On October 7, 2024, STERIS plc (“Parent”), STERIS Corporation ("Corporation"), STERIS Limited ("Limited"), and STERIS Irish FinCo Unlimited Company (“FinCo”), each as a borrower and guarantor, entered into a credit agreement with various financial institutions as lenders, and JPMorgan Chase Bank, N.A., as administrative agent (the “Revolving Credit Agreement”) providing for a $1,100.0 million revolving credit facility (the “Revolving Credit Facility”), which replaced a prior credit agreement, dated as of March 19, 2021.

The Revolving Credit Agreement provides for revolving credit borrowings, swing line borrowings and letters of credit, with sublimits for swing line borrowings and letters of credit. The Revolving Credit Agreement may be increased in specified circumstances by up to $625.0 million in the discretion of the lenders. The Revolving Credit Agreement matures on the date that is five years after October 7, 2024, and all unpaid borrowings, together with accrued and unpaid interest thereon, are repayable on that date. The Revolving Credit Facility bears interest from time to time, at either the Base Rate or the Relevant Rate, as defined in and calculated under and as in effect from time to time under the Revolving Credit Agreement, plus the Applicable Margin, as defined in the Revolving Credit Agreement. The Applicable Margin is determined based on the Debt Rating of Parent, as defined in the Revolving Credit Agreement. Base Rate Advances are payable quarterly in arrears and Term Benchmark Advances are payable at the end of the relevant interest period therefor, but in no event less frequently than every three months. Swingline borrowings bear interest at a rate to be agreed by the applicable swingline lender and the applicable borrower, subject to a cap in the case of swingline borrowings denominated in U.S. Dollars equal to the Base Rate plus the Applicable Margin for Base Rate Advances plus the Facility Fee. There is no premium or penalty for prepayment of Base Rate Advances, but prepayments of Term Benchmark Advances are generally subject to a breakage fee. Advances may be extended

in U.S. Dollars or in specified alternative currencies (“Alternative Currency Advances”). Alternative Currency Advances are limited in the aggregate to the equivalent of $625.0 million.
