FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q, including Management’s Discussion and Analysis of Financial Condition and Results of Operations in Part I, Item 2, contains “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934. In this context, forward-looking statements mean statements related to future events, may address our expected future business and financial performance, and often contain words such as “expects”, “anticipates”, “intends”, “plans”, “believes”, “will”, “should”, “could”, “would” or “may” and other words of similar meaning. Forward-looking statements by their nature address matters that are, to different degrees, uncertain.

For Centrus Energy Corp., particular risks and uncertainties that could cause our actual future results to differ materially from those expressed in our forward-looking statements include but are not limited to the following which are, and will be, exacerbated by the novel coronavirus (“COVID-19”) pandemic and subsequent variants, and any worsening of the global business and economic environment as a result; risks related to the war in Ukraine and geopolitical conflicts and the imposition of sanctions or other measures imposed by either the U.S. or foreign governments, organizations (including the United Nations, the European Union or other international organizations), entities or persons, that could directly or indirectly impact our ability to obtain or sell low enriched uranium (“LEU”) under our existing supply contract with the Russian government-owned entity TENEX, Joint-Stock Company (“TENEX”); risks related to the refusal of TENEX to deliver LEU to us if TENEX is unable to receive payments, receive the return of natural uranium, as a result of any government, international or corporate actions or directions or other reasons; risks related to natural and other disasters, including the continued impact of the March 2011 earthquake and tsunami in Japan on the nuclear industry and on our business, results of operations and prospects; risks related to financial difficulties experienced by customers or suppliers, including possible bankruptcies, insolvencies or any other inability to pay for our products or services or delays in making timely payment; risks related to pandemics, endemics, and other health crises; risks related to the impact and potential extended duration of a supply/demand imbalance in the market for LEU; risks related to our ability to sell the LEU we procure pursuant to our purchase obligations under our supply agreements including those imposed under the 1992 Russian Suspension Agreement as amended, international trade legislation and other international trade restrictions; risks related to existing or new trade barriers and contract terms that limit our ability to procure LEU for, or deliver LEU to customers; risks related to pricing trends and demand in the uranium and enrichment markets and their impact on our profitability; risks related to the movement and timing of customer orders; risks related to our dependence on others, such as our transporters, for deliveries of LEU including deliveries from TENEX, under our commercial supply agreement with TENEX and deliveries under our long-term commercial supply agreement with Orano Cycle (“Orano”) or other suppliers; risks associated with our reliance on third-party suppliers and service providers to provide essential products and

2

services to us; risks related to the fact that we face significant competition from major producers who may be less cost sensitive or are wholly or partially government owned; risks that our ability to compete in foreign markets may be limited for various reasons; risks related to the fact that our revenue is largely dependent on our largest customers; risks related to our sales order book, including uncertainty concerning customer actions under current contracts and in future contracting due to market conditions and our lack of current production capability; risks related to whether or when government funding or demand for high-assay low-enriched uranium (“HALEU”) for government or commercial uses will materialize; risks and uncertainties regarding funding for continuation and deployment of the American Centrifuge technology; risks related to (i) our ability to perform and absorb costs under our agreement with the U.S. Department of Energy (“DOE”) to deploy a cascade of centrifuges to demonstrate production of HALEU for advanced reactors (the “HALEU Contract”), (ii) our ability to obtain contracts and funding to be able to continue operations and (iii) our ability to obtain and/or perform under other agreements; risks that (i) we may not obtain the full benefit of the HALEU Contract and may not be able or allowed to operate the HALEU enrichment facility to produce HALEU after the completion of the existing HALEU Contract or (ii) the HALEU enrichment facility may not be available to us as a future source of supply; risks related to uncertainty regarding our ability to commercially deploy competitive enrichment technology; risks related to the potential for further demobilization or termination of our American Centrifuge work; risks that we will not be able to timely complete the work that we are obligated to perform; risks related to our ability to perform fixed-price and cost-share contracts such as the HALEU Contract, including the risk that costs could be higher than expected; risks related to our significant long-term liabilities, including material unfunded defined benefit pension plan obligations and postretirement health and life benefit obligations; risks relating to our 8.25% notes (the “8.25% Notes”) maturing in February 2027; risks of revenue and operating results fluctuating significantly from quarter to quarter, and in some cases, year to year; risks related to the impact of financial market conditions on our business, liquidity, prospects, pension assets and insurance facilities; risks related to the Company’s capital concentration; risks related to the value of our intangible assets related to the sales order book and customer relationships; risks related to the limited trading markets in our securities; risks related to decisions made by our Class B stockholders regarding their investment in the Company based upon factors that are unrelated to the Company’s performance; risks that a small number of holders of our Class A Common Stock, par value $0.10 per share (“Class A Common Stock”) (whose interests may not be aligned with other holders of our Class A Common Stock), may exert significant influence over the direction of the Company; risks related to (i) the use of our net operating losses (“NOLs”) carryforwards and net unrealized built-in losses (“NUBILs”) to offset future taxable income and the use of the Rights Agreement (as defined herein) to prevent an “ownership change” as defined in Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”) and (ii) our ability to generate taxable income to utilize all or a portion of the NOLs prior to the expiration thereof and NUBILs; failures or security breaches of our information technology systems; risks related to our ability to attract and retain key personnel; risks related to the potential for the DOE to seek to terminate or exercise its remedies under its agreements with the Company; risks related to actions, including reviews, that may be taken by the United States government, the Russian government or other governments that could affect our ability to perform under our contractual obligations or the ability of our sources of supply to perform under their contractual obligations to us; risks related to our ability to perform and receive timely payment under agreements with the DOE or other government agencies, including risks and uncertainties related to the ongoing funding by the government and potential audits; risks related to changes or termination of agreements with the U.S. government or other counterparties; risks related to the competitive environment for our products and services; risks related to changes in the nuclear energy industry; risks related to the competitive bidding process associated with obtaining contracts, including government contracts; risks that we will be unable to obtain new business opportunities or achieve market acceptance of our products and services or that products or services provided by others will render our products or services obsolete or noncompetitive; risks related to potential strategic transactions that could be difficult to implement, disrupt our business or change our business profile significantly; risks related to the outcome of legal proceedings and other contingencies (including lawsuits and government investigations or audits); risks related to the impact of government regulation and policies including by the DOE and the U.S. Nuclear Regulatory Commission; risks of accidents during the transportation, handling or processing of hazardous or radioactive material that may pose a health risk to humans or animals, cause property or environmental damage, or result in precautionary evacuations; risks associated with claims and litigation arising from past activities at sites we currently operate or past activities at sites that we no longer operate, including the Paducah, Kentucky, and Portsmouth, Ohio, gaseous diffusion plants; and other risks and uncertainties discussed in this and our other filings with the Securities and Exchange Commission (“SEC”), including under Part I, Item 1A, Risk Factors, in our Annual Report on Form 10-K for the year ended December 31, 2021, and under Part II, Item 1A, Risk Factors of this Quarterly Report on Form 10-Q.

These factors may not constitute all factors that could cause actual results to differ from those discussed in any forward-looking statement. Accordingly, forward-looking statements should not be relied upon as a predictor of actual results. Readers are urged to carefully review and consider the various disclosures made in this report and in our other filings with the SEC that attempt to advise interested parties of the risks and factors that may affect our business. We do not undertake to update our forward-looking statements to reflect events or circumstances that may arise after the date of this Quarterly Report on Form 10-Q, except as required by law.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION

Basis of Presentation and Principles of Consolidation

The unaudited Consolidated Financial Statements of Centrus Energy Corp. (“Centrus” or the “Company”), which include the accounts of the Company, its principal subsidiary, United States Enrichment Corporation, and its other subsidiaries, as of September 30, 2022, and for the three and nine months ended September 30, 2022, and 2021, have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The unaudited Consolidated Balance Sheet as of December 31, 2021, was derived from audited Consolidated Financial Statements, but does not include all disclosures required by generally accepted accounting principles in the United States (“GAAP”). In the opinion of management, the unaudited Consolidated Financial Statements reflect all adjustments, including normal recurring adjustments, necessary for a fair statement of the financial results for the interim period. Certain prior year amounts have been reclassified for consistency with the current year presentation. Certain information and notes normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to such rules and regulations. All material intercompany transactions have been eliminated. The Company’s components of comprehensive income for the three and nine months ended September 30, 2022 and 2021, are insignificant.

Operating results for the three and nine months ended September 30, 2022, are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. The unaudited Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and related notes and Management's Discussion and Analysis of Financial Condition and Results of Operations included in the Annual Report on Form 10-K for the year ended December 31, 2021.

Significant Accounting Policies

The accounting policies of the Company are set forth in Note 1 to the Consolidated Financial Statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. There has not been a material change to the Company’s accounting policies since that report.

Accounts receivable	$	7.4	$	29.1
* Billings under certain contracts in the Technical Solutions segment are invoiced based on approved provisional billing rates. Unbilled revenue represents the difference between actual costs incurred and invoiced amounts. The Company expects to invoice and collect the unbilled amounts after actual rates are submitted to the customer and approved. Unbilled revenue also includes unconditional rights to payment that are not yet billable under applicable contracts pending the compilation of supporting documentation.

Contract Liabilities

The following table presents changes in contract liability balances (in millions):

	September 30, 2022		December 31,   2021		Year-To-Date Change
Accrued loss on HALEU Contract:
Current - Accounts payable and accrued liabilities	$	—	$	0.5	$	(0.5)
Deferred revenue - current	$	249.6	$	288.1	$	(38.5)
Advances from customers - current	$	15.3	$	15.0	$	0.3
Advances from customers - noncurrent	$	46.2	$	45.1	$	1.1

Previously deferred sales recognized in revenue totaled $59.7 million and $28.5 million in the nine months ended September 30, 2022 and 2021, respectively.

LEU Segment

The SWU component of low-enriched uranium (“LEU”) typically is bought and sold under contracts with deliveries over several years. The Company’s agreements for natural uranium sales generally are shorter-term, fixed-commitment contracts. The Company’s order book of sales under contract in the LEU segment (“order book”) extends to 2029. As of September 30, 2022, the order book was approximately $1.0 billion. The order book represents the estimated aggregate dollar amount of revenue for future SWU and uranium deliveries under contract and includes approximately $311.1 million of Deferred Revenue and Advances from Customers. As of December 31, 2021, the order book was also approximately $1.0 billion.

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

Technical Solutions Segment

Revenue for the Technical Solutions segment, representing the Company’s 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.

On October 31, 2019, the Company signed a cost-share contract with the U.S. Department of Energy (“DOE”) (the “HALEU Contract”) to deploy a cascade of centrifuges to demonstrate production of high-assay, low-enriched uranium (“HALEU”) for advanced reactors. HALEU is a component of an advanced nuclear reactor fuel that is not commercially available today and may be required for a number of advanced reactor and fuel designs currently under development in both the commercial and government sectors. The program has been under way since May 31, 2019, when the Company and DOE signed a preliminary letter agreement that allowed work to begin while the full contract was being finalized.

In 2019, under the HALEU Contract, DOE agreed to reimburse the Company for 80% of its costs incurred in performing the contract. The DOE has modified the contract several times to increase the total contract funding to $156.3 million as of September 30, 2022. Subsequent to September 30, 2022, an additional modification increased the total contract funding to $158.9 million. In April 2022, the DOE modified the HALEU Contract to extend the period of performance to November 30, 2022. Costs under the HALEU Contract include program costs, including direct labor and materials and associated indirect costs that are classified as Cost of Sales, and an allocation of corporate costs supporting the program that are classified as Selling, General and Administrative Expenses. The impact to Cost of Sales in the nine months ended September 30, 2022 and 2021, is $0.5 million and $6.5 million, respectively, for previously accrued contract losses attributable to work performed in the periods. As of September 30, 2022, a total of $19.6 million of previously accrued contract losses have been realized and the accrued contract loss balance included in Accounts Payable and Accrued Liabilities is $0. The Company has received aggregate cash payments under the HALEU Contract of $155.1 million through September 30, 2022.

As previously reported, the DOE experienced a COVID-19 related supply chain delay in obtaining the HALEU storage cylinders. As a result, the DOE elected to change the scope of the existing contract and move the operational portion of the demonstration to a new, competitively-awarded contract. The Company does not currently have a contractual obligation to perform work in excess of the funding provided by DOE. If the DOE does not commit to additional costs above the existing funding, the Company may incur material additional costs or losses in future periods that could have an adverse impact on its financial condition and liquidity.

On June 28, 2022, the DOE released a request for proposals (“RFP”) for the completion and operation of the demonstration cascade. The RFP provides for a 50/50 cost share contract for the initial phase to complete the cascade and produce 20 kg of HALEU. Once 20 kg of HALEU has been produced, the base contract will transition to a cost-plus-incentive-fee contract for production of 900 kg over the subsequent 1-year period. The RFP includes options held by the DOE to extend performance up to an additional nine years, comprised of three options of three-years each, also on a cost-plus-incentive-fee basis.

Revenue for the Technical Solutions segment in the three and nine months ended September 30, 2021, also includes $43.5 million related to the settlement of the Company’s claims for reimbursements for certain pension and postretirement benefits costs incurred in connection with a past cost-reimbursable contract with DOE unrelated to the HALEU Contract. Under the terms of the settlement agreement, DOE paid the Company $43.5 million, of which $33.8 million was contributed to the pension plan in September 2021 for its subsidiary United States Enrichment Corp. (“Enrichment Corp.”) and $9.7 million was deposited in October 2021 in a trust for payment of postretirement health benefits payable by Enrichment Corp. After receiving payment, at the Company’s request, the case was dismissed.

3. CASH, CASH EQUIVALENTS AND RESTRICTED CASH

The following table summarizes the Company’s cash, cash equivalents and restricted cash as presented on the Consolidated Balance Sheets to amounts on the Consolidated Statements of Cash Flows (in millions):

	September 30, 2022		December 31, 2021
Cash and cash equivalents	$	131.7	$	193.8
Deposits for financial assurance - current (a)	0.2		0.2
Deposits for financial assurance - noncurrent	21.1		2.8
Total cash, cash equivalents and restricted cash	$	153.0	$	196.8

(a) Deposits for financial assurance - current is included within Other Current Assets in the Consolidated Balance Sheets.

