What DLR's management wrote with each quarter's results: the press release and, when the company files them, its prepared remarks or the call transcript. The call itself is not filed with SEC, so most quarters have the release only.

In the company's own words

Adjusted vs GAAP earnings per share

Each release

What the company says its adjusted numbers leave out:

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. release Oct 29, 2026

Both numbers are read from the words of each release (usually the highlights), never computed by us; hover a number for its sentence. Quarters where the release gives them only in a table are not shown. The company decides what "adjusted" leaves out; the full reconciliation is in the release.

Note: 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. Please see Non-GAAP Financial Measures in this document for further discussion.

Non-GAAP Financial Measures This document contains non-GAAP financial measures, including FFO, Core FFO, Core FFO (excluding net promote), Constant Currency Core FFO (excluding net promote), 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, a reconciliation from Core FFO (excluding net promote) to Constant Currency Core FFO (excluding net promote), 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, Core FFO (excluding net promote), 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.

Funds From Operations and Core Funds From Financial Supplement Operations Unaudited and in Thousands, Except Per Share Data Third Quarter 2026

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. 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 (2) 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.

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 (3) stock, as applicable, which we consider highly improbable. See above for calculations of FFO and the share count detail section that follows the reconciliation of Core FFO to AFFO for calculations of weighted average common stock and units outstanding. For definitions and discussion of FFO, Core FFO and Core FFO (excluding net promote), see the Definitions section.

Includes development fees included in gains, lease termination fees, (4) gain on sale of equity investment included in other income, insurance proceeds related to property damage and unconsolidated entities non-core adjustments within equity in earnings.

(5) Relates to severance and other charges related to the departure of company executives and integration-related severance.

Includes non-real estate amortization expense, write-offs associated with non-recurring legal and insurance expenses, impact of foreign tax (6) rate changes, non-core adjustments attributable to noncontrolling interests, impact on tax expense due to insurance proceeds related to property damage and adjustments to reflect our proportionate share of transaction costs associated with noncontrolling interests.

Recurring capital expenditures represent non-incremental building improvements required to maintain current revenues, including second-generation tenant improvements and external leasing commissions. (1) Recurring capital expenditures do not include acquisition costs contemplated when underwriting the purchase of a building, costs which are incurred to bring a building up to Digital Realty’s operating standards, or internal leasing commissions.

For a definition and discussion of AFFO, see the Definitions section. (2) For a reconciliation of net income (loss) available to common stockholders to FFO and Core FFO, see above.

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 (3) 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.

Represents the purchase price or sale price, as applicable before (1) contractual price adjustments, transaction expenses, taxes, and potential currency fluctuations. All prices were converted to USD based on FX rate as of September 30, 2026.

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 (2) 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.

Management Statements on Non-GAAP Measures Financial Supplement Unaudited Third Quarter 2026

Definition s 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. 28

Management Statements on Non-GAAP Measures Financial Supplement Unaudited Third Quarter 2026

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. 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 finance 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, 2026, GAAP interest expense was $93 million, capitalized interest was $71 million and preferred stock dividends were $10 million.

  Earnings Release        Third Quarter 2026    
                                                
Non-GAAP Financial Measures This document contains non-GAAP financial measures,
including FFO, Core FFO, Core FFO (excluding net promote), Constant Currency
Core FFO (excluding net promote), 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, a reconciliation from Core FFO (excluding net promote) to Constant
Currency Core FFO (excluding net promote), 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, Core FFO (excluding net promote), 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. Investor Conference Call Prior

       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. 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          
  (2)  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.

       improvements required to maintain current revenues, including            
       second-generation tenant improvements and external leasing commissions.  
  (1)  Recurring capital expenditures do not include acquisition costs          
       contemplated when underwriting the purchase of a building, costs which   
       are incurred to bring a building up to Digital Realty’s operating        
       standards, or internal leasing commissions.

  (3)  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. See above

       Represents the purchase price or sale price, as applicable before        
  (1)  contractual price adjustments, transaction expenses, taxes, and          
       potential currency fluctuations. All prices were converted to USD based  
       on FX rate as of September 30, 2026.                                     
                                                                                
                                                                                
       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  
  (2)  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.

  Management Statements on Non-GAAP Measures    Financial Supplement  
  Unaudited                                     Third Quarter 2026    
                                                                      
Definition s 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. 28

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. 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 finance 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, 2026, GAAP interest expense was $93 million,
capitalized interest was $71 million and preferred stock dividends were $10
million.

The risks included here are not exhaustive, and additional factors could
adversely affect our business and financial performance. Several additional
material risks are discussed in our annual report on Form 10-K for the year
ended December 31, 2025, and other filings with the U.S. Securities and Exchange
Commission. Those risks continue to be relevant to our performance and financial
condition. Moreover, we operate in a 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. We expressly disclaim any
responsibility to update forward-looking statements, whether as a result of new
information, future events or otherwise. Digital Realty, Digital Realty Trust,
