Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business	NATURE OF BUSINESS The accompanying financial statements represent the consolidated accounts of Iron Mountain Incorporated, a Delaware corporation ("IMI"), and its subsidiaries ("we" or "us"). IMI was founded in an underground facility near Hudson, New York in 1951 where it stored business records. Today, we are a global leader in information management services, and we are trusted by more than 240,000 customers in 61 countries, including approximately 95% of the Fortune 1000, to help unlock value and intelligence from their assets through services that transcend the physical and digital worlds. Our broad range of solutions address their information management, digital transformation, information security, data center and asset lifecycle management (“ALM”) needs. Our longstanding commitment to safety, security, sustainability and innovation in support of our customers underpins everything we do. We currently serve customers across an array of market verticals — commercial, legal, financial, healthcare, technology, insurance, life sciences, energy, business services, entertainment and government organizations. We have been organized and have operated as a real estate investment trust for United States federal income tax purposes ("REIT") beginning with our taxable year ended December 31, 2014.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES A. PRINCIPLES OF CONSOLIDATION The accompanying financial statements reflect our financial position, results of operations, comprehensive income (loss), (deficit) equity and cash flows on a consolidated basis. The accompanying financial statements include the results of those entities over which we have a controlling financial interest or of which we are deemed to be the primary beneficiary. All intercompany transactions and account balances have been eliminated. B. USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the 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. C. CHANGES IN PRESENTATION Certain items previously reported under specific captions within the statement of cash flows and Note 10 have been reclassified to conform to the current year presentation. D. FOREIGN CURRENCY Local currencies are the functional currencies for our operations outside the United States, with the exception of certain foreign holding companies, whose functional currency is the United States dollar. In those instances where the local currency is the functional currency, assets and liabilities are translated at period-end exchange rates, and revenues and expenses are translated at average exchange rates for the applicable period. See Note 2.r. E. CASH AND CASH EQUIVALENTS Cash and cash equivalents include cash on hand and cash invested in highly liquid short-term securities, which have remaining maturities at the date of purchase of less than 90 days. Cash and cash equivalents are carried at cost, which approximates fair value. F. ALLOWANCE FOR DOUBTFUL ACCOUNTS AND CREDIT MEMO RESERVES We maintain an allowance for doubtful accounts and a credit memo reserve for estimated losses resulting from the potential inability of our customers to make required payments and potential disputes regarding billing and service issues. We evaluate and monitor the collectability of accounts receivable based on a combination of factors, including historical loss experience, assessments of trends in our aged receivables and credit memo activity, the location of our businesses, the composition of our customer base, our product and service lines, potential future macroeconomic factors, including natural disasters, and reasonable and supportable forecasts for expected future collectability of our outstanding receivables. Continued adjustments will be made, as it becomes evident, should there be any material change to reasonable and supportable forecasts that may impact our likelihood of collection. Our highly diverse global customer base, with no single customer accounting for more than approximately 1% of revenue during the years ended December 31, 2024, 2023 and 2022, limits our exposure to concentration of credit risk. Additionally, we write off uncollectible balances as circumstances warrant, generally no later than one year past due. The rollforward of the allowance for doubtful accounts and credit memo reserves is as follows: YEAR ENDED DECEMBER 31, BALANCE AT BEGINNING OF THE YEAR CREDIT MEMOS CHARGED TO REVENUE ALLOWANCE FOR BAD DEBTS CHARGED TO EXPENSE DEDUCTIONS AND OTHER (1) BALANCE AT 2024 $ 74,762 $ 104,130 $ 45,123 $ (137,303) $ 86,712 2023 54,143 92,881 32,692 (104,954) 74,762 2022 62,009 62,891 13,666 (84,423) 54,143 (1) Primarily consists of the issuance of credit memos, the write-off of accounts receivable and the impact associated with currency translation adjustments. G. CONCENTRATIONS OF CREDIT RISK H. PREPAID EXPENSES AND ACCRUED EXPENSES Prepaid expenses totaled $131,615 and $126,904 as of December 31, 2024 and 2023, respectively. There were no other items greater than 5% of total current assets included within Prepaid expenses and other as of December 31, 2024 and 2023. Accrued expenses and other current liabilities with items greater than 5% of total current liabilities are shown separately and consist of the following: DECEMBER 31, DESCRIPTION 2024 2023 Current portion of operating lease liabilities $ 315,400 $ 291,795 Accrued compensation and benefits 244,499 242,992 Dividends 222,649 202,392 Interest 164,336 175,218 Deferred purchase obligations, purchase price holdbacks and other 137,207 171,273 Other 282,477 166,589 Accrued expenses and other current liabilities $ 1,366,568 $ 1,250,259 I. PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are stated at cost and depreciated using the straight-line method with the following useful lives (in years): DESCRIPTION RANGE Buildings, building improvements and data center infrastructure 5 to 40 Leasehold improvements 5 to 20 or life of the lease (whichever is shorter) Racking structures 1 to 20 or life of the lease (whichever is shorter) Warehouse equipment/vehicles 1 to 10 Furniture and fixtures 1 to 10 Computer hardware and software 2 to 7 Property, plant and equipment (including financing leases in the respective categories), at cost, consist of the following: DECEMBER 31, DESCRIPTION 2024 2023 Land $ 670,529 $ 536,780 Buildings, building improvements and data center infrastructure 4,768,835 3,819,241 Leasehold improvements 1,536,919 1,166,810 Racking structures 1,978,923 2,054,046 Warehouse equipment/vehicles 644,340 526,965 Furniture and fixtures 45,918 46,094 Computer hardware and software 751,627 601,273 Construction in progress 1,588,906 1,622,780 Property, plant and equipment $ 11,985,997 $ 10,373,989 Minor maintenance costs are expensed as incurred. Major improvements which (i) extend the life, (ii) increase the capacity or functionality or (iii) improve the safety or the efficiency of property owned are capitalized and depreciated. Major improvements to leased buildings are capitalized as leasehold improvements and depreciated. CAPITALIZED INTEREST We capitalize interest expense during the active construction period of major capital projects. Capitalized interest is added to the cost of the underlying assets and is amortized over the useful lives of the assets. During the years ended December 31, 2024, 2023 and 2022, capitalized interest is as follows: YEAR ENDED DECEMBER 31, 2024 2023 2022 Capitalized interest $ 63,333 $ 44,845 $ 14,078 INTERNAL USE SOFTWARE We develop various software applications for internal use. Computer software costs associated with internal use software are expensed as incurred until certain capitalization criteria are met. Third party consulting costs, as well as payroll and related costs for employees directly associated with, and devoting time to, the development of internal use computer software projects (to the extent time is spent directly on the project) are capitalized. Capitalization of costs, including costs incurred for upgrades and enhancements that provide additional functionality to our existing software, generally begins during the application development stage of the project, which occurs after it is probable that the project will be completed and used to perform the function intended. Capitalization ends when the asset is ready for its intended use. Capitalized internal use software costs are depreciated on a straight-line basis over the expected useful life of the software, commencing when the software is ready for its intended use. Computer software costs that are capitalized are periodically evaluated for impairment. During the years ended December 31, 2024, 2023 and 2022, capitalized costs associated with the development of internal use computer software projects are as follows: YEAR ENDED DECEMBER 31, 2024 2023 2022 Capitalized costs associated with the development of internal use computer software projects $ 69,055 $ 64,488 $ 44,152 ASSET RETIREMENT OBLIGATIONS Entities are required to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. Asset retirement obligations represent the costs to replace or remove tangible long-lived assets required by law, regulatory rule or contractual agreement. Our asset retirement obligations are primarily the result of requirements under our facility lease agreements which generally have "return to original condition" clauses which would require us to remove or restore items such as shred pits, vaults, demising walls and office build-outs, among others. The significant assumptions used in estimating our aggregate asset retirement obligations are the timing of removals, the probability of a requirement to perform, estimated cost and associated expected inflation rates that are consistent with historical rates and credit-adjusted risk-free rates that approximate our incremental borrowing rate. Our asset retirement obligations at December 31, 2024 and 2023 were $43,844 and $36,602, respectively, and are included in Other Long-term Liabilities in our Consolidated Balance Sheets. J. LEASES We lease facilities for certain warehouses, data centers and office spaces. We also have land leases, including those on which certain facilities are located. The majority of our leased facilities are classified as operating leases that, on average, have initial lease terms of five one one We account for all leases, both operating and financing, in accordance with Accounting Standards Codification ("ASC") Topic 842, Leases ("ASC 842"). Our accounting policy provides that leases with an initial term of 12 months or less will not be included within the lease right-of-use assets and lease liabilities recognized on our Consolidated Balance Sheets. We recognize the lease payments for those leases with an initial term of 12 months or less in our Consolidated Statements of Operations on a straight-line basis over the lease term. The lease right-of-use assets and related lease liabilities are classified as either operating or financing. Lease right-of-use assets are calculated as the net present value of future payments plus any capitalized initial direct costs less any tenant improvements or lease incentives. Lease liabilities are calculated as the net present value of future payments. In calculating the present value of the lease payments, we utilize the rate stated in the lease (in the limited circumstances when such rate is explicitly stated) or, if no rate is explicitly stated, we utilize a rate that reflects our securitized incremental borrowing rate by geography for the lease term. We account for nonlease components (which include common area maintenance, taxes, and insurance) with the related lease component. Any variable nonlease components are not included within the lease right-of-use asset and lease liability on our Consolidated Balance Sheets, and instead, are reflected as an expense in the period incurred. Operating and financing lease right-of-use assets and lease liabilities as of December 31, 2024 and 2023 are as follows: DECEMBER 31, DESCRIPTION 2024 2023 Assets: Operating lease right-of-use assets (1) $ 2,489,893 $ 2,696,024 Financing lease right-of-use assets, net of accumulated depreciation (2)(3) 359,265 304,600 Liabilities: Current Operating lease liabilities $ 315,400 $ 291,795 Financing lease liabilities (3) 128,397 39,089 Long-term Operating lease liabilities $ 2,334,826 $ 2,562,394 Financing lease liabilities (3) 278,444 310,776 (1) At December 31, 2024 and 2023, these assets are comprised of approximately 99% real estate related assets (which include land, buildings, data center infrastructure and racking structures) and 1% non-real estate related assets (which include warehouse equipment, vehicles, furniture and fixtures and computer hardware and software). (2) At December 31, 2024, these assets are comprised of approximately 58% real estate related assets and 42% non-real estate related assets. At December 31, 2023, these assets are comprised of approximately 68% real estate related assets and 32% non-real estate related assets. (3) Financing lease right-of-use assets, current financing lease liabilities and long-term financing lease liabilities are included within Property, Plant and Equipment, Net, Current portion of long-term debt and Long-term Debt, net of current portion, respectively, within our Consolidated Balance Sheets. The components of the lease expense for the years ended December 31, 2024, 2023 and 2022 are as follows: YEAR ENDED DECEMBER 31, DESCRIPTION 2024 2023 2022 Operating lease cost (1) $ 682,960 $ 660,889 $ 574,115 Financing lease cost: Depreciation of financing lease right-of-use assets $ 50,548 $ 42,089 $ 42,708 Interest expense for financing lease liabilities 21,949 18,638 17,329 (1) Operating lease cost, the majority of which is included in Cost of sales, includes variable lease costs of $163,916, $142,154 and $119,184 for the years ended December 31, 2024, 2023 and 2022, respectively.

