The level 3 valuations of the deferred purchase obligations were determined utilizing a discounted cash flow model and take into account our forecasted projections as they relate to the underlying performance of the business. The discounted cash flow model incorporates assumptions as to expected results over the achievement period, including adjustments for volatility and timing, as well as discount rates that account for the risk of the arrangement and overall market risks. Any material change to these assumptions may result in a significantly higher or lower fair value of the deferred purchase obligations.
There were no material items that were measured at fair value on a non-recurring basis as of June 30, 2026 and December 31, 2025 other than those disclosed in Note 2.p. to Notes to Consolidated Financial Statements included in our Annual Report.

4. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
Derivative instruments we are party to include: (i) interest rate swap agreements (which are designated as cash flow hedges) and (ii) cross-currency swap agreements (which are designated as net investment hedges).
INTEREST RATE SWAP AGREEMENTS DESIGNATED AS CASH FLOW HEDGES
We utilize interest rate swap agreements designated as cash flow hedges to limit our exposure to changes in interest rates on a portion of our floating rate indebtedness. Certain of our interest rate swap agreements have notional amounts that will increase with the underlying hedged transaction. Under our interest rate swap agreements, we receive variable rate interest payments associated with the notional amount of each interest rate swap, based upon the one-month Secured Overnight Financing Rate ("SOFR"), in exchange for the payment of fixed interest rates as specified in the interest rate swap agreements. Our interest rate swap agreements are marked to market at the end of each reporting period, representing the fair values of the interest rate swap agreements, and any changes in fair value are recognized as a component of Accumulated other comprehensive items, net. Unrealized gains are recognized as assets, while unrealized losses are recognized as liabilities.
As of June 30, 2026 and December 31, 2025, we have approximately $1,032,000 and $1,349,000, respectively, in notional value outstanding on our interest rate swap agreements. As of June 30, 2026, our interest rate swap agreements have maturity dates ranging from August 2026 through June 2029.
CROSS-CURRENCY SWAP AGREEMENTS DESIGNATED AS NET INVESTMENT HEDGES
We utilize cross-currency swaps to hedge the variability of exchange rate impacts between the United States dollar and certain of our foreign functional currencies, including the Euro and the Canadian dollar. As of June 30, 2026, our cross-currency swap agreements have maturity dates ranging from November 2026 through February 2029.
The notional values of our cross-currency swaps, by hedged currency, as of June 30, 2026 and December 31, 2025, are as follows:
JUNE 30, 2026DECEMBER 31, 2025
Euro$504,559 $509,187 
Canadian dollar350,000 350,000 

$854,559 $859,187 
We have designated these cross-currency swap agreements as hedges of net investments in our Euro and Canadian dollar denominated subsidiaries and they require an exchange of the notional amounts at maturity. These cross-currency swap agreements are marked to market at the end of each reporting period, representing the fair values of the cross-currency swap agreements, and any changes in fair value are recognized as a component of Accumulated other comprehensive items, net. Unrealized gains are recognized as assets, while unrealized losses are recognized as liabilities. The excluded component of our cross-currency swap agreements is recorded in Accumulated other comprehensive items, net and amortized to interest expense on a straight-line basis.

