Iron Mountain Third Quarter 2014 Financial Results � Strong Third Quarter Operating Performance Driven by Continued Volume Gains and Solid Constant Dollar Storage Rental Growth � � Significant Progress Toward Strategic Goals, Including Acquisition Activity and Real Estate Purchases � � 2015 Preliminary Guidance in Line with Strategic Plan � Total reported revenues for the quarter were $783 million, compared with $755 million in 2013, while year-to-date total reported revenues were $2.34 billion, compared with $2.26 billion in 2013. On a constant dollar (C$) basis, total revenue growth for the quarter was 3.9%, reflecting solid storage rental revenue gains of 5.6% and service revenue growth of 1.3%. Year-to-date C$�total revenue growth was 4.3%, driven by storage rental revenue gains of 5.5% and service revenue growth of 2.6%. Adjusted OIBDA for the quarter was $235 million, compared with $240 million in 2013, while year-to-date Adjusted OIBDA was $706 million, compared with $700 million in 2013. Adjusted OIBDA for the quarter includes ongoing Real Estate Investment Trust (REIT) compliance costs and acquisition-related costs. Year-to-date Adjusted OIBDA includes $3.5 million of costs associated with the company�s 2013 restructuring and approximately $8 million of REIT compliance costs, while Adjusted OIBDA for the first nine months of 2013 included $5 million in restructuring charges. Adjusted EPS for the quarter was $0.35 per diluted share, compared with $0.43 per diluted share in 2013, while year-to-date Adjusted EPS was $1.10 per diluted share, compared with $1.19 per diluted share in 2013. Adjusted EPS for both the quarter and nine months ended September 30, 2013 has been restated to reflect a structural tax rate of approximately 15% and includes the impacts to Adjusted OIBDA noted above. GAAP EPS for the third quarter of 2014 was $0.00 per share, primarily due to changes in estimates resulting in a $26.4 million net tax provision related to the company�s conversion to a REIT effective January 1, 2014 and a $13.2 million tax provision related to foreign repatriation. Year-to-date GAAP EPS of $1.62 per share includes the net tax benefit recognized in the second quarter, primarily related to the reversal of current and deferred tax assets and liabilities, partially offset by incremental taxes related to foreign repatriation. GAAP EPS for the third quarter and year to date in 2013 includes $44 million of charges related to the early extinguishment of debt, which reduced 2013 GAAP EPS by $0.15 per share, net of the related tax benefit.

Earnings Commentary 5

Earnings Commentary 6 Financial Review Consolidated Adjusted OIBDA margins for the third quarter of 2014 of 30.1% were down from 31.8% in the third quarter of 2013, reflecting the REIT compliance and acquisition related charges noted earlier. Third quarter Adjusted OIBDA margins in the North American RIM segment remained strong at 39.5%, while North American DM Adjusted OIBDA margins of 56.2% were down compared with the same period in 2013, which included a higher level of one-time project revenue. The International business continued to deliver profitability on a portfolio basis in line with the company�s mid-20% target, with Adjusted OIBDA margins of 23.6% for the third quarter. Capital expenditures for the first nine months of 2014, excluding $74 million of real estate and $4 million of REIT-related capital expenditures, totaled $150 million, or 6.4% of revenues. The company�s liquidity position remains strong with availability of $1.2 billion under its revolving credit facility and a net total lease adjusted leverage ratio of 5.2x at quarter end, as compared to a maximum allowable ratio of 6.5x. The calculation for this ratio is net debt including the capitalized value of lease obligations divided by EBITDAR as defined in the company�s credit agreement. 2014 Outlook and 2015 Preliminary Guidance On November 4, 2014, the company will issue $560 million of common stock in connection with its $700 million Special Distribution; the shares issued will impact weighted average shares outstanding from the date of issuance. Using the average of the common stock closing prices on October 27, 28 and 29, 2014 of $35.55, the company will issue approximately 15.8 million new shares, increasing shares outstanding to approximately 209 million shares and full-year weighted average shares to 196 million. As a result of this stock distribution and the impact of foreign currency exchange rates, the company will reduce Adjusted EPS for 2014 to $1.33 to $1.44 from the company�s current range of $1.37 to $1.52. FFO (Normalized) per share will be reduced to $2.21 to $2.46 from the current range of $2.25 to $2.51. For 2015, the company expects Total Reported Revenues and Adjusted OIBDA to be generally in line with its strategic plan prior to the anticipated impact of foreign currency. Adjusted EPS, FFO (NAREIT) per share, and FFO (Normalized) per share are expected to grow in line with growth in Adjusted OIBDA, or roughly 1% to 5% on a C$�basis, prior to the impact of shares issued in connection with the Special Distribution. Detailed guidance is provided on page 10.