The following table provides additional detail regarding the Company’s deposits for financial assurance (in millions):

	September 30, 2022				December 31, 2021
	Current		Long-Term		Current		Long-Term
Collateral for Inventory Loans	$	—	$	18.6	$	—	$	—

Other	0.2		0.1		0.2		0.2
Total deposits for financial assurance	$	0.2	$	21.1	$	0.2	$	2.8

The Company has provided financial assurance to states in which it was previously self-insured for workers’ compensation in accordance with each state’s requirements in the form of a surety bond or deposit that is fully cash collateralized by Centrus. Each surety bond or deposit is subject to reduction and/or cancellation, as each state determines the likely reduction of workers’ compensation obligations pertaining to the period of self-insurance. In March and May 2022, the Company entered into two inventory loans which required a cash deposit into an escrow fund. See Note 4, Inventories.

4. INVENTORIES

Centrus holds uranium at licensed locations (e.g., fabricators) in the form of natural uranium and as the uranium component of LEU. Centrus also holds SWU as the SWU component of LEU at licensed locations to meet book transfer requests by customers and suppliers. Fabricators process LEU into fuel for use in nuclear reactors. Components of inventories are as follows (in millions):

	September 30, 2022						December 31, 2021
	Current Assets		Current Liabilities (a)		Inventories, Net		Current Assets		Current Liabilities (a)		Inventories, Net
Separative work units	$	12.0	$	—	$	12.0	$	8.8	$	—	$	8.8
Uranium	197.3		75.4		121.9		82.3		8.4		73.9
Total	$	209.3	$	75.4	$	133.9	$	91.1	$	8.4	$	82.7

(a)This includes inventories owed to suppliers for advances of uranium.

Inventories are valued at the lower of cost or net realizable value. There were no valuation adjustments in the three and nine months ended September 30, 2022 and 2021.

12

The Company may also borrow SWU or uranium from customers or suppliers, in which case the Company will record the SWU and/or uranium and the related liability for the borrowing using a projected and forecasted purchase price over the borrowing period. In March and May 2022, the Company borrowed SWU which was recorded to inventory at a value of $9.4 million and $8.5 million, respectively. The inventory value was calculated based on the anticipated sourcing of inventory for repayment at the date of acquisition. In June 2022, the Company performed a revaluation of the Long-term Inventory Loans reflecting an updated projection of the timing and sources of inventory to be used for repayment. This revaluation was recorded to Cost of Sales and resulted in an increase of $5.5 million to the related liability. In October 2022, the Company borrowed additional SWU which was collateralized by restricted cash of $11.2 million.

In 2018 through 2020, the Company borrowed SWU inventory valued at $20.7 million. The cumulative liability was revalued to $25.5 million in the third quarter of 2021 to reflect an updated projection of the timing and sources of inventory to be used for repayment. Cost of Sales for the three and nine months ended September 30, 2021, includes the related expense of $4.8 million.

5. INTANGIBLE ASSETS

Intangible assets originated from the Company’s reorganization and application of fresh start accounting as of the date the Company emerged from bankruptcy, September 30, 2014, and reflect the conditions at that time. The intangible asset related to the Company’s sales order book is amortized as the order book, existing at emergence, is reduced, principally as a result of deliveries to customers. The intangible asset related to customer relationships is amortized using the straight-line method over the estimated average useful life of 15 years. Amortization expense is presented below gross profit on the Consolidated Statements of Operations and Comprehensive Income. Intangible asset balances are as follows (in millions):

	September 30, 2022						December 31, 2021
	Gross Carrying Amount		Accumulated Amortization		Net Amount		Gross Carrying Amount		Accumulated Amortization		Net Amount
Sales order book	$	54.6	$	38.3	$	16.3	$	54.6	$	35.5	$	19.1
Customer relationships	68.9		36.7		32.2		68.9		33.3		35.6

	Maturity	Current		Long-Term		Current		Long-Term
8.25% Notes:	Feb. 2027
Principal		$	—	$	74.3	$	—	$	74.3
Interest		6.1		21.4		6.1		27.5
Total		$	6.1	$	95.7	$	6.1	$	101.8

Interest on the Company’s 8.25% notes (the “8.25% Notes”) maturing in February 2027 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 were issued in connection with a troubled debt restructuring, therefore, all future interest payment obligations on the 8.25% Notes are included in the carrying value of the 8.25% Notes. As a result, interest payments are reported as a reduction in the carrying value of the 8.25% Notes and not as interest expense. As of September 30, 2022 and December 31, 2021, $6.1 million of interest was recorded as current and classified as Current Debt in the Consolidated Balance Sheets. Additional terms and conditions of the 8.25% Notes are described in Note 8, Debt, of

13

the Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.

7. FAIR VALUE

Fair value is 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 of assets and liabilities, the following hierarchy is used in selecting inputs, with the highest priority given to Level 1, as these are the most transparent or reliable:

•Level 1 assets include investments with quoted prices in active markets that the Company has the ability to liquidate as of the reporting date.

•Level 2 assets include investments in U.S. government agency securities, corporate and municipal debt whose estimates are valued based on observable inputs, other than quoted prices.

•Level 3 assets include investments with unobservable inputs, such as third-party valuations, due to little or no market activity.

Financial Instruments Recorded at Fair Value (in millions):

	September 30, 2022								December 31, 2021
	Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3		Total
Assets:
Cash and cash equivalents	$	131.7	$	—	$	—	$	131.7	$	193.8	$	—	$	—	$	193.8

Liabilities:
Deferred compensation obligation (a)	$	2.3	$	—	$	—	$	2.3	$	3.2	$	—	$	—	$	3.2

(a)    The deferred compensation obligation represents the balance of deferred compensation plus net investment earnings. The deferred compensation plan is funded through a rabbi trust. Trust funds are invested in mutual funds for which unit prices are quoted in active markets and are classified within Level 1 of the valuation hierarchy.

There were no transfers between Level 1, 2 or 3 during the periods presented.

Other Financial Instruments

As of September 30, 2022, and December 31, 2021, the Consolidated Balance Sheets carrying amounts for Accounts Receivable, Accounts Payable and Accrued Liabilities (excluding the deferred compensation obligation described above), and Payables under Inventory Purchase Agreements approximate fair value because of their short-term nature.

The carrying value and estimated fair value of long-term debt were as follows (in millions):

	September 30, 2022					December 31, 2021
	Carrying Value			Estimated Fair Value (a)		Carrying Value			Estimated Fair Value (a)
8.25% Notes	$	101.8	(b)	$	70.0	$	107.9	(b)	$	74.3

(a) Based on recent trading prices and bid/ask quotes as of or near the balance sheet date, which are considered Level 2 inputs based on the frequency of trading.

(b)    The carrying value of the 8.25% Notes consists of the principal balance of $74.3 million and the sum of current and noncurrent interest payment obligations until maturity. Refer to Note 6, Debt.

The Company reports service costs for its defined benefit pension plans and its postretirement health and life benefit plans in Cost of Sales and Selling, General and Administrative Expenses. The remaining components of net periodic benefit (credits) costs are reported as Nonoperating Components of Net Periodic Benefit Income.

On September 7, 2021, the Company collected $43.5 million from DOE, of which $33.8 million was contributed to the pension plan in September 2021 for its subsidiary, Enrichment Corp., and $9.7 million was deposited in October 2021, in a trust for payment of postretirement health benefits payable by Enrichment Corp. Refer to Note 2, Revenue and Contracts with Customers.

9. NET INCOME (LOSS) PER SHARE

Basic net income (loss) per share is calculated by dividing income (loss) allocable to common stockholders by the weighted average number of shares of common stock outstanding during the period. In calculating diluted net income (loss) per share, the number of shares is increased by the weighted average number of potential shares related to stock compensation awards. No dilutive effect is recognized in a period in which a net loss has occurred.

On February 2, 2021, the Company completed the exchange of 3,873 shares of its outstanding Series B Senior Preferred Stock, par value $1.00 per share (“Preferred Stock”) for (i) 231,276 shares of Class A Common Stock and (ii) a warrant to purchase 250,000 shares of Class A Common Stock at an exercise price of $21.62 per share, for an aggregate valuation of approximately $7.5 million. Refer to Note 10, Stockholders’ Equity.

The aggregate valuation of approximately $7.5 million, less accrued but unpaid dividends attributable to the acquired and retired shares of Preferred Stock, was considered for purposes of Net Income per Share for the nine months ended September 30, 2021, to be a deemed dividend in the aggregate amount equal to the amount by which it exceeded the carrying value of the Preferred Stock on the Balance Sheet of $6.6 million.

15

The weighted average number of common and common equivalent shares used in the calculation of basic and diluted income (loss) per share are as follows:

	Three Months Ended   September 30,				Nine Months Ended   September 30,

10. STOCKHOLDERS’ EQUITY

Common Stock Issuance

Pursuant to a sales agreement with its agents, the Company sold, through its At-the-Market (ATM) offering at the market price, an aggregate of 1,238,637 shares of its Class A Common Stock in the nine months ended September 30, 2021, for a total of $28.7 million. After expenses and commissions paid to the agents, the Company’s proceeds totaled $27.6 million. Additionally, the Company recorded direct costs of $0.4 million related to the issuance. The shares of Class A Common Stock were issued pursuant to the Company’s shelf registration statement on Form S-3 (File No. 333-239242), which became effective on August 5, 2020, and a supplement dated December 31, 2020, to the prospectus. The Company has used and/or intends to use the net proceeds from this offering for general working capital purposes, to invest in technology development and deployment and to repay outstanding debt.

Voting and Exchange Agreement

On February 2, 2021, the Company entered into an amendment (the “Voting Agreement Amendment”) to its existing Voting and Nomination Agreement with Mr. Morris Bawabeh, Kulayba LLC and M&D Bawabeh Foundation, Inc. (collectively, the “MB Group”) and an Exchange Agreement (as described below) whereby the MB Group agreed to support management’s recommendation on certain matters at the Company’s 2021 annual meeting of stockholders (the “Annual Meeting”) and Kulayba LLC agreed to exchange shares of the Company’s Preferred Stock for shares of the Company’s Class A Common Stock and a warrant to acquire additional shares of Class A Common Stock.

The Company and Kulayba LLC also entered into an Exchange Agreement, dated February 2, 2021 (the “Exchange Agreement”), pursuant to which Kulayba LLC agreed to exchange (the “Exchange”) 3,873 shares of

16

Preferred Stock, 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 of the Exchange Agreement and (ii) a Centrus Energy Corp. Warrant to Purchase Class A Common Stock (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 of the Exchange Agreement, subject to certain customary adjustments pursuant to the terms of the Warrant. The Warrant is exercisable by Kulayba LLC, unless terminated as provided in the Warrant, or the first to occur: (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 stockholders 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 October 17, 2022, the Company and Kulayba LLC amended the Warrant to permit the cashless exercise of the Warrant, whereby shares valued at the closing price on the day of the exercise would be withheld to pay the exercise price.

Awards under Executive Incentive Plan

Notional stock units are a component of the 2019 Executive Incentive Plan for participating executives for the three-year period ending December 31, 2021. The plan payouts were settled in Class A Common Stock in April 2021 and March 2022. In April 2020, notional stock units and stock appreciation rights were granted to participating executives with a vesting period ending in April 2023.

Prior to 2022, these awards were determined to be likely settled in cash, and thus compensation cost for the notional stock units and stock appreciation rights were re-measured each reporting period based on the trading price of the Company’s Class A Common Stock and the cumulative vested costs were accrued in Accounts Payable and Accrued Liabilities or Other Long-Term Liabilities.

A portion of the April 2021 interim payment related to the 2019 grants referenced above was paid in shares of the Company’s Class A Common Stock at the discretion of the Board of Directors. The related obligation of $7.5 million was reclassified from Accounts Payable and Accrued Liabilities to Excess of Capital over Par Value in the first quarter of 2021 based on the market share price at the time of the Board of Directors’ decision. In the second quarter of 2021, the Company withheld $2.4 million of shares to fund the grantees’ tax withholding obligations relating to the April 2021 interim payment.

In September 2021, notional stock units and stock appreciation rights were granted to participating executives with a vesting period ending in April 2024. The September 2021 awards are payable in shares of the Company’s Class A Common Stock and the grant-date value is included in Excess of Capital Over Par Value as the value is amortized over the vesting period.

In February 2022, the Compensation, Nominating and Governance Committee of the Board of Directors determined that remaining notional stock units granted in 2019 and 2020 would be paid in shares of the Company’s Class A Common Stock. The related obligation of $10.6 million was reclassified from Accounts Payable and Accrued Liabilities to Excess of Capital over Par Value in the first quarter of 2022 based on the market share price at the time of the Board’s decision. In the first quarter of 2022, the Company withheld $1.9 million of shares that vested during the period for the purpose of funding the grantees’ tax withholding obligations under the terms of the stock-based compensation plan.

In March 2022, restricted stock was granted to participating executives with a vesting period ending in March 2025. The March 2022 awards are payable in shares of the Company’s Class A Common Stock and the grant-date value is included in Excess of Capital Over Par Value as the value is amortized over the vesting period.

11. COMMITMENTS AND CONTINGENCIES

Commitments under SWU Purchase Agreements

TENEX

The Russian government-owned entity TENEX, Joint-Stock Company (“TENEX”), is a major supplier of SWU to the Company. Under a 2011 agreement with TENEX, as amended, (the “TENEX Supply Contract”), the Company purchases SWU contained in LEU received from TENEX, and the Company delivers natural uranium to TENEX for the LEU’s uranium component. The LEU that the Company obtains from TENEX is subject to quotas and other restrictions applicable to commercial Russian LEU. Further, the ability of the Company or TENEX to perform under the TENEX Supply Contract is vulnerable to (i) sanctions or restrictions that might be imposed by Russia, the United States, or other countries, as a result of the war in Ukraine, or otherwise, (ii) customers and other parties who may object to receiving or handling Russian LEU or SWU, or (iii) suppliers and service providers seeking to limit their involvement with business related to Russia.

