Basis of Presentation and Principles of Consolidation

The unaudited interim condensed consolidated financial statements were prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) for interim financial information; therefore, as permitted under these rules, certain footnotes and other financial information included in audited financial statements were condensed or omitted. The interim financial statements presented include all adjustments, which are of a normal and recurring nature, necessary for a fair presentation of the results for such periods. Results for these interim periods are not necessarily indicative of full year results.

The unaudited interim condensed consolidated financial statements should be read in conjunction with the audited financial statements of Mirion TopCo as of and for the year ended June 30, 2021, and the notes related thereto. The unaudited interim condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Related-Party Transactions

On October 20, 2021 (the “Closing Date”), the Company consummated its previously announced business combination (the “Business Combination”) pursuant to the business combination agreement dated June 17, 2021 (as amended, the “Business Combination Agreement”) with GS Acquisition Holdings Corp II (“GSAH”). In connection with the Business Combination, GSAH changed its name to Mirion Technologies, Inc.

See Note 15 for subsequent events disclosure.

Prior to October 20, 2021, the Company entered into agreements with its historical primary investor, Charterhouse Capital Partners LLP (“CCP”), which obligated the Company to pay quarterly management fees of $0.1 million in total per year. In return, CCP provided various investment banking services relating to financing arrangements, mergers and acquisitions and other services. There were no material fees or expense reimbursements made to CCP during the three-month periods ended September 30, 2021, and September 30, 2020.

See Note 8 for notes payable to related parties.

Restructuring Costs

The Company periodically initiates restructuring activities in connection with certain acquisitions. The costs associated with restructuring actions are recorded in accordance with ASC 420, Exit or Disposal Cost Obligations, and include property, plant and equipment costs, severance and employee costs, professional fees, and other costs. Liabilities for costs associated with an exit or disposal activity are recognized in the period in which the liability is incurred. Restructuring liabilities are included in accrued expenses and other current liabilities in the Company’s Consolidated Balance Sheet. Charges associated with restructuring actions are recorded in Cost of Revenue and Selling, General, and Administrative Expenses in the Company’s Condensed Consolidated Statement of Operations and are accounted for separate from acquisition costs.

Recent Accounting Pronouncements

Accounting Guidance Issued But Not Yet Adopted

In March 2020, the FASB issued 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 LIBOR and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate. For all entities, ASU 2020-04 can be adopted after its issuance date through December 31, 2022. The Company is currently evaluating the impact of this ASU.

7

Recently Adopted Accounting Guidance

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”). ASU 2018-13 eliminates, adds and modifies certain disclosure requirements for fair value measurements as part of the FASB’s disclosure framework project. For all entities, ASU 2018-13 is effective for annual and interim reporting periods beginning after December 15, 2019. Certain amendments must be applied prospectively while others are to be applied on a retrospective basis to all periods presented. The Company adopted this guidance as of July 1, 2020, and it did not have a material impact on our consolidated financial statements or related disclosures.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaced the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For trade and other receivables, loans, and other financial instruments, we will be required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. Credit losses relating to available-for-sale debt securities will also be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. Application of the amendments is through a cumulative-effect adjustment to retained earnings as of the effective date. The Company adopted this guidance as of July 1, 2021, prospectively, which did not have a material impact on our consolidated financial statements.

In August 2018, the FASB issued ASU 2018-15, Intangibles – Goodwill and Other – Internal Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract, which amend the accounting for implementation, setup and other upfront costs for entities that are a customer in a hosting arrangement that is a service contract. ASU 2018-15 was effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. For all other entities, including emerging growth companies, the amendments are effective for fiscal years beginning after December 15, 2020, and interim periods within fiscal years beginning after December 15, 2021. Early adoption is permitted, including adoption in any interim period for which financial statements have not been issued. Application of the amendments can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company adopted this guidance as of July 1, 2021, prospectively, which did not have a material impact on our consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which, among other things, requires an entity to recognize a right-of-use asset and a lease liability on the balance for substantially all leases, including operating leases. Expanded disclosures with additional qualitative and quantitative information are also required. ASC 2016-02 and its related amendments were effective for public companies with interim and annual reporting periods beginning after December 15, 2018, and for non-public companies, including emerging growth companies, with interim and annual reporting periods beginning after December 15, 2021. Early adoption was permitted.

