EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the quarter ended March 31, 2023 of Digital Realty Trust, Inc., a Maryland corporation, and Digital Realty Trust, L.P., a Maryland limited partnership, of which Digital Realty Trust, Inc. is the sole general partner. Unless otherwise indicated or unless the context requires otherwise, all references in this report to “we,” “us,” “our,” “our Company”, or “the Company” refer to Digital Realty Trust, Inc. together with its consolidated subsidiaries, including Digital Realty Trust, L.P. In statements regarding qualification as a REIT, such terms refer solely to Digital Realty Trust, Inc. Unless otherwise indicated or unless the context requires otherwise, all references to the “Parent” refer to Digital Realty Trust, Inc., and all references to “our Operating Partnership,” “the Operating Partnership” or “the OP” refer to Digital Realty Trust, L.P. together with its consolidated subsidiaries.

The Parent is a real estate investment trust, or REIT, and the sole general partner of the OP. As of March 31, 2023, the Parent owned an approximate 97.8% common general partnership interest in Digital Realty Trust, L.P. The remaining approximate 2.2% of the common limited partnership interests of Digital Realty Trust, L.P. are owned by non-affiliated third parties and certain directors and officers of the Parent. As of March 31, 2023, the Parent owned all of the preferred limited partnership interests of Digital Realty Trust, L.P. As the sole general partner of Digital Realty Trust, L.P., the Parent has the full, exclusive and complete responsibility for the OP’s day-to-day management and control.

We believe combining the quarterly reports on Form 10-Q of the Parent and the OP into this single report results in the following benefits:

| ● | enhancing investors’ understanding of the Parent and the OP by enabling investors to view the business as a whole in the same manner as management views and operates the business;

| ● | eliminating duplicative disclosure and providing a more streamlined and readable presentation since a substantial portion of the disclosure applies to both the Parent and the OP; and

| ● | creating time and cost efficiencies through the preparation of one combined report instead of two separate reports.

It is important to understand the few differences between the Parent and the OP in the context of how we operate the Company. The Parent does not conduct business itself, other than acting as the sole general partner of the OP and issuing public equity from time to time and guaranteeing certain unsecured debt of the OP and certain of its subsidiaries and affiliates. The OP holds substantially all the assets of the business, directly or indirectly. The OP conducts the operations of the business and is structured as a partnership with no publicly traded equity. Except for net proceeds from equity issuances by the Parent, which are generally contributed to the OP in exchange for partnership units, the OP generates capital required by the business through the OP’s operations, incurrence of indebtedness and issuance of partnership units to third parties.

The presentation of noncontrolling interests, stockholders’ equity and partners’ capital are the main areas of difference between the consolidated financial statements of the Parent and those of the OP. The differences in the presentations between stockholders’ equity and partners’ capital result from the differences in the equity and capital issuances in the Parent and in the OP.

To highlight the differences between the Parent and the OP, separate sections in this report, as applicable, individually discuss the Parent and the OP, including separate financial statements and separate Exhibit 31 and 32 certifications. In the sections that combine disclosure of the Parent and the OP, this report refers to actions or holdings as being actions or holdings of the Company.

As general partner with control of the OP, the Parent consolidates the OP for financial reporting purposes, and it does not have significant assets other than its investment in the OP. Therefore, the assets and liabilities of the Parent and the OP are the same on their respective condensed consolidated financial statements. The separate discussions of the Parent and the OP in this report should be read in conjunction with each other to understand the results of the Company on a consolidated basis and how management operates the Company.

1. General

Organization and Description of Business. Digital Realty Trust, Inc. (the Parent), through its controlling interest in Digital Realty Trust, L.P. (the Operating Partnership or the OP) and the subsidiaries of the OP (collectively, we, our, us or the Company), is a leading global provider of data center (including colocation and interconnection) solutions for customers across a variety of industry verticals ranging from cloud and information technology services, social networking and communications to financial services, manufacturing, energy, healthcare, and consumer products. The OP, a Maryland limited partnership, is the entity through which the Parent, a Maryland corporation, conducts its business of owning, acquiring, developing and operating data centers. The Parent operates as a REIT for U.S. federal income tax purposes.

​

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. The information included in this Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2022 (“2022 Form 10-K”), as filed with the U.S. Securities and Exchange Commission (“SEC”) and other filings with the SEC.

​

Management Estimates and Assumptions. U.S. GAAP requires us to make estimates and assumptions that affect reported amounts of revenue and expenses during the reporting period, reported amounts for assets and liabilities as of the date of the financial statements, and disclosures of contingent assets and liabilities as of the date of the financial statements. Although we believe the estimates and assumptions we made are reasonable and appropriate, as discussed in the applicable sections throughout the consolidated financial statements, different assumptions and estimates could materially impact our reported results. Actual results and outcomes may differ from our assumptions.

​

New Accounting Pronouncements. Recently issued accounting pronouncements that have yet to be adopted by the Company are not expected to have a material impact to the condensed consolidated financial statements.

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 12% interest in Teraco’s primary operating company, however, because Teraco (and the Company) controls the Trust, the Trust is consolidated by Teraco (and the Company). If the Trust was not consolidated by Teraco, the Company’s ownership interest in Teraco would be approximately 55%.

Goodwill — The purchase price of the Teraco Acquisition exceeded the fair value of net tangible and intangible assets acquired and liabilities assumed by $1.6 billion. This amount was recorded as goodwill. We believe the strategic benefits of the acquisition support the value of goodwill recorded. Specifically, Teraco has numerous cross-connects, cloud on-ramps and data centers in addition to direct access to multiple subsea cables. The acquisition of Teraco added South Africa to the Company’s existing markets on the continent, including in Kenya, Mozambique, and Nigeria. The strategic importance of these markets has been enhanced by the recent and ongoing implementation of new subsea cable networks encircling Africa. When combined with the Company’s highly connected facilities in Marseille, France, and across EMEA, our customers now have a range of strategic connectivity hubs from which to serve all corners of the African market.

​

Redeemable Noncontrolling Interest (“Redeemable NCI”) — As part of the Teraco Acquisition, the Company and certain of its subsidiaries entered into a put/call agreement with the owners of the interest in Teraco that was not acquired by the Company (the “Put/Call Agreement”). The interest retained by these owners is hereafter referred to as the “Remaining Teraco Interest” and the owners of such interest are hereafter referred to as the “Rollover Shareholders”. Pursuant to the Put/Call Agreement, the Rollover Shareholders have the right to sell all or a portion of the Remaining Teraco Interest to the Company for a two-year period beginning on February 1, 2026, and the Company has the right to purchase all or a portion of the Remaining Teraco Interest from the Rollover Shareholders for a one-year period beginning on February 1, 2028. Per the terms of the agreement, the purchase price of the Remaining Teraco Interest for the put right and the call right can be settled by the Company with cash, shares in the Company, or a combination of cash and shares. In the event the Company elects to settle a put or call in whole or in part with shares of Digital Realty Trust, Inc.’s common stock, such shares will be issued in a private placement transaction with customary accompanying registration rights.

