(Unaudited)

(1) General

The interim condensed consolidated financial statements are presented herein and, in the opinion of management, reflect all adjustments of a normal recurring nature necessary for a fair presentation. Interim results are not necessarily indicative of results for a full year. Iron Mountain Incorporated, a Delaware corporation ("IMI"), and its subsidiaries ("we" or "us") provide storage of physical records and data backup media, information management solutions and enterprise-class colocation and wholesale data center space that help organizations in various locations throughout North America, Europe, Latin America, Asia and Africa. We offer comprehensive records and information management services and data management services, along with the expertise and experience to address complex storage and information management challenges such as rising storage rental costs, legal and regulatory compliance and disaster recovery requirements. We provide secure and reliable data center facilities to protect digital information and ensure the continued operation of our customers’ information technology infrastructure, with flexible deployment options, including both colocation and wholesale space.

The unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the United States Securities and Exchange Commission (the "SEC"). Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been omitted pursuant to those rules and regulations, but we believe that the disclosures included herein are adequate to make the information presented not misleading. The Condensed Consolidated Financial Statements and Notes thereto, which are included herein, should be read in conjunction with the Consolidated Financial Statements and Notes thereto for the year ended December 31, 2018 included in our Annual Report on Form 10-K filed with the SEC on February 14, 2019 (our "Annual Report").

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.

On January 10, 2018, we completed the acquisition of IO Data Centers, LLC ("IODC") (the "IODC Transaction"). See Note 3.

On January 1, 2019, we adopted Accounting Standards Update ("ASU") No. 2016-02, Leases (Topic 842), as amended ("ASU 2016-02"). See Note 2.d.

(2) Summary of Significant Accounting Policies

This Note 2 to Notes to Condensed Consolidated Financial Statements provides information and disclosure regarding certain of our significant accounting policies and should be read in conjunction with Note 2 to Notes to Consolidated Financial Statements included in our Annual Report, which may provide additional information with regard to the accounting policies set forth herein and other of our significant accounting policies.

a. Cash, Cash Equivalents and Restricted Cash

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.

At March 31, 2019 and December 31, 2018, we had approximately $15,250 and $15,141, respectively, of restricted cash held by certain financial institutions related to bank guarantees.

Goodwill

Since December 31, 2018, there have been no changes to our accounting polices related to the accounting for goodwill. As of March 31, 2019 and December 31, 2018, no factors were identified that would alter our October 1, 2018 goodwill impairment analysis.

Our reporting units as of December 31, 2018 are described in detail in Note 2.h. to Notes to Consolidated Financial Statements included in our Annual Report. On March 19, 2019, we divested the business included in our former Consumer Storage reporting unit, which had no goodwill associated with it at December 31, 2018 or at the date of the divestment. See Note 9 for additional information.

The goodwill associated with acquisitions completed during the first three months of 2019 (which are described in Note 3) has been incorporated into our reporting units as they existed as of December 31, 2018.

The changes in the carrying value of goodwill attributable to each reportable operating segment for the three months ended March 31, 2019 are as follows:

Data Center Lessor Considerations

Our data center business features storage rental provided to customers at contractually specified rates over a fixed contractual period. Prior to January 1, 2019, our data center revenue contracts were accounted for in accordance with Accounting Standards Codification (“ASC”) No. 840, Leases ("ASC 840"). On January 1, 2019, we adopted ASU 2016-02, as described in more detail in Note 2.d. Beginning on January 1, 2019, our data center revenue contracts will be accounted for in accordance with ASU 2016-02. ASU 2016-02 provides a practical expedient which allows lessors to account for nonlease components (such as power and connectivity, in the case of our data center business) 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 would be classified as an operating lease. The single combined component is accounted for under ASU 2016-02 if the lease component is the predominant component and is accounted for under ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"), if the nonlease components are the predominant components. We have elected to take this practical expedient. Storage rental revenue associated with our data center business was $59,718 for the three months ended March 31, 2019, which includes approximately $9,100 of revenue associated with power and connectivity. The revenue related to the service component of our data center business remains unchanged from the adoption of ASU 2016-02 and is recognized in the period the related services are provided. Our accounting treatment for data center revenue was not significantly impacted by the adoption of ASU 2016-02.

d. Leases

We lease facilities for certain warehouses, data centers and office space. 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 to 10 years, with one or more lease renewal options to extend the lease term. Our lease renewal option terms generally range from one to five years. The exercise of the lease renewal option is at our sole discretion and may contain fixed rent, fair market value based rent or Consumer Price Index rent escalation clauses. We include option periods in the lease term when our failure to renew the lease would result in an economic disincentive, thereby making it reasonably certain that we will renew the lease. We recognize straight line rental expense over the life of the lease and any fair market value or Consumer Price Index rent escalations are recognized as variable lease expense in the period in which the obligation is incurred. In addition, we lease certain vehicles and equipment. Vehicle and equipment leases have lease terms ranging from one to seven years.

In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-02, Leases (Topic 842) which requires lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases, both operating and financing (formerly referred to as capital leases under ASC 840). ASU 2016-02 requires certain qualitative and quantitative disclosures designed to give financial statement users information on the amount, timing, and uncertainty of cash flows arising from leases.

(2) Summary of Significant Accounting Policies (Continued)

We adopted ASU 2016-02 on January 1, 2019 on a modified retrospective basis under which we recognized and measured leases existing at, or entered into after, the beginning of the period of adoption. Therefore, we applied ASC 840 to all earlier comparative periods (prior to the adoption of ASU 2016-02), including disclosures, and recognized the effects of applying ASU 2016-02 as a cumulative-effect adjustment to retained earnings as of January 1, 2019, the effective date of the standard. As such, the comparative Condensed Consolidated Balance Sheet as of December 31, 2018 has not been restated to reflect the adoption of ASU 2016-02. Accordingly, the majority of the amount presented as deferred rent liabilities on our Consolidated Balance Sheet as of December 31, 2018 is now included in the calculation of operating lease right-of-use assets and any remaining amounts are now classified within other liability line items on our Condensed Consolidated Balance Sheet as of March 31, 2019. The transition guidance associated with ASU 2016-02 also permitted certain practical expedients. We elected the "package of 3" practical expedients permitted under the transition guidance which, among other things, allowed us to carryforward our historical lease classifications. We also adopted an accounting policy which 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 Condensed Consolidated Balance Sheets after the adoption of ASU 2016-02. We will continue to recognize the lease payments for those leases with an initial term of 12 months or less in the 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 will utilize the rate stated within the lease (in the limited circumstances when such rate is available) or, if no rate is explicitly stated, we have elected to utilize a rate that reflects our securitized incremental borrowing rate by geography for the lease term. In July 2018, the FASB issued ASU 2018-11, Leases - Targeted Improvements ("ASU 2018-11"). ASU 2018-11 provides a practical expedient which allows lessees to 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 the Condensed Consolidated Balance Sheets, and instead, are reflected as an expense in the period incurred. We have elected to take this practical expedient upon adoption of ASU 2016-02.

At January 1, 2019, we recognized the cumulative effect of initially applying ASU 2016-02 as an adjustment to the opening balance of (distributions in excess of earnings) earnings in excess of distributions, resulting in an increase of approximately $5,800 to stockholders' equity due to certain build to suit leases that were accounted for as financing leases under ASC 840, Leases, but are accounted for as operating leases under ASU 2016-02 at January 1, 2019.

e. Stock-Based Compensation

We record stock-based compensation expense, utilizing the straight-line method, for the cost of stock options, restricted stock units ("RSUs"), performance units ("PUs") and shares of stock issued under our employee stock purchase plan (together, "Employee Stock-Based Awards"). There have been no significant changes to our accounting policies, assumptions and valuation methodologies related to the accounting for our Employee Stock-Based Awards as disclosed in Note 2.n. to Notes to Consolidated Financial Statements included in our Annual Report.

