Current report

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.

Current report

The Company is evaluating a potential site location and developing a conceptual design for a Lightbridge Expandable Fuel Facility (LEFF) to support the possible future fabrication of Lightbridge Fuel™ for use in commercial reactors. The Company also continually evaluates a variety of strategic opportunities that could accelerate the commercialization of its advanced nuclear fuel technology, including the potential establishment of a pilot-scale fuel fabrication capability to support the future manufacture of LTAs.

Current report

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. For example, the Company recently submitted an application to the U.S. Department of Energy (DOE) seeking authorization and collaboration through the agency’s Nuclear Energy Launch Pad program relating to such a pilot-scale fuel fabrication capability. The requested authorization, if obtained and ultimately pursued by the Company, could enable earlier fabrication and testing of LTAs and accelerate the Company's commercialization timeline.

Current report

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.

Current report

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.

Current report

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.

Current report

During the first half of 2026, the Company continued accelerating the development of Lightbridge Fuel™. Operating expenses increased for the three and six months ended June 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.

Previous report

In January 2025, we entered into a Memorandum of Understanding (MOU) with Oklo, Inc. (Oklo), a developer of advanced micro-reactors designed to provide clean, reliable, and affordable energy. The MOU contemplates potential areas of collaboration, including: (i) a preliminary evaluation of the feasibility of co-locating a Lightbridge commercial-scale fuel fabrication facility with Oklo’s proposed commercial fuel fabrication facility; (ii) exploring opportunities for collaboration on the reprocessing and recycling of spent uranium-zirconium fuel; and (iii) evaluating other potential areas of mutual interest. In April 2026, the term of the MOU was extended through December 31, 2026.

Previous report

During our preliminary evaluation of co-location at Oklo’s proposed Idaho Falls site, we identified regulatory considerations associated with the application of different licensing frameworks, including oversight by the DOE for Oklo’s proposed activities and the U.S. Nuclear Regulatory Commission for our commercial fuel fabrication facility. Based on these considerations, co-location at this site with Oklo under separate licensing frameworks is not currently being pursued. We are currently evaluating potential sites for a standalone Lightbridge fuel fabrication facility.

Previous report

We also continue to contemplate co-locating a Lightbridge fuel fabrication facility with an Oklo facility at a site where a coordinated licensing approach may be implemented, and we continue to assess the potential collaboration opportunities with Oklo in areas such as recycling and reprocessing of spent uranium-zirconium fuel; however, no definitive agreements have been reached, and there can be no assurance that any such collaboration will be realized.

Previous wording

At Lightbridge, we are developing next generation nuclear fuel for water-cooled reactors that could significantly 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. Data centers will need massive, constant power that we believe nuclear power can provide. Advances in reactor technology, combined with growing corporate and governmental support for clean energy, can position nuclear power as a cornerstone of future energy strategies for data-intensive industries, which may be willing to pay a premium for reliable, clean, and sustainable baseload electricity.

Development of a Pilot-Scale Facility and Future Lightbridge Expandable Fuel Facility

Previous wording

The Company is evaluating a potential site location and working on a conceptual design for a Lightbridge Expandable Fuel Facility (LEFF) to support the possible future fabrication of Lightbridge Fuel™ for use in commercial reactors. The construction of such a facility might commence as early as late 2027, subject to various factors, including those described below. This initiative would represent a significant potential expansion of the Company’s operations beyond its current R&D activities. 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, and construct the LEFF would be substantial. 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 fabrication facility.

Previous wording

In 2022, we entered into agreements with Batelle Energy Alliance, LLC (BEA), the U.S. Department of Energy’s (DOE) operating contractor for Idaho National Laboratory (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 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 will support fuel performance modeling and regulatory licensing efforts for commercial deployment of Lightbridge Fuel™. We use 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.

Previous wording

In April 2026, the Company entered into SPPA PTS No. 6 to support the development of coextruded fuel rod components for future irradiation testing. 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 Advanced Test Reactor (ATR) at INL. 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. Actual expenditures may differ from this amount based on the scope and timing of work performed through the issuance of additional PTSs to BEA. 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.

Cash used in operating activities increased by $1.5 million for the three months ended March 31, 2026 as compared to the three months ended March 31, 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 in the three months ended March 31, 2026, which included an increase in prepaid expenses and other assets of $1.4 million, were partially offset by an increase in accounts payable and accrued liabilities of $0.4 million.