The TENEX Supply Contract originally was signed with commitments through 2022, but was modified in 2015 to give the Company the right to reschedule certain quantities of SWU of the original commitments into the period 2023 and beyond, in return for the purchase of additional SWU in those years. The Company has exercised this right to reschedule in each year through December 31, 2022. As a result of exercising this right to reschedule, the Company will have purchase commitments that could extend through 2028.

The TENEX Supply Contract provides that the Company must pay for all SWU in its minimum purchase obligation each year, even if it fails to submit orders for such SWU. In such a case, the Company would pay for the SWU, but have to take the unordered SWU in the following year.

Pricing terms for SWU under the TENEX Supply Contract are based on a combination of market-related price points and other factors. This formula was subject to an adjustment at the end of 2018 that reduced the unit costs of SWU under this contract in 2019 and for the duration of the contract.

Orano

In 2018, the Company entered into an agreement (the “Orano Supply Agreement”) with the French company Orano Cycle for the long-term supply to the Company of SWU contained in LEU. The Orano Supply Agreement subsequently was assigned by Orano Cycle to its affiliate, Orano CE (“Orano”). Under the amended Orano Supply Agreement, the supply of SWU runs through 2030. The Orano Supply Agreement provides significant flexibility to adjust purchase volumes, subject to annual minimums and maximums in fixed amounts that vary year by year. The pricing for the SWU purchased by the Company is determined by a formula that uses a combination of market-related price points and other factors and is subject to certain floors and ceilings. 

Russian Suspension Agreement

Beginning in September 2022, the Russian Suspension Agreement is subject to two “sunset” reviews being conducted by the U.S. Department of Commerce (“DOC”) and the U.S. International Trade Commission (“ITC”), respectively, that will determine if the Russian Suspension Agreement should be maintained. These “sunset” reviews are required to be conducted every five years. This is the fifth round of “sunset reviews” of the Russian Suspension Agreement. The last round of reviews in 2016-17 concluded that termination of the Russian Suspension Agreement would lead to the continuation or recurrence of dumping of French LEU (a determination made by the DOC), and to the continuation or recurrence of material injury to the U.S. uranium industry (a determination made by the ITC), which resulted in the Russian Suspension Agreement being maintained. Even if the Russian Suspension Agreement were terminated as a result of the “sunset” reviews, the quotas under the 2020 legislation would remain in place.

Milestones Under the 2002 DOE-USEC Agreement

The Company’s predecessor USEC Inc. and DOE signed an agreement dated June 17, 2002, as amended (the “2002 DOE-USEC Agreement”), pursuant to which the parties made long-term commitments directed at resolving issues related to the stability and security of the domestic uranium enrichment industry. The 2002 DOE-USEC Agreement requires Centrus to develop, demonstrate and deploy advanced enrichment technology in accordance with milestones, including the deployment of a commercial American Centrifuge Plant, and provides for remedies in the event of a failure to meet a milestone under certain circumstances, including terminating the 2002 DOE-USEC Agreement, revoking Centrus’ access to DOE’s centrifuge technology that is required for the success of the Company’s ongoing work with the American Centrifuge technology, requiring Centrus to transfer certain rights in the American Centrifuge technology and facilities to DOE, and requiring Centrus to reimburse DOE for certain costs associated with the American Centrifuge technology. The 2002 DOE-USEC Agreement provides that if a delaying event beyond the control and without the fault or negligence of Centrus occurs that could affect Centrus’ ability to meet the American Centrifuge Plant milestone under the 2002 DOE-USEC Agreement, DOE and the Company will jointly meet to discuss in good faith possible adjustments to the milestones as appropriate to accommodate the delaying event. In 2014, the 2002 DOE-USEC Agreement and other agreements between the Company and DOE were assumed by Centrus subject to an express reservation of all rights, remedies and defenses by DOE and the Company under those agreements. DOE and the Company have agreed that all rights, remedies and defenses of the parties with respect to any missed milestones and all other matters under the 2002 DOE-USEC Agreement continue to be preserved, and that the time limits for each party to respond to any missed milestones continue to be tolled.

Legal Matters

From time to time, the Company is involved in various pending legal proceedings, including the pending legal proceedings described below.

In 1993, the United States Enrichment Corporation, at that time a wholly owned government corporation (“USEC-Government”), entered into a lease for the Paducah and Portsmouth Gaseous Diffusion Plants (collectively, the “GDPs”) with the DOE. As part of that lease, DOE and USEC-Government also entered into a memorandum of understanding (“Power MOU”) regarding power purchase agreements between DOE and the providers of power to the GDPs. Under the Power MOU, DOE and USEC-Government agreed upon the allocation of rights and liabilities under the power purchase agreements. In 1998, USEC-Government was privatized and became the United States Enrichment Corporation, now a principal subsidiary of the Company (“Enrichment Corp.”). Pursuant to legislation authorizing the privatization, the lease for the GDPs, which included the Power MOU as an Appendix, was transferred to Enrichment Corp., and Enrichment Corp. was given the right to purchase power from DOE. The Paducah Gaseous Diffusion Plant (“Paducah GDP”) was shut down in 2013 and deleased by Enrichment Corp. in 2014. On August 4, 2021, DOE informally informed Enrichment Corp. that the Joppa power plant, which had supplied power to the Paducah GDP, was planned to be decontaminated and decommissioned (“D&D”). According to DOE, the power purchase agreement with Electric Energy Inc. (“EEI”) requires DOE to pay for a portion of the D&D costs of the Joppa power plant and DOE has asserted that a portion of the DOE liability is the responsibility of Enrichment Corp. under the Power MOU in the amount of approximately $9.6 million. The Company is assessing DOE’s assertions including whether all or a portion of any such potential liability had been previously settled. The Company has not formed an opinion on the merits nor is it able to estimate the potential liability, if any, and no expense or liability has been accrued.

On May 26, 2019, the Company, Enrichment Corp., and six other DOE contractors who have operated facilities at the Portsmouth Gaseous Diffusion Plant in Piketon, Ohio ( “Portsmouth GDP”) (including, in the case of the Company, the American Centrifuge Plant site located on the premises) were named as defendants in a class action complaint filed by Ursula McGlone, Jason McGlone, Julia Dunham, and K.D. and C.D., minor children by and through their parent and natural guardian Julia Dunham (collectively, the “McGlone Plaintiffs”) in the U.S. District Court in the Southern District of Ohio, Eastern Division. The complaint seeks damages for alleged off-site contamination allegedly resulting from activities on the Portsmouth GDP site. The McGlone Plaintiffs are seeking

19

to represent a class of (i) all current or former residents within a seven-mile radius of the Portsmouth GDP site and (ii) all students and their parents at the Zahn’s Corner Middle School from 1993-present. The complaint was amended on December 10, 2019 and on January 10, 2020 to add additional plaintiffs and new claims. On July 31, 2020, the court granted in part and denied in part the defendants’ motion to dismiss the case. The court dismissed ten of the fifteen claims and allowed the remaining claims to proceed to the next stage of the litigation process. On August 18, 2020, the McGlone Plaintiffs filed a motion for leave to file a third amended complaint and notice of dismissal of three of the individual plaintiffs. On March 18, 2021, the McGlone Plaintiffs filed a motion for leave to file a fourth amended complaint to add new plaintiffs and allegations. On March 19, 2021, the court granted the McGlone Plaintiffs’ motion for leave to amend the complaint to include Price-Anderson Nuclear Industries Indemnity Act (“Price-Anderson Act”) and eight other state law claims. On May 24, 2021, the Company, Enrichment Corp., and the other defendants filed their motion to dismiss the complaint. On March 31, 2022, the court granted our motion in part by dismissing claims brought on behalf of the minor children but allowed the other claims to proceed. As such, the discovery stage of litigation is continuing. On April 28, 2022, the Company, Enrichment Corp., and the other defendants filed their answer to the fourth amended complaint. The Company believes that its operations at the Portsmouth GDP site were fully in compliance with the Nuclear Regulatory Commission’s regulations. Further, the Company and Enrichment Corp. believe that any such liability should be indemnified under the Price-Anderson Act. The Company and Enrichment Corp. have provided notifications to DOE required to invoke indemnification under the Price-Anderson Act and other contractual provisions.

On June 8, 2022, the Company, Enrichment Corp., and six other DOE contractors who operated facilities at the Portsmouth GDP were named as defendants in a complaint filed by Brad Allen Lykins, as administrator of the estate of Braden Aaron Lee Lykins in the U.S. District Court in the Southern District of Ohio, Eastern Division (“Lykins Complaint”). In March 2021, Brayden Lykins, who was thirteen years old, passed away from leukemia. The complaint alleges that the defendants released radiation into the environment in violation of the Price-Anderson Act causing Lykins’ death and seeks monetary damages. On August 30, 2022, the Company and Enrichment Corp. and the other defendants filed their answer to the Lykins Compliant. The Company and Enrichment Corp. believe that their operations at the Portsmouth GDP site were fully in compliance with the Nuclear Regulatory Commission’s regulations. Further, the Company and Enrichment Corp. believe that any such liability should be indemnified under the Price-Anderson Act. The Company and Enrichment Corp. have provided notifications to DOE required to invoke indemnification under the Price-Anderson Act and other contractual provisions.

Centrus is subject to various legal proceedings and claims, either asserted or unasserted, which arise in the ordinary course of business. While the outcome of these claims cannot be predicted with certainty, other than the above, Centrus does not believe that the outcome of any of these legal matters, individually and in the aggregate, will have a material adverse effect on its cash flows, results of operations, or consolidated financial condition.

Item 2. 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 unaudited 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 COVID-19 pandemic, including emerging variants, and the war in Ukraine. See “Forward-Looking Statements” at the beginning of this Quarterly Report on Form 10-Q.

Overview

Centrus Energy Corp., a Delaware corporation (“Centrus,” 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.

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

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

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

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

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 continue to increase substantially, reaching $95 per SWU by September 30, 2022. This represents an increase of 70% since the beginning of the year and 179% 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.

22

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/or export controls against certain Russian organizations and/or individuals. While sanctions imposed to date do not preclude imports of Russian uranium enrichment, it is possible that additional restrictions could arise in the future that would affect our ability to purchase and re-sell Russian uranium enrichment, which could have a negative material impact on our business. Further, sanctions could be imposed that may impact our ability to transport, import, take delivery or make payments related to the uranium enrichment we purchase.

Even if sanctions or other restrictions are not imposed, the current events in Ukraine could impact our ability to make future sales. For example, customers may be unwilling to accept material we purchase from TENEX. Further, since a portion of the price paid under the supply contract is based on commodity indices, the recent increases in market prices, as a result of the war in Ukraine, will have a corresponding impact on our cost of sales.

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. 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. To address these changes, we will continue to evaluate opportunities to grow our business organically or through acquisitions and other strategic transactions.

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

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

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

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

23

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

Under a three-year cost-share contract with DOE that began in 2019 (the “HALEU Contract”), Centrus has been constructing a cascade of sixteen AC100M centrifuges in Piketon, Ohio to demonstrate HALEU production. The Company’s goal is to complete the demonstration and scale up production of HALEU and LEU, meeting the needs of new and existing reactors as well as national security and other U.S. government requirements for enriched uranium.

The demonstration contract was originally set to expire on June 1, 2022. However, the DOE experienced a COVID-19 related supply chain delay in obtaining the HALEU storage cylinders it was required to provide under the contract. Since it is not possible to begin HALEU production without the storage cylinders, it was not possible to complete the operational portion of the HALEU demonstration under the existing HALEU Contract. The HALEU Contract has been extended to November 30, 2022. Also, the DOE elected to change the scope of the HALEU Contract and move the operational portion of the demonstration to a new, competitively-awarded contract that would provide for operations beyond the term of the existing HALEU Contract.

On June 28, 2022, the DOE released a request for proposals (“RFP”) for the completion and operation of the demonstration cascade. The RFP provides for a 50/50 cost share contract for the initial phase of the base contract to complete the cascade and begin operations. The second phase includes continued operations and maintenance on a cost-plus-incentive-fee basis. Finally, the RFP includes options to 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 award of a contract and the exercise of any options is subject to appropriation. If a contract is awarded to the Company under the terms proposed by DOE in the RFP, the cost share in Phase 1 could have a material impact on the Company’s liquidity during the initial phase of the base contract, although the degree of impact cannot be estimated at this time. DOE has incrementally increased funds on the existing HALEU contract with total funding to date of $158.9 million.

Additional COVID-19-related impacts, or additional changes to the existing scope of the HALEU Contract could result in further material increases to our estimate of the costs required to complete the existing HALEU Contract, as well as delay completion of the contract. The Company currently does not have a contractual obligation to perform work in excess of the funding provided by DOE and, therefore, no additional loss has been accrued as of September 30, 2022. If the DOE does not commit to additional costs, above the existing funding, we may incur costs or losses in future periods that, if material, could have an adverse impact on our financial condition and liquidity.

The Inflation Reduction Act signed into law on August 16, 2022, includes a $700 million appropriation for the DOE HALEU Availability Program, with the goal of making HALEU commercially available by 2026 of which $500 million will be available to support new production and $200 million for resolving related supply chain challenges such as HALEU transportation. On October 6, 2022, the Department of Energy issued a “Sources Sought” notice outlining a potential 10-year program to support the construction and operation of HALEU enrichment in the United States via government purchases of up to 25 metric tons of HALEU per year. The Sources Sought notice is a preliminary step, not a formal request for proposals, and the Department would require additional annual appropriations beyond what is contained in the Inflation Reduction Act to fully implement that program. On October 14, 2022, the Company attended an Industry Day, where the DOE provided additional information on the potential procurement activity. The Company is evaluating its next steps associated with participating in a potential future request for proposal.

