Fairfax County Lands Headquarters of Leading Government Contractor Amentum Services, Inc.

 

Fairfax County, Virginia (February 27, 2023) – Earlier this morning, Governor Glenn Youngkin announced that Amentum Services, Inc., a leading provider of engineering and advanced solutions and services to the U.S. government, allies, and commercial companies, will invest $495,000 to relocate its headquarters from Germantown, Maryland to Fairfax County. In 2022, the company acquired PAE Incorporated, another leading government services contractor, and will consolidate its integrated operation at Amentum’s office at 4800 Westfields Boulevard in Chantilly, creating 157 new jobs. 

“The relocation of our company headquarters to Chantilly, Virginia, grants more convenient access not only for our local employees, customers and partners, but also for everyone in our extended team who are doing business in the Washington, D.C. area,” said John Heller, Amentum CEO. “We look forward to strengthening our connections with and expanding our business in the Northern Virginia area and establishing our new headquarters as the ideal centralized location for our global organization.” 

“We are honored to welcome Amentum to Fairfax County and want to thank them for choosing Chantilly for their new headquarters,” said Victor Hoskins, president and CEO of Fairfax County Economic Development Authority (FCEDA). “Our world-class network of mission-driven companies just grew even stronger, and together our business community will continue to innovate here and affect change globally.” 

Amentum is a leader in global engineering, project management, and solutions integration, trusted to modernize the most critical missions anywhere in the world. Driven to create a safer, smarter, cleaner world, Amentum innovates as a team of inventive doers passionate about making a difference. Underpinned by a strong culture of ethics, safety, and inclusivity, Amentum is fiercely committed to operational excellence and successful execution. The company has more than 44,000 employees in 85 countries on all seven continents, including locations across Virginia.

“I want to thank and congratulate Amentum for choosing Fairfax County as its home base,” said Fairfax County Board of Supervisors Chairman Jeffrey C. McKay. “Our long-term investment into making Fairfax County the top choice to locate a global business is bearing fruit, and I am thrilled that Amentum has chosen to take advantage of what we offer.”

Fairfax County Economic Development Authority worked with the Virginia Economic Development Partnership to secure the project for Fairfax County and Virginia.

“Fairfax County offers the location, access to decision-makers, and talent pipeline that global providers like Amentum are seeking, and we are proud to welcome the company’s leadership and operations team to Virginia,” said Governor Glenn Youngkin. “Amentum joins the ranks of the Commonwealth’s diversified ecosystem of more than 800 corporate headquarters across a broad cross-section of industries.”
