Mirion Technologies, Inc. (“Mirion,” the “Company,” "Successor," "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. The Company provides products and services through 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 and medical imaging furniture. 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. In connection with the Business Combination, stockholders of GSAH elected to redeem 14,628,610 shares of Class A common stock, par value $0.0001 per share, of the Company (the “Class A common stock”), representing approximately 19.5% of the Company’s issued and outstanding Class A common stock before giving effect to the Business Combination.
GSAH was originally incorporated as a Delaware corporation on May 31, 2018 for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. GSAH units, each of which consisted of one share of Class A common stock and one fourth of one warrant were sold in GSAH's initial public offering on June 29, 2020. GSAH units, Class A common stock and warrants were listed on the New York Stock Exchange (the "NYSE") under the symbols, "GSAH.U", "GSAH" and "GSAH.WS", respectively. On the Closing Date, GSAH was renamed Mirion Technologies, Inc. Our Class A common stock and warrants are listed on the NYSE under the ticker symbols “MIR” and "MIR WS", respectively.
The aggregate business combination consideration (the “Business Combination Consideration”) paid by the Company to the selling shareholders of Mirion TopCo (the "Sellers") in connection with the consummation of the Business Combination was $1.3 billion in cash, 30,401,902 newly issued shares of Class A common stock and 8,560,540 newly issued shares of the Company’s Class B common stock that have voting rights but no economic interest in the Company, par value $0.0001 per share (the “Class B common stock” and, together with the Class A common stock, the “Common Stock”).
Basis of Presentation and Principles of Consolidation
The accompanying Consolidated Financial Statements and notes to 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"). 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 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 22, Noncontrolling Interest.
On October 20, 2021, the Company's Board of Directors determined to change Mirion TopCo's fiscal year end from June 30th of each year to December 31st of each year in order to align Mirion’s fiscal year end with GSAH’s fiscal year end.
Predecessor and Successor Reporting
The financial statements separate the Company’s presentation into two distinct periods. The period before the Closing Date of the Business Combination (the "Predecessor Period") depicts the financial statements of Mirion TopCo, and the period after the Closing (the "Successor Period") depicts the financial statements of the Company, including the consolidation of GSAH with Mirion Technologies, Inc.
The Business Combination was accounted for under Accounting Standards Codification ("ASC") 805, Business Combinations. GSAH was determined to be the accounting acquirer. Mirion Technologies, Inc. constituted a business in accordance with ASC 805 and the business combination constituted a change in control. Accordingly, the Business Combination was accounted for using the acquisition method. Under this method of accounting, Mirion TopCo was treated as the “acquired” company for financial reporting purposes and the acquired net assets were stated at fair value, with goodwill or other intangible assets recorded. Refer to Note 2, Business Combinations and Acquisitions, for further detail.
As a result of the application of the acquisition method of accounting in the Successor Period, the financial statements for the Successor Period are presented on a full step-up basis as a result of the Business Combination, and are therefore not comparable to the financial statements of the Predecessor Period.
Segments
The Company manages its operations through two operating and reportable segments: Medical and Technologies. 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 17, 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, tax valuation allowances and derivative warrant liabilities.
Cash and Cash Equivalents
The Company considers all cash on deposit and money market accounts purchased with original maturities of three months or less to be cash and cash equivalents. Cash equivalents primarily consist of amounts held in interest-bearing money market accounts that are readily convertible to cash. The Company maintains cash in bank deposit accounts that, at times, may exceed the insured limits of the local country, which may lead to a concentration of credit risk. Substantially all of the Company’s cash and cash equivalent balances were deposited with financial institutions which management has determined to be high-credit quality institutions. The Company has not experienced any losses in such accounts.
Restricted Cash
The Company maintains restricted cash and cash equivalent accounts with various financial institutions to support performance bonds with irrevocable letters of credit for contractual obligations to certain customers. As of December 31, 2023 and December 31, 2022, combined current and non-current restricted cash on the Consolidated Balance Sheets was $1.7 million and $1.5 million, respectively.
