On October 7, 2024, STERIS plc (“STERIS”), STERIS Corporation (the “Company”), STERIS Limited (“Limited”) and STERIS Irish FinCo Unlimited Company (“FinCo”), each as a borrower and guarantor, entered into a credit agreement with various financial institutions as lenders, and JPMorgan Chase Bank, N.A., as administrative agent (the “Revolving Credit Agreement”) providing for a $1,100,000 revolving credit facility (the “Revolving Credit Facility”), which replaced a prior credit agreement, dated as of March 19, 2021 (the “Previous Revolving Credit Facility”).

The Revolving Credit Agreement provides for revolving credit borrowings, swing line borrowings and letters of credit, with sublimits for swing line borrowings and letters of credit. The Revolving Credit Agreement may be increased in specified circumstances by up to $625,000 in the discretion of the lenders. The Revolving Credit Agreement matures on the date that is five years after October 7, 2024, and all unpaid borrowings, together with accrued and unpaid interest thereon, are repayable on that date. The Revolving Credit Facility bears interest from time to time, at either the Base Rate or the Relevant Rate, as defined in and calculated under and as in effect from time to time under the Revolving Credit Agreement, plus the Applicable Margin, as defined in the Revolving Credit Agreement. The Applicable Margin is determined based on the Debt Rating of STERIS, as defined in the Revolving Credit Agreement. Base Rate Advances are payable quarterly in arrears and Term Benchmark Advances are payable at the end of the relevant interest period therefor, but in no event less frequently than every three months.

Swingline borrowings bear interest at a rate to be agreed by the applicable swingline lender and the applicable borrower, subject to a cap in the case of swingline borrowings denominated in U.S. Dollars equal to the Base Rate plus the Applicable Margin for Base Rate Advances plus the Facility Fee. There is no premium or penalty for prepayment of Base Rate Advances, but prepayments of Term Benchmark Advances are generally subject to a breakage fee. Advances may be extended in U.S. Dollars or in specified alternative currencies (“Alternative Currency Advances”). Alternative Currency Advances are limited in the aggregate to the equivalent of $625,000.

Additional information regarding our indebtedness is included in the notes to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended March 31, 2024, which was filed with the SEC on May 29, 2024

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities Disclosure

16. Derivatives and Hedging

From time to time, we enter into forward contracts to hedge potential foreign currency gains and losses that arise from transactions denominated in foreign currencies, including intercompany transactions. We may also enter into commodity swap contracts to hedge price changes in nickel that impact raw materials included in our Cost of revenues. During the second quarter of fiscal 2025, we also held forward foreign currency contracts to hedge a portion of our expected non-U.S. dollar-denominated earnings against our reporting currency, the U.S. dollar. These foreign currency exchange contracts will mature in fiscal 2025. We did not elect hedge accounting for these forward foreign currency contracts; however, we may seek to apply hedge accounting in future scenarios. We do not use derivative financial instruments for speculative purposes.

