Globalstar's stock tumbled 5.93% in pre-market trading on Friday following the release of its fourth-quarter 2025 financial results.

The satellite communications company reported a net loss of $11.618 million for the quarter, with an operating loss of $371 thousand and a pretax loss of $9.591 million. Earnings per share came in at -$0.11. A key performance metric, adjusted EBITDA, was $32.368 million, falling short of the IBES estimate of $35.3 million.

The company also provided its full-year revenue outlook, projecting between $280 million and $305 million. The earnings miss, particularly on adjusted EBITDA, appears to be the primary driver behind the sharp pre-market decline as investors react to the weaker-than-expected quarterly performance.
