Basis of Presentation and Principles of Consolidation

The unaudited Consolidated Financial Statements of Centrus (the “Company”), which include the accounts of the Company, its principal subsidiary, Enrichment Corp., and its other subsidiaries, as of March 31, 2024, and for the three months ended March 31, 2024, and 2023, have been prepared pursuant to the rules and regulations of the SEC. The unaudited Consolidated Balance Sheet as of December 31, 2023, was derived from audited Consolidated Financial Statements, but does not include all disclosures required by U.S. 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 U.S. 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 months ended March 31, 2024 and 2023, are insignificant.

Operating results for the three months ended March 31, 2024, are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. The unaudited Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements included in the Annual Report on Form 10-K for the year ended December 31, 2023.

There has not been a material change to the Company’s accounting policies since that report.

Accounting Standards Effective in Future Periods

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

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

2. REVENUE AND CONTRACTS WITH CUSTOMERS

Disaggregation of Revenue

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

	Three Months Ended March 31,
	2024		2023
United States	$	23.6	$	58.7
Foreign	—		0.1
Revenue - SWU and uranium	$	23.6	$	58.8

Refer to Note 12, Segment Information, of this Quarterly Report on Form 10-Q for disaggregation of revenue by segment. Revenue for the LEU Segment is derived from the sales of the SWU component of LEU, from sales of both the SWU and uranium components, and from sales of UF6 and U3O8, to electric utility customers and other nuclear fuel related companies. Technical Solutions’ revenue is derived from services provided to the U.S. government and its contractors. SWU and uranium revenue is recognized when the customer obtains control of the SWU or uranium and Technical Solutions’ revenue is generally recognized over time based on direct costs incurred or the right to invoice method (in situations where the value transferred matches the Company’s billing rights) as the customer receives and consumes the benefits.

Accounts Receivable

	March 31, 2024		December 31, 2023
	(in millions)
Accounts receivable:
Billed	$	9.9	$	40.2
Unbilled *	10.0		9.2
Accounts receivable	$	19.9	$	49.4
* 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 due to timing of invoice processing or pending the compilation of supporting documentation.

Contract Liabilities

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

	March 31,   2024		December 31,   2023		Year-To-Date Change
Deferred revenue - current	$	252.8	$	252.4	$	0.4
Advances from customers - current	$	30.2	$	30.2	$	—
Advances from customers - noncurrent	$	32.8	$	32.8	$	—

Previously deferred sales and advances from customers recognized in revenue totaled $0 in both the three months ended March 31, 2024 and 2023.

LEU Segment

The SWU component of LEU typically is sold under contracts with deliveries over several years. The Company’s agreements for natural uranium hexafluoride and uranium concentrate sales generally are shorter-term, fixed-commitment contracts. Most of the Company’s customer contracts provide for fixed purchases of SWU during a given year. Depending on the terms of specific contracts, the customer may be able to increase or decrease the quantity delivered within an agreed range.

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.

In 2019, the Company entered into a cost-share contract with the DOE, the HALEU Demonstration Contract, to deploy a cascade of centrifuges to demonstrate production of HALEU for advanced reactors. The DOE agreed to reimburse the Company for 80% of its costs incurred in performing the contract. The DOE has funded the contract up to $173.0 million with a period of performance that ended November 30, 2022. The Company recorded revenue up to the funded amount of $173.0 million and received aggregate cash payments under the HALEU Demonstration Contract of $171.2 million through March 31, 2024. The Company is currently performing closeout activities on the HALEU Demonstration Contract.

The DOE elected to move the operational portion of the HALEU Demonstration Contract to a subsequent, competitively awarded contract and, on November 10, 2022, after a competitive solicitation, the DOE awarded the HALEU Operation Contract to the Company, and work began on December 1, 2022. The base contract value is approximately $150 million with two phases through 2024. Phase 1 included an approximately $30 million cost-share contribution from Centrus matched by approximately $30 million from the DOE to complete construction of the cascade, begin operations and produce the initial 20 kilograms of HALEU UF6 by no later than December 31, 2023. On October 11, 2023, the Company announced that it began enrichment operations in Piketon, Ohio. On November 7, 2023, the Company announced that it made its first delivery of HALEU to the DOE, completing Phase 1 by successfully demonstrating its HALEU production process.

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

Under the HALEU Operation Contract, DOE is obligated to provide the 5B Cylinders necessary to collect the output of the cascade, but supply chain challenges have created difficulties for DOE in securing enough 5B Cylinders for the entire production year. Using the 5B Cylinders currently made available by the DOE, Centrus has now achieved cumulative deliveries to the DOE of approximately 135 kilograms of HALEU UF6. Centrus’ delivery of the 900 kilograms of HALEU UF6, which it no longer can achieve by November 2024, was conditioned on the DOE’s ability to provide the 5B Cylinders on a timeline that allows for continuous production throughout Phase 2 of the contract. During time periods when 5B Cylinders are insufficient, the Company will be able to continue operations of the cascade, but will not be able to produce HALEU. The 9% target fee for Phase 2 of the contract was estimated to be $7.5 million based on the estimated costs for the contract and is subject to a contract minimum fee of $6.9 million.

15

To support the DOE in mitigating the risk of further delays in delivery of 5B Cylinders, the Company received technical direction and a contract modification from the DOE to procure compliant 5B Cylinders and components. The contractual obligation to furnish compliant 5B Cylinders under the HALEU Operation Contract continues to rest with the DOE. The Company is also performing additional work on infrastructure and facility repairs under DOE’s technical direction. On September 28, 2023, the DOE modified the HALEU Operation Contract to incorporate additional scope, not subject to cost-share reimbursement, for infrastructure and facility repairs, and costs associated with 5B Cylinder refurbishment, for an estimated additional contract value of $5.8 million. The DOE is currently obligated for costs up to approximately $5.8 million for the additional scope under the HALEU Operation Contract.

Costs under the HALEU Operation 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. When estimates of program costs to be incurred for an integrated, construction-type contract exceed estimates of total revenue to be earned, a provision for the remaining loss on the contract is recorded to Cost of Sales in the period the loss is determined. The Company’s corporate costs supporting the program are recognized as expense as incurred over the duration of the contract term. The Company recorded an accrued loss of $21.3 million related to anticipated cost-share reimbursement under the HALEU Operation Contract in Cost of Sales in December 2022. The accrued loss on the contract was adjusted over the contract term based on actual results and remaining program cost projections. At both March 31, 2024 and December 31, 2023, the remaining accrued contract loss balance was $0. The impact to Cost of Sales in the three months ended March 31, 2024 and 2023 was $0 and $5.5 million, respectively, for previously accrued contract losses attributable to work performed in those periods. The HALEU Operation Contract is funded incrementally, and the DOE currently is obligated for costs up to approximately $73.9 million of the $125.9 million estimated transaction price for Phase 1, Phase 2, and additional scope work. The Company has received aggregate cash payments under the HALEU Operation Contract of $55.2 million through March 31, 2024.

