General	1. General Organization and Description of Business. ​ The Parent’s only material asset is its ownership of partnership interests of the OP. The Parent generally does not conduct business itself, other than acting as the sole general partner of the OP, issuing public securities from time to time and guaranteeing certain unsecured debt of the OP and certain of its subsidiaries and affiliates. The Parent has not issued any debt but guarantees the unsecured debt of the OP and certain of its subsidiaries and affiliates. ​ The OP holds substantially all the assets of the Company. The OP conducts the operations of the business and has no publicly traded equity. Except for net proceeds from public equity issuances by the Parent, which are generally contributed to the OP in exchange for partnership units, the OP generally generates the capital required by the Company’s business primarily through the OP’s operations, by the OP’s or its affiliates’ direct or indirect incurrence of indebtedness or through the issuance of partnership units. ​ Accounting Principles and Basis of Presentation. The accompanying unaudited interim condensed consolidated financial statements and accompanying notes (the “Financial Statements”) are prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and are presented in our reporting currency, the U.S. dollar. All of the accounts of the Parent, the OP, and the subsidiaries of the OP are included in the accompanying Financial Statements. All material intercompany transactions with consolidated entities have been eliminated. In the opinion of management, the unaudited interim consolidated financial statements reflect all adjustments of a normal recurring nature that are necessary for a fair statement of the results for the interim periods presented. Interim results are not always indicative of results for a full year.

Business Combinations	3. Business Combinations On August 1, 2022, we completed the acquisition of a 61.1% indirect controlling interest in Teraco, a leading carrier-neutral data center and interconnection services provider in South Africa (the “Teraco Acquisition”). The total purchase price was $1.7 billion cash, funded by our Global Revolving Credit Facility and partial settlement of our forward equity sale agreements described under Note 11. “Equity and Capital—Forward Equity Sale.” Teraco controls (and consolidates) the Teraco Connect Trust (“the Trust”) that was created as part of the Broad Based Black Economic Empowerment Program in South Africa. The Trust owns a As of September 30, 2022, the fair values of acquired assets, assumed liabilities and redeemable noncontrolling interests were provisional estimates, based on the best information available. Therefore, these provisional estimates are subject to change as we complete all remaining steps in finalizing the purchase price allocation, and it is reasonably possible there could be significant changes to the preliminary values below. We expect to finalize the valuation of all assets and liabilities by December 31, 2022. The following table summarizes the provisional fair value amounts recorded at the acquisition date (in thousands): ​ ​ ​ ​ ​ ​ ​ Provisional Fair Value ​ ​ Amounts Building and improvements ​ $ 1,376,128 Construction in progress and space held for development ​ ​ 521,153 Operating lease right-of-use assets ​ ​ 2,784 Assumed cash and cash equivalents ​ ​ 5,528 Goodwill ​ 1,625,994 Customer relationship value and other intangibles (weighted-average amortization life of 7 years) ​ 720,126 Debt assumed ​ ​ (355,688) Operating lease liabilities ​ (4,031) Deferred tax liabilities, net ​ ​ (632,841) Redeemable noncontrolling interests ​ ​ (1,530,090) Working capital assets, net ​ ​ 1,112 Total purchase consideration ​ $ 1,730,176 ​ Goodwill ​ Redeemable Noncontrolling Interest (“Redeemable NCI”) — Since the Rollover Shareholders can redeem the put right at their discretion and such redemption, which could be in cash, is outside the Company’s control, the Company recorded the noncontrolling interest as Redeemable NCI and classified it in temporary equity within its condensed consolidated balance sheets. The Redeemable NCI was initially recorded at its acquisition-date fair value and will be adjusted each reporting period for income (or loss) attributable to the noncontrolling interest (a $3.5 million net loss for the period from August 1, 2022 to September 30, 2022). If the contractual redemption value of the Redeemable NCI is greater than its carrying value, an adjustment is made to reflect Redeemable NCI at the higher of its contractual redemption value or its carrying value each reporting period. Changes to the redemption value are recognized immediately in the period the change occurs. If the redemption value of the Redeemable NCI is equal to or less than the fair market value of the Remaining Teraco Interest, the change in the redemption value will be adjusted through Additional Paid in Capital. If the redemption value is greater than the fair market value of the Remaining Teraco Interest, the change in redemption value will be adjusted through Retained Earnings. These adjustments are not reflected on the Company’s income statement, but are instead reflected as adjustments to the net income component of the Company’s earnings per share calculations. When calculating earnings per share attributable to Digital Realty Trust, Inc., the Company adjusts net income attributable to Digital Realty Trust, Inc. to the extent the redemption value exceeds the fair value of the Redeemable NCI on a cumulative basis.

