Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with, and is qualified in its entirety by reference to, the Consolidated Financial Statements and related notes appearing elsewhere in this report.

This discussion contains forward-looking statements that involve risks and uncertainties. Actual results could differ significantly from the results discussed in the forward-looking statements particularly in light of the economic, social and market uncertainty created by, among other things, the war in Ukraine. See “Forward-Looking Statements” at the beginning of this Annual Report on Form 10-K.

Overview

Centrus, a Delaware corporation (the “Company”, “we” or “us”), is a trusted supplier of nuclear fuel components 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.

Published spot price indicators for SWU reached historic highs in April 2009 at $163 per SWU. In the years following the 2011 Fukushima accident in Japan, spot prices declined more than 75%, bottoming out in August 2018 at $34 per SWU. This was followed by a slow and steady rise, reaching $56 per SWU by December 31, 2021. In 2022, spot prices increased substantially, reaching $110 per SWU by December 31, 2022. In 2023, spot prices continued to increase, reaching $155 per SWU by December 31, 2023. This represents an increase of 41% since the beginning of the year and 356% over the 2018 historic low. This sudden surge in the SWU spot price has been driven by uncertainty created as a result of Russia’s invasion of Ukraine, coupled with growing interest in nuclear power as a source of secure and carbon-free energy.

When Russian supply is included, the uranium enrichment segment of the global nuclear fuel market is oversupplied, but without Russian supply, the global market would be undersupplied for uranium enrichment. Further, it is not clear that there are sufficient inventories of enriched uranium in the United States to compensate for a loss of Russian supply, absent new capacity that will take a number of years to deploy. A report issued by the International Atomic Energy Agency in 2023, for example, reported that while U.S. utilities may have enough inventory to cover one reload of their reactors, “truly strategic physical stockpiles are almost non-existent.”2

Changes in the supply-demand balance and in the competitive landscape arising from the war in Ukraine may affect pricing trends, change customer spending patterns, and create uncertainty in the uranium market. At the same time, there remains uncertainty about future demand for nuclear power generation. To address these changes, we will continue to evaluate opportunities to grow our business organically or through acquisitions and other strategic transactions.

Under the HALEU Demonstration Contract, Centrus was engaged by the DOE to construct a cascade of 16 AC100M centrifuges in Piketon to demonstrate HALEU production. The Company’s goal under the HALEU Demonstration Contract was to complete the demonstration and scale up production of HALEU and LEU, to meet the needs of new and existing reactors as well as national security and other U.S. government requirements for enriched uranium. The HALEU Demonstration Contract was originally set to expire on June 1, 2022; however, it was extended through November 30, 2022. The Company is currently performing closeout activities on the HALEU Demonstration Contract. The DOE elected to change the scope of the HALEU Demonstration Contract and moved the operational portion of the demonstration to a new, competitively-awarded contract that would provide for operations beyond the term of the existing HALEU Demonstration Contract. The DOE hasincrementally increased funds on the HALEU Demonstration Contract with total funding to date of $173.0 million.

On November 10, 2022, after a competitive solicitation, the DOE notified Centrus that the Company had won the HALEU Operation Contract and work began December 1, 2022. The base contract value is approximately $150 million in two phases through 2024. Phase 1 included an approximately $30 million cost share contribution from Centrus matched by approximately $30 million from the DOE to complete construction of the cascade, begin operations and produce the initial 20 kilograms of HALEU UF6 by no later than December 31, 2023.

Phase 2 of the contract includes continued operations and maintenance, and production for a full year at an annual production rate of 900 kilograms of HALEU UF6. The DOE will own the HALEU produced from the demonstration cascade and Centrus will be compensated on a cost-plus-incentive-fee basis, with an expected Phase 2 contract value of approximately $90 million, subject to Congressional appropriations. The HALEU Operation Contract also gives DOE three 3-year options to pay for up to nine additional years of production from the cascade beyond the base contract; those options are at the DOE’s sole discretion and subject to the availability of Congressional appropriations. Concurrently, pursuant to an amendment to our lease for the Piketon facility, the DOE assumed all D&D liabilities arising out of the HALEU Operation Contract.

Under the HALEU Operation Contract, DOE is contractually required to provide the 5B Cylinders necessary for us to collect the output of the cascade, but supply chain challenges have created difficulties for DOE in securing 5B Cylinders for the entire production year. To support the DOE in mitigating the risk of further delays in delivery of 5B Cylinders, the Company received technical direction and a contract modification from the DOE to procure compliant 5B Cylinders and components while the contractual obligation to furnish compliant 5B Cylinders under the HALEU Operation Contract continues to rest with the DOE. During periods where 5B Cylinders are insufficient, the Company will not be able to produce HALEU, but will be able to continue operations of the cascade and perform preventive maintenance and regulatory compliance type activities. Centrus anticipates that the delays in obtaining sufficient 5B Cylinders will be temporary, but no longer expects to achieve delivery of the 900 kilograms of HALEU UF6 anticipated for Phase 2 of the contract which extends through November 2024. The target fee for Phase 2 of the contract had been estimated to be $7.5 million based on the estimated costs for the contract and is subject to a contract minimum fee of $6.9 million. The Company is also performing additional work on infrastructure and facility repairs under DOE’s technical direction and subsequent contract modification. For further details refer to Item 1 - Business -Technical Solutions - Government Contracting.

On February 9, 2023, the Company announced that construction and initial testing of the demonstration cascade and most of the support systems were complete. On June 12, 2023, following the completion of its operational readiness reviews, the NRC issued a letter authorizing the Company to introduce uranium hexafluoride into the HALEU cascade of centrifuges. This was a critical milestone in advancing toward the production of HALEU and the final NRC approval required before starting enrichment operations. During the third quarter of 2023, the Company completed construction of the remaining support systems, including a fissile materials storage area, for HALEU storage. On September 6, 2023, the Company announced that it was conducting final system tests and other preparations so that production of HALEU could begin. On September 21, 2023, the NRC granted final approval for the company to produce the quantity of HALEU required by Phase 1 of the contract. On October 11, 2023, the Company announced that it began enrichment operations in Piketon, Ohio. On November 7, 2023, the Company announced that it made its first delivery of HALEU to the DOE, completing Phase 1 by successfully demonstrating its HALEU production process. During November 2023, the Company transitioned to Phase 2 of the HALEU Operation Contract.

52

The DOE is contemplating awarding additional contracts to ensure availability of HALEU for the ARDP and for the advanced reactor market in general, and received a $700 million congressional appropriation from the Inflation Reduction Act as a first step in establishing a domestic supply chain for HALEU. On June 5, 2023, the DOE issued two draft requests for proposals (“RFPs”) seeking public comment, the first focusing on production of HALEU and the second focusing on deconversion of HALEU into different forms used to fabricate fuels needed by various advanced reactor developers. Centrus submitted comments in response to the draft RFPs to ensure the RFPs promote deployment of HALEU capacity to meet U.S. commercial and government needs for HALEU produced with U.S. technology. On November 28, 2023, the DOE issued an RFP focusing on deconversion of HALEU and on January 9, 2024, issued an RFP focusing on the production of HALEU.The Company expects to bid on both RFPs, with the goal of expanding HALEU production capability at the Piketon facility, subject to, among other things, availability of funding and/or offtake commitments.

The war in Ukraine has contributed to a significant increase in market prices for enrichment and prompted calls for public and private investment in new, domestic uranium enrichment capacity not only for HALEU production but also for LEU production to support the existing fleet of reactors. As a result, Centrus is exploring the opportunity to deploy LEU enrichment alongside HALEU enrichment to meet a range of commercial and U.S. government requirements, which would bring cost synergies while increasing revenue opportunities. Our ability to deploy LEU and/or HALEU enrichment, and the timing, sequencing, and scale of those capabilities, is subject to the availability of funding and/or offtake commitments.

The Energy Act of 2020, which was signed into law in December 2020, requires the DOE to establish a program to support the availability of HALEU for civilian domestic research, development, demonstration, and commercial use. The Energy Act also reauthorized DOE nuclear energy research, development, demonstration, and commercial application activities, including advanced fuel, research and development for advanced reactors, used fuel technologies, and integration of nuclear energy systems for both existing plants and advanced nuclear concepts. It also authorized the funding of an ARDP which was launched by the DOE in May 2020. There are a number of advanced reactors under development that would use HALEU. Nine of the ten advanced reactor designs selected by the DOE for its ARDP will require HALEU. Various agencies of the U.S. government, including the U.S. Department of Defense, the Defense Advanced Research Projects Agency, and the DOE supporting the development of microreactors which demonstrates the focus on both the development of microreactors and the ultimate need for HALEU. We believe our investments in advanced enrichment technology and our progress in demonstrating HALEU production 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 and also offers potential cost synergies for a return to LEU production. Further, the Company is taking steps to pursue, including through the exploration of strategic partnerships, technologies that are complementary to HALEU production and critical to the HALEU ecosystem, including deconversion and fuel fabrication.

While the monthly price indicators have increased for several years, the uranium enrichment segment of the nuclear fuel market remains oversupplied and faces uncertainty about future demand for nuclear power generation. However, without Russian supply, the global market would be undersupplied for uranium enrichment. 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.

Market Conditions and Outlook

The global nuclear industry outlook has begun to improve after many years of decline and stagnation. The development of advanced small and large-scale reactors, innovative advanced fuel types, and the commitment of nations to begin deploying or to increase the share of nuclear power in their nations has created optimism in the market. Part of the momentum has resulted from efforts to lower greenhouse gas emissions to combat climate change and improve health and safety.

According to the WNA, as of January 2024, there were approximately 60 reactors under construction worldwide, about a third of which are in China. The United States, with over 90 operating reactors, remains the world’s largest market for nuclear fuel. The nuclear industry in the United States, Japan, and Europe faces headwinds as well as opportunities. In the United States, the industry has been under pressure from the expansion of subsidized renewable energy as well as relatively low-cost natural gas resources in recent years, although natural gas prices in the U.S. electricity sector tripled between 2020 and 2022 according to data from the EIA. Twelve U.S. reactors have prematurely shut down in the past ten years and others could shut down in the next few years. At the same time, one large reactor is under construction, and the DOE recently released a report outlining a pathway to deployment of approximately 200 gigawatts of additional capacity by 2050 which would triple the nuclear energy capacity in the United States.

The IEA projects that global nuclear energy generation will grow substantially in the next three decades. In the IEA’s 2023 World Energy Outlook, nuclear generation is forecasted to grow by 25 percent by 2030 and 45 percent by 2040 under the “Stated Policies” scenario. In the “Net Zero Emissions by 2050” scenario, nuclear generation would grow by 47 percent by 2030 and more than double by 2040.