The Company adopted ASU 2016-02 and its amendments as of July 1, 2021, using the modified retrospective method and under such method no recast of prior-period financial statements was presented. The Company elected the package of practical expedients permitted under the transition guidance, which allowed the Company to carryforward its historical assessments of: (1) whether contracts are or contain leases, (2) lease classification and (3) initial direct costs. In addition, the Company did not elect the hindsight practical expedient to determine the reasonably certain lease term for existing leases. The Company elected a policy of not applying the recognition requirements to leases with a term of less than twelve months. The Company elected to account for lease and non-lease components as a combined single lease component.

8

The Company’s adoption of the standard resulted in a cumulative-effect adjustment to decrease retained earnings by $2.9 million, net of taxes, as of July 1, 2021. The standard did not materially impact the Company’s consolidated net income or liquidity and did not have an impact on debt-covenant compliance under the Company’s current debt agreements.

2. Acquisitions

The Company continually evaluates potential acquisitions that strategically fit with the Company’s existing portfolio and as a result, the Company completed one acquisition during the three months ended September 30, 2021 and one acquisition during the three months ended September 30, 2020.

All acquisitions are accounted for under the acquisition method of accounting, and the related assets acquired, and liabilities assumed are recorded at fair value. The Company makes an initial allocation of the purchase price at the date of acquisition based upon its understanding of the fair value of the acquired assets and assumed liabilities. The Company obtains the information used for the purchase price allocation during due diligence and through other sources. In the months after closing, as the Company obtains additional information about the acquired assets and liabilities, including through tangible and intangible asset appraisals, and learns more about the newly acquired business, it is able to refine the estimates of fair value and more accurately allocate the purchase price. The fair values of acquired intangibles are determined based on estimates and assumptions that are deemed reasonable by the Company. Significant assumptions include the discount rates and certain assumptions that form the basis of the forecasted results of the acquired business including revenue, earnings before interest, taxes, depreciation and amortization (“EBITDA”), and growth rates. These assumptions are forward looking and could be affected by future economic and market conditions. The Company engages third-party valuation specialists who review the Company’s critical assumptions and calculations of the fair value of acquired intangible assets in connection with material acquisitions. Only facts and circumstances that existed as of the acquisition date are considered for subsequent adjustment. The Company will make appropriate adjustments to the purchase price allocation prior to completion of the one-year measurement period, as required.

The purchase of these acquired businesses resulted in the recognition of goodwill in the Company’s consolidated financial statements, which is calculated as the excess of the consideration transferred over the net assets recognized and represents the future economic benefits arising from the other assets acquired that could not be individually identified and separately recognized. The goodwill is not amortized; goodwill is not deductible for income tax purposes for Biodex but is deductible for Dosimetry Badge. This goodwill recorded includes the following:

• The expected synergies and other benefits that we believe will result from combining the operations of the acquired business with the operations of Mirion;

• Any intangible assets that did not qualify for separate recognition, as well as future, yet unidentified projects and products;

• The value of the existing business as an assembled collection of net assets versus if the Company had acquired all of the net assets separately.

7. Goodwill and Intangible Assets

Goodwill

Goodwill is calculated as the excess of consideration transferred over the net assets recognized for acquired businesses and represents future economic benefits arising from the other assets acquired that could not be individually identified and separately recognized. The Company assesses goodwill for impairment at the reporting unit level annually during the fiscal fourth quarter and upon the occurrence of a triggering event or change in circumstance that would more likely than not reduce the fair value of a reporting unit below its carrying amount.

No goodwill impairment was recognized for the three-months ended September 30, 2021 and 2020.

The following table shows changes in the carrying amount of goodwill by reportable segment for the three-month period ended September 30, 2021 (in millions):

	Medical			Industrial			Consolidated
Balance—June 30, 2021	$	249.5		$	432.0		$	681.5

We do not expect most goodwill to be deductible for income tax purposes.

