Shares of private prisons rose Monday after newly elected President Donald Trump selected immigration hardliner Tom Homan as his “border czar.”

The Geo group And KernCivic rose more than 4% and nearly 8%, respectively, in premarket trading. Homan served as head of Immigration and Customs Enforcement during Trump’s first term.

Trump said on Truth Social on Sunday that Homan “will be in charge of all deportations of illegal aliens back to their countries of origin.” Homan will be responsible for the southern border, the northern border and all maritime and aviation security, Trump said.

Homan told a conservative conference in July that he would carry out “the largest deportation operation this country has ever seen” if Trump returns to office.

“With Trump returning to the White House, there will be a much tighter embrace of Geo Group and CXW,” Isaac Boltansky, an analyst at BTIG, told clients in a Nov. 6 note. The second Trump administration would allow contracts with the U.S. Marshalls Services and the Federal Bureau of Prisons, Boltansky said.

“More importantly, they would take a much more aggressive stance on border enforcement, which would impact these companies’ ICE business lines,” the analyst told clients.