For our Employee Stock-Based Awards made on or after February 20, 2019, we have included the following retirement provision: Upon an employee’s retirement on or after attaining age 58, if the sum of (i) the award recipient’s age at retirement and (ii) the award recipient’s years of service with the company totals at least 70, the award recipient is entitled to continued vesting of any outstanding Employee Stock-Based Awards which include the 2019 Retirement Criteria subsequent to their retirement, provided that, for awards granted in the year of retirement, their retirement occurs on or after July 1st (the “2019 Retirement Criteria”). Accordingly, (i) grants of Employee Stock-Based Awards to an employee who has met the 2019 Retirement Criteria on or before the date of grant, or will meet the Retirement Criteria before July 1^st of the year of the grant, will be expensed between the date of grant and July 1^st of the grant year and (ii) grants of Employee Stock-Based Awards to employees who will meet the 2019 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 2019 Retirement Criteria. Stock options and RSUs granted to recipients who meet the 2019 Retirement Criteria will continue vesting on the original vesting schedule, and the stock options will remain exercisable up to three years after retirement, or the original expiration date of the stock options, if earlier. PUs granted to recipients who meet the 2019 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.

Stock-based compensation expense for Employee Stock-Based Awards for the three months ended March 31, 2019 and 2018 was $8,519 ($7,935 after tax or $0.03 per basic and diluted share) and $7,384 ($6,833 after tax or $0.02 per basic and diluted share), respectively, the substantial majority of which is included in Selling, general and administrative expenses in the accompanying Condensed Consolidated Statements of Operations. As of March 31, 2019, unrecognized compensation cost related to the unvested portion of our Employee Stock-Based Awards was $72,353 and is expected to be recognized over a weighted-average period of 2.2 years.

f. 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 or PUs) that were outstanding during the period, unless the effect is antidilutive.

The calculation of basic and diluted income (loss) per share for the three months ended March 31, 2019 and 2018 is as follows:



	Three Months Ended March 31,
	2019			2018
Income (loss) from continuing operations	$	30,476		$	45,614
Less: Net income (loss) attributable to noncontrolling interests	891			468
Income (loss) from continuing operations (utilized in numerator of Earnings Per Share calculation)	$	29,585		$	45,146
(Loss) income from discontinued operations, net of tax	$	(24	)	$	(462	)
Net income (loss) attributable to Iron Mountain Incorporated	$	29,561		$	44,684

g. Income Taxes

We provide for income taxes during interim periods based on our estimate of the effective tax rate for the year. Our estimate of the effective tax rates for the years ending December 31, 2019 and 2018 reflect the impact of the U.S. tax reform legislation, commonly referred to as the Tax Cuts and Jobs Act (the “Tax Reform Legislation”). See Note 7 to Notes to Consolidated Financial Statements included in our Annual Report for additional information regarding the impact the Tax Reform Legislation had on us. Discrete items and changes in our estimate of the annual effective tax rate are recorded in the period they occur. Our effective tax rate is subject to variability in the future due to, among other items: (1) changes in the mix of income between our qualified REIT subsidiaries ("QRSs") and our domestic taxable REIT subsidiaries ("TRSs"), as well as among the jurisdictions in which we operate; (2) tax law changes; (3) volatility in foreign exchange gains and losses; (4) the timing of the establishment and reversal of tax reserves; and (5) our ability to utilize net operating losses that we generate.

Our effective tax rates for the three months ended March 31, 2019 and 2018 is as follows:



	Three Months Ended March 31,
	2019(1)		2018(2)
Effective Tax Rate	25.7	%	2.5	%

The primary reconciling items between the federal statutory tax rate of 21.0% and our overall effective tax rate for the three months ended March 31, 2019 were the benefit derived from the dividends paid deduction and the impact of differences in the tax rates at which our foreign earnings are subject, including foreign exchange gains and losses in different jurisdictions with different tax rates.

The primary reconciling items between the federal statutory tax rate of 21.0% and our overall effective tax rate for the three months ended March 31, 2018 were the benefit derived from the dividends paid deduction, a discrete tax benefit of approximately $14,000 associated with the resolution of a tax matter and the impact of differences in the tax rates at which our foreign earnings are subject, including foreign exchange gains and losses in different jurisdictions with different tax rates.

h. Fair Value Measurements

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.

(1)	Money market funds and time deposits are measured based on quoted prices for similar assets and/or subsequent transactions.


(2)	Certain trading securities are measured at fair value using quoted market prices.


(3)	Certain trading securities are measured based on inputs other than quoted market prices that are observable.

(4)

Derivative assets and liabilities relate to short-term (six months or less) foreign currency contracts that we have entered into to hedge certain of our foreign exchange intercompany exposures. We calculate the value of such forward contracts by adjusting the spot rate utilized at the balance sheet date for translation purposes by an estimate of the forward points observed in active markets. As of March 31, 2019, we had outstanding forward contracts to (i) purchase 4,000 Euros and sell $4,610 United States dollars and (ii) purchase $4,515 United States dollars and sell 4,000 Euros. As of December 31, 2018, we had outstanding forward contracts to purchase 29,000 Euros and sell $33,374 United States dollars. We have not designated any of the forward contracts we have entered into as hedges.

(5)

We have entered into interest rate swap agreements to limit our exposure to changes in interest rates on a portion of our floating rate indebtedness. As of March 31, 2019 and December 31, 2018, we have $350,000 in notional value of interest rate swap agreements outstanding, which expire in March 2022. Under the interest rate swap agreements, we receive variable rate interest payments associated with the notional amount of each interest rate swap, based upon one-month LIBOR, in exchange for the payment of fixed interest rate payments (at the fixed rate interest specified in the interest rate swap agreements). We have designated these interest rate swaps as cash flow hedges. Unrealized gains are recognized as assets while unrealized losses are recognized as liabilities. The fair value of the interest rate swaps are estimated using industry standard valuation models using market-based observable inputs, including interest rate curves.

j. Other Expense (Income), Net

Other expense (income), net for the three months ended March 31, 2019 and 2018 consists of the following:



	Three Months Ended March 31,
	2019			2018
Foreign currency transaction losses (gains), net	$	17,697		$	21,785
Other, net	(2,487		)	(1,634		)
	$	15,210		$	20,151

The gain or loss on foreign currency transactions, calculated as the difference between the historical exchange rate and the exchange rate at the applicable measurement date, include gains or losses related to (i) borrowings in certain foreign currencies under our Revolving Credit Facility (as defined and discussed more fully in Note 4), (ii) our Euro Notes, (iii) certain foreign currency denominated intercompany obligations of our foreign subsidiaries to us and between our foreign subsidiaries, which are not considered permanently invested, and (iv) amounts that are paid or received on the net settlement amount from forward contracts (as more fully discussed in Note 2.h.).

Other, net for the three months ended March 31, 2019 is primarily comprised of a gain on sale resulting from the Consumer Storage Transaction (as defined and discussed more fully in Note 9) of approximately $4,200. Other, net for the three months ended March 31, 2019 also includes the change in estimated fair value of the noncontrolling interests associated with our business in India, which are accounted for as mandatorily redeemable noncontrolling interests.

k. New Accounting Pronouncements

In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force) ("ASU 2018-15"). ASU 2018-15 aligns the accounting for costs incurred to implement a cloud computing arrangement that is a service arrangement with the guidance on capitalizing costs associated with developing or obtaining internal-use software. We adopted ASU 2018-15 on January 1, 2019. ASU 2018-15 did not have a material impact on our consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02. We adopted ASU 2016-02 on January 1, 2019 on a modified retrospective basis. See Note 2.d. for information regarding the impact of the adoption of ASU 2016-02 on our consolidated financial statements.

l. Change in Presentation

Subsequent to our conversion to a REIT, we have historically classified gains on sale of real estate, net of tax, as a separate line on our consolidated statements of operations and excluded such amounts from our reported operating income. We presented such amounts net of tax as these gains were presented below the provision (benefit) for income taxes on our consolidated statements of operations. Commencing with the first quarter of 2019, we will present gains on sale of real estate as a component of operating income in the line item loss (gain) on disposal/write down of property, plant and equipment, net. Such amounts will be presented gross of tax with any tax impact presented within provision (benefit) for income taxes. All prior periods will be conformed to this presentation going forward. No gains on the sale of real estate were recognized during the three months ended March 31, 2019 or 2018.

