PART I

Item 1.Business

Overview

Centrus Energy Corp., a Delaware corporation, is a trusted supplier of enriched uranium for nuclear fuel and services for the nuclear power industry, which provides a reliable source of carbon-free energy. References to “Centrus”, the “Company”, “our”, or “we” include Centrus Energy Corp. and its wholly-owned subsidiaries as well as the predecessor to Centrus, unless the context otherwise indicates. We were incorporated in 1998 as part of the privatization of the United States Enrichment Corporation.

Centrus operates two business segments: (a) low-enriched uranium (“LEU”), which supplies various components of nuclear fuel to commercial customers from our global network of suppliers, and (b) technical solutions, which provides advanced engineering, design, and manufacturing services to government and private sector customers and is deploying uranium enrichment and other capabilities necessary for production of advanced nuclear fuel to power existing and next-generation reactors around the world.

Our LEU segment provides most of the Company’s revenue and involves the sale of enriched uranium for nuclear fuel to customers that are primarily utilities which operate commercial nuclear power plants. The majority of these sales are for the enrichment component of LEU, which is measured in separative work units (“SWU”). Centrus also sells natural uranium (the raw material needed to produce LEU) and occasionally sells LEU with the natural uranium, uranium conversion, and SWU components combined into one sale.

LEU is a critical component in the production of nuclear fuel for reactors that produce electricity. We supply LEU and its components to both domestic and international utilities for use in nuclear reactors worldwide. We provide LEU from multiple sources, including our inventory, medium and long-term supply contracts, and spot purchases. As a long-term supplier of LEU to our customers, our objective is to provide value through the reliability and diversity of our supply sources.

Our global order book includes long-term sales contracts with major utilities to 2029. We have secured cost-competitive supplies of SWU under long-term contracts through the end of this decade to allow us to fill our existing customer orders and make new sales. A market-related price reset provision in our largest supply contract took effect at the beginning of 2019 – when market prices for SWU were near historic lows – which has significantly lowered our cost of sales and contributed to improved margins.

In October 2020, the U.S. Department of Commerce (“DOC”) reached agreement with the Russian Federation on an extension of the 1992 Russian Suspension Agreement, a trade agreement which allows for Russian-origin nuclear fuel to be exported to the United States in limited quantities, with an import quantity in each year. The two parties agreed to extend the agreement through 2040 and to set aside a significant portion of the quota for Centrus’ shipments to the United States through 2028 to execute our long-term supply (purchase) agreement (the “TENEX Supply Contract”) with the Russian government entity, TENEX, Joint-Stock Company (“TENEX”). This outcome also allows sufficient quota for Centrus to continue serving its utility customers. Refer to Item 1A Risk Factors - Operational Risks for further discussion.

Under a contract with the U.S. Department of Energy (“DOE”), our technical solutions segment is deploying uranium enrichment and other capabilities necessary for production of advanced nuclear fuel to meet the evolving needs of the global nuclear industry and the U.S. government. We also are leveraging our unique technical expertise, operational experience, and specialized facilities to expand and diversify our business beyond uranium enrichment, offering new services to existing and new customers in complementary markets.

Our technical solutions segment is working to restore America’s domestic uranium enrichment capability, to play a critical role in meeting U.S. national security and energy security requirements, in advancing America’s nonproliferation objectives and in delivering the next-generation nuclear fuels that will power the future of nuclear energy as it provides reliable carbon-free power around the world.

The United States has not had domestic uranium enrichment capability suitable to meet U.S. national security requirements since the Paducah Gaseous Diffusion Plant (“Paducah GDP”) shut down in 2013. Longstanding U.S. policy and binding nonproliferation agreements prohibit the use of foreign-origin enrichment technology for U.S. national security missions. Our AC100M centrifuge currently is the only deployment-ready U.S. uranium enrichment technology that can meet these national security requirements, albeit requiring one minor change in sourcing of materials.

Centrus is working to pioneer U.S. production of High-Assay, Low-Enriched Uranium (“HALEU”), enabling the deployment of a new generation of HALEU-fueled reactors to meet the world’s growing need for carbon-free power. HALEU is a high-performance nuclear fuel component which is expected to be required by a number of advanced reactor and fuel designs that are now under development for commercial and government uses. While existing reactors typically operate on LEU with the uranium-235 isotope concentration below 5%, HALEU is further enriched so that the uranium-235 concentration is between 5% and 20%. The higher U-235 concentration offers a number of potential advantages, which may include better fuel utilization, improved performance, fewer refueling outages, simpler reactor designs, reduced waste volumes, and greater nonproliferation resistance.

The lack of a domestic HALEU supply is widely viewed as a major obstacle to the successful commercialization of these new reactors. As the only company with a license from the Nuclear Regulatory Commission (“NRC”) to enrich up to 20% uranium-235 assay HALEU, Centrus is uniquely positioned to fill a critical gap in the supply chain and facilitate the deployment of these promising next-generation reactors.

The DOE has experienced a COVID-19 related supply chain delay in obtaining the HALEU storage cylinders. Since it is not possible to begin HALEU production without the storage cylinders, it would not be possible to complete the operational portion of the demonstration before the June 1, 2022 expiration date of the existing contract. As a result, the DOE elected to change the scope of the existing contract and move the operational portion of the demonstration to a new, competitively-awarded, contract that would provide for operations beyond the term of the existing contract. On February 7, 2022, the DOE issued a pre-solicitation notice for a request for proposal to complete the HALEU demonstration facility and to produce HALEU, noting that the “the Administration supports longer-term demonstration of production capability.” The pre-solicitation notice outlines a two-phase approach. Phase 1 consists of completing installation of the centrifuges – which DOE expects will take up to one year from contract signing – followed by one full year of cascade operations. Phase 2 consists of three optional, 3-year extensions to produce HALEU, so that the prospective contract could help support a total of one to ten years of cascade operations in addition to completing construction and centrifuge installation.

Centrus believes it is well-positioned to compete for a follow-on contract to operate the machines in our facility near Piketon but there is no assurance that DOE will award such a contract to the Company. Congress has not yet adopted a Fiscal Year 2022 appropriations bill for the DOE, and there is no assurance that the proposed program will be approved and funded.

The U.S. government has been operating under a series of continuing resolutions in Fiscal Year 2022. The DOE continues to support the HALEU program during the continuing resolution period, and has incrementally increased the government’s cost share ceiling as funds have become available.

Additional COVID-19-related impacts, delays in DOE furnishing equipment, or changes to the existing scope of the HALEU Contract could result in further material increases to our estimate of the costs required to complete the existing HALEU Contract, and delay completion of the contract. The Company currently does not have a contractual obligation to perform work in excess of the funding provided by DOE and, therefore, no additional costs

6

have been accrued as of December 31, 2021. If DOE does not commit to fully fund the additional costs, and the Company nevertheless commits to a plan to complete the remaining activities of the HALEU Contract, we may incur material additional costs or losses in future periods that could have an adverse impact on our financial condition and liquidity.

We believe our investment in HALEU technology will position the Company to meet the needs of government and commercial customers in the future as they deploy advanced reactors and next generation fuels. At present, there are a number of advanced reactors under development. For example, nine of the ten advanced reactor designs selected by the DOE for its Advanced Reactor Demonstration Program will require HALEU.In addition, the first non-light water reactor to begin active NRC-license review requires HALEU.The U.S. Department of Defense also plans to construct a prototype HALEU-fueled mobile microreactor in the next three to four years as part of a program called “Project Pele.”The U.S. Air Force also announced plans to deploy a microreactor at Eielson Air Force Base in Alaska.While the use of HALEU is not an express requirement of the Air Force program, the vast majority of microreactor designs are expected to need HALEU. On December 14, 2021, DOE issued a request for information related to a potential program to fund the availability of HALEU.

Advanced nuclear reactors promise to provide an important source of reliable carbon-free power. While there is no commercial market for HALEU today, we believe that by investing in HALEU technology now, and as the only American-based company currently pursuing HALEU enrichment capability and possessing an NRC license for such production, the Company could be positioned to capitalize on a potential new market as the demand for HALEU-based fuels increases in the mid to late-2020s with the development of advanced reactors. However, there are no guarantees about whether or when government or commercial demand for HALEU will materialize, and there are a number of technical, regulatory, and economic hurdles that must be overcome for these fuels and reactors to come to the market. Also, foreign government-owned and operated competitors could seek to enter the market and offer HALEU at more competitive prices. There is one known foreign government-owned entity which currently has the capability to produce HALEU, although this entity is currently subject to trade restrictions that limit the amount of material from this source which may be imported into the United States. Other foreign government owned entities which are not currently subject to U.S. trade restrictions, however, may enter the market. One such foreign government owned entity has expressed an interest in and potential capability for HALEU production but has not committed publicly to enter the market to enrich above 10% uranium-235 enrichment assays. This entity has indicated publicly that it would take six to seven years to be able to produce HALEU.

For further details, refer to Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations - Market Conditions and Outlook. For a discussion of the potential risks and uncertainties facing our business, see Part I, Item 1A, Risk Factors.

Low Enriched Uranium

LEU consists of two components: separative work units (“SWU”) and natural uranium. Revenue from our LEU segment is derived primarily from:

•sales of the SWU component of LEU,

•sales of both the SWU and natural uranium components of LEU, and

•sales of natural uranium.

Our LEU segment accounted for approximately 62% of our total revenue in 2021. Our customers are primarily domestic and international utilities that operate nuclear power plants. Our agreements with electric utilities are primarily medium and long-term, fixed-commitment contracts under which our customers are obligated to purchase a specified quantity of the SWU component of LEU from us. Our agreements for natural uranium and enriched uranium product sales, where we sell both the SWU and uranium component of LEU, are generally shorter-term, fixed-commitment contracts.

Uranium and Enrichment

Uranium is a naturally occurring element and is mined from deposits located in Kazakhstan, Canada, Australia, and several other countries, including the United States. According to the World Nuclear Association (“WNA”), there are adequate measured resources of natural uranium to fuel nuclear power at current usage rates for about 90 years. In its natural state, uranium is principally comprised of two isotopes: uranium-235 (“U235”) and uranium-238 (“U238”). The concentration of U235 in natural uranium is only 0.711% by weight. Uranium enrichment is the process by which the concentration of U235 is increased. Most commercial nuclear power reactors require LEU fuel with a U235 concentration greater than natural uranium of up to 5% by weight. Future reactor designs currently under development will likely require higher U235 concentration levels of up to 20%.

SWU is a standard unit of measurement that represents the effort required to sort natural uranium between enriched uranium having a higher percentage of U235 and depleted uranium having a lower percentage of U235. The SWU contained in LEU is calculated using an industry standard formula based on the physics of enrichment. The amount of enrichment deemed to be contained in LEU under this formula is commonly referred to as its SWU component and the quantity of natural uranium deemed to be contained in LEU under this formula is referred to as its uranium or “feed” component.

While in some cases customers purchase both the SWU and uranium components of LEU from us, utility customers typically provide the natural uranium to us as part of their enrichment contracts and in exchange we deliver LEU to these customers and charge for the SWU component. Title to natural uranium provided by customers generally remains with the customer until Centrus delivers the LEU, at which time title to LEU is transferred to the customer, and Centrus takes title to the natural uranium.

