1. Nature of Business and Summary of Significant Accounting Policies

Nature of Business

Mirion Technologies, Inc. (“Mirion,” the “Company," "we," "our," or "us" and formerly GS Acquisition Holdings Corp II ("GSAH")) is a global provider of radiation detection, measurement, analysis, and monitoring products and services to the medical, nuclear, and defense end markets. On October 20, 2021, Mirion Technologies, Inc. was formed (formerly known as GS Acquisition Holdings Corp II or "GSAH") when it consummated its business combination with GSAH (the "Business Combination") pursuant to the Business Combination Agreement dated June 17, 2021.

We provide products and services through our two operating and reportable segments; (i) Medical and (ii) Nuclear & Safety (formerly Technologies). The Medical segment provides radiation oncology quality assurance, delivering patient safety solutions for diagnostic imaging and radiation therapy centers around the world, dosimetry solutions for monitoring the total amount of radiation medical staff members are exposed to over time, radiation therapy quality assurance solutions for calibrating and verifying imaging and treatment accuracy, and radionuclide therapy products for nuclear medicine applications such as shielding, product handling, and medical imaging furniture. The Nuclear & Safety segment provides robust, field ready personal radiation detection and identification equipment for defense applications and radiation detection and analysis tools for power plants, labs, and research applications. Nuclear power plant product offerings are used for the full nuclear power plant lifecycle including core detectors and essential measurement devices for new build, maintenance, decontamination and decommission equipment for monitoring and control during fuel dismantling and remote environmental monitoring.

The Company is headquartered in Atlanta, Georgia and has operations in the United States, Canada, the United Kingdom, France, Germany, Finland, China, Belgium, the Netherlands, Estonia, Japan, and South Korea.

Basis of Presentation and Principles of Consolidation

The accompanying unaudited Condensed Consolidated Financial Statements and Notes to Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for financial statements and pursuant to the accounting and disclosure rules and regulations of the U.S. Securities and Exchange Commission (the "SEC") for interim financial information. The interim unaudited Condensed Consolidated Financial Statements reflect all adjustments that are of a normal recurring nature and that are considered necessary for a fair representation of the results for the periods presented and should be read in conjunction with the audited Consolidated Financial Statements and notes thereto for the period ended December 31, 2024, which include a complete set of footnote disclosures, including our significant accounting policies included in our Annual Report on Form 10-K. The results for interim periods are not necessarily indicative of the results that may be expected for a full fiscal year or for any other future period. The unaudited Condensed Consolidated Financial Statements include the accounts of the Company and its wholly owned and majority-owned or controlled subsidiaries. For consolidated subsidiaries where our ownership is less than 100%, the portion of the net income or loss allocated to noncontrolling interests is reported as “Income (Loss) attributable to noncontrolling interests” in the unaudited Condensed Consolidated Statements of Operations. All intercompany accounts and transactions have been eliminated in consolidation.

The Company recognizes a noncontrolling interest for the portion of Class B common stock of Mirion IntermediateCo, Inc., a Delaware corporation and direct subsidiary of the Company ("IntermediateCo") that is not attributable to the Company. See Note 18, Noncontrolling Interests.

Segments

The Company manages its operations through two operating and reportable segments: Medical and Nuclear & Safety. These segments align the Company’s products and service offerings with customer use in medical and industrial markets and are consistent with how the Company’s Chief Executive Officer, its Chief Operating Decision Maker (“CODM”), reviews and evaluates the Company’s operations. The CODM allocates resources and evaluates the financial performance of each operating segment. The Company’s segments are strategic businesses that are managed separately because each one develops, manufactures and markets distinct products and services. Refer to Note 14, Segment Information, for further detail.

Use of Estimates
Management estimates and judgments are an integral part of financial statements prepared in accordance with GAAP. We believe that the critical accounting policies listed below address the more significant estimates required of management when preparing our consolidated financial statements in accordance with GAAP. We consider an accounting estimate critical if changes in the estimate may have a material impact on our financial condition or results of operations. We believe that the accounting estimates employed are appropriate and resulting balances are reasonable; however, actual results could differ from the original estimates, requiring adjustment to these balances in future periods. The accounting policies that reflect our more significant estimates, judgments and assumptions and which we believe are the most critical to aid in fully understanding and evaluating our reported financial results include but are not limited to: goodwill and intangible assets; estimated progress toward completion for certain revenue contracts; uncertain tax positions and tax valuation allowances and derivative warrant liabilities.
Significant Accounting Policies

There have been no material changes in our significant accounting policies during the three months ended March 31, 2025, as compared to the significant accounting policies described in Note 1 to the audited consolidated financial statements on Form 10-K for the period ended December 31, 2024.
Accounts Receivable and Allowance for Doubtful Accounts
The allowance for doubtful accounts is based on the Company’s assessment of the collectability of customer accounts. The allowance for doubtful accounts was $5.5 million and $5.2 million as of March 31, 2025 and December 31, 2024, respectively.
Prepaid Expenses and Other Current Assets
Prepaid expenses and other current assets are primarily comprised of various prepaid assets including prepaid insurance, short-term marketable securities, and income tax receivables.
The components of prepaid expenses and other current assets consist of the following (in millions):
March 31, 2025 December 31, 2024
Prepaid insurance $ 3.2  $ 1.0 
Prepaid vendor deposits 4.1  5.4 
Prepaid software expenses 6.3  6.8 
Short-term marketable securities 5.9  5.9 
Income tax receivable and prepaid income taxes 6.0  8.6 
Other tax receivables 1.3   
Other current assets 14.2  13.6 
$ 41.0  $ 41.3 
Facility and Equipment Decommissioning Liabilities
The Company has asset retirement obligations (“ARO”) consisting primarily of equipment and facility decommissioning costs. ARO liabilities totaled $3.1 million for both periods ended March 31, 2025 and December 31, 2024, and were included in other accrued expenses and other long-term liabilities on the unaudited Condensed Consolidated Balance Sheet. Accretion expense related to these liabilities was not material for any periods presented.

Table of Contents
Revenue Recognition
The Company recognizes revenue from arrangements that include performance obligations to design, engineer, manufacture, deliver, and install products. If a performance obligation does not qualify for over-time revenue recognition, revenue is then recognized at the point-in-time in which control of the distinct good or service is transferred to the customer, typically based upon the terms of delivery.
Revenue derived from passive dosimetry and analytical services is of a subscription nature and is provided to customers on an agreed-upon recurring monthly, quarterly or annual basis. Revenue is recognized ratably over the service period as the service is continuous, and no other discernible pattern of recognition is evident.
Contract Balances
The timing of the Company's revenue recognition, invoicing, and cash collections results in accounts receivable, costs and estimated earnings in excess of billings on uncompleted contracts, and deferred contract revenue. Refer to Note 3, Contracts in Progress, for further details.
Remaining Performance Obligations
The remaining performance obligations for all open contracts as of March 31, 2025 include assembly, delivery, installation, and trainings. The aggregate amount of the transaction price allocated to the remaining performance obligations for all open customer contracts was approximately $813.5 million and $811.9 million as of March 31, 2025 and December 31, 2024, respectively. As of March 31, 2025, the Company expects to recognize approximately 47%, 22%, 9%, and 5% of the remaining performance obligations as revenue during 2025, 2026, 2027 and 2028, respectively, and the remainder thereafter.
Disaggregation of Revenues
A disaggregation of the Company’s revenues by segment, geographic region, timing of revenue recognition and product category is provided in Note 14, Segment Information.
Warrant Liability

As of March 31, 2024, the Company had outstanding warrants to purchase up to 27,249,779 shares of Class A common stock. The Company accounted for the warrants in accordance with the guidance contained in ASC 815, “Derivatives and Hedging”, under which the warrants did not meet the criteria for equity treatment and were required to be recorded as derivative liabilities. Accordingly, the Company classified the warrants as liabilities at their fair value and adjusted the warrants to fair value at each reporting period. This liability was subject to re-measurement at each balance sheet date until the warrants were exercised or expired, and any change in fair value was recognized in the Company’s unaudited Condensed Consolidated Statements of Operations. The fair value of the warrants (the "Public Warrants") issued in connection with GSAH's initial public offering had been measured based on the listed market price of such Public Warrants. As the transfer of certain warrants issued in a private placement (the "Private Placement Warrants" and, together with the Public Warrants, the "Warrants") to GS Sponsor II LLC, the sponsor of GSAH (the "Sponsor"), to anyone who was not a permitted transferee would result in the Private Placement Warrants having substantially the same terms as the Public Warrants, we determined that the fair value of each Private Placement Warrant was equivalent to that of each Public Warrant. Derivative warrant liabilities were classified as non-current liabilities as their liquidation was not reasonably expected to require the use of current assets or require the creation of current liabilities.

During the three months ended March 31, 2024, the Company recognized a $5.7 million gain resulting from the change in fair value of warrant liabilities within the unaudited Condensed Consolidated Statements of Operations.

On April 18, 2024, the Company called the Public Warrants for redemption per the Company's rights under the warrant agreement. After April 18, 2024 and prior to 5:00 pm New York City time on Monday, May 20, 2024 (the "Redemption Date"), Public Warrant holders were entitled to exercise (i) in cash, at an exercise price of $11.50 per share of Class A common stock, or (ii) on a cashless basis in which the exercising holder was entitled to receive 0.22 shares of Class A common stock per Warrant. The number of shares provided to the warrant holder was determined in accordance with the terms of the warrant agreement, whereby the number of shares received in a cashless exercise was based upon the Redemption Date and the average last reported sale price of Class A common stock for the ten trading days ending on the third trading day prior to the notice of Redemption Date. The Public Warrants were valued using the listed trading price as of close on the trading day prior to the relevant settlement date of exercise. Any Warrants not exercised by the Redemption Date were automatically redeemed by the Company at a price of $0.10 per Warrant. In connection with the Redemption, approximately 18,076,416 Public Warrants were exercised, representing approximately 96% of the outstanding Public Warrants, and 3,978,418 shares of Class A common stock were issued upon exercise of such Warrants. Total cash proceeds generated from exercises of the Public Warrants were immaterial, and the Company made an immaterial redemption payment to the holders of the 673,363 redeemed Public Warrants. Following the Redemption Date, the Public Warrants stopped trading on NYSE and were delisted.
On June 4, 2024, the Company exchanged 1,768,000 shares of the Company's Class A common stock for 8,500,000 Private Placement Warrants via a warrant exchange agreement. The number of shares of Class A common stock to be exchanged on a cashless basis was determined using the same methodology applied to the Public Warrants. The Company valued the Private Placement Warrants on the settlement date of exercise, using the fair market value of the Company's Class A common stock as of close on a trading day prior to the settlement date multiplied by the number of shares of Class A common stock to be issued per Warrant, which was determined in accordance with the terms of the warrant exchange agreement.
Treasury Stock
We account for treasury stock under the cost method pursuant to the provisions of ASC 505-30, Treasury Stock. Under the cost method, the gross cost of the shares reacquired is charged to a contra equity account, treasury stock. The equity accounts that were originally credited for the original share issuance, Common Stock and additional paid-in capital, remain intact.
When treasury shares are reissued at a price higher than cost, the difference is recorded as a component of additional paid-in-capital in the unaudited Condensed Consolidated Balance Sheets. When treasury stock is re-issued at a price lower than its cost, the difference is recorded as a component of additional paid-in-capital to the extent that previously recorded gains exist to offset the losses. If there are no treasury stock gains in additional paid-in-capital, the losses upon re-issuance of treasury stock are recorded as a reduction of retained earnings in the unaudited Condensed Consolidated Balance Sheets. Treasury stock is reissued on a FIFO cost flow basis to compute excesses and deficiencies upon subsequent share reissuance.
Concentrations of Risk
Financial instruments that are potentially subject to concentration of credit risk consist primarily of cash, cash equivalents, and accounts receivable. The Company maintains cash in bank deposit accounts that, at times, may exceed the insured limits of the local country. The Company has not experienced any losses in such accounts.
The Company sells its products and services mainly to large, private and governmental organizations in the Americas, Europe, the Middle East and Asia Pacific regions. The Company performs ongoing evaluations of its customers’ financial condition and limits the amount of credit extended when deemed necessary. The Company generally does not require its customers to provide collateral or other security to support accounts receivable. As of March 31, 2025 and December 31, 2024, no customer accounted for more than 10% of the accounts receivable balance. No single customer accounted for more than 10% of total revenues during the three months ended March 31, 2025, and March 31, 2024, respectively.

