Terrestrial Energy Inc.

Terrestrial Energy did not report revenue or EPS on this call. At quarter end, the company had $283.4 million of total cash, cash equivalents, and short- and long-term investments, versus $289.9 million at the end of Q1 2026. Cash burn in Q2 was $6.4 million, or about $2.2 million per month, versus $7.9 million in Q1 2026, or about $2.6 million per month. R&D expense was down approximately $1.1 million sequentially, while G&A expense was up approximately $700,000, including a $500,000 increase in stock-based compensation. Management said updated unit economics show cumulative lifetime revenues per unit of approximately $2.7 billion, up from $2.1 billion, with blended gross profit margin of 33%, up from 22%; core unit gross margin was re-estimated at 33% and fuel supply at 40%. The serviceable addressable market was updated to $2.3 trillion by 2050, up from $1.9 trillion. No formal next-quarter or full-year financial guidance was given, but management reiterated that cash burn will increase during the second half of 2026 as testing, project activities, and organizational capacity expand.

Simon Irish framed the quarter as steady execution against the company’s three-pillar plan: engineering/regulatory progress, supply-chain buildout, and commercial pipeline development. He emphasized differentiation in the IMSR design, especially the company’s capital-light model, its fuel strategy, and the ability to support data centers and industrial users with a dual-fuel configuration that can start with natural gas and later transition to nuclear heat. His tone was confident and strategic, repeatedly describing the SMR/nuclear market as secular, growing, and supportive of Terrestrial Energy’s approach.

Brian Thrasher focused on disciplined spending and a clean balance sheet. He reported $283.4 million in cash, cash equivalents, and short- and long-term investments, down modestly from $289.9 million in Q1, and said quarterly cash burn was $6.4 million versus $7.9 million in the prior quarter. He attributed the lower burn mainly to timing shifts in testing activity, while noting spending will increase in the second half of 2026 as site analysis, testing, project work, and headcount expansion continue. He also said issued shares were unchanged, fully diluted shares rose by about 300,000, and the company has modest liabilities, lease obligations, and no debt.

Analysts pressed on what changed in the revised unit economics, and management said the model itself had not changed; the revisions came from engineering work over the last 18 months, especially around TEFLA, which prompted a re-estimation of the economics. Questions on DOE projects focused on near-term milestones, but management would only say TETRA and TEFLA remain active and important, without giving specific dates. Analysts also asked about natural-gas bridge fuel, fuel qualification, and the Riot Platforms partnership; management said the back end of the plant could be brought online within 5 years using standard industrial equipment, fuel qualification is a more straightforward process for a liquid-fuel reactor than for solid-fuel systems, and Riot is currently in preliminary site characterization with financing expected to be strategic and supported by state/federal policy rather than classic project finance.
