Lightbridge Provides Business Update and Announces Third Quarter 2025 Financial Results

RESTON, Va, November 5, 2025 (GLOBE NEWSWIRE) – Lightbridge Corporation (“Lightbridge” or the “Company”) (Nasdaq: LTBR), an advanced nuclear fuel technology company, announced its financial results for the third quarter and nine months ended September 30, 2025, and provided an update on the Company’s continued progress.

Seth Grae, President & Chief Executive Officer of Lightbridge Corporation, commented, “The nine months of 2025 represented a pivotal time in Lightbridge Fuel's technical development. We have successfully transitioned from design concepts to physical fabrication and testing readiness. Our team achieved critical milestones, including the co-extrusion of an eight-foot demonstration rod using depleted uranium-zirconium alloy, the fabrication of enriched uranium-zirconium alloy samples that match our intended commercial fuel composition, and, most recently, the successful loading of these samples into an experiment assembly that is now ready for insertion into the Advanced Test Reactor. These achievements represent tangible progress toward generating the performance data essential for regulatory licensing.”

“Our presentation of three peer-reviewed papers at TopFuel 2025 further validates our technical approach. These papers demonstrated our fuel's enhanced safety margins during accident scenarios, confirmed the scalability of our manufacturing process through validated modeling, and provided quantitative comparisons showing superior performance versus conventional fuel. This technical validation, combined with the hands-on fabrication work at Idaho National Laboratory, positions us to advance through the critical irradiation testing phase in the Advanced Test Reactor.”

“The current policy environment, highlighted by President Trump’s Executive Orders prioritizing nuclear energy deployment and power uprates for existing reactors, aligns directly with Lightbridge Fuel's capabilities. As we continue to execute on our development roadmap and expand our engineering team, we remain focused on generating the irradiation data necessary to support licensing activities and advance toward commercial deployment. The convergence of our technical progress with supportive market conditions reinforces our confidence in Lightbridge Fuel's potential to enhance both the existing nuclear fleet and future water-cooled reactors."

Financial Highlights

Working capital was approximately $153.1 million at September 30, 2025, compared to $39.9 million at December 31, 2024.

Cash Flows Summary

Cash and cash equivalents were $153.3 million, compared to $40.0 million at December 31, 2024, an increase of $113.3 million for the nine months ended September 30, 2025, consisting of the following:

· Cash used in operating activities for the nine months ended September 30, 2025, was $8.1 million, an increase of $2.4 million compared to $5.7 million for the nine months ended September 30, 2024. The increase was primarily due to elevated spending on research and development (R&D) and general and administrative expenses.

· Cash provided by financing activities for the nine months ended September 30, 2025, was $121.4 million, an increase of $117.7 million compared to $3.7 million for the nine months ended September 30, 2024. This increase was primarily due to an increase in the net proceeds received from the issuance of common stock under our at-the-market facility of $116.7 million and net proceeds from the exercise of stock options of $1.2 million, partially offset by an increase in net share settlement of equity awards for the payment of withholding taxes of $0.2 million.

Balance Sheet Summary

Total assets were $155.1 million and total liabilities were $1.6 million at September 30, 2025.

· Stockholders’ equity was $153.5 million at September 30, 2025, as compared to $40.5 million at December 31, 2024.

Third Quarter 2025 Operations Summary

· General and administrative expenses amounted to $3.2 million for the third quarter ended September 30, 2025, compared to $1.7 million for the third quarter ended September 30, 2024. The increase of $1.5 million was primarily due to higher professional fees, consulting fees, and stock-based compensation.

· Lightbridge’s total R&D expenses amounted to $2.0 million for the third quarter ended September 30, 2025, compared to $1.3 million for the third quarter ended September 30, 2024, an increase of $0.7 million. This increase reflected increased activities related to the development of Lightbridge Fuel, including project labor costs at Idaho National Laboratory, allocated employee compensation and stock-based compensation.

· Total other income was $1.1 million for the third quarter ended September 30, 2025, compared to $0.3 million for the third quarter ended September 30, 2024. Other income consisted of interest income earned from treasury bills and our bank savings account, driven by higher average cash balances.

· Net loss was $4.1 million for the third quarter ended September 30, 2025, compared to $2.7 million for the third quarter ended September 30, 2024.

Nine Months Ended September 30, 2025 - Operations Summary

· General and administrative expenses amounted to $9.2 million for the nine months ended September 30, 2025, compared to $5.7 million for the nine months ended September 30, 2024.

This increase primarily consisted of higher Idaho National Laboratory project labor costs, allocated employee compensation, and stock-based compensation expenses, offset by a decrease in expenses related to the Romania feasibility study and Centrus Energy FEED study which both studies were completed in 2024.

· Total other income was $2.1 million for the nine months ended September 30, 2025, compared to $1.0 million for the nine months ended September 30, 2024. Other income consisted of interest income earned from treasury bills and our bank savings account.
