Terrestrial Energy Inc. reported a net loss of $10,503 (amounts in thousands) for the three months ended March 31, 2026, unchanged at $(0.10) per share versus 2025 due to higher share count. Operating expenses more than doubled to $11,931, driven by increased research and development spending of $4,566 and general and administrative costs of $7,304 as the company scales its Integral Molten Salt Reactor program.
Despite higher losses, Terrestrial Energy ended the quarter with $76,946 in cash and cash equivalents and $198,018 in short-term investments, supporting net working capital of $271,695 and total assets of $295,168. Management believes this liquidity, enhanced by more than $292,000 of gross proceeds from its late‑2025 business combination and related financing, is sufficient to fund operations for at least the next twelve months while it advances IMSR development and DOE-supported pilot projects.

Terrestrial Energy Inc. updated employment agreements for three senior executives, clarifying pay, bonuses, equity eligibility and severance protections.
Chief Financial Officer Brian Thrasher will receive a $350,000 base salary, a target bonus equal to 43% of salary, and potential equity awards under the 2025 Equity Incentive Plan. If terminated without cause, he is eligible for six months of salary, a pro rata bonus for the year of termination, partial acceleration of time-based equity vesting over the next six months, and COBRA premium reimbursement during the severance period, subject to a release and restrictive covenants.
Chief Operating Officer William Smith will receive a $330,000 base salary, a 20% target bonus and equity award eligibility under the same plan. If his employment ends without cause, his agreement mirrors Thrasher’s in most respects, but instead of COBRA reimbursements it provides continuation of benefits required under Canadian law and extended group health and dental coverage for up to six months, or until he joins another employer plan.
Chief Technology Officer and director David LeBlanc will receive a $250,000 base salary, a 20% target bonus and equity award eligibility, with severance and post-termination non-compete and non-solicitation terms aligned to Smith’s. Overall, the changes formalize compensation and severance terms while adding six-month restrictive covenant periods for these executives.
