Business Segment Information
13. BUSINESS SEGMENT INFORMATION
We operate and report our financial information in three reportable business segments: Healthcare, AST, and Life Sciences. Previously, we had four reportable business segments, however, as a result of the fiscal 2025 divestiture of our Dental segment, Dental is presented as discontinued operations. The Dental segment previously met the criteria for a reportable segment and has been removed from segment disclosures for all periods presented following its classification as discontinued operations. Historical information has been retrospectively adjusted to reflect these changes for comparability, as required. For more information, refer to Note 4 titled, "Discontinued Operations." Non-allocated operating costs that support the entire Company and items not indicative of operating trends are excluded from segment operating income. These costs include expenses
primarily include executive management costs, certain centralized finance, legal, human resources, information technology functions, global systems costs, and other corporate‑level activities that are not directly attributable to the reportable segments.
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, instruments, and capital equipment infrastructure used primarily in operating rooms, ambulatory surgery centers, endoscopy suites, and other procedural areas.
Our AST segment supports medical device and pharmaceutical manufacturers through a global network of contract sterilization and laboratory testing facilities, and integrated sterilization equipment and control systems. 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 designed to support biopharmaceutical and medical device research and manufacturing facilities, in particular those focused on aseptic manufacturing. Our portfolio includes a full suite of capital equipment, consumable products, equipment maintenance and specialty services.
Our chief operating decision maker ("CODM") is our President and Chief Executive Officer ("CEO"). The CEO is responsible for performance assessment and resource allocation. The CEO regularly receives discrete financial information about each reportable segment and uses this information to assess performance and allocate resources. This information includes Revenues and Cost of revenues; Selling, general, and administrative expenses; and Research and development expenses for each reportable segment.
Segment operating income represents revenues less cost of revenues, selling, general and administrative expenses, and research and development expenses that are directly attributable to the segment. Segment operating income excludes amortization of acquired intangible assets, acquisition and integration‑related charges, restructuring costs, costs incurred in tax restructuring initiatives, and other items that management does not consider indicative of segment operating performance. These excluded items are reported within the tables below to reconcile segment operating income to income from operations.
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 years ended March 31, 2026, revenues from a single Customer did not represent ten percent or more of the Healthcare, AST or Life Sciences segment revenues.
Information regarding our segments is presented in the following tables.

Assets include the current and long-lived assets directly attributable to the segment based on the management of the location or on utilization. Certain corporate assets were allocated to the reportable segments based on revenues. Assets attributed to sales and distribution locations are only allocated to the Healthcare and Life Sciences segments.
Individual facilities, equipment, and intellectual properties are utilized by both the Healthcare and Life Sciences segments at varying levels over time. As a result, an allocation of total assets, capital expenditures, and depreciation and amortization is not meaningful to the individual performance of the Healthcare and Life Sciences segments. Therefore, their respective amounts are reported together.
