Safe Harbor Statement Under the Private Securities Litigation Reform Act of 1995: Safe Harbor Statement Under the Private Securities Litigation Reform Act of 1995: This release contains certain forward- looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and other securities laws and is subject to the safe-harbor created by such Act. Forward-looking statements include, but are not, limited to, our financial performance outlook and statements concerning our operations, economic performance, financial condition, goals, beliefs, future growth strategies, investment objectives, plans and current expectations, such as 2019 guidance, and statements about our investments, cost saving initiatives, the value added from recent data center deals and other goals. These forward-looking statements are subject to various known and unknown risks, uncertainties and other factors. When we use words such as "believes," "expects," "anticipates," "estimates" 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 to remain qualified for taxation as a real estate investment trust for U.S. federal income tax purposes; (ii) the adoption of alternative technologies and shifts by our customers to storage of data through non-paper based technologies; (iii) changes in customer preferences and demand for our storage and information management services; (iv) the cost to comply with current and future laws, regulations and customer demands relating to data security and privacy issues, as well as fire and safety standards; (v) the impact of litigation or disputes that may arise in connection with incidents in which we fail to protect our customers' information or our internal records or IT systems and the impact of such incidents on our reputation and ability to compete; (vi) changes in the price for our storage and information management services relative to the cost of providing such storage and information management services; (vii) changes in the political and economic environments in the countries in which our international subsidiaries operate and changes in the global political climate; (viii) our ability or inability to manage growth, expand internationally, complete acquisitions on satisfactory terms, to close pending acquisitions and to integrate acquired companies efficiently; (ix) changes in the amount of our growth and recurring capital expenditures and our ability to invest according to plan; (x) our ability to comply with our existing debt obligations and restrictions in our debt instruments or to obtain additional financing to meet our working capital needs; (xi) the impact of service interruptions or equipment damage and the cost of power on our data center operations; (xii) changes in the cost of our debt; (xiii) the impact of alternative, more attractive investments on dividends; (xiv) the cost or potential liabilities associated with real estate necessary for our business; (xv) the performance of business partners upon whom we depend for technical assistance or management expertise; (xvi) other trends in competitive or economic conditions affecting our financial condition or results of operations not presently contemplated; and (xvii) other risks described more fully in our filings with the Securities and Exchange Commission, including under the caption “Risk Factors” in our periodic reports or incorporated therein. You should not rely upon forward-looking statements except as statements of our present intentions and of our present expectations, which may or may not occur. Except as required by law, we undertake no obligation to release publicly the result of any revision to these forward-looking statements that may be made to reflect events or circumstances after the date hereof or to reflect the occurrence of unanticipated events. Reconciliation of Non-GAAP Measures: Throughout this presentation, Iron Mountain will discuss (1) Adjusted EBITDA, (2) Adjusted Earnings per Share (“Adjusted EPS”), (3) Funds from Operations (“FFO Nareit”), (4) FFO (Normalized) and (5) Adjusted Funds from Operations (“AFFO”). 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, income (loss) from continuing operations, net income (loss) attributable to Iron Mountain Incorporated or cash flows from operating activities from continuing operations (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 document (see Table of Contents). Iron Mountain does not provide a reconciliation of non-GAAP measures that it discusses as part of its annual guidance or long term outlook because certain significant information required for such reconciliation is not available without unreasonable efforts or at all, including, most notably, the impact of exchange rates on Iron Mountain’s transactions, loss or gain related to the disposition property, plant and equipment (including of real estate) and other income or expense. Without this information, Iron Mountain does not believe that a reconciliation would be meaningful.

