The aggregate market value of the common equity held by non-affiliates of Digital Realty Trust, Inc. as of
June 28, 2013 totaled approximately $7.8 billion based on the closing price for Digital Realty Trust, Inc.s common stock on that day as reported by the New York Stock Exchange. Such value excludes common stock held by executive officers,
directors and 10% or greater stockholders as of June 28, 2013. The identification of 10% or greater stockholders as of June 28, 2013 is based on Schedule 13G and amended Schedule 13G reports publicly filed before June 28, 2013. This
calculation does not reflect a determination that such parties are affiliates for any other purposes.

There is no public
trading market for the common units of Digital Realty Trust, L.P. As a result, the aggregate market value of the common units held by non-affiliates of Digital Realty Trust, L.P. cannot be determined.

Indicate the number of shares outstanding of each of the registrants classes of common stock, as of the latest practicable date.

This Amendment No. 1 (Amendment No. 1) on Form 10-K/A amends the combined Annual Report on Form 10-K for the fiscal

EXPLANATORY NOTE

This report combines the annual reports on Form 10-K for the year ended December 31, 2013 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 indicated or
unless the context requires otherwise, all references to our operating partnership or the operating partnership refer to Digital Realty Trust, L.P. together with its consolidated subsidiaries.

Digital Realty Trust, Inc. is a real estate investment trust, or REIT, and the sole general partner of Digital Realty Trust, L.P. As
of December 31, 2013, Digital Realty Trust, Inc. owned an approximate 97.7% common general partnership interest in Digital Realty Trust, L.P. The remaining approximate 2.3% common limited partnership interests are owned by non-affiliated
investors and certain directors and officers of Digital Realty Trust, Inc. As of December 31, 2013, Digital Realty Trust, Inc. 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., Digital Realty Trust, Inc. has the full, exclusive and complete responsibility for the operating partnerships day-to-day management and control.

We believe combining the annual reports on Form 10-K of Digital Realty Trust, Inc. and Digital Realty Trust, L.P. into this single
report results in the following benefits:



| |  |  | enhancing investors understanding of our company and our operating partnership 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 our company and our operating partnership; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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

There are a few differences between our company and our operating partnership, which are reflected in the disclosure in this report. We
believe it is important to understand the differences between our company and our operating partnership in the context of how we operate as an interrelated consolidated company. Digital Realty Trust, Inc. is a REIT, whose only material asset is its
ownership of partnership interests of Digital Realty Trust, L.P. As a result, Digital Realty Trust, Inc. does not conduct business itself, other than acting as the sole general partner of Digital Realty Trust, L.P., issuing public equity from
time to time and guaranteeing certain unsecured debt of Digital Realty Trust, L.P. and certain of its subsidiaries. Digital Realty Trust, Inc. itself does not issue any indebtedness but guarantees the unsecured debt of Digital Realty Trust, L.P. and
certain of its subsidiaries, as disclosed in this report. Digital Realty Trust, L.P. holds substantially all the assets of the company and holds the ownership interests in the companys joint ventures. Digital Realty Trust, L.P. conducts
the operations of the business and is structured as a partnership with no publicly traded equity. Except for net proceeds from public equity issuances by Digital Realty Trust, Inc., which are generally contributed to Digital Realty Trust, L.P. in
exchange for partnership units, Digital Realty Trust, L.P. generates the capital required by the companys business through Digital Realty Trust, L.P.s operations, by Digital Realty Trust, L.P.s direct or indirect incurrence of
indebtedness or through the issuance of partnership units.

The presentation of noncontrolling interests in operating
partnership, stockholders equity and partners capital are the main areas of difference between the consolidated financial statements of Digital Realty Trust, Inc. and those of Digital Realty Trust, L.P. The common limited partnership
interests held by the limited partners in Digital Realty Trust, L.P. are presented as limited partners capital within partners capital in Digital Realty Trust, L.P.s consolidated financial statements and as noncontrolling interests
in operating partnership within equity in Digital Realty Trust, Inc.s consolidated financial statements. The common and preferred partnership interests held by Digital Realty Trust, Inc. in Digital Realty Trust, L.P. are presented as general
partners capital within partners capital in Digital Realty Trust, L.P.s consolidated financial statements and as preferred stock, common stock, additional paid-in capital and accumulated dividends in excess of earnings within
stockholders

equity in Digital Realty Trust, Inc.s consolidated financial statements. The differences in the presentations between stockholders equity and partners capital result from the
differences in the equity issued at the Digital Realty Trust, Inc. and the Digital Realty Trust, L.P. levels.

To help
investors understand the significant differences between the company and the operating partnership, this report presents the following separate sections for each of the company and the operating partnership:



| |  |  | consolidated financial statements;
| | - |  | ----------------------------------



| |  |  | the following notes to the consolidated financial statements:
| | - |  | -------------------------------------------------------------



| |  |  | Debt of the company and Debt of the operating partnership;
| | - |  | ----------------------------------------------------------



| |  |  | Income per Share and Income per Unit;
| | - |  | -------------------------------------



| |  |  | Equity and Accumulated Other Comprehensive Loss, Net of the company and Capital and Accumulated Other Comprehensive Income (Loss) of the operating
partnership; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Quarterly Financial Information;
| | - |  | --------------------------------



| |  |  | Liquidity and Capital Resources in Managements Discussion and Analysis of Financial Condition and Results of Operations;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | Market for Registrants Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities; and
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | Selected Financial Data.
| | - |  | ------------------------

This report also includes separate Item 9A. Controls and Procedures sections and separate Exhibit 31 and 32 certifications for each of the company and the operating partnership in order to
establish that the Chief Executive Officer and the Chief Financial Officer of each entity have made the requisite certifications and that the company and the operating partnership are compliant with Rule 13a-15 or Rule 15d-15 of the Securities
Exchange Act of 1934 and 18 U.S.C. §1350.

In order to highlight the differences between the company and the operating
partnership, the separate sections in this report for the company and the operating partnership specifically refer to the company and the operating partnership. In the sections that combine disclosure of the company and the operating partnership,
this report refers to actions or holdings as being actions or holdings of the company. Although the operating partnership is generally the entity that enters into contracts and joint ventures and holds assets and debt, reference to the company is
appropriate because the business is one enterprise and the company operates the business through the operating partnership.

As general partner with control of the operating partnership, Digital Realty Trust, Inc. consolidates the operating partnership for
financial reporting purposes, and it does not have significant assets other than its investment in the operating partnership. Therefore, the assets and liabilities of Digital Realty Trust, Inc. and Digital Realty Trust, L.P. are the same on their
respective consolidated financial statements. The separate discussions of Digital Realty Trust, Inc. and Digital Realty Trust, L.P. 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.

General

We own, acquire, develop and manage technology-related real estate. We target high-quality, strategically located properties containing
applications and operations critical to the day-to-day operations of technology industry tenants and corporate enterprise datacenter users, including the information technology, or IT, departments of Fortune 100 and financial services companies. Our
tenant base is diversified within the technology industry and reflects a broad spectrum of regional, national and international tenants that are leaders in their respective areas. Digital Realty Trust, L.P., a Maryland limited partnership, is the
entity through which Digital Realty Trust, Inc., a Maryland corporation, conducts its business and owns its assets. Digital Realty Trust, Inc. operates as a REIT for federal income tax purposes.

As of December 31, 2013, our portfolio consisted of 131 properties, including 12 properties held as investments in unconsolidated
joint ventures and developable land, of which, 104 are located throughout North America, 22 are located in Europe, three are located in Australia and two are located in Asia. We are diversified, with a presence in several major markets where
corporate data center and technology tenants are concentrated, including the Boston, Chicago, Dallas, Los Angeles, New York Metro, Northern Virginia, Phoenix, San Francisco and Silicon Valley metropolitan areas in the United States, the Amsterdam,
Dublin, London and Paris markets in Europe and the Singapore, Sydney, Melbourne, Hong Kong and Osaka markets in the Asia Pacific region. Our properties contain a total of approximately 24.5 million net rentable square feet, including
approximately 1.8 million square feet of space under active development, which includes current base building and data center projects in progress, and approximately 1.3 million square feet of space held for future development, which includes
space held for future data center development and excludes space under active development. A significant component of our current and future internal growth is anticipated through the development of our existing active development space and space
held for future development and through acquisitions of new properties. As of December 31, 2013, our portfolio, including the 12 properties held as investments in unconsolidated joint ventures and excluding active development space and space
held for development, was approximately 92.6% leased. The types of properties within our focus include:



| |  |  | Internet gateway datacenters, which serve as hubs for Internet and data communications within and between major metropolitan areas;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------



| |  |  | Corporate datacenters, which provide secure, continuously available environments for the storage and processing of critical electronic information.
Data centers are used for disaster recovery purposes, transaction processing and to house corporate IT operations;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Technology manufacturing properties, which contain highly specialized manufacturing environments for such purposes as semiconductor manufacturing and
specialty pharmaceutical manufacturing; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Regional or national offices of technology companies that are located in our target markets.
| | - |  | --------------------------------------------------------------------------------------------

Unlike traditional office and flex/research and development space, the location of and improvements to our facilities are generally
essential to our tenants businesses, which we believe results in high occupancy levels, long lease terms and low tenant turnover. In addition, many of our properties have tenant improvements that have been installed at our tenants
expense. The tenant improvements in our facilities are generally readily adaptable for use by similar tenants.

Digital Realty
Trust, Inc. was incorporated in the state of Maryland on March 9, 2004. Digital Realty Trust, L.P. was organized in the state of Maryland on July 21, 2004. Our principal executive offices are located at Four Embarcadero Center, Suite
3200, San Francisco, California 94111. Our telephone number at that location is (415) 738-6500. Our website is located at www.digitalrealty.com. The information found on, or otherwise accessible through, our website is not incorporated
into, and does not form a part of, this annual report or any other report or document we file with or furnish to the U.S. Securities and Exchange Commission, or the SEC.

