STERIS plc makes sterilization and infection prevention equipment and services used by hospitals, medical device manufacturers and pharmaceutical companies to sterilize surgical instruments and prevent the spread of infections in healthcare settings. Its equipment and services are essential to hospital operations, since surgical instruments must be properly sterilized between uses to prevent patient infections, making STERIS's products a non-discretionary part of healthcare facility operations. The company also provides sterilization services to medical device and pharmaceutical manufacturers, helping ensure their products meet regulatory sterility requirements before reaching healthcare providers and patients. STERIS's revenue is tied to overall healthcare facility spending and surgical procedure volumes, along with medical device and pharmaceutical manufacturing activity that drives demand for its contract sterilization services.
