Amentum Holdings Inc (NYSE:AMTM) shares rose in Wednesday's session after the company secured a $406 million contract tied to the UK's first small modular reactor (SMR) program.

Contract scope and timeline

Great British Energy–Nuclear (GBE-N) has awarded a $406 million (300 million pounds) contract to a joint venture between Amentum and Cavendish Nuclear as owner's engineer for the UK's small modular reactor (SMR) program.

The agreement, with a maximum term of 14 years, will support the deployment of Rolls-Royce SMR technology at the Wylfa site in North Wales, advancing plans for the UK's first SMR project.

Project role and execution

The Amentum-led joint venture, Litmus Nuclear, will provide independent technical assurance across design, safety, engineering, construction, and commissioning.

The support will help Great British Energy–Nuclear advance critical aspects of the SMR program. It will also assist GBE-N in reaching a final investment decision and meeting regulatory requirements.

Wylfa was selected in November 2025 as the site for the UK's first SMRs, with 470MWe reactors designed for faster construction than traditional plants.

Leadership commentary and company context

"This award recognizes Amentum’s expertise to accelerate the global expansion and revitalization of nuclear energy… Amentum will draw upon our expertise in nuclear science and engineering to provide independent technical and delivery assurance, helping GBE-N advance the SMR program and bolster the UK’s energy security and industrial base," said Loren Jones, senior vice president and head of Amentum’s Energy & Environment-International business.

Amentum provides advanced engineering and technology solutions focused on science, security, and sustainability.

Technical Analysis

The stock is currently trading 5.9% below its 20-day simple moving average (SMA) and 15.9% below its 50-day SMA, indicating some short-term weakness.

Over the past 12 months, shares have increased by 45.94% and are currently closer to their 52-week highs than their lows, reflecting strong longer-term performance.

The RSI is at 34.10, which is considered neutral territory, suggesting that the stock is neither overbought nor oversold. Meanwhile, MACD is at -1.3636, below its signal line at -1.3176, indicating bearish pressure on the stock.

The combination of a neutral RSI and a bearish MACD suggests mixed momentum, indicating that while the stock has shown strength over the past year, current technical indicators warrant caution.
