STERIS Announces Financial Results for Fiscal 2025 Third Quarter

DUBLIN, IRELAND - (February 5, 2025) - STERIS plc (NYSE STE) ("STERIS" or the "Company") today announced financial results for its fiscal 2025 third quarter ended December 31, 2024. Total revenue from continuing operations for the third quarter of fiscal 2025 increased 6% to $1.4 billion compared with $1.3 billion in the third quarter of fiscal 2024. Constant currency organic revenue from continuing operations for the third quarter also increased 6%.

"We are pleased with our results through the first nine months of the fiscal year," said Dan Carestio, President and CEO of STERIS. "We are updating our outlook primarily to reflect a significant shift in foreign currency based on forward rates through March 31, 2025. We appreciate the efforts of our global Associates who continue to focus on our Customers and look forward to another year of solid performance."

Third Quarter Results from Continuing Operations

As reported, net income for the third quarter was $173.6 million or $1.75 per diluted share, compared with net income of $148.4 million or $1.49 per diluted share in the third quarter of fiscal 2024. Adjusted net income for the third quarter of fiscal 2025 was $229.1 million or $2.32 per diluted share, compared with the previous year's third quarter of $207.6 million or $2.09 per diluted share.

Healthcare revenue as reported grew 7% in the quarter to $976.0 million compared with $916.2 million in the third quarter of fiscal 2024. This performance reflected 9% improvement in consumable revenue, 13% growth in service revenue, and a 5% decline in capital equipment revenue. Constant currency organic revenue also increased 7% for the quarter compared with the prior year. Healthcare operating income was $246.9 million compared with $223.9 million in last year's third quarter. The increase in operating income was primarily due to improved volume, price and productivity.

Fiscal 2025 third quarter revenue for Applied Sterilization Technologies (AST) increased 10% as reported to $258.1 million compared with $234.9 million in the same period last year. This performance reflected 10% growth in service revenue and a 5% decline in capital equipment revenue. Constant currency organic revenue in the quarter also increased 10%. Segment operating income was $115.8 million in the third quarter of fiscal 2025, compared with operating income of $105.2 million in the same period last year. The operating income increase compared with the prior year primarily reflects improved volume and price.

Life Sciences third quarter revenue as reported decreased 7% to $136.4 million compared with $146.6 million in the third quarter of fiscal 2024, primarily due to the divestiture of the CECS business on April 1, 2024 and a decline in capital equipment revenue. This performance reflected 14% growth in consumable revenue offset by a 31% decline in capital equipment revenue and 12% decline in service revenue. Constant currency organic revenue decreased 1% in the quarter compared with the prior year. Reflecting improvement in mix and price, operating income increased to $58.1 million in the third quarter of fiscal 2025 compared with $56.7 million in the prior year's third quarter.

Net cash provided by operations for the first nine months of fiscal 2025 was $887.3 million, compared with $718.5 million in fiscal 2024. Free cash flow for the first nine months of fiscal 2025 was $588.1 million compared with $457.0 million in the prior year period. The increase in free cash flow during the period was driven primarily by improved working capital.

Fiscal 2025 Outlook Updated

For fiscal 2025, the Company now expects as reported revenue to increase approximately 6% compared with prior expectations of 6.5% to 7.5%. This change is primarily due to currency, as forward rates through March 31, 2025, are now expected to be unfavorable to revenue in fiscal 2025, as well as lower than anticipated revenue for capital equipment in the Healthcare segment. Constant currency organic revenue from continuing operations is also now anticipated to be approximately 6%, compared with prior expectations of 6% to 7%. Adjusted earnings per diluted share from continuing operations is anticipated to be in the range of $9.05 to $9.15 compared with prior expectations of $9.05 to $9.25, mainly driven by an approximately ten cent negative impact from currency. The fiscal 2025 outlook assumes an effective tax rate of approximately 23%. Capital expenditures are anticipated to be approximately $360 million and free cash flow is expected to be approximately $700 million. This outlook does not reflect any potential impact from new tariffs.

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.