LONG-LIVED ASSETS We review long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be recoverable. Recoverability of these assets is determined by comparing the sum of the forecasted undiscounted net cash flows of the operation to which the assets relate to their carrying amount. The operations are generally distinguished by the business segment and geographic region in which they operate. If it is determined that we are unable to recover the carrying amount of the assets, the long-lived assets are written down, on a pro rata basis, to fair value. Fair value is determined based on discounted cash flows or appraised values, depending upon the nature of the assets. Long-lived assets, including finite-lived intangible assets, are amortized over their useful lives. Annually, or more frequently if events or circumstances warrant, we assess whether a change in the lives over which long-lived assets, including finite-lived intangible assets, are amortized is necessary. Loss (gain) on disposal/write-down of property, plant and equipment, net for the years ended December 31, 2024, 2023 and 2022 is as follows: YEAR ENDED DECEMBER 31, 2024 2023 2022 Loss (gain) on disposal/write-down of property, plant and equipment, net $ 6,196 $ (12,825) $ (93,268) Primarily consists of (1) : • Losses related to the disposal of assets associated with facility consolidations. • Gains associated with sale and sale-leaseback transactions of approximately $19,500, of which approximately $18,500 relates to a sale-leaseback transaction of a facility in Singapore during the first quarter of 2023. These gains are partially offset by losses related to the disposal of assets associated with facility consolidations. • Gains associated with sale and sale-leaseback transactions of approximately $94,500 , of which (i) approximately $49,000 relates to sale and sale-leaseback transactions of 11 facilities and parcels of land in the United States during the second quarter of 2022, (ii) approximately $17,000 relates to sale-leaseback transactions of two facilities in the United States and one in Canada during the third quarter of 2022 and (iii) approximately $28,500 relates to sale and sale-leaseback transactions of 12 facilities and one parcel of land in the United States and one facility in the United Kingdom during the fourth quarter of 2022. (1) L. GOODWILL AND OTHER INDEFINITE-LIVED INTANGIBLE ASSETS Goodwill and intangible assets with indefinite lives are not amortized but are reviewed annually for impairment, or more frequently if impairment indicators arise. Other than goodwill, we currently have no intangible assets that have indefinite lives and which are not amortized. We test goodwill annually on October 1, and more frequently if impairment indicators arise that would require an interim test. We have performed our annual goodwill impairment review as of October 1, 2024, 2023 and 2022. We concluded that as of October 1, 2024, 2023 and 2022, goodwill was not impaired. REPORTING UNITS AS OF OCTOBER 1, 2023 Our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2023 were as follows: • North America Records and Information Management ("North America RIM") • Europe Records and Information Management ("Europe RIM") • Middle East, North Africa, South Africa and Turkey Information Management ("MENATSA RIM") • Latin America Records and Information Management ("Latin America RIM") • Asia Pacific Records and Information Management ("APAC RIM") • Entertainment Services • Global Data Center • Fine Arts • ALM There were no changes to the composition of our reporting units between October 1, 2023 and December 31, 2023. GOODWILL BY REPORTING UNIT AS OF DECEMBER 31, 2023 The carrying value of goodwill, net for each of our reporting units described above as of December 31, 2023 is as follows: SEGMENT REPORTING UNIT CARRYING VALUE AS OF DECEMBER 31, 2023 Global RIM Business North America RIM $ 2,694,093 Europe RIM 541,860 MENATSA RIM 26,502 Latin America RIM 120,119 APAC RIM 496,944 Entertainment Services 32,427 Global Data Center Business Global Data Center 478,930 Corporate and Other Fine Arts 47,535 ALM 579,502 Total $ 5,017,912 2024 REPORTING UNIT CHANGES During 2024, as a result of the realignment of our global managerial structure, we reassessed the composition of our reporting units. The realignment of our global managerial structure did not change the composition of our reportable segments (as described and defined in Note 11). As a result of the reassessment, our businesses that were previously managed under our former MENATSA RIM reporting unit are now managed as part of our "Europe RIM" reporting unit. Additionally, our former Entertainment Services reporting unit is now referred to as "Media and Archive Services" to more accurately reflect the offerings of this business. There were no changes to our other reporting units. REPORTING UNITS AS OF OCTOBER 1, 2024 Our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2024 were as follows: • North America RIM • Europe RIM • Latin America RIM • APAC RIM • Media and Archive Services • Global Data Center • Fine Arts • ALM There were no changes to the composition of our reporting units between October 1, 2024 and December 31, 2024. GOODWILL BY REPORTING UNIT AS OF DECEMBER 31, 2024 The carrying value of goodwill, net for each of our reporting units described above as of December 31, 2024 is as follows: SEGMENT REPORTING UNIT CARRYING VALUE AS OF DECEMBER 31, 2024 Global RIM Business North America RIM $ 2,675,999 Europe RIM 542,521 Latin America RIM 99,599 APAC RIM 467,059 Media and Archive Services 31,696 Global Data Center Business Global Data Center 469,461 Corporate and Other Fine Arts 47,925 ALM 749,557 Total $ 5,083,817 The fair value of our reporting units has generally been determined using a combined approach based on the present value of future cash flows (the "Discounted Cash Flow Model") and market multiples (the "Market Approach"). The Discounted Cash Flow Model incorporates significant assumptions including future revenue growth rates, operating margins, discount rates and capital expenditures. The Market Approach requires us to make assumptions related to Adjusted EBITDA (as defined in Note 11) multiples. Changes in economic and operating conditions impacting these assumptions or changes in multiples could result in goodwill impairments in future periods. In conjunction with our annual goodwill impairment reviews, we reconcile the sum of the valuations of all of our reporting units to our market capitalization as of such dates. The changes in the carrying value of goodwill attributable to each reportable segment for the years ended December 31, 2024 and 2023 are as follows: GLOBAL RIM GLOBAL CORPORATE TOTAL Goodwill balance, net of accumulated amortization, as of December 31, 2022 $ 3,852,946 $ 418,502 $ 611,286 $ 4,882,734 Tax deductible goodwill acquired during the year — — 11,928 11,928 Non-tax deductible goodwill acquired during the year 21,594 56,674 383 78,651 Fair value and other adjustments (80) — 2,333 2,253 Currency effects 37,485 3,754 1,107 42,346 Goodwill balance, net of accumulated amortization, as of December 31, 2023 3,911,945 478,930 627,037 5,017,912 Tax deductible goodwill acquired during the year — — 132,891 132,891 Non-tax deductible goodwill acquired during the year — — 39,646 39,646 Fair value and other adjustments 372 (186) (186) — Currency effects (95,443) (9,283) (1,906) (106,632) Goodwill balance, net of accumulated amortization, as of December 31, 2024 $ 3,816,874 $ 469,461 $ 797,482 $ 5,083,817 Accumulated Goodwill Impairment Balance as of December 31, 2023 $ 132,409 $ — $ 26,011 $ 158,420 Accumulated Goodwill Impairment Balance as of December 31, 2024 $ 132,409 $ — $ 26,011 $ 158,420 M. FINITE-LIVED INTANGIBLE ASSETS AND LIABILITIES I. CUSTOMER AND SUPPLIER RELATIONSHIP INTANGIBLE ASSETS Customer and supplier relationship intangible assets, which are acquired through either business combinations or acquisitions of customer relationships, are generally amortized over periods ranging from 10 to 30 years. Customer and supplier relationship intangible assets are recorded based upon estimates of their fair value. II. CUSTOMER INDUCEMENTS Payments that are made to a customer in order to terminate the customer’s storage of records with its current records management vendor ("Permanent Withdrawal Fees"), or direct payments to a customer for which no distinct benefit is received in return, are collectively referred to as "Customer Inducements". Customer Inducements are treated as a reduction of the transaction price over the associated contract terms, which range from one III. DATA CENTER INTANGIBLE ASSETS AND LIABILITIES Finite-lived intangible assets associated with our Global Data Center Business consist of the following: DATA CENTER IN-PLACE LEASE INTANGIBLE ASSETS AND DATA CENTER TENANT RELATIONSHIP INTANGIBLE ASSETS Data center in-place lease intangible assets ("Data Center In-Place Leases") and data center tenant relationship intangible assets ("Data Center Tenant Relationships") reflect the value associated with acquiring a data center operation with active tenants as of the date of acquisition. The value of Data Center In-Place Leases is determined based upon an estimate of the economic costs (such as lost revenues, tenant improvement costs, commissions, legal expenses and other costs to acquire new data center leases) avoided by acquiring a data center operation with active tenants. Data Center In-Place Leases are amortized over the weighted average remaining term of the acquired data center leases. The value of Data Center Tenant Relationships is determined based upon an estimate of the economic costs avoided upon lease renewal of the acquired tenants, based upon expectations of lease renewal. Data Center Tenant Relationships are amortized over the weighted average remaining anticipated life of the relationship with the acquired tenant. DATA CENTER ABOVE-MARKET AND BELOW-MARKET IN-PLACE LEASE INTANGIBLE ASSETS Data center above-market in-place lease intangible assets ("Data Center Above-Market Leases") and data center below-market in-place lease intangible assets ("Data Center Below-Market Leases") are recorded at the net present value of the difference between (i) the contractual amounts to be paid pursuant to each in-place lease and (ii) management’s estimate of the fair market lease rates for each corresponding in-place lease. Data Center Above-Market Leases and Data Center Below-Market Leases are amortized over the remaining non-cancellable term of the acquired in-place lease to storage revenue. The gross carrying amount and accumulated amortization of our finite-lived intangible assets as of December 31, 2024 and 2023, respectively, are as follows: DECEMBER 31, 2024 DECEMBER 31, 2023 DESCRIPTION GROSS CARRYING AMOUNT ACCUMULATED AMORTIZATION NET CARRYING AMOUNT GROSS CARRYING AMOUNT ACCUMULATED AMORTIZATION NET CARRYING AMOUNT Assets: Customer and supplier relationship intangible assets (1) $ 2,268,949 $ (1,035,846) $ 1,233,103 $ 2,144,641 $ (933,084) $ 1,211,557 Customer inducements (1) 38,782 (19,706) 19,076 47,565 (25,562) 22,003 Data center lease-based intangible assets (1)(2) 138,714 (116,162) 22,552 141,628 (95,422) 46,206 Third-party commissions asset and other (3) 86,314 (51,508) 34,806 77,638 (39,323) 38,315 Liabilities: Data center below-market leases (4) $ 10,819 $ (7,275) $ 3,544 $ 10,873 $ (5,772) $ 5,101 (1) Included in Customer and supplier relationship and other intangible assets in the accompanying Consolidated Balance Sheets.

