**Lightbridge Provides Business Update and Announces Third Quarter Fiscal 2026 Financial Results**
RESTON, Va., November 2, 2026 \(GLOBE NEWSWIRE\) – Lightbridge Corporation \(“Lightbridge” or the “Company”\) \(Nasdaq: LTBR\), a nuclear fuel technology company developing Lightbridge Fuel™ to produce more power from existing and new reactors, today reported financial results for the third quarter and nine months ended September 30, 2026, and provided an update on its fuel development activities.
**Third Quarter 2026 and Recent Business Highlights**
|  ·<br><br> |  \*\*Lightbridge was selected for the DOE Nuclear Energy Launch Pad INL program.\*\* In August 2026, Lightbridge was selected to participate in the program, which is administered by DOE's National Reactor Innovation Center \\\(NRIC\\\) at Idaho National Laboratory \\\(INL\\\). Selection provides an accelerated pathway toward DOE authorization for the Company to design, build, and operate the Lightbridge Fuel™ Pilot Factory \\\(Pilot Factory\\\), which the Company also refers to as SHED, at INL to manufacture lead test assemblies \\\(LTAs\\\) of Lightbridge Fuel™ for demonstration in U.S. commercial power reactors. The Company is negotiating the applicable agreements and project scope with NRIC and INL. Authorization to construct and operate the Pilot Factory remains subject to additional DOE/INL agreements, reviews, and authorizations.<br><br> |
|  ·<br><br> |  \*\*Secured loop irradiation testing of clad fuel rodlets in the Advanced Test Reactor \\\(ATR\\\).\*\* In August 2026, the Company entered into Project Task Statement \\\(PTS\\\) No. 2 under its Cooperative Research and Development Agreement \\\(CRADA\\\) with Battelle Energy Alliance, LLC \\\(BEA\\\), the DOE operating contractor for INL. The work covers experimental design, materials, assembly, irradiation, shipment, and disposition of enriched uranium-zirconium fuel rodlets with cladding, in both cylindrical and multi-lobe geometries, irradiated in the ATR loop facility under controlled conditions representative of a commercial reactor.<br><br> |
|  ·<br><br> |  \*\*Post-irradiation examination of the first fuel samples is currently underway.\*\* The first batch of Lightbridge Fuel™ material coupon samples, discharged from the ATR on schedule in May 2026, is currently undergoing post-irradiation examination at INL.<br><br> |
|  ·<br><br> |  \*\*Expanded patent protection in Japan.\*\* In September 2026, the Japan Patent Office issued a notice of allowance for the Company's multi-zone fuel element patent application, with allowed claims covering the fuel element design, a fuel assembly containing it, and an additive manufacturing method for producing it. Japan operates 32 reactors, 15 of which have returned to service, and its national energy plan targets nuclear at approximately 20% of electricity generation by fiscal 2040.<br><br> |

**Management Commentary**
“Selection for the Launch Pad INL program can help to accelerate our commercialization plan,” said Seth Grae, Chairman and Chief Executive Officer of Lightbridge. “Rather than waiting for a commercial fuel factory to be licensed before we could manufacture lead test assemblies, we now have a pathway toward DOE authorization for a dedicated Pilot Factory at INL, and we are negotiating the agreements and project scope with NRIC and INL. In parallel, the loop irradiation agreement we signed in August will enable irradiation testing of the clad Lightbridge Fuel rodlets in the ATR under the conditions similar to those in commercial pressurized water reactors. We believe the loop irradiation will allow us to go from the ATR directly to lead test assemblies in commercial nuclear power plants, rather than first deploying segments of fuel rods and lead test rods in commercial reactors.”
“Our path to acceleration comes at a pivotal moment for the nuclear sector, as major technology companies and utilities increasingly turn to nuclear energy to meet surging baseload power demand from AI, data centers, and industrial electrification. This requires getting substantially more power and higher capacity factors out of the existing nuclear fleet, alongside new builds. Utilities consistently tell us they want three things from an advanced fuel: longer operating cycles between refuelings, power uprates of 10% to 20% from the same plant footprint and operating license, and inherent safety margins that reduce capital and operating costs. Lightbridge Fuel is engineered specifically to meet those requirements.”
**Financial Highlights**
Working capital was approximately $234.2 million at September 30, 2026, compared to approximately $201.7 million at December 31, 2025.
**Cash Flows Summary**
Cash and cash equivalents totaled $236.7 million at September 30, 2026, compared to $201.9 million at December 31, 2025, an increase of $34.8 million. Cash equivalents consisted primarily of U.S. Treasury instruments with maturities of 30 to 90 days.
|  ·<br><br> |  Net cash used in operating activities was $13.2 million for the nine months ended September 30, 2026, compared to $8.1 million for the nine months ended September 30, 2025, reflecting higher research and development \\\(R&D\\\) and general and administrative \\\(G&A\\\) spending, partially offset by higher interest income.<br><br> |
|  ·<br><br> |  Net cash provided by financing activities was $48.1 million for the nine months ended September 30, 2026, compared to $121.4 million for the same period in 2025. The Company sold approximately 4.3 million shares of common stock under its at-the-market \\\(ATM\\\) program during the nine months ended September 30, 2026, for net proceeds of $48.9 million, including 579,685 shares for net proceeds of $4.5 million in the third quarter. As of September 30, 2026, approximately $91.4 million of common stock remained available for sale under the Company's $150 million ATM program.<br><br> |

LIGHTBRIDGE CORPORATION

NOTES TO UNAUDITED CONDENSEDCONSOLIDATED FINANCIAL STATEMENTS</div>

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

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 nine-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 September 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 nine months ended September 30, 2026, R&D expenses associated with activities conducted at INL accounted for approximately % and % of the Company’s total R&D expenditure, respectively. For the three and nine months ended September 30, 2025, R&D expenses associated with activities conducted at INL accounted for approximately % and % of the Company’s total R&D expenditure, respectively. 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 requires 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.

