Leidos Holdings, Inc.

Leidos is an industry and technology leader serving government and commercial customers with smarter, more efficient digital and mission innovations. Headquartered in Reston, Virginia, with 50,000 global employees, we pursue strategic growth across five pillars: defense tech; energy infrastructure; cyber; mission and digital solutions; and managed health services. Our customers include the U.S. Department of War (“DoW”), the U.S. Intelligence Community, the U.S. Department of Homeland Security, the Federal Aviation Administration, the Department of Veterans Affairs, and many other U.S. civilian, state and local government agencies, foreign government agencies and commercial businesses.

Beginning in fiscal 2026, we realigned our business and operate in four reportable segments that are focused on specific, defined capability sets we bring to our customers. As a result of this change, prior year segment results and disclosures have been recast to reflect the current reportable segment structure. We now operate in the following reportable segments: Intelligence & Digital, Health, Homeland and Defense. We also separately present the unallocable costs associated with corporate functions as Corporate (see "Note 10–Business Segments").
