Amentum Holdings saw its stock jump 3.1% in pre-open trading after the company disclosed it had been chosen to provide long-term maintenance and engineering support at NASA’s Langley Research Center in Hampton, Virginia. The Center Maintenance, Operations, and Engineering II - CMOE II - contract is valued at approximately $974 million and runs for around a decade.
Under the CMOE II award, Amentum will be responsible for maintaining and operating advanced research infrastructure at Langley, including wind tunnels, laboratories and the utilities that support them. The scope also includes engineering services such as design, construction oversight, project management and the recertification of pressure systems.
Investors reacted to the standalone press release announcing the NASA win, which arrives on top of several recent contract announcements that have expanded Amentum’s backlog. Those prior awards include a previously disclosed COSMOS flight mission operations contract of roughly $500 million and more than $1 billion in classified defense engineering and logistics contracts. The company reported all of these awards as part of its Q3 2026 results earlier this month.
The CMOE II news appears to have sharpened investor focus on Amentum’s contract momentum, particularly given the firm’s stated $32 billion pipeline of pending awards. Company disclosures indicate that about two-thirds of that pipeline represents new business opportunities, a point market participants appear to be weighing as evidence of potential durable federal revenue.
Market context did not contribute positively to the move. The S&P 500, Dow Jones and NASDAQ were all modestly lower ahead of the open, which suggests the company-specific disclosure is the primary catalyst for AMTM’s pre-market strength rather than any broader sector or macro forces.
Despite the uptick, Amentum shares remain well below their 52-week high of $38.11 and are trading near the lower end of the annual range. That valuation backdrop may be intensifying the market’s response to a tangible, large-scale contract award, as investors interpret the deal as a multi-year revenue underwrite tied to federal spending.
In sum, the CMOE II award adds a near-billion-dollar, decade-long contract to Amentum’s backlog, reinforcing previously announced wins and highlighting a sizable pipeline of pending federal work. The disclosure has driven pre-market buying in a session otherwise weighed down by modest declines across major U.S. equity indexes.
