Notes To Financial Statements [Abstract]
Significant Accounting Policies	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, life sciences and dental products and services. We offer our Customers a unique mix of innovative consumable products, such as detergents, endoscopy accessories, barrier products, and other products and services, including: equipment installation and maintenance, microbial reduction of medical devices, dental instruments and tools, instrument and scope repair, laboratory testing services, outsourced reprocessing, and capital equipment products, such as sterilizers and surgical tables, automated endoscope reprocessors, and connectivity solutions such as operating room (“OR”) integrati on. We operate and report in four reportable business segments: Healthcare, Applied Sterilization Technologies ("AST"), Life Sciences, and Dental. We describe our business segments in Note 9 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, 2023, which was filed with the Securities and Exchange Commission ("SEC") on May 26, 2023. The Consolidated Balance Sheet at March 31, 2023 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. 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, 2023 are not necessarily indicative of results that may be expected for future quarters or for the full fiscal year ending March 31, 2024. 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, 2023, assets related to costs to fulfill a contract were not material to our consolidated financial statements. Refer to Note 9 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 our 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 2024, $64,241 of the March 31, 2023 deferred revenue balance was recorded as revenue. During the first six months of fiscal 2023, $67,218 of the March 31, 2022 deferred revenue balance was recorded as revenue. Refer to Note 6 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 6 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 capital equipment and consumable orders which have not shipped. With regard to service, these remaining performance obligations primarily include installation, certification, and outsourced reprocessing services. As of September 30, 2023, the transaction price allocated to remaining performance obligations was approximately $1,579,938. We expect to recognize approximately 53% of the transaction price within one year and approximately 38% beyond one year. The remainder has yet to be scheduled for delivery.

Business Acquisitions and Divestitures [Abstract]
Business Combination Disclosure	2. Business Acquisitions On August 2, 2023, we purchased the surgical instrumentation, laparoscopic instrumentation and sterilization container assets from BD (Becton, Dickinson and Company) (NYSE: BDX). The acquired assets from BD are being integrated into our Healthcare segment. The purchase price of the acquisition was $539,758 and remains subject to post-closing adjustments to inventory. 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 existing credit facility. For more information, refer to Note 5 titled, " Debt." The table below summarizes the preliminary allocation of the purchase price to the net assets acquired from BD based on fair values at the acquisition date. BD (1) Inventory 27,006 Property, plant, and equipment 6,755 Intangible assets 303,598 Goodwill 202,399 Total assets acquired 539,758 Net assets acquired $ 539,758 (1) Purchase price allocation is still preliminary as of September 30, 2023, as valuation has not been finalized. During the first six months of fiscal 2023, we completed a tuck-in acquisition, which continued to expand our product and service offerings in the Healthcare segment. Total aggregate consideration was approximately $21,892, including contingent deferred consideration of $6,700. Acquisition and integration expenses totaled $16,013 and $18,722 for the three and six months ended September 30, 2023, respectively. Acquisition and integration expenses totaled $3,844 and $13,676 for the three and six months ended September 30, 2022, respectively. The increase in acquisition and integration expenses for the three and six months ended September 30, 2023 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. Acquisition and integration expenses are reported in the Selling, general and administrative expenses line of our Consolidated Statements of Income (Loss) and include but are not limited to investment banker, advisory, legal, other professional fees, and certain employee-related expenses.

