Item 1. Business

Overview

We founded Oklo in 2013 with the goal of revolutionizing the energy landscape by developing clean, reliable, affordable energy solutions at scale. According to the International Energy Agency, global electricity production is expected to increase over 75% by 2050 driven by electrification of buildings, transportation, and industry; increased use of air conditioning in the developing world; and increased consumption from data centers and cloud services. Our business addresses this demand by producing electricity and heat from our Aurora powerhouses which can run on fresh, recycled, or down-blended nuclear fuel. We are also commercializing nuclear fuel recycling technology that can convert used nuclear fuel into usable fuel for our powerhouses and those of others.

The fast fission reactor technology we are commercializing was demonstrated by the Experimental Breeder Reactor-II (“EBR-II”), a fast fission plant that was operated by the U.S. government for 30 years. Our powerhouse product line, called the “Aurora,” builds on this legacy of proven and demonstrated technology. Our Aurora powerhouse product line is designed with embedded safety features, to be able to run on fresh, recycled, or down-blended fuel, and to produce 15-75 megawatts electric (“MWe”) and has the potential to expand powerhouse size to produce 100 MWe and higher. Because the Aurora powerhouses are designed to operate by harnessing the power of high-energy, or “fast,” neutrons, they are expected to be able to tap into the vast energy reserves remaining in existing used nuclear fuel from conventional nuclear power generation facilities, which only use approximately 5% of the energy content stored in nuclear fuel before needing to refuel. The U.S. nuclear power industry has produced approximately 20% of U.S. electricity over the last 30 years and generated over 90,000 metric tons of used nuclear fuel. We estimate that the existing energy reserves contained in the used nuclear fuel in the U.S. that are made accessible through our fast fission reactor technology are equivalent to approximately 1.2 trillion barrels of oil equivalent (BOE), nearly five times the oil reserves of Saudi Arabia. Fission is an energy-dense process, producing approximately 50 million times more energy than combustion.

We have achieved several significant deployment and regulatory milestones for our first Aurora powerhouse. Notably, we secured a site use permit from the U.S. Department of Energy (“DOE”) for the Idaho National Laboratory (“INL”) site and received a fuel award of five metric tons of HALEU produced from recovered uranium from previously irradiated EBR-II fuel from INL for a commercial Aurora powerhouse in Idaho. Related to the construction and operating licensing process of the Aurora powerhouse, we have also submitted the Nuclear Safety Design Agreement and the Preliminary Documented Safety Analysis to the DOE for the Aurora powerhouse at INL ("Aurora-INL"), which represent the first two of five steps in the DOE regulatory pathway for nuclear facility operation. Early in 2026, the DOE approved the Nuclear Safety Design Agreement. Related to our first Aurora powerhouse, the DOE and the INL have completed the environmental compliance process addressing the DOE requirements for site characterization. This process, resulting in an Environmental Compliance Permit, marks a milestone as we advance our plans to deliver the first commercial advanced fission power plant in the U.S.

On May 9, 2024, we consummated a business combination pursuant to an Agreement and Plan of Merger and Reorganization dated July 11, 2023 (as amended, modified, supplemented, or waived, the “Merger Agreement”), by and between AltC Acquisition Corp. (“AltC”) and Oklo Technologies, Inc. (the “Recapitalization”). Prior to the Recapitalization, Oklo Technologies, Inc. was formerly known as Oklo Inc. (referred to herein as “Legacy Oklo”). Upon consummation of the Recapitalization, AltC changed its name to Oklo Inc. See Note 3—Business Combinations—Recapitalization in our accompanying consolidated financial statements for additional information.

On September 25, 2024, we announced the finalization of a Memorandum of Agreement (“MOA”) with the DOE Idaho Operations Office. This MOA grants us access to conduct site investigations at the identified preferred site in Idaho, marking a key step toward the next phase of site preparation and construction.

