Hadron Energy, Inc. (NASDAQ: HDRN) completed its business combination with GigCapital7 Corp., receiving approximately $31 million in funding and beginning trading on the Nasdaq Stock Market under ticker "HDRN."

The transaction closed with $28 million remaining from the GigCapital7 trust account and an additional $2.8 million from previous SAFE bridge financings. After approximately $6.5 million in transaction expenses, the company will have about $24.5 million in cash with zero debt.

Hadron Energy develops the Halo Micro-Modular Nuclear Reactor, a 10 megawatt electric light-water reactor designed for factory manufacturing and transport by commercial vehicles. The reactor operates on a 10-year refueling cycle and targets industrial sites, data centers, and defense installations.

The company submitted its Principal Design Criteria whitepaper to the U.S. Nuclear Regulatory Commission on April 22, 2026, establishing the licensing framework for manufacturing and operating licenses. Hadron secured a domestic uranium services agreement with ConverDyn and announced partnerships with Paragon Energy Solutions and Smartland Energy.

The pro-forma equity valuation at closing reached approximately $766 million. GigCapital7 shareholders approved the transaction at an extraordinary general meeting on May 7, 2026.

"Now being a well-capitalized public company with no debt, we are executing with conviction on our development plan and NRC licensing pathway," said Sam Gibson, founder and chief executive officer of Hadron Energy.

The Halo reactor uses Low Enriched Uranium+ fuel, connecting to existing domestic light-water reactor fuel cycles rather than requiring High-Assay Low-Enriched Uranium supplies that constrain other advanced reactor developers.

Cohen & Company Capital Markets served as financial advisor to Hadron Energy, while Duane Morris LLP provided legal counsel. DLA Piper LLP served as legal advisor to GigCapital7.