Amortization expense associated with finite-lived intangible assets, revenue reduction associated with the amortization of Customer Inducements and net revenue reduction associated with the amortization of Data Center Above-Market Leases and Data Center Below-Market Leases for the years ended December 31, 2024, 2023 and 2022 is as follows: YEAR ENDED DECEMBER 31, 2024 2023 2022 Amortization expense included in depreciation and amortization associated with: Customer and supplier relationship intangible assets $ 155,872 $ 153,128 $ 156,779 Data center in-place leases and tenant relationships 22,304 22,322 16,955 Third-party commissions asset and other 16,478 12,541 16,148 Revenue reduction associated with amortization of: Customer inducements and data center above-market and below-market leases $ 5,347 $ 7,036 $ 8,119 Estimated amortization expense for existing finite-lived intangible assets (excluding Contract Costs, as defined in Note 2.s.) is as follows: ESTIMATED AMORTIZATION YEAR INCLUDED IN DEPRECIATION REVENUE REDUCTION ASSOCIATED WITH CUSTOMER INDUCEMENTS 2025 $ 178,310 $ 4,493 2026 150,079 3,887 2027 131,057 2,838 2028 121,642 1,400 2029 107,935 1,114 Thereafter 601,323 1,915 N. DEFERRED FINANCING COSTS Deferred financing costs are amortized over the life of the related debt. If debt is retired early, the related unamortized deferred financing costs are written off in the period the debt is retired and included as a component of Other expense (income), net. See Note 7. O. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES Derivative instruments are measured at fair value and are recorded as either assets or liabilities in our Consolidated Balance Sheets. Periodically, we acquire derivative instruments that are intended to hedge either cash flows or values that are subject to foreign exchange or other market price risk and not for trading purposes. We have formally documented our hedging relationships, including identification of the hedging instruments and the hedged items, as well as our risk management objectives and strategies for undertaking each hedge transaction concurrently with the execution of the derivative instrument. Given the recurring nature of our revenues and the long-term nature of our asset base, we have the ability and the preference to use long-term, fixed interest rate debt to finance our business, thereby preserving our long-term returns on invested capital. We may use interest rate swaps as a tool to maintain our targeted level of fixed rate debt. In addition, we may enter into cross-currency swaps to hedge the variability of exchange rates between the United States dollar and the currencies of our foreign subsidiaries, as well as interest rates. We may also use borrowings in foreign currencies, either obtained in the United States or by our foreign subsidiaries, to hedge foreign currency risk associated with our international investments. Gains and losses realized as a result of the maturing or termination of our interest rate swaps and cross-currency swaps are reflected as operating cash flows within our Consolidated Statements of Cash Flows. As of December 31, 2024 and 2023, none of our derivative instruments contained credit-risk related contingent features. See Note 6. P. FAIR VALUE MEASUREMENTS Entities are permitted under GAAP to elect to measure certain financial instruments and certain other items at either fair value or cost. We have elected the cost measurement option in all circumstances where we had an option. Our financial assets or liabilities that are carried at fair value are required to be measured using inputs from the three levels of the fair value hierarchy. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The three levels of the fair value hierarchy are as follows: Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access at the measurement date. Level 2—Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.), and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs). Level 3—Unobservable inputs that reflect our assumptions about the assumptions that market participants would use in pricing the asset or liability. The assets and liabilities carried at fair value and measured on a recurring basis as of December 31, 2024 and 2023, respectively, are as follows: FAIR VALUE MEASUREMENTS AT DECEMBER 31, 2024 USING DESCRIPTION TOTAL CARRYING VALUE AT DECEMBER 31, 2024 QUOTED PRICES IN SIGNIFICANT OTHER SIGNIFICANT UNOBSERVABLE INPUTS (LEVEL 3) (6) Money Market Funds (1) $ 2,488 $ — $ 2,488 $ — Time Deposits (1) 9,612 — 9,612 — Trading Securities 8,144 6,390 (2) 1,754 (3) — Derivative Assets (4) 28,092 — 28,092 — Derivative Liabilities (4) 5,326 — 5,326 — Deferred Purchase Obligations (5) 147,055 — — 147,055 FAIR VALUE MEASUREMENTS AT DECEMBER 31, 2023 USING DESCRIPTION TOTAL CARRYING VALUE AT DECEMBER 31, 2023 QUOTED PRICES IN SIGNIFICANT OTHER SIGNIFICANT UNOBSERVABLE INPUTS (LEVEL 3) (6) Money Market Funds (1) $ 66,008 $ — $ 66,008 $ — Time Deposits (1) 15,913 — 15,913 — Trading Securities 9,952 6,149 (2) 3,

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Acquisitions	We account for acquisitions using the acquisition method of accounting, and, accordingly, the assets and liabilities acquired are recorded at their estimated fair values and the results of operations for each acquisition have been included in our consolidated results from their respective acquisition dates. A. ACQUISITIONS COMPLETED DURING THE YEAR ENDED DECEMBER 31, 2024 REGENCY TECHNOLOGIES On January 3, 2024, in order to expand our ALM business, we acquired 100% of RSR Partners, LLC (doing business as Regency Technologies), an IT asset disposition services provider with operations throughout the United States, for an initial purchase price of approximately $200,000, subject to certain working capital adjustments at, and subsequent to, the closing, with $125,000 paid at closing, funded by borrowings under the Revolving Credit Facility, and the remaining $75,000 (the "January 2025 Payment"), paid in January 2025 (the "Regency Transaction"). The present value of the January 2025 Payment is included as a component of Accrued expenses and other current liabilities in our Consolidated Balance Sheet at December 31, 2024. The agreement for the Regency Transaction also includes a performance-based contingent consideration with a potential earnout range from zero to $200,000 based upon achievement of certain three-year cumulative revenue targets, which would be payable in 2027, if earned. The preliminary fair value estimate of this deferred purchase obligation as of the acquisition date was approximately $78,400. See Note 2.p. for details on the methodology used to establish the fair value. The fair value of the deferred purchase obligation is included as a component of Other long-term liabilities in our Consolidated Balance Sheet at December 31, 2024. Subsequent increases or decreases in the fair value estimate of the deferred purchase obligation, as well as the accretion of the discount to present value, is included as a component of Other expense (income), net in our Consolidated Statements of Operations until the deferred purchase obligation is settled or paid. Subsequent to the acquisition, the results of Regency Technologies are included as a component of Corporate and Other (as defined in Note 11). B. ACQUISITIONS COMPLETED DURING THE YEAR ENDED DECEMBER 31, 2023 WEB WERKS On July 7, 2023, we made our final contractual investment in a joint venture with the shareholders of Web Werks India Private Limited (the "Web Werks JV") of approximately 3,750,000 Indian rupees (or approximately $45,300, based upon the exchange rate between the United States dollar and Indian rupee on the closing date of this investment). As a result of this transaction, our interest in the Web Werks JV increased to 63.39%, we assumed control of its board of directors and the financial results of the Web Werks JV are consolidated within our Global Data Center Business segment. We recognized noncontrolling interests of approximately $78,600 based upon the fair value attributable to these interests at the time of this transaction, of which approximately $18,100 of the noncontrolling interests were determined to be a current liability and included as a component of Accrued expenses and other current liabilities on our Consolidated Balance Sheet at December 31, 2023. On July 1, 2024, we entered into an agreement with the minority shareholders of Web Werks India Private Limited to acquire the remaining approximately 36.61% interest in the Web Werks JV in two separate transactions. As a result of the agreement, during the third quarter of 2024, we recognized a charge of approximately $29,200, which is included as a component of Other expense (income), net in our Consolidated Statement of Operations for the year ended December 31, 2024. On July 5, 2024, we completed the acquisition of an approximately 8.55% interest in the Web Werks JV ("Tranche I") for approximately 3,000,000 Indian rupees (or approximately $35,000, based upon the exchange rate between the United States dollar and the Indian rupee on the closing date of Tranche I). Subsequent to the Tranche I payment, our ownership interest in the Web Werks JV is approximately 71.94%. In March 2025, we will be required to make an additional payment of approximately 9,600,000 Indian rupees (or approximately $112,200, based upon the exchange rate between the United States dollar and the Indian rupee as of December 31, 2024) to acquire the remaining approximately 28.06% interest in the Web Werks JV ("Tranche II"). As part of the Tranche II payment in March 2025, we may also make an incremental payment of approximately 1,000,000 Indian rupees (or approximately $11,700, based upon the exchange rate between the United States dollar and the Indian rupee as of December 31, 2024) (the "Incremental Payment") if certain infrastructure goals are achieved before December 31, 2024. We are currently assessing the achievement of these goals. The liability associated with Tranche II and our current estimate of the Incremental Payment is included within Accrued expenses and other current liabilities in our Consolidated Balance Sheet at December 31, 2024. CLUTTER In February 2022, the joint venture formed by MakeSpace Labs, Inc. and us (the "MakeSpace JV") entered into an agreement with Clutter, Inc. pursuant to which the equityholders of the MakeSpace JV contributed their ownership interests in the MakeSpace JV, and Clutter, Inc.’s shareholders contributed their ownership interests in Clutter, Inc., to create a newly formed venture (the "Clutter JV"). In exchange for our 49.99% interest in the MakeSpace JV, we received an approximately 27% interest in the Clutter JV (the "Clutter Transaction"). As a result of the Clutter Transaction, we recognized a gain related to our contributed interest in the MakeSpace JV of approximately $35,800, which was recorded to Other, net, a component of Other expense (income), net during the year ended December 31, 2022. On June 29, 2023, in order to further expand our on-demand consumer storage business, we acquired 100% of the outstanding shares of Clutter Intermediate, Inc. and control of all assets of the Clutter JV (collectively, "Clutter") for total consideration of $60,600 (the "Clutter Acquisition"). Our previously held approximately 27% interest in the Clutter JV was remeasured to fair value at the closing date of the Clutter Acquisition. As a result, we recognized a loss of approximately $38,000 to Other, net, a component of Other expense (income), net, during the second quarter of 2023. The financial results of the Clutter JV are now consolidated within our Global RIM Business segment. In October 2023, we sold 15% of the equity interests in Clutter to certain former stakeholders of the Clutter JV for a total consideration of $7,500, which represents the fair value attributable to these interests, which is included as a component of Redeemable Noncontrolling Interests on our Consolidated Balance Sheet at December 31, 2023. C. ACQUISITIONS COMPLETED DURING THE YEAR ENDED DECEMBER 31, 2022 ITRENEW On January 25, 2022, in order to expand our ALM operations, we acquired an approximately 80% interest in ITRenew at an agreed upon purchase price of $725,000, subject to certain working capital adjustments at, and subsequent to, the closing (the "ITRenew Transaction"). At closing, we paid $748,846 and acquired $30,720 of cash on hand, for a net purchase price of $718,126 for the ITRenew Transaction. The acquisition agreement includes a deferred purchase obligation that provides us the option to purchase, and provides the shareholders of ITRenew the option to sell, the remaining approximately 20% interest in ITRenew as follows: (i) approximately 16% on or after the second anniversary of the ITRenew Transaction and (ii) approximately 4% on or after the third anniversary of the ITRenew Transaction (collectively, the "Remaining Interests"). The total payments for the Remaining Interests, based on the achievement of certain targeted performance metrics, will be no less than $200,000 and no more than $531,000. From January 25, 2022, we consolidate 100% of the revenues and expenses associated with this business. The current and long-term portions of the deferred purchase obligation are reflected as components of Accrued expenses and other current liabilities and Other long-term liabilities, respectively, in our Consolidated Balance Sheet at December 31, 2023. The deferred purchase obligation is reflected as a component of Accrued expenses and other current liabilities in our Consolidated Balance Sheet at December 31, 2024. We have not reflected any non-controlling interests associated with the ITRenew Transaction as the Remaining Interests have non-substantive equity interest rights. Subsequent increases or decreases in the fair value estimate of the deferred purchase obligation are included as a component of Other expense (income), net in our Consolidated Statements of Operations until the deferred purchase obligation is settled or paid. See Note 2.v. The unaudited consolidated pro forma financial information (the "Pro Forma Financial Information") below summarizes the combined results of Iron Mountain and ITRenew on a pro forma basis as if the ITRenew Transaction had occurred on January 1, 2021. The Pro Forma Financial Information is presented for informational purposes and is not necessarily indicative of the results of operations that would have been achieved if the acquisition had taken place on January 1, 2021. The Pro Forma Financial Information, for the periods presented, includes purchase accounting adjustments (including amortization of acquired customer and supplier intangible assets and depreciation of acquired property, plant and equipment) and related tax effects. Through December 31, 2022, we and ITRenew collectively incurred $59,370 of operating expenditures to complete the ITRenew Transaction (including advisory and professional fees). These operating expenditures have been reflected within the results of operations in the Pro Forma Financial Information as if they were incurred on January 1, 2021. YEAR ENDED DECEMBER 31, 2022 Total Revenues $ 5,121,548 Income from Continuing Operations 571,381 In addition to our acquisition of ITRenew, we completed certain other acquisitions during the years ended December 31, 2024, 2023 and 2022. The Pro Forma Financial Information does not reflect these acquisitions due to the insignificant impact of these acquisitions on our consolidated results of operations. XDATA PROPERTIES On October 5, 2022, in order to further expand our data center operations in Europe, we completed the acquisition of XData Properties S.L.U., a data center colocation space and solutions provider with a data center in Spain, which we accounted for as an asset acquisition, for (i) cash consideration of 78,900 Euros (or approximately $78,200, based upon the exchange rate between the Euro and the United States dollar on the closing date of this acquisition), subject to adjustments, and (ii) up to 10,000 Euros (or approximately $9,900, based upon the exchange rate between the Euro and the United States dollar on the closing date of this acquisition) of additional consideration, payable based on the achievement of certain power connection milestones through December 2024. In January 2025, a payment was made for the milestones that were achieved. D. PURCHASE PRICE ALLOCATION A summary of the cumulative consideration paid and the allocation of the purchase price paid for all of our acquisitions (including asset acquisitions) in each respective year is as follows: 2024 2023 2022 TOTAL TOTAL ITRENEW OTHER FISCAL YEAR 2022 ACQUISITIONS TOTAL Cash Paid (gross of cash acquired) (1) $ 185,882 $ 88,635 $ 749,596 $ 85,170 $ 834,766 Fair Value of Noncontrolling Interests (2) — 78,598 — — — Fair Value of Previously Held Equity Interest (2) — 99,718 — — — Deferred Purchase Obligations, Purchase Price Holdbacks and Other (3) 134,638 4,790 275,100 13,637 288,737 Settlement of Pre-Existing Relationships — 21,641 — — — Total Consideration 320,520 293,382 1,024,696 98,807 1,123,503 Fair Value of Identifiable Assets Acquired and Liabilities Assumed: Cash and Cash Equivalents 9,843 49,716 30,694 963 31,657 Accounts Receivable, Prepaid Expenses and Other Assets 24,872 36,274 71,612 3,947 75,559 Property, Plant and Equipment 12,320 140,668 7,541 93,722 101,263 Customer and Supplier Relationship Intangible Assets (4) 131,463 14,330 487,600 3,672 491,272 Other Intangible Assets 140 8,046 47,300 1,442 48,742 Operating Lease Right-of-Use Assets 38,037 29,046 29,545 3,135 32,680 Debt Assumed — (22,413) — — — Accounts Payable, Accrued Expenses and Other Liabilities (36,786) (19,323) (60,157) (2,069) (62,226) Operating Lease Liabilities (26,925) (29,046) (29,545) (3,135) (32,680) Deferred Income Taxes (4,981) (4,495) (100,922) (10,143) (111,065) Total Fair Value of Identifiable Net Assets Acquired 147,983 202,803 483,668 91,534 575,202 Goodwill Initially Recorded $ 172,537 $ 90,579 $ 541,028 $ 7,273 $ 548,301 (1) Cash paid for acquisitions, net of cash acquired in our Consolidated Statements of Cash Flows includes contingent and other payments of $2,375, $2,930 and $581 for the years ended December 31, 2024, 2023 and 2022, respectively, related to acquisitions made in the years prior to 2024, 2023 and 2022, respectively. (2) The fair values of the noncontrolling interests and the previously held equity interest were determined to be the respective interest’s proportionate share of the fair value of net assets acquired as of the acquisition date. (3) In 2024, Deferred purchase obligations, purchase price holdbacks and other consists of the acquisition-date fair values of the deferred purchase obligation associated with the Regency Transaction and the January 2025 Payment. In 2022, Deferred purchase obligations, purchase price holdbacks and other includes $275,100 related to the original fair value estimate of the deferred purchase obligation for the Remaining Interests. (4) The weighted average lives of customer and supplier relationship intangible assets associated with acquisitions in 2024, 2023 and 2022 were 20 years, four years and 12 years, respectively. Allocations of the purchase price for acquisitions are based on estimates of the fair value of the net assets acquired and are subject to adjustment upon the finalization of the purchase price allocations. The accounting for business combinations requires estimates and judgments regarding expectations for future cash flows of the acquired business, and the allocations of those cash flows to identifiable tangible and intangible assets, in determining the assets acquired and liabilities assumed. The fair values assigned to tangible and intangible assets acquired and liabilities assumed, including contingent consideration, are based on management’s best estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary valuation procedures and techniques. The estimates and assumptions underlying the initial valuations are subject to the collection of information necessary to complete the valuations within the measurement periods, which are up to one year from the respective acquisition dates. As the valuation of certain assets and liabilities for purposes of purchase price allocations are preliminary in nature, they are subject to adjustment as additional information is obtained about the facts and circumstances regarding these assets and liabilities that existed at the acquisition date. The preliminary purchase price allocations that are not finalized as of December 31, 2024 relate to the final assessment of the fair values of property, plant and equipment and intangible assets associated with the acquisitions we closed during the year ended December 31, 2024. Any adjustments to our estimates of purchase price allocation will be made in the periods in which the adjustments are determined and the cumulative effect of such adjustments will be calculated as if the adjustments had been completed as of the acquisition dates. Purchase price allocation adjustments recorded during the fourth quarter of 2024 and year ended December 31, 2024 were not material to our balance sheet or results from operations.