On February 28, 2025, we acquired Atomic Alchemy Inc. ("Atomic Alchemy"), a radioisotope business located in the U.S. We paid some of Atomic Alchemy’s investors cash of approximately $1.0 million and exchanged 820,840 shares of our Class A common stock, par value $0.0001 per share (“common stock”), with a price per share of $33.39 at the acquisition date, representing approximately $27.4 million of stock consideration. In addition, we issued 274,339 shares of our common stock, subject to certain lock-up provisions, vesting conditions, and substantial risk of forfeiture, representing post-combination services, pursuant to an employment agreement and vesting agreement. The purchase consideration was paid in exchange for all of Atomic Alchemy's outstanding common stock. See Note 3—Business Combinations—Atomic Alchemy in our accompanying consolidated financial statements for additional information.

In December 2025, we purchased land in southern Ohio that we have announced we intend to use to support Aurora powerhouses, including support of a planned 1.2 gigawatt power campus in Pike County, Ohio in connection with a

prepayment agreement with Meta Platforms, Inc. (as further described under —Recent Developments—Prepayment Agreement). Furthermore, we have been tentatively selected to provide electricity and heat to Eielson Air Force Base outside of Fairbanks, Alaska. Our robust pipeline of potential customer engagements spans a number of industries. For example, we have signed non-binding letters of intent with Equinix, Inc. ("Equinix"), Diamondback E&P LLC ("Diamondback Energy"), and Prometheus Hyperscale (formerly Wyoming Hyperscale White Box LLC) ("Prometheus Hyperscale"). In December 2024, we signed a 12 gigawatt (GW) Master Power Agreement with Switch, Ltd. ("Switch"), one of the largest corporate power purchase agreements ("PPA") in history. We are exploring opportunities with the Tennessee Valley Authority (“TVA”) to recycle the utility’s used fuel at a new facility and to evaluate potential power sales from future Oklo powerhouses in the region to TVA. The market interest in our solutions exemplifies the potential demand for the size range of the Aurora powerhouse product line and our differentiated business model. We have an ambitious target of deploying our first powerhouse in 2028 amidst a range of supply chain, construction, macroeconomic, and design complexities.

In addition to deployment milestones, we have made significant progress in our nuclear fuel recycling and fuel fabrication efforts and in securing fuel. The DOE has reviewed and approved our Safety Design Strategy, Conceptual Safety Design Report, Nuclear Safety Design Agreement, and Preliminary Documented Safety Analysis for the Aurora Fuel Fabrication Facility at INL—all key milestones as we advance toward our goal of utilizing recovered nuclear material to fuel our first commercial Aurora powerhouse. Our Aurora Fuel Fabrication Facility was also selected under the DOE Fuel Line Pilot Program ("FLPP"). The FLPP allows for acceleration of permitting, construction, and operation of nuclear fuel production lines for research, development, and demonstration purposes, supporting a fast-track approach to commercial licensing. In addition, we successfully completed the first end-to-end demonstration of the key stages of our advanced fuel recycling process, in collaboration with Argonne and INL. This marks a significant step forward in scaling up fuel recycling capabilities and deploying a commercial-scale recycling facility. In September 2025, we announced plans to design, build, and operate a fuel recycling facility in Tennessee as the first phase of an advanced fuel center (the "Advanced Fuel Center") to recycle used nuclear fuel into fuel for fast reactors, including our Aurora powerhouse line. The facility, which includes a roadmap of up to $1.68 billion in investment, will be the first of its kind in the U.S. and we estimate that it has the potential to create more than 800 high-quality jobs. We have completed a licensing project plan for the fuel recycling facility with the NRC and are currently in pre-application engagement with the regulator’s staff.

In December 2025, we completed a fast-spectrum plutonium criticality experiment in collaboration with Los Alamos National Laboratory under the DOE’s reactor pilot program ("RPP"). During the experiment, the system was taken critical and operated through controlled power maneuvers and transients, enabling the collection of operating data related to reactivity feedback and power response. This work places Oklo among a limited number of organizations with modern, experimentally validated operating data for plutonium-fueled fast-spectrum reactor systems, providing empirical validation of key safety and performance characteristics. Plutonium represents a potential near-term fuel option within a DOE-managed framework that complements Oklo’s use of HALEU and longer-term fuel recycling strategy, providing additional flexibility as fuel markets evolve and supporting continued progress toward deployment in alignment with U.S. national priorities.

