EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the quarter ended March 31, 2022 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. Unless 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. In statements regarding qualification as a REIT, such terms refer solely to Digital Realty Trust, Inc. As of March 31, 2022, 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, 2022, 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 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, 2021 (“2021 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 that we 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. 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, most 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, 2022, certain of our data centers, primarily in Europe and Singapore, are subject to ground leases. As of March 31, 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 amounted to approximately $37.4 million and $35.6 million for the three months ended March 31, 2022 and 2021, respectively.

Digital Core REIT owns 10 operating data center properties. Digital Core REIT and its 10 operating properties are collectively referred to as the “DCREIT”. The Company’s ownership interest in DCREIT consists of units of DCRU, as well as an ownership interest in the operating properties of DCRU. As of March 31, 2022, the Company held 35% of the outstanding DCRU units and separately owned a 10% retained interest in the underlying operating properties.

​

on the closing price per unit of $1.11 as of March 31, 2022, the fair value of the units the Company owns in DCRU was $433 million. This value does 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 ownership interest in DCREIT as an equity method investment (and not at fair value) based on the significant influence it is able to exert on DCREIT.

​

Pursuant to contractual agreements with the DCREIT, the Company will earn fees for asset and property management services as well as fees for aiding the DCREIT in future acquisition, disposition and development activities. Certain of these fees are payable to the Company in the form of additional units in the DCREIT or in cash. During the three months ended March 31, 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 $22.2 million and $20.9 million as of March 31, 2022 and December 31, 2021, 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.

​

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.

10. Equity and Capital

Equity Distribution Agreement

Digital Realty Trust, Inc. and Digital Realty Trust, L.P., were parties to an at-the-market (ATM) equity offering sales agreement dated January 4, 2019, as amended in 2020 (the “Sales Agreement”). Pursuant to the Sales Agreement, Digital Realty Trust, Inc. was able to issue and sell common stock having an aggregate offering price of up to $1.0 billion through various named agents from time to time. For the three months ended March 31, 2022 and 2021, there was no activity under the Sales Agreement.

Subsequent to quarter-end, Digital Realty Trust, Inc. and Digital Realty Trust, L.P., entered into an ATM equity offering sales agreement dated April 1, 2022 (the “2022 Sales Agreement”). Upon entry into the 2022 Sales Agreement, we terminated our prior ATM program. At the time of the termination, $577.6 million remained unsold under the prior program. Pursuant to the 2022 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.

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.

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 March 31, 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 March 31, 2022 and December 31, 2021 (in thousands):

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 $716.7 million and $1,074.7 million based on the closing market price of Digital Realty Trust, Inc. common stock on March 31, 2022 and December 31, 2021, respectively.

The following table shows activity for the noncontrolling interests in the Operating Partnership for the three months ended March 31, 2022 (in thousands):

12. 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 Awards in the form of Class D units of the Operating Partnership and Restricted Stock Units covering shares of Digital Realty Trust, Inc.’s common stock may be issued to officers and employees of the Company. Depending on the 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”).

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 three months ended March 31, 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 then 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 the Company’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 the attainment of performance metrics related to the successful integration of the Interxion business and continued service.

As of March 31, 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.

13. Derivative Instruments

We had no material outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk as of March 31, 2022.

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, 2022, we had no material interest rate swap agreements outstanding.

Upon entering into derivatives, we would have agreements with each of our derivative counterparties that contain a provision where we could be declared in default on our derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to our default on the indebtedness. As of March 31, 2022, we did not have any material derivatives outstanding.

​

14. 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 March 31, 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 March 31, 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.

​

15. 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, 2022, we had open commitments, including amounts reimbursable by customers of approximately $49.1 million, related to construction contracts of approximately $1.4 billion.

In the ordinary course of our business, we may become subject to various legal proceedings. As of March 31, 2022, we were not a party to any legal proceedings which we believe would have a material adverse effect on our operations or financial position.

