A reconciliation from U.S. GAAP net income available to common stockholders to FFO, a reconciliation from FFO to Core FFO, a reconciliation from Core FFO to Adjusted FFO, a reconciliation from NOI to Cash NOI, and definitions of FFO, Core FFO, Constant Currency Core FFO, Adjusted FFO, NOI and “Same-Capital” Cash NOI are included as an attachment to this document. A reconciliation from U.S. GAAP net income available to common stockholders to Adjusted EBITDA, a definition of Adjusted EBITDA and definitions of net debt-to-Adjusted EBITDA, debt-plus-preferred-to-total enterprise value, cash NOI, and fixed charge coverage ratio are included as an attachment to this document. The company does not provide a reconciliation for non-GAAP estimates on a forward-looking basis, where 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.

U.S. GAAP requires Digital Realty to assume the put right is settled in shares for purposes of calculating diluted EPS. This same approach was utilized to calculate FFO/share. The potential future dilutive impact associated with this put right will be excluded from Core FFO and AFFO until settlement occurs – causing diluted share count to be higher for FFO than for Core FFO and AFFO. When calculating diluted FFO, Teraco related noncontrolling interest is added back to the FFO numerator as the denominator assumes all shares have been put back to Digital Realty. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ Nine Months Ended ​ ​ ​ 30-Sep-25 ​ ​ 30-Jun-25 ​ ​ 31-Mar-25 ​ ​ 31-Dec-24 ​ ​ 30-Sep-24 ​ ​ ​ 30-Sep-25 ​ ​ 30-Sep-24 Teraco noncontrolling share of FFO ​ ​ $17,018 ​ ​ $15,850 ​ ​ $13,286 ​ ​ $14,905 ​ ​ $9,828 ​ ​ ​ $46,154 ​ ​ $32,049 Teraco related minority interest ​ ​ $17,018 ​ ​ $15,850 ​ ​ $13,286 ​ ​ $14,905 ​ ​ $9,828 ​ ​ ​ $46,154 ​ ​ $32,049 ​ (3) For all periods presented, we have excluded the effect of dilutive series J, series K and series L preferred stock, as applicable, that may be converted into common stock upon the occurrence of specified change in control transactions as described in the articles supplementary governing the series J, series K and series L preferred stock, as applicable, which we consider highly improbable.

All prices were converted to USD based on FX rate as of September 30, 2025. (2) We calculate the cash capitalization rate on acquisitions, dispositions, and joint venture and fund contributions by dividing anticipated annual net operating income by the purchase/sale/contribution price, including assumed debt and related pre-payment penalties. Net operating income represents rental revenue and tenant reimbursement revenue from in-place leases, less rental property operating and maintenance expenses, property taxes and insurance expenses, and is not a financial measure calculated in accordance with GAAP. We caution you not to place undue reliance on our cash capitalization rates because they are based solely on data made available to us in the diligence process in connection with the relevant acquisitions and are calculated on a non-GAAP basis. Our calculation of the cash capitalization rate on acquisitions may change, based on our experience operating the data centers subsequent to closing of the acquisitions. In addition, the actual cash capitalization rates may differ from our expectations based on numerous other factors, including the results of our final purchase price allocation, difficulties collecting anticipated rental revenues, tenant bankruptcies, property tax reassessments and unanticipated expenses at the data centers that we cannot pass on to tenants.