Government Grants

In December 2025, the FASB issued ASU No. 2025-10, Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities (ASU 2025-10). ASU 2025-10 establishes the accounting for a government grant received by a business entity, including guidance for grants related to assets and grants related to income. Government grants received will not be recognized until it is probable that (a) the entity will comply with the conditions attached to the grant and (b) the grant will be received. Grants related to assets will be recognized on the balance sheet as the related costs are incurred, through either the “cost accumulation approach” (reduction to the asset’s cost basis and subsequent recognition through reduced depreciation expense) or the “deferred income approach” (deferred and subsequently recognized in earnings). Grants related to income and grants related to an asset under which the deferred income approach is elected will be recognized in earnings on a systematic and rational basis over the periods in which the entity recognizes the costs for which the grant is intended to compensate and presented as either other income or as a deduction from the related expenses. The guidance is effective for annual and interim reporting periods beginning after December 15, 2028. Early adoption is permitted. The guidance is to be applied on either (1) a modified prospective approach, which entails prospective application for new grants and incomplete grants as of the effective date, (2) a modified retrospective approach with a cumulative-effect adjustment to retained earnings for both government grants entered into on or after the beginning of the earliest period presented and government grants not completed as of the beginning of the earliest period presented, or (3) a retrospective approach for all government grants with a cumulative-effect adjustment through retained earnings. The Company is currently evaluating the potential impact of adopting this new guidance on the consolidated financial statements and related disclosures, in connection with the Company’s acceptance into the Department of Energy’s Nuclear Energy Launch Pad INL program, as described further below under Note 5. Commitments and Contingencies.

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.

Note 2. Fair Value Measurements

The Company’s financial instruments consist principally of cash and cash equivalents, accounts payable, and accrued liabilities. The carrying amounts of cash, accounts payable, and accrued liabilities are considered to be Level 1 measurements, because of the short-term nature of those instruments. At September 30, 2026 and December 31, 2025, the Company held cash balances totaling $ million and $ million, respectively, in excess of the federally insured limits of $. The Company deemed this credit risk not to be significant as cash in excess of the federally insured limits was held by two prominent financial institutions during these periods.

Cash equivalents are primarily composed of U.S. Treasury instruments having maturity dates of 30-90 days. At September 30, 2026 and December 31, 2025, the Company held U.S. Treasury bills with an amortized cost basis of $ million and $ million, respectively, on its balance sheet.

The Company reviewed its U.S. Treasury instruments held at the end of each reporting period to determine whether the securities were of the most recent issuance of that security with the same maturity (referred to as “on-the-run,” which is the most liquid version of the maturity band). If a U.S. Treasury instrument held at the end of the reporting period is from the most recent issuance, it is classified as Level 1. Otherwise, it is referred to as “off-the-run” and is classified as Level 2.

The following table summarizes the valuation of the Company’s cash equivalents within the fair value hierarchy (in millions) at September 30, 2026:

The following table summarizes the valuation of the Company’s cash equivalents within the fair value hierarchy (in millions) at December 31, 2025:

Note 3. Prepaids and Other Assets

Prepaid expenses and other current assets consist of the following (in millions):

Prepaid project costs and other long-term assets consist of the following (in millions):

In 2022, the Company entered into two agreements with Battelle Energy Alliance, LLC (BEA), the U.S. Department of Energy’s (DOE) operating contractor for INL, to support the development of Lightbridge Fuel™. Under these agreements, as modified from time to time, the Company may make advance payments to support specific contracted project work. These advance payments are recorded as prepaid assets on the balance sheet and classified as short-term or long-term, depending on the associated performance period remaining. As of September 30, 2026 and December 31, 2025, we had total short-term and long-term advance payments to BEA of $ million and $ million, respectively.

Note 4. Accounts Payable and Accrued Liabilities

Accounts payable and accrued liabilities consist of the following (in millions):

Note 5. Commitments and Contingencies

The Company has entered into initial project task statements (PTSs) with BEA related to R&D work being conducted under the Strategic Partnership Project Agreement (SPPA) and Cooperative Research and Development Agreement (CRADA) at INL. Performance of work under these agreements may be terminated at any time by either party, without any liability, after the effective date of termination, upon giving a thirty-day written notice under the SPPA and a sixty-day written notice under the CRADA. In the event of termination, the Company shall be responsible for BEA’s costs (including the closeout costs) through the effective date of termination, but in no event shall the Company’s cost responsibility exceed the total estimated cost stated in each PTS and any subsequent modification to the PTS.

As of September 30, 2026, the aggregate funding commitment remaining under the Company’s PTSs with BEA, if and when incurred, would not exceed $ million over the anticipated performance period. Actual expenditures may differ from this amount based on the scope and timing of work performed through the issuance of additional PTSs to BEA.

In August 2026, the Company was selected to participate in the Nuclear Energy Launch Pad INL program, administered by the DOE’s National Reactor Innovation Center (NRIC) at INL. In connection with our participation in the Nuclear Energy Launch Pad INL program, we intend to develop a Lightbridge Fuel™ Pilot Factory (Pilot Factory) at INL. The authorization to construct or operate the Pilot Factory remains subject to additional DOE/INL agreements, reviews, authorizations and other prerequisites before construction can start. As of September 30, 2026, the Company has not yet entered into any material binding commitments for the construction of the Pilot Factory. Related costs incurred through September 30, 2026 have not been material.

Note 6. Stockholders’ Equity

At September 30, 2026 and December 31, 2025, the Company had and common shares outstanding, respectively (including outstanding restricted stock awards (RSAs) and performance-based restricted stock awards (PSAs) totaling shares and shares, respectively). No preferred shares were outstanding at September 30, 2026 and December 31, 2025.

The Company has entered into sales agreements with agents pursuant to which the Company may issue and sell shares of its common stock in “at-the-market” (ATM) equity offerings as defined in Rule 415 promulgated under the Securities Act of 1933, as amended. The Company records its ATM sales on a settlement date basis. The sales commissions and expenses related to each ATM program are considered direct and incremental costs and are charged against “Additional paid-in capital” on the consolidated balance sheets in the period in which the corresponding shares are issued and sold.

During the three months ended September 30, 2026, the Company sold an aggregate of shares under its sales agreement with Jefferies, LLC (Jefferies), resulting in aggregate net proceeds of $ million.

The total stock-based compensation expense recorded in R&D and general and administrative expenses in the Company’s consolidated statements of operations for the three and nine months ended September 30, 2026 and 2025 is as follows (in millions):

2020 Omnibus Incentive Plan

The Company maintains the 2020 Omnibus Incentive Plan (the 2020 Plan), under which eligible participants may be awarded various types of stock-based compensation, including stock options, restricted stock awards, and other stock-based and cash-based awards.

In August 2026, the Board approved equity awards designed to support the Company’s lead test assembly (LTA) production strategy and retain and attract key personnel involved in the development and commercialization of Lightbridge Fuel™ (the August 2026 Grant Pool). The August 2026 Grant Pool included an aggregate of service-based RSAs to current and future employees, contractors, and directors under the 2020 Plan. These RSAs vest in six equal installments on each of the first six semi-annual anniversaries of the Board approval date, prorated based on the start date for new hires.