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, 2021, 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, expected settlement and use of proceeds from our forward sale agreements, 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, as well as our discussion of “Factors Which May Influence Future Results of Operations,” contain forward-looking statements. Likewise, all of our statements regarding anticipated market conditions, demographics 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 and discussions 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. Forward-looking statements depend on assumptions, data or methods that may be incorrect or imprecise and that we may not be able to realize. We do not guarantee that the transactions and events described will happen as described or that they will happen at all. The following factors, among others, could cause actual results and future events to differ materially from those set forth or contemplated in the forward-looking statements: reduced demand for data centers or decreases in information technology spending; increased competition or available supply of data center space; decreased rental rates, increased operating costs or increased vacancy rates; the impact on our, our customers’ and our suppliers’ operations during a pandemic, such as COVID-19; changes in political conditions, geopolitical turmoil, political instability, civil disturbances, restrictive governmental actions or nationalization in the countries in which we operate; the suitability of our data centers and data center infrastructure, delays or disruptions in connectivity or availability of power, or failures or breaches of our physical and information security infrastructure or services; our dependence upon significant customers, bankruptcy or insolvency of a major customer or a significant number of smaller customers, or defaults on or non-renewal of leases by customers; breaches of our obligations or restrictions under our contracts with our customers; our inability to successfully develop and lease new properties and development space, and delays or unexpected costs in development of properties; the impact of current global and local economic, credit and market conditions; global supply chain or procurement disruptions, or increased supply chain costs; our inability to retain data center space that we lease or sublease from third parties; information security and data privacy breaches; difficulties managing an international business and acquiring or operating properties in foreign jurisdictions and unfamiliar metropolitan areas; our failure to realize the intended benefits from, or disruptions to our plans and operations or unknown or contingent liabilities related to, our recent and future acquisitions; our inability to achieve expected revenue synergies or cost savings as a result of our combination with Interxion; our failure to successfully integrate and operate acquired or developed properties or businesses; difficulties in identifying properties to acquire and completing acquisitions; risks related to joint venture investments, including as a result of our lack of control of such investments; risks associated with using debt to fund our business activities, including re-financing and interest rate risks, our failure to repay debt when due, adverse changes in our credit ratings or our breach of covenants or other terms contained in our loan facilities and agreements; our failure to obtain necessary debt and equity financing, and our dependence on external sources of capital; financial market fluctuations and changes in foreign currency exchange rates; adverse economic or real estate developments in our industry or the industry sectors that we sell to, including risks relating to decreasing real estate valuations and impairment charges and goodwill and other intangible asset impairment charges; our inability to manage our growth effectively; losses in excess of our insurance coverage; our inability to attract and retain talent; environmental liabilities, risks related to natural disasters and our inability to achieve our sustainability goals; our inability to comply with rules and regulations applicable to our Company; Digital Realty Trust, Inc.’s failure to maintain its status as a REIT for federal income tax purposes; Digital Realty Trust, L.P.’s failure to qualify as a partnership for federal income tax purposes; restrictions on our ability to engage in certain business

​

activities; and changes in local, state, federal and international laws and regulations, including related to taxation, real estate and zoning laws, and increases in real property tax rates.

While forward-looking statements reflect our good faith beliefs, they are not guarantees of future performance. We disclaim any obligation to publicly update or revise any forward-looking statement to reflect changes in underlying assumptions or factors, new information, data or methods, future events or other changes.

The risks included here are not exhaustive, and additional factors could adversely affect our business and financial performance, including factors and risks included in our annual report on Form 10-K for the year ended December 31, 2021. Moreover, we operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time and it is not possible for management to identify all such risk factors, nor can we assess the impact of all such risk factors on the business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Given these risks and uncertainties, you should not place undue reliance on forward-looking statements as a prediction of actual results.

Occupancy percentages included in the following discussion, for some of our properties, are calculated based on factors in addition to contractually leased square feet, including available power, required support space and common area.

As used in this report: “Ascenty entity” refers to the entity, which owns and operates Ascenty, formed with Brookfield Infrastructure.

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

35

​

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. We target a debt-to-Adjusted EBITDA ratio at or less than 5.5x, fixed charge coverage of greater than three times, and 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.