(3) Acquisitions (Continued)

See Note 6 to Notes to Consolidated Financial Statements included in our Annual Report for additional information regarding our allocations of the purchase price for acquisitions. The preliminary purchase price allocations that are not finalized as of March 31, 2019 primarily relate to the final assessment of the fair values of intangible assets and liabilities (primarily customer relationship intangible assets and data center lease-based intangible assets), property, plant and equipment (primarily building, building improvements, data center infrastructure and racking structures), right-of-use assets and liabilities associated with acquired operating leases, contingencies and income taxes (primarily deferred income taxes), primarily associated with the EvoSwitch Transaction (as defined in Note 6 to Notes to Consolidated Financial Statements included in our Annual Report), as well as other acquisitions we closed in 2019.

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. 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. Adjustments recorded during the three months ended March 31, 2019 were not material to our results from operations.

Acquisition of IO Data Centers in 2018

On January 10, 2018, we completed the IODC Transaction. At the closing of the IODC Transaction, we paid approximately $1,347,000. In February 2019, we paid approximately $31,000 in additional purchase price associated with the execution of customer contracts from the closing through the one-year anniversary of the IODC Transaction, which was accrued at December 31, 2018. This amount, net of amortization, is reported as a third-party commissions asset as a component of Other within Other assets, net, in our Condensed Consolidated Balance Sheets at March 31, 2019 and December 31, 2018.

The unaudited consolidated pro forma financial information (the "Pro Forma Financial Information") below summarizes the combined results of us and IODC on a pro forma basis as if the IODC Transaction had occurred on January 1, 2017. 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, 2017. The Pro Forma Financial Information, for the period presented, includes purchase accounting adjustments (including amortization expenses from acquired intangible assets and depreciation of acquired property, plant and equipment). We and IODC collectively incurred $28,064 of operating expenditures to complete the IODC 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, 2017.



	Three Months Ended March 31, 2018
Total Revenues	$	1,045,948
Income from Continuing Operations	$	55,566
Per Share Income from Continuing Operations - Basic	$	0.20
Per Share Income from Continuing Operations - Diluted	$	0.19

In addition to our acquisition of IODC, we completed certain other acquisitions during the first three months of 2019 and in fiscal year 2018. The Pro Forma Financial Information does not reflect these acquisitions due to the insignificant impact of these acquisitions on our consolidated results of operations.

See Note 4 to Notes to Consolidated Financial Statements included in our Annual Report for additional information regarding our Credit Agreement and our other long-term debt, including the direct obligors of each of our debt instruments as well as information regarding the fair value of our debt instruments (including the levels of the fair value hierarchy used to determine the fair value of our debt instruments). The levels of the fair value hierarchy used to determine the fair value of our debt as of March 31, 2019 are consistent with the levels of the fair value hierarchy used to determine the fair value of our debt as of December 31, 2018 (which are disclosed in our Annual Report). Additionally, see Note 5 to Notes to Consolidated Financial Statements included in our Annual Report for information regarding which of our consolidated subsidiaries guarantee certain of our debt instruments. There have been no material changes to our long-term debt since December 31, 2018.

Cash Pooling

As described in greater detail in Note 4 to Notes to Consolidated Financial Statements included in our Annual Report, certain of our subsidiaries participate in cash pooling arrangements (the “Cash Pools”) in order to help manage global liquidity requirements. We currently utilize two separate cash pools, one of which we utilize to manage global liquidity requirements for our QRSs (the "QRS Cash Pool") and the other for our TRSs (the "TRS Cash Pool").

The net cash position balances as of March 31, 2019 and December 31, 2018 are reflected as cash and cash equivalents in the Condensed Consolidated Balance Sheets.

Debt Covenants

The Credit Agreement, our 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 certain other 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 indentures or other agreements governing our indebtedness. The Credit Agreement uses EBITDAR-based calculations as the primary measures of financial performance, including leverage and fixed charge coverage ratios.

Our leverage and fixed charge coverage ratios under the Credit Agreement as of March 31, 2019 and December 31, 2018, as well as our leverage ratio under our indentures as of March 31, 2019 and December 31, 2018 are as follows:



	March 31, 2019	December 31, 2018	Maximum/Minimum Allowable
Net total lease adjusted leverage ratio	5.8	5.6	Maximum allowable of 6.5
Net secured debt lease adjusted leverage ratio	2.8	2.6	Maximum allowable of 4.0
Bond leverage ratio (not lease adjusted)	6.1	5.8	Maximum allowable of 6.5-7.0(1)
Fixed charge coverage ratio	2.2	2.2	Minimum allowable of 1.5

______________________________________________________________

(1)

The maximum allowable leverage ratio under our indentures for the 4⁷/₈% Notes, the GBP Notes and the 5¹/₄% Notes is 7.0, while the maximum allowable leverage ratio under the indentures pertaining to our remaining senior and senior subordinated notes is 6.5. In certain instances as provided in our indentures, we have the ability to incur additional indebtedness that would result in our bond leverage ratio exceeding the maximum allowable ratio under our indentures and still remain in compliance with the covenant.

Noncompliance with these leverage and fixed charge coverage ratios would have a material adverse effect on our financial condition and liquidity.

(5) Selected Consolidated Financial Statements of Parent, Guarantors and Non-Guarantors

The following data summarizes the consolidating results of IMI on the equity method of accounting as of March 31, 2019 and December 31, 2018 and for the three months ended March 31, 2019 and 2018 and are prepared on the same basis as the consolidated financial statements.

The Parent Notes, the CAD Notes, the GBP Notes, and the 5³/₈% Notes are guaranteed by the subsidiaries referred to below as the Guarantors. These subsidiaries are 100% owned by IMI. The guarantees are full and unconditional, as well as joint and several.

Additionally, IMI guarantees the CAD Notes, which were issued by Iron Mountain Canada Operations ULC ("Canada Company"), the GBP Notes, which were issued by Iron Mountain (UK) PLC ("IM UK"), and the 5³/₈% Notes, which were issued by Iron Mountain US Holdings, Inc., which is one of the Guarantors. Canada Company and IM UK do not guarantee the Parent Notes. The subsidiaries that do not guarantee the Parent Notes, the CAD Notes, the GBP Notes, and the 5³/₈% Notes are referred to below as the Non-Guarantors.

In the normal course of business, we periodically change the ownership structure of our subsidiaries to meet the requirements of our business. In the event of such changes, we recast the prior period financial information within this footnote to conform to the current period presentation in the period such changes occur. Generally, these changes do not alter the designation of the underlying subsidiaries as Guarantors or Non-Guarantors. However, they may change whether the underlying subsidiary is owned by the Parent, a Guarantor or a Non-Guarantor. If such a change occurs, the amount of investment in subsidiaries in the below Condensed Consolidated Balance Sheets and equity in the earnings (losses) of subsidiaries, net of tax in the below Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) with respect to the relevant Parent, Guarantors, Non-Guarantors and Eliminations columns also would change.

(6) Segment Information (Continued)

The accounting policies of the reportable operating segments are the same as those described in Note 2 and in Note 2 to Notes to Consolidated Financial Statements included in our Annual Report. Adjusted EBITDA for each segment 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, net (including real estate); (ii) intangible impairments; (iii) other expense (income), net (which includes foreign currency transaction (gains) losses, net); and (iv) Significant Acquisition Costs (as defined below). Internally, we use Adjusted EBITDA as the basis for evaluating the performance of, and allocating resources to, our operating segments.

A reconciliation of Adjusted EBITDA to income (loss) from continuing operations on a consolidated basis is as follows:



	Three Months Ended March 31,
	2019		2018
Adjusted EBITDA	$	324,506	$	343,015

(7) Commitments and Contingencies

We are involved in litigation from time to time in the ordinary course of business. 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 able to be estimated. We record legal costs associated with loss contingencies as expenses in the period in which they are incurred. There have been no material updates or changes to the matters disclosed in Note 10 to Notes to Consolidated Financial Statements included in our Annual Report, nor have there been any new material loss contingencies since December 31, 2018. We believe that the resolution of the matters disclosed in Note 10 to Notes to Consolidated Financial Statements included in our Annual Report will not have a material impact on our consolidated financial condition, results of operations or cash flows. We have estimated a reasonably possible range for all loss contingencies, including those disclosed in Note 10 to Notes to Consolidated Financial Statements included in our Annual Report, and believe it is reasonably possible that we could incur aggregate losses in addition to amounts currently accrued for all matters up to an additional $17,500 over the next several years, of which certain amounts would be covered by insurance or indemnity arrangements.