Fuel is a significant input to enable us to build and operate our powerhouses at scale and generate expected returns. The cost environment for various sources of fuel (including HALEU) has increased significantly in recent years, which is why we are implementing a diversified fuel strategy. Tariffs, supply chain constraints, inflation, and evolving sanctions have impacted the market dynamics around fuel costs and availability. In particular, beyond developing recycling and fuel fabrication facilities, we are evaluating the use of alternative fuel materials, including plutonium currently designated for the DOE’s dilute-and-dispose programs, that may be made available by the U.S. government for use in advanced reactor applications. Any potential use of such materials would be subject to DOE authorization, applicable regulatory approvals, applicable cost recovery requirements, and programmatic determinations regarding material availability. By developing a diverse set of sources of fuel (including plutonium) with a wide range of costs, levels of regulatory oversight, and operational complexities, and having multiple options for fueling our powerhouses, we believe we will better navigate the shifting fuel landscape.

Our Business Model

We are developing next-generation fast fission power plants called “powerhouses.” In our differentiated build, own, and operate business model, we plan to sell power in the forms of electricity and heat directly to customers, which we believe can allow for fast-tracked customer adoption. In addition, we are a leader in the nuclear industry in the development of advanced fuel recycling, which can unlock the energy content of used nuclear fuel; we also believe this aspect of our business can complement our market position by vertically integrating and securing our fuel supply chain. In addition to our powerhouse and fuel recycling development, we are progressing construction of a pilot scale fuel fabrication facility and building plans for a first‑of‑a‑kind new commercial scale fuel fabrication facility. Through our wholly owned subsidiary, Atomic Alchemy, we are combining our growing expertise in building and operating powerhouses and nuclear

fuel recycling with Atomic Alchemy’s expertise in radioisotope production. Together, we aim to meet the increasing demands for radioisotopes in medical, energy, industry, defense, and artificial intelligence applications.

Our primary product will be the energy produced from our Aurora powerhouses once operational. Our primary business model is to sell the energy to customers through PPAs, as opposed to selling our powerhouse designs. This business model allows for recurring revenue, provides the opportunity to capture profitability of an Aurora powerhouse upon improved operational efficiency, and enables project financing structures. This business model sets us apart from the traditional nuclear power industry, which typically sells reactor design and engineering services to large scale utility customers and not power. Selling power through PPAs is a common practice within the renewable energy and utility sectors and indicates that this business model could be feasible for power plants within the size range targeted by our Aurora product line (i.e., 15 MWe-75 MWe, and ranging upward to potential sizes of 100 MWe and higher).

The traditional nuclear power industry comprises developers of large (ranging from approximately 600 MWe to over 1,000 MWe) light water reactors that sell or license their reactor designs to large utilities that then construct and operate the nuclear power plant. The developer’s focus on regulatory approval of the design may lock in certain lifecycle regulatory costs that are realized by the owner-operator during construction and operations. As a result, lifecycle cost implications are generally not addressed cohesively between the developer and the owner-operator, and the regulatory strategy does not holistically implement the lifecycle benefits of the technology’s inherent safety characteristics. The advanced fission industry has largely followed the historical blueprint of developers seeking design certifications or approvals, and utilities bearing the future burden of licensing for construction and operations. While there are a number of advanced reactor designers developing smaller sized reactors than those traditionally used in the nuclear power industry, many of these developers are generally pursuing regulatory approval of groupings of these smaller reactors as part of singular larger plants, sizes of 200 MWe and up to 1,000 MWe.

In contrast, we plan to be the designer, builder, owner, and operator of our powerhouses and plan to focus on small-scale powerhouses (15 MWe-75 MWe, and potentially 100 MWe and higher). As a result, we have an incentive to relentlessly focus on the full lifecycle of a safe, well-maintained, cost-effective powerhouse and holistically implement the benefits of an inherently safe, simple design. We expect this approach to enable us to reduce and manage lifecycle regulatory and operating costs in an integrated fashion over time, as opposed to the historical model used in the nuclear power industry, which divides the incentives and responsibilities between the developer and the utility.

