According to the complaint, on September 19, 2022, in a lawsuit arising from Sotera’s emissions of the hazardous gas Ethylene Oxide (“EtO”), an Illinois state court jury found Sotera liable for the plaintiff’s cancer. Specifically, the jury awarded the plaintiff $363 million in damages, including $38 million in compensatory damages and $325 million in punitive damages. Further, according to the complaint, the jury cited “willful and wanton” misconduct by Sotera and its Sterigenics business in not preventing toxic EtO emissions and in failing to warn about the severe health hazard posed by the Company’s Illinois facility. 

Following this news, Sotera’s stock price fell $4.90 per share, or 33.3%, to close at $9.83 per share on September 19, 2022.
