GigCapital Global Enhances Its Private-to-Public Equity Platforms to Elevate High-Tech Firms From Private to Public Markets

Audio By Carbonatix

PALO ALTO, Calif.--(BUSINESS WIRE)--Dec 8, 2025--

GigCapital Global, along with its affiliate GigCapital7 Corp. (Nasdaq: GIG), proudly supports Hadron Energy Inc. (“Hadron Energy”) as its Quality Assurance Program Description Topical Report has been accepted for review by the United States Nuclear Regulatory Commission (“NRC”). This milestone reflects the start for formal NRC review of Hadron Energy’s Halo Micro Modular Reactor, validating that Hadron Energy’s submission includes the necessary information for a detailed technical evaluation by the NRC, underscoring the company's robust early licensing efforts.

“Hadron Energy exemplifies the type of company with which GigCapital Global aspires to partner in deploying our Private-to-Public Equity (PPE) TM business approach, exhibiting disciplined innovation that our nation needs,” said Dr. Avi Katz, Founding Managing Partner of GigCapital Global and CEO of GigCapital7. “The NRC’s acceptance for review highlights Hadron Energy’s strong engineering culture and readiness to transition to a public company. We are proud to support and advance Hadron Energy’s micro modular nuclear reactor (MMR) technology, which promises to reinforce U.S. energy independence and economic growth.”

Dr. Katz and the GigCapital Global team launched their first Private-to-Public Equity (PPE) platform in 2017, applying the well-established Special Purpose Acquisition Company, or SPAC, model, to create a disciplined and reliable fast path to public capitalization for emerging technology leaders. This structure gives transformational companies access to public market versatile funding vehicles while preserving the operational focus and strategic flexibility they need during the transition from private to public markets.

GigCapital Global concentrates on advanced industrial sectors that measurably improve quality of life and align with U.S. national priorities, ensuring that the companies GigCapital Global supports have both long-term relevance and strong growth potential.

A defining element of GigCapital Global’s approach is its Mentor-Investor™ model. Rather than acting as a passive financial sponsor, the team works side by side with partner companies, sharing operational responsibilities and supporting strategic execution before, through, and after the business combination that takes the company public. This active involvement strengthens the leadership teams, accelerates scale, and helps ensure durable long-term performance in the public markets.

Building on the previous many years of strong results delivered to investors and partner companies, GigCapital Global continues to launch new Private-to-Public Equity (PPE) platforms designed to support the capitalization and long term growth of businesses aligned with U.S. national priorities. These platforms open the door for a broad range of public market investors to participate in the growth of high impact companies, while giving those companies a structured and reliable path to scale.

Recently, GigCapital8 Corp. completed its IPO and is in the process of searching for an initial business combination, and its ninth Private-to-Public (PPE) entity, GigCapital9 Corp. has earlier this week filed its Form S-1 Registration Statement for its initial public offering.
