Executive Summary
A $14.9B mega-contract batch dominated by a $10.6B DOE Hanford tank farm management award to Amentum subsidiary signals sustained federal commitment to environmental remediation through 2025. HHS cluster ($1.4B across eligibility support, pathogen tech, and NCI R&D) bolsters Leidos, Serco, and Cerus with revenue through 2026-2028. DHS/GSA awards ($1.8B in shipbuilding, construction, IT, and engineering) provide long-term visibility to Eastern Shipbuilding, AECOM JV, Leidos, Booz Allen, and CACI amid infrastructure and defense priorities.
