Leidos Holdings Inc

Leidos, a member of the Fortune 500®, is a dynamic innovation company that is at the forefront of addressing the world’s most challenging issues in national security and health sectors. With a global workforce of approximately 48,000, Leidos is committed to developing smarter technology solutions, particularly for customers in highly regulated industries. We bring domain-specific capability and cross-market innovations to customers in each of these markets by leveraging five technical core capabilities: digital modernization, cyber operations, mission software systems, integrated systems and mission operations. Our customers include the U.S. Department of Defense ("DoD"), the U.S. Intelligence Community, the U.S. Department of Homeland Security, the Federal Aviation Administration, the Department of Veterans Affairs, National Aeronautics and Space Administration and many other U.S. civilian, state and local government agencies, foreign government agencies and commercial businesses.

Beginning in fiscal 2024, 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: National Security & Digital, Health & Civil, Commercial & International and Defense Systems. We also separately present the unallocable costs associated with corporate functions as Corporate (see "Note 10–Business Segments").
