NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Nature of Operations, Basis of Presentation, Summary of Significant Accounting Policies and Recent Accounting Pronouncements

Nature of Operations and Basis of Presentation

When used in these notes, the terms “Lightbridge”, “Company,” “we,” “us” or “our” mean Lightbridge Corporation and all entities included in the condensed consolidated financial statements.

The Company was formed on October 6, 2006, when Thorium Power, Ltd., which was incorporated in the state of Nevada on February 2, 1999, merged with Thorium Power, Inc. (TPI), which was incorporated in the state of Delaware on January 8, 1992. On September 29, 2009, the Company changed its name from Thorium Power, Ltd. to Lightbridge Corporation and began its focus on developing and commercializing metallic nuclear fuels. The Company is a nuclear fuel technology company developing its next generation nuclear fuel technology. These condensed consolidated financial statements include the accounts of the Company and the Company’s wholly-owned subsidiaries, TPI, and Lightbridge International Holding LLC, a Delaware limited liability company. These wholly-owned subsidiaries are inactive, and all significant intercompany transactions and balances have been eliminated in consolidation.

The accompanying unaudited condensed consolidated financial statements of Lightbridge Corporation and its subsidiaries have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission, or the SEC, including the instructions to Form 10-Q and Regulation S-X. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America, including a summary of the Company’s significant accounting policies, have been condensed or omitted from these statements pursuant to such rules and regulations and, accordingly, they do not include all the information and footnotes necessary for comprehensive condensed consolidated financial statements and should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2023, included in the Annual Report on Form 10-K for the year ended December 31, 2023 filed with the SEC on March 4, 2024.

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 period 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.

Summary of Significant Accounting Policies* *

Fair Value of Financial Instruments

The Company determines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between unaffiliated market participants at the measurement date.

Accounting Standards Codification (ASC),Fair Value Measurement (ASC 820), establishes a fair value hierarchy that prioritizes the inputs used to measure fair value. Assets and liabilities measured at fair value are categorized based on whether the inputs are observable in the market and the degree that the inputs are observable. The hierarchy gives the highest priority to active markets for identical assets and liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The categorization of financial instruments within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The three levels of the fair value hierarchy are as follows:

Level 1 - Observable inputs such as quoted prices in active markets for identical assets or liabilities;

Level 2 - Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and inputs other than quoted prices that are observable for the asset or liability; and

Level 3 - Unobservable inputs that reflect management’s assumptions.

For disclosure purposes, assets and liabilities are classified in their entirety in the fair value hierarchy level based on the lowest level of input that is significant to the overall fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the placement within the fair value hierarchy levels.

The Company’s financial instruments consist principally of cash and cash equivalents, accounts payable and accrued liabilities. The carrying amounts of accounts payable and accrued liabilities are considered to be a Level 1 measurement, representative of their respective fair values because of the short-term nature of those instruments.

The following table summarizes the valuation of the Company’s cash equivalents (in millions) that fall within the fair value hierarchy at March 31, 2024. There were no cash equivalents at December 31, 2023.

Certain Risks and Uncertainties

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 will be subject to other numerous 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 our nuclear 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, 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.

Recent Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (FASB) issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (ASU 2023-07), which expands on the required disclosure of incremental segment information. The new guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company does not expect this guidance to have a material impact on its consolidated financial statements and related disclosures.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09), which requires companies to annually disclose categories in the effective tax rate reconciliation and additional information about income taxes paid. The new guidance is effective for annual periods beginning after December 15, 2024, with early adoption permitted. The Company expects the new standard to have an immaterial effect on its consolidated financial statements and related disclosures upon adoption.