Discontinued Operations and Disposal Groups [Abstract]
Deconsolidation	DECONSOLIDATION On March 24, 2022, as a result of our loss of control, we deconsolidated the businesses included in our acquisition of OSG Records Management (Europe) Limited, excluding Ukraine (the "OSG Deconsolidation"). We recognized a loss of approximately $105,800 associated with the deconsolidation to Other expense (income), net in the first quarter of 2022 representing the difference between the net asset value prior to the deconsolidation and the subsequent remeasurement of the retained investment to a fair value of zero. We have concluded that the deconsolidation does not meet the criteria to be reported as discontinued operations in our consolidated financial statements, as it does not represent a strategic shift that will have a major effect on our operations and financial results.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	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 (the "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. In April 2023, in anticipation of the discontinuance of the LIBOR reference rate on June 30, 2023, we terminated interest rate swap agreements with notional amounts totaling $350,000 that were indexed to the one-month LIBOR benchmark rate. The terminated swap agreements had associated unrealized gains at the termination date of approximately $10,100. These gains were included in Accumulated other comprehensive items, net and have been reclassified into earnings as reductions to interest expense from the termination date through March 2024, the original maturity date of these interest rate swap agreements. As of December 31, 2024 and 2023, we have approximately $1,482,000 and $520,000, respectively, in notional value outstanding on our interest rate swap agreements. As of December 31, 2024, our interest rate swap agreements have maturity dates ranging from October 2025 through May 2027. CROSS-CURRENCY SWAP AGREEMENTS DESIGNATED AS A HEDGE OF NET INVESTMENT We utilize cross-currency interest rate 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 December 31, 2024, our cross-currency interest rate swap agreements have maturity dates ranging from August 2025 through November 2026. The notional values of our cross-currency interest rate swaps, by currency, as of December 31, 2024 and 2023 are as follows: YEAR ENDED DECEMBER 31, 2024 2023 Euro $ 509,187 $ 509,187 Canadian dollar 350,000 — $ 859,187 $ 509,187 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. The fair value of derivative instruments recognized in our Consolidated Balance Sheets as of December 31, 2024 and 2023, by derivative instrument, are as follows: DERIVATIVE INSTRUMENTS (1) DECEMBER 31, 2024 DECEMBER 31, 2023 Assets Liabilities Assets Liabilities Cash Flow Hedges (2) Interest rate swap agreements $ 1,887 $ (5,326) $ 1,601 $ (3,273) Net Investment Hedges (3) Cross-currency swap agreements 26,205 — 4,758 (2,496) (1) Our derivative assets are included as a component of (i) Prepaid expenses and other or (ii) Other within Other assets, net and our derivative liabilities are included as a component of (i) Accrued expenses and other current liabilities or (ii) Other long-term liabilities in our Consolidated Balance Sheets.

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 due 2031"). The Credit Agreement also included a second term loan B facility (the "Term Loan B due 2026") until its extinguishment in August 2024. During the year ended December 31, 2024, we took the following actions regarding our Credit Agreement: • On June 7, 2024, due to the discontinuance of the Canadian Dollar Offered Rate reference rate on June 28, 2024, we amended the Credit Agreement to update the interest rate benchmark available for Canadian currency borrowings under our Revolving Credit Facility to the Canadian Overnight Repo Rate Average, effective July 1, 2024. • On July 2, 2024, we amended the Credit Agreement, which resulted in: ◦ an increase in the principal amount of the Term Loan B due 2031 from approximately $1,194,000 to approximately $1,806,700, ◦ a decrease in the interest rate of the Term Loan B due 2031 from the SOFR plus 2.25% to the SOFR plus 2.00% and ◦ a decrease in the principal amount of our Term Loan B due 2026 from approximately $656,300 to approximately $53,400. • In connection with the July 2, 2024 amendment, we paid original issue discount fees of approximately $4,300, and we recorded a charge to Other expense (income), net related to the extinguishment of debt. • On August 19, 2024, we: ◦ repaid the remaining approximately $53,400 principal balance of the Term Loan B due 2026 and ◦ amended the Credit Agreement to increase the principal amount of the Term Loan B due 2031 from approximately $1,806,700 to approximately $1,860,000. • On November 7, 2024, we amended the Credit Agreement, which resulted in: ◦ an extension of the maturity date of the Revolving Credit Facility and the Term Loan A from March 18, 2027 to March 18, 2030, ◦ a decrease in the principal amount of the Term Loan A from $250,000 to $218,750, ◦ an increase of the borrowing capacity that IMI and certain of its United States and foreign subsidiaries are able to borrow under the Revolving Credit Facility from $2,250,000 to $2,750,000 and ◦ the removal of the 10 basis point credit spread adjustment applicable to the Revolving Credit Facility and Term Loan A. 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, 2024, is to be paid in quarterly installments in an amount equal to approximately $2,700 per quarter. The Term Loan B due 2031 is scheduled to mature on January 31, 2031, at which point all obligations become due. The Term Loan B due 2031, which was fully drawn as of December 31, 2024, is to be paid in quarterly installments in an amount equal to approximately $4,700 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 bears interest at the SOFR plus 1.75%. The Term Loan B due 2026 bore interest at the synthetic LIBOR rate plus 1.75% until its extinguishment in August 2024. 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, 2024, we had $121,000, $216,016 and $1,850,698 outstanding under the Revolving Credit Facility, Term Loan A and the Term Loan B due 2031, respectively. As of December 31, 2024, we had various outstanding letters of credit totaling $7,766 under the Revolving Credit Facility. The remaining amount available for borrowing under the Revolving Credit Facility as of December 31, 2024, 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 $2,621,234 (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 rate in effect under the Revolving Credit Facility as of December 31, 2024 was 6.3%. The interest rates in effect under the Term Loan A as of December 31, 2024 and 2023 were 6.1% and 7.2%, respectively. The interest rate in effect under the Term Loan B due 2026 as of December 31, 2023 was 5.2%. The interest rates in effect under the Term Loan B due 2031 as of December 31, 2024 and 2023 were 6.4% and 7.6%, respectively.

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. On June 14, 2024, we amended the Accounts Receivable Securitization Program to (i) increase the maximum borrowing capacity from $360,000 to $400,000 and (ii) extend the maturity date from July 1, 2025 to July 1, 2027, at which point all obligations become due. As of December 31, 2024 and 2023, the amount outstanding under the Accounts Receivable Securitization Program was $400,000 and $358,500, respectively. The interest rate in effect under the Accounts Receivable Securitization Program was 5.6% and 6.4% as of December 31, 2024 and 2023, 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 OUTSTANDING BORROWINGS $400,000 5.6% Interest rate As of December 31, 2024 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, 2024 and 2023 are reflected as Cash and cash equivalents in our Consolidated Balance Sheets. H. LETTERS OF CREDIT As of December 31, 2024, we had outstanding letters of credit totaling $64,147, of which $7,766 reduce our borrowing capacity under the Revolving Credit Facility (as described above). The letters of credit expire at various dates between March 2025 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, 2024. Noncompliance with these leverage and fixed charge coverage ratios would have a material adverse effect on our financial condition and liquidity. J.

Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES A. PURCHASE COMMITMENTS We have certain contractual obligations related to purchase commitments which require minimum payments as follows: YEAR PURCHASE COMMITMENTS (1) 2025 $ 74,975 2026 50,559 2027 94,489 2028 28,174 2029 10,201 Thereafter 9,483 $ 267,881 (1) Purchase commitments (i) include obligations related principally to software maintenance and support services and (ii) exclude our operating and financing lease obligations (see Note 2.j.) and our deferred purchase obligations (see Note 2.p.). In addition to the above, as of December 31, 2024, we have contractual commitments of approximately $886,900 for future construction costs associated with the expansion of our Global Data Center Business that are expected to be incurred over the next one B. SELF-INSURED LIABILITIES We are self-insured up to certain limits for costs associated with workers’ compensation claims, vehicle accidents, property and general business liabilities and benefits paid under employee healthcare and short-term disability programs. At December 31, 2024 and 2023, there were approximately $45,200 and $42,500, respectively, of self-insurance accruals reflected in Accrued expenses on our Consolidated Balance Sheets. The measurement of these costs requires the consideration of historical cost experience and judgments about the present and expected levels of cost per claim. We account for these costs primarily through actuarial methods, which develop estimates of the undiscounted liability for claims incurred, including those claims incurred but not reported. These methods provide estimates of future claim costs based on claims incurred as of the balance sheet date. C. LITIGATION—GENERAL

The amount and timing of future dividends will continue to be subject to the approval of our board of directors, in its sole discretion, and to applicable legal requirements. In 2022, 2023 and 2024, our board of directors declared the following dividends: DECLARATION DATE DIVIDEND RECORD DATE TOTAL AMOUNT PAYMENT DATE February 24, 2022 $ 0.6185 March 15, 2022 $ 179,661 April 6, 2022 April 28, 2022 0.6185 June 15, 2022 179,781 July 6, 2022 August 4, 2022 0.6185 September 15, 2022 179,790 October 4, 2022 November 3, 2022 0.6185 December 15, 2022 179,866 January 5, 2023 February 23, 2023 0.6185 March 15, 2023 180,339 April 5, 2023 May 4, 2023 0.6185 June 15, 2023 180,493 July 6, 2023 August 3, 2023 0.6500 September 15, 2023 189,730 October 5, 2023 November 2, 2023 0.6500 December 15, 2023 189,886 January 4, 2024 February 22, 2024 0.6500 March 15, 2024 190,506 April 4, 2024 May 2, 2024 0.6500 June 17, 2024 190,643 July 5, 2024 August 1, 2024 0.7150 September 16, 2024 209,776 October 3, 2024 November 6, 2024 0.7150 December 16, 2024 209,913 January 7, 2025 On February 13, 2025, we declared a dividend to our stockholders of record as of March 17, 2025 of $0.7850 per share, payable on April 4, 2025. During the years ended December 31, 2024, 2023 and 2022, we declared dividends in an aggregate and per share amount, based on the weighted average number of common shares outstanding during each respective year, as follows: YEAR ENDED DECEMBER 31, 2024 2023 2022 Declared distributions $ 800,838 $ 740,448 $ 719,098 Amount per share each distribution represents based on weighted average number of common shares outstanding 2.73 2.54 2.47 For federal income tax purposes, distributions to our stockholders are generally treated as nonqualified ordinary dividends (potentially eligible for the lower effective tax rates available for "qualified REIT dividends"), qualified ordinary dividends or return of capital. The United States Internal Revenue Service requires historical C corporation earnings and profits to be distributed prior to any REIT distributions, which may affect the character of each distribution to our stockholders, including whether and to what extent each distribution is characterized as a qualified or nonqualified ordinary dividend. In addition, certain of our distributions qualify as capital gain distributions. For the years ended December 31, 2024, 2023 and 2022, the dividends we paid on our common shares were classified as follows: YEAR ENDED DECEMBER 31, 2024 2023 2022 Nonqualified ordinary dividends 82.6 % 98.2 % 90.4 % Qualified ordinary dividends (1) — % 0.8 % — % Capital gains (2) — % — % 9.6 % Return of capital 17.4 % 1.0 % — % 100.0 % 100.0 % 100.0 % (1) During the year ended December 31, 2023, the percentage of our dividends that was classified as qualified ordinary dividends for federal income tax purposes primarily related to the distribution of historical C corporation earnings and profits during the year ended December 31, 2023. (2) During the year ended December 31, 2022, the percentage of our dividends that was classified as capital gains primarily related to the sale of land and buildings in the United States and Canada. NONCONTROLLING INTERESTS During the quarter ended September 30, 2024, a put option available to our partner in our Iron Mountain Data Centers Virginia 4/5 JV, LP joint venture expired, triggering a change in the presentation of the related noncontrolling interest. Prior to September 30, 2024, the noncontrolling interest of approximately $53,400 was presented as Redeemable noncontrolling interests in our Consolidated Balance Sheets. Our partner's interest is now presented as Noncontrolling interests in our Consolidated Balance Sheet. During the quarter ended September 30, 2024, we entered into an agreement with a partner to form our Iron Mountain Data Centers Virginia 6/7 JV, LLC joint venture, which resulted in an initial Noncontrolling interest of approximately $103,100 recorded in our Consolidated Balance Sheet at September 30, 2024.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES We have been organized and have operated as a REIT effective beginning with our taxable year that ended on December 31, 2014. As a REIT, we are generally permitted to deduct from our federal taxable income the dividends we pay to our stockholders. The income represented by such dividends is not subject to federal taxation at the entity level but is taxed, if at all, at the stockholder level. The income of our domestic TRSs, which hold our domestic operations that may not be REIT-compliant as currently operated and structured, is subject, as applicable, to federal and state corporate income tax. In addition, we and our subsidiaries continue to be subject to foreign income taxes in other jurisdictions in which we have business operations or a taxable presence, regardless of whether assets are held or operations are conducted through subsidiaries disregarded for federal income tax purposes or TRSs. We will also be subject to a separate corporate income tax on any gains recognized on the sale or disposition of any asset previously owned by a C corporation during a five-year period after the date we first owned the asset as a REIT asset that are attributable to "built-in gains" with respect to that asset on that date. We will also be subject to a built-in gains tax on our depreciation recapture recognized into income as a result of accounting method changes in connection with our acquisition activities. If we fail to remain qualified for taxation as a REIT, we will be subject to federal income tax at regular corporate income tax rates. Even if we remain qualified for taxation as a REIT, we may be subject to some federal, state, local and foreign taxes on our income and property in addition to taxes owed with respect to our TRS operations. In particular, while state income tax regimes often parallel the federal income tax regime for REITs, many states do not completely follow federal rules and some do not follow them at all. The significant components of our deferred tax assets and deferred tax liabilities as of December 31, 2024 and 2023 are presented below: DECEMBER 31, 2024 2023 Deferred Tax Assets: Accrued liabilities and other adjustments $ 156,349 $ 100,476 Net operating loss carryforwards 168,773 158,363 Valuation allowance (132,714) (103,897) 192,408 154,942 Deferred Tax Liabilities: Other assets, principally due to differences in amortization (185,301) (220,218) Property, plant and equipment, principally due to differences in depreciation (63,192) (90,156) Other (122,844) (65,909) (371,337) (376,283) Net deferred tax (liability) asset $ (178,929) $ (221,341) The deferred tax assets and deferred tax liabilities as of December 31, 2024 and 2023 are presented below: DECEMBER 31, 2024 2023 Noncurrent deferred tax assets (Included in Other, a component of Other assets, net) $ 26,412 $ 14,069 Noncurrent deferred tax liabilities (205,341) (235,410) At December 31, 2024, we have federal net operating loss carryforwards of $95,543 and disallowed interest expense carryforwards of $152,156, both of which can be carried forward indefinitely, and of which $89,178 and $68,745, respectively, are expected to be realized to reduce future federal taxable income. We have assets for foreign net operating losses of $146,616 and foreign disallowed interest expense carryforwards of $17,746, with various expiration dates (and in some cases no expiration date), subject to valuation allowances of approximately 72.0% and 46.5%, respectively. If actual results differ unfavorably from certain of our estimates used, we may not be able to realize all or part of our net deferred income tax assets and additional valuation allowances may be required. Although we believe our estimates are reasonable, no assurance can be given that our estimates reflected in the tax provisions and accruals will equal our actual results. These differences could have a material impact on our income tax provision and operating results in the period in which such determination is made. A rollforward of the valuation allowance is as follows: YEAR ENDED DECEMBER 31, BALANCE AT BEGINNING OF CHARGED (CREDITED) TO OTHER INCREASES/(DECREASES) (1)(2) BALANCE 2024 $ 103,897 $ 37,018 $ (8,201) $ 132,714 2023 47,514 4,855 51,528 103,897 2022 51,744 (1,333) (2,897) 47,514 (1) Other decreases and increases in valuation allowances are primarily related to changes in foreign currency exchange rates and prior year acquisitions. (2) Prior to 2023, certain of our non-United States tax loss carryforwards were determined to have a remote possibility of realization and therefore were not reported in the table above. In connection with the implementation of the Organization for Economic Co-operation and Development (the "OECD") global minimum tax initiative known as Pillar Two, any existing deferred taxes not disclosed in our 2023 financial statements will not be available in the future to reduce tax otherwise due under Pillar Two. Accordingly, beginning in 2023, we are disclosing in the above table the tax effects of these non-United States tax loss carryforwards offset with a full valuation allowance. The components of net income (loss) before provision (benefit) for income taxes for the years ended December 31, 2024, 2023 and 2022 are as follows: YEAR ENDED DECEMBER 31, 2024 2023 2022 United States $ 56,617 $ 76,012 $ 449,241 Canada 153,450 111,331 103,826 Other Foreign 34,471 39,863 78,571 Net income (loss) before provision (benefit) for income taxes $ 244,538 $ 227,206 $ 631,638 The provision (benefit) for income taxes for the years ended December 31, 2024, 2023 and 2022 consist of the following components: YEAR ENDED DECEMBER 31, 2024 2023 2022 Federal—current $ 5,205 $ 1,255 $ 24,331 Federal—deferred (2,394) (18,488) (30,581) State—current 914 1,544 8,553 State—deferred (3,731) (4,630) (3,728) Foreign—current 96,168 72,408 92,525 Foreign—deferred (35,290) (12,146) (21,611) Provision (Benefit) for Income Taxes $ 60,872 $ 39,943 $ 69,489 A reconciliation of total income tax expense and the amount computed by applying the current federal statutory tax rate of 21.0% to net income (loss) before provision (benefit) for income taxes for the years ended December 31, 2024, 2023 and 2022, respectively, is as follows: YEAR ENDED DECEMBER 31, 2024 2023 2022 Computed "expected" tax provision $ 51,353 $ 47,713 $ 132,644 Changes in income taxes resulting from: Tax adjustment relating to REIT (33,926) (39,299) (82,620) State taxes, net of federal tax benefit (2,919) (3,147) 4,043 Increase (decrease) in valuation allowance 37,018 4,855 (1,333) Withholding taxes 11,359 11,658 10,600 (Reversal) reserve accrual and audit settlements, net of federal tax benefit (2,052) (4,946) 40 Change in valuation of acquisition contingencies 643 3,242 (19,656) Foreign tax rate differential 13,322 6,876 22,227 Adjustments relating to foreign taxes (10,346) 14,405 2,820 Excess tax benefits on equity compensation (5,047) (1,905) (955) Other, net 1,467 491 1,679 Provision (Benefit) for Income Taxes $ 60,872 $ 39,943 $ 69,489 Our effective tax rates for the years ended December 31, 2024, 2023 and 2022 were 24.9%, 17.6% and 11.0%, respectively. Our effective tax rate is subject to variability in the future due to, among other items: (i) changes in the mix of income between our QRSs and our TRSs, as well as among the jurisdictions in which we operate, (ii) tax law changes, (iii) volatility in foreign exchange gains and losses, (iv) the timing of the establishment and reversal of tax reserves, (v) our ability to utilize net operating losses and interest expenses that we generate and (vi) the taxability or deductibility of significant transactions. The primary reconciling items between the federal statutory tax rate of 21.0% and our overall effective tax rate were: YEAR ENDED DECEMBER 31, 2024 2023 2022 The lack of tax benefits recognized for the ordinary losses and disallowed interest expenses of certain entities of $37,018 and differences in the tax rates to which our foreign earnings are subject of $13,322, partially offset by the benefits derived from the dividends paid deduction of $33,926. In addition, we recorded gains and losses in Other expense (income), net during the period, for which there was no tax impact. The benefits derived from the dividends paid deduction of $39,299 and the differences in the tax rates to which our foreign earnings are subject of $6,876. In addition, there were gains and losses recorded in Other expense (income), net for which there was no tax impact. The benefits derived from the dividends paid deduction of $82,620 and the differences in the tax rates to which our foreign earnings are subject of $22,227. In addition, there were gains and losses recorded in Other expense (income), net and Gain (loss) on disposal/write-down of property, plant and equipment, net during the period for which there were insignificant tax impacts. As a REIT, we are entitled to a deduction for dividends paid, resulting in a substantial reduction of federal income tax expense. As a REIT, substantially all of our income tax expense will be incurred based on the earnings generated by our foreign subsidiaries and our domestic TRSs. We provide for foreign withholding taxes on the undistributed earnings of our foreign TRSs because it is not our intention to reinvest the undistributed earnings of our foreign TRSs indefinitely outside the United States. As a REIT, future repatriation of incremental undistributed earnings of our foreign subsidiaries will not be subject to federal or state income tax. The OECD has issued proposals that change long-standing tax principles, including a global minimum tax rate of 15% ("Pillar Two"). While the United States has not enacted legislation to effectuate Pillar Two, Iron Mountain operates in many foreign jurisdictions that have enacted legislation to implement Pillar Two. Pillar Two is applicable for Iron Mountain beginning in 2024. Since we do not have material operations in jurisdictions with tax rates lower than the Pillar Two minimum, we are not expecting a material impact on our effective tax rate, corporate tax liabilities or cash tax liabilities. We continue to monitor United States and global legislative actions as well as administrative guidance related to Pillar Two for potential impacts. The evaluation of an uncertain tax position is a two-step process. The first step is a recognition process whereby we determine whether it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The second step is a measurement process whereby a tax position that meets the more likely than not recognition threshold is calculated to determine the amount of benefit to recognize in the financial statements. The tax position is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. We have elected to recognize interest and penalties associated with uncertain tax positions as a component of the provision (benefit) for income taxes in the accompanying Consolidated Statements of Operations. We recorded decreases of $375 and $2,557 and an increase of $90 for gross interest and penalties for the years ended December 31, 2024, 2023 and 2022, respectively. We had $3,558 and $4,183 accrued for the payment of interest and penalties as of December 31, 2024 and 2023, respectively. A summary of tax years that remain subject to examination by major tax jurisdictions is as follows: TAX YEARS TAX JURISDICTION See Below United States—Federal and State 2021 to present United Kingdom 2016 to present Canada The normal statute of limitations for United States federal tax purposes is three years from the date the tax return is filed; however, the statute of limitations may remain open for periods longer than three years in instances where a federal tax examination is in progress. The 2024, 2023 and 2022 tax years and net operating loss carryforwards utilized in these years remain subject to examination for United States federal tax purposes. The normal statute of limitations for state purposes is between three to five years. However, certain of our state statute of limitations remain open for periods longer than this when audits are in progress. We are subject to income taxes in the United States and numerous foreign jurisdictions. We are subject to examination by various tax authorities in jurisdictions in which we have business operations or a taxable presence. We regularly assess the likelihood of additional assessments by tax authorities and provide for these matters as appropriate. As of December 31, 2024, we had $25,876 of reserves related to uncertain tax positions, of which $19,740 and $6,136 is included in other long-term liabilities and deferred income taxes, respectively, in the accompanying Consolidated Balance Sheet. As of December 31, 2023, we had $23,570 of reserves related to uncertain tax positions, of which $20,488 and $3,082 is included in other long-term liabilities and deferred income taxes, respectively, in the accompanying Consolidated Balance Sheet. Although we believe our tax estimates are appropriate, the final determination of tax audits and any related litigation could result in changes to our estimates. A rollforward of unrecognized tax benefits is as follows: Gross tax contingencies—January 1, 2022 $ 27,772 Gross additions based on tax positions related to the current year 2,271 Gross additions for tax positions of prior years 723 Gross reductions for tax positions of prior years (1,866) Acquired unrecognized tax benefits 1,354 Lapses of statutes (2,501) Gross tax contingencies—December 31, 2022 27,753 Gross additions based on tax positions related to the current year 3,511 Gross additions for tax positions of prior years 634 Gross reductions for tax positions of prior years (5,454) Lapses of statutes (2,874) Gross tax contingencies—December 31, 2023 23,570 Gross additions based on tax positions related to the current year 3,091 Gross reductions for tax positions of prior years (1,698) Acquired unrecognized tax benefits 5,717 Lapses of statutes (4,804) Gross tax contingencies—December 31, 2024 $ 25,876 The reversal of the reserves of $25,876 as of December 31, 2024 will be recorded as a reduction of our income tax provision, if sustained. We believe that it is reasonably possible that an amount up to $2,941 of our unrecognized tax positions may be recognized by the end of 2025 as a result of a lapse of statute of limitations or upon closing and settling significant audits in various worldwide jurisdictions.

Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	We maintain a robust information security program that is designed to protect our information and the information of our customers. Our information security program is based on a recognized cybersecurity framework established by the National Institute of Standards and Technology ("NIST") and establishes controls to mitigate critical areas of cybersecurity risk. Our information security program has adopted all elements of the NIST cybersecurity framework, including the six functions of identify, protect, detect, respond, recover and govern, as well as each of the categories and control groups thereunder. This does not imply that we meet any particular technical standards, specifications, or requirements, but only that we use the NIST framework as a guide to ensure our information security program is designed to manage cybersecurity risks relevant to our business. Among other things, the cybersecurity controls in our information security program address information access rights, incident monitoring and response processes, information technology system configuration, network security, security architecture planning, mobile device security and compliance with information security policy requirements and protocols. These cybersecurity controls are designed to oversee, identify and mitigate risks from all cybersecurity threats, including those arising from our use of third-party service providers. Our cybersecurity controls are evaluated regularly by our internal information security team, and we engage a third party examiner to assess the maturity of our information security program against the NIST cybersecurity framework no less frequently than bi-annually. Additionally, our information security program is assessed periodically by a federal regulator in the United States as part of its routine audit of the Company. In addition to our internal assessments, we also assess our third-party service providers on a regular basis using a risk-based approach that assigns a risk calculation to each such service provider. The results of our assessments are tracked and evaluated to ensure these third parties comply with our cybersecurity standards. We require all employees to undertake data protection and cybersecurity training and compliance programs annually. Our reputation for providing secure information storage to customers is critical to the success of our business, and protecting against material cybersecurity risks is an integral part of maintaining that reputation. A successful cybersecurity breach could lead to theft or misuse of our or our customers’ proprietary or confidential information or our employees’ personal information and result in third-party claims against us, regulatory penalties and reputational harm. As part of our information security program, we also actively monitor emerging cyberattack patterns to develop custom detection capabilities and mitigation techniques to protect against material risk of cybersecurity threats. Upon encountering a cybersecurity incident, our information security team responds using our detailed cybersecurity incident response plan ("CSIRP"), which is based on industry best practices, relevant legal requirements and our contractual commitments. Among other things, the CSIRP sets forth the specific criteria used to assess a cybersecurity incident, mitigate risks of adverse consequences associated with any such incident, protocols to escalate the management of the incident and the process to inform our executive management team and any impacted functions of our business. All cybersecurity incidents are assessed to determine whether disclosure is required pursuant to any contractual or regulatory requirements and any material cybersecurity incident is also reported to our board of directors (our "Board"). To date, our information security program has been successful in protecting against risks from cybersecurity threats, and we have not had any cybersecurity incidents that have materially affected or are reasonably likely to materially affect our business strategy, results of operations or financial condition. Additional information about cybersecurity risks we face is discussed in Item 1A of Part I, “Risk Factors,” under the heading “Attacks on our internal IT systems could damage our reputation, cause us to lose revenues, and adversely affect our business, financial condition and results of operations”, which should be read in conjunction with the information above.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2024
Accounting Policies [Abstract]
Principles of Consolidation	The accompanying financial statements reflect our financial position, results of operations, comprehensive income (loss), (deficit) equity and cash flows on a consolidated basis. The accompanying financial statements include the results of those entities over which we have a controlling financial interest or of which we are deemed to be the primary beneficiary. All intercompany transactions and account balances have been eliminated.
Use of Estimates	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the 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.
Changes in Presentation	Certain items previously reported under specific captions within the statement of cash flows and Note 10 have been reclassified to conform to the current year presentation.
Foreign Currency	Local currencies are the functional currencies for our operations outside the United States, with the exception of certain foreign holding companies, whose functional currency is the United States dollar. In those instances where the local currency is the functional currency, assets and liabilities are translated at period-end exchange rates, and revenues and expenses are translated at average exchange rates for the applicable period.
Cash and Cash Equivalents	Cash and cash equivalents include cash on hand and cash invested in highly liquid short-term securities, which have remaining maturities at the date of purchase of less than 90 days. Cash and cash equivalents are carried at cost, which approximates fair value.
Allowance for Doubtful Accounts and Credit Memo Reserves	We maintain an allowance for doubtful accounts and a credit memo reserve for estimated losses resulting from the potential inability of our customers to make required payments and potential disputes regarding billing and service issues. We evaluate and monitor the collectability of accounts receivable based on a combination of factors, including historical loss experience, assessments of trends in our aged receivables and credit memo activity, the location of our businesses, the composition of our customer base, our product and service lines, potential future macroeconomic factors, including natural disasters, and reasonable and supportable forecasts for expected future collectability of our outstanding receivables. Continued adjustments will be made, as it becomes evident, should there be any material change to reasonable and supportable forecasts that may impact our likelihood of collection. Our highly diverse global customer base, with no single customer accounting for more than approximately 1% of revenue during the years ended December 31, 2024, 2023 and 2022, limits our exposure to concentration of credit risk. Additionally, we write off uncollectible balances as circumstances warrant, generally no later than one year past due.
Concentrations of Credit Risk	Financial instruments that potentially subject us to credit risk consist principally of cash and cash equivalents (including money market funds and time deposits) and accounts receivable.As per our risk management investment policy, we limit exposure to concentration of credit risk by limiting the amount invested in any one mutual fund to a maximum of 1% of the fund's total assets or in any one financial institution to a maximum of $75,000.
Property, Plant and Equipment	Property, plant and equipment are stated at cost and depreciated using the straight-line method with the following useful lives (in years): DESCRIPTION RANGE Buildings, building improvements and data center infrastructure 5 to 40 Leasehold improvements 5 to 20 or life of the lease (whichever is shorter) Racking structures 1 to 20 or life of the lease (whichever is shorter) Warehouse equipment/vehicles 1 to 10 Furniture and fixtures 1 to 10 Computer hardware and software 2 to 7 Minor maintenance costs are expensed as incurred. Major improvements which (i) extend the life, (ii) increase the capacity or functionality or (iii) improve the safety or the efficiency of property owned are capitalized and depreciated. Major improvements to leased buildings are capitalized as leasehold improvements and depreciated. CAPITALIZED INTEREST
Internal Use Software	We develop various software applications for internal use. Computer software costs associated with internal use software are expensed as incurred until certain capitalization criteria are met. Third party consulting costs, as well as payroll and related costs for employees directly associated with, and devoting time to, the development of internal use computer software projects (to the extent time is spent directly on the project) are capitalized. Capitalization of costs, including costs incurred for upgrades and enhancements that provide additional functionality to our existing software, generally begins during the application development stage of the project, which occurs after it is probable that the project will be completed and used to perform the function intended. Capitalization ends when the asset is ready for its intended use. Capitalized internal use software costs are depreciated on a straight-line basis over the expected useful life of the software, commencing when the software is ready for its intended use. Computer software costs that are capitalized are periodically evaluated for impairment.
Asset Retirement Obligation	Entities are required to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. Asset retirement obligations represent the costs to replace or remove tangible long-lived assets required by law, regulatory rule or contractual agreement. Our asset retirement obligations are primarily the result of requirements under our facility lease agreements which generally have "return to original condition" clauses which would require us to remove or restore items such as shred pits, vaults, demising walls and office build-outs, among others. The significant assumptions used in estimating our aggregate asset retirement obligations are the timing of removals, the probability of a requirement to perform, estimated cost and associated expected inflation rates that are consistent with historical rates and credit-adjusted risk-free rates that approximate our incremental borrowing rate.
Leases	We lease facilities for certain warehouses, data centers and office spaces. We also have land leases, including those on which certain facilities are located. The majority of our leased facilities are classified as operating leases that, on average, have initial lease terms of five one one We account for all leases, both operating and financing, in accordance with Accounting Standards Codification ("ASC") Topic 842, Leases ("ASC 842"). Our accounting policy provides that leases with an initial term of 12 months or less will not be included within the lease right-of-use assets and lease liabilities recognized on our Consolidated Balance Sheets. We recognize the lease payments for those leases with an initial term of 12 months or less in our Consolidated Statements of Operations on a straight-line basis over the lease term. The lease right-of-use assets and related lease liabilities are classified as either operating or financing. Lease right-of-use assets are calculated as the net present value of future payments plus any capitalized initial direct costs less any tenant improvements or lease incentives. Lease liabilities are calculated as the net present value of future payments. In calculating the present value of the lease payments, we utilize the rate stated in the lease (in the limited circumstances when such rate is explicitly stated) or, if no rate is explicitly stated, we utilize a rate that reflects our securitized incremental borrowing rate by geography for the lease term. We account for nonlease components (which include common area maintenance, taxes, and insurance) with the related lease component. Any variable nonlease components are not included within the lease right-of-use asset and lease liability on our Consolidated Balance Sheets, and instead, are reflected as an expense in the period incurred.
Long-Lived Assets	We review long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be recoverable. Recoverability of these assets is determined by comparing the sum of the forecasted undiscounted net cash flows of the operation to which the assets relate to their carrying amount. The operations are generally distinguished by the business segment and geographic region in which they operate. If it is determined that we are unable to recover the carrying amount of the assets, the long-lived assets are written down, on a pro rata basis, to fair value. Fair value is determined based on discounted cash flows or appraised values, depending upon the nature of the assets. Long-lived assets, including finite-lived intangible assets, are amortized over their useful lives. Annually, or more frequently if events or circumstances warrant, we assess whether a change in the lives over which long-lived assets, including finite-lived intangible assets, are amortized is necessary.
