Sotera Health sterilizes medical devices and tests products for safety—think of it as the invisible gatekeeper ensuring your pacemaker or syringe is germ-free before it reaches a hospital.
Sterilization services drive revenue, with annual sales growing from USD 1.05B to USD 1.16B over three years. Gross margins hover around 55%, and operating margins improved to 33.75% in 2025, indicating recurring, high-margin contract work.
Regulatory approvals and long-term contracts with medical device giants like Medtronic and Abbott create switching costs, but ethylene oxide emission concerns and potential regulatory tightening could erode this advantage.