The following outlines the steps for converting natural uranium into LEU fuel, commonly known as the nuclear fuel cycle:

Mining and Milling. Natural, or unenriched, uranium is removed from the earth in the form of ore and then crushed and concentrated.

Conversion. Uranium concentrates (“U3O8”) are combined with fluorine gas to produce uranium hexafluoride (“UF6”), a solid at room temperature and a gas when heated. UF6 is shipped to an enrichment plant.

Enrichment. UF6 is enriched in a process that increases the concentration of the U235 isotope in the UF6 from its natural state of 0.711% up to 5%, or LEU, which is usable as a fuel for current light water commercial nuclear power reactors. Future commercial reactor designs may use uranium enriched up to 20% U235, or HALEU.

Fuel Fabrication. LEU is then converted to uranium oxide and formed into small ceramic pellets by fabricators. The pellets are loaded into metal tubes that form fuel assemblies, which are shipped to nuclear power plants. As the advanced reactor market develops, HALEU may be converted to uranium oxide, metal, chloride or fluoride salts, or other forms and loaded into a variety of fuel assembly types optimized for the specific reactor design.

Nuclear Power Plant. The fuel assemblies are loaded into nuclear reactors to create energy from a controlled chain reaction. Nuclear power plants generate approximately 20% of U.S. electricity and 10% of the world’s electricity.

Used Fuel Storage. After the nuclear fuel has been in a reactor for several years its efficiency is reduced and the assembly is removed from the reactor’s core. The used fuel is warm and radioactive and is kept in a deep pool of water for several years. Many utilities have elected to then move the used fuel into steel or concrete and steel casks for interim storage.

LEU Segment Order Book

Our order book of sales under contract in the LEU segment (“order book”) extends to 2029. For the years ended December 31, 2021 and 2020, our order book was approximately $986 million and $960 million, respectively. The order book is the estimated aggregate dollar amount of revenue for future SWU and uranium deliveries, and includes approximately $348.2 million of deferred revenue and advances from customers as of December 31, 2021, whereby customers have made advance payments to be applied against future deliveries. We estimate that approximately 3% of our order book is at risk related to customer operations.

Most of our customer contracts provide for fixed purchases of SWU during a given year. Our order book estimate is based partially on customers’ estimates of the timing and size of their fuel requirements and other assumptions that are subject to change. For example, depending on the terms of specific contracts, the customer may be able to increase or decrease the quantity delivered within an agreed range. Our order book estimate is also based on our estimates of selling prices, which may be subject to change. For example, depending on the terms of specific contracts, prices may be adjusted based on escalation using a general inflation index, published SWU price indicators prevailing at the time of delivery, and other factors, all of which are variable. We use external composite forecasts of future market prices and inflation rates in our pricing estimates. Refer to Part I, Item 1A, Risk Factors, for a discussion of risks related to our order book.

Suppliers

We have a diverse base of supply that includes:

•existing inventory of LEU (refer to Note 4, Inventories),

•mid-term and long-term contracts with enrichment producers,

•purchases and loans from secondary sources including fabricators and utility operators of nuclear power plants that have excess inventory, and

•spot purchases of SWU, uranium and LEU.

We aim to continue to further diversify this base of supply and take advantage of opportunities to obtain additional short and long-term supplies of LEU. Currently, our largest suppliers of SWU are TENEX and the French government owned company Orano Cycle (“Orano”).

Under the TENEX Supply Contract, we purchase SWU contained in LEU, and we deliver natural uranium to TENEX for the LEU’s uranium component. The TENEX Supply Contract extends through 2028. We typically pay for the SWU contained in the LEU, and supply natural uranium to TENEX for the natural uranium component. SWU pricing is determined by a formula that uses a combination of market-related price points and other factors. The LEU that we obtain from TENEX under the TENEX Supply Contract currently is subject to quotas and other restrictions under an agreement between the United States and the Russian Federation governing exports of Russian uranium products to the United States (the “RSA”). This agreement extends through 2040 under an amendment signed in October 2020 by the DOC and the Russian State Atomic Energy Corporation (“ROSATOM”).The October 2020 amendment provides quotas for shipments of Russian uranium products to the United States after 2020, and allocates a substantial portion of the quotas through 2028 to Centrus for use under the TENEX Supply Contract to supply LEU for use in U.S. reactors. These quotas will allow us to continue to supply Russian LEU to our U.S. customers through 2028. The terms of the RSA, as extended, were also adopted into law by the U.S. Congress in the Consolidated Appropriations Act, 2021. Refer to Item 1A Risk Factors - Operational Risks for further discussion.

9

The amount of SWU we must purchase from TENEX under the TENEX Supply Contract exceeds our current sales order book and, therefore, we will need to make new sales to place all the Russian LEU we must order to meet our SWU purchase obligations to TENEX. Although the quotas cover most of the LEU that we must order to fulfill our purchase obligations under the TENEX Supply Contract, we expect that a small portion of the Russian LEU that we order during the term of the TENEX Supply Contract will need to be delivered to customers who will use it in non-U.S. reactors.

We also have an agreement with Orano (the “Orano Supply Agreement”) for the long-term supply of SWU contained in LEU, commencing in 2023. Under the Orano Supply Agreement, we will purchase SWU contained in LEU received from Orano, and then deliver natural uranium to Orano for the natural uranium feed material component of LEU. We had the option to extend the six-year purchase period for an additional two years and have recently elected to take the additional supply in 2029. The Orano Supply Agreement provides flexibility to adjust purchase volumes, subject to annual minimums and maximums, in fixed amounts that vary year by year. The pricing for the purchased SWU is determined by a formula that uses a combination of market-related price points and other factors, and is subject to certain floors and ceilings. Prices are payable in a combination of U.S. dollars and euros.

We procure LEU from other sources under short-term and long-term contracts and have inventories available that diversify our supply portfolio and provide flexibility to help us meet the needs of our customers. We also have agreements to borrow SWU which we can use to optimize our purchases and deliveries over time.

Market prices for SWU fell substantially in the aftermath of the nuclear incident at Fukushima, Japan in 2011, bottoming out in August of 2018. While prices have been rising, they are still lower than market prices prior to Fukushima. Recent purchases of SWU and our long-term contract with Orano reflect these lower market prices. Additionally, prices under the TENEX Supply Contract have been adjusted to reflect lower market prices based on a one-time market related price reset that was agreed to when we signed the contract in 2011. The reset occurred in 2018, reducing the unit cost per SWU for our purchases from 2019 through 2028.

Technical Solutions

Our technical solutions segment reflects our technical, manufacturing, engineering, and operations services offered to public and private sector customers, including the American Centrifuge engineering, procurement, construction, manufacturing and operations services being performed under the HALEU Contract. With our private sector customers, we seek to leverage our domestic enrichment experience, engineering know-how and precision manufacturing facility to assist customers with a range of engineering, design and advanced manufacturing projects, including the production of fuel for next-generation nuclear reactors and the development of related facilities.

Government Contracting

On October 31, 2019, we signed the cost-share HALEU Contract with DOE to deploy a cascade of centrifuges to demonstrate production of HALEU for advanced reactors. The three-year program has been under way since May 31, 2019, when the Company and DOE signed an interim HALEU letter agreement that allowed work to begin while the full contract was being finalized. We have significantly invested in advanced technology because of the potential for future growth into new areas of business for the Company, while also preserving our unique workforce at our Technology and Manufacturing Center in Oak Ridge, Tennessee, and our production facility near Piketon, Ohio. The Company entered into this cost-share contract with DOE as a critical first step on the road back to the commercial production of enriched uranium, which the Company had terminated in 2013 with the closure of the Paducah GDP. The HALEU Contract, if fully implemented, is expected to result in the Company having readied the 16-machine cascade to enrich uranium to the 20% concentration in the uranium-235 isotope that is required by many of the advanced reactor concepts now under development. Centrus is currently the only company with an NRC license to enrich uranium up to the 20% concentration that is contained in HALEU.

In 2019, under the HALEU Contract, DOE agreed to reimburse the Company for 80% of its costs incurred in performing the contract, up to a maximum of $115 million (which was recently increased to $126.7 million, as noted below). The Company’s cost share is the corresponding 20% and any costs the Company elects to incur above these amounts. Costs under the HALEU Contract include program costs, including internal labor, third-party services and materials, and associated indirect costs that are classified as Cost of Sales, and an allocation of corporate costs supporting the program that are classified as Selling, General and Administrative Expenses. Services to be provided over the three-year contract include constructing and assembling centrifuge machines and related infrastructure, and training and qualifying the workforce for operation of the facility. When estimates of total costs for such an integrated, construction-type contract exceed estimates of total revenue to be earned, a provision for the remaining loss on the contract is recorded to Cost of Sales in the period the loss is determined. Our corporate costs supporting the program are recognized as expense, as incurred over the duration of the contract term. The accrued loss on the contract is being adjusted over the remaining contract term based on actual results, remaining program cost projections, and the Company’s anticipated cost-share.

Further, while we still anticipate completing construction of the cascade in 2022, due to a COVID-19 related supply chain delay in the DOE-supplied HALEU storage cylinders, production will commence under another contract that the DOE plans to compete later this year. The U.S. government has been operating under a series of continuing resolutions in Fiscal Year 2022. The DOE continues to support the HALEU program during the continuing resolution period, and has incrementally increased the government’s cost share ceiling as funds have become available. Currently, DOE has provided incremental funding, and increased the government’s cost share ceiling to $126.7 million. For further discussion, refer to Item 7, Management Discussion and Analysis, of this 10-K report.

Our HALEU Contract expires June 1, 2022, and although we believe demand for HALEU will emerge over the next several years, there are no guarantees about whether or when government or commercial demand for HALEU will materialize, and there are a number of technical, regulatory and economic hurdles that must be overcome for these fuels and reactors to come to the market.

Commercial Contracting

In 2018, we entered into two services agreements with X-energy to provide technical and resource support for the conceptual and preliminary design of its Tri-Structural Isotropic (“TRISO”) fuel manufacturing process. Both of these contracts have been completed. In August 2021, we entered into a new services agreement with X-energy to provide design services for detailed design of the TRISO fuel manufacturing facility and various support services for establishing their TRISO Research and Development Center. The task orders under the new agreement may include in-kind contributions that we are not currently, but may provide, at our discretion.

Competition and Foreign Trade

It is estimated that the enrichment industry market for commercial nuclear reactors powered by low enriched uranium (“LEU”) is currently about 57.5 million SWU per year. Our global market share of enrichment for the LEU market is less than 5%. Global LEU suppliers in our highly competitive industry compete on the basis of price and reliability of supply. The four largest LEU suppliers comprise over 95% of market share combined:

•ROSATOM, a Russian government entity, which sells LEU through its wholly-owned subsidiary TENEX;

•Urenco, a consortium of companies owned or controlled by the British and Dutch governments and two German utilities;

•Orano, a company largely owned by the French government that was formerly part of the French government; and

•China Nuclear Energy Industry Corporation (“CNEIC”), a company owned by the Chinese government.

The production capacity for ROSATOM/TENEX is estimated by the World Nuclear Association to be approximately 28.7 million SWU per year. Imports of LEU and other uranium products produced in the Russian Federation are subject to restrictions as described below under — Russian Suspension Agreement.

Urenco reported installed capacity at its European and U.S. enrichment facilities of 19.6 million SWU per year at the end of 2020.