The Company does not have a contractual obligation to perform work in excess of the funding provided by the 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.

Remaining Performance Obligations

The Company’s remaining performance obligations represent the aggregate amount of total contract transaction price that is unsatisfied or partially unsatisfied. Performance obligations are recognized as revenue in future periods as work is performed or deliveries of SWU and uranium are made. The Company’s total remaining performance obligations were $1.0 billion as of both March 31, 2024 and December 31, 2023.

The remaining performance obligations in the LEU segment primarily related to medium and long-term contracts with fixed commitments, were approximately $1.0 billion for each of March 31, 2024 and December 31, 2023, and extend to 2030. The remaining performance obligations represent the estimated aggregate dollar amount of revenue for future SWU and uranium deliveries and includes approximately $315 million of Deferred Revenue and Advances from Customers at both March 31, 2024 and December 31, 2023. The remaining performance obligations are partially based on customer estimates of the timing and size of their fuel requirements and other assumptions that are subject to change. The remaining performance obligations include estimates of selling prices, which may be subject to change. 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.

16

The remaining performance obligations in the Technical Solutions segment were approximately $58 million and $77 million, as of March 31, 2024 and December 31, 2023, respectively, and extend to 2026. The remaining performance obligations in Technical Solutions include both funded (services for which funding has been both authorized and appropriated by the customer) and unfunded (services for which funding has not been appropriated) amounts. The Company does not include unexercised options or potential services under indefinite-delivery, indefinite-quantity agreements in its remaining performance obligations. If any of the Company’s contracts were to be terminated, its remaining performance obligations would be reduced by the expected value of the cancelled performance obligations of such contracts.

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):

	March 31, 2024		December 31, 2023
Cash and cash equivalents	$	209.3	$	201.2
Deposits for financial assurance - current (a)	18.9		0.2
Deposits for financial assurance - noncurrent	13.7		32.4
Total cash, cash equivalents and restricted cash	$	241.9	$	233.8

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

The Company has $4.9 million and $6.8 million denominated in euros as of March 31, 2024 and December 31, 2023, respectively, and recorded $0.1 million and $0 in transaction losses in the three months ended March 31, 2024 and March 31, 2023, respectively.

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

	March 31, 2024				December 31, 2023
	Current		Long-Term		Current		Long-Term
Collateral for Inventory Loans	$	18.7	$	11.1	$	—	$	29.8

Other	0.2		0.1		0.2		0.1
Total deposits for financial assurance	$	18.9	$	13.7	$	0.2	$	32.4

In March, May, and October 2022, the Company entered into three inventory loans that each required a cash deposit into an escrow fund. See Note 4, Inventories, of this Quarterly Report on Form 10-Q. 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.

4. INVENTORIES

Centrus holds uranium at licensed locations (e.g., fabricators) in the form of natural uranium hexafluoride and as the uranium component of LEU in transit to meet book transfer requests by customers and suppliers. Centrus also holds SWU as the SWU component of LEU at licensed locations or in transit 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):

	March 31, 2024						December 31, 2023
	Current Assets		Current Liabilities (a)		Inventories, Net		Current Assets		Current Liabilities (a)		Inventories, Net
Separative work units	$	20.7	$	—	$	20.7	$	21.9	$	—	$	21.9
Uranium	258.5		21.6		236.9		284.5		84.3		200.2
Total	$	279.2	$	21.6	$	257.6	$	306.4	$	84.3	$	222.1

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

Inventories are valued at the lower of cost or net realizable value.

The Company also may 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 2023, the Company borrowed UF6 which was recorded to inventory at a value of $22.5 million, based on the estimated fair market value of the inventory on the date of borrowing.

The Company performs quarterly revaluations of the Long-Term Inventory Loans reflecting an updated projection of the timing and sources of inventory to be used for repayment. These revaluations were recorded to Cost of Sales and resulted in an increase to the related liability of $0.3 million and $2.1 million, for the three months ended March 31, 2024 and 2023, respectively.

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 LEU segment backlog is amortized as the backlog, existing at emergence, is reduced, 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):

	March 31, 2024						December 31, 2023
	Gross Carrying Amount		Accumulated Amortization		Net Amount		Gross Carrying Amount		Accumulated Amortization		Net Amount
Backlog	$	54.6	$	41.6	$	13.0	$	54.6	$	41.6	$	13.0
Customer relationships	68.9		43.6		25.3		68.9		42.5		26.4

8.25% Notes:	Feb. 2027
Principal		$	—	$	74.3	$	—	$	74.3
Interest		6.1		12.2		6.1		15.3
Total		$	6.1	$	86.5	$	6.1	$	89.6

Interest on the Company’s 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 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 March 31, 2024 and December 31, 2023, $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 the Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

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):

	March 31, 2024								December 31, 2023
	Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3		Total

Liabilities:
Deferred compensation obligation (a)	$	3.8	$	—	$	—	$	3.8	$	3.3	$	—	$	—	$	3.3

(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.

19

Other Financial Instruments

As of March 31, 2024, and December 31, 2023, 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):

	March 31, 2024					December 31, 2023

9. NET INCOME (LOSS) PER SHARE

Basic net income (loss) per share is calculated by dividing net income (loss) 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 common shares related to stock compensation awards including restricted stock, stock options, stock appreciation rights and notional stock units, and the Warrant. No dilutive effect is recognized in a period in which a net loss has occurred.

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

	Three Months Ended   March 31,
	2024		2023
Numerator (in millions):
Net income (loss)	$	(6.1)	$	7.2
Denominator (in thousands):
Average common shares outstanding - basic	15,906		14,841
Potentially dilutive shares related to stock compensation awards and warrant	—		400
Average common shares outstanding - diluted	15,906		15,241
Net income (loss) per share (in dollars):
Basic	$	(0.38)	$	0.49
Diluted	$	(0.38)	$	0.47
Common stock equivalents excluded from the diluted calculation because they would have been antidilutive (in thousands)	118		1

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, 2023. As a result of exercising this right to reschedule, the Company has 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 the Orano Supply Agreement with a French company, Orano Cycle, for the long-term supply of SWU contained in LEU. The Orano Supply Agreement subsequently was assigned by Orano Cycle to its affiliate, Orano CE. 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.

Milestones Under the 2002 DOE-USEC Agreement

The Company’s predecessor, USEC Inc., and DOE signed the 2002 DOE-USEC Agreement dated June 17, 2002, 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 milestones 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.