Recent Accounting Pronouncements
Accounting Guidance Issued and Adopted
In November 2023, the FASB issued ASU 2023-07 "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures". ASU 2023-07 improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments were effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company adopted this guidance during the fourth quarter of 2024 and implemented the required disclosures, including applying retrospectively to all prior periods presented in the condensed consolidated financial statements. See Note 14, Segment Information.
Accounting Guidance Issued But Not Yet Adopted
In October 2023, the FASB issued ASU 2023-06 “Disclosure Improvements”. ASU 2023-06 clarifies or improves disclosure and presentation requirements of a variety of topics. For entities subject to the SEC’s existing disclosure requirements, the effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. For all entities, if by June 30, 2027, the SEC has not removed the applicable requirement from Regulation S-X or Regulation S-K, the pending content of the related amendment will be removed from the codification and will not become effective for any entity. The Company is currently evaluating the impact of this ASU.

In December 2023, the FASB issued ASU 2023-09 "Income Taxes (Topic 740): Improvements to Income Tax Disclosures". ASU 2023-09 enhances the existing income tax disclosures primarily related to the rate reconciliation and income taxes paid information. For public business entities, the amendments are effective for annual periods beginning after December 15, 2024, with early adoption permitted for annual financial statements that have not yet been issued or made available for issuance. The amendments will be applied on a prospective basis, with retrospective application permitted. The Company is currently evaluating the impact of this ASU.
In November 2024, the FASB issued ASU 2024-3 "Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures." The ASU will improve the decision usefulness for investors by requiring public business entities to disclose more detailed information about their expenses such as (a) inventory and manufacturing expense, (b) employee compensation, (c) depreciation, (d) intangible asset amortization, etc. The amendments will be effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The amendments will be applied prospectively with an option for a retrospective application. The Company is evaluating the impact of this new standard and believes that the adoption will result in additional disclosures, but will not have any other impact on its consolidated financial statements.

6. Goodwill and Intangible Assets
Goodwill
Goodwill is calculated as the excess of consideration transferred over the net assets recognized for acquired businesses and represents future economic benefits arising from the other assets acquired that could not be individually identified and separately recognized. Goodwill is assigned to reporting units at the date the goodwill is initially recorded and is reallocated as necessary based on the composition of reporting units over time.
The Company assesses goodwill for impairment at the reporting unit level annually on the first day of the fourth quarter and upon the occurrence of a triggering event or change in circumstance that would more likely than not reduce the fair value of a reporting unit below its carrying amount.
A quantitative test performed upon the occurrence of a triggering event compares the fair value of a reporting unit with its carrying amount. The Company determines fair values for each of the reporting units, as applicable, using the market approach, when available and appropriate, or the income approach, or a combination of both. The Company assesses the valuation methodology based upon the relevance and availability of the data at the time the Company performs the valuation. If multiple valuation methodologies are used, the results are weighted appropriately.
Valuations using the market approach are derived from metrics of publicly traded companies or historically completed transactions of comparable businesses. The selection of comparable businesses is based on the markets in which the reporting units operate giving consideration to risk profiles, size, geography, and diversity of products and services. A market approach is limited to reporting units for which there are publicly traded companies that have characteristics similar to the Company's businesses.

Under the income approach, fair value is determined based on the present value of estimated future cash flows, discounted at an appropriate risk-adjusted rate. The Company uses its internal forecasts to estimate future cash flows and include an

17

Table of Contents
estimate of long-term future growth rates based on our most recent views of the long-term outlook for each business. Actual results may differ from those assumed in the forecasts. The Company derives its discount rates using a capital asset pricing model and by analyzing published rates for industries relevant to its reporting units to estimate the cost of equity financing. The Company uses discount rates that are commensurate with the risks and uncertainty inherent in the respective businesses and in internally developed forecasts.
No goodwill impairment was recognized for the three months ended March 31, 2025 and March 31, 2024, respectively.
The following table shows changes in the carrying amount of goodwill by reportable segment as of March 31, 2025 and December 31, 2024 (in millions):

As of March 31, 2025 and December 31, 2024, the fair market value of the Company's 2021 Credit Agreement (defined below) was $691.1 million and $696.3 million, respectively. The fair market value for the 2021 Credit Agreement was estimated using primarily level 2 inputs, including borrowing rates available to the Company at the respective period ends. The fair market value for the Company’s remaining third-party debt approximates the respective carrying amounts as of March 31, 2025 and December 31, 2024.
2021 Credit Agreement
The Company maintains a credit agreement (the “2021 Credit Agreement”) among Mirion IntermediateCo Inc., a Delaware corporation, as Holdings, Mirion Technologies (US Holdings), Inc., as the Parent Borrower, Mirion Technologies (US), Inc., as the Subsidiary Borrower, the lending institutions party thereto, and Citibank, N.A., as the Administrative Agent and Collateral Agent.
The 2021 Credit Agreement provides for an $830.0 million senior secured first lien term loan facility and a $175.0 million senior secured revolving facility (collectively, the “Credit Facilities”). The term loan facility is scheduled to mature on October 20, 2028, and the revolving facility is scheduled to expire and mature on March 21, 2030 (subject to other terms and conditions). The agreement requires the payment of a commitment fee of 0.50% per annum for unused revolving commitments, subject to stepdowns to 0.375% per annum and 0.25% per annum upon the achievement of specified leverage ratios. Any outstanding letters of credit issued under the 2021 Credit Agreement reduce the availability under the revolving line of credit.
The 2021 Credit Agreement is secured by a first priority lien on the equity interests of the Parent Borrower owned by Holdings and substantially all of the assets (subject to customary exceptions) of the borrowers and the other guarantors thereunder. Interest with respect to the facilities is based on, at the option of the borrowers, (i) a customary base rate formula for borrowings in U.S. dollars or (ii) a floating rate formula based on LIBOR (with customary fallback provisions) for borrowings in U.S. dollars, a floating rate formula based on Euro Interbank Offered Rate ("EURIBOR") for borrowings in Euro or a floating rate formula based on SONIA for borrowings in Pounds Sterling, each as described in the 2021 Credit Agreement with respect to the applicable type of borrowing. The 2021 Credit Agreement includes fallback language that seeks to either facilitate an agreement with the Company's lenders on a replacement rate for LIBOR in the event of its discontinuance or that automatically replaces LIBOR with benchmark rates based upon the Secured Overnight Financing Rate ("SOFR") or other benchmark replacement rates upon certain triggering events (SOFR was adopted pursuant to an amendment to the 2021 Agreement in replacement of LIBOR in 2023).


19

Table of Contents
The 2021 Credit Agreement contains customary representations and warranties as well as customary affirmative and negative covenants and events of default. The negative covenants include, among others and in each case subject to certain thresholds and exceptions, limitations on incurrence of liens, limitations on incurrence of indebtedness, limitations on making dividends and other distributions, limitations on engaging in asset sales, limitations on making investments, and a financial covenant that the “First Lien Net Leverage Ratio” (as defined in the 2021 Credit Agreement) as of the end of any fiscal quarter is not greater than 7.00 to 1.00 if on the last day of such fiscal quarter certain borrowings outstanding under the revolving credit facility exceed 40% of the total revolving credit commitments at such time. The covenants also contain limitations on the activities of Mirion IntermediateCo, Inc. as the “passive” holding company. If any of the events of default occur and are not cured or waived, any unpaid amounts under the 2021 Credit Agreement may be declared immediately due and payable, the revolving credit commitments may be terminated and remedies against the collateral may be exercised. Mirion IntermediateCo, Inc. was in compliance with all debt covenants on March 31, 2025 and December 31, 2024.

Term Loan - The term loan has a seven-year term (expiring October 2028) and bears interest at the greater of LIBOR (through June 30, 2023) / SOFR (subsequent to June 30, 2023 through May 21, 2024) or 0.50%, plus 2.75%. On May 22, 2024, the Company entered into Amendment No. 3 (the “Amendment”) to the Credit Agreement. The Amendment reduced the applicable margin rate on the term loans from 2.75% to 2.25% and reduced the credit spread based upon rate term to 0%, with other terms and conditions remaining consistent (effectively the existing loan was refinanced). The Amendment was accounted for prospectively as a debt modification in accordance with ASC 470-50, Debt—Modifications and Extinguishments. The interest rate was 6.55% and 6.85% as of March 31, 2025 and December 31, 2024, respectively. The Company paid no principal payments for the three months ended March 31, 2025 and for year ended December 31, 2024, respectively, yielding an outstanding balance of approximately $694.6 million as of March 31, 2025 and December 31, 2024.
Revolving Line of Credit - The revolving line of credit arrangement initially had a five-year term (expiring October 2026) and bore interest at the greater of LIBOR (through June 30, 2023) / SOFR (subsequent to June 30, 2023) or 0%, plus 2.25%. The terms of the revolving line of credit were amended on March 21, 2025, through Amendment No. 4 to the 2021 Credit Agreement. Under the new amendment, revolving credit commitments from lenders increased from $90.0 million to $175.0 million, and the maturity date extended to March 21, 2030, subject to a “springing” maturity date that is 91 days prior to the maturity date of the outstanding term loan under the 2021 Credit Agreement (but only to the extent the outstanding principal amount of the term loan exceeds $100.0 million on the date of determination, and a final stated maturity date that is earlier than 91 days after March 21, 2030).
The agreement requires the payment of a commitment fee of 0.25% per annum for unused commitments. Any outstanding letters of credit reduce the availability of the revolving line of credit. There was no outstanding balance under the arrangement as of March 31, 2025 and December 31, 2024. Additionally, the Company has standby letters of credit issued under its 2021 Credit Agreement that reduce the availability under the revolver of $18.0 million and $17.9 million for the periods ended March 31, 2025 and December 31, 2024, respectively. The amount available on the revolver as of March 31, 2025 and December 31, 2024 was approximately $157.0 million and $72.1 million, respectively.
Deferred Financing Costs
In connection with the issuance of the 2021 Credit Agreement term loan, we incurred debt issuance costs of $21.7 million on date of issuance. In accordance with accounting for debt issuance costs, we recognize and present deferred finance costs associated with non-revolving debt and financing obligations as a reduction from the face amount of related indebtedness in the unaudited Condensed Consolidated Balance Sheets.
In connection with the issuance of the 2021 Credit Agreement revolving line of credit, we incurred debt issuance costs of $1.8 million. We recognize and present debt issuance costs associated with revolving debt arrangements as an asset and include the deferred finance costs within other assets in the unaudited Condensed Consolidated Balance Sheets. We amortize all debt issuance costs over the life of the related indebtedness.