These contracts are not designated as hedging instruments and do not receive hedge accounting treatment; therefore, changes in their fair value are not deferred but are recognized immediately in the Consolidated Statements of Income. At September 30, 2024, we held net foreign currency forward contracts to buy 58.0 million British pounds sterling; and to sell 18.0 million Australian dollars, 6.0 million Canadian dollars, and 1.8 million euros. At September 30, 2024, we held commodity swap contracts to buy 394.5 thousand pounds of nickel.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	10. Commitments and Contingencies We are, and will likely continue to be, involved in a number of legal proceedings, government investigations, and claims, which we believe generally arise in the course of our business, given our size, history, complexity, and the nature of our business, products, Customers, regulatory environment, and industries in which we participate. These legal proceedings, investigations and claims generally involve a variety of legal theories and allegations, including, without limitation, personal injury (e.g., slip and falls, burns, vehicle accidents), product liability or regulation (e.g., based on product operation or claimed malfunction, failure to warn, failure to meet specification, or failure to comply with regulatory requirements), product exposure (e.g., claimed exposure to chemicals, gases, asbestos, contaminants, radiation), property damage (e.g., claimed damage due to leaking equipment, fire, vehicles, chemicals), commercial claims (e.g., breach of contract, economic loss, warranty, misrepresentation), financial (e.g., taxes, reporting), employment (e.g., wrongful termination, discrimination, benefits matters), and other claims for damage and relief. A subsidiary of the Company has been sued in Illinois state court by individual plaintiffs who work or reside near a facility in Lake County, Illinois, where the subsidiary provided sterilization services using ethylene oxide (“EO”) from January 2005 to September 2008. The plaintiffs have filed separate suits in which each alleges that they have been diagnosed with one or more types of cancer, allegedly resulting from exposure to EO emissions from the facility into the ambient air. As of September 30, 2024, approximately 275 individual plaintiffs have filed such suits asserting individual personal injury claims and seeking compensatory and, if subsequently permitted by the court, punitive damages. The first trial of a plaintiff’s claims is scheduled for November 2024. The Company disputes the allegations, is vigorously defending itself in these matters, and is pursuing potential contribution and indemnity from other parties. Nonetheless, management believes that based on the number of cases and the overall cost of defense, a loss is reasonably possible; however, a range of loss cannot be reasonably estimated at this time because the evaluation of each case is highly fact-driven, subject to lengthy court proceedings, and impacted by each plaintiff's alleged disease, time and proximity of exposure, and other factors. We believe that the ultimate outcome of these pending lawsuits and claims will not have a material adverse effect on our consolidated financial position or results of operations taken as a whole. We believe we have adequately reserved for our current litigation and claims that are probable and estimable, and further believe that the ultimate outcome of these pending lawsuits and claims will not have a material adverse effect on our consolidated financial position or results of operations taken as a whole. Due to their inherent uncertainty, however, there can be no assurance of the ultimate outcome or effect of current or future litigation, investigations, claims or other proceedings (including without limitation the matters discussed above). For certain types of claims, we presently maintain insurance coverage for personal injury and property damage and other liability coverages in amounts and with deductibles that we believe are prudent, and we may also have contractual indemnification rights against certain liabilities, but there can be no assurance that either will be applicable or adequate to cover adverse outcomes of claims or legal proceedings against us. Civil, criminal, regulatory or other proceedings involving our products or services, including the matters discussed above, could possibly result in judgments, settlements or administrative or judicial decrees requiring us, among other actions, to pay damages or fines or effect recalls, or be subject to other governmental, Customer or other third party claims or remedies, which could materially affect our business, performance, prospects, value, financial condition, and results of operations. Further, the Company may incur material defense costs as a result of such proceedings, which may also divert management attention from other priorities. For additional information, see the following portions of our Annual Report on Form 10-K for the year ended March 31, 2024, which was filed with the SEC on May 29, 2024, Item 1 titled "Business - Information with respect to our Business in General - Government Regulation" and the "Risk Factors" in Item 1A titled "Product and service related regulations and claims." From time to time, STERIS is also involved in legal proceedings as a plaintiff involving contract, patent protection, and other claims asserted by us. Gains, if any, from these proceedings are recognized when they are realized. We are subject to taxation from United States federal, state and local, and foreign jurisdictions. Tax positions are settled primarily through the completion of audits within each individual jurisdiction or the closing of statutes of limitation. Changes in applicable tax law or other events may also require us to revise past estimates. We describe income taxes further in Note 9 to our consolidated financial statements titled, “Income Taxes” in this Quarterly Report on Form 10-Q.

- Definition

The entire disclosure for loss and gain contingencies. Describes any existing condition, situation, or set of circumstances involving uncertainty as of the balance sheet date (or prior to issuance of the financial statements) as to a probable or reasonably possible loss incurred by an entity that will ultimately be resolved when one or more future events occur or fail to occur, and typically discloses the amount of loss recorded or a range of possible loss, or an assertion that no reasonable estimate can be made.

Accounting Policies [Abstract]

New Accounting Pronouncement, Early Adoption

Recently Issued Accounting Standards Impacting the Company are presented in the following table:

Standard

Date of Issuance

Description

Date of Adoption

Effect on the financial statements or other significant matters

Standards that have not yet been adopted

ASU 2023-07 "Segment Reporting (Topic 280)
Improvements to Reportable Segment Disclosures."

November 2023

The standard provides guidance to enhance disclosures related to reportable segment expenses, including requirements to disclose significant segment expenses that are regularly provided to the Chief Operating Decision Maker ("CODM"), the title and position of the CODM and a description of how the CODM uses the information to make decisions regarding the allocation of resources. The standard also requires disclosure of certain segment information currently required annually to be reported on an interim basis. The amendments in this standard are effective for annual periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024.

We are currently assessing the impact of this standard update on our disclosures in the notes to the consolidated financial statements.

ASU 2023-09 "Income Taxes (Topic 740) Improvements to Income Tax Disclosures."

December 2023

The standard provides guidance to enhance disclosures related to income taxes paid (net of refunds), requiring disaggregation by federal, state, and foreign, and disclosure of income taxes paid (net of refunds received) by individual jurisdictions that represent greater than 5% of the total. The standard also requires disclosure of income (loss) from continuing operations before income taxes, disaggregated between domestic and foreign, and income tax expense (or benefit) disaggregated by federal, state, and foreign. Finally, the standard removes the requirement for certain disclosures related to changes in unrecognized tax benefits and certain amounts of temporary differences. The amendments in this standard are effective for annual periods beginning after December 15, 2024.

We are currently assessing the impact of this standard update on our disclosures in the notes to the consolidated financial statements.

ASU 2024-03

"Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40) Disaggregation of Income Statement Expenses."

November 2024

The standard provides guidance to enhance disclosures related to the disaggregation of income statement expenses. The standard requires, in the notes to the financial statements, disclosure of specified information about certain costs and expenses which includes purchases of inventory, employee compensation, depreciation, and intangible asset amortization included in each relevant expense caption. The standard also requires amounts that are already required to be disclosed under U.S. GAAP in the same disclosure as the other disaggregation requirements, disclosure of a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively, and disclosure of the total amount of selling expenses and, in annual reporting periods, an entity's definition of selling expenses. The amendments in this standard are effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027.