24

Legal Matters

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

In 1993, USEC-Government entered into a lease for the Paducah and Portsmouth GDPs with the DOE. As part of that lease, DOE and USEC-Government also entered into a Power 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 Enrichment Corp., now a principal subsidiary of the Company. 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 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 undergo D&D. According to DOE, the power purchase agreement with Electric Energy Inc. 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 of DOE’s claim nor is it able to estimate its potential liability, if any, for such claim 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 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 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 the Company’s 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 NRC’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.

25

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, Enrichment Corp., and the other defendants filed their answer to the Lykins Complaint. The Company and Enrichment Corp. believe that their operations at the Portsmouth GDP site were fully in compliance with the NRC’s regulations. Further, the Company and Enrichment Corp. believe that any such liability should be indemnified by DOE 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 March 8, 2023, the Company, Enrichment Corp., and six other DOE contractors that operated facilities at the Portsmouth GDP were named as defendants in a complaint filed by Christian Rose in the U.S. District Court in the Southern District of Ohio, Eastern Division (“Rose Complaint”). Christian Rose was diagnosed with cancer in June 2022. Although Mr. Rose is an adult, he attended the Zahn Corner Middle School, which was closed a few years ago due to contamination and is in the vicinity of the plant. The Rose Complaint alleges that the defendants released radiation into the environment in violation of the Price-Anderson Act causing death – even though the plaintiff is still alive – and seeks monetary damages in the nature of past and future medical expenses, pain and suffering and punitive damages, among others. On May 15, 2023, the Company, Enrichment Corp. and the other defendants filed their answers to the Rose Complaint. The Company and Enrichment Corp. believe that their operations at the Portsmouth GDP site were fully in compliance with the NRC’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 the DOE required to invoke indemnification under the Price-Anderson Act and other contractual provisions.

On November 27, 2023, 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 Joshua Shaw in the U.S. District Court in the Southern District of Ohio, Eastern Division (“Shaw Complaint”). Joshua Shaw was diagnosed with Acute Myeloid Leukemia (AML) in August 2008 and after going through chemotherapy continues to experience aftereffects of AML, including anxiety and fatigue. The Shaw Complaint alleges that the defendants released radiation into the environment exposing Mr. Shaw to radiation in violation of the Price-Anderson Act and causing Mr. Shaw’s AML and other injuries. Mr. Shaw seeks monetary damages in the nature of past and future medical expenses for treatment and care, pain and suffering and punitive damages, among others. The Company and Enrichment Corp. believe that their operations at the Portsmouth GDP site were fully in compliance with the NRC’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 the 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, 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 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) 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 currently provides most of the Company’s revenue and involves the sale of enriched uranium, the fissile component of nuclear fuel primarily to utilities that operate commercial nuclear power plants. The majority of these sales are for the enrichment component of LEU, which is measured in SWU. Centrus also sells natural uranium hexafluoride (the raw material needed to produce LEU) and occasionally sells uranium concentrates, uranium conversion, or LEU with the natural uranium hexafluoride 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.

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 period of price increases which reached $155 per SWU by December 31, 2023. As of March 31, 2024, spot prices are $166 per SWU. This represents an increase of 7% since the beginning of the year and 388% over the 2018 historic low. This surge in the SWU spot price beginning in 2022 has been driven by uncertainty created as a result of the war in Ukraine, coupled with growing interest in nuclear power as a source of reliable carbon-free energy.

When Russian supply is included, the uranium enrichment segment of the global nuclear fuel market is oversupplied. But without Russian supply, the global market for uranium enrichment would be undersupplied. Further, it is not clear that there are sufficient inventories of enriched uranium in the United States to compensate for a loss of Russian supply, absent new capacity that will take a number of years to deploy. A report issued by the International Atomic Energy Agency in 2023 reported that while U.S. utilities may have enough inventory to cover one reload of their reactors, “truly strategic physical stockpiles are almost non-existent.”1

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

Our Technical Solutions segment is committed 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 is also 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.

Under the 2019 HALEU Demonstration Contract, Centrus was engaged by the DOE to construct a cascade of 16 AC100M centrifuges in Piketon, Ohio to demonstrate HALEU production. The DOE has funded the contract up to $173.0 million with a period of performance that ended November 30, 2022. The Company is currently performing closeout activities on the HALEU Demonstration Contract. The DOE elected to change the scope of the HALEU Demonstration Contract and moved the operational portion of the contract to a new, competitively-awarded contract that would provide for operations beyond the term of the existing HALEU Demonstration Contract.

On November 10, 2022, after a competitive solicitation, the DOE notified Centrus that the Company had won the HALEU Operation Contract and work began on December 1, 2022. The base contract value is approximately $150 million with two phases through 2024. Phase 1 included an approximately $30 million cost-share contribution from Centrus matched by approximately $30 million from the DOE to complete construction of the cascade, begin operations and produce the initial 20 kilograms of HALEU UF6 by no later than December 31, 2023. On October 11, 2023, the Company announced that it began enrichment operations in Piketon, Ohio. On November 7, 2023, the Company announced that it made its first delivery of HALEU to the DOE, completing Phase 1 by successfully demonstrating its HALEU production process. During November 2023, the Company transitioned to Phase 2 of the HALEU Operation Contract.

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

29

Under the HALEU Operation Contract, DOE is contractually obligated to provide the 5B Cylinders necessary to collect the output of the cascade, but supply chain challenges have created difficulties for DOE in timely securing enough 5B Cylinders for the entire production year. To support the DOE in mitigating the risk of further delays in delivery of 5B Cylinders, the Company received technical direction and a contract modification from the DOE to procure compliant 5B Cylinders and components. The contractual obligation to furnish compliant 5B Cylinders under the HALEU Operation Contract continues to rest with the DOE. During periods where quantities of 5B Cylinders are insufficient, the Company will not be able to produce HALEU, but will be able to continue operations of the cascade and perform preventive maintenance and regulatory compliance type activities. Centrus anticipates that the delays in obtaining sufficient 5B Cylinders will be temporary, but no longer expects to achieve delivery of the 900 kilograms of HALEU UF6 anticipated for Phase 2 of the contract which extends to November 2024. Although inadequate for meeting the full delivery quantity target, the DOE has been successful in locating a small number of 5B Cylinders. Using the 5B Cylinders currently made available by the DOE, Centrus has now achieved cumulative deliveries to the DOE of approximately 135 kilograms of HALEU UF6. We anticipate additional 5B Cylinders will be available during the second quarter, which will allow the Company to continue producing HALEU. The target fee for Phase 2 of the contract was estimated to be $7.5 million based on the estimated costs for the contract and is subject to a contract minimum fee of $6.9 million. The Company is also performing additional work on infrastructure and facility repairs under DOE’s technical direction and subsequent contract modification.