FFO is a non-GAAP financial measure and 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. 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, 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 & 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. 31 Table of Contents Management Statements on Non-GAAP Measures Financial Supplement Unaudited ​ Third Quarter 2025 ​ 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 buildings owned as of December 31, 2023 of the prior year 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). 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. Additional Definitions GAAP refers to United States generally accepted accounting principles. Net debt-to-Adjusted EBITDA ratio is calculated as total debt at balance sheet carrying value, plus capital lease obligations, plus Digital Realty’s pro rata share of unconsolidated entities debt, less cash and cash equivalents (including Digital Realty’s pro rata share of unconsolidated entities cash) divided by the product of Adjusted EBITDA (including Digital Realty’s pro rata share of unconsolidated entities EBITDA), multiplied by four. Debt-plus-preferred-to-total enterprise value is total debt plus preferred stock divided by total debt plus the liquidation value of preferred stock and the market value of outstanding Digital Realty Trust, Inc. common stock and Digital Realty Trust, L.P. units, assuming the redemption of Digital Realty Trust, L.P. units for shares of Digital Realty Trust, Inc. common stock. Fixed charge coverage ratio is Adjusted EBITDA divided by the sum of GAAP interest expense, capitalized interest and preferred stock dividends. For the quarter ended September 30, 2025, GAAP interest expense was $114 million, capitalized interest was $33 million and preferred stock dividends were $10 million. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Reconciliation of Net Operating Income (NOI) ​ Three Months Ended ​ ​ Nine Months Ended (in thousands)      30-Sep-25      30-Jun-25      30-Sep-24       30-Sep-25      30-Sep-24 ​ ​   ​ ​   ​ ​   ​ ​ ​   ​ ​   ​ Operating income ​ ​ $138,421 ​ ​ $211,697 ​ ​ $168,286 ​ ​ ​ $545,868 ​ ​ $327,542 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​  Fee income ​ ​ (36,398) ​ ​ (34,427) ​ ​ (12,907) ​ ​ ​ (91,468) ​ ​ (41,572)  Other income ​ ​ (4,746) ​ ​ (1,363) ​ ​ (4,581) ​ ​ ​ (6,242) ​ ​ (7,568)  Depreciation and amortization ​ ​ 497,002 ​ ​ 461,167 ​ ​ 459,997 ​ ​ ​ 1,401,178 ​ ​ 1,316,442  General and administrative ​ ​ 139,911 ​ ​ 133,755 ​ ​ 115,120 ​ ​ ​ 394,778 ​ ​ 349,051 Severance, equity acceleration and legal expenses ​ ​ 1,794 ​ ​ 2,262 ​ ​ 2,481 ​ ​ ​ 6,484 ​ ​ 4,156 Transaction and integration expenses ​ ​ 86,559 ​ ​ 22,546 ​ ​ 24,194 ​ ​ ​ 149,007 ​ ​ 82,105 Provision for impairment ​ ​ — ​ ​ — ​ ​ — ​ ​ ​ — ​ ​ 168,303 Other expenses ​ ​ 3,297 ​ ​ 195 ​ ​ 4,774 ​ ​ ​ 3,604 ​ ​ 15,080 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net Operating Income ​ ​ $825,840 ​ ​ $795,832 ​ ​ $757,365 ​ ​ ​ $2,403,209 ​ ​ $2,213,540 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​  Cash Net Operating Income (Cash NOI) ​ ​    ​ ​    ​ ​    ​ ​ ​    ​ ​    ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net Operating Income ​ ​ $825,840 ​ ​ $795,832 ​ ​ $757,365 ​ ​ ​ $2,403,209 ​ ​ $2,213,540 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​  Straight-line rental revenue ​ ​ (33,196) ​ ​ (24,015) ​ ​ (18,423) ​ ​ ​ (66,904) ​ ​ (23,818)  Straight-line rental expense ​ ​ (297) ​ ​ (469) ​ ​ 1,683 ​ ​ ​ (742) ​ ​ 4,011  Above- and below-market rent amortization ​ ​ (864) ​ ​ (752) ​ ​ (742) ​ ​ ​ (2,322) ​ ​ (3,287) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash Net Operating Income ​ ​ $791,483 ​ ​ $770,596 ​ ​ $739,883 ​ ​ ​ $2,333,241 ​ ​ $2,190,446 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Constant Currency CFFO Reconciliation ​ Three Months Ended ​ ​ Nine Months Ended (in thousands, except per share data)      30-Sep-25      ​      30-Sep-24       30-Sep-25      30-Sep-24 ​ ​   ​ ​   ​ ​   ​ ​ ​   ​ ​   ​ Core FFO (1) ​ ​ $656,001 ​ ​ ​ ​ ​ $557,744 ​ ​ ​ $1,907,639 ​ ​ $1,628,377 Core FFO impact of holding '24 Exchange Rates Constant (2) ​ ​ (11,062) ​ ​ ​ ​ ​ — ​ ​ ​ (17,348) ​ ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Constant Currency Core FFO ​ ​ $644,939 ​ ​ ​ ​ ​ $557,744 ​ ​ ​ $1,890,291 ​ ​ $1,628,377 Weighted-average shares and units outstanding - diluted ​ ​ 347,700 ​ ​ ​ ​ ​ 334,476 ​ ​ ​ 344,873 ​ ​ 326,545 Constant Currency CFFO Per Share ​ ​ $1.85 ​ ​ ​ ​ ​ $1.67 ​ ​ ​ $5.48 ​ ​ $4.99 ​ ​ 1) As reconciled to net income above. 2) Adjustment calculated by holding currency translation rates for 2025 constant with average currency translation rates that were applicable to the same periods in 2024 . ​ ​ 32 Table of Contents Forward-Looking Statements Financial Supplement ​ ​ Third Quarter 2025 ​ ​ This document contains forward-looking statements within the meaning of the federal securities laws, which are based on current expectations, forecasts and assumptions that involve risks and uncertainties that could cause actual outcomes and results to differ materially.