Leases
Leases	4. Leases Lessor Accounting We generate most of our revenue by leasing operating properties to customers under operating lease agreements. We recognize the total minimum lease payments provided for under the leases on a straight-line basis over the lease term if we determine that it is probable that substantially all of the lease payments will be collected over the lease term. Otherwise, rental revenue is recognized based on the amount contractually due. Generally, under the terms of our leases, some of our rental expenses, including common area maintenance, real estate taxes and insurance, are recovered from our customers. We record amounts reimbursed by customers in the period the applicable expenses are incurred, which is generally ratably throughout the term of the lease. Reimbursements are recognized in rental and other services revenue in the condensed consolidated income statements as we are the primary obligor with respect to purchasing and selecting goods and services from third-party vendors and bearing the associated credit risk. Lessee Accounting We lease space at certain of our data centers from third parties and certain equipment under noncancelable lease agreements. Leases for our data centers expire at various dates through 2069. As of September 30, 2022, certain of our data centers, primarily in Europe and Singapore, are subject to ground leases. As of September 30, 2022, the termination dates of these ground leases generally range from 2049 to 2108. In addition, our corporate headquarters along with several regional office locations are subject to leases with termination dates ranging from 2022 to 2028. The leases generally require us to make fixed rental payments that increase at defined intervals during the term of the lease plus pay our share of common area, real estate and utility expenses as incurred. The leases neither contain residual value guarantees nor impose material restrictions or covenants on us. Further, the leases have been classified and accounted for as either operating or finance leases. Rent expense related to operating leases included in rental property operating and maintenance expense in the condensed consolidated income statements was approximately $36.0 million and $36.9 million for the three months ended September 30, 2022 and 2021, respectively, and approximately $109.0 million and $109.9 million for the nine months ended September 30, 2022 and 2021, respectively.

Digital Core REIT owns 10 operating data center properties. The Company’s ownership interest in the units of DCRU, as well as its ownership interest in the operating properties of DCRU are collectively referred to as the Company’s investment in DCREIT. As of September 30, 2022, the Company held 35% of the outstanding DCRU units and separately owned a 10% retained interest in the underlying operating properties. The Company’s 35% interest in DCRU consisted of 392 million units and 390 million units as of September 30, 2022 and December 31, 2021, respectively. Based on the closing price per unit of $0.70 and $1.16 as of September 30, 2022 and December 31, 2021, the fair value of the units the Company owned in DCRU was approximately $274 million and $453 million as of September 30, 2022 and December 31, 2021, respectively. These values do not include the value of the Company’s 10% interest in the operating properties of DCRU, because the associated ownership interests are not publicly traded. The Company accounts for its investment in DCREIT as an equity method investment (and not at fair value) based on the significant influence it is able to exert on DCREIT. The Company determined that the decline in fair value of the investment in DCRU as compared to the Company’s book basis as of September 30, 2022 was temporary in nature. ​ Pursuant to contractual agreements with DCRU and its operating properties, the Company will earn fees for asset and property management services as well as fees for aiding in future acquisition, disposition and development activities. Certain of these fees are payable to the Company in the form of additional units in DCRU or in cash. During the three and nine months ended September 30, 2022, the Company earned fees pursuant to these contractual agreements of approximately $1.8 million and $6.9 million, respectively, which is recorded as fee income and other on the condensed consolidated income statement. ​ Ascenty ​ The debt of our unconsolidated entities generally is non-recourse to us, except for customary exceptions pertaining to matters such as intentional misuse of funds, environmental conditions, and material misrepresentations. ​