The DOE continues to pursue the availability of HALEU for the ARDP and for the advanced reactor market in general. Following receipt of a $700 million congressional appropriation from the Inflation Reduction Act, on January 9, 2024 and November 28, 2023, the DOE issued RFPs for the production of HALEU and the deconversion of HALEU into different forms needed to fabricate fuels used by various advanced reactor developers. The Company has submitted proposals in response to each RFP, with the goal of expanding HALEU production capability at the Piketon facility, subject to availability of funding and/or off-take commitments. We understand that the DOE plans to award one or more indefinite delivery-indefinite quantity contracts to one or more successful bidders, after which one or more awardees would compete for individual task orders. The total contract ceiling for all task orders is $2.7 billion for enrichment and $800 million for deconversion, subject to further appropriations.

The war in Ukraine has contributed to a significant increase in market prices for enrichment and (along with proposals to limit imports of LEU from Russia) 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 off-take commitments.

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

30

While the monthly price indicators have increased for several years, the uranium enrichment segment of the nuclear fuel market remains oversupplied and faces uncertainty about future demand for nuclear power generation. However, without Russian supply, the global market would be undersupplied for uranium enrichment. Changes in the competitive landscape affect pricing trends, change customer spending patterns, and create uncertainty. To address these changes, we have taken steps to adjust our cost structure; we may seek further adjustments to our cost structure and operations and evaluate opportunities to grow our business organically or through acquisitions and other strategic transactions.

We are also actively considering and expect to consider potential strategic transactions from time to time, 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. For further discussion, refer to Liquidity and Capital Resources 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 nuclear power or to increase the share of nuclear power in their nations has created optimism in the market. Part of the momentum has resulted from efforts to lower greenhouse gas emissions to combat climate change and improve health and safety.

According to the WNA, as of March 2024, there were 60 reactors under construction worldwide, approximately one-half of which are in China. The United States, with over 90 operating reactors, remains the world’s largest market for nuclear fuel. The nuclear industry in the United States, Japan, and Europe faces headwinds as well as opportunities. In the United States, the industry has been under pressure from the expansion of subsidized renewable energy as well as relatively low-cost natural gas resources in recent years, although natural gas prices in the U.S. electricity sector tripled between 2020 and 2022 according to data from the U.S. Energy Information Administration (“EIA”). Nine 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, construction was recently completed and commercial operations began in the second quarter of 2024 on one large reactor. The DOE recently released a report outlining a pathway to deployment of approximately 200 gigawatts of additional capacity by 2050 which would triple the nuclear energy capacity in the United States.

31

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

As a consequence of the March 2011 earthquake and tsunami in Japan, over 60 reactors in Japan and Germany were taken offline, and other countries curtailed or slowed their construction of new reactors or accelerated the retirement of existing plants. Eleven reactors in Japan have restarted, and an additional 16 reactors are in the process of restart approval. Due to the war in Ukraine, the EU is encouraging its member countries to reconsider the planned early retirement of existing plants in order to reduce reliance on Russian gas imports.

32

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

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

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

The war in Ukraine has escalated tensions between Russia and the international community. As a result, the United States and other countries have imposed, including in the United States through the imminent enactment of the “Prohibiting Russian Uranium Imports Act” discussed below, and may continue imposing, additional sanctions and export controls against certain Russian products, services, organizations and/or individuals. Such additional restrictions could affect our ability to purchase and re-sell Russian uranium enrichment, engage in transactions with TENEX, or implement the TENEX Supply Contract, which would 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. Due to restrictions imposed by Canada on the ability of Canadian persons and entities to provide ocean transportation services to Russia, a permit is required for our shipper, a Canadian company, to transport the LEU that we procure under the TENEX Supply Contract to the United States. A Canadian permit issued to our shipper was recently extended to March 2027, but for so long as the sanctions remain in place, the shipper will require further extensions beyond the current validity of the permit for continued shipments of LEU imports.

33

In response to the war in Ukraine, there have been proposals to ban imports of uranium products that could cut off or reduce our ability to import LEU in one or more years under the TENEX Supply Contract. In fact, in December 2023, the U.S. House of Representatives passed H.R. 1042, the “Prohibiting Russian Uranium Imports Act”, which was also passed by the U.S. Senate on April 30, 2024. This legislation bans imports of LEU from Russia into the U.S. beginning ninety (90) days after the date of enactment, subject to issuance of waivers by the DOE. The legislation is before the President for signature into law and its enactment is expected imminently. The U.S. ban on imports of Russian LEU without the grant of a timely waiver, would have a negative material impact on our business. Through 2027, well over one-half of the LEU that we expect to deliver to customers was sourced under the TENEX Supply Contract. While we have other sources of supply, they are not sufficient to replace the TENEX supply. Accordingly, upon enactment of the “Prohibiting Russian Uranium Imports Act”, we will apply for waivers from the Secretary of Energy and other applicable government agencies to allow us to request permission to continue supplying LEU to our customers. It is uncertain whether any waiver would be granted and, if granted, whether any waiver would be granted in a timely manner. In addition, there is draft legislation in Congress designed to impose sanctions on Rosatom which would prohibit transactions with TENEX, a subsidiary of Rosatom. We do not know what actions TENEX might take in response to the legislation when enacted but, if TENEX refuses to make future deliveries under the TENEX Supply Contract, our delivery obligations to our customers would be negatively impacted, including a potential material adverse effect on the Company.

In addition to limitations targeted specifically at imports of LEU, the expanding sanctions imposed by the United States and foreign governments on the mechanisms used to make payments to Russia and to obtain services including transportation and other services have increased the risk that implementation of the TENEX Supply Contract may be disrupted in the future. If the U.S. government were to prohibit companies and individuals from engaging in transactions with Rosatom and its subsidiaries, including TENEX, the Company and its suppliers could not implement the TENEX Supply Contract absent a license or other authorization from the sanctioning government.

Given all the foregoing, we continue to monitor the situation closely in order to address the potential impact of any new sanctions on the Company and possible mitigation thereof.

For further discussion of these risks and uncertainties, refer to Part I, Item 1A, Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2023.

Operating Results

Our revenues, operating results, and cash flows can fluctuate significantly from quarter to quarter and year to year. Our LEU segment backlog consists primarily of long-term, fixed commitment contracts, and we have visibility on a significant portion of our revenue for 2024-2027.

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

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 that restrict with whom we may transact or affect the importation, sales or purchases of SWU or uranium or goods or services required for the sale, purchase, transportation or delivery of such SWU or uranium;

•Our ability to obtain a waiver to allow us to import LEU from Russia so that we may continue supplying LEU to our customers upon the likely enactment of the “Prohibiting Russian Uranium Imports Act”;

34

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

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

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

•Costs of and future funding and demand for HALEU;

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

•The outcome of legal proceedings and other contingencies;

•Potential use of cash for strategic or financial initiatives;

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

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

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

For further discussion of these uncertainties, refer to Part I, Item 1A, Risk Factors, in our Annual Report on Form 10-K for the year ended December 31, 2023.