Orano’s gas centrifuge enrichment plant in France began commercial operations in 2011 and the plant’s nominal capacity of 7.5 million SWU was reportedly in service at the end of 2016. Orano has reported that it has suspended planned capacity expansions beyond 7.5 million SWU.

CNEIC has emerged as a significant producer primarily focused on supplying domestic requirements in China. CNEIC’s commercial SWU production capacity is estimated to be approximately 10.7 million SWU per year in 2020.

All of our current competitors are owned or controlled, in whole or in part, by foreign governments, and operate enrichment technologies developed with the financial support of foreign governments. These competitors may make business decisions in both domestic and international markets that are influenced by political or economic policy considerations rather than exclusively by commercial considerations.

LEU also may be produced by down-blending government stockpiles of highly-enriched uranium. Governments control the timing and availability of highly-enriched uranium released for this purpose, and the release of this material to the market could impact market conditions. Given the current oversupplied nuclear fuel market, any additional LEU from down-blended highly-enriched uranium released into the market would have a negative effect on prices for LEU.

Our LEU supply to foreign customers is exported under the terms of international agreements governing nuclear cooperation between the United States and the government of the country of destination or other entities, such as the European Union or the International Atomic Energy Agency. The LEU supplied to us is subject to the terms of cooperation agreements between the country in which the material is produced and the country of destination or other entities.

Russian Suspension Agreement

Imports into the United States of LEU and other uranium products produced in the Russian Federation, including LEU imported by Centrus under the TENEX Supply Contract, are subject, through December 31, 2040, to quotas imposed under U.S. legislation enacted into law in September 2008 and December 2020, and under the RSA, as amended in 2008 and 2020. These quotas limit the amount of Russian LEU that can be imported into the United States for U.S. consumption1.

The RSA is a trade agreement between the DOC and the Russian State Atomic Energy Corporation (“ROSATOM”) originally signed in 1992 suspended an anti-dumping duty investigation of Russian uranium, and imposed quantitative limits on exports of Russian uranium products, including LEU, to the United States. Under an amendment signed on October 5, 2020, the RSA’s limits on shipments of Russian uranium product to the United States were extended through at least 2040. Additionally, under legislation passed by the U.S. Congress shortly after the amendment was signed, the material terms of the extended RSA were enacted into law.

Under this law and the RSA, imports of Russian uranium products will peak in 2023 at 24% of the forecasted U.S. demand for enrichment and then begin to decline, reaching 15% by 2028. Despite the fact that overall limits will ramp down, the RSA extension agreement explicitly sets aside sufficient quota in 2021-2028 for Centrus. The RSA and the legislation provide for a revision of the quotas in 2023, 2029, and 2035 to take account of SWU demand forecasts that will be published by the WNA in the future. Any quota adjustment or other change to the RSA could affect our ability to implement the TENEX Supply Contract through sales to customers who take delivery in the United States, which is our most significant market.

The actual size of the annual quotas allocated to Centrus for the TENEX Supply Contract are confidential, but a public version of the quotas shows that they represent a significant portion of the total quotas provided under the RSA in 2021-2028. The quotas provided for the TENEX Supply Contract are expected to be adequate to support the Company’s long-term strategic goals and to permit enriched uranium procured from TENEX during the remaining term of the TENEX Supply Contract to be imported to supply U.S. utilities, thereby securing a key part of the Company’s supply base for the benefit of its customers and providing the revenues needed by the Company to support its work on HALEU and other advanced technology projects in the United States.

For further details, refer to Part I, Item 1A, Risk Factors - Our future prospects are tied directly to the nuclear energy industry worldwide, and the financial difficulties experienced by, and operating conditions of, our customers and suppliers could adversely affect our results of operations and financial condition.

Other Actions Adversely Affecting International Trade

In 2018, in connection with the withdrawal by the United States from a 2015 multilateral agreement known as the Joint Comprehensive Plan of Action (“JCPOA”) the U.S. government re-imposed sanctions on Iran’s Atomic Energy Organization of Iran (“AEOI”) and a number of its subsidiaries. Waivers were granted to allow non-Iranian entities to continue to work on certain programs that, among other things, allowed affiliates of ROSATOM to continue work on nuclear projects in Iran. These waivers have expired or been terminated and as a result, the U.S. government could decide to impose sanctions on Russian entities that may be involved in nuclear work in Iran, including ROSATOM or its subsidiaries. These sanctions could affect companies owned by ROSATOM, including TENEX, even if they are not doing work in Iran. To date, no sanctions have been imposed or announced on TENEX or any other ROSATOM subsidiary involved in the TENEX Supply Contract, in respect to the work of ROSATOM or its subsidiaries in Iran.

1 The term “quota” is used herein for simplicity. The amounts of Russian uranium products that can be shipped to the United States are referred to as export limits in the RSA and import limits in the legislation, but from a practical perspective have identical effect.

DOE Facilities

We produced LEU through 2001 at the former Portsmouth Gaseous Diffusion Plant (“Portsmouth GDP”) in Piketon, Ohio and through 2013 at the former Paducah GDP in Paducah, Kentucky, which we had leased from DOE. We currently store our existing inventory at third-party offsite licensed locations under agreements with the operators of those facilities. The Portsmouth GDP and Paducah GDP were operated by agencies of the U.S. government for more than 40 years prior to the creation of the Company through privatization of the Government enterprise in 1998. As a result of such operation, there are contamination and other potential environmental liabilities associated with the Government’s prior operation of the plants. The USEC Privatization Act and our former leases for the plants provide that DOE remains responsible for the decontamination and decommissioning (“D&D”) of the gaseous diffusion plants. Further, DOE continued operations as well as cleanup activities, both during and subsequent, to our operations at the facilities.

We lease facilities and related personal property near Piketon, Ohio from DOE. In connection with a letter agreement that preceded the HALEU Contract, DOE and Centrus amended the lease agreement, which was scheduled to expire by its terms on June 30, 2019. The lease was extended until May 31, 2022. In September 2021, the Company and the DOE renewed and extended the lease until December 31, 2025. Any facilities or equipment constructed or installed under the HALEU Contract, or other contract with DOE will be owned by DOE and may be returned to DOE in an “as is” condition at the end of the lease term. DOE will be responsible for the D&D of any returned facilities or equipment. If we determine the equipment and facilities may benefit Centrus after completion of the HALEU program, we can extend the facility lease and ownership of the equipment will be transferred to us, subject to mutual agreement regarding D&D and other issues, including those impacted by DOE’s recent decision to competitively award a separate contract for operations of the HALEU cascade following the expiration of our HALEU Contract, which may be awarded to a third party.

Item 1A. Risk Factors

The following discussion sets forth the material risk factors that could affect our financial condition and operations. Readers should not consider any descriptions to be a complete set of all potential risks that could affect us.

War in Ukraine

The current war in Ukraine has led to the U.S., Russia and other countries imposing sanctions and other measures that restrict international trade. The situation is rapidly changing, and it is not possible to predict future actions that could be taken. The Company has multiple sources of supply; however, the supply contract with Tenex remains our largest source. At present, sanctions have not impacted the ability of the Company or TENEX to perform under the TENEX supply contract. Recently sanctions have been imposed by the U.S. on exports of fossil fuels. Russia has imposed sanctions on the export of commodities but does not include the export of LEU. Additional sanctions or other measures by the U.S. or foreign governments (including the Russian government) could be imposed. Any sanctions or measures directed at trade in LEU from Russia or the parties involved in such trade or otherwise could interfere with, or prevent, implementation of the TENEX Supply Contract. While the initial sanctions announced do not affect the ability of the Company or TENEX to implement the TENEX Supply Contract, the situation at this time is unpredictable and therefore there is no assurance that future developments would not have a material adverse effect on the Company’s procurement, payment, delivery or sale of LEU under the TENEX Supply Contract.

If measures were taken to limit the supply of Russian LEU or to prohibit or limit dealings with Russian entities, including, but not limited to, TENEX or ROSATOM, the Company would seek a license, waiver or other approval from the government imposing such measures to ensure that the Company could continue to fulfill its purchase and sales obligations. There is no assurance that such a license, waiver, or approval would be granted. If a license, waiver or approval were not granted, the Company would need to look to alternative sources of LEU to replace the LEU that it could not procure from TENEX. The Company has contracts for alternative sources that could be used to mitigate a portion of the near term impacts. However, to the extent these sources were insufficient or more expensive or additional supply cannot be obtained, it could have a material adverse impact on our business, results of operations, and competitive position.

Economic and Industry Risks

Our future prospects are tied directly to the nuclear energy industry worldwide, and the financial difficulties experienced by, and operating conditions of, our customers and suppliers could adversely affect our results of operations and financial condition.

Potential events that could affect either our customers or suppliers under current or future contracts with us or the nuclear industry as a whole, include:

•pandemics, armed conflicts (including the war in Ukraine), government actions and other events that disrupt supply chains, production, transportation, payments and importation of nuclear materials or other critical supplies or services;

•natural or other disasters (such as the 2011 Fukushima disaster) impacting nuclear facilities or involving shipments of nuclear materials;

•changes in U.S. or foreign government policies and priorities;

•regulatory actions or changes in regulations by nuclear regulatory bodies applicable to us, our suppliers or our customers;

•decisions by agencies, courts or other bodies under applicable trade and other laws applicable to us, our suppliers or our customers;

•disruptions in other areas of the nuclear fuel cycle, such as uranium supplies or conversion;

•civic opposition to, or changes in government policies regarding, nuclear operations;

•business decisions concerning reactors or reactor operations;

19

•the financial condition of reactor owners and operations;

•the need for generating capacity; or

•consolidation within the electric power industry.

These events could adversely affect us to the extent they result in a reduction or elimination of customers’ contractual requirements to purchase from us; the suspension or reduction of nuclear reactor operations; the reduction or blocking of supplies of raw materials, natural or enriched uranium or separative work units (SWU), lower demand, burdensome regulation, disruptions of shipments, production importation or payment (including the blocking or restriction of transportation services or hardware); increased competition from third parties; and increased costs or difficulties or increased liability for actual or threatened property damage or personal injury. Additionally, customers may face financial difficulties, including from factors unrelated to the nuclear industry, that could affect their willingness or ability to make purchases. We cannot provide any assurance that events will not preclude us from making deliveries to our customers, increase our costs or that our customers, suppliers, or contractors will not default on their obligations to us or file for bankruptcy protection. If a customer files for bankruptcy protection, for example, we likely would be unable to collect all, or even a significant portion, of amounts that are owed to us. A default and bankruptcy filing by one or more customers or suppliers, or events (such as government actions) which prevent or limit our ability to obtain or sell material or services, could have a material adverse effect on our business, financial position, results of operations, or cash flows.

Our business, financial and operating performance could be adversely affected by epidemics and other health related issues including but not limited to the coronavirus disease 2019 (“COVID-19”) pandemic.