Income Tax Disclosure [Abstract]
Income Tax Expense	7. Income Taxes The effective income tax rates for the three month periods ended September 30, 2023 and 2022 were 22.5% and 5.4%, respectively. The effective income tax rates for the six month periods ended September 30, 2023 and 2022 were 22.1% and (3.2)%, respectively. The fiscal 2024 effective tax rates increased when compared to fiscal 2023, primarily due to the tax impact of the goodwill impairment loss recognized on the Dental segment during the second quarter of fiscal 2023. Income tax expense (benefit) 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 2017. 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 impacts subsequent years through 2020. We estimate the total federal, state, and local tax impact of the settlement to be approximately $12,000, for the fiscal years 2016 through 2020, of which approximately $11,600 has been paid through September 30, 2023. In May 2021, we received two notices of proposed tax adjustment from the IRS regarding deemed dividend inclusions and associated withholding tax. 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. 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 it could be material to our consolidated results of operations and cash flows for any one period.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	8. 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. 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 below). 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, but there can be no assurance that these coverages 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 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 effect our business, performance, prospects, value, financial condition, and results of operations. For additional information regarding these matters, see the following portions of our Annual Report on Form 10-K for the year ended March 31, 2023, which was filed with the SEC on May 26, 2023, 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 7 to our consolidated financial statements titled, “Income Taxes” in this Quarterly Report on Form 10-Q.

Segment Reporting [Abstract]
Business Segment Information	9. Business Segment Information We operate and report our financial information in four reportable business segments: Healthcare, AST, Life Sciences and Dental. 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 products also include endoscopy accessories and capital equipment infrastructure used primarily in operating rooms, ambulatory surgery centers, endoscopy suites, and other procedural areas. Our AST segment is a third-party service provider for contract sterilization, as well as testing services needed to validate sterility services for medical device and pharmaceutical manufacturers. 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 that support pharmaceutical manufacturing, primarily for vaccine and other biopharma Customers focused on aseptic manufacturing. These solutions include a full suite of consumable products, equipment maintenance and specialty services, and capital equipment. Our Dental segment provides a comprehensive offering for dental practitioners and dental schools, offering instruments, infection prevention consumables and instrument management systems. 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 e nded September 30, 2023 and 2022 , revenues from a single Customer did not represent ten percent or more of the Healthcare, AST or Life Sciences segment revenues. Three Customers collectively and consistently account for approximately 40.0% of our Dental segment revenue. The percentage associated with these three Customers collectively in any one period may vary due to the buying patterns of these three Customers as well as other Dental Customers. These three Customers collectively accounted for appr oxi mately 43.8% and 43.1% o f our Dental segment revenues for the three and six months ended September 30, 2023, respectively. These three Customers collectively accounted for approximately 40.1% and 42.1% of our Dental segment revenues for the three and six months ended September 30, 2022, respectively. A dditional 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, 2023, which was filed with the SEC on May 26, 2023.

Earnings Per Share [Abstract]
Earnings Per Share	10. 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. 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): 2023 2022 2023 2022 Weighted average shares outstanding—basic 98,785 99,969 98,747 100,025 Dilutive effect of share equivalents (1) 621 — 576 — Weighted average shares outstanding and share equivalents—diluted 99,406 99,969 99,323 100,025 (1) The dilutive effect of share equivalents is excluded from the calculation of diluted earnings per share for the three and six months ended September 30, 2022 due to our net losses for those periods. 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) 2023 2022 2023 2022 Number of share options 625 642 647 467 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.

Repurchases of Ordinary Shares On May 3, 2023 our Board of Directors terminated the previous share repurchase program and authorized a new share repurchase program for the purchase of up to $500,000 (net of taxes, fees and commissions). As of September 30, 2023, we have not made any repurchases under this share repurchase program. This share repurchase program has no specified expiration date. Under the authorization, the Company may repurchase its shares from time to time through open market purchases, including 10b5-1 plans. Any share repurchases may be activated, suspended or discontinued at any time. During the first six months of fiscal 2024, we had no share repurchase activity pursuant to authorizations. During the first six months of fiscal 2023, we repurchased 292,487 of our ordinary shares for the aggregate amount of $59,561 (net of fees and commissions) pursuant to the authorizations. During the first six months of fiscal 2024, we obtained 57,161 of our ordinary shares in the aggregate amount of $9,213 in connection with share-based compensation award programs. During the first six months of fiscal 2023, we obtained 64,436 of our ordinary shares in the aggregate amount of $11,769 in connection with share-based compensation award programs.