(8) Stockholders' Equity Matters

Our board of directors has adopted a dividend policy under which we have paid, and in the future intend to pay, quarterly cash dividends on our common stock. 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 fiscal year 2018 and the first three months of 2019, our board of directors declared the following dividends:

At The Market (ATM) Equity Program

As described in greater detail in Note 12 to Notes to Consolidated Financial Statements included in our Annual Report, we entered into a distribution agreement with a syndicate of 10 banks (the “Agents”) pursuant to which we may sell, from time to time, up to an aggregate sales price of $500,000 of our common stock through the Agents (the “At The Market (ATM) Equity Program”). There were no shares of common stock sold under the At The Market (ATM) Equity Program during the three months ended March 31, 2019. As of March 31, 2019, the remaining aggregate sale price of shares of our common stock available for distribution under the At The Market (ATM) Equity Program was approximately $431,200.

(9) Divestments

On March 19, 2019, we contributed our customer contracts and certain intellectual property and other assets used by us to operate our consumer storage business in the United States and Canada (the "IM Consumer Storage Assets") and approximately $20,000 in cash (gross of certain transaction expenses) (the "Cash Contribution") to a joint venture entity, Makespace LLC (the "Makespace JV"), established by us and Makespace Labs, Inc. ("Makespace"), a consumer storage services provider (the "Consumer Storage Transaction"). At the closing date of the Consumer Storage Transaction, the Makespace JV owned (i) the IM Consumer Storage Assets, (ii) the Cash Contribution and (iii) the customer contracts, intellectual property and certain other assets used by Makespace to operate its consumer storage business in the United States. As part of the Consumer Storage Transaction, we received an equity interest of approximately 34% in the Makespace JV (the "Makespace Investment"). In connection with the Consumer Storage Transaction and the Makespace Investment, we also entered into a storage and service agreement with the Makespace JV to provide certain storage and related services to the Makespace JV (see Note 11).

We have concluded that the divestment of the IM Consumer Storage Assets in the Consumer Storage Transaction does not meet the criteria to be reported as a discontinued operation in our consolidated financial statements, as our decision to divest this business does not represent a strategic shift that will have a major effect on our operations and financial results. Accordingly, the revenues and expenses associated with this business are presented as a component of income (loss) from continuing operations in our Condensed Consolidated Statements of Operations for the three months ended March 31, 2019 and 2018, respectively, and the cash flows associated with this business are presented as a component of cash flows from continuing operations in our Condensed Consolidated Statements of Cash Flows for the three months ended March 31, 2019 and 2018, respectively, through the closing date of the Consumer Storage Transaction.

As a result of the Consumer Storage Transaction, we recorded a gain on sale of approximately $4,200 to Other expense (income), net, in the first quarter of 2019, representing the excess of the fair value of the consideration received over the sum of (i) the carrying value of our consumer storage operations and (ii) the Cash Contribution. At the closing date of the Consumer Storage Transaction, the fair value of the Makespace Investment was approximately $27,500 and is presented as a component of Other within Other assets, net in our Condensed Consolidated Balance Sheet as of March 31, 2019. We account for the Makespace Investment as an equity method investment.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations for the three months ended March 31, 2019 should be read in conjunction with our Condensed Consolidated Financial Statements and Notes thereto for the three months ended March 31, 2019, included herein, and our Consolidated Financial Statements and Notes thereto for the year ended December 31, 2018, included in our Annual Report on Form 10-K filed with the United States Securities and Exchange Commission ("SEC") on February 14, 2019 (our "Annual Report").

FORWARD-LOOKING STATEMENTS

We have made statements in this Quarterly Report on Form 10-Q ("Quarterly Report") that constitute "forward-looking statements" as that term is defined in the Private Securities Litigation Reform Act of 1995 and other securities laws. These forward-looking statements concern our operations, economic performance, financial condition, goals, beliefs, future growth strategies, investment objectives, plans and current expectations, such as our (1) commitment to future dividend payments, (2) expected growth of records stored with us from existing customers, (3) expected 2019 consolidated organic storage rental revenue growth rate, consolidated organic total revenue growth rate and capital expenditures, (4) expectation that profits will increase in our emerging markets, (5) expectation that our growth portfolio will become a large part of our business over time, (6) statements made in relation (i) to our acquisition of Recall Holdings Limited ("Recall") pursuant to the Scheme Implementation Deed, as amended, with Recall (the "Recall Transaction") and (ii) our acquisition of IO Data Centers, LLC ("IODC"), including the total acquisition expenditures related to Recall and IODC and the cost to integrate Recall into our existing operations, (7) statements regarding our expectation to reduce our leverage ratio and (8) our ability to close pending acquisitions. 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:


•	our ability to remain qualified for taxation as a real estate investment trust for United States federal income tax purposes ("REIT");


•	the adoption of alternative technologies and shifts by our customers to storage of data through non-paper based technologies;


•	changes in customer preferences and demand for our storage and information management services;


•	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;


•	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 information technology ("IT") systems and the impact of such incidents on our reputation and ability to compete;


•	changes in the price for our storage and information management services relative to the cost of providing such storage and information management services;


•	changes in the political and economic environments in the countries in which our international subsidiaries operate and changes in the global political climate;


•	our ability or inability to manage growth, expand internationally, complete acquisitions on satisfactory terms, to close pending acquisitions and to integrate acquired companies efficiently;


•	changes in the amount of our growth and maintenance capital expenditures and our ability to invest according to plan;


•	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;


•	the impact of service interruptions or equipment damage and the cost of power on our data center operations;


•	changes in the cost of our debt;


•	the impact of alternative, more attractive investments on dividends;


•	the cost or potential liabilities associated with real estate necessary for our business;


•	the performance of business partners upon whom we depend for technical assistance or management expertise outside the United States; and


•	other trends in competitive or economic conditions affecting our financial condition or results of operations not presently contemplated.

Table of Contents

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. You should read these cautionary statements as being applicable to all forward-looking statements wherever they appear. 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. Readers are also urged to carefully review and consider the various disclosures we have made in this Quarterly Report, as well as our other periodic reports filed with the SEC including under "Risk Factors" in our Annual Report.

Overview

The following discussions set forth, for the periods indicated, management's discussion and analysis of financial condition and results of operations. Significant trends and changes are discussed for the three month period ended March 31, 2019 within each section.

IODC Acquisition

On January 10, 2018, we completed the acquisition of the United States operations of IODC (the "IODC Transaction"). At the closing of the IODC Transaction, we paid approximately $1,347.0 million. In February 2019, we paid approximately $31.0 million in additional purchase price associated with the execution of customer contracts from the closing through the one-year anniversary of the IODC Transaction. See Note 6 to Notes to Consolidated Financial Statements included in our Annual Report for additional information.

Divestments

a. Consumer Storage Transaction

On March 19, 2019, we contributed our customer contracts and certain intellectual property and other assets used by us to operate our consumer storage business in the United States and Canada (the "IM Consumer Storage Assets") and approximately$20.0 million in cash (gross of certain transaction expenses) (the "Cash Contribution") to a joint venture entity, Makespace LLC (the "Makespace JV"), established by us and Makespace Labs, Inc. ("Makespace"), a consumer storage services provider (the "Consumer Storage Transaction"). At the closing date of the Consumer Storage Transaction, the Makespace JV owned (i) the IM Consumer Storage Assets, (ii) the Cash Contribution and (iii) the customer contracts, intellectual property and certain other assets used by Makespace to operate its consumer storage business in the United States. As part of the Consumer Storage Transaction, we received an equity interest of approximately 34% in the Makespace JV (the "Makespace Investment").