Summary of 2022 Significant Activities

We completed the following significant activities during the first quarter of 2022 as described in the Notes to the Condensed Consolidated Financial Statements:

| ● | In January, we issued and sold €750.0 million aggregate principal amount of 1.375% Guaranteed Notes due 2032 (the “2032 Notes”). The 2032 Notes are senior unsecured obligations of Digital Intrepid Holding B.V. and are fully and unconditionally guaranteed by Digital Realty Trust, Inc. and Digital Realty Trust, L.P. Net proceeds from the offering were approximately €737.5 million (approximately $835.3 million based on the exchange rate on January 18, 2022) after deducting managers’ discounts and estimated offering expenses.

| ● | In February, we redeemed $450.0 million of 4.750% Notes due 2025. As part of this redemption, we recorded a $51.1 million loss on extinguishment of debt.

| ● | In March, we issued and sold CHF 100 million aggregate principal amount of 0.600% Guaranteed Notes due 2023 (the “2023 Notes”) and CHF 150 million aggregate principal amount of 1.700% Guaranteed Notes due 2027 (the “2027 Notes” and, together with the 2023 Notes, the “Swiss Franc Notes”). The Swiss Franc Notes are senior unsecured obligations of Digital Intrepid Holding B.V. and are fully and unconditionally guaranteed by Digital Realty Trust, Inc. and Digital Realty Trust, L.P. Net proceeds from the offering of the Swiss Franc Notes were approximately CHF 248.6 million (approximately $269.2 million based on the exchange rate on March 30, 2022) after deducting the managers’ commissions and certain offering expenses.

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 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, 2022, 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, 2022:

(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 2022 to 2023.

(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 2022 expirations to be slightly 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

37

​

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, 2022

Atlanta |  | 1.5 | %
Tokyo | ​ | 1.5 | %
Other |  | 20.4 | %
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, 2022 was approximately $30.0 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.

38

​

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, 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 Brazil. 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 10 properties operating in the United States and Canada. 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 vs. 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.

Comparison of the Three Months Ended March 31, 2022 to the Three Months Ended March 31, 2021

Revenues

Total operating revenues as shown on our condensed consolidated income statements was as follows (in thousands):

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Three Months Ended March 31, | ​
​ |  | 2022 |  | 2021 |  | $ Change | ​ | % Change | ​

Rental and other services | ​ | ​ | 1,121,550 | ​ | ​ | 1,087,906 | ​ | ​ | 33,644 | ​ | 3.1 | % | ​
Fee income and other | ​ | ​ | 5,772 | ​ | ​ | 2,485 | ​ | ​ | 3,287 | ​ | 132.3 | % | ​
Total operating revenues | ​ | $ | 1,127,322 | ​ | $ | 1,090,391 | ​ | $ | 36,931 | ​ | 3.4 | % | ​

​

Total operating revenues increased by approximately $36.9 million in the three months ended March 31, 2022, compared to the same period in 2021, driven primarily by growth in non-stabilized rental and other services revenue.

Stabilized rental and other services revenue decreased $23.3 million in the three months ended March 31, 2022, compared to the same period in 2021, primarily due to (i) $14.8 million increase in bad debt and straight-line rent reserves, and (ii) lower occupancy, all of which was partially offset by (iii) a net increase in tenant reimbursements related to higher utility consumption for the three months ended March 31, 2022.

Non-stabilized rental and other services revenue increased $56.9 million in the three months ended March 31, 2022, compared to the same period in 2021, driven primarily by the completion of our global development pipeline and related lease up operating activities and expansion into new markets in EMEA offset by the impact of properties sold in 2021. An increase of $32.3 million in revenue was generated from an APAC property, which was not operational for the three months ended March 31, 2021.

Total Property Level Expenses | ​ | $ | 485,817 | ​ | $ | 414,282 | ​ | $ | 71,535 | ​ | 17.3 | %

​

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

Stabilized property operating and maintenance expenses increased by approximately $4.8 million in the three months ended March 31, 2022, compared to the same period in 2021, primarily due to higher utility consumption at certain properties in the stabilized portfolio.