54

As a consequence of the March 2011 earthquake and tsunami in Japan, over 60 reactors in Japan and Germany were taken offline, and other countries curtailed or slowed their construction of new reactors or accelerated the retirement of existing plants. Eleven reactors in Japan have restarted and additional reactors are expected to restart through 2024; more of Japan’s reactors are expected to restart in subsequent years. Due to the war in Ukraine, the EU is encouraging its member countries to reconsider the planned early retirement of existing plants in order to reduce reliance on Russian gas imports.

In October 2020, the DOC reached an agreement with the Russian Federation on an extension of the 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 annual quota for Centrus’ shipments to the United States through 2028 to execute our long-term TENEX Supply Contract with TENEX. This outcome allows for sufficient quota for Centrus to continue serving its utility customers and support its investments in building new capacity. Use of this quota is subject to compliance with limitations under the RSA. These limitations include a requirement that we return UF6 to TENEX for the LEU we receive under the TENEX Supply Contract at approximately the same time that we deliver the LEU to our customers. Our ability to meet this requirement depends on the capacity or willingness of the facilities where natural uranium is supplied to us by customers, to allow us to deliver this natural uranium to TENEX. We were recently notified by one facility that it will no longer receive natural uranium for TENEX. As a result, we will need to rely to a greater extent on deliveries at other processors or explore other options in order to comply with the RSA’s natural uranium delivery requirement.

On July 13, 2023, the Company and TerraPower, LLC (“TerraPower”) entered into a memorandum of understanding (“MOU”) to expand their collaboration aimed at establishing commercial-scale, domestic production capabilities for HALEU to fuel the Natrium TM reactor that TerraPower is building in Wyoming. Under this MOU, the Company and TerraPower will explore collaboration to ensure the Natrium demonstration reactor has access to HALEU at the milestones necessary to meet the project's 2030 operation date. Subject to a definitive agreement to be negotiated, Centrus would work toward scaling up production capacity with additional centrifuge cascades to meet TerraPower's fuel requirements.

On August 28, 2023, the Company and Oklo Inc. (“Oklo”) announced a new MOU to support the deployment of Oklo’s advanced fission powerhouses and advanced nuclear fuel production in Southern Ohio subject to a definitive agreement to be negotiated. Oklo and Centrus plan to enter into a broad range of collaboration programs supporting the development and operation of Oklo’s Aurora powerhouses, including supply of HALEU produced by Centrus at the Piketon, Ohio facility. Centrus also intends to buy clean, reliable, and affordable energy from Oklo’s planned Ohio plants to power its HALEU production facility.

The war in Ukraine has escalated tensions between Russia and the international community. As a result, the United States and other countries have imposed, and may continue imposing, additional sanctions and export controls against certain Russian products, services, organizations and/or individuals. While sanctions imposed to date do not preclude the import of Russian uranium products into the United States, it is possible that additional restrictions could be added in the future that would affect our ability to purchase and re-sell Russian uranium enrichment, or implement the TENEX Supply Contract, which could have a negative material impact on our business. Further, sanctions by the United States, Russia or other countries may impact our ability and cost to transport, export, import, take delivery, or make payments related to the LEU we purchase and may require us to increase purchases from non-Russian sources to the extent available. For example, due to restrictions imposed by Canada on the ability of Canadian persons and entities to provide ocean transportation services to Russia, a permit is required for our shipper, a Canadian company, to transport the LEU that we procure under the TENEX Supply Contract to the United States. A Canadian permit issued to our shipper was recently extended to early July 2024, but for so long as the sanctions remain in place, the shipper will require further extensions for us to continue to use the shipper for imports of this LEU beyond July 2024.

55

In response to the war in Ukraine, there have been proposals in U.S. Congress and elsewhere to ban imports of uranium products that could affect our ability to import LEU in one or more years under the TENEX Supply Contract. In December 2023, for example, the U.S. House of Representatives passed H.R. 1042, the “Prohibiting Russian Uranium Imports Act”, that, if enacted into law, would ban imports of LEU from Russia beginning ninety (90) days after the date of enactment.Any U.S. ban on imports of Russian LEU would represent a significant risk to our business. Through 2027, well over one-half of the LEU that we expect to deliver to customers will come from material supplied to us under the TENEX Supply Contract. While we have other sources, they are not sufficient to replace the TENEX supply. Accordingly, if the current proposals in Congress are adopted, we would apply for waivers from the Secretary of Energy to allow us to continue supplying our customers, which are uncertain to be granted at this time. Refer to Part 1, Item 1- Business and Item 1A - Risk Factors, Operational Risks and - War in Ukraine Risks, for further discussion.

In addition to limitations targeted specifically at imports of LEU, the expanding sanctions imposed by the United States and foreign governments on the mechanisms used to make payments to Russia and to obtain services including transportation and other services have increased the risk that implementation of the TENEX Supply Contract may be disrupted in the future.

Given all the foregoing, we continue to monitor the situation closely and assess the potential impact of any new sanctions and how the impact on the Company might be mitigated.

For further discussion of these risks and uncertainties, refer to Part I, Item 1A, Risk Factors - The current war in Ukraine and related international sanctions and restrictions on trade could have a material adverse impact on our business, results of operations, and financial condition.

Operating Results

Our revenues, operating results, and cash flows can fluctuate significantly from quarter to quarter and year to year.Our Order Book in the LEU segment consists primarily of long-term, fixed commitment contracts, and we have visibility on a significant portion of our revenue for 2024-2026.

Given the current uncertainty and disruption in the market, due to among other things, the war in Ukraine, we are no longer providing guidance on our results of operations for 2024.Please see Forward Looking Statements at the beginning of this Annual Report on Form 10-K.

Our Order Book in the LEU segment extends to 2030. As of December 31, 2023 and December 31, 2022, our Order Book was approximately $1.0 billion. The Order Book is the estimated aggregate dollar amount of revenue for future SWU and uranium deliveries, and includes approximately $0.3 billion of deferred revenue and advances from customers as of December 31, 2023, whereby customers have made advance payments to be applied against future deliveries. No orders in our Order Book are considered at risk related to customer operations. These medium and long-term contracts are subject to significant risks and uncertainties, including existing import laws and restrictions, such as the RSA, which limits imports of Russian uranium products into the United States and applies to our sales using material procured under the TENEX Supply Contract as well as the potential for additional sanctions and other restrictions in response to the evolving situation regarding the war in Ukraine.

Our future operating results are subject to uncertainties that could affect results either positively or negatively. Among the factors that could affect our results are the following:

•Armed conflicts, including the war in Ukraine, government actions and other events or third-party actions that disrupt supply chains, production, transportation, payments, and importation of nuclear materials or other critical supplies or services;

•The potential for sanctions and other measures affecting the importation, sales or purchases of SWU or uranium or goods or services required for the purchase or delivery of such SWU or uranium;

56

•The availability and terms of additional purchases or sales of SWU and uranium;

•Conditions in the LEU and energy markets, including pricing, demand, operations, government restrictions on imports, exports or investments, and regulations of our business and activities and those of our customers, suppliers, contractors, and subcontractors;

•Timing of customer orders, related deliveries, and purchases of LEU or LEU components;

•Costs of and future funding and demand for HALEU;

•Financial market conditions and other factors that may affect pension and benefit liabilities and the value of related assets;

•The outcome of legal proceedings and other contingencies;

•Potential use of cash for strategic or financial initiatives;

•Actions taken by customers and suppliers, including actions that might affect existing contracts;

•The government’s inability to satisfy its obligations, including supplying government furnished equipment under its agreements with the Company or processing security clearances due to a shutdown or other reasons; and

•Market, international trade, and other conditions impacting Centrus’ customers and the industry.

For further discussion of these risks and uncertainties, refer to Part I, Item 1A, Risk Factors.

Revenue

We have two reportable segments: the LEU segment and the Technical Solutions segment.

Revenue from our LEU segment is derived primarily from:

•sales of the SWU component of LEU;

•sales of natural uranium hexafluoride, uranium concentrates or uranium conversion; and

•sales of enriched uranium product that include both the natural uranium hexafluoride and SWU components of LEU.

Our Technical Solutions segment reflects our technical, manufacturing, engineering, and operations services offered to public and private sector customers, including engineering and testing activities as well as technical and resource support currently being performed by the Company. This includes the HALEU Operation Contract and other contracts with public and private sector customers.

SWU and Uranium Sales

Revenue from our LEU segment accounted for approximately 84% of our total revenue for the year ended December 31, 2023. The majority of our customers are domestic and international utilities that operate nuclear power plants, with international sales constituting approximately 40% of revenue from our LEU segment since 2021. Our agreements with electric utilities are primarily medium-term 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. Contracts where we sell both the SWU and natural uranium hexafluoride components of LEU to utilities or where we sell natural uranium hexafluoride to utilities and other nuclear fuel related companies are generally shorter-term, fixed-commitment contracts. Individual customer orders for the SWU component of LEU fulfilled in 2023 averaged approximately $7.1 million per order. As a result, a relatively small shift in the timing of customer orders for LEU may cause significant variability in our operating results year over year.

57

Utility customers, in general, have the option to make payment but defer receipt of SWU and uranium products purchased from Centrus beyond the contractual sale period, resulting in the deferral of costs and revenue recognition. Refer to Note 2, Revenue and Contracts with Customers, in the Consolidated Financial Statements in Part IV of this Annual Report for further details.

Our financial performance over time can be affected significantly by changes in prices for SWU and natural uranium hexafluoride. Market prices for SWU and uranium hexafluoride significantly declined from 2011 until mid-2018, when they began to trend upward. More recently, market uncertainty in the wake of the Russian invasion of Ukraine has driven SWU and uranium hexafluoride prices sharply higher. Since our Order Book includes contracts awarded to us in previous years, the average SWU price billed to customers typically lags published price indicators by several years. While some newer sales reflect the low prices prevalent in recent years, certain older contracts included in our Order Book have sales prices that are significantly above current market prices.

Recent proposals, including proposed U.S. legislation, to severely limit or cut off supply of LEU from Russia have drawn attention to the potential for significant tightening of supplies in the market.Russian enrichment plants represent 44% of the world’s capacity, and Russian capacity significantly exceeds its domestic needs. According to data from the WNA, the annual enrichment requirements of reactors worldwide outside of Russia vastly exceeds the available supply of non-Russian enrichment, which potentially threatens the viability of some reactors, including those in the United States.While inventories and increased production at non-Russian plants may mitigate the shortfall, these options would not fully replace Russian supply. Deployment of new capacity ultimately could replace Russian enrichment but this capacity will take a number of years and significant funding from private or government sources to come online.