Our Competitive Strengths

We believe we distinguish ourselves from other owners, acquirors and managers of technology-related real estate through our competitive strengths, which include:



| |  |  | High-Quality Portfolio that is Difficult to Replicate.Our portfolio contains state-of-the-art data center facilities with extensive tenant
improvements. Based on current market rents and the estimated replacement costs of our properties and their improvements, we believe that they could not be replicated today on a cost-competitive basis. Our portfolio of data center facilities is
equipped to meet the power and cooling requirements for the most demanding corporate IT applications. Many of the properties in our portfolio are located on major aggregation points formed by the physical presence of multiple major
telecommunications service providers, which reduces our tenants costs and operational risks and increases the attractiveness of our buildings.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Presence in Key Markets.Our portfolio is located in 33 metropolitan areas, including the Boston, Chicago, Dallas, Los Angeles, New York Metro,
Northern Virginia, Phoenix, San Francisco and Silicon Valley metropolitan areas in the United States, the Amsterdam, Dublin, Geneva, London and Paris markets in Europe and the Singapore, Sydney, Melbourne, Hong Kong and Osaka markets in the Asia
Pacific region, and is diversified so that no one market represented more than 12.0% of the aggregate annualized rent of our portfolio as of December 31, 2013. See Managements Discussion and Analysis of Financial Condition and
Results of OperationsOverviewRevenue Base.

| |  |  | Proven Experience Executing New Leases.We have considerable experience in identifying and leasing to new tenants. The combination of our
specialized data center leasing team and customer referrals continues to provide a robust pipeline of new tenants. During the year ended December 31, 2013, we commenced new leases totaling approximately 1.0 million square feet, which
represent approximately $120.6 million in annualized GAAP rent. During the year ended December 31, 2013, we signed new leases totaling approximately 1.3 million square feet, which represent approximately $161.3 million in annualized GAAP rent. These
leases were comprised of Powered Base Buildings®, Turn-Key
Flex® space, Custom Solutions product and space for ancillary office and other uses.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Demonstrated Acquisition Capability.As of December 31, 2013, our portfolio consisted of 131 properties, including 12 properties held
as investments in unconsolidated joint ventures and developable land, for an aggregate of 24.5 million net rentable square feet, including approximately 1.8 million square feet of space under active development and approximately 1.3
million square feet of space held for future development. We have developed detailed, standardized procedures for evaluating acquisitions, including income producing assets and vacant properties and land suitable for development, to ensure that they
meet our financial, technical and other criteria. These procedures and our in-depth knowledge of the technology and data center industries allow us to identify strategically located properties and evaluate investment opportunities efficiently and,
as appropriate, commit and close quickly. Our broad network of contacts within a highly fragmented universe of sellers and brokers of technology-related real estate enables us to capitalize on acquisition opportunities. As a result, we acquired a
substantial portion of our properties before they were broadly marketed by real estate brokers.

| |  |  | Flexible Datacenter Solutions.We provide flexible, customer oriented solutions designed to meet the needs of domestic and international
companies across multiple industry verticals, including Turn-Key Flex®, Powered Base Building® and Custom Solutions options. Our Turn-Key Flex® data centers are move-in ready, physically secure facilities with the power and cooling capabilities to support mission-critical IT enterprise applications. We
believe our Turn-Key Flex® facilities are effective solutions for tenants that lack the expertise, capital
budget or desire to provide their own extensive data center infrastructure, management and security. For tenants that possess the ability to build and operate their own facility, our Powered Base Building® solution provides the physical location, required power and network access necessary to support a state-of-the-art
data center. Our in-house engineering and design and construction professionals can also provide tenants with our Custom Solutions product to meet their unique specifications. Our Critical Facilities Management® services and team of technical engineers and data center operations experts provide 24/7 support for these
mission-critical facilities.

| |  |  | Differentiating Development Advantages.Our extensive development activity, operating scale and process-based approach to data center design,
construction and operations result in significant cost savings and added value for our tenants. We have leveraged our purchasing power by securing global purchasing agreements and developing relationships with major equipment manufacturers, reducing
costs and shortening delivery timeframes on key components, including major mechanical and electrical equipment. Utilizing our innovative modular data center design referred to as POD Architecture®, we deliver what we believe to be a technically superior data center environment at significant cost savings. In addition, by utilizing our POD Architecture® to develop new Turn-Key Flex® facilities in our existing Powered Base
Building® facilities, on average we are able to deliver a fully commissioned facility in just under 30 weeks.
Finally, our access to capital allows us to provide data center solutions for tenants that do not want to invest their own capital.

| |  |  | Diverse Tenant Base Across a Variety of Industry Sectors.We use our in-depth knowledge of the requirements and trends for Internet and data
communications and corporate data center users to market our properties to domestic and international tenants with specific technology needs. At December 31, 2013, we had 655 tenants across a variety of industry verticals, ranging from
financial services, cloud and information technology services, to manufacturing, energy, health care and consumer products. Our largest tenant, comprised of subsidiaries of CenturyLink, Inc., accounted for approximately 7.8% of the aggregate
annualized rent of our portfolio as of December 31, 2013 and no other single tenant accounted for more than approximately 5.5% of the aggregate annualized rent of our portfolio.

| |  |  | Experienced and Committed Management Team and Organization.Our senior management team has an average of 30 years of experience in the
technology or real estate industries, including experience as investors in, advisors to and founders of technology companies. We believe that our senior management teams extensive knowledge of both the real estate and the technology industries
provides us with a key competitive advantage. At December 31, 2013, our senior management team and directors collectively owned common equity interests in our company of approximately 0.7%, which aligns their interests with those of our
stockholders.

Business and Growth Strategies

Our primary business objectives are to maximize sustainable long-term growth in earnings and funds from operations per share and unit and
to maximize cash flow and returns to our stockholders and our operating partnerships unitholders, including through the payment of distributions. Our business strategies to achieve these objectives are:



| |  |  | Achieve Superior Returns on Development Inventory.At December 31, 2013, we had approximately 1.8 million square feet of space under
active development for Turn-Key Flex®, Powered Base Building® and Custom Solutions products, all of which are expected to be income producing on or after completion, in eight U.S. markets, three European markets, one Canadian
market and one Australian market, consisting of approximately 1,063,000 square feet of base building construction and 697,000 square feet of data center construction. We may continue to build out our development portfolio when justified by
anticipated returns.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Capitalize on Acquisition Opportunities. We believe that acquisitions enable us to increase cash flow and create long-term stockholder
value. Our relationships with corporate information technology groups, technology tenants and real estate brokers who are dedicated to serving these tenants provide us with ongoing access to potential acquisitions and often enable us to avoid
competitive bidding. Furthermore, the specialized nature of technology-related real estate makes it more difficult for traditional real estate investors to understand, which results in reduced competition for acquisitions relative to other property
types. We believe this dynamic creates an opportunity for us to obtain better risk-adjusted returns on our capital.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Access and Use Capital Efficiently.We believe we can increase stockholder returns by effectively accessing and deploying capital. Since Digital
Realty Trust, Inc.s initial public offering in 2004, our company has raised approximately $11.7 billion of capital through common, preferred and convertible preferred equity offerings, exchangeable debt offerings, non-exchangeable bond
offerings, our global revolving credit facility, our term loan facility, the Prudential shelf facility, secured mortgage financings and refinancings and sales of non-core assets. We will endeavor to maintain financial flexibility while using our
liquidity and access to capital to support operations, including our acquisition, leasing and development programs, which are important sources of our growth.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Maximize the Cash Flow of Our Properties. We aggressively manage and lease our assets to increase their cash flow. We often acquire
properties with substantial in-place cash flow and some vacancy, which enables us to create upside through lease-up. Moreover, many of our properties contain extensive in-place infrastructure or buildout that may result in higher rents when leased
to tenants seeking these improvements. We control our costs by negotiating expense pass-through provisions in tenant leases for operating expenses, including power costs and certain capital expenditures. Leases covering approximately 75% of the
leased net rentable square feet in our portfolio as of December 31, 2013 required tenants to pay all or a portion of increases in operating expenses, including real estate taxes, insurance, common area charges and other expenses.

technology groups and technology-intensive companies to identify and comprehensively respond to their real estate needs. Our companys leasing and sales

Competition

We compete with numerous developers, owners and operators of real estate and datacenters, many of which own properties similar to ours in the same markets in which our properties are located, including
DuPont Fabros Technology, Inc., CoreSite Realty Corporation, CyrusOne Inc., QTS Realty Trust, Inc. and various local developers in the U.S., as well as Global Switch Holdings Limited and various regional operators in Europe, Asia and Australia. If
our competitors offer space that our tenants or potential tenants perceive to be superior to ours based on numerous factors, including available power, security considerations, location, or connectivity, or if they offer rental rates below current
market rates, or below the rental rates we are offering, we may lose tenants or potential tenants or be required to incur costs to improve our properties or reduce our rental rates. In addition, recently many of our competitors have developed
additional datacenter space. If the supply of datacenter space continues to increase as a result of these activities or otherwise, rental rates may be reduced or we may face delays in leasing or be unable to lease our vacant space, including space
that we develop. Finally, if tenants or potential tenants desire services that we do not offer, we may not be able to lease our space to those tenants. Our financial condition, results of operations, cash flow, cash available for distribution and
ability to satisfy our debt service obligations could be materially adversely affected as a result of any or all of these factors.

Geographic Information

Operating revenues from properties in the United States were $1.1 billion, $1.1 billion and $946.0 million and outside the United
States were $349.1 million, $228.9 million and $116.7 million for the years ended December 31, 2013, 2012 and 2011, respectively. We had long-lived assets located in the United States of $5.6 billion, $5.0 billion and $4.3
billion and outside the United States of $2.7 billion, $2.5 billion and $1.0 billion as of December 31, 2013, 2012 and 2011, respectively.

