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 integration.

We operate and report our financial information in three reportable business segments: Healthcare, Applied Sterilization Technologies ("AST"), and Life Sciences. We describe our business segments in Note 10 titled "Business Segment Information."

Our fiscal year ends on March 31. References in this Quarterly Report to a particular "year," "fiscal," "fiscal 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.

A detailed description of our significant and critical accounting policies, estimates, and assumptions is included in our consolidated financial statements included in our Annual Report on Form 10-K for the year ended March 31, 2026, which was filed with the Securities and Exchange Commission ("SEC") on May 29, 2026. Our significant and critical accounting policies, estimates, and assumptions have not changed materially from March 31, 2026.

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, 2026, which was filed with the SEC on May 29, 2026. The Consolidated Balance Sheet at March 31, 2026 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 financial statements of the Company and its wholly-owned and majority-owned subsidiaries. We eliminate intercompany accounts and transactions when we consolidate these financial statements. 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.

Our reporting currency is United States Dollars (USD). Columns and rows within tables may not add due to rounding. Percentages have been calculated using actual, non-rounded figures.

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 month period ended June 30, 2026 are not necessarily indicative of results that may be expected for future quarters or for the full fiscal year ending March 31, 2027.

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 three months of fiscal 2027, $33.4 million of the March 31, 2026 deferred revenue balance was recorded as revenue. During the first three months of fiscal 2026, $38.5 million of the March 31, 2025 deferred revenue balance was recorded as revenue.

Refer to Note 7 titled, "Additional Consolidated Balance Sheet Information" for deferred revenue 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 June 30, 2026, the transaction price allocated to remaining performance obligations was approximately $1,541.4 million. We expect to recognize approximately 58% of the transaction price within one year and approximately 32% beyond one year. The remainder has yet to be scheduled for delivery.

Recently Issued Accounting Standards Impacting the Company

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 been adopted in fiscal 2027
ASU 2025-05 "Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses for Accounts Receivable and Contract Assets."	July 2025	The standard introduces a practical expedient allowing entities to assume current economic conditions, as of the balance sheet date, remain unchanged when estimating expected credit losses for current trade receivables and contract assets. The guidance is effective for fiscal years beginning after December 15, 2025, including interim periods.	First Quarter Fiscal 2027	We adopted this standard in fiscal 2027 with no material impact to the consolidated financial statements.
Standards that have not yet been adopted
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.	NA	We are currently assessing the impact of this standard update on our disclosures in the notes to the consolidated financial statements.

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

ASU 2025-06 "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) Targeted Improvements to the Accounting for Internal-Use Software	September 2025	The standard removes all references to prescriptive and sequential software development stages and requires entities to begin capitalizing software costs when management has both authorized and committed to funding the software project, and it is probable that the project will both be completed and the software will be used to perform the function intended. Capitalized internal-use software costs are now subject to the same disclosure requirements as property, plant, and equipment (PPE), even if they are presented as intangible assets or under a different line item. The amendments in this standard are effective for annual periods beginning after December 15, 2027 and interim reporting periods within those annual reporting periods, with early adoption permitted.	NA	We are in the process of evaluating the impact that the standard update will have on our consolidated financial statements.
ASU 2025-10 "Government Grants (Topic 832) Accounting for Government Grants Received by Business Entities"	December 2025	The standard provides authoritative guidance on the recognition, measurement, presentation, and disclosure of government grants received by business entities. The standard defines a government grant as a transfer of a monetary or tangible nonmonetary asset from a government to a business entity in a nonexchange transaction and requires a grant to be recognized only when it is probable that the entity will comply with the grant’s conditions and that the grant will be received. The amendments introduce an accounting model largely based on International Accounting Standard (IAS) 20, under which grants related to assets or income are recognized over the periods in which the related costs or expenses are incurred. The standard also amends Topic 832, which previously included only disclosure requirements, and provides guidance on presentation and repayment of grants. The guidance excludes certain transactions such as income tax items, below-market interest rate loans, and government guarantees from its scope. The amendments are effective for annual periods beginning after December 15, 2028 (including interim periods within those annual periods) for public business entities and one year later for all other entities. Early adoption is permitted.	NA	We are in the process of evaluating the impact that the standard update will have on our consolidated financial statements.