DATA CENTER DEBT AGREEMENTS
On January 9, 2026, Iron Mountain Data Centers Virginia 3, LLC and Iron Mountain Data Centers Virginia 3 Intermediate II, LLC, both wholly-owned subsidiaries of IMI, entered into a mortgage loan agreement and a mezzanine loan agreement with a total original principal balance of $433,000 (the "Virginia 3 Term Loans due 2031"). The Virginia 3 Term Loans due 2031 are secured by the property of Iron Mountain Data Centers Virginia 3, LLC and are scheduled to mature on January 9, 2031, at which point all obligations will become due. The Virginia 3 Term Loans due 2031 bear interest at a weighted average rate of 6.3%. Total net proceeds from the Virginia 3 Term Loans due 2031 were used to repay the Virginia 3 Term Loans due 2026 (defined as the Virginia 3 Term Loans in Note 6 to Notes to Consolidated Financial Statements included in our Annual Report) and a portion of the outstanding borrowings under the Revolving Credit Facility.
On June 9, 2026, Iron Mountain Data Centers Virginia 9, LLC, an indirect subsidiary of IMI, entered into a credit agreement that includes a term loan facility (the "Virginia 9 Term Loans") and a letter of credit facility (collectively, the "Virginia 9 Credit Agreement"), under which we have the option to borrow, in the form of term loans, an aggregate outstanding amount not to exceed $298,000. The Virginia 9 Term Loans bear interest at SOFR plus 3.00%. The Virginia 9 Credit Agreement requires the payment of a commitment fee on any unused commitments at a rate of 0.90%. The Virginia 9 Credit Agreement is secured by the equity interests and assets of Iron Mountain Data Centers Virginia 9, LLC and is scheduled to mature on June 9, 2029, at which point all obligations will become due. We have two one-year options that allow us to extend the maturity date, subject to the conditions specified in the Virginia 9 Credit Agreement. As of June 30, 2026, we had $29,595 outstanding on the Virginia 9 Term Loans and the interest rate in effect under the Virginia 9 Credit Agreement was 6.9%.
ACCOUNTS RECEIVABLE SECURITIZATION PROGRAM
On May 28, 2026, we amended the Accounts Receivable Securitization Program (as defined in Note 6 to Notes to Consolidated Financial Statements included in our Annual Report) to (i) include the sale of accounts receivable from certain of our wholly-owned Canadian entities, (ii) increase the maximum borrowing capacity from $400,000 to $450,000 and (iii) extend the maturity date from July 1, 2027 to July 1, 2029, at which point all obligations become due.

JUNE 2026 OFFERING
On June 26, 2026, IMI completed a private offering of:
SERIES OF NOTESAGGREGATE PRINCIPAL AMOUNTMATURITY DATEINTEREST PAYMENT DUE
PAR CALL DATE(1)
61/4% Notes due 2035
$1,500,000 January 15, 2035January 15 and July 15July 15, 2031
(1)We may redeem the 61/4% Notes due 2035 at any time, at our option, in whole or in part. Prior to the par call date, we may redeem the 61/4% Notes due 2035 at the redemption price or make-whole premium specified in the indenture governing the 61/4% Notes due 2035, together with accrued and unpaid interest to, but excluding, the redemption date. On or after the par call date, we may redeem the 61/4% Notes due 2035 at a price equal to 100% of the principal amount being redeemed, together with accrued and unpaid interest to, but excluding, the redemption date.
The 61/4% Notes due 2035 were issued at par and have a contractual interest rate of 6.25%. The total net proceeds from the issuance, after deducting the initial purchasers' commissions and third-party fees, of approximately $1,481,800 were used to repay a portion of the outstanding borrowings under the Revolving Credit Facility and for general corporate purposes. As of June 30, 2026, we had $1,500,000 outstanding on the 61/4% Notes due 2035.
LETTERS OF CREDIT
As of June 30, 2026, we have outstanding letters of credit totaling $51,395, of which $12,426 reduces our borrowing capacity under the Revolving Credit Facility. The letters of credit expire at various dates between October 2026 and July 2027.
DEBT COVENANTS
The Credit Agreement, certain of 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 certain of 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 earnings before interest, taxes, depreciation and amortization and rent expense ("EBITDAR")-based calculations and the bond indentures use earnings before interest, 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 June 30, 2026. Noncompliance with these leverage and fixed charge coverage ratios would have a material adverse effect on our financial condition and liquidity.
6. COMMITMENTS AND CONTINGENCIES
We are involved in litigation from time to time in the ordinary course of business, including litigation arising from damage to customer assets in our facilities caused by fires and other natural disasters. While the outcome of litigation is inherently uncertain, we do not believe any current litigation will have a material adverse effect on our consolidated financial condition, results of operations or cash flows.

10. RESTRUCTURING AND OTHER TRANSFORMATION
PROJECT MATTERHORN
In 2025, we completed our investments in Project Matterhorn, a global program designed to accelerate the growth of our business ("Project Matterhorn"), which we announced in September 2022. The implementation of Project Matterhorn resulted in Restructuring and other transformation costs which were comprised of: (1) restructuring costs, which included (i) site consolidation and other related exit costs, (ii) employee severance costs and (iii) certain professional fees associated with these activities, and (2) other transformation costs, which included professional fees such as project management costs and costs for third party consultants who assisted in the enablement of our growth initiatives.
As Project Matterhorn was completed as of December 31, 2025, there were no Restructuring and other transformation costs for the three and six months ended June 30, 2026. Total Restructuring and other transformation costs for the three and six months ended June 30, 2025 were $50,340 and $105,086, respectively, and consisted of (i) restructuring costs of $18,246 and $40,102, respectively, and (ii) other transformation costs of $32,094 and $64,984, respectively.

