Lightbridge Provides Business Update and Announces Second Quarter 2025 Financial Results

RESTON, Va, August 11, 2025 (GLOBE NEWSWIRE) – Lightbridge Corporation (“Lightbridge” or the “Company”) (Nasdaq: LTBR), an advanced nuclear fuel technology company, announced its financial results for the second quarter ended June 30, 2025, and provided an update on the Company’s continued progress.

Seth Grae, President & Chief Executive Officer of Lightbridge Corporation, commented, “The six months of 2025 marked a period of exceptional progress for Lightbridge as we advanced our nuclear fuel technology. We achieved several critical milestones that position us strongly for the future, including successful co-extrusion demonstration at Idaho National Laboratory in February, completing the final experiment design review in June for our upcoming irradiation testing in the Advanced Test Reactor, and, most recently, successful fabrication of enriched uranium-zirconium alloy coupon samples that will undergo irradiation testing.”

“The political environment has become increasingly favorable for nuclear energy, with President Trump’s nuclear energy Executive Orders in May including a focus on power uprates and federal support for advanced nuclear technologies. Our inclusion in the Russell 2000® and Russell 3000® Indexes validates our progress and enhances our visibility among institutional investors. As we look ahead, we are well-positioned to benefit from the Fission Accelerated Steady-state Testing (FAST) method at Idaho National Laboratory, which we expect will expedite our irradiation testing timeline, and we remain on track to generate the critical performance data needed to support our regulatory licensing efforts and commercial deployment of Lightbridge Fuel,” concluded Mr. Grae.

Larry Goldman, Chief Financial Officer of Lightbridge Corporation, commented, “we ended the second quarter of 2025 with a strong financial position, including $97.9 million in cash and cash equivalents and $97.2 million in working capital as of June 30, 2025. We believe this capital base positions us well to support our fuel development activities and provides us with the financial flexibility to pursue our strategic objectives.”

Financial Highlights

Working capital was $97.2 million at June 30, 2025, compared to $39.9 million at December 31, 2024.

Cash Flows Summary

Cash and cash equivalents were $97.9 million, compared to $40.0 million at December 31, 2024, an increase of $57.9 million for the six months ended June 30, 2025, consisting of the following:

· Cash used in operating activities for the six months ended June 30, 2025, was $5.6 million, an increase of $1.9 million compared to $3.7 million for the six months ended June 30, 2024. The increase was primarily due to increased spending on research and development (R&D) and general and administrative expenses.

· Cash provided by financing activities for the six months ended June 30, 2025, was $63.5 million, an increase of $61.3 million compared to $2.2 million for the six months ended June 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 $60.9 million and net proceeds from the exercise of stock options of $0.6 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 $99.0 million and total liabilities were $1.2 million at June 30, 2025.

· Stockholders’ equity was $97.8 million at June 30, 2025, as compared to $40.5 million at December 31, 2024.

Second Quarter 2025 Operations Summary

· General and administrative expenses amounted to $2.5 million for the second quarter ended June 30, 2025, compared to $1.8 million for the second quarter ended June 30, 2024. The increase of $0.7 million was primarily due to an increase in IT services fees of $0.1 million, an increase in subscription expense of $0.1 million, an increase in professional fees of $0.3 million, and an increase in stock-based compensation of $0.2 million.

· Lightbridge’s total R&D expenses amounted to $1.6 million for the second quarter ended June 30, 2025, compared to $0.9 million for the second quarter ended June 30, 2024, an increase of $0.7 million. This increase was due to the increase in R&D activities related to the development of Lightbridge Fuel. This increase primarily consisted of an increase in Idaho National Laboratories (INL) project labor costs of $0.5 million, an increase in allocated employee compensation and stock-based compensation expenses of $0.1 million and an increase of other R&D expenses of $0.2 million offset by a decrease in R&D expenses related to the Romania feasibility study of $0.1 million, which study was completed in 2024.

· Total other income was $0.6 million for the second quarter ended June 30, 2025, compared to $0.3 million for the second quarter ended June 30, 2024. Other income consisted of interest income earned from the purchase of treasury bills and our bank savings account.

· General and administrative expenses amounted to $6.0 million for the six months ended June 30, 2025, compared to $4.0 million for the six months ended June 30, 2024.
