Item 1.01 Entry into a Material Definitive Agreement. New Revolving Credit Agreement On November 4, 2026, STERIS plc (“STERIS”), STERIS Corporation (“Corporation”), STERIS Limited (“Limited”) and STERIS Irish FinCo Unlimited Company (“FinCo”), each as a borrower and guarantor, entered into a credit agreement (the “New Revolving Credit Agreement”) with various financial institutions and each of J.P. Morgan SE and JPMorgan Chase Bank, N.A., as administrative agents, providing for a $1,600 million revolving credit facility (the “Revolver”), which replaces the existing credit agreement, dated as of October 7, 2024 (the “Existing Revolving Credit Agreement”). The proceeds of the Revolver may be used for revolving credit borrowings, swingline borrowings and letters of credit, with sublimits for such swingline borrowings and letters of credit. On the closing date for the New Revolving Credit Agreement, no borrowings were incurred to refinance and replace the Existing Revolving Credit Agreement. The Revolver permits an incremental increase of commitments available thereunder in an amount not to exceed $800 million, subject to certain customary conditions. The Revolver matures on November 4, 2031 and all unpaid borrowings, together with accrued and unpaid interest thereon, are repayable on that date. The Revolver bears interest from time to time, at either the Base Rate or the Relevant Rate, in each case as defined in and calculated under and as in effect from time to time under the New Revolving Credit Agreement, plus the Applicable Margin, as defined in the New Revolving Credit Agreement. The Applicable Margin is determined based on the debt rating of STERIS. Interest on borrowings made at the Base Rate (“Revolver Base Rate Advances”) is payable quarterly in arrears. Interest