Operating revenues from properties located in the United Kingdom were $197.0 million, $117.2 million and $43.6 million, or 13.3%, 9.2% and 4.1% of total operating revenues, for the years ended
December 31, 2013, 2012 and 2011, respectively. No other foreign country comprised more than 10% of total operating revenues for each of these years. We had long-lived assets located in the United Kingdom of $1.8 billion, $1.7 billion and
$356.0 million, or 21.1%, 22.3% and 6.8% of total long-lived assets, as of December 31, 2013, 2012 and 2011, respectively. No other foreign country comprised more than 10% of total long-lived assets as of each of December 31, 2013, 2012
and 2011. See Risk FactorsOwnership of properties located outside of the United States subjects us to foreign currency and related risks which may adversely impact our ability to make distributions, Our
international activities are subject to special risks different than those faced by us in the United States and we may not be able to effectively manage our international business and We face risks with our international
acquisitions associated with investing in unfamiliar markets for risks relating to our foreign operations.

Regulation

General

Office properties in our markets are subject to various laws, ordinances and regulations, including regulations relating to common areas. We believe that each of our properties as of December 31,
2013 has the necessary permits and approvals to operate its business.

Americans With Disabilities Act

Our properties must comply with Title III of the Americans with Disabilities Act of 1990, or the ADA, to the extent that such properties
are public accommodations as defined by the ADA. The ADA may require



5



---

##### Table of Contents

removal of structural barriers to access by persons with disabilities in certain public areas of our properties where such removal is readily achievable. We believe that our properties are in
substantial compliance with the ADA and that we will not be required to make substantial capital expenditures to address the requirements of the ADA. However, noncompliance with the ADA could result in imposition of fines or an award of damages to
private litigants. The obligation to make readily achievable accommodations is an ongoing one, and we will continue to assess our properties and to make alterations as appropriate in this respect.

Environmental Matters

Under various laws relating to the protection of the environment, a current or previous owner or operator of real estate may be liable for contamination resulting from the presence or discharge of
hazardous or toxic substances at that property, and may be required to investigate and clean up such contamination at or emanating from that property. Such laws often impose liability without regard to whether the owner or operator knew of, or was
responsible for, the presence of the contaminants, and the liability may be joint and several. Previous owners used some of our properties for industrial and retail purposes, and those properties may contain some level of environmental
contamination. Fuel storage tanks are present at many of our properties, and if releases were to occur, we may be liable for the costs of cleaning any resulting contamination. The presence of contamination or the failure to remediate contamination
at our properties may expose us to third-party liability or materially adversely affect our ability to sell, lease or develop the real estate or to borrow using the real estate as collateral.

Some of the properties may contain asbestos-containing building materials. Environmental laws require that asbestos-containing building
materials be properly managed and maintained, and may impose fines and penalties on building owners or operators for failure to comply with these requirements. These laws may also allow third parties to seek recovery from owners or operators for
personal injury associated with exposure to asbestos-containing building materials.

In addition, some of our tenants,
particularly those in the biotechnology and life sciences industry and those in the technology manufacturing industry, routinely handle hazardous substances and wastes as part of their operations at our properties, including chemical solvents,
medical waste, hydrocarbons, batteries and pesticides. Environmental laws and regulations subject our tenants, and potentially us, to liability resulting from these activities or from previous industrial or retail uses of those properties.
Environmental liabilities could also affect a tenants ability to make rental payments to us. We require our tenants to comply with these environmental laws and regulations and to indemnify us for any related liabilities.

Independent environmental consultants have conducted Phase I or similar environmental site assessments on all of the properties in our
portfolio. Site assessments are intended to discover and evaluate information regarding the environmental condition of the surveyed property and surrounding properties. These assessments do not generally include soil samplings, subsurface
investigations or an asbestos survey. None of the recent site assessments revealed any past or present environmental liability that we believe would have a material adverse effect on our business, assets, results of operations or our competitive
position. However, the assessments may have failed to reveal all environmental conditions, liabilities or compliance concerns. Material environmental conditions, liabilities or compliance concerns may have arisen after the review was completed or
may arise in the future; and future laws, ordinances or regulations may impose material additional environmental liability.

Our properties and their uses often require permits from various government agencies, including permits related to zoning and land use,
such as permits to operate data center facilities. Certain permits from state or local environmental regulatory agencies, including regulators of air quality, are usually required to install and operate diesel-powered generators, which provide
emergency back-up power at some of our facilities. These permits often set emissions limits for certain air pollutants, including oxides of nitrogen. In addition, various federal, state, and local environmental, health and safety requirements, such
as fire requirements and treated and storm water discharge requirements, apply to some of our properties. Changes to applicable regulations, such as air quality regulations, or the permit requirements for equipment at our facilities, could hinder or
prevent our construction or operation of data center facilities.

##### Table of Contents

The environmental laws and regulations to which our properties are subject may change in the
future, and new laws and regulations may be created. Such laws include those directly regulating our climate change impacts and those which regulate the climate change impacts of companies with which we do business, such as utilities providing our
facilities with electricity. See Managements Discussion and Analysis of Financial Condition and Results of OperationsFactors Which May Influence Future Results of OperationsClimate change legislation. We do not know if
or how the requirements will change, but changes may require that we make significant unanticipated expenditures, and such expenditures may materially adversely impact our financial condition, cash flow, results, cash available for distributions,
common stocks per share trading price, our competitive position and ability to satisfy our debt service obligations.

Insurance

We carry comprehensive liability, fire, extended coverage, earthquake, business interruption and rental loss insurance
covering all of the properties in our portfolio under a blanket policy. We select policy specifications and insured limits which we believe to be appropriate given the relative risk of loss, the cost of the coverage and industry practice and, in the
opinion of our companys management, the properties in our portfolio are currently adequately insured. We do not carry insurance for generally uninsured losses such as loss from war or nuclear reaction. In addition, we carry earthquake
insurance on our properties in an amount and with deductibles which we believe are commercially reasonable. Certain of the properties in our portfolio are located in areas known to be seismically active. See Risk FactorsRisks Related to
Our Business and OperationsPotential losses may not be covered by insurance.

Employees

As of December 31, 2013, we had 784 employees. None of these employees are represented by a labor union.

Risks
Related to Our Business and Operations

Global economic conditions could adversely affect our liquidity and
financial condition.

In the United States and globally, market and economic conditions have been unprecedented over the
past several years and challenging with tighter credit conditions and slower economic growth in many markets in which we own properties and conduct our operations. The U.S. and global economies have experienced a recession and face continued
concerns about the systemic impact of adverse economic conditions, such as high energy costs, geopolitical issues, the availability and cost of credit, unstable global financial and mortgage markets, high corporate, consumer and governmental debt
levels, high unemployment and declining residential and commercial real estate markets.

As a result of these conditions,
general economic conditions and the cost and availability of capital have been and may again be adversely affected in some or all of the markets in which we own properties and conduct our operations. Renewed or increased turbulence in the U.S.,
European and other international financial markets and economies may adversely affect our ability, and the ability of our tenants, to replace or renew maturing liabilities on a timely basis, access the capital markets to meet liquidity and capital
expenditure requirements and may result in adverse effects on our, and our tenants, businesses, financial condition and results of operations.

In addition, our access to funds under our global revolving credit facility depend on the ability of the lenders that are parties to such facilities to meet their funding commitments to us. We cannot
assure you that long-term disruptions in the global economy and tighter credit conditions among, and potential failures or nationalizations of, third party financial institutions as a result of such disruptions will not have an adverse effect on our
lenders. If our lenders are not able to meet their funding commitments to us, our business, results of operation, cash flows and financial condition could be adversely affected.

If we do not have sufficient cash flow to continue operating our business and are unable to borrow additional funds, access our existing
lines of credit or raise equity or debt capital, we may need to find alternative ways to increase our liquidity. Such alternatives may include, without limitation, curtailing development activity, disposing of one or more of our properties possibly
on disadvantageous terms or entering into or renewing leases on less favorable terms than we otherwise would.

Our
properties depend upon the demand for technology-related real estate.

Our portfolio of properties consists primarily of
technology-related real estate and datacenter real estate in particular. A decrease in the demand for datacenter space, Internet gateway facilities or other technology-related real estate would have a greater adverse effect on our business and
financial condition than if we owned a portfolio with a more diversified tenant base or less specialized use. Our substantial development activities make us particularly susceptible to general economic slowdowns, including recessions, as well as
adverse developments in the corporate datacenter, Internet and data communications and broader technology industries. Any such slowdown or adverse development could lead to reduced corporate IT spending or reduced demand for datacenter space.
Reduced demand could also result from business relocations, including to markets that we do

##### Table of Contents

not currently serve. Changes in industry practice or in technology, such as virtualization technology, more efficient or miniaturization of computing or networking devices, or devices that
require higher power densities than todays devices, could also reduce demand for the physical datacenter space we provide or make the tenant improvements in our facilities obsolete or in need of significant upgrades to remain viable. In
addition, the development of new technologies, the adoption of new industry standards or other factors could render many of our tenants current products and services obsolete or unmarketable and contribute to a downturn in their businesses,
thereby increasing the likelihood that they default under their leases, become insolvent or file for bankruptcy.

We may be
unable to lease vacant or development space or renew leases, or re-lease space as leases expire.

At
December 31, 2013, we owned approximately 1.8 million square feet of space under active development and approximately 1.3 million square feet of space held for future development. We intend to continue to add new space to our development
inventory and to continue to develop additional space from this inventory. A substantial portion of the space that we develop has been, and may continue to be, developed on a speculative basis, meaning that we do not have a signed lease for the
space when we begin the development process. We also develop space specifically for tenants pursuant to leases signed prior to beginning the development process. In those cases, if we fail to meet our development obligations under those leases,
these tenants may be able to terminate the leases and we would be required to find a new tenant for this space. In addition, in certain circumstances we lease data center facilities prior to their completion. If we fail to complete the facilities in
a timely manner, the tenant may be entitled to terminate its lease, seek damages or penalties against us or pursue other remedies and we may be required to find a new tenant for the space. We cannot assure you that once we have developed space or
land we will be able to successfully lease it at all, or at rates we consider favorable or expected at the time we commenced development. If we are not able to successfully lease the space that we develop, if development costs are higher than we
currently estimate, or if lease rates are lower than expected when we began the project or are otherwise undesirable, our revenue and operating results could be adversely affected.