Accounts Receivable and Allowance for Doubtful Accounts
Accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is based on the Company’s assessment of the collectability of customer accounts. The Company regularly reviews the allowance by considering factors such as historical experience, credit quality, the age of the accounts receivable balances and current economic conditions that may affect a customer’s ability to pay. The allowance for doubtful accounts was $7.8 million and $7.4 million as of December 31, 2023 and December 31, 2022, respectively.
Inventories
Inventories are stated at the lower of cost or net realizable value. Cost is computed using actual costs or standard costs that approximate actual cost, determined on a first-in, first-out basis. A portion of the inventory relates to evaluation units located at customer locations to facilitate customer tests prior to purchasing. Inventories also include completed products and in-process customer projects for which the related revenue has been deferred pending delivery, completion of services or determination that all customer-specific acceptance criteria have been met. Inventory in excess of expected future demand or obsolete inventory is written down to its estimated realizable value based on future demand forecasts and historical demand trends.
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):
Lease Assets
The Company leases certain logistics, office, and manufacturing facilities, as well as vehicles, copiers and other equipment. We record our operating lease right of use ("ROU") assets and liabilities at the commencement date of the lease based on the present value of lease payments over the lease term.
ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Our leases may include options to extend or terminate the lease. These options to extend are included in the lease term when it is reasonably certain that we will exercise that option. While some leases provide for variable payments, they are not included in the ROU assets and liabilities because they are not based on an index or rate. Variable payments for real estate leases primarily relate to common area maintenance, insurance, taxes and utilities. Variable payments for equipment, vehicles and leases within supply agreements primarily relate to usage, repairs, and maintenance. As the implicit rate is not readily determinable for our leases, we apply a portfolio approach using an estimated incremental borrowing rate to determine the initial present value of lease payments over the lease terms on a collateralized basis over a similar term, which is based on market and company specific information. We use the unsecured
borrowing rate and risk-adjust that rate to approximate a collateralized rate, and apply the rate based on the currency of the lease, which is updated on a quarterly basis for measurement of new lease liabilities.
We have made an accounting policy election to not recognize ROU assets and liability for leases with a term of 12 months or less unless the lease includes an option to renew or purchase the underlying asset that are reasonably certain to be exercised. In addition, the Company has applied the practical expedient to account for the lease and non-lease components as a single lease component for all of the Company's leases.
See Note 10, Leased Assets for additional details.
Property, Plant, and Equipment
Property, plant, and equipment are carried at cost, net of accumulated depreciation and amortization. Property, plant and equipment acquired through the acquisition of a business are recorded at their estimated fair value at the date of acquisition. Depreciation is computed when an asset is placed into service using the straight-line method over the estimated useful life of the asset. Leasehold improvements are amortized using the straight-line method over the shorter of the related lease term or the estimated useful life of the improvements. Repair and maintenance costs are expensed as incurred.
The Company capitalizes costs incurred in the acquisition and development of software for both internal use software and externally-marketed software, including the costs of software, materials, consultants, and payroll-related costs of employees incurred in developing the computer software. Costs associated with externally-marketed software are expensed as incurred until technological feasibility has been established. Development costs related to internal-use software are amortized using the straight-line method over the shorter of the software license or the estimated useful life of the software. Costs associated with externally-marketed software are amortized equal to the greater of the amount computed using (i) the ratio that current gross revenue for a software product bears to the total of current and anticipated future revenue for that software product or (ii) the straight-line method over the remaining estimated economic life of the software product.
Estimated useful lives are periodically reviewed and, when appropriate, changes to estimates are made prospectively. When certain events or changes in operating conditions occur, asset lives may be adjusted, and an impairment assessment may be performed on the recoverability of the carrying amounts. Refer to Note 6, Property, Plant and Equipment, Net, for disclosure of estimated useful lives.
When property, plant equipment is retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the balance sheet. Any difference between the net asset value and the proceeds on sale are charged or credited to income.