We are currently assessing the impact of this standard update on our disclosures in the notes to the consolidated financial statements.

Nature of Operations

1. Nature of Operations and Summary of Significant Accounting Policies

STERIS is a leading global provider of products and services that support patient care with an emphasis on infection prevention. WE HELP OUR CUSTOMERS CREATE A HEALTHIER AND SAFER WORLD by providing innovative healthcare and life science products and services around the globe. We offer our Customers a unique mix of innovative products and services. These include: consumable products, such as detergents, endoscopy accessories, barrier products, instruments and tools; services, including equipment installation and maintenance, microbial reduction of medical devices, instrument and scope repair, laboratory testing, and outsourced reprocessing; capital equipment, such as sterilizers, surgical tables, and automated endoscope reprocessors; and connectivity solutions such as operating room (“OR”) integration.

We operate and report our financial information in three reportable business segments: Healthcare, Applied Sterilization Technologies ("AST"), and Life Sciences. Previously, we had four reportable business segments, however, as a result of the divestiture of our Dental segment, Dental is presented as discontinued operations. Historical information has been retrospectively adjusted to reflect these changes for comparability purposes, as required. We describe our business segments in Note 11 titled "Business Segment Information."

Our fiscal year ends on March 31. References in this Quarterly Report to a particular “year” or “year-end” mean our fiscal year. The significant accounting policies applied in preparing the accompanying consolidated financial statements of the Company are summarized below:

Interim Financial Statements

We prepared the accompanying unaudited consolidated financial statements of the Company according to accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and the instructions to the Quarterly Report on Form 10-Q and Rule 10-01 of Regulation S-X. This means that they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. Our unaudited interim consolidated financial statements contain all material adjustments (including normal recurring accruals and adjustments) management believes are necessary to fairly state our financial condition, results of operations, and cash flows for the periods presented.

These interim consolidated financial statements should be read together with the consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended March 31, 2024, which was filed with the Securities and Exchange Commission ("SEC") on May 29, 2024. The Consolidated Balance Sheet at March 31, 2024 was derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements.

Principles of Consolidation

We use the consolidation method to report our investment in our subsidiaries. Therefore, the accompanying consolidated financial statements include the accounts of the Company and its wholly-owned and majority-owned subsidiaries. We eliminate intercompany accounts and transactions when we consolidate these accounts. Investments in equity of unconsolidated affiliates, over which the Company has significant influence, but not control, over the financial and operating polices, are accounted for primarily using the equity method. These investments are immaterial to the Company's consolidated financial statements.

Discontinued Operations

On April 11, 2024, the Company announced its plan to sell substantially all of the net assets of its Dental segment for total cash consideration of $787,500, subject to customary adjustments, and up to an additional $12,500 in contingent payment should the Dental business achieve certain revenue targets in fiscal 2025. The transaction was structured as an equity sale and closed on May 31, 2024. A component of an entity is reported in discontinued operations after meeting the criteria for held for sale classification if the disposition represents a strategic shift that has (or will have) a major effect on the entity's operations and financial results. We analyzed the quantitative and qualitative factors relevant to the divestiture of our Dental segment and determined that those conditions for discontinued operations presentation had been met prior to March 31, 2024. The Dental segment results of operations were reclassified to income (loss) from discontinued operations in the Consolidated Statements of Income for all periods presented, and we classified the Dental segment's assets and liabilities as held for sale for the year ended March 31, 2024 in the accompanying Consolidated Balance Sheets. Due to the transaction closing in the first quarter of fiscal 2025, the held for sale assets and liabilities were classified as current as of March 31, 2024. Our Consolidated Statements of Cash Flows include the financial results of the Dental segment through the date of sale on May 31, 2024. For additional information regarding this transaction and its effect on our financial reporting, refer to Note 4 titled, "Discontinued Operations" and Note 11 titled, "Business Segment Information."

Use of Estimates

We make certain estimates and assumptions when preparing financial statements according to U.S. GAAP that affect the reported amounts of assets and liabilities at the financial statement dates and the reported amounts of revenues and expenses during the periods presented. These estimates and assumptions involve judgments with respect to many factors that are difficult to predict and are beyond our control. Actual results could be materially different from these estimates. We revise the estimates and assumptions as new information becomes available. This means that operating results for the three and six month periods ended September 30, 2024 are not necessarily indicative of results that may be expected for future quarters or for the full fiscal year ending March 31, 2025.

Revenue Recognition and Associated Liabilities

Revenue is recognized when obligations under the terms of the contract are satisfied and control of the promised products or services have transferred to the Customer. Revenues are measured at the amount of consideration that we expect to be paid in exchange for the products or services. Product revenue is recognized when control passes to the Customer, which is generally based on contract or shipping terms. Service revenue is recognized when the Customer benefits from the service, which occurs either upon completion of the service or as it is provided to the Customer. Our Customers include end users as well as dealers and distributors who market and sell our products. Our revenue is not contingent upon resale by the dealer or distributor, and we have no further obligations related to bringing about resale. Our standard return and restocking fee policies are applied to sales of products. Shipping and handling costs charged to Customers are included in Product revenues. The associated expenses are treated as fulfillment costs and are included in Cost of revenues. Revenues are reported net of sales and value-added taxes collected from Customers.