In addition, as of December 31, 2013, leases representing 14.3% of the square footage of the properties in our portfolio, excluding
space held for development, were scheduled to expire through 2015, and an additional 7.8% of the net rentable square footage, excluding space held for development, was available to be leased. Some of this space may require substantial capital
investment to meet the power and cooling requirements of todays advanced data centers, or may no longer be suitable for this use. In addition, we cannot assure you that leases will be renewed or that our properties will be re-leased at all, or
at net effective rental rates equal to or above the current average net effective rental rates. If the rental rates for our properties decrease, our existing tenants do not renew their leases, we do not re-lease our available space, including newly
developed space and space for which leases are scheduled to expire, or it takes longer for us to lease or re-lease this space or for rents to commence on this space, our financial condition, results of operations, cash flow, cash available for
distribution and ability to satisfy our debt service obligations could be materially adversely affected.

Additionally,
leasing space in one of our data centers typically involves a significant commitment of resources and due diligence on the part of our customers regarding the adequacy of our facilities. As a result, the leasing of data center space can have a long
sales cycle, and we may expend significant time and resources in pursuing a particular transaction that may not result in revenue. Our inability to adequately manage the risks associated with the sales cycle may adversely affect our business,
financial condition and results of operations.

Our growth depends on external sources of capital which are outside of our
control.

In order for Digital Realty Trust, Inc. to maintain its qualification as a REIT, it is required under the
Internal Revenue Code of 1986, as amended, which we refer to as the Code, to annually distribute at least 90% of its net taxable income, determined without regard to the dividends paid deduction and excluding any net capital gain. In



9

##### Table of Contents

addition, Digital Realty Trust, Inc. will be subject to income tax at regular corporate rates to the extent that it distributes less than 100% of its net taxable income, including any net capital
gains. Digital Realty Trust, L.P. is required to make distributions to Digital Realty Trust, Inc. that will enable the latter to satisfy this distribution requirement and avoid income and excise tax liability. Because of these distribution
requirements, we may not be able to fund future capital needs, including any necessary acquisition or development financing, from operating cash flow. Consequently, we rely on third-party sources to fund our capital needs.

Our access to third-party sources of capital depends on a number of factors, including general market conditions, the markets
perception of our business prospects and growth potential, our current and expected future earnings, funds from operations and growth thereof, our cash flow and cash distributions, and the market price per share of Digital Realty Trust, Inc.s
common stock. We cannot assure you that we will be able to obtain equity or debt financing at all or on terms favorable or acceptable to us. Any additional debt we incur will increase our leverage. Further, equity markets have experienced high
volatility recently and we cannot assure you that we will be able to raise capital through the sale of equity securities at all or on favorable terms. Sales of equity on unfavorable terms could result in substantial dilution to Digital Realty Trust,
Inc.s common stockholders and Digital Realty Trust, L.P.s unitholders. In addition, we may be forced to dispose of one or more of our properties, possibly on disadvantageous terms.

If we cannot obtain capital from third-party sources, we may not be able to acquire or develop properties when strategic opportunities
exist, satisfy our debt service obligations, pay cash dividends to Digital Realty Trust, Inc.s stockholders or make distributions to Digital Realty Trust, L.P.s unitholders.

Declining real estate valuations and impairment charges could adversely affect our earnings and financial condition.

We review each of our properties for indicators that its carrying amount may not be recoverable. Examples of such indicators may include a
significant decrease in the market price, a significant adverse change in the extent or manner the property is being used in its physical condition or expected to be used based on the underwriting at the time of acquisition, an accumulation of costs
significantly in excess of the amount originally expected for the acquisition or development, or a history of operating or cash flow losses. When such impairment indicators exist, we review an estimate of the future undiscounted net cash flows
(excluding interest charges) expected to result from the real estate investments use and eventual disposition and compare to the carrying value of the property. We consider factors such as future operating income, trends and prospects, as well
as the effects of leasing demand, competition and other factors. If our future undiscounted net cash flow evaluation indicates that we are unable to recover the carrying value of a real estate investment, an impairment loss is recorded to the extent
that the carrying value exceeds the estimated fair value of the property. These losses have a direct impact on our net income because recording an impairment loss results in an immediate negative adjustment to net income. The evaluation of
anticipated cash flows is highly subjective and is based in part on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results in future periods. A worsening real estate market may
cause us to reevaluate the assumptions used in our impairment analysis. Impairment charges could adversely affect our financial condition, results of operations and cash available for distribution.

We depend on significant tenants, and many of our properties are single-tenant properties or are currently occupied by single tenants.

As of December 31, 2013, the 20 largest tenants in our property portfolio represented approximately 46% of the total
annualized rent generated by our properties. Our largest tenants by annualized rent are subsidiaries of CenturyLink, Inc. (Savvis/Qwest), IBM and telx Group, Inc. In 2011, CenturyLink, Inc. acquired Savvis Communications Corporation, or Savvis, and
Qwest Communications International, Inc., or Qwest, which are our direct tenants. Savvis and Qwest are now wholly-owned subsidiaries of CenturyLink, Inc. CenturyLink, Inc. (Savvis/Qwest) leased approximately 2.4 million square feet of net
rentable space as of December 31, 2013,

##### Table of Contents

representing approximately 7.8% of the total annualized rent generated by our properties. In July 2013, IBM acquired SoftLayer Technologies, Inc., which as of June 20, 2013, represented
approximately 4.0% of the total annualized rent generated by our properties. Including space leased by SoftLayer, IBM leased approximately 449,000 square feet of net rentable space as of December 31, 2013, representing approximately 5.5% of the
total annualized rent generated by our properties. telx Group, Inc. leased approximately 341,000 square feet of net rentable space as of December 31, 2013, representing approximately 4.3% of the total annualized rent generated by our
properties. In addition, 48 of our 131 properties are occupied by single tenants, including properties occupied solely by CenturyLink, Inc. (Savvis/Qwest) and IBM. Many factors, including global economic conditions, may cause our tenants to
experience a downturn in their businesses or otherwise experience a lack of liquidity, which may weaken their financial condition and result in their failure to make timely rental payments or their default under their leases. If any tenant defaults
or fails to make timely rent payments, we may experience delays in enforcing our rights as landlord and may incur substantial costs in protecting our investment.

Our tenants may choose to develop new data centers or expand their own existing data centers, which could result in the loss of one or more key tenants or reduce demand for our newly developed data
centers, which could have a material adverse effect on our revenues and results of operations.

Our tenants may choose to
develop new data centers or expand or consolidate into data centers that we do not own in the future. In the event that any of our key tenants were to do so, it could result in a loss of business to us or put pressure on our pricing. If we lose a
tenant, we cannot assure you that we would be able to replace that tenant at a competitive rate or at all, which could have a material adverse effect on our revenues and results of operations.

The bankruptcy or insolvency of a major tenant may adversely affect the income produced by our properties.

If any tenant becomes a debtor in a case under the federal Bankruptcy Code, we cannot evict the tenant solely because of the bankruptcy.
In addition, the bankruptcy court might authorize the tenant to reject and terminate its lease with us. Our claim against the tenant for unpaid, future rent would be subject to a statutory cap that might be substantially less than the remaining rent
actually owed under the lease. In either case, our claim for unpaid rent would likely not be paid in full. As of December 31, 2013, we had no material tenants in bankruptcy.

Our revenue and cash available for distribution could be materially adversely affected if any of our significant tenants were to become
bankrupt or insolvent, or suffer a downturn in its business, or fail to renew its lease or renew on terms less favorable to us than its current terms.

Our portfolio of properties depends upon local economic conditions and is geographically concentrated in certain locations.

Our portfolio is located in 33 metropolitan areas. Many of these markets experienced downturns in recent years and are currently experiencing downturns as a result of the global economic crisis or other
factors. We depend upon the local economic conditions in these markets, including local real estate conditions, and our operations, revenue and cash available for distribution could be materially adversely affected by local economic conditions in
these markets. Our operations may also be affected if too many competing properties are built in any of these markets or supply otherwise increases or exceeds demand. We cannot assure you that these markets will grow or will remain favorable to
technology-related real estate.

In addition, we are currently developing properties in certain of these markets. Any negative changes in real estate, technology or
economic conditions in these markets in particular could negatively impact our performance.

Our growth depends upon the
successful development of our existing space and developable land and new properties acquired for development and any delays or unexpected costs in such development may delay and harm our growth prospects, future operating results and financial
condition.

At December 31, 2013, we had approximately 1.8 million square feet of space under active development and
approximately 1.3 million square feet of space held for future development, including one vacant property. We have built and may continue to build out a large portion of this space on a speculative basis at significant cost. Our successful
development of these projects is subject to many risks, including those associated with:



| |  |  | delays in construction;
| | - |  | -----------------------



| |  |  | budget overruns;
| | - |  | ----------------



| |  |  | changes to the plans or specifications;
| | - |  | ---------------------------------------



| |  |  | construction site accidents and other casualties;
| | - |  | -------------------------------------------------



| |  |  | increased prices for raw materials or building supplies;
| | - |  | --------------------------------------------------------



| |  |  | lack of availability and/or increased costs for specialized data center components, including long lead time items such as generators;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------



| |  |  | financing availability, including our ability to obtain construction financing and permanent financing;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | increases in interest rates or credit spreads;
| | - |  | ----------------------------------------------



| |  |  | labor availability and costs;
| | - |  | -----------------------------

| |  |  | labor disputes and work stoppages with contractors, subcontractors or others that are constructing the project;
| | - |  | ---------------------------------------------------------------------------------------------------------------

| |  |  | delays or denials of entitlements or permits, including zoning and related permits, or other delays resulting from our dependence on the cooperation of
public agencies and utility companies.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, while we intend to develop data center properties
primarily in markets we are familiar with, we may in the future develop properties in new geographic regions where we expect the development of property to result in favorable risk-adjusted returns on our investment. We may not possess the same
level of familiarity with the development of other property types or other markets, which could adversely affect our ability to develop such properties successfully or at all or to achieve expected performance.