Intangible Assets

Intangible assets consist of our developed technology, customer relationships, backlog, trade names, and non-compete agreements at the time of acquisition through business combinations. The customer relationships definite lived intangible assets are amortized using the double declining balance method with estimated useful lives ranging from 6 to 17 years, while all other definite lived intangible assets are amortized on a straight-line basis over their estimated useful lives, ranging from 1 to 7 years.

Many of our intangible assets are not deductible for income tax purposes. A summary of intangible assets and related accumulated amortization (in millions) is below:

		September 30, 2021
	Original Average Life in Years	Gross Carrying Amount		Accumulated Amortization			Net Book Value

As of September 30, 2021 and June 30, 2021, the fair market value of the Company’s 2019 Credit Facility – first lien term loan was $900.6 million and $906.4 million, respectively. The fair market value for the credit facility were estimated using primarily level 2 inputs, including borrowing rates available to the Company at the respective period ends. The fair market value for the Company’s remaining third-party debt approximates the respective carrying amounts as of September 30, 2021 and June 30, 2021.

2019 Credit Facility

In March 2019, Mirion Technologies (HoldingRep), Ltd., a wholly owned subsidiary of the Company, and subsidiaries entered into a credit agreement with an intermediary and a syndicate of institutional lenders (“2019 Credit Facility”). The 2019 Credit Facility provided for financing of a $450.0 million senior secured term loan facility and a €125 million term loan facility, as well as a $90.0 million revolving line of credit. The 2019 Credit Facility was amended to provide an additional $225.0 million, $34.0 million and $66.0 million in gross proceeds from the USD term loan in December 2020, July 2019 and December 2019, respectively.

USD term loan – The term loan had a seven-year term (expiring March 2026), bearing interest at the greater of Adjusted London Interbank Offered Rate (“LIBOR”) or 0%, plus 4.00% and had quarterly principal repayments of 0.25% of the original principal balance. The interest rate was 4.08% and 4.15% at September 30, 2021 and June 30, 2021, respectively. The Company repaid $1.9 million and $1.4 million for the three-months ended September 30, 2021 and 2020, respectively.

Euro term loan—The Euro portion of the term loan had a seven-year term (expiring March 2026), bearing interest at the greater of European union interbank market (“Euribor”) or 0%, plus 4.25% and has quarterly principal repayments of 0.25% of the original principal balance. As of September 30, 2021 and June 30, 2021, the interest rate was 4.25%. The Company repaid $0.4 million during both the three-months ended September 30, 2021 and 2020.

Revolving Line of Credit—The revolving line of credit arrangement had a five-year term and bore interest at the greater of LIBOR or 0%, plus 4.00%. The agreement required the payment of a commitment fee of 0.50% per annum for unused commitments. The revolving line of credit had a maturity date in March 2024, at which time all outstanding revolving facility loans and accrued and unpaid interest were due. Any outstanding letters of credit reduce the availability of the revolving

15

line of credit. There was no outstanding balance under the arrangement as of September 31, 2021 and June 30, 2021. Additionally, the Company had standby letters of credit issued under its Credit Facility that reduced the availability under the revolver of $7.8 million and $8.7 million at September 30, 2021 and June 30, 2021, respectively; the amount available on the revolver was approximately $82.2 million and $81.3 million, respectively, for the same periods.

Deferred Financing Costs

In connection with the issuance of the 2019 Credit Facility, we incurred debt issuance costs of $16.3 million on date of issuance, with an additional $6.2 million and $1.2 million of costs for incremental proceeds in fiscal year 2021 and 2020, respectively. In accordance with accounting for debt issuance costs, we recognize, and present deferred finance costs associated with non-revolving debt and financing obligations as a reduction from the face amount of related indebtedness in our consolidated balance sheet.

In connection with the issuance of the 2019 Credit Facility revolving line of credit, we incurred debt issuance costs of $0.9 million. We recognize and present debt issuance costs associated with revolving debt arrangements as an asset and include the deferred finance costs within other assets on our consolidated balance sheet. We amortize all debt issuance costs over the life of the related indebtedness.