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 $2.3 million net loss for the three months ended March 31, 2023). 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. For the three months ended March 31, 2023, no such adjustment was required.

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 March 31, 2023, certain of our data centers, primarily in Europe and Singapore, are subject to ground leases. As of March 31, 2023, the termination dates of these ground leases generally range from 2027 to 2108. In addition, our corporate headquarters along with several regional office locations are subject to leases with termination dates ranging from 2023 to 2041. 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 $38.4 million and $37.4 million for the three months ended March 31, 2023 and 2022, respectively.

Deferred Rent Receivables

​

Deferred rent receivables represent rental income that has been recognized as revenue under ASC 842, but which is not yet due from customers under their existing rental agreements.

(1) | During the three months ended March 31, 2023, we derecognized all assets, liabilities and 50% noncontrolling interests related to a joint venture that was previously consolidated and recognized an equity method investment of approximately $61.9 million based on the value of our 50% noncontrolling interest in the joint venture. We had concluded that we would consolidate the joint venture during the development phase of the buildings because we had the power to direct activities that most significantly impacted the joint venture’s economic performance, however, upon the building’s completion and commencing the operational phase, we no longer have the power to direct the activities that most significantly impact the joint venture’s economic performance and deconsolidated the joint venture and recognized the investment under the equity method as we still retained significant influence.

​

DCREIT – Digital Core REIT is a standalone real estate investment trust formed under Singapore law, which is publicly-traded on the Singapore Exchange under the ticker symbol “DCRU”. Digital Core REIT owns 11 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 March 31, 2023, the Company held 35% of the outstanding DCRU units and separately owned a 10% direct retained interest in the underlying North American operating properties and a 75% direct retained interest in the underlying German operating property.

​

The Company’s 35% interest in DCRU consisted of 399 million units and 396 million units as of March 31, 2023 and December 31, 2022, respectively. Based on the closing price per unit of $0.445 and $0.55 as of March 31, 2023 and December 31, 2022, respectively, the fair value of the units the Company owned in DCRU was approximately $178 million and $218 million as of March 31, 2023 and December 31, 2022, respectively.

​

These values do not include the value of the Company’s 10% interest in the North American operating properties and 75% interest in the German operating property 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 March 31, 2023 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 months ended March 31, 2023 and 2022, the Company earned fees pursuant to these contractual agreements of approximately $2.3 million, which is recorded as fee income and other on the condensed consolidated income statement.

​

Ascenty – The Company’s ownership interest in Ascenty includes an approximate 2% interest held by one of the Company’s non-controlling interest holders. This 2% interest had a carrying value of approximately $16 million and $18 million as of March 31, 2023 and December 31, 2022, respectively. Ascenty is a variable interest entity (“VIE”) and the Company’s maximum exposure to loss related to this VIE is limited to our equity investment in the entity.

​

Debt – 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.

​

7. Goodwill

Goodwill represents the excess of the purchase price over the fair value of net tangible and intangible assets acquired in a business combination. Changes in the value of goodwill at March 31, 2023 as compared to December 31, 2022 were primarily driven by changes in exchange rates associated with goodwill balances denominated in foreign currencies.

​

All debt is currently held by the OP or its consolidated subsidiaries, and the Parent is the guarantor or co-guarantor of the Global Revolving Credit Facility and the Yen Revolving Credit Facility (together, referred to as the “Global Revolving Credit Facilities”), the unsecured term loans and the unsecured senior notes. A summary of outstanding indebtedness is as follows (in thousands):

The Term Loan Facility will mature on March 31, 2025, subject to one twelve-month extension option at the Operating Partnership’s option; provided, that the Operating Partnership must pay a 0.1875% extension fee based on the then-outstanding principal amount of the term loans under the Term Loan Facility.

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. Alternatively, Digital Realty Trust, Inc. may elect to acquire those common units in exchange for shares of its common stock on a one-for-one basis, subject to adjustment in the event of stock splits, stock dividends, issuance of stock rights, specified extraordinary distributions and similar events. 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 $614.4 million and $591.2 million based on the closing market price of Digital Realty Trust, Inc. common stock on March 31, 2023 and December 31, 2022, respectively.

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”): LTIP Units, in the form of profits interest units of the Operating Partnership, may be issued to eligible participants for the performance of services to or for the benefit of the Operating Partnership. LTIP Units (other than Class D units), whether vested or not, receive the same quarterly per-unit distributions as Operating Partnership common units. Initially, LTIP Units do not have full parity with common units with respect to liquidating distributions. However, if such parity is reached, vested LTIP Units may be converted into an equal number of common units of the Operating Partnership at any time. The awards generally vest over periods between two and four years.

Service-Based Restricted Stock Units: Service-based Restricted Stock Units, which vest over periods between two and four years, convert to shares of Digital Realty Trust, Inc.’s common stock upon vesting.

Performance-Based Awards (“the Performance Awards”): Performance-based Class D units of the Operating Partnership and performance-based Restricted Stock Units of Digital Realty Trust, Inc.’s common stock may be issued to officers and employees of the Company. The Performance Awards include performance-based and time-based vesting criteria. Depending on the type of award, the total number of units that qualify to fully vest is determined based on either a market performance criterion (“Market-Based Performance Awards”) or financial performance criterion (“Financial-Based Performance Awards”), in each case, subject to time-based vesting.

Market-Based Performance Awards.

The market performance criterion compares Digital Realty Trust, Inc.’s total shareholder return (“TSR”) relative to the MSCI US REIT Index (“RMS”) over a three-year performance period (“Market Performance Period”), subject to continued service, in order to determine the percentage of the total eligible pool of units that qualifies to be awarded. Following the completion of the Market Performance Period, the awards then have a time-based vesting element pursuant to which 50% of the performance-vested units fully vest in the February immediately following the end of the Market Performance Period and 50% of the performance-vested units fully vest in the subsequent February.

Vesting with respect to the market 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
​ | ​ | ​ | 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.