In connection with the May 22, 2024 closing of the refinanced Credit Facilities, the Company determined the change would be accounted for prospectively as a debt modification in accordance with ASC 470-50, Debt—Modifications and Extinguishments. As a result, the Company capitalized an additional $1.3 million for the payment of upfront lender fees.

In connection with the March 21, 2025 refinancing of the revolving line of credit under the 2021 Credit Agreement, the Company determined the change would be accounted for prospectively as a debt modification in accordance with ASC 470-50, Debt—Modifications and Extinguishments. As a result, the Company capitalized an additional $0.8 million for debt issuance fees.

Table of Contents
For the three months ended March 31, 2025 and 2024, we incurred approximately $0.9 million and $0.7 million, of amortization expense of the deferred financing costs, respectively.
Overdraft Facilities
The Company has overdraft facilities with certain German and French financial institutions. As of March 31, 2025 and December 31, 2024, there were no outstanding amounts under these arrangements.
Accounts Receivable Sales Agreement
We are party to agreements to sell short-term receivables from certain qualified customer trade accounts to an unaffiliated French financial institution and an unaffiliated Finnish financial institution without recourse. Under these agreements, the Company can sell up to €12.5 million ($13.5 million) and €12.5 million ($13.0 million) as of March 31, 2025 and December 31, 2024, respectively, of eligible accounts receivables. The accounts receivable under these agreements are sold at face value and are excluded from the consolidated balance if revenue has been recognized on the related receivable. When the related revenue has not been recognized on the receivable the Company considers the accounts receivable to be collateral for short-term borrowings. As of March 31, 2025 and December 31, 2024, there was $0.0 million and $0.2 million, respectively, outstanding under these arrangements included as Other in the Borrowings table above.

Total costs associated with this arrangement were immaterial for all periods presented and are included in selling, general and administrative expense in the unaudited Condensed Consolidated Statements of Operations.
Performance Bonds and Other Credit Facilities
The Company has entered into various line of credit arrangements with local banks in France and Germany. These arrangements provide for the issuance of documentary and standby letters of credit of up to €62.8 million ($66.8 million) and €72.6 million ($75.4 million), as of March 31, 2025 and December 31, 2024, respectively, subject to certain local restrictions. As of March 31, 2025 and December 31, 2024, there were €54.5 million ($58.8 million) and €56.0 million ($58.2 million), respectively, of the lines that had been utilized to guarantee documentary and standby letters of credit, with interest rates ranging from 0.5% to 2.0%. In addition, the Company posts performance bonds with irrevocable letters of credit to support certain contractual obligations to customers for equipment delivery. These letters of credit are supported by restricted cash accounts, which totaled $0.4 million for both periods ending March 31, 2025 and December 31, 2024, respectively.
At March 31, 2025, contractual principal payments of total third-party borrowings are as follows (in millions):

8. Leased Assets

The Company primarily leases certain logistics, office, and manufacturing facilities, as well as vehicles, copiers and other equipment. These operating leases generally have remaining lease terms between 1 month and 30 years, and some include options to extend (generally 1 to 10 years). The exercise of lease renewal options is at the Company’s discretion. The Company evaluates renewal options at lease inception and on an ongoing basis, and includes renewal options that it is reasonably certain to exercise in its expected lease terms when classifying leases and measuring lease liabilities. Lease agreements generally do not require material variable lease payments, residual value guarantees or restrictive covenants.

The depreciable lives are limited by the expected lease term for operating lease assets and by shorter of either the expected lease term or economic useful life for financing lease assets.

The Company’s leases generally do not provide an implicit rate, and therefore the Company uses its incremental borrowing rate as the discount rate when measuring the lease liabilities. The incremental borrowing rate represents an estimate of the interest rate the Company would incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis over the term of the lease within a particular currency environment. The Company used incremental borrowing rates as of July 1, 2021 for leases that commenced prior to that date.

The Company’s weighted average remaining lease term and weighted average discount rate for operating leases as of March 31, 2025 and December 31, 2024, respectively, are:

For the three months ended March 31, 2025, operating lease costs (as defined under ASU 2016-02) were $1.6 million and for the three months ended March 31, 2024 operating lease costs were $2.7 million. Operating lease costs are included within costs of goods sold, selling, general and administrative, and research and development expenses on the unaudited Condensed Consolidated Statements of Operations. Short-term lease costs, variable lease costs and sublease income were not material for the periods presented.

Cash paid for amounts included in the measurement of operating lease liabilities was $2.1 million for both the three months ended March 31, 2025 and March 31, 2024 and these amounts are included in operating activities in the unaudited Condensed Consolidated Statements of Cash Flows.

9. Commitments and Contingencies
Unconditional Purchase Obligations
The Company has entered into certain long-term unconditional purchase obligations with suppliers. These agreements are non-cancellable and specify terms, including fixed or minimum quantities to be purchased, fixed or variable price provisions, and the approximate timing of payment. As of March 31, 2025, unconditional purchase obligations were as follows (in millions):
Year ending December 31:
2025 $ 67.3 
2026 9.4 
2027 1.4 
2028 0.5 
2029 and thereafter 0.3 
Total $ 78.9 
Litigation
The Company is subject to various legal proceedings, claims, litigation, investigations and contingencies arising out of the ordinary course of business. While the ultimate results of such suits or other proceedings against the Company cannot be predicted with certainty, we believe the resolution of these matters will not have a material effect on our results of operations, financial condition, or cash flows. If we believe the likelihood of an adverse legal outcome is probable and the amount is reasonably estimable, we accrue a liability in accordance with accounting guidance for contingencies. We consult with legal counsel on matters related to litigation and seek input both within and outside the Company.

In April 2023, one of our Russian customers made a claim against the Company, including liquidated damages for certain delays under the terms of an active project, in the amount of $19.3 million, and sent an updated claim statement in October 2023 totaling $21 million ($18 million of which accrue daily penalties), subject to a $14 million contractual cap (all amounts converted from Euros to U.S. Dollars). In November 2024, the Company reached an agreement to modify the underlying contract and the claim was rescinded by the customer. The modification was accounted for under ASC 606 Revenue Recognition which resulted in an immaterial impact to the Consolidated Statement of Operations for the fiscal year ended December 31, 2024.

In June 2023, the same Russian customer made a demand against the Company for the return of all payments received by the Company ($10.2 million) related to a Finland nuclear power plant project cancelled in May 2022. In September 2024, the Company entered into a settlement agreement with the customer agreeing to refund €4.4 million to the customer. The amount is included in Accrued expenses and other current liabilities in the unaudited Condensed Consolidated Balance Sheet as of March 31, 2025, and the settlement resulted in an immaterial impact to the unaudited Condensed Statement of Operations for the fiscal year ended December 31, 2024.
10. Income Taxes
The effective income tax rate was 33.3% and (4.7)% for the three months ended March 31, 2025 and 2024, respectively. The difference in effective tax rate between the periods was primarily attributable to mix of earnings and the impact of valuation allowances.
The effective income tax rate differs from the U.S. statutory rate of 21% due primarily to U.S. federal income tax permanent differences and the impact of valuation allowances.
The OECD (Organisation for Economic Co-operation and Development) has proposed a global minimum tax of 15% of reported profits (Pillar Two) and many countries have incorporated Pillar Two model rule concepts into their domestic laws. Pillar Two legislation is effective for the Company for the year ended December 31, 2025. Although the model rules provide a framework for applying the minimum tax, countries may enact Pillar Two slightly differently than the model rules and on different timelines. For the three months ended March 31, 2025, the impact of Pillar Two on our consolidated financial statements was not material.

12. Stock-Based Compensation
Stock-based compensation is awarded to employees and directors of the Company and accounted for in accordance with ASC 718, "Compensation—Stock Compensation". Stock-based compensation expense is recognized for equity awards over the vesting period based on their grant-date fair value. Stock-based compensation expense is included within the same financial statement caption where the recipient’s other compensation is reported. The Company accounts for forfeitures as they occur. The Company uses various forms of long-term incentives including, but not limited to restricted stock units ("RSUs") and performance-based restricted units ("PSUs"), provided that the granting of such equity awards is in accordance with the Company's 2021 Omnibus Incentive Plan (the "2021 Plan") as filed on Form S-8 with the SEC on December 27, 2021.

Table of Contents
2021 Omnibus Incentive Plan

We adopted and obtained stockholder approval at the special meeting of the stockholders on October 19, 2021 of the 2021 Plan. We initially reserved 19,952,329 shares of our Class A common stock for issuance pursuant to awards under the 2021 Plan. The total number of shares of our Class A common stock available for issuance under the 2021 Plan will be increased on the first day of each fiscal year following the date on which the 2021 Plan was adopted in an amount equal to the least of (i) three percent (3%) of the outstanding shares of Class A common stock on the last day of the immediately preceding fiscal year, (ii) 9,976,164 shares of Class A common stock and (iii) such number of shares of Class A common stock as determined by the Committee (as defined and designated under the 2021 Plan) in its discretion. Pursuant to these automatic increase provisions, the number of shares of our Class A common stock reserved for issuance pursuant to awards under the 2021 Plan increased to 45,269,801 shares at January 1, 2025 (excluding the impact of grants and forfeitures plan to date). Any employee, director or consultant of the Company or any of its subsidiaries or affiliates is eligible to receive an award under the 2021 Plan, to the extent that an offer of such award is permitted by applicable law, stock market or exchange rules, and regulations or accounting or tax rules and regulations. The 2021 Plan provides for the grant of stock options (including incentive stock options and non-qualified stock options), stock appreciation rights, restricted stock, RSUs, PSUs, other stock-based awards, or any combination thereof. Each award will be set forth in a separate grant notice or agreement and will indicate the type and terms and conditions of the award.
The purpose of the 2021 Plan is to motivate and reward employees and other individuals to perform at their highest level and contribute significantly to the success of the Company. During the three months ended March 31, 2025, the Company granted 207,999 RSUs and 625,550 PSUs to certain employees. During the three months ended March 31, 2024, the Company granted 548,939 RSUs and 453,560 PSUs to certain employees. The RSUs granted to employees are subject to service vesting conditions such that all awards are fully vested after three (3) years with equal annual installments vesting on the anniversary of the grant date. The expense will be recognized on a straight-line basis over the related service period for each tranche of awards.

The PSUs granted during the three months ended March, 31, 2025, and 2024 vest over a three-year performance period beginning on January 1 of the grant year and are subject to service and performance/market vesting conditions. The number of PSUs to be earned is determined based upon attainment of certain performance goals over the course of the performance period. The recipient will generally forfeit all of the awards if the recipient is no longer providing services to the Company before the end of the performance measurement period. PSUs are considered variable in that compensation could range from zero to 200% of the award agreement's target contingent on the performance level attained. Fifty percent (50%) of the PSU awards shall vest based a performance condition determined by the Company's adjusted EBITDA with interpolated achievement levels. The remaining fifty percent (50%) of the PSU awards shall vest based on a performance condition determined by the Company’s cumulative adjusted free cash flow ("adjusted cash flow") with interpolated achievement levels. If certain minimum performance levels are not attained in the performance period, none of the PSUs will become vested. The overall payout result per the performance conditions shall be adjusted based on a market condition modifier (+/- 25% for 2025 grants, +/- 10% for 2024 grants) determined by the Company's relative total shareholder return (TSR) during the respective performance period, measured as a comparative percentile to the Company’s peers in the Russell 2000 Industrials index.

