccess.com's Chuck King, who reports Florida Atlantic is soon to announce its new stadium's naming rights have been bought by a company called the GEO Group:
The GEO Group is a leader in privatizing correctional facilities. Its CEO, George Zoley, holds bachelor's and master's degrees from FAU. He has served as a member of FAU's Board of Trustees and was at one point the Board's chairman.
The Miami Herald notes FAU's president doesn't really want to talk about it right now:
FAU President Mary Jane Saunder initially agreed to talk about the news, but after hearing questions about the immigration detention center, a university spokesperson said they would have to return the call later. At press time, the university had stopped responding to El Nuevo Herald's calls.
But in a press release sent out earlier on Tuesday, Saunder praised GEO's philanthropic gesture of making the largest donation the university's athletic department has ever received.
More on the GEO Group, from Wikipedia:
A full scale prisoner uprising occurred on April 24, 2007 at the Geo Group-operated New Castle Correctional Facility in Indiana. The Fort Wayne News-Sentinel reported that "Authorities were investigating whether the six-hour fracas that involved about 500 offenders started Tuesday afternoon because some of the newly arrived prisoners from Arizona were upset about their treatment at the medium-security men's prison."
Between 2005 and 2009, at least eight people had died at the Geo Group-operated George W. Hill Correctional Facility in Delaware County, Pennsylvania, the state's only privately run jail. Several of those deaths resulted in lawsuits by family members who say the facility did not provide adequate medical care or proper supervision for offenders. On December 31, 2008, Geo pulled out of operations at this facility, "citing underperformance and frequent litigations" as the reasons.
In 2008, Sandy Morgan, a schizophrenic woman who suffered from a thyroid condition died at the Delaware County jail where she had been held for six weeks. Family members said she did not receive her medication during her incarceration.
On April 25, 2008, Kenneth Keith Kallenbach died from cystic fibrosis, an inherited chronic disease after being denied his medication. He had been housed at the jail since mid-March. Kallenbach's mother, Fay, said her son called her a week before his death, asking her to intervene and help him receive better treatment.
An inmate in 2008 claimed he was denied access to dental care for a cavity, and as a result it festered into an ulcer that burst open requiring three surgeries.
In November 2010 plaintiffs filed a federal lawsuit against the agencies that operate and own the Walnut Grove Youth Correctional Facility, saying that the prison authorities allowed abuses and negligence to occur at the facility. The lawsuit states that prison guards engaged in sexual intercourse with the prisoners and smuggled illegal drugs into the facilities, and that prison authorities denied education and medical care. As of that month the prison has about 1,200 prisoners ages 13-22; the lawsuit says that half of the prisoners are incarcerated for nonviolent offenses. Weeks prior to the filing of the lawsuit, United States Department of Justice officials informed Governor of Mississippi Haley Barbour that the department had started an investigation concerning the prison. GEO settled the lawsuit in February 2012 and it was agreed to move the remaining youths from the prison to more suitable locations that conform to juvenile standards.  Former Walnut Grove YCF warden and 8-term mayor, William Grady Sims, resigned and pleaded guilty to removing a female inmate to a motel for sex and pressuring her to lie about it. He faces up to 20 years in Federal prison. Sims also owned 18 vending machines inside the prison. 
Was gonna make a LOCKDOWN DEFENSE joke here, but after reading all that, I don't feel like joking about anything. This is the worst thing.
