Hadron Energy and GigCapital7 Corp. announced the completion of their previously announced business combination, marking the close of the SPAC merger process that will take Hadron Energy public.
The transaction received approval from GigCapital7 shareholders on May 7, 2026. Following the completion of the merger, the combined company has officially changed its name to Hadron Energy, Inc.
Beginning May 26, 2026, the company’s common stock and warrants are expected to begin trading on the Nasdaq under the ticker symbols “HDRN” and “HDRNW,” respectively. GigCapital7’s existing units will separate into their underlying components, consisting of one share of common stock and one warrant, and the units will no longer trade as a separate security under the previous “GIG” symbol.
Hadron Energy is focused on developing micro modular reactor technology through its Halo MMR platform. The company said the Halo MMR is designed to deliver 10 MWe of continuous power while being smaller, lower cost, and faster to deploy than many other proposed nuclear energy systems.
According to the company, the Halo MMR’s reactor vessel, core, and containment shell are fully truck-transportable, enabling deployment at AI data centers, industrial hubs, infrastructure facilities, remote communities, and other locations where traditional power solutions may be difficult to implement.
Hadron Energy said it is advancing the Halo MMR through technical development efforts, Nuclear Regulatory Commission licensing engagement, and strategic supply chain and deployment partnerships.
Cohen & Company Capital Markets served as financial advisor to Hadron Energy on the transaction. Duane Morris LLP acted as legal advisor to Hadron Energy, while DLA Piper LLP (US) served as legal advisor to GigCapital7.