Business Combinations
We account for business acquisitions in accordance with ASC 805, "Business Combinations". This standard requires the acquiring entity in a business combination to recognize all the assets acquired and liabilities assumed in the transaction and establishes the acquisition date fair value as the measurement objective for all assets acquired and liabilities assumed in a business combination. Certain provisions of this standard prescribe, among other things, the determination of acquisition date fair value of consideration paid in a business combination (including contingent consideration) and the exclusion of transaction and acquisition-related restructuring costs from acquisition accounting.
The determination of the fair value of assets acquired and liabilities assumed involves assessments of factors such as the expected future cash flows associated with individual assets and liabilities and appropriate discount rates at the closing date of the acquisition. For non-observable market values, the Company determines fair value using acceptable valuation principles (e.g., multiple excess earnings, relief from royalty and cost methods).
Results of operations for acquired companies are included in our consolidated results of operations from the date of acquisition.
Goodwill
Goodwill represents the excess of the purchase price paid over the estimated fair value of the net assets acquired and liabilities assumed in the acquisition of a business.
Goodwill has an indefinite useful life, and is not amortized, but instead tested for impairment annually as of October 1 or more often if events or changes in circumstances indicate that the carrying amount may exceed fair value as set forth in ASC 350, “Intangibles — Goodwill and Other.” The Company tests for goodwill impairment at the reporting unit level, which is an operating segment or one level below an operating segment. The amount of goodwill acquired in a business combination that is assigned to one or more reporting units as of the acquisition date is the excess of the purchase price of the acquired businesses (or portion thereof) included in the reporting unit, over the fair value assigned to the individual assets acquired or liabilities assumed from a market participant perspective. Goodwill is assigned to the reporting unit(s) expected to benefit from the synergies of the combination even though other assets or liabilities of the acquired entity may not be assigned to that reporting unit.
ASC 350 allows an optional qualitative assessment as part of annual impairment testing, prior to a quantitative assessment test, to determine whether it is more likely than not that the fair value of a reporting unit exceeds its carrying amount. If a qualitative assessment determines an impairment is more likely than not, the Company is required to perform a quantitative impairment test. Otherwise, no further analysis is required. Alternatively, the Company may elect to proceed directly to the quantitative impairment test.
In conducting a qualitative assessment, the Company analyzes actual and projected growth trends for net sales and margin for each reporting unit, as well as historical performance versus plan and the results of prior quantitative tests performed. Additionally, the Company assesses factors that may impact its business, including macroeconomic conditions and the related impact, market-related exposures, plans to market for sale all or a portion of the business, competitive changes, new or discontinued product lines, changes in key personnel, and any potential risks to projected financial results.
If performed, the quantitative test compares the fair value of a reporting unit with its carrying amount. We determine the fair value of each reporting unit by estimating the present value of expected future cash flows, discounted by the applicable discount rate, and/or peer company multiples. If the carrying value exceeds the fair value, the Company recognizes an impairment loss in the amount equal to the excess, not to exceed the total amount of goodwill allocated to that reporting unit.
The Company may reorganize its reporting unit structure to better align the Company's operations within its reporting unit structure. In such cases, the Company assesses and re-defines reporting units effective as of the reorganization date including reallocation of goodwill on a relative fair value basis as applicable to affected reporting units. Goodwill impairment analysis will be performed as of the effective reorganization date both before and after the reorganization to test for any goodwill impairment. Refer to Note 8, Goodwill and Intangible Assets, for further detail.
Intangible Assets
Intangible assets relate to the value associated with our developed technology, customer relationships, backlog, and trade names at the time of acquisition through business combinations.
The Company determined the fair value of intangible assets acquired through an income approach, using the excess earnings method for customer relationships and backlog. Under the excess earnings method, an intangible asset’s fair value is equal to the present value of the incremental after-tax cash flows attributable solely to the intangible asset over its remaining useful life. The relief from royalty method was used to determine the fair value of developed technology and trade name. The valuation models were based on estimates of future operating projections of the acquired business and rights to sell products as well as judgments on the discount rates used and other variables. We determined the forecasts based on a number of factors, including our best estimate of near-term net sales expectations and long-term projections, which include review of internal and independent market analyses. The discount rate used was representative of the weighted average cost of capital.
