Enable completion of site characterization work necessary for NRC permitting and commercial IMSR Plant construction

Support development of the Department of Energy authorized Reactor and Fuel Line Pilot Projects

Advance IMSR Plant commercial pipeline and testing activities supporting NRC operating licensing

Terrestrial Energy Inc. (NASDAQ:IMSR), a developer of small modular nuclear power plants using its Generation IV Integral Molten Salt Reactor (IMSR), and The Texas A&M University System (A&M System) have signed ground lease and R&D agreements. These agreements provide exclusive access and rights to approximately 77 acres at the Texas A&M-RELLIS campus in Bryan, Texas, facilitate testing activities, and cover multiple projects, including the planned commercial IMSR Plant at A&M-RELLIS.

The projects were initiated following the Memorandum of Understanding (MOU) with the A&M System announced in 2025 after its selection of Terrestrial Energy to participate in its Energy Proving Ground initiative, which was established to bring advanced nuclear capacity to the campus. The initiative echoes nuclear policy objectives established by Governor Abbott and the Texas state legislature to catalyze development of advanced nuclear technologies in Texas and their rapid deployment on the ERCOT grid, one of the fastest-growing electricity markets in the country. Growing demand for reliable electricity from data centers, advanced manufacturing, industrial expansion, and other energy-intensive applications continues to drive interest in new sources of firm, carbon-free generation across Texas.

The agreements provide Terrestrial Energy with site control and exclusive access to 77 acres of adjoining land situated within the RELLIS Energy Proving Ground and enable project development, including the involvement of engineering, supply chain and other project partners. Importantly, they allow Terrestrial Energy to complete necessary site characterization and environmental evaluations, activities that started in 2025 and which will provide the detailed site data required for an application to the NRC for a permit to construct an IMSR Plant and for additional buildings and facilities. These activities are subject to further approvals by The A&M System's Board of Regents in advance of nuclear activities.

These include facilities to support IMSR testing activities as well as the Company's DOE partnership projects: TETRA and TEFLA. Important elements of these planned testing activities will be undertaken in close collaboration with the A&M System under the direction of a Master Research Agreement signed in the first quarter of 2026. In preparation, the Company has opened an engineering and project management office at the RELLIS campus. Its staff will direct and advance the multiple A&M-RELLIS site projects in partnership with the A&M System and other stakeholders; the Company has also joined the Greater Brazos Partnership and has participated in workforce development and industry initiatives supporting the growth of advanced nuclear in Texas.
