Sotera Health (SHC)

Sotera Health operates through three main businesses: Sterigenics, Nordion, and Nelson Labs. Sterigenics is the largest contributor to revenue and provides outsourced terminal sterilisation and irradiation services. Its technologies include gamma irradiation, ethylene oxide processing, and electron beam irradiation, each used for different product types, packaging formats, and sterilisation requirements. These services are especially important for medical devices and healthcare products that cannot be sterilised effectively by manufacturers in-house or by conventional methods.

Nordion supplies products and services connected to gamma technologies, including cobalt-60, a radioisotope widely used in industrial sterilisation. Nelson Labs provides microbiological and analytical testing, helping customers assess sterility, biocompatibility, toxicology, packaging integrity, and other quality attributes. Together, the three segments give Sotera Health a broad role across the product safety chain, from testing and validation to commercial sterilisation.

The company serves customers in the United States, Canada, Europe, and other international markets, with the United States representing its largest geographic source of revenue. Sotera Health’s business is shaped by healthcare production volumes, regulatory standards, outsourcing trends, and demand for safe, sterile products. Its services are typically mission-critical because many medical and pharmaceutical products cannot be distributed without validated sterilisation or testing evidence.