The August 2026 Grant Pool also included an aggregate of PSAs to current and future employees, contractors, and directors, contingent upon approval by the Company’s stockholders of an increase in the number of shares authorized under the 2020 Plan to accommodate these awards. If stockholder approval is not obtained, the PSAs will not be granted and will not be deducted from the shares reserved for issuance under the 2020 Plan. These PSAs vest based on the attainment of three specific R&D fuel program milestones related to the construction and commissioning of a pilot-scale fuel fabrication facility and the production of at least one complete LTA and are subject to each participant having completed at least twelve months of continuous service with the Company as of the milestone achievement date. Each milestone applies to a separate portion of the PSAs, and vesting of the PSAs occurs in unequal tranches depending on which milestone is certified. The performance periods for achieving these milestones extend from the grant dates to as early as December 31, 2029 and as late as December 31, 2034.

As of September 30, 2026, there were shares of common stock reserved and available for issuance under the 2020 Plan, excluding the August 2026 Grant Pool PSAs which have not yet been approved by the Company’s stockholders.

Restricted Stock Awards

The following summarizes the Company’s RSA activity (limited to RSAs with no performance-based conditions) for the nine months ended September 30, 2026:

During the nine months ended September 30, 2026, the Company granted RSAs to the independent members of its Board of Directors (the Board), of which RSAs vest in four equal installments at the end of each calendar quarter of 2026 and RSAs vest in six equal semi-annual installments over a three-year period from the grant date.

During the nine months ended September 30, 2026, the Company granted RSAs to external consultants. These awards vest in equal quarterly installments over a one-year period from the grant date.

During the nine months ended September 30, 2026, the Company also granted RSAs to employees and consultants vesting in equal semi-annual or annual installments over a three-year period starting from the grant date.

The weighted-average grant-date fair value per share of RSAs granted for the nine months ended September 30, 2026 and 2025 was $ and $, respectively. During the nine months ended September 30, 2026, a total of RSAs vested, with an aggregate fair value of $ million, and the Company withheld shares to satisfy tax obligations, resulting in net shares issued. During the nine months ended September 30, 2025, RSAs with an aggregate fair value of $ million vested, and the Company withheld shares to satisfy tax obligations, resulting in net shares issued.

During the three months ended September 30, 2026 and 2025, the Company recognized approximately $ million and $ million in total stock-based compensation expense from RSAs, respectively. During the nine months ended September 30, 2026 and 2025, the Company recognized approximately $ million and $ million in total stock-based compensation expense from RSAs, respectively. The stock-based compensation expense recorded during the nine months ended September 30, 2025 included approximately $ million of stock-based compensation expense related to accelerated vesting in connection with a separation agreement with a former employee. As of September 30, 2026, total unrecognized compensation cost related to RSAs was $ million, which is expected to be recognized over a remaining weighted-average vesting period of years.

Performance-based Restricted Stock Awards

The following summarizes the Company’s PSA activity for the nine months ended September 30, 2026:

The weighted-average grant-date fair value per share of PSAs granted for the nine months ended September 30, 2026 and 2025 was $ and $, respectively. During the nine months ended September 30, 2026, a total of PSAs vested, with an aggregate fair value of $ million, and the Company withheld shares to satisfy tax obligations, resulting in net shares issued.

For the three months ended September 30, 2026 and 2025, the Company recognized approximately $ million and $ million in stock-based compensation expense from PSAs, respectively. For the nine months ended September 30, 2026 and 2025, the Company recognized approximately $ million and $ million in stock-based compensation expense from PSAs, respectively. As of September 30, 2026, total unrecognized compensation cost related to PSAs was $ million, which is expected to be recognized over a remaining weighted-average vesting period of years.

As of September 30, 2026, the Company had PSAs outstanding with three specific R&D fuel program milestones and one specific financial milestone (the Tranche-based PSAs). During the nine months ended September 30, 2026, shares of Tranche-based PSAs were granted to new employees. Each milestone applies only to a separate portion of the Tranche-based PSAs. Vesting of the Tranche-based PSAs occurs in unequal tranches depending on which milestone is certified and is subject to the grantee having completed at least twelve months of continuous service with the Company as of the milestone achievement date. The performance period for achieving these milestones extends from the grant date to December 31, 2028. As of September 30, 2026, management concluded that only one performance milestone was probable of achievement.

During the second quarter of 2026, management concluded a performance milestone under the Tranche-based PSAs previously deemed probable was no longer probable based on revised expectations during the quarter, due to changes in the Company’s planned fuel development and manufacturing activities associated with producing LTAs at the planned Pilot Factory. As a result, the Company reversed $ million of previously recorded stock-based compensation related to this performance milestone during the three months ended June 30, 2026. During the three months ended September 30, 2026 and 2025, the Company recognized net stock-based compensation expense of $ million and $ million, respectively, related to the Tranche-based PSAs. During the nine months ended September 30, 2026 and 2025, the Company recognized net stock-based compensation expense of $ million and $ million, respectively, related to the Tranche-based PSAs. The $ million recognized for the nine months ended September 30, 2026 was net of the reversal of $ million of previously recognized stock-based compensation related to the aforementioned performance milestone.

As of September 30, 2026, the Company had PSAs outstanding, which were granted in April 2025 (the April 2025 PSAs) with a performance condition requiring the successful insertion of the Company’s fuel material coupon samples into the Advanced Test Reactor at INL by December 31, 2026. This condition was satisfied in November 2025 and satisfaction was subsequently certified by the Compensation Committee. The April 2025 PSAs are also subject to the participant’s continuous service over a three-year period from the grant date. During the three months ended September 30, 2026 and 2025, the Company recognized $ million and $ million in stock-based compensation expense related to the April 2025 PSAs. During the nine months ended September 30, 2026 and 2025, the Company recognized $ million and $ million in stock-based compensation expense related to the April 2025 PSAs.

Note 8. 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, such as the Company’s RSAs and PSAs. 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 and unvested RSAs and PSAs.

The outstanding securities in the table below have been excluded from the computation of diluted weighted shares outstanding for the three and nine months ended September 30, 2026 and 2025, as they would have been anti-dilutive due to the Company’s losses for the three and nine months ended September 30, 2026 and 2025.

Note 9. Segment Reporting

The Company has one reportable business segment: nuclear fuel technology. This segment consists of the research and development and commercialization of its nuclear fuel. The Company’s chief operating decision maker (CODM) is the chief executive officer. The CODM assesses performance for the segment and allocates resources based on net loss as reported on the consolidated statement of operations. The CODM also reviews total assets as reported on the consolidated balance sheet to assess capital deployment and liquidity available to support the Company's commercialization strategy. The measure of segment assets is reported on the consolidated balance sheet as total assets.