The global outbreak of COVID-19 was declared a pandemic by the World Health Organization and a national emergency by the U.S. Government and has negatively affected the U.S. and global economies, disrupted supply chains, and has resulted in significant travel, transport, and other restrictions. The COVID-19 outbreak has disrupted the supply chains and day-to-day operations of the Company, our suppliers, our contractors, and our customers, which could materially adversely affect our operations. In this regard, global supply chains and the timely availability of products or product components sourced domestically or imported from other nations, including SWU contained in LEU we purchase, could be materially disrupted by quarantines, slowdowns or shutdowns, border closings, and travel restrictions resulting from the global COVID-19 pandemic or other global pandemic or health crises. Further, impacts of COVID-19 infections and other COVID-19 pandemic related impacts on our management and workforce, or our suppliers, contractors, or customers, could adversely impact our business. While we have taken steps to protect our workforce and carry on operations, we may not be able to mitigate all of the potential impacts. We anticipate increased costs related to, or resulting from, the COVID-19 pandemic, due to, among other things, delays in supplier deliveries, impacts of travel restrictions, site access and quarantine requirements, and the impacts of remote work and adjusted work schedules.

The impacts of the COVID-19 pandemic have been primarily affecting our technical solutions segment since much of the work required under the HALEU Contract must be performed on the Company’s sites and on our suppliers’ sites. As a result, our costs under the HALEU Contract have been impacted. Further, as a result of the U.S. Department of Energy (“DOE”) not supplying us cylinders as required under the HALEU Contract, operation of the cascade has been deferred and will be performed under a subsequent competitively bid contract that may or may not be awarded to us.

In the event that the COVID-19 pandemic prevents our employees or our contractors from working in-person at our site or, our suppliers are unable to provide goods and services on the schedule we anticipated, the impacts on our schedule and costs could be material. Again, while we have worked to mitigate the impact, we are experiencing increased costs as the result of the impact of the pandemic on their operations.

We continue to work with our customers, employees, contractors, suppliers and communities to address the impacts of the COVID-19 pandemic and to take actions in an effort to mitigate adverse consequences. However, the ultimate impact of the COVID-19 pandemic on our operations and financial performance in future periods,

20

including our ability to execute our strategic plan and programs in the expected timeframe, remains uncertain and will depend on future pandemic related developments, including the duration of the pandemic and any potential subsequent variants of COVID-19 and related government actions to prevent and manage disease spread, all of which are uncertain and cannot be predicted. The long-term impacts of the COVID-19 pandemic on us or on government budgets, our customers, contractors and suppliers that could impact our business are also difficult to predict but could adversely affect our business, results of operations, and prospects.

The continued excess supply of LEU in the market could adversely affect market prices and our business results.

Events related to the March 2011 earthquake and tsunami that caused irreparable damage to four reactors in Fukushima, Japan created an over-supply of nuclear fuel that continues to heavily influence market prices. In addition, reactor operators facing aggressive price competition from natural gas and subsidized renewable generation like wind and solar, have closed or are planning to close reactors, further reducing demand for our product and services. Despite the decrease in demand, some of our competitors supported by foreign governments continued to expand their capacity. Market uncertainty, and reduced demand, coupled with excess capacity and supply has adversely affected our ability to sell LEU and SWU and could adversely affect our business, results of operations, and prospects.

Our business is exposed to price volatility associated the procurement of SWU and uranium.

The Company is exposed to commodity price risk for purchases of SWU and uranium. Our earnings and cash flows are therefore exposed to variability of spot and forward market prices in the markets in which it operates. The supply markets for SWU and uranium are subject to price fluctuations and availability restrictions.

Operational Risks

Restrictions on imports or sales of SWU or uranium that we buy from our Russian supplier and our other sources of supply could adversely affect profitability and the viability of our business.

The majority of the SWU and LEU that we use to fill existing contracts with customers is sourced from outside the United States, including from Russia under the TENEX Supply Agreement, and we expect the arrangement to continue into the future. Our ability to place this SWU and LEU into existing and future contracts with customers is subject to trade restrictions, sanctions, and other limitations imposed by the United States and other governments and our customers. For example, our imports from Russia are subject to U.S. quotas. Given the quotas, restrictions, and customer limitations that limit our ability to sell SWU and LEU purchased under the TENEX Supply Agreement both in the United States and globally, there is no guarantee that we can make sufficient sales to meet our minimum purchase obligation under the TENEX Supply Agreement. (For further information refer to Part I, Item 1, Competition and Foreign Trade).

Further, currently evolving international events, including the war in Ukraine could result in new or additional sanctions or other U.S. or foreign government actions that could directly or indirectly limit or prevent our purchase, importation, or ability to sell material under our TENEX Supply Agreement. Even absent such restrictions, some of our U.S. and foreign customers are unable or unwilling to accept Russian SWU and uranium.

Geopolitical events, including domestic or international reactions or responses to such events, as well as concerns about national security or other issues, also could lead to U.S. or foreign government or international actions that could disrupt our ability to purchase, sell, or make deliveries of LEU, SWU, or other uranium products, or even to continue to do business with one or more of our suppliers or their affiliates. Our inability to meet our purchase or sales obligations, or to earn revenues from U.S. and international sales, would adversely affect our financial condition, results of operations, cash flows, and the viability of our business. All of these outcomes, individually and collectively, could cause us to incur significant financial losses, in addition to impeding or preventing us from fulfilling our existing contracts, or winning new contracts, and could adversely affect our profitability and the viability of our business.

21

We may be unable to sell all of the LEU we are required to purchase under supply agreements for prices that cover our costs, which could adversely affect profitability and the viability of our business.

We may not achieve the anticipated benefits from supply agreements we enter into. The prices we are charged under some supply agreements are determined by formulas that may not be aligned with the prevailing market prices at the time we enter into contracts with customers. As a result, the sales prices in our contracts may not cover our purchase costs, or those purchase costs may limit our ability to secure profitable sales.

We are dependent on purchases from our suppliers and other sources to meet our obligations to customers and rely on third parties to provide essential services.

We are currently dependent on purchases from suppliers to meet our obligations to customers, including purchases from the Russian government entity, TENEX. A significant delay in, or stoppage or termination of, deliveries of material to us under our supply agreements, could adversely affect our ability to make deliveries to customers. The recent action of Russian military forces in Ukraine has escalated tensions between Russia and the U.S. The U.S. has imposed, and is likely to impose additional, financial and economic sanctions and export controls against certain Russian organizations and/or individuals. Sanctions and export controls, as well as any actions by Russia, could adversely affect our supply and our ability to meet our obligations to customers.

We also rely on third parties to provide essential services to the Company, such as the storage and management of inventory, transportation, and radiation protection. Those service providers may not perform on time, with the desired quality, or at all for a variety of reasons, many of which are outside our control. An interruption of deliveries from our suppliers or the provision of essential services by third parties, could adversely impact our business, results of operations, and prospects.

We face significant competition from major producers who may be less cost sensitive or may be favored due to support from foreign governments.

We compete with major producers of LEU, all of which are wholly or substantially owned by governments: Orano (France), Rosatom/TENEX (Russia), Urenco (the Netherlands, the United Kingdom and two German utilities), and CNEIC (China). Our competitors have greater financial resources than we do. Foreign competitors enjoy financial and other support from their government owners, which may enable them to be less cost or profit-sensitive than we are. In addition, decisions by foreign competitors may be influenced by political and economic policy considerations rather than commercial considerations. For example, foreign competitors may elect to increase their production or exports of LEU, SWU, or other uranium products, including HALEU, even when not justified by market conditions, thereby depressing prices and reducing demand for our LEU, SWU, and other uranium products. This could adversely affect our business, results of operations, and prospects. Moreover, our competitors may be better positioned to take advantage of improved market conditions and increase capacity to meet any future market expansion.

The ability to compete in certain foreign markets may be limited for legal, political, economic or other reasons.

Doing business in foreign markets poses additional risks and challenges. For example, agreements for cooperation between the U.S. government and various foreign governments or governmental agencies control the export of nuclear materials from the United States. We are unable to supply fuel for foreign reactors unless there is an agreement for cooperation in force. If an agreement with a country in which one or more of our customers is located were to lapse, terminate, or be amended, our sales or deliveries could be curtailed or terminated, adversely affecting our business, results of operations, and prospects. Moreover, the lack of such agreements for cooperation between the United States government and those governments or agencies in emerging markets may restrict our ability to sell into such markets. Additionally, countries may impose other restrictions on the import or export of material or services.

22

Purchases of LEU and SWU by customers in the European Union are subject to a policy of the Euratom Supply Agency that seeks to limit foreign enriched uranium to no more than 20% of European Union consumption per year. Similarly, China has a policy of using Chinese sources of LEU and SWU. Such policies limit our ability to sell in those countries.

Certain foreign markets lack a comprehensive nuclear liability law that protects suppliers by channeling liability for injury and property damage suffered by third persons from nuclear incidents at a nuclear facility to the facility’s operator. The lack of legal protection for suppliers could adversely affect our ability to compete for sales to meet the growing demand for LEU or SWU in these markets and our prospects for future revenue from such sales.

Dependence on our largest customers could adversely affect us.

In 2021, our ten largest nuclear fuel customers represented approximately 57% of total revenue and our two largest customers represented approximately 24% of total revenue. Further, individual orders average $7.4 million. A reduction in purchases from our customers, whether due to their decision not to purchase optional quantities or for other reasons, including a disruption or change in their operations or financial condition that reduces purchases of LEU, SWU, or other uranium products from us, could adversely affect our business, results of operations, and prospects. Once lost, customers may be difficult to regain because they typically purchase under long-term contracts. Consequently, we may face reduced revenues and difficulty in selling the material we are obligated to buy, which could adversely affect our business, results of operations, and prospects.

The dollar amount of the sales order book, as stated at any given time, is not necessarily indicative of future sales revenues and is subject to uncertainty.

Our order book of sales is the estimated aggregate dollar amount of SWU and uranium sales that we expect to recognize as revenue in future periods under existing contracts with customers. It includes deferred revenue for sales in which we have been paid but still have a delivery obligation, which means we will not receive cash in the future from those deliveries. There is no assurance that the revenues projected will be realized, or, if realized, will result in profits. Our estimate of the order book is based on a number of factors including customers’ estimates of the timing and size of their fuel requirements and estimates of future selling prices. For example, depending on the terms of specific contracts, prices may be adjusted based on escalation using a general inflation index, published SWU or uranium market price indicators prevailing at the time of delivery, and other factors, all of which are unpredictable. Any inaccuracy in estimates of future prices would add to the imprecision of the order book estimate. From time to time, we have worked with customers to modify contracts that have delivery, scheduling, origin or other terms that may require modifications to address our anticipated supply sources. If we were to initiate such discussions in the future, we have no assurance that our customers would agree to revise existing contracts or would not require concessions, which could adversely affect the value of our order book and our prospects.

Our ability to operate the HALEU enrichment facility we are deploying under the HALEU Contract after the completion of the deployment is dependent on our ability to secure additional contracts and funding from the U.S. government or other sources.

In 2019, Centrus began work on a three-year, cost-shared contract with the DOE to deploy a cascade of 16 of our AC100M centrifuges to demonstrate production of HALEU with domestic technology. As a result of the on-going supply chain disruptions due to the COVID-19 pandemic and other factors, DOE has been unable to provide the cylinders required to begin HALEU production under the current contract. Consequently, operation of the demonstration cascade will be performed pursuant to a separate subsequent, competitively-awarded contract which may not be awarded to us. Although we believe we are well positioned to compete for the subsequent contract to operate the cascade beginning in 2022, there is no assurance that we will be awarded such contract.