Backlog

The Company’s backlog is $2.0 billion as of both March 31, 2024 and December 31, 2023 and extends to 2033. Backlog is recognized as revenue in future periods as work is performed or deliveries of SWU and uranium are made.

Our backlog in the LEU segment extends to 2030. As of March 31, 2024 and December 31, 2023, our backlog was approximately $1.0 billion. The backlog is the estimated aggregate dollar amount of revenue for future SWU and uranium deliveries primarily under medium and long-term contracts with fixed commitments, and includes approximately $0.3 billion of deferred revenue and advances from customers as of March 31, 2024, whereby customers have made advance payments to be applied against future deliveries. No orders in our backlog are considered at risk related to customer operations. However, these medium and long-term contracts are subject to significant risks and uncertainties, including existing import laws and restrictions such as the RSA, which limits imports of Russian uranium products into the United States and applies to our sales using material procured under the TENEX Supply Contract, as well as the potential for additional sanctions and other restrictions affecting the Company or its suppliers, in response to the evolving situation regarding the war in Ukraine.

Our backlog in the Technical Solutions segment extends to 2033. As of both March 31, 2024 and December 31, 2023, our backlog was approximately $1.0 billion. Our backlog includes both funded amounts (services for which funding has been both authorized and appropriated by the customer), unfunded amounts (services for which funding has not been appropriated), and unexercised options. If any of our contracts were to be terminated, our remaining backlog would be reduced by the expected value of the cancelled contracts.

35

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 hexafluoride, uranium concentrates or uranium conversion, and

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

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

SWU and Uranium Sales

Revenue from our LEU segment accounted for approximately 54% of our total revenue for the three months ended March 31, 2024. The majority of our customers are domestic and international utilities that operate nuclear power plants, with international sales constituting approximately 34% of revenue from our LEU segment since 2022. 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 hexafluoride components of LEU to utilities or where we sell natural uranium hexafluoride to utilities and other nuclear fuel related companies are generally shorter-term, fixed-commitment contracts. Individual customer orders for the SWU component of LEU fulfilled in the three months ended March 31, 2024 averaged approximately $5.9 million per order. As a result, a relatively small shift in the timing of customer orders for LEU may cause significant variability in our operating results year over year.

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, of this Quarterly Report on Form 10-Q of 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 hexafluoride. 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 war in Ukraine has driven SWU and uranium hexafluoride prices sharply higher. Since our backlog 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 backlog have prices that are above current market prices.

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

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 in obtaining new contracts in a competitive bidding process depending upon the weakness or strength of the U.S. dollar. Under a customer contract that commenced deliveries in 2023, payments are denominated in euros, and subject to exchange rate risk. Costs of our primary competitors are denominated in other currencies. Our contracts with suppliers are primarily denominated in U.S. dollars. We have a SWU supply agreement, that commenced in 2023, with prices payable in a combination of U.S. dollars and euros, but with a contract-defined exchange rate.

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

37

Cost of sales for SWU and uranium is based on the amount of SWU and uranium hexafluoride sold and delivered during the period and unit inventory costs. Unit inventory costs are determined using the average cost method. Changes in purchase costs have an effect on inventory costs and cost of sales. Cost of sales includes costs for inventory management at off-site licensed locations and 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 Operation Contract. Subject to the availability of sufficient funding and off-take commitments, our goal is to expand our uranium enrichment capacity to meet the full range of U.S. government and commercial requirements for enriched uranium. With our government and private sector customers, we seek to leverage our domestic enrichment experience as well as our 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-related components 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.

Revenue

Revenue from the LEU segment was $23.6 million and $58.8 million for the three months ended March 31, 2024 and 2023, respectively, a decrease of $35.2 million (or 60%), SWU revenue decreased by $35.2 million as a result of a 53% decrease in the volume of SWU sold and a 14% decrease in the average price of SWU sold.

Revenue from the Technical Solutions segment was $20.1 million and $8.1 million for the three months ended March 31, 2024 and 2023, respectively, an increase of $12.0 million (or 148%). Revenue generated by the HALEU Operation Contract increased by $12.0 million due to the transition from Phase 1 to Phase 2 in late 2023.

Cost of Sales

Cost of sales for the LEU segment was $23.1 million and $34.9 million for the three months ended March 31, 2024 and 2023, respectively, a decrease of $11.8 million (or 34%). SWU costs decreased by $12.3 million as a result of a 53% decrease in the volume of SWU sold, partially offset by a 38% increase in the average unit cost of SWU sold. Cost of sales for the three months ended March 31, 2024 and 2023, respectively, included $0.3 million and $2.1 million for the revaluation of inventory loans.

39

Cost of sales for the Technical Solutions segment was $16.3 million and $9.0 million for the three months ended March 31, 2024 and 2023, respectively, an increase of $7.3 million (or 81%). Costs incurred for the HALEU Operation Contract increased by $7.3 million due to the transition from Phase 1 to Phase 2 in late 2023. For details on HALEU Operation Contract accounting, refer to Technical Solutions Segment above.

Gross Profit (Loss)

Gross profit for the LEU segment was $0.5 million and $23.9 million for the three months ended March 31, 2024 and 2023, respectively, a decrease of $23.4 million (or 98%). The decrease for the three months ended March 31, 2024 was due primarily to the specific contract and pricing mix of SWU contracts and the timing of their deliveries quarter over quarter. This was reflected by a decrease in the volume of SWU sold and a decrease in the average profit margin per SWU.

Gross profit (loss) for the Technical Solutions segment was $3.8 million and ($0.9) million for the three months ended March 31, 2024 and 2023, respectively, an increase of $4.7 million (or 522%). The increase was primarily attributable to the transition from Phase 1 to Phase 2 of the HALEU Operation Contract.

Advanced Technology Costs

Advanced technology costs were $5.7 million and $3.4 million for the three months ended March 31, 2024 and 2023, respectively, an increase of $2.3 million (or 68%). 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.

40

Selling, General and Administrative

Selling, general and administrative costs were $8.1 million and $10.3 million for the three months ended March 31, 2024 and 2023, respectively, a decrease of $2.2 million (or 21%). This decrease was due primarily to a decrease in employee-related expenses, including equity related compensation, and a decrease in consulting costs.

Income Tax Expense (Benefit)

Income tax expense (benefit) was ($2.3) million and $2.4 million for the three months ended March 31, 2024 and 2023, respectively, a change of $4.7 million (or 196%). Income tax expense (benefit) for both periods resulted from applying the annual effective tax rate to the quarterly income from continuing operations adjusted for discrete items. For more information about the valuation allowance, see Note 14, Income Taxes, in our Consolidated Financial Statements on our Annual Report on Form 10-K for the year ended December 31, 2023.

