On November 13, 2025, Iron Mountain Incorporated (the “Company”), Iron Mountain Information Management, LLC (“IMIM”), and certain other subsidiaries of the Company entered into an Amendment No. 7 (the “Amendment”) to the Company’s Credit Agreement, dated as of June 27, 2011 (as previously amended, restated, amended and restated, supplemented or otherwise modified from time to time, the “Credit Agreement”; capitalized terms used but not defined herein shall have the meanings assigned therefor in the Credit Agreement), by and among, inter alia, the Company, IMIM, the other borrowers party thereto, the lenders party thereto, JPMorgan Chase Bank, N.A., as the administrative agent, and JPMorgan Chase Bank, N.A., Toronto Branch, as Canadian administrative agent. Pursuant to the Amendment, IMIM incurred incremental term loans in an aggregate principal amount of $200,000,000 (the “Incremental Term B Loans”) that are fungible for all purposes with the existing Amendment No. 1 Incremental Term B Loans due 2031 outstanding under the Credit Agreement (the “Existing Term B Loans”).
The terms applicable to the Incremental Term B Loans, including the interest rate and maturity applicable thereto, are the same as those applicable to the Existing Term B Loans.
Except as amended by the Amendment, the terms of the Credit Agreement remain in full force and effect. All other material provisions of the Credit Agreement remain materially unchanged. As of November 13, 2025, after giving effect to the Amendment and the transactions contemplated therein, the Company had $2,036,677,512 of outstanding borrowings of Amendment No. 1 Incremental Term B Loans under the Credit Agreement.
The above description of the Amendment is not complete and is subject to and qualified in its entirety by reference to the Amendment and the Credit Agreement, a copy of which is attached as Exhibit 10.1 to this report and incorporated herein by reference. The representations and warranties contained in the Amendment were made only for purposes of that amendment and as of the dates specified therein; were solely for the benefit of certain parties to the Amendment; and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors should not rely on the representations and warranties or any description thereof as characterizations of the actual state of facts or condition of the Company, IMIM and its subsidiaries. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Amendment, which subsequent information may or may not be fully reflected in public disclosures by the Company.