Development activities, regardless of whether they are ultimately successful, also typically require a substantial portion of our
managements time and attention. This may distract our management from focusing on other operational activities of our business. If we are unable to complete development projects successfully, our business may be adversely affected.

We may be unable to identify and complete acquisitions on favorable terms or at all.

We continually evaluate the market of available properties and businesses and may acquire additional technology-related real estate when
opportunities exist. Our ability to acquire properties or businesses on favorable terms may be exposed to the following significant risks:



| |  |  | we may be unable to acquire a desired property or business because of competition from other real estate investors with significant capital, including
both publicly traded REITs and institutional investment funds;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | even if we are able to acquire a desired property or business, competition from other potential acquirors may significantly increase the purchase price
or result in other less favorable terms;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | even if we enter into agreements for the acquisition of technology-related real estate or businesses, these agreements are subject to customary
conditions to closing, including completion of due diligence investigations to our satisfaction; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we may be unable to finance acquisitions on favorable terms or at all.
| | - |  | ----------------------------------------------------------------------

Additionally, we may acquire properties or businesses subject to liabilities and without any recourse, or with only limited recourse,
with respect to unknown or contingent liabilities, such as liabilities for clean-up of undisclosed environmental contamination, claims by tenants, vendors or other persons dealing with the former owners of the properties or businesses, tax
liabilities, claims for indemnification by general partners, directors, officers and others indemnified by the former owners of the properties or businesses, and other liabilities whether incurred in the ordinary course of business or otherwise. The
total amount of costs and expenses that we may incur with respect to liabilities associated with acquired properties or businesses may exceed our expectations, which may adversely affect our business, financial condition and results of operations.

##### Table of Contents

Further, we may enter into transactions with limited representations and warranties or with
representations and warranties that do not survive the closing of the transactions, in which event we would have no or limited recourse against the sellers of such properties or businesses. While we usually require the sellers to indemnify us with
respect to breaches of representations and warranties that survive, such indemnification is often limited and subject to various materiality thresholds, a significant deductible or an aggregate cap on losses. As a result, there is no guarantee that
we will recover any amounts with respect to losses due to breaches by the sellers of their representations and warranties. Finally, indemnification agreements between us and the sellers typically provide that the sellers will retain certain
specified liabilities relating to the properties or businesses acquired by us. While the sellers are generally contractually obligated to pay all losses and other expenses relating to such retained liabilities, there can be no guarantee that such
arrangements will not require us to incur losses or other expenses as well.

If we cannot complete property or business
acquisitions on favorable terms or at all, our financial condition, results of operations, cash flow, cash available for distribution and ability to satisfy our debt service obligations could be materially adversely affected.

We may be unable to successfully integrate and operate acquired properties or businesses.

Even if we are able to make acquisitions on advantageous terms, our ability to successfully operate them may be exposed to the following
significant risks:



| |  |  | we may spend more than budgeted amounts to make necessary improvements or renovations to acquired properties;
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | we may be unable to integrate new acquisitions quickly and efficiently, particularly acquisitions of operating businesses or portfolios of properties,
into our existing operations, and our results of operations and financial condition could be adversely affected;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | acquired properties may be subject to reassessment, which may result in higher than expected property tax payments; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------



| |  |  | market conditions may result in higher than expected vacancy rates and lower than expected rental rates.
| | - |  | --------------------------------------------------------------------------------------------------------

If we cannot operate acquired properties or businesses to meet our financial expectations, our financial condition, results of
operations, cash flow, cash available for distribution and ability to satisfy our debt service obligations could be materially adversely affected.

We may be unable to source off-market deal flow in the future.

A component
of our growth strategy is to continue to acquire additional technology-related real estate. To date, a substantial portion of our acquisitions were acquired before they were widely marketed by real estate brokers, or off-market.
Properties that are acquired off-market are typically more attractive to us as a purchaser because of the absence of competitive bidding, which could potentially lead to higher prices. We obtain access to off-market deal flow from numerous sources.
If we cannot obtain off-market deal flow in the future, our ability to locate and acquire additional properties at attractive prices could be adversely affected.

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 total consolidated indebtedness at December 31, 2013 was approximately $5.0 billion, and we may incur significant additional debt
to finance future acquisition and development activities. We have a $2.0 billion global revolving credit facility, which has a borrowing limit that we may increase to up to $2.55 billion, subject to receipt of lender commitments and other conditions
precedent. At December 31, 2013, approximately $1.3 billion was available under this facility, net of outstanding letters of credit.

##### Table of Contents

Our substantial indebtedness has important consequences in that it currently requires us to
dedicate a significant portion of our cash flow from operations to debt service payments, which reduces the availability of our cash flow to fund working capital, capital expenditures, expansion efforts, distributions and other general corporate
purposes. Additionally, it could: make it more difficult for us to satisfy our obligations with respect to our indebtedness; limit our ability in the future to undertake refinancings of our debt or obtain financing for expenditures, acquisitions,
development or other general corporate purposes on terms and conditions acceptable to us, if at all; or affect adversely our ability to compete effectively or operate successfully under adverse economic conditions.

In addition, we may violate restrictive covenants or fail to maintain financial ratios specified in our loan documents, which would
entitle the lenders to accelerate our debt obligations, and our secured lenders or mortgagees may foreclose on our properties or our interests in the entities that own the properties that secure their loans and receive an assignment of rents and
leases. A foreclosure on one or more of our properties could adversely affect our access to capital, financial condition, results of operations, cash flow and cash available for distribution. Further, our default under any one of our loans could
result in a cross default on other indebtedness. Furthermore, foreclosures could create taxable income without accompanying cash proceeds, a circumstance which could hinder Digital Realty Trust, Inc.s ability to meet the REIT distribution
requirements imposed by the Code.

Additional risks related to our indebtedness are described below.

We may be unable to refinance our indebtedness at maturity or the refinancing terms may be less favorable than the terms of our
original indebtedness.It is likely that we will need to refinance at least a portion of our outstanding debt as it matures. If we are unable to refinance or extend principal payments due at maturity or pay them with proceeds of other capital
transactions, then our cash flow may not be sufficient in all years to repay all such maturing debt and to pay distributions. Further, if prevailing interest rates or other factors at the time of refinancing (such as the reluctance of lenders to
make commercial real estate loans) result in higher interest rates upon refinancing, then the interest expense relating to that refinanced indebtedness would increase.

Fluctuations in interest rates could materially affect our financial results and may increase the risk our counterparty defaults on our interest rate hedges. Because a significant portion of our
debt, including debt incurred under our global revolving credit facility, bears interest at variable rates, increases in interest rates could materially increase our interest expense. If the United States Federal Reserve increases short-term
interest rates, this would have a significant upward impact on shorter-term interest rates, including the interest rates that our variable rate debt is based upon. Potential future increases in interest rates and credit spreads may increase our
interest expense and therefore negatively affect our financial condition and results of operations, and reduce our access to capital markets. We have entered into interest rate swap agreements for a significant portion of our floating rate debt
other than the debt we incur under our global revolving credit facility. Increased interest rates may increase the risk that the counterparties to our swap agreements will default on their obligations, which could further increase our exposure to
interest rate fluctuations. Conversely, if interest rates are lower than our swapped fixed rates, we will be required to pay more for our debt than we would had we not entered into the swap agreements.

Adverse changes in our companys credit ratings could negatively affect our financing activity. The credit ratings of our
senior unsecured long-term debt and Digital Realty Trust, Inc.s preferred stock are based on our companys operating performance, liquidity and leverage ratios, overall financial position and other factors employed by the credit rating
agencies in their rating analyses of our company. Our companys credit ratings can affect the amount of capital we can access, as well as the terms and pricing of any debt we may incur. We cannot assure you that our company will be able to
maintain our current credit ratings, and in the event our current credit ratings are downgraded, we would likely incur higher borrowing costs and may encounter difficulty in obtaining additional financing. Also, a downgrade in our companys
credit ratings may trigger additional payments or other negative consequences under our current and future credit facilities and debt instruments. For example, if the credit ratings of our senior unsecured long-term debt are downgraded to below
investment grade levels, we may

not be able to obtain or maintain extensions on certain of our existing debt. Adverse changes in our credit ratings could negatively impact our refinancing and other capital market activities,
our ability to manage our debt maturities, our future growth, our financial condition, the market price of Digital Realty Trust, Inc.s stock, and our development and acquisition activity.

Our global revolving credit facility, term loan facility,Prudential shelf facility, 5.875% notes due 2020, 4.50% notes due
2015, 5.250% notes due 2021, 3.625% notes due 2022 and 4.250% guaranteed notes due 2025 restrict our ability to engage in some business activities. Our global revolving credit facility, term loan facility and Prudential shelf facility contain
negative covenants and other financial and operating covenants that, among other things:



| |  |  | restrict our ability to incur additional indebtedness;
| | - |  | ------------------------------------------------------



| |  |  | restrict our ability to make certain investments;
| | - |  | -------------------------------------------------



| |  |  | restrict our ability to merge with another company;
| | - |  | ---------------------------------------------------



| |  |  | restrict our ability to create, incur or assume liens; and
| | - |  | ----------------------------------------------------------



| |  |  | require us to maintain financial coverage ratios, including with respect to unencumbered assets.
| | - |  | ------------------------------------------------------------------------------------------------

In addition, the global revolving credit facility, the term loan facility and the Prudential shelf facility restrict Digital Realty
Trust, Inc. from making distributions to its stockholders, or redeeming or otherwise repurchasing shares of its capital stock, after the occurrence and during the continuance of an event of default, except in limited circumstances including as
necessary to enable Digital Realty Trust, Inc. to maintain its qualification as a REIT and to avoid the payment of income or excise tax.

