What GigCapital7 does
GigCapital7 Corp. was the seventh Private-to-Public Equity (SPAC) vehicle incepted by GigCapital Global, sponsored by Dr. Avi Katz. On May 26, 2026, GigCapital7 completed its business combination with Hadron Energy, Inc., a Delaware corporation developing the Halo Micro-Modular Nuclear Reactor (MMR). The combined entity, renamed Hadron Energy, Inc., began trading on Nasdaq under the symbols HDRN and HDRNW, becoming the first publicly traded light-water micro-modular reactor company. The transaction delivered approximately $31 million in total equity funding (including $28 million retained from the GigCapital7 trust and $7.5 million in SAFE bridge financing), zero debt at closing, and approximately $24.5 million of post-closing cash.
Hadron's core product is the Halo MMR — a 10 MWe central-factory-manufactured, truck-transportable, light-water reactor engineered for continuous carbon-free baseload power with a 10-year refueling cycle. The company is pre-revenue and pursuing an NRC-licensed commercial pathway, anchored by the acceptance of its Quality Assurance Program Description Topical Report and a Principal Design Criteria whitepaper submission. Its target customer segments are AI data centers, industrial hubs, remote communities, critical infrastructure, and DoD/government installations, all of which require firm, on-site power independent of grid constraints. The intended revenue model combines direct reactor sales with long-term power purchase agreements, complemented by strategic deployment partnerships (Smartland Energy, Paragon Energy Solutions) and a domestic uranium fuel supply agreement with ConverDyn's Metropolis Works facility.

GigCapital7 partnerships and signals
Strategic signalPartnerships
Four partnerships are on record, tiered core and flagship.
- ConverDyncoreUranium Conversion Services Agreement securing domestic nuclear fuel supply for Halo micro-modular reactor. ConverDyn provides high-purity uranium hexafluoride (UF6) from its Metropolis Works facility in Illinois. This partnership establishes a critical domestic supply chain for reactor fuel, essential for U.S.-based deployment and regulatory compliance.
- Smartland EnergyflagshipNon-binding MoU establishing strategic collaboration to evaluate deployment of Halo Micro-Modular Reactor technology across up to five qualified Smartland projects initially, with Smartland targeting 12 projects totaling approximately 1.8 GWe by 2035. Smartland made initial strategic investment in Hadron. Partnership addresses growing demand from industrial and digital operators seeking firm, on-site power independent of grid constraints.
- Paragon Energy SolutionscoreNon-binding Memorandum of Understanding for design, development, and implementation of Instrumentation & Control (I&C) architecture for Halo Micro-Modular Reactor. Paragon develops I&C system architecture including safety and non-safety platform integration, control logic, human-machine interface, and cybersecurity, spanning First-of-a-Kind deployment with potential expansion to commercial units.
- U.S. Nuclear Regulatory Commission (NRC)coreRegulatory partnership for licensing pathway of Halo Micro-Modular Reactor. NRC accepted Hadron Energy's Quality Assurance Program Description Topical Report for formal review, marking the start of the NRC licensing process. Hadron submitted Principal Design Criteria whitepaper to NRC and engages actively with regulatory agencies.

GigCapital7 competitors and assessment
Company assessmentBroad incumbents
- Holtec International: Nuclear equipment manufacturer and reactor developer pursuing the SMR-160 small modular reactor and involved in nuclear fuel cycle and spent fuel storage. Comparable as an SMR developer with established nuclear industry relationships and broader nuclear fuel cycle involvement.
- Westinghouse Electric Company: Incumbent nuclear reactor OEM with the AP1000 large pressurized water reactor and an eVinci microreactor in development. Comparable as a competitor across the nuclear reactor spectrum, with significantly larger resources and existing utility relationships.
- BWX Technologies: Established nuclear components manufacturer and reactor services provider with strong Department of Defense and naval nuclear propulsion relationships. Comparable as a nuclear technology incumbent with microreactor ambitions and deep defense/government ties.
Regional players
- Rolls-Royce SMR: UK-based consortium developing a 470 MWe small modular pressurized water reactor with active UK government support. Comparable as an SMR developer pursuing factory-manufactured reactor designs, though primarily focused on the UK and European markets.
Direct peers
- NuScale Power: Publicly traded developer of small modular nuclear reactors (SMRs) for utility-scale deployments. Directly comparable as a publicly listed advanced nuclear reactor developer targeting commercial power generation, though at a larger scale (~77 MWe VOYGR) than Hadron's 10 MWe micro-modular design.
- Last Energy: Developer of small modular pressurized water reactors targeting European industrial and data center customers. Comparable as a microreactor/SMR developer pursuing distributed, behind-the-meter deployment with a factory-manufacturing approach similar to Hadron's.
- Oklo: Publicly traded developer of compact fast reactors and microreactors for commercial and defense markets. Most directly comparable to Hadron given the focus on small-scale, transportable microreactors with both data center and defense customer segments.
- X-energy: Developer of the Xe-100 high-temperature gas-cooled reactor and TRISO-X fuel for industrial and data center applications. Directly comparable as an advanced reactor developer with active data center commercial partnerships (e.g., Amazon) and Dow Chemical deployment agreements.
Emerging players
- Kairos Power: Advanced reactor developer pursuing fluoride salt-cooled high-temperature reactor (FHR) technology with active NRC engagement and Google power purchase agreement. Comparable as an advanced nuclear developer targeting data center demand with molten salt cooling technology.
- TerraPower: Bill Gates-backed advanced nuclear developer pursuing both a Natrium sodium-cooled fast reactor demonstration in Wyoming and traveling wave reactor technology. Comparable as an advanced reactor developer with hyperscaler and utility backing, though at larger scale than Hadron.
