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. 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.

On October 20, 2021 (the “Closing Date”), the Company, consummated its previously announced business combination (the “Business Combination”) pursuant to the certain business combination agreement (the "Business Combination Agreement"). As contemplated by the Business Combination Agreement, the Company became the corporate parent of Mirion Technologies TopCo., Ltd. ("Mirion TopCo"). In order to implement a structure similar to that of an “Up-C,” the Company established a Delaware corporation, Mirion IntermediateCo, Inc. (“IntermediateCo”), as a subsidiary of the Company.

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 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, 2022, 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 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 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. See Note 21, Noncontrolling Interests.


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. Refer to Note 16, 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: 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.
Significant Accounting Policies

There have been no material changes in our significant accounting policies during the nine months ended September 30, 2023, 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, 2022.
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 $7.5 million and $7.4 million as of September 30, 2023 and December 31, 2022, 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):
September 30, 2023 December 31, 2022
Prepaid insurance $ 0.4  $ 3.2 
Prepaid vendor deposits 4.4  5.1 
Prepaid software licenses 4.2  3.2 
Short-term marketable securities 5.0  4.3 
Income tax receivable and prepaid income taxes 1.4  2.8 
Other tax receivables 1.1  1.6 
Other current assets 15.5  13.4 
$ 32.0  $ 33.6 
Facility and Equipment Decommissioning Liabilities
The Company has asset retirement obligations (“ARO”) consisting primarily of equipment and facility decommissioning costs. ARO liabilities totaled $2.5 million for both periods ended September 30, 2023 and December 31, 2022, and were included in deferred income taxes and other liabilities on the Condensed Consolidated Balance Sheets. Accretion expense related to these liabilities was not material for any periods presented.
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 September 30, 2023 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 $798.8 million and $737.4 million as of September 30, 2023 and December 31, 2022, respectively. As of September 30, 2023, the Company expects to recognize approximately 23%, 36%, 17%, and 10% of the remaining performance obligations as revenue during the fiscal years 2023, 2024, 2025 and 2026, 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 16, Segment Information.
Warrant Liability

As of September 30, 2023, 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 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. See Note 17, Fair Value Measurements.
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 our 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 our 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
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. As of September 30, 2023 and December 31, 2022, no customer accounted for more than 10% of the accounts receivable balance.
Recent Accounting Pronouncements
In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-04 “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting”. ASU 2020-04 provides temporary optional expedients and exceptions for applying GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from the London Interbank Offered Rate ("LIBOR") and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate ("SOFR"). In December 2022, the FASB issued ASU 2022-06 to defer the sunset date of ASC 848 from December 31, 2022 to December 31, 2024, after which entities will no longer be permitted to apply the optional expedients in ASC 848.
The Company adopted ASC 848 on June 23, 2023 upon entry into Amendment No. 2 to the Company’s Credit Agreement to transition to SOFR, as further discussed in Note 9, Borrowings. The adoption of this standard did not have an impact on the condensed consolidated financial statements and related disclosures as the optional expedients under ASC 848 have allowed the Company to account for contract modifications as continuations of the existing contracts without further reassessments or remeasurements. Outstanding derivatives (see Note 18, Derivatives and Hedging) at the time of adoption were not impacted by the transition to SOFR.
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.