In addition, our 5.875% notes due 2020, or the 2020 notes, our 4.50% notes due 2015, or the 2015 notes, our 5.250% notes due 2021, or the 2021 notes, our 3.625% notes due 2022, or the 2022 notes, and the
2025 notes are governed by indentures, which contain various restrictive covenants, including limitations on our ability to incur indebtedness and requirements to maintain a pool of unencumbered assets. These restrictions, and the restrictions in
our global revolving credit facility, term loan facility, and Prudential shelf facility, could cause us to default on our 2020 notes, 2015 notes, 2021 notes, 2022 notes, 2025 notes, global revolving credit facility, term loan facility or Prudential
shelf facility, as applicable, or negatively affect our operations or our ability to pay dividends to Digital Realty Trust, Inc.s stockholders or distributions to Digital Realty Trust, L.P.s unitholders, which could have a material
adverse effect on the market value of Digital Realty Trust, Inc.s common stock and preferred stock.

The exchange and
repurchase rights of our exchangeable debentures may be detrimental to Digital Realty Trust, Inc.s stockholders or Digital Realty Trust, L.P.s unitholders. As of December 31, 2013, Digital Realty Trust, L.P. had outstanding
$266.4 million aggregate principal amount of 5.50% Exchangeable Senior Debentures due 2029, or the 2029 debentures. The 2029 debentures are exchangeable for Digital Realty Trust, Inc.s common stock. The exchange rate of the 2029 debentures is
subject to adjustment for certain events, including, but not limited to, certain dividends on Digital Realty Trust, Inc.s common stock in excess of $0.33 per share per quarter, the issuance of certain rights, options or warrants to holders of
Digital Realty Trust, Inc.s common stock, subdivisions or combinations of Digital Realty Trust, Inc.s common stock, certain distributions of assets, debt securities, capital stock or cash to holders of Digital Realty Trust, Inc.s
common stock and certain tender or exchange offers. The 2029 debentures are redeemable at our option for cash at any time on or after April 18, 2014 and are subject to repurchase for cash at the option of the holder on April 15 in the
years 2014, 2019 and 2024, or upon the occurrence of certain events.

If the 2029 debentures are not exchanged, the repurchase
rights of holders of the exchangeable debentures may discourage or impede transactions that might otherwise be in the interest of Digital Realty Trust, Inc.s stockholders or Digital Realty Trust, L.P.s unitholders. Further, these
exchange or repurchase rights might be triggered in situations where we need to conserve our cash reserves, in which event such repurchase might adversely affect us, Digital Realty Trust, Inc.s stockholders and Digital Realty
Trust, L.P.s unitholders.

Failure to hedge effectively against interest rate changes may adversely affect results
of operations. We seek to manage our exposure to interest rate volatility by using interest rate hedging arrangements, such as interest rate cap or swap lock agreements. These agreements involve risks, such as the risk that counterparties may
fail to honor their obligations under these arrangements, that these arrangements may not be effective in reducing our exposure to interest rate changes and that a court could rule that such an agreement is not legally enforceable. Our policy is to
use derivatives only to hedge interest rate risks related to our borrowings, not for speculative or trading purposes, and to enter into contracts only with major financial institutions based on their credit ratings and other factors. However, we may
choose to change this policy in the future. Approximately 76% of our total indebtedness as of December 31, 2013 was subject to fixed interest rates or variable rates subject to interest rate swaps. We do not currently hedge our global revolving
credit facility and as our borrowings under our global revolving credit facility increase, so will our percentage of indebtedness not subject to fixed rates and our exposure to interest rates increase. Hedging may reduce the overall returns on our
investments. Failure to hedge effectively against interest rate changes may materially adversely affect our results of operations.

Volatility in and regulation of the commercial mortgage-backed securities market has limited and may continue to impact the pricing of secured debt.As a result of the recent crisis in the
residential mortgage-backed securities markets, the recent global recession, and concerns over the ability to refinance or repay existing commercial mortgage-backed securities as they come due, liquidity previously provided by the commercial
mortgage-backed securities and collateralized debt obligations markets has significantly decreased. In addition, the Dodd-Frank Wall Street Reform and Consumer Protection Act imposes significant new regulations related to the mortgage-backed
securities industry and market participants, which has contributed to uncertainty in the market. The volatility in the commercial mortgage-backed securities market could result in the following adverse effects on our incurrence of secured debt,
which could have a materially negative impact on our financial condition, results of operations, cash flow and cash available for distribution:



| |  |  | higher loan spreads;
| | - |  | --------------------



| |  |  | tighter loan covenants;
| | - |  | -----------------------



| |  |  | reduced loan to value ratios and resulting borrower proceeds; and
| | - |  | -----------------------------------------------------------------



| |  |  | higher amortization and reserve requirements.
| | - |  | ---------------------------------------------

We have owned certain of our properties for a limited time.

We owned 131 properties at December 31, 2013, including 12 properties held as investments in unconsolidated joint ventures and developable land. All of our properties have been under our management
for less than ten years, and we have owned seven of the properties for less than one year at December 31, 2013. The properties may have characteristics or deficiencies unknown to us that could affect their valuation or revenue potential. We
cannot assure you that the operating performance of the properties will not decline under our management.

We may have
difficulty managing our growth.

We have significantly and rapidly expanded the size of our company. For example, during
2013, we acquired seven properties and we increased the number and size of our development activities. Our growth may significantly strain our management, operational and financial resources and systems. In addition, as a reporting company, we are
subject to the reporting requirements of the Exchange Act and the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act. The requirements of these rules and regulations will increase our accounting, legal and financial compliance costs and may
strain our management and financial, legal and operational resources and systems. An inability to manage our growth effectively or the increased strain on our management of our resources and systems could result in deficiencies in our disclosure
controls and procedures or our internal control over financial reporting and could negatively impact our cash available for distribution.

Potential losses may not be covered by insurance.

We currently carry comprehensive liability, property, business interruption, including loss of rental income, and other insurance policies
to cover insurable risks to our company. We select policy specifications, insured limits and deductibles which we believe to be appropriate and adequate given the relative risk of loss, the cost of the coverage and standard industry practices. Our
insurance policies contain industry standard exclusions and we do not carry insurance for generally uninsurable perils such as loss from war or nuclear reaction. Although we purchase earthquake insurance,it is subject to high deductibles and
a significant portion of our properties is located in seismically active zones such as California, which represents approximately 20% of our portfolios annualized rent as of December 31, 2013. One catastrophic event, for example, in
California, could significantly impact multiple properties, the aggregate deductible amounts could be significant and the limits we purchase could prove to be insufficient, which could materially and adversely impact our business, financial
condition and results of operations. Furthermore, a catastrophic regional event could also severely impact some of our insurers rendering them insolvent or unable to fully pay on claims despite their current financial strength. In addition, we may
discontinue purchasing insurance against earthquake, flood or windstorm or other perils on some or all of our properties in the future if the cost of premiums for any of these policies exceeds, in our judgment, the value of the coverage relative to
the risk of loss.

In addition, many of our buildings contain extensive and highly valuable technology-related improvements.
Under the terms of our leases, tenants are obligated to maintain adequate insurance coverage applicable to such improvements and under most circumstances use their insurance proceeds to restore such improvements after a casualty event. In the event
of a casualty or other loss involving one of our buildings with extensive installed tenant improvements, our tenants may have the right to terminate their leases if we do not rebuild the base building within prescribed times. In such cases, the
proceeds from tenants insurance will not be available to us to restore the improvements, and our insurance coverage may be insufficient to replicate the technology-related improvements made by such tenants. Furthermore, the terms of our
mortgage indebtedness at certain of our properties may require us to pay insurance proceeds over to our lenders under certain circumstances, rather than use the proceeds to repair the property. If we or one or more of our tenants experiences a loss
which is uninsured or which exceeds policy limits, we could lose the capital invested in the damaged properties as well as the anticipated future cash flows from those properties. In addition, if the damaged properties are subject to recourse
indebtedness, we would continue to be liable for the indebtedness, even if these properties were irreparably damaged.

We
face significant competition, which may decrease or prevent increases of the occupancy and rental rates of our properties.

We compete with numerous developers, owners and operators of real estate and datacenters, many of which own properties similar to ours in
the same markets in which our properties are located, including DuPont Fabros Technology, Inc., CoreSite Realty Corporation, CyrusOne Inc., QTS Realty Trust, Inc. and various local developers in the U.S., as well as Global Switch Holdings Limited
and various regional operators in Europe, Asia and Australia. In addition, we may in the future face competition from new entrants into the datacenter market, including new entrants who may acquire our current competitors. Some of our competitors
and potential competitors have significant advantages over us, including greater name recognition, longer operating histories, pre-existing relationships with current or potential customers, significantly greater financial, marketing and other
resources and more ready access to capital which allow them to respond more quickly to new or changing opportunities. If our competitors offer space that our tenants or potential tenants perceive to be superior to ours based on numerous factors,
including available power, security considerations, location, or connectivity, or if they offer rental rates below current market rates, or below the rental rates we are offering, we may lose tenants or potential tenants or be required to incur
costs to improve our properties or reduce our rental rates. In addition, recently many of our competitors have developed and continue to develop additional datacenter space. If the supply of datacenter space continues to increase as a result of
these activities or otherwise, rental rates may be reduced or we may face delays in leasing or be unable to lease our vacant space, including space that we develop.

Further, if tenants or potential tenants desire services that we do not offer, we may not be
able to lease our space to those tenants. Our financial condition, results of operations, cash flow, cash available for distribution and ability to satisfy our debt service obligations could be materially adversely affected as a result of any or all
of these factors.

Joint venture investments could be adversely affected by our lack of sole decision-making authority, our
reliance on co-venturers financial condition and disputes between us and our co-venturers.

