Sotera Health is a high-quality healthcare sterilization business with 123% free cash flow conversion, a Piotroski F-Score of 8/9, and three consecutive earnings beats, but single-supplier dependency on one ethylene oxide source and high leverage at 3.6x debt-to-equity constrain near-term entry.

About Sotera Health Company
About Sotera Health Company
Sotera Health operates 62 sterilization and lab testing facilities across 13 countries, serving over 2,000 Sterigenics customers and approximately 3,000 Nelson Labs customers. More than 90% of Sterigenics revenues and approximately 90% of Nordion revenues in 2025 were from multi-year contracts, with Sterigenics achieving 100% renewal rates with its top 10 customers for more than five consecutive years. No single customer accounted for more than 10% of total revenues across either Sterigenics or Nelson Labs.
Sotera Health earns per-service fees through three business units. Sterigenics provides gamma irradiation (23 facilities), EO processing (17 facilities), and E-beam irradiation (8 facilities) services to medical device, pharmaceutical, food, and advanced applications customers. Nordion sells Co-60 radioactive isotope and gamma irradiation systems; Co-60 is sourced from contracts with three nuclear reactor operators covering 13 reactors at five Canadian and Russian generating stations, extending to dates between 2026 and 2064. Russian reactors contribute approximately 20% of long-term Co-60 supply and may reach roughly 50% in certain years due to variability at other reactor sites. EO supply in the United States comes from a single supplier with redundant production facilities. Applied Sterilization Technologies, a segment of STERIS plc, is the main global competitor to Sterigenics. Nelson Labs provides over 900 microbiological and analytical chemistry test types.

Sotera Health faces an EO litigation overhang that could weigh on financial results. The company is currently defending lawsuits in California, Georgia, Illinois, and New Mexico alleging personal injury and property devaluation related to EO emissions from current and former facilities. Environmental liability insurance explicitly excludes EO claims, meaning settlements or adverse judgments would be largely uninsured. Compounding this, the single ocean carrier licensed to transport Co-60 from Russia to North America holds logistics licenses subject to renewal in 2026 and 2027 under the current sanctions framework — if those licenses cannot be renewed, Co-60 supply from Russian reactors could be disrupted.