We have individual Customer contracts that offer discounted pricing. Dealers and distributors may be offered sales incentives in the form of rebates. We reduce revenue for discounts and estimated returns, rebates, and other similar allowances in the same period the related revenues are recorded. The reduction in revenue for these items is estimated based on historical experience and trend analysis to the extent that it is probable that a significant reversal of revenue will not occur. Estimated returns are recorded gross on the Consolidated Balance Sheets.

In transactions that contain multiple performance obligations, such as when products, maintenance services, and other services are combined, we recognize revenue as each product is delivered or service is provided to the Customer. We allocate the total arrangement consideration to each performance obligation based on its relative standalone selling price, which is the price for the product or service when it is sold separately.

Payment terms vary by the type and location of the Customer and the products or services offered. Generally, the time between when revenue is recognized and when payment is due is not significant. We do not evaluate whether the selling price contains a financing component for contracts that have a duration of less than one year.

We do not capitalize sales commissions as substantially all of our sales commission programs have an amortization period of one year or less.

Certain costs to fulfill a contract are capitalized and amortized over the term of the contract if they are recoverable, directly related to a contract and generate resources that we will use to fulfill the contract in the future. At September 30, 2024, assets related to costs to fulfill a contract were not material to our consolidated financial statements.

Refer to Note 11 titled, "Business Segment Information" for disaggregation of revenue.

Product Revenues

Product revenues consist of revenues generated from sales of consumables and capital equipment. These contracts are primarily based on a Customer’s purchase order and may include a Distributor, Dealer or Group Purchasing Organization ("GPO") agreement. We recognize revenue for sales of products when control passes to the Customer, which generally occurs either when the products are shipped or when they are received by the Customer. Revenue related to capital equipment products is deferred until installation is complete if the capital equipment and installation are highly integrated and form a single performance obligation.

Service Revenues

Within our Healthcare and Life Sciences segments, service revenues include revenue generated from parts and labor associated with the maintenance, repair and installation of capital equipment. These contracts are primarily based on a Customer’s purchase order and may include a Distributor, Dealer, or GPO agreement. For maintenance, repair and installation of capital equipment, revenue is recognized upon completion of the service. Healthcare service revenues also include outsourced reprocessing services and instrument repairs. Contracts for outsourced reprocessing services are primarily based on an agreement with a Customer, ranging in length from several months to 15 years. Outsourced reprocessing services revenue is recognized ratably over the contract term using a time-based input measure, adjusted for volume and other performance metrics, to the extent that it is probable that a significant reversal of revenue will not occur. Contracts for instrument repairs are primarily based on a Customer’s purchase order, and the associated revenue is recognized upon completion of the repair.

We also offer preventive maintenance and separately priced extended warranty agreements to our Customers, which require us to maintain and repair products over the duration of the contract. Generally, these contract terms are cancellable without penalty and range from one to five years. Amounts received under these Customer contracts are initially recorded as a service liability and are recognized as service revenue ratably over the contract term using a time-based input measure.

Within our AST segment, service revenues include contract sterilization and laboratory services. Sales contracts for contract sterilization and laboratory services are primarily based on a Customer’s purchase order and associated Customer agreement, and revenues are generally recognized upon completion of the service.

Contract Liabilities

Payments received from Customers are based on invoices or billing schedules as established in contracts with Customers. Deferred revenue is recorded when payment is received in advance of performance under the contract. Deferred revenue is recognized as revenue upon completion of the performance obligation, which generally occurs within one year. During the first six months of fiscal 2025, $52,122 of the March 31, 2024 deferred revenue balance was recorded as revenue. During the first six months of fiscal 2024, $64,241 of the March 31, 2023 deferred revenue balance was recorded as revenue.

Refer to Note 8 titled, "Additional Consolidated Balance Sheet Information" for deferred revenue balances.

Service Liabilities

Payments received in advance of performance for cancellable preventive maintenance and separately priced extended warranty contracts are recorded as service liabilities. Service liabilities are recognized as revenue as performance is rendered under the contract.

Refer to Note 8 titled, "Additional Consolidated Balance Sheet Information" for service liability balances.

Remaining Performance Obligations

Remaining performance obligations reflect only the performance obligations related to agreements for which we have a firm commitment from a Customer to purchase, and exclude variable consideration related to unsatisfied performance obligations. With regard to products, these remaining performance obligations include orders for capital equipment and consumables where control of the products has not passed to the customer. With regard to service, these remaining performance obligations primarily include installation, certification, and outsourced reprocessing services. As of September 30, 2024, the transaction price allocated to remaining performance obligations was approximately $1,627,045. We expect to recognize

approximately 54% of the transaction price within one year and approximately 37% beyond one year. The remainder has yet to be scheduled for delivery.

