Management Comments

• "We delivered more than 6% top-line growth for the quarter, supported by strong volume performance at Sterigenics."

Industry Context

The strong performance, particularly in sterilization solutions (Sterigenics) and lab testing (Nelson Labs), indicates a robust demand for mission-critical healthcare services. The company's ability to achieve significant margin expansion at Nelson Labs despite a revenue decline in expert advisory services suggests effective operational optimization within the lab testing segment. The overall growth in net revenues and Adjusted EBITDA, coupled with an improved leverage ratio, positions Sotera Health favorably within the healthcare services sector, which continues to benefit from ongoing demand for medical device and pharmaceutical support services.

Comparison to Industry Standards

• The filing does not provide specific comparable companies, projects, or results to assess against global benchmarks. However, the reported growth rates and margin expansion suggest a strong performance within the specialized healthcare services sector.

Legal Proceedings

• The company incurred approximately $34 million in Q2 2025 related to a pending and previously disclosed settlement of ethylene oxide (EO) claims against Sterigenics.
• For the first six months of 2025, the company incurred approximately $31 million and $34 million in pending and previously disclosed settlements related to EO claims against Sterigenics.