Net Income (Loss) and Comprehensive Income (Loss)

Net income (loss) was ($6.1) million and $7.2 million for the three months ended March 31, 2024 and 2023, respectively, a change of $13.3 million (or 185%). The decrease of $13.3 million was primarily attributable to a $23.4 million decrease in gross profit from the LEU segment and a $2.3 million increase in advanced technology costs, partially offset by a $4.7 million increase in gross profit from the Technical Solutions segment and a $4.7 million decrease in income tax expense (benefit).

41

Liquidity and Capital Resources

As of March 31, 2024, the Company had a consolidated cash and cash equivalents balance of $209.3 million. In addition, there was $29.8 million of restricted cash related to three inventory loans, which required a cash deposit into an escrow fund. See Note 3, Cash, Cash Equivalents, and Restricted Cash of the Consolidated Financial Statements. The Company anticipates 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, sanctions and other conditions, the impact of enactment of the “Prohibiting Russian Uranium Imports Act” and our ability to obtain a waiver thereunder, should the legislation be enacted, 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.

The Company believes its LEU segment backlog 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.

On November 10, 2022, the Company was awarded the HALEU Operation Contract. The HALEU Operation Contract provides for a 50/50 cost-share contract for Phase 1 of the base contract to complete the cascade, begin operations and complete the initial, small quantity demonstration HALEU. Phase 2 includes continued operations and maintenance on a cost-plus-incentive-fee basis. Finally, the HALEU Operation Contract includes options for the government to unilaterally extend performance for up to an additional nine years comprised of three options of three years each, also on a cost-plus-incentive-fee basis. The Company also is performing additional work on infrastructure and facility repairs and costs associated with 5B Cylinder refurbishment under the DOE’s technical direction. The Company’s goal is to modularly scale up the facility as demand for HALEU grows in the commercial and government sectors, subject to the availability of funding and/or contracts to purchase the output of the plant.

Although the Company believes demand for HALEU will emerge over the next several years, there are no guarantees about whether or when government or commercial demand for HALEU will materialize, and there are a number of technical, regulatory, and economic hurdles that must be overcome for these fuels and the reactors that will use these fuels to come to market. 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, 2023.

If funding by the U.S. government of gas centrifuge technology is reduced or discontinued, or we are not awarded a future DOE contract to continue to operate the cascade or expand it, 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 $5.5 million are anticipated over the next 12 months.

We are also actively considering and expect to consider potential strategic transactions from time to time, which at any given time may be in various stages of discussion, diligence, or negotiation. These could involve, without limitation, acquisitions and/or dispositions of businesses or assets, joint ventures or investments in businesses, products or technologies, or changes to our capital structure. In connection with any such transaction, we would seek to satisfy these needs through a combination of working capital, cash generated from operations, or additional debt or equity financing.

Increase in cash, cash equivalents and restricted cash	$	8.1	$	8.9

Operating Activities

For the three months ended March 31, 2024, net cash provided by operating activities was $5.3 million. The net increase was primarily due to approximately $81.0 million in cash collected from customers, investment income, and reimbursements for postretirement health and life benefits paid by the Company. These cash inflows were partially offset by approximately $76.0 million of disbursements for operations, of which approximately $52.0 million relates to payments for LEU inventory deliveries and cash outflows for the Technical Solutions segment, with the remaining disbursements being for corporate administration, benefits claims, and advanced technology costs.

In the three months ended March 31, 2023, net cash used in operating activities was $9.7 million. The net decrease was primarily due to $89.1 million of disbursements for operations, of which $59.4 million relates to payments for LEU inventory deliveries and cash outflows for the Technical Solutions segment, with the remaining disbursements being for corporate administration, benefits claims, and advanced technology costs. These cash outflows were partially offset by approximately $74.8 million in cash collected from customers.

Investing Activities

Capital expenditures were $1.5 million and $0.3 million for the three months ended March 31, 2024 and 2023, respectively.

Financing Activities

For the three months ended March 31, 2024 and 2023, cash of $7.1 million and $22.0 million, respectively, was provided from the net proceeds related to the issuance of 176,628 and 722,568 shares, respectively, of Class A Common Stock under an ATM offering. For both the three months ended March 31, 2024 and 2023, payments of $3.1 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 maturing in February 2027.

Other current assets and liabilities, net	(114.0)		(87.3)
Working capital	$	201.3	$	214.3

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 because we believe these uses of working capital are 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.

Centrus maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed by Centrus in reports it files or submits under the Exchange Act is recorded, processed, summarized and reported in the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to management, including the Chief Executive Officer and the Chief Financial Officer, as appropriate to allow for timely decisions regarding required disclosures.

As of March 31, 2024, the end of the period covered by this Quarterly Report on Form 10-Q, our management performed an evaluation, under the supervision and with the participation of the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act). Based on this evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended March 31, 2024, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

BASIS OF PRESENTATION

Basis of Presentation and Principles of Consolidation

The unaudited Consolidated Financial Statements of Centrus (the “Company”), which include the accounts of the Company, its principal subsidiary, Enrichment Corp., and its other subsidiaries, as of March 31, 2024, and for the three months ended March 31, 2024, and 2023, have been prepared pursuant to the rules and regulations of the SEC. The unaudited Consolidated Balance Sheet as of December 31, 2023, was derived from audited Consolidated Financial Statements, but does not include all disclosures required by U.S. 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 U.S. 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 months ended March 31, 2024 and 2023, are insignificant.

Operating results for the three months ended March 31, 2024, are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. The unaudited Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements included in the Annual Report on Form 10-K for the year ended December 31, 2023.

Significant Accounting Policies

The accounting policies of the Company are set forth in Note 1, Summary of Significant Accounting Policies, of the Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. There has not been a material change to the Company’s accounting policies since that report.

Revenue from Contract with Customer

REVENUE AND CONTRACTS WITH CUSTOMERS

Disaggregation of Revenue

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

	Three Months Ended March 31,
	2024		2023
United States	$	23.6	$	58.7
Foreign	—		0.1
Revenue - SWU and uranium	$	23.6	$	58.8

Refer to Note 12, Segment Information, of this Quarterly Report on Form 10-Q for disaggregation of revenue by segment. Revenue for the LEU Segment is derived from the sales of the SWU component of LEU, from sales of both the SWU and uranium components, and from sales of UF6 and U3O8, to electric utility customers and other nuclear fuel related companies. Technical Solutions’ revenue is derived from services provided to the U.S. government and its contractors. SWU and uranium revenue is recognized when the customer obtains control of the SWU or uranium and Technical Solutions’ revenue is generally recognized over time based on direct costs incurred or the right to invoice method (in situations where the value transferred matches the Company’s billing rights) as the customer receives and consumes the benefits.

Accounts Receivable

	March 31, 2024		December 31, 2023
	(in millions)
Accounts receivable:
Billed	$	9.9	$	40.2
Unbilled *	10.0		9.2
Accounts receivable	$	19.9	$	49.4
* 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 due to timing of invoice processing or pending the compilation of supporting documentation.