In August 2020, the FASB issued ASU 2020-06,Debt-Debt with Conversion and Other Options(Subtopic 470-20)* and Derivatives and Hedging- Contracts in Entity’s Own Equity*(Subtopic 815-40), which simplifies the complexity associated with applying U.S. GAAP for certain financial instruments with characteristics of liabilities and equity. This ASU (1) simplifies the accounting for convertible debt instruments and convertible preferred stock by removing the existing guidance in ASC 470-20,Debt: Debt with Conversion and Other Options, that requires entities to account for beneficial conversion features and cash conversion features in equity, separately from the host convertible debt or preferred stock; (2) revises the scope exception from derivative accounting in Subtopic 815-40 for freestanding financial instruments and embedded features that are both indexed to the issuer’s own stock and classified in stockholders’ equity, by removing certain criteria required for equity classification; and (3) revises the guidance in ASC 260,Earnings Per Share, to require entities to calculate diluted earnings per share for convertible instruments by using the if-converted method. ASU 2020-06 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Adoption is either through a modified retrospective method or a full retrospective method of transition. The Company adopted this guidance on January 1, 2024 and the adoption did not have a material impact on its results of operations, financial position, and disclosures because the Company does not have any transactions or instruments to which this standard applies. If in the future, the Company issues new convertible debt, warrants or other instruments, the standard may have a material effect, but it cannot be determined at this time.

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 do not believe the future adoption of any such standards will have a material impact on the Company’s consolidated financial statements and related disclosures.

Note 2. Net Loss Per Share

Basic net loss per share is computed using the weighted-average number of common shares outstanding during the reporting period, except that it does not include unvested common shares subject to repurchase or cancellation. Diluted net loss per share is computed using the weighted-average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise of stock options.

The outstanding securities noted below have been excluded from the computation of diluted weighted shares outstanding for the three months ended March 31, 2024 and 2023, as they would have been anti-dilutive due to the Company’s losses at March 31, 2024 and 2023 and also because the exercise price of certain of these outstanding securities was greater than the average closing price of the Company’s common stock.

Note 3. Prepaid Project Costs and Other Long-term Assets

In 2022, the Company entered into two agreements with Idaho National Laboratory (INL), in collaboration with the United States Department of Energy (DOE), to support the development of Lightbridge Fuel™. At the time of signing, the Company made advanced payments for future project work totaling $0.4 million to Battelle Energy Alliance, LLC (BEA), DOE’s operating contractor for INL. In May 2023, the Company and INL modified the agreements to extend the contract term to May 2029, aligning it with the duration of the irradiation testing and increasing the advanced payments by $0.1 million to $0.5 million. The prepaid project costs were $0.5 million as of March 31, 2024 and December 31, 2023, recorded under Other Assets - Prepaid project costs and other long-term assets.

Note 6. Research and Development Costs

INL Project

In 2022, Lightbridge entered into agreements with BEA, to support the development of Lightbridge Fuel™. These framework agreements use an innovative structure that consists of an “umbrella” SPPA and an “umbrella” CRADA, with an initial duration of seven years. Throughout the duration of these umbrella agreements, all research and development (R&D) work contracted with BEA is through the issuance of PTSs. The initial phase of work under the two agreements will culminate in irradiation testing in the Advanced Test Reactor (ATR) of fuel samples using enriched uranium supplied by the DOE. The initial phase of work aims to generate irradiation performance data for Lightbridge’s delta-phase uranium-zirconium alloy relating to various thermophysical properties. The data, which will be obtained during post-irradiation examination work, will support fuel performance modeling and regulatory licensing efforts for the commercial deployment of Lightbridge Fuel™. For the three months ended March 31, 2024 and 2023, the Company recorded $0.4 million and $0.2 million in R&D expenses associated with INL, respectively.

Romania Feasibility Study

On October 16, 2023, the Company engaged RATEN ICN in Romania to perform an engineering study to assess the compatibility and suitability of Lightbridge Fuel™ for use in CANDU reactors. The total price of approximately $0.2 million is payable in three installments, including an advance payment of $0.1 million and an interim milestone payment and final payment totaling approximately $0.1 million. For the three months ended March 31, 2024, the Company recorded $0.1 million in R&D expenses associated with RATEN ICN.

Centrus Energy FEED Study

On December 5, 2023, the Company entered into an agreement with Centrus Energy to conduct a FEED study to add a dedicated LPFFF at the American Centrifuge Plant in Piketon, Ohio. As of the date hereof, Centrus Energy has completed the initial phase of the FEED study and issued a preliminary report. For the three months ended March 31, 2024, the Company recorded $0.2 million in R&D expenses associated with this FEED study. After reviewing the preliminary report, the Company will decide whether to proceed to the final phase of the FEED study. If the Company decides to move forward with the final phase of the FEED study, the remaining work is expected to be completed in 2024 at an additional fixed price cost of approximately $0.3 million.