Company Profile Iron Mountain is a global leader in enterprise storage with a high- return, real estate-based, business model, yielding revenues over $3 billion per annum. The company provides storage and information management services to a high-quality, diversified customer base across numerous industries and government organizations. Iron Mountain serves over 155,000 customers, including more than 95% of the Fortune 1000, and no single customer accounts for as much as 2% of revenues. Iron Mountain provides storage and information management services in 36 countries on five continents, storing over 500 million cubic feet of records in a portfolio of over 1,000 facilities containing more than 67 million square feet of space. The company employs over 19,500 people. Iron Mountain's financial model is based on the recurring nature of its storage rental revenues and the resulting storage net operating income (NOI). Supported by its consistent, predictable storage rental revenues, which have increased for 25 consecutive years, the company generates predictable, low volatility growth in key metrics such as storage NOI and AFFO. This fundamental financial characteristic provides stability through economic cycles. Iron Mountain has the opportunity to invest capital at attractive returns both domestically and internationally. There remains a large un-vended opportunity that can support sustained storage volumes in developed markets such as North America and high growth opportunities in emerging markets that are just beginning to outsource their storage of physical documents.

Service Business Detail 23 (1) Includes Document Management Services, Consulting, Intellectual Property Management, Fulfillment Services, Data Center Services and Entertainment Services Our service revenue growth has been negatively impacted by declining activity rates as stored records are becoming less active. The amount of information available to customers through the Internet or their own information systems has been steadily increasing in recent years. As a result, while customers continue to store their records with us, they are less likely than they have been in the past to retrieve records, thereby reducing service activity levels. While we expect this trend to continue through 2014, the rate of decline in service activity has begun to moderate in recent periods.

Appendix 29 Non-GAAP Measures 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 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 Unites States of America (�GAAP�), such as operating or 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 from continuing operations excluding: (1) (gain) loss on the disposal/write-down of property, plant and equipment, net; (2) intangible impairments; (3) other (income) expense, net; (4) REIT Costs; and (5) the tax impact of reconciling items and discrete tax items. 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 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 (including amortization of deferred financing costs) and non-cash equity compensation expense, less maintenance 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 of capital to our stockholders and voluntary prepayments of indebtedness. Adjusted Operating Income Before Depreciation, Amortization, Intangible Impairments, and REIT Costs, or Adjusted OIBDA Adjusted OIBDA is defined as operating income before depreciation, amortization, intangible impairments, (gain) loss on disposal/write-down of property, plant and equipment, net, and REIT Costs. These measures are an integral part of the internal reporting system we use to assess and evaluate the operating performance of our business. We use multiples of current or projected Adjusted OIBDA in conjunction with our discounted cash flow models to determine our overall enterprise valuation and to evaluate acquisition targets. We believe Adjusted OIBDA provides our current and potential investors with relevant and useful information regarding our ability to generate cash flow to support business investment.

Appendix Non-GAAP Measures (continued) Funds From Operations, or FFO (NAREIT), and FFO (Normalized) FFO is a non-GAAP financial measure commonly used in the REIT industry. FFO is defined by the National Association of Real Estate Investment Trusts (�NAREIT�) and us as net income excluding gains and losses on the sale or write-down of real estate assets plus depreciation on real estate assets. FFO does not give effect to real estate depreciation and amortization 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 (Normalized) provides investors with a clearer view of our operating performance. Our most directly comparable GAAP measure to FFO (Normalized) is net income attributable to Iron Mountain. Although NAREIT has published a definition of FFO, modifications to the NAREIT calculation of FFO are common among REITs as companies seek to provide financial measures that most meaningfully reflect their business. Our definition of FFO (Normalized) excludes other items that we believe do not appropriately reflect our underlying operations such as intangible impairment charges, other income and expense (including foreign exchange gains and losses), income and losses from discontinued operations, provision or benefit from deferred taxes and REIT Costs. Service Adjusted OIBDA Service Adjusted OIBDA is calculated by taking service revenues excluding terminations and permanent withdrawals less direct expenses and allocated overhead tied to the service business. Terminations and permanent withdrawals are excluded from this calculations as they are included in the Storage NOI calculation. Service Adjusted OIBDAR Service Adjusted OIBDA as defined above, excluding rent expense associated with the service business. Storage Net Operating Income, or Storage NOI Storage NOI is defined as revenue from rental activities (storage rental revenue, termination fees and permanent withdrawal fees) less storage rental costs. Storage rental costs include facility costs (excluding rent), storage rental labor, other storage costs and allocated overhead. 30

Our Asia Pacific operations provide Records Management, Data Protection & Recovery, Destruction and DMS throughout Australia, with Records Management and Data Protection & Recovery services also provided in certain cities in India, Singapore, Hong Kong-SAR and China. Corporate and Other � Consists of our data center business in the United States, the primary product offering of our Emerging Businesses segment, as well as costs related to executive and staff functions, including finance, human resources and information technology, which benefit the enterprise as a whole. These costs are primarily related to the general management of these functions on a corporate level and the design and development of programs, policies and procedures that are then implemented in the individual segments, with each segment bearing its own cost of implementation. Corporate and Other also includes non-cash equity compensation expense associated with all employee stock-based awards. 31