The customer relationships definite lived intangible assets are amortized using the double declining balance method with estimated useful lives ranging from 6 to 13 years, while all other definite lived intangible assets are amortized on a straight-line basis over their estimated useful lives, ranging from 5 to 16 years for developed technology and 1 to 10 years for trade names and other. The Company regularly evaluates the amortization period assigned to each intangible asset to ensure that there have not been any events or circumstances that warrant revised estimates of useful lives. Refer to Note 8, Goodwill and Intangible Assets, for further detail.
Impairment of Long-Lived Assets
The Company reviews long-lived assets and definite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If an evaluation of recoverability is
required, the estimated undiscounted future cash flows associated with the asset group are compared to the asset group’s carrying amount to determine if a write-down is required. If the undiscounted cash flows are less than the carrying amount, an impairment loss is recorded to the extent that the carrying amount exceeds the fair value. No impairment was recorded during any periods or fiscal years presented.
Facility and Equipment Decommissioning Liabilities
The Company has asset retirement obligations (“ARO”) consisting primarily of equipment and facility decommissioning costs. The estimated fair value of these ARO liabilities is recognized in the period in which the liability is generated and a corresponding increase to the carrying value of the related asset is recorded and depreciated over the useful life of the asset. The Company’s estimates of its ultimate AROs could change because of changes in regulations, the extent of environmental remediation required, the means of reclamation, cost estimates, exit or disposal activities or time period estimates.
ARO liabilities totaled $2.3 million and $2.5 million at December 31, 2023 and December 31, 2022, respectively, and were included in Other liabilities in the consolidated balance sheets. Accretion expense related to these liabilities was not material for any periods presented.
Product Warranty
The Company offers warranties against material defects for most of its products for a specified time period, usually to twenty-four months from delivery or acceptance. When the related revenues are recognized, the Company provides for the estimated future costs of warranty obligations in cost of revenues. The accrued warranty costs represent the Company’s best estimate at the time of sale of the total costs that will be incurred to repair or replace product parts that fail while still under warranty.
The amount of the accrued estimated warranty cost obligations for established products is based on historical experience as to product failures adjusted for current information on repair costs. For new products, estimates include the historical experience of similar products, as well as a reasonable allowance for warranty expenses associated with the new products. On a quarterly basis, the Company reviews the accrued warranty costs and updates the historical warranty cost trends, if required.
Warrant Liability
As of December 31, 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 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 18, Fair Value Measurements.
Revenue Recognition
The Company recognizes revenue from arrangements that include performance obligations to design, engineer, manufacture, deliver, and install products. The Company identifies a performance obligation for each promise in a contract to transfer a distinct good or service to the customer. As part of its assessment, the Company considers all goods and/or services promised in the contract, regardless of whether they are explicitly stated or implied by customary business practices. The Company’s contracts may contain either a single performance obligation, including the promise to transfer individual goods or services that are not separately distinct within the context of the respective contracts, or multiple performance obligations. For contracts that contain multiple performance obligations, the Company allocates the consideration to which it expects to be entitled to each performance obligation based on relative standalone selling prices
and recognizes the related revenue when or as control of each individual performance obligation is transferred to customers. The Company does not assess whether promised goods or services are performance obligations if they are immaterial in the context of the contract with the customer. The Company combines multiple contracts entered into at or around the same time with a customer if the contracts are negotiated as a package with a single commercial objective, the consideration paid under the contracts depends on the price or performance of the other contract, or if the goods or services promised in the contracts are a single performance obligation. Service revenues (service-type warranty, post contract support, installation, and subscription-based services) are recognized over time as the customers receive and consume benefits of such services simultaneously. Assurance-type warranties guarantee that a product complies with agreed-upon specifications and accordingly are not separate performance obligations. A provision for these warranties is recognized in the period during which the associated revenue is recognized. In most cases, installation services represent a separate performance obligation. The customer simultaneously receives and consumes the benefits as the installation services are performed, as other entities could complete the installation at any point during the installation process. When the product and installation service are determined to be a combined performance obligation, revenue is recognized over time as the installation is performed and included in product revenue in the consolidated statement of operations.