We currently, and may in
the future, co-invest with third parties through partnerships, joint ventures or other entities, acquiring non-controlling interests in or sharing responsibility for managing the affairs of a property, partnership, joint venture or other entity. In
these events, we are not in a position to exercise sole decision-making authority regarding the property, partnership, joint venture or other entity. Investments in partnerships, joint ventures, or other entities may, under certain circumstances,
involve risks not present when a third party is not involved, including the possibility that partners or co-venturers might become bankrupt or fail to fund their share of required capital contributions. Partners or co-venturers may have economic,
tax or other business interests or goals which are inconsistent with our business interests or goals, and may be in a position to take actions contrary to our policies or objectives. Our joint venture partners may take actions that are not within
our control, which would require us to dispose of the joint venture asset or transfer it to a taxable REIT subsidiary in order for Digital Realty Trust, Inc. to maintain its status as a REIT. Such investments may also lead to impasses, for example,
as to whether to sell a property, because neither we nor the partner or co-venturer would have full control over the partnership or joint venture. Disputes between us and partners or co-venturers may result in litigation or arbitration that would
increase our expenses and prevent our officers and/or directors from focusing their time and effort on our day-to-day business. Consequently, actions by or disputes with partners or co-venturers may subject properties owned by the partnership or
joint venture to additional risk. In addition, we may in certain circumstances be liable for the actions of our third-party partners or co-venturers. Each of these factors may result in returns on these investments being less than we expect or in
losses and our financial and operating results may be adversely affected.

Our success depends on key personnel whose
continued service is not guaranteed.

We depend on the efforts of key personnel of our company, particularly Michael Foust,
Digital Realty Trust, Inc.s Chief Executive Officer, A. William Stein, Digital Realty Trust, Inc.s Chief Financial Officer and Chief Investment Officer and Scott Peterson, Digital Realty Trust, Inc.s Chief Acquisitions
Officer. They are important to our success for many reasons, including that each has a national or regional reputation in our industry and the investment community that attracts investors and business and investment opportunities and assists us in
negotiations with investors, lenders, existing and potential tenants and industry personnel. If we lost their services, our business and investment opportunities and our relationships with lenders and other capital markets participants, existing and
prospective tenants and industry personnel could suffer. Many of our companys other senior employees also have strong technology, finance and real estate industry reputations. As a result, we have greater access to potential acquisitions,
financing, leasing and other opportunities, and are better able to negotiate with tenants. As the number of our competitors increases, it becomes more likely that a competitor would attempt to hire certain of these individuals away from our company.
The loss of any of these key personnel would result in the loss of these and other benefits and could materially and adversely affect our results of operations.

Our properties may not be suitable for lease to datacenter or traditional technology office tenants without significant expenditures or renovations.

Because many of our properties contain tenant improvements installed at our tenants expense, they may be better suited for a
specific corporate enterprise datacenter user or technology industry tenant and could require significant modification in order for us to re-lease vacant space to another corporate enterprise datacenter user or technology industry tenant. The tenant
improvements may also become outdated or obsolete as the result of



19

##### Table of Contents

technological change, the passage of time or other factors. In addition, our development space will generally require substantial improvement to be suitable for datacenter use. For the same
reason, our properties also may not be suitable for lease to traditional office tenants without significant expenditures or renovations. As a result, we may be required to invest significant amounts or offer significant discounts to tenants in order
to lease or re-lease that space, either of which could adversely affect our financial and operating results.

Our data
center infrastructure may become obsolete, and we may not be able to upgrade our power and cooling systems cost-effectively, or at all.

Our data center infrastructure may become obsolete due to the development of new systems to deliver power to or eliminate heat in our facilities. Additionally, our data center infrastructure could become
obsolete as a result of the development of new server technology that does not require the levels of critical load and heat removal that our facilities are designed to provide and could be run less expensively on a different platform. In addition,
our power and cooling systems are difficult and expensive to upgrade. Accordingly, we may not be able to efficiently upgrade or change these systems to meet new demands without incurring significant costs that we may not be able to pass on to our
customers which could adversely impact our business, financial condition and results of operations.

Ownership of
properties located outside of the United States subjects us to foreign currency and related risks which may adversely impact our ability to make distributions.

We owned 29 properties located outside of the United States at December 31, 2013. In addition, we are currently considering, and will in the future consider, additional international acquisitions.

The ownership of properties located outside of the United States subjects us to risk from fluctuations in exchange rates
between foreign currencies and the U.S. dollar. We expect that our principal foreign currency exposure will be to the British Pound and the Euro. Changes in the relation of these currencies to the U.S. dollar will affect our revenues and operating
margins, may materially adversely impact our financial condition, results of operations, cash flow, cash available for distribution and ability to satisfy our debt obligations.

We may attempt to mitigate some or all of the risk of currency fluctuation by financing our properties in the local currency
denominations, although we cannot assure you that we will be able to do so or that this will be effective. We may also engage in direct hedging activities to mitigate the risks of exchange rate fluctuations in a manner consistent with our
qualifications as a REIT, although we cannot assure you that we will be able to do so or that this will be effective.

Our
international activities are subject to special risks different than those faced by us in the United States and we may not be able to effectively manage our international business.

We have acquired and developed, and may continue to acquire and develop, properties outside the United States. Our foreign operations
involve risks not generally associated with investments in the United States, including:



| |  |  | our limited knowledge of and relationships with sellers, tenants, contractors, suppliers or other parties in these markets;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | complexity and costs associated with managing international development and operations;
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | difficulty in hiring qualified management, sales and construction personnel and service providers in a timely fashion;
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | differing employment practices and labor issues;
| | - |  | ------------------------------------------------



| |  |  | multiple, conflicting and changing legal, regulatory, entitlement and permitting, and tax and treaty environments;
| | - |  | ------------------------------------------------------------------------------------------------------------------

| |  |  | exposure to increased taxation, confiscation or expropriation;
| | - |  | --------------------------------------------------------------



| |  |  | currency transfer restrictions and limitations on our ability to distribute cash earned in foreign jurisdictions to the United States;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------



| |  |  | difficulty in enforcing agreements in non-U.S. jurisdictions, including those entered into in connection with our acquisitions or in the event of a
default by one or more of our tenants, suppliers or contractors;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | local business and cultural factors; and
| | - |  | ----------------------------------------



| |  |  | political and economic instability, including sovereign credit risk, in certain geographic regions.
| | - |  | ---------------------------------------------------------------------------------------------------

Our inability to overcome these risks could adversely affect our foreign operations and could harm our business and results of
operations.

We face risks with our international acquisitions associated with investing in unfamiliar markets.

We have acquired and may continue to acquire properties on a strategic and selective basis in international markets that
are new to us. When we acquire properties located in these markets, we may face risks associated with a lack of market knowledge or understanding of the local economy and culture, forging new business relationships in the area and unfamiliarity with
local government and permitting procedures. In addition, due diligence, transaction and structuring costs may be higher than those we may face in the United States. We work to mitigate such risks through extensive diligence and research and
associations with experienced partners; however, we cannot assure you that all such risks will be eliminated.

Future
consolidation in the technology industry could materially adversely affect our revenues by eliminating some of our potential tenants and could make us more dependent on a more limited number of tenants.

Mergers or consolidations of technology companies in the future could reduce the number of our tenants and potential tenants. If our
tenants merge with or are acquired by other entities that are not our tenants, they may discontinue or reduce the use of our data centers in the future. Any of these developments could have a material adverse effect on our revenues and results of
operations.

We depend on third parties to provide Internet connectivity to the tenants in our data centers and any delays
or disruptions in connectivity may materially adversely affect our operating results and cash flow.

We are not a
telecommunications carrier. Although our tenants generally are responsible for providing their own network connectivity, we still depend upon the presence of telecommunications carriers fiber networks serving the locations of our data centers
in order to attract and retain tenants. We believe that the availability of carrier capacity will directly affect our ability to achieve our projected results. Any carrier may elect not to offer its services within our data centers. Any carrier that
has decided to provide Internet connectivity to our data centers may not continue to do so for any period of time. Further, some carriers are experiencing business difficulties or have announced consolidations. As a result, some carriers may be
forced to downsize or terminate connectivity within our data centers, which could have an adverse effect on the business of our tenants and, in turn, our own operating results.

Our new data centers require construction and operation of a sophisticated redundant fiber network. The construction required to connect
multiple carrier facilities to our data centers is complex and involves factors outside of our control, including regulatory requirements and the availability of construction resources. We have started to obtain the right to use network resources
owned by other companies, including rights to use dark fiber, in order to attract telecommunications carriers and customers to our portfolio. If the establishment of highly diverse Internet connectivity to our data centers does not occur, is
materially delayed or is discontinued, or is subject to failure, our operating results and cash flow may be materially adversely affected. Additionally, any hardware or fiber failures on this network may result in significant loss of connectivity to
our data centers. This

could negatively affect our ability to attract new tenants or retain existing tenants, which could have an adverse effect on our business, financial condition and results of operations.

Any failure of our physical infrastructure or services could lead to significant costs and disruptions that could harm our
business reputation and could adversely affect our earnings and financial condition.

Our business depends on providing
customers with highly reliable service, including with respect to power supply, security and maintenance of environmental conditions. We may fail to provide such service as a result of numerous factors, including mechanical failure, power outage,
human error, physical or electronic security breaches, war, terrorism and related conflicts or similar events worldwide, fire, earthquake, hurricane, flood and other natural disasters, sabotage and vandalism.

Problems at one or more of our data centers, whether or not within our control, could result in service interruptions or equipment
damage. Substantially all of our customer leases include terms requiring us to meet certain service level commitments to our customers. Any failure to meet these commitments or any equipment damage in our data centers, including as a result of
mechanical failure, power outage, human error or other reasons, could subject us to liability under our lease terms, including service level credits against customer rent payments, or, in certain cases of repeated failures, the right by the customer
to terminate the lease. Service interruptions, equipment failures or security breaches may also expose us to additional legal liability and damage our brand and reputation, and could cause our customers to terminate or not renew their leases. In
addition, we may be unable to attract new customers if we have a reputation for service disruptions, equipment failures or physical or electronic security breaches in our data centers. Any such failures could adversely affect our business, financial
condition and results of operations.