The following chart summarizes long-term and spot SWU price indicators, and a spot price indicator for UF6, as published by TradeTech, LLC in Nuclear Market Review:

SWU and Uranium Market Price Indicators*

58

Our contracts with customers are denominated primarily in U.S. dollars, and, although revenue has not been materially affected by changes in the foreign exchange rate of the U.S. dollar, we may have a competitive price advantage or disadvantage obtaining new contracts in a competitive bidding process depending upon the weakness or strength of the U.S. dollar. Under a customer contract that commenced deliveries in 2023, payments are denominated in euros and the payments are subject to exchange rate risk. Costs of our primary competitors are denominated in other currencies. Our contracts with suppliers are primarily denominated in U.S. dollars. We have a SWU supply agreement that commenced in 2023, with prices payable in a combination of U.S. dollars and euros, but with a contract-defined exchange rate.

On occasion, we will accept payment for SWU in the form of natural uranium hexafluoride. Revenue from the sale of SWU under such contracts is recognized at the time LEU is delivered and is based on the fair value of the natural uranium hexafluoride at contract inception, or as the quantity of natural uranium hexafluoride is finalized, if variable.

Cost of sales for SWU and uranium is based on the amount of SWU and uranium hexafluoride sold and delivered during the period and unit inventory costs. Unit inventory costs are determined using the average cost method. Changes in purchase costs have an effect on inventory costs and cost of sales. Cost of sales includes costs for inventory management at off-site licensed locations. Cost of sales also includes certain legacy costs related to former employees of the Portsmouth GDP and Paducah GDP.

Critical Accounting Policies and Estimates

Our significant accounting policies are summarized in Note 1, Summary of Significant Accounting Policies, of our Consolidated Financial Statements in Part IV of this Annual Report, which were prepared in accordance with U.S. GAAP. U.S. GAAP and related accounting pronouncements, implementation guidelines and interpretations with regard to a wide range of matters that are relevant to our business are complex and involve many subjective assumptions, estimates and judgments that are, by their nature, subject to substantial risks and uncertainties. Critical accounting estimates are those that require management to make assumptions about matters that are uncertain at the time the estimate is made and for which different estimates, often based on complex judgments, probabilities and assumptions that we believe to be reasonable, but are inherently uncertain and unpredictable, could have a material impact on our operating results and financial condition. It is also possible that other professionals, applying their own judgment to the same facts and circumstances, could develop and support a range of alternative estimated amounts. We are also subject to risks and uncertainties that may cause actual results to differ from estimated amounts, such as the healthcare environment, legislation and regulation. Additionally, changes in accounting rules or their interpretation could significantly affect our results of operations and financial condition.

The sensitivity analyses used below are not intended to provide a reader with our predictions of the variability of the estimates used. Rather, the sensitivities used are included to allow the reader to understand a general cause and effect of changes in estimates.

We have identified the following to be our critical accounting estimates:

Revenue Recognition - Technical Solutions

Revenue for the Technical Solutions segment is recognized over the contractual period as services are rendered. The Company recognizes revenue over time as it performs on these contracts because of the continuous transfer of control to the customer.

59

The Company determines the transaction price for each contract based on the consideration it expects to receive for the products or services being provided under the contract. If transaction prices are not stated in the contract for each performance obligation, contractual prices are allocated to performance obligations based on estimated relative standalone selling prices of the promised services. For contracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation based on the estimated standalone selling price of the product or service underlying each performance obligation. The standalone selling price represents the amount the Company would sell the product or service to a customer on a standalone basis (i.e., not bundled with any other products or services). The Company's contracts with the U.S. government are subject to the FAR and the price is typically based on estimated or actual costs plus a reasonable profit margin. As a result of these regulations, the standalone selling price of products or services in the Company’s contracts with the U.S. government are typically equal to the selling price stated in the contract. The Company does not contemplate future modifications, including unexercised options until they become legally enforceable. Contracts may be subsequently modified to include changes in specifications, requirements or price, which may create new or change existing enforceable rights and obligations. Depending on the nature of the modification, the Company considers whether to account for the modification as an adjustment to the existing contract or as a separate contract.

In cases where the Company uses the cost-to-cost input method of progress for performance obligations, the extent of progress towards completion is measured based on the proportion of direct costs incurred to date to the total estimated direct costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred. For performance obligations to provide services to the customer, revenue is recognized over time based on direct costs incurred or the right to invoice method (in situations where the value transferred matches the Company’s billing rights) as the customer receives and consumes the benefits.

Significant estimates and assumptions are made in estimating revenue under the cost-to-cost method and total estimated costs, including the estimated contract profit/loss. At the outset of a long-term contract, the Company identifies and monitors risks to the achievement of the technical, schedule and cost aspects of the contract, and assesses the effects of those risks on its estimates of revenue and total costs to complete the contract. The estimates consider the technical requirements, schedule and costs. The initial estimated total costs for each contract considers risks surrounding the ability to achieve the technical requirements, schedule and costs in the initial estimated total costs to complete the contract. Total estimated costs may decrease during the performance of the contract if the Company successfully retires risks surrounding the technical, schedule and cost aspects of the contract. Conversely, total estimated costs may increase if the estimated total costs to complete the contract increase. As a significant change in one or more estimates could affect the profitability of the Company’s contracts, the Company reviews and updates its contract-related estimates regularly. When estimates of total costs at completion for an integrated, construction type contract exceed total estimates of revenue to be earned on a performance obligation related to complex equipment or related services, a provision for the remaining loss on the performance obligation is recognized in the period the loss is determined. Estimated costs are subject to change during the performance period of the contract and may affect the estimated contract loss.

Asset Valuations

The accounting for SWU and uranium inventories includes estimates and judgments. SWU and uranium inventory costs are determined using the average cost method. Inventories of SWU and uranium are valued at the lower of cost or NRV. NRV is the estimated selling price in the ordinary course of business less reasonably predictable costs of completion, disposal, and transportation. The estimated selling price for SWU and uranium under contract is based on the pricing terms of contracts in our Order Book. For uranium not under contract, the estimated selling price is based primarily on published price indicators at the balance sheet date.

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 identifiable intangible assets relate to our Order Book and customer relationships. The Order Book intangible asset is amortized as the Order Book valued at emergence is reduced, principally as a result of deliveries to customers. The customer relationships intangible asset is amortized using the straight-line method over the estimated average useful life of 15 years, with 5 3⁄4 years of scheduled amortization remaining. The aggregate net balance of identifiable intangible assets was $39.4 million as of December 31, 2023.

The carrying values of the intangible assets are subject to impairment tests whenever events or changes in business circumstances indicate that the carrying amount of the intangible assets may not be fully recoverable. The carrying amount of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. An impairment loss is measured as the amount by which the carrying amount of a long-lived asset, or asset group exceeds 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 would cause a change in the results of the tests, which could cause the fair value of the intangible asset to be less than its respective carrying amount.

Pension and Postretirement Health and Life Benefit Costs and Obligations

We provide retirement benefits to certain employees and retirees under defined benefit pension plans and postretirement health and life benefit plans. The valuation of benefit obligations and costs is based on provisions of the plans and actuarial assumptions that involve judgments and estimates.

Assets and obligations related to our retiree benefit plans are remeasured each year as of the balance sheet date resulting in differences between actual and projected results for the year. The Company has elected the accounting option to recognize these actuarial gains and losses in the statement of operations in the fourth quarter. The alternative would be to amortize gains and losses into operating results over time. The Company’s treatment of recognizing actuarial gains and losses immediately is intended to increase transparency into how movements in plan assets and benefit obligations impact financial results. Immediate recognition of such gains and losses in the statement of operations may cause significant fluctuations in our results of operations. In addition, an interim remeasurement and recognition of gains or losses may be required for a plan during the year if lump sum payments exceed certain levels.

Components of retirement benefit expense/income other than service cost are presented in our Consolidated Statements of Operations as Nonoperating Components of Net Periodic Benefit Income. These components consist primarily of the return on plan assets, offset by interest cost as the discounted present value of benefit obligations nears payment. Results also reflect claims experience, changes in mortality and healthcare claim assumptions and changes in market interest rates. Service cost is recognized in Cost of Sales (for the LEU segment) and Selling, General and Administrative expense.

61

Nonoperating Components of Net Periodic Benefit Income netted to income of $23.2 million, $6.6 million, and $67.6 million for the year ended December 31, 2023, 2022, and 2021, including a net actuarial gain of $24.6 million for the year ended December 31, 2023, net actuarial loss of $7.8 million for the year ended December 31, 2022, and net actuarial gain of $50.5 million for the year ended December 31, 2021. For the year ended December 31, 2023, the net actuarial gain reflected favorable investment returns relative to the expected return assumption, partially offset by a decrease in interest rates from approximately 5.5% to 5.2%. For the year ended December 31, 2022, the net actuarial loss reflected unfavorable investment returns relative to the expected return assumption, partially offset by an increase in interest rates from approximately 2.8% to 5.5%, favorable investment returns relative to the expected return assumption, and healthcare claims assumption, partially offset by changes in mortality, healthcare costs trend assumptions, and claims experience. For the year ended December 31, 2021, the net actuarial gain reflected an increase in interest rates from approximately 2.5% to 2.8%, favorable investment returns relative to the expected return assumption, and healthcare claims assumption, partially offset by changes in mortality, healthcare costs trend assumptions, and claims experience.

Changes in actuarial assumptions could impact the measurement of benefit obligations and benefit costs, as follows:

•The expected return on benefit plan assets is approximately 6.8% for 2024. The expected return is based on historical returns and expectations of future returns for the composition of the plans’ equity and debt securities. A one-half percentage point decrease in the expected return on plan assets would increase annual pension costs by $1.3 million in 2024. However, the net impact of any changes in the expected return on benefit plan assets on the final benefit cost recognized for fiscal year 2024 would be $0 since the actual return on assets would effectively be reflected at December 31, 2024, under our mark-to-market accounting methodology.

•The present value of pension obligations is calculated by discounting long-term obligations using a market interest rate. This discount rate is the estimated rate at which the benefit obligations could be effectively settled on the measurement date and is based on yields of high quality fixed income investments whose cash flows match the timing and amount of expected benefit payments of the plan. Discount rates of approximately 5.2% were used as of December 31, 2023. A one-half percentage point reduction in the discount rate would increase the valuation of pension benefit obligations by $13.0 million and postretirement health and life benefit obligations by $3.7 million, and the resulting changes in the valuations would decrease the aggregate service cost and interest cost components of annual pension costs and postretirement health and life benefit costs by $0.9 million and $0.3 million, respectively.

•The healthcare costs trend rates are 7% projected in 2024 reducing to a final trend rate of 5% by 2032. The healthcare costs trend rate represents our estimate of the annual rate of increase in the gross cost of providing benefits. The trend rate is a reflection of health care inflation assumptions, changes in healthcare utilization and delivery patterns, technological advances, and changes in the health status of our plan participants.