Share-Based Payment Arrangement [Abstract]
Share-Based Compensation	12. Share-Based Compensation We maintain a long-term ince ntive plan that makes available shares for grants, at the discretion of the Board of Directors or the 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 options provide the right to purchase our shares at the market price on the date of grant, or for options granted to employees in fiscal 2019 and thereafter, 110% of the market price on the date of grant, subject to the terms of the plan and agreements. Generally, one-fourth of the stock options granted to employees become exercisable for each full year of employment following the grant date. Stock options granted generally expire 10 years after the grant date, or in some cases earlier if the option holder is no longer employed by us. Restricted shares and restricted share units generally cliff vest after a three or four year period or vest in equal tranches for each year of employment after the grant date. As of September 30, 2023, 2,367,257 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, which may be impacted by retirement eligibility, in our Consolidated Statements of Income (Loss). 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 2024 and 2023: Fiscal 2024 Fiscal 2023 Risk-free interest rate 3.59 % 2.44 % Expected life of options 6.0 years 5.9 years Expected dividend yield of stock 1.08 % 0.80 % Expected volatility of stock 27.92 % 24.49 % 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 2.22% and 2.54% was applied in fiscal 2024 and 2023, 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 Weighted Average Aggregate Outstanding at March 31, 2023 1,749,729 $ 154.60 Granted 253,946 220.24 Exercised (41,597) 60.07 Forfeited (2,128) 200.46 Outstanding at September 30, 2023 1,959,950 $ 165.06 6.3 years $ 114,142 Exercisable at September 30, 2023 1,338,836 $ 138.12 5.3 years $ 110,765 We estimate that 606,045 of the non-vested stock options outstanding at September 30, 2023 will ultimately vest. The aggregate intrinsic value in the table above represents the total pre-tax difference between the $219.42 closing price of our ordinary shares on September 30, 2023 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 2024 and fiscal 2023 was $6,467 and $4,553, respectively. Net cash proceeds from the exercise of stock options were $2,740 and $1,458 for the first six months of fiscal 2024 and fiscal 2023, respectively. The weighted average grant date fair value of stock option grants was $54.60 and $50.72 for the first six months of fiscal 2024 and fiscal 2023, respectively. A summary of the non-vested restricted share and share unit activity is presented below: Number of Number of Restricted Share Units Weighted Average Non-vested at March 31, 2023 450,793 28,542 $ 186.60 Granted 170,323 18,344 201.28 Vested (126,539) (12,787) 159.60 Forfeited (11,848) (1,171) 193.73 Non-vested at September 30, 2023 482,729 32,928 $ 199.06 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 2024 at the time of grant was $22,194. As of September 30, 2023, there was a total of $83,007 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 1.9 years. Cantel Share Based Compensation Plan In connection with the acquisition of Cantel, outstanding, non-vested Cantel restricted share units were replaced with STERIS restricted share units. As of September 30, 2023, there was a total of $103 in unrecognized compensation cost related to non-vested STERIS restricted shar e units awarded to replace Cantel restricted share units. We expect to recognize the majority of the remaining cost by the third quarter of fiscal 2024. A summary of the non-vested restricted share units activity associated with the Cantel share-based compensation plans is presented below: Number of Restricted Share Units Weighted Average Non-vested at March 31, 2023 15,670 $ 191.18 Vested (603) 191.18 Forfeited (762) 191.18 Non-vested at September 30, 2023 14,305 $ 191.18

Product Warranties Disclosures [Abstract]
Product Warranty Disclosure	13. 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 2024 were as follows: Warranties Balance at March 31, 2023 $ 13,683 Warranties issued during the period 8,205 Settlements made during the period (7,850) Balance at September 30, 2023 $ 14,038