During the three months ended March 31, 2025, $3.3 million of stock-based compensation expense was recorded, of which $0.2 million was related to non-employee directors. During the three months ended March 31, 2024, $2.6 million of stock-based compensation expense was recorded, of which $0.2 million was related to non-employee directors.
In addition, during the three months ended March 31, 2025 certain members of the Company's Directors elected to receive their quarterly retainer fees in the form of shares of Class A common stock. As such, the Company recorded related stock-based compensation expense for $0.1 million. During the three months ended March 31, 2024, the Company recorded related stock-based compensation expense for $0.1 million for the director payments in lieu of cash.

Profits Interests

On June 17, 2021 the Sponsor issued 4,200,000 Profits Interests to Lawrence Kingsley, then the Chairman of the Board of Directors of the Company, 3,200,000 Profits Interests to Thomas Logan, the Chief Executive Officer of Mirion, and 700,000 Profits Interests to Brian Schopfer, the Chief Financial Officer of Mirion. The Profits Interests were intended to be treated as profits interests for U.S. income tax purposes, pursuant to which Messrs. Logan, Schopfer and Kingsley had an indirect interest in the founder shares held by the Sponsor; see Note 13, Related-Party Transactions, for further details. The Profits Interests vested in full and therefore all related expenses were completed at the end of fiscal year 2024. During the three ended March 31, 2024, $0.9 million of stock-based compensation expense was recorded.

13. Related-Party Transactions
Founder Shares

The former sponsor of GS Acquisition Holdings Corp II ("GSAH"), with which the Company consummated its business combination on October 21, 2021, owned 18,750,000 shares of Class B common stock ("founder shares"), which automatically converted into 18,750,000 shares of Class A common stock at the closing of the business combination. The founder shares, were subject to certain vesting and forfeiture conditions and transfer restrictions, including performance vesting conditions under which the price per share of Mirion's Class A common stock must meet or exceed certain established thresholds of $12, $14, or $16 per share for 20 out of 30 trading days before October 20, 2026. During the fourth quarter of the year ended December 31, 2024, all of the founder shares met the required vesting conditions.

Private Placement Warrants

The former sponsor of GSAH purchased an aggregate of 8,500,000 private placement warrants (the "Private Placement Warrants") at a price of $2.00 per whole warrant ($17.0 million in the aggregate) in a private placement (the “Private Placement”) that closed concurrently with the closing of GSAH's initial public offering (the "IPO"). Each Private Placement Warrant was exercisable for one whole share of Class A common stock at a price of $11.50 per share, subject to adjustment in certain circumstances, including upon the occurrence of certain reorganization events. The Private Placement Warrants were non-redeemable and exercisable on a cashless basis so long as they were held by the Sponsor or its permitted transferees.

During the three months ended June 30, 2024, the private placement warrants were exchanged for the Company's Class A common stock. See Note 1, Nature of Business and Summary of Significant Accounting Policies, for further details.

Profits Interests

The former sponsor of GSAH issued 8,100,000 Profits Interests to certain individuals affiliated with or expected to be affiliated with Mirion. The holders of the Profits Interests had an indirect interest in the founder shares held by the former sponsor of GSAH. The Profits Interests were subject to service and performance vesting conditions and fully vested during the fourth quarter of the year ended December 31, 2024. See Note 12, Stock-Based Compensation, for further detail regarding the Profits Interests.
14. Segment Information
During the year ended December 31, 2024, the Company renamed its Technologies segment as "Nuclear & Safety."
The Company manages its operations through two operating and reportable segments: Medical and Nuclear & Safety. These segments align the Company’s products and service offerings to customers and are consistent with how the Company’s Chief Executive Officer, its Chief Operating Decision Maker (“CODM”), reviews and evaluates the Company’s operations. The CODM allocates resources and evaluates the financial performance of each operating segment using operating income (loss). The Company’s segments are strategic businesses that are managed separately because each one develops, manufactures, and markets distinct products and services. The company adopted ASU 2023-07 "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures" as of the year ended December 31, 2024, and applied the requirements of the standard to prior period information retrospectively as required.
Description of Segments

The Medical segment provides solutions focused on ensuring safety of equipment and personnel in the medical field. The primary product category relates to Cancer Care applications, including radiation oncology quality assurance, delivering patient safety solutions for diagnostic imaging and radiation therapy centers around the world, radiation therapy quality assurance solutions for calibrating and verifying imaging and treatment accuracy, and radionuclide therapy products for nuclear medicine applications such as product handling and medical imaging furniture. Other Medical segment products include dosimetry solutions for monitoring the total amount of radiation medical staff members are exposed to over time.

The Nuclear & Safety segment provides radiation detection equipment for power plants, labs and research facilities and industrial and defense applications. Nuclear products are concentrated in power plant product offerings that are used for the full nuclear power plant lifecycle including core detectors and essential measurement devices for new build, maintenance, decontamination and decommission equipment for monitoring and control during fuel dismantling, and remote environmental monitoring. Labs and research and other (primarily industrial and defense) are focused on the area of personal radiation detection for various safety and security requirements.

Table of Contents

The CODM evaluates operating results and allocates capital resources between segments based on segment operating income (loss). Interest income and expense, loss (benefit) from income taxes, foreign currency loss (gain), net, other expense (income), net, and, if applicable, other items such as loss on debt extinguishment, are not allocated to segments.

The following tables summarize information about revenue, significant segment expenses, other segment items, and segment income (loss) from operations for each reportable segment (in millions). Reconciliation of consolidated segment income (loss) from operations to consolidated income (loss) before income taxes is shown in the Total column of each table.

15. Fair Value Measurements
The Company applies fair value accounting to all financial assets and liabilities that are recognized or disclosed at fair value in the consolidated financial statements on a recurring basis. The fair value of the Company’s cash and cash equivalents, restricted cash, accounts receivable, and other current assets and liabilities approximates their carrying amounts due to the relatively short maturity of these items. The fair value of third-party debt approximates the carrying value because the interest rates are variable and reflect market rates.
Fair Value of Financial Instruments
The Company categorizes assets and liabilities recorded at fair value in the unaudited Condensed Consolidated Balance Sheets based upon the level of judgment associated with inputs used to measure their fair value. It is not practicable due to cost and effort for the Company to estimate the fair value of notes issued to related parties primarily due to the nature of their terms relative to the entity’s capital structure.
Assets and liabilities carried at fair value are valued and disclosed in one of the following three levels of the valuation hierarchy:
Level 1 – Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

29

Table of Contents
Level 2 – Inputs are quoted prices in active markets for similar assets or liabilities or inputs that can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3 – Inputs are unobservable and require significant management judgment or estimation.
The following table summarizes the financial assets and liabilities of the Company that are measured at fair value on a recurring basis (in millions):

16. Derivatives and Hedging
The Company's policy requires derivatives to be used solely for managing risks and not for speculative purposes. As a result of the Company’s European operations, the Company is exposed to fluctuations in exchange rates between EUR and USD. As such, the Company entered into cross-currency rate swaps during the year ended December 31, 2022, to manage currency risks related to our investments in foreign operations. During the year ended December 2024, the Company extended a cross-currency rate swap derivative by one year (notional amount of 123.2 million euros). The Company is also subject to interest rate risk related to the Credit Facilities. The Company manages its risk to interest rate fluctuations through the use of derivative financial instruments. As such, the Company entered into an interest rate swap (notional amount of $75.0 million) to mitigate the risk of adverse changes in benchmark interest rates on the Company's future interest payments.
All derivative instruments are carried at fair value in the unaudited Condensed Consolidated Balance Sheets. The following table presents the fair values of the Company’s derivative instruments that were designated and qualified as part of a hedging relationship (in millions):

(1) Refer to Note 15, Fair Value Measurements, for additional information related to the estimated fair value.

Counterparty Credit Risk
Outstanding financial derivative instruments expose the Company to credit loss in the event of nonperformance by the counterparties to the derivative agreements. The Company's credit exposure related to these financial instruments is represented by the notional amount of the hedging instruments. The Company manages its exposure to counterparty credit risk through minimum credit standards, diversification of counterparties, and procedures to monitor concentrations of credit risk. The Company's derivative instruments are with financial institutions of investment grade or better. Counterparty credit risk will be monitored through periodic review of counterparty bank’s credit ratings and public financial filings. Based on these factors, the Company considers the risk of counterparty default to be minimal.

Cash Flow Hedging Strategy
The Company uses cash flow hedges to minimize the variability in cash flows of assets or liabilities or forecasted transactions caused by fluctuations in interest rates. The changes in the fair values of derivatives designated as cash flow hedges are recorded in accumulated other comprehensive loss (“AOCL”) and are reclassified into the line item in the unaudited Condensed Consolidated Statements of Operations in which the hedged items are recorded in the same period the hedged items affect earnings. The changes in the fair values of hedges that are determined to be ineffective are immediately reclassified from AOCL into earnings. The maximum length of time for which the Company hedges its exposure to the variability in future cash flows is three years.

The interest rate swap was entered into by the Company during the second quarter of 2023. During the three months ended March 31, 2025 the interest rate swap resulted in losses of $0.1 million recognized in other comprehensive income ("OCI"). Gains of $0.1 million in income were recognized through interest expense and reclassified from OCI during the same period. During the three months ended March 31, 2024, the interest rate swap resulted in gains of $0.8 million recognized in OCI. Gains of $0.3 million in income were recognized through interest expense and reclassified from OCI during the same period. The cash inflows and outflows associated with the Company’s derivative contracts designated as cash flow hedges are classified as financing activities in the unaudited Condensed Consolidated Statements of Cash Flows. In addition, the Company did not have any ineffectiveness related to the interest rate swap during the three months ended March 31, 2025.

Hedges of Net Investments in Foreign Operations Strategy
The Company uses fixed-to-fixed cross-currency rate swaps ("CCRS") to protect the net investment on pre-tax basis in the Company’s EUR-denominated operations against changes in spot exchange rates. For derivative financial instruments that are designated and qualify as hedges of net investments in foreign operations, the changes in the fair values of the derivative financial instruments are recognized in net investment hedges adjustments, a component of AOCL, to offset the changes in the values of the net investments being hedged. Any ineffective portions of net investment hedges are reclassified from AOCL into earnings during the period of change.