Discontinued Operations

4. Discontinued Operations

On April 11, 2024, the Company announced its plan to sell substantially all of the net assets of its Dental segment for total cash consideration of $787,500, subject to customary adjustments, and up to an additional $12,500 in contingent payment should the Dental business achieve certain revenue targets in fiscal 2025. The transaction was structured as an equity sale and closed on May 31, 2024. A component of an entity is reported in discontinued operations after meeting the criteria for held for sale classification if the disposition represents a strategic shift that has (or will have) a major effect on the entity's operations and financial results. We analyzed the quantitative and qualitative factors relevant to the divestiture of our Dental segment and determined that those conditions for discontinued operations presentation had been met prior to March 31, 2024. The Dental segment results of operations were reclassified to income (loss) from discontinued operations in the Consolidated Statements of Income for all periods presented, and we classified the Dental segment's assets and liabilities as held for sale as of March 31, 2024 in the accompanying Consolidated Balance Sheets. Due to the transaction closing in the first quarter of fiscal 2025, the held for sale assets and liabilities were classified as current as of March 31, 2024. Our Consolidated Statements of Cash Flows include the financial results of the Dental segment through the date of sale on May 31, 2024. A majority of the proceeds received from the sale were utilized to pay off existing debt.

The following table summarizes the major classes of assets and liabilities of the Dental business segment that were classified as held for sale in the Consolidated Balance Sheets as of March 31, 2024:

Share-Based Payment Arrangement [Abstract]

Share-Based Compensation

14. Share-Based Compensation

We maintain a long-term incentive plan that makes available shares for grants, at the discretion of the Board of Directors or Compensation and Organizational Development Committee of the Board of Directors, to officers, directors, and key employees in the form of stock options, restricted shares, restricted share units, stock appreciation rights and share grants. We satisfy share award incentives through the issuance of new ordinary shares.

Stock option awards to employees generally vest and become nonforfeitable in increments of 25% per year over a four-year period, with full vesting four years after the date of grant. Historically, restricted stock awards to employee recipients generally cliff vested on the fourth anniversary of the grant date if the recipient remained in continuous employment through that date. Beginning with fiscal 2024 grants, Company restricted stock (and restricted stock units) generally cliff vest over a three year period after the grant date. However, employees who are grantees of restricted stock and have attained age 55 and been employed for at least five years at the time of the grant or meet these criteria during the term of the grant and are employed in the U.S. or in a few other foreign jurisdictions, or employees who have 25 years of service at the time of grant or meet that criterion during the term of the grant, will be subject to installment vesting rules over the applicable vesting period. Awards to certain employees in the U.S. or a few other jurisdictions may provide for continued vesting after “retirement,” if certain conditions are met. As of September 30, 2024, 2,020,289 ordinary shares remained available for grant under the long-term incentive plan.

The fair value of share-based stock option compensation awards was estimated at their grant date using the Black-Scholes-Merton option pricing model. This model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable, characteristics that are not present in our option grants. If the model permitted consideration of the unique characteristics of employee stock options, the resulting estimate of the fair value of the stock options could be different. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods in our Consolidated Statements of Income. The expense is classified as Cost of revenues or Selling, general, and administrative expenses in a manner consistent with the employee’s compensation and benefits.

The following weighted average assumptions were used for options granted during the first six months of fiscal 2025 and 2024:


	Fiscal 2025		Fiscal 2024
Risk-free interest rate	4.21	%	3.59	%
Expected life of options	6.1 years		6.0 years
Expected dividend yield of stock	0.94	%	1.08	%
Expected volatility of stock	28.42	%	27.92	%

The risk-free interest rate is based upon the U.S. Treasury yield curve. The expected life of options is reflective of historical experience, vesting schedules and contractual terms. The expected dividend yield of stock represents our best estimate of the expected future dividend yield. The expected volatility of stock is derived by referring to our historical stock prices over a time frame similar to that of the expected life of the grant. An estimated forfeiture rate of 2.07% and 2.22% was applied in fiscal 2025 and 2024, respectively. This rate is calculated based upon historical activity and represents an estimate of the granted options not expected to vest. If actual forfeitures differ from this calculated rate, we may be required to make additional adjustments to compensation expense in future periods. The assumptions used above are reviewed at the time of each significant option grant, or at least annually.

A summary of share option activity is as follows:


	Number of Options	Weighted Average Exercise Price Per Share		Average Remaining Contractual Term	Aggregate Intrinsic Value
Outstanding at March 31, 2024	1,869,871	$	168.22
Granted	217,426	250.76
Exercised	(188,205)	106.95
Forfeited	(7,008)	237.49
Expired	(512)	250.06
Outstanding at September 30, 2024	1,891,572	$	183.52	6.2 years	$	115,080
Exercisable at September 30, 2024	1,322,218	$	160.66	5.1 years	$	109,084

We estimate that 556,678 of the non-vested stock options outstanding at September 30, 2024 will ultimately vest.

The aggregate intrinsic value in the table above represents the total pre-tax difference between the $242.54 closing price of our ordinary shares on September 30, 2024 over the exercise prices of the stock options, multiplied by the number of options outstanding or outstanding and exercisable, as applicable. The aggregate intrinsic value is not recorded for financial accounting purposes and the value changes daily based on the daily changes in the fair market value of our ordinary shares.

