• The company's business model relies on successful execution of complex, long-term projects.
• Forward-looking statements are subject to significant risks and uncertainties.
• The company has not yet generated significant revenue from plant operations.

Risks

• Risks related to the development, manufacturing, and construction of IMSR Plants, including potential delays and cost overruns.
• Ability to obtain applicable regulatory approvals and licenses on a timely basis.
• Adverse effects from economic, business, and competitive factors, including alternative energy technologies and energy price volatility.
• Potential supply chain constraints and cost inflation for specialized nuclear-grade materials and components.
• Failure to comply with laws and regulations governing the use, transportation, and disposal of hazardous materials.
• Changes in domestic and foreign business, market, financial, and political conditions, and applicable laws and regulations.
• The ability to raise additional funding in the future.
• The outcome of any legal proceedings that may be instituted against the Company.

Future Outlook

The company anticipates significant progress in 2026 across four key pillars: engineering developments and regulatory approvals (including submission of further topical reports and construction of DOE partnership pilot reactors), supply chain developments and expansion (including material qualification and fuel line pilot construction), IMSR Plant project pipeline developments (including announcement of additional projects and securing site control), and the commencement of construction phase revenues. Commercial operation of IMSR Plants is targeted for the 2030s, with a path to fleet-scale deployment and a significant share of the ~$2.3 trillion SAM by 2050.

Management Comments

• The IMSR is the most capital-efficient SMR for rapid deployment at scale.
• The IMSR Plant delivers low-cost nuclear energy using readily available LEU fuel, modular design for fast construction, and regulatory leadership.
• High-temperature thermal energy supply delivers ~50% greater steam-turbine efficiency than nuclear plants that use light-water reactor technology.
• Terrestrial Energy's capital-light model captures a Serviceable Addressable Market growing to $2.3T by 2050 with revenues starting during site development and construction, extending 50+ years.
• The IMSR Plant addresses the weaknesses and limitations of LWR technology with best-in-class Gen IV reactor technology.
• The IMSR's triple advantage – high-temperature, low-pressure operation with high inherent safety – combined with LEU fuel, delivers best-in-class capital efficiency with speed to fleet scale.

Industry Context

StockSavvy.ai notes that Terrestrial Energy's presentation aligns with the growing global demand for advanced nuclear technologies, particularly Small Modular Reactors (SMRs), driven by decarbonization goals, energy security concerns, and the increasing power needs of data centers. The company's focus on Generation IV technology, specifically molten salt reactors, positions it within a segment of the nuclear industry aiming for enhanced safety, efficiency, and economic competitiveness compared to traditional Light Water Reactors (LWRs).

Comparison to Industry Standards

• Compared to traditional Light Water Reactors (LWRs), the IMSR offers a higher thermal supply temperature (585°C vs. ~270°C), leading to a net thermal efficiency of 44% for electricity generation versus ~30% for LWRs.
• The IMSR operates at low pressure (1 bar) compared to high pressure (55-150 bar) for LWRs, simplifying design and reducing costs.
• Unit capital costs for IMSR are estimated at ~$1-2 billion upfront (NCP status) compared to over $10 billion upfront for LWRs.
• Levelized Cost of Heat for IMSR is $8.60/MMBTU, while LWRs are not typically used for direct heat supply in this context.
• Levelized Cost of Electricity for IMSR is $69/MWh, significantly lower than the >$140/MWh for LWRs (based on Lazard's June 2024 data).
• IMSR has a 7-year fuel cycle compared to 18-24 months for LWRs.
• IMSR produces 32% less fission product waste per kWh(e) by mass compared to LWRs.
• Other Gen IV reactor types like HTGR and SFR are noted to have lower capital efficiency, higher pressure/temperature complexities, and more constrained supply chains (e.g., requiring HALEU fuel).

Stakeholder Impact

• Shareholders: Potential for long-term value creation if the IMSR technology is successfully deployed and commercialized, but also subject to the risks inherent in early-stage technology companies.
• Employees: Growth in employment opportunities as the company scales its operations, R&D, and project development.
• Customers (Industrial, Data Centers, Utilities): Access to a new source of clean, firm, low-cost thermal energy and electricity, potentially reducing reliance on fossil fuels and improving operational efficiency.
• Suppliers: Opportunities for suppliers of engineering, components, fuel, and services to participate in the development and deployment of IMSR plants.
• Creditors: Potential for future financing needs, with the company's success impacting its ability to service debt.

Next Steps

• Submission of at least two further IMSR Topical Reports to the NRC.
• Construction of DOE partnership TETRA pilot reactor.
• Construction and operation of DOE partnership TETRA pilot reactor.
• Submission and approval of NRC Construction Permit for commercial IMSR Plant.
• Testing data from NRG, TETRA, and others to advance readiness for NRC Operating License applications.
• Construction and operation of DOE partnership TEFLA fuel line pilot.
• Selection and commencement of construction for IMSR Core-unit manufacturing and fuel production plants.
• Announcement of details for 1 to 3 additional IMSR Plant projects in FY 2026.
