The Company does not provide a reconciliation for non-GAAP estimates on a forward-looking basis, as it is unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the timing and/or amount of various items that would impact net income attributable to common stockholders per diluted share, which is the most directly comparable forward-looking GAAP financial measure. This includes, for example, external growth factors, such as dispositions, and balance sheet items, such as debt issuances, that have not yet occurred, are out of the Company's control and/or cannot be reasonably predicted. For the same reasons, the Company is unable to address the probable significance of the unavailable information. Forward-looking non-GAAP financial measures provided without the most directly comparable GAAP financial measures may vary materially from the corresponding GAAP financial measures. 1) Adjusted EBITDA, Same-Capital Cash NOI Growth, Core FFO per Share (excluding net promote), and Constant-Currency Core FFO (excluding net promote) per Share are non-GAAP financial measures.

Appendix 3Q26 Financial Results 17

Appendix Management Statements on Non-GAAP Measures 3Q26 Financial Results 18 The information included in this presentation contains certain non-GAAP financial measures that management believes are helpful in understanding our business, as further described below. Our definition and calculation of non-GAAP financial measures may differ from those of other REITs, and, therefore, may not be comparable. The non-GAAP financial measures should not be considered alternatives to net income or any other GAAP measurement of performance and should not be considered an alternative to cash flows from operating, investing or financing activities as a measure of liquidity. Funds From Operations (FFO): We calculate funds from operations, or FFO, in accordance with the standards established by the National Association of Real Estate Investment Trusts (Nareit) in the Nareit Funds From Operations White Paper - 2018 Restatement. FFO is a non-GAAP financial measure and represents net income (loss) available to common stockholders (computed in accordance with GAAP), excluding gain (loss) from the disposition of real estate assets, provision for impairment, real estate related depreciation and amortization (excluding amortization of deferred financing costs), our share of unconsolidated JV real estate related depreciation & amortization, net income attributable to noncontrolling interests in operating partnership and reconciling items related to noncontrolling interests. Management uses FFO as a supplemental performance measure because, in excluding real estate related depreciation and amortization and gains and losses from property dispositions and after adjustments for unconsolidated partnerships and joint ventures, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. We also believe that, as a widely recognized measure of the performance of REITs, FFO will be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our data centers that result from use or market conditions, nor the level of capital expenditures and capitalized leasing commissions necessary to maintain the operating performance of our data centers, all of which have real economic effect and could materially impact our financial condition and results from operations, the utility of FFO as a measure of our performance is limited. Other REITs may not calculate FFO in accordance with the Nareit definition and, accordingly, our FFO may not be comparable to other REITs’ FFO. FFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance. Core Funds from Operations (Core FFO) and Core FFO (excluding net promote): We present core funds from operations, or Core FFO, and Core FFO (excluding net promote) as supplemental operating measures because, in excluding certain items that do not reflect core revenue or expense streams, they provide a performance measure that, when compared year over year, capture trends in our core business operating performance. We calculate Core FFO by adding to or subtracting from FFO (i) other non-core revenue adjustments, (ii) transaction and integration expenses, (iii) gain (loss) on debt extinguishment and modifications, (iv) gain on / issuance costs associated with redeemed preferred stock, (v) severance, equity acceleration and legal expenses, (vi) gain/loss on FX and derivatives revaluation, and (vii) other non-core expense adjustments. We calculate Core FFO (excluding net promote) by adding to Core FFO the net impact of (i) promote income and (ii) promote expense (collectively “net promote”). Because certain of these adjustments have a real economic impact on our financial condition and results from operations, the utility of Core FFO and Core FFO (excluding net promote) as a measure of our performance is limited. Other REITs may calculate Core FFO and Core FFO (excluding net promote) differently than we do and accordingly, our Core FFO and Core FFO (excluding net promote) may not be comparable to other REITs’ Core FFO and Core FFO (excluding net