Early Extinguishment of Unsecured Senior Notes We recognized the following losses on early extinguishment of unsecured notes: ● During the nine months ended September 30, 2022 : $51.1 million primarily due to redemption of the 4.750% Notes due 2025 in February 2022. ● During the nine months ended September 30, 2021 : $18.3 million primarily due to redemption of the 2.750% Notes due 2023 in February 2021. ​ Global Revolving Credit Facility Amendment ​ On April 5, 2022, the Operating Partnership entered into an amendment (the “Amendment”) to the Second Amended and Restated Global Senior Credit Agreement (the “Credit Agreement”) The Amendment provides for, among other things: (1) an increase in the size of the global revolving credit facility from $3.0 billion to $3.75 billion and (2) the transition from U.S. dollar London Interbank Offered Rate (LIBOR) to Term Secured Overnight Financing Rate (SOFR) for floating rate borrowings denominated in U.S. dollars for all purposes under the Credit Agreement. ​ Euro Term Loan Agreement ​ On August 11, 2022, Digital Dutch Finco B.V., a wholly owned subsidiary of the Operating Partnership, entered into a term loan agreement (the “Euro Term Loan Agreement”) which governs (i) a €375.0 million three-year senior unsecured term loan facility (the “2025 Term Facility”), the entire amount of which was funded on the closing date, and (ii) a €375.0 million five-year senior unsecured term loan facility (the “2025-27 Term Facility” and, together with the 2025 Term Facility, the “Euro Term Facilities”), comprised of €125.0 million of initial term loans, the entire amount of which was funded on the closing date, and €250.0 million of delayed draw term loan commitments that were not funded on the closing date, and were funded on September 9, 2022. The Euro Term Facilities provide for borrowings in Euros. The 2025 Term Facility matures on August 11, 2025. The 2025-27 Term Facility matures on August 11, 2025, subject to two maturity extension options of one year each. The interest rate for borrowings under the Euro Term Facilities is based on EURIBO, plus a margin based on the corporate credit rating of our long-term senior unsecured debt of between 0.80% and 1.60% per annum. As of the closing date, the applicable rate for borrowings is EURIBO plus 0.95% per annum. We are also required to pay certain fees to the administrative agent under the Euro Term Facilities. The Euro Term Facilities may be voluntarily prepaid in whole or in part at any time without premium or penalty. Amounts borrowed under the Euro Term Facilities and repaid or prepaid may not be reborrowed. ​ 5.550% Notes due 2028 ​ On September 27, 2022, Digital Realty Trust, L.P. completed an underwritten public offering of $550.0 million aggregate principal amount of its 5.550% Notes due 2028.