During the three-months ended September 30, 2021 and 2020, we incurred approximately $0.9 million and $0.6 million, respectively, of amortization expense of the deferred finance costs.

The 2019 Credit Facility was secured by a first priority lien on substantially all of Mirion HoldingRep and subsidiaries’ assets in the United States, certain assets of guarantor subsidiaries in Germany, United Kingdom, Canada, France, Belgium and Luxembourg, and two-thirds of assets in non-guarantors and other countries. Loan fees recorded as debt discounts are amortized using the effective interest method. The 2019 Credit Facility contained customary restrictive covenants, as well as financial covenants that required Mirion HoldingRep and subsidiaries to maintain in certain circumstances a total level of debt-to-income ratio and interest coverage ratio, each as defined in the 2019 Credit Facility, as well as non-financial affirmative and negative covenants. The negative covenants, subject to certain exceptions, generally limit the ability of Mirion HoldingRep and subsidiaries to incur additional debt, create liens, make fundamental changes, make certain investments, pay dividends, purchase or retire equity interests, or prepay or retire certain debt. Mirion HoldingRep and subsidiaries were in compliance with all debt covenants at both September 30, 2021 and June 30, 2021.

The 2019 Credit Facility was refinanced subsequent to September 30, 2021, in connection with the Closing; see Note 15 subsequent events disclosure.

Canadian Financial Institution—In May 2019, the Company entered into a credit agreement for C$1.7M ($1.3 million) with a Canadian financial institution that matures in April 2039. The note bears annual interest at 4.15%. The credit agreement is secured by the facility acquired using the funds obtained.

16

JLG Note Payable—In May 2019, the Company entered into a note payable for $0.2 million with an individual that has left the organization, which is due upon a change in control of Mirion Technologies (Global), Ltd, a wholly owned subsidiary of the Company. The note bears annual interest at 6.00%.

Performance Bonds and Other Credit Facilities

The Company has entered into various line of credit arrangements with local banks in France and Germany. These arrangements provide for the issuance of documentary and standby letters of credit of up to €67.3 million ($77.9 million) and €67.3 million ($79.9 million) as of September 30, 2021 and June 30, 2021, respectively, subject to certain local restrictions. As September 30, 2021 and June 30, 2021, €37.6 million ($43.6 million) and €24.7 million ($29.3 million), respectively, of the lines had been utilized to guarantee documentary and standby letters of credit, with interest rates ranging from 0.5% to 2.00%. In addition, the Company posts performance bonds with irrevocable letters of credit to support certain contractual obligations to customers for equipment delivery. These letters of credit are supported by restricted cash accounts, which totaled $1.0 million as of both September 30, 2021 and June 30, 2021.

At September 30, 2021 contractual principal payments of total third-party borrowings are as follows (in millions):

For the year ending June 30:
Remainder of 2022	$	6.9
2023		9.1
2024		9.0
2025		8.9
2026		867.4
Thereafter		2.7
Gross Payments		904.0
Unamortized debt issuance costs		(15.6	)
Total third-party borrowings, net of debt issuance costs	$	888.4

Notes payable to related parties consists of the following (in millions):

	September 30, 2021		June 30, 2021
Shareholder Notes	$	1,166.7	$	1,166.8
Management Notes		3.7		3.7
Notes payable to related parties	$	1,170.4	$	1,170.5

The estimated fair value of the Company’s related party debt was approximately $1,170.4 million and $1,170.5 million as of September 30, 2021 and June 30, 2021, respectively. The fair value of this instrument approximates book value due to the reasonable possibility of redemption prior to the term date.

Shareholder and Management Notes – Mirion Technologies (HoldingSub1), Ltd., is authorized to issue $900 million (plus accrued paid in-kind interest) of notes to shareholders (“Shareholder Notes”) and up to $5.0 million (plus paid in-kind cash and interest) of notes to certain members of management (“Management Notes”). The notes rank pari passu between each other and other unsecured obligations of the Company. The notes can be prepaid without penalty at the Company’s option and are subordinate in right of payment to any indebtedness of the Company to banks or to other financial institutions (either currently existing or to occur in the future). Certain of the Shareholder and Management Notes have been admitted to trading and are on the official listing of The International Stock Exchange (TISE).

