A. CREDIT AGREEMENT
Our credit agreement (the "Credit Agreement") consists of a revolving credit facility (the "Revolving Credit Facility"), a term loan A facility (the "Term Loan A") and a term loan B facility (the "Term Loan B").
During the year ended December 31, 2025, we took the following actions regarding our Credit Agreement:
•On June 18, 2025, we amended the Credit Agreement, which resulted in:
◦an increase in the principal amount of the Term Loan A from $218,750 to $500,000.
•On November 13, 2025, we amended the Credit Agreement, which resulted in:
◦an increase in the principal amount of the Term Loan B from approximately $1,836,700 to $2,036,700.
In connection with the November 13, 2025 amendment, we paid original issue discount fees of approximately $1,750.
The Revolving Credit Facility enables IMI and certain of its subsidiaries to borrow an aggregate outstanding amount not to exceed $2,750,000 in United States dollars and (subject to sublimits) Canadian dollars. Additionally, the Credit Agreement permits us to incur incremental indebtedness thereunder by adding new term loans or revolving loans or by increasing the principal amount of any existing loans thereunder. The Revolving Credit Facility and the Term Loan A are scheduled to mature on March 18, 2030, at which point all obligations become due. The Term Loan A, which was fully drawn as of December 31, 2025, is to be paid in quarterly installments in an amount equal to approximately $6,250 per quarter. The Term Loan B is scheduled to mature on January 31, 2031, at which point all obligations become due. The Term Loan B, which was fully drawn as of December 31, 2025, is to be paid in quarterly installments in an amount equal to approximately $5,182 per quarter.
IMI and certain subsidiaries of IMI that represent the substantial majority of our operations in the United States, Canada and the United Kingdom guarantee all obligations under the Credit Agreement. The interest rate on borrowings under the Revolving Credit Facility varies depending on our choice of interest rate benchmark and currency options, plus an applicable margin, which varies based on our consolidated leverage ratio. The Term Loan A and the Term Loan B bear interest at the SOFR plus 1.75% and the SOFR plus 2.00%, respectively. Additionally, the Credit Agreement requires the payment of a commitment fee on the unused portion of the Revolving Credit Facility, which fee ranges from 0.2% to 0.3% based on our consolidated leverage ratio.
As of December 31, 2025, we had $751,500, $487,500 and $2,031,495 outstanding under the Revolving Credit Facility, the Term Loan A and the Term Loan B, respectively. As of December 31, 2025, we had various outstanding letters of credit totaling $12,398 under the Revolving Credit Facility. The remaining amount available for borrowing under the Revolving Credit Facility as of December 31, 2025, which is based on IMI’s leverage ratio, the last 12 months' earnings before interest, taxes, depreciation and amortization and rent expense ("EBITDAR"), other adjustments as defined in the Credit Agreement and current external debt, was $1,986,102 (which amount represents the maximum availability as of such date). Available borrowings under the Revolving Credit Facility are subject to compliance with our indenture covenants as discussed below. The weighted average interest rates in effect under the Revolving Credit Facility as of December 31, 2025 and 2024 were 5.7% and 6.3%, respectively. The interest rates in effect under the Term Loan A as of December 31, 2025 and 2024 were 5.5% and 6.1%, respectively. The interest rates in effect under the Term Loan B as of December 31, 2025 and 2024 were 5.8% and 6.4%, respectively.