Our goal is to be in a position to begin production and scale up the facility in modular fashion as demand for HALEU grows in the commercial and/or government sectors. However, our right to operate the facility we are building depends on the award of one or more follow-on contracts by the U.S. government, as well as continued

23

funding for operation from the U.S. government or other sources. There is no assurance that we will be awarded such contracts or that such funding will be available. Further, it is uncertain whether or when demand to support the scale up of the facility will materialize. If we do not secure the necessary contracts and funding and if sufficient demand does not emerge, we may not be able to continue or expand operations at that facility and may not be able to support providing HALEU fuel for the advanced reactors under development.

If we are required to delease the facility where we are deploying the HALEU cascade under the HALEU Contract and return it, along with the centrifuges and supporting equipment, to the DOE at the expirations of our contract, this would likely result in the termination of our NRC operating license and us laying off our Piketon workforce. However, if we are able to continue operating the facility, we would incur additional costs and liabilities associated with the facility.

If the Company’s operation of the Piketon facility were terminated, there can be no assurance that we could regain use of the Piketon facility or obtain a new NRC license in the future at the Piketon site or an alternative site, in which event we would be unable to begin commercial production of HALEU. We may also incur additional costs related to reducing our workforce or closing the Piketon facility. Failure to secure U.S. government or other funding to support the continued operation of the Piketon facility, and retain our NRC license, could have a material adverse effect on our business and financial condition along with our plans for future growth.

Our technical solutions segment conducts business under various types of contracts, including fixed-price and cost-share contracts, which subjects us to risks associated with cost over-runs.

The technical solutions segment conducts business under various types of contracts, including fixed-price contracts and cost-share contracts, where costs must be estimated in advance of our performance. These types of contracts are priced, in part, on cost and scheduling estimates that are based on assumptions including prices and availability of experienced labor, equipment and materials, and estimates of the amount of other contract work we expect to perform. In the event we have cost overruns, we may not be able to obtain compensation for additional work performed or expenses incurred. Our failure to accurately estimate the resources and time required for fixed-price or cost-share contracts or our failure to complete our contractual obligations within the time frame and costs committed could result in reduced profits, greater costs, or a loss for that contract. If the cost overrun on a contract is significant, or we encounter issues that affect multiple contracts, the cost overrun could have a material adverse effect on our business, financial condition, and results of operations.

Financial Risks

We have significant long-term liabilities.

We continue to have significant long-term liabilities, including the indebtedness under our 8.25% Notes, which mature in February 2027. We also still have substantial pension and postretirement health and life benefit obligations and other long-term liabilities.

Our significant long-term liabilities (and other third-party financial obligations) could have important consequences, including:

•making it more difficult for us to satisfy our obligations to lenders and other creditors, resulting in possible defaults on, and acceleration of, such indebtedness or breaches of such other commitments;

•placing us at a competitive disadvantage by making us more vulnerable to react to adverse economic conditions or changes in the nuclear industry;

•hindering our ability to obtain additional financing for future working capital and other general corporate requirements;

•reducing our cash resources for payments on our 8.25% Notes thereby limiting our ability to fund our operations, capital expenditures, and future business opportunities;

24

•placing certain restrictions on the ability of our subsidiary, United States Enrichment Corporation (“Enrichment Corp.”), to transfer cash and other assets to us, which could constrain our ability to pay dividends on our Common Stock or to fund our commitments or the commitments of our other subsidiaries, pursuant to the indenture governing our 8.25% Notes, subject to certain exceptions; and

•restricting our ability to engage in certain mergers or acquisitions pursuant to the indenture governing our 8.25% Notes also requires us to offer to repurchase all such outstanding notes at 101% of their outstanding principal amount in the event of certain change of control events.

The terms of the indenture governing our 8.25% Notes do not restrict Centrus or any of its subsidiaries from incurring substantial additional indebtedness in the future. If we incur substantial additional indebtedness the foregoing risks would intensify, however. Additional information concerning the 8.25% Notes including the terms and conditions of the 8.25% Notes are described in Note 8, Debt of the consolidated financial statements.

The Company has material unfunded defined benefit pension plans obligations and postretirement health and life benefit obligations. Levels of returns on pension and postretirement benefit plan assets, changes in interest rates and other factors affecting the amounts to be contributed to fund future pension and postretirement benefit liabilities could adversely affect earnings and cash flows in future periods.

Centrus and its subsidiary, Enrichment Corp., maintain qualified defined benefit pension plans that are guaranteed by the Pension Benefit Guaranty Corporation (“PBGC”), a wholly-owned U.S. government corporation that was created by the Employee Retirement Income Security Act of 1974, as amended (“ERISA”). Centrus also maintains non-qualified defined benefit pension plans for certain executive officers. These plans are anticipated to require material cash contributions in the future, which may divert funds from other uses and could adversely impact our liquidity depending on the timing of any required contributions or payments in relation to our sources of cash and other payment obligations.

Further, earnings may be positively or negatively impacted by the amount of expense we record for employee benefit plans. Generally accepted accounting principles in the United States (“U.S. GAAP”) require a company to calculate expenses for these plans using actuarial valuations. The IRS and the Pension Protection Act of 2006 regulate the minimum amount we contribute to our pension plans. The amount we are required to contribute to pension plans could have an adverse effect on our cash flows.

Our revenues and operating results may fluctuate significantly from quarter to quarter and year to year, which could have an adverse effect on our cash flows.

Revenue is recognized when or as we transfer control of the promised LEU or uranium to the customer. Customer demand is affected by, among other things, electricity markets, reactor operations, maintenance, and the timing of refueling outages. As a result, a relatively small change in the timing, amount, or other terms of customer orders for LEU due to a change in a customer’s refueling schedule or other reasons may cause operating results to be substantially above or below expectations, which could have an adverse effect on our cash flows.

Results of operations could be negatively impacted if adverse conditions or changes in circumstances indicate a possible impairment loss related to our intangible assets.

Intangible assets originated from our reorganization and application of fresh start accounting as of September 30, 2014. The intangible assets represented the fair value adjustment to the assets and liabilities for our LEU segment. The intangible assets remaining on our balance sheet relate to our sales order book and customer relationships. The order book intangible asset is amortized to expense as the order book valued at emergence is reduced, principally as a result of deliveries to customers. The customer relationships intangible asset is amortized to expense using the straight-line method over the estimated average useful life of 15 years with 7 3⁄4 years of scheduled amortization remaining.

25

The carrying values of the intangible assets are subject to impairment tests whenever adverse conditions or changes in circumstances indicate a possible impairment loss. If impairment is indicated, the asset carrying value will be reduced to its fair value. Inherent in our fair value determinations are certain judgments and estimates, including projections of future cash flows, the discount rate reflecting the risk inherent in future cash flows, the interpretation of current economic indicators and market valuations, and strategic plans with regard to operations. A change in these underlying assumptions could cause the fair value of the intangible asset to be less than its respective carrying amount.

Centrus is dependent on intercompany support from Enrichment Corp.

Substantially all of our revenue-generating operations are conducted at our subsidiary, Enrichment Corp. The financing obtained from Enrichment Corp. funds our general corporate expenses, including interest payments on the 8.25% Notes, which are guaranteed on a limited and subordinated basis by Enrichment Corp. As a wholly-owned subsidiary of Centrus, Enrichment Corp. has its own set of creditors and a separate board of directors (the “Enrichment Board”), who are elected by Centrus. Current and future funding and support are conditional and dependent on Enrichment Corp.’s own financial condition and a determination by the Enrichment Board that such funding is in the interest of Enrichment Corp.

There is limited trading volume for our securities and the market price of our securities is subject to volatility.

The price of our Class A Common Stock remains subject to volatility. The market price and level of trading of our Class A Common Stock could be subject to wide fluctuations in response to numerous factors, many of which are beyond our control. These factors include, among other things, our limited trading history, our limited trading volume, the concentration of holdings of our Class A Common Stock, actual or anticipated variations in our operating results and cash flow, the nature and content of our earnings releases, announcements or events that impact our products, customers, competitors or markets, business conditions in our markets and the general state of the securities markets and the market for energy-related stocks, as well as general economic and market conditions and other factors that may affect our future results. Additionally, future sales of our common stock or instruments convertible into our common stock, in public or private offerings may depress our stock price.

Holders of our Class B Common Stock, par value $0.10 per share (“Class B Common Stock” and together with the Class A Common Stock, “Common Stock”) may make decisions regarding their investment in the Company based upon factors that are unrelated to the Company’s performance. Any sales of shares by holders of our Class B Common Stock would result in automatic conversion (with limited exceptions) of Class B Common Stock into Class A Common Stock, which in turn could adversely impact the trading price of the Class A Common Stock.

Our 8.25% Notes are not listed on any securities exchange. No assurance can be given as to the liquidity of the trading market for the 8.25% Notes. The 8.25% Notes may only be traded infrequently in transactions arranged through brokers or otherwise, and reliable market quotations for the 8.25% Notes may not be available. In addition, the trading prices of the 8.25% Notes will depend on many factors, including prevailing interest rates, the trading volumes, and the other factors discussed above with respect to the Class A Common Stock.

A small number of holders of our Class A Common Stock may exert significant influence over the direction of the Company.

As of December 31, 2021, based solely on amounts reported in Schedule 13D and 13G filings with the SEC, two stockholders with the largest holdings of our Class A Common Stock collectively own approximately 19% of our Class A Common Stock. As a result, these stockholders may be able to exert significant influence over all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions, such as a merger of the Company, or sale of substantially all of the Company’s assets. These stockholders may have interests that differ from, and may vote in a way adverse to, other holders of Class A Common Stock, or adverse to the recommendations of the Company’s management. This concentration of ownership may make it more difficult for other stockholders to effect substantial changes in the Company, may limit the ability of the Company to pass

26

certain initiatives or other items that require stockholder approval, and may also have the effect of delaying, preventing, or expediting, as the case may be, a change in control of the Company.

A small number of Class A stockholders, who also have significant holdings of the Company’s 8.25% Notes, may be motivated by interests that are not aligned with the Company’s other Class A stockholders.

Currently, a small number of persons who also are stockholders collectively own greater than 25% of our 8.25% Notes. As a result, these stockholders may have interests that differ from the remainder of the holders of our Class A Common Stock, and, as a result, may vote or take other actions in a way adverse to other holders of Class A Common Stock.

Our ability to utilize our net operating loss carryforwards to offset future taxable income may be limited.

Our ability to fully utilize our existing net operating losses (“NOLs”) or net unrealized built-in losses could be limited or eliminated in the event (i) we undergo an “ownership change” as described under Section 382 of the Internal Revenue Code, (ii) we do not reach profitability or are only marginally profitable, or (iii) there are changes in U.S. government laws and regulations. An “ownership change” is generally defined as a greater than 50% change in equity ownership by value over a rolling three-year period. Past or future ownership changes, some of which may be beyond our control, as well as differences and fluctuations in the value of our equity securities may adversely affect our ability to utilize our NOLs and could reduce our flexibility to raise capital in future equity financings or other transactions, or we may decide to pursue transactions even if they would result in an ownership change and impair our ability to use our NOLs. In addition, the “Section 382 Rights Agreement” we have adopted with respect to our common stock contains limitations on transferability intended to prevent the possibility of experiencing an “ownership change,” but we cannot be certain that these measures will be effective. We also may decide to pursue transactions even if they would result in an ownership change and impair our ability to use our NOLs. In addition, any changes to tax rules and regulations or the interpretation of tax rules and regulations could negatively impact our ability to recognize any potential benefits from our NOLs or net unrealized built-in losses.