17

For the fiscal year ended June 30, 2021, an additional $181.5 million in Shareholder Notes were admitted to trading and are on the official listing of TISE. No new Shareholder Notes were admitted to trading during the three months ended September 30, 2021. At September 30, 2021 and June 30, 2021, there were $1,158.4 million in Shareholder Notes issued and outstanding, respectively, as listed on TISE. Of the amount available for trading, $683.9 million relates to principal balance and $474.5 million relates to accrued interest as of September 30, 2021. There was no trading activity related to Shareholder and Management Notes during the three months ended September 30, 2021. As of September 30, 2021 and June 30, 2021 there were $3.6 million in Management Notes issued and outstanding, respectively, as listed on TISE.

The notes bear simple annual interest at 11.5% except for $70.0 million of Shareholder Notes added in fiscal year 2021 that bear a simple annual interest rate of 6.0% until October 1, 2021, when the interest rate will convert to a simple annual interest rate of 11.5%. For the Shareholder Notes, the interest is added to the principal outstanding on December 31 of each year until 2025 and is referred to as Shareholder Funding Bonds on TISE. For the Management Notes, half of the interest is added to the principal outstanding on December 31 of each year until 2025 and is referred to as Management Funding Bonds on TISE, while the remaining half is payable in cash annually. The listing on the Exchange for Shareholder and Management Funding Bonds is an optional election and certain shareholders have elected to opt-out of listing their Shareholder Funding Bonds. All other shareholders and management have elected to list their funding bonds on the Exchange. The notes are due when the Company completes a public offering, a winding-up, a sale, or on March 30, 2026, whichever occurs first. The redemption price is equal to the outstanding principal plus all accrued and unpaid interest then outstanding.

At September 30, 2021 and June 30, 2021, interest of $97.5 million and $64.6 million was accrued on the Shareholder Notes principal outstanding, respectively, and $0.2 million and $0.2 million was accrued on the Management Notes principal outstanding, respectively. As of December 31, 2020, accrued interest of $113.6 million was added to the principal of the Shareholder Notes and $0.2 million was added to the principal of the Management Notes.

Subsequent to September 30, 2021, the Shareholder Notes and Management Notes were extinguished at the Closing; see Note 15 for subsequent events disclosure.

9. Leased Properties

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

18

The table below presents the locations of the operating and financing lease assets and liabilities in the consolidated balance sheet as of September 30, 2021 (in millions):

	Balance Sheet Line Item	September 30, 2021
Operating lease assets	Operating lease assets	$	43.3
Financing lease assets	Other assets		1.1
Operating lease liabilities:
Current operating lease liabilities	Current operating lease liabilities	$	9.3
Noncurrent operating lease liabilities	Noncurrent operating lease liabilities		38.9
Total operating lease liabilities		$	48.2
Financing lease liabilities:
Current financing lease liabilities	Accrued expenses and other current liabilities	$	0.6
Noncurrent financing lease liabilities	Deferred income taxes and other long-term liabilities		0.5
Total financing lease liabilities		$	1.1

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

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

The Company’s weighted average remaining lease term and weighted average discount rate for operating leases as of September 30, 2021 are:

	September 30, 2021
Operating leases:
Weighted average remaining lease term (in years)		7.6
Weighted average discount rate		4.27	%

19

The table below reconciles the undiscounted future minimum lease payments (displayed by year and in the aggregate) under noncancelable operating lease with terms of more than one year to the total lease liabilities recognized on the consolidated balance sheets as of September 30, 2021 (in millions):

Fiscal year ending June 30:
2022	$	8.3
2023		9.4
2024		8.0
2025		6.8
2026		4.6
2027 and thereafter		19.5
Total undiscounted future minimum lease payments		56.6
Less: Imputed interest		(8.4	)
Total lease liabilities	$	48.2

For the 3-month period ending September 30, 2021, operating lease costs (as defined under ASU 2016-02) were $2.8 million. Operating lease costs are included within costs of goods sold, selling, general and administrative, and research and development expenses on the consolidated statements of income and comprehensive income. Short-term lease costs, variable lease costs and sublease income were not material for the periods presented.