Table of Contents
The following table summarizes the notional values and pretax impact of changes in the fair values of instruments designated as net investment hedges (in millions):

Notional Amount (Loss) Gain Recognized in AOCL
As of Three Months Ended March 31, 2025 Three Months Ended March 31, 2024
March 31, 2025 December 31, 2024
Cross-currency rate swaps 238.8  238.8  $ (9.4) $ 6.2 
Total 238.8  238.8  $ (9.4) $ 6.2 
During the fourth quarter of 2024, the Company amended one of the cross-currency rate swaps (notional amount of 123.2 million euros) to extend the maturity to December 31, 2025. The cross-currency rate swap was dedesignated from previous hedge accounting, and then redesignated as a net investment hedge, resulting in an immaterial off-market impact to the excluded interest component which will be recognized systematically into earnings over the life of the derivative.
The Company did not reclassify any gains or losses related to net investment hedges from AOCL into earnings during the three months ended March 31, 2025 and March 31, 2024, respectively. In addition, the Company did not have any ineffectiveness related to net investment hedges during the three months ended March 31, 2025 and 2024. The cash inflows and outflows associated with the Company’s derivative contracts designated as net investment hedges are classified as investing activities in the unaudited Condensed Consolidated Statements of Cash Flows.
17. Earnings (Loss) Per Share
A reconciliation of the numerator and denominator used in the calculation of basic and diluted loss per common share is as follows (in millions, except per share amounts):
Three Months Ended March 31, Three Months Ended March 31,
2025 2024
Net earnings (loss) attributable to Mirion Technologies, Inc. shareholders $ 0.3  $ (25.8)
Weighted average common shares outstanding — basic 225.655  199.729 
Effect of potentially dilutive securities — stock-based awards 1.263   
Weighted average common shares outstanding — diluted 226.918  199.729 
Net earnings (loss) per common share attributable to Mirion Technologies, Inc. — basic $   $ (0.13)
Net earnings (loss) per common share attributable to Mirion Technologies, Inc. — diluted $   $ (0.13)
Net earnings (loss) per share of common stock is computed using the two-class method required for multiple classes of common stock and participating securities based upon their respective rights to receive dividends as if all income for the period has been distributed. Basic earnings (loss) per share is computed by dividing earnings (loss) available to common stockholders by the weighted average number of common shares outstanding, adjusted for the outstanding non-vested shares. Diluted loss per share is computed by giving effect to all potentially dilutive securities outstanding for the period using the treasury stock method or the if-converted method based on the nature of such securities. For periods in which the Company reports net losses, diluted net loss per common share attributable to common stockholders is the same as basic net loss per common share attributable to common stockholders, because potentially dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. The Company incurred a net loss for the three months ended March 31, 2024; therefore, none of the potentially dilutive common shares were included in the diluted share calculations for those periods as they would have been anti-dilutive. The weighted average number of potentially dilutive common shares related to employee stock-based awards excluded as anti-dilutive for the three months ended March 31, 2024 were 2.577 million, respectively.

Table of Contents
The following classes of common stock were considered in the loss per share calculation.

Class A Common Stock
Holders of shares of our Class A common stock are entitled to one vote for each share held of record on all matters on which stockholders are entitled to vote generally, including the election or removal of directors. The holders of our Class A common stock do not have cumulative voting rights in the election of directors. Holders of shares of our Class A common stock are entitled to receive dividends when and if declared by the Company's Board of Directors out of funds legally available therefor, subject to any statutory or contractual restrictions on the payment of dividends and to any restrictions on the payment of dividends imposed by the terms of any outstanding preferred stock. Upon our liquidation, dissolution or winding up and after payment in full of all amounts required to be paid to creditors and to the holders of preferred stock having liquidation preferences, if any, the holders of shares of our Class A common stock will be entitled to receive pro rata our remaining assets available for distribution. Class A common stock issued and outstanding is included in the Company’s basic loss per share calculation, with the exception of founder shares discussed below.

Class B Common Stock
Holders of shares of our Class B common stock are entitled to one vote for each share held of record on all matters on which stockholders are entitled to vote generally, including the election or removal of directors. If at any time the ratio at which shares of IntermediateCo Class B common stock are redeemable or exchangeable for shares of our Class A common stock changes from one-for-one as the number of votes to which our Class B common stockholders are entitled will be adjusted accordingly. The holders of our Class B common stock do not have cumulative voting rights in the election of directors. Except for transfers to us or to certain permitted transferees set forth in the IntermediateCo certificate of incorporation, paired interests may not be sold, transferred or otherwise disposed of.

Holders of shares of our Class B common stock are not entitled to economic interests in us or to receive dividends or to receive a distribution upon our liquidation or winding up, but are "paired interests" with shares of IntermediateCo Class B common stock. If IntermediateCo makes distributions to us other than solely with respect to our Class A common stock, the holders of paired interests will be entitled to receive distributions pro rata in accordance with the percentages of their respective shares of IntermediateCo Class B common stock.

Our Class B common stock has voting rights but no economic interest in the Company and therefore are excluded from the calculation of basic and diluted earnings per share.

Warrants
As described above, during the three months ended March 31, 2024, the Company had outstanding warrants to purchase up to 27,249,779 shares of Class A common stock (including 18,749,779 Public Warrants and 8,500,000 Private Placement Warrants). One whole warrant entitled the holder thereof to purchase one share of Mirion Class A common stock at a price of $11.50 per share. The Company’s warrants were not included in the Company’s calculation of basic loss per share and were excluded from the calculation of diluted loss per share for the three months ended March 31, 2024, because their inclusion would have been anti-dilutive. During the second quarter of the year ended December 31, 2024, all warrants were exercised, redeemed, or exchanged for shares of Mirion Class A common stock or cash. Any shares of Mirion Class A common stock received are included in the calculation of basic and diluted earnings per share for the three months ended March 31, 2025.

Founder Shares
18,750,000 founder shares were subject to vesting in three equal tranches, based on the volume-weighted average price of our Class A common stock being greater than or equal to $12.00, $14.00 and $16.00 per share for any 20 trading days in any 30 consecutive trading day period. During the fourth quarter of the year ended December 31, 2024, all of the founder shares met the required vesting conditions, and the Class A common shares were considered outstanding for purposes of our earnings per share calculations for the three months ended March 31, 2025. Prior to the vesting, since the holders of the founder shares were not entitled to participate in earnings unless the vesting conditions were met, the founders shares were excluded from the calculation of our loss per share for the three months ended March 31, 2024.

Stock-Based Awards
Each stock-based award represents the right to receive a Class A common stock upon vesting of the awards. Per ASC 260, Earnings Per Share ("EPS"), shares issuable for little or no cash consideration upon the satisfaction of certain conditions (i.e., contingently issuable shares) should be included in the computation of basic EPS as of the date that all necessary conditions have been satisfied. As such, any stock-based awards such as RSUs that vest will be included in the Company's basic earnings (loss) per share calculations as of the date when all necessary conditions are met. We determine the potential dilutive effect of outstanding stock-based awards on EPS using the treasury stock method.

18. Noncontrolling Interests

On October 20, 2021, Mirion Technologies, Inc. consummated its previously announced Business Combination pursuant to the Business Combination Agreement.

Before the Closing of the Business Combination, the Sellers had the option to elect to have their equity consideration issued as either shares of Class A common stock or Paired Interests. The Sellers receiving shares of Class B common stock also received one share of IntermediateCo Class B common stock per share of Class B common stock as a Paired Interest. Each of the shares of Class A common stock and each Paired Interest were valued at $10.00 per share for purposes of determining the aggregate number of shares issued to the Sellers. Holders of shares of our Class B common stock are entitled to one vote for each share held of record on all matters on which stockholders are entitled to vote generally, including the election or removal of directors. If at any time the ratio at which shares of IntermediateCo Class B common stock are redeemable or exchangeable for shares of the Company’s our Class A common stock changes from one-for-one, as the number of votes to which our Class B common stockholders are entitled will be adjusted accordingly. The holders of our the Company’s Class B common stock do not have cumulative voting rights in the election of directors. Except for transfers to us or to certain permitted transferees set forth in the IntermediateCo certificate of incorporation, paired interests may not be sold, transferred or otherwise disposed of.

The holders of IntermediateCo Class B common stock have the right to require IntermediateCo to redeem all or a portion of their IntermediateCo Class B common stock for, at the Company’s election, (1) newly issued shares of the Company’s Class A common stock on a one-for-one basis or (2) a cash payment equal to the product of the number of shares of IntermediateCo Class B common stock subject to redemption and the arithmetic average of the closing stock prices for a share of the Company’s Class A common stock for each of three (3) consecutive full trading days ending on and including the last full trading day immediately prior to the date of redemption (subject to customary adjustments, including for stock splits, stock dividends and reclassifications). This redemption right became available upon the expiration of certain lockup restrictions on April 18, 2022.

At the Closing Date, the Company owned 100% of the voting shares (Class A) of IntermediateCo and approximately 96% of the non-voting Class B shares of IntermediateCo. The Company recognized noncontrolling interests for the 8,560,540 shares, representing approximately 4% of the non-voting Class B shares, of IntermediateCo that are not attributable to the Company. After the conversions in the current quarter, the Company recognized noncontrolling interests for the 6,372,385 shares, representing the 2.7% of the non-voting Class B shares of IntermediateCo, that are not attributable to the Company. All conversions through March 31, 2025, have been non-cash and on a one-for-one basis for Class A common stock.

As of March 31, 2025, noncontrolling interests of $52.9 million were reflected in the unaudited Condensed Consolidated Statements of Stockholders’ Equity.

19. Accumulated Other Comprehensive Loss
The components of accumulated other comprehensive loss, net of tax, consist of the following (in millions):
March 31, 2025 December 31, 2024
Cumulative foreign currency translation adjustment, net of tax $ (71.6) $ (93.6)
Unrealized gain on pension and postretirement benefit plans, net of tax 2.4  2.4

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
You should read the following discussion and analysis of Mirion’s financial condition and results of operations together with the unaudited Condensed Consolidated Financial Statements and related notes of Mirion Technologies, Inc. that are included elsewhere in this Quarterly Report on Form 10-Q as well as our audited consolidated financial statements and the notes related thereto for the year ended December 31, 2024 that are included in our Annual Report on Form 10-K. This discussion contains forward-looking statements based upon current expectations that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under the section entitled “Risk Factors” included in this Quarterly Report on Form 10-Q as well as our Annual Report on Form 10-K. Unless the context otherwise requires, references in this section to “we,” “us,” “our,” “Mirion” and “the Company” refer to the business and operations of Mirion Technologies, Inc. and its consolidated subsidiaries. Unless the context otherwise requires or unless otherwise specified, all dollar amounts in this section are in millions.
Overview
We are a global provider of products, services, and software that allow our customers to safely leverage the power of ionizing radiation for the greater good of humanity through critical applications in the medical, nuclear and defense markets, as well as laboratories, scientific research, analysis, and exploration.
We provide dosimetry solutions for monitoring the total amount of radiation medical staff members are exposed to over time, radiation therapy quality assurance solutions for calibrating and verifying imaging and treatment accuracy, and radionuclide therapy products for nuclear medicine applications such as shielding, product handling, and medical imaging furniture. We provide robust, field-ready personal radiation detection and identification equipment for defense applications and radiation detection and analysis tools for power plants, labs, and research applications. Nuclear power plant product offerings are used for the full nuclear power plant lifecycle including core detectors, essential measurement devices for new build, maintenance, decontamination and decommission, and equipment for monitoring and control during fuel dismantling and remote environmental monitoring.
We manage and report results of operations in two business segments: Medical and Nuclear & Safety.
Our revenues were $202.0 million for the three months ended March 31, 2025 and $192.6 million for the three months ended March 31, 2024, of which 34.0% and 34.7% were generated in the Medical segment for the three months ended March 31, 2025 and 2024, respectively, and 66.0% and 65.3% were generated in the Nuclear & Safety segment for the three months ended March 31, 2025 and 2024, respectively.
Backlog (representing committed but undelivered contracts and purchase orders) was $813.5 million and $811.9 million as of March 31, 2025, and December 31, 2024, respectively.
Key Factors Affecting Our Performance

We believe that our business and results of operations and financial condition may be impacted in the future by various trends, conditions and risks.

The following key factors affecting our performance have included, and we anticipate they will continue to affect our future results:
Nuclear end market trends—Growth and operating results in our Nuclear & Safety segment are impacted by:
Our products are installed at the vast majority of addressable active nuclear power reactors globally, creating full lifecycle sales opportunities. This installed base drives recurring revenue through replacement and service cycles associated with our offerings and the typical 40 to 80 year operating life cycle of a nuclear power plant ("NPP");
The emerging megatrends surrounding the power demands of data centers, cloud computing, and artificial intelligence that can be served by Nuclear;
Increased government and industry acceptance of Nuclear as (a) a clean energy source, and (b) a viable option for domestic energy production in efforts to rely less on international imports; and
Decisions by governments to build new power plants or decommission existing plants can positively and negatively impact our customer base.

