Leidos reports financial performance by operating segment rather than by individual named product; its disclosures do not provide revenue percentages for specific products [25]. [12]

For the six months ended July 3, 2026, the corresponding split was $8.170 billion U.S. and $761 million international, approximately 91.5% and 8.5%.

Company history

J. Robert Beyster founded Leidos’s predecessor, Science Applications International, in 1969. In 2013, the company separated its technical-services and enterprise IT-services businesses into a new, separately traded Science Applications International Corporation; the remaining business adopted the Leidos name.[38][39]

Leidos expanded significantly in 2016 by combining with Lockheed Martin’s Information Systems & Global Solutions business.[40] It acquired engineering company Dynetics in 2020, followed in 2021 by managed IT provider 1901 Group and naval architecture firm Gibbs & Cox.[41] In 2022, it acquired Cobham Special Mission, adding Australian airborne surveillance and search-and-rescue services.[45] Thomas A. Bell became CEO in 2023, succeeding Roger Krone.[46] [39]
