DUBLIN, IRELAND - (February 4, 2026) - STERIS plc (NYSE: STE) (“STERIS” or the “Company”) today announced financial results for its fiscal 2026 third quarter ended December 31, 2025. T1Total revenue from continuing operations for the third quarter of fiscal 2026 increased 9% to $1.5 billion compared with $1.4 billion in the third quarter of fiscal 2025. Constant currency organic revenue growth from continuing operations for the third quarter was 8%.

“We are pleased with our performance in the third quarter,” said Dan Carestio, President and CEO of STERIS. “Our performance continues to benefit from strong execution by our commercial teams and our diversified portfolio. T2High single digit revenue growth combined with cost discipline is allowing us to deliver meaningful earnings per share growth despite increased tariff headwinds.”

Total Company Third Quarter Results from Continuing Operations

As reported, net income from continuing operations for the third quarter was $192.9 million or $1.96 per diluted share, compared with $173.6 million or $1.75 per diluted share in the third quarter of fiscal 2025. Adjusted net income for the third quarter of fiscal 2026 was $249.4 million or $2.53 per diluted share, compared with the previous year’s third quarter of $229.1 million or $2.32 per diluted share.

Third Quarter Segment Results from Continuing Operations

T3Healthcare revenue as reported grew 9% in the third quarter to $1.1 billion compared with $976.0 million in the third quarter of fiscal 2025. This performance reflected 11% improvement in service revenue, 8% growth in consumable revenue and 7% growth in capital equipment revenue. Constant currency organic revenue growth was 8% compared to last year’s third quarter. Healthcare operating income was $258.1 million compared with $246.9 million in last year’s third quarter. The increase in operating income was primarily due to improved volume, price, productivity and the benefit of prior restructuring efforts, which were partially offset by tariff costs and inflation.

Fiscal 2026 third quarter revenue for Applied Sterilization Technologies (AST) increased 11% as reported to $286.6 million compared with $258.1 million in the same period last year. This performance reflected 9% growth in service revenue and a 103% growth in capital equipment revenue. Constant currency organic revenue growth was 8% compared to last year’s third quarter. Segment operating income was $129.2 million in the third quarter of fiscal 2026, compared with operating income of $115.8 million in the same period last year. The operating income increase compared with the prior year primarily reflects improved price and volume, which were partially offset by continued headwinds in labor and energy costs and unfavorable mix.

Life Sciences third quarter revenue as reported increased 7% to $145.8 million compared with $136.4 million in the third quarter of fiscal 2025. This performance reflected 11% growth in consumable revenue, 7% growth in capital equipment revenue and flat service revenue. Constant currency organic revenue increased 5% compared to last year’s third quarter. Operating income increased to $61.8 million in the third quarter of fiscal 2026 compared with $58.1 million in the prior year’s third quarter. The operating income increase compared with the prior year primarily reflects improved volume and price, which were partially offset by inflation and tariff costs.

Cash Flow

Net cash provided by operations for the first nine months of fiscal 2026 was $1.0 billion, compared with $887.3 million in the first nine months of fiscal 2025. T4Free cash flow for the first nine months of fiscal 2026 was $737.6 million compared with $588.1 million in the prior year period. The increase in free cash flow during the period was driven primarily by the growth in earnings and lower capital spending.

Fiscal 2026 Outlook Maintained

G1T5For fiscal 2026, the Company expects as reported revenue from continuing operations to increase 8-9%, G2and constant currency organic revenue from continuing operations growth of 7-8%. G3Adjusted earnings per diluted share from continuing operations are expected to be in the range of $10.15 to $10.30. T6Included in this outlook is the negative impact of tariffs, estimated to reduce pre-tax profit by approximately $55 million, an increase from prior expectations of approximately $45 million. The fiscal 2026 outlook assumes an effective tax rate of approximately 24%.

G4Capital expenditures are anticipated to be approximately $375 million, G5and free cash flow is expected to be approximately $850 million.

Non-GAAP Financial Measures

Adjusted net income, adjusted income from operations, free cash flow, adjusted EPS and constant currency organic revenue are non-GAAP measures that may be used from time to time and should not be considered replacements for U.S. GAAP results. Non-GAAP financial measures are presented in this release with the intent of providing greater transparency to supplemental financial information used by management and the Board of Directors in their financial analysis and operational decision making. These amounts are disclosed so that the reader has the same financial data that management uses with the belief that it will assist investors and other readers in making comparisons to our historical operating results and analyzing the underlying performance of our operations for the periods presented.

The Company believes that the presentation of these non-GAAP financial measures, when considered along with our U.S. GAAP financial measures, provides a more complete understanding of the factors and trends affecting our business than could be obtained absent this disclosure.

Adjusted net income, adjusted EPS and adjusted income from operations exclude the amortization of intangible assets acquired in business combinations, acquisition and divestiture related transaction costs and gains or losses, integration costs related to acquisitions, tax restructuring costs, and certain other unusual or non-recurring items. STERIS believes this measure is useful because it excludes items that may not be indicative of or are unrelated to our core operating results and provides a baseline for analyzing trends in our underlying businesses.

