**Terrestrial Energy Reports First Quarter 2026 Results**

*Completed OTA contract with Department of Energy supporting IMSR pilot reactor and IMSR fuel pilot plant projects* 

*Collaboration with Riot Platform for a best-in-class pairing of data center and co-located nuclear plant to deliver up to 4GW of nuclear power capacity for hyperscale AI operation*

*NRC approved Topical Report on IMSR Postulated Initiating Event methodology and issued Safety Evaluation Report*

**CHARLOTTE, N.C.** — **May 14, 2026** — Terrestrial Energy Inc. (NASDAQ: IMSR) ("Terrestrial Energy" or "the Company"), a developer of Generation IV small modular nuclear power plants, today announced its financial results for the first quarter ended March 31, 2026.

"During the quarter, Terrestrial Energy delivered against the three-pillar framework outlined in March – IMSR engineering and regulatory programs, including our key project engagements with the U.S. Department of Energy, supply chain development, and our commercial pipeline of IMSR Plant projects," said Simon Irish, CEO of Terrestrial Energy. "These developments move us closer to serving large industrial markets and the opportunity to power AI, advanced manufacturing, and the broader U.S. economy."

**Engineering and Regulatory Highlights:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Terrestrial Energy signed two Other Transaction Authority (OTA) agreements with the U.S. Department of Energy advancing TETRA, the reactor pilot project, and TEFLA, the fuel line pilot project. The projects support engineering and regulatory programs for IMSR plant commercial operation and infrastructure development for IMSR plant fuel supply.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The U.S. Nuclear Regulatory Commission (NRC) approved the Company's Postulated Initiating Events methodology (PIE) Topical Report and issued its Safety Evaluation Report (SER). This follows the NRC's acceptance of the Company's final Topical Report submission announced in April 2026. The NRC's approval of Terrestrial Energy's PIE methodology delivers the framework to identify and evaluate events that may challenge the safe operation of IMSR nuclear plant. This analysis is foundational to nuclear safety and represents another important regulatory milestone as Terrestrial Energy systematically executes on its nuclear regulatory program with the NRC.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The PIE Topical Report follows on from the NRC's September 2025 approval of IMSR's Principal Design Criteria Topical Report. Together, these two Topical Reports establish foundational elements of the IMSR licensing basis for commercial operation. In addition they can now be referenced in future licensing applications without re-evaluation, reducing the scope of subsequent technical review and increasing confidence of the licensing critical path.

**Supply Chain Developments:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Company's materials' testing and qualification programs continued during the quarter, including graphite irradiation at one of the world's most powerful test reactors. These activities are essential for reactor materials' qualification, supplier selection, and licensing readiness.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Relationships with nuclear industry suppliers remained in active execution for materials, component and services supply, supporting the fabrication of reactor components and the development of fuel supply infrastructure.

**Commercial pipeline of IMSR Plant Projects:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On May 6, 2026, the Company executed a Memorandum of Understanding with Riot Platforms, Inc. (NASDAQ: RIOT), a leader in large-scale data center development, to co-locate IMSR Plants with Riot-developed data centers and create a best-in-class data center – nuclear plant pairing to serve AI and high-performance compute applications. The collaboration contemplates deployment of multiple IMSR Plants representing up to 4GW of nuclear power capacity across multiple sites. The companies will jointly evaluate sites and the opportunities to incorporate a natural gas fuel bridge for fast commercial power supply and to enhance supply resiliency during full nuclear power plant operation.

**Performance, Liquidity and Capital Structure:**

● For the quarter, Terrestrial Energy reported a net loss of $10.5 million, compared to a net loss of $6.2 million for the fourth quarter 2025. This change was primarily driven by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o $3.2 million increase in R&D as the Company progressed fuel development and graphite testing programs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o $4.0 million increase in G&A due to increased personnel-related expenses and stock-based compensation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o $2.8 million increase in Other Income (Expense) due to decreased Interest Expense and an increase in Interest and Dividend Income.

------

The Company ended the quarter with a strong balance sheet, reporting $289.9 million in cash and investments as of March 31, 2026. This liquidity provides a substantial runway to deliver important developments across the three pillars of the IMSR plant development and commercialization.

During the quarter, the Company reported cash burn of $7.9 million, an increase of $1.8 million compared to the prior quarter after consideration of one-time transaction costs associated with the merger. Two items drove much of the increase: a first quarter 2026 payment of $0.6 million for 2025 discretionary bonuses; and, $1.0 million paydown of accounts payable to vendors offering extended credit terms. The remaining $0.2 million increase of first quarter cash burn is attributable to higher sequential payments for research and development.

At quarter end 105.9 million shares were issued and outstanding, which is largely unchanged from December 31, 2025. This consisted of 82.2 million common shares and 23.7 million exchangeable shares, the latter exchangeable into common shares on a one-for-one basis at the option of the holder.

**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.