FORWARD-LOOKING STATEMENTS
We have made statements in this Quarterly Report that constitute "forward-looking statements" as that term is defined in the Private Securities Litigation Reform Act of 1995 and other securities laws. These forward-looking statements concern our current expectations regarding our future results from operations, economic performance, financial condition, goals, strategies, investment objectives, plans and achievements.

OVERVIEW
The following discussions set forth, for the periods indicated, management's discussion and analysis of financial condition and results of operations. Significant trends and changes are discussed for the three and six months ended June 30, 2026 within each section. Trends and changes that are consistent for both the three and six month periods are not repeated and are discussed on a year to date basis only.
GENERAL
RESULTS OF OPERATIONS—KEY TRENDS
•Our organic storage rental revenue growth is primarily driven by revenue management in our Global RIM Business segment, where we expect volume to be relatively stable in the near term, as well as by growth in our Global Data Center Business segment, primarily driven by lease commencements.
•Our organic service revenue growth is primarily driven by new and existing digital offerings, traditional records management services and services in our asset lifecycle management ("ALM") business, all of which we expect to grow in the near term and benefit our organic service revenue growth in 2026.
•We expect continued total revenue and Adjusted earnings before interest, taxes, depreciation and amortization ("EBITDA") growth in 2026 as a result of our focus on new product and service offerings, cross-selling opportunities, innovation, customer solutions and market expansion in line with our growth strategies.
Cost of sales (excluding depreciation and amortization) and Selling, general and administrative expenses for the six months ended June 30, 2026 consists of the following:

NON-GAAP MEASURES
ADJUSTED EBITDA
We define Adjusted EBITDA as net income (loss) before interest expense, net, provision (benefit) for income taxes, depreciation and amortization (inclusive of our share of Adjusted EBITDA from our unconsolidated joint ventures), and excluding certain items we do not believe to be indicative of our core operating results, specifically:
EXCLUDED
•Acquisition and Integration Costs (as defined below)
•Restructuring and other transformation
•Loss (gain) on disposal/write-down of property, plant and equipment, net (including real estate)
•Other expense (income), net
•Stock-based compensation expense
•Intangible impairments
Adjusted EBITDA Margin is calculated by dividing Adjusted EBITDA by total revenues. We also show Adjusted EBITDA and Adjusted EBITDA Margin for each of our reportable segments under "Results of Operations – Segment Analysis" below.
p27_callout_ProjectedAdjustedEBITDA.jpg
Adjusted EBITDA excludes both interest expense, net and the provision (benefit) for income taxes. These expenses are associated with our capitalization and tax structures, which we do not consider when evaluating the operating profitability of our core operations. Adjusted EBITDA does not include depreciation and amortization expenses, in order to eliminate the impact of capital investments, which we evaluate by comparing capital expenditures to incremental revenue generated and as a percentage of total revenues. Adjusted EBITDA and Adjusted EBITDA Margin should be considered in addition to, but not as a substitute for, other measures of financial performance reported in accordance with accounting principles generally accepted in the United States of America ("GAAP"), such as operating income (loss), net income (loss) or cash flows from operating activities.

ADJUSTED EPS
We define Adjusted EPS as reported earnings per share fully diluted from net income (loss) attributable to Iron Mountain Incorporated (inclusive of our share of adjusted losses (gains) from our unconsolidated joint ventures) and excluding certain items, specifically:
EXCLUDED
•Acquisition and Integration Costs
•Restructuring and other transformation
•Loss (gain) on disposal/write-down of property, plant and equipment, net (including real estate)
•Other expense (income), net
•Stock-based compensation expense
•Non-cash amortization related to derivative instruments
•Tax impact of reconciling items and discrete tax items
•Amortization related to the write-off of certain customer relationship intangible assets
We do not believe these excluded items to be indicative of our ongoing operating results, and they are not considered when we are forecasting our future results. We believe Adjusted EPS is of value to our current and potential investors when comparing our results from past, present and future periods.

Our structural tax rate for purposes of the calculation of Adjusted EPS for the three and six months ended June 30, 2026 and 2025 was 16.1% and 16.7%, respectively. The Tax impact of reconciling items and discrete tax items is calculated using the current quarter's estimate of the annual structural tax rate. This may result in the current period adjustment plus prior period reported quarterly adjustments not summing to the full year adjustment.