Appendix 32 Definitions (continued) Capacity Measures Building Capacity � The maximum number of cubic feet of records or standard DPUs that can be stored in a given facility. Building Capacity Utilization � The number of cubic feet of records or standard DPUs in storage divided by the Building Capacity. Installed Racking Capacity � The storage capacity of the racking installed in a given facility. Capacity is generally measured in cubic feet or standard DPUs. Installed Racking Capacity Utilization � The number of cubic feet of records or standard DPUs in storage divided by the Installed Racking Capacity. Capital Expenditures � Our business requires capital expenditures to support our expected storage rental revenue and service revenue growth and ongoing operations, new products and services and increased profitability. The majority of our capital goes to support business line growth and our ongoing operations. Additionally, we invest capital to acquire or construct real estate. We also expend capital to support the development and improvement of products and services and projects designed to increase our profitability. These expenditures are generally relatively small and discretionary in nature. We categorize our capital expenditures as follows: Maintenance � These capital expenditures include major repairs to and/or the replacement of existing assets. These expenditures are associated with either Real Estate Assets (as described above) or Non-Real Estate Assets (all other capital assets). Non-Real Estate Assets are primarily associated with our service operations. Other � Other includes all other capital expenditures not classified as Real Estate or Maintenance capital expenditures. Components of Overhead Allocated Overhead � Includes overhead expenses directly associated with storage and service business operations allocated as follows: Field Operation Costs � Allocated to storage and service operations based on percent of revenue. Bad Debt Expenses � Allocated to storage and service operations based on percent of revenue. Transportation Costs � Allocated fully to service operations.

Appendix 33 Definitions (continued) Components of Overhead (continued) Corporate Overhead � Includes all other overhead expenses associated with business support functions, including: Executive, Legal, Real Estate/Facilities, Accounting, Financial Performance & Analysis, Treasury, Tax, Internal Audit, M&A, Security, Procurement, HR, REIT, Other G&A, Integration Costs, IT, Product Engineering and Product Management. Customer Turnover Overhead � Overhead associated with customer acquisition and retention including Sales, Marketing and Account Management expenses. Constant Dollar Growth (C$) � The year-over-year growth rate excluding the impact of changes to foreign currency exchange rates. Constant currency growth rates are calculated by translating the 2013 results at the 2014 constant dollar budget rates. Destruction Rate � Calculated by dividing the total number of cubic feet of records removed from inventory due to destructions in a one-year period divided by the total number of cubic feet of records in storage at the beginning of the period. DPUs � Data protection units, a unit of measurement specific to our Data Protection storage services. Internal Revenue Growth � Internal revenue growth represents the year-over-year growth rate of revenues excluding the impacts of changes to foreign currency exchange rates, acquisitions and other unusual items. In general, only acquisitions that have been in our results for the full calendar year prior to the quarter of measurement are included in internal revenue growth. Lease Adjusted Leverage Ratio � The calculation for this ratio is EBITDA plus rent expense divided by net debt including the capitalized value of lease obligations. Net Volume Growth � New Records Management storage volume from existing customers, plus volume from new customers and volume from acquisitions, offset by volume related to destructions, permanent withdrawals and customer terminations. Quarterly percentages are calculated by dividing the trailing four quarters� total activity by the ending balance of the same prior-year period. Non-Cash Rent Expense � Calculated as rent expense less cash paid for rent. Permanent Withdrawal Rate � Calculated by dividing the total number of cubic feet of records removed from inventory due to permanent withdrawals in a one-year period divided by the total number of cubic feet of records in storage at the beginning of the period. Permanent withdrawals occur when records are permanently removed from inventory by customers for reasons other than the customer terminating its relationship.

Appendix 34 Definitions (continued) REIT Costs � Includes costs associated with our 2011 proxy contest, the previous work of the former Strategic Review Special Committee of the board of directors and costs associated with the Company�s conversion to a REIT, excluding REIT compliance costs beginning January 1, 2014 which we expect to recur in future periods. Regional NOI / CF or DPU � The average expected NOI for a specific region (NA, Europe, Latin America, Asia Pac) and product (Records Management or Data Protection). Stabilized Storage NOI � The projected Storage NOI of a facility once the facility has attained 85% capacity utilization. Tangible Assets � Includes PP&E, cash and cash equivalents, restricted cash, accounts receivable, deferred income taxes, and prepaid expenses. Volume Retention Rate � One minus the result of dividing the total number of cubic feet of records removed from inventory due to customer terminations in a one-year period by the total number of cubic feet of records in storage at the beginning of the period.
