newcleo Completes Acquisition of Bonifait Pesage, Bringing Nuclear-Grade Scales In-House

LONDON and PARIS, Nov. 02, 2026 (GLOBE NEWSWIRE) — newcleo plc (“newcleo” or the “Company”) (Nasdaq: NWCL), a pioneer in advanced modular reactor (“AMR”) technology and nuclear fuel manufacturing, today announced that it has completed its previously announced acquisition of Bonifait Pesage, a French maker of nuclear-grade scales and precision weighing equipment that serves high profile customers across the French nuclear sector.

The deal extends the vertical integration approach newcleo has pursued since 2023, when it acquired Fucina, SRS and Rütschi. The acquisition of Bonifait Pesage brings another specialist supplier under the newcleo umbrella ahead of development of the Company’s planned mixed-oxide (MOX) fuel manufacturing facilities in the United States and Europe, where nuclear-grade weighing equipment will support the tracking and control of nuclear materials. Through the acquisition of Bonifait Pesage, newcleo gains preferred access to specialized precision weighing equipment, lowers its supply-chain exposure and can tailor equipment to its own requirements.

“Bonifait Pesage adds a further building block to the vertically integrated supply chain we have assembled to produce MOX fuel for our lead-cooled fast reactors,” said Stefano Buono, CEO and Co-Founder of newcleo. “Having their expertise and technologies inside newcleo will allow us to build our MOX fuel facilities on a supply chain we know and can rely on. We welcome the Bonifait Pesage team and will continue supporting their growth as a supplier to the wider nuclear industry.”

“Our team now joins a group that is building across the nuclear fuel cycle,” said Laurent Bonifait, Founder of Bonifait Pesage. “Operating as part of the newcleo team gives us a platform to grow leveraging the global growth of the nuclear industry, while we continue to serve the historical customers who rely on us.”

Bonifait Pesage, founded in 1954 and based in southern France, manufactures, installs, calibrates and services weighing equipment and provides technical support. Since 2017 it has been certified to maintain and verify weighing systems in ionizing-radiation environments, and its specialist staff are qualified to work in areas where radiation exposure may occur. The company reported revenue of approximately €2.1 million in 2025. The transaction valued Bonifait Pesage at an equity value of €1.8 million, with purchase consideration comprising a combination of cash and newcleo shares.