Variable consideration such as rebates, sales discounts and sales returns are estimated and treated as a reduction of revenue in the same period the related revenue is recognized. These are estimated based on contractual terms, historical practices, and current trends, and are adjusted as new information becomes available. Revenues exclude any taxes that the Company collects from customers and remits to tax authorities. Amounts billed to customer for shipping and handling are included in revenue, while the related shipping and handling costs are reflected in cost of products in the period in which revenue is recognized. The Company has elected a practical expedient under ASC 606 that allows for shipping and handling activities that occur after the customer has obtained control of a good to be accounted for as a fulfillment cost. The Company does not adjust the promised amount of consideration for the effects of a significant financing component, if, at contract inception, the Company expects the period between the time when the Company transfers a promised good or service to the customer and the time when the customer pays for that good or service will be one year or less.
The Company exercises judgment in determining the timing of revenue by analyzing the point in time or the period over which the customer has the ability to direct the use of and obtain substantially all of the remaining benefits of the performance obligation. Typically, over-time revenue recognition is based on the utilization of the input measure of costs incurred to date relative to total estimated costs to measure progress. Changes in total estimated costs are recognized using the cumulative catch-up method of accounting which recognize the cumulative effect of the changes on current and prior periods in the current period. Accordingly, the effect of the changes on future periods of contract performance is recognized as if the revised estimate had been the original estimate. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are first determined. A significant change in an estimate on one or more contracts could have a material effect on the Company’s consolidated financial position, results from operations, or cash flows. However, there were no significant changes in estimated contract costs for the year ended December 31, 2023, the year ended December 31, 2022, the Successor Period of October 20, 2021 through December 31, 2021, the Predecessor Periods of July 1, 2021 through October 19, 2021, or the fiscal year ended June 30, 2021.
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.
Certain of the Company’s products are sold through distributors and third-party sales representatives under standard agreements whereby distributors purchase products from the Company and resell them to customers. These agreements give distributors the right to sell the Company’s products within certain territories and establish minimum order requirements. These arrangements do not provide stock rotation or price protection rights and do not contain extended payment terms. Rights of return are limited to repair or replacement of delivered products that are defective or fail to meet the Company’s published specifications. Provisions for these warranty costs are recognized in the same period that the related revenue is recorded similar to other assurance-type warranties.
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. Services are provided to the customer via passive dosimeter badges that the Company supplies to customer personnel. Depending on the type of badge utilized, either customers return the used badges to the Company for analysis, or they obtain the analysis directly via a self-service web portal. The Company believes that badge production, badge wearing, badge analysis and report preparation are not individually distinct and therefore a single performance obligation recognized over time. Revenue is recognized ratably over the service period as the service is continuous, and no other discernible pattern of recognition is evident. Many customers pay for these measuring and monitoring services in advance. The amounts are recorded as deferred contract revenue in the consolidated balance sheets and represent customer deposits invoiced in advance for services to be rendered over the service period, net of a reserve for estimated cancellations.
Payment terms for shipments to end-users are generally net 30 days. Payment terms for distributor shipments may range from 30 to 90 days. Service arrangements commonly call for payments in advance of performing the work (e.g., extended warranty and service contracts), upon completion of contract milestones (e.g., custom development manufacturing), or a combination of each.
The Company’s costs to obtain contracts are typically comprised of sales commissions. A majority of these costs relate to revenue that is recognized over a period that is less than one year. For costs related to revenue recognized over a period less than one year, the Company has elected the practical expedient under ASC 606 to expense these costs as incurred.
Contract Balances
Revenue earned in excess of billings on contracts in progress (contract assets) are classified in the consolidated balance sheet as a current asset and included in costs in excess of billings on uncompleted contracts. Amounts billed in excess of revenue earned (contract liabilities) are included in deferred contract revenue. For more information, see Note 4, Contracts in Progress.