Contract Liabilities

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

	March 31,   2024		December 31,   2023		Year-To-Date Change
Deferred revenue - current	$	252.8	$	252.4	$	0.4
Advances from customers - current	$	30.2	$	30.2	$	—
Advances from customers - noncurrent	$	32.8	$	32.8	$	—

Previously deferred sales and advances from customers recognized in revenue totaled $0 in both the three months ended March 31, 2024 and 2023.

LEU Segment

The SWU component of LEU typically is sold under contracts with deliveries over several years. The Company’s agreements for natural uranium hexafluoride and uranium concentrate sales generally are shorter-term, fixed-commitment contracts. Most of the Company’s customer contracts provide for fixed purchases of SWU during a given year. Depending on the terms of specific contracts, the customer may be able to increase or decrease the quantity delivered within an agreed range.

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.

In 2019, the Company entered into a cost-share contract with the DOE, the HALEU Demonstration Contract, to deploy a cascade of centrifuges to demonstrate production of HALEU for advanced reactors. The DOE agreed to reimburse the Company for 80% of its costs incurred in performing the contract. The DOE has funded the contract up to $173.0 million with a period of performance that ended November 30, 2022. The Company recorded revenue up to the funded amount of $173.0 million and received aggregate cash payments under the HALEU Demonstration Contract of $171.2 million through March 31, 2024. The Company is currently performing closeout activities on the HALEU Demonstration Contract.

The DOE elected to move the operational portion of the HALEU Demonstration Contract to a subsequent, competitively awarded contract and, on November 10, 2022, after a competitive solicitation, the DOE awarded the HALEU Operation Contract to the Company, and work began on December 1, 2022. The base contract value is approximately $150 million with two phases through 2024. Phase 1 included an approximately $30 million cost-share contribution from Centrus matched by approximately $30 million from the DOE to complete construction of the cascade, begin operations and produce the initial 20 kilograms of HALEU UF6 by no later than December 31, 2023. On October 11, 2023, the Company announced that it began enrichment operations in Piketon, Ohio. On November 7, 2023, the Company announced that it made its first delivery of HALEU to the DOE, completing Phase 1 by successfully demonstrating its HALEU production process.

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

Under the HALEU Operation Contract, DOE is obligated to provide the 5B Cylinders necessary to collect the output of the cascade, but supply chain challenges have created difficulties for DOE in securing enough 5B Cylinders for the entire production year. Using the 5B Cylinders currently made available by the DOE, Centrus has now achieved cumulative deliveries to the DOE of approximately 135 kilograms of HALEU UF6. Centrus’ delivery of the 900 kilograms of HALEU UF6, which it no longer can achieve by November 2024, was conditioned on the DOE’s ability to provide the 5B Cylinders on a timeline that allows for continuous production throughout Phase 2 of the contract. During time periods when 5B Cylinders are insufficient, the Company will be able to continue operations of the cascade, but will not be able to produce HALEU. The 9% target fee for Phase 2 of the contract was estimated to be $7.5 million based on the estimated costs for the contract and is subject to a contract minimum fee of $6.9 million.

To support the DOE in mitigating the risk of further delays in delivery of 5B Cylinders, the Company received technical direction and a contract modification from the DOE to procure compliant 5B Cylinders and components. The contractual obligation to furnish compliant 5B Cylinders under the HALEU Operation Contract continues to rest with the DOE. The Company is also performing additional work on infrastructure and facility repairs under DOE’s technical direction. On September 28, 2023, the DOE modified the HALEU Operation Contract to incorporate additional scope, not subject to cost-share reimbursement, for infrastructure and facility repairs, and costs associated with 5B Cylinder refurbishment, for an estimated additional contract value of $5.8 million. The DOE is currently obligated for costs up to approximately $5.8 million for the additional scope under the HALEU Operation Contract.

Costs under the HALEU Operation 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. When estimates of program costs to be incurred for an integrated, construction-type contract exceed estimates of total revenue to be earned, a provision for the remaining loss on the contract is recorded to Cost of Sales in the period the loss is determined. The Company’s corporate costs supporting the program are recognized as expense as incurred over the duration of the contract term. The Company recorded an accrued loss of $21.3 million related to anticipated cost-share reimbursement under the HALEU Operation Contract in Cost of Sales in December 2022. The accrued loss on the contract was adjusted over the contract term based on actual results and remaining program cost projections. At both March 31, 2024 and December 31, 2023, the remaining accrued contract loss balance was $0. The impact to Cost of Sales in the three months ended March 31, 2024 and 2023 was $0 and $5.5 million, respectively, for previously accrued contract losses attributable to work performed in those periods. The HALEU Operation Contract is funded incrementally, and the DOE currently is obligated for costs up to approximately $73.9 million of the $125.9 million estimated transaction price for Phase 1, Phase 2, and additional scope work. The Company has received aggregate cash payments under the HALEU Operation Contract of $55.2 million through March 31, 2024.

The Company does not have a contractual obligation to perform work in excess of the funding provided by the 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.

Remaining Performance Obligations

The Company’s remaining performance obligations represent the aggregate amount of total contract transaction price that is unsatisfied or partially unsatisfied. Performance obligations are recognized as revenue in future periods as work is performed or deliveries of SWU and uranium are made. The Company’s total remaining performance obligations were $1.0 billion as of both March 31, 2024 and December 31, 2023.

The remaining performance obligations in the LEU segment primarily related to medium and long-term contracts with fixed commitments, were approximately $1.0 billion for each of March 31, 2024 and December 31, 2023, and extend to 2030. The remaining performance obligations represent the estimated aggregate dollar amount of revenue for future SWU and uranium deliveries and includes approximately $315 million of Deferred Revenue and Advances from Customers at both March 31, 2024 and December 31, 2023. The remaining performance obligations are partially based on customer estimates of the timing and size of their fuel requirements and other assumptions that are subject to change. The remaining performance obligations include estimates of selling prices, which may be subject to change. 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.

The remaining performance obligations in the Technical Solutions segment were approximately $58 million and $77 million, as of March 31, 2024 and December 31, 2023, respectively, and extend to 2026. The remaining performance obligations in Technical Solutions include both funded (services for which funding has been both authorized and appropriated by the customer) and unfunded (services for which funding has not been appropriated) amounts. The Company does not include unexercised options or potential services under indefinite-delivery, indefinite-quantity agreements in its remaining performance obligations. If any of the Company’s contracts were to be terminated, its remaining performance obligations would be reduced by the expected value of the cancelled performance obligations of such contracts.

In March, May, and October 2022, the Company entered into three inventory loans that each required a cash deposit into an escrow fund. See Note 4, Inventories, of this Quarterly Report on Form 10-Q. 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.

