Item 1.01.Entry into a Material Definitive Agreement.

On April 30, 2026, Modine Manufacturing Company (the “Company”) and Airedale International Air Conditioning Limited, as borrowers (collectively, the “Borrowers”), entered into Amendment No. 2 (the “Amendment”) to the Sixth Amended and Restated Credit Agreement, dated as of July 10, 2025 (as previously amended, the “Credit Agreement”), by and among the Borrowers, the lenders party thereto, and JPMorgan Chase Bank, N.A., as administrative agent.

The Amendment modifies the Credit Agreement to, among other things, (i) permit the separation, disposition and spin-off of the Company’s Performance Technologies business and the related transactions contemplated by that certain Agreement and Plan of Merger, dated January 29, 2026 (collectively, the “PT Transaction”), and (ii) provide for the incurrence of indebtedness by a newly formed subsidiary in connection with the PT Transaction and the use of the proceeds thereof.

In connection with the foregoing, the Amendment (a) adds definitions and related provisions pertaining to the PT Transaction, including provisions relating to a newly-formed escrow subsidiary that may incur indebtedness, the proceeds of which are to be held in escrow pending consummation of the PT Transaction, (b) revises certain negative covenants to permit investments, restricted payments, asset transfers and affiliate transactions undertaken in connection with the PT Transaction, and (c) provides for a mandatory prepayment of loans under the Credit Agreement with 100% of the net proceeds of such indebtedness upon release from escrow or otherwise in connection with the PT Transaction, subject to specified application mechanics.

The foregoing description of the material terms of the Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Amendment, which is attached hereto as Exhibit 4.1 and is incorporated by reference herein.
