Lightbridge Provides Business Update and Announces Fiscal Year 2025 Financial Results

RESTON, Va., February 25, 2026 (GLOBE NEWSWIRE) – Lightbridge Corporation (“Lightbridge” or the “Company”) (Nasdaq: LTBR), an advanced nuclear fuel technology company, announced its financial results for the fiscal year ended December 31, 2025, and provided an update on the Company’s continued progress.

Seth Grae, President & Chief Executive Officer of Lightbridge Corporation, commented, “2025 was an important year for Lightbridge and the nuclear power industry. Governments, utilities, and leading tech companies agree with our conclusion that reliable, clean nuclear power is necessary to meet the growing demand for electricity from AI and data centers, address rising energy costs, and help achieve energy independence.”

“In 2025, we reached key milestones in our fuel development program. Our team, in collaboration with Idaho National Laboratory, successfully co-extruded samples of depleted and enriched uranium-zirconium alloy and began testing them in the Advanced Test Reactor. These are important steps in demonstrating the performance of Lightbridge Fuel material and its potential use in both light-water reactors and future small modular reactors.”

“The policy environment for nuclear energy has never been better. President Trump’s nuclear executive orders in May 2025 show that the U.S. is making nuclear power expansion a national priority. The directives aim to add 300 gigawatts of nuclear capacity by 2050 (the equivalent of 300 large reactors), make regulations easier to follow, and deploy advanced reactors for national security. At the same time, major technology companies are demonstrating unprecedented commitment to nuclear energy.”

“We expect 2026 to be an exciting year for Lightbridge,” concluded Mr. Grae.