As described in Note 9 to Notes to Condensed Consolidated Financial Statements included in this Quarterly Report, the divestment of the IM Consumer Storage Assets in the Consumer Storage Transaction does not meet the criteria to be reported as a discontinued operations in our consolidated financial statements. In connection with the Consumer Storage Transaction and the Makespace Investment, we also entered into a storage and service agreement with the Makespace JV to provide certain storage and related services to the Makespace JV (the "Makespace Agreement"). Revenues and expenses associated with the Makespace Agreement are presented as a component of our North American Records and Information Management Business segment. For the three months ended March 31, 2019, we recognized an immaterial amount of revenue associated with the Makespace Agreement.

As a result of the Consumer Storage Transaction, we recorded a gain on sale of approximately $4.2 million to Other expense (income), net, in the first quarter of 2019, representing the excess of the fair value of the consideration received over the sum of (i) carrying value of our consumer storage operations and (ii) the Cash Contribution.

b. IMFS Divestment

On September 28, 2018, Iron Mountain Fulfillment Services, Inc., a consolidated subsidiary of Iron Mountain Incorporated ("IMI") that operated our fulfillment services business in the United States, sold substantially all of its assets for total consideration of approximately $3.0 million (the "IMFS Divestment"). As described in Note 13 to Notes to Consolidated Financial Statements in our Annual Report, we have concluded that the IMFS Divestment does not meet the criteria to be reported as discontinued operations in our consolidated financial statements, as our decision to divest this business does not represent a strategic shift that will have a major effect on our operations and financial results. Our fulfillment services business represented approximately $7.4 million and $1.2 million of total revenues and income from continuing operations, respectively, for the three months ended March 31, 2018.

Significant Acquisition Costs

We currently estimate total acquisition and integration expenditures associated with the Recall Transaction and acquisition expenditures associated with the IODC Transaction to be approximately $405.0 million, the substantial majority of which was incurred prior to the end of 2018. From January 1, 2015 through March 31, 2019, we have incurred cumulative operating and capital expenditures associated with the Recall Transaction and the IODC Transaction of $392.0 million, including $317.3 million of Significant Acquisition Costs (as defined in Note 9 to Notes to Consolidated Financial Statements included in our Annual Report) and $74.7 million of capital expenditures. We expect the remaining amount of these operating and capital expenditures will be primarily related to moving costs associated with facility consolidation and system upgrade costs.

General

Our revenues consist of storage rental revenues as well as 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, technology escrow services that protect and manage source code, data backup and storage on our proprietary cloud and 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 and courier operations, consisting primarily of the pickup and delivery of records upon customer request; (2) destruction services, consisting primarily of secure shredding of sensitive documents and the related sale of recycled paper, the price of which can fluctuate from period to period, and customer termination and permanent removal fees; (3) other services, including the scanning, imaging and document conversion services of active and inactive records and project revenues; (4) consulting services; and (5) cloud-related data protection, preservation, restoration and recovery. Our service revenue growth has been negatively impacted by declining activity rates as stored records are becoming less active. While customers continue to store their records and tapes with us, they are less likely than they have been in the past to retrieve records for research and other purposes, thereby reducing service activity levels.

Cost of sales (excluding depreciation and amortization) consists primarily of wages and benefits for field personnel, facility occupancy costs (including rent and utilities), transportation expenses (including vehicle leases and fuel), other product cost of sales and other equipment costs and supplies. Of these, wages and benefits and facility occupancy costs are the most significant. Selling, general and administrative expenses consist primarily of wages and benefits for management, administrative, information technology, sales, account management and marketing personnel, as well as expenses related to communications and data processing, travel, professional fees, bad debts, training, office equipment and supplies.

The expansion of our international businesses has impacted the major cost of sales components and selling, general and administrative expenses. Our international operations are more labor intensive relative to revenue than our operations in North America and, therefore, labor costs are a higher percentage of international segment revenue. In addition, the overhead structure of our expanding international operations has generally not achieved the same level of overhead leverage as our North American segments, which may result in an increase in selling, general and administrative expenses as a percentage of consolidated revenue as our international operations become a larger percentage of our consolidated results.

Our consolidated revenues and expenses are subject to the net effect of foreign currency translation related to our operations outside the United States. It is difficult to predict the future fluctuations of foreign currency exchange rates and how those fluctuations will impact our Consolidated Statements of Operations. As a result of the relative size of our international operations, these fluctuations may be material on individual balances. Our revenues and expenses from our international operations are generally denominated in the local currency of the country in which they are derived or incurred. Therefore, the impact of currency fluctuations on our operating income and operating margin is partially mitigated. In order to provide a framework for assessing how our underlying businesses performed excluding the effect of foreign currency fluctuations, we compare the percentage change in the results from one period to another period in this report using constant currency presentation. The constant currency growth rates are calculated by translating the 2018 results at the 2019 average exchange rates. Constant currency growth rates are a non-GAAP measure.

Non-GAAP Measures

Adjusted EBITDA

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: (1) (gain) loss on disposal/write-down of property, plant and equipment (including real estate), net; (2) intangible impairments; (3) other expense (income), net (which includes foreign currency transaction (gains) losses, net); and (4) 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 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 EPS

Adjusted EPS is defined as reported earnings per share fully diluted from continuing operations excluding: (1) (gain) loss on disposal/write-down of property, plant and equipment (including real estate), net; (2) intangible impairments; (3) other expense (income), net (which includes foreign currency transaction (gains) losses, net); (4) Significant Acquisition Costs; and (5) 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.

The difference between our effective tax rates and our structural tax rate (or adjusted effective tax rates) for the three months ended March 31, 2019 and 2018, respectively, is primarily due to (i) the reconciling items above, which impact our reported income (loss) from continuing operations before provision (benefit) for income taxes but have an insignificant impact on our reported provision (benefit) for income taxes and (ii) other discrete tax items. Our structural tax rate for purposes of the calculation of Adjusted EPS for the three months ended March 31, 2019 and 2018 was 18.9% and 19.5%, respectively.

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: (1) (gain) loss on disposal/write-down of property, plant and equipment (excluding real estate), net; (2) intangible impairments; (3) other expense (income), net (which includes foreign currency transaction (gains) losses, net); (4) real estate financing lease depreciation; (5) Significant Acquisition Costs; (6) the tax impact of reconciling items and discrete tax items; (7) loss (income) from discontinued operations, net of tax; and (8) loss (gain) on sale of discontinued operations, net of tax.

Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations are based upon our Condensed Consolidated Financial Statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the financial statements and for the period then ended. On an ongoing basis, we evaluate the estimates used. We base our estimates on historical experience, actuarial estimates, current conditions and various other assumptions that we believe to be reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of assets and liabilities and are not readily apparent from other sources. Actual results may differ from these estimates. Our critical accounting policies include the following, which are listed in no particular order:


•	Revenue Recognition


•	Accounting for Acquisitions


•	Impairment of Tangible and Intangible Assets


•	Income Taxes

Further detail regarding our critical accounting policies can be found in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report, and the Consolidated Financial Statements and the Notes included therein. We have determined that no material changes concerning our critical accounting policies have occurred since December 31, 2018, other than the adoption of Accounting Standards Update No. 2016-02, Leases (Topic 842), as amended ("ASU 2016-02"), as described in Note 2.d. to Notes to Condensed Consolidated Financial Statements included in this Quarterly Report.

(1)	Constant currency growth rates are calculated by translating the 2018 results at the 2019 average exchange rates.


(2)	Our organic revenue growth rate, which is a non-GAAP measure, represents the year-over-year growth rate of our revenues excluding the impact of business acquisitions, divestitures and foreign currency exchange rate fluctuations. Our organic revenue growth rate includes the impact of acquisitions of customer relationships.

