EXPLANATORY NOTE

This report combines the annual reports on Form 10-K for the year ended December 31, 2021 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 December 31, 2021, the Parent owned an approximate 98.0% common general partnership interest in Digital Realty Trust, L.P. The remaining approximate 2.0% 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 December 31, 2021, 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 annual reports on Form 10-K 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 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.

PART I

Item 1. BUSINESS

The Company

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 Operating Partnership, (collectively, “we”, “our”, “us” or the “Company”) is a leading global provider of data center, colocation and interconnection solutions for customers across a variety of industry verticals. The Parent operates as a REIT for federal income tax purposes. The OP is the entity through which the Parent conducts its business of owning, acquiring, developing and operating data centers. The Parent was incorporated in the state of Maryland on March 9, 2004. The OP was organized as a limited partnership in the state of Maryland on July 21, 2004.

As of December 31, 2021, our portfolio consisted of 287 data centers (including 50 data centers held as investments in unconsolidated entities), of which 127 are located in the United States, 107 are located in Europe, 27 are located in Latin America, 13 are located in Asia, six are located in Australia, four are located in Africa and three are located in Canada.

Our principal executive offices are located at 5707 Southwest Parkway, Building 1, Suite 275, Austin, Texas 78735. Our telephone number is (737) 281-0101. Our website is www.digitalrealty.com. The information found on, or otherwise accessible through, our website is not incorporated by reference into, nor does it form a part of, this Annual Report on Form 10-K.

Recent Acquisitions

On October 29, 2019, Digital Realty Trust, Inc., Digital Intrepid Holding B.V., an indirect subsidiary of Digital Realty Trust, Inc. (the “Buyer”), and Interxion Holding N.V., which we refer to as Interxion, entered into a purchase agreement, or the Purchase Agreement, pursuant to which, subject to the terms and conditions of the Purchase Agreement, the Buyer commenced an exchange offer to purchase all of the outstanding ordinary shares of Interxion in exchange for shares of common stock of Digital Realty Trust, Inc. We refer to the transactions contemplated by the Purchase Agreement as the Interxion Combination. We obtained control of Interxion on March 9, 2020 and completed the Interxion Combination on March 12, 2020 for total equity consideration of approximately $7.0 billion, including cash assumed. The Interxion Combination expanded the combined company’s presence across Europe and Africa.

On November 1, 2019, we closed the joint venture with Mapletree Investments and Mapletree Industrial Trust, which we refer to collectively as Mapletree, on three existing Turn-Key Flex® data centers located in Ashburn, Virginia. The Company retained a 20% ownership interest in the joint venture, and Mapletree acquired the remaining 80% stake for approximately $0.8 billion. We will continue to operate and manage these facilities. The second tranche of the Mapletree transaction, the sale of 10 fully-leased Powered Base Building® properties for $557 million, closed in January 2020.

On December 20, 2018, the Operating Partnership and Stellar Participações S.A. (formerly Stellar Participações Ltda.), a Brazilian subsidiary of the Operating Partnership, completed the acquisition of Ascenty, a leading data center provider in Brazil, for cash and equity consideration of approximately $2.0 billion, including cash assumed. We refer to this transaction as the Ascenty Acquisition. In March 2019, we formed a joint venture with Brookfield Infrastructure, an affiliate of Brookfield Asset Management, one of the largest owners and operators of infrastructure assets globally. Brookfield invested approximately $702 million in exchange for approximately 49% of the total equity interests in the joint venture which owns and operates Ascenty. A subsidiary of the Operating Partnership retained the remaining equity interest in the Ascenty joint venture. As of March 27, 2019, we deconsolidated Ascenty and recorded our retained interest as an investment in unconsolidated entities due to shared control with Brookfield.

Industry Background

The digital economy continues to grow and change how enterprises across all industries create and deliver value. Companies increasingly need to operate ubiquitously, on-demand and with real-time intelligence serving customers, partners and employees across multiple channels, business functions and points of business presence. Computational processing power requirements continue to advance, data traffic is growing, and the volume of data that enterprises generate, transmit, process, analyze, monitor and manage is expanding dramatically. The Internet of Things, 5G, autonomous vehicles and artificial intelligence, among other technological advancements, are driving this digital transformation.

We believe that enterprise data growth is accelerating due to the growing digital economy and emerging technological advances. As enterprises analyze and process this accelerating data mass, they create more data. As this mass of data continues to grow, it needs to be analyzed and processed: a task which we believe is becoming increasingly challenging to replicate and relocate. This phenomenon is called Data Gravity. We believe that enterprise decisionmakers will need to increasingly consider the impact of how Data Gravity impacts their enterprise IT architectures and, accordingly, we have developed the Data Gravity Index™: a global forecast that measures the intensity and gravitational force of enterprise data growth.

