HGP Intelligent Energy plans to merge with Nasdaq-listed Meshflow Acquisition Corp. in a transaction implying a pro forma equity value of about $1.2 billion and expected gross proceeds of roughly $345 million. The deal values HGP at $800 million before the merger, while the $1.2 billion figure assumes no redemptions by Meshflow shareholders. The combined company would operate under Leyte Parent, Inc. HGP plans to use the proceeds to commercialize its CoreHeld initiative, which would retrofit decommissioned naval reactors into 450- to 520-megawatt commercial power plants. Its technology includes variable-speed reactor coolant pumps for real-time load-following and NthSim, a digital-twin platform for continuous reactor modeling. HGP operates the Integrated Naval Nuclear Energy Campus and has partnerships and federal backing tied to nuclear innovation, including work with The Shaw Group and selection for the Department of Energy’s Nuclear AI Moonshot program in July 2026. Earlier materials identified the federal initiative as the Prometheus program, creating a discrepancy in the program’s reported name.