FFO (NAREIT) AND FFO (NORMALIZED)
Funds from operations ("FFO") is defined by the National Association of Real Estate Investment Trusts as net income (loss) excluding depreciation on real estate assets, losses and gains on sale of real estate, net of tax, and amortization of data center leased-based intangibles ("FFO (Nareit)"). We calculate our FFO measures, including FFO (Nareit), adjusting for our share of reconciling items from our unconsolidated joint ventures. FFO (Nareit) does not give effect to real estate depreciation because these amounts are computed, under GAAP, to allocate the cost of a property over its useful life. Because values for well-maintained real estate assets have historically increased or decreased based upon prevailing market conditions, we believe that FFO (Nareit) provides investors with a clearer view of our operating performance. Our most directly comparable GAAP measure to FFO (Nareit) is net income (loss).
We modify FFO (Nareit), as is common among REITs seeking to provide financial measures that most meaningfully reflect their particular business ("FFO (Normalized)"). Our definition of FFO (Normalized) excludes certain items included in FFO (Nareit) that we believe are not indicative of our core operating results, specifically:
EXCLUDED
•Acquisition and Integration Costs
•Restructuring and other transformation
•Loss (gain) on disposal/write-down of property, plant and equipment, net (excluding real estate)
•Other expense (income), net
•Stock-based compensation expense
•Non-cash amortization related to derivative instruments
•Real estate financing lease depreciation
•Tax impact of reconciling items and discrete tax items
•Intangible impairments

CRITICAL ACCOUNTING ESTIMATES
Our discussion and analysis of our financial condition and results of operations are based upon our Condensed Consolidated Financial Statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the financial statements and for the period then ended. On an ongoing basis, we evaluate the estimates used. We base our estimates on historical experience, actuarial estimates, current conditions and various other assumptions that we believe to be reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of assets and liabilities and are not readily apparent from other sources. Actual results may differ from these estimates. Our critical accounting estimates include the following, which are listed in no particular order:
•Revenue Recognition
•Accounting for Acquisitions
•Impairment of Tangible and Intangible Assets
•Income Taxes
Further detail regarding our critical accounting estimates can be found in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report, and the Consolidated Financial Statements and the Notes included therein. We have determined that no material changes concerning our critical accounting estimates have occurred since December 31, 2025.

INTEREST EXPENSE, NET
Interest expense, net increased $47.5 million to $447.3 million in the six months ended June 30, 2026 from $399.8 million in the prior year period. The increase is primarily due to higher average debt outstanding during the six months ended June 30, 2026 compared to the prior year period. Our weighted average interest rate, inclusive of the fees associated with our outstanding letters of credit, was 5.6% and 5.7% as of June 30, 2026 and 2025, respectively. See Note 5 to Notes to Condensed Consolidated Financial Statements included in this Quarterly Report for additional information regarding our indebtedness.

PROVISION (BENEFIT) FOR INCOME TAXES
We provide for income taxes during interim periods based on our estimate of the effective tax rate for the year. Our effective tax rates for the three and six months ended June 30, 2026 and 2025 are as follows:
THREE MONTHS ENDED JUNE 30,SIX MONTHS ENDED JUNE 30,
2026202520262025
Effective Tax Rate12.2 %60.3 %14.1 %773.6 %
The primary reconciling items between the federal statutory tax rate of 21.0% and our overall effective tax rate for the three and six months ended June 30, 2026 were the (i) benefits derived from the dividends paid deduction, (ii) non-taxable income we recorded in Other expense (income), net during the period, as well as the differences in the tax rates to which our foreign earnings are subject, partially offset by (iii) disallowed interest expenses of certain entities.
Effective on January 1, 2026, the One Big Beautiful Bill Act increased the maximum allowable value of a REIT’s total assets held in one or more taxable REIT subsidiaries at the end of any quarter from 20% to 25%.
Beginning in 2024, we became subject to the Organization for Economic Cooperation and Development (the “OECD”) Global Anti-Base Erosion Model Rules (“Pillar Two”). Pillar Two may impose additional taxes (“Top-Up Taxes”) if the effective tax rate (as defined by the OECD) in a jurisdiction is below 15%. Pillar Two does not apply to “Excluded Entities” and certain subsidiaries of Excluded Entities. We continue to believe that we qualify as an Excluded Entity as a “Real Estate Investment Vehicle.” In the event certain subsidiaries do not qualify as Excluded Entities, available safe harbor rules could apply that would exempt the entities from any Top-Up Taxes. Substantially all of our non-excluded, non-U.S. jurisdictions qualify for one or more of the safe harbor rules.
On January 5, 2026, the OECD announced a comprehensive Side-by-Side safe harbor package (the “SbS Safe Harbor”) that, if enacted, would exempt U.S.-parented multinational companies from certain Top-Up Taxes under Pillar Two beginning January 1, 2026. While the SbS Safe Harbor is not yet enacted in any foreign jurisdiction where we operate, we expect that the SbS Safe Harbor may be adopted prior to the year ended December 31, 2026.
We do not expect the Top-Up Taxes of the remaining non-U.S. jurisdictions that may not qualify for the safe harbor rules, or the Top-Up Taxes from our U.S. income that may be subject to Pillar Two, to have a material impact on our consolidated financial statements.