INVENTORIES

Centrus holds uranium at licensed locations (e.g., fabricators) in the form of natural uranium hexafluoride and as the uranium component of LEU in transit to meet book transfer requests by customers and suppliers. Centrus also holds SWU as the SWU component of LEU at licensed locations or in transit 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):

	March 31, 2024						December 31, 2023
	Current Assets		Current Liabilities (a)		Inventories, Net		Current Assets		Current Liabilities (a)		Inventories, Net

Total	$	279.2	$	21.6	$	257.6	$	306.4	$	84.3	$	222.1

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

Inventories are valued at the lower of cost or net realizable value.

The Company also may 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 2023, the Company borrowed UF6 which was recorded to inventory at a value of $22.5 million, based on the estimated fair market value of the inventory on the date of borrowing.

The Company performs quarterly revaluations of the Long-Term Inventory Loans reflecting an updated projection of the timing and sources of inventory to be used for repayment. These revaluations were recorded to Cost of Sales and resulted in an increase to the related liability of $0.3 million and $2.1 million, for the three months ended March 31, 2024 and 2023, respectively.

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):

(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 March 31, 2024, and December 31, 2023, 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.

Net Income (Loss) Per Share

NET INCOME (LOSS) PER SHARE

Basic net income (loss) per share is calculated by dividing net income (loss) 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 common shares related to stock compensation awards including restricted stock, stock options, stock appreciation rights and notional stock units, and the Warrant. No dilutive effect is recognized in a period in which a net loss has occurred.

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

COMMITMENTS AND CONTINGENCIES

Commitments under SWU Purchase Agreements

TENEX

The Russian government-owned entity TENEX is a major supplier of SWU to the Company. Under the 2011 TENEX Supply Contract, the Company purchases SWU contained in LEU received from TENEX, and the Company delivers natural uranium hexafluoride 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, 2023. As a result of exercising this right to reschedule, the Company has 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 the Orano Supply Agreement with a French company, Orano Cycle, for the long-term supply of SWU contained in LEU. The Orano Supply Agreement subsequently was assigned by Orano Cycle to its affiliate, Orano CE. 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.

Milestones Under the 2002 DOE-USEC Agreement

The Company’s predecessor, USEC Inc., and DOE signed the 2002 DOE-USEC Agreement dated June 17, 2002, 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 milestones 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, USEC-Government entered into a lease for the Paducah and Portsmouth GDPs with the DOE. As part of that lease, DOE and USEC-Government also entered into a Power 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 Enrichment Corp., now a principal subsidiary of the Company. 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 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 undergo D&D. According to DOE, the power purchase agreement with Electric Energy Inc. 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 of DOE’s claim nor is it able to estimate its potential liability, if any, for such claim 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 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 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 the Company’s 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 NRC’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, Enrichment Corp., and the other defendants filed their answer to the Lykins Complaint. The Company and Enrichment Corp. believe that their operations at the Portsmouth GDP site were fully in compliance with the NRC’s regulations. Further, the Company and Enrichment Corp. believe that any such liability should be indemnified by DOE 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 March 8, 2023, the Company, Enrichment Corp., and six other DOE contractors that operated facilities at the Portsmouth GDP were named as defendants in a complaint filed by Christian Rose in the U.S. District Court in the Southern District of Ohio, Eastern Division (“Rose Complaint”). Christian Rose was diagnosed with cancer in June 2022. Although Mr. Rose is an adult, he attended the Zahn Corner Middle School, which was closed a few years ago due to contamination and is in the vicinity of the plant. The Rose Complaint alleges that the defendants released radiation into the environment in violation of the Price-Anderson Act causing death – even though the plaintiff is still alive – and seeks monetary damages in the nature of past and future medical expenses, pain and suffering and punitive damages, among others. On May 15, 2023, the Company, Enrichment Corp. and the other defendants filed their answers to the Rose Complaint. The Company and Enrichment Corp. believe that their operations at the Portsmouth GDP site were fully in compliance with the NRC’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 the DOE required to invoke indemnification under the Price-Anderson Act and other contractual provisions.

On November 27, 2023, 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 Joshua Shaw in the U.S. District Court in the Southern District of Ohio, Eastern Division (“Shaw Complaint”). Joshua Shaw was diagnosed with Acute Myeloid Leukemia (AML) in August 2008 and after going through chemotherapy continues to experience aftereffects of AML, including anxiety and fatigue. The Shaw Complaint alleges that the defendants released radiation into the environment exposing Mr. Shaw to radiation in violation of the Price-Anderson Act and causing Mr. Shaw’s AML and other injuries. Mr. Shaw seeks monetary damages in the nature of past and future medical expenses for treatment and care, pain and suffering and punitive damages, among others. The Company and Enrichment Corp. believe that their operations at the Portsmouth GDP site were fully in compliance with the NRC’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 the 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, 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.

Income Taxes

INCOME TAXES

Centrus follows the asset and liability approach to account for deferred taxes. Deferred tax assets and liabilities are recognized for the anticipated future tax consequences of temporary differences between the balance sheet carrying amounts of assets and liabilities and their respective tax bases. A valuation allowance is provided if it is more likely than not that all, or some portion, of the deferred tax assets may not be realized. The ultimate realization of the net deferred tax assets is dependent upon generating sufficient taxable income in future years when deferred tax assets are recoverable or are expected to reverse.

Centrus evaluated both positive and negative evidence that was objectively verifiable to determine the amount of the federal valuation allowance that was required on Centrus’ federal deferred tax assets. Centrus has visibility on a significant portion of revenue in the LEU segment for 2023 through 2026, primarily from its long-term sales contracts. In the third quarter of 2023, Centrus released $7.7 million of the valuation allowance against federal net deferred taxes as a discrete item for the three months ended September 30, 2023. Centrus determined that the positive evidence of increased forecasted future income in the LEU segment based on existing sales Order Book and supply contracts along with commodity market forward pricing indicators, supported the release of the federal valuation allowance. However, due to lack of objectively verifiable information in later years, it was determined that forecasted future income was not sufficient to realize all the deferred tax assets. Therefore, Centrus recorded a partial release of its federal valuation allowance.

Going forward, Centrus will continue to evaluate both positive and negative evidence that would support any further changes to the remaining valuation allowances. Such evidence in its technical solutions segment may include signing new contracts which could have a significant impact on pre-tax income, follow on-work related to the HALEU program, or abandonment of the commercial deployment of the centrifuge technology. Such evidence in our LEU segment may include renewing SWU sales contracts with existing customers and/or signing new SWU sales or purchase contracts with significantly higher or lower margins than currently forecasted. Additional evidence in the LEU segment may include potential deferrals in the timing of deliveries requested by its customers, which would impact revenue recognition timing. The impact of these and other potential positive and negative events will be weighed and evaluated to determine if the valuation allowance should be increased or decreased in the future.