Equity and Capital	11. Equity and Capital Equity Distribution Agreement Digital Realty Trust, Inc. and Digital Realty Trust, L.P. are parties to an at-the-market (ATM) equity offering sales agreement dated April 1, 2022 (the “Sales Agreement”). Pursuant to the Sales Agreement, Digital Realty Trust, Inc. can issue and sell common stock having an aggregate offering price of up to $1.5 billion through various named agents from time to time. For the nine months ended September 30, 2022, we had no sales under the Sales Agreement and $1.5 billion is still available. Forward Equity Sale On September 13, 2021, Digital Realty Trust, Inc. completed an underwritten public offering of 6,250,000 shares of its common stock, all of which were offered in connection with forward sale agreements it entered into with certain financial institutions acting as forward purchasers. The forward purchasers borrowed and sold an aggregate of 6,250,000 shares of Digital Realty Trust, Inc.’s common stock in the public offering. Digital Realty Trust, Inc. did not receive any proceeds from the sale of our common stock by the forward purchasers in the public offering. The Company may receive gross proceeds of approximately $1.0 billion (based on the offering price of $155.69 per share) upon full physical settlement of the forward sale agreements, which is to be no later than March 13, 2023. During the three months ended September 30, 2022, we partially settled the forward sale agreements by issuing approximately 2.7 million shares, resulting in proceeds of approximately $400.0 million. Upon physical settlement of the forward sale agreements , the Operating Partnership is expected to issue general partner common partnership units to Digital Realty Trust, Inc. in exchange for contribution of the net proceeds. We account for our forward equity sales agreements in accordance with the accounting guidance governing financial instruments and derivatives. As of September 30, 2022, none of our forward equity sales agreements were deemed to be liabilities as they did not embody obligations to repurchase our shares, nor did they embody obligations to issue a variable number of shares for which the monetary value was predominantly fixed, varied with something other than the fair value of our shares, or varied inversely in relation to our shares. We also evaluated whether the agreements met the derivatives and hedging guidance scope exception to be accounted for as equity instruments and concluded that the agreements could be classified as equity contracts based on the following assessment: (i) none of the agreements’ exercise contingencies were based on observable markets or indices besides those related to the market for our own stock price and operations; and (ii) none of the settlement provisions precluded the agreements from being indexed to our own stock. Noncontrolling Interests in Operating Partnership ​ Noncontrolling interests in the Operating Partnership relate to the proportion of entities consolidated by the Company that are owned by third parties. The following table shows the ownership interest in the Operating Partnership as of September 30, 2022 and December 31, 2021 (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2022 ​ December 31, 2021 ​ ​ Number of ​ Percentage of ​ Number of ​ Percentage of ​ units total ​ units total Digital Realty Trust, Inc. ​ 287,509 ​ 97.9 % ​ 284,415 ​ 98.0 % Noncontrolling interests consist of: ​ ​ ​ ​ Common units held by third parties 4,387 1.5 % ​ 4,389 1.5 % Incentive units held by employees and directors (see Note 13 "Incentive Plan") 1,908 0.6 % ​ 1,543 0.5 % ​ 293,804 100.0 % ​ 290,347 100.0 % ​ Limited partners have the right to require the Operating Partnership to redeem all or a portion of their common units for cash based on the fair market value of an equivalent number of shares of Digital Realty Trust, Inc. common stock at the time of redemption.

The common units and incentive units of the Operating Partnership are classified within equity, except for certain common units issued to certain former DuPont Fabros Technology, L.P. unitholders in the Company’s acquisition of DuPont Fabros Technology, Inc., which are subject to certain restrictions and, accordingly, are not presented as permanent equity in the condensed balance sheet. The redemption value of the noncontrolling Operating Partnership common units and the vested incentive units was approximately $585.1 million and $1,074.7 million based on the closing market price of Digital Realty Trust, Inc. common stock on September 30, 2022 and December 31, 2021, respectively.

