Leidos Holdings Inc. (LDOS) shares plummeted 5.21% during intraday trading on Tuesday, as the defense contractor reported fourth-quarter revenue that fell short of Wall Street estimates and issued full-year guidance below analyst expectations.

The company's revenue for the quarter came in at $4.21 billion, missing the consensus estimate of approximately $4.30 billion. The shortfall was attributed to the impact of a six-week U.S. government shutdown last year, which weighed on orders for the federal contractor. While adjusted earnings per share of $2.76 beat estimates, the revenue miss and a 2026 revenue guidance range of $17.5 billion to $17.9 billion—below the FactSet consensus of $17.92 billion—drove the stock lower.

The decline extended a pre-market drop, with shares having fallen over 4% earlier in the session following the earnings release, as investors reacted to the disappointing top-line results and cautious outlook.