Storage Rental Revenues

In the three months ended March 31, 2019, the increase in reported consolidated storage rental revenues was driven by the favorable impact of acquisitions/divestitures and consolidated organic storage rental revenue growth, partially offset by unfavorable fluctuations in foreign currency exchange rates. The net impact of acquisitions/divestitures contributed 3.1% to the reported storage rental revenue growth rates for the three months ended March 31, 2019 compared to the prior year period, primarily driven by acquisitions in our Global Data Center Business segment. Organic storage rental revenue growth of 2.0% in the three months ended March 31, 2019 compared to the prior year period was driven by organic storage rental revenue growth of 1.4% in our North American Records and Information Management Business segment due to revenue management partially offset by volume decreases, as well as organic storage rental revenue growth of 3.3% and 4.6% in our Western European Business and Other International Business segments, respectively, primarily a result of volume increases and, to a lesser extent, revenue management. Organic storage rental revenue growth in our North American Data Management Business segment was negative 2.9% for the three months ended March 31, 2019 compared to the prior year period primarily due to lower storage volume, partially offset by the impact of revenue management. Excluding the impact of acquisitions/divestitures, global records management net volumes as of March 31, 2019 increased by 0.3% over the ending volume as of March 31, 2018. Including the impact of acquisitions/divestitures, global records management net volumes as of March 31, 2019 increased by 1.5% over the ending volume at March 31, 2018, supported by net volume increases of 2.2% and 7.3% in our Western European Business and Other International Business segments, respectively, partially offset by a net volume decrease of 1.2% in our North American Records and Information Management Business segment. Foreign currency exchange rate fluctuations decreased our reported storage rental revenue growth rate for the three months ended March 31, 2019 by 3.3%, compared to the prior year period.

Service Revenues

In the three months ended March 31, 2019, the decrease in reported consolidated service revenues was driven by unfavorable fluctuations in foreign currency exchange rates, offset by organic service revenue growth and the favorable impact of acquisitions/divestitures. Foreign currency exchange rate fluctuations decreased our reported service revenue growth rate for the three months ended March 31, 2019 by 3.6%, compared to the prior year period. Organic service revenue growth of 1.8% for the three months ended March 31, 2019, compared to the prior year period was driven by organic service revenue growth of 2.3% in our North American Records and Information Management Business segment reflecting increased secured shredding revenues, primarily due to higher recycled paper prices, and project activity, partially offset by lower destructions, as well as organic service revenue growth of 3.0% in our Western European Business segment, primarily due to higher destruction activity, partially offset by continued declines in organic service revenue activity levels in our North American Data Management Business segment of negative 3.2%, as the storage business in this segment becomes more archival in nature and tape volumes decline. The net impact of acquisitions/divestitures contributed 1.7% to the reported service revenue growth rates for the three months ended March 31, 2019, compared to the prior year period.

Total Revenues

For the reasons stated above, our reported consolidated revenues increased $11.4 million, or 1.1%, to $1,053.9 million for the three months ended March 31, 2019 from $1,042.5 million for the three months ended March 31, 2018. The net impact of acquisitions/divestitures contributed 2.6% to the reported consolidated revenue growth rate for the three months ended March 31, 2019 compared to the prior year period. Consolidated organic revenue growth was 1.9% in the three months ended March 31, 2019 compared to the prior year period. Foreign currency exchange rate fluctuations decreased our reported consolidated revenue growth rate for the three months ended March 31, 2019 by 3.4%, compared to the prior year period.

Organic Growth—Eight-Quarter Trend



	2017						2018								2019
	Second Quarter		Third Quarter		Fourth Quarter		First Quarter		Second Quarter		Third Quarter		Fourth Quarter		First Quarter
Storage Rental Revenue	4.8	%	3.5	%	4.2	%	3.7	%	1.9	%	2.3	%	1.9	%	2.0	%
Service Revenue	(1.1	)%	(0.2	)%	(0.1	)%	1.4	%	7.6	%	7.1	%	6.1	%	1.8	%
Total Revenues	2.5	%	2.0	%	2.5	%	2.8	%	4.1	%	4.1	%	3.5	%	1.9	%

We expect our consolidated organic storage rental revenue growth rate for 2019 to be approximately 1.75% to 2.5% and our consolidated organic total revenue growth rate to be approximately 2.0% to 2.5%. During the past eight quarters, our organic storage rental revenue growth rate has ranged between 1.9% and 4.8%. Consolidated organic storage rental revenue growth and consolidated total organic revenue growth benefited by approximately 0.8% and 0.5%, respectively, in the second quarter of 2017, from a $4.2 million customer termination fee in our Global Data Center Business segment. Conversely, consolidated organic storage rental revenue growth and consolidated total organic revenue growth for the second quarter of 2018 were negatively impacted by the 0.8% and 0.5%, respectively, related to this termination fee. Our organic storage rental revenue growth rates have declined over the past two fiscal years, as organic storage rental revenue growth for full year 2017 and 2018 was 3.9% and 2.4%, respectively. At various points in the economic cycle, organic storage rental revenue growth may be influenced by changes in pricing and volume. In 2018 and in the three months ended March 31, 2019, we experienced modest volume declines in our North American Records and Information Management Business and North American Data Management Business segments, with organic storage rental revenue growth coming primarily from revenue management in these segments and volume growth in our Western European Business and Other International Business segments. Within these business segments, we expect these trends to continue into the next few years.

The organic growth rate for service revenue is inherently more volatile than the organic growth rate for storage rental revenues due to the more discretionary nature of certain services we offer, such as large special projects, and, as a commodity, the volatility of pricing for recycled paper. These revenues, which are often event-driven and impacted to a greater extent by economic downturns as customers defer or cancel the purchase of certain services as a way to reduce their short-term costs, may be difficult to replicate in future periods. The organic growth rate for total service revenues over the past eight quarters reflects reduced retrieval/re-file activity and a related decrease in transportation revenues within our North American Records and Information Management Business and Western European Business segments, as well as continued declines in service revenue activity levels in our North American Data Management Business segment, as the storage business becomes more archival in nature and tape volumes decline. The recent increases in organic service revenue growth rates of 7.6%, 7.1% and 6.1% in the second, third and fourth quarters of 2018 reflect a strong contribution from our secure shredding business, which benefited from higher recycled paper prices, higher destruction activity and acquisitions of customer relationships. Organic service revenue growth declined to 1.8% for the first quarter of 2019 reflecting declining recycled paper prices and moderation of destruction activity compared to previous quarters. We expect these trends to continue throughout 2019.

Labor

Labor expenses decreased to 19.5% of consolidated revenues in the three months ended March 31, 2019 compared to 20.0% in the three months ended March 31, 2018. The decrease in labor expenses as a percentage of consolidated revenues was primarily driven by basis point improvements across our North American Records and Information Management Business, Western European Business and Other International Business segments, partially attributable to ongoing cost management initiatives. On a constant dollar basis, labor expenses for the three months ended March 31, 2019 increased by $5.0 million, or 2.5%, compared to the prior year period, primarily driven by acquisitions in our Global Data Center Business segment and our Adjacent Businesses operating segment within our Corporate and Other Business segment, as well as increased labor costs related to shredding operations within our North American Records and Information Management Business segment.

Facilities

Facilities expenses increased to 16.6% of consolidated revenues in the three months ended March 31, 2019 compared to 15.6% in the three months ended March 31, 2018. The 100 basis point increase in facilities expenses as a percentage of consolidated revenues was driven primarily by acquisitions in our Global Data Center Business segment and our Adjacent Businesses operating segment within our Corporate and Other Business segment, as well as higher facilities costs in our Western European Business segment. On a constant dollar basis, facilities expenses for the three months ended March 31, 2019 increased by $18.5 million, or 11.6%, compared to the prior year period, primarily driven by acquisitions mentioned above and higher facilities costs in our Western European Business segment.

Transportation

Transportation expenses increased to 3.9% of consolidated revenues in the three months ended March 31, 2019 compared to 3.7% in the three months ended March 31, 2018. The increase in transportation expenses as a percentage of consolidated revenues was primarily driven by increases in third party carrier expenses, in part due to recent acquisitions in our Adjacent Businesses operating segment within our Corporate and Other Business segment. On a constant dollar basis, transportation expenses for the three months ended March 31, 2019 increased by $4.2 million, or 11.3%, compared to the prior year period, primarily driven by increases in third party carrier expenses, in part due to recent acquisitions in our Adjacent Businesses operating segment within our Corporate and Other Business segment, as well as higher transportation cost for shredding operations within our North American Records and Information Management Business segment.

