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) 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, medical imaging furniture, and rehabilitation products. The Technologies 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, and Japan.
Basis of Presentation and Principles of Consolidation
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, 2023, 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 IntermediateCo that is not attributable to the Company.
Segments
Segments
The Company manages its operations through two operating and reportable segments: Medical and Technologies (formerly known as Industrial). 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.
Use of Estimates
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: business combinations, goodwill and intangible assets; estimated progress toward completion for certain revenue contracts; uncertain tax positions and tax valuation allowances and derivative warrant liabilities.
Accounts Receivable and Allowance for Doubtful Accounts
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.
Prepaid Expenses and Other Current Assets
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.
Facility and Equipment Decommissioning Liabilities
Facility and Equipment Decommissioning Liabilities
The Company has asset retirement obligations (“ARO”) consisting primarily of equipment and facility decommissioning costs. ARO liabilities totaled $2.3 million for both periods ended March 31, 2024 and December 31, 2023, and were included in accrued expenses and other current liabilities and other liabilities on the unaudited Condensed Consolidated Balance Sheets. Accretion expense related to these liabilities was not material for any periods presented.
Revenue Recognition
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 4, Contracts in Progress for further details.
Remaining Performance Obligations
The remaining performance obligations for all open contracts as of March 31, 2024 include assembly, delivery, installation, and trainings. The aggregate amount of the transaction price allocated to the remaining performance obligations for all open customer contracts
Warrant Liability
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 accounts for the warrants in accordance with the guidance contained in ASC 815, “Derivatives and Hedging”, under which the warrants do not meet the criteria for equity treatment and must be recorded as derivative liabilities. Accordingly, the Company classifies the warrants as liabilities at their fair value and adjusts the warrants to fair value at each reporting period. This liability is subject to re-measurement at each balance sheet date until the warrants are exercised or expire, and any change in fair value is 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 has 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") to GS Sponsor II LLC, the sponsor of GSAH (the "Sponsor"), to anyone who is 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 is equivalent to that of each Public Warrant. The determination of the fair value of the warrant liability may be subject to change as more current information becomes available and accordingly the actual results could differ significantly. Derivative warrant liabilities are classified as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities.
Treasury Stock
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.
If the treasury shares are ever reissued in the future at a price higher than its 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 there are previously recorded gains 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. If treasury stock is reissued in the future, a cost flow assumption (e.g., FIFO, LIFO or specific identification) will be adopted to compute excesses and deficiencies upon subsequent share reissuance.
Concentrations of Risk
Concentrations of Risk
Financial instruments that are potentially subject to concentration of credit risk consist primarily of cash and 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.
Recent Accounting Pronouncements
Recent Accounting Pronouncements
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 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. For all entities, the amendments will be effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments will be applied retrospectively to all prior periods presented in the financial statements. 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.

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 March 2024, the FASB issued ASU 2024-01 "Compensation - Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards". ASU 2024-01 improves GAAP by demonstrating how an entity should apply the scope guidance to determine whether profits interest and similar awards should be accounted for in accordance with Topic 718. For public business entities, the amendments are effective for annual periods beginning after December 15, 2024, and interim periods within those annual periods. Early adoption is permitted for both interim and annual financial
statements that have not yet been issued or made available for issuance. The amendments should be applied either (1) retrospectively to all prior periods presented in the financial statements or (2) prospectively to profits interest and similar awards granted or modified on or after the date at which the entity first applies the amendments. The Company is currently evaluating the impact of this ASU.
Other Guidance Issued But Not Yet Adopted
In March 2024, the SEC issued its final climate disclosure rules, which require the disclosure of climate-related information in annual reports and registration statements. The rules require disclosure in the audited financial statements of certain effects of severe weather events and other natural conditions above certain financial thresholds, as well as amounts related to carbon offsets and renewable energy credits or certificates, if material. Disclosure requirements will begin phasing in for fiscal years beginning on or after January 1, 2025. On April 4, 2024, the SEC determined to voluntarily stay the final rules pending certain legal challenges. We are currently evaluating the impact of the new rules and considering the potential outcome of the legal challenges.
