Non-GAAP Financial Measures

This document contains non-GAAP financial measures, including FFO, Core FFO, Adjusted FFO, Net Operating Income (NOI), “Same-Capital” Cash NOI and Adjusted EBITDA. A reconciliation from U.S. GAAP net income available to common stockholders to FFO, a reconciliation from FFO to Core FFO, and definitions of FFO and Core FFO 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.

(2) Certain of Teraco's minority indirect shareholders have the right to put their shares in an upstream parent company of Teraco to Digital Realty in exchange for cash or the equivalent value of shares of Digital Realty common stock, or a combination thereof. US 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 minority interest is added back to the FFO numerator as the denominator assumes all shares have been put back to Digital Realty.

(1) Represents the purchase price before contractual purchase price adjustments, transaction expenses, taxes and potential currency fluctuations.

(2) We calculate the cash capitalization rate on acquisitions, dispositions and joint venture 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.

(3) We estimate the total net rentable square feet available for lease based on a number of factors in addition to contractually leased square feet, including available power, required support space and common area.

(4) Occupancy excludes space under active development and space held for development.

(5) Represents USD to JPY exchange rate as of 3/31/23 of 132.86. Digital Realty's share of the purchase price is $3.6 million.

(6) Teraco acquired a freehold interest of the Cape Town 1 site, a land and building shell, which they had previously leased.

Management Statements on Non-GAAP Measures		Financial Supplement
Unaudited		First Quarter 2023

Definitions

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, or Nareit, in the Nareit Funds From Operations White Paper - 2018 Restatement. FFO represents net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from real estate transactions, impairment of investment in real estate, real estate related depreciation and amortization (excluding amortization of deferred financing costs), unconsolidated JV real estate related depreciation & amortization, non-controlling interests in operating partnership and after adjustments for unconsolidated partnerships and joint ventures. 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 from early extinguishment of debt, (iv) gain on / issuance costs associated with redeemed preferred stock, (v) severance, equity acceleration, and legal expenses, (vi) gain/loss on FX 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 from early extinguishment of debt, 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, unconsolidated joint venture real estate related depreciation & amortization, unconsolidated joint venture interest expense and tax, severance, equity acceleration, and legal expenses, transaction and integration expenses, gain on sale / deconsolidation, impairment of investments in real estate, other non-core adjustments, net, non-controlling interests, preferred stock dividends, including undeclared dividends, and issuance costs associated with redeemed preferred stock. Adjusted EBITDA is EBITDA excluding unconsolidated joint venture real estate related depreciation & amortization, unconsolidated joint venture interest expense and tax, severance, equity acceleration, and legal expenses, transaction and integration expenses, gain on sale / deconsolidation, impairment of investments in real estate, other non-core adjustments, net, non-controlling interests, preferred stock dividends, including undeclared dividends, and 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.

Additional Definitions

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 joint venture debt, less cash and cash equivalents (including Digital Realty’s pro rata share of unconsolidated joint venture cash) divided by the product of Adjusted EBITDA (including Digital Realty’s pro rata share of unconsolidated joint venture EBITDA), multiplied by four.

Debt-plus-preferred-to-total enterprise value is mortgage debt and other loans plus preferred stock divided by mortgage debt and other loans 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, scheduled debt principal payments and preferred dividends. For the quarter ended March 31, 2023, GAAP interest expense was $102 million, capitalized interest was $27 million and scheduled debt principal payments and preferred dividends was $10 million.

Appendix Management Statements on Non-GAAP Measures 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, or NAREIT, in the NAREIT Funds From Operations White Paper - 2018 Restatement. FFO represents net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from real estate transactions, impairment of investment in real estate, real estate related depreciation and amortization (excluding amortization of deferred financing costs), unconsolidated JV real estate related depreciation & amortization, non-controlling interests in operating partnership and after adjustments for unconsolidated partnerships and joint ventures. 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 revenues adjustments, (ii) transaction and integration expenses, (iii) loss from early extinguishment of debt, (iv) gain on / issuance costs associated with redeemed preferred stock, (v) severance, equity acceleration, and legal expenses, (vi) gain/loss on FX 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 from early extinguishment of debt, 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, unconsolidated joint venture real estate related depreciation & amortization, unconsolidated joint venture interest expense and tax, severance, equity acceleration, and legal expenses, transaction and integration expenses, gain on sale / deconsolidation, impairment of investments in real estate, other non-core adjustments, net, non-controlling interests, preferred stock dividends, including undeclared dividends, and issuance costs associated with redeemed preferred stock. Adjusted EBITDA is EBITDA excluding unconsolidated joint venture real estate related depreciation & amortization, unconsolidated joint venture interest expense and tax, severance, equity acceleration, and legal expenses, transaction and integration expenses, gain on sale / deconsolidation, impairment of investments in real estate, other non-core adjustments, net, non-controlling interests, preferred stock dividends, including undeclared dividends, and 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, of the prior year with less than 5% of total rentable square feet under development. Excludes buildings that were undergoing, or were expected to undergo, development activities in 2022-2023, buildings classified as held for sale, and buildings sold or contributed to joint ventures for all periods presented. Prior period numbers adjusted to reflect current same-capital pool. Constant-Currency Same-Capital Cash NOI: We Calculate Constant-Currency Same-Capital Cash NOI by adjusting the Same-Capital Cash NOI for foreign currency translations. 1Q23 Financial Results 17
