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, and Constant-Currency Core FFO per Share are non-GAAP financial measures.

Appendix 4Q25 Financial Results 14

Appendix Management Statements on Non-GAAP Measures 4Q25 Financial Results 15 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 represents net income (loss) (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): We present core funds from operations, or Core FFO, as a supplemental operating measure because, in excluding certain items that do not reflect core revenue or expense streams, it provides a performance measure that, when compared year over year, captures 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) 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. Because certain of these adjustments have a real economic impact on our financial condition and results from operations, the utility of Core FFO as a measure of our performance is limited. Other REITs may calculate Core FFO differently than we do and accordingly, our Core FFO may not be comparable to other REITs’ Core FFO. Core FFO 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, loss on debt extinguishment and modifications, income taxes, 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 and 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, and (x) gain on / issuance costs associated with redeemed preferred stock. Adjusted EBITDA is EBITDA excluding (i) unconsolidated entities real estate related depreciation amortization, (ii) unconsolidated entities interest expense and tax, (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, and (x) gain on / issuance costs associated with redeemed preferred stock. 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. 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. Same–Capital Cash NOI: Same-Capital Cash NOI represents buildings owned as of December 31, 2023 with less than 5% of total rentable square feet under development and excludes buildings that were undergoing, or were expected to undergo, development activities in 2024-2025, buildings classified as held for sale and contribution, and buildings sold or contributed to joint ventures for all periods presented (prior period numbers adjusted to reflect current same-capital pool).

Those risks continue to be relevant to our performance and financial condition. Moreover, we operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time and it is not possible for management to predict all such risk factors, nor can it assess the impact of all such risk factors on the business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.
