HGP Intelligent Energy to go public in $1.2 billion SPAC deal with Meshflow

HGP Intelligent Energy will become a publicly traded company through a combination with Meshflow Acquisition Corp., valuing the nuclear load-following technology developer at a pre-money $800 million. The deal could bring about $345 million in gross proceeds to help fund product qualification, digital twin development and a planned nuclear campus for data center power.

Why it matters: - HGP is trying to commercialize nuclear load-following technology for power-hungry data centers and other variable loads. - The deal gives HGP access to public markets and new capital for pump manufacturing, software validation and site development. - The company’s pitch centers on helping reactors track real-time grid demand while staying inside safety limits.

What happened: - HGP Intelligent Energy and Meshflow Acquisition Corp. signed a definitive business combination agreement on Sept. 8, 2026. - The transaction will create Leyte Parent, Inc., which will serve as the public company. - HGP expects to go public through the SPAC combination with Nasdaq-listed Meshflow. - All existing HGP equity holders will roll 100% of their holdings into the combined company. - HGP management, principal equity holders and Meshflow’s sponsor have agreed to a customary post-closing lockup.

The details: - HGP’s control layer combines NthSim digital twin software with variable-speed reactor coolant pump hardware. - The system is designed to adjust coolant flow instead of moving control rods. - HGP says the software recalculates the fastest safe power change about 10 times per second. - The technology is designed to help reactors follow minute-to-minute swings in demand, including AI data center loads, while operating within safety limits. - HGP says most reactors operating today or announced today cannot follow load while islanded from the grid. - The control layer is designed for the existing pressurized water reactor fleet and announced small modular and advanced designs. - The technology can be deployed as new-build hardware, a retrofit package or a factory-integrated module. - HGP says the global installed base includes more than 600 reactors operating or under construction. - HGP’s patent-pending portfolio covers variable-speed reactor coolant pump architecture, thermal margin and pump-speed control, digital twin monitoring and predictive control, and related pump hydraulics. - The portfolio spans large pressurized water reactors, small modular reactors, microreactors and sodium fast reactors. - In July 2026, HGP was selected as a consortium partner on Prometheus, the AI-for-nuclear effort under the Department of Energy’s Genesis Mission. - Idaho National Laboratory leads the consortium, with Argonne, Oak Ridge and Sandia national laboratories and other commercial partners. - The U.S. government has contributed $60 million to the consortium against more than $200 million of industry cost-share. - HGP is separately developing the Integrated Naval Nuclear Energy Campus for federal sites to serve islanded and grid-connected data center load under long-term power agreements. - HGP is headquartered in Dallas, Texas. - Founder and CEO Gregory Forero previously owned and operated HGP Storage, developed a first-of-a-kind battery energy storage project in ERCOT and served as a vice president at Constellation. - Forero has managed more than 22 gigawatts of generation assets during his career. - Jeffrey Frase has joined HGP’s board. - Frase led global oil trading at Lehman Brothers and JPMorgan, spent 17 years at Goldman Sachs in commodities and served as co-CEO of Noble Group. - Meshflow is a Cayman Islands exempted blank-check company formed to pursue a merger or similar business combination. - Meshflow raised $345 million in its December 2025 IPO, led by Cantor Fitzgerald. - Meshflow’s units, Class A ordinary shares and warrants trade on Nasdaq as MESHU, MESH and MESHW. - Cantor Fitzgerald is HGP’s exclusive financial advisor. - DLA Piper is legal advisor to Cantor. - Pillsbury Winthrop Shaw Pittman is legal advisor to HGP. - Ashurst Perkins Coie US LLP is legal advisor to Meshflow. - More information is available at HGP’s website and Meshflow’s website.

Between the lines: - The transaction values HGP at a pre-money equity value of $800 million. - The deal implies a pro forma enterprise value of about $921 million and a pro forma equity value of about $1.2 billion, assuming no redemptions. - The combination is expected to provide about $345 million of gross proceeds, including cash in Meshflow’s trust account before redemptions. - The capital raise is aimed at turning HGP’s reactor-control concepts into qualified hardware and validated software, which is usually a long and expensive path in nuclear power. - HGP is positioning nuclear as a dispatchable partner for AI infrastructure, a market where around-the-clock power demand is rising. - The deal also signals investor appetite for nuclear technologies tied to data-center power and federal energy programs.

What’s next: - Leyte Parent, Inc. intends to file a registration statement on Form S-4 with the SEC. - After the SEC declares the filing effective, Meshflow will send a definitive proxy statement and prospectus to shareholders. - Meshflow shareholders will vote at an extraordinary general meeting on the transaction. - Proceeds are expected to fund qualification and manufacturing of the variable-speed reactor coolant pump, continued digital twin development, site development and licensing work for the campus, working capital and transaction expenses. - The transaction still faces regulatory approvals, shareholder approval, redemptions and other closing conditions. - HGP and Meshflow both caution that the deal may not close on the expected terms or timeline.

The bottom line: - HGP is using a SPAC merger to fund a bid to make nuclear reactors more flexible, more data-center-friendly and commercially ready.