Legal and Compliance Risks

Our operations are highly regulated by the U.S. government, including the NRC and the DOE as well as the States of Ohio and Tennessee and could be significantly impacted by changes in government policies and priorities.

Our operations, including the facilities we lease near Piketon, Ohio, are subject to regulation by the U.S Nuclear Regulatory Commission (“NRC”). The NRC has granted us two licenses for the Piketon facility: a license for a Lead Cascade test facility that was granted in February 2004, and a separate license to construct and operate a commercial plant that was granted in April 2007. Our license to construct and operate a commercial plant will expire on April 13, 2037. In June 2021, the NRC approved an amendment to permit HALEU production as a subset of the larger commercial plant license. We are currently performing work under a three-year contract with DOE for the construction of a cascade to produce HALEU. This contract is currently set to expire on June 1, 2022.

The NRC also could refuse to renew our license to construct and operate a commercial plant if it determines that: (1) we are foreign owned, controlled, or dominated; (2) the issuance of a renewed license would be inimical to the maintenance of a reliable and economic domestic source of enrichment; (3) the issuance of a renewed license would be adverse to U.S. defense or security objectives; or (4) the issuance of a renewed license is otherwise not consistent with applicable laws or regulations in effect at the time of renewal.

The NRC has the authority to issue notices of violation for violations of the Atomic Energy Act of 1954, as amended (the “Atomic Energy Act”), the NRC regulations and conditions of licenses, certificates of compliance, or orders. The NRC has the authority to impose civil penalties or additional requirements and to order cessation of operations for violations of its regulations. Penalties under the NRC regulations could include substantial fines, imposition of additional requirements, or withdrawal or suspension of licenses or certificates. Any penalties

27

imposed on us could adversely affect our results of operations and liquidity. The NRC also has the authority to issue new regulatory requirements or to change existing requirements. Changes to the regulatory requirements also could adversely affect our results of operations and financial condition.

In addition, certain of our operations are subject to DOE regulation or contractual requirements. Our facility in Oak Ridge is also regulated by the State of Tennessee under NRC’s Agreement State Program as well as applicable state laws. Our operations at the facility near Piketon also are subject to regulation by various agencies of the Ohio state government. These state and federal agencies may have the authority to impose civil penalties and additional requirements, which could adversely affect our results of operations. Further, changes in federal, state or local government policies and priorities can impact our operations and the nuclear industry. This includes changes in interpretations of regulatory requirements, increased inspection or enforcement activities, changes in budgetary priorities, changes in tax laws and regulations and other actions or in-actions governments can take.

Our operations involve the use, transportation and disposal of toxic, hazardous and/or radioactive materials and could result in liability without regard to fault or negligence.

Our operations involve the use, transportation, and disposal of toxic, hazardous and radioactive materials. A release of these materials could pose a health risk to humans or animals. If an accident were to occur, its severity would depend on the volume of the release and the speed of corrective action taken by emergency response personnel, as well as other factors beyond our control, such as weather and wind conditions. Actions taken in response to an actual or suspected release of these materials, including a precautionary evacuation, could result in significant costs for which we could be legally responsible. In addition to health risks, a release of these materials may cause damage to, or the loss of, property and may adversely affect property values. Additionally, we may be responsible for decontamination or decommissioning of facilities where we conduct, or previously conducted, operations. Activities of our contractors, suppliers or other counterparties similarly may involve toxic, hazardous, and radioactive materials and we may be liable contractually, or under applicable law, to contribute to remedy damages or other costs arising from such activities, including the decontamination or decommission of third-party facilities.

We lease facilities from DOE near Piketon, Ohio. Pursuant to the Price-Anderson Act, as well as the HALEU Contract, DOE has agreed to indemnify the Company’s subsidiaries who are party to those agreements, and other Company entities who fall under the definition of a person indemnified under the Atomic Energy Act of 1954, against claims for public liability (as defined in the Atomic Energy Act) arising out of or in connection with activities under those leases and the HALEU Contract, as applicable, resulting from a nuclear incident or precautionary evacuation including transportation. If an incident or evacuation is not covered under DOE indemnification, we could be financially liable for damages arising from such incident or evacuation, which could have an adverse effect on our results of operations and financial condition.

While DOE has provided indemnification pursuant to the Price-Anderson Act, there could be delays in obtaining reimbursement for costs from DOE and DOE may also determine that some or all costs are not reimbursable under the indemnification. In addition, the Price-Anderson Act indemnification does not cover loss or damage due to a nuclear incident to property located on the leased facilities.

Centrus and Enrichment Corp. have been named as defendants in class action lawsuits alleging damages resulting from releases at the facilities we leased in the past at the Portsmouth Gaseous Diffusion Plant, and the centrifuge facilities we still lease near Piketon, Ohio. These claims include allegations of damages that the plaintiffs assert are not covered by the Price-Anderson Act, which claims we and the other defendants have challenged. If DOE were to determine that the Price-Anderson Act did not apply, we would have to pay all or part of any damages awarded as a result of such claims, the cost to us, including legal fees, could adversely affect our results of operations and financial condition. Refer to Note 16, Commitments and Contingencies — Legal Matters, of our consolidated financial statements in Part IV of this Annual Report for further details.

In our contracts, we seek to protect ourselves from liability, but there is no assurance that such contractual limitations on liability will be effective in all cases. The costs of defending against a claim arising out of a nuclear

28

incident or precautionary evacuation, and any damages awarded as a result of such a claim, could adversely affect our results of operations and financial condition.

Our certificate of incorporation gives us certain rights with respect to equity securities held (beneficially or of record) by foreign persons. If levels of foreign ownership set forth in our certificate of incorporation are exceeded, we have the right, among other things, to redeem or exchange common stock held by foreign persons, and in certain cases, the applicable redemption price or exchange value may be equal to the lower of fair market value or a foreign person’s purchase price.

Our certificate of incorporation gives us certain rights with respect to shares of our common stock held (beneficially or of record) by foreign persons. Foreign persons are defined in our certificate of incorporation to include, among others, an individual who is not a U.S. citizen, an entity that is organized under the laws of a non-U.S. jurisdiction and an entity that is controlled by individuals who are not U.S. citizens, or by entities that are organized under the laws of non-U.S. jurisdictions.

The occurrence of any one or more of the following events is a “foreign ownership review event” and triggers the board of directors’ right to take various actions under our certificate of incorporation: (1) the beneficial ownership by a foreign person of (a) 5% or more of the issued and outstanding shares of any class of our equity securities, (b) 5% or more in voting power of the issued and outstanding shares of all classes of our equity securities, or (c) less than 5% of the issued and outstanding shares of any class of our equity securities or less than 5% of the voting power of the issued and outstanding shares of all classes of our equity securities, if such foreign person is entitled to control the appointment and tenure of any of our management positions or any director; (2) the beneficial ownership of any shares of any class of our equity securities by or for the account of a foreign uranium enrichment provider or a foreign competitor (defined in our certificate of incorporation as a “Contravening Person”); or (3) any ownership of, or exercise of rights with respect to, shares of any class of our equity securities or other exercise or attempt to exercise control of us that is inconsistent with, or in violation of, any regulatory restrictions, or that could jeopardize the continued operations of our facilities (defined in our certificate of incorporation as an “Adverse Regulatory Occurrence”). These rights include requesting information from holders (or proposed holders) of our securities, refusing to permit the transfer of securities by such holders, suspending or limiting voting rights of such holders, redeeming or exchanging shares of our stock owned by such holders on terms set forth in our certificate of incorporation, and taking other actions that we deem necessary or appropriate to ensure compliance with the foreign ownership restrictions.

The terms and conditions of our rights with respect to our redemption or exchange right in respect of shares held by foreign persons or Contravening Persons are as follows:

•Redemption price or exchange value: Generally, the redemption price or exchange value for any shares of our common stock redeemed or exchanged would be their fair market value. However, if we redeem or exchange shares held by foreign persons or Contravening Persons and our Board in good faith determines that such person knew or should have known that its ownership would constitute a foreign ownership review event (other than shares for which our Board determined at the time of the person’s purchase that the ownership of, or exercise of rights with respect to, such shares did not at such time constitute an Adverse Regulatory Occurrence), the redemption price or exchange value is required to be the lesser of fair market value and the person’s purchase price for the shares redeemed or exchanged.

•Form of payment: Cash, securities or a combination, valued by our board of directors in good faith.

•Notice: At least 30 days written notice of redemption is required; however, if we have deposited the cash or securities for the redemption or exchange in trust for the benefit of the relevant holders, we may redeem shares held by such holders on the same day that we provide notice.

Accordingly, there are situations in which a foreign stockholder or Contravening Person could lose the right to vote its shares or in which we may redeem or exchange shares held by a foreign person or Contravening Person and

29

in which such redemption or exchange could be at the lesser of fair market value and the person’s purchase price for the shares redeemed or exchanged, which could result in a significant loss for that person.

General Risk Factors

Failures to protect classified or other sensitive information, or security breaches of information technology (“IT”) systems could result in significant liability or otherwise have an adverse effect on our business.

Our business requires us to use and protect classified, sensitive, and other protected information as well as business proprietary information and intellectual property (collectively, “sensitive information”). Our computer networks and other information technology (“IT”) systems are designed to protect this information through the use of classified networks and other procedures. We routinely experience various cybersecurity threats, threats to our information technology infrastructure, unauthorized attempts to gain access to the Company’s sensitive information, and denial-of-service attacks, as do our customers, suppliers, subcontractors, and other business partners. The threats we face vary from attacks common to most industries, attacks by more advanced and persistent, highly organized adversaries, including nation states, which target us and other government contractors because we protect national security information. If we are unable to protect sensitive information, our customers or governmental authorities could question the adequacy of our threat mitigation and detection processes and procedures, and depending on the severity of the incident, the Company’s data, customers’ data, our employees’ data, our intellectual property, and other third-party data could be compromised. As a consequence of the persistence, sophistication, and volume of these attacks, we may not be successful in defending against all such attacks. Due to the evolving nature of these security threats and the national security aspects of much of the data we protect, the impact of any future incident cannot be predicted.

We have a number of suppliers and indirect suppliers with a wide variety of systems and cybersecurity capabilities and we may not be successful in preventing adversaries from exploiting possible weak links in our supply chain. We also must rely on this supply chain for detecting and reporting cyber incidents, which could affect our ability to report or respond to cybersecurity incidents in a timely manner. The costs related to cyber or other security threats or disruptions may not be fully insured or indemnified by other means.

A material network breach in the security of the IT systems of the Company or third parties for any reasons, including, but not limited to, human error, could include the theft of sensitive information, including, without limitation, our and our customers’ business proprietary and intellectual property. To the extent any security breach or human error results in a loss or damage to sensitive information, or in inappropriate or unauthorized disclosure of sensitive information, the breach could cause grave damage to the country’s national security and to our business. Threats, via insider threat or third parties, to our IT systems, are constantly evolving and there is no assurance that our efforts to maintain and improve our IT systems will be sufficient to meet current or future threats. Any event leading to a security breach or loss of, or damage to, data, whether by our employees or third parties, could result in negative publicity, significant remediation costs, legal liability, and damage to our reputation and could have a material adverse effect on our business, financial condition, results of operations, and cash flows. In an extreme case, DOE could terminate our permit to access classified information resulting in the elimination of our ability to continue American Centrifuge work or performance of DOE contracts, including the HALEU Contract.

