Geo Group Inc's stock plunged as much as 11.17% in pre-market trading on Thursday, following the release of the company's disappointing fourth-quarter earnings results on Wednesday evening.

The private prison operator reported adjusted net income of $18.2 million for the quarter, significantly missing analysts' consensus estimate of $30.6 million. While revenue of $607.7 million was roughly in line with expectations, the weaker-than-expected bottom-line performance appears to have rattled investors.

Geo Group also provided full-year 2025 guidance for adjusted EBITDA in the range of $460 million to $485 million. The company cited ongoing operational challenges and inflationary pressures as headwinds impacting profitability.