D. AUSTRALIAN DOLLAR TERM LOAN
Iron Mountain Australia Group Pty, Ltd., a wholly-owned subsidiary of IMI, has an AUD term loan (the "AUD Term Loan"). On June 25, 2025, we amended the AUD Term Loan, which resulted in:

E. UK REVOLVING CREDIT FACILITY
IM UK and Iron Mountain (UK) Data Centre Limited, wholly-owned subsidiaries of IMI (collectively, the "UK Borrowers"), have a British pounds sterling Revolving Credit Facility (the "UK Revolving Credit Facility"). The maximum amount permitted to be borrowed under the UK Revolving Credit Facility is 140,000 British pounds sterling. We have the option to request additional commitments of up to 125,000 British pounds sterling, subject to conditions specified in the UK Revolving Credit Facility. IMI and subsidiaries of IMI that represent the substantial majority of our operations in the United States and the United Kingdom guarantee all obligations under the UK Revolving Credit Facility. The UK Revolving Credit Facility is secured by certain properties in the United Kingdom. The UK Revolving Credit Facility bears interest at the Sterling Overnight Index Average plus 2.0%. On July 11, 2025, the UK Borrowers amended the UK Revolving Credit Facility to extend the maturity date from September 24, 2026 to September 24, 2028. The UK Revolving Credit Facility was fully drawn as of December 31, 2025. The interest rate in effect under the UK Revolving Credit Facility was 5.8% and 7.0% as of December 31, 2025 and 2024, respectively. | MAXIMUM AMOUNT £140,000 OPTIONAL ADDITIONAL COMMITMENTS £125,000 5.8% Interest rate As of December 31, 2025 | ||||||||||||||||
F. ACCOUNTS RECEIVABLE SECURITIZATION PROGRAM
We participate in an accounts receivable securitization program (the "Accounts Receivable Securitization Program") involving several of our wholly-owned subsidiaries and certain financial institutions. Under the Accounts Receivable Securitization Program, certain of our subsidiaries sell substantially all of their United States accounts receivable balances to our wholly-owned special purpose entities, Iron Mountain Receivables QRS, LLC and Iron Mountain Receivables TRS, LLC (the "Accounts Receivable Securitization Special Purpose Subsidiaries"). The Accounts Receivable Securitization Special Purpose Subsidiaries use the accounts receivable balances to collateralize loans obtained from certain financial institutions. The Accounts Receivable Securitization Special Purpose Subsidiaries are consolidated subsidiaries of IMI. The Accounts Receivable Securitization Program is accounted for as a collateralized financing activity, rather than a sale of assets, and therefore: (i) accounts receivable balances pledged as collateral are presented as assets and borrowings are presented as liabilities on our Consolidated Balance Sheets, (ii) our Consolidated Statements of Operations reflect the associated charges for bad debt expense related to pledged accounts receivable (a component of selling, general and administrative expenses) and reductions to revenue due to billing and service related credit memos issued to customers and related reserves, as well as interest expense associated with the collateralized borrowings and (iii) receipts from customers related to the underlying accounts receivable are reflected as operating cash flows and borrowings and repayments under the collateralized loans are reflected as financing cash flows within our Consolidated Statements of Cash Flows. Iron Mountain Information Management, LLC retains the responsibility of servicing the accounts receivable balances pledged as collateral for the Accounts Receivable Securitization Program and IMI provides a performance guaranty. The maximum availability allowed is limited by eligible accounts receivable, as defined under the terms of the Accounts Receivable Securitization Program. The Accounts Receivable Securitization Program is secured by a substantial majority of our net receivables in the United States.
The maximum amount permitted to be borrowed under the Accounts Receivable Securitization Program is $400,000 and the maturity date is July 1, 2027, at which point all obligations become due. As of December 31, 2025 and 2024, the amount outstanding under the Accounts Receivable Securitization Program was $400,000 and $400,000, respectively. The interest rate in effect under the Accounts Receivable Securitization Program was 4.7% and 5.6% as of December 31, 2025 and 2024, respectively. We have the option to increase the borrowing capacity by $75,000. Commitment fees at a rate of 35 basis points are charged on amounts made available but not borrowed under the Accounts Receivable Securitization Program. | MAXIMUM AMOUNT $400,000 | ||||||||||

G. CASH POOLING
Certain of our subsidiaries participate in cash pooling arrangements (the "Cash Pools") to help manage global liquidity requirements. We utilize the following Cash Pools: (i) two Cash Pools with ING Bank NV (doing business as Bank Mendes Gans), one of which we use to manage global liquidity requirements for our qualified REIT subsidiaries ("QRSs") and the other for our taxable REIT subsidiaries ("TRSs"), (ii) two Cash Pools with JP Morgan Chase Bank, N.A. ("JPM"), one of which we use to manage liquidity requirements for our QRSs in the Asia Pacific region and the other for our TRSs in the Asia Pacific region and (iii) two Cash Pools with JPM, one of which we use to manage liquidity requirements for our QRSs in the Europe, Middle East, and Africa regions and the other for our TRSs in the Europe, Middle East, and Africa regions.
