• Total reported revenues for the first quarter were $1.6 billion, compared with $1.5 billion in the first quarter of 2024, an  increase of 7.8%. Excluding the impact of foreign currency exchange ("Fx"), total reported revenues increased 9.4%  compared to the prior year, driven by an 8.8% increase in storage rental revenue and a 10.2% increase in service  revenue.  • Net Income for the first quarter was $16.2 million, compared with $77.0 million in the first quarter of 2024, primarily  driven by the impact of changes in the exchange rates on our intercompany balances.  • Adjusted EBITDA for the first quarter was $579.9 million, compared with $518.9 million in the first quarter of 2024, an  increase of 11.8%. On a constant currency basis, Adjusted EBITDA increased by 13.5% in the first quarter, compared  to the first quarter of 2024, driven by increased revenue in our Global RIM, ALM, and Data Center businesses and  improved operating leverage coming from our continued improvement activities. • FFO (Normalized) per share was $0.77 for the first quarter, compared with $0.74 in the first quarter of 2024.  • AFFO was $348.4 million for the first quarter, compared with $323.7 million in the first quarter of 2024, an increase of  7.6% driven by improved Adjusted EBITDA.  • AFFO per share was $1.17 for the first quarter, compared with $1.10 in the first quarter of 2024.  Dividend On May 1, 2025, Iron Mountain's Board of Directors declared a quarterly cash dividend of $0.785 per share of common  stock for the second quarter. The second quarter 2025 dividend is payable on July 3, 2025, to shareholders of record at  the close of business on June 16, 2025.

Without this  information, Iron Mountain does not believe that a reconciliation would be meaningful.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           2

Forward Looking Statements We have made statements in this press release that constitute "forward-looking statements" as that term is defined in the  Private Securities Litigation Reform Act of 1995 and other securities laws. These forward-looking statements concern our  current expectations regarding our future results from operations, economic performance, financial condition, goals,  strategies, investment objectives, plans and achievements.  These forward-looking statements are subject to various known and unknown risks, uncertainties and other factors, and  you should not rely upon them except as statements of our present intentions and of our present expectations, which may  or may not occur. When we use words such as “believes”, “expects”, “anticipates”, “estimates”, “plans”, “intends”,  “projects”, “pursue”, “will” or similar expressions, we are making forward-looking statements. Although we believe that our  forward-looking statements are based on reasonable assumptions, our expected results may not be achieved, and actual  results may differ materially from our expectations. In addition, important factors that could cause actual results to differ  from expectations include, among others: (i) our ability or inability to execute our strategic growth plan, including our  ability to invest according to plan, grow our businesses (including through joint ventures or other co-investment vehicles),  incorporate alternative technologies (including artificial intelligence) into our offerings, achieve satisfactory returns on new  product offerings, continue our revenue management, expand and manage our global operations, complete acquisitions  on satisfactory terms, integrate acquired companies efficiently and transition to more sustainable sources of energy; (ii)  changes in customer preferences and demand for our storage and information management services, including as a  result of the shift from paper and tape storage to alternative technologies that require less physical space or services  activity; (iii) the costs of complying with and our ability to comply with laws, regulations and customer requirements,  including those relating to data privacy and cybersecurity issues, as well as fire and safety and environmental standards;  (iv) the impact of attacks on our internal information technology (“IT”) systems, including the impact of such incidents on  our reputation and ability to compete and any litigation or disputes that may arise in connection with such incidents; (v)  our ability to fund capital expenditures; (vi) the impact of our distribution requirements on our ability to execute our  business plan; (vii) our ability to remain qualified for taxation as a real estate investment trust for United States federal  income tax purposes; (viii) changes in the political and economic environments in the countries in which we operate and  changes in the global political climate; (ix) our ability to raise debt or equity capital and changes in the cost of our debt; (x)  our ability to comply with our existing debt obligations and restrictions in our debt instruments; (xi) the impact of service  interruptions or equipment damage and the cost of power on our data center operations; (xii) the cost or potential  liabilities associated with real estate necessary for our business; (xiii) unexpected events, including those resulting from  climate change or geopolitical events, could disrupt our operations and adversely affect our reputation and results of  operations; (xiv) failures to implement and manage new IT systems; (xv) other trends in competitive or economic  conditions affecting our financial condition or results of operations not presently contemplated; and (xvi) the other risks  described in our periodic reports filed with the SEC, including under the caption “Risk Factors” in Part I, Item 1A of our  Annual Report. Except as required by law, we undertake no obligation to update any forward-looking statements  appearing in this press release.  Reconciliation of Non-GAAP Measures Throughout this press release, Iron Mountain discusses (1) Adjusted EBITDA, (2) Adjusted EPS, (3) FFO (Nareit), (4)  FFO (Normalized), (5) AFFO and (6) AFFO per share. These measures do not conform to accounting principles generally  accepted in the United States (“GAAP”). These non-GAAP measures are supplemental metrics designed to enhance our  disclosure and to provide additional information that we believe to be important for investors to consider in addition to, but  not as a substitute for, other measures of financial performance reported in accordance with GAAP, such as operating  income, net income (loss) attributable to Iron Mountain Incorporated or cash flows from operating activities (as  determined in accordance with GAAP). The reconciliation of these measures to the appropriate GAAP measure, as  required by Regulation G under the Securities Exchange Act of 1934, as amended, and their definitions are included later  in this release.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           4