The total intrinsic value of stock options exercised during the first six months of fiscal 2025 and fiscal 2024 was $24,446 and $6,467, respectively. Net cash proceeds from the exercise of stock options were $19,092 and $2,740 for the first six months of fiscal 2025 and fiscal 2024, respectively.

The weighted average grant date fair value of stock option grants was $67.81 and $54.60 for the first six months of fiscal 2025 and fiscal 2024, respectively.

A summary of the non-vested restricted share and share unit activity is presented below:


	Number of Restricted Shares	Number of Restricted Share Units	Weighted Average Grant Date Fair Value
Non-vested at March 31, 2024	463,381	28,348	$	200.04
Granted	156,202	16,367	228.77
Vested	(127,532)	(11,424)	185.66
Forfeited	(30,490)	(1,573)	206.80
Non-vested at September 30, 2024	461,561	31,718	$	213.79

Restricted shares and restricted share unit grants are valued based on the closing stock price at the grant date. The value of restricted shares and units that vested during the first six months of fiscal 2025 at the time of grant was $25,968.

As of September 30, 2024, there was a total of $75,899 in unrecognized compensation cost related to non-vested share-based compensation granted under our share-based compensation plans. We expect to recognize the cost over a weighted average period of 1.7 years.

Earnings Per Share [Abstract]

Earnings Per Share

12. Shares and Preferred Shares

Ordinary shares

We calculate basic earnings per share based upon the weighted average number of shares outstanding. We calculate diluted earnings per share based upon the weighted average number of shares outstanding plus the dilutive effect of share equivalents calculated using the treasury stock method. Income from continuing operations is used as the benchmark to determine whether share equivalents are dilutive or anti-dilutive. Earnings per share is calculated independently for earnings per share from continuing operations and earnings per share from discontinued operations. The sum of earnings per share from continuing operations and earnings per share from discontinued operations may not equal total company earnings per share due to rounding.

The following is a summary of shares and share equivalents outstanding used in the calculations of basic and diluted earnings per share:


	Three Months Ended September 30,		Six Months Ended September 30,
Denominator (shares in thousands):	2024	2023	2024	2023
Weighted average shares outstanding—basic	98,669	98,785	98,769	98,747
Dilutive effect of share equivalents	535	621	521	576
Weighted average shares outstanding and share equivalents—diluted	99,204	99,406	99,290	99,323

Options to purchase the following number of shares were outstanding but excluded from the computation of diluted earnings per share because the combined exercise prices, unamortized fair values, and assumed tax benefits upon exercise were greater than the average market price for the shares during the periods, so including these options would be anti-dilutive:


	Three Months Ended September 30,		Six Months Ended September 30,
(shares in thousands)	2024	2023	2024	2023
Number of share options	599	625	632	647

Additional Authorized Shares

The Company has an additional authorized share capital of 50,000,000 preferred shares of $0.001 par value each, plus 25,000 deferred ordinary shares of €1.00 par value each, in order to satisfy minimum statutory capital requirements for all Irish public limited companies.

Product Warranties Disclosures [Abstract]

Product Warranty Disclosure

15. Financial and Other Guarantees

We generally offer a limited parts and labor warranty on capital equipment. The specific terms and conditions of those warranties vary depending on the product sold and the countries where we conduct business. We record a liability for the estimated cost of product warranties at the time product revenues are recognized. The amounts we expect to incur on behalf of our Customers for the future estimated cost of these warranties are recorded as a current liability on the accompanying Consolidated Balance Sheets. Factors that affect the amount of our warranty liability include the number and type of installed units, historical and anticipated rates of product failures, and material and service costs per claim. We periodically assess the adequacy of our recorded warranty liabilities and adjust the amounts as necessary.

Changes in our warranty liability during the first six months of fiscal 2025 were as follows:

(1) The fair values of forward and swap contracts are based on period-end forward rates and reflect the value of the amount that we would pay or receive for the contracts involving the same notional amounts and maturity dates.

(2) We maintain a frozen domestic non-qualified deferred compensation plan covering certain employees, which allowed for the deferral of payment of previously earned compensation for an employee-specified term or until retirement or termination. Amounts deferred can be allocated to various hypothetical investment options (compensation deferrals have been frozen under the plan). We hold investments to satisfy the future obligations of the plan. Employees who made deferrals are entitled to receive distributions of their hypothetical account balances (amounts deferred, together with earnings (losses)). Changes in the fair value of these investments are recorded in the "Interest and miscellaneous income" line of the Consolidated Statement of Income. During the first three and six months of fiscal 2025, we recorded gains of $51 and $104, respectively, related to these investments. During the first three and six months of fiscal 2024, we recorded gains of $65 and $138, respectively, related to these investments. We also held other equity investments in which we recorded a loss during the second quarter of fiscal 2025 in the "Loss (gain) on sale of business and equity investment, net" line of the Consolidated Statement of Income.

