Item 8.01. Other Events.
As previously disclosed, on October 16, 2023, two subsidiaries of Sotera Health Company, Sotera Health LLC and Sterigenics U.S., LLC (“Sterigenics” and, together with Sotera Health LLC, the “Settling Defendants”), entered into a binding settlement term sheet (the “Settlement Term Sheet”) to pay $35 million (the “Settlement Payment”) to resolve ethylene oxide (“EO”) exposure claims brought by 79 claimants (each a "Settling Plaintiff" and collectively the “Settling Plaintiffs”) arising from alleged emissions of EO from Sterigenics’ operations in Atlanta, Georgia (the “Covered Claims”). The Covered Claims comprise a lawsuit that was scheduled to begin trial in the State Court of Gwinnett County, Georgia in October 2023 and claims being pursued by the same plaintiff’s counsel on behalf of 78 other claimants.
The settlement contemplated by the Settlement Term Sheet was subject to the satisfaction of several conditions, including that 100% of the Settling Plaintiffs consent to their respective payment allocations. This condition has been satisfied within the opt-in period specified in the Settlement Term Sheet. One plaintiff is dismissing his claim with prejudice and the 78 others have executed settlement agreements consenting to their allocations of the Settlement Payment in return for dismissing their claims with prejudice.
Pursuant to an Amendment to Settlement Term Sheet executed on December 21, 2023 (the “Amendment to the Settlement Term Sheet”), Sterigenics will make the Settlement Payment by the later of January 5, 2024 or five business days after counsel for the Settling Plaintiffs has created a qualified settlement fund. The Settling Plaintiffs in three claims involving plaintiffs who are minors will move to dismiss their Covered Claims with prejudice within one day of obtaining trial court approval of the settlement as required by Georgia law. All other Settling Plaintiffs will move to dismiss their Covered Claims with prejudice within three business days of Sterigenics making the Settlement Payment. Barring unforeseen developments, the Settling Defendants expect for the settlement to be completed and the 79 cases to be dismissed with prejudice in January 2024.
The Settling Defendants deny any liability for the Covered Claims and, per their express terms, neither the Settlement Term Sheet, the Amendment to the Settlement Term Sheet nor the settlement agreements with the Settling Plaintiffs constitute or are to be construed as an admission of liability or that the Settling Defendants or any related parties engaged in any wrongful, tortious, or unlawful activity or that the use and/or emission of EO from Sterigenics’ operations in Atlanta, Georgia, posed any safety hazard to the surrounding communities.
For more information about the settlement of the Covered Claims or about EO-related lawsuits more generally, please see our most recent Annual Report on Form 10-K and Quarterly Report on Form 10-Q and the Latest Updates in the EO section of our Investor Relations website at https://investors.soterahealth.com/latest-updates.