​

2020 Awards

| ● | In January 2023, the RMS Relative Market Performance fell between the threshold and target levels for the 2020 awards and, accordingly, 72,230 Class D units and 7,083 Restricted Stock Units performance vested and qualified for time-based vesting.

| ● | The Class D units included 5,841 distribution equivalent units that immediately vested on December 31, 2022.

| ● | On February 27, 2023, 50% of the 2020 awards vested and the remaining 50% will vest on February 27, 2024, subject to continued employment through the applicable vesting date. ​

The grant date fair value of the Market-Based Performance Awards was approximately $8.2 million and $12.3 million for the three months ended March 31, 2023 and 2022, 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 $12.3 million, based on Digital Realty Trust, Inc.’s closing stock price at the grant date.

​

Other Items: In addition to the LTIP Units, service-based Restricted Stock Units and Performance Awards described above, one-time grants of time and/or performance-based Class D units and Restricted Stock Units were issued in connection with the Company’s combination with InterXion Holding N.V. These awards vest over a period of two and three years based on continued service and/or the attainment of performance metrics related to successful integration of the Interxion business.

As of March 31, 2023, approximately 4.3 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.

14. 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 March 31, 2023, we had cross-currency interest rate swaps outstanding with notional amounts of $1.55 billion and maturity dates ranging through 2028.

​

The effect of these net investment hedges on accumulated other comprehensive income and the condensed consolidated income statements for the three months ended March 31, 2023 and 2022 was as follows (in thousands):

Cash Flow Hedges

​

We had no material outstanding derivatives designated as cash flow hedges as of March 31, 2023. Amounts reported in accumulated other comprehensive loss related to interest rate swaps are reclassified to interest expense as interest payments are made on our debt. As of March 31, 2023, we had no material interest rate swap agreements outstanding.

(1) | As presented in our condensed consolidated balance sheets within other assets.

(2) | As presented in our condensed consolidated balance sheets within accounts payable and other accrued liabilities.

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 2022 Form 10-K.

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 and unsecured term loans 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 March 31, 2023 and December 31, 2022 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.

​

16. Commitments and Contingencies

Our properties require periodic investments of capital for tenant-related capital expenditures and for general capital improvements including ground up construction. From time to time in the normal course of our business, we enter into various construction contracts with third parties that may obligate us to make payments. At March 31, 2023, we had open commitments, including amounts reimbursable by customers of approximately $30.6 million, related to construction contracts of approximately $2.6 billion.

In the ordinary course of our business, we may become subject to various legal proceedings. As of March 31, 2023, we were not a party to any legal proceedings which we believe would have a material adverse effect on our operations or financial position.

18. Segment and Geographic Information

​

A majority of the Company’s largest customers are global entities that transact with the Company across multiple geographies worldwide. In order to better address the needs of these global customers, the Company manages critical decisions around development, operations, and leasing globally based on customer demand considerations. In this regard, the Company manages customer relationships on a global basis in order to achieve consistent sales and delivery experience of our products for our customers throughout the global portfolio. In order to best accommodate the needs of global customers (and customers that might one day become global), the Company manages its operations as a single global business – with one operating segment and therefore one reporting segment.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with the condensed consolidated financial statements and notes thereto appearing elsewhere in this report and our Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the United States (“U.S.”) Securities and Exchange Commission (“SEC”). This report contains forward-looking statements within the meaning of the federal securities laws. In particular, statements pertaining to our capital resources, expected use of borrowings under our credit facilities, expected use of proceeds from our ATM equity program, litigation matters, portfolio performance, leverage policy, acquisition and capital expenditure plans, capital recycling program, returns on invested capital, supply and demand for data center space, capitalization rates, rents to be received in future periods and expected rental rates on new or renewed data center space contain forward-looking statements. Likewise, all of our statements regarding anticipated market conditions, and results of operations are forward-looking statements. You can identify forward-looking statements by the use of forward-looking terminology such as “believes,” “expects,” “may,” “will,” “should,” “seeks,” “approximately,” “intends,” “plans,” “pro forma,” “estimates” or “anticipates” or the negative of these words and phrases or similar words or phrases which are predictions of or indicate future events or trends which do not relate solely to historical matters. You can also identify forward-looking statements by discussions of strategy, plans or intentions. Forward-looking statements involve numerous risks and uncertainties and you should not rely on them as predictions of future events.

Business Overview and Strategy

Digital Realty Trust, Inc., through its controlling interest in Digital Realty Trust, L.P. and its subsidiaries, delivers comprehensive space, power, and interconnection solutions that enable its customers and partners to connect with each other and service their own customers on a global technology and real estate platform. We are a leading global provider of data center, colocation and interconnection solutions for customers across a variety of industry verticals. Digital Realty Trust, Inc. operates as a REIT for federal income tax purposes, and our Operating Partnership is the entity through which we conduct our business and own our assets.

Our primary business objectives are to maximize:

| (i) | sustainable long-term growth in earnings and funds from operations per share and unit;

| (ii) | cash flow and returns to our stockholders and Digital Realty Trust, L.P.’s unitholders through the payment of distributions; and

| (iii) | return on invested capital.

​

We expect to accomplish our objectives by achieving superior risk-adjusted returns, prudently allocating capital, diversifying our product offerings, accelerating our global reach and scale, and driving revenue growth and operating efficiencies. A significant component of our current and future internal growth is anticipated through the development of our existing space held for development, acquisition of land for future development, and acquisition of new properties.

We target high-quality, strategically located properties containing the physical and connectivity infrastructure that supports the applications and operations of data center and technology industry customers and properties that may be developed for such use. Most of our data center properties contain fully redundant electrical supply systems, multiple power feeds, above-standard cooling systems, raised floor areas, extensive in-building communications cabling and high-level security systems. Fundamentally, we bring together foundational real estate and innovative technology expertise around the world to deliver a comprehensive, dedicated product suite to meet customers’ data and connectivity needs. We represent an important part of the digital economy that we believe will benefit from powerful, long-term growth drivers.

​

We have developed detailed, standardized procedures for evaluating new real estate investments to ensure that they meet our financial, technical and other criteria. We expect to continue to acquire additional assets as part of our growth strategy. We intend to aggressively manage and lease our assets to increase their cash flow. We may continue to build out our development portfolio when justified by anticipated demand and returns.

We may acquire properties subject to existing mortgage financing and other indebtedness or we may incur new indebtedness in connection with acquiring or refinancing these properties. Debt service on such indebtedness will have a priority over any cash dividends with respect to Digital Realty Trust, Inc.’s common stock and preferred stock. We are committed to maintaining a conservative capital structure. Our goal is to average through business cycles the following financial ratios: 1) a debt-to-Adjusted EBITDA ratio of 5.5x, 2) a fixed charge coverage of greater than three times, and 3) floating rate debt at less than 20% of total outstanding debt. In addition, we strive to maintain a well-laddered debt maturity schedule, and we seek to maximize the menu of our available sources of capital, while minimizing the cost.