Additionally, this modular and scalable approach enables us to better deal with the inherent uncertainties, costs, and inefficiencies of the many service providers, manufacturers, fuel providers, and other third parties that we will rely on to build our powerhouses. While we expect that individual powerhouses may, and our first few powerhouses likely will, experience challenges that require us to manage unexpected costs and possible construction delays, our business model allows us to take the learnings from constructing those powerhouses and make improvements with future projects.

In particular, we expect the construction of our first powerhouses, such as the powerhouse at INL, to include additional, unique, one-time costs as compared to the costs expected for future powerhouse projects. Such additional costs will result, in part, from design decisions to include enhanced fuel and core testing capabilities, which will be more costly and complex to design and build. These complexities will also increase the possibility of construction delays. We expect future powerhouses to benefit from substantial cost reductions as compared to the deployment of our first few reactors, both because subsequent reactors will not require these enhanced testing capabilities, and because we expect the testing capabilities to help us identify opportunities to reduce our costs and improve our operational efficiency over time.

Selling electricity under PPAs follows an established revenue model in global power markets. While this model is more typically used for renewable energy solutions, we believe it is a compelling model for us because of the relatively small size and the lower expected capital costs of our powerhouses, when compared with other nuclear power plants. In addition, our model is designed to generate recurring revenue in a way that the traditional licensing model does not. Our powerhouses could be operating cash flow positive from the first year of operation due to our anticipated favorable unit economics. We also believe this approach will drive unit growth and allow us to ultimately launch higher output versions of our powerhouses. As our technology matures, we intend to offer customers flexibility in business model and deployment solutions to meet their needs, providing us with the largest target customer base possible. Given our growth stage, we continue to develop and evaluate our overall cost and potential pricing structure as we evaluate our unit economics, which we expect to be subject to market and extrinsic forces such as the impact of construction costs as a result of tariffs, supply chain pressures, and other macroeconomic factors.

In addition to selling power under PPAs, we are taking steps to enhance our mission with our fuel fabrication projects and advanced nuclear fuel recycling technology. We are actively developing nuclear fuel recycling capabilities with the goal of deploying a commercial-scale fuel recycling facility in the U.S. by the early 2030s. Used nuclear fuel still contains approximately 95% of its energy content, and it has been estimated there is enough energy in the form of used nuclear fuel in the U.S. to power the expected electrical needs in the U.S. for 100 years with fast fission power plants. According to the DOE, more than 90,000 metric tons of used nuclear fuel have been generated since 1950, and an additional 2,000 metric tons are generated every year. Currently, other countries recycle used nuclear fuel, but the U.S. does not, and hence there is an enormous opportunity to do so.

Our reactors are specifically designed to run on fresh, recycled, or down-blended nuclear fuel, and nuclear fuel recycling and down-blending federal government materials could provide future margin uplift for our power sales business, as well as the potential for new revenue streams. We continue to evaluate the overall cost and timeline to be able to receive any potential benefit from this embedded opportunity. We are also evaluating the potential use of alternative fuel materials, including plutonium designated for dilute-and-dispose programs, that could be made available by the U.S. government for use in advanced reactors. This initiative complements our recycling work and supports the development of a resilient and diversified domestic fuel supply chain.

Recent Developments

ATM Program

On December 4, 2025, we entered into an equity distribution agreement with sales agents pursuant to which we may offer and sell, at our sole discretion, shares of our common stock up to an aggregate gross sales price of $1,500.0 million in an "at-the-market" ("ATM") offering (the "December ATM Program"). From December 4, 2025 to December 31, 2025, we sold 3,397,872 shares of our common stock through the sales agents at an average price of $88.29 per share, resulting in aggregate gross proceeds of $300.0 million. The December ATM Program was closed on January 28, 2026. See Note 16 —Subsequent Events for additional details.