24

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.

We believe our investments in our enrichment technology and the HALEU demonstration 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. At present, there are a number of advanced reactors under development that would use HALEU fuel. For example, of the ten advanced reactor designs selected by the DOE for its Advanced Reactor Demonstration Program, nine will require HALEU. In addition, the first non-light water reactor to have begun active NRC-license review requires HALEU. The U.S. Department of Defense recently awarded a contract to construct a prototype HALEU-fueled mobile microreactor in the next three to four years as part of a program called “Project Pele.” The U.S. Air Force also announced plans to deploy a microreactor at Eielson Air Force Base in Alaska. While the use of HALEU is not an express requirement of the Air Force program, the vast majority of microreactor designs are expected to need HALEU. In addition, the Defense Advanced Research Projects Agency (“DARPA”) is funding an effort called Demonstration Rocket for Agile Cislunar Operations (“DRACO”), which aims to demonstrate a HALEU-fueled nuclear thermal propulsion system that could eventually support missions to the moon and Mars.

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

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.

COVID-19 Update

During the height of the COVID-19 pandemic, the Company implemented measures to protect its workforce and to maintain critical operations. Over the course of the HALEU Contract, our Technical Solutions segment was impacted by supply chain disruptions and increased costs as a result of the pandemic. We also experienced delays by our suppliers and increased costs from them as a result of the impact of COVID-19. Since then, government requirements and public health guidelines including Center for Disease Control (CDC) guidance, as well as business and industry best practices regarding COVID-19 and COVID-19 vaccines, changed as the public vaccination rates increased, new information became available, and further research was conducted. As a result, we have adjusted our measures accordingly. However, we continue to follow CDC guidance and monitor any new development relating to COVID-19 transmission rates to ensure we take appropriate actions to maintain the health and safety of our employees and our operations.

For further discussion, refer to Part I, Item 1A, Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2021, as updated by Part II, Item 1A, Risk Factors, in this Quarterly Report on Form 10-Q.

Market Conditions and Outlook

The global nuclear industry outlook has begun to improve after many years of decline or 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 World Nuclear Association, as of September 2022, there were 60 reactors under construction worldwide, about a third of which are in China. The United States, with 92 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 lower cost natural gas resources, until recently as gas prices have been rising, and the expansion of subsidized renewable energy. 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, there are active efforts to develop, demonstrate, and deploy next generation reactors in the United States, many of which are expected to require HALEU.

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. While ten reactors in Japan have restarted, an additional seven are expected to restart in 2023, with more reactors expected to follow in subsequent years. Due to the war in Ukraine, the European Union 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 U.S. Department of Commerce reached an agreement with the Russian Federation on an extension of the 1992 Russian Suspension Agreement, a trade agreement that allows for Russian-origin nuclear fuel to be exported to the United States in limited quantities. The two parties agreed to extend the agreement through 2040 and to set aside a significant portion of the quota for Centrus’ shipments to the United States through 2028 to perform under our long-term supply (purchase) agreement (the “TENEX Supply Contract”) with the Russian government entity, TENEX, Joint-Stock Company (“TENEX”). This outcome allowed for sufficient quota for Centrus to continue serving its utility customers.

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 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

26

added in the future that would affect our ability to purchase and re-sell Russian uranium enrichment, 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.

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 but none of these have been adopted as of the date of this filing.

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. Accordingly, 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.

Operating Results

Our revenues, operating results, and cash flows can fluctuate significantly from quarter to quarter and year to year. Our sales 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 2022-2027. Operating results for the three and nine months ended September 30, 2022, are not necessarily indicative of the results that may be expected for the year ending December 31, 2022.

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 2022. Please see Forward Looking Statements at the beginning of this Quarterly Report on Form 10-Q.

Our order book of sales under contract in the LEU segment extends to 2029. As of September 30, 2022 and December 31, 2021, 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 September 30, 2022, 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 Russian Suspension Agreement, 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 purchases of SWU or uranium or goods or services required for the purchase or delivery of such SWU or uranium;

•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 components;

27

•Costs, 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;

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

•The length and severity of the COVID-19 pandemic and its impact on our operations.

For further discussion of these uncertainties, refer to Part I, Item 1A, Risk Factors, in our Annual Report on Form 10-K for the year ended December 31, 2021, as updated by Part II, Item 1A, Risk Factors, in this Quarterly Report on Form 10-Q.

Revenue

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

Revenue from our LEU segment is derived primarily from the following: 

•sales of the SWU component of LEU,

•sales of natural uranium, and

•sales of enriched uranium product that include both the natural uranium 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 Contract and a variety of other contracts with public and private sector customers.

SWU and Uranium Sales

Revenue from our LEU segment accounted for approximately 61% and 74% of our total revenue for the three and nine months ended September 30, 2022, respectively. The majority of our customers are domestic and international utilities that operate nuclear power plants, with international sales constituting approximately 50% of revenue from our LEU segment since 2020. Our agreements with electric utilities are primarily medium and long-term fixed-commitment contracts under which our customers are obligated to purchase a specified quantity of the SWU component of LEU from us. Contracts where we sell both the SWU and natural uranium component of LEU to utilities or where we sell natural uranium to utilities and other nuclear fuel related companies are generally shorter-term, fixed-commitment contracts.

Revenue is recognized at the time LEU or uranium is delivered under the terms of our contracts. The timing of customer deliveries is affected by, among other things, electricity markets, reactor operations, maintenance and refueling outages, and customer inventories. Based on customers’ individual needs, some customers are building inventories and may choose to take deliveries under annual purchase obligations later in the year or in subsequent years. Customer payments for the SWU component of LEU averaged approximately $7.6 million per order in the nine months ended September 30, 2022. As a result, a relatively small change in the timing of customer orders for LEU may cause significant variability in our operating results year over year.

28

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 for further details.

Our financial performance over time can be affected significantly by changes in prices for SWU and natural uranium. Market prices for SWU and uranium 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 prices sharply higher. Since our sales 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 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 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 46% of the world’s capacity, and Russian capacity significantly exceeds its domestic needs. According to data from the World Nuclear Association, 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 on line.

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. On occasion, we will accept payment in euros for spot sales that may be subject to short-term 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, nominally commencing 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. 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 at contract inception, or as the quantity of natural uranium is finalized, if variable.

Cost of sales for SWU and natural uranium is based on the amount of SWU and natural uranium 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.

Technical Solutions

Our Technical Solutions segment reflects our technical, manufacturing, engineering, and operations services offered to public and private sector customers, including the American Centrifuge engineering, procurement, construction, manufacturing, and operations services being performed under the HALEU Contract. With our government and private sector customers, we seek to leverage our domestic enrichment technology and experience, engineering know-how, and precision manufacturing facility to assist customers with a range of engineering, design, and advanced manufacturing projects, including the production of fuel for next-generation nuclear reactors and the development of related facilities. We continue to invest in advanced technology because of the potential for future growth into new areas of business for the Company, while also preserving our unique workforce at our Technology and Manufacturing Center in Oak Ridge, Tennessee, and our production facility near Piketon, Ohio.

Government Contracting

On October 31, 2019, we signed the three-year cost-share HALEU Contract with DOE to deploy a cascade of centrifuges to demonstrate production of HALEU for advanced reactors. The three-year program has been under way since May 31, 2019, when the Company and DOE signed an interim HALEU letter agreement that allowed work to begin while the full contract was being finalized. The Company entered into this cost-share contract with DOE as a critical first step on the road back to the commercial production of enriched uranium, which the Company had terminated in 2013 with the closure of the Paducah GDP. Centrus is competing for a follow-on contract to complete construction, make the cascade operational, and then operate the cascade and produce HALEU. Centrus is the only company with an NRC license to enrich HALEU.

Commercial Contracting

Since March of 2018, Centrus has provided design, technical, and resource support for X-energy related to its Tri-Structural Isotropic (“TRISO”) fuel manufacturing process. Currently, work is being performed under a services agreement with X-energy signed in August 2021 to provide services for detailed design of the TRISO fuel fabrication facility and various support services for establishing their TRISO Research and Development Center. X-energy is funded under the current DOE cooperative agreement titled Advanced Reactor Demonstration Program (“ARDP”). At our discretion, the task orders under the new agreement may include in-kind contributions that we are not currently providing, but, may provide in the future. The existing contractual scope of work expires on December 31, 2022, and may or may not be extended at the discretion of the X-energy.

Prior Site Services Work

We formerly performed sites services work under contracts with DOE and its contractors at the former Portsmouth GDP. In September 2021, the Company and DOE fully settled the Company’s claims for reimbursement of certain pension and postretirement benefit costs incurred in connection with a past cost-reimbursable contract for work performed at the Portsmouth GDP. Under the terms of the settlement agreement, DOE paid the Company $43.5 million in September 2021, of which $33.8 million was contributed in September 2021 to the pension plan for its subsidiary United States Enrichment Corp. (“Enrichment Corp.”) and $9.7 million was deposited in October 2021 in a trust for payment of postretirement health benefits payable by Enrichment Corp. The payment of $43.5 million is included in revenue of the Technical Solutions segment for the three and nine months ended September 30, 2021.

Revenue

Revenue from the LEU segment was $20.2 million and $32.0 million in the three months ended September 30, 2022 and 2021, respectively, a decrease of $11.8 million (or 37%). The decrease is due to a 76% decrease in the average price of SWU sold, partially offset by a 60% increase in the volume of SWU sold, for the three months ended September 30, 2022, largely due to the variability in timing of utility customer orders and related contracts.

Revenue from uranium sales was $12.5 million and 12.9 million in the three months ended September 30, 2022 and 2021, respectively.

Revenue from the Technical Solutions segment was $13.0 million and $59.3 million in the three months ended September 30, 2022 and 2021, respectively, a decrease of $46.3 million (or 78%). Revenue in the third quarter of 2021 included $43.5 million related to the settlement of the Company’s claims for reimbursements for certain pension and postretirement benefits costs incurred in connection with a past cost-reimbursable contract performed at the Portsmouth GDP. Excluding this settlement, the decrease in revenue in the three months ended September 30, 2022, was primarily related to a $1.2 million decrease in revenue generated by the HALEU Contract and a $0.8 million decrease in revenue generated by the X-Energy contract, as well as a $0.8 million decrease across other contracts.

32

Cost of Sales

Cost of sales for the LEU segment was $18.9 million and $23.7 million in the three months ended September 30, 2022 and 2021, respectively, a decrease of $4.8 million (or 20%). The decrease is primarily a result of a $4.8 million charge to cost of sales for the three months ended September 30, 2021 for the revaluation of obligations for SWU borrowed.

Cost of sales for the Technical Solutions segment was $12.0 million and $18.1 million in the three months ended September 30, 2022 and 2021, respectively, a decrease of $6.1 million (or 34%). The decrease of $6.1 million in the three months ended September 30, 2022, is related to a reduction in costs of approximately $4.5 million associated with the HALEU Contract, $0.9 million associated with the X-energy contract, and $0.7 million associated with other contracts. For details on HALEU Contract accounting, refer to “Technical Solutions - Government Contracting” above.

Gross Profit

Gross profit for the LEU segment was $1.3 million and $8.3 million in the three months ended September 30, 2022 and 2021, respectively, a decrease of $7.0 million (or 84%). The $7.0 million decrease in gross profit in the three months ended September 30, 2022, was due primarily to a decrease in the average profit margin per SWU, which was partially offset by an increase in SWU sales volume.

Gross profit for the Technical Solutions segment was $1.0 million and $41.2 million in the three months ended September 30, 2022 and 2021, respectively, a decrease of $40.2 million (or 98%). Gross profit in the three months ended September 30, 2021, included $43.5 million of revenue related to the settlement of the Company’s claim for costs incurred in connection with a prior cost-reimbursable contract with DOE. Excluding the settlement with DOE, gross profit increased $3.3 million in the three-month period mainly due to a $3.2 million increase in the gross profit generated from the HALEU Contract. The increase related to the HALEU Contract is primarily attributable to the Company’s costs under the HALEU Contract being fully recoverable in the current year, as the Company had contributed its contractually required cost share prior to December 31, 2021.

Revenue

Revenue from the LEU segment was $123.4 million and $115.3 million in the nine months ended September 30, 2022 and 2021, respectively, an increase of $8.1 million (or 7%). The increase is due to a 19% increase in the average price of SWU, partially offset by a 13% decrease in the volume of SWU sold in the nine months ended September 30, 2022, largely due to the variability in timing of utility customer orders and the contracts under which SWU were sold during the periods.

Revenue from uranium sales was $17.4 million and $12.9 million in the nine months ended September 30, 2022 and 2021, respectively. For the nine-month period, the average price increased 30%, partially offset by a decrease in sales volume of 16%.

Revenue from the Technical Solutions segment was $44.2 million and $94.0 million in the nine months ended September 30, 2022 and 2021, respectively, a decrease of $49.8 million (or 53%). Revenue in the third quarter of 2021 included $43.5 million related to the settlement of the Company’s claims for reimbursements for certain pension and postretirement benefits costs incurred in connection with a past cost-reimbursable contract performed at the Portsmouth GDP. Excluding the settlement with DOE, the $6.3 million decrease in revenue in the nine months ended September 30, 2022, was primarily related to a $7.8 million decrease in revenue from the HALEU Contract and a $2.6 million decrease in revenue from X-energy, partially offset by a $4.1 million increase in revenue generated from other contracts.

34

Cost of Sales

Cost of sales for the LEU segment was $59.8 million and $76.1 million in the nine months ended September 30, 2022 and 2021, respectively, a decrease of $16.3 million (or 21%). The decrease largely reflects decreases in the volume of SWU sold and in the average SWU unit cost. The volume of SWU sold decreased 13% for the nine months ended September 30, 2022 and the average SWU unit cost decreased 21%. Cost of sales for the nine months ended September 30, 2022 and 2021, included $5.5 million and $4.8 million, respectively, for the revaluation of obligations for SWU borrowed in 2018-2022.