Remaining Performance Obligations
The remaining performance obligations for all open contracts as of December 31, 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 $857.1 million and $737.4 million as of December 31, 2023 and December 31, 2022, respectively. As of December 31, 2023, the Company expects to recognize approximately 46%, 18%, 11%, and 8% of the remaining performance obligations as revenue during the fiscal years 2024, 2025, 2026 and 2027, 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 17, Segment Information.
Warrants
As described above, the Company has outstanding warrants to purchase up to 27,249,779 shares of Class A common stock. One whole warrant entitles 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 are not included in the Company’s calculation of basic loss per share and were excluded from the calculation of diluted loss per share because their inclusion would be anti-dilutive.
Founder Shares
Founder shares are shares of Class A common stock subject to certain vesting events and forfeiture if a required vesting event does not occur within five years of the closing of the Business Combination. The founder shares are subject to vesting in three equal tranches, based on the volume-weighted average price of the Class A common stock being greater than or equal to $12, $14 and $16 per share for any 20 trading days in any 30 consecutive trading day period. Holders of the founder shares are entitled to vote such founder shares and receive dividends and other distributions with respect to such founder shares prior to vesting, but such dividends and other distributions with respect to unvested founder shares will be set aside by the Company and shall only be paid to the holders of the founder shares upon the vesting of such founder shares.
As the holders of the founder shares are not entitled to participate in earnings unless the vesting conditions are met, the founders shares have been excluded from the calculation of basic earnings per share. The founders shares are also excluded from the calculation of diluted earnings per share because their inclusion would be anti-dilutive.
Predecessor Period
In the Predecessor Periods presented, the rights, including the liquidation, dividend rights, sharing of losses, and voting rights of the A Ordinary Shares and B Ordinary Shares of Mirion TopCo were identical. As the rights of both classes of shares were identical, the undistributed earnings are allocated on a proportionate basis and the resulting net loss per share attributed to common stockholders is therefore the same for A Ordinary Shares and B Ordinary Shares on an individual or combined basis.
The Company’s participating securities include the Company’s non-vested A Ordinary Shares, as the holders are entitled to non-forfeitable dividend rights in the event a dividend were paid on common stock. The holders of non-vested A Ordinary Shares did not have a contractual obligation to share in losses.
The rights, including the liquidation, dividend rights, sharing of losses, and voting rights of the A Ordinary Shares and B Ordinary Shares are identical. As the rights of both classes of shares were identical, the undistributed earnings were allocated on a proportionate basis and the resulting net loss per share attributed to common stockholders was therefore the same for A Ordinary Shares and B Ordinary Shares on an individual or combined basis.
Basic loss per share is computed by dividing loss available to shareholders 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 shareholders is the same as basic net loss per ordinary share attributable to shareholders, because potentially dilutive common shares are not assumed to have been issued if their effect is anti-dilutive.
Selling, General, and Administrative Expenses
The Company’s selling, general and administrative expenses consist of direct and indirect costs related to sales and corporate personnel, facilities, professional services, amortization of intangible assets, share-based compensation, and other operating activities.
Advertising Costs
Advertising costs, which the Company expenses when incurred, were approximately $1.3 million, $1.7 million, $0.4 million, $0.4 million, and $0.9 million for the fiscal year ended December 31, 2023, for the fiscal year ended December 31, 2022, the Successor Period from October 20, 2021 through December 31, 2021, the Predecessor Periods from July 1, 2021 through October 19, 2021 and the fiscal year ended June 30, 2021, respectively. Trade show costs were approximately $2.7 million, $2.8 million, $0.5 million, $0.7 million, and $0.3 million for the fiscal year ended December 31, 2023, December 31, 2022, Successor Period from October 20, 2021 through December 31, 2021, the Predecessor Periods from July 1, 2021 through October 19, 2021, and the fiscal year ended June 30, 2021, respectively.
Research and Development
Research and development expenses include costs of developing new products and processes, as well as non-project specific design and engineering costs. Research and development costs are expensed as incurred. Development costs related to software incorporated in the Company’s products are not material.
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 December 31, 2023 and December 31, 2022, no customer accounted for more than 10% of the accounts receivable balance.