DATA CENTER DEBT AGREEMENTS
On January 9, 2026, Iron Mountain Data Centers Virginia 3, LLC and Iron Mountain Data Centers Virginia 3 Intermediate II, LLC, both wholly-owned subsidiaries of Iron Mountain Incorporated ("IMI"), entered into a mortgage loan agreement and a mezzanine loan agreement with a total original principal balance of $433.0 million (the "Virginia 3 Term Loans due 2031"). The Virginia 3 Term Loans due 2031 are secured by the property of Iron Mountain Data Centers Virginia 3, LLC and are scheduled to mature on January 9, 2031, at which point all obligations will become due. The Virginia 3 Term Loans due 2031 bear interest at a weighted average rate of 6.3%. Total net proceeds from the Virginia 3 Term Loans due 2031 were used to repay the Virginia 3 Term Loans due 2026 (defined as the Virginia 3 Term Loans in Note 6 to Notes to Consolidated Financial Statements included in our Annual Report) and a portion of the outstanding borrowings under the Revolving Credit Facility.
On June 9, 2026, Iron Mountain Data Centers Virginia 9, LLC, an indirect subsidiary of IMI, entered into a credit agreement that includes a term loan facility (the "Virginia 9 Term Loans") and a letter of credit facility (collectively, the "Virginia 9 Credit Agreement"), under which we have the option to borrow, in the form of term loans, an aggregate outstanding amount not to exceed $298.0 million. The Virginia 9 Term Loans bear interest at SOFR plus 3.00%. The Virginia 9 Credit Agreement requires the payment of a commitment fee on any unused commitments at a rate of 0.90%. The Virginia 9 Credit Agreement is secured by the equity interests and assets of Iron Mountain Data Centers Virginia 9, LLC and is scheduled to mature on June 9, 2029, at which point all obligations will become due. We have two one-year options that allow us to extend the maturity date, subject to the conditions specified in the Virginia 9 Credit Agreement. As of June 30, 2026, we had $29.6 million outstanding on the Virginia 9 Term Loans and the interest rate in effect under the Virginia 9 Credit Agreement was 6.9%.
ACCOUNTS RECEIVABLE SECURITIZATION PROGRAM
On May 28, 2026, we amended the Accounts Receivable Securitization Program (as defined in Note 6 to Notes to Consolidated Financial Statements included in our Annual Report) to (i) include the sale of accounts receivable from certain of our wholly-owned Canadian entities, (ii) increase the maximum borrowing capacity from $400.0 million to $450.0 million and (iii) extend the maturity date from July 1, 2027 to July 1, 2029, at which point all obligations become due.

The 61/4% Notes due 2035 were issued at par and have a contractual interest rate of 6.25%. The total net proceeds from the issuance, after deducting the initial purchasers' commissions and third-party fees, of approximately $1,481.8 million, were used to repay a portion of the outstanding borrowings under the Revolving Credit Facility and to pay related fees and expenses, and for general corporate purposes. As of June 30, 2026, we had $1,500.0 million outstanding on the 61/4% Notes due 2035.
DEBT COVENANTS
The Credit Agreement, certain of 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 certain of 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.