Cost of sales for the Technical Solutions segment was $38.3 million and $54.9 million in the nine months ended September 30, 2022 and 2021, respectively, a decrease of $16.6 million (or 30%). The decrease of $16.6 million in the nine months ended September 30, 2022, is related to a reduction in costs of approximately $18.1 million associated with the HALEU Contract and a reduction in costs of approximately $3.0 million associated with the X-energy contract, partially offset by a $4.5 million increase in costs related to costs incurred by new contract work. For details on HALEU Contract accounting, refer to “Technical Solutions - Government Contracting” above.

Gross Profit

Gross profit for the LEU segment was $63.6 million and $39.2 million in the nine months ended September 30, 2022 and 2021, respectively, an increase of $24.4 million (or 62%). The increase in gross profit was due primarily to an increase in the average profit margin per SWU, which was partially offset by a decrease in SWU sales volume.

Gross profit for the Technical Solutions segment was $5.9 million and $39.1 million in the nine months ended September 30, 2022 and 2021, respectively, a decrease of $33.2 million (or 85%). Gross profit in the nine months ended September 30, 2021 included $43.5 million of revenue related to the settlement of the Company’s claim for costs incurred in connection with a prior cost-reimbursable contract with DOE. Excluding the settlement with DOE, gross profit from the Technical Solutions segment increased $10.3 million over the nine months ended September 30, 2021. This increase in gross profit in the nine months ended September 30, 2022 is related to a $10.2 million increase in the gross profit generated from the HALEU Contract which included a $1.6 million rent credit for the Piketon Facility, and a $0.4 million increase in gross profit generated from the X-energy contract. The remaining $0.3 million net decrease in the gross margin is attributable to the Company’s other contracts. The increase related to the HALEU Contract is primarily attributable to the Company’s costs under the HALEU Contract being fully recoverable in the current year as the Company had contributed its contractually required cost share prior to December 31, 2021.

Advanced Technology Costs

Advanced technology costs were $5.4 million and $0.6 million in the three months ended September 30, 2022 and 2021, respectively, an increase of $4.8 million (or 800%). Advanced technology costs consist of American Centrifuge work and related expenses that are outside of our customer contracts in the Technical Solutions segment, including bid and proposal activities and work to improve our centrifuge technology.

Amortization of Intangible Assets

Amortization of intangible assets was $1.1 million and $1.7 million in the three months ended September 30, 2022 and 2021, respectively, an increase of $0.6 million (or 35%). Amortization expense for the intangible asset related to the September 2014 sales order book is a function of SWU sales volume under that order book, and amortization expense for the intangible asset related to customer relationships is amortized on a straight-line basis.

Nonoperating Components of Net Periodic Benefit Expense (Income)

Nonoperating components of net periodic benefit expense (income) netted to income of $4.4 million and $4.3 million in the three months ended September 30, 2022 and 2021, respectively, an increase of $0.1 million (or 2%).

Nonoperating components of net periodic benefit expense (income) consist primarily of the expected return on plan assets, offset by interest cost as the discounted present value of benefit obligations nears payment, as described in Note 8, Pension and Postretirement Health and Life Benefits of the Consolidated Financial Statements.

36

Income Tax Expense (Benefit)

Income tax benefit was $1.8 million and income tax expense was $0.4 million in the three months ended September 30, 2022 and 2021, respectively, a decrease of $2.2 million (or 550%). Income tax expense in all periods resulted from applying the annual effective tax rate to year-to-date income from continuing operations adjusted for discrete items; however, the company had minimal income tax expense for the three months ended September 30, 2021 as it was in a full federal valuation allowance. The Company had released a portion of its federal valuation allowance at the end of 2021 however the Company had a loss before income taxes and was not able to utilize any deferred tax assets for the three months ended September 30, 2022. For more information about the valuation allowance, see Note 13, Income Taxes, in our Consolidated Financial Statements on Form 10-K for the year ended December 31, 2021. Based on Centrus’ analysis, there was no change to the tax valuation allowance during the three months ended September 30, 2022.

Net Income (Loss)

Net loss was $6.1 million in the three months ended September 30, 2022, compared to net income of $42.1 million in the three months ended September 30, 2021, a decrease of $48.2 million (or 114%). The $48.2 million decrease in net income for the three months ended September 30, 2022 was primarily attributable to a $40.2 million decrease in gross profit from the Technical Solutions segment and a $7.0 million decrease in gross profit from the LEU segment. The decrease in gross profit from the Technical Solutions segment was driven by the $43.5 million of revenue in the three months ended September 30, 2021 related to the settlement of the Company’s claim for costs incurred in connection with a prior cost-reimbursable contract with DOE.

Amortization of Intangible Assets

Amortization of intangible assets was $6.2 million and $5.4 million in the nine months ended September 30, 2022 and 2021, respectively, an increase of $0.8 million (or 15%). Amortization expense for the intangible asset related to the September 2014 sales order book is a function of SWU sales volume under that order book, and amortization expense for the intangible asset related to customer relationships is amortized on a straight-line basis.

Nonoperating Components of Net Periodic Benefit Expense (Income)

Nonoperating components of net periodic benefit expense (income) netted to income of $11.1 million and $12.9 million for the nine months ended September 30, 2022 and 2021, respectively, a decrease of $1.8 million, or (14%). Nonoperating components of net periodic benefit expense (income) consist primarily of the expected return on plan assets, offset by interest cost as the discounted present value of benefit obligations nears payment, as described in Note 8, Pension and Postretirement Health and Life Benefits, of the Consolidated Financial Statements.

Income Tax Expense

Income tax expense was $9.3 million and $0.7 million in the nine months ended September 30, 2022 and 2021, respectively, an increase of $8.6 million (or 1229%). Income tax expense in all periods resulted from applying the annual effective tax rate to year-to-date income from continuing operations adjusted for discrete items; however, the company had minimal income tax expense for the nine months ended September 30, 2021 as it was in a full federal valuation allowance. The Company had released a portion of its federal valuation allowance at the end of 2021 which has enabled it to use its deferred tax assets for the income from continuing operations in the nine months ended September 30, 2022. For more information about the valuation allowance, see Note 13, Income Taxes, in our Consolidated Financial Statements on Form 10-K for the year ended December 31, 2021. Based on Centrus’ analysis, there was no change to the tax valuation allowance in the nine months ended September 30, 2022.

Net Income

Net income was $30.9 million and $58.8 million in the nine months ended September 30, 2022 and 2021, respectively, a decrease of $27.9 million (or 47%). The $27.9 million decrease in net income for the nine months ended September 30, 2022 was primarily attributable to a decrease in gross profit of $33.2 million in the Technical Solutions segment, an increase in Advanced Technology Costs of $8.7 million, and an increase in income tax expense of $8.6 million, discussed above. This was partially offset by an increase in gross profit of $24.4 million in the LEU segment. The decrease in gross profit from the Technical Solutions segment was driven by the $43.5 million of revenue in the nine months ended September 30, 2021 related to the settlement of the Company’s claim for costs incurred in connection with a prior cost-reimbursable contract with DOE.

Net Income (Loss) per Share

Refer to Note 9, Net Income (Loss) per Share, of the Consolidated Financial Statements.

The Company measures Net Income (Loss) and Net Income (Loss) per Share both on a GAAP basis and on an adjusted basis to exclude deemed dividends allocable to retired preferred stock shares (“Adjusted Net Income (Loss)” and “Adjusted Net Income (Loss) per Share”). We believe Adjusted Net Income (Loss) and Adjusted Net Income (Loss) 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

We ended the third quarter of 2022, with a consolidated cash balance of $131.7 million. We anticipate having adequate liquidity to support our business operations for at least the next 12 months from the date of this Quarterly Report. Our view of liquidity is dependent on, among other things, conditions affecting our operations, including market, international trade restrictions, COVID-19 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 sales 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 Contract with DOE in October 2019. Under the HALEU Contract, the Company contributed its required contribution through November 30, 2021. The program has been under way since May 31, 2019, when Centrus and DOE signed a preliminary letter agreement that allowed work to begin while the full contract was being finalized.

The Company entered into this cost-share contract with DOE as a critical first step on the road back to the commercial production of enriched uranium, which the Company had terminated in 2013 with the closure of the Paducah GDP. HALEU is expected to be required by many of the advanced reactor designs now under development, including nine out of the ten reactor designs that were selected in 2020 for the ARDP. Our HALEU Contract expires in November 2022, and although we believe demand for HALEU will emerge over the next several years, there are no guarantees about whether or when government or commercial demand for HALEU will materialize, and there are a number of technical, regulatory, and economic hurdles that must be overcome for these fuels and reactors to come to the market. If we win a contract from DOE to operate the cascade, our 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. For further discussion, refer to Part I, Item 1A, Risk Factors, in our Annual Report on Form 10-K for the year ended December 31, 2021, as updated by Part II, Item 1A, Risk Factors, in this Quarterly Report on Form 10-Q.

On June 28, 2022, the DOE released an RFP for the completion and operation of the demonstration cascade. If a contract is awarded to the Company under the terms proposed by DOE, the cost share could have a material impact on the Company’s liquidity during Phase 1 of the base contract but the degree of impact cannot be estimated at this time. If funding by the U.S. government for research, development and demonstration of gas centrifuge technology is reduced or discontinued, or we are not awarded a DOE contract to operate the cascade we are now constructing under the HALEU Contract, such actions may have a material adverse impact on our ability to deploy the American Centrifuge technology and on our liquidity.

Capital expenditures of approximately $1.0 million are anticipated over the next 12 months.

We are actively considering, and expect to consider from time to time in the future, potential strategic transactions, which at any given time may be in various stages of discussions, diligence, or negotiation. If we pursue opportunities that require capital, we believe 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):

	Nine Months Ended   September 30,
	2022		2021
Cash provided by (used in) operating activities	$	(35.1)	$	0.8
Cash used in investing activities	(0.6)		(0.7)
Cash provided by (used in) financing activities	(8.1)		18.9
Increase (decrease) in cash, cash equivalents and restricted cash	$	(43.8)	$	19.0

Operating Activities

In the nine months ended September 30, 2022, net cash used in operating activities was $35.1 million. The net decrease was due to an increase in payments made to suppliers of approximately $24.0 million as well as a decrease in cash collected from customers of approximately $24.0 million, which resulted from the timing of customer shipments and related contract terms. This remaining difference was primarily related to a reduction in disbursements from prior year for our Technical Solutions segment.

In the nine months ended September 30, 2021, net cash provided by operating activities was $0.8 million. Net income of $58.8 million in the nine-month period, net of non-cash expenses, was a significant source of cash. Income included the $43.5 million recovery of claims for reimbursement for costs related to past contract services performed. The net increase is also the result of the $12.7 million decrease in accounts receivable. The increase in cash is partially offset by a net reduction of $7.8 million in deferred revenue and advances from customers which reflects revenue recognized in the current period related to payments received in advance in a prior period. Uses of cash are also reflected in the decrease in pension and postretirement benefit liabilities of $55.3 million and the decrease in payables under SWU purchase agreements of $19.0 million.

Investing Activities

Capital expenditures were $0.6 million and $0.7 million in the nine months ended September 30, 2022 and 2021, respectively.

Financing Activities

In both the nine months ended September 30, 2022 and 2021, payments of $6.1 million of interest classified as debt are classified as a financing activity. Refer to Note 6, Debt, of the Consolidated Financial Statements regarding the accounting for the 8.25% notes (the “8.25% Notes”) maturing in February 2027. In the nine months ended September 30, 2021, net cash provided by financing activities also included net proceeds of $27.2 million raised from the issuance of common stock pursuant to a Registration Statement on Form S-3.

Working Capital

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

	September 30, 2022		December 31, 2021
Cash and cash equivalents	$	131.7	$	193.8
Accounts receivable	7.4		29.1
Inventories, net	133.9		82.7
Current debt	(6.1)		(6.1)
Deferred revenue and advances from customers, net of deferred costs	(129.6)		(159.8)
Other current assets and liabilities, net	(26.3)		(67.1)
Working capital	$	111.0	$	72.6

We are managing our working capital to seek to improve the long-term value of our LEU and Technical Solutions businesses and are planning to continue funding the Company’s qualified pension plans in the ordinary course 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.

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 6, Debt, of the Consolidated Financial Statements and Note 8, Debt, of the Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.

Commitments under Long-Term SWU Purchase Agreements

Refer to Note 11, Commitments and Contingencies, of the Consolidated Financial Statements for additional information.

DOE Technology License

We have a non-exclusive license in DOE inventions that pertain to enriching uranium using gas centrifuge technology. The license agreement with 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 us 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 facilities in Oak Ridge, Tennessee, 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 DOE relating to the American Centrifuge technology, there were no material off-balance sheet arrangements at September 30, 2022.

PART II

Item 1. Legal Proceedings

Refer to Note 11, Commitments and Contingencies — Legal Matters, of our Consolidated Financial Statements in Part I of this Quarterly Report.

Item 1A. Risk Factors

Except as set forth below, there have been no material changes to the Risk Factors described in Part I, Item 1A, Risk Factors, in our Annual Report on Form 10-K for the year ended December 31, 2021.

The current war in Ukraine and related international sanctions and restrictions on trade could have an adverse impact on our business, results of operations, and financial condition.

The current war in Ukraine has led the United States, Russia, and other countries to impose sanctions and other measures that restrict international trade. At present, sanctions have not directly impacted the ability of the Company or TENEX to perform under the TENEX Supply Contract, but the situation is rapidly changing, and it is not possible to predict future actions that could be taken.

The expanding sanctions imposed by the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) and foreign governments on Russian banks or other entities and instrumentalities needed for performance of the TENEX Supply Contract could have adverse effects on the TENEX Supply Contract, even if such sanction is not directed at imports of Russian LEU or other trade in nuclear material with Russia. For example, a sanction on a Russian bank might prevent funds from being transferred to TENEX’s account from the U.S. bank to which we make payments. We do not know what actions TENEX might take if it could not receive payments in Russia, but if it refused to make future deliveries, such action could affect our ability to meet our delivery obligations to our customers.