Income Taxes

During the ordinary course of business, there are transactions and calculations for which the ultimate tax determination is uncertain. As a result, we recognize tax liabilities based on estimates of whether additional taxes and interest will be due. To the extent that the final tax outcome of these matters is different than the amounts that were initially recorded, such differences will impact the income tax provision in the period in which such determination is made.

Accounting standards prescribe a minimum recognition threshold that a tax position is required to meet before the related tax benefit may be recognized in the financial statements. As of December 31, 2023, the liability for unrecognized tax benefits, included in Other Long-Term Liabilities on the Consolidated Balance Sheet in Part IV of this Annual Report, was $2.9 million and accrued interest and penalties totaled $0.3 million.

62

Accounting for income taxes involves estimates and judgments relating to the tax bases of assets and liabilities and the future recoverability of deferred tax assets. In assessing the realization of deferred tax assets, we determine whether it is more likely than not that the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon generating sufficient taxable income in future years when deferred tax assets are recoverable or are expected to reverse. Factors that may affect estimates of future taxable income include, but are not limited to, competition, changes in revenue, costs or profit margins, market share, and developments related to the American Centrifuge technology. In practice, positive and negative evidence is reviewed with objective evidence receiving greater weight. If, based on the weight of available evidence, it is more likely than not that all, or some portion, of the deferred tax assets will not be realized, we record a valuation allowance. The more negative evidence that exists, the more positive evidence is necessary and the more difficult it is to support a conclusion that a valuation allowance is not needed for all, or some portion, of the deferred tax assets.

All available positive and negative evidence is analyzed quarterly to determine the amount of the valuation allowance. A full valuation allowance against the federal and state net deferred assets was first recorded in the fourth quarter of 2011 because of significant losses and other negative evidence.

In the second quarter of 2020, the valuation allowance on the state net deferred tax assets for the LEU segment was released due to a return to profitability that led to cumulative income for state income tax purposes. A full valuation allowance against the federal and state net deferred tax assets for the rest of the business remained throughout 2020 because negative evidence, including cumulative losses, outweighed positive evidence.

In 2021, Centrus evaluated both positive and negative evidence that was objectively verifiable to determine the amount of the federal valuation allowance that was required on Centrus’ federal deferred tax assets. Centrus considered both its achievement of sustained profitability and cumulative income in 2021, as well as the forecasted income to be significant forms of positive evidence. Negative evidence included uncertainty in and the lack of objectively verifiable evidence for profitability in later years when Centrus’ existing Order Book and supply contracts reach expiration in its LEU segment. In Centrus’ Technical Solutions segment, negative evidence included uncertainty in the future funding of the HALEU enrichment facility and thus, no assumptions for the future funding of the HALEU enrichment facility were included in the forecast model because it was not objectively verifiable. Centrus determined that the positive evidence outweighed the negative evidence and supported a release of the federal valuation allowance. However, due to lack of objectively verifiable information in later years, it was determined that forecasted future income was not sufficient to realize all the deferred tax assets. Therefore, Centrus recorded a $40.7 million partial release of its federal valuation allowance in the fourth quarter of 2021. Based on an analysis of the positive and negative evidence, it was determined that no change to the federal valuation allowance was necessary in 2022.

The Company evaluated both positive and negative evidence that was objectively verifiable to determine the amount of the federal valuation allowance that was required on Centrus’ federal deferred tax assets. Centrus has visibility on a significant portion of revenue in the LEU segment for 2023 through 2026, primarily from its long-term sales contracts. Centrus determined that the positive evidence of increased forecasted future income in the LEU segment based on existing sales Order Book and supply contracts along with commodity market forward pricing indicators, supported the release of the federal valuation allowance. However, due to lack of objectively verifiable information in later years, it was determined that forecasted future income was not sufficient to realize all the deferred tax assets. Therefore, Centrus recorded a partial release of its federal valuation allowance. In the third and fourth quarters of 2023, respectively, Centrus released $7.7 million and $11.7 million of the valuation allowance against its federal net deferred tax assets.

The Company continues to maintain a partial valuation allowance against its remaining federal and state net deferred tax assets due to significant federal and state net operating losses and insufficient future taxable income. As of December 31, 2023, the valuation allowance against the remaining federal and state net deferred tax assets was $382.4 million.

63

Going forward, Centrus will continue to evaluate both positive and negative evidence that would require changes to the remaining federal and state valuation allowances. Such evidence in our Technical Solutions segment may include events that could have a significant impact on pre-tax income, such as signing new contracts with significantly higher or lower margins than currently forecasted, follow-on work related to the HALEU program, or abandonment of the commercial deployment of the centrifuge technology. Refer to Part I, Item 1A, Risk Factors for more information. Such evidence in our LEU segment may include renewing SWU sales contracts with existing customers and/or signing new SWU sales or purchase contracts with significantly higher or lower margins than currently forecasted. Additional evidence in the LEU segment may include potential deferrals in the timing of deliveries requested by its customers, which could impact revenue recognition timing. The impact of these and other potential positive and negative events will be weighed and evaluated to determine if the valuation allowances should be increased or decreased in the future.

Revenue

Revenue from the LEU segment was $269.0 million and $235.6 million for the year ended December 31, 2023 and 2022, respectively, an increase of $33.4 million (or 14%). SWU revenue increased $12.0 million (or 6%) due to a 37% increase in the volume of SWU sold, partially offset by a 23% decrease in the average price of SWU sold. Uranium revenue increased $21.4 million (or 54%). The increase was driven by a 49% increase in the volume of UF6 sold and a 18% increase in the average price of UF6 sold. Revenue from sales of U3O8 was $0 and $4.9 million for the year ended December 31, 2023 and 2022, respectively.

Revenue from the Technical Solutions segment was $51.2 million and $58.2 million for the year ended December 31, 2023 and 2022, respectively, a decrease of $7.0 million (or 12%). This decrease was driven by decreased work performed under the HALEU Demonstration Contract, other contracts, and the X-energy contract of $45.4 million, $4.8 million, and $3.2 million, respectively. This was partially offset by increased work performed under the HALEU Operation Contract of $46.4 million.

Cost of Sales

Cost of sales for the LEU segment was $163.9 million and $105.0 million for the year ended December 31, 2023 and 2022, respectively, an increase of $58.9 million (or 56%). The volume of SWU and UF6 sold increased by 37% and 49%, respectively, and the average SWU and UF6 unit cost increased by 8% and 31%, respectively. Cost of sales of U3O8 was $0 and $3.6 million for the year ended December 31, 2023 and 2022, respectively.

Cost of sales for the Technical Solutions segment was $44.2 million and $70.9 million for the year ended December 31, 2023 and 2022, respectively, a decrease of $26.7 million (or 38%). This decrease was driven by decreased work performed under the HALEU Demonstration Contract, other contracts, and the X-energy contract of $37.6 million, $6.3 million and $3.2 million, respectively. This was partially offset by an increase in work performed under the HALEU Operation Contract of $20.4 million. The costs related to the HALEU Operation Contract for the year ended December 31, 2022 included the $21.3 million accrued loss for Phase 1 of the HALEU Operation Contract. For details on HALEU Operation and Demonstration Contract accounting, refer to Technical Solutions - Government Contracting above.

Gross Profit

The Company recognized a gross profit of $112.1 million and $117.9 million for the year ended December 31, 2023 and 2022, respectively, a decrease of $5.8 million (or 5%).

Gross profit for the LEU segment was $105.1 million and $130.6 million for the year ended December 31, 2023 and 2022, respectively, a decrease of $25.5 million (or 20%). The decrease was due primarily due to the specific contract and pricing mix of SWU contracts and the timing of their deliveries year over year. This was reflected by an increase in the volume of SWU sold and a decrease in the average profit margin per SWU.

Gross profit for the Technical Solutions segment was $7.0 million for the year ended December 31, 2023 and netted to a loss of $12.7 million for the year ended December 31, 2022, a change of $19.7 million (or 155%). The change was attributable to an increase in gross profit generated from the HALEU Operation Contract and other contracts of $26.0 million and $1.5 million, respectively, partially offset by a $7.8 million decrease in gross profit generated from the HALEU Demonstration Contract.

Net Income per Share

Refer to Note 15, Net Income per Common Share, of the Consolidated Financial Statements in Part IV of this Annual Report.

The Company measures Net Income and Net Income per Share both on a GAAP basis and on an adjusted basis to exclude deemed dividends allocable to retired preferred stock shares and the warrant modification (“Adjusted Net Income” and “Adjusted Net Income per Share”). We believe Adjusted Net Income and Adjusted Net Income per Share, which are non-GAAP financial measures, provide investors with additional understanding of the Company’s financial performance as well as its strategic financial planning analysis and period-to-period comparability. These metrics are useful to investors because they reflect how management evaluates the Company’s ongoing operating performance from period-to-period after removing certain transactions and activities that affect comparability of the metrics and are not reflective of the Company’s core operations.

Liquidity and Capital Resources

As of December 31, 2023, the Company had a consolidated cash balance of $201.2 million. In addition, the Company had $29.8 million of restricted cash related to three inventory loans, which each required a cash deposit into an escrow fund. See Note 3, Cash, Cash Equivalents, and Restricted Cash, of the Consolidated Financial Statements in Part IV of this Report. The Company anticipates having adequate liquidity to support our business operations for at least the next 12 months from the date of this Annual Report. Our view of liquidity is dependent on, among other things, conditions affecting our operations, including market, international trade restrictions, sanctions and other conditions, the level of expenditures and government funding for our services contracts, and the timing of customer payments. Liquidity requirements for our existing operations are affected primarily by the timing and amount of customer sales and our inventory purchases.

We believe our Order Book in our LEU segment is a source of stability for our liquidity position. Subject to market conditions, we see the potential for growing uncommitted demand for LEU during the next few years with accelerated open demand in 2025 and beyond.

Cash resources and net sales proceeds from our LEU segment fund technology costs that are outside of our customer contracts in the Technical Solutions segment and general corporate expenses, including cash interest payments on our debt. We believe our investment in advanced U.S. uranium enrichment technology will position the Company to meet the needs of our customers as they deploy advanced reactors and next generation fuels. We signed the three-year HALEU Demonstration Contract with DOE in October 2019. Under the HALEU Demonstration Contract, the Company contributed its required contribution through November 30, 2021. The program began May 31, 2019, when Centrus and the DOE signed a preliminary letter agreement that allowed work to begin while the full contract was being finalized. Our HALEU Demonstration Contract period of performance ended in November 2022. The Company is currently performing closeout activities on the HALEU Demonstration Contract.

