Newcleo is a Paris-based nuclear firm building small reactors that run on recycled nuclear waste. In June 2026 it agreed to merge with Nasdaq-listed NewHold Investment Corp III, securing up to $429 million in cash — a SPAC route to public-market funding after raising $780 million privately since 2021 without yet turning a profit. Its technology both generates power and consumes existing nuclear-waste stockpiles.
