Our Businesses Sterilization Services Our sterilization services business is comprised of Sterigenics and Nordion. Sterigenics We are a leading global provider of outsourced terminal sterilization and irradiation services and have provided sterilization services for over 90 years. We offer a globally integrated platform for our customers in the medical device, pharmaceutical, food safety, and advanced applications markets, with facilities strategically located to be convenient to our customers’ manufacturing sites and distribution hubs or routes. Terminal sterilization is the process of sterilizing a product in its final packaging; it is an essential, and often government-mandated, last step in the manufacturing process of healthcare products before they are shipped to end-users. The products that we sterilize include procedure kits and trays, implants, syringes, catheters, wound care products, medical protective barriers, including personal protective equipment (“PPE”), laboratory products and pharmaceuticals. Sterilization Services We offer our customers a complete range of terminal sterilization services, primarily using the three major commercial terminal sterilization technologies: gamma irradiation, EO processing and E-beam irradiation. We continue to invest in and develop our capabilities and our current methods of sterilization and we continue to explore new alternative modalities and technologies. We provide gamma irradiation services at 23 of our facilities, EO processing services at 17 of our facilities and electron beam (“E-beam”) irradiation services at eight of our facilities. We also invest in alternative modalities to serve our customers. X-ray irradiation is a process in which products, such as medical devices and labware, are exposed to machine-generated radiation in the form of X-rays for the purpose of sterilization and decontamination. Final qualification is currently underway for a new X-Ray facility adjacent to an existing gamma facility. We are also investing in NO2-based sterilization and other technologies, which have been effective in the sterilization of prefilled syringes, drug-device combination products and custom implants. Sterilization Applications Sterigenics primarily provides sterilization services for medical device manufacturers and the pharmaceutical industry and also provides microbial reduction services for the food industry. Additionally, Sterigenics provides various advanced applications for other organizations and companies, including the USPS and semiconductor manufacturers. Our customers determine the sterilization method that meets the needs of their products and requirements of regulators and we deliver sterilization services according to their customer-specific protocols. In most cases, customers are serviced by more than one facility. 6 Table of Contents • Medical device sterilization .…