Non-stabilized property operating and maintenance expenses increased $69.1 million in the three months ended March 31, 2022, compared to the same period in 2021, primarily due to higher utility consumption.

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 the EU, 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.

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 three months ended March 31, 2022 and 2021 is shown below.

​

Equity in earnings (loss) of unconsolidated entities

Equity in earnings (loss) of unconsolidated entities increased approximately $84.0 million in the three months ended March 31, 2022, compared to the same period in 2021, primarily due to foreign exchange remeasurement of debt associated with our Ascenty unconsolidated entity.

Gain on Disposition of Properties, Net

Gain on disposition of properties, net decreased approximately $331.2 million in the three months ended March 31, 2022, compared to the same period in 2021. In March 2021, we sold a portfolio of 11 data centers in Europe (four in the United Kingdom, three in the Netherlands, three in France and one in Switzerland) to Ascendas Reit, a CapitaLand sponsored REIT, for total purchase consideration of approximately $680.0 million resulting in a gain of approximately $333.3 million. We did not dispose of any properties in the three months ended March 31, 2022.

Loss from Early Extinguishment of Debt

Loss from early extinguishment of debt increased approximately $32.8 million in the three months ended March 31, 2022, compared to the same period in 2021. The increase is primarily due to the redemption of the 4.750% Notes due 2025 in February 2022, which resulted in a $51.1 million loss, offset by the redemption 2.750% Notes due 2023 in February 2021, which resulted in a $18.3 million loss.

Income Tax Expense

Income tax expense increased by $5.7 million during the three months ended March 31, 2022, compared to the same period in 2021. The increase was driven primarily by an increase of $2.9 million in deferred taxes and a $2.8 million increase in current taxes.

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

41

​

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 were parties to an at-the-market (ATM) equity offering sales agreement dated January 4, 2019, as amended in 2020 (the “Sales Agreement”). In accordance with the Sales Agreement, following the date of the 2020 amendment, Digital Realty Trust, Inc. could offer and sell shares of its common stock having an aggregate offering price of up to $1.0 billion. Subsequent to quarter-end, Digital Realty Trust, Inc. and Digital Realty Trust, L.P., entered into an ATM equity offering sales agreement dated April 1, 2022 (the “2022 Sales Agreement”). Upon entry into the 2022 Sales Agreement, we terminated our prior ATM program. At the time of the termination, $577.6 million remained unsold under the prior program. Pursuant to the 2022 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 2022 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.

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. 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. The forward purchasers had also granted to the underwriters an option, exercisable until October 13, 2021, to purchase up to 937,500 additional shares at a price of $155.69, which represents the initial price to the public less the underwriting discount. The underwriters opted not to exercise their option within the specified time period.

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 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

42

​

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, which are 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, 2022, see Note 10. “Equity and Capital” to our condensed consolidated financial statements contained herein.

Analysis of Liquidity and Capital Resources — Operating Partnership

As of March 31, 2022, we had $158.0 million of cash and cash equivalents, excluding $10.4 million of restricted cash. Restricted cash primarily consists of contractual capital expenditures plus other deposits. 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, 2022, we had open commitments, related to construction contracts of approximately $1.4 billion, including amounts reimbursable of approximately $49.1 million.

We currently expect to incur approximately $1.9 billion to $2.1 billion of capital expenditures for our development programs during the nine months ending December 31, 2022. 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.

​

We are party to a definitive agreement under which we committed to acquire approximately 55% of the total equity interest in Teraco, Africa’s leading carrier-neutral colocation provider. The transaction values Teraco at approximately $3.5 billion. The transaction is dependent upon customary closing conditions.

Development Projects

The costs we incur to develop our properties is a key component of our liquidity requirements. The following table summarizes our cumulative investments in current development projects as well as expected future investments in these projects as of the periods presented, excluding costs incurred or to be incurred by unconsolidated entities.