Assets and Liabilities Held for Sale
We classify long-lived assets (disposal groups) as held for sale in the period when all of the following conditions have been met:
•We have approved and committed to a plan to sell the assets or disposal group;
•The asset or disposal group is available for immediate sale in its present condition;
•An active program to locate a buyer and other actions required to complete the sale have been initiated;
•The sale of the asset or disposal group is probable and expected to be completed within one year;
•The asset or disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and
•It is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.
We initially measure a long-lived asset (disposal group) that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a long-lived asset (disposal group) until the date of sale. We assess the fair value of a long-lived asset (disposal group) less any costs to sell each reporting period it remains classified as held for sale. A loss is recognized for any write-down to fair value less cost to sell. A gain is recognized for any subsequent increase in fair value less cost to sell, but not in excess of the cumulative loss previously recognized. Upon being classified as held for sale, we cease depreciation on depreciable assets.
Upon determining that a long-lived asset (disposal group) meets the criteria to be classified as held for sale, we report the assets and liabilities of the disposal group in our consolidated balance sheets as assets held for sale and liabilities held for sale, respectively. If the sale is expected to occur within the year and the proceeds will be used in the regular course of business (e.g., not being used to pay off long-term debt), the assets and liabilities held for sale are considered current. If the sale is not expected during the next year or the proceeds will be used to pay off long-term debt, the assets and liabilities held for sale are considered non-current.
Derivatives and Hedging
The Company uses derivatives to manage underlying commercial risks, including risks related to foreign exchange and interest rate. Accounting for derivatives as hedges requires that, at inception and over the term of the arrangement, the hedged item and related derivative meet the requirements for hedge accounting. In evaluating whether a particular relationship qualifies for hedge accounting, the Company tests effectiveness at inception and each reporting period thereafter by determining whether changes in the fair value of the derivative offset, within a specified range, changes in the fair value of the hedged item. If fair value changes fail this test, the Company discontinues applying hedge accounting to that relationship prospectively. Fair values of both the derivative instrument and the hedged item are calculated using internal valuation models incorporating market-based assumptions, subject to third-party confirmation, as applicable.
The changes in the fair values of derivatives that have been designated and qualify as cash flow hedges or hedges of net investments in foreign operations are recorded in accumulated other comprehensive loss ("AOCL") and are reclassified into the line item in our consolidated statement of income in which the hedged items are recorded in the same period the hedged items affect earnings. The changes in the fair values of derivatives that were not designated and/or did not qualify as hedging instruments are immediately recognized in earnings.
The Interest Rate Swap and Cross-Currency Rate Swaps the Company entered into are not exchange traded instruments and their fair value is determined using the cash flows of the swap contracts, discount rates to account for the passage of time, USD-SOFR CME term, current foreign exchange market data and credit risk, which are all based on inputs readily available in public markets and categorized as Level 2 fair value hierarchy measurements. Refer to Note 18, Fair Value Measurement, and Note 19, Derivatives and Hedging, for further details.
Stock-Based Compensation Awards
The Company adopted and obtained stockholder approval at its special meeting of the stockholders on October 19, 2021 of the 2021 Omnibus Incentive Plan (the “2021 Plan”). 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. The 2021 Plan is an omnibus plan that may provide these incentives through grant of stock options, stock appreciation rights, restricted stock, restricted stock units, performance awards, other cash-based awards and other stock-based awards to employees, directors, or consultants of the Company. See Note 15, Stock-based Compensation, for further information on this plan.
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. During the Successor Period, the Company uses various forms of long-term incentives including, but not limited to Restricted Stock Units (“RSUs”) and Performance-based RSUs (“PSUs”), provided that the issuance of such stock options was contingent upon the Company filing a registration statement on Form S-8 with the SEC, which occurred on December 27, 2021. The grant date fair value of the PSUs is determined using a Monte Carlo simulation model. The grant date fair value of the RSUs is determined using the closing
price of the Company’s Class A common stock price on the day before the grant date. 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.