The Company defines free cash flow as cash flows from operating activities less purchases of property, plant, equipment and intangibles, plus proceeds from the sale of property, plant, equipment, and intangibles. STERIS believes that free cash flow is a useful measure of the Company’s ability to fund future principal debt repayments and growth outside of core operations, pay cash dividends, and repurchase ordinary shares. To measure the percentage organic revenue growth, the Company removes the impact of significant acquisitions and divestitures that affect the comparability and trends in revenue.

To measure the percentage constant currency organic revenue growth, the impact of changes in currency exchange rates and acquisitions and divestitures that affect the comparability and trends in revenue are removed. The impact

of changes in currency exchange rates is calculated by translating current year results at prior year average currency exchange rates.

Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies’ non-GAAP financial measures having the same or similar names. These adjusted financial measures should not be considered in isolation or as a substitute for reported sales, gross profit, operating income, net earnings and net earnings per diluted share, the most directly comparable U.S. GAAP financial measures. These non-GAAP financial measures are an additional way of viewing aspects of the Company’s operations that, when viewed with U.S. GAAP results and the reconciliations to corresponding U.S. GAAP financial measures below, provide a more complete understanding of the business. The Company strongly encourages investors and shareholders to review its financial statements and publicly-filed reports in their entirety and not to rely on any single financial measure.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION This release may contain statements concerning certain trends, expectations, forecasts, estimates, or other forward-looking information affecting or relating to STERIS or its industry, products or activities that are intended to qualify for the protections afforded “forward-looking statements” under the Private Securities Litigation Reform Act of 1995 and other laws and regulations. Forward-looking statements speak only as to the date the statement is made and may be identified by the use of forward-looking terms such as “may,” “will,” “expects,” “believes,” “anticipates,” “plans,” “estimates,” “projects,” “targets,” “forecasts,” “outlook,” “impact,” “potential,” “confidence,” “improve,” “optimistic,” “deliver,” “orders,” “backlog,” “comfortable,” “trend,” and “seeks,” or the negative of such terms or other variations on such terms or comparable terminology.

Many factors could cause actual results to differ materially from those in the forward-looking statements including, without limitation, those identified in STERIS’s recent Annual Report on Form 10-K and other filings with the Securities and Exchange Commission. Other potential risks and uncertainties that could cause actual results to differ materially from those in the forward-looking statements include, without limitation: (a) T7operating costs, pressure on pricing (including, without limitation, as a result of inflation), Customer loss and business disruption (including, without limitation, difficulties in maintaining relationships with employees, Customers, clients or suppliers) being greater than expected and leading to erosion of profit margins; (b) STERIS’s ability to successfully integrate acquired businesses into its existing businesses, including unknown or inestimable liabilities, impairments, or increases in expected integration costs or difficulties in connection with the integration of such businesses; (c) changes in tax laws or interpretations or the adoption of certain income tax treaties in jurisdictions where we operate that could increase our consolidated tax liabilities, including changes in tax laws that would result in STERIS being treated as a domestic corporation for United States federal tax purposes, or tariffs and/or other trade barriers; (d) the possibility that compliance with laws, court rulings, certifications, regulations, or other regulatory actions, or the outcome of any pending or threatened litigation, including the ethylene oxide litigation, may delay, limit or prevent new product or service introductions, impact production, supply and/or marketing of existing products or services, result in uncovered costs, or otherwise affect STERIS’s performance, results, prospects or value; (e) the potential of international unrest, including military conflicts, economic downturn and effects of currency fluctuations; (f) the possibility of delays in receipt of orders, order cancellations, or the manufacture or shipment of ordered products; (g) the possibility that anticipated growth, performance or other results may not be achieved, or that timing, execution, impairments, or other issues associated with STERIS’s businesses, industry or initiatives may adversely impact STERIS’s performance, results, prospects or value; (h) the impact on STERIS and its operations of any legislation, regulations or orders, including but not limited to any new trade, regulations or orders, that may be implemented by the U.S. administration or Congress, or of any responses thereto by non-U.S. governments; (i) the possibility that anticipated financial results, anticipated revenue, productivity improvements, cost savings, growth synergies, and other anticipated benefits of acquisitions, restructuring efforts, and divestitures will not be realized or will be less than anticipated; (j) the level of STERIS’s indebtedness limiting financial flexibility or increasing future borrowing costs; (k) the effects of changes in credit availability and pricing, as well as the ability of STERIS and STERIS’s Customers and suppliers to adequately access the credit markets, on favorable terms or at all, when needed; (l) the impacts of increasing competition within our industry, which may exert pressure on our pricing strategy or lead to decreasing demand for our products and services; (m) the effects on our operations resulting from labor-related issues, such as strikes, unsuccessful union negotiations and other workforce disruptions; (n) the possibility of economic downturns and recessions, which could negatively impact our business by reducing consumer and Customer spending. Unless legally required, STERIS does not undertake to update or revise any

forward-looking statements even if events make clear that any projected results, express or implied, will not be realized.

The following table presents a financial measure which is considered to be "non-GAAP financial measures" under Securities Exchange Commission rules. Free cash flow is defined by the Company as cash flows from operating activities less purchases of property, plant, equipment and intangibles (capital expenditures) plus proceeds from the sale of property, plant, equipment and intangibles. The Company uses free cash flow as a measure to gauge its ability to pay cash dividends, fund growth outside of core operations, fund future debt principal repayments, and repurchase shares. STERIS's calculation of free cash flows may vary from other companies.
