Insights

Financial Analyst

Amentum (NYSE: AMTM) has secured a strategic win as the sole program and project management delivery partner for the UK's Sizewell C nuclear power station, marking a significant expansion of the company's nuclear energy portfolio. This long-term contract, extending until the station becomes operational, positions Amentum at the forefront of the growing global nuclear renaissance.

The comprehensive scope includes program management, project controls, engineering services, and site management solutions—creating hundreds of new jobs for Amentum in the UK. The project's scale is substantial, with two 1.6 gigawatt EPR reactors that will eventually power six million homes while eliminating approximately 9 million metric tons of carbon emissions annually.

The UK government has demonstrated strong commitment to the project, maintaining 76% ownership of Sizewell C and pledging $3.2 billion in investment. This government backing significantly reduces project cancellation risk and underscores the strategic importance of nuclear power for UK energy security amid volatile global gas markets.

A key advantage for Amentum is their ability to leverage experience from Hinkley Point C to deliver cost efficiencies through design replication. This knowledge transfer represents a competitive advantage in project execution and potentially stronger margins through operational efficiencies.

While the contract value remains undisclosed—a notable limitation for financial impact assessment—the project's scale, long-term nature, and government backing indicate material positive revenue impact for Amentum over an extended timeframe. The contract aligns perfectly with global energy transition trends favoring reliable, low-carbon baseload power sources.

CHANTILLY, Va.--(BUSINESS WIRE)-- Amentum (NYSE: AMTM) has been selected as sole program and project management delivery partner for Sizewell C, a new nuclear power station that will strengthen the United Kingdom’s energy security.

“Sizewell C’s always-on nuclear electricity will boost UK energy security at a time of volatile global gas prices, leading to lower and more predictable energy costs,” said Andy White, Senior Vice President of Amentum Energy & Environment International. “Our international program management experience and the learning from our work at Hinkley Point C will help to advance a project which is crucial for job creation and economic growth across the country.”

Nigel Cann, Joint Managing Director of Sizewell C, said: “Amentum’s global program management capabilities and international nuclear new build experience will help us deliver the game-changing benefits and cost savings of replicating Hinkley Point C’s reactor design, while supporting our commitment to creating jobs and skills in the UK and maintaining the national capability essential for the nuclear renaissance.”