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure	14. 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 2024, 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 2024. 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 (Loss). At September 30, 2023, we held net foreign currency forward contracts to buy 38.5 million British pounds sterling and 80.3 million Mexican pesos; and to sell 17.0 million Australian dollars, 11.0 million Canadian dollars, and 31.1 million euros. At September 30, 2023, we held commodity swap contracts to buy 376.5 thousand pounds of nickel.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	15. 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, 2023 and March 31, 2023: Fair Value Measurements Carrying Value Quoted Prices Significant Other Significant Level 1 Level 2 Level 3 September 30, March 31, September 30, March 31, September 30, March 31, September 30, March 31, Assets: Cash and cash equivalents $ 213,757 $ 208,357 $ 213,757 $ 208,357 $ — $ — $ — $ — Forward and swap contracts (1) 1,623 378 — — 1,623 378 — — Equity investments (2) 7,137 7,069 7,137 7,069 — — — — Other investments 2,793 2,066 2,793 2,066 — — — — Liabilities: Forward and swap contracts (1) $ 2,347 $ 2,054 $ — $ — $ 2,347 $ 2,054 $ — $ — Deferred compensation plans (2) 1,035 1,022 1,035 1,022 — — — — Debt (3) 3,437,179 3,078,655 — — 3,044,498 2,754,218 — — Contingent consideration obligations (4) 16,445 15,678 — — — — 16,445 15,678 (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)). We also hold an investment in the common stock of Servizi Italia, S.p.A, a leading provider of integrated linen washing and outsourced sterile processing services to hospital Customers. Changes in the fair value of these investments are recorded in the "Interest and miscellaneous (income) expense" line of the Consolidated Statement of Income (Loss). During the second quarter and first six months of fiscal 2024, we recorded gains of $65 and $138, respectively, related to these investments. During the second quarter and first six months of fiscal 2023, we recorded losses of $643 and $1,727,respectively, related to these investments. (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 arrangement s. (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. The changes in Level 3 assets and liabilities measured at fair value on a recurring basis at September 30, 2023 are summarized as follows: Contingent Consideration Balance at March 31, 2023 $ 15,678 Additions 860 Payments (39) Currency translation adjustments (54) Balance at September 30, 2023 $ 16,445

The Company's reporting units are equivalent to the reportable operating segments. As of the period ended September 30, 2023, there were no indicators that impairment of goodwill was more likely than not for any segment during the period. In the prior year period, we recorded a goodwill impairment charge of $490,565 related to our Dental segment. For more information regarding the goodwill impairment loss, refer to our Annual Report on Form 10-K for the year ended March 31, 2023, which was filed with the SEC on May 26, 2023.

Accounting Policies [Abstract]
Principles of Consolidation	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.
Use of Estimates	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, 2023 are not necessarily indicative of results that may be expected for future quarters or for the full fiscal year ending March 31, 2024.
Revenue	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, 2023, assets related to costs to fulfill a contract were not material to our consolidated financial statements. Refer to Note 9 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 our 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 2024, $64,241 of the March 31, 2023 deferred revenue balance was recorded as revenue. During the first six months of fiscal 2023, $67,218 of the March 31, 2022 deferred revenue balance was recorded as revenue. Refer to Note 6 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 6 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 capital equipment and consumable orders which have not shipped. With regard to service, these remaining performance obligations primarily include installation, certification, and outsourced reprocessing services.

(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)). We also hold an investment in the common stock of Servizi Italia, S.p.A, a leading provider of integrated linen washing and outsourced sterile processing services to hospital Customers. Changes in the fair value of these investments are recorded in the "Interest and miscellaneous (income) expense" line of the Consolidated Statement of Income (Loss). During the second quarter and first six months of fiscal 2024, we recorded gains of $65 and $138, respectively, related to these investments. During the second quarter and first six months of fiscal 2023, we recorded losses of $643 and $1,727,respectively, related to these investments. (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 arrangement s. (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.

[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)). We also hold an investment in the common stock of Servizi Italia, S.p.A, a leading provider of integrated linen washing and outsourced sterile processing services to hospital Customers. Changes in the fair value of these investments are recorded in the "Interest and miscellaneous (income) expense" line of the Consolidated Statement of Income (Loss). During the second quarter and first six months of fiscal 2024, we recorded gains of $65 and $138, respectively, related to these investments. During the second quarter and first six months of fiscal 2023, we recorded losses of $643 and $1,727,respectively, related to these investments.[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 arrangement s.