Prepayment Agreement

On January 5, 2026, we entered into a prepayment agreement (the "Prepayment Agreement") with Meta Platforms, Inc. (“Meta”) that advances plans to develop a 1.2 gigawatt power campus in Pike County, Ohio, to support Meta’s data centers. The Prepayment Agreement provides a mechanism for Meta to prepay for power and provide funding to advance powerhouse deployment. Pursuant to the Prepayment Agreement, the Company will use Meta's funding to secure nuclear fuel, advancing the first phase of the project.

Radioisotope Pilot Facility Other Transaction Agreement

On January 7, 2026, we announced the execution of a DOE Other Transaction Agreement ("OTA") to support the design, construction, and operation of a radioisotope pilot plant (“Radioisotope Pilot Facility”) under the DOE RPP. The execution of the OTA marks the transition from project selection and planning into active execution under DOE authorization. Atomic Alchemy will use the Radioisotope Pilot Facility to aid in planning and execution of future commercial radioisotope production facilities and may be used for testing radioisotope production methods to further our capability to produce medical and research radioisotopes in the U.S., as well as furthering our research efforts and building capabilities for other projects in development.

Key Factors Affecting Our Performance

We believe that our future success and financial performance depend on a number of factors that present significant opportunities for our business, but also pose risks and challenges. As a result, we are subject to continuing risks and uncertainties. For additional information, see the section titled “Risk Factors” in Part I, Item 1A of this Annual Report.

Product Development Plan

We plan to leverage the next-generation fast fission powerhouses that we are developing in order to sell power to a variety of potential customers, including data centers, military and other government facilities, factories, industrial customers, off-grid and remote communities, commercial and institutional campuses, and utilities.

Commercial deployment of any advanced fission power plant requires obtaining regulatory approvals for design, construction, and operation. Our long-term regulatory strategy has been focused on a custom combined license application. We became the first advanced fission company to submit a custom combined license application with the NRC in March 2020, which was denied without prejudice in 2022. We are currently working toward submitting an updated custom combined license application for NRC review.

In July 2025, we completed a Phase I pre-application readiness assessment with the NRC to evaluate the maturity of our siting and environmental approach and our overall readiness to submit those parts of the combined license application. The assessment concluded with no significant gaps identified that would hinder acceptance of the application, marking a key milestone in our licensing strategy. It is uncertain when, if at all, we will obtain NRC approvals for the design, construction, and operation of any of our powerhouses. Our financial condition, commercial plans, and results of operation are likely to be materially and adversely affected if we do not obtain such approvals or if this process takes significantly longer or costs more than we expect.

Alongside ongoing NRC progress, on August 13, 2025, Oklo and Atomic Alchemy were selected by the DOE for three of the eleven projects awarded under the newly established RPP. Oklo was selected for two projects, and Atomic Alchemy for one project. Among these, the Aurora–INL powerhouse was approved to proceed under DOE purview, granting access to the DOE authorization pathway—a regulatory framework that provides full authority to construct and operate the powerhouse while maintaining high safety standards. This designation supports deployment of the Aurora–INL powerhouse by streamlining federal review and providing a platform for demonstration of the Aurora powerhouse design to support future NRC licensing.

In August 2025, the NRC accepted for review our PDC topical report, which establishes a regulatory framework that defines the fundamental safety, reliability, and performance requirements to guide future reactor licensing and design activities. The NRC accepted our PDC topical report under an accelerated timeline and proposed an expedited review schedule of the report.