We were awarded the HALEU Operation Contract in November 2022 which provided for a 50/50 cost share for Phase 1 of the base contract to complete the cascade, begin operations and complete the initial, small quantity of demonstration HALEU. The Company completed Phase 1 in November 2023. Phase 2 includes continued operations and maintenance on a cost-plus-incentive-fee basis. Finally, the HALEU Operation Contract includes options for the government to unilaterally extend performance for up to an additional nine years, comprised of three options of three years each, also on a cost-plus-incentive-fee basis. The Company also is performing additional work on infrastructure and facility repairs and costs associated with 5B Cylinder refurbishment under the DOE’s technical direction. The Company’s goal is to modularly scale up the facility as demand for HALEU grows in the commercial and government sectors, subject to the availability of funding and/or contracts to purchase the output of the plant.

Although the Company believes 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. For further discussion, refer to Part I, Item 1A, Risk Factors.

If funding of gas centrifuge technology by the U.S. government is reduced or discontinued, or we are not awarded a future DOE contract to continue to operate the cascade, such actions may have a material adverse impact on our ability to deploy the American Centrifuge technology and on our liquidity.

Further, any proposal for a U.S. ban on LEU imports represents a significant risk to our business as we currently rely on the TENEX Supply Contract as the major supply source to meet our delivery obligations. A ban on LEU imports could have a material impact on our operations and liquidity. For further discussion, please see Part I, Item 1A, Risk Factors.

The indenture governing the 8.25% Notes includes restrictions on the ability of Enrichment Corp. to transfer cash and other assets to the Company, which could constrain the Company’s ability to pay dividends on its Common Stock or to fund its commitments or the commitments of its other subsidiaries, subject to certain exceptions, such as the transfer of inventory and other assets in the ordinary course of business of Enrichment Corp. The indenture also restricts the Company’s ability to engage in certain mergers or acquisitions and requires the Company to offer to repurchase all such outstanding notes at 101% of their outstanding principal amount in the event of certain change of control events.

Capital expenditures of approximately $7.0 million are anticipated over the next 12 months.

On October 12, 2023, the Company entered into an agreement with an insurer (“Insurer”) for one of its defined benefit plans to purchase a group annuity contract and transferred approximately $186.5 million of its pension plan obligations to the Insurer. The purchase of the group annuity contract was funded directly by assets of the pension plan of approximately $171.4 million. The purchase resulted in a transfer of benefit administrative responsibilities for approximately 1,400 beneficiaries effective December 1, 2023. The Company recorded income related to the pension settlement in the fourth quarter of $28.6 million which was included in Nonoperating Components of Net Periodic Benefit Income in our Consolidated Statements of Operations.

We are also actively considering, and expect to consider potential strategic transactions from time to time, which at any given time may be in various stages of discussions, diligence, or negotiation. These 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 would seek to satisfy these needs through a combination of working capital, cash generated from operations or additional debt or equity financing.

The change in cash, cash equivalents and restricted cash from our Consolidated Statements of Cash Flows are as follows on a summarized basis (in millions):

Year Ended December 31,

Cash provided by operating activities $ 9.1 $ 20.6

Cash used in investing activities (1.6) (0.7)

Cash provided by (used in) financing activities 13.9 (4.3)

Increase in cash, cash equivalents and restricted cash $ 21.4 $ 15.6

Operating Activities

During 2023, net cash provided by operating activities was $9.1 million. The net increase was primarily due to approximately $318.0 million in cash collected from customers, investment income, and reimbursements for postretirement health and life benefits paid by the Company. These cash inflows were partially offset by approximately $309.0 million of disbursements for operations, of which approximately $245.0 million relates to payments for LEU inventory deliveries and cash outflows for the Technical Solutions segment, with the remaining disbursements including corporate administration, benefits claims, and advanced technology costs.

During 2022, net cash provided by operating activities was $20.6 million. The net increase was primarily due to $252.0 million in cash collected from customers, offset by $159.1 million of payments for LEU inventory deliveries and cash outflows for the Technical Solutions segment. This remaining difference was primarily related to payments for benefit claims, corporate administration, and advance technology costs.

70

Investing Activities

For the year ended December 31, 2023 and 2022, investing activities consisted of capital expenditures of $1.6 million and $0.7 million, respectively.

Financing Activities

For the year ended December 31, 2023, cash of $23.2 million was provided from the net proceeds related to the issuance of 722,568 shares of Class A Common Stock under an ATM offering.

For both the years ended December 31, 2023 and 2022, annual payments of $6.1 million of interest classified as debt are classified as a financing activity. Refer to Note 8, Debt, of the Consolidated Financial Statements in Part IV of this Annual Report regarding the accounting for the 8.25% Notes.

Working Capital

The following table summarizes the Company’s working capital (in millions):

December 31,

Cash and cash equivalents $ 201.2 $ 179.9

Current debt (6.1) (6.1)

Other current assets and liabilities, net (87.3) (84.9)

We are managing our working capital to seek to improve the long-term value of our LEU and Technical Solutions segments and are planning to continue funding the Company’s qualified pension plans because we believe that is in the best interest of all stakeholders. We expect that any other uses of working capital will be undertaken in light of these strategic priorities and will be based on the Company’s determination as to the relative strength of its operating performance and prospects, financial position, and expected liquidity requirements. In addition, we expect that any such other uses of working capital will be subject to compliance with contractual restrictions to which the Company and its subsidiaries are subject, including the terms and conditions of our 8.25% Notes. We continually evaluate alternatives to manage our capital structure, and may opportunistically repurchase, exchange, or redeem Company securities from time to time.

Common Stock Issuance

Pursuant to a sales agreement with its agents, the Company sold through at the market offerings an aggregate of 722,568 shares, 99,090 shares, and 1,516,467 shares of its Class A Common Stock for a total of $24.4 million, $3.8 million, and $44.2 million in 2023, 2022, and 2021, respectively. After expenses and commissions paid to the agents the Company’s 2023, 2022, and 2021, proceeds totaled $23.4 million, $3.6 million, and $42.4 million, respectively. Additionally, the Company recorded direct costs of $0.2 million and $0.3 million related to the issuance in 2023 and 2021, respectively. 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 two prospectus supplements dated December 31, 2020 and December 5, 2022, respectively. The Company has used and/or intends to use the net proceeds from these offerings for working capital and general corporate purposes including, but not limited to, capital expenditures, working capital, investment in technology development and deployment, repayment of indebtedness, potential acquisitions and other business opportunities.

On February 2, 2021, the Company entered into the Voting Agreement Amendment to its existing Voting and Nomination Agreement with the MB Group and an Exchange Agreement, whereby the MB Group agreed to support management’s recommendation on certain matters at the Company’s 2021 Annual Meeting and Kulayba LLC agreed to exchange shares of Preferred Stock for shares of Class A Common Stock and a warrant to acquire additional shares of Class A Common Stock. Pursuant to the First Amendment to the Voting and Nomination Agreement, the MB Group agreed to cause all shares of Class A Common Stock owned of record or beneficially owned by the MB Group at the Annual Meeting to be voted in favor of (i) an amendment to extend the length of the term of the Company’s Section 382 Rights Agreement dated as of April 6, 2016, as amended to date, for two years from June 30, 2021, to June 30, 2023, and (ii) an increase of shares of Class A Common Stock reserved for delivery under the Company’s 2014 Equity Incentive Plan, as amended to date, of an additional 700,000 shares of Class A Common Stock.

In connection with the entry into the Voting Agreement Amendment, the Company and Kulayba LLC also entered into the Exchange Agreement, pursuant to which Kulayba LLC agreed to the Exchange, representing a $5,000,198 liquidation preference (including accrued and unpaid dividends), for (i) 231,276 shares of Class A Common Stock priced at the closing market price of $21.62 on the date the Exchange Agreement was signed and (ii) the Warrant, exercisable for 250,000 shares of Class A Common Stock at an exercise price of $21.62 per share, which 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 Warrant was exercisable by Kulayba LLC for a period commencing on the closing date of the Exchange and ending, unless sooner terminated as provided in the Warrant, on the first to occur of: (a) the second anniversary of the closing date of the Exchange or (b) the last business day immediately prior to the consummation of a Fundamental Transaction (as defined in the Warrant), which results in the shareholders of the Company immediately prior to such Fundamental Transaction owning less than 50% of the voting equity of the surviving entity immediately after the consummation of the Fundamental Transaction. The Company retired the 3,873 shares of Preferred Stock received by the Company under the Exchange Agreement.

On December 29, 2022, the Company amended and restated the Warrant, and entered into a Voting Rights Agreement with the MB Group. Pursuant to the terms of the Voting Rights Agreement, each member of the MB Group and each Permitted Transferee (as defined in the Voting Rights Agreement) agreed, at the Company’s 2023 and 2024 Annual Meetings and at any other vote by the holders of the Company’s Common Stock, to (i) cause, in the case of all Common Stock owned of record, and (ii) instruct and cause the record owner, in the case of all shares of Common Stock of which MB Group is a Beneficial Owner (as defined in the Voting Rights Agreement), but not owned of record, directly or indirectly, by it, or by any MB Affiliate (as defined in the Voting Rights Agreement), as of the applicable record date, in each case entitled to (i) be present for quorum purposes, and (ii) vote, as follows: (a) for all directors nominated by the Board for election, (b) for all other proposals, in accordance with the recommendation of the Board, and (c) for any Company proposed adjournments thereof. In addition, each member of the MB Group agreed to not directly or indirectly gift, sell, dispose or otherwise transfer any shares of Common Stock unless the transferee agreed to be bound to the same voting conditions at the 2023 and 2024 Annual Meetings, and other meetings in 2023 and 2024, except with respect to any sale or disposition of Common Stock on a national securities exchange or any sale or disposition of Common Stock underlying the New Warrant to any person that is not affiliated, associated or otherwise related to any member of the MB Group. In exchange, the Company agreed to amend and restate that Warrant, to extend the term of the Warrant to February 5, 2024, subject to the other terms of the Warrant (as so amended and restated, the New Warrant). Immaterial amendments were made on October 17, 2022.

On December 18, 2023, the Company issued 149,179 net shares of Class A Common Stock in connection with the cashless exercise by Kulayba LLC of the New Warrant for 250,000 shares of Class A Common Stock at an exercise price of $21.62.

2023 Shelf Registration

The Company filed a shelf registration statement on Form S-3 (Registration Statement No. 333-272984) with the SEC on June 28, 2023, which became effective on July 10, 2023. Pursuant to this shelf registration statement, the Company may offer and sell up to $200 million in securities, in aggregate. The Company retains broad discretion over the use of the net proceeds from the sale of the securities offered. Unless otherwise specified in any prospectus supplement, we currently intend to use the net proceeds from the sale of our securities offered under this prospectus for working capital and general corporate purposes including, but not limited to, capital expenditures, working capital, repayment of indebtedness, potential acquisitions and other business opportunities. Pending any specific application, we may initially invest funds in short-term marketable securities or apply them to the reduction of indebtedness.