Goodwill and Other Indefinite- Lived Intangible Assets	GOODWILL AND OTHER INDEFINITE-LIVED INTANGIBLE ASSETS Goodwill and intangible assets with indefinite lives are not amortized but are reviewed annually for impairment, or more frequently if impairment indicators arise. Other than goodwill, we currently have no intangible assets that have indefinite lives and which are not amortized. We test goodwill annually on October 1, and more frequently if impairment indicators arise that would require an interim test. We have performed our annual goodwill impairment review as of October 1, 2024, 2023 and 2022. We concluded that as of October 1, 2024, 2023 and 2022, goodwill was not impaired. REPORTING UNITS AS OF OCTOBER 1, 2023 Our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2023 were as follows: • North America Records and Information Management ("North America RIM") • Europe Records and Information Management ("Europe RIM") • Middle East, North Africa, South Africa and Turkey Information Management ("MENATSA RIM") • Latin America Records and Information Management ("Latin America RIM") • Asia Pacific Records and Information Management ("APAC RIM") • Entertainment Services • Global Data Center • Fine Arts • ALM There were no changes to the composition of our reporting units between October 1, 2023 and December 31, 2023. GOODWILL BY REPORTING UNIT AS OF DECEMBER 31, 2023 The carrying value of goodwill, net for each of our reporting units described above as of December 31, 2023 is as follows: SEGMENT REPORTING UNIT CARRYING VALUE AS OF DECEMBER 31, 2023 Global RIM Business North America RIM $ 2,694,093 Europe RIM 541,860 MENATSA RIM 26,502 Latin America RIM 120,119 APAC RIM 496,944 Entertainment Services 32,427 Global Data Center Business Global Data Center 478,930 Corporate and Other Fine Arts 47,535 ALM 579,502 Total $ 5,017,912 2024 REPORTING UNIT CHANGES During 2024, as a result of the realignment of our global managerial structure, we reassessed the composition of our reporting units. The realignment of our global managerial structure did not change the composition of our reportable segments (as described and defined in Note 11). As a result of the reassessment, our businesses that were previously managed under our former MENATSA RIM reporting unit are now managed as part of our "Europe RIM" reporting unit. Additionally, our former Entertainment Services reporting unit is now referred to as "Media and Archive Services" to more accurately reflect the offerings of this business. There were no changes to our other reporting units. REPORTING UNITS AS OF OCTOBER 1, 2024 Our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2024 were as follows: • North America RIM • Europe RIM • Latin America RIM • APAC RIM • Media and Archive Services • Global Data Center • Fine Arts • ALM There were no changes to the composition of our reporting units between October 1, 2024 and December 31, 2024. The fair value of our reporting units has generally been determined using a combined approach based on the present value of future cash flows (the "Discounted Cash Flow Model") and market multiples (the "Market Approach"). The Discounted Cash Flow Model incorporates significant assumptions including future revenue growth rates, operating margins, discount rates and capital expenditures. The Market Approach requires us to make assumptions related to Adjusted EBITDA (as defined in Note 11) multiples. Changes in economic and operating conditions impacting these assumptions or changes in multiples could result in goodwill impairments in future periods. In conjunction with our annual goodwill impairment reviews, we reconcile the sum of the valuations of all of our reporting units to our market capitalization as of such dates.
Finite-Lived Intangible Assets and Liabilities	I. CUSTOMER AND SUPPLIER RELATIONSHIP INTANGIBLE ASSETS Customer and supplier relationship intangible assets, which are acquired through either business combinations or acquisitions of customer relationships, are generally amortized over periods ranging from 10 to 30 years. Customer and supplier relationship intangible assets are recorded based upon estimates of their fair value. Finite-lived intangible assets associated with our Global Data Center Business consist of the following: DATA CENTER IN-PLACE LEASE INTANGIBLE ASSETS AND DATA CENTER TENANT RELATIONSHIP INTANGIBLE ASSETS Data center in-place lease intangible assets ("Data Center In-Place Leases") and data center tenant relationship intangible assets ("Data Center Tenant Relationships") reflect the value associated with acquiring a data center operation with active tenants as of the date of acquisition. The value of Data Center In-Place Leases is determined based upon an estimate of the economic costs (such as lost revenues, tenant improvement costs, commissions, legal expenses and other costs to acquire new data center leases) avoided by acquiring a data center operation with active tenants. Data Center In-Place Leases are amortized over the weighted average remaining term of the acquired data center leases. The value of Data Center Tenant Relationships is determined based upon an estimate of the economic costs avoided upon lease renewal of the acquired tenants, based upon expectations of lease renewal. Data Center Tenant Relationships are amortized over the weighted average remaining anticipated life of the relationship with the acquired tenant. DATA CENTER ABOVE-MARKET AND BELOW-MARKET IN-PLACE LEASE INTANGIBLE ASSETS Data center above-market in-place lease intangible assets ("Data Center Above-Market Leases") and data center below-market in-place lease intangible assets ("Data Center Below-Market Leases") are recorded at the net present value of the difference between (i) the contractual amounts to be paid pursuant to each in-place lease and (ii) management’s estimate of the fair market lease rates for each corresponding in-place lease. Data Center Above-Market Leases and Data Center Below-Market Leases are amortized over the remaining non-cancellable term of the acquired in-place lease to storage revenue.
Deferred Financing Costs	Deferred financing costs are amortized over the life of the related debt. If debt is retired early, the related unamortized deferred financing costs are written off in the period the debt is retired and included as a component of Other expense (income), net.
Derivatives Instruments and Hedging Activities	Derivative instruments are measured at fair value and are recorded as either assets or liabilities in our Consolidated Balance Sheets. Periodically, we acquire derivative instruments that are intended to hedge either cash flows or values that are subject to foreign exchange or other market price risk and not for trading purposes. We have formally documented our hedging relationships, including identification of the hedging instruments and the hedged items, as well as our risk management objectives and strategies for undertaking each hedge transaction concurrently with the execution of the derivative instrument. Given the recurring nature of our revenues and the long-term nature of our asset base, we have the ability and the preference to use long-term, fixed interest rate debt to finance our business, thereby preserving our long-term returns on invested capital. We may use interest rate swaps as a tool to maintain our targeted level of fixed rate debt. In addition, we may enter into cross-currency swaps to hedge the variability of exchange rates between the United States dollar and the currencies of our foreign subsidiaries, as well as interest rates. We may also use borrowings in foreign currencies, either obtained in the United States or by our foreign subsidiaries, to hedge foreign currency risk associated with our international investments. Gains and losses realized as a result of the maturing or termination of our interest rate swaps and cross-currency swaps are reflected as operating cash flows within our Consolidated Statements of Cash Flows.
Fair Value Measurements	Entities are permitted under GAAP to elect to measure certain financial instruments and certain other items at either fair value or cost. We have elected the cost measurement option in all circumstances where we had an option. Our financial assets or liabilities that are carried at fair value are required to be measured using inputs from the three levels of the fair value hierarchy. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The three levels of the fair value hierarchy are as follows: Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access at the measurement date. Level 2—Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.), and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).
Noncontrolling Interests	Unaffiliated third parties own noncontrolling interests in certain of our consolidated subsidiaries. The classification of these ownership interests are evaluated under ASC 810, Consolidation and ASC 480, Distinguishing Liabilities from Equity . Ownership interests are classified as equity unless the underlying agreements contain provisions requiring classification as a liability or temporary equity. Noncontrolling interests are presented as a separate component of Iron Mountain's Stockholders’ (Deficit) Equity in the accompanying Consolidated Balance Sheets and Consolidated Statements of (Deficit) Equity. Certain agreements with our noncontrolling interest shareholders contain put options which allow the noncontrolling interest shareholders to require us to purchase their respective interests in such subsidiaries at certain times and at purchase prices as stipulated in the underlying agreements (generally at fair value). These ownership interests, otherwise known as redeemable noncontrolling interests, are classified as temporary equity in our Consolidated Balance Sheets and Consolidated Statements of (Deficit) Equity. Redeemable noncontrolling interests are reported as temporary equity at the greater of their redemption value or the noncontrolling interest holders’ proportionate share of the underlying subsidiary’s net carrying value. Increases or decreases in the redemption value are offset against Additional Paid-in Capital. Changes in ownership interests that do not result in a loss of control are accounted for as equity transactions. If control is lost, the subsidiary’s assets, liabilities and noncontrolling interests are derecognized, and any resulting gain or loss is recorded in earnings. The amount of consolidated net income attributable to noncontrolling interests, including redeemable noncontrolling interests, are presented in the accompanying Consolidated Statements of Operations and Consolidated Statements of Comprehensive Income (Loss). When ownership interests are determined to be mandatorily redeemable, they are classified as liabilities and included as a component of Accrued expenses and other current liabilities or Other long-term liabilities on our Consolidated Balance Sheets, depending on the timing of the obligation.
Revenues	Payments that are made to a customer in order to terminate the customer’s storage of records with its current records management vendor ("Permanent Withdrawal Fees"), or direct payments to a customer for which no distinct benefit is received in return, are collectively referred to as "Customer Inducements". Customer Inducements are treated as a reduction of the transaction price over the associated contract terms, which range from one Our revenues consist of storage rental revenues and service revenues and are reflected net of sales and value-added taxes. Storage rental revenues, which are considered a key driver of financial performance for the storage and information management services industry, consist primarily of recurring periodic rental charges related to the storage of materials or data (generally on a per unit basis) that are typically retained by customers for many years and of revenues associated with our data center operations. Service revenues include charges for related service activities, the most significant of which include: (1) the handling of records, including the addition of new records, temporary removal of records from storage, refiling of removed records, customer termination and permanent withdrawal fees, project revenues and courier operations consisting primarily of the pickup and delivery of records upon customer request; (2) secure shredding of sensitive documents and the subsequent sale of shredded paper for recycling, the price of which can fluctuate from period to period; (3) the decommissioning, data erasure, processing and disposition, and recycling or sale of information technology ("IT") hardware and component assets; (4) digital solutions, including the scanning, imaging and document conversion services of active and inactive records, consulting services and the sale of software as a service; and (5) data center services, including set up, monitoring and support of our customers' assets which are protected in our data center facilities, and special project services, including data center fitout. We account for our revenue in accordance with ASC 606, Revenue from Contracts with Customers ("ASC 606"), with the exception of our data center storage revenue, as described below. Customers are generally billed monthly based on contractually agreed-upon terms, and storage rental and service revenues are recognized in the month the respective storage rental or service is provided, in line with the transfer of control to the customer. When storage rental fees or services are billed in advance, amounts related to future storage rental or prepaid service contracts are accounted for as deferred revenue and recognized upon the transfer of control to the customer, generally ratably over the contract term. Customer contracts generally include promises to provide monthly recurring storage and related services that are essentially the same over time and have the same pattern of transfer of control to the customer; therefore, most performance obligations represent a promise to deliver a series of distinct services over time (as determined for purposes of ASC 606, a "series"). For those contracts that qualify as a series, we apply the "right to invoice" practical expedient as we have a right to consideration from the customer in an amount that corresponds directly with the value of the underlying performance obligation transferred to the customer to date. Additionally, each purchasing decision is fully in the control of the customer; therefore, consideration beyond the current reporting period is variable and allocated to the specific period to which the consideration relates, which is consistent with the practical expedient. Revenue from product sales, the significant majority of which are shred paper and IT asset sales, is recognized at the point in time at which control transfers to the customer, which is generally upon shipment. Our Global Data Center Business features storage rental provided to the customer at contractually specified rates over a fixed contractual period. The revenue related to the storage component of our Global Data Center Business is recognized on a straight-line basis over the contract term in accordance with ASC 842. The revenue related to the service component of our Global Data Center Business is recognized in the period the related services are provided. From time to time, we make payments to entities that are also customers under a revenue contract. These payments are primarily comprised of (i) Customer Inducements and (ii) payments to customers of our ALM business under revenue sharing arrangements for the remarketing of the customer's disposed IT assets. Customer Inducements do not represent payments for a distinct service, and, as such, are treated as a reduction of the transaction price over periods ranging from one Certain costs to fulfill or obtain customer contracts and certain initial direct costs of obtaining data center leases, including the costs associated with the initial movement of customer records into physical storage and certain commission expenses, are collectively referred to as "Contract Costs". The following describes our significant Contract Costs: INTAKE COSTS (AND ASSOCIATED DEFERRED REVENUE) The costs of the initial intake of customer records into physical storage ("Intake Costs") are deferred and amortized as a component of depreciation and amortization in our Consolidated Statements of Operations generally over three years, consistent with the transfer of the performance obligation to the customer to which the asset relates. In instances where such Intake Costs are billed to the customer, the associated revenue is deferred and recognized over the same three-year period. COMMISSIONS Certain commission payments that are directly associated with obtaining long-term contracts are capitalized and amortized as a component of depreciation and amortization in our Consolidated Statements of Operations generally over three years, consistent with the transfer of the performance obligation to the customer to which the asset relates. We also apply the practical expedient to expense certain commission payments as incurred when the amortization period for those commission payments is one year or less. DATA CENTER LESSOR CONSIDERATIONS Our Global Data Center Business features storage rental provided to customers at contractually specified rates over a fixed contractual period. Our data center revenue contracts are accounted for in accordance with ASC 842. ASC 842 provides a practical expedient which allows lessors to account for nonlease components with the related lease component if both the timing and pattern of transfer are the same for nonlease components and the lease component, and the lease component, if accounted for separately, would be classified as an operating lease. The single combined component is accounted for under ASC 842 if the lease component is the predominant component and is accounted for under ASC 606 if the nonlease components are the predominant components. We have elected to take this practical expedient. Our data center revenue contracts may contain Consumer Price Index rent escalation clauses. Consumer Price Index rent escalation clauses are considered variable lease payments and are recognized as income in the period earned.
