Earnings Recap — Q2 FY2026
CY Q3 2026 · Reported August 11, 2026 · Beat 0 of last 2 quarters
The Buildout is a website built on agentic AI tools, currently in beta, and could have factual errors.
Terrestrial Energy's updated unit economics and expanded pipeline underscore the growing demand for firm, clean power from AI data centers. The Riot Platforms MOU and natural gas bridge fuel strategy highlight the need for speed to power in the AI infrastructure buildout. The company's fuel supply differentiation could reduce supply chain complexity for advanced nuclear deployment.
Terrestrial Energy reported Q2 2026 cash and investments of $283.4 million, with quarterly cash burn of $6.4 million, down from $7.9 million in Q1. The NRC approved the Postulated Initiating Events topical report in May, following the prior PDC approval. The company signed a ground lease with Texas A&M for a 77-acre site at RELLIS and announced an engineering services agreement with Zachry Nuclear. Unit economics were revised upward, with lifetime revenue per plant rising to $2.7 billion and blended gross margin to 33%. The commercial pipeline grew to 7.8 GW with the Riot Platforms MOU.
Management reiterated its 3-pillar execution framework and expects cash burn to increase in the second half of 2026 as site characterization at Texas A&M RELLIS and testing programs ramp. They raised their serviceable addressable market to $2.3 trillion by 2050, up from $1.9 trillion, driven by updated unit economics. The Riot Platforms relationship is targeting 4 GW of IMSR generation, with site down-selection as the next step. Management emphasized a capital-light model focused on core unit and fuel salt supply, with long-dated contracts securing recurring revenue.
“Our business is to manufacture and supply to operating plants IMSR core units, a major reactor component, designed to be replaced every 7 years over the plant's 56-year design life.”
on Business model
“In contrast to virtually all other SMRs in the nuclear tech sector today, whether those using Generation III or IV technologies, IMSR fuel salt production stops at step 2.”
on Fuel strategy
“We would anticipate because the back end of that plant would consist of standard industrial equipment, being able to bring power online commercially within 5 years.”
on Natural gas bridge fuel
Is the change in unit economics a fine-tuning of estimates or a fundamental change in approach?
Simon Irish said nothing fundamentally changed; the update reflects engineering work over the last 18 months, particularly TEFLA, and is an opportunity to highlight the principal businesses.
How long will plants use natural gas as a bridge fuel, and what are the economics during that period?
Simon Irish said the back end can be brought online commercially within 5 years using natural gas, with capital-efficient dual-purpose systems. This addresses data center demand for speed to power, with nuclear providing long-term clean firm power.
What additional topical reports are needed, and where are you in fuel qualification?
Simon Irish said two more topical reports are expected this year. Fuel qualification for liquid fuel is different—it focuses on demonstrating heat transport properties of the salt, not fuel pin performance, making it more straightforward.