Our current ratio of debt-to-Adjusted EBITDA is higher than we have historically experienced, which could result in adverse changes in investor perception or our credit ratings. Any such changes could negatively affect our financing activity and the market price of Digital Realty Trust, Inc.’s common stock or other securities. For additional information, please see “Risk Factors—Adverse changes in our Company’s credit ratings could negatively affect our financing activity” in our Annual Report on Form 10-K for the year ended December 31, 2022.

Revenue Base

Most of our revenue consists of rental income generated by the data centers in our portfolio. Our ability to generate and grow revenue depends on several factors, including our ability to maintain or improve occupancy rates. A summary of our data center portfolio and related square feet (in thousands) occupied (excluding space under development or held for development) is shown below. Unconsolidated portfolios shown below consist of assets owned by unconsolidated entities in which we have invested. We often provide management services for these entities under management agreements and receive management fees. These are shown as Managed Unconsolidated Portfolio. Entities for which we do not provide such services are shown as Non-Managed Unconsolidated Portfolio.

Leasing Activities

Due to the capital-intensive and long-term nature of the operations we support, our lease terms with customers are generally longer than standard commercial leases. As of March 31, 2023, our average remaining lease term was approximately five years.

Our ability to re-lease expiring space at rental rates equal to or in excess of current rental rates will impact our results of operations. The subsequent table summarizes our leasing activity in the three months ended March 31, 2023 (square feet in thousands):

(1) | For some of our properties, we calculate square footage based on factors in addition to contractually leased square feet, including power, required support space and common area.

(2) | Rental rates represent average annual estimated base cash rent per rentable square foot – calculated for each contract based on total cash base rent divided by the total number of years in the contract (including any tenant concessions). All rates were calculated in the local currency of each contract and then converted to USD based on average exchange rates for the period presented.

(3) | Excludes short-term leases.

(4) | Commencement dates for the leases signed range from 2023 to 2024.

(5) | Includes leases signed for new and re-leased space.

(6) | Other includes Powered Base Building shell capacity as well as storage and office space within fully improved data center facilities.

​

We continue to see strong demand in most of our key metropolitan areas for data center space and, subject to the supply of available data center space in these metropolitan areas, we expect average aggregate rental rates on renewed data center leases for 2023 expirations to be positive as compared with the rates currently being paid for the same space on a GAAP basis and on a cash basis. Our past performance may not be indicative of future results, and we cannot assure you that leases will be renewed or that our data centers will be re-leased at all or at rental rates equal to or above the current average rental rates. Further, re-leased/renewed rental rates in a particular metropolitan area may not be consistent with rental rates across our portfolio as a whole and may fluctuate from one period to another due to a number of factors, including local economic conditions, local supply and demand for data center space, competition from other data center developers or operators, the condition of the property and whether the property, or space within the property, has been developed.

Geographic Concentration

​

We depend on the market for data centers in specific geographic regions and significant changes in these regional or metropolitan areas can impact our future results. The following table shows the geographic concentration of annualized rent from our portfolio, including data centers held as investments in unconsolidated entities.

​ | ​ | ​ | ​
​ |  | Percentage of
​ | ​ | March 31, 2023
Metropolitan Area | ​ | Total annualized rent (1)
Northern Virginia |  | 17.9 | %

Tokyo |  | 1.8 | %
Phoenix | ​ | 1.8 | %
Other |  | 22.5 | %
Total |  | 100.0 | %

(1) | Annualized rent is monthly contractual rent (defined as cash base rent before abatements) under existing leases as of the end of the period presented, multiplied by 12. Includes consolidated portfolio and unconsolidated entities at the entities’ 100% ownership level. The aggregate amount of abatements for the three months ended March 31, 2023 was approximately $31.0 million.

Operating Expenses

Operating expenses primarily consist of utilities, property and ad valorem taxes, property management fees, insurance and site maintenance costs, and rental expenses on our ground and building leases. Our buildings require significant power to support data center operations and the cost of electric power and other utilities is a significant component of operating expenses.

Many of our leases contain provisions under which tenants reimburse us for all or a portion of property operating expenses and real estate taxes incurred by us. However, in some cases we are not entitled to reimbursement of property operating expenses, other than utility expense, and real estate taxes under our leases for Turn-Key Flex® facilities. We expect to incur additional operating expenses as we continue to expand.

Costs pertaining to our asset management function, legal, accounting, corporate governance, reporting and compliance are categorized as general and administrative costs within operating expenses.

Other key components of operating expenses include depreciation of our fixed assets, amortization of intangible assets, and transaction and integration costs.

Other Income / (Expenses)

Equity in earnings of unconsolidated entities, gain on disposition of properties, interest expense, and income tax expense make up the majority of other income/(expense). Equity in earnings of unconsolidated entities represents our share of the income/(loss) of entities in which we invest, but do not consolidate under U.S. GAAP. The largest of these investments is currently our investment in Ascenty, which is located primarily in Latin America. Our second-largest equity-method investment is Digital Core REIT, which is publicly traded on the Singapore Exchange (“SGX”) and which owns a portfolio of 11 properties operating in the United States, Canada and Germany. Refer to additional discussion of Digital Core REIT and Ascenty in the Notes to the Condensed Consolidated Financial Statements.

Results of Operations

As a result of the consistent and significant growth in our business since the first property acquisition in 2002, we evaluate period-to-period results for revenue and property level operating expenses on a stabilized versus non-stabilized portfolio basis.

Stabilized: The stabilized portfolio includes properties owned as of the beginning of all periods presented with less than 5% of total rentable square feet under development.

Non-stabilized: The non-stabilized portfolio includes: (1) properties that were undergoing, or were expected to undergo, development activities during any of the periods presented; (2) any properties contributed to joint ventures, sold, or held for sale during the periods presented; and (3) any properties that were acquired or delivered at any point during the periods presented.

A roll forward showing changes in the stabilized and non-stabilized portfolios for the three months ended March 31, 2023 as compared to December 31, 2022 is shown below.

​

​

Property level operating expenses include costs to operate and maintain the properties in our portfolio as well as taxes and insurance.

Total Utilities

Total stabilized utilities expenses increased by approximately $76.5 million in the three months ended March 31, 2023 compared to the same period in 2022 primarily due to an increase in utility consumption and higher rates at certain properties in the stabilized portfolio, largely driven by power price increases.

Total non-stabilized utilities expenses increased by approximately $28.7 million in the three months ended March 31, 2023 compared to the same period in 2022 primarily due to higher utility consumption in a growing portfolio of recently completed development sites.