Product Cost of Sales and Other

Product cost of sales and other, which includes cartons, media and other service, storage and supply costs and is highly correlated to service revenue streams, particularly project revenues, were 3.8% of consolidated revenues for the three months ended March 31, 2019 compared to 3.8% in the three months ended March 31, 2018. On a constant dollar basis, product cost of sales and other increased by $2.2 million, or 5.9%, compared to the prior year period, primarily driven by special project costs in our North American Records and Information Management Business segment.

The increase in general and administrative expenses as a percentage of consolidated revenues was driven mainly by higher compensation and professional fees within the Corporate and Other Business segment, primarily associated with our new global operations support team that is tasked with driving operational improvements, and acquisitions in the Global Data Center Business segment. On a constant dollar basis, general and administrative expenses for the three months ended March 31, 2019 increased by $19.2 million, or 14.6%, compared to the prior year period, primarily driven by increases in compensation and professional fees related to our global operations support team.

Bad Debt Expense

We maintain an allowance for doubtful accounts that is calculated based on our past loss experience, current and prior trends in our aged receivables, current economic conditions, and specific circumstances of individual receivable balances. We continue to monitor our customers' payment activity and make adjustments based on their financial condition and in light of historical and expected trends. Bad debt expense for the three months ended March 31, 2019 decreased by $1.2 million on a constant dollar basis compared to the prior year period, primarily driven by lower bad debt expense associated with our Western European and Other International Business segments.

Significant Acquisition Costs

Significant Acquisition Costs included in selling, general and administrative expenses were $1.8 million and $18.7 million in the three months ended March 31, 2019 and 2018, respectively, and primarily consisted of advisory and professional fees, as well as severance costs.

Depreciation and Amortization

Our depreciation and amortization charges result primarily from depreciation related to storage systems, which include racking structures, buildings, building and leasehold improvements and computer systems hardware and software. Amortization relates primarily to customer relationship intangible assets, contract fulfillment costs and data center lease-based intangible assets. Both depreciation and amortization are impacted by the timing of acquisitions.

Depreciation expense increased $1.2 million, or 1.0%, on a reported dollar basis for the three months ended March 31, 2019 compared to the three months ended March 31, 2018. See Note 2.f. to Notes to Consolidated Financial Statements included in our Annual Report for additional information regarding the useful lives over which our property, plant and equipment is depreciated.

Interest Expense, Net

Consolidated interest expense, net increased $4.8 million, or 4.9%, to $102.4 million in the three months ended March 31, 2019 from $97.6 million in the three months ended March 31, 2018. This increase was a result of higher average debt outstanding and higher weighted average interest rate during the three months ended March 31, 2019. Our weighted average interest rate was 4.9% and 4.8% at March 31, 2019 and 2018, respectively. See Note 4 to Notes to Condensed Consolidated Financial Statements included in this Quarterly Report for additional information regarding our indebtedness.

	$	15,210		$	20,151		$	(4,941	)

Foreign Currency Transaction Losses (Gains)

We recorded net foreign currency transaction losses of $17.7 million in the three months ended March 31, 2019, based on period-end exchange rates. These losses resulted primarily from the impact of changes in the exchange rate of each of the British pound sterling and Euro against the United States dollar compared to December 31, 2018 on our intercompany balances with and between certain of our subsidiaries.

We recorded net foreign currency transaction losses of $21.8 million in the three months ended March 31, 2018, based on period-end exchange rates. These losses resulted primarily from the impact of changes in the exchange rate of each of the British pound sterling and Euro against the United States dollar compared to December 31, 2017 on our intercompany balances with and between certain of our subsidiaries and the Euro Notes (as defined below). These losses were partially offset by gains resulting primarily from the impact of changes in the exchange rate of the Canadian dollar against the United States dollar compared to December 31, 2017 on our intercompany balances with and between certain of our subsidiaries.

Other, net

Other, net for the three months ended March 31, 2019 is primarily associated with the gain on sale resulting from the Consumer Storage Transaction (as defined and discussed more fully in Note 9 to Notes to Condensed Consolidated Financial Statements included in this Quarterly Report) of approximately $4.2 million. Other, net for the three months ended March 31, 2019 also includes the change in estimated fair value of the noncontrolling interests associated with our business in India, which are accounted for as mandatorily redeemable noncontrolling interests.

Provision for Income Taxes

We provide for income taxes during interim periods based on our estimate of the effective tax rate for the year. Our estimate of the effective tax rate for the years ending December 31, 2019 and 2018 reflect the impact of the U.S. tax reform legislation, commonly referred to as the Tax Cuts and Jobs Act (the “Tax Reform Legislation”). See Note 7 to Notes to Consolidated Financial Statements included in our Annual Report for additional information regarding the impact the Tax Reform Legislation had on us. Discrete items and changes in our estimate of the annual effective tax rate are recorded in the period they occur. Our effective tax rate is subject to variability in the future due to, among other items: (1) changes in the mix of income between our qualified REIT subsidiaries and our domestic taxable REIT subsidiaries, as well as among the jurisdictions in which we operate; (2) tax law changes; (3) volatility in foreign exchange gains and losses; (4) the timing of the establishment and reversal of tax reserves; and (5) our ability to utilize net operating losses that we generate.

Table of Contents

Our effective tax rates for the three months ended March 31, 2019 and 2018 are as follows:

The primary reconciling items between the federal statutory tax rate of 21.0% and our overall effective tax rate for the three months ended March 31, 2018 were the benefit derived from the dividends paid deduction, a discrete tax benefit of approximately $14.0 million associated with the resolution of a tax matter and the impact of differences in the tax rates at which our foreign earnings are subject, including foreign exchange gains and losses in different jurisdictions with different tax rates.

INCOME (LOSS) FROM CONTINUING OPERATIONS AND ADJUSTED EBITDA (in thousands)

The following table reflects the effect of the foregoing factors on our consolidated income (loss) from continuing operations and Adjusted EBITDA:



	Three Months Ended March 31,						Dollar Change			Percentage Change
	2019			2018			Dollar Change			Percentage Change
Income from Continuing Operations	$	30,476		$	45,614		$	(15,138	)	(33.2	)%

Adjusted EBITDA	$	324,506		$	343,015		$	(18,509	)	(5.4	)%
Adjusted EBITDA Margin	30.8		%	32.9		%

Consolidated Adjusted EBITDA for the three months ended March 31, 2019 decreased by $18.5 million, or approximately 5.4%, and consolidated Adjusted EBITDA Margin decreased by 210 basis points compared to the same prior year period, primarily as a result of increased labor costs in our secure shredding business, higher technology costs associated with information security investments and higher overhead expenses associated with the growth of our data center business.

(LOSS) INCOME FROM DISCONTINUED OPERATIONS, NET OF TAX

Loss from discontinued operations, net of tax was $0.5 million for the three months ended March 31, 2018, primarily related to the costs associated with the Recall Divestments (as discussed in Note 13 to Notes to Consolidated Financial Statements in our Annual Report).

NONCONTROLLING INTERESTS

For the three months ended March 31, 2019 and 2018, net income attributable to noncontrolling interests resulted in a decrease in net income attributable to IMI of $0.9 million and $0.5 million, respectively. These amounts represent our noncontrolling partners' share of earnings/losses in our majority-owned international subsidiaries that are consolidated in our operating results.

For the three months ended March 31, 2019, reported revenue in our North American Records and Information Management Business segment increased 0.1%, compared to the three months ended March 31, 2018, due to organic revenue growth, offset by the unfavorable net impact of acquisitions/dispositions (due to the IMFS Divestment) and foreign currency exchange rates. Organic revenue growth of 1.8% was primarily the result of organic storage rental revenue growth of 1.4% driven by revenue management, partially offset by volume decreases. In addition, organic service revenue growth of 2.3% was driven by growth in secure shredding revenue, in part due to higher recycled paper prices, and increased project activity, partially offset by lower destruction activity compared to the first quarter of 2018. Adjusted EBITDA margin decreased 40 basis points during the three months ended March 31, 2019 compared to the three months ended March 31, 2018, primarily driven by higher labor and transportation costs in our secure shredding business.

