Amentum (NYSE:AMTM) shares climbed 3.1% in premarket trading on Thursday after the engineering and technology services company was awarded a $974 million contract by NASA to support operations at the Langley Research Center in Hampton, Virginia.

The Center Maintenance, Operations, and Engineering II contract, known as CMOE II, covers a broad range of maintenance, engineering and infrastructure services supporting NASA’s research activities at the facility.

Amentum to support NASA Langley research infrastructure

Under the contract, Amentum will maintain and support critical research systems including wind tunnels, laboratories and associated research utilities.

Its responsibilities will extend to preventive maintenance, repairs and central utility operations across both institutional buildings and specialised research facilities at NASA Langley.

The company will also provide engineering capabilities spanning design, project management, construction management and the recertification of pressure systems.

Contract includes laboratory and wind tunnel modernisation

Amentum will play a role in modernising infrastructure across the research centre, including projects designed to automate laboratory systems and enhance wind tunnel testing facilities.

The scope requires the company to manage complex technical systems and operational processes while overseeing capital improvements intended to maintain and upgrade Langley’s research capabilities.

The contract strengthens Amentum’s exposure to long-term U.S. government and space-sector programmes while adding a sizeable award to its existing NASA work.

NASA relationship extends beyond six decades

Amentum has supported NASA programmes for more than 60 years, giving the company extensive experience managing specialised infrastructure and engineering requirements across the agency’s facilities.

The latest $974 million award extends that longstanding relationship and positions Amentum to support the maintenance, operation and modernisation of one of NASA’s major research centres.

Investor reaction was positive following the announcement, with the scale of the contract and continuation of Amentum’s established NASA partnership helping lift the shares in premarket trading.
