Leidos Shares Fall After Q1 Beat as Investors Weigh Defense Margin Pressure

Leidos Holdings Inc. (LDOS) traded at $128.03 on May 15, 2026, down about 14% from $148.81 before its first-quarter earnings release, despite results that topped Wall Street expectations. Management cited growth in intelligence and digital infrastructure, along with demand for defense products including the AGM-190A missile and unmanned surface vehicles. CEO Thomas Bell said revenue gains were supported by scaling AI-driven offerings across five growth areas, including managed health and energy resilience. Investor concern centered on Defense segment profitability, which management said was pressured by early-stage development programs and fixed-price contracts. Analysts are expected to focus in coming quarters on the conversion of defense and energy infrastructure awards into revenue, margin stabilization after investments and acquisitions, and execution of AI-enabled solutions across health and digital businesses.