The table below summarizes the significant expense categories regularly provided to the CODM for the three and nine months ended September 30, 2026 and 2025 (in millions):

Overview of Our Business and Recent Developments Regarding Lightbridge Fuel™

When used in this Quarterly Report on Form 10-Q, the terms “Lightbridge,” the “Company,” “we,” “our,” and “us” refer to Lightbridge Corporation together with its wholly-owned subsidiary, Thorium Power Inc.

Our Business

At Lightbridge, we are developing advanced metallic nuclear fuel for existing and new water-cooled reactors designed to improve the economics and safety of existing and new nuclear power plants and enhance proliferation resistance of spent nuclear fuel while supplying clean energy to the electric grid or to “behind the meter” customers for electric power, including data centers. We believe our metallic fuel could offer significant economic and safety benefits over traditional nuclear fuel, primarily because of the superior heat transfer properties and the resulting lower operating temperature of our all-metal fuel.

We believe our metallic fuel can be used in different types of water-cooled commercial power reactors, such as pressurized water reactors, boiling-water reactors, Russian-designed water-cooled commercial power reactors, Canada Deuterium Uranium heavy water reactors, water-cooled small modular reactors, and water-cooled research reactors. We have obtained patent validation in key countries that we believe would have a commercial market for our fuel and will continue to seek patent validation in countries that either currently operate or are expected to build and operate a large number of nuclear power reactors compatible with our fuel technology.

Commercialization Pathway and Key Development Milestones

The Company believes long-term industry trends continue to support investment in advanced nuclear technologies. Growing demand for reliable electricity, including demand associated with artificial intelligence computing, hyperscale data centers, electrification, advanced manufacturing, and energy security initiatives, has significantly increased interest in expanding nuclear generation and improving the performance of existing reactors. Advances in reactor technology, combined with growing corporate and governmental support for nuclear energy, can position nuclear power as a cornerstone of future energy strategies for data-intensive industries, which recent evidence suggests may be willing to pay a premium for reliable, clean, and sustainable baseload electricity. The Company believes these trends may increase the long-term market opportunities for advanced nuclear fuel technologies designed to improve reactor economics, increase power output, and enhance operational flexibility. Accordingly, the Company's current research, engineering, manufacturing planning, and strategic collaborations are focused on advancing the technical and commercial readiness of Lightbridge Fuel™ to address these long-term market opportunities.

The long-term milestones marking progress towards development and commercialization of nuclear fuel assemblies include, among other matters:

There are inherent uncertainties in the cost and outcomes of the many steps needed for successful deployment of Lightbridge Fuel™ in commercial nuclear reactors, which makes it difficult to accurately predict the timing of the commercialization of our nuclear fuel technology. Our ultimate commercial model remains under evaluation and may evolve as our fuel development progresses, regulatory pathways are further clarified, and commercial partnerships are further established. See Part I, Item 1A. Risk Factors—“Risks Related to Our Business and to the Commercialization of Lightbridge Fuel™” in our Annual Report on Form 10-K for the year ended December 31, 2025.

Development of the Lightbridge Fuel™ Pilot Factory

In August 2026, the Company was selected to participate in the Nuclear Energy Launch Pad INL program, administered by the U.S. Department of Energy’s (DOE) National Reactor Innovation Center (NRIC) at Idaho National Laboratory (INL). Selection provides an accelerated pathway toward DOE authorization for the Company to design, build, and operate a Lightbridge Fuel™ pilot factory at INL to manufacture LTAs of Lightbridge Fuel™ for demonstration in U.S. commercial power reactors. By establishing a dedicated manufacturing facility under DOE authorization, the Company expects to shorten the timeline for producing LTAs for operation in commercial U.S. reactors.

In connection with our participation in the Nuclear Energy Launch Pad INL program, we intend to develop a Lightbridge Fuel™ Pilot Factory (Pilot Factory), formerly referred to as the Special High-assay low-enriched uranium (HALEU) Extrusion Demonstration (SHED) Facility, at INL. Based on preliminary estimates, we currently expect the development and construction costs of the Pilot Factory to require approximately $140 million of expenditures that will be phased over approximately the next five-year development and construction period. The timing of this spending will be dependent on the completion of engineering, DOE/INL approvals, procurement decisions, construction milestones and other project requirements. Actual costs could be materially higher depending on the final design, scope, procurement requirements, construction conditions, regulatory requirements and other factors. These estimates remain preliminary and are subject to change as engineering, design, procurement and construction planning advance. The authorization to construct and operate the Pilot Factory remains subject to additional DOE/INL agreements, reviews, authorizations and other prerequisites before construction can start. There can be no assurance that such regulatory approvals will be obtained or obtained on the timeline currently anticipated by the Company. As of September 30, 2026, we had not entered into any material binding commitments for the construction of the Pilot Factory. We are currently working with NRIC/INL to negotiate the applicable agreements and project scope.

We plan to design the Pilot Factory as a multi-purpose fuel manufacturing and R&D platform. The Company currently expects that the facility and certain of its major production equipment will be capable of supporting the manufacture and development of metallic nuclear fuel components for multiple water-cooled reactor applications and fuel configurations.

The Pilot Factory will have a dedicated research and development workshop. We expect to design this R&D workshop as a flexible, multi-purpose research environment capable of supporting multiple current and future R&D projects. Research activities in the R&D workshop may include additive manufacturing and other advanced manufacturing techniques for producing nuclear fuel and reactor parts; development and evaluation of different fuel designs, compositions, geometries and configurations for different reactor types; and fuel-manufacturing process development and optimization for the future commercial Lightbridge Fuel™ Factory. The completion, modification or discontinuation of any individual R&D project is not expected, by itself, to eliminate the anticipated future utility of the underlying facility or shared equipment for other company activities. The ultimate technical feasibility, regulatory acceptance, economic viability, and commercial success of technologies developed through these activities remain subject to significant uncertainties.

In addition to these estimated facility development and construction costs, we expect to incur increased personnel and operating expenses as we hire employees and build the capabilities necessary to support the Pilot Factory and our broader fuel-development activities. The timing and amount of these expenditures will depend on the progress and scope of the project and other factors and cannot be reasonably estimated at this time.

