Terrestrial Energy(NASDAQ) IMSR

Terrestrial Energy Inc. designs advanced nuclear power plants. These plants provide clean heat and electricity for large factories. The technology helps industrial companies move away from fossil fuels.

What Is an IMSR Plant?

• Integral Molten Salt Reactor: Advanced reactor design using molten salt as both fuel and coolant to provide stable, high-temperature heat.
• Industrial Thermal Energy: Direct heat supply for industrial processes, serving as an alternative to burning fossil fuel combustion.
• Grid-Based Electricity: Electric power generation using steam turbines driven by the reactor's thermal output.
• Standard Nuclear Fuel: Design choice to use existing, proven fuel types to speed up the transition from design to operation.

Steps Toward Commercial Power

• Completed a business combination with HCM II Acquisition Corp on Oct. 28, 2025, to become a publicly traded company.
• Executed agreements with the U.S. Department of Energy (DOE) in Dec. 2025 and Jan. 2026 to develop pilot reactor and fuel production projects.
• Partnered with Riot Platforms on May 6, 2026, to design nuclear-powered data centers for large-scale hyperscale tenants.
• Signed ground lease and research agreements with the Texas A&M University System on June 18, 2026, to facilitate site testing activities.

Breaking the Nuclear Mold

Terrestrial Energy uses a proprietary design that integrates the reactor, steam generator, and pumps into a single replaceable unit. This design focuses on affordability and safety by using inherent power dynamics to maintain stability without complex external systems.

Counting the Cost of Innovation

• Net loss was $9,399,000 in the three-month period ended June 30, 2026, up 50% year over year.
• Research and development costs reached $8,064,000 for the six-month period ended June 30, 2026, up 183% year over year.
• Total operating expenses were $23,603,000 for the six-month period ended June 30, 2026, up 135% year over year.
• Cash and cash equivalents totaled $130,737,000 as of June 30, 2026.
• Market capitalization was $636.2 million in Q1 2026, down 69.4% year over year.

The Road Ahead

Terrestrial Energy has transitioned from a private developer to a public company focused on commercializing its proprietary reactor technology. Its strategy relies on regulatory milestones and government partnerships to bring modular nuclear heat and power to the global market by the mid-2030s.
