Sotera Health Class Action Lawsuit Submission Form

The filed complaint alleges that Sotera Health Company made materially false and/or misleading statements and/or failed to disclose that:

1) long before the Company’s initial public offering, Sotera’s executives and controlling shareholders knew of the significant health risks associated with exposure to elevated levels of Ethylene Oxide (“EtO”); 2) despite that knowledge, Sotera failed to employ adequate and effective emissions control systems at its sterilization facilities and often subverted whatever control systems the Company did have; 3) these failures and subversions allowed dangerous amounts of toxic EtO fumes to pollute the air surrounding those facilities and exposed people living in the adjacent communities to significantly increased cancer risks; 4) even after Sotera’s closure of its Illinois EtO processing plant, the Company continued to operate multiple sterilization facilities that emitted dangerous levels of EtO; and 5) to the extent that the Company purported to warn of liability risks from the EtO cancer-related lawsuits, Sotera failed to disclose the true extent of those risks by withholding information from investors regarding the inadequacy or subversion of its EtO emissions control systems.