The DOE’s authorization to construct and operate the Pilot Factory is separate from, and does not constitute, any approval or commitment by the DOE to provide funding for the Pilot Factory. We currently expect to fund these expenditures from our existing cash and financial resources and, as appropriate, additional capital raised through our ATM program or other financing activities. Although we believe our existing financial resources are sufficient to fund our currently anticipated near-term requirements, the development of the Pilot Factory and advancement of Lightbridge Fuel™ toward commercialization will require substantial expenditures over several years. See Part II, Item 1A. Risk Factors—"The development and construction of the Pilot Factory will require substantial capital expenditures, and our current estimates of the cost, timing and scope of the project may change materially” in this Quarterly Report on Form 10-Q.

DOE authorization to design, construct and operate the Pilot Factory does not constitute authorization for Lightbridge Fuel™ LTAs to be loaded, irradiated or otherwise used in a U.S. commercial nuclear power reactor. Any such use would remain subject to applicable U.S. Nuclear Regulatory Commission licensing, review and approval requirements, as well as any required approvals or actions by the host utility. There can be no assurance that such regulatory approvals or acceptance of LTAs by the host utility will be obtained, or obtained on the timeline currently anticipated by the Company.

Uranium Supply Dependency

Development of the Pilot Factory and the Company’s planned future fabrication of lead test assemblies will require access to qualified sources of uranium feedstock, including HALEU, where applicable, and uranium metal that meet applicable technical, regulatory and program requirements. The Company is evaluating potential supply sources, alternative supply arrangements and related infrastructure requirements to support these activities. The availability and timing of qualified HALEU and uranium metal, the need to qualify additional suppliers or processes, changes in pricing, or the need for additional deconversion, metallization or other supporting infrastructure could affect the timing and cost of the Pilot Factory program and the Company’s future capital requirements. The Company continues to assess these supply-chain requirements as the design, development and implementation of the Pilot Factory program progresses. See Part I, Item 1A. Risk Factors—“Risks Related to Our Business and to the Commercialization of Lightbridge Fuel™—Dependence on the Future Availability of Cost-Competitive Metallic HALEU and Commercial-Scale Fuel Fabrication Infrastructure” in our Annual Report on Form 10-K for the year ended December 31, 2025.

Development of Future Lightbridge Commercial Fuel Factory

The Company is also evaluating a potential site location and developing a conceptual design for a future commercial Lightbridge Fuel™ Factory (Fuel Factory), formerly referred to as the Lightbridge Expandable Fuel Facility (LEFF), to support the possible future fabrication of Lightbridge Fuel™ at commercial quantities for use in commercial reactors. In connection with these efforts, the Company may decide, from time to time, to apply to programs available through various governmental agencies that offer funding, regulatory flexibility, or other support related to the advancement of its nuclear fuel technology. Such programs may require significant capital investment and could materially increase research and development activities, capital expenditures, manufacturing capabilities and staffing over the next several years.

While the scope, timing, and cost of constructing such a facility cannot be reasonably estimated at this time, the Company expects that the capital required to design, license, construct and commission the Fuel Factory would be substantial and would significantly exceed the capital required for the Pilot Factory. The Fuel Factory is expected to involve commercial-scale nuclear fuel manufacturing infrastructure, and its ultimate cost could be materially affected by facility size, production capacity, site-specific requirements, nuclear licensing and regulatory requirements, security and safeguards, equipment specifications, supply-chain conditions, construction costs and other factors. The timing, amount, and sources of any related financing activities will depend on a number of factors, including the progress of the Company’s development programs, regulatory considerations, market conditions, and the availability of strategic partnerships or other funding sources. There can be no assurance that the Company will be able to obtain such financing on acceptable terms, or at all, nor can there be any assurance that the Company will pursue the construction of the Fuel Factory.

Recent Developments Regarding Lightbridge Fuel™

Reconstitution of the Nuclear Utility Fuel Advisory Board

In June 2026, the Company launched a reconstituted Nuclear Utility Fuel Advisory Board, which is intended to provide the Company with input directly from utility industry representatives regarding fuel development priorities, licensing considerations, deployment strategies, operational requirements, and commercialization planning. Interest from utilities is primarily based on the potential safety and economic benefits of Lightbridge Fuel™. See Part I, Item 1A. Risk Factors—“Risks Related to Our Business and to the Commercialization of Lightbridge Fuel™” in our Annual Report on Form 10-K for the year ended December 31, 2025.

The advisory board serves in an advisory capacity only and does not constitute a commitment by any participant to purchase, license, deploy, or otherwise utilize the Company's fuel technology.

Updates to Idaho National Laboratory Agreements

In 2022, the Company entered into agreements with Battelle Energy Alliance, LLC (BEA), the DOE operating contractor for INL, to support the development of Lightbridge Fuel™. The framework agreements consist of an “umbrella” Strategic Partnership Project Agreement (SPPA) and an “umbrella” Cooperative Research and Development Agreement (CRADA), each with BEA. The Company continues to perform work under its SPPA and CRADA with BEA, as previously described in the Company's Annual Report on Form 10-K for the year ended December 31, 2025. The Company periodically updates project scopes, schedules and cost estimates using a rolling wave planning approach for project management purposes on the released scopes of work. It is an iterative planning technique in which the work to be accomplished in the near term is planned in detail, while work further in the future is planned at a higher level. As such, periodic revisions to the scope and/or cost estimates are anticipated.

Irradiation Testing – INL Loop Test Facility

In August 2026, the Company entered into CRADA Project Task Statement (PTS) No. 2 with BEA to support activities associated with irradiation testing necessary to validate the performance of Lightbridge Fuel™ by testing enriched uranium and zirconium fuel rodlets with cladding in cylindrical and multi-lobe geometry within the loop testing facility of the Advanced Test Reactor. Loop irradiation testing allows fuel samples to be irradiated under controlled reactor operating conditions in order to collect data necessary to validate fuel behavior. Successful irradiation testing is expected to provide key performance data supporting the Company's long-term commercialization strategy and ongoing engagement with current and prospective nuclear utility and strategic partners.

The scope of work under the PTS includes experiment design, provision of materials, assembly, irradiation and shipment, and disposition of materials. The work builds upon prior technical accomplishments under earlier PTSs, including fuel fabrication process development, and represents a significant step toward qualifying Lightbridge Fuel™ for commercial deployment in existing light water reactors. The PTS has an estimated total cost of approximately $9.0 million of cash funding and approximately $1.9 million of in-kind contributions to be provided by the Company, consisting primarily of engineering, technical, and project management support, and a period of performance of approximately 60 months. Costs are incurred on a reimbursable basis, with advance and monthly funding provided by the Company. The Company is not obligated to continue work that would cause it to exceed the estimated cost.