35

Table of Contents
Medical end market trends—Growth and operating results in our Medical segment are impacted by:
Medical radiation therapy quality assurance (“RT QA”) growth driven by growing and aging population demographics, low penetration of RT QA technology in emerging markets, and increased adoption of advanced software and hardware solutions for improved outcomes and administrative and labor efficiencies;
Changes to global regulatory standards, including new or expanded standards;
Increased focus on healthcare safety;
Medical/lab dosimetry growth supported by growing and aging demographics, increased number of healthcare professionals, and penetration of radiation therapy/diagnostics;
Changes to healthcare reimbursement; and
Potential budget constraints in hospitals and other healthcare providers.
Nuclear new build projects—A portion of our remaining performance obligations is driven by contracts associated with the construction of new nuclear power plants. These contracts can be long-term in nature and provide us with a strong pipeline for the recognition of future revenues in our Nuclear & Safety segment. We perform our services and provide our products at a fixed price for certain contracts. Fixed-price contracts carry inherent risks, including risks of losses from underestimating costs, operational difficulties and other changes that may occur over the contract period. If our cost estimates for a contract are inaccurate or if we do not execute the contract within our cost estimates, we may incur losses or the contract may not be as profitable as we expected. In addition, even though some of our longer-term contracts contain price escalation provisions, such provisions may not fully provide for cost increases, whether from inflation, the cost of goods and services to be delivered under such contracts or otherwise.
Geopolitical and Trade Conditions—Geopolitical and trade conditions, including related to matters affecting Russia, the relationship between the United States and China, and conflict in the Middle East has impacted and may continue to impact us, through increased inflation, limited availability of certain commodities, supply chain disruption, disruptions to our global technology infrastructure, including cyberattacks, increased terrorist activities, volatility or disruption in the capital markets, and delays or cancellations of customer projects.
Inflation and Interest Rates—We continue to actively monitor, evaluate and respond to developments relating to operational challenges in the current inflationary environment. Global supply chain disruptions and the higher inflationary environment remain unpredictable and our past results may not be indicative of future performance. In addition, the increase in interest rates has in turn led to increases in the interest rates applicable to our indebtedness and increased our debt service costs.
Tariffs or Sanctions—The United States imposed additional tariffs on imports from China and proposed new tariffs on imports from other countries, which has resulted in retaliatory tariffs and restrictions implemented by China and other countries and may result in additional tariffs and restrictions. There are, at any given time, a multitude of ongoing or threatened armed conflicts around the world. As one example, sanctions by the United States, the European Union, and other countries against Russian entities or individuals related to the Russia-Ukraine conflict, along with any Russian retaliatory measures could increase our costs, adversely affect our operations, or impact our ability to meet existing contractual obligations.
Strategic transactions—A large driver of our historical growth has been the acquisition and integration of related businesses. Our ability to integrate, restructure, and leverage synergies of these businesses will impact our operating results over time. From time to time we also divest businesses which could also impact our operating results.
Environmental objectives of governments—Growth and operating results in our Nuclear & Safety segment are impacted by environmental policy decisions made by governments in the countries where we operate. Our nuclear power customers may benefit from decarbonization efforts given the relatively low carbon footprint of nuclear power to other existing energy sources.
Government budgets—While we believe that we are poised for growth from governmental customers in both of our segments, our revenues and cash flows from government customers are influenced, particularly in the short-term, by budgetary cycles. This impact can be either positive or negative.
Research and development—A portion of our operating expenses is associated with research and development activities associated with the design of new products. Given the specific design and application of these products, there is some risk that these costs will not result in successful products in the market. Further, the timing of these products can move and be challenging to predict.
Financial risks—Our business and financial statements can be adversely affected by foreign currency exchange rates, changes in interest rates, recognition of impairment charges for our goodwill or other intangible assets and fluctuations in the cost and availability of commodities.

36

Table of Contents
Global risk, including tariffs—Our business depends in part on operations and sales outside the United States. Risks related to those international operations and sales include new foreign investment laws, new export/import regulations, and additional trade restrictions (such as tariffs, sanctions, and embargoes). New laws that favor local competitors could prevent our ability to compete outside the United States. Additional potential issues are associated with the impact of these same risks on our suppliers and customers. If our customers or suppliers are impacted by these risk factors, we may see the reduction or cancellation of customer orders, or interruptions in the supply of raw materials and components.
Tax risks—Our business and financial statements can be adversely affected by changes in tax rates or exposure to tax liabilities/assessments:
Our effective tax rate could be impacted by changes in tax laws;
Audits or assessments by tax authorities could result in additional tax payments for prior periods;
Foreign remittance taxes have not been provided on undistributed earnings of certain of our non-U.S. subsidiaries to the extent such earnings are considered to be indefinitely reinvested in operations. Changes in our intentions regarding reinvestment of such earnings could impact our income tax provision, cash taxes paid and effective tax rate; and
The OECD (Organisation for Economic Co-operation and Development) has proposed a global minimum tax of 15% of reported profits (Pillar Two) and many countries have incorporated Pillar Two model rule concepts into their domestic laws. Pillar Two legislation is effective for the Company for the year ended December 31, 2025. Although the model rules provide a framework for applying the minimum tax, countries may enact Pillar Two slightly differently than the model rules and on different timelines. While we expect the impact to be immaterial, Pillar Two could impact our cash taxes paid and effective tax rate.

The Board has overall oversight responsibility for our risk management. During 2024, the Company initiated a formal Enterprise Risk Management program ("ERM") where management and Internal Audit provide updates to the Board. These discussions include identification and scoring of key business risks and management's plans and progress to address identified focus areas.
Non-GAAP Financial Measures

We report our financial results in accordance with generally accepted accounting principles in the United States. (“GAAP”). However, management believes certain non-GAAP financial measures provide investors and other users with additional meaningful information that should be considered when assessing our ongoing performance. Management also uses these non-GAAP financial measures in making financial, operating, and planning decisions, and in evaluating our performance. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, our GAAP results. The non-GAAP financial measures we present may differ from similarly captioned measures presented by other companies. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures, and not to rely on any single financial measure to evaluate our business.

In particular, we use the non-GAAP financial measures “EBITA,” “EBITDA,” and “Adjusted EBITDA." "Adjusted EBITDA" is used in the calculation of the First Lien Net Leverage Ratio in the 2021 Credit Agreement described in Note 8, Borrowings, to the unaudited Condensed Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q.

Our Business Segments
We manage and report our business in two business segments: Medical and Nuclear & Safety.
Medical includes products and services for radiation therapy, nuclear medicine and personal dosimetry. This segment’s principal product offering is in Radiation Therapy Quality Assurance, which includes solutions for calibrating and/or verifying imaging, treatment machine, patient treatment plan, and patient treatment accuracy. The advancing field of Nuclear Medicine is also served by this segment including products for radiation measurement, product handling, and medical imaging, inclusive of software across the radiopharmaceutical lifecycle. Dosimetry solutions monitor the total amount of radiation medical staff members are exposed to over time.
Nuclear & Safety includes products and services focused on addressing critical radiation safety, measurement and analysis applications across nuclear energy, laboratories and research and other industrial markets such as defense. For NPPs, we sell products and services for use at any stage of their life (construction, operation, decommissioning and dismantling), with NPPs representing the majority of our sales into the nuclear end market.
Recent Developments
Russia and Ukraine
The United States, the European Union, the United Kingdom and other governments have implemented major trade and financial sanctions against Russia and related parties in response to Russia's invasion of Ukraine. We do business with Russian customers both within and outside of Russia and with customers who have contracts with Russian counterparties. The conflict’s impact on the Company is predominantly in our Nuclear & Safety segment. As of March 31, 2025, the Company has approximately $8.6 million in net contract assets and accounts receivable associated with Russian-related projects. We also maintain $12.9 million in advance payment guarantees and $13.0 million in performance guarantees in support of these projects. The remaining performance obligations in our backlog for Russian-related projects was approximately $112.7 million at March 31, 2025.

The Company will continue to monitor the social, political, regulatory and economic environment in Ukraine and Russia, and will consider actions as appropriate.

Tariffs

Starting in February 2025, the United States and other countries imposed and/or increased global tariffs on goods imported into, or exported from, the United States. While we generally execute an operational strategy of producing locally for most of our products, these tariffs and any future tariffs are expected to result in additional costs to the Company. Furthermore, due to the larger tariffs imposed between China and the United States, we anticipate a potential negative impact on China-related revenues. The current total estimated reduction in pre-tax earnings impact from the global tariffs (as currently in effect as of the date of this Quarterly Report on Form 10-Q) is approximately $2.0 million to $8.0 million for the rest of the fiscal year, after taking into account mitigating actions such as alternative sourcing strategies, production shifts, price increases and cost management. Furthermore, the announcement of the tariffs has had a significant impact on the foreign exchange rates between U.S. Dollar and other foreign currencies and could have a significant impact (positive or negative) on our future results of operations. The actual impact of the tariffs and secondary impacts to exchange rates may be significantly different than our current estimate. Our estimate is subject to several factors including the amount, duration, scope and nature of the tariffs, countermeasures that countries take, mitigating or other actions we take, and contractual implications.
Basis of Presentation
Financial information presented was derived from our historical consolidated financial statements and accounting records, and they reflect the historical financial position, results of operations and cash flows of the business in conformity with U.S. GAAP for financial statements and pursuant to the accounting and disclosure rules and regulations of the SEC. The consolidated financial statements include the accounts of the Company and its wholly owned and majority-owned or controlled subsidiaries. For consolidated subsidiaries where our ownership is less than 100%, the portion of the net income or loss allocable to noncontrolling interests is reported as “Income (loss) attributable to noncontrolling interests” in the unaudited Condensed Consolidated Statements of Operations. All intercompany accounts and transactions have been eliminated in consolidation.

Our Medical segment contributed $68.6 million and $66.8 million of revenues for the three months ended March 31, 2025 and 2024, respectively. Our Nuclear & Safety segment contributed $133.4 million and $125.8 million of revenues for the three months ended March 31, 2025 and 2024, respectively. Gross profit was $96.1 million and $87.1 million for the three months ended March 31, 2025 and 2024, respectively, resulting in a $9.0 million increase from the three months ended March 31, 2024.     
Net income was $0.4 million for the three months ended March 31, 2025 and our net loss was $26.5 million for the three months ended March 31, 2024. Our Medical segment contributed $6.7 million and $1.4 million of income from operations for the three months ended March 31, 2025 and 2024, respectively. Our Nuclear & Safety segment contributed $21.7 million and $12.6 million of income from operations for the three months ended March 31, 2025 and 2024, respectively. The overall decrease in net loss is primarily driven by a $5.7 million decrease in the loss from fair value of warrant liabilities in the prior year that no longer impacts the current year, increased revenues in the Nuclear & Safety segment, a favorable margin for current projects and products in the current period, and decreased amortization of intangible assets. Partially offsetting these items were higher software licensing costs, increased depreciation, and increased compensation costs in the current year.
Revenues
Revenues were $202.0 million for the three months ended March 31, 2025 and $192.6 million for the three months ended March 31, 2024. Revenues increased $9.4 million from the three months ended March 31, 2024.
Medical segment revenues increased for the three months ended March 31, 2025 compared with the three months ended March 31, 2024 primarily due to the recovery from delayed operations in the Nuclear Medicine ("NucMed") division in connection with a new ERP system implementation in 2024, increased domestic sales volume and pricing, partially offset by decreased revenues from the Asia-Pacific region, delayed operations from an ERP implementation in our RTQA business and reduced revenues from the exit of our lasers product line in the second half of 2024.