The inability to attract and retain key personnel could have an adverse impact on our business.

The Company’s LEU and technical services segments require people with unique skills and experience in the uranium enrichment industry. It also requires people with U.S. security clearances. To train employees and obtain the required U.S. Security clearances for them can take considerable time and expense. The success of our business depends on key executives, managers, scientists, engineers and other skilled personnel. The ability to attract and retain these key personnel may be difficult in light of the uncertainties currently facing the business and changes we may make to the organizational structure to adjust to changing circumstances.

30

Changes in senior management could create uncertainty among our employees, customers, suppliers, and other third parties with which we do business. The inability to retain appropriately qualified and experienced senior executives could negatively affect our operations, strategic planning, and performance.

The potential for DOE to seek to terminate or exercise its remedies under the 2002 DOE-USEC Agreement and our other agreements with DOE, or to require modifications to such agreements that are adverse to our interests, may have adverse consequences on the Company.

The Company and DOE signed an agreement dated June 17, 2002, as amended (the “2002 DOE-USEC Agreement”), that requires the Company to develop, demonstrate, and deploy advanced enrichment technology in accordance with milestones and provides for remedies in the event of a failure to meet a milestone under certain circumstances. DOE has specific remedies under the 2002 DOE-USEC Agreement if we fail to meet a milestone or if we abandon or constructively abandon the commercial deployment of an advanced enrichment technology. These remedies include terminating the 2002 DOE-USEC Agreement, revoking our access to DOE’s centrifuge technology that is required for the success of the American Centrifuge project, the HALEU Contract or other projects, requiring us to transfer certain rights in the American Centrifuge technology and facilities to DOE, and to reimburse DOE for certain costs associated with the American Centrifuge project.

We have granted to DOE an irrevocable, non-exclusive right to use or permit third parties on behalf of DOE to use all centrifuge technology intellectual property (“Centrifuge IP”) royalty free for U.S. government purposes (which includes national defense purposes, including providing nuclear material to operate commercial nuclear power reactors for tritium production). We also granted an irrevocable, non-exclusive license to DOE to use such Centrifuge IP developed at our expense for commercial purposes (including a right to sublicense), which may be exercised only if we miss any of the milestones under the 2002 DOE-USEC Agreement or if we (or our affiliate or entity acting through us) are no longer willing or able to proceed with, or have determined to abandon, or have constructively abandoned, the commercial deployment of the centrifuge technology. Such a commercial purposes license is subject to payment of an agreed upon royalty to us, which will not exceed $665 million in the aggregate. While our long-term objective is to commercially deploy the American Centrifuge technology when it is commercially feasible to do so, DOE may take the position that we are no longer willing or able to proceed with commercial deployment, or have actually, or constructively, abandoned commercial deployment, and could invoke its rights under the license described above. Any of these actions could adversely impact our business and prospects.

DOE may seek to exercise remedies under these agreements and there is no assurance that the parties will be able to reach agreement on appropriate modifications to the agreements in the future. Moreover, even if the parties reach agreement on modifications to such agreements, there is no assurance that such modifications will not impose material additional requirements, provide DOE with material additional rights or remedies, or otherwise affect the overall economics of the American Centrifuge technology and our ability to finance and successfully deploy the technology. Any of these actions could have an adverse impact on our business and prospects.

Our U.S. government contract work is regularly reviewed and audited by the U.S. government and these reviews can lead to withholding or delay of payments to us, non-receipt of award fees, legal actions, fines, penalties and liabilities, and other remedies against us.

Our U.S. government contracts are subject to specific regulations such as the Federal Acquisition Regulation, among others, and also subject to audits, cost reviews, and investigations by the U.S. government contracting oversight agencies. Should a contracting agency determine that we have not complied with the terms of our contracts and applicable statutes and regulations, payments to us may be disallowed, which could result in adjustments to previously reported revenues and refunding of previously collected cash proceeds. Additionally, we may be subject to litigation brought by private individuals on behalf of the U.S. government under the Federal False Claims Act, which could include claims for treble damages. If we experience performance issues under any of our U.S. government contracts, the U.S. government retains the right to pursue remedies, which could include termination under any affected contract. Termination of a contract could adversely affect our ability to secure future

31

contracts, and could have material adverse effect on our business, financial condition, results of operations, and cash flows.

Our U.S. government contracts and subcontracts are dependent on continued U.S. government funding and government appropriations, which may not be made on a timely basis or at all, and could have an adverse effect on our business.

Current and future U.S. government contracts and subcontracts, including our HALEU Contract, are dependent on government funding, which are generally subject to Congressional appropriations. Our ability to perform under these federal contracts and subcontracts is dependent upon sufficient funding for, and timely payment by, the entities with which we have contracted. If the contracting governmental agency, or the prime contractor, does not receive sufficient appropriations, it may terminate our contract or subcontract (in whole or in part) or reduce scope of our contract or subcontract, or delay or reduce payment to us. Any inability to award us a contract or subcontract, any delay in payment, or the termination of a contract or subcontract, in whole or in part, due to a lapse in funding or otherwise, could adversely affect our business, financial condition or results of operations, or cash flows.

Changes to, or termination of, any agreements with the U.S. government, or deterioration in our relationship with the U.S. government, could adversely affect results of operations.

We are a party to a number of agreements and arrangements with the U.S. government that are important to our business including our HALEU Contract, the lease for the centrifuge facility near Piketon, Ohio, and the 2002 DOE-USEC agreement. Termination, expiration, or modification of one or more of these or other agreements could adversely affect our business and prospects. In addition, deterioration in our relationship with the U.S. agencies that are parties to these agreements could impair or impede our ability to successfully implement these agreements, which could adversely affect our business, financial condition or results of operations, or cash flows.

Our success depends on our ability to adapt to a rapidly changing competitive environment in the nuclear industry.

The uranium enrichment sector of the nuclear fuel cycle industry remains oversupplied, creating downward pressures on commodity pricing, with uncertainty regarding nuclear power generation. Changes in the competitive landscape may adversely affect pricing trends, change customer spending patterns, or create uncertainty. To address these changes, we may seek to adjust our cost structure and operations, and evaluate opportunities to grow our business organically or through acquisitions and other strategic transactions. We are actively considering, and expect to consider from time to time in the future, potential strategic transactions, which could involve, without limitation, changes in our capital structure, acquisitions and/or dispositions of businesses or assets, joint ventures or investments in businesses, products, or technologies. In connection with any such transaction, we may seek additional debt or equity financing, contribute or dispose of assets, assume additional indebtedness, or partner with other parties to consummate a transaction. Any such transaction may not result in the intended benefits and could involve significant commitments of our financial and other resources. Legal and consulting costs incurred in connection with debt or equity financing transactions in development are deferred and subject to immediate expensing if such a transaction becomes less likely to occur. If the actions we take in response to industry changes are not successful, our business, results of operations and financial condition may be adversely affected.

Item 1B. Unresolved Staff Comments

On December 20, 2021, we received a comment letter from the Staff of the SEC’s Division of Corporation Finance relating to our Annual Report on Form 10-K for the fiscal year ended December 31, 2020 and our Quarterly Report on Form 10-Q for the quarter ended September 30, 2021.

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

The Company’s certificate of incorporation authorizes 100,000,000 shares of common stock, consisting of 70,000,000 shares of Class A Common Stock, $0.10 par value per share (the “Class A Common Stock”) and 30,000,000 shares of Class B Common Stock, $0.10 par value per share (the “Class B Common Stock”), As of March 1, 2022, the Company has issued 14,393,133 shares of Common Stock, consisting of 13,673,933 shares of Class A Common Stock and 719,200 shares of Class B Common Stock. The Class B Common Stock was issued to Toshiba America Nuclear Energy Corporation (“Toshiba”) and Babcock & Wilcox Investment Company (“B&W”) and has the same rights, powers, preferences and restrictions and ranks equally in all matters with the Class A Common Stock, except voting. Holders of Class B Common Stock are entitled to elect, in the aggregate, two members of the Board of Directors of the Company, subject to certain holding requirements. Additionally, the Company has reserved 1,900,000 shares of Class A Common Stock under its management incentive plan, of which 844,293 shares were available for future awards as of December 31, 2021, including 120,000 shares associated with awards which terminated or were cancelled without being exercised.

The Class A Common Stock trades on the NYSE American LLC (the “NYSE American”) under the symbol “LEU”.

As of March 1, 2022, there were 13,673,933 shares of Class A Common Stock outstanding. As of March 1, 2022, there were approximately 850 holders of record and approximately 14,360 beneficial owners of the Company’s Class A Common Stock. As of March 1, 2022, there were two holders of record of the Company’s Class B Common Stock.

No cash dividends were paid in 2021 or 2020, and we have no intention to pay cash dividends in the foreseeable future. The indenture governing our 8.25% Notes, subject to certain exceptions, places certain restrictions on the ability of Enrichment Corp. to transfer cash and other assets to us. This could act as a constraint on our ability to pay dividends on our Class A Common Stock.

There were no unregistered sales of equity securities by the Company during the years ended December 31, 2021 or 2020.

Overview

Centrus Energy Corp., a Delaware corporation (“Centrus” or the “Company”), is a trusted supplier of nuclear fuel and services for the nuclear power industry, which provides a reliable source of carbon free energy. References to “Centrus”, the “Company”, “our”, or “we” include Centrus Energy Corp. and its wholly-owned subsidiaries as well as the predecessor to Centrus, unless the context indicates otherwise.

Centrus operates two business segments: (a) low-enriched uranium (“LEU”), which supplies various components of nuclear fuel to commercial customers from our global network of suppliers, and (b) technical solutions, which provides advanced engineering, design, and manufacturing services to government and private sector customers and is deploying uranium enrichment and other capabilities necessary for production of advanced nuclear fuel to power existing and next-generation reactors around the world.

Our LEU segment provides most of the Company’s revenue and involves the sale of nuclear fuel to customers that are primarily utilities that operate commercial nuclear power plants. The majority of these sales are for the enrichment component of LEU, which is measured in separative work units (“SWU”). Centrus also sells natural uranium (the raw material needed to produce LEU) and occasionally sells LEU with the natural uranium, uranium conversion, and SWU components combined into one sale.

LEU is a critical component in the production of nuclear fuel for reactors that produce electricity. We supply LEU and its components to both domestic and international utilities for use in nuclear reactors worldwide. We provide LEU from multiple sources, including our inventory, medium and long-term supply contracts, and spot purchases. As a long-term supplier of LEU to our customers, our objective is to provide value through the reliability and diversity of our supply sources.

Our global order book includes long-term sales contracts with major utilities through 2029. We have secured cost-competitive supplies of SWU under long-term contracts through the end of this decade to allow us to fill our existing customer orders and make new sales. A market-related price reset provision in our largest supply contract took effect at the beginning of 2019 – when market prices for SWU were near historic lows – which has significantly lowered our cost of sales and contributed to improved margins. Spot price indicators for SWU have risen by approximately 65% to $56 as of December 31, 2021, since bottoming out in August 2018.

