Overview
Leidos Holdings is a US government technology contractor. For the fiscal year ended 2 January 2026 it reported revenues of US$17.17 billion[10]. The company traces its origins to 1969, when physicist Robert Beyster founded it[10]. Its 10-K states that it employed approximately 47,000 full- and part-time staff, of whom about 41,900 were in the United States and the rest in about 45 other countries[10]. Leidos is headquartered in Reston, Virginia. Most of its revenue comes from US defence, intelligence, civil-agency and health customers. That customer base sets it apart from the commercial outsourcers higher in this ranking, but its IT modernisation, enterprise IT operations and systems-engineering contracts are among the largest outsourcing awards in the US federal market.