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 7.3 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)

The table below summarizes our capital expenditure activity for the three months ended March 31, 2022 and 2021 (in thousands):

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Three Months Ended March 31,
​ |  | 2022 |  | 2021
Development projects | ​ | $ | 430,947 | ​ | $ | 439,793
Enhancement and improvements | ​ |  | 5,387 | ​ |  | 58
Recurring capital expenditures | ​ |  | 46,770 | ​ |  | 39,522
Total capital expenditures (excluding indirect costs) | ​ | $ | 483,104 | ​ | $ | 479,373

​

44

​

For the three months ended March 31, 2022, total capital expenditures increased $3.7 million to approximately $483.1 million from $479.4 million for the same period in 2021. Capital expenditures on our development projects plus our enhancement and improvements projects for the three months ended March 31, 2022 were approximately $436.3 million. Our development capital expenditures are generally funded by our available cash and equity and debt capital.

Indirect costs, including capitalized interest, capitalized in the three months ended March 31, 2022 and 2021 were $35.6 million and $29.2 million, respectively. Capitalized interest comprised approximately $14.8 million and $11.4 million of the total indirect costs capitalized for the three months ended March 31, 2022 and 2021, respectively. Capitalized interest in the three months ended March 31, 2022 increased, compared to the same period in 2021, due to an increase in qualifying activities.

Excluding capitalized interest, indirect costs in the three months ended March 31, 2022 increased compared to the same period in 2021 due primarily to capitalized amounts relating to compensation expense of employees directly engaged in construction activities. See “—Future Uses of Cash” below for a discussion of the amount of capital expenditures we expect to incur during the year ending December 31, 2022.

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, 2022 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 3, 2022, we had approximately $2.8 billion of borrowings available under our global revolving credit facilities.

Our global revolving credit facility provides for borrowings up to $3.75 billion. 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. The global revolving credit facility matures on January 24, 2026, with two six-month extension options available. We have used and intend to use available borrowings under the global revolving credit facility to fund our liquidity requirements from time to time.

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, 2022, see Note 10. “Equity and Capital” to our condensed consolidated financial statements contained herein.

​

Outstanding Consolidated Indebtedness

​

The table below summarizes our outstanding debt as of March 31, 2022 (in millions):

​

​ | ​ | ​ | ​ | ​
Debt Summary: |  | ​ |  | ​
Fixed rate | ​ | $ | 13,199.6 | ​
Variable rate debt subject to interest rate swaps | ​ |  | 2.3 | ​
Total fixed rate debt (including interest rate swaps) | ​ |  | 13,201.9 | ​
Variable rate—unhedged | ​ |  | 1,307.1 | ​
Total | ​ | $ | 14,509.0 | ​
Percent of Total Debt: | ​ |  |  | ​
Fixed rate (including swapped debt) | ​ |  | 91.0 | %
Variable rate | ​ |  | 9.0 | %
Total | ​ |  | 100.0 | %
​ | ​ | ​ | ​ | ​
Effective Interest Rate as of March 31, 2022 | ​ |  |  | ​
Fixed rate (including hedged variable rate debt) | ​ |  | 2.25 | %
Variable rate | ​ |  | 0.91 | %
Effective interest rate | ​ |  | 2.06 | %

​

Our ratio of debt to total enterprise value was approximately 26% (based on the closing price of Digital Realty Trust, Inc.’s common stock on March 31, 2022 of $141.80). 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.’s 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 USD LIBOR, EURIBOR, SONIA, SORA, BBR, HIBOR, TIBOR, CDOR, and for Korean Won the base CD rates, depending on the respective agreement governing the debt, including our global revolving credit facilities. As of March 31, 2022, our debt had a weighted average term to initial maturity of approximately 6.0 years (or approximately 6.1 years assuming exercise of extension options).

As of March 31, 2022, our pro-rata share of secured debt of unconsolidated entities was approximately $813.2 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, 2022 to Three Months Ended March 31, 2021

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,
​ | 2022 |  | 2021 |  | Change
Net cash provided by operating activities | $ | 277,685 | ​ | $ | 327,875 | ​ | $ | (50,190)
Net cash (used in) provided by investing activities |  | (719,092) | ​ |  | 185,458 | ​ |  | (904,550)
Net cash provided by (used in) financing activities |  | 478,296 | ​ |  | (416,665) | ​ |  | 894,961
Net increase in cash, cash equivalents and restricted cash | $ | 36,889 | ​ | $ | 96,668 | ​ | $ | (59,779)

​

The changes in the activities that comprise the increase in net cash used in investing activities for the three months ended March 31, 2022 as compared to the three months ended March 31, 2021 consisted of the following amounts (in thousands).

