Successful Public Listing and Financing
Completed business combination with HCM II and began trading on NASDAQ (IMSR) on October 29, 2025; transaction generated more than $292 million in gross proceeds including a $50 million PIPE and resulted in year-end cash and short-term investments of approximately $298 million.
Regulatory Milestone — NRC Topical Report Accepted
NRC completed and accepted the Topical Report on the IMSR Principal Design Criteria in 2025, a foundational step toward operating license submission and demonstrating progress with pre-application engagement.
Federal Support via DOE OTA Awards
Received two OTA awards from DOE programs established in 2025: one from the Advanced Reactor Pilot Program to support Project TETRA (test reactor assembly) and one from the Fuel Line Pilot Program to support TEFLA (pilot fuel production).
Strategic Supply Chain & Industry Partnerships
Expanded supplier relationships with major nuclear and industrial partners (Westinghouse, Siemens Energy, BWXT) and announced further contracts with Westinghouse to support IMSR fuel supply readiness.
Commercial Project Progress
Texas A&M selected Terrestrial Energy to site a full-scale commercial IMSR plant at the RELLIS campus; announced collaboration with Ameresco to broaden project identification and development capacity.
Technology and Market Differentiation
IMSR design uses standard nuclear fuel (<5% enrichment) (avoids HALEU), low-pressure high-inherent safety molten salt design, ~50% greater steam turbine efficiency versus light-water reactors, and design aims for smaller, modular, capital-efficient plants targeting a service addressable market estimated to exceed $1.4 trillion.
Near-Term 2026 Milestone Roadmap
Guidance for 2026 includes: further agreements with Texas A&M, disclosure of 1–3 additional commercial projects, submission of at least three additional NRC Topical Reports, and site/partner disclosures for TETRA and TEFLA — demonstrating a clear execution plan.
Materials Testing Progress
Advanced materials qualification work with graphite irradiation testing entering concluding phase at NRG PALLAS High Flux Reactor (Netherlands), supporting supplier selection and licensing readiness for Generation IV reactor materials.
