CHARLOTTE, N.C.--(BUSINESS WIRE)--Terrestrial Energy Inc. (NASDAQ: IMSR) (“Terrestrial Energy” or “the Company”), a leader in Generation IV molten salt nuclear plants supplying electricity and high-temperature industrial heat, today announced its financial results for the third quarter ended September 30, 2026.
“Our selection for Ameresco’s project with the U.S. Army extends our commercial pipeline into the federal government and defense, and with our Thermal and Electric Facility Topical Report, we delivered on our guidance of at least three submissions to the NRC this year,” said Simon Irish, Chief Executive Officer of Terrestrial Energy. “We are focused on the race to fleet deployment, and on delivering nuclear power at fleet scale. The world needs innovative nuclear plants for new sources of clean, firm, affordable energy, and those fundamentals continue to strengthen supporting our business plan.”
Engineering and Regulatory Highlights:
- Submitted its Graphite Topical Report to the U.S. Nuclear Regulatory Commission (NRC), seeking approval of the Company’s methodology to qualify graphite for the IMSR Core-unit.
- Submitted the Thermal and Electric Facility (TEF) Topical Report after quarter end, seeking NRC confirmation that the TEF is a non-nuclear part of the IMSR Plant that can be constructed and operated without NRC permits or licenses. The submission completes the Company’s 2026 guidance of at least three Topical Reports.
Supply Chain Developments:
- Commenced engineering work with Zachry Nuclear under the Engineering Services Agreement, supporting site characterization and NRC Construction Permit application work at the Texas A&M-RELLIS site.
- Developed fuel, component and services supply for Projects TETRA and TEFLA.
Commercial Pipeline of IMSR Plant Projects:
- Selected as the advanced nuclear technology supplier for Ameresco, Inc.’s (NYSE: AMRC) power project at the U.S. Army’s Aberdeen Proving Ground in Maryland, the second IMSR Plant project the Company has disclosed this year. This is in line with guidance provided at the beginning of the year, to announce details on one to three additional projects. The Army selected Ameresco through a competitive process under its Strategic Capital Initiatives, a program for partnering with private capital to modernize military installations. The selection builds on the parties’ June 2025 Memorandum of Understanding.
- Appointed David Williams as Chief Commercial Officer after quarter end, effective October 19, 2026, bringing four decades of power sector experience including senior roles at Kiewit Nuclear Solutions and Fluor.
Performance, Liquidity and Capital Structure:
- Reported a net loss of $11.0 million, compared to a net loss of $9.4 million for the second quarter 2026. This change was primarily driven by:
- $0.9 million increase in R&D, including fuel testing and lease costs related to RELLIS.
- $0.5 million increase in G&A due to stock-based compensation, driven by awards to new hires as the Company grows its management resources and headcount.
- Ended third quarter with $276.3 million in Cash and Cash Equivalents and Short-term Investments, compared to $283.4 million at second quarter end, with total liabilities of $8.6 million and no debt.
- Reported cash burn of $7.1 million, an increase of $0.7 million compared to second quarter. The increase largely reflects higher R&D activity associated with fuel development and testing. The Company expects cash burn to increase as it ramps projects in future quarters, including TETRA and TEFLA.
- Ended third quarter with 105.9 million shares issued and outstanding, unchanged from second quarter end, consisting of 82.7 million common shares and 23.2 million exchangeable shares.
- Authorized a share repurchase program of up to $25 million of the Company’s common stock, funded with existing cash on hand, subsequent to quarter end.