Further, sanctions by the United States, Russia or other countries may impact performance of the TENEX Supply Contract and our ability to transport, import, take delivery or make payments related to the LEU we purchase. For example in June 2022, Canada prohibited Canadian entities from providing transportation services to Russians or persons in Russia in various industries, including enrichment of uranium. A company that provides transportation services to the Company under the TENEX Supply Contract interpreted the sanction as applying to transporting of Russian LEU for the Company, and the Canadian company informed the Company that it could not load Russian LEU until it received a permit from the Canadian government. Although the permit was issued, it is only valid for one year, meaning that, absent a renewal of the permit, the Company will need to find an alternative transportation company, which may be difficult and costly because of the limited number of qualified providers. Further, adverse consequences for future deliveries of Russian LEU could result if companies who are closely involved in the U.S. nuclear fuel cycle (including, for example, the supply of the natural uranium used to return the uranium component of Russian LEU to TENEX), are prevented from performing and making such natural uranium available to TENEX for return to Russia, as required by the terms of the Russian Suspension Agreement. In addition, companies that provide us with services essential to implementation of the TENEX Supply Contract, including but not limited to companies affected by sanctions from countries such as Canada, conclude that for reasons of risk or cost, they no longer can provide those services to us.

The uncertainty created by the Canadian sanctions and the lack of options for alternative suppliers illustrates the fact that even if sanctions or other restrictions are not imposed, the reaction of the U.S. and foreign governments to current events in Ukraine could impact our ability to make future sales or meet our existing obligations. In addition, uncertainty in the market will tend to push market prices up, and since a portion of the price paid under our TENEX Supply Contract is based on commodity indices, an increase in market prices will have a corresponding impact on our cost of sales.

44

Additional sanctions or other measures by the U.S. or foreign governments (including the Russian government) could be imposed in the future. There have been proposals in U.S. Congress and elsewhere to ban imports of uranium that could affect our ability to import LEU in one or more years under the TENEX Supply Contract but none of these have been adopted as of the date of this filing. Any sanctions or measures directed at trade in LEU from Russia or the parties involved in such trade or otherwise could interfere with, or prevent, performance under the TENEX Supply Contract. Accordingly, the situation at this time is unpredictable and therefore there is no assurance that future developments would not have a material adverse effect on the Company’s procurement, payment, delivery or sale of LEU by the Company.

If measures were taken to limit the import of Russian LEU or to prohibit or limit dealings with Russian entities, including, but not limited to, TENEX or the Russian State Atomic Energy Corporation, 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 using LEU delivered under the TENEX Supply Contract. There is no assurance that such a license, waiver, or approval would be granted. If a license, waiver, or approval were not granted, the Company would need to look to alternative sources of LEU to replace the LEU that it could not procure from TENEX. The Company has contracts for alternative sources that could be used to mitigate a portion of the near-term impacts. However, to the extent these sources were insufficient or more expensive or additional supply cannot be obtained, it could have a material adverse impact on our business, results of operations, and competitive position.

The current uncertainty regarding trade with Russia, as well as the actions of Russia in the war against Ukraine, may affect our ability to make future sales. Additionally, customers may seek to re-negotiate existing contracts, refuse to take deliveries of Russian LEU, or take other actions which could have a material adverse impact on our business, results of operations, and competitive position. Finally, since the majority of our supply contracts include a market-based pricing component, the rapidly rising market prices due to the war in Ukraine and the associated sanctions could materially increase our cost of sales under our existing supply contracts, including but not limited to, the TENEX Supply Contract.

If at any time such security is not listed on any domestic securities exchange or quoted in the domestic over-the- counter market, the “Market Price” shall be determined in good faith by the Board of Directors of the Company. 2. EXERCISE OF WARRANT. The rights represented by this Warrant may be exercised in whole at any time during the Exercise Period by delivery of the following to the

3 Company at its address set forth on the signature page hereto (or at such other address as it may designate by notice in writing to the Holder): (a) An executed notice of exercise in the form attached hereto (the “Notice of Exercise”); (b) Payment of the Exercise Price either in cash or by check; and (c) This Warrant for cancellation. As an alternative to the exercise of this Warrant by payment the Exercise Price as provided above, the Holder may elect to exchange all or part of the purchase rights represented by this Warrant by surrendering this Warrant to the Company, together with a written notice to the Company that the holder is exchanging the Warrant (or a portion thereof) for an aggregate number of shares of Common Stock specified in the Notice of Exercise, from which the Company shall withhold and not issue to the holder a number of shares of Common Stock with an aggregate Market Price equal to the Exercise Price for the number of shares of Warrant Stock specified in such notice (and such withheld shares shall no longer be issuable under this Warrant). The exercise of the option described in this paragraph is referred to as a “Cashless Exercise.” The Company shall deliver any objection to any Notice of Exercise within two (2) Business Days of receipt of such notice. In the event of any discrepancy or dispute, the records of the Company shall be controlling and determinative in the absence of manifest error. Certificates for shares purchased hereunder shall be transmitted by the transfer agent of the Company to the Holder by crediting the account of the Holder’s prime broker with the Depository Trust Company (“DTC”) through its Deposits and Withdrawal at Custodian (DWAC) system if the Company is a participant in such system, or otherwise through book-entry recordation by the Company’s transfer agent, or physical delivery to the address specified by the Holder in the Notice of Exercise as soon as practicable after the delivery to the Company of the Notice of Exercise (the “Share Delivery Date”), the surrender of this Warrant and the payment of the aggregate Exercise Price as set forth above. This Warrant shall be deemed to have been exercised on the date the Exercise Price is received by the Company (or, in the case of Cashless Exercise, the date the Company receives the Notice of Exercise in respect of such Cashless Exercise). The Exercise Shares shall be deemed to have been issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date this Warrant has been exercised by payment to the Company of the Exercise Price and surrender of this Warrant by the Holder, irrespective of the date of delivery of the Exercise Shares, except that, if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the stock transfer books are open. 3. COVENANTS OF THE COMPANY. 3.1 COVENANTS AS TO EXERCISE SHARES.

4 (a) The Company covenants and agrees that all Exercise Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued and outstanding, fully paid and nonassessable, and free from all taxes, liens and charges with respect to the issuance thereof. (b) The Company further covenants and agrees that the Company will at all times during the Exercise Period, have authorized and reserved, free from preemptive rights, a sufficient number of shares of Common Stock to provide for the exercise of the rights represented by this Warrant. If at any time during the Exercise Period the number of authorized but unissued shares of Common Stock shall not be sufficient to permit exercise of this Warrant, the Company will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes. 3.2 NOTICES OF RECORD DATE AND CERTAIN OTHER EVENTS. In the event of any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, the Company shall mail to the Holder, at least ten (10) days prior to the date on which any such record is to be taken for the purpose of such dividend or distribution, a notice specifying such date. In the event of any voluntary dissolution, liquidation or winding up of the Company, the Company shall mail to the Holder, at least ten (10) days prior to the date of the occurrence of any such event, a notice specifying such date. In the event the Company authorizes or approves, enters into any agreement contemplating, or solicits stockholder approval for any Fundamental Transaction, as defined in Section 1 herein, the Company shall mail to the Holder, at least ten (10) days prior to the date of the occurrence of such event, a notice specifying such date. 4. COVENANTS OF THE HOLDER. 4.1 AUTHORIZATION. The Holder hereby represents and warrants that it has full power and authority to enter into this Warrant and such Warrant constitutes its valid and legally binding obligations, enforceable in accordance with its terms. 4.2 PURCHASE FOR OWN ACCOUNT. The Holder acknowledges that this Warrant is issued to the Holder in reliance upon the Holder’s representation to the Company, which by the Holder’s execution of this Warrant the Holder hereby confirms, that this Warrant and the Exercise Shares (collectively, the “Securities”) will be acquired for investment for the Holder’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that the Holder has no present intention of selling, granting any participation in or otherwise distributing the same. By executing this Warrant, the Holder represents that it does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participations to such person or to any third person, with respect to any of the Securities. The Holder also represents that it has not been organized for the specific purpose of acquiring the Securities. 4.3 DISCLOSURE OF INFORMATION. The Holder acknowledges that it has received all of the information it considers necessary or appropriate for deciding whether to purchase the Securities. The Holder further represents that it has had an opportunity to ask questions and

5 receive answers from the Company regarding the terms and conditions of this Warrant and the business, properties, prospects and financial condition of the Company. 4.4 INVESTMENT EXPERIENCE. The Holder hereby represents and warrants that it is an investor in securities of companies and acknowledges that it can bear the economic risk of its investment, and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in the Securities. 4.5 ACCREDITED INVESTOR. The Holder hereby represents and warrants that it is an “accredited investor” within the meaning of the Securities and Exchange Commission (“SEC”) Rule 501 of Regulation D, as presently in effect. 4.6 RESTRICTED SECURITIES. (a) The Holder understands and acknowledges that the Securities are characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such Securities may be resold without registration under the Securities Act only in certain limited circumstances. In the absence of an effective registration statement covering the Securities or an available exemption from registration under the Securities Act, the Securities must be held indefinitely. The Holder represents that it is familiar with SEC Rule 144 (“Rule 144”) as presently in effect and understands the resale limitations imposed thereby and by the Securities Act. (b) The Exercise Shares shall be stamped or imprinted with a legend substantially similar to the following (in addition to any legend required by state securities laws): THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED EXCEPT AS PERMITTED UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS IN ACCORDANCE WITH APPLICABLE REGISTRATION REQUIREMENTS OR AN EXEMPTION THEREFROM. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER THAT SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION OTHERWISE COMPLIES WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS. THIS CERTIFICATE MUST BE SURRENDERED TO THE COMPANY OR ITS TRANSFER AGENT AS A CONDITION PRECEDENT TO THE SALE, TRANSFER, PLEDGE OR HYPOTHECATION OF ANY INTEREST IN ANY OF THE SECURITIES REPRESENTED HEREBY. (c) The Holder covenants that in no event will the Holder dispose of any of the Securities other than in conjunction with an effective registration statement for the Securities under the Securities Act or in compliance with Rule 144 unless and until (i)(A) the Holder shall have

6 notified the Company of the proposed disposition and shall have furnished the Company with a statement of the circumstances surrounding the proposed disposition and (B) the Holder shall have furnished the Company with an opinion of counsel satisfactory in form and substance to the Company to the effect that (x) such disposition will not require registration under the Securities Act and (y) appropriate action necessary for compliance with the Securities Act and any other applicable state, local or foreign law has been taken or (ii) the Company shall have received a letter secured by the Holder from the SEC stating that no action will be recommended to the SEC with respect to the proposed disposition. 5. ADJUSTMENT OF EXERCISE PRICE AND SHARES. (a) In the event of changes in the outstanding Common Stock of the Company by reason of stock dividends, split-ups, recapitalizations, reclassifications, combinations or exchange of shares, separations, reorganizations, liquidations, consolidation, acquisition of the Company (whether through merger or acquisition of substantially all the assets or stock of the Company), or the like, the number, class and type of shares available under this Warrant in the aggregate and the Exercise Price shall be correspondingly adjusted to give the Holder of this Warrant, on exercise for the same aggregate Exercise Price, the total number, class, and type of shares or other property as the Holder would have owned had this Warrant been exercised prior to the event and had the Holder continued to hold such shares until the event requiring adjustment. The form of this Warrant need not be changed because of any adjustment in the number of Exercise Shares subject to this Warrant. (b) If at any time or from time to time the holders of Common Stock of the Company (or any shares of stock or other securities at the time receivable upon the exercise of this Warrant) shall have received or become entitled to receive, without payment therefor, (i) Common Stock or any shares of stock or other securities which are at any time directly or indirectly convertible into or exchangeable for Common Stock, or any rights or options to subscribe for, purchase or otherwise acquire any of the foregoing by way of dividend or other distribution (other than a dividend or distribution covered in Section 5(a) above); (ii) any cash paid or payable otherwise than as a cash dividend; or (iii) Common Stock or additional stock or other securities or property (including cash) by way of spinoff, split-up, reclassification, combination of shares or similar corporate rearrangement (other than shares of Common Stock pursuant to Section 5(a) above), then and in each such case, the Holder hereof will, upon the exercise of this Warrant, be entitled to receive, in addition to the number of shares of Common Stock receivable thereupon, and without payment of any additional consideration therefor, the amount of stock and other securities and property (including cash in the cases referred to in clauses (ii) and (iii) above) which such Holder would hold on the date of such exercise had such Holder been the holder of record of such Common Stock as of the date on which holders of Common Stock received or became entitled to receive such shares or all other additional stock and other securities and property.