Additionally, we plan to be the designer, builder, owner, and operator of our powerhouses and plan to focus on small-scale powerhouses (15 MWe, 75 MWe, and potentially 100 MWe and higher designs). As a result, we have an incentive to relentlessly focus on the full lifecycle of a safe, well-maintained, cost-effective powerhouse and holistically implement the benefits of an inherently safe, simple design. We expect this approach to enable us to reduce and manage lifecycle regulatory and operating costs in an integrated fashion, as opposed to the historical model used in the nuclear power industry, which divides the incentives and responsibilities between the developer and the utility. However, this model exposes us directly to the costs of building, owning, and operating our powerhouses. Our cost projections and timelines are heavily dependent upon fuel, raw materials (such as steel), equipment, and technical and construction service providers (such as engineering, procurement, and construction firms). The global supply chain on which we will rely (including for HALEU), has been significantly impacted in recent years by inflation, instability in the banking sector, war and other hostilities, and other economic uncertainties, resulting in potential significant delays and cost fluctuations. Similar developments in the future may impact our performance from both a deployment and cost perspective. Our initial assets in operation will represent the first deployment of our Aurora design and, as such, will be subject to risk around both cost and time to associated with first-of-a-kind capital project delivery. In particular, we expect the construction of our first powerhouse at INL to include additional, unique costs as compared to the costs expected for future powerhouse projects. Such additional costs will result, in part, from design decisions to include enhanced fuel and core testing capabilities, which will be more costly and complex to design and build. We expect future powerhouses to benefit from substantial cost reductions as compared to our first reactor deployment.

Plan of Operations

To further our ambitious target of deploying our first powerhouse in 2028, amidst a range of supply chain, geopolitical, macroeconomic, and design complexities, we will engage or continue to engage in the following key initiatives:

•Progressing regulatory approval for powerhouse deployments with both the DOE and the NRC.

•Progressing regulatory pre-application related activities with the NRC for licensing of commercial fuel fabrication.

•Progressing engineering procurement and construction activities in support of the construction of Aurora powerhouses.

•Working with Kiewit Nuclear Solutions Co. ("Kiewit"), who was selected as the lead constructor for our first Aurora powerhouse in Idaho, a major milestone toward project delivery and execution.

•Continuing and initiating site preparation for announced facilities at INL, and Pike County, Ohio, respectively. We will begin site preparation for other announced projects based on prioritization, potentially including prospective customers such as Meta Platforms, Inc., Equinix, Diamondback Energy, Prometheus Hyperscale, Switch, and other future projects.

•Exploring activities related to, or in support of, various Executive Orders that look to accelerate the deployment of domestic, advanced nuclear energy.

•Negotiating and executing additional letters of intent, memoranda of understanding, and master partnership agreements and converting such preliminary agreements into purchase power agreements with multiple potential customers.

•Negotiating term sheets and binding power purchases agreements with customers who have previously signed nonbinding agreements such as letters of intent to purchase power.

•Continuing to hire additional personnel and implement processes and systems necessary to deliver our business strategy.

•Progressing production of radioisotopes by Atomic Alchemy, assessing options to scale production, developing and executing plans to progress the RPP deployment for this business, as well as obtaining the NRC license required to handle, manufacture, and distribute radioisotopes.

•Evaluating potential acquisition opportunities to strategically accelerate our business and enhance our capability to execute on our business plans.

•Continuing to pursue activities, such as our ATM Program, to raise capital at the corporate and asset levels.

For the years ended December 31, 2025 and 2024, our total operating expenses were $139.3 million and $52.8 million, respectively. We expect our total cash used in operating expenses for 2026 to be in the range of $80 million to $100 million and our total cash used in investing activities to be in the range of $350 million to $450 million.

Nuclear Energy Industry

The nuclear energy industry operates in a politically sensitive environment, and the successful execution of our business model is dependent upon public support for nuclear power in the U.S. and other countries. The U.S. government has consistently indicated through bipartisan action that it recognizes the importance of nuclear power in meeting the United States’ growing energy needs. As an example, the ADVANCE Act, which was signed into law on July 9, 2024 with significant bipartisan support, streamlines licensing, reduces costs, and boosts U.S. leadership in advanced nuclear energy by modernizing regulations, supporting fuel innovation, and expanding global competitiveness.

