Amentum-Jacobs merger to close Friday

The mega-merger of Amentum Services, Chantilly, and the government and cyber businesses of Jacobs Solutions, Dallas, was scheduled to close Friday, after deadline for Weapons Complex Monitor.

The was to be finalized by 4:10 p.m. Eastern time on Friday, according to Jacobs’ press release, creating a new, publicly traded government and defense behemoth that would loom large over Department of Energy nuclear-weapon sites, where both companies already do a lot of business.

Monday, Sept. 23, was “the record date for the spin-off distribution of its Critical Mission Solutions and Cyber & Intelligence government services businesses” to Amentum, according to a Jacobs release issued earlier this month.

The combined company will be called Amentum Holdings. Its shares will begin trading on the New York Stock Exchange under the ticker “AMTM” on Monday, according to a July regulatory filing. Amentum CEO John Heller, 61, was to lead the new company.

Also this week, Amentum Holdings formally announced the members of its board of directors, which will be chaired by former Jacobs chief executive officer Steven Demetriou. Heller will also be on the board.

Both the legacy Amentum and Jacobs are lead contractors on billions of dollars’ worth of business within the Department of Energy’s nuclear weapons complex.

In 2017, Jacobs purchased CH2M Hill, a rival engineering and construction contractor.

Some of the prominent companies that are part of Amentum’s history include EG&G, Morrison-Knudsen, Westinghouse Government Services, URS, Lear Siegler Services, DynCorp and Pacific Architects and Engineers.