In conjunction with entering into the Business Combination Agreement, on June 17, 2021 the Sponsor issued membership interests to certain Mirion employees and the current Chairman of the Board of Mirion (collectively, the "Profits Interests"). The Profits Interests are subject to service and performance vesting conditions and do not fully vest until all of the applicable conditions are satisfied. In addition, the Profits Interests are subject to certain forfeiture conditions. Accordingly, these awards have been treated as stock based compensation under ASC 718. The grant date fair value of the Profits Interests is based upon a valuation model using Monte Carlo simulations. As the Profits Interests included the completion of the Business Combination as a vesting condition, the expense that accumulated prior to the Business Combination was recorded on the last day of the Predecessor Period and the remainder is recorded over the future vesting period.
Prior to the Business Combination, the Company accounted for share-based compensation related to restricted stock awards granted to certain employees by recognizing the grant date fair value of the awards over the requisite service period, which is equal to the vesting period. The Company had the option to buy back the unvested awards upon termination of employment at the lesser of the original issuance price paid by employees or the fair value of the shares on the buy-back date. The Company estimated the value of the restricted stock awards by using the Black-Scholes option valuation model, which requires the use of certain subjective assumptions. Significant assumptions include management’s estimates of the estimated stock price volatility, the expected life of the awards and related employee forfeiture rates.
For more information see Note 15, Stock-based Compensation.
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 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 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.
Accounting for Income Taxes
The Company accounts for income taxes and the related accounts under the asset and liability method. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax bases of assets and liabilities and their reported amounts. Valuation allowances are recorded to reduce deferred tax assets to the amount that will more likely than not be realized. The Company classifies all deferred tax assets and liabilities, and any related valuation allowance, as non-current in the Consolidated Balance Sheets.
The Company accounts for uncertainty in income taxes using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. The Company classifies the liability for unrecognized tax benefits as current in the balance sheet, to the extent that the Company anticipates payment or receipt of cash within one year. Interest and penalties related to uncertain tax positions are recognized in the provision for income taxes.
Defined Benefit Pension Plans and Other Employee Benefits
The Company has defined benefit pension plans that cover certain of its employees in France, Japan, and Germany. The Company also has a post-retirement plan that provides for the reimbursement of a portion of medical and life insurance premiums for certain retirees and eligible dependents in the United States. Plan liabilities are revalued annually based on assumptions relating to the discount rates used to measure future obligations and expenses, salary-scale inflation rates,
mortality and other assumptions. The selection of assumptions is based on historical trends and known economic and market conditions at the time of valuation; however, actual results may differ from the Company’s estimates.
Foreign Currency Translation
Local currency is the functional currency for substantially all of the Company’s foreign operations. Assets and liabilities of foreign operations are translated into U.S. dollars using the exchange rates in effect at the balance sheet reporting date, while income and expenses are translated at the average monthly exchange rates during the period. We record gains and losses from the translation of financial statements in foreign currencies into U.S. dollars in other comprehensive income. The income tax effect of currency translation adjustments related to foreign subsidiaries that are not considered indefinitely reinvested is recorded as a component of deferred taxes with an offset to other comprehensive income. We record gains and losses from changes in exchange rates on transactions denominated in currencies other than each reporting location’s functional currency in the consolidated statements of operations for each period.
Loss Per Share
Net 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 loss per share is computed by dividing 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.
Successor Period
Upon the closing of the Business Combination, the following classes of 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 our Board 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.
Class B Common Stock
Holders of shares of our Class B common stock also hold shares of IntermediateCo Class B common stock on a one-to-one basis (the "paired interests"). 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 a one-for-one basis, 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 pursuant to the IntermediateCo Charter or to certain permitted transferees set forth in our Charter, the shares of our Class B common stock and corresponding shares of IntermediateCo Class B common stock 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. However, if IntermediateCo makes distributions to us other than solely with respect to our Class A common stock, the holders of shares of IntermediateCo Class B common stock will be entitled to receive distributions pro rata in accordance with the percentages of their respective shares of IntermediateCo Class B common stock.
Our shares of Class B common stock are excluded from the calculation of basic and diluted earnings per share because such shares have voting rights but no economic interest in the Company.
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 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 19, 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.
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 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.
