About the company

Amentum Environment & Energy, Inc. N&E Division, a wholly owned subsidiary of Amentum Nuclear & Environment Holdings, Inc., delivers environmental remediation, site decommissioning, groundwater treatment, and infrastructure support services to federal agencies as a prime contractor (98% of awards) on full-and-open contracts without reliance on SBA set-asides. The company is headquartered in Aiken, South Carolina and competes across NAICS remediation services (567000) and environmental consulting (541620) with a federal award footprint valued at $1.05 billion across 428 recent awards.

The N&E Division's customer concentration centers on transportation and defense agencies. The Department of Transportation Federal Aviation Administration accounts for the largest single customer relationship: 70 awards with $366.5 million combined potential value across Headquarters and the Technical Center in Atlantic City, New Jersey. The Department of the Navy (85 awards), Department of the Army (66 awards), and the National Aeronautics and Space Administration (39 awards) round out the top tier, together representing 67% of recent awards. The FAA Technical Center alone anchors $186.2 million, more than half of the top-five customers' combined value, reflecting Amentum's dominant role on the Environmental Remediation Support Services (ERSS) single-award indefinite delivery contract valued at $101.8 million through June 30, 2031.

The ERSS contract is Amentum's flagship vehicle. Under this FAA IDC, the company has issued more than 50 delivery orders since 2021 for groundwater treatment plant operations and maintenance, site decommissioning, non-time critical removal actions, geospatial services (GIS/GPS), National Environmental Data Repository Management, and environmental investigations at the William J. Hughes Technical Center Superfund site in Atlantic City. Recent ERSS delivery orders include a $15.2 million non-time critical removal action for the AVGAS fuel farm (Area 41) and underground storage tank source area (awarded July 16, 2026, due December 28, 2027), a $4.4 million landfill waste removal project (Area 56, awarded July 29, 2026), a $2.1 million groundwater treatment at Area Y (awarded September 10, 2026), and a $5.2 million in situ remedial enhancements project using PlumeStop technology for volatile organic compound hot spot treatment at Area 20A (awarded May 2022, due May 31, 2024). The firm employs firm-fixed-price, time-and-materials, and cost-no-fee pricing models across different task order scopes.

Beyond the FAA, Amentum holds significant indefinite delivery vehicles across the Department of Defense. Indefinite Delivery Contract N6274298D2106 (82 task orders) and IDC 692M1521D00005 (65 task orders, $78.5 million combined potential value) anchor Navy and Army work respectively. IDC DACA5694D0021 (34 task orders) supports Army Corps of Engineers projects, while IDC W9127N12D0004 (22 task orders, $5.5 million) funds Air Force installation and environmental work. The company also delivers sub-contract services on Department of Energy national laboratory management and operations programs, including work under Hanford Laboratory Management and Integration LLC (awarded February 2024 and July 2024 for 222-S Laboratory operations and maintenance, facility seismic re-evaluation, and vacuum system design) and Fluor Marine Propulsion, LLC (awarded March 2026 for Naval Nuclear Laboratory facility structural re-evaluation and design work).

Activity has remained consistent at 12–16 awards per year over the past five years, with 16 awards in 2026 (as of September 10). The vendor faces $29.6 million in recompete exposure within the next twenty-four months across 11 awards. Service Contract Inventory data shows minimal SCI-reported invoiced revenue across FY2022–FY2025 (zero dollars), reflecting that Amentum's federal services contracts either fall below the $150,000 SCI reporting threshold or are structured as fixed-price delivery orders rather than time-and-materials labor-hour contracts. SCI records show only 5.5 FTEs reported in FY2025 and 17.6 FTEs in FY2024, a partial and incomplete snapshot of the company's federal workforce scale. The vendor does not report sub-engagement across its prime contracts in the SCI dataset.

Amentum Environment & Energy operates as part of a larger corporate family that includes 28 named subsidiaries spanning nuclear waste management (Nuclear Waste Partnership LLC, USA Repository Services LLC, West Valley Environmental Services LLC), government environmental services (Washington Government Environmental Services Company LLC, Washington Savannah River Company LLC), infrastructure operations (Washington River Protection Solutions LLC, United Cleanup Oak Ridge LLC), and engineering consulting (AECOM International Projects, Inc., URS Energy & Construction, Inc.). The N&E Division's remediation and infrastructure focus sits within the Environmental & Energy sector of the broader Amentum Holdings parent structure, positioning it as a prime vehicle for federal environmental cleanup, site operations, and technical support work at civilian and defense installations nationwide.