Section X - Appendix and Definitions Non-GAAP Measures and Definitions Non-GAAP measures are supplemental metrics designed to enhance our disclosures and to provide additional information that we believe to be important for investors to consider when evaluating our financial performance. These non-GAAP measures should be considered in addition to, but not as a substitute for, other measures of financial performance reported in accordance with accounting principles generally accepted in the United States of America (“GAAP”), such as operating income, income (loss) from continuing operations, net income (loss) or cash flows from operating activities from continuing operations (as determined in accordance with GAAP). Adjusted Earnings Per Share, or Adjusted EPS Adjusted EPS is defined as reported earnings per share fully diluted from continuing operations excluding: (i) (gain) loss on disposal/write-down of property, plant and equipment (including real estate), net; (ii) intangible impairments; (iii) other (income) expense, net (which includes foreign currency transaction (gains) losses, net); (iv) Significant Acquisition Costs; and (v) the tax impact of reconciling items and discrete tax items. Adjusted EPS includes income (loss) attributable to noncontrolling interests. 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. Adjusted EBITDA and Adjusted EBITDA Margin Adjusted EBITDA is defined as income (loss) from continuing operations before interest expense, net, provision (benefit) for income taxes, depreciation and amortization, and also excludes certain items that we believe are not indicative of our core operating results, specifically: (i) (gain) loss on disposal/write-down of property, plant and equipment (including real estate), net; (ii) intangible impairments; (iii) other (income) expense, net (which includes foreign currency transaction (gains) losses, net); and (iv) Significant Acquisition Costs. 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 flow 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. Adjusted EBITDA excludes both interest expense, net and the provision (benefit) for income taxes. These expenses are associated with our capitalization and tax structures, which we do not consider when evaluating the operating profitability of our core operations. Finally, Adjusted EBITDA does not include depreciation and amortization expenses, in order to eliminate the impact of capital investments, which we evaluate by comparing capital expenditures to incremental revenue generated and as a percentage of total revenues. Adjusted EBITDA and Adjusted EBITDA Margin should be considered in addition to, but not as a substitute for, other measures of financial performance reported in accordance with GAAP, such as operating income, income (loss) from continuing operations, net income (loss) or cash flows from operating activities from continuing operations (as determined in accordance with GAAP). Adjusted Funds From Operations, or AFFO AFFO is defined as FFO (Normalized) excluding non-cash rent expense or income plus depreciation on non-real estate assets, amortization expense associated with customer relationship value (CRV), intake costs, acquisitions of customer relationships and other intangibles, and excluding amortization expense associated with capitalized internal commissions, amortization of deferred financing costs, revenue reduction associated with amortization of permanent withdrawal fees and above-and below-market data center leases, stock-based compensation expense and the impact of reconciling to normalized cash taxes, less recurring capital expenditures and non-real estate growth investments (on a cash basis), excluding Significant Acquisition Capital Expenditures. We believe AFFO is a useful measure in determining our ability to generate excess cash that may be used for reinvestment in the business, discretionary deployment in investments such as real estate or acquisition opportunities, returning capital to our stockholders and voluntary prepayments of indebtedness. Additionally AFFO is reconciled to cash flow from operations to adjust for real estate and REIT tax adjustments, Significant Acquisition Costs and other non-cash expenses. AFFO does not include adjustments for customer inducements, acquisition of customer relationships and investment in innovation as we consider these expenditures to be growth related. Adjusted Gross Profit Adjusted Gross Profit is defined as Operating Income (loss) excluding: (i) depreciation and amortization; (ii) (gain) loss on disposal/write-down of property plant and equipment, net; (iii) intangible impairments; (iv) selling, general and administrative expenses; and (v) Significant Acquisition Costs within cost of sales. Funds From Operations, or FFO (Nareit), and FFO (Normalized) Funds from operations (“FFO”) is defined by the National Association of Real Estate Investment Trusts ("Nareit") and us as net income (loss) excluding depreciation on real estate assets, gains on sale of real estate, net of tax and amortization of data center leased-based intangibles ("FFO (Nareit)"). 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). Although Nareit has published a definition of FFO, modifications to FFO (Nareit) are common among REITs as companies seek to provide financial measures that most meaningfully reflect their particular business. 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) (gain) loss on disposal/write-down of property, plant and equipment (including real estate), net; (ii) intangible impairments; (iii) other expense (income), net (which includes foreign currency transaction (gains) losses, net); (iv) real estate financing lease depreciation; (v) Significant Acquisition Costs; (vi) the tax impact of reconciling items and discrete tax items; (vii) loss (income) from discontinued operations, net of tax; and (viii) loss (gain) on sale of discontinued operations, net of tax. FFO (Normalized) per share FFO (Normalized) divided by weighted average fully-diluted shares outstanding. investors.ironmountain.com 29