As the largest global provider of cloud- and carrier-neutral data center, colocation and interconnection solutions, we believe the data center industry is poised for sustainable growth. The demand for data center infrastructure is being driven by this digital transformation which is contributing to the explosive growth of data, rapid growth of cloud adoption and greater demand for IT outsourcing. The power requirements and financial costs to support this growth in data, traffic and storage are substantial and growing accordingly. We believe data centers will continue to play a critical role in the digital economy and enabling business transformation strategies.

We believe cloud solutions and hybrid cloud solutions will remain significant drivers of demand for data center infrastructure. The hybrid cloud, which combines public and private cloud solutions, has gained traction because it enables corporate enterprises to achieve efficiencies and contain costs, as well as scale and secure their most sensitive information. In addition, the leading cloud service providers are generally mature, well-capitalized technology companies, and cloud platforms are among the fastest-growing business segments. Data center providers that can solve global coverage, capacity and connectivity needs, and coordinate and aggregate diverse customer and application demand, are poised to benefit from these cloud-specific industry drivers.

These diverse and secular industry dynamics are driving greater demand for data center capacity not only from global cloud service providers, but also from businesses across other industries, including IT service firms, social media, content providers and the financial services sector. As companies focus on their core competencies and rely on outsourcing to meet their IT infrastructure needs, they are prioritizing colocation for their data center solutions for various reasons, including to reduce latency in data transfer and increase global presence and connectivity. New technologies need a fast, reliable and flexible foundation to operate, and the importance of offering a full spectrum of power, space and connectivity solutions continues to grow.

Our Business

We provide a global data center platform that supports our customers’ digital infrastructure and enables our customers to interconnect with their customers and partners. We solve global coverage, capacity and connectivity needs for companies of

​

●Our data centers may not be suitable for re-leasing without significant expenditures or renovations.
●We may be unable to lease vacant or development space, renew leases, or re-lease space as leases expire.
●Even if we have additional space available for lease at any one of our data centers, our ability to lease this space to existing or new customers could be constrained by our ability to provide sufficient electrical power.
●Our portfolio depends upon local economic conditions and is geographically concentrated in certain locations.
●We and our customers may experience supply chain or procurement disruptions, or increased supply chain costs, which may lead to delays.
●We lease or sublease certain of our data center space from third parties and the ability to retain these leases or subleases could be a significant risk to our ongoing operations.
●We may not be able to adapt to changing technologies and customer requirements, and our data center infrastructure may become obsolete.
●We depend upon third-party suppliers for power, and we are vulnerable to service failures and to price increases by such suppliers and to volatility in the supply and price of power in the open market.
●We depend on third parties to provide network connectivity to the customers in our data centers and any delays or disruptions in connectivity may materially adversely affect our operating results and cash flow.
●Our international activities, including acquisition, ownership and operation of data centers located outside of the United States, subject us to risks different than those we face in the United States and we may not be able to effectively manage our international business.
●The United Kingdom’s withdrawal from the European Union may have a negative effect on global economic conditions, financial markets and our business.
●Our recent acquisitions may not achieve the intended benefits or may disrupt our plans and operations.
●We may be subject to unknown or contingent liabilities related to our recent acquisitions, for which we may have no or limited recourse against the sellers.
●We may be unable to identify, including sourcing off-market deal flow, and complete acquisitions on favorable terms or at all.
●Joint venture (JV) investments could be adversely affected by our lack of sole decision-making authority, our reliance on our JV partners’ financial condition and disputes between us and our JV partners.
●Brazilian political and economic conditions could adversely affect our investment in the Ascenty joint venture.
●Any delays or unexpected costs in the development of our existing space and developable land and new properties acquired for development may delay and harm our growth prospects, future operating results and financial condition.
●Discontinuation, reform or replacement of the London Interbank Offered Rate (LIBOR) and other benchmark rates, or uncertainty related to the potential for any of the foregoing, may adversely affect our business.
●We have substantial debt and face risks associated with the use of debt to fund our business activities, including refinancing and interest rate risks.
●Our growth depends on external sources of capital which are outside of our control.
●Declining real estate valuations, impairment charges and illiquidity of real estate investments could adversely affect our earnings and financial condition.
●Our success depends on key personnel whose continued service is not guaranteed.

