(NASDAQ: IMSR) (“Terrestrial Energy” or “the Company”), a developer of Generation IV small modular nuclear power plants, today announced its financial results for the first quarter ended March 31, 2026.\n\n\n“During the quarter, Terrestrial Energy delivered against the three-pillar framework outlined in March – IMSR engineering and regulatory programs, including our key project engagements with the U.S. Department of Energy, supply chain development, and our commercial pipeline of IMSR Plant projects,” said Simon Irish, CEO of Terrestrial Energy. “These developments move us closer to serving large industrial markets and the opportunity to power AI, advanced manufacturing, and the broader U.S. economy.”\n\n\nEngineering and Regulatory Highlights:\n\n\n\nTerrestrial Energy signed two Other Transaction Authority (OTA) agreements with the U.S. Department of Energy advancing TETRA, the reactor pilot project, and TEFLA, the fuel line pilot project. The projects support engineering and regulatory programs for IMSR plant commercial operation and infrastructure development for IMSR plant fuel supply.\n\n\n\nThe U.S. Nuclear Regulatory Commission (NRC) approved the Company’s Postulated Initiating Events methodology (PIE) Topical Report and issued its Safety Evaluation Report (SER). This follows the NRC’s acceptance of the Company’s final Topical Report submission announced in April 2026. The NRC’s approval of Terrestrial Energy’s PIE methodology delivers the framework to identify and evaluate events that may challenge the safe operation of IMSR nuclear plant. This analysis is foundational to nuclear safety and represents another important regulatory milestone as Terrestrial Energy systematically executes on its nuclear regulatory program with the NRC.\n\n\n\nThe PIE Topical Report follows on from the NRC’s September 2025 approval of IMSR’s Principal Design Criteri...