The cost of electric power comprises a significant component of our operating expenses. Any additional taxation or regulation of energy use, including as a result of (i) new legislation that the U.S. Congress may pass, (ii) the regulations that the U.S. EPA has proposed or finalized, (iii) regulations under legislation that states have passed or may pass, or (iv) any further legislation or regulations in EMEA, APAC or other regions where we operate could significantly increase our costs, and we may not be able to effectively pass all of these costs on to our customers. These matters could adversely impact our business, results of operations, or financial condition.

Total Rental Property Operating and Maintenance (Excluding Utilities)

Total stabilized rental property operating and maintenance expenses (excluding utilities) increased by approximately $13.9 million in the three months ended March 31, 2023, compared to the same period in 2022 primarily due to an increase in data center labor and common area maintenance expense.

Total non-stabilized rental property operating and maintenance expenses (excluding utilities) increased $16.6 million in the three months ended March 31, 2023, compared to the same period in 2022 primarily due to higher lease and common area maintenance expense in a growing portfolio of recently completed development sites.

​

Total Property Taxes and Insurance

Total stabilized property taxes and insurance decreased by approximately $6.4 million due to timing around favorable appeals of property tax assessments impacting tax years 2021-2023, mainly within the Chicago and Silicon Valley metro areas.

Other Operating Expenses

Other operating expenses include costs which are either non-cash in nature (such as depreciation and amortization) or which do not directly pertain to operation of data center properties. A comparison of other operating expenses for the respective periods is shown below (in thousands).

Equity in Earnings (Loss) of Unconsolidated Entities

Equity in earnings (loss) of unconsolidated entities decreased approximately $46.1 million in the three months ended March 31, 2023 compared to the same period in 2022. The foreign exchange remeasurement of debt associated with our unconsolidated Ascenty entity creates volatility in our equity in earnings and drove this fluctuation.

Gain on Disposition of Properties, Net

We did not dispose of any consolidated properties in the three months ended March 31, 2023 and 2022.

Loss from Early Extinguishment of Debt

Loss from early extinguishment of debt decreased by approximately $51.1 million in the three months ended March 31, 2023 compared to the same period in 2022. The decrease is primarily due to the redemption of the 4.750% Notes due 2025 in February 2022, which resulted in a $51.1 million loss.

Interest Expense

Interest expense increased approximately $35.5 million in the three months ended March 31, 2023 compared to the same period in 2022 driven primarily by:

| (i) | an increase of $17.1 million due to the issuances of the Euro term loan (€750 million) in August 2022 along with the U.S. dollar term loan ($740 million) in January 2023;

| (ii) | an increase of $16.7 million in credit facilities interest expense as a result of higher average balances and higher interest rates;

| (iii) | an increase of $8.9 million in interest expense on unsecured debt due to the issuance of the 5.550% Notes due 2028 ($900 million) in the second half of 2022;

| (iv) | offset by an increase in capitalized interest of $12.0 million as a result of increased construction activities and higher interest rates.

​

Income Tax Expense

Income tax expense increased by approximately $8.2 million during the three months ended March 31, 2023 compared to the same period in 2022. The increase during the three-month period is due in part to the acquisition of an indirect controlling interest in Teraco in August 2022 along with other increases in various foreign jurisdictions.

Liquidity and Capital Resources

The sections “Analysis of Liquidity and Capital Resources — Parent” and “Analysis of Liquidity and Capital Resources — Operating Partnership” should be read in conjunction with one another to understand our liquidity and capital resources on a consolidated basis. The term “Parent” refers to Digital Realty Trust, Inc. on an unconsolidated basis, excluding our Operating Partnership. The term “Operating Partnership” or “OP” refers to Digital Realty Trust, L.P. on a consolidated basis.

Analysis of Liquidity and Capital Resources — Parent

Our Parent does not conduct business itself, other than acting as the sole general partner of the Operating Partnership, issuing public equity from time to time, incurring certain expenses in operating as a public company (which are fully reimbursed by the Operating Partnership) and guaranteeing certain unsecured debt of the Operating Partnership and certain of its subsidiaries and affiliates. If our Operating Partnership or such subsidiaries fail to fulfill their debt requirements, which trigger Parent guarantee obligations, then our Parent will be required to fulfill its cash payment commitments under such guarantees. Our Parent’s only material asset is its investment in our Operating Partnership.

Our Parent’s principal funding requirement is the payment of dividends on its common and preferred stock. Our Parent’s principal source of funding is the distributions it receives from our Operating Partnership.

As the sole general partner of our Operating Partnership, our Parent has the full, exclusive and complete responsibility for our Operating Partnership’s day-to-day management and control. Our Parent causes our Operating Partnership to distribute such portion of its available cash as our Parent may in its discretion determine, in the manner provided in our Operating Partnership’s partnership agreement.

As circumstances warrant, our Parent may issue equity from time to time on an opportunistic basis, dependent upon market conditions and available pricing. Any proceeds from such equity issuances would generally be contributed to our Operating Partnership in exchange for additional equity interests in our Operating Partnership. Our Operating Partnership may use the proceeds to acquire additional properties, to fund development opportunities and for general working capital purposes, including potentially for the repurchase, redemption or retirement of outstanding debt or equity securities.

Our Parent and our Operating Partnership are parties to an at-the-market (ATM) equity offering sales agreement dated April 1, 2022, as amended on March 16, 2023 (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. The sales of common stock made under the Sales Agreement will be made in “at the market” offerings as defined in Rule 415 of the Securities Act. Our Parent has used and intends to use the net proceeds from the program to temporarily repay borrowings under our Operating Partnership’s Global Revolving Credit Facilities, to acquire additional properties or businesses, to fund development opportunities and for working capital and other general corporate purposes, including potentially for the repayment of other debt or the repurchase, redemption or retirement of outstanding debt securities.

​

We believe our Operating Partnership’s sources of working capital, specifically its cash flow from operations, and funds available under its global revolving credit facility are adequate for it to make its distribution payments to our Parent and, in turn, for our Parent to make its dividend payments to its stockholders. However, we cannot assure you that our Operating Partnership’s sources of capital will continue to be available at all or in amounts sufficient to meet its needs, including making distribution payments to our Parent. The lack of availability of capital could adversely affect our Operating Partnership’s ability to pay its distributions to our Parent, which would in turn, adversely affect our Parent’s ability to pay cash dividends to its stockholders.