Other Updates to the SPPA and CRADA

In June 2026, the Company entered into Modification No. 5 to CRADA Project Task Statement (PTS) No.1 with BEA to increase the total estimated reimbursable cost by approximately $1.1 million, bringing the total estimated cost for the work to be performed under CRADA PTS No.1 to $5.4 million.

In April 2026, the Company entered into SPPA PTS No. 6 to support the development of coextruded fuel rod components for future loop irradiation testing in the Advanced Test Reactor (ATR) and transient testing in the Transient Reactor Test Facility. This program builds on prior INL fabrication work and is intended to further refine manufacturing processes and materials necessary to produce fuel rods and rodlets in their final cross-sectional configurations.

Initial process development activities will be conducted using depleted uranium, with the expectation that, upon successful demonstration, these processes may be applied to enriched uranium to produce fuel rod segments for irradiation experiments at test reactors, including the ATR. The program is expected to help bridge the transition from earlier-stage fabrication development and initial coupon fuel material samples currently undergoing irradiation testing in the ATR to the production of irradiation rod segment test specimens. The scope of work includes enhancements to fabrication processes and equipment, development and testing of key materials (including central displacer alloys and cladding behavior), and validation of coextrusion techniques for both cylindrical and multi-lobe fuel designs. The program also includes preparation of fuel rod segment specimens, including those with controlled defects, to support non-destructive evaluation calibration and irradiation testing. The total estimated cost of SPPA PTS No.6 is approximately $4.6 million over an expected performance period of 36 months. Costs are incurred on a reimbursable basis, with advance and monthly funding provided by the Company. The Company is not obligated to continue work beyond the estimated cost without additional authorization. This effort represents a key step in the Company’s ongoing fuel qualification strategy, supporting the advancement from process development toward irradiation testing and future commercialization activities.

In March 2026, the Company entered into Modification No. 4 to CRADA PTS No. 1 with BEA to extend the performance period end date through September 2032 and increase advanced funding by $0.3 million, with no increase to the total estimated reimbursable cost.

Total Cumulative Estimated Costs

As of September 30, 2026, the Company expects to pay an aggregate $34.2 million to BEA under the CRADA and the SPPA on a cost reimbursable basis over the performance periods. As of September 30, 2026, a cumulative total of $8.3 million has been expensed and the aggregate funding commitment remaining under these agreements is $25.9 million. These obligations are generally cancellable with 30-60 days’ notice and, therefore, are not considered firm commitments, and are not expensed until incurred. Actual expenditures may differ from this amount based on the scope and timing of work performed through the issuance of additional PTSs to BEA.

Master Services Agreement with Amentum Technology Inc.

In December 2025, the Company entered into a Master Services Agreement (MSA) with Amentum Technology Inc. (Amentum) relating to the performance of activities by Amentum in support of various activities as the Company and Amentum may agree from time to time. In June 2026, the Company entered into a new task order with Amentum to conduct feasibility and site selection studies and develop a conceptual design for a standalone Fuel Factory, with completion of deliverables expected in early 2027. The Company expects to incur approximately $2.4 million of expenses under this task order.

Critical Accounting Estimates

For a discussion of the accounting judgments and estimates that we have identified as critical in the preparation of our financial statements, please see Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—“Critical Accounting Estimates” in our Annual Report on Form 10-K for the year ended December 31, 2025. There have been no significant changes in our critical accounting policies and estimates during the nine months ended September 30, 2026.

Operations Review

During the first three quarters of 2026, the Company continued to accelerate the development of Lightbridge Fuel™. Operating expenses increased for the three and nine months ended September 30, 2026 primarily as a result of the Company's continued investment in engineering, fuel development, manufacturing readiness activities, project development, and organizational infrastructure supporting the long-term development of Lightbridge Fuel™. The Company generated increased interest income from its significantly higher cash balances invested primarily in U.S. Treasury securities.

Financial information is included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

Condensed Consolidated Results of Operations - Three Months Ended September 30, 2026 and 2025

The following table presents our operating results and the change in amounts for the periods indicated (in millions):

Operating Expenses

General and Administrative

General and administrative (G&A) expenses consist primarily of compensation and related costs for finance personnel, including stock-based compensation, and fees for professional and consulting services. Professional services are principally comprised of legal, audit, strategic advisory services, and outsourced services such as human resources and information technology.

G&A expenses increased by $1.8 million for the three months ended September 30, 2026, as compared to the three months ended September 30, 2025. The increase was due to:

Total stock-based compensation included in G&A expenses was $1.6 million and $1.1 million for the three months ended September 30, 2026 and 2025, respectively.

Research and Development

R&D expenses consist primarily of costs associated with our CRADA and SPPA agreements with BEA, IT expenses, employee compensation and related fringe benefits, including stock-based compensation, and other R&D costs for the development of our Lightbridge Fuel™.

The following table presents our total R&D expenses for the three months ended September 30, 2026 and 2025 (in millions):

R&D expenses increased by $3.3 million for the three months ended September 30, 2026, as compared to the three months ended September 30, 2025. The increase was due to:

Total stock-based compensation included in R&D expenses was $0.8 million and $0.5 million for the three months ended September 30, 2026 and 2025, respectively.

Interest Income

There was an increase in interest income of $0.9 million due to higher cash balances, which resulted in an increase in interest income earned from the purchase of treasury bills and from our bank savings account for the three months ended September 30, 2026, as compared to the three months ended September 30, 2025.

Condensed Consolidated Results of Operations - Nine Months Ended September 30, 2026 and 2025

The following table presents our operating results and the change in amounts for the periods indicated (in millions):

Operating Expenses

General and Administrative

G&A expenses increased by $3.8 million for the nine months ended September 30, 2026, as compared to the nine months ended September 30, 2025. The increase was due to:

Total stock-based compensation included in G&A expenses was $4.4 million and $2.7 million for the nine months ended September 30, 2026 and 2025, respectively. The amount for the nine months ended September 30, 2026 was net of the reversal of $0.5 million of previously recognized stock-based compensation related to a performance milestone under our Tranche-based PSAs that is no longer deemed probable of achievement. The amount for the nine months ended September 30, 2025 includes $0.5 million of stock-based compensation expense related to accelerated vesting of RSAs in connection with a separation agreement with a former employee.

As our R&D and manufacturing-readiness activities expand, we expect to continue increasing our employee base and administrative infrastructure to support these activities. Accordingly, we expect employee compensation, recruiting, professional services and other G&A expenses to increase over time, although the amount and timing of these increases will depend on the pace and scope of our development programs.