Adjusted EBITDA Margin is calculated by dividing Adjusted EBITDA by total revenues. We use multiples of current or projected  Adjusted EBITDA in conjunction with our discounted cash flow models to determine our estimated overall enterprise valuation and to evaluate  acquisition targets. We believe Adjusted EBITDA and Adjusted EBITDA Margin provide our current and potential investors with relevant and useful  information regarding our ability to generate cash flows to support business investment. These measures are an integral part of the internal reporting  system we use to assess and evaluate the operating performance of our business.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          7

Our  structural tax rate for purposes of the calculation of Adjusted EPS for the quarters ended March 31, 2025 and 2024 was 17.0% and 13.9% respectively,  and quarter ended December 31, 2024 was 15.6%. Adjusted Earnings Per Share, or Adjusted EPS We define Adjusted EPS as reported earnings per share fully diluted from net income (loss) attributable to Iron Mountain Incorporated (inclusive of our  share of adjusted losses (gains) from our unconsolidated joint ventures) and excluding certain items, specifically: (i) Acquisition and Integration Costs;  (ii) Restructuring and other transformation; (iii) Loss (gain) on disposal/write-down of property, plant and equipment, net (including real estate); (iv) Other  expense (income), net; (v) Stock-based compensation expense; (vi) Non-cash amortization related to derivative instruments; (vii) Tax impact of  reconciling items and discrete tax items; and (viii) Amortization related to the write-off of certain customer relationship intangible assets. We do not  believe these excluded items to be indicative of our ongoing operating results, and they are not considered when we are forecasting our future results.  We believe Adjusted EPS is of value to our current and potential investors when comparing our results from past, present and future periods. Figures  may not foot due to rounding. The Tax Impact of reconciling Items and discrete tax Items is calculated using the current quarter’s estimate of the annual  structural tax rate. This may result in the current period adjustment plus prior reported quarterly adjustments not summing to the full year adjustment.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          8

(2) Includes amortization expense for Data Center In-Place Lease Intangible Assets and Data Center Tenant Relationship Intangible Assets. (3) Represents the tax impact of (i) the reconciling items above, which impact our reported net income (loss) before provision (benefit) for income taxes  but have an insignificant impact on our reported provision (benefit) from income taxes and (ii) other discrete tax items. Funds From Operations, or FFO (Nareit), and FFO (Normalized) Funds from operations ("FFO") is defined by the National Association of Real Estate Investment Trusts as net income (loss) excluding depreciation on  real estate assets, losses and gains on sale of real estate, net of tax, and amortization of data center leased-based intangibles (“FFO (Nareit)”). We  calculate our FFO measure, including FFO (Nareit), adjusting for our share of reconciling items from our unconsolidated joint ventures. FFO (Nareit)  does not give effect to real estate depreciation because these amounts are computed, under GAAP, to allocate the cost of a property over its useful life.  Because values for well-maintained real estate assets have historically increased or decreased based upon prevailing market conditions, we believe  that FFO (Nareit) provides investors with a clearer view of our operating performance. Our most directly comparable GAAP measure to FFO (Nareit) is  net income (loss). We modify FFO (Nareit), as is common among REITs seeking to provide financial measures that most meaningfully reflect their particular business  ("FFO (Normalized)"). Our definition of FFO (Normalized) excludes certain items included in FFO (Nareit) that we believe are not indicative of our core  operating results, specifically: (i) Acquisition and Integration Costs; (ii) Restructuring and other transformation; (iii) Loss (gain) on disposal/write-down of  property, plant and equipment, net (excluding real estate); (iv) Other expense (income) net; (v) Stock-based compensation expense; (vi) Non-cash  amortization related to derivative instruments; (vii) Real estate financing lease depreciation; (viii) Tax impact of reconciling items and discrete tax items;  (ix) Intangible impairments; and (x) (Income) loss from discontinued operations, net of tax. FFO (Normalized) per share FFO (Normalized) divided by weighted average fully-diluted shares outstanding.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          9

Adjusted Funds From Operations, or AFFO  We define adjusted funds from operations (“AFFO”) as FFO (Normalized) (1) excluding (i) Non-cash rent expense (income), (ii) Depreciation on non-real  estate assets, (iii) Amortization expense associated with customer and supplier relationship value, intake costs, acquisitions of customer and supplier  relationships, capitalized commissions and other intangibles, (iv) Amortization of deferred financing costs and debt discount/premium, (v) Revenue  reduction associated with amortization of customer inducements and above- and below-market data center leases and (vi) The impact of reconciling to  normalized cash taxes and (2) including Recurring capital expenditures. We also adjust for these items to the extent attributable to our portion of  unconsolidated ventures. We believe that AFFO, as a widely recognized measure of operations of REITs, is helpful to investors as a meaningful  supplemental comparative performance measure to other REITs, including on a per share basis. AFFO should be considered in addition to, but not as a  substitute for, other measures of financial performance reported in accordance with GAAP, such as operating income, net income (loss) or cash flows  from operating activities (as determined in accordance with GAAP).  AFFO per share AFFO divided by weighted average fully-diluted shares outstanding.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          10
