About the company

Written by GovTribe AI ·

Amentum Services, Inc., doing business as AECOM, operates as a diversified federal prime contractor (97% of recent awards) and strategic subcontractor delivering engineering services, facilities operations, supply chain and logistics support, and mission-critical systems engineering across defense, civilian, and international customer bases on full-and-open vehicles with no set-aside designation. The parent entity, Amentum Government Services Holdings Sub LLC, a for-profit limited liability company based in Chantilly, Virginia, houses 16 named subsidiaries including DynCorp International LLC, Pacific Architects and Engineers LLC, PAE Aviation & Technical Services LLC, and Eg&G Defense Materials Inc., each contributing specialized capabilities spanning overseas contingency operations, aviation maintenance, defense article logistics, and classified undersea warfare systems.

Amentum's award footprint spans 4,166 contracts and sub-awards (4,058 prime, 108 sub) valued at $689.52 billion combined potential, with $47.71 billion obligated as of October 2026. Activity has accelerated sharply—976 awards in 2026 alone, compared to 153–207 annually in 2022–2025—driven by high-volume, low-dollar delivery orders against the GSA Federal Acquisition Service vehicle. The top five funding agencies by award count account for 53% of all awards: GSA Federal Acquisition Service leads with 911 awards worth $58.48 billion, followed by Department of the Navy Naval Sea Systems Command (715 awards, $26.66 billion), Department of the Air Force Space Command Space and Missile Systems Center (241 awards, $14.6 million), U.S. Coast Guard (168 awards, $11.25 billion), and Navy Information Warfare Systems Command (156 awards, $2.64 billion). When ranked by potential value, the Department of the Army Materiel Command Aberdeen Proving Ground anchors the portfolio with 51 awards worth $78.28 billion, and the Department of the Navy Naval Air Systems Command contributes 74 awards valued at $42.19 billion; these two customers alone represent higher-dollar strategic work alongside GSA's transactional supply orders.

Amentum's primary service delivery centers on engineering services (1,377 awards), warehousing and supply logistics (885 awards), and facilities support services (387 awards), with secondary concentrations in air transportation support and management consulting. A $200 million IDIQ from Army Corps of Engineers Far East for construction security monitoring in South Korea (awarded March 2026, completion March 2031) and a $235.4 million multiple-award IDIQ from Air Forces Europe and Africa for Kaiserslautern Installation Support Services (awarded December 2025, completion December 2035) exemplify large-scale base operations and security work. A $151.57 million Defense Information Systems Agency single-award contract (October 2025, completion September 2035) procures processor capacity services for IBM System Z mainframe environments; a $77.78 million GSA single-award indefinite-delivery vehicle (January 2026, completion January 2027) provides global supply logistics in Japan; and a $35.25 million Coast Guard single-award contract (September 2025, completion September 2030) delivers follow-on technical support to foreign military sales partners across vessel classes. The parent vehicle landscape concentrates heavily on the GSA FAS IDC 47QSCC26D0001 (884 task orders, $1.6 million combined potential) and GSA Multiple Award Schedule (236 task orders, $618.6 million), alongside Navy IDIQs for ship and marine systems, reflecting Amentum's dual posture as a high-volume supply distributor and a prime on specialized defense engineering vehicles.

Service Contract Inventory records spanning FY2022–FY2025 show SCI-reported invoiced revenue of $6.82 billion across 583 service contracts (473 prime, 110 sub-awards)—representing a subset of the vendor's federal and total enterprise activity. FY2025 invoiced $2.34 billion across 13,576 FTEs; FY2024 invoiced $1.75 billion across 11,771 FTEs; FY2023 invoiced $1.8 billion across 16,486 FTEs; and FY2022 invoiced $932.1 million across 8,231 FTEs. Government-paid hourly rates on prime SCI contracts range from a 10th percentile of $28.41/hr through a median of $75.35/hr to a 90th percentile of $180.88/hr, reflecting a broad labor mix spanning administrative, technical, and specialized engineering roles. Across SCI-reportable prime contracts, subcontractors represent an average 12% share of total contractor hours, with 513 named subcontractors deployed across the portfolio; this reflects a build-to-order delivery model where Amentum integrates specialized subs rather than relying solely on organic delivery. GSA Schedule offerings span 440 unique labor categories at rates from $30.22/hr (data entry, high school education) to $485.73/hr (subject matter expert, bachelor's degree, six years experience), with no security-cleared offerings, indicating GSA focus on administrative and technical labor for civilian agencies.

In the subcontractor role, Amentum delivers open-source intelligence services to Revacomm Inc. (contract awards May 2026 base $919,619 and March 2026 with six modifications totaling $1.3 million), missile sensor-aerial intelligence product director support to Tcom, L.P. for overseas operations (April 2026), C4 and IT system support to Innovative Management Concepts Inc. for Army Systems Integration (March 2026), undersea warfare combat systems platform and systems engineering for Virginia-class and Columbia-class submarines to Seacorp LLC (January 2026 dual awards), special operations forces emerging threats operations support to CACI NSS LLC (December 2025), and DARPA technical analytical support services (December 2025 awards). These subcontract engagements position Amentum as a specialized technical labor feeder to prime contractors anchoring defense and intelligence programs.

A recompete cliff of $9.46 billion (129 awards) reaches ultimate completion within the next twenty-four months, representing both renewal opportunity and execution risk across a portfolio where high-volume GSA FAS orders and strategic defense IDIQs interleave. The vendor competes predominantly full-and-open across all vehicles with no characteristic set-aside posture, positioning it as a mainstream federal contractor accessible to all federal customers at any tier of competition.