Incentive Plans	13. Incentive Plans 2014 Incentive Award Plan The Company provides incentive awards in the form of common stock or awards convertible into common stock pursuant to the Digital Realty Trust, Inc., Digital Services, Inc. and Digital Realty Trust, L.P. 2014 Incentive Award Plan, as amended (the “Incentive Plan”). The major categories of awards that can be issued under the Incentive Plan include: Long-Term Incentive Units (“LTIP Units”) two Service-Based Restricted Stock Units two Performance-Based Awards (“the Performance Awards”) vest is determined based on either a market performance criterion (“Market-Based Performance Awards”) or financial performance criterion (“Financial-Based Performance Awards”). Market-Based Performance Awards. The percentage of the total number of units that performance vest for Market-Based Performance Awards is determined by comparing the Company’s total shareholder return (“TSR”) relative to the MSCI US REIT Index (“RMS”) over a three-year period. The awards then have a time-based vesting element that allows for 50% of the performance-vested units to fully vest in the immediately following year and 50% of the performance-vested units to fully vest in the next-subsequent year. The fair value of these awards is determined using a Monte Carlo simulation to estimate the probability of the market vesting condition being satisfied. Achievement of the market performance condition is measured based on the difference between Digital Realty Trust, Inc.’s TSR percentage and the TSR percentage of the RMS as is shown in the subsequent table (the “RMS Relative Market Performance”). ​ ​ ​ ​ ​ ​ ​ ​ ​ Market ​ 2021-2022 ​ Performance ​ RMS Relative ​ Vesting Level Market Performance ​ Percentage Below Threshold Level ≤ -500 basis points ​ 0 % Threshold Level -500 basis points ​ 25 % Target Level 0 basis points ​ 50 % High Level ≥ 500 basis points ​ 100 % ​ If the RMS Relative Market Performance falls between the levels specified in the above table, the percentage of the award that will vest with respect to the market condition will be determined using straight-line linear interpolation between such levels. ​ 2019 Awards Following the completion of the applicable Market Performance Period, in January 2022, the Compensation Committee made the following determinations regarding the vesting of these awards: ● The RMS Relative Market Performance fell between the target and high levels for the 2019 awards and accordingly, 239,436 Class D units and 70,721 Restricted Stock Units performance vested and qualified for time-based vesting. ● The number of performance-vested Class D units included 18,966 distribution equivalent units that immediately vested on December 31, 2021. ● On February 27, 2022, 50% of the 2019 awards vested and the remaining 50% will vest on February 27, 2023, subject to continued employment through the applicable vesting date. The grant date fair value of the Market-Based Performance Awards was approximately $12.3 million and $25.0 million for the nine months ended September 30, 2022 and 2021, respectively. This amount will be recognized as compensation expense on a straight-line basis over the expected service period of approximately four years. ​ Financial-Based Performance Awards. On March 4, 2022, the Company granted Financial-Based Performance Awards, based on growth in core funds from operation (“Core FFO”) during the three-year period commencing on January 1, 2022. The awards have a time-based vesting element consistent with the Market-Based Performance Awards discussed above. For these awards, fair value is based on market value on the date of grant and compensation cost is recognized based on the probable achievement of the performance condition at each reporting period. The grant date fair value of these awards is ​ Other Items two As of September 30, 2022, approximately 5.0 million shares of common stock, including awards that can be converted to or exchanged for shares of common stock, remained available for future issuance under the Incentive Plan. Each LTIP unit and each Class D unit issued under the Incentive Plan counts as one share of common stock for purposes of calculating the limit on shares that may be issued under the Incentive Plan and the individual award limits set forth therein.

Derivative Instruments Derivatives Designated as Hedging Instruments ​ Net Investment Hedges ​ In September 2022, we entered into cross-currency interest rate swaps, which effectively convert a portion of our U.S. dollar-denominated fixed-rate debt to foreign currency-denominated fixed-rate debt in order to hedge the currency exposure associated with our net investment in foreign subsidiaries. As of September 30, 2022, we had cross-currency interest rate swaps outstanding with notional amounts of $1.55 billion and maturity dates ranging through 2028.

Fair Value of Financial Instruments	15. Fair Value of Financial Instruments There have been no significant changes in our policy for fair value measurements from what was disclosed in our 2021 Form 10-K. As of September 30, 2022 and December 31, 2021, the carrying amounts for cash and cash equivalents, restricted cash, accounts and other receivables, accounts payable and other accrued liabilities, accrued dividends and distributions, security deposits and prepaid rents approximate fair value because of the short-term nature of these instruments. The carrying value of our Global Revolving Credit Facilities approximates estimated fair value, because these liabilities have variable interest rates and our credit ratings have remained stable. Differences between the carrying value and fair value of our unsecured senior notes and secured and other debt are caused by differences in interest rates or borrowing spreads that were available to us on September 30, 2022 and December 31, 2021 as compared to those in effect when the debt was issued or assumed. We calculate the fair value of our secured and other debt and unsecured senior notes based on currently available market rates assuming the loans are outstanding through maturity and considering the collateral and other loan terms. In determining the current market rate for fixed rate debt, a market spread is added to the quoted yields on federal government treasury securities with similar maturity dates to our debt.
