Risk factors and legal proceedings
The risks LIGHTBRIDGE Corp names in Item 1A of its 10-K filed Feb 26, 2026: 33 risks under these headings, as written.5
- Risks Related to Our Business and to the Commercialization of Lightbridge Fuel™
- We will need to raise significant additional capital in the future to expand our operations and continue our R&D activities and we may be unable to raise such funds when needed on acceptable terms, or at all. Any capital raises may cause significant dilution to our shareholders.
- The amount of time and funding needed to bring our nuclear fuel to market and generate revenue may greatly exceed our projections.
- Declining Political Support or Reductions in Government Funding for Nuclear Energy Could Materially Adversely Affect Our Business.
- Our current economic model for selling our nuclear fuel may prove to be inaccurate and subject to competition and our nuclear fuel technology products may not be cost effective.
- The cost of production of our nuclear fuel could be prohibitively expensive.
- Dependence on the Future Availability of Cost-Competitive Metallic HALEU and Commercial-Scale Fuel Fabrication Infrastructure
- We have limited experience deploying and operating a dedicated nuclear fuel fabrication facility, and our lack of operational experience with a LEFF could materially and adversely affect our business.
- Changes to, or termination of, any agreements with the U.S. government national laboratories, or deterioration in our relationship with the U.S. government, could adversely affect our research and development activities.
- Development of our nuclear fuel technology is dependent upon the availability of a test reactor and access to adequate resources and manufacturing capabilities at national laboratories.
- Our fuel designs have never been tested in an existing commercial reactor and actual fuel performance, as well as the willingness of commercial reactor operators and fuel fabricators to adopt a new design, is uncertain.
- Existing commercial nuclear infrastructure in many countries is limited to uranium material in dioxide form with enrichments limited to 5%. Our nuclear fuel will be in a metallic form and will be enriched to higher levels, which will require modifications to existing commercial nuclear infrastructure and could impede commercialization of our technology.
The other 22 risks
- We are part of the nuclear power industry, which is highly regulated. Our fuel designs differ from fuels currently licensed and used by commercial nuclear power plants. The regulatory licensing and approval process for nuclear power plants to operate with our nuclear fuels may be delayed and made more costly, and industry acceptance of our nuclear fuels may be hampered.
- Successful execution of our business model is dependent upon public support for nuclear power and overcoming public opposition to nuclear energy.
- Our nuclear fuel fabrication process is dependent on outside suppliers of nuclear and other materials and any difficulty by us and/or a future fuel fabricator partner in obtaining these materials could be detrimental to our ability to eventually market our nuclear fuel either directly or through a future fuel fabricator partner.
- We rely on a limited number of suppliers for HALEU or other key source materials and/or key components and/or key equipment necessary for the development and fabrication of our nuclear fuel, which could, under certain circumstances, adversely delay our research and development activities.
- Labor shortages and supply chain disruptions could prevent us from meeting our R&D timelines and have a negative impact on our financial results.
- If the price of non-nuclear energy sources falls, whether as the result of government policy or otherwise, there could be an adverse impact on nuclear energy, which would have a material adverse effect on our operations.
- We are dependent on management and key personnel for our success, and the loss of which could have a material adverse effect on our business.
- We may not be able to receive or retain authorizations that may be required for us to sell or license our technology internationally.
- Potential competitors could limit opportunities to license our technology.
- If the DOE were to successfully assert that an invention claimed within our 2007 or 2008 Patent Cooperation Treaty, or PCT, patent applications was first conceived or actually reduced to practice under a contract with the DOE, then our intellectual property rights in that invention could become compromised and our business model could become significantly impeded.
- If we infringe or are alleged to infringe intellectual property rights of third-parties, our business, financial condition, and results of operations could be adversely affected.
- The occurrence of cybersecurity incidents, or a deficiency in our cybersecurity or the cybersecurity of our service providers, could negatively impact our business by causing disruptions to our operations, a compromise or corruption of our confidential information, regulatory enforcement and other legal proceedings, and/or damage to our business, all of which could negatively impact our financial results.
- AI and generative AI applications present risks and challenges that can impact our business.
- Technological changes could render our technology and products uncompetitive or obsolete, which could prevent us from achieving market share and sales.
- We may acquire other companies or technologies, which could divert our managements’ attention, result in dilution to our stockholders and otherwise disrupt our operations and adversely affect our operating results.
- If we are unable to obtain or maintain intellectual property rights and trade secrets relating to our technology, the commercial value of our technology may be adversely affected, which could in turn adversely affect our business, financial condition, and results of operations.
- Material weaknesses in our internal control over financial reporting may be identified, which could adversely affect our ability to provide accurate and timely financial statements and harm investor confidence.
- Risks Related to the Ownership of Our Common Stock
- The issuance of additional stock in connection with financings, acquisitions, investments, our stock incentive plans or otherwise will in some circumstances dilute our stockholders.
- We may issue preferred stock with rights senior to our common stock.
- There may be volatility in our stock price, which could negatively affect investments, and our stockholders may not be able to resell their shares at or above the value they originally purchased such shares.
- Our ability to utilize our net operating loss carryforwards to offset future taxable income will be limited and may also expire.
- Shareholder activism could cause us to incur significant expense, hinder execution of our business strategy and impact our stock price.
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. To our knowledge, the Company does not have any current pending legal issues or proceedings.
