Lightbridge Provides Business Update and Announces First Half Fiscal 2026 Financial Results

About this update from Lightbridge Corporation

RESTON, Va., Aug. 05, 2026 (GLOBE NEWSWIRE) -- Lightbridge Corporation ("Lightbridge" or the "Company") (Nasdaq: LTBR), an advanced nuclear fuel technology company, announced its financial results for the second quarter and first half of fiscal year 2026, and provided an update on the Company's continued progress. Seth Grae, Chairman & Chief Executive Officer of Lightbridge, commented, "In the first half of 2026, our fuel development work at Idaho National Laboratory produced its first irradiated material for examination. In May, the first batch of our fuel material samples was removed from the Advanced Test Reactor with members of our engineering team and senior management present. Those samples are now cooling ahead of post-irradiation examination (PIE), which we expect to begin later this year. The PIE will produce our first material property data under high burn-up conditions, while irradiation of the remaining samples continues. We also received notices of allowance from the U.S. Patent and Trademark Office covering our multi-lobed fuel assembly for pressurized heavy water reactors, and from the European Patent Office covering our multi-zone fuel element and its additive manufacturing method across 39 contracting states." "In May, we partnered with Studsvik Scandpower to develop an extension of the Studsvik CMS5 Core Management Suite to model the new Lightbridge Fuel™ design, placing our design inside the state-of-the-art software that utilities already rely on worldwide. Then in June, I represented Lightbridge at the White House launch of UPRISE, the Department of Energy initiative targeting approximately 5 GW of end capacity drawn from reactors already operating. As electricity demand accelerates, driven by AI and hyperscale data centers, the fastest and least expensive additional nuclear-generated megawatts will come from increasing the power output of currently operating reactors. Lightbridge Fuel is being designed to deliver the largest power uprates available while enhancing safety and operating at approximately 1,000°C cooler than conventional fuel." "Since the quarter end, we signed a memorandum of understanding with Quadrant Nuclear Industries to establish a framework for long-term HALEU supply from its planned Vanguard facility at Idaho National Laboratory. Securing domestic fuel supply is work that has to be done years before the fuel is needed, and we intend to be early rather than late. Lightbridge was also added to the Solactive Global Uranium & Nuclear Components Total Return Index, the benchmark that is tracked by the Global X Uranium ETF, beginning earlier this week. As with the Russell indexes, joining this prestigious index broadens the base of investors with ownership of our stock." Financial Highlights Working capital was approximately $236.4 million at June 30, 2026, compared to $201.7 million at December 31, 2025. Cash Flows Summary At June 30, 2026, the Company had cash and cash equivalents of $237.5 million, as compared to $201.9 million at December 31, 2025, an increase of $35.6 million, consisting of the following: Second Quarter 2026 Operations Summary Six Months Ended June 30, 2026 Operations Summary CONFERENCE CALL & AUDIO WEBCAST Lightbridge will host a conference call on Thursday, August 6, at 4:00 p.m. ET with the investment community to discuss the Company's financial results and provide an update on its fuel development activities.