Future Uses of Cash — Parent

Our Parent may from time to time seek to retire, redeem or repurchase its equity or the debt securities of our Operating Partnership or its subsidiaries through cash purchases and/or exchanges for equity securities in open market purchases, privately negotiated transactions or otherwise. Such repurchases, redemptions or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions or other factors. The amounts involved may be material.

​

Dividends and Distributions — Parent

Our Parent is required to distribute 90% of its taxable income (excluding capital gains) on an annual basis to continue to qualify as a REIT for U.S. federal income tax purposes. Our Parent intends to make, but is not contractually bound to make, regular quarterly distributions to its common stockholders from cash flow from our Operating Partnership’s operating activities. While historically our Parent has satisfied this distribution requirement by making cash distributions to its stockholders, it may choose to satisfy this requirement by making distributions of cash or other property. All such distributions are at the discretion of our Parent’s Board of Directors. Our Parent considers market factors and our Operating Partnership’s performance in addition to REIT requirements in determining distribution levels. Our Parent has distributed at least 100% of its taxable income annually since inception to minimize corporate level federal and state income taxes. Amounts accumulated for distribution to stockholders are invested primarily in interest-bearing accounts and short-term interest-bearing securities, in a manner consistent with our intention to maintain our Parent’s status as a REIT.

As a result of this distribution requirement, our Operating Partnership cannot rely on retained earnings to fund its ongoing operations to the same extent that other companies whose parent companies are not REITs can. Our Parent may need to continue to raise capital in the debt and equity markets to fund our Operating Partnership’s working capital needs, as well as potential developments at new or existing properties, acquisitions or investments in existing or newly created joint ventures. In addition, our Parent may be required to use borrowings under the Operating Partnership’s global revolving credit facility (which is guaranteed by our Parent), if necessary, to meet REIT distribution requirements and maintain our Parent’s REIT status.

Distributions out of our Parent’s current or accumulated earnings and profits are generally classified as ordinary income whereas distributions in excess of our Parent’s current and accumulated earnings and profits, to the extent of a stockholder’s U.S. federal income tax basis in our Parent’s stock, are generally classified as a return of capital. Distributions in excess of a stockholder’s U.S. federal income tax basis in our Parent’s stock are generally characterized as capital gain. Cash provided by operating activities has been generally sufficient to fund distributions on an annual basis. However, we may also need to utilize borrowings under the global revolving credit facility to fund distributions.

For additional information regarding dividends declared and paid by our Parent on its common and preferred stock for the three months ended March 31, 2023, see Note 11. “Equity and Capital” to our condensed consolidated financial statements contained herein.

​

Analysis of Liquidity and Capital Resources — Operating Partnership

As of March 31, 2023, we had $131.4 million of cash and cash equivalents, excluding $10.2 million of restricted cash. Restricted cash primarily consists of contractual capital expenditures plus other deposits. As circumstances warrant, our Operating Partnership may dispose of stabilized assets or enter into joint venture arrangements with institutional investors or strategic partners, on an opportunistic basis dependent upon market conditions. Our Operating Partnership may use the proceeds from such dispositions to acquire additional properties, to fund development opportunities and for general working capital purposes, including the repayment of indebtedness. Our liquidity requirements primarily consist of:

| ● | operating expenses;

| ● | development costs and other expenditures associated with our properties;

| ● | distributions to our Parent to enable it to make dividend payments;

| ● | distributions to unitholders of common limited partnership interests in Digital Realty Trust, L.P.;

| ● | debt service; and

| ● | potentially, acquisitions.

​

Future Uses of Cash

Our properties require periodic investments of capital for customer-related capital expenditures and for general capital improvements. Depending upon customer demand, we expect to incur significant improvement costs to build out and develop additional capacity. At March 31, 2023, we had open commitments, related to construction contracts of approximately $2.6 billion, including amounts reimbursable of approximately $30.6 million.

We currently expect to incur approximately $1.7 billion to $1.9 billion of capital expenditures for our development programs during the nine months ending December 31, 2023. This amount could go up or down, potentially materially, based on numerous factors, including changes in demand, leasing results and availability of debt or equity capital.

Land inventory and space held for development reflect cumulative cost spent pending future development. Base building construction consists of ongoing improvements to building infrastructure in preparation for future data center fit-out. Data center construction includes 8.8 million square feet of Turn Key Flex® and Powered Base Building® product. We expect to deliver the space within 12 months; however, lease commencement dates may significantly impact final delivery schedules. Equipment pool and other inventory represent the value of long-lead equipment and materials required for timely deployment and delivery of data center construction fit-out. Campus, tenant improvements and other costs include the value of development work which benefits space recently converted to our operating portfolio and is composed primarily of shared infrastructure projects and first-generation tenant improvements.

Capital Expenditures (Cash Basis)

​

Our development capital expenditures are generally funded by our available cash and equity and debt capital.

48

Table of Contents

​

Indirect costs, including interest, capitalized in the three months ended March 31, 2023 and 2022 were $50.5 million and $35.6 million, respectively. Capitalized interest comprised approximately $26.8 million and $14.8 million of the total indirect costs capitalized for the three months ended March 31, 2023 and 2022, respectively. Capitalized interest in the three months ended March 31, 2023 increased, compared to the same period in 2022, due to an increase in qualifying activities.

Excluding capitalized interest, indirect costs in the three months ended March 31, 2023 increased compared to the same period in 2022 due primarily to capitalized amounts relating to compensation expense of employees directly engaged in construction activities. See “Future Uses of Cash” for a discussion of the amount of capital expenditures we expect to incur during the year ending December 31, 2023.

Consistent with our growth strategy, we actively pursue potential acquisition opportunities, with due diligence and negotiations often at different stages at different times. The dollar value of acquisitions for the year ending December 31, 2023 will depend upon numerous factors, including customer demand, leasing results, availability of debt or equity capital and acquisition opportunities. Further, the growing acceptance by private institutional investors of the data center asset class has generally pushed capitalization rates lower, as such private investors may often have lower return expectations than us. As a result, we anticipate near-term single asset acquisitions activity to comprise a smaller percentage of our growth while this market dynamic persists.

We may from time to time seek to retire or repurchase our outstanding debt or the equity of our Parent through cash purchases and/or exchanges for equity securities of our Parent in open market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend upon prevailing market conditions, our liquidity requirements, contractual restrictions or other factors. The amounts involved may be material.

Sources of Cash

We expect to meet our short-term and long-term liquidity requirements, including payment of scheduled debt maturities and funding of acquisitions and non-recurring capital improvements, with net cash from operations, future long-term secured and unsecured indebtedness and the issuance of equity and debt securities and the proceeds of equity issuances by our Parent. We also may fund future short-term and long-term liquidity requirements, including acquisitions and non-recurring capital improvements, using our Global Revolving Credit Facilities pending permanent financing. As of May 1, 2023, we had approximately $1.1 billion of borrowings available under our Global Revolving Credit Facilities.