(3) We estimate the fair value of our debt using discounted cash flow analyses, based on estimated current incremental borrowing rates for similar types of borrowing arrangements. The fair values of our Senior Public Notes are estimated using quoted market prices for the Senior Public Notes.

(4) Contingent consideration obligations arise from prior business acquisitions. The fair values are based on discounted cash flow analyses reflecting the possible achievement of specified performance measures or events and captures the contractual nature of the contingencies, commercial risk, and the time value of money. Contingent consideration obligations are classified in the consolidated balance sheets as accrued expense (short-term) and other liabilities (long-term), as appropriate based on the contractual payment dates.

Fair Value Disclosures [Abstract]

Fair Value Disclosures

17. Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. We estimate the fair value of financial assets and liabilities using available market information and generally accepted valuation methodologies. The inputs used to measure fair value are classified into three tiers. These tiers include Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring the entity to develop its own assumptions.

The following table shows the fair value of our financial assets and liabilities at September 30, 2024 and March 31, 2024:


					Fair Value Measurements
	Carrying Value				Quoted Prices in Active Markets for Identical Assets				Significant Other Observable Inputs				Significant Unobservable Inputs
					Level 1				Level 2				Level 3
	September 30,		March 31,		September 30,		March 31,		September 30,		March 31,		September 30,		March 31,
Assets:

The changes in Level 3 assets and liabilities measured at fair value on a recurring basis at September 30, 2024 are summarized as follows:

Segment Reporting [Abstract]

Business Segment Information

11. Business Segment Information

We operate and report our financial information in three reportable business segments: Healthcare, AST, and Life Sciences. Previously, we had four reportable business segments, however, as a result of the divestiture of our Dental segment, Dental is presented as discontinued operations. Historical information has been retrospectively adjusted to reflect these changes for comparability, as required. For more information, refer to Note 4 titled, "Discontinued Operations." Non-allocated operating costs that support the entire Company and items not indicative of operating trends are excluded from segment operating income.

Our Healthcare segment provides a comprehensive offering for healthcare providers worldwide, focused on sterile processing departments and procedural centers, such as operating rooms and endoscopy suites. Our products and services range from infection prevention consumables and capital equipment, as well as services to maintain that equipment; to the repair of re-usable procedural instruments; to outsourced instrument reprocessing services. In addition, our procedural solutions also include endoscopy accessories, instruments, and capital equipment infrastructure used primarily in operating rooms, ambulatory surgery centers, endoscopy suites, and other procedural areas.

Our AST segment supports medical device and pharmaceutical manufacturers through a global network of contract sterilization and laboratory testing facilities, and integrated sterilization equipment and control systems. Our technology-neutral offering supports Customers every step of the way, from testing through sterilization.

Our Life Sciences segment provides a comprehensive offering of products and services designed to support biopharmaceutical and medical device research and manufacturing facilities, in particular those focused on aseptic manufacturing. Our portfolio includes a full suite of capital equipment, consumable products, equipment maintenance and specialty services.

We disclose a measure of segment income that is consistent with the way management operates and views the business. The accounting policies for reportable segments are the same as those for the consolidated Company.

For the three and six months ended September 30, 2024 and 2023, revenues from a single Customer did not represent ten percent or more of the Healthcare, AST or Life Sciences segment revenues.

Additional information regarding our segments is included in our consolidated financial statements included in our Annual Report on Form 10-K for the year ended March 31, 2024, which was filed with the SEC on May 29, 2024.

Financial information for each of our segments is presented in the following table:

Restructuring

Restructuring and Related Activities [Abstract]

Restructuring

2. Restructuring

In May 2024, we adopted and announced a targeted restructuring plan (the "Restructuring Plan"). This plan includes a strategic shift in our approach to the Healthcare surgical business in Europe, as well as other actions including the impairment of an internally developed X-ray accelerator, product rationalizations and facility consolidations. Fewer than 300 positions are being eliminated. These restructuring actions are designed to enhance profitability and improve efficiency, and we expect these actions to be substantially complete by the end of fiscal 2025.

The following tables summarize our total pre-tax restructuring expenses recorded in fiscal 2025 related to the Restructuring Plan:


	Three Months Ended September 30,		Six Months Ended September 30,
Restructuring Plan
Severance and other compensation related costs	$	1,805	$	23,285
Lease and other contract termination and other costs	991		3,961
Product rationalization (1)	—		2,382
Accelerated depreciation and amortization	—		1,250
Total Restructuring Expense	$	2,796	$	30,878

(1) Recorded in Cost of revenues on the Consolidated Statements of Income.

The Restructuring Plan expenses incurred during the three and six months ended September 30, 2024 primarily related to actions taken within our Healthcare segment. Total pre-tax restructuring expense of $75,268 has been recorded relating to the Restructuring Plan since inception, of which $20,702 has been recorded in Cost of revenues.

