Item 7.01. Regulation FD Disclosure.
Entry into Master Settlement Agreements
As previously reported on January 9, 2023, two subsidiaries of Sotera Health Company (the “Company”), Sotera Health LLC and Sterigenics U.S., LLC (“Sterigenics” and, together with Sotera Health LLC, the “Settling Defendants”), entered into binding term sheets (the “Term Sheets”) with a committee (the “Plaintiffs’ Executive Committee”) of 7 of the 20+ law firms (“Plaintiffs’ Counsel”) representing over 870 claimants who have filed and unfiled ethylene oxide (“EO”) exposure claims against the Settling Defendants (together, the “Eligible Claimants”) related to Sterigenics’ former facility in Willowbrook, Illinois. The Term Sheets established an agreed path to final settlement of all claims that have been alleged or could have been alleged by Eligible Claimants related to or arising from alleged emissions of EO from Sterigenics’ operations in or around Willowbrook, Illinois and related claims that have been or could have been alleged by Eligible Claimants seeking to challenge any transfer of assets to or from the Company, its subsidiaries and certain affiliates to any other entity or person (the “Covered Claims”), subject to the satisfaction or waiver of various conditions. Copies of the Term Sheets were filed as exhibits to the Company’s Annual Report on Form 10-K for the period ended December 31, 2022.
The parties to the Term Sheets agreed to draft and execute full settlement agreements and, on March 28, 2023, the Settling Defendants entered into definitive Master Settlement Agreements with the Plaintiffs’ Executive Committee (the “Master Settlement Agreements”). The Master Settlement Agreements’ scope and terms and conditions are consistent in all material respects with those of the Term Sheets and effect the agreed upon path to settlement laid out therein.
Although the final settlement of claims contemplated under the Master Settlement Agreements may not occur or may not occur for all Eligible Claimants for any number of reasons as previously disclosed, including a failure to obtain the required opt-in consents, the Plaintiffs’ Executive Committee and Settling Defendants are endeavoring to complete the settlement process by August 2023. To this end, the Settling Defendants are scheduled to fund escrow accounts for the settlement payments in the amount of $408 million on May 1, 2023. If the Plaintiffs’ Executive Committee determines that more time is required to complete the opt-in process and/or the Settling Defendants determine that more time is required to complete their evaluation of any opt-outs from the settlement, the Master Settlement Agreements provide for modest extensions of deadlines that could result in modest delays to the completion of the settlement process.
The foregoing description of the Master Settlement Agreements is qualified in its entirety by reference to the text of the Master Settlement Agreements, redacted copies of which will be filed as exhibits to the Company’s Quarterly Report on Form 10-Q for the period ended March 31, 2023. For more information about the prospective settlement of the EO-related lawsuits pending in Cook County, Illinois, please see our most recent Annual Report on Form 10-K and our website at
