Lightbridge EXHIBIT 99.1 Lightbridge Provides Business Update and Announces First Half Fiscal 2026 Financial Results RESTON , Va . , August 5 , 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 . "

The increase was primarily due to increased cash expenditures on R&D and G&A expenses, partially offset by higher interest income, reflecting increased average cash balances resulting from proceeds received through the Company's at-the-market (ATM) equity offering program. · Cash provided by financing activities for the six months ended June 30, 2026, was $43.9 million, a decrease of $19.6 million compared to $63.5 million for the six months ended June 30, 2025. This decrease was primarily due to a $18.7 million decrease in net proceeds received from the issuance of common stock under our ATM program. The Company sold an aggregate of 3.8 million shares during the six months ended June 30, 2026, compared to an aggregate of 6.2 million shares during the six months ended June 30, 2025. Second Quarter 2026 Operations Summary · General and administrative expenses amounted to $3.7 million for the quarter ended June 30, 2026, compared to $2.5 million for the quarter ended June 30, 2025. The $1.2 million increase was primarily due to a $0.9 million increase in employee compensation and stock-based compensation for employees, contractors, and directors, reflecting new hires, increased bonuses, and several new stock-based awards, including performance stock awards. Total stock-based compensation included in G&A expenses was $1.0 million and $0.5 million for the three months ended June 30, 2026, and June 30, 2025, respectively. · Lightbridge’s total R&D expenses amounted to $4.0 million for the quarter ended June 30, 2026, compared to $1.6 million for the quarter ended June 30, 2025, an increase of $2.4 million. The increase was primarily due to a $1.4 million increase in employee compensation and stock-based compensation, reflecting an increase in new hires, increased employee bonuses, and several new stock-based awards, including performance stock awards; a $0.4 million increase in R&D project development costs related to cladding, critical heat flux testing, safety analysis, and feasibility studies; and a $0.2 million increase in Idaho National Laboratory (INL) project labor costs, as we entered into additional agreement modifications and new project task statements (PTSs). Total stock-based compensation included in R&D expenses was $0.4 million and $0.2 million for the three months ended June 30, 2026, and 2025, respectively. 2

· During the second quarter of 2026, the Company recorded a total reversal of $0.7 million of previously recognized stock-based compensation related to performance-based awards after the related performance condition was determined to no longer be probable of achievement. Of this amount, $0.5 million reduced general and administrative expense and $0.2 million reduced R&D expense for both the three months and six months ended June 30, 2026. · Total other income was $1.9 million for the quarter ended June 30, 2026, compared to $0.6 million for the quarter ended June 30, 2025.

The $2.0 million increase was primarily due to a $1.5 million increase in employee compensation and stock-based compensation for employees, contractors, and directors, reflecting new hires, increased bonuses, and several new stock-based awards, including performance stock awards, and additional stock-based compensation in the prior period from the accelerated vesting of certain awards. Total stock-based compensation included in G&A expenses was $2.8 million and $1.6 million for the six months ended June 30, 2026, and June 30, 2025, respectively. · Lightbridge’s total R&D expenses amounted to $7.3 million for the six months ended June 30, 2026, compared to $3.3 million for the six months ended June 30, 2025, an increase of $4.0 million.