For a complete discussion of forward-looking statements, see the section in this report entitled “Forward-Looking Statements.”

A discussion regarding our financial condition and results of operations for 2021 as compared to 2020 is presented herein. Information on 2019 is presented in graphs and other tables only to show year-over-year trends in our results of operations and operating metrics. Our financial condition for 2019 and results of operations for 2019 – and also 2019 as compared to 2020 – can be found under Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, of our Annual Report on form 10-K for the fiscal year ended 2020, filed with the SEC on March 1, 2021.

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 our Operating Partnership’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. We focus exclusively on owning, acquiring, developing and operating data centers because we believe that the growth in data center demand and the technology-related real estate industry generally will continue to outpace the overall economy.

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.

Summary of 2021 Significant Activities

We completed the following significant activities in 2021 as described in the Notes to the Consolidated Financial Statements:

●In January, we issued and sold €1.0 billion aggregate principal amount of 0.625% Guaranteed Notes due 2031 (the “2031 Notes”). The 2031 Notes are senior unsecured obligations of Digital Intrepid Holding B.V. (a wholly-owned subsidiary of the OP) and are fully and unconditionally guaranteed by the Parent and the OP. Net proceeds from the offering were approximately €988.3 million (approximately $1,206.4 million based on the exchange rate on the issuance date of January 12, 2021) after deducting managers’ discounts and estimated offering expenses.
●In February, we redeemed €350 million of 2.750% notes due in 2023. As part of this redemption, we recorded a $17.5 million loss on extinguishment of debt.
●In March, we sold a portfolio of 11 data centers in Europe to Ascendas Reit, a CapitaLand sponsored REIT, for total consideration of approximately $680.0 million. The total gain recorded as a result of this sale was approximately $332.0 million.
●In May, we redeemed all of the Parent’s outstanding Series C cumulative redeemable perpetual preferred stock for $25.21 per share, or a redemption price of $25.00 per share, plus accrued and unpaid dividends up to but not including the redemption date (the “Series C Preferred Share Redemption”). The transaction resulted in a gain on redemption of $18.0 million. This amount is reflected as gain on redemption of preferred stock which increased net income available to common stockholders.
●In July, we issued and sold CHF 275 million aggregate principal amount of 0.20% guaranteed notes due 2026 and CHF 270 million aggregate principal amount of 0.55% guaranteed notes due 2029 (collectively referred to as, “the Swiss Franc Notes”). Net proceeds from the offering were approximately CHF 542.3 million (approximately $591 million based on the exchange rate on the issuance date of July 15, 2021). The net proceeds are intended to finance or refinance, in whole or in part, recently completed or future green building, energy and resource efficiency and renewable energy projects.
●In August, an existing unconsolidated joint venture between the Company and PGIM Real Estate (the “PGIM Joint Venture”) completed the sale of a portfolio consisting of 10 data centers in North America for $581 million – which resulted in a gain on sale of assets for the joint venture. Our portion of the gain was $64 million and included as a component of Equity in Unconsolidated Entities in our consolidated income statements. In connection with completion of the sale, we also received a $19 million promote fee related to the partnership exceeding certain investor return thresholds over the life of the partnership. The amount received is included in fee income and other in our consolidated income statements.

| | ● | In September, we completed an underwritten public offering of 6,250,000 shares of the Parent’s common stock, all of which were offered in connection with forward sale agreements we entered into with certain financial institutions acting as forward purchasers. The forwar

Item 7A. 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.

Sensitivity to Changes in Interest Rates

The following table shows the effects if assumed changes in interest rates occurred, based on fair values and interest expense as of December 31, 2021:

​

​​​​

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​0.2
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​(0.2)
Increase in fair value of fixed rate debt following a 10% decrease in interest rates​17.6
Decrease in fair value of fixed rate debt following a 10% increase in interest rates​(24.5)

​

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.

Management’s Report on Internal Control over Financial Reporting

The management of Digital Realty Trust, Inc. (the Company) is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15(d)-15(f). Our internal control system was designed to provide reasonable assurance to the Company’s management and board of directors regarding the preparation and fair presentation of published financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, we assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2021. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework (2013). We acquired Interxion and subsidiaries during the year ended December 31, 2021. Based on our assessment, management concluded that as of December 31, 2021, the Company’s internal control over financial reporting was effective based on those criteria.

Our independent registered public accounting firm has issued an audit report on the Company’s internal control over financial reporting. This report appears on page 83.

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 December 31, 2021. Based on the foregoing, the Company’s management concluded that its disclosure controls and procedures were effective at the reasonable assurance level.
