Leidos Holdings Business Summary

Leidos Holdings, Inc. (LDOS) operates as a premier science and technology solutions provider, primarily generating revenue through high-value service contracts and integrated systems for the U.S. government and international agencies. The company’s business model is organized into four primary segments as of early 2026: National Security & Digital, Health & Civil, Commercial & International, and Defense Systems. These divisions provide critical services ranging from cybersecurity and digital modernization to managed health services and advanced maritime autonomy. Leidos maintains a dominant market position as one of the largest federal IT prime contractors, leveraging its "NorthStar 2030" strategy to integrate "Trusted Mission AI" across its portfolio. It competes directly with major industry peers such as Booz Allen Hamilton, CACI International, Science Applications International Corporation (SAIC), and L3Harris Technologies, distinguishing itself through superior revenue scale and a robust $47.7 billion backlog. Originally founded in 1969 by Dr. J. Robert Beyster as Science Applications International Corporation (SAIC), the company rebranded as Leidos following a 2013 strategic spin-off. The current leadership team is led by CEO Thomas A. Bell, who joined in 2023 with an extensive pedigree from Rolls-Royce and Boeing. In January 2026, the company further strengthened its technical bench by appointing Theodore "Ted" Tanner Jr. as Chief Technology Officer; Tanner brings a high-profile background from BigBear.ai, IBM Watson Health, Apple, and Microsoft, holding 18 patents in AI and machine learning. Financial oversight is managed by CFO Christopher Cage, a veteran of the firm since 1996. The board is chaired by Robert S. Shapard and includes notable figures such as former Acting Secretary of Defense Patrick Shanahan, while institutional stability is anchored by major shareholders including Vanguard and BlackRock.
