Newcleo develops advanced modular reactors and an integrated nuclear-fuel business covering reactor design, research and development, engineering, procurement and construction services, and MOX-fuel manufacturing. Its technology focus is Generation IV lead-cooled fast reactors using mixed-oxide fuel made from reprocessed nuclear materials, with the stated objective of closing the fuel cycle and reducing waste liabilities. On 10 August 2026, Newcleo and NewHold Investment Corp. III announced in an SEC-filed release that the SEC had declared effective Newcleo's Form F-4 registration statement for their proposed business combination and Nasdaq listing, subject to shareholder approval and customary closing conditions. Newcleo operates in 7 countries with over 900 employees and 31 patent families and generated approximately $80 million in revenue in 2024. Key projects include a joint venture with JAVYS for up to four LFR-AS-200 reactors in Slovakia, the PRECURSOR demonstrator in Italy, and a demonstration LFR-AS-30 reactor planned for Chinon, France by 2031. Its planned SPAC merger values the company at $2.4 billion pre-money, with listing expected in the second half of 2026.
