Lightbridge Provides Business Update and Announces First Quarter 2026 Financial Results

RESTON, Va., April 27, 2026 (GLOBE NEWSWIRE) – Lightbridge Corporation (“Lightbridge” or the “Company”) (Nasdaq: LTBR), an advanced nuclear fuel technology company, announced its financial results for the quarter ended March 31, 2026, and provided an update on the Company’s continued progress.

Seth Grae, President & Chief Executive Officer of Lightbridge, commented, "The first quarter of 2026 reflects the depth and pace of Lightbridge's program execution. We received patent allowances from three major jurisdictions—Canada, the United States, and the European Patent Office—expanding the scope of patent protection for Lightbridge Fuel™ across the CANDU fleet, the U.S. domestic light water reactor market, and 39 European contracting states. We also entered into an engineering contract with Stern Laboratories to launch a multi-phase thermal-hydraulics test program to support U.S. regulatory licensing of our fuel for light water reactors. We were selected to serve on the Industry Advisory Board of a $6 million DOE-funded research initiative at Penn State. And our technical team presented proprietary uranium-zirconium alloy research at TMS2026, contributing to the scientific foundation that underpins everything we are building.”

“We believe this is the most promising time for the growth of nuclear power in decades. Record global generation in 2025, sweeping U.S. executive action to accelerate reactor permitting and NRC reform, and landmark procurement commitments from the world's largest technology companies have collectively shifted the industry from a question of 'if' to a question of 'when and how fast.' Lightbridge is building to be the answer to the 'how'—specifically, how the existing global reactor fleet and new-build water-cooled reactors deliver more power and further enhanced safety, with improved economics.”

“Our program is advancing on every front. We have grown to over two dozen in-house engineers across all of our core disciplines, including neutronics, thermal hydraulics, fuel performance, materials, fuel assembly mechanical design, licensing, high-performance computing, and program management, and we continue to add talent. The qualification pathway ahead of us is well-defined. We expect Lightbridge Fuel will enable power uprates of up to 30% or more for new-build water-cooled reactors, meaningfully more than any other approach, while operating approximately 1,000 degrees Celsius cooler. In existing light-water reactors, Lightbridge Fuel is expected to enable power uprates of up to 20% or more (depending on balance-of-plant constraints) and to extend the fuel cycle length. In addition to creating new nuclear generating capacity, the world is seeking greater power from the infrastructure it already has. That is precisely the problem we’ve designed Lightbridge Fuel to solve."

Financial Highlights

Working capital was approximately $215.8 million at March 31, 2026, compared to $201.7 million at December 31, 2025.

Cash Flows Summary

At March 31, 2026, the Company had cash and cash equivalents of $215.7 million, as compared to $201.9 million at December 31, 2025, an increase of $13.8 million, consisting of the following:

·

Cash used in operating activities for the quarter ended March 31, 2026 was $4.8 million, an increase of $1.5 million compared to $3.3 million for the quarter ended March 31, 2025. The increase was primarily due to increased cash expenditures on R&D and general and administrative expenses, partially offset by higher interest income, reflecting increased average cash balances following equity financings.

·

Cash provided by financing activities for the quarter ended March 31, 2026 was $18.6 million, a decrease of $1.6 million compared to $20.2 million for the quarter ended March 31, 2025. The decrease was due to a $1.6 million decrease in net proceeds received from the issuance of common stock under our ATM program and a $0.2 million decrease in net proceeds from the exercise of stock options, partially offset by a $0.2 million decrease in the payment of withholding taxes related to the net share settlement of equity awards.

·

·

General and administrative expenses amounted to $4.3 million for the quarter ended March 31, 2026, compared to $3.5 million for the quarter ended March 31, 2025. The $0.8 million increase was primarily due to a $0.7 million increase in stock-based compensation for employees, contractors, and directors, reflecting several new stock-based awards granted after the prior period end, including performance stock awards, and a $0.1 million