7 (c) Upon the occurrence of each adjustment pursuant to this Section 5, the Company at its expense will, at the written request of the Holder, promptly compute such adjustment in accordance with the terms of this Warrant and prepare a certificate describing the transactions giving rise to and setting forth in reasonable detail the calculation of such adjustment, including a statement of the adjusted Exercise Price and adjusted number or type of Exercise Shares or other securities issuable upon exercise of this Warrant (as applicable). The Company will promptly deliver a copy of each such certificate to the Holder and to the Company’s transfer agent. 6. FRACTIONAL SHARES. No fractional shares shall be issued upon the exercise of this Warrant as a consequence of any adjustment pursuant hereto. All Exercise Shares (including fractions) issuable upon exercise of this Warrant may be aggregated for purposes of determining whether the exercise would result in the issuance of any fractional share. If, after aggregation, the exercise would result in the issuance of a fractional share, the Company shall, at its election, either pay the Holder otherwise entitled to such fraction a sum in cash equal to the product resulting from multiplying the then current fair market value of an Exercise Share by such fraction or the number of Exercise Shares to be issued shall be rounded up or down, as applicable, to the nearest whole number. 7. NO STOCKHOLDER RIGHTS. Other than as provided in Section 3.2 or otherwise herein, this Warrant in and of itself shall not entitle the Holder to any voting rights or other rights as a stockholder of the Company. 8. TRANSFER OF WARRANT. Subject to compliance with any applicable laws, this Warrant and all rights hereunder are transferable, by the Holder in person or by duly authorized attorney, upon delivery of this Warrant and the form of assignment attached hereto to any transferee designated by Holder. The transferee shall sign an investment letter in form and substance reasonably satisfactory to the Company and its counsel. 9. LOST, STOLEN, MUTILATED OR DESTROYED WARRANT. If this Warrant is lost, stolen, mutilated or destroyed, the Company may, on such terms as to indemnity or otherwise as it may reasonably impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination and tenor as this Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute an original contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone. 10. NOTICES, ETC. All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed email or facsimile if sent during normal business hours of the recipient, if not, then on the next Business Day, (c) five days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of

BASIS OF PRESENTATION

Basis of Presentation and Principles of Consolidation

The unaudited Consolidated Financial Statements of Centrus Energy Corp. (“Centrus” or the “Company”), which include the accounts of the Company, its principal subsidiary, United States Enrichment Corporation, and its other subsidiaries, as of September 30, 2022, and for the three and nine months ended September 30, 2022, and 2021, have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The unaudited Consolidated Balance Sheet as of December 31, 2021, was derived from audited Consolidated Financial Statements, but does not include all disclosures required by generally accepted accounting principles in the United States (“GAAP”). In the opinion of management, the unaudited Consolidated Financial Statements reflect all adjustments, including normal recurring adjustments, necessary for a fair statement of the financial results for the interim period. Certain prior year amounts have been reclassified for consistency with the current year presentation. Certain information and notes normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to such rules and regulations. All material intercompany transactions have been eliminated. The Company’s components of comprehensive income for the three and nine months ended September 30, 2022 and 2021, are insignificant.

Operating results for the three and nine months ended September 30, 2022, are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. The unaudited Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and related notes and Management's Discussion and Analysis of Financial Condition and Results of Operations included in the Annual Report on Form 10-K for the year ended December 31, 2021.

Significant Accounting Policies

The accounting policies of the Company are set forth in Note 1 to the Consolidated Financial Statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. There has not been a material change to the Company’s accounting policies since that report.

REVENUE AND CONTRACTS WITH CUSTOMERS

Disaggregation of Revenue

The following table presents revenue from separative work units (“SWU”) and uranium sales disaggregated by geographical region based on the billing addresses of customers (in millions):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2022		2021		2022		2021
United States	$	7.4	$	13.8	$	27.3	$	68.6

Revenue - SWU and uranium	$	20.2	$	32.0	$	123.4	$	115.3

Refer to Note 12, Segment Information, for disaggregation of revenue by segment. SWU sales are made primarily to electric utility customers and uranium sales are made primarily to other nuclear fuel related companies. Technical Solutions revenue resulted primarily from services provided to the government and its contractors. SWU

and uranium revenue is recognized at point of sale and Technical Solutions revenue is generally recognized over time.

Accounts Receivable

Accounts receivable:
Billed	$	2.0	$	23.1
Unbilled *	5.4		6.0
Accounts receivable	$	7.4	$	29.1
* Billings under certain contracts in the Technical Solutions segment are invoiced based on approved provisional billing rates. Unbilled revenue represents the difference between actual costs incurred and invoiced amounts. The Company expects to invoice and collect the unbilled amounts after actual rates are submitted to the customer and approved. Unbilled revenue also includes unconditional rights to payment that are not yet billable under applicable contracts pending the compilation of supporting documentation.

Contract Liabilities

The following table presents changes in contract liability balances (in millions):

Advances from customers - current	$	15.3	$	15.0	$	0.3
Advances from customers - noncurrent	$	46.2	$	45.1	$	1.1

Previously deferred sales recognized in revenue totaled $59.7 million and $28.5 million in the nine months ended September 30, 2022 and 2021, respectively.

LEU Segment

The SWU component of low-enriched uranium (“LEU”) typically is bought and sold under contracts with deliveries over several years. The Company’s agreements for natural uranium sales generally are shorter-term, fixed-commitment contracts. The Company’s order book of sales under contract in the LEU segment (“order book”) extends to 2029. As of September 30, 2022, the order book was approximately $1.0 billion. The order book represents the estimated aggregate dollar amount of revenue for future SWU and uranium deliveries under contract and includes approximately $311.1 million of Deferred Revenue and Advances from Customers. As of December 31, 2021, the order book was also approximately $1.0 billion.

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

Technical Solutions Segment

Revenue for the Technical Solutions segment, representing the Company’s 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.

On October 31, 2019, the Company signed a cost-share contract with the U.S. Department of Energy (“DOE”) (the “HALEU Contract”) to deploy a cascade of centrifuges to demonstrate production of high-assay, low-enriched uranium (“HALEU”) for advanced reactors. HALEU is a component of an advanced nuclear reactor fuel that is not commercially available today and may be required for a number of advanced reactor and fuel designs currently under development in both the commercial and government sectors. The program has been under way since May 31, 2019, when the Company and DOE signed a preliminary letter agreement that allowed work to begin while the full contract was being finalized.

In 2019, under the HALEU Contract, DOE agreed to reimburse the Company for 80% of its costs incurred in performing the contract. The DOE has modified the contract several times to increase the total contract funding to $156.3 million as of September 30, 2022. Subsequent to September 30, 2022, an additional modification increased the total contract funding to $158.9 million. In April 2022, the DOE modified the HALEU Contract to extend the period of performance to November 30, 2022. Costs under the HALEU Contract include program costs, including direct labor and materials and associated indirect costs that are classified as Cost of Sales, and an allocation of corporate costs supporting the program that are classified as Selling, General and Administrative Expenses. The impact to Cost of Sales in the nine months ended September 30, 2022 and 2021, is $0.5 million and $6.5 million, respectively, for previously accrued contract losses attributable to work performed in the periods. As of September 30, 2022, a total of $19.6 million of previously accrued contract losses have been realized and the accrued contract loss balance included in Accounts Payable and Accrued Liabilities is $0. The Company has received aggregate cash payments under the HALEU Contract of $155.1 million through September 30, 2022.

As previously reported, the DOE experienced a COVID-19 related supply chain delay in obtaining the HALEU storage cylinders. As a result, the DOE elected to change the scope of the existing contract and move the operational portion of the demonstration to a new, competitively-awarded contract. The Company does not currently have a contractual obligation to perform work in excess of the funding provided by DOE. If the DOE does not commit to additional costs above the existing funding, the Company may incur material additional costs or losses in future periods that could have an adverse impact on its financial condition and liquidity.

On June 28, 2022, the DOE released a request for proposals (“RFP”) for the completion and operation of the demonstration cascade. The RFP provides for a 50/50 cost share contract for the initial phase to complete the cascade and produce 20 kg of HALEU. Once 20 kg of HALEU has been produced, the base contract will transition to a cost-plus-incentive-fee contract for production of 900 kg over the subsequent 1-year period. The RFP includes options held by the DOE to extend performance up to an additional nine years, comprised of three options of three-years each, also on a cost-plus-incentive-fee basis.

Revenue for the Technical Solutions segment in the three and nine months ended September 30, 2021, also includes $43.5 million related to the settlement of the Company’s claims for reimbursements for certain pension and postretirement benefits costs incurred in connection with a past cost-reimbursable contract with DOE unrelated to the HALEU Contract. Under the terms of the settlement agreement, DOE paid the Company $43.5 million, of which $33.8 million was contributed to the pension plan in September 2021 for its subsidiary United States Enrichment Corp. (“Enrichment Corp.”) and $9.7 million was deposited in October 2021 in a trust for payment of postretirement health benefits payable by Enrichment Corp. After receiving payment, at the Company’s request, the case was dismissed.

The Company has provided financial assurance to states in which it was previously self-insured for workers’ compensation in accordance with each state’s requirements in the form of a surety bond or deposit that is fully cash collateralized by Centrus. Each surety bond or deposit is subject to reduction and/or cancellation, as each state determines the likely reduction of workers’ compensation obligations pertaining to the period of self-insurance. In March and May 2022, the Company entered into two inventory loans which required a cash deposit into an escrow fund. See Note 4, Inventories.

INVENTORIES

Centrus holds uranium at licensed locations (e.g., fabricators) in the form of natural uranium and as the uranium component of LEU. Centrus also holds SWU as the SWU component of LEU at licensed locations to meet book transfer requests by customers and suppliers. Fabricators process LEU into fuel for use in nuclear reactors. Components of inventories are as follows (in millions):

	September 30, 2022						December 31, 2021
	Current Assets		Current Liabilities (a)		Inventories, Net		Current Assets		Current Liabilities (a)		Inventories, Net

Total	$	209.3	$	75.4	$	133.9	$	91.1	$	8.4	$	82.7

(a)This includes inventories owed to suppliers for advances of uranium.

Inventories are valued at the lower of cost or net realizable value. There were no valuation adjustments in the three and nine months ended September 30, 2022 and 2021.

The Company may also borrow SWU or uranium from customers or suppliers, in which case the Company will record the SWU and/or uranium and the related liability for the borrowing using a projected and forecasted purchase price over the borrowing period. In March and May 2022, the Company borrowed SWU which was recorded to inventory at a value of $9.4 million and $8.5 million, respectively. The inventory value was calculated based on the anticipated sourcing of inventory for repayment at the date of acquisition. In June 2022, the Company performed a revaluation of the Long-term Inventory Loans reflecting an updated projection of the timing and sources of inventory to be used for repayment. This revaluation was recorded to Cost of Sales and resulted in an increase of $5.5 million to the related liability. In October 2022, the Company borrowed additional SWU which was collateralized by restricted cash of $11.2 million.

In 2018 through 2020, the Company borrowed SWU inventory valued at $20.7 million. The cumulative liability was revalued to $25.5 million in the third quarter of 2021 to reflect an updated projection of the timing and sources of inventory to be used for repayment. Cost of Sales for the three and nine months ended September 30, 2021, includes the related expense of $4.8 million.

Intangible Assets

INTANGIBLE ASSETS

Intangible assets originated from the Company’s reorganization and application of fresh start accounting as of the date the Company emerged from bankruptcy, September 30, 2014, and reflect the conditions at that time. The intangible asset related to the Company’s sales order book is amortized as the order book, existing at emergence, is reduced, principally as a result of deliveries to customers. The intangible asset related to customer relationships is amortized using the straight-line method over the estimated average useful life of 15 years. Amortization expense is presented below gross profit on the Consolidated Statements of Operations and Comprehensive Income. Intangible asset balances are as follows (in millions):

Fair Value Disclosures [Abstract]

Fair Value Measurements

FAIR VALUE

Fair value is 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 of assets and liabilities, the following hierarchy is used in selecting inputs, with the highest priority given to Level 1, as these are the most transparent or reliable:

•Level 1 assets include investments with quoted prices in active markets that the Company has the ability to liquidate as of the reporting date.

•Level 2 assets include investments in U.S. government agency securities, corporate and municipal debt whose estimates are valued based on observable inputs, other than quoted prices.

•Level 3 assets include investments with unobservable inputs, such as third-party valuations, due to little or no market activity.

Financial Instruments Recorded at Fair Value (in millions):

	September 30, 2022								December 31, 2021

(a)    The deferred compensation obligation represents the balance of deferred compensation plus net investment earnings. The deferred compensation plan is funded through a rabbi trust. Trust funds are invested in mutual funds for which unit prices are quoted in active markets and are classified within Level 1 of the valuation hierarchy.

There were no transfers between Level 1, 2 or 3 during the periods presented.

Other Financial Instruments

As of September 30, 2022, and December 31, 2021, the Consolidated Balance Sheets carrying amounts for Accounts Receivable, Accounts Payable and Accrued Liabilities (excluding the deferred compensation obligation described above), and Payables under Inventory Purchase Agreements approximate fair value because of their short-term nature.

Earnings Per Share [Abstract]

Net Income (Loss) Per Share

NET INCOME (LOSS) PER SHARE

Basic net income (loss) per share is calculated by dividing income (loss) allocable to common stockholders by the weighted average number of shares of common stock outstanding during the period. In calculating diluted net income (loss) per share, the number of shares is increased by the weighted average number of potential shares related to stock compensation awards. No dilutive effect is recognized in a period in which a net loss has occurred.

On February 2, 2021, the Company completed the exchange of 3,873 shares of its outstanding Series B Senior Preferred Stock, par value $1.00 per share (“Preferred Stock”) for (i) 231,276 shares of Class A Common Stock and (ii) a warrant to purchase 250,000 shares of Class A Common Stock at an exercise price of $21.62 per share, for an aggregate valuation of approximately $7.5 million. Refer to Note 10, Stockholders’ Equity.

The aggregate valuation of approximately $7.5 million, less accrued but unpaid dividends attributable to the acquired and retired shares of Preferred Stock, was considered for purposes of Net Income per Share for the nine months ended September 30, 2021, to be a deemed dividend in the aggregate amount equal to the amount by which it exceeded the carrying value of the Preferred Stock on the Balance Sheet of $6.6 million.

The weighted average number of common and common equivalent shares used in the calculation of basic and diluted income (loss) per share are as follows:

STOCKHOLDERS’ EQUITY

Common Stock Issuance

Pursuant to a sales agreement with its agents, the Company sold, through its At-the-Market (ATM) offering at the market price, an aggregate of 1,238,637 shares of its Class A Common Stock in the nine months ended September 30, 2021, for a total of $28.7 million. After expenses and commissions paid to the agents, the Company’s proceeds totaled $27.6 million. Additionally, the Company recorded direct costs of $0.4 million related to the issuance. The shares of Class A Common Stock were issued pursuant to the Company’s shelf registration statement on Form S-3 (File No. 333-239242), which became effective on August 5, 2020, and a supplement dated December 31, 2020, to the prospectus. The Company has used and/or intends to use the net proceeds from this offering for general working capital purposes, to invest in technology development and deployment and to repay outstanding debt.

