Basis of Presentation	The accompanying unaudited condensed consolidated financial statements include the accounts of Lightbridge Corporation (Lightbridge or the Company) and the Company’s wholly-owned subsidiary, Thorium Power, Inc. (TPI), a Delaware corporation. TPI is inactive, and all significant intercompany transactions and balances have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (SEC) and do not contain certain information included in the Company’s annual financial statements and notes. These financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, 2025 included in the Company’s Annual Report on Form 10-K filed with the SEC on February 26, 2026. In the opinion of the management of the Company, all adjustments, which are of a normal recurring nature, necessary for a fair statement of the results for the three-month and six-month periods have been made. Results for the interim period presented are not necessarily indicative of the results that might be expected for the entire fiscal year. Certain amounts in the prior year have been reclassified to conform with the current year presentation. These reclassifications had no impact on the previously reported balance sheets, statements of operations, statements of changes in stockholders’ equity, or changes in net cash provided by (used in) operating, investing, or financing activities on the statements of cash flows.
Summary of Significant Accounting Policies	There have been no significant changes in the Company’s accounting policies since December 31, 2025.
Certain Risks and Uncertainties	Based on the Company’s cash position as of June 30, 2026 and current operating plans, management believes the Company has sufficient capital to fund operations for at least 12 months from the issuance of these financial statements. Beyond this period, the Company will need additional funding and/or in-kind support via a combination of strategic alliances, government grants, further offerings of equity securities, or an offering of debt securities in order to support its future research and development (R&D) activities required to further enhance and complete the development and commercialization of its fuel products. There can be no assurance that the Company will be able to successfully continue to conduct its operations if there is a lack of financial resources available in the future to continue its fuel development activities, and a failure to do so would have a material adverse effect on the Company’s future R&D activities, financial position, results of operations, and cash flows. Also, the success of the Company’s operations is subject to numerous other contingencies, some of which are beyond management’s control. These contingencies include general and regional economic conditions, contingent liabilities, potential competition with other nuclear fuel developers, including those entities developing accident tolerant fuels, changes in government regulations, risks related to the R&D of the Company’s fuel, regulatory approval of the Company’s fuel, support for nuclear power, changes in accounting and taxation standards, inability to achieve overall short-term and long-term R&D milestones toward commercialization, including the scale-up of the Company’s nuclear fuel technology and production capabilities, future impairment charges to the Company’s assets, and global or regional catastrophic events. The Company may also be subject to various additional political, economic, and other uncertainties. The Company is engaged in significant R&D activities to advance its nuclear fuel technology at Idaho National Laboratory (INL). For the three and six months ended June 30, 2026, R&D expenses associated with activities conducted at INL accounted for approximately 25% and 24% of the Company’s total R&D expenditure, respectively. For each of the three and six months ended June 30, 2025, R&D expenses associated with activities conducted at INL accounted for approximately 47% of the Company’s total R&D expenditure. Currently, the Company primarily relies on INL for developing, testing, and evaluating its nuclear fuel. Any disruption in access to INL’s resources, including changes in government policies, facility downtime, regulatory constraints, or unforeseen operational challenges could have a material adverse effect on the Company’s current ability to advance its R&D activities.
Recent Accounting Pronouncements	Disaggregation of Income Statement Expenses In November 2024, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (ASU 2024-03), which required disclosure of certain costs and expenses on an interim and annual basis in the notes to the consolidated financial statements. The guidance is effective for annual reporting periods beginning after December 15, 2026 and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The guidance is to be applied either (1) prospectively to financial statements issued for reporting periods after the effective date or (2) retrospectively to any or all prior periods presented in the financial statements. The Company is currently evaluating the potential impact of adopting this new guidance on the consolidated financial statements and related disclosures. The Company has evaluated other recently issued, but not yet effective, accounting standards that have been issued or proposed by the FASB or other standards-setting bodies through the filing date of these unaudited condensed consolidated financial statements and does not believe the future adoption of any such standards will have a material impact on the consolidated financial statements and related disclosures.
