**Terrestrial Energy Announces Fourth Quarter and Full Year 2025 Results**

*Texas A&M University selected commercial IMSR plant for deployment at RELLIS campus*

*U.S. Department of Energy selected both Terrestrial Energy reactor pilot and fuel-line pilot projects for advanced reactor programs*

*NRC Accepted IMSR Principal Design Criteria Including Inherent Reactor Control Mechanisms*

*Completed business combination, raising approximately $292 million in gross proceeds*

**CHARLOTTE, N.C.** – **March 30, 2026** – Terrestrial Energy Inc. (NASDAQ: IMSR) ("Terrestrial Energy" or "the Company"), a developer of small modular nuclear power plants using its Generation IV Integral Molten Salt Reactor (IMSR) technology, today announced its financial results for the fourth quarter and full year ended December 31, 2025.

"The Company made strong progress in 2025 in key areas, regulatory readiness, fuel supply development, and IMSR plant project development from engagements with deployment partners and government stakeholders," said Simon Irish, CEO of Terrestrial Energy. "We continue into 2026 with the objective to advance with clearly defined development steps and milestones, and from aligning key program elements into a coordinated pathway to deploy IMSR plants at scale and delivering reliable, clean, firm energy to industrial markets."

**Fourth Quarter and Full Year 2025 Highlights:**

● Texas A&M University, supported by expertise in its nuclear engineering faculty, selected Terrestrial Energy to site a full-sized commercial IMSR Plant at its RELLIS campus following a competitive and sector-wide evaluation process. This selection positions the RELLIS campus project among the first commercial Generation IV reactor deployments on the ERCOT grid and provides an impressive platform to accelerate IMSR Plant development to commercial operations.

● The Company expanded commercial reach and ability to execute at greater scale across the United States from collaboration with Ameresco, Inc. (NYSE: AMRC), a leading energy solutions provider with strong federal procurement capabilities. This collaboration expands access to new opportunities, supports site identification and IMSR Plant project development, particularly projects benefiting from the IMSR Plant's customization capabilities. These include integration with other energy systems, such as natural gas, for early commercial operation and improved supply resilience, which strengthens Terrestrial Energy's ability to deliver competitive solutions for data center energy supply.

● The U.S. Nuclear Regulatory Commission (NRC) completed its safety evaluation and accepts Terrestrial Energy's Topical Report submission on IMSR Principal Design Criteria, which includes its mechanism for inherent reactor power control, important for load following commercial applications. This is an important step forward in licensing readiness for IMSR plant construction and operation.

● IMSR technology and the Company's fuel strategy for commercial use received strong validation from the U.S. Department of Energy (DOE) when Terrestrial Energy received two "OTA" awards, one from each of its pilot programs. The first from the DOE's Advanced Reactor Pilot Program, which supports quick execution of the TETRA project – the Terrestrial Energy Test Reactor Assembly project. The second was from the DOE's Fuel Line Pilot Program, which supports the Company's schedule for completion of Fuel Line Assembly project, TEFLA, the antecedent to Terrestrial Energy's commercial plant for IMSR Plant fuel supply. Together, these two projects provide an accelerated pathway for IMSR Plant licensing, commercial operation and fuel supply.

● Terrestrial Energy entered the concluding phase of its reactor graphite irradiation and supplier selection program at NRG PALLAS' High Flux Reactor in Petten, the Netherlands. These irradiation tests, conducted in one of the world's most powerful test reactors, represent a key step in supplier selection and graphite grade qualification required for IMSR Plant licensing and operation.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

● The Company successfully completed its business combination with HCM II Acquisition Corp, raising more than $292 million in gross proceeds, and began trading with a strengthened balance sheet on the Nasdaq under the ticker symbol IMSR.

● Terrestrial Energy announced a manufacturing and supply contract with Westinghouse, strengthening supply-chain readiness, and the company enhanced its senior leadership team to support U.S. commercialization efforts and deepen engagement with federal stakeholders.

**Performance, Liquidity and Capital Structure:**

● The Company reports a $28 million Net Loss for 2025, representing a $17 million increase from the prior year. The increase is attributable to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o A $5 million increase in R&D as the Company expanded materials testing and progressed graphite qualification work.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o A $10 million increase in G&A due to increased legal and accounting fees, personnel- related expenses and stock-based compensation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o A $2 million increase in interest expense due to higher debt balances and amortization of debt discount.

● As of December 31, 2025, the Company held approximately $298 million in cash and short-term investments.

● As of December 31, 2025, 105.8 million shares were issued and outstanding. This consisted of approximately 81.8 million common shares and 24.0 million exchangeable shares, exchangeable into common shares on a one-for-one basis at the option of the holder.

**2026 Outlook:**

● The Company will provide an update on expected 2026 milestones, including commercial, regulatory and development progress, during the earnings call.

**About Terrestrial Energy**

Terrestrial Energy is a developer of Generation IV nuclear plants that use its proprietary Integral Molten Salt Reactor (IMSR). The IMSR captures the transformative operating benefits of molten salt reactor technology in a plant design that represents true innovation in capital efficiency, cost reduction, versatility and functionality of nuclear energy supply. IMSR plants are designed to be small and modular for distributed supply of low-cost, reliable, dispatchable, clean, high-temperature industrial heat and electricity and to be customized for a dual-use energy role relevant to many industrial applications, such as petrochemical and chemical synthesis and data center operation. In so doing, IMSR plants extend the application of nuclear energy far beyond electric power markets. Their deployment will support the rapid growth of clean firm heat and power, delivering energy self-reliance, grid reliability and economic growth. Terrestrial Energy uses an innovative plant design together with proven and demonstrated molten salt reactor technology and readily-available and inexpensive standard-assay low-enriched uranium in its fuel for a nuclear plant with a unique set of operating characteristics and compelling transformative commercial potential. Terrestrial Energy is engaged with regulators, suppliers, industrial partners and energy end-users to build, license and commission the first IMSR plants in the early 2030s.