Rights Agreement

On June 20, 2023, the Company entered into a Fifth Amendment to the Rights Agreement, which amends the Rights Agreement, dated as of April 6, 2016, by and among the Company, and Computershare Trust Company, N.A. and Computershare Inc., as rights agent, as amended by (i) the First Amendment to the Rights Agreement dated as of February 14, 2017, (ii) the Second Amendment to the Rights Agreement dated as of April 3, 2019, (iii) the Third Amendment to the Rights Agreement dated as of April 13, 2020, and (iv) the Fourth Amendment to the Rights Agreement dated as of June 16, 2021.

The Fifth Amendment to the Rights Agreement (i) increases the purchase price for each one one-thousandth (1/1000th) of a share of the Company’s Series A Participating Cumulative Preferred Stock, par value $1.00 per share, from $18.00 to $160.38; and (ii) extends the Final Expiration Date (as defined in the Rights Agreement) from June 30, 2023 to June 30, 2026.

The Fifth Amendment was not adopted as a result of, or in response to, any effort to acquire control of the Company. The Fifth Amendment has been adopted in order to preserve for the Company’s stockholders the long-term value of the Company’s net operating loss carryforwards for United States federal income tax purposes and other tax benefits.

Capital Structure and Financial Resources

Interest on the 8.25% Notes is payable semi-annually in arrears as of February 28 and August 31 based on a 360-day year consisting of twelve 30-day months. The 8.25% Notes are guaranteed on a subordinated and limited basis by, and secured by substantially all assets of, Enrichment Corp. The 8.25% Notes mature on February 28, 2027. Additional terms and conditions of the 8.25% Notes are described in Note 8, Debt, of the Consolidated Financial Statements in Part IV of this Annual Report.

2021 Tender Offer

On October 20, 2021, the Company announced the commencement of a tender offer to purchase all of its outstanding Series B Senior Preferred Stock, par value $1.00 per share (the “Series B Senior Preferred Stock”), at a price of $1,145.20 per share (inclusive of any rights to accrued but unpaid dividends), to the sellers in cash, less any applicable withholding taxes (the “Offer”). The Offer was made pursuant to the Tender Offer Statement on Schedule TO filed by the Company on October 20, 2021, with the SEC. The aggregate liquidation preference per Series B Senior Preferred Stock (including accrued but unpaid dividends) was $1,347.29 as of September 30, 2021.

73

On November 23, 2021, the Company announced the results of the tender offer and the related Consent Solicitation to amend the certificate of designation of the Series B Senior Preferred Stock (the “Series B Preferred Amendment”). 36,867 shares of the Series B Senior Preferred Stock were properly tendered and not properly withdrawn in the Offer, and corresponding consents have been delivered in the Consent Solicitation. Pursuant to the terms of the Offer and Consent Solicitation, the Company has accepted for purchase all of the Series B Senior Preferred Stock tendered in the Offer, for an aggregate purchase price of $42.2 million. The accepted shares represent 97.4% of the Company’s outstanding Series B Senior Preferred Stock as of September 30, 2021. Based on the final results, the requisite consent of at least 90% of the outstanding Series B Senior Preferred Stock required to approve the Series B Preferred Amendment was obtained. On November 23, 2021, the Company issued a Notice of Full Redemption providing for the redemption of any and all shares 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.

The effect of the Series B Preferred Amendment was to: (i) cease any obligation to pay dividends on Series B Senior Preferred Stock (other than the payment of accrued dividends in connection with a redemption or distribution of assets upon liquidation, dissolution or winding up), (ii) permit the Company to redeem Series B Senior Preferred Stock during the 90 days following the date of effectiveness of the Series B Preferred Amendment at a redemption price per share equal to $1,145.20 (plus any additional accrued dividends for the period from and including the date of effectiveness of the Series B Preferred Amendment to the date of redemption), (iii) remove the prohibition on the declaration and payment of dividends on junior stock of the Company, which includes all shares of the Company’s capital stock defined as “Common Stock” in the Company’s Amended and Restated Certificate of Incorporation, or the redemption, purchase or acquisition of such junior stock, and (iv) remove the restriction on redemption, purchase or acquisition of capital stock of the Company ranking on parity with the Series B Senior Preferred Stock.

On December 16, 2021, the Company filed a Certificate of Elimination of the Series B Senior Preferred Stock of Centrus Energy Corp. with the Secretary of State of Delaware to eliminate the designation of the Series B Senior Preferred Stock and to return all shares of preferred stock of the Company previously designated as Series B Senior Preferred Stock to authorized but unissued and undesignated shares of preferred stock of the Company.

Contractual Commitments

As of December 31, 2023, Centrus had contractual commitments to repay debt, make payments under operating leases, settle obligations related to agreements to purchase goods and services and settle tax and other liabilities.

Centrus has obligations related to our 8.25% Notes that mature in February 2027, as discussed above. We are also obligated to make payments under operating leases that expire at various dates through 2027. Refer to Note 9, Leases, of the Consolidated Financial Statements in Part IV of this Annual Report for further information.

In our Technical Solutions segment, the majority of our contractual commitments were entered into as a result of contracts we have with our U.S. government customers. The U.S. government generally would be required to pay us for any costs we incur relative to these commitments if they were to terminate the related contracts “for convenience” under the FAR, subject to available funding. This also would be true in cases where we perform subcontract work for a prime contractor under a U.S. government contract. The termination for convenience language also may be included in contracts with foreign, state and local governments. We also have contracts with customers that do not include termination for convenience provisions, including contracts with commercial customers.

74

In our LEU segment, we have long-term inventory purchase agreements with TENEX and Orano that extend to 2028 and 2030, respectively. Refer to Note 17, Commitments and Contingencies, of the Consolidated Financial Statements in Part IV of this Annual Report for additional information. In addition, Centrus has entered into multiple inventory loans that we expect to repay from 2024 through 2026. Refer to Note 4, Inventories, of the Consolidated Financial Statements in Part IV of this Annual Report for additional information.

DOE Technology License

We have a non-exclusive license in DOE inventions that pertains to enriching uranium using gas centrifuge technology. The license agreement with the DOE provides for annual royalty payments based on a varying percentage (1% up to 2%) of our annual revenues from sales of the SWU component of LEU produced by the Company using DOE centrifuge technology. There is a minimum annual royalty payment of $100,000 and the maximum cumulative royalty over the life of the license is $100 million. There is currently no commercial enrichment facility producing LEU using DOE centrifuge technology. We are continuing to advance our U.S. centrifuge technology that has evolved from DOE inventions at specialized technology and manufacturing facilities in Oak Ridge with a view to deploying a commercial enrichment facility over the long term once market conditions recover.

Off-Balance Sheet Arrangements

Other than our SWU purchase commitments and the license agreement with the DOE relating to the American Centrifuge technology, there were no material off-balance sheet arrangements at December 31, 2023.

New Accounting Standards

Reference is made to New Accounting Standards in Note 1, Summary of Significant Accounting Policies, of the Consolidated Financial Statements in Part IV of this Annual Report for information on new accounting standards.

Item 7A.Quantitative and Qualitative Disclosures About Market Risk

We do not use derivative financial instruments for speculative trading purposes, nor do we currently hedge our exposure to any market risk.

Interest Rate Risk

We have financial instruments that are subject to interest rate risk, primarily our 8.25% Notes. As of December 31, 2023, we have $95.7 million of debt related to our 8.25% Notes, with a fair value of approximately $71.7 million. The terms of our 8.25% Notes do not generally allow investors to demand we pay off these obligations prior to maturity. Therefore, we do not have significant exposure to interest rate risk on our 8.25% Notes. However, we do have exposure to fair value risk if we repurchase or exchange the 8.25% Notes prior to maturity.

Inflation Risk

The global macroeconomic environment has experienced, and continues to experience, extraordinary challenges, including the highest rates of inflation in recent years. These macroeconomic factors have contributed, and we expect will continue to contribute, to increased costs, among other concerns. We cannot predict how long these inflationary pressures will continue, or how they may change over time, but we expect to see continued impacts on the global economy, our customers, our industry and our company.

We have generally been able to anticipate increases in costs when pricing our contracts. In our Technical Solutions segment, contracts typically include assumptions for labor, material, and overhead cost escalations and are typically executed on a cost-plus basis. In our LEU segment, bids for longer-term contracts typically include assumptions for shipping and handling cost escalations in amounts that historically have been sufficient to cover cost increases over the delivery periods.

Foreign Currency Exchange Rate Risk

Our contracts with customers and suppliers are denominated primarily in U.S. dollars. On occasion, we will accept payments in euros for spot sales that may be subject to short-term exchange risk. Half of our Orano Supply Agreement is denominated in euros, exchanged at a fixed rate. We have one customer contract that commenced deliveries in 2023 and extends to 2026 where payments are denominated in euros that may be subject to exchange rate risk. If the euro strengthens against the dollar by approximately 20% and nears its highest value over the past 10 years, it will have a negative cash flow impact on the contract of less than 10%. Since the substantial majority of our business is conducted in U.S. dollars, a 20% change in the euro would not have a material impact to our financial condition or results of operations.

Commodity Price Risk

Commodity price risk is associated with price movements resulting from changes in supply and demand, fuel costs, market liquidity, weather conditions, governmental regulatory and environmental policies, and other factors. Centrus procures SWU and uranium through long-term and short-term contracts as well as spot market purchases. Similarly, Centrus sells SWU and uranium through long-term and short-term contracts as well as spot sales. The Company’s purchase agreements are subject to fluctuations in market prices. Prices for the Company’s purchase agreements are generally determined by formulas using a combination of fixed and market-related pricing with more favorable pricing on the fixed price component as well as a pricing ceiling for the market-related component on its Orano Supply Agreement. Furthermore, the Company also has a substantial portion of its purchase order book committed under fixed price sales agreements with more recent arrangements reflecting higher market pricing based upon improved market conditions. As such, the Company believes any changes in the prices of SWU and uranium do not create material market risk as the Company has a natural hedge in its purchase arrangements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the stockholders and the Board of Directors of Centrus Energy Corp.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of Centrus Energy Corp. and subsidiaries (the "Company") as of December 31, 2023, the related consolidated statements of operations and comprehensiveincome, stockholders’ deficit, and cash flows, for the year ended December 31, 2023, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023, and the results of its operations and its cash flows for the year ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 9, 2024, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Valuation Allowance related to Federal Deferred Tax Assets – Refer to Notes 1 and 14 to the financial statements

Critical Audit Matter Description

The Company evaluated both positive and negative evidence that was objectively verifiable to determine the amount of the federal valuation allowance that was required on Centrus’ federal deferred tax assets. Centrus has visibility on a significant portion of revenue in the LEU segment for 2023 through 2026, primarily from its long-term sales contracts. Centrus determined that the positive evidence of increased forecasted future income in the LEU segment based on existing sales Order Book and supply contracts along with commodity market forward pricing indicators, supported the release of the federal valuation allowance. However, due to lack of objectively verifiable information in later years, it was determined that forecasted future income was not sufficient to realize all the deferred tax assets. Therefore, Centrus recorded a partial release of its federal valuation allowance. In the third and fourth quarters of 2023, respectively, Centrus released ($7.7) million and ($11.7) million of the valuation allowance against its federal net deferred tax assets.