Research and Development

The following table presents our total R&D expenses for the nine months ended September 30, 2026 and 2025 (in millions):

R&D expenses increased by $7.3 million for the nine months ended September 30, 2026, as compared to the nine months ended September 30, 2025. The increase was due to:

Total stock-based compensation included in R&D expenses was $1.9 million and $0.9 million for the nine months ended September 30, 2026 and 2025, respectively. The amount for the nine months ended September 30, 2026 was net of the reversal of $0.2 million of previously recognized stock-based compensation related to a performance milestone under our Tranche-based PSAs that is no longer deemed probable of achievement.

We expect to significantly increase our R&D expenditures as we advance fuel fabrication development, irradiation testing programs, and our collaboration with DOE and INL, and as we perform engineering, site evaluation and other development activities related to the Pilot Factory. We also expect to hire additional engineering and technical personnel to support these initiatives. The amount and timing of future expenditures will depend on the scope and progress of these activities, and certain costs incurred in connection with future facility construction may qualify for capitalization rather than being recorded as expense.

Due to the nature of our R&D expenditures, future costs and schedule estimates are inherently uncertain and can vary significantly as new information and the outcomes of these R&D activities become known. Our future business operations are dependent on budgetary constraints due primarily to market conditions and the uncertainty of future liquidity and capital resources available to us to conduct our future R&D activities.

Interest Income

There was an increase in interest income of $3.1 million due to higher cash balances, which resulted in an increase in interest income earned from the purchase of treasury bills and from our bank savings account for the nine months ended September 30, 2026, as compared to the nine months ended September 30, 2025.

Liquidity, Capital Resources and Financial Position

Overview – Funding Requirements

We assess our liquidity based on our ability to fund the cash requirements of our ongoing R&D activities, G&A expenses, contractual obligations, and other operating needs. Based on our current projected operating expenses, available cash resources, and our current cash forecast, including the presently anticipated near-term Pilot Factory spending, we believe that we have sufficient liquidity to fund our operations and meet our anticipated cash requirements for at least the next 12 months from the date of this filing. Our longer-term liquidity will depend on our ability to obtain additional financing. Our existing capital resources are not sufficient to fund all of our long-term operations, R&D activities, future manufacturing infrastructure (including the Fuel Factory), and commercialization efforts through commercial deployment of Lightbridge Fuel™. Planned expenditures are expected to include the continued expansion of engineering and technical personnel for research and development activities, manufacturing readiness initiatives, project development activities including constructing and operating the Pilot Factory and the Fuel Factory, testing and qualification programs, regulatory support activities, and other commercialization-related initiatives. The Company also expects to continue investing in the organizational infrastructure necessary to support these activities as it transitions from a primarily research-focused organization toward manufacturing readiness activities.

Short-Term Liquidity and Capital Resources

At September 30, 2026, we had cash and cash equivalents of $236.7 million, as compared to $201.9 million at December 31, 2025, an increase of $34.8 million. We raised net proceeds of $48.9 million from the sale of approximately 4.3 million shares of common stock during the nine months ended September 30, 2026. Our net cash used in operating activities for the nine months ended September 30, 2026, was $13.2 million. We do not anticipate any material incoming cash flows from operations for the foreseeable future, and we expect to continue funding our business primarily through our ATM program or other equity offerings.

Long-Term Liquidity and Capital Requirements

Due to the uncertainties inherent in our R&D programs and the broader industry environment, we are unable to reliably estimate our total cash requirements over the full R&D period or beyond the next 12 months. We expect our expenditures to increase over time as we advance the development and potential commercialization of our Lightbridge Fuel™. We expect that significant additional capital will be required over an extended period to advance Lightbridge Fuel™ through development and toward commercial deployment. The amount and timing of future funding needs will depend on technical progress, regulatory requirements, design and construction costs of the Pilot Factory and the Fuel Factory, partnering arrangements, and the availability of government support.

Based on preliminary estimates, we currently expect the development and construction of the Pilot Factory to require approximately $140 million of expenditures over approximately the next five years, however, the ultimate cost, timing and scope of the Pilot Factory remain subject to significant uncertainty. We expect expenditures associated with the Pilot Factory to be phased over the development and construction period rather than incurred evenly or entirely at the outset of the project. The timing and magnitude of expenditures in any particular future period will depend on, among other things, engineering and design progress, the timing of DOE and INL reviews and authorizations, procurement lead times, construction sequencing, availability of nuclear materials and equipment, and decisions regarding the timing and scope of individual phases of the project. Accordingly, actual expenditures in any particular future period may vary significantly from our current expectations. The development, construction, commissioning and operation of the Fuel Factory is expected to require substantial additional capital and is expected to significantly exceed the estimated expenditures required to construct the Pilot Factory. As of the date of this filing, the Company has not yet determined the total capital required, as the scope, design, timing and scale of this facility and related engineering, regulatory, procurement and construction requirements remain subject to further development.

Therefore, at this stage, we cannot reliably estimate the total funding required to reach commercial deployment. We currently intend to fund these activities through our existing cash and a mix of future equity financings, strategic partnerships, and potential government grants or awards, but there can be no assurance that these additional sources of capital will be made available on terms acceptable to us, or at all.

The actual amount and timing of future capital requirements will depend on several factors, including:

There is inherent uncertainty in forecasting future expenditures, and actual costs may vary materially from current estimates.

Sources of Liquidity

Our current primary source of liquidity is proceeds from our ATM equity offerings. During the nine months ended September 30, 2026, we sold approximately 4.3 million shares of our common stock under our sales agreement with Jefferies LLC, receiving net proceeds (less sales commissions and expenses) of $48.9 million.

We have a $350 million shelf registration statement on Form S-3 (File No. 333-291837). As of September 30, 2026, approximately $91.4 million of our common stock remained available for issuance and sale under the Company’s $150 million at-the-market offering program pursuant to the related prospectus supplement.

Liquidity Outlook and Risks

Although we expect our ATM offerings to remain our primary source of working capital in 2026, there are inherent uncertainties associated with our ability to continue raising capital through an ATM program. These uncertainties include potential declines in our stock price, fluctuations in the trading volume of our common stock, adverse overall stock market conditions, dilution to existing shareholders, or regulatory changes that could limit our access to capital under the current ATM arrangement. Although management believes additional public or private equity investments may be available in the future, adverse market conditions, unfavorable stock price movements, or reduced trading volumes could substantially impair our ability to raise capital when needed.