​ | ​ | ​
​ | Change
Increase in cash used for improvements to investments in real estate | $ | (10,211)
Increase in cash contributed to investments in unconsolidated entities | ​ | (190,992)
Decrease in net cash provided by proceeds from sale of real estate | ​ | (685,484)
Other changes |  | (17,863)
Increase in net cash used in investing activities | $ | (904,550)

​

The decrease in net cash used in investing activities was primarily due to (i) sale of investments related to the sale of 11 data centers in Europe in March 2021, (ii) investments in various unconsolidated entities, and (iii) an increase in cash used for improvements to investments in real estate.

​

47

​

The changes in the activities that comprise the increase in net cash provided by financing activities for the three months ended March 31, 2022 as compared to the three months ended March 31, 2021 for the Company consisted of the following amounts (in thousands).

​ | ​ | ​
​ | Change
Increase in cash used in/provided by short-term borrowings | $ | 620,460
Decrease in cash provided by proceeds from secured / unsecured debt | ​ | (90,572)
Decrease in cash used for repayment on secured / unsecured debt | ​ | 436,959
Increase in cash used for dividend and distribution payments |  | (31,164)
Other changes | ​ | (40,722)
Increase in net cash provided by financing activities | $ | 894,961

​

The increase in net cash provided by financing activities was primarily due to (i) an increase in cash proceeds from short-term borrowings, (ii) a decrease in cash used for repayment of unsecured notes (in 2022, we redeemed the 4.750% Notes due 2025 ($450 million); in 2021 we redeemed 2.750% Notes due 2023 ($300 million) and paid down the remaining balance of our unsecured term loan ($537 million)), and (iii) an increase in dividend and distribution payments due to an increased dividend amount per share of common stock and common unit.

​

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, 2022, 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, 2022, 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.

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 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

48

​

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.

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, 2022, our consolidated debt was as follows (in millions):

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | ​ | ​ |  | Estimated Fair
​ | ​ | Carrying Value |  | Value
Fixed rate debt | ​ | $ | 13,199.6 | ​ | $ | 12,689.0
Variable rate debt subject to interest rate swaps | ​ |  | 2.3 | ​ |  | 2.3
Total fixed rate debt (including interest rate swaps) | ​ |  | 13,201.9 | ​ |  | 12,691.3
Variable rate debt | ​ |  | 1,307.1 | ​ |  | 1,307.1
Total outstanding debt | ​ | $ | 14,509.0 | ​ | $ | 13,998.4

​

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, 2022:

​ | ​ | ​ | ​
​ |  | Change
Assumed event | ​ | ($ millions)
Increase in fair value of interest rate swaps following an assumed 10% increase in interest rates | ​ | $ | (0.0)
Decrease in fair value of interest rate swaps following an assumed 10% decrease in interest rates | ​ |  | 0.0
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 | ​ |  | 2.9
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 | ​ |  | (2.9)
Increase in fair value of fixed rate debt following a 10% decrease in interest rates | ​ |  | 138.7
Decrease in fair value of fixed rate debt following a 10% increase in interest rates | ​ |  | (129.8)

​

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 and Singapore dollar. As a result of the Ascenty entity and deconsolidation of Ascenty, 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.

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

The Operating Partnership 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 the chief executive officer and chief financial officer of its general partner, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, the Operating Partnership’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 Operating Partnership has investments in certain unconsolidated entities, which are accounted for using the equity method of accounting. As the Operating Partnership 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 Operating Partnership carried out an evaluation, under the supervision and with participation of the chief executive officer and chief financial officer of its general partner, 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 chief executive officer and chief financial officer of the Operating Partnership’s general partner concluded that its disclosure controls and procedures were effective at the reasonable assurance level.