The principal considerations for our determination that performing procedures relating to the valuation allowance related to federal deferred tax assets is a critical audit matter are (i) the significant judgment by management when assessing the ability to realize the federal deferred tax assets and whether a valuation allowance is necessary, particularly as it relates to estimates of future taxable income and (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating audit evidence related to management’s significant assumptions related to estimates of future taxable income.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the Valuation Allowance related to Federal Deferred Tax Assets included the following, among others:

•Tested the design and operating effectiveness of management’s internal controls pertaining to the ability to realize federal deferred tax assets and whether a valuation allowance is necessary, including controls over the estimates of future taxable income.

•Evaluated management’s methodology for assessing the ability to realize federal deferred taxes and whether a valuation allowance is necessary.

•Tested the completeness and accuracy of underlying information used in management’s process for assessing the ability to realize federal deferred tax assets and whether a valuation allowance is necessary.

•Assessed the timing for appropriateness of the valuation allowance partial releases associated with the federal deferred tax assets.

•Evaluating management’s assumption related to the estimates of future taxable income involved evaluating whether the assumptions and estimates used by management were reasonable considering (i) the current and past performance of the Company; (ii) the terms of the Company’s existing contractual agreements with its customers and suppliers; (iii) the source and reliability of market related inputs; and (iv) whether the assumptions were consistent with evidence obtained in other areas of the audit.

•Read and analyzed the minutes of the Boards of Directors of Centrus Energy Corporation for discussions of changes in legal, regulatory, or business factors which could impact management’s estimates and conclusions with respect to the financial statement impacts of the valuation allowance for deferred tax assets.

•Read and evaluated relevant sanctions, laws, regulatory statutes or other publicly available information to assess whether this external information was appropriately considered by management in their determination of the valuation allowance related to federal deferred tax assets.

•Evaluated Centrus Energy Corporation’s footnotes and disclosures related to the financial statement impacts of the valuation allowance for deferred tax assets.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the stockholders and the Board of Directors of Centrus Energy Corp.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Centrus Energy Corp. and subsidiaries (the “Company”) as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2023, of the Company and our report dated February 9, 2024, expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Principles of Consolidation

The Consolidated Financial Statements of Centrus Energy Corp. (“Centrus” or the “Company”), which include the accounts of the Company, its principal subsidiary Enrichment Corp., and its other subsidiaries, were prepared in conformity with U.S. GAAP. Certain prior year amounts have been reclassified for consistency with the current year presentation. All material intercompany transactions have been eliminated.

Use of Estimates

The preparation of Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts presented and disclosed in the Consolidated Financial Statements. Significant estimates and judgments include, but are not limited to, revenue and related costs, asset valuations, pension and postretirement health and life benefit costs and obligations, the tax bases of assets and liabilities, the future recoverability of deferred tax assets, and determination of the valuation allowance for deferred tax assets. Actual results may differ from such estimates, and estimates may change if the underlying conditions or assumptions change.

Cash and Cash Equivalents

Cash and cash equivalents include short-term or highly liquid assets with original maturities of three months or less.

Inventories and Inventories Owed to Customers and Suppliers

LEU consists of two components: SWU and UF6. SWU is a standard unit of measurement that represents the effort required to transform a given amount of natural uranium into two components: 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 hexafluoride deemed to be used in the production of LEU under this formula is referred to as its uranium or “feed” component.

SWU and uranium inventory costs are determined using the average cost method. SWU and uranium purchase costs include shipping costs when applicable. Inventories of SWU and uranium are valued at the lower of cost or NRV. NRV is the estimated selling price in the ordinary course of business less reasonably predictable costs of completion, disposal, and transportation. The estimated selling price for SWU and uranium is based on the pricing terms of contracts in the Company’s Order Book, and, for uranium not under contract, the estimated selling price is based primarily on published price indicators at the balance sheet date.

101

Inventories owed to customers and suppliers, included in current liabilities, consist primarily of SWU and uranium inventories owed to fabricators. Fabricators process LEU into fuel for use in nuclear reactors. Under inventory optimization arrangements between Centrus and domestic fabricators, fabricators order quantities of LEU from Centrus based on scheduled or anticipated orders from utility customers, for deliveries in future periods. As delivery obligations under actual customer orders arise, Centrus typically satisfies these obligations by arranging for the transfer to the customer of title to the specified quantity of LEU at the fabricator. Centrus’ balances of SWU and uranium vary over time based on the timing and size of the fabricator’s LEU orders from Centrus and the fabricator’s needs for working stock of LEU. Balances can be positive or negative at the discretion of the fabricator. Fabricators have other inventory supplies and, where a fabricator has elected to order less material from Centrus than Centrus is required to deliver to its customers at the fabricator, the fabricator will use these other inventories to satisfy Centrus’ customer order obligations on Centrus’ behalf. In such cases, the transfer of title of LEU from Centrus to the customer results in quantities of SWU and uranium being owed by Centrus to the fabricator. The amounts of SWU and uranium owed to fabricators are satisfied as future deliveries of LEU to fabricators are made.

Deferred Taxes

Centrus follows the asset and liability approach to account for deferred taxes. Deferred tax assets and liabilities are recognized for the anticipated future tax consequences of temporary differences between the balance sheet carrying amounts of assets and liabilities and their respective tax bases. Deferred taxes are based on income tax rates in effect for the years in which temporary differences are expected to reverse. The effect on deferred taxes of a change in income tax rates is recognized in income when the change in rates is enacted in the law. A valuation allowance is provided if it is more likely than not that all, or some portion, of the deferred tax assets may not be realized.

Property, Plant and Equipment

Property, plant and equipment are recorded at acquisition cost. Leasehold improvements and machinery and equipment are depreciated on a straight-line basis over the shorter of the useful life of the assets or the lease term, if applicable. Refer also to Carrying Value of Long-Lived Assets below.

Intangible Assets

Centrus has intangible assets resulting from fresh start accounting as a result of emergence from Chapter 11 bankruptcy on September 30, 2014. The identifiable intangible assets relate to the sales Order Book and customer relationships. The Order Book intangible asset is amortized as the Order Book valued at emergence is reduced, principally as a result of deliveries to customers. The customer relationships intangible asset is amortized using the straight-line method over the estimated average useful life of 15 years, with 5 3⁄4 years of scheduled amortization remaining. Refer also to Carrying Value of Long-Lived Assets below.

Carrying Value of Long-Lived Assets

The Company evaluates the carrying values of property, plant and equipment and identifiable intangible assets when events or changes in business circumstances indicate that the carrying amount of asset, or asset group, may not be fully recoverable. The carrying amount of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. An impairment loss is measured as the amount by which the carrying amount of a long-lived asset, or asset group, exceeds its fair value.

102

Financial Instruments and Fair Value Measurement

Accounting standards define fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, consideration is given to the principal or most advantageous market and assumptions that market participants would use when pricing the asset or liability.

Pursuant to accounting standards, Centrus’ 8.25% Notes due February 2027 are recorded at face value and the fair value is disclosed. The estimated fair value of the 8.25% Notes is based on bid/ask quotes as of or near the balance sheet date. Debt issuance costs are deferred and amortized over the life of the instrument.

The balance sheet carrying amounts for accounts receivable, accounts payable and accrued liabilities, and payables under inventory purchase agreements approximate fair value because of the short-term nature of the instruments.

Concentrations of Credit Risk

Credit risk could result from the possibility of a customer failing to perform or pay according to the terms of a contract. Extension of credit is based on an evaluation of each customer’s financial condition. Centrus regularly monitors credit risk exposure and takes steps intended to mitigate the likelihood of such exposure resulting in a loss.

Concentrations of Supply Risk and Other Considerations with the 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 the Company’s largest source and accounts for well over one-half of or its anticipated supply in 2024-2027 for deliveries to U.S. customers.

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.Canada has imposed sanctions on ocean transportation of Russian LEU, but has given a permit to the Company’s carrier that extends to early July 2024. Additional sanctions or other measures by the U.S. or foreign governments (including the Russian government) could be imposed or the existing Canadian permit might not be extended. Any sanctions or measures directed at trade in LEU from Russia or the parties involved in such trade or otherwise,including denial or non-renewal of licenses or permits, 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 there are proposals in Congress (including one that has passed the House of Representatives) to impose a ban on imports of Russian LEU.

If a ban were enacted or 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, the Company’s alternative sources are not sufficient to replace all of the Russian LEU the Company is currently permitted to import under the RSA, and to the extent additional supply cannot be obtained, or obtained at a higher costs, it will have a material adverse impact on its business, results of operations, and competitive position.

103

Given the foregoing, 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 and well as on our business, results of operations, and competitive position.

Segments

Centrus operates two business segments: LEU, which supplies various components of nuclear fuel to utilities, and Technical Solutions, which provides advanced engineering, design, and manufacturing services to government and private sector customers.

Related Party

As previously disclosed in the Company’s Current Report on Form 8-K filed on December 31, 2020, on that same date the Company entered into an At Market Sales Agreement (the “Sales Agreement”) with B. Riley Securities, Inc. and Lake Street Capital Markets, LLC, relating to an ATM offering of shares of the Company’s Class A Common Stock. Mr. Williams, Chairman of the Centrus Board of Directors, also served on the board of B. Riley Financial, Inc. Mr. Williams recused himself and took no part in the selection of B. Riley or the negotiation of the terms of the Sales Agreement.

The Company filed a shelf registration statement on Form S-3 (Registration Statement No. 333-272984) with the SEC on June 28, 2023, which became effective on July 10, 2023. Pursuant to this shelf registration statement, the Company may offer and sell up to $200 million in securities, in aggregate. The Company may continue to work with B. Riley Securities, Inc. for any offerings under this registration statement. Mr. Williams is an employee of Targus International LLC whose ultimate parent has been B. Riley Financial, Inc since 2022. Please refer to Note 16, Stockholders’ Equity, for further details.

Foreign Currency

The Company records foreign currency transaction gains and losses, realized and unrealized, and foreign exchange gains and losses due to re-measurement of monetary assets and liabilities that are not denominated in U.S. dollars in other income, net in the Consolidated Statements of Operations.

Revenue

The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Revenue for product and service sales is recognized when or as the Company transfers control of the promised products or services to the customer. Revenue is measured at the transaction price, which is based on the amount of consideration that the Company expects to receive in exchange for transferring the promised goods or services to the customer. The transaction price will include estimates of variable consideration until it is probable that a significant reversal of revenue recognized will not occur.