promote). Core FFO and Core FFO (excluding net promote) should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance. Adjusted Funds from Operations (AFFO): We present adjusted funds from operations, or AFFO, as a supplemental operating measure because, when compared year over year, it assesses our ability to fund dividend and distribution requirements from our operating activities. We also believe that, as a widely recognized measure of the operations of REITs, AFFO will be used by investors as a basis to assess our ability to fund dividend payments in comparison to other REITs, including on a per share and unit basis. We calculate AFFO by adding to or subtracting from Core FFO (i) non-real estate depreciation, (ii) amortization of deferred financing costs, (iii) amortization of debt discount/premium, (iv) non-cash stock-based compensation expense, (v) straight-line rental revenue, (vi) straight-line rental expense, (vii) above- and below-market rent amortization, (viii) deferred tax expense / (benefit), (ix) leasing compensation and internal lease commissions, and (x) recurring capital expenditures. Other REITs may calculate AFFO differently than we do and, accordingly, our AFFO may not be comparable to other REITs’ AFFO. AFFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance. EBITDA and Adjusted EBITDA: We believe that earnings before interest expense, gain (loss) on debt extinguishment and modifications, income tax expense (benefit), and depreciation and amortization, or EBITDA, and Adjusted EBITDA (as defined below), are useful supplemental performance measures because they allow investors to view our performance without the impact of non-cash depreciation and amortization or the cost of debt and, with respect to Adjusted EBITDA, (i) unconsolidated entities real estate related depreciation & amortization, (ii) unconsolidated entities interest expense and tax expense, (iii) severance, equity acceleration and legal expenses, (iv) transaction and integration expenses, (v) gain (loss) on sale / deconsolidation, (vi) provision for impairment, (vii) other non-core adjustments, net, (viii) noncontrolling interests, (ix) preferred stock dividends, (x) gain on / issuance costs associated with redeemed preferred stock and (xi) net promote. In addition, we believe EBITDA and Adjusted EBITDA are frequently used by securities analysts, investors, and other interested parties in the evaluation of REITs. Because EBITDA and Adjusted EBITDA are calculated before recurring cash charges including interest expense and income taxes, exclude capitalized costs, such as leasing commissions, and are not adjusted for capital expenditures or other recurring cash requirements of our business, their utility as a measure of our performance is limited. Other REITs may calculate EBITDA and Adjusted EBITDA differently than we do and, accordingly, our EBITDA and Adjusted EBITDA may not be comparable to other REITs’ EBITDA and Adjusted EBITDA. Accordingly, EBITDA and Adjusted EBITDA should be considered only as supplements to net income computed in accordance with GAAP as a measure of our financial performance. Net Operating Income (NOI) and Cash NOI: Net operating income, or NOI, represents rental revenue, tenant reimbursement revenue and interconnection revenue less utilities expense, rental property operating expenses, property taxes and insurance expenses (as reflected in the statement of operations). NOI is commonly used by stockholders, company management and industry analysts as a measurement of operating performance of the company’s rental portfolio. Cash NOI is NOI less straight-line rents and above- and below-market rent amortization. Cash NOI is commonly used by stockholders, company management and industry analysts as a measure of property operating performance on a cash basis. Same-Capital Cash NOI represents data centers owned as of December 31, 2024 with less than 5% of total rentable square feet under development and excludes data centers that were undergoing, or were expected to undergo, development activities in 2025-2026, data centers classified as held for sale and contribution, and data centers sold or contributed to joint ventures for all periods presented (prior period numbers adjusted to reflect current same-capital pool). However, because NOI and cash NOI exclude depreciation and amortization and capture neither the changes in the value of our data centers that result from use or market conditions, nor the level of capital expenditures and capitalized leasing commissions necessary to maintain the operating performance of our data centers, all of which have real economic effect and could materially impact our results from operations, the utility of NOI and cash NOI as measures of our performance is limited. Other REITs may calculate NOI and cash NOI differently than we do and, accordingly, our NOI and cash NOI may not be comparable to other REITs’ NOI and cash NOI. NOI and cash NOI should be considered only as supplements to net income computed in accordance with GAAP as measures of our performance.