Contractual and Other Obligations

As noted previously, we have entered into PTSs with BEA, the operating contractor of INL, in collaboration with the DOE, which set forth the initial scopes of work and funding commitments under the SPPA and CRADA umbrella agreements. Performance of work under these agreements may be terminated at any time by either party, without any liability, after the effective date of termination, upon 30 days’ written notice under the SPPA and 60 days’ written notice under the CRADA. In the event of termination, the Company shall be responsible for BEA’s costs (including the closeout costs), through the effective date of termination, but in no event shall the Company’s cost responsibility exceed the total estimated cost stated in each PTS and any subsequent modification to the PTS. As of September 30, 2026, the aggregate funding commitment remaining from the Company to BEA, if and when incurred, would not exceed $25.9 million. As of September 30, 2026, we had not entered into material binding commitments for the construction of the Pilot Factory.

Cash Flow

The following table provides detailed information about our net cash flows for the nine months ended September 30, 2026 and 2025 (in millions):

Operating Activities

Cash used in operating activities increased by $5.1 million for the nine months ended September 30, 2026 as compared to the nine months ended September 30, 2025. This 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 following equity financings. The changes in working capital during the nine months ended September 30, 2026 included a $2.1 million increase in prepaid expenses and other assets and a $3.0 million increase in accounts payable and accrued liabilities, resulting in a net working capital change of $0.9 million. The changes in working capital during the nine months ended September 30, 2025 included a $1.1 million increase in accounts payable and accrued liabilities and a $0.6 million increase in prepaid expenses and other assets, resulting in a net working capital change of $0.5 million. As our R&D, manufacturing-readiness and corporate activities expand, including increased personnel and project-related expenditures, we expect cash used in operating activities to increase over time, although the amount and timing of such increases will depend on the scope, timing and progress of our development programs.

Financing Activities

Cash provided by financing activities decreased by $73.3 million for the nine months ended September 30, 2026 as compared to the nine months ended September 30, 2025. This decrease was primarily due to a $71.6 million decrease in net proceeds received from the issuance of common stock under our ATM program, a $1.2 million decrease in net proceeds from the exercise of stock options, and a $0.5 million increase in the payment of withholding taxes related to the net share settlement of equity awards.

Net cash provided by our ATM program was $48.9 million from the sale of approximately 4.3 million shares of common stock for the nine months ended September 30, 2026 and $120.4 million from the sale of approximately 9.9 million shares of common stock for the nine months ended September 30, 2025. The level of proceeds generated from our ATM program may vary significantly from period to period, and historical financing activity may not be indicative of future ATM financing activity. The amount and timing of future financing activities will depend on our cash requirements, the timing and pace of our development and commercialization activities, market conditions, the trading price and liquidity of our common stock, and the availability of alternative sources of capital.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is not required to provide the information required by this Item as it is a “smaller reporting company,” as defined in Rule 12b-2 under the Exchange Act.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) that are designed to provide reasonable assurance that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is (a) recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and (b) accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating such controls and procedures, the Company recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives.

Our management, under the supervision and with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2026.

Changes in Internal Control Over Financial Reporting

We evaluated the changes in our internal control over financial reporting and concluded that there were no changes during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

From time to time, we may become involved in various lawsuits and legal proceedings, which arise in the ordinary course of business. However, litigation is subject to inherent uncertainties, and an adverse result in these or other matters may arise from time to time that may harm our business. We are currently not aware of any such legal proceedings or claims that we believe, either individually or in the aggregate, will have a material adverse effect on our business, financial condition, or results of operations.

ITEM 1A. RISK FACTORS

Other than as set forth below, there have been no material changes to our risk factors from the risk factors disclosed in our Annual Report on Form 10-K for the year ended December 31, 2025.

The development and construction of the Pilot Factory will require substantial capital expenditures, and our current estimates of the cost, timing and scope of the project may change materially.

In connection with our participation in the U.S. Department of Energy’s (DOE) Nuclear Energy Launch Pad program, we intend to develop and construct our planned Lightbridge Fuel Pilot Factory (Pilot Factory) at Idaho National Laboratory (INL). Based on preliminary estimates, we currently expect the development and construction of the Pilot Factory to require approximately $140 million of expenditures over approximately the next five years. These estimates are preliminary and are subject to significant uncertainty.

The actual cost, timing and scope of the Pilot Factory may differ materially from our current expectations as engineering, design, procurement and construction planning activities progress. Factors that could increase costs or delay completion include changes in project scope or design, increases in the cost or availability of equipment, materials and labor, supply chain disruptions, inflation, construction delays, regulatory or governmental requirements, changes in activities conducted with INL or other third parties, technical challenges, availability of qualified personnel and other circumstances beyond our control.

The Pilot Factory requires DOE authorization, INL site access arrangements, safety and environmental approvals, availability of nuclear material/high-assay low-enriched uranium (HALEU), facility design approval, procurement and qualified nuclear personnel. As of September 30, 2026, we had not entered into material binding commitments regarding the construction of the Pilot Factory. Accordingly, our current estimates do not represent fixed or contractually committed costs, and we may revise our estimates as the project advances. In addition to the estimated development and construction costs of the Pilot Factory, we expect to incur increased personnel, operating and other expenses as we expand our technical, manufacturing, quality assurance, project management and administrative capabilities to support the Pilot Factory and our broader commercialization activities.

Although we currently expect to fund anticipated Pilot Factory expenditures from our existing cash and financial resources and, as appropriate, proceeds from equity financings, including our at-the-market offering program, our available resources must also support our other research and development, fuel qualification, regulatory, operating and commercialization activities. If the costs of the Pilot Factory exceed our current estimates, if our other expenditures increase, or if the timing of our anticipated expenditures accelerates, we may need to raise additional capital sooner than currently anticipated.

Our ability to obtain additional capital will depend on market conditions, the market price and trading volume of our common stock, our operating and development progress and other factors, many of which are outside our control. Any additional equity financing could result in substantial dilution to our existing stockholders, and financing may not be available when needed or on terms acceptable to us.

If we are unable to obtain sufficient funding, or if the development of the Pilot Factory experiences significant cost increases, delays or other difficulties, we may be required to delay, reduce the scope of, or modify our Pilot Factory development activities or other research, development and commercialization programs. Any such developments could delay the qualification, manufacturing or commercial deployment of Lightbridge Fuel™, adversely affect our business and commercialization strategy and have a material adverse effect on our financial condition and results of operations.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

On July 6, 2026, the Company issued 2,389 shares of common stock as consideration to a third party for public relations services provided to the Company, and on September 4, 2026, the Company issued 39,841 shares of common stock as consideration to a third party for their advisory services.
