Terrestrial Energy Inc Stock Price, News & Analysis

Terrestrial Energy (NASDAQ: IMSR) executed an Other Transaction Authority (OTA) agreement with the U.S. Department of Energy to build and operate Project TEFLA, a pilot plant to demonstrate IMSR Fuel Salt production using standard-assay low-enriched uranium (SALEU <5% U235) feedstock. TEFLA is part of the DOE Fuel Line Pilot Program under Executive Order 14301 and will support the Company’s Project TETRA test reactor. DOE will review TEFLA design for safe handling and expedite authorization, enabling faster development of IMSR fuel supply and commercial reactor deployment.

Terrestrial Energy says its commercial IMSR plant design produces 822 MWth (390 MWe) and avoids HALEU reliance.

Terrestrial Energy (NASDAQ: IMSR) will present at the 28th Annual Needham Growth Conference on January 13, 2026 in New York. The Company is scheduled to present at 2:15 p.m. ET and will provide a live webcast and replay via its investor relations website. Senior leaders Simon Irish, Chief Executive Officer, and Brian Thrasher, Chief Financial Officer, are expected to attend and be available for one-on-one meetings. Investors and analysts can access the webcast on the company’s IR site and contact their salesperson to arrange one-on-one meetings.

Terrestrial Energy (NASDAQ: IMSR) executed an Other Transaction Authority (OTA) agreement with the U.S. Department of Energy on Jan. 6, 2026 to construct and operate Project TETRA, a pilot Integral Molten Salt Reactor (IMSR).

The OTA enables a streamlined DOE authorization to move from design to operation, supports commercialization of IMSR plants, and complements the company's Sept. 2025 selection for the DOE Fuel Line Pilot Program. The IMSR commercial design is specified at 822 MWth (390 MWe) and uses SALEU fuel <5% U-235 to avoid HALEU dependence.

Terrestrial Energy (NASDAQ: IMSR) will participate in two investor conferences in December 2025: the B. Riley Securities Convergence Conference: AI, Blockchain & Energy on December 4, 2025 in New York City, and the 2nd Annual Craig-Hallum Nuclear Energy Forum on December 11, 2025 (virtual).

Senior leadership including CEO Simon Irish and CFO Brian Thrasher will host one‑on‑one investor meetings at both events; investors should contact their salesperson to schedule meetings.

Terrestrial Energy (NASDAQ: IMSR) announced two senior hires to accelerate U.S. commercialization of its Integral Molten Salt Reactor (IMSR): Jim Howe as VP of Government Relations and David O’Keefe as VP of Business Development & Project Management.

The company said Howe will deepen federal and Texas engagements for the RELLIS commercial site and O’Keefe will lead commercial delivery, DOE and national-lab coordination, and pipeline growth. Recent milestones cited include RELLIS site selection (Feb 2025), a DOE Advanced Reactor Pilot award targeting initial criticality by July 4, 2026 (Project TETRA, Aug 2025), selection for DOE Fuel Line Pilot (Sept 2025), an Ameresco collaboration, and an expanded Westinghouse fuel-pilot contract starting in 2026.

Terrestrial Energy (NASDAQ: IMSR) signed an expanded manufacturing and supply contract with Westinghouse’s Springfields to design and build an IMSR fuel pilot plant, with construction starting in 2026. The expanded scope covers deconversion, fabrication, packaging and transportation to support scaling to commercial fuel production for future IMSR plants.

The pilot plant design includes a re-optimized chemical process to produce UF4 deconverted from UF6 at 5% enrichment, enabling use of SALEU (under 5% U-235) and leveraging Springfields’ ~80-year SALEU manufacturing legacy. The deal complements Terrestrial Energy’s selection in U.S. DOE advanced reactor and fuel pilot programs and aims to accelerate IMSR commercialization while using established transport and regulatory protocols.

Terrestrial Energy (NASDAQ: IMSR) announced on Nov 4, 2025 the appointment of Sarfraz M. Taj as Vice President of Business Development to support commercialization of the Integral Molten Salt Reactor (IMSR).