On May 23, 2025, four Executive Orders directed federal agencies to streamline licensing at the NRC, accelerate advanced reactor deployment at DOE and DOD sites for national security and AI/data-center needs, overhaul the domestic nuclear fuel cycle, and strengthen the U.S. nuclear industrial base. These Executive Orders, together with proposed legislation, reflect sustained federal interest in strengthening domestic energy security, supporting AI-driven infrastructure growth, and promoting advanced nuclear deployment. Ongoing DOE initiatives, including the RPP and FLPP, further demonstrate federal focus on developing a resilient nuclear fuel cycle and advancing advanced reactor technologies.

Additionally, opponents of advanced nuclear deployment in the U.S. and intervenors in regulatory proceedings could delay the licensing that our business model requires. As a result, our performance will depend in part on factors generally affecting the views and policies regulating the nuclear energy industry, which we cannot predict over the long term.

Competition

Our competitors include other power generation technologies, including traditional baseload power producers, other advanced nuclear technologies, renewables with or without storage, advanced energy storage, fossil fuels with carbon capture, and combinations of these technologies.

•Traditional baseload power — Includes natural gas, coal, oil, and large-scale nuclear.

•Fossil fuels with carbon capture — Sources provide firm, baseload power but require carbon capture technology to provide clean power. Carbon capture has not been demonstrated to be economically scalable.

•Renewables with or without energy storage — Wind and solar provide clean energy but cannot provide firm, baseload energy due to their intermittency. When paired with energy storage, they can provide a more dispatchable energy supply, but battery storage technology has not been demonstrated to be scalable or cost-effective.

•Other advanced nuclear reactors — There are several advanced reactor technologies in various stages of development, including high-temperature gas reactors, molten salt reactors, fusion technologies, and advanced light water reactor designs.

Intellectual Property

We protect our intellectual property through a combination of patents, trademarks, domain names, copyrights, and trade secrets. We currently hold U.S. patents and have patent applications pending in a number of different jurisdictions that cover a range of different technologies relevant to our technology roadmap and anticipated areas of development. We acquire patents and technology licenses when we consider it advantageous for us to do so. Although in the aggregate our patents and technology licenses are important to us, we do not regard any single patent or license or group of related patents or licenses as critical or essential to our business as a whole. Beyond patents, we also take steps to contractually restrict counterparties from disclosing our confidential or proprietary information in our agreements with employees, consultants, contractors, vendors, and business partners.

Additional information regarding certain risks related to our intellectual property is included in Part I, Item 1A, “Risk Factors.”

Government Regulations

We are subject to numerous U.S. federal, state, and local, as well as foreign laws and regulations covering a wide variety of subjects relating to our operations, and the scope of this coverage continues to broaden with continuing new legal and regulatory developments in the U.S. and internationally. In particular, we must comply with a range of laws and regulations including those relating to nuclear energy, nuclear materials (including fuels on which we rely, such as HALEU and plutonium-based fuels), the environment, export controls, national security, and other broad areas of law.

Like other companies involved in the generation of nuclear energy, we deal with intense scrutiny from both U.S. and foreign governments with respect to our compliance with laws and regulations. Many of these laws and regulations are evolving and their applicability and scope, as interpreted by agencies or the courts, remain uncertain. Some of these laws

and regulations require that certain aspects of our operations, facilities, and business model be licensed or approved by specific regulators, including the DOE and the NRC. Particularly with regard to our operations, U.S. regulators (including the NRC) have limited precedent dealing with business models and product roadmaps like ours, which may make regulatory and licensing discussions more complicated than with more traditional providers (e.g., providers designing and building light water reactor plants).

Additionally, we work in close collaboration with the DOE’s National Laboratories and various other governmental bodies (e.g., the U.S. Department of War and various state or local bodies). These collaborations often impose legal and/or contractual restrictions on us that arise out of laws or regulations that may otherwise not apply to private commercial businesses.

Our compliance with these laws, regulations, and contractual commitments may be onerous and may, individually or in the aggregate, increase our cost of doing business, impact the financial viability of our business model, limit our ability to pursue certain business practices or offer certain products and services, cause us to change our business models and operations, affect our competitive position relative to our peers, and/or otherwise harm our business, reputation, financial condition, and operating results.