Rental expense for operating leases (as defined prior to the adoption of ASU 2016-02) was approximately $2.0 million for the three months ending September 30, 2020.

Cash paid for amounts included in the measurement of operating lease liabilities was $2.9 million for the three months ended September 30, 2021, and this amount is included in operating activities in the consolidated statements of cash flows. Operating lease assets obtained in exchange for new operating lease liabilities were $0.2 million for the three months ended September 30, 2021.

10. Commitments and Contingencies

Unconditional Purchase Obligations

The Company has entered into certain long-term unconditional purchase obligations with suppliers. These agreements are non-cancellable and specify terms, including fixed or minimum quantities to be purchased, fixed or variable price provisions, and the approximate timing of payment. As of September 30, 2021, unconditional purchase obligations were $20.7 million and $8.1 million for the fiscal years ending June 30, 2022 and 2023.

Litigation

The Company is subject to various legal proceedings, claims, litigation, investigations and contingencies arising out of the ordinary course of business. While the ultimate results of such suits or other proceedings against us cannot be predicted with certainty, we believe the resolution of these matters will not have a material effect on our results of operations, financial condition, or cash flows. If we believe the likelihood of an adverse legal outcome is probable and the amount is reasonably estimable, we accrue a liability in accordance with accounting guidance for contingencies. We consult with legal counsel on matters related to litigation and seek input both within and outside the Company.

20

11. Income Taxes

The effective income tax rate for the three-months ended September 30, 2021 and September 30, 2020 was 9% and 2%, respectively. The difference in effective income tax rates and tax expense is primarily due to valuation allowances on losses incurred in the U.S. for the period ended September 30, 2020, as well as changes in the mix of earnings and jurisdictions. The Company’s effective income tax rates for the periods differ from the U.K. statutory rate of 19% primarily as a result of valuation allowances on certain UK losses.

12. Segment Information

The Company manages its operations through two operating and reportable segments: Medical and 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. Prior period information herein has been conformed to the current reportable segment structure.

Description of Segments

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 Industrial 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 following table summarizes select operating results for each reportable segment. The CODM evaluates operating results and allocates capital resources among segments, in part, based on segment income from operations, which includes revenues of the segment less expenses that are directly related to those revenues, including purchase accounting impacts to revenue and cost of revenues, but before certain charges to cost of revenues and selling, general and administrative expenses predominantly related to corporate costs, shared overhead and other non-operational costs related to restructuring activities and costs to achieve operational initiatives, which are included in Corporate and Other in the table below. Interest expense, loss on debt extinguishment, foreign currency loss (gain), net, and other expense (income), net are not allocated to segments.

13. Loss Per Share

A reconciliation of the numerator and denominator used in the calculation of basic and diluted loss per common share is as follows:

	For the three months ended September 30,
(In millions, except per share amounts)	2021			2020
Net loss attributable to Mirion Technologies (TopCo), Ltd. stockholders	$	(46.7	)	$	(40.4	)
Weighted average common shares outstanding – basic and diluted		6.665			6.478
Loss per share attributable to Mirion Technologies (TopCo), Ltd. stockholders – basic and diluted	$	(7.01	)	$	(6.24	)
Anti-dilutive employee share-based awards, excluded		0.2			0.3

Potentially dilutive unvested stock awards using the treasury stock method or the if-converted method, as applicable, are included when calculating diluted net income earnings (loss) per share attributable to Mirion Technologies (TopCo), Ltd. when their effect is dilutive. Because the Company incurred a net loss for the three-month periods ended September 30, 2021 and 2020, respectively, none of the potentially dilutive common shares were included in the diluted share calculations for those periods as they would have been anti-dilutive.

14. Restructuring

The Company incurs costs associated with restructuring initiatives intended to improve operating performance, profitability, and working capital levels. Actions associated with these initiatives may include improving productivity, workforce reductions, and the consolidation of facilities.

As of September 30, 2021, the Company has identified restructuring actions will result in additional charges of approximately $9.3 million, primarily in fiscal years 2022 and 2023.

23
