US-based nuclear start-up Hadron Energy and GigCapital7 Corp (GIG), a Private-to-Public Equity company also known as special purpose acquisition company (SPAC) have entered into a definitive business combination agreement.
The proposed Business Combination contemplates that the existing security holders of Hadron will receive 100m shares of GIG stock, valuing the public Hadron prior to the raising of any public capital at approximately $1.2bn. At the close of the combination agreement Hadron will have access to approximately $200m in cash from the GIG trust account after the payment of transaction expenses. Hadron’s existing management team will continue to lead the combined company.
Hadron Energy is developing a micro-modular reactor (MMR) designed to deliver 10 MWe or 35 MWt using light water technology with a 10-year fuel cycle. It will be transportable in a shipping container, providing a versatile deployment model for end users such as AI data centres, remote communities, or an industrial hub.
“With power demand continuing to increase rapidly, nuclear energy is re-emerging as a compelling solution to today’s most pressing energy needs, with MMRs being central to this revolution,” said Hadron founder & CEO Samuel Gibson. “To tackle effectively the growing energy demand, we need to move beyond legacy nuclear technology.… With Hadron’s MMR technology, we are unlocking a new era of clean nuclear energy in a safe, scalable, and versatile way.”
In early 2025, Hadron submitted its Letter of Intent (LOI) to begin engaging with the US Nuclear Regulatory Commission (NRC) in pre-application activities. Shortly after, the company filed a Regulatory Engagement Plan and Quality Assurance Program Description with NRC. Hadron said it plans to submit Design Certification and Early Site Permit applications by the fourth quarter of 2026. Hadron claims to be at “the letter of intent stage with more than six potential customers”.