In October 2020, the U.S. Department of Commerce reached agreement with the Russian Federation on an extension of the 1992 Russian Suspension Agreement (“RSA”), a trade agreement which allows for Russian-origin nuclear fuel to be exported to the United States in limited quantities. The two parties agreed to extend the agreement through 2040 and to set aside a significant portion of the quota for Centrus’ shipments to the United States through 2028 to execute our long-term supply (purchase) agreement (the “TENEX Supply Contract”) with the Russian government entity, TENEX, Joint-Stock Company (“TENEX”). This outcome allows for sufficient quota for Centrus to continue serving its utility customers.

Our technical solutions segment is deploying uranium enrichment and other capabilities necessary for production of advanced nuclear fuel to meet the evolving needs of the global nuclear industry and the U.S. government, while also leveraging our unique technical expertise, operational experience and specialized facilities to expand and diversify our business beyond uranium enrichment, offering new services to existing and new customers in complementary markets.

Our technical solutions segment is dedicated to the restoration of America’s domestic uranium enrichment capability to play a critical role in meeting U.S. national security and energy security requirements, advancing America’s nonproliferation objectives, repairing broken and vulnerable supply chains, providing good clean energy jobs and supporting the communities in which we operate, and in delivering the next-generation nuclear fuels that will power the future of nuclear energy as it provides reliable carbon-free power around the world.

37

The United States has not had a domestic uranium enrichment capability suitable to meet U.S. national security requirements since the Paducah Gaseous Diffusion Plant (“Paducah GDP”) shut down in 2013. Longstanding U.S. policy and binding nonproliferation agreements prohibit the use of foreign-origin enrichment technology for U.S. national security missions. Our AC100M centrifuge is currently the only deployment-ready U.S. uranium enrichment technology in the U.S. that can meet these national security requirements.

Centrus is working to pioneer U.S. production of High-Assay, Low-Enriched Uranium (“HALEU”), enabling the deployment of a new generation of HALEU-fueled reactors to meet the world’s growing need for carbon-free power. HALEU is a high-performance nuclear fuel component which is expected to be required by a number of advanced reactor and fuel designs that are now under development for commercial and government uses. While existing reactors typically operate on LEU with the uranium-235 isotope concentration below 5%, HALEU is further enriched so that the uranium-235 concentration is between 5% and 20%. The higher U-235 concentration offers a number of potential advantages, which may include better fuel utilization, improved performance, fewer refueling outages, simpler reactor designs, reduced waste volumes, and greater nonproliferation resistance.

The lack of a domestic HALEU supply is widely viewed as a major obstacle to the successful commercialization of these new reactors. For example, in surveys conducted by the U.S. Nuclear Industry Council in 2021 and 2020, advanced reactor developers indicated that the number one issue that “keeps you up at night” was access to HALEU. As the only company with a license from the Nuclear Regulatory Commission (“NRC”) to enrich up to 20% uranium-235 assay HALEU, Centrus is uniquely positioned to fill a critical gap in the supply chain and facilitate the deployment of these promising next-generation reactors.

The DOE has experienced a COVID-19 related supply chain delay in obtaining the HALEU storage cylinders. Since it is not possible to begin HALEU production without the storage cylinders, it would not be possible to complete the operational portion of the demonstration before the June 1, 2022 expiration date of the existing HALEU Contract. As a result, the DOE elected to change the scope of the HALEU Contract and move the operational portion of the demonstration to a new, competitively-awarded contract that would provide for operations beyond the term of the existing contract. On February 7, 2022, DOE issued a pre-solicitation notice for a request for proposal to complete the HALEU demonstration facility and to produce HALEU, noting that the “the Administration supports longer-term demonstration of production capability.” The pre-solicitation notice outlines a two-phase approach. Phase 1 consists of completing installation of the centrifuges – which DOE expects will take up to one year from contract signing – followed by one full year of cascade operations. The second phase consists of three optional, 3-year extensions to produce HALEU, so that the prospective contract could help support a total of one to ten years of cascade operations in addition to completing construction and centrifuge installation.

Centrus believes it is well-positioned to compete for a follow-on contract with DOE to operate the machines in Piketon but there is no assurance that the DOE will award such a contract to the Company. Congress has not yet adopted a Fiscal Year 2022 appropriations bill for the DOE, and there is no assurance that the proposed program, which would go beyond the scope and expiration of our existing contract, will be approved and funded.

The U.S. government has been operating under a series of continuing resolutions in Fiscal Year 2022. The DOE continues to support the HALEU program during the continuing resolution period, and has incrementally increased the government’s cost share ceiling as funds have become available. Currently, DOE has provided additional funding, and increased the government’s cost share ceiling to $126.7 million.

Additional COVID-19 related impacts, delays in DOE furnishing equipment, or changes to the existing scope of the HALEU Contract could result in further material increases to our estimate of the costs required to complete the existing HALEU Contract, as well as delay completion of the contract. The Company does not currently have a contractual obligation to perform work in excess of the funding provided by DOE and, therefore, no additional loss has been accrued as of December 31, 2021. If DOE does not commit to fully fund

38

the additional costs, and the Company nevertheless commits to a plan to complete the demonstration cascade and produce HALEU, we may incur material additional costs or losses in future periods that could have an adverse impact on our financial condition and liquidity.

We believe our investment in the HALEU technology will position the Company to meet the needs of government and commercial customers in the future as they deploy advanced reactors and next generation fuels. At present, there are a number of advanced reactors under development. For example, of the ten advanced reactor designs selected by the U.S. Department of Energy for its Advanced Reactor Demonstration Program, nine will require HALEU.In addition, the first non-light water reactor to have begun active NRC-license review requires HALEU.The U.S. Department of Defense also plans to construct a prototype HALEU-fueled mobile microreactor in the next three to four years as part of a program called “Project Pele.”The U.S. Air Force also announced plans to deploy a microreactor at Eielson Air Force Base in Alaska.While the use of HALEU is not an express requirement of the Air Force program, the vast majority of microreactor designs are expected to need HALEU.

Advanced nuclear reactors promise to provide an important source of reliable carbon-free power. By investing in HALEU technology now, and as the only American-based company currently pursuing HALEU enrichment capability, we believe the Company is well positioned to capitalize on a potential new market as the demand for HALEU-based fuels increases in the mid to late-2020s with the development of advanced reactors. However, there are no guarantees about whether or when government or commercial demand for HALEU will materialize, and there are a number of technical, regulatory, and economic hurdles that must be overcome for these fuels and reactors to come to the market. Also, foreign government-owned and government-operated competitors could seek to enter the market and offer HALEU at more competitive prices. There is one known foreign government-owned source which currently has the capability to produce HALEU although this source is currently subject to trade restrictions that limit the amount of material from this source which may be imported into the United States. Other foreign government-owned entities which are not currently subject to U.S. trade restrictions, however, may enter the market. One such foreign-government owned entity has expressed an interest in and potential capability for HALEU production but has not committed publicly to enter the market to enrich above 10% uranium-235 enrichment assays. This entity has indicated publicly that it would take six to seven years to be able to produce HALEU.

The Company continues to review opportunities to improve its capital structure and to enhance shareholder value. As a result, pursuant to a sales agreement with its agents, the Company sold at the market price an aggregate of 1,516,467 shares of its Class A Common Stock in 2021, for a total of $44.2 million. After expenses and commissions paid to the agents the Company’s proceeds total $42.4 million. Additionally, the Company recorded direct costs of $0.3 million related to the issuance. The shares of Class A Common Stock were issued pursuant to the Company’s shelf registration statement on Form S-3 (File No. 333-239242), which became effective on August 5, 2020, and a prospectus supplement dated December 31, 2020 to the prospectus, dated August 5, 2020. At present, the Company has $5.8 million remaining available for sale under the prospectus supplement dated December 31, 2020, and may from time to time sell additional shares through the sales agreement at the then market price. The Company currently intends to use the net proceeds from this offering for general working capital purposes, to invest in technology development, or to repay outstanding debt.

In addition and in connection with the entry into an amendment (the “Voting Agreement Amendment”) to its existing Voting and Nomination Agreement with Mr. Morris Bawabeh, Kulayba LLC and M&D Bawabeh Foundation, Inc., the Company and Kulayba LLC also entered into an Exchange Agreement, dated February 2, 2021 (the “Exchange Agreement”), pursuant to which Kulayba LLC agreed to exchange (the “Exchange”) 3,873 shares of the Company’s outstanding Series B Senior Preferred Stock, par value $1.00 per share, representing a $5,000,198 liquidation preference (including accrued and unpaid dividends), for (i) 231,276 shares of the Company’s Class A Common Stock, priced at the closing market price of $21.62 on the date the Exchange Agreement was signed and (ii) a Centrus Energy Corp. Warrant to Purchase Common Stock (the “Warrant”), exercisable for 250,000 shares of Common Stock at an exercise price of $21.62 per share, which

39

was the closing market price on the date the Exchange Agreement was signed, subject to certain customary adjustments pursuant to the terms of the Warrant. The Company retired the 3,873 shares of Series B Senior Preferred Stock received by the Company under the Exchange Agreement.

On November 23, 2021, pursuant to a tender offer announced on October 20, 2021, the Company completed the purchase of 36,867 shares of its outstanding Series B Senior Preferred Stock at a price per share of $1,145.20, less any applicable withholding taxes, for an aggregate purchase price of approximately $42.2 million. On November 23, 2021, the Company issued a Notice of Full Redemption providing for the redemption of any and all shares of the Company’s Series B Senior Preferred Stock outstanding after consummation of the Company’s tender offer to purchase all of its issued and outstanding Series B Senior Preferred Stock. On December 15, 2021, the Company completed the redemption of all 980 outstanding Series B Senior Preferred Stock for aggregate cash consideration of $1.1 million. The aggregate purchase price of $43.3 million was offset by direct costs totaling $0.9 million. For additional details, refer to Note 15,Stockholders’ Equity, of the consolidated financial statements in Part IV of this Annual Report.

In the years following the 2011 Fukushima accident in Japan, the published market prices for uranium enrichment declined more than 75% through mid-2018. While the monthly price indicators have since increased, the uranium enrichment segment of the nuclear fuel market remains oversupplied and faces uncertainty about future demand for nuclear power generation. Changes in the competitive landscape affect pricing trends, change customer spending patterns, and create uncertainty. To address these changes, we have taken steps to adjust our cost structure; we may seek further adjustments to our cost structure and operations and evaluate opportunities to grow our business organically or through acquisitions and other strategic transactions.

We are also actively considering, and expect to consider from time to time in the future, potential strategic transactions, which could involve, without limitation, acquisitions and/or dispositions of businesses or assets, joint ventures or investments in businesses, products or technologies, or changes to our capital structure. In connection with any such transaction, we may seek additional debt or equity financing, contribute or dispose of assets, assume additional indebtedness, or partner with other parties to consummate a transaction.

Refer to Part I, Item 1, Business, for additional information.

COVID-19 Update

The Company has taken actions to protect its workforce and to maintain critical operations during the COVID-19 pandemic. Travel, operational, and other restrictions imposed by the U.S. and foreign governments may impact our ability to make future sales and may impact the ability of our suppliers, including our suppliers of low enriched uranium, to perform under their contracts. As of the date of this filing, our LEU segment operations have not been materially affected by the COVID-19 pandemic and we are working with our suppliers, fabricators, and customers to monitor the situation closely, including with respect to the impact of emerging variants. However, our technical solutions segment has been impacted by supply chain disruptions and increased costs as a result of the COVID-19 pandemic.
