Hadron Energy said it has completed its business combination with special-purpose acquisition company GigCapital7 and will begin trading on the Nasdaq under the ticker HDRN on May 26, 2026.
The deal formally closed on May 22, 2026 after GigCapital7 shareholders approved the merger earlier in May and after the SEC declared the combined Form S-4 registration effective.
Hadron is promoting a 10 megawatt-electric micro-modular reactor called the Halo, which the company describes as a transportable, truck-deliverable light-water design intended for shorter deployment timelines than conventional power plants.
Company materials emphasize that Halo’s engineering blends proven pressurized-water reactor safety features with modular factory construction to cut the time to bring a unit online from years to months in some cases.
Ahead of closing, Hadron and sponsors aligned on a pro-forma equity valuation around $600 million and completed pre-IPO financings to preserve runway for licensing and supplier development.
The company is pitching Halo directly at cloud operators and AI labs as a predictable, behind-the-meter power option for GPU-heavy clusters that are sensitive to interruptions and price volatility.
Hadron’s move comes as data-center developers increasingly consider on-site generation, microgrids, and other behind-the-meter resources to sidestep long grid interconnection timelines and capacity bottlenecks.
Market research and reporting show many planned data-center projects are adding dedicated on-site generation — often natural gas today — while interest in small modular reactors and other firm, low-carbon sources has grown as AI workloads swell.
That context helps explain why Hadron frames Halo as not only a low-carbon alternative but also as an asset that can be sited near campuses and scaled as compute demand grows, subject to licensing and local approvals.
Regulatory and supply-chain milestones remain material hurdles; Hadron’s public filings and press releases flag ongoing licensing efforts, supplier partnerships, and further engineering tests before commercial deployments.
For hyperscalers and data-center landlords, the trade-offs are practical and financial: faster access to firm power can protect model-training schedules and operating margins, but behind-the-meter builds also carry capital, permitting, and community-impact costs.
Hadron’s Nasdaq debut makes it one of the first publicly traded companies focused on light-water micro-modular reactors and will put its technical claims under greater investor and customer scrutiny as the industry evaluates whether truck-transportable nuclear units can meet real-world timelines for AI-scale power.