Income Tax Disclosure [Abstract]
Income Tax Expense	9. Income Taxes Our effective tax rate is affected by (i) the tax rates in Ireland (our country of domicile), the United States, and other jurisdictions in which we operate, and (ii) the relative amount of income before income taxes by geography. The effective income tax rates for the three month periods ended September 30, 2024 and 2023 from continuing operations were 22.3% and 22.5%, respectively. The effective income tax rates for the six month periods ended September 30, 2024 and 2023 from continuing operations were 21.3% and 22.1%, respectively. The fiscal 2025 effective tax rates decreased when compared to fiscal 2024, primarily due to changes in geographic mix of projected profits and an increase in favorable discrete items. Income tax expense is provided on an interim basis based upon our estimate of the annual effective income tax rate, adjusted each quarter for discrete items. In determining the estimated annual effective income tax rate, we analyze various factors, including projections of our annual earnings and taxing jurisdictions in which the earnings will be generated, the impact of state and local income taxes, our ability to use tax credits and net operating loss carry forwards, and available tax planning alternatives. We operate in numerous taxing jurisdictions and are subject to regular examinations by various United States federal, state and local, as well as foreign jurisdictions. We are no longer subject to United States federal examinations for years before fiscal 2018 and, with limited exceptions, we are no longer subject to United States state and local, or non-United States, income tax examinations by tax authorities for years before fiscal 2018. We remain subject to tax authority audits in various jurisdictions wherever we do business. In the fourth quarter of fiscal 2021, we completed an appeals process with the U.S. Internal Revenue Service (the “IRS”) regarding proposed audit adjustments related to deductibility of interest paid on intercompany debt for fiscal years 2016 through 2017. An agreement was reached on final interest rates, which also impacted subsequent years through 2020. The total federal, state, and local tax impact of the settlement including interest is approximately $12,000 for the fiscal years 2016 through 2020, materially all of which has been paid through September 30, 2024. In November 2023, we received two Notices of Deficiency from the IRS regarding the previously disclosed deemed dividend inclusions and associated withholding tax matter. The notices relate to the fiscal and calendar year 2018. The IRS adjustments would result in a cumulative tax liability of approximately $50,000. We are contesting the IRS’s assertions and have filed petitions with the U.S. Tax Court. We have not established reserves related to these notices. An unfavorable outcome is not expected to have a material adverse impact on our consolidated financial position but could be material to our consolidated results of operations and cash flows for any one period.

Business Acquisitions and Divestitures [Abstract]

Business Combination Disclosure

3. Business Acquisitions and Divestitures

Acquisitions

During the first six months of fiscal 2025, we completed several tuck-in acquisitions, which continued to expand our product and service offerings in the Healthcare and AST segments. Total aggregate consideration was approximately $17,467.

On August 2, 2023, we purchased the surgical instrumentation, laparoscopic instrumentation and sterilization container assets from Becton, Dickinson and Company (NYSE: BDX) ("BD"). The acquired assets from BD were integrated into our Healthcare segment.

The purchase price of the BD acquisition was $539,758. The acquisition also qualified for a tax benefit related to tax deductible goodwill, with a present value of approximately $60,000. The purchase price of the acquisition was financed with borrowings from our Previous Revolving Credit Facility. For more information, refer to Note 7 titled, "Debt."

The table below summarizes the allocation of the purchase price to the net assets acquired from BD based on fair values at the acquisition date.



	September 30, 2023 (As Previously Reported)		Adjustments (2)		Final


Inventory	27,006		4,821		31,827
Property, plant, and equipment	6,755		1,109		7,864
Lease right-of-use assets, net	—		1,737		1,737

Intangible assets (1)	303,598		(598)		303,000
Goodwill	202,399		(5,332)		197,067
Total assets acquired	539,758		1,737		541,495

Lease obligations	—		1,737		1,737
Total liabilities assumed	—		1,737		1,737
Net assets acquired	$	539,758	$	—	$	539,758

(2) No additional adjustments made during fiscal 2025.

Acquisition and integration expenses totaled $3,205 and $5,459 for the three and six months ended September 30, 2024, respectively. Acquisition and integration expenses totaled $15,808 and $18,045 for the three and six months ended September 30, 2023, respectively. The decrease in acquisition and integration expenses for the three and six months ended September 30, 2024 is primarily due to charges related to the acquisition of assets from BD and a fair value adjustment related to a building held for sale from a previous acquisition during fiscal 2024. Acquisition and integration expenses are reported in the Selling, general and administrative expenses line of our Consolidated Statements of Income and include, but are not limited to, investment banker, advisory, legal and other professional fees, and certain employee-related expenses.

Divestitures

On April 11, 2024, the Company announced its plan to sell its Dental segment for total cash consideration of $787,500, subject to customary adjustments, and up to an additional $12,500 in contingent payment should the Dental business achieve certain revenue targets in fiscal 2025. The transaction was structured as an equity sale and closed on May 31, 2024. The disposal of the Dental segment met the criteria to be presented as a discontinued operation. For more information refer to Note 4 titled "Discontinued Operations."

On April 1, 2024, we completed the sale of the Controlled Environment Certification Services business. We recorded net proceeds of $41,894 and recognized a pre-tax gain on the sale of $19,151 in fiscal 2025. The business generated approximately $35,000 in revenues in fiscal 2024.
