On December 17, 2020, Sotera Health Company (the “Company”), Sotera Health Holdings, LLC (“SHH”), the Incremental Amendment Revolving Lenders party thereto, Jefferies Finance LLC, as First Lien Administrative Agent (the “Administrative Agent”), each Issuing Bank and the other Loan Parties, entered into the Incremental Facility Amendment (the “Amendment”) to the First Lien Credit Agreement dated as of December 13, 2019 by and among the Company, SHH, the Lenders from time to time party thereto and the Administrative Agent (the “Credit Agreement”).

Among other changes, the Amendment provides (i) for an Incremental Revolving Commitment Increase (as defined in the Credit Agreement) in an aggregate principal amount of $157,500,000 by the Incremental Amendment Revolving Lenders and (ii) that the Incremental Amendment Revolving Lenders shall also provide additional Letter of Credit Sublimits (as defined in the Credit Agreement) as part of the increased Revolving Commitments (as defined in the Credit Agreement). The Incremental Amendment Revolving Lenders are Citibank, N.A., Citizens Bank, N.A., Credit Suisse AG, Cayman Islands Branch, Goldman Sachs Bank USA, Jefferies Finance LLC, JPMorgan Chase Bank, N.A and Key Bank National Association. As of the effective date of the Amendment, the aggregate amount of the Lenders’ Revolving Commitments is $347,500,000.

The foregoing description of certain provisions of the Amendment and the underlying Credit Agreement do not purport to be complete and is qualified in its entirety by the full text of the Credit Agreement and the Amendment, which will be filed as an exhibit to the Company’s next Annual Report on Form 10-K.

On December 14, 2020 (the “Redemption Date”), SHH redeemed in full all of the $770,000,000 aggregate principal amount of its outstanding Senior Secured Second Lien Floating Rate Notes due 2027 (the “Notes”) at a redemption price equal to 102.000% of the principal amount of the Notes, plus accrued and unpaid interest to, but not including, the Redemption Date of $14,437,500 (the “Redemption Payment”). The total Redemption Payment for the Notes was $799,837,500.

The Notes were issued pursuant to an indenture, dated December 13, 2019, among SHH, the Company, the intermediate parents and subsidiary note parties party thereto (the “Notes Guarantors”) and Wilmington Trust, National Association, as trustee (as amended, the “Indenture”). Following the deposit of the Redemption Payment, the Indenture and the related security documents were satisfied and discharged in accordance with the terms of the Indenture. As a result of the satisfaction and discharge of the Indenture and the release of all of the liens on the collateral securing the Notes, the Company, SHH and the Notes Guarantors have been released from their obligations with respect to the Indenture, the related security documents and the Notes, except with respect to those provisions of the Indenture that, by their terms, survive the satisfaction and discharge of the Indenture.

The information contained in Item 1.01 of this Current Report on Form 8-K above is incorporated herein by reference.

On December 18, 2020, the Company issued a press release (the “Press Release”) announcing entry into the Amendment. A copy of the Press Release is filed as Exhibit 99.1 and is incorporated herein by reference.

The information in this Item 7.01, including Exhibit 99.1, is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to liability under that section, and shall not be deemed to be incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, unless expressly incorporated by specific reference in such filing.

Because the Company has not previously filed a proxy statement or held an annual meeting of stockholders since becoming a publicly traded company, the Company is disclosing deadlines for certain notices under SEC rules and its amended and restated bylaws in connection with its 2021 annual meeting of stockholders, which the Company intends to hold on May 27, 2021.

To be considered timely, a proposal submitted for inclusion in the Company’s 2021 annual meeting proxy materials pursuant to Rule 14a-8 under the Exchange Act must be submitted to the Company’s principal executive office, to the attention of the corporate secretary, and received on or before January 8, 2021.

To be considered timely under the Company’s amended and restated bylaws, notice of a nomination for election to the board or notice of a proposal or other business submitted other than pursuant to Rule 14a-8 must be received by the corporate secretary at the Company’s principal executive office no earlier than the open of business on January 28, 2021 and no later than the close of business on February 26, 2021.
