newcleo lists on Nasdaq via SPAC (NWCL)

2026-09-22

newcleo / NewHold III

Lead-cooled fast-reactor and MOX-fuel developer newcleo agreed to go public via NewHold Investment Corp III at a ~$2.4B pre-money value (up to $429M proceeds), targeting Nasdaq 'NWCL' in H2 2026. The deal closed on 21 Sep 2026 and shares began trading as NWCL on 22 Sep. Gross proceeds were $247M against up to $429M planned: an oversubscribed $216M PIPE, and only $31M from NewHold's trust — most SPAC holders redeemed rather than take shares. Former TVA chief executive Jeffrey Lyash chairs the board.