Table of Contents
Nuclear & Safety segment revenues increased for the three months ended March 31, 2025 compared with the three months ended March 31, 2024 primarily due to price increases and organic volume growth, partially offset by foreign exchange impacts.
Cost of revenues
Cost of revenues was $105.9 million for the three months ended March 31, 2025 and $105.5 million for the three months ended March 31, 2024, an increase of $0.4 million period over period.
Cost of revenues related to the Medical segment decreased $1.5 million period over period due to favorable margin on product mix. Cost of revenues related to the Nuclear & Safety segment increased $1.9 million period over period. The increase was primarily driven by organic volume growth.
Selling, general and administrative expenses
Selling, general and administrative (“SG&A”) expenses were $78.7 million for the three months ended March 31, 2025 and $84.1 million for the three months ended March 31, 2024, resulting in a decrease of $5.4 million period over period.
Our Medical segment incurred lower SG&A expenses of $2.2 million for the three months ended March 31, 2025 compared with the three months ended March 31, 2024. The decrease was primarily due to lower amortization expense, and lower mergers and acquisitions costs. Partially offsetting these savings were increased depreciation expense of newly capitalized assets and software expense for new ERP systems.
Our Nuclear & Safety segment incurred lower SG&A expenses of $3.9 million for the three months ended March 31, 2025 compared with the three months ended March 31, 2024. The decrease was driven by lower amortization expense related to intangible assets.

Corporate SG&A expenses were $17.7 million for the three months ended March 31, 2025 and $17.0 million for the three months ended March 31, 2024. The increase of $0.7 million was primarily driven by increased compensation costs.

Research and development
Research and development (“R&D”) expenses were $8.7 million for the three months ended March 31, 2025 and $7.9 million for the three months ended March 31, 2024, resulting in an increase of $0.8 million period over period. The increase in R&D expenses was primarily due to increased compensation costs and increased depreciation expense for the three months ended March 31, 2025 as compared to the three months ended March 31, 2024.
Income from operations
Income from operations was $8.7 million for the three months ended March 31, 2025 compared with a loss of $4.9 million for the three months ended March 31, 2024. On a segment basis, income from operations in the Medical segment for the three months ended March 31, 2025 and 2024 were $6.7 million and $1.4 million, respectively. Income from operations in the Nuclear & Safety segment for the three months ended March 31, 2025 and three months ended March 31, 2024 were $21.7 million and $12.6 million, respectively, representing an increase of $9.1 million period over period. Corporate expenses were $19.7 million and $18.9 million for the three months ended March 31, 2025 and 2024, respectively, representing a decrease in income from operations of $0.8 million as discussed in "Selling, general and administrative expenses" above. See “Business segments” and “Corporate and other” below for further details.
Interest expense, net
Interest expense, net, was $10.6 million for the three months ended March 31, 2025 and $13.8 million for the three months ended March 31, 2024. The decrease in interest expense, net was due to lower interest rates negotiated with the debt refinancing during the three months ended June 30, 2024, interest from derivatives, and additional interest earned on cash deposits in the current period. For more information, see Note 7, Borrowings, and Note 16, Derivatives and Hedging, to the unaudited Condensed Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q.

Foreign currency (gain) loss, net
We recorded a $2.8 million net gain for the three months ended March 31, 2025 and a $0.8 million net loss for the three months ended March 31, 2024 from foreign currency exchange. The change in foreign currency loss (gain), net is due primarily to fluctuations in European local currencies in relation to the U.S. dollar.
Change in fair value of warrant liabilities
We recognized an unrealized expense of $5.7 million for the three months ended March 31, 2024. During the three months ended June 30, 2024, we settled the Public Warrant and Private Placement Warrant liabilities in conjunction with the warrant redemption/exchange. See Note 1, Nature of Business and Summary of Significant Accounting Policies, and Note 15, Fair Value Measurements, to the unaudited Condensed Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q.
Income taxes
The effective income tax rate was 33.3% and (4.7)% for the three months ended March 31, 2025 and 2024, respectively. The difference in effective tax rate between the periods was primarily attributable to mix of earnings and the impact of valuation allowances.
The effective income tax rate differs from the U.S. statutory rate of 21% due primarily to U.S. federal income tax permanent differences and the impact of valuation allowances.
Business segments
The following provides detail for business segment results for the three months ended March 31, 2025 and 2024. Segment income from operations includes revenues of the segment less expenses that are directly related to those revenues but excludes certain charges to cost of revenues and SG&A expenses predominantly related to corporate costs, which are included in Corporate and Other in the table below. Interest expense, foreign currency loss (gain), net, and other expense (income), net, are not allocated to segments.

For reconciliations of segment revenues and operating (loss) income to our consolidated results, see Note 14, Segment Information, to the unaudited Condensed Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q.

Revenues $ 68.6  $ 66.8 
Income from operations $ 6.7  $ 1.4 
Income from operations as a % of revenues 9.8  % 2.1  %

Medical segment revenues increased for the three months ended March 31, 2025 compared with the three months ended March 31, 2024 primarily due to the recovery from delayed operations in the NucMed division caused by the focus on a new ERP system implementation in 2024 of $4.3 million, $1.9 million in domestic revenue volume growth, and $1.4 million of pricing increases partially offset by a reduction in revenues from Asia-Pacific countries of $2.0 million, $2.0 million less revenues due to delayed operations from an ERP implementation in our RTQA business, and $1.1 million from the discontinuation of the lasers product line.
Income from operations was $6.7 million and $1.4 million for the three months ended March 31, 2025 and 2024, respectively, representing a $5.3 million increase in income from operations period over period. The increase in income from operations period over period was largely due to a favorable margin product mix of $2.4 million, reduction in amortization expense of $2.0 million, increased revenues noted above and reduction of merger and acquisition costs in 2025 of $0.6 million. Partially offsetting the increase in income was an increase in ERP related expenses of $0.6 million.

Revenues $ 133.4  $ 125.8 
Income from operations $ 21.7  $ 12.6 
Income from operations as a % of revenues 16.3  % 10.0  %
Nuclear & Safety segment revenues increased for the three months ended March 31, 2025 compared with the three months ended March 31, 2024 primarily due to organic volume growth of $6.9 million and pricing of $2.2 million, partially offset by a $1.9 million foreign exchange impact.
Income from operations was $21.7 million and $12.6 million for the three months ended March 31, 2025 and 2024, respectively. Income from operations increased $9.1 million period over period driven primarily by the changes in revenues described above, $1.4 million higher net income due to a positive product mix from higher margin projects and products in the current year, and $4.0 million in lower amortization expenses due to fully amortized intangible assets.
Corporate and other
Corporate and other costs include costs associated with our corporate headquarters located in Georgia, as well as centralized global functions including Executive, Finance, Legal and Compliance, Human Resources, Technology, Strategy, and Marketing and other costs related to company-wide initiatives (e.g., Business Combination transaction expenses, merger and acquisition activities, restructuring and other initiatives).

Corporate and other costs were $19.7 million for the three months ended March 31, 2025 and $18.9 million for the three months ended March 31, 2024, which represents an increase of $0.8 million period over period. The increase versus the comparable period was predominantly driven by increased compensation costs.

For reconciliations of segment operating income and corporate and other costs to our consolidated results, see Note 14, Segment Information, to the unaudited Condensed Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q.
Liquidity and Capital Resources
Overview of Liquidity
Our primary future cash needs relate to working capital, operating activities, capital spending, strategic investments, and debt service.
Mirion management believes that net cash provided by operating activities, augmented by long-term debt arrangements, will provide adequate liquidity for the next 12 months of independent operations, as well as the resources necessary to invest for growth in existing businesses and manage its capital structure on a short- and long-term basis. Access to capital and availability of financing on acceptable terms in the future will be affected by many factors, including our credit rating, economic conditions, and the overall liquidity of capital markets. There can be no assurance of continued access to financing from the capital markets on acceptable terms or at all.

Table of Contents
At March 31, 2025 and December 31, 2024 we had $186.2 million and $175.6 million, respectively, in cash and cash equivalents, which include amounts held by entities outside of the United States of approximately $136.4 million and $131.9 million, respectively, primarily in Europe and Canada. Non-U.S. cash is generally available for repatriation without legal restrictions, subject to certain taxes, mainly withholding taxes. We are asserting indefinite reinvestment of cash for certain non-U.S. subsidiaries. The Company has alternative repatriation options other than dividends should the need arise. The 2021 Credit Agreement provides for up to $175.0 million of revolving borrowings. The amount available on the revolving facility under the 2021 Credit Agreement (as defined below) as of March 31, 2025 and December 31, 2024 was approximately $157.0 million and $72.1 million, respectively.
For more information on our long-term debt arrangements, lease commitments, and other commitments and contingencies, see Note 7, Borrowings, Note 8, Leased Assets, and Note 9, Commitments and Contingencies, respectively, of the unaudited Condensed Consolidated Financial Statements included elsewhere in this Quarterly Report Form 10-Q.
Debt Profile
2021 Credit Agreement
On the Closing Date, certain subsidiaries of the Company entered into a credit agreement (as it may be amended, restated, supplemented, or otherwise modified from time to time, the “2021 Credit Agreement”) with the lending institutions party thereto. The 2021 Credit Agreement refinanced and replaced an earlier credit facility (the "2019 Credit Facility").
The 2021 Credit Agreement provides for an $830.0 million senior secured first lien term loan facility and a $175.0 million (see amendment description in Revolving Line of Credit below) senior secured revolving facility (collectively, the “Credit Facilities”). Funds from the Credit Facilities are permitted to be used in connection with the Business Combination and related transactions to refinance the 2019 Credit Facility referred to above and for general corporate purposes. The term loan facility is scheduled to mature on October 20, 2028 and the revolving facility is scheduled to expire and mature on March 21, 2030 (subject to other terms and conditions). The agreement requires the payment of a commitment fee of 0.50% per annum for unused revolving commitments, subject to stepdowns to 0.375% per annum and 0.25% per annum upon the achievement of specified leverage ratios. Any outstanding letters of credit issued under the 2021 Credit Agreement reduce the availability under the revolving line of credit.
The 2021 Credit Agreement is secured by a first priority lien on the equity interests of the Parent Borrower owned by Holdings and substantially all of the assets (subject to customary exceptions) of the borrowers and the other guarantors thereunder. Interest with respect to the facilities is based on, at the option of the borrowers, (i) a customary base rate formula for borrowings in U.S. dollars or (ii) a floating rate formula based on LIBOR (with customary fallback provisions) for borrowings in U.S. dollars, a floating rate formula based on Euro Interbank Offered Rate ("EURIBOR") for borrowings in Euro or a floating rate formula based on SONIA for borrowings in Pounds Sterling, each as described in the 2021 Credit Agreement with respect to the applicable type of borrowing. The 2021 Credit Agreement includes fallback language that seeks to either facilitate an agreement with the Company's lenders on a replacement rate for LIBOR in the event of its discontinuance or that automatically replaces LIBOR with benchmark rates based upon the Secured Overnight Financing Rate ("SOFR") or other benchmark replacement rates upon certain triggering events (SOFR was adopted via agreement amendment in replacement of LIBOR in 2023).
The 2021 Credit Agreement contains customary representations and warranties as well as customary affirmative and negative covenants and events of default. The negative covenants include, among others and in each case subject to certain thresholds and exceptions, limitations on incurrence of liens, limitations on incurrence of indebtedness, limitations on making dividends and other distributions, limitations on engaging in asset sales, limitations on making investments, and a financial covenant that the “First Lien Net Leverage Ratio” (as defined in the 2021 Credit Agreement) as of the end of any fiscal quarter is not greater than 7.00 to 1.00 if on the last day of such fiscal quarter certain borrowings outstanding under the revolving credit facility exceed 40% of the total revolving credit commitments at such time. The covenants also contain limitations on the activities of Mirion IntermediateCo, Inc. as the “passive” holding company. If any of the events of default occur and are not cured or waived, any unpaid amounts under the 2021 Credit Agreement may be declared immediately due and payable, the revolving credit commitments may be terminated and remedies against the collateral may be exercised. Mirion IntermediateCo, Inc. was in compliance with all debt covenants on March 31, 2025 and December 31, 2024.