Stock-Based Compensation	We record stock-based compensation expense, utilizing the straight-line method, for the cost of stock options, restricted stock units ("RSUs"), and performance units ("PUs") (together, "Employee Stock-Based Awards"). Forfeitures are recorded in the period during which they occur. Our non-employee directors are considered employees for purposes of our Employee Stock-Based Awards and the associated reporting of these awards. Our equity compensation plans generally provide that, upon a vesting change in control (as defined in each plan), any unvested options and other awards granted thereunder shall vest immediately if an employee is terminated as a result of the change in control or terminates their own employment for good reason (as defined in each plan). Other than in specified circumstances, no equity-based award will vest before the first anniversary of the date of grant. On January 20, 2015, our stockholders approved the adoption of the Iron Mountain Incorporated 2014 Stock and Cash Incentive Plan, as amended (the "2014 Plan"). The 2014 Plan permits us to continue to grant awards through May 12, 2031. A total of 20,750,000 shares of common stock have been reserved for grants of options and other rights under our various stock incentive plans, including the 2014 Plan. The number of shares available for grant under our various stock incentive plans at December 31, 2024 was 4,984,132. RETIREMENT ELIGIBLE CRITERIA Our Employee Stock-Based Awards include the following retirement provision: • Upon an employee’s retirement on or after attaining age 55 with at least five years of service, if the sum of (i) the award recipient’s age at retirement and (ii) the award recipient’s years of service with us totals at least 65, the award recipient is entitled to continued vesting of any outstanding Employee Stock-Based Awards, provided that their retirement occurs on or after a minimum of six months from the grant date (the "Retirement Criteria"). • Accordingly, (i) grants of Employee Stock-Based Awards to an employee who has met the Retirement Criteria on or before the date of grant, or will meet the Retirement Criteria before the six month anniversary in the year of the grant, will be expensed over six months from the date of grant and (ii) grants of Employee Stock-Based Awards to employees who will meet the Retirement Criteria during the award’s normal vesting period will be expensed between the date of grant and the date upon which the award recipient meets the Retirement Criteria. • Stock options and RSUs granted to award recipients who meet the Retirement Criteria will be delivered to the award recipient based upon the original vesting schedule. If an award recipient retires and has met the Retirement Criteria, stock options will remain exercisable until the original expiration date of the stock options. PUs granted to award recipients who meet the Retirement Criteria will be delivered in accordance with the original vesting schedule of the applicable PU award and remain subject to the same performance conditions. STOCK OPTIONS Options are generally granted with exercise prices equal to the market price of the stock on the date of grant; however, in certain instances, options are granted at exercise prices greater than the market price of the stock on the date of grant. We issue options that become exercisable ratably over a period of three years from the date of grant and have a contractual life of 10 years from the date of grant, unless the holder’s employment is terminated sooner. Dividends and dividend equivalents are not paid with respect to stock options. Expected volatility is calculated utilizing daily historical volatility over a period that equates to the expected life of the option. (2) Risk-free interest rate is based on the United States Treasury interest rates whose term is consistent with the expected life (estimated period of time outstanding) of the stock options. (3) Expected dividend yield is considered in the option pricing model and represents our annualized expected per share dividends over the trade price of our common stock at the date of grant. (4) Expected life of the stock options granted is estimated using the historical exercise behavior of employees. Our RSUs generally have a vesting period of three years from the date of grant. However, RSUs granted to our non-employee directors vest immediately upon grant. All RSUs accrue dividend equivalents associated with the underlying stock as we declare dividends. Dividends will generally be paid to holders of RSUs in cash upon the vesting date of the associated RSU and will be forfeited if the RSU does not vest. The fair value of RSUs is the excess of the market price of our common stock at the date of grant over the holder's purchase price (which is typically zero). The PUs we issue vest based on our performance against predefined operational performance and relative total shareholder return based targets over a three-year performance period. The vesting is subject to a minimum level of return on invested capital in the third year of the performance period, and the number of PUs earned is based on certain metrics determined at the outset of the performance period. The number of PUs earned is based on: • either (i) the revenue performance for each year averaged at the end of the three-year performance period, or (ii) if (a) absolute Company total shareholder return is positive at the end of the three-year performance period and (b) a predetermined revenue hurdle is achieved in the third year of the performance period, then the revenue performance achieved in the third year of the performance period; and • the total return on our common stock relative to the companies comprising the Morgan Stanley Capital International ("MSCI") United States REIT Index. The number of PUs earned will range from 0% to approximately 350% of the initial award. All of our PUs will be settled in shares of our common stock and are subject to cliff vesting three years from the date of the original PU grant. As detailed above, PUs granted are subject to the Retirement Criteria. PUs are generally expensed over the three-year performance period, unless they are granted to a recipient who meets the Retirement Criteria, for which expense will be recognized as described above. PUs granted to recipients who meet the Retirement Criteria will continue to vest and be delivered in accordance with the original vesting schedule of the applicable PU award and remain subject to the same performance conditions. All PUs accrue dividend equivalents associated with the underlying stock as we declare dividends. Dividends will generally be paid to holders of PUs in cash upon the settlement date of the associated PU and will be forfeited if the PU does not vest.
Acquisition and Integration Costs	ACQUISITION AND INTEGRATION COSTSAcquisition and integration costs represent operating expenditures directly associated with the closing and integration activities of our business acquisitions that have closed, or are highly probable of closing, and include (i) advisory, legal and professional fees to complete business acquisitions and (ii) costs to integrate acquired businesses into our existing operations, including move, severance and system integration costs (collectively, "Acquisition and Integration Costs"). We account for acquisitions using the acquisition method of accounting, and, accordingly, the assets and liabilities acquired are recorded at their estimated fair values and the results of operations for each acquisition have been included in our consolidated results from their respective acquisition dates. Allocations of the purchase price for acquisitions are based on estimates of the fair value of the net assets acquired and are subject to adjustment upon the finalization of the purchase price allocations. The accounting for business combinations requires estimates and judgments regarding expectations for future cash flows of the acquired business, and the allocations of those cash flows to identifiable tangible and intangible assets, in determining the assets acquired and liabilities assumed. The fair values assigned to tangible and intangible assets acquired and liabilities assumed, including contingent consideration, are based on management’s best estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary valuation procedures and techniques. The estimates and assumptions underlying the initial valuations are subject to the collection of information necessary to complete the valuations within the measurement periods, which are up to one year from the respective acquisition dates.
Income Taxes	Accounting for income taxes requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the tax and financial reporting bases of assets and liabilities and for loss and credit carryforwards. Valuation allowances are provided when recovery of deferred tax assets does not meet the more likely than not standard as defined in GAAP. We have elected to recognize interest and penalties associated with uncertain tax positions as a component of the Provision (benefit) for income taxes in the accompanying Consolidated Statements of Operations. We have been organized and have operated as a REIT effective beginning with our taxable year that ended on December 31, 2014. As a REIT, we are generally permitted to deduct from our federal taxable income the dividends we pay to our stockholders. The income represented by such dividends is not subject to federal taxation at the entity level but is taxed, if at all, at the stockholder level. The income of our domestic TRSs, which hold our domestic operations that may not be REIT-compliant as currently operated and structured, is subject, as applicable, to federal and state corporate income tax. In addition, we and our subsidiaries continue to be subject to foreign income taxes in other jurisdictions in which we have business operations or a taxable presence, regardless of whether assets are held or operations are conducted through subsidiaries disregarded for federal income tax purposes or TRSs. We will also be subject to a separate corporate income tax on any gains recognized on the sale or disposition of any asset previously owned by a C corporation during a five-year period after the date we first owned the asset as a REIT asset that are attributable to "built-in gains" with respect to that asset on that date. We will also be subject to a built-in gains tax on our depreciation recapture recognized into income as a result of accounting method changes in connection with our acquisition activities. If we fail to remain qualified for taxation as a REIT, we will be subject to federal income tax at regular corporate income tax rates. Even if we remain qualified for taxation as a REIT, we may be subject to some federal, state, local and foreign taxes on our income and property in addition to taxes owed with respect to our TRS operations. In particular, while state income tax regimes often parallel the federal income tax regime for REITs, many states do not completely follow federal rules and some do not follow them at all. As a REIT, we are entitled to a deduction for dividends paid, resulting in a substantial reduction of federal income tax expense. As a REIT, substantially all of our income tax expense will be incurred based on the earnings generated by our foreign subsidiaries and our domestic TRSs. We provide for foreign withholding taxes on the undistributed earnings of our foreign TRSs because it is not our intention to reinvest the undistributed earnings of our foreign TRSs indefinitely outside the United States. As a REIT, future repatriation of incremental undistributed earnings of our foreign subsidiaries will not be subject to federal or state income tax. The OECD has issued proposals that change long-standing tax principles, including a global minimum tax rate of 15% ("Pillar Two"). While the United States has not enacted legislation to effectuate Pillar Two, Iron Mountain operates in many foreign jurisdictions that have enacted legislation to implement Pillar Two. Pillar Two is applicable for Iron Mountain beginning in 2024. Since we do not have material operations in jurisdictions with tax rates lower than the Pillar Two minimum, we are not expecting a material impact on our effective tax rate, corporate tax liabilities or cash tax liabilities. We continue to monitor United States and global legislative actions as well as administrative guidance related to Pillar Two for potential impacts. The evaluation of an uncertain tax position is a two-step process. The first step is a recognition process whereby we determine whether it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The second step is a measurement process whereby a tax position that meets the more likely than not recognition threshold is calculated to determine the amount of benefit to recognize in the financial statements. The tax position is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement.
Income (Loss) Per Share-Basic and Diluted	Basic income (loss) per common share is calculated by dividing income (loss) by the weighted average number of common shares outstanding. The calculation of diluted income (loss) per share is consistent with that of basic income (loss) per share but gives effect to all potential common shares (that is, securities such as stock options, RSUs, PUs, warrants or convertible securities) that were outstanding during the period, unless the effect is antidilutive.
New Accounting Pronouncements	RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2023-07, Improvements to Reportable Segments Disclosures ("ASU 2023-07") to provide more detail in the disclosures for reportable segments. The main provisions of ASU 2023-07 requires (i) enhanced disclosures about significant segment expenses, (ii) extension of certain annual disclosures to interim periods and (iii) certain qualitative information on the chief operating decision maker. We adopted ASU 2023-07 on January 1, 2024 on a retrospective basis. The required disclosures are included in Note 11. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848) ("ASU 2020-04"). ASU 2020-04 provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions, for a limited period of time, to ease the potential burden of recognizing the effects of reference rate reform on financial reporting. The amendments in ASU 2020-04 apply to contracts, hedging relationships and other transactions that reference the London Inter-Bank Offered Rate ("LIBOR") or another reference rate expected to be discontinued due to the global transition away from LIBOR and certain other interbank offered rates. Under ASU 2020-04, an entity could elect to apply the amendments beginning March 12, 2020 through December 31, 2022. In December 2022, the FASB issued ASU No. 2022-06, Reference Rate Reform (Topic 848), Deferral of the Sunset Date of Topic 848 ("ASU 2022-06") to defer the sunset date of Topic 848 from December 31, 2022 to December 31, 2024, after which entities will no longer be permitted to apply the relief in Topic 848. We adopted the guidance in these updates on January 1, 2024, and there was no material impact on our consolidated financial statements. OTHER AS YET ADOPTED ACCOUNTING PRONOUNCEMENTS In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosures ("ASU 2023-09") to provide disaggregated income tax disclosures on the rate reconciliation and income taxes paid. Further, certain requirements related to uncertain tax positions and unrecognized deferred tax liabilities are eliminated. The amendments in this update should be applied on a prospective basis, with retrospective application permitted. ASU 2023-09 will be effective for us on January 1, 2025, with early adoption permitted. We do not expect ASU 2023-09 to have a material impact on our consolidated financial statements. In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40 ), Disaggregation of Income Statement Expenses
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. A portion of the defense and/or settlement costs associated with such litigation is covered by various commercial liability insurance policies purchased by us and, in limited cases, indemnification from third parties. Our policy is to establish reserves for loss contingencies when the losses are both probable and reasonably estimable. We record legal costs associated with loss contingencies as expenses in the period in which they are incurred.
