Contingencies

9. 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 record a liability for such contingencies to the extent we conclude that their occurrence is both probable and estimable and believe we have adequately reserved for our current litigation and claims that are probable and estimable. In the event that the estimate of a probable loss is a range and no amount within the range is more likely, we accrue the minimum amount of the range. We consider many factors in making these assessments, including the professional judgment of experienced members of management and our legal counsel. We have made estimates as to the likelihood of unfavorable outcomes and the amounts of such potential losses. Further, we believe that the ultimate outcome of 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. For certain types of claims, we presently maintain insurance coverage for bodily injury and third party property damage and other liability coverages in amounts and with retentions and 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. We record expected recoveries under applicable contracts when we are assured of recovery.

Civil, criminal, regulatory or other proceedings involving our products or services, including the matters discussed herein, 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.

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.

In addition, the Company may pursue opportunities to recover amounts previously paid in connection with certain legal or regulatory matters, tariffs or similar governmental charges. During the three months ended June 30, 2026, the Company received $3.9 million related to amounts previously paid pursuant to the International Economic Emergency Powers Act ("IEEPA"), consisting of $3.7 million of refunds recorded in Cost of product revenues and $0.2 million of interest recorded in Interest and miscellaneous income. As of June 30, 2026, approximately $23 million of IEEPA tariffs have not yet been refunded, and no financial statement impact has been recognized with respect to these amounts.

Illinois EO Litigation Settlement

A subsidiary of the Company was sued in Illinois state court by individual plaintiffs who worked or resided 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 filed separate suits in which each alleged that they were diagnosed with one or more types of cancer, allegedly resulting from exposure to EO emissions from the facility into the ambient air.

On March 3, 2025, the Company entered into binding confidential term sheets ("Term Sheets") with plaintiffs’ counsel, as well as settlement agreements with several plaintiffs in cases which were at the time scheduled for trial in fiscal 2026. On October 29, 2025, the Company entered into binding confidential settlement agreements ("Settlement Agreements") with plaintiffs' counsel, containing terms and provisions consistent with the Term Sheets.

Pursuant to the Settlement Agreements, the Company agreed to pay up to $48.2 million to settle claims. We recorded a charge for this amount in fiscal 2025, and the remaining liability is included in the "Accrued expenses and other" line within our Consolidated Balance Sheets. None of the Settlement Agreements are an admission of liability or that emissions from the

Waukegan, Illinois facility ever posed a safety hazard to the people who live or work in the surrounding areas. The Settlement Agreements established a claims administration process that includes guidelines and procedures for administering individual settlements.

Subsequent to quarter-end, the Company made payments, consistent with amounts previously accrued, pursuant to the Settlement Agreements. As of July 31, 2026, substantially all payment obligations of the Company under the Settlement Agreements have been satisfied, and the claims administration process has been largely completed. Accordingly, substantially all of the personal injury claims subject to the Settlement Agreements have been dismissed with prejudice.

Additional Information

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 8 to our consolidated financial statements titled, “Income Taxes” in this Quarterly Report on Form 10-Q.