Term Loan - The term loan has a seven-year term (expiring October 2028) and bears interest at the greater of LIBOR (through June 30, 2023) / SOFR (subsequent to June 30, 2023 through May 21, 2024) or 0.50%, plus 2.75%. On May 22, 2024, the Company entered into Amendment No. 3 (the “Amendment”) to the Credit Agreement. The Amendment reduced the applicable margin rate on the term loans from 2.75% to 2.25% and reduced the credit spread based upon rate term to 0%, with other terms and conditions remaining consistent (effectively the existing loan was refinanced). The Amendment was accounted for prospectively as a debt modification in accordance with ASC 470-50, Debt—Modifications and Extinguishments. No further principal payments are due until the expiration of the term. The interest rate was 6.55% (with no spread rate based upon rate term) and 6.85% (including spread rate based upon rate term) as of March 31, 2025 and December 31, 2024, respectively. The Company paid no principal payments for the three months ended March 31, 2025 and for year ended December 31, 2024, yielding an outstanding balance of approximately $694.6 million as of March 31, 2025 and December 31, 2024.
Revolving Line of Credit - The revolving line of credit arrangement initially had a five-year term (expiring October 2026) and bore interest at the greater of LIBOR (through June 30, 2023) / SOFR (subsequent to June 30, 2023) or 0%, plus 2.25%. The terms of the revolving line of credit were amended on March 21, 2025, through Amendment No. 4 to the 2021 Credit Agreement. Under the new amendment, revolving credit commitments from lenders increased from $90.0 million to $175.0 million, and the maturity date extended to March 21, 2030, subject to a “springing” maturity date that is 91 days prior to the maturity date of the outstanding term loan under the 2021 Credit Agreement (but only to the extent the outstanding principal amount of the term loan exceeds $100.0 million on the date of determination, and a final stated maturity date that is earlier than 91 days after March 21, 2030).
The agreement requires the payment of a commitment fee of 0.25% per annum for unused commitments. Any outstanding letters of credit reduce the availability of the revolving line of credit. There was no outstanding balance under the arrangement as of March 31, 2025 and December 31, 2024. Additionally, the Company has standby letters of credit issued under its 2021 Credit Agreement that reduce the availability under the revolver of $18.0 million and $17.9 million for the periods ended March 31, 2025 and December 31, 2024, respectively. The amount available on the revolver as of March 31, 2025 and December 31, 2024 was approximately $157.0 million and $72.1 million, respectively.
Share Repurchase Program
In December 2024, we instituted a share repurchase program for up to $100 million of the currently outstanding shares of our Class A common stock, as approved by our Board of Directors and authorized until November 14, 2029. Under the share repurchase program, we intend to repurchase shares from time to time through open market purchases, privately negotiated transactions, block purchases and otherwise in accordance with applicable federal securities laws, including Rules 10b5-1 and 10b-18 of the Securities Exchange Act of 1934, as amended. We have repurchased 1.2 million shares under this program as of March 31, 2025.

Hedges
As a result of the Company’s European operations, we are exposed to fluctuations in exchange rates between the Euro and U.S. dollar (our functional currency). As such, we entered into cross-currency rate swaps during the year ended December 31, 2023, to manage currency risks related to foreign exchange in foreign operations. The Company is also subject to interest rate risk related to the Credit Facilities. As such, we entered into an interest rate swap (notional amount of $75.0 million) during the year ended December 31, 2024, to mitigate the risk of adverse changes in benchmark interest rates on the Company's future interest payments.
The interest rate swap is a derivative financial instrument that has been designated and qualifies as a cash flow hedge. The changes in the fair values of the cash flow hedge are recorded in accumulated other comprehensive loss (“AOCL”) and are reclassified into the line item in our unaudited Consolidated Statements of Operations in which the hedged items are recorded in the same period the hedged items affect earnings. The changes in the fair values of hedges that are determined to be ineffective are immediately reclassified from AOCL into earnings. During the three months ended March 31, 2025, the new interest rate swap resulted in a loss of $0.1 million recognized in other comprehensive income ("OCI"), respectively. Gains of $0.1 million were recognized in income through interest expense and reclassified from OCI during the same periods.
The cross-currency rate swaps are derivative financial instruments that have been designated and qualify as hedges of net investments in our foreign operations. Accordingly, the changes in the fair values of the swaps are recognized in net investment hedges adjustments, a component of AOCL, to offset the changes in the values of the net investments being hedged. Any ineffective portions of net investment hedges are reclassified from AOCL into earnings during the period of change. The following table summarizes the notional values and pretax impact of changes in the fair values of instruments designated as net investment hedges (in millions):

Notional Amount (Loss) Gain Recognized in AOCL
As of Three Months Ended March 31, 2025 Three Months Ended March 31, 2024
March 31, 2025 December 31, 2024
Cross-currency rate swaps 238.8  238.8  $ (9.4) $ 6.2 
Total 238.8  238.8  $ (9.4) $ 6.2

Net cash provided by operating activities was $35.6 million for the three months ended March 31, 2025 as compared to net cash provided by operating activities of $6.0 million for the three months ended March 31, 2024, representing an increase of $29.6 million. The change is primarily due to a decrease in net loss of $26.9 million, an increase of operating cash from net working capital of $16.3 million (primarily due to increased collections from accounts receivable and costs in excess of billings), a decrease of $5.1 million in depreciation and amortization, and a decrease of $5.7 million in the change in fair value of warrant liabilities (which were all redeemed in the second quarter of the year ended December 31, 2024).

Net Cash Used in Investing Activities
Net cash used in investing activities was $7.6 million for the three months ended March 31, 2025 versus $12.9 million for the three months ended March 31, 2024 representing a change of $5.3 million. The decrease in net cash used was driven primarily by a $4.3 million decrease in purchases of property, plant, equipment and badges.
Net Cash (Used in) Provided by Financing Activities

Net cash used in financing activities was $21.2 million during the three months ended March 31, 2025 versus cash provided by financing activities of $0.2 million during the three months ended March 31, 2024. The decrease of $21.4 million period over period primarily relates to the $18.6 million of gross proceeds used to purchase treasury stock and stock repurchased to satisfy tax withholding for vesting restricted stock units of approximately $1.9 million in the prior year.
Critical Accounting Policies and Estimates
Our consolidated financial statements are prepared in accordance with U.S. GAAP. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, costs and expenses and related disclosures. Such estimates are based on historical experience and on various other factors that management believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these judgments and estimates under different assumptions or conditions and any such differences may be material.
During the three months ended March 31, 2025, there were no material changes to our critical accounting policies and estimates from those described under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations-Critical Accounting Policies and Estimates” in our Annual Report on Form 10-K.

ITEM 4. CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Securities Exchange Act of 1934, as amended (the "Exchange Act") is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that material information required to be disclosed in our reports filed or submitted under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

As required by Rules 13a-15(e) and 15d-15(e) under the Exchange Act, our Chief Executive Officer and Chief Financial Officer carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of March 31, 2025. Based upon their evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of March 31, 2025, our disclosure controls and procedures (as defined in Rules 13a- 15(e) and 15d-15(e) under the Exchange Act) were effective.

Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgement in evaluating the cost-benefit relationship of possible controls and procedures.

Changes in Internal Control Over Financial Reporting

There were no changes to our internal control over financial reporting (as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) during the quarter ended March 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION
ITEM 1. LEGAL PROCEEDINGS
Due to the nature of our activities, we are at times subject to pending and threatened legal actions that arise out of the ordinary course of business. For information regarding legal proceedings and other claims in which we are involved, see Note 9, Commitments and Contingencies, to the unaudited Condensed Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q. The disposition of any such currently pending or threatened matters is not expected to have a material effect on our business, results of operations or financial condition. However, the results of legal actions cannot be predicted with certainty. Therefore, it is possible that our business, results of operations and financial condition could be materially adversely affected in any particular period by the unfavorable resolution of one or more legal actions. Regardless of the outcome, litigation can have an adverse impact on our business because of defense and settlement costs, diversion of management resources and other factors. In addition, the expense of litigation and the timing of this expense from period to period are difficult to estimate, subject to change and could adversely affect our consolidated financial statements.
ITEM 1A. RISK FACTORS
In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, "Item 1A. Risk Factors", in our Annual Report on Form 10-K for the year ended December 31, 2024, as further updated and supplemented below, which could materially affect our business, results of operations, and financial conditions. These risks are not the only risks facing our Company. Additional risks and uncertainties not currently known to us, or that we currently deem to be immaterial, could also materially adversely affect our business, financial condition or future results.
The Company's operating results may be impacted by the effects of, and changes in, worldwide economic conditions, international trade, tariffs and retaliatory countermeasures, export controls and other trade barriers, global trade wars or domestic preferences which could increase our costs and materially and adversely affect our business, results of operations and financial condition. Our global business, operations, and the execution of our business strategies and plans are subject to global competition and economic and geopolitical risks that are beyond our control, such as, among other things, tariffs and retaliatory countermeasures, trade barriers and other governmental protectionist measures impacting international trade agreements or imposing trade restrictions, any of which can negatively affect us.
The global economy has been impacted by geopolitical tensions. There is currently significant uncertainty about future trade relationships between the United States and various other countries, most significantly Russia, Canada, Mexico, China and the EU. Further escalation of specific trade tensions, including those between the U.S. and China, or more broadly in global trade conflicts, could materially and adversely affect the Company's business and operations. The U.S. government and other governments have imposed export controls and tariffs on certain products and certain components that we import into, and export out of, the United States, and we, our customers, suppliers, and partners may become subject to additional tariffs and export controls and our products and services may be subject to increased competition outside of the United States. In addition, geopolitical tensions could result in, among other things, cyberattacks, supply chain disruptions, higher energy and other commodity costs, lower demand, changes to foreign exchange rates and financial markets. Additional tariffs and trade restrictions may result in increased manufacturing costs and product pricing, further supply chain disruptions, limit access to end markets and lower profitability. We also generate a significant amount of our revenue outside of the United States which may be adversely affected by tariffs and trade controls imposed by other countries. Revenue generated from outside of North America accounted for approximately 37% of our net sales for the year ended December 31, 2024, and international sales are expected to remain a material percentage of our total revenue in future periods. If we are not successful in offsetting the impact of tariffs, export controls, trade barriers, and other geopolitical disruptions, our business revenue, gross margins, results of operations and financial condition may be adversely affected.