Voting and Exchange Agreement

On February 2, 2021, the Company entered into an amendment (the “Voting Agreement Amendment”) to its existing Voting and Nomination Agreement with Mr. Morris Bawabeh, Kulayba LLC and M&D Bawabeh Foundation, Inc. (collectively, the “MB Group”) and an Exchange Agreement (as described below) whereby the MB Group agreed to support management’s recommendation on certain matters at the Company’s 2021 annual meeting of stockholders (the “Annual Meeting”) and Kulayba LLC agreed to exchange shares of the Company’s Preferred Stock for shares of the Company’s Class A Common Stock and a warrant to acquire additional shares of Class A Common Stock.

The Company and Kulayba LLC also entered into an Exchange Agreement, dated February 2, 2021 (the “Exchange Agreement”), pursuant to which Kulayba LLC agreed to exchange (the “Exchange”) 3,873 shares of

Preferred Stock, 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 of the Exchange Agreement and (ii) a Centrus Energy Corp. Warrant to Purchase Class A Common Stock (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 of the Exchange Agreement, subject to certain customary adjustments pursuant to the terms of the Warrant. The Warrant is exercisable by Kulayba LLC, unless terminated as provided in the Warrant, or the first to occur: (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 stockholders 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 October 17, 2022, the Company and Kulayba LLC amended the Warrant to permit the cashless exercise of the Warrant, whereby shares valued at the closing price on the day of the exercise would be withheld to pay the exercise price.

Awards under Executive Incentive Plan

Notional stock units are a component of the 2019 Executive Incentive Plan for participating executives for the three-year period ending December 31, 2021. The plan payouts were settled in Class A Common Stock in April 2021 and March 2022. In April 2020, notional stock units and stock appreciation rights were granted to participating executives with a vesting period ending in April 2023.

Prior to 2022, these awards were determined to be likely settled in cash, and thus compensation cost for the notional stock units and stock appreciation rights were re-measured each reporting period based on the trading price of the Company’s Class A Common Stock and the cumulative vested costs were accrued in Accounts Payable and Accrued Liabilities or Other Long-Term Liabilities.

A portion of the April 2021 interim payment related to the 2019 grants referenced above was paid in shares of the Company’s Class A Common Stock at the discretion of the Board of Directors. The related obligation of $7.5 million was reclassified from Accounts Payable and Accrued Liabilities to Excess of Capital over Par Value in the first quarter of 2021 based on the market share price at the time of the Board of Directors’ decision. In the second quarter of 2021, the Company withheld $2.4 million of shares to fund the grantees’ tax withholding obligations relating to the April 2021 interim payment.

In September 2021, notional stock units and stock appreciation rights were granted to participating executives with a vesting period ending in April 2024. The September 2021 awards are payable in shares of the Company’s Class A Common Stock and the grant-date value is included in Excess of Capital Over Par Value as the value is amortized over the vesting period.

In February 2022, the Compensation, Nominating and Governance Committee of the Board of Directors determined that remaining notional stock units granted in 2019 and 2020 would be paid in shares of the Company’s Class A Common Stock. The related obligation of $10.6 million was reclassified from Accounts Payable and Accrued Liabilities to Excess of Capital over Par Value in the first quarter of 2022 based on the market share price at the time of the Board’s decision. In the first quarter of 2022, the Company withheld $1.9 million of shares that vested during the period for the purpose of funding the grantees’ tax withholding obligations under the terms of the stock-based compensation plan.

In March 2022, restricted stock was granted to participating executives with a vesting period ending in March 2025. The March 2022 awards are payable in shares of the Company’s Class A Common Stock and the grant-date value is included in Excess of Capital Over Par Value as the value is amortized over the vesting period.

Commitments and Contingencies

COMMITMENTS AND CONTINGENCIES

Commitments under SWU Purchase Agreements

TENEX

The Russian government-owned entity TENEX, Joint-Stock Company (“TENEX”), is a major supplier of SWU to the Company. Under a 2011 agreement with TENEX, as amended, (the “TENEX Supply Contract”), the Company purchases SWU contained in LEU received from TENEX, and the Company delivers natural uranium to TENEX for the LEU’s uranium component. The LEU that the Company obtains from TENEX is subject to quotas and other restrictions applicable to commercial Russian LEU. Further, the ability of the Company or TENEX to perform under the TENEX Supply Contract is vulnerable to (i) sanctions or restrictions that might be imposed by Russia, the United States, or other countries, as a result of the war in Ukraine, or otherwise, (ii) customers and other parties who may object to receiving or handling Russian LEU or SWU, or (iii) suppliers and service providers seeking to limit their involvement with business related to Russia.

The TENEX Supply Contract originally was signed with commitments through 2022, but was modified in 2015 to give the Company the right to reschedule certain quantities of SWU of the original commitments into the period 2023 and beyond, in return for the purchase of additional SWU in those years. The Company has exercised this right to reschedule in each year through December 31, 2022. As a result of exercising this right to reschedule, the Company will have purchase commitments that could extend through 2028.

The TENEX Supply Contract provides that the Company must pay for all SWU in its minimum purchase obligation each year, even if it fails to submit orders for such SWU. In such a case, the Company would pay for the SWU, but have to take the unordered SWU in the following year.

Pricing terms for SWU under the TENEX Supply Contract are based on a combination of market-related price points and other factors. This formula was subject to an adjustment at the end of 2018 that reduced the unit costs of SWU under this contract in 2019 and for the duration of the contract.

Orano

In 2018, the Company entered into an agreement (the “Orano Supply Agreement”) with the French company Orano Cycle for the long-term supply to the Company of SWU contained in LEU. The Orano Supply Agreement subsequently was assigned by Orano Cycle to its affiliate, Orano CE (“Orano”). Under the amended Orano Supply Agreement, the supply of SWU runs through 2030. The Orano Supply Agreement provides significant flexibility to adjust purchase volumes, subject to annual minimums and maximums in fixed amounts that vary year by year. The pricing for the SWU purchased by the Company is determined by a formula that uses a combination of market-related price points and other factors and is subject to certain floors and ceilings. 

Russian Suspension Agreement

Beginning in September 2022, the Russian Suspension Agreement is subject to two “sunset” reviews being conducted by the U.S. Department of Commerce (“DOC”) and the U.S. International Trade Commission (“ITC”), respectively, that will determine if the Russian Suspension Agreement should be maintained. These “sunset” reviews are required to be conducted every five years. This is the fifth round of “sunset reviews” of the Russian Suspension Agreement. The last round of reviews in 2016-17 concluded that termination of the Russian Suspension Agreement would lead to the continuation or recurrence of dumping of French LEU (a determination made by the DOC), and to the continuation or recurrence of material injury to the U.S. uranium industry (a determination made by the ITC), which resulted in the Russian Suspension Agreement being maintained. Even if the Russian Suspension Agreement were terminated as a result of the “sunset” reviews, the quotas under the 2020 legislation would remain in place.

Milestones Under the 2002 DOE-USEC Agreement

The Company’s predecessor USEC Inc. and DOE signed an agreement dated June 17, 2002, as amended (the “2002 DOE-USEC Agreement”), pursuant to which the parties made long-term commitments directed at resolving issues related to the stability and security of the domestic uranium enrichment industry. The 2002 DOE-USEC Agreement requires Centrus to develop, demonstrate and deploy advanced enrichment technology in accordance with milestones, including the deployment of a commercial American Centrifuge Plant, and provides for remedies in the event of a failure to meet a milestone under certain circumstances, including terminating the 2002 DOE-USEC Agreement, revoking Centrus’ access to DOE’s centrifuge technology that is required for the success of the Company’s ongoing work with the American Centrifuge technology, requiring Centrus to transfer certain rights in the American Centrifuge technology and facilities to DOE, and requiring Centrus to reimburse DOE for certain costs associated with the American Centrifuge technology. The 2002 DOE-USEC Agreement provides that if a delaying event beyond the control and without the fault or negligence of Centrus occurs that could affect Centrus’ ability to meet the American Centrifuge Plant milestone under the 2002 DOE-USEC Agreement, DOE and the Company will jointly meet to discuss in good faith possible adjustments to the milestones as appropriate to accommodate the delaying event. In 2014, the 2002 DOE-USEC Agreement and other agreements between the Company and DOE were assumed by Centrus subject to an express reservation of all rights, remedies and defenses by DOE and the Company under those agreements. DOE and the Company have agreed that all rights, remedies and defenses of the parties with respect to any missed milestones and all other matters under the 2002 DOE-USEC Agreement continue to be preserved, and that the time limits for each party to respond to any missed milestones continue to be tolled.

Legal Matters

From time to time, the Company is involved in various pending legal proceedings, including the pending legal proceedings described below.

In 1993, the United States Enrichment Corporation, at that time a wholly owned government corporation (“USEC-Government”), entered into a lease for the Paducah and Portsmouth Gaseous Diffusion Plants (collectively, the “GDPs”) with the DOE. As part of that lease, DOE and USEC-Government also entered into a memorandum of understanding (“Power MOU”) regarding power purchase agreements between DOE and the providers of power to the GDPs. Under the Power MOU, DOE and USEC-Government agreed upon the allocation of rights and liabilities under the power purchase agreements. In 1998, USEC-Government was privatized and became the United States Enrichment Corporation, now a principal subsidiary of the Company (“Enrichment Corp.”). Pursuant to legislation authorizing the privatization, the lease for the GDPs, which included the Power MOU as an Appendix, was transferred to Enrichment Corp., and Enrichment Corp. was given the right to purchase power from DOE. The Paducah Gaseous Diffusion Plant (“Paducah GDP”) was shut down in 2013 and deleased by Enrichment Corp. in 2014. On August 4, 2021, DOE informally informed Enrichment Corp. that the Joppa power plant, which had supplied power to the Paducah GDP, was planned to be decontaminated and decommissioned (“D&D”). According to DOE, the power purchase agreement with Electric Energy Inc. (“EEI”) requires DOE to pay for a portion of the D&D costs of the Joppa power plant and DOE has asserted that a portion of the DOE liability is the responsibility of Enrichment Corp. under the Power MOU in the amount of approximately $9.6 million. The Company is assessing DOE’s assertions including whether all or a portion of any such potential liability had been previously settled. The Company has not formed an opinion on the merits nor is it able to estimate the potential liability, if any, and no expense or liability has been accrued.

On May 26, 2019, the Company, Enrichment Corp., and six other DOE contractors who have operated facilities at the Portsmouth Gaseous Diffusion Plant in Piketon, Ohio ( “Portsmouth GDP”) (including, in the case of the Company, the American Centrifuge Plant site located on the premises) were named as defendants in a class action complaint filed by Ursula McGlone, Jason McGlone, Julia Dunham, and K.D. and C.D., minor children by and through their parent and natural guardian Julia Dunham (collectively, the “McGlone Plaintiffs”) in the U.S. District Court in the Southern District of Ohio, Eastern Division. The complaint seeks damages for alleged off-site contamination allegedly resulting from activities on the Portsmouth GDP site. The McGlone Plaintiffs are seeking

to represent a class of (i) all current or former residents within a seven-mile radius of the Portsmouth GDP site and (ii) all students and their parents at the Zahn’s Corner Middle School from 1993-present. The complaint was amended on December 10, 2019 and on January 10, 2020 to add additional plaintiffs and new claims. On July 31, 2020, the court granted in part and denied in part the defendants’ motion to dismiss the case. The court dismissed ten of the fifteen claims and allowed the remaining claims to proceed to the next stage of the litigation process. On August 18, 2020, the McGlone Plaintiffs filed a motion for leave to file a third amended complaint and notice of dismissal of three of the individual plaintiffs. On March 18, 2021, the McGlone Plaintiffs filed a motion for leave to file a fourth amended complaint to add new plaintiffs and allegations. On March 19, 2021, the court granted the McGlone Plaintiffs’ motion for leave to amend the complaint to include Price-Anderson Nuclear Industries Indemnity Act (“Price-Anderson Act”) and eight other state law claims. On May 24, 2021, the Company, Enrichment Corp., and the other defendants filed their motion to dismiss the complaint. On March 31, 2022, the court granted our motion in part by dismissing claims brought on behalf of the minor children but allowed the other claims to proceed. As such, the discovery stage of litigation is continuing. On April 28, 2022, the Company, Enrichment Corp., and the other defendants filed their answer to the fourth amended complaint. The Company believes that its operations at the Portsmouth GDP site were fully in compliance with the Nuclear Regulatory Commission’s regulations. Further, the Company and Enrichment Corp. believe that any such liability should be indemnified under the Price-Anderson Act. The Company and Enrichment Corp. have provided notifications to DOE required to invoke indemnification under the Price-Anderson Act and other contractual provisions.

On June 8, 2022, the Company, Enrichment Corp., and six other DOE contractors who operated facilities at the Portsmouth GDP were named as defendants in a complaint filed by Brad Allen Lykins, as administrator of the estate of Braden Aaron Lee Lykins in the U.S. District Court in the Southern District of Ohio, Eastern Division (“Lykins Complaint”). In March 2021, Brayden Lykins, who was thirteen years old, passed away from leukemia. The complaint alleges that the defendants released radiation into the environment in violation of the Price-Anderson Act causing Lykins’ death and seeks monetary damages. On August 30, 2022, the Company and Enrichment Corp. and the other defendants filed their answer to the Lykins Compliant. The Company and Enrichment Corp. believe that their operations at the Portsmouth GDP site were fully in compliance with the Nuclear Regulatory Commission’s regulations. Further, the Company and Enrichment Corp. believe that any such liability should be indemnified under the Price-Anderson Act. The Company and Enrichment Corp. have provided notifications to DOE required to invoke indemnification under the Price-Anderson Act and other contractual provisions.

Centrus is subject to various legal proceedings and claims, either asserted or unasserted, which arise in the ordinary course of business. While the outcome of these claims cannot be predicted with certainty, other than the above, Centrus does not believe that the outcome of any of these legal matters, individually and in the aggregate, will have a material adverse effect on its cash flows, results of operations, or consolidated financial condition.