Under each of the Cash Pools, cash deposited by participating subsidiaries with certain financial institutions is pledged as security against the debit balances of other participating subsidiaries with legal rights of offset provided to the financial institutions. Therefore, such amounts are presented in our Consolidated Balance Sheets on a net basis. Each subsidiary receives interest on the cash balances held on deposit or pays interest on its debit balances based on an applicable rate as defined in the Cash Pools.
The net cash position balances as of December 31, 2025 and 2024 are reflected as Cash and cash equivalents in our Consolidated Balance Sheets.
H. LETTERS OF CREDIT
As of December 31, 2025, we had outstanding letters of credit totaling $80,751, of which $12,398 reduce our borrowing capacity under the Revolving Credit Facility (as described above). The letters of credit expire at various dates between February 2026 and May 2027.
I. DEBT COVENANTS
The Credit Agreement, our bond indentures and other agreements governing our indebtedness contain certain restrictive financial and operating covenants, including covenants that restrict our ability to complete acquisitions, pay cash dividends, incur indebtedness, make investments, sell assets and take other specified corporate actions. The covenants do not contain a rating trigger. Therefore, a change in our debt rating would not trigger a default under the Credit Agreement, our bond indentures or other agreements governing our indebtedness. The Credit Agreement requires that we satisfy a net total lease adjusted leverage ratio and a fixed charge coverage ratio on a quarterly basis, and our bond indentures require that, among other things, we satisfy a leverage ratio (not lease adjusted) or a fixed charge coverage ratio (not lease adjusted), as a condition to taking actions such as paying dividends and incurring indebtedness.
The Credit Agreement uses EBITDAR-based calculations and the bond indentures use earnings before income, taxes, depreciation and amortization ("EBITDA") based calculations as the primary measures of financial performance for purposes of calculating leverage and fixed charge coverage ratios. The EBITDAR- and EBITDA-based leverage calculations include our consolidated subsidiaries, other than those we have designated as "Unrestricted Subsidiaries" as defined in the Credit Agreement and bond indentures. Generally, the Credit Agreement and the bond indentures use a trailing four fiscal quarter basis for purposes of the relevant calculations and require certain adjustments and exclusions for purposes of those calculations, which make the calculation of financial performance under the Credit Agreement and bond indentures not directly comparable to Adjusted EBITDA as presented herein. We are in compliance with our leverage and fixed charge coverage ratios under the Credit Agreement, our bond indentures and other agreements governing our indebtedness as of December 31, 2025. Noncompliance with these leverage and fixed charge coverage ratios would have a material adverse effect on our financial condition and liquidity.

About Debt Disclosures
Debt disclosures detail a company's borrowing structure — the types of instruments, interest rates, maturity schedule, and covenant restrictions that define its financial obligations and flexibility. This section is essential for assessing refinancing risk, interest rate exposure, and the margin of safety against financial distress.
Key signals: the maturity schedule reveals concentration risk — large maturities within 1-2 years during tight credit markets can force dilutive refinancing or asset sales. Compare the fair value of debt against carrying amount to gauge whether the market views the company's credit risk differently than the balance sheet suggests. Watch covenant compliance disclosures for tightening cushions, especially leverage and interest coverage ratios. Variable-rate debt exposure quantifies sensitivity to interest rate changes. Secured versus unsecured mix affects recovery rates and future borrowing capacity. Compare net debt-to-EBITDA against industry peers and covenant limits to assess financial health.