Our Global Revolving Credit Facilities provide for borrowings up to $3.9 billion (including approximately $0.2 billion available to be drawn on the Yen revolving credit facility). We have the ability from time to time to increase the size of the global revolving credit facility by up to $750 million, subject to the receipt of lender commitments and other conditions precedent. Both facilities mature on January 24, 2026, with two six-month extension options available. These facilities also feature a sustainability-linked pricing component, with pricing subject to adjustment based on annual performance targets, further demonstrating our continued leadership and commitment to sustainable business practices. We have used and intend to use available borrowings under the Global Revolving Credit Facilities to fund our liquidity requirements from time to time. For additional information regarding our global revolving credit facility, see Note 9. “Debt of the Operating Partnership” to our condensed consolidated financial statements contained herein.

On October 25, 2022, the Company, the Operating Partnership, and certain of the Operating Partnership’s subsidiaries entered into an escrow agreement, pursuant to which the Operating Partnership delivered executed signature pages to a new term loan agreement to be held in escrow upon satisfaction of specific terms. On January 9, 2023, the terms and conditions of the agreement were satisfied, and, on such date, the term loan was deemed executed and became effective. The Term Loan Facility provides for a $740 million senior unsecured term loan facility and borrowings in U.S. dollars. The Term Loan Facility will mature on March 31, 2025, subject to one twelve-month extension at the Operating Partnership’s option; provided, that the Operating Partnership must pay a 0.1875% extension fee based on the then-outstanding principal amount of the term loans under the Term Loan Facility.

In December 2022, Teraco entered into a syndicated loan facility worth R11.8 billion (approximately $681 million based on the exchange rate on December 6, 2022), of which R5.7 billion (approximately $329 million based on the exchange rate on December 6, 2022) will be used to finance the company’s continued growth and R6.1 billion (approximately $329 million based on the exchange rate on December 6, 2022) will refinance and extend the average maturity profile of existing drawn debt. The new facilities mature in December 2028.

Distributions

All distributions on our units are at the discretion of our Parent’s Board of Directors. For additional information regarding distributions paid on our common and preferred units for the three months ended March 31, 2023, see Note 11. “Equity and Capital” to our condensed consolidated financial statements contained herein.

Outstanding Consolidated Indebtedness

Fixed rate (including hedged variable rate debt) | ​ |  | 2.76 | %
Variable rate | ​ |  | 4.30 | %
Effective interest rate | ​ |  | 2.51 | %

​

Our ratio of debt to total enterprise value was approximately 37% (based on the closing price of Digital Realty Trust, Inc.’s common stock on March 31, 2023 of $98.31). For this purpose, our total enterprise value is defined as the sum of the market value of Digital Realty Trust, Inc.’s outstanding common stock (which may decrease, thereby increasing our debt to total enterprise value ratio), plus the liquidation value of Digital Realty Trust, Inc.’s preferred stock, plus the aggregate value of Digital Realty Trust, L.P. units not held by Digital Realty Trust, Inc. (with the per unit value equal to the market value of one share of Digital Realty Trust, Inc.’s common stock and excluding long-term incentive units, Class C units and Class D units), plus the book value of our total consolidated indebtedness.

The variable rate debt shown above bears interest based on various one-month SOFR, EURIBOR, SORA, BBR, HIBOR, TIBOR, Base CD Rate and CDOR rates, depending on the respective agreement governing the debt, including our Global Revolving Credit Facilities and unsecured term loans. As of March 31, 2023 our debt had a weighted average term to initial maturity of approximately 4.8 years (or approximately 5.0 years assuming exercise of extension options).

As of March 31, 2023, our pro-rata share of secured debt of unconsolidated entities was approximately $1,123.4 million.

Cash Flows

​

The following summary discussion of our cash flows is based on the condensed consolidated statements of cash flows and is not meant to be an all-inclusive discussion of the changes in our cash flows for the periods presented below.

​

Comparison of Three Months Ended March 31, 2023 to Three Months Ended March 31, 2022

The following table shows cash flows and ending cash, cash equivalents and restricted cash balances for the respective periods (in thousands).

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | Three Months Ended March 31,
​ | 2023 |  | 2022 |  | Change
Net cash provided by operating activities | $ | 349,726 | ​ | $ | 277,685 | ​ | $ | 72,041

Net (decrease) increase in cash, cash equivalents and restricted cash | $ | (8,373) | ​ | $ | 36,889 | ​ | $ | (45,262)

​

The changes in the activities that comprise the increase in net cash used in investing activities for the three months ended March 31, 2023 as compared to the three months ended March 31, 2022 consisted of the following amounts (in thousands).

​ | ​ | ​
​ | Change
​ | 2023 vs 2022
Increase in cash used for business combination / assets acquired | $ | (36,868)
Increase in cash used for improvements to investments in real estate | ​ | (219,943)
Decrease in cash contributed to investments in unconsolidated entities | ​ | 203,187
Other changes |  | 23,709
Increase in net cash used in investing activities | $ | (29,915)

​

The increase in net cash used in investing activities was primarily due to:

| (i) | an increase in spend on development projects of approximately $214.0 million;

| (ii) | offset by investments in various unconsolidated entities in March 31, 2022, primarily with Mitsubishi and Ascenty.

​

The changes in the activities that comprise the increase in net cash used in financing activities for the three months ended March 31, 2023 as compared to the three months ended March 31, 2022 consisted of the following amounts (in thousands).

​ | ​ | ​
​ | Change
​ | 2023 vs 2022
Decrease in cash provided by short-term borrowings | $ | (205,872)
Decrease in cash provided by proceeds from secured / unsecured debt | ​ | (334,356)

Increase in cash used for dividend and distribution payments |  | (33,065)
Other changes, net | ​ | 38,986
Decrease in net cash provided by financing activities | $ | (87,388)

​

The decrease in net cash provided by financing activities was primarily due to:

| (i) | a decrease in cash proceeds from short-term borrowings;

| (ii) | a decrease in cash provided by proceeds from secured / unsecured debt due to the issuance of notes in 2022 (2032 Notes in January 2022 and Swiss Franc Notes in March 2022), offset by the closing of the USD Term Loan in January 2023;

| (iii) | a decrease in cash used for repayment of unsecured notes (in 2022, we redeemed the 4.750% Notes due 2025 ($450 million); and

| (iv) | an increase in dividend and distribution payments due to an increased number of common shares and common units outstanding.