For the three months ended March 31, 2019, reported revenue in our North American Data Management Business segment decreased 3.2%, compared to the three months ended March 31, 2018, primarily due to negative organic revenue growth. The negative organic revenue growth of 3.0% was primarily attributable to a decline in organic service revenue growth of 3.2% due to continued declines in service revenue activity levels as the business becomes more archival in nature and tape volumes decline, as well as a decline in organic storage rental revenue of 2.9%, primarily attributable to volume decreases, partially offset by the impact of revenue management. Adjusted EBITDA margin decreased 160 basis points during the three months ended March 31, 2019 compared to the three months ended March 31, 2018, primarily associated with investments in new products and services, as well as lower revenue not being offset by lower fixed costs.

For the three months ended March 31, 2019, reported revenue in our Western European Business segment decreased 4.0%, compared to the three months ended March 31, 2018, due to unfavorable fluctuations in foreign currency exchange rates, partially offset by organic revenue growth. Organic revenue growth was 3.2%, primarily attributable to organic storage rental revenue growth of 3.3%, primarily associated with volume increases and, to a lesser extent, revenue management, as well as organic service revenue growth of 3.0%, reflecting higher destruction activity. For the three months ended March 31, 2019, foreign currency exchange rate fluctuations decreased our reported revenues for the Western European Business segment by 7.2% compared to the prior year period due to the weakening of the British pound sterling and Euro against the United States dollar. Adjusted EBITDA margin decreased 230 basis points during the three months ended March 31, 2019 compared to the three months ended March 31, 2018, primarily driven by higher facilities costs and professional fees, partially offset by lower bad debt expense and labor costs growing at a lower rate than revenue.

In the three months ended March 31, 2019, reported revenue in our Other International Business segment decreased 4.7%, compared to the three months ended March 31, 2018, due to unfavorable fluctuations in foreign currency exchange rates, partially offset by organic revenue growth and the favorable impact of acquisitions/divestitures. Organic revenue growth was 2.7%, supported by 4.6% organic storage rental revenue growth, primarily due to volume increases and, to a lesser extent, revenue management, and negative 0.6% organic service revenue growth, primarily due to a decrease in project activity. The net impact of acquisitions/divestitures contributed 3.2% to reported revenue growth for the three months ended March 31, 2019, compared to the prior year period. For the three months ended March 31, 2019, foreign currency exchange rate fluctuations decreased our reported revenues for the Other International Business segment by 10.6% compared to the prior year period primarily due to the weakening of the Australian dollar and Brazilian real against the United States dollar. Adjusted EBITDA margin increased 10 basis points for the three months ended March 31, 2019 compared to the three months ended March 31, 2018, primarily due to compensation growing at a lower rate than revenue and a decrease in transportation costs.

Financial Instruments and Debt

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. The only significant concentration of liquid investment as of March 31, 2019 is related to cash and cash equivalents. See Note 2.h. to Notes to the Condensed Consolidated Financial Statements included in this Quarterly Report for information on our time deposits.

Long-term debt as of March 31, 2019 is as follows (in thousands):

Debt Covenants

Table of Contents



	March 31, 2019	December 31, 2018	Maximum/Minimum Allowable
Net total lease adjusted leverage ratio	5.8	5.6	Maximum allowable of 6.5
Net secured debt lease adjusted leverage ratio	2.8	2.6	Maximum allowable of 4.0
Bond leverage ratio (not lease adjusted)	6.1	5.8	Maximum allowable of 6.5-7.0(1)
Fixed charge coverage ratio	2.2	2.2	Minimum allowable of 1.5

______________________________________________________________

(1)

Noncompliance with these leverage and fixed charge coverage ratios would have a material adverse effect on our financial condition and liquidity.

_______________________________________________________________________________

Our ability to pay interest on or to refinance our indebtedness depends on our future performance, working capital levels and capital structure, which are subject to general economic, financial, competitive, legislative, regulatory and other factors which may be beyond our control. There can be no assurance that we will generate sufficient cash flow from our operations or that future financings will be available on acceptable terms or in amounts sufficient to enable us to service or refinance our indebtedness or to make necessary capital expenditures.

At The Market (ATM) Equity Program

As described in greater detail in Note 12 to Notes to Consolidated Financial Statements included in our Annual Report, we entered into a distribution agreement with a syndicate of 10 banks (the “Agents”) pursuant to which we may sell, from time to time, up to an aggregate sales price of $500.0 million of our common stock through the Agents (the “At The Market (ATM) Equity Program”). There were no shares of common stock sold under the At the Market (ATM) Equity Program during the three months ended March 31, 2019. During the three months ended March 31, 2018 under the At The Market (ATM) Equity Program, we sold an aggregate of 273,486 shares of common stock for gross proceeds of approximately $8.8 million, generating net proceeds of $8.7 million, after deducting commissions of $0.1 million. As of March 31, 2019, the remaining aggregate sale price of shares of our common stock available for distribution under the At The Market (ATM) Equity Program was approximately $431.2 million.

Acquisitions

See Note 3 to Notes to Condensed Consolidated Financial Statements included in this Quarterly Report for information regarding our 2019 acquisitions.

Included in Significant Acquisition Costs are certain costs associated with the Recall Transaction and the IODC Transaction. This amount consists of (i) Significant Acquisition Costs and (ii) capital expenditures to integrate Recall with our existing operations. We currently estimate total acquisition and integration expenditures associated with the Recall Transaction and acquisition expenditures associated with the IODC Transaction to be approximately $405.0 million, the substantial majority of which was incurred prior to the end of 2018.

The following table presents the cumulative amount of operating and capital expenditures incurred during the three months ended March 31, 2019 and 2018, as well as the cumulative amount incurred through March 31, 2019, associated with the Recall Transaction and the IODC Transaction (in thousands):



	Cumulative Total Through March 31, 2019		Three Months Ended March 31, 2019		Three Months Ended March 31, 2018
Significant Acquisition Costs	$	317,270	$	2,746	$	19,008
Recall Capital Expenditures	74,730		1,193		1,884
Total	$	392,000	$	3,939	$	20,892

Contractual Obligations

We expect to meet our cash flow requirements for the next twelve months by utilizing cash on hand, cash generated from operations, borrowings under the Credit Agreement and other financings (including the issuance of equity under the At The Market (ATM) Equity Program). We expect to meet our long-term cash flow requirements using the same resources described above. We are currently operating above our long-term targeted leverage ratio and expect to reduce our leverage ratio over time through business growth and effective capital allocation strategies.

Inflation

Certain of our expenses, such as wages and benefits, insurance, occupancy costs and equipment repair and replacement, are subject to normal inflationary pressures. Although to date we have been able to offset inflationary cost increases with increased operating efficiencies, the negotiation of favorable long-term real estate leases and an ability to increase prices in our customer contracts (many of which contain provisions for inflationary price escalators), we can give no assurance that we will be able to offset any future inflationary cost increases through similar efficiencies, leases or increased storage rental or service charges.

Sale of Facilities

In April 2019, we completed the sale of two owned facilities in the United Kingdom for total proceeds of approximately $43.0 million.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

The term "disclosure controls and procedures" is defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). These rules refer to the controls and other procedures of a company that are designed to ensure that information is recorded, processed, accumulated, summarized, communicated and reported to management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding what is required to be disclosed by a company in the reports that it files under the Exchange Act. As of March 31, 2019 (the "Evaluation Date"), we carried out an evaluation, under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of our disclosure controls and procedures. Based upon that evaluation, our chief executive officer and chief financial officer concluded that, as of the Evaluation Date, our disclosure controls and procedures are effective.

Changes in Internal Control over Financial Reporting

Our management, with the participation of our principal executive officer and principal financial officer, is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Our internal control system is designed to provide reasonable assurance to our management and board of directors regarding the preparation and fair presentation of published financial statements.

During the quarter ended March 31, 2019, we adopted ASU 2016-02 effective January 1, 2019. In connection with the adoption of ASU 2016-02, we implemented a new lease accounting system and also redesigned certain processes and controls pertaining to our lease portfolio. There were no other changes in our internal control over financial reporting during the quarter ended March 31, 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
