Job description

newcleo is an innovative nuclear energy company developing AMRs cooled by liquid lead, and nuclear fuel from recycled nuclear waste, with the goal of delivering abundant, competitive, low-carbon energy.

The Company was founded by physicist-entrepreneur Stefano Buono following the USD 3.9 billion sale of his previous venture – Nasdaq-listed nuclear medicine company Advanced Accelerator Applications – to Novartis.

With over $80 million in revenue, other income, and financial income in 2024 including from its operating companies, approximately $780 million in private funding, and more than 900 highly skilled employees across Europe and the United States, the Company has built a network of over 100 industry partnerships and supports its growth through the targeted acquisition and vertical integration of key companies in the nuclear supply chain.

On May 27, 2026, newcleo announced that it had entered into a definitive agreement for a business combination with NewHold Investment Corp. III (NASDAQ: NHIC) in a transaction that, upon closing, would result in newcleo becoming a U.S.-listed public company. The combined company is expected to be listed on the Nasdaq exchange under the ticker symbol “NWCL” following an anticipated transaction close in the second half of 2026, subject to satisfaction of customary closing conditions.