SWU and Uranium Revenue

Revenue for the Company’s LEU segment is derived from sales of the SWU component of LEU, from sales of both the SWU and uranium components of LEU, and from sales of UF6 and U308. Contracts with customers are primarily medium and long-term, fixed-commitment, contracts under which its customers are obligated to purchase a specified quantity of the SWU component of LEU or the SWU and uranium components of LEU. The Company’s contracts for UF6 and U308 are generally shorter-term, fixed-commitment contracts.

104

Revenue is recognized at the time the customer obtains control of the LEU or uranium. Customers generally obtain control of LEU at nuclear fuel fabricators. Centrus ships LEU to nuclear fuel fabricators for scheduled or anticipated orders from utility customers. Based on customer orders, Centrus arranges for the transfer of title of LEU from Centrus to the customer for the specified quantity of LEU at the fuel fabricator. Each such delivery to a customer is accounted for as a distinct performance obligation under a contract, and a contract may call for multiple deliveries over a number of periods. The contract’s transaction price is allocated to each performance obligation based on the observable standalone selling price of each distinct delivery of SWU or uranium. For certain contracts the customers may elect not to take control of the LEU or uranium and Centrus may have the right to enforce payment under the terms of the contractual agreement. The revenue recognition for these contracts is assessed when it occurs.

Utility customers in general have the option to defer receipt of uranium products purchased from the Company beyond the contractual sale period. In such cases, title to SWU and/or uranium components are transferred to the customer and a performance obligation for Centrus is created and a receivable is recorded. Cash is collected for the receivable under normal credit terms. The performance obligation is represented as deferred revenue in Deferred Revenue and Advances from Customers on the Consolidated Balance Sheet and the customer-titled product is classified as Deferred Costs Associated with Deferred Revenue on the Consolidated Balance Sheet. Risk of loss remains with Centrus until the customer obtains control of the uranium product. The recognition of revenue and related cost of sales occurs at the point in time at which the customer obtains control of SWU or uranium and risk of loss of the product transfers to the customer, which may occur beyond one year. The timing of the transfer of control, subject to notice period requirements, is at the option of the customer. As such, deferred costs and deferred revenue are classified within current assets and current liabilities, respectively.

On occasion, the Company will accept payment in the form of uranium. Revenue from the sale of SWU under such contracts is recognized at the time transfer of control of LEU occurs and is based on the fair value of the uranium at contract inception or, as the quantity of uranium is finalized, if variable.

Amounts billed to customers for handling costs are included in sales. Handling costs are accounted for as a fulfillment cost and are included in cost of sales. The Company does not have shipping costs associated with outbound freight after control over a product has transferred to a customer. The Company’s contracts with customers do not provide for significant payment terms or financing components.

Technical Solutions Revenue

Revenue for the Technical Solutions segment, principally representing technical, manufacturing, engineering, procurement, construction and operations services offered to public and private sector customers, is recognized over the contractual period as services are rendered. The Company recognizes revenue over time as it performs on these contracts because of the continuous transfer of control to the customer. For public sector contracts, this continuous transfer of control to the customer is supported by clauses in the contract that allow the customer to unilaterally terminate the contract for convenience, pay the Company for costs incurred plus a reasonable profit and assume control of any work in progress. The Company’s government and private sector contracts generally contain contractual termination clauses or entitle the Company to payments for work performed to date for goods and services that do not have an alternative use. With control transferring over time, revenue is recognized based on the extent of progress towards completion of the performance obligation. A contract may contain one or more performance obligations. Two or more promises to transfer goods or services to a customer may be considered a single performance obligation if the goods or services are highly interdependent or highly interrelated such that utility of the promised goods or services to the customer includes integration services provided by the Company.

105

The Company determines the transaction price for each contract based on the consideration it expects to receive for the products or services being provided under the contract. If transaction prices are not stated in the contract for each performance obligation, contractual prices are allocated to performance obligations based on estimated relative standalone selling prices of the promised services. For contracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation based on the estimated standalone selling price of the product or service underlying each performance obligation. The standalone selling price represents the amount the Company would sell the product or service to a customer on a standalone basis (i.e., not bundled with any other products or services). The Company's contracts with the U.S. government are subject to the FAR and the price is typically based on estimated or actual costs plus a reasonable profit margin. As a result of these regulations, the standalone selling price of products or services in the Company’s contracts with the U.S. government are typically equal to the selling price stated in the contract. The Company does not contemplate future modifications, including unexercised options until they become legally enforceable. Contracts may be subsequently modified to include changes in specifications, requirements or price, which may create new or change existing enforceable rights and obligations. Depending on the nature of the modification, the Company considers whether to account for the modification as an adjustment to the existing contract or as a separate contract.

The Company generally uses the cost-to-cost input method of progress for performance obligations to deliver products with continual transfer of control to the customer because it best depicts the transfer of control to the customer that occurs as the Company incurs costs. Under the cost-to-cost method, the extent of progress towards completion is measured based on the proportion of direct costs incurred to date to the total estimated direct costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred. For performance obligations to provide services to the customer, revenue is recognized over time based on direct costs incurred or the right to invoice method (in situations where the value transferred matches the Company’s billing rights) as the customer receives and consumes the benefits.

Use of the cost-to-cost method requires the Company to make reasonably dependable estimates of costs at completion associated with the design, manufacture and delivery of products and services in order to calculate revenue. Significant judgment is used to estimate total revenue and costs at completion, particularly in the assumptions related to internal labor hours and third-party services for which a vendor invoice or quote is not yet available. As a significant change in one or more estimates could affect the profitability of the Company’s contracts, the Company reviews and updates its contract-related estimates regularly. Adjustments in estimated profits/losses are recognized under the cumulative catch-up method. Under this method, the impact of the adjustments is recognized in the period the adjustment is recognized. When estimates of total costs at completion for such an integrated, construction type contract exceed total estimates of revenue to be earned on a performance obligation related to complex equipment or related services, a provision for the remaining loss on the performance obligation is recognized in the period the loss is determined.

The Company applied the practical expedient in paragraph ASC 606-10-50-14 and does not disclose the value of remaining performance obligations under service contracts having original expected terms of one year or less.

The timing of revenue recognition may differ from the timing of invoicing to customers. Progress on satisfying performance obligations under contracts with customers and the related billings and cash collections are recorded on the Consolidated Balance Sheet as contract assets or contract liabilities. Contract balances are classified as assets or liabilities on a contract-by-contract basis at the end of each reporting period.

Unbilled receivables are included in Accounts Receivable on the Consolidated Balance Sheet and arise when the timing of cash collected from customers differs from the timing of revenue recognition. Those assets are recognized when the revenue associated with the contract is recognized prior to billing and derecognized when billed in accordance with the terms of the contract. To the extent billings to the customer precede the recognition of Technical Solutions revenue, the Company recognizes a liability included in Deferred Revenue and Advances from Customers on the Consolidated Balance Sheet.

106

Advanced Technology Costs

American Centrifuge and related expenses that are outside of the Company’s customer contracts are included in Advanced Technology Costs.

Pension and Postretirement Health and Life Benefit Plans

The Company provides retirement benefits to certain employees and retirees under defined benefit pension plans and postretirement health and life benefit plans. The valuation of benefit obligations and costs is based on provisions of the plans and actuarial assumptions that involve judgments and estimates. Plan assets and benefit obligations are remeasured each year as of the balance sheet date, or when lump sum payments exceed certain levels, resulting in differences between actual and projected results. The Company has elected to recognize these actuarial gains and losses immediately in the statement of operations to provide transparency regarding the impacts of changes in plan assets and benefit obligations.

Executive Severance Plan

The Company provides severance benefits to certain covered executives, which may also include continuation of certain insurance benefits, under an Executive Severance Plan (the “Severance Plan”). The benefits payable under the Severance Plan are based on salary level, amongst other variables. As the severance expenses are part of an on-going benefit arrangement, the Company recognizes the expense when payment of the severance is probable and can be reasonably estimated in accordance with ASC 712, Compensation — Nonretirement Postemployment Benefits.

Stock-Based Compensation

Centrus has a stock-based compensation plan which authorizes the issuance of common stock to the Company’s employees, officers, directors, and other individuals providing services to the Company or its affiliates pursuant to options, notional stock units, stock appreciation rights, restricted stock units, restricted stock, performance awards, dividend equivalent rights, and other stock-based awards.

Stock-based compensation cost for options and stock-settled awards are measured at the grant date based on the fair value of the award. The cost is recognized over the requisite service period on a straight-line basis over the vesting period.

Stock-based compensation cost for awards likely to be settled with cash payments is recognized over the requisite service period and accrued as a liability and re-measured each reporting period based on the trading price of the Company’s common stock.

The Company recognizes forfeitures as they occur.

New Accounting Standards

Accounting Standards Effective in Future Periods

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") 2023-07, Segment Reporting, to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This pronouncement is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 and early adoption is permitted. The Company is evaluating the impact this will have on its Consolidated Financial Statements.

107

In December 2023, the FASB issued ASU 2023-09, Income Taxes, to improve the transparency of income tax disclosures, primarily through requiring consistent categories and greater disaggregation in the rate reconciliation and requiring disaggregation of income taxes paid by jurisdiction. This pronouncement is effective for fiscal years beginning after December 15, 2024 and early adoption is permitted. Based on the Company’s review, it does not expect the pronouncement to have any material impact on its Consolidated Financial Statements.

The following table presents revenue from SWU and uranium sales disaggregated by geographical region, including foreign countries representing 10% or more of revenue, based on the billing addresses of customers (in millions):

Source: SEC EDGAR (public domain) · 10-K for the period ended 2023-12-31, filed 2024-02-09 · accession 0001065059-24-000013

Filing HTML rendered to line-structured narrative text by the shipped reducer (datafeeds.edgar_fulltext.visible_text, keep_table_headers=True): scripts and inline-XBRL headers are dropped, and table content is reduced to its short label cells — numeric table data is not rendered and is therefore not counted. The same rendering is used for every year, so a year-over-year comparison is like for like.

The text is our rendering of the filing, not a facsimile: original pagination, typography and tables are not reproduced, and the numbers live in the financial statements (FA).

The outline locates item HEADINGS in this document. Only Items 1A and 7 have certified boundaries elsewhere in the terminal (the redline and the narrative-overlap number); every span here runs from one heading found to the next heading found.

How the outline was chosen. It is the longest chain of item headings that runs forward through both the document and the standard item order: 23 headings are on that chain and 17 further heading-shaped lines are not — the table-of-contents echo of every item, cross-references and exhibit-list mentions. Each entry's length is measured from its heading to the next heading on the chain.
