CHARLOTTE, N.C. and STAMFORD, Conn., March 26, 2025 (GLOBE NEWSWIRE) — Terrestrial Energy Inc., a developer of small modular nuclear power plants using advanced reactor technology, and HCM II Acquisition Corp. (Nasdaq: HOND), today announced an agreement for a business combination (the “Transaction” or the “Business Combination”) that will result in Terrestrial Energy becoming a public company to be listed on Nasdaq under the ticker symbol “IMSR”.
Company
Background
Terrestrial Energy is a developer of Generation IV nuclear plants using proprietary Integral Molten Salt Reactor (IMSR) technology. IMSR technology captures the transformative operating benefits of molten salt reactor technology in a small modular plant design that represents true innovation in affordability, efficiency, and versatility of nuclear energy supply.
Terrestrial Energy’s IMSR plants will supply zero-carbon, clean, firm, low-cost, high-temperature industrial heat and/or electricity for a dual-use energy role. Industrial applications include data center power supply, industrial heat and power, grid power, and green fuels sectors. The company’s IMSR plant design, consisting of two operating IMSRs, has an 822 MWth / 390 MWe capacity. Terrestrial Energy’s IMSR technology is differentiated from legacy nuclear technology through its use of molten salt reactor technology, which offers high efficiency and inherently safe operation.
Terrestrial Energy’s IMSR plants are designed to make pragmatic use of low-cost, readily available Standard-Assay Low Enriched Uranium (LEU enriched to under 5% U235) fuel, enabling secure and scalable fuel supply chains necessary for widespread fleet deployment. Terrestrial Energy believes the use of LEU fuel is a key advantage given significant challenges to the commercial supply of High-Assay Low- Enriched Uranium (HALEU is enriched to between 15% and 20% U235) due to geopolitical tensions.
In February 2025, Terrestrial Energy announced the IMSR plant’s selection by Texas A&M University in a competitive RFP process to site a commercial IMSR plant at the Texas A&M-RELLIS campus. The partnership will provide a platform for Terrestrial Energy to showcase a commercial IMSR plant with a project that benefits from the Texas A&M University System’s national leadership in nuclear technology research and development.
Led by CEO Simon Irish and a highly experienced management team, Terrestrial Energy is supported by a top-tier board of directors consisting of former C-Suite executives of leading U.S. nuclear utilities and engineering firms. The company is also supported by an expert advisory board, which includes former U.S. Secretary of Energy Ernest Moniz serving as senior counsel to the advisory board, as well as former Prime Minister of Canada, Stephen Harper, and former BP p.l.c. President and CEO, Lord John Browne, along with other highly experienced professionals from energy, industrials, aerospace and defense, finance and government. The HCM II Board of Directors also features extensive experience, including Mike Connor, former Navy Vice Admiral in charge of the U.S. Nuclear Submarine Fleet, as well as Shawn Matthews, former CEO of Cantor Fitzgerald & Co.
Today, the Company is engaged with engineers, regulators, suppliers and industrial partners to build, license and commission IMSR plants for fleet operation in the 2030s.

Revenue
Streams
Terrestrial Energy’s CAPEX-light business model and flexible energy output delivers competitive and customized solutions to customer-specific requirements across a 50+ year IMSR plant lifecycle, enabling sustainable, long-term revenue streams. Terrestrial Energy’s services include the delivery of engineering and construction services for commissioning IMSR plants, supply of critical components to construct and operate IMSR plants including long-term supply of replacement IMSR core-units every 7 years and IMSR fuel, in addition to operating, maintenance and decommissioning services. End-users are industrial and municipal counterparties requiring low-cost, clean, firm, high-temperature heat and/or electrical power, including data center operators and utilities, among others.
The high-margin plant economics of Terrestrial Energy’s IMSR plants derive from its reactor technology and plant design choices. The high thermal stability of molten salt coolant allows for high-temperature and low-pressure operation, with inherent safety attributes, all economic virtues. This drives high capital and operating efficiencies for low-cost heat and power, resulting in improved power plant revenue and profitability. The IMSR’s high-temperature heat supply enables a 50% increase in the efficiency of electric power generation compared to legacy nuclear technologies, which it achieves with low-cost, standard industrial turbines. Furthermore, the IMSR avoids the complexity and costs of high-pressure nuclear systems, structures, and components, contributing to lower plant CAPEX, improved affordability, and lower-cost electric power compared to legacy nuclear power plants.
Terrestrial Energy has partnerships and agreements in place with Westinghouse Fuel, Energy Solutions, Schneider Electric, the U.S. Department of Energy, and Argonne National Laboratory, among others. The company has a portfolio of multiple IMSR plant projects, which are sourced from a portfolio of consortium relationships. These are offering sites, construction, fuel supply, plant operating services, as well as heat and power offtake, with the capabilities to deliver further IMSR plant projects. They cover a range of deployment use-cases including co-location for data center power supply, co-located industrial plant heat and power supply, and distributed on-grid generation.

IMSR
Plants
In April 2023, Canada’s CNSC completed its multi-year Vendor Design Review (VDR) of the IMSR plant design and no fundamental barriers to licensing IMSR for commercial use were identified. The IMSR was the first Generation IV reactor design to complete this CNSC VDR, a historic first for a nuclear plant powered with molten salt reactor technology. The Company’s U.S. Nuclear Regulatory Commission (NRC) engagement commenced in 2016 and includes a successful interagency joint review of the IMSR technology under a CNSC-U.S. NRC Memorandum of Cooperation and concurrent with the CNSC’s completion of the Vendor Design Review. The Company and IMSR plant development have benefitted from multiple grant awards from the U.S., U.K., and Canadian governments, which have supported regulatory actions, reactor design and fuel supply development.
Additionally, Terrestrial Energy’s IMSR plant design is well-suited for repurposing existing and recently retired coal plants, maintaining firm power generation for grid reliability with clean and air pollution-free nuclear powered electricity generation. In 2022, DOE commissioned a report that found 80% of all retired and operating coal power plant sites can host an advanced nuclear reactor, totaling 290 sites, in addition to identifying significant primary and secondary environmental and economic benefits of IMSR technology for these applications. This represents up to 174 GW of potential replacement capacity to be met with IMSR plants in the U.S. alone as of April 2024, according to DOE.