Table of Contents
Part I. Financial Information
The Credit Agreement uses earnings before interest, taxes, depreciation and amortization and rent expense ("EBITDAR")-based calculations and the bond indentures use 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. These adjustments can be significant. For example, the calculation of financial performance under the Credit Agreement and certain of our bond indentures includes (subject to specified exceptions and caps) adjustments for non-cash charges and for expected benefits associated with (i) completed acquisitions, (ii) certain executed lease agreements associated with our data center business that have yet to commence and (iii) restructuring and other strategic initiatives. The calculation of financial performance under our other bond indentures includes, for example, adjustments for non-cash charges and for expected benefits associated with (i) completed acquisitions and (ii) events that are extraordinary, unusual or non-recurring.
Our leverage and fixed charge coverage ratios under the Credit Agreement as of June 30, 2026 are as follows:
JUNE 30, 2026MAXIMUM/MINIMUM ALLOWABLE
Net total lease adjusted leverage ratio4.8 Maximum allowable of 7.0
Fixed charge coverage ratio2.5 Minimum allowable of 1.5
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 June 30, 2026. Noncompliance with these leverage and fixed charge coverage ratios would have a material adverse effect on our financial condition and liquidity.
Our ability to pay interest on or to refinance our indebtedness depends on our future performance, working capital levels and capital structure, which are subject to general economic, financial, competitive, legislative, regulatory and other factors which may be beyond our control. There can be no assurance that we will generate sufficient cash flow from our operations or that future financings will be available on acceptable terms or in amounts sufficient to enable us to service or refinance our indebtedness or to make necessary capital expenditures.
DERIVATIVE INSTRUMENTS
INTEREST RATE SWAP AGREEMENTS
We utilize interest rate swap agreements designated as cash flow hedges to limit our exposure to changes in interest rates on a portion of our floating rate indebtedness. Certain of our interest rate swap agreements have notional amounts that will increase with the underlying hedged transaction. Under our interest rate swap agreements, we receive variable rate interest payments associated with the notional amount of each interest rate swap, based upon the one-month Secured Overnight Financing Rate ("SOFR"), in exchange for the payment of fixed interest rates as specified in the interest rate swap agreements. Our interest rate swap agreements are marked to market at the end of each reporting period, representing the fair values of the interest rate swap agreements, and any changes in fair value are recognized as a component of Accumulated other comprehensive items, net. Unrealized gains are recognized as assets, while unrealized losses are recognized as liabilities.
As of June 30, 2026 and December 31, 2025, we have approximately $1,032.0 million and $1,349.0 million, respectively, in notional value outstanding on our interest rate swap agreements. As of June 30, 2026, our interest rate swap agreements have maturity dates ranging from August 2026 through June 2029.

CROSS-CURRENCY SWAP AGREEMENTS
We utilize cross-currency swaps to hedge the variability of exchange rate impacts between the United States dollar and certain of our foreign functional currencies, including the Euro and the Canadian dollar. As of June 30, 2026, our cross-currency swap agreements have maturity dates ranging from November 2026 through February 2029.
The notional values of our cross-currency swaps, by hedged currency, as of June 30, 2026 and December 31, 2025, are as follows (in thousands):

Euro$504,559 $509,187 
Canadian dollar350,000 350,000 

$854,559 $859,187 
We have designated these cross-currency swap agreements as hedges of net investments in our Euro and Canadian dollar denominated subsidiaries and they require an exchange of the notional amounts at maturity. These cross-currency swap agreements are marked to market at the end of each reporting period, representing the fair values of the cross-currency swap agreements, and any changes in fair value are recognized as a component of Accumulated other comprehensive items, net. Unrealized gains are recognized as assets, while unrealized losses are recognized as liabilities. The excluded component of our cross-currency swap agreements is recorded in Accumulated other comprehensive items, net and amortized to interest expense on a straight-line basis.

DISCLOSURE CONTROLS AND PROCEDURES
The term "disclosure controls and procedures" is defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). These rules refer to the controls and other procedures of a company that are designed to ensure that information is recorded, processed, accumulated, summarized, communicated and reported to management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding what is required to be disclosed by a company in the reports that it files under the Exchange Act.
As of June 30, 2026 (the "Evaluation Date"), we carried out an evaluation, under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of our disclosure controls and procedures. Based upon that evaluation, our chief executive officer and chief financial officer concluded that, as of the Evaluation Date, our disclosure controls and procedures are effective.
CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING
Our management, with the participation of our principal executive officer and principal financial officer, is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Our internal control system is designed to provide reasonable assurance to our management and board of directors regarding the preparation and fair presentation of published financial statements.
There were no changes in our internal control over financial reporting that occurred during the quarter ended June 30, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
