Amentum (United States)
Amentum is the U.S. government services company that spun off from AECOM in 2020.[i] It is part of the team managing and operating the Lawrence Livermore National Laboratory[ii] and has performed readiness assessments at the Los Alamos National Laboratory[iii], responsible for nuclear weapons design and maintenance.[iv] Amentum works “across all the key sites that enable the UK’s continuous-at-sea deterrent (CASD) program, including HMNB Clyde, home base for the Royal Navy’s operational submarines; HMNB Devonport, the largest naval base in Western Europe, BAE Systems Maritime in Barrow-in-Furness, where the Royal Navy’s submarines are built, at Rolls-Royce Nuclear in Derby, where submarine reactors are manufactured, and the Atomic Weapons Establishment in Berkshire, which is responsible for nuclear warhead design and manufacturing.”[v] Amentum also provides “essential through-life technical support” for nuclear reactors for UK submarines, including the nuclear armed Vanguard and Dreadnought class submarines.[vi] When launched as an independent company in 2020, Amentum became privately held, with the equity firms American Securities and Lindsay Goldberg as equal partners.[vii] However, in September 2024, Amentum completed a merger with Jacobs Solutions’ Critical Mission Solutions (CMS) and Cyber & Intelligence (C&I) Businesses, where the combined organization will be a publicly traded company.[viii] The merger also includes Jacobs’ former involvement in the Mission Support and Test Service (MSTS) consortium that manages and operates the U.S. Nevada National Security Site.[ix] However, as the findings of this report are based on financial data retrieved before September 2024, the effects of this merger are not taken into account for this report’s selection of fully profiled companies.
