STERIS provides infection prevention and sterile processing products and services for healthcare and life sciences markets. The company helps hospitals, medical device manufacturers, and pharmaceutical companies maintain sterile environments and instruments. STERIS operates through three segments: Healthcare, Applied Sterilization Technologies (AST), and Life Sciences. The Healthcare segment sells capital equipment like sterilizers and washers, alongside consumables and maintenance services to hospitals and surgery centers. The AST segment provides contract sterilization services to medical device and pharmaceutical manufacturers through a global network of facilities using gamma, electron beam, X-ray, and ethylene oxide gas. The Life Sciences segment offers specialized cleaning chemistries and equipment for aseptic pharmaceutical manufacturing environments. STERIS relies on a business model centered on recurring revenue from consumables and services, which track surgical procedure volumes. Capital equipment sales drive a long-term installed base that generates ongoing demand for maintenance and cleaning chemistries. STERIS grows by expanding its AST sterilization capacity, particularly in X-ray technology, and increasing its market share in healthcare through a portfolio of integrated workflow solutions. The company also pursues geographic expansion in EMEA and tuck-in acquisitions to add new products and capabilities.