Noncontrolling Interests in Operating Partnership

Noncontrolling interests relate to the common units in Digital Realty Trust, L.P. that are not owned by Digital Realty Trust, Inc., which, as of March 31, 2023, amounted to 2.2%% of Digital Realty Trust, L.P. common units. Historically, Digital Realty Trust, L.P. has issued common units to third party sellers in connection with our acquisition of real estate interests from such third parties.

Limited partners have the right to require Digital Realty Trust, L.P. to redeem part or all of their common units for cash based upon the fair market value of an equivalent number of shares of Digital Realty Trust, Inc. common stock at the time of the redemption. Alternatively, we may elect to acquire those common units in exchange for shares of Digital Realty Trust, Inc. common stock on a one-for-one basis, subject to adjustment in the event of stock splits, stock dividends, issuance of stock rights, specified extraordinary distributions and similar events. As of March 31, 2023, approximately 0.2 million common units of Digital Realty Trust, L.P. that were issued to certain former unitholders of DuPont Fabros Technology, L.P. in connection with the Company’s acquisition of DuPont Fabros Technology, Inc. were outstanding, which are subject to certain restrictions and, accordingly, are not presented as permanent capital in the condensed consolidated balance sheet.

Inflation

Many of our leases provide for separate real estate tax and operating expense escalations. In addition, many of the leases provide for fixed base rent increases. We believe that inflationary increases may be at least partially offset by the contractual rent increases and expense escalations described above. A period of inflation, however, could cause an increase in the cost of our variable-rate borrowings, including borrowings under our Global Revolving Credit Facilities, borrowings under our unsecured term loans and issuances of unsecured senior notes.

Funds from Operations

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) (computed in accordance with GAAP), excluding gains (or losses) from sales of property, a gain from a pre-existing relationship, impairment charges and real estate related depreciation and amortization (excluding amortization of deferred financing costs) 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 properties 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 properties, 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.

(2) | Rollover Shareholders have the right to put their shares in Remaining Teraco Interests to the Company in exchange for cash or the equivalent value of shares of the Company common stock, or a combination thereof. U.S. GAAP requires the Company to assume the put right is settled in shares for purposes of calculating diluted EPS. This same approach was utilized to calculate FFO/share. When calculating diluted FFO, the net income allocated to the Rollover Shareholders is added back to the FFO numerator as the denominator assumes all shares have been put back to the Company.

(3) | For all periods presented, we have excluded the effect of the 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, as they would be anti-dilutive.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our future income, cash flows and fair values relevant to financial instruments depend upon prevalent market interest rates. Market risk refers to the risk of loss from adverse changes in market prices and interest rates. We do not use derivatives for trading or speculative purposes and only enter into contracts with major financial institutions based on their credit ratings and other factors.

Analysis of Debt between Fixed and Variable Rate

We use interest rate swap agreements and fixed rate debt to reduce our exposure to interest rate movements. As of March 31, 2023, our consolidated debt was as follows (in millions):

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | ​ | ​ |  | Estimated Fair
​ | ​ | Carrying Value |  | Value
Fixed rate debt | ​ | $ | 11,950.1 | ​ | $ | 10,105.1
Variable rate debt subject to interest rate swaps | ​ |  | 2,654.1 | ​ |  | 2,654.1
Total fixed rate debt (including interest rate swaps) | ​ |  | 14,604.2 | ​ |  | 12,759.2
Variable rate debt | ​ |  | 3,400.9 | ​ |  | 3,400.9
Total outstanding debt | ​ | $ | 18,005.1 | ​ | $ | 16,160.1

​

Sensitivity to Changes in Interest Rates

The following table shows the effect if assumed changes in interest rates occurred, based on fair values and interest expense as of March 31, 2023:

​ | ​ | ​ | ​
​ |  | Change
Assumed event | ​ | ($ millions)
Increase in fair value of interest rate swaps following an assumed 10% increase in interest rates | ​ | $ | (0.2)
Decrease in fair value of interest rate swaps following an assumed 10% decrease in interest rates | ​ |  | 0.2
Increase in annual interest expense on our debt that is variable rate and not subject to swapped interest following a 10% increase in interest rates | ​ |  | 17.0
Decrease in annual interest expense on our debt that is variable rate and not subject to swapped interest following a 10% decrease in interest rates | ​ |  | (17.0)
Increase in fair value of fixed rate debt following a 10% decrease in interest rates | ​ |  | 278.5
Decrease in fair value of fixed rate debt following a 10% increase in interest rates | ​ |  | (265.4)

​

Interest risk amounts were determined by considering the impact of hypothetical interest rates on our financial instruments. These analyses do not consider the effect of any change in overall economic activity that could occur in that environment. Further, in the event of a change of that magnitude, we may take actions to further mitigate our exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, these analyses assume no changes in our financial structure.

Foreign Currency Exchange Risk

We are subject to risk from the effects of exchange rate movements of a variety of foreign currencies, which may affect future costs and cash flows. Our primary currency exposures are to the Euro, Japanese yen, British pound sterling, Singapore dollar and South African rand. Our exposure to foreign exchange risk related to the Brazilian real is limited to the impact that currency has on our share of the Ascenty entity’s operations and financial position. We attempt to mitigate a portion of the risk of currency fluctuations by financing our investments in local currency denominations in order to reduce our exposure to any foreign currency transaction gains or losses resulting from transactions entered into in currencies other than the functional currencies of the associated entities. In addition, we may also hedge well-defined transactional exposures with foreign currency forwards or options, although there can be no assurances that these will be effective. As a result, changes in the relation of any such foreign currency to U.S. dollar may affect our revenues, operating margins and distributions and may also affect the book value of our assets and the amount of stockholders’ equity.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures (Digital Realty Trust, Inc.)

The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in its reports filed under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to its management, including its chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, the Company’s management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and its management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Also, the Company has investments in certain unconsolidated entities, which are accounted for using the equity method of accounting. As the Company does not control or manage these entities, its disclosure controls and procedures with respect to such entities may be substantially more limited than those it maintains with respect to its consolidated subsidiaries.

As required by Rule 13a-15(b) or Rule 15d-15(b) of the Securities Exchange Act of 1934, as amended, management of the Company carried out an evaluation, under the supervision and with participation of its chief executive officer and chief financial officer, of the effectiveness of the design and operation of its disclosure controls and procedures that were in effect as of the end of the quarter covered by this report. Based on the foregoing, the Company’s chief executive officer and chief financial officer concluded that its disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

​

There have been no changes in the Company’s internal control over financial reporting during its most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, its internal control over financial reporting.
