Excluding the impact of foreign currency exchange ("Fx"), total reported revenues increased 9.4% compared to the prior year, driven by an 8.8% increase in storage rental revenue and a 10.2% increase in service revenue.

Net Income for the first quarter was $16.2 million, compared with $77.0 million in the first quarter of 2024, primarily driven by the impact of changes in the exchange rates on our intercompany balances.

Adjusted EBITDA for the first quarter was $579.9 million, compared with $518.9 million in the first quarter of 2024, an increase of 11.8%. On a constant currency basis, Adjusted EBITDA increased by 13.5% in the first quarter, compared to the first quarter of 2024, driven by increased revenue in our Global RIM, ALM, and Data Center businesses and improved operating leverage coming from our continued improvement activities.

FFO (Normalized) per share was $0.77 for the first quarter, compared with $0.74 in the first quarter of 2024.

AFFO was $348.4 million for the first quarter, compared with $323.7 million in the first quarter of 2024, an increase of 7.6% driven by improved Adjusted EBITDA.

AFFO per share was $1.17 for the first quarter, compared with $1.10 in the first quarter of 2024.

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

Reconciliation of Non-GAAP Measures

Throughout this press release, Iron Mountain discusses (1) Adjusted EBITDA, (2) Adjusted EPS, (3) FFO (Nareit), (4) FFO (Normalized), (5) AFFO and (6) AFFO per share. These measures do not conform to accounting principles generally accepted in the United States ("GAAP"). These non-GAAP measures are supplemental metrics designed to enhance our disclosure and to provide additional information that we believe to be important for investors to consider in addition to, but not as a substitute for, other measures of financial performance reported in accordance with GAAP, such as operating income, net income (loss) attributable to Iron Mountain Incorporated or cash flows from operating activities (as determined in accordance with GAAP). The reconciliation of these measures to the appropriate GAAP measure, as required by Regulation G under the Securities Exchange Act of 1934, as amended, and their definitions are included later in this release.

Adjusted EBITDA

We define Adjusted EBITDA as net income (loss) before interest expense, net, provision (benefit) for income taxes, depreciation and amortization (inclusive of our share of Adjusted EBITDA from our unconsolidated joint ventures), and excluding certain items we do not believe to be indicative of our core operating results, specifically: (i) Acquisition and Integration Costs; (ii) Restructuring and other transformation; (iii) Loss (gain) on disposal/write-down of property, plant and equipment, net (including real estate); (iv) Other expense (income), net; (v) Stock-based compensation expense; and (vi) Intangible impairments. Adjusted EBITDA Margin is calculated by dividing Adjusted EBITDA by total revenues. We use multiples of current or projected Adjusted EBITDA in conjunction with our discounted cash flow models to determine our estimated overall enterprise valuation and to evaluate acquisition targets. We believe Adjusted EBITDA and Adjusted EBITDA Margin provide our current and potential investors with relevant and useful information regarding our ability to generate cash flows to support business investment. These measures are an integral part of the internal reporting system we use to assess and evaluate the operating performance of our business.

(1) The difference between our effective tax rates and our structural tax rate (or adjusted effective tax rates) for the three months ended March 31, 2025, March 31, 2024 and December 31, 2024 is primarily due to (i) the reconciling items above, which impact our reported net income (loss) before provision (benefit) for income taxes but have an insignificant impact on our reported provision (benefit) for income taxes and (ii) other discrete tax items. Our structural tax rate for purposes of the calculation of Adjusted EPS for the quarters ended March 31, 2025 and 2024 was 17.0% and 13.9% respectively, and quarter ended December 31, 2024 was 15.6%.

Adjusted Earnings Per Share, or Adjusted EPS

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

(1) Includes depreciation expense related to owned real estate assets (land improvements, buildings, building and leasehold improvements, data center infrastructure and racking structures), excluding depreciation related to real estate financing leases.

(2) Includes amortization expense for Data Center In-Place Lease Intangible Assets and Data Center Tenant Relationship Intangible Assets.

(3) Represents the tax impact of (i) the reconciling items above, which impact our reported net income (loss) before provision (benefit) for income taxes but have an insignificant impact on our reported provision (benefit) from income taxes and (ii) other discrete tax items.

Funds From Operations, or FFO (Nareit), and FFO (Normalized)

Funds from operations ("FFO") is defined by the National Association of Real Estate Investment Trusts as net income (loss) excluding depreciation on real estate assets, losses and gains on sale of real estate, net of tax, and amortization of data center leased-based intangibles ("FFO (Nareit)"). We calculate our FFO measure, including FFO (Nareit), adjusting for our share of reconciling items from our unconsolidated joint ventures. FFO (Nareit) does not give effect to real estate depreciation because these amounts are computed, under GAAP, to allocate the cost of a property over its useful life. Because values for well-maintained real estate assets have historically increased or decreased based upon prevailing market conditions, we believe that FFO (Nareit) provides investors with a clearer view of our operating performance. Our most directly comparable GAAP measure to FFO (Nareit) is net income (loss).

We modify FFO (Nareit), as is common among REITs seeking to provide financial measures that most meaningfully reflect their particular business ("FFO (Normalized)"). Our definition of FFO (Normalized) excludes certain items included in FFO (Nareit) that we believe are not indicative of our core operating results, specifically: (i) Acquisition and Integration Costs; (ii) Restructuring and other transformation; (iii) Loss (gain) on disposal/write-down of property, plant and equipment, net (excluding real estate); (iv) Other expense (income) net; (v) Stock-based compensation expense; (vi) Non-cash amortization related to derivative instruments; (vii) Real estate financing lease depreciation; (viii) Tax impact of reconciling items and discrete tax items; (ix) Intangible impairments; and (x) (Income) loss from discontinued operations, net of tax.


FFO (Normalized) per share FFO (Normalized) divided by weighted average fully-diluted shares outstanding.

Adjusted Funds From Operations, or AFFO

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

AFFO per share

AFFO divided by weighted average fully-diluted shares outstanding.