We are dependent upon third-party suppliers for power and certain other services, and
we are vulnerable to service failures of our third-party suppliers and to price increases by such suppliers.

We rely on
third parties to provide power to our data centers, and we cannot ensure that these third parties will deliver such power in adequate quantities or on a consistent basis. If the amount of power available to us is inadequate to support our customer
requirements, we may be unable to satisfy our obligations to our customers or grow our business. In addition, our data centers may be susceptible to power shortages and planned or unplanned power outages caused by these shortages. Power outages may
last beyond our backup and alternative power arrangements, which would harm our customers and our business. Any loss of services or equipment damage could adversely affect both our ability to generate revenues and our operating results, and harm our
reputation.

In addition, we may be subject to risks and unanticipated costs associated with obtaining power from various
utility companies. Utilities that serve our data centers may be dependent on, and sensitive to price increases for, a particular type of fuel, such as coal, oil or natural gas. In addition, the price of these fuels and the electricity generated from
them could increase as a result of proposed legislative measures related to climate change or efforts to regulate carbon emissions. Increases in the cost of power at any of our data centers would put those locations at a competitive disadvantage
relative to data centers served by utilities that can provide less expensive power.

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.

As current and future customers increase their power footprint in our facilities over time, the corresponding reduction in available power
could limit our ability to increase occupancy rates or network density within our existing facilities. Furthermore, at certain of our data centers, our aggregate maximum contractual obligation to provide power and cooling to our customers may exceed
the physical capacity at such data centers if customers were to quickly increase their demand for power and cooling. If we are not able to increase the available power and/or cooling or move the customer to another location within our data centers
with sufficient power and



22

##### Table of Contents

cooling to meet such demand, we could lose the customer as well as be exposed to liability under our leases. In addition, our power and cooling systems are difficult and expensive to upgrade.
Accordingly, we may not be able to efficiently upgrade or change these systems to meet new demands without incurring significant costs that we may not be able to pass on to our customers. Any such material loss of customers, liability or additional
costs could adversely affect our business, financial condition and results of operations.

We may be vulnerable to breaches
of our physical security, or to unauthorized access to or disruption of our customers networks or our information technology systems, any of which could disrupt our operations and have a material adverse effect on our revenues and results of
operations.

We use a variety of procedures and systems to maintain the physical security of our facilities. Any failure of
these systems, whether caused by human error, third party attack, employee malfeasance, system error, utility failure or some other cause could result in, among other things, a breach of our customers networks, a breach of our obligations
under our customer leases, the misappropriation of our or our customers or their customers proprietary information, or interruptions or malfunctions in our or our customers operations. We rely upon our information technology
systems to manage customer relationships, maintain access lists and to maintain our financial and other business information. Unauthorized access to or disruption of these systems could result in, among other things, unauthorized access to our
facilities, delays or interruptions to our ability to meet customer needs, breach of our legal or contractual obligations or inability to access or rely upon critical business records. We may be required to expend significant financial resources to
protect against or to alleviate breaches of physical security, network breaches as well as unauthorized access to or disruption of our customers networks or our information technology systems. We may not be able to implement physical or
technical security measures in a timely manner or, if and when implemented, these measures could be circumvented. Any breaches that may occur could expose us to increased risk of lawsuits, loss of existing or potential customers, harm to our
reputation and increases in our security costs, which could have a material adverse effect on our revenues and results of operations.

Illiquidity of real estate investments could significantly impede our ability to respond to adverse changes in the performance of our properties and harm our financial condition.

Because real estate investments are relatively illiquid and because there may be even fewer buyers for our specialized real estate, our
ability to promptly sell properties in our portfolio in response to adverse changes in their performance may be limited, which may harm our financial condition. Further, Digital Realty Trust, Inc. is subject to provisions in the Code that limit a
REITs ability to dispose of properties, which limitations are not applicable to other types of real estate companies. While Digital Realty Trust, Inc. has exclusive authority under Digital Realty Trust, L.P.s limited partnership
agreement to determine whether, when, and on what terms to sell a property, any such decision would require the approval of Digital Realty Trust, Inc.s board of directors. See Risks Related to Our Organizational StructureTax
consequences upon sale or refinancing. These limitations may affect our ability to sell properties. This lack of liquidity and the Code restrictions may limit our ability to vary our portfolio promptly in response to changes in economic or
other conditions and, as a result, could adversely affect our financial condition, results of operations, cash flow, cash available for distribution and ability to access capital necessary to meet our debt payments and other obligations.

We could incur significant costs related to government regulation and private litigation over environmental matters.

Under various laws relating to the protection of the environment, a current or previous owner or operator of real estate may be liable for
contamination resulting from the presence or discharge of hazardous or toxic substances at that property, and may be required to investigate and clean up such contamination at or emanating from that property. Such laws often impose liability without
regard to whether the owner or operator knew of, or was responsible for, the presence of the contaminants, and the liability may be joint and several. Previous owners used some of our properties for industrial and retail purposes, so those
properties may contain some level of environmental contamination. Fuel storage tanks are present at most of our properties, and if releases were to occur, we may be liable for the costs of cleaning any resulting contamination. The presence of
contamination or



23



---

##### Table of Contents

the failure to remediate contamination at our properties may expose us to third-party liability or materially adversely affect our ability to sell, lease or develop the real estate or to borrow
using the real estate as collateral.

Some of the properties may contain asbestos-containing building materials. Environmental
laws require that asbestos-containing building materials be properly managed and maintained, and may impose fines and penalties on building owners or operators for failure to comply with these requirements. These laws may also allow third parties to
seek recovery from owners or operators for personal injury associated with exposure to asbestos-containing building materials.

In addition, some of our tenants, particularly those in the biotechnology and life sciences industry and those in the technology
manufacturing industry, routinely handle hazardous substances and wastes as part of their operations at our properties. Environmental laws and regulations subject our tenants, and potentially us, to liability resulting from these activities or from
previous industrial or retail uses of those properties. Environmental liabilities could also affect a tenants ability to make rental payments to us.

Our properties and their uses often require permits from various government agencies, including permits related to zoning and land use, such as permits to operate data center facilities. Certain permits
from state or local environmental regulatory agencies, including regulators of air quality, are usually required to install and operate diesel-powered generators, which provide emergency back-up power at most of our facilities. These permits often
set emissions limits for certain air pollutants, including oxides of nitrogen. In addition, various federal, state, and local environmental, health and safety requirements, such as fire requirements and treated and storm water discharge
requirements, apply to some of our properties. Changes to applicable regulations, such as air quality regulations, or the permit requirements for equipment at our facilities, could hinder or prevent our construction or operation of data center
facilities.

The environmental laws and regulations to which our properties are subject may change in the future, and new laws
and regulations may be created. Such laws include those directly regulating our climate change impacts and those which regulate the climate change impacts of companies with which we do business, such as utilities providing our facilities with
electricity. See Managements Discussion and Analysis of Financial Condition and Results of OperationsFactors Which May Influence Future Results of OperationsClimate change legislation. We do not know if or how the
requirements will change, but changes may require that we make significant unanticipated expenditures, and such expenditures may materially adversely impact our financial condition, cash flow, results, cash available for distributions, common
stocks per share trading price, our competitive position and ability to satisfy our debt service obligations.

Existing conditions at some of our properties may expose us to liability related to environmental matters.

Independent environmental consultants have conducted Phase I or similar environmental site assessments on all of the properties in our
portfolio. Site assessments are intended to discover and evaluate information regarding the environmental condition of the surveyed property and surrounding properties. These assessments do not generally include soil samplings, subsurface
investigations or an asbestos survey and the assessments may fail to reveal all environmental conditions, liabilities or compliance concerns. In addition, material environmental conditions, liabilities or compliance concerns may have arisen after
these reviews were completed or may arise in the future. Future laws, ordinances or regulations may impose additional material environmental liability.

We cannot assure you that costs of future environmental compliance will not affect our ability to pay dividends to Digital Realty Trust, Inc.s stockholders and distributions to Digital Realty Trust,
L.P.s unitholders or that such costs or other remedial measures will not have a material adverse effect on our business, assets or results of operations.

Our properties may contain or develop harmful mold or suffer from other air quality
issues, which could lead to liability for adverse health effects and costs to remedy the problem.

When excessive moisture
accumulates in buildings or on building materials, mold may grow, particularly if the moisture problem remains undiscovered or is not addressed over a period of time. Some molds may produce airborne toxins or irritants. Indoor air quality issues can
also stem from inadequate ventilation, chemical contamination from indoor or outdoor sources and other biological contaminants such as pollen, viruses and bacteria. Indoor exposure to airborne toxins or irritants above certain levels can be alleged
to cause a variety of adverse health effects and symptoms, including allergic or other reactions. As a result, the presence of significant mold or other airborne contaminants at any of our properties could require us to undertake a costly
remediation program to contain or remove the mold or other airborne contaminants from the affected property or increase indoor ventilation. In addition, the presence of significant mold or other airborne contaminants could expose us to liability
from our tenants, employees of our tenants and others if property damage or health concerns arise.

We may incur
significant costs complying with the Americans with Disabilities Act and similar laws.

Under the Americans with
Disabilities Act of 1990, or the ADA, all public accommodations must meet federal requirements related to access and use by disabled persons. We have not conducted an audit or investigation of all of our properties to determine our compliance with
the ADA. If one or more of the properties in our portfolio does not comply with the ADA, then we would be required to incur additional costs to bring the property into compliance. Additional federal, state and local laws also may require
modifications to our properties, or restrict our ability to renovate our properties. We cannot predict the ultimate cost of compliance with the ADA or other legislation. If we incur substantial costs to comply with the ADA and any other similar
legislation, our financial condition, results of operations, cash flow, cash available for distribution and ability to satisfy our debt service obligations could be materially adversely affected.

We may incur significant costs complying with other regulations.

The properties in our portfolio are subject to various federal, state and local regulations, such as state and local fire and life safety
regulations. If we fail to comply with these various regulations, we may have to pay fines or private damage awards. In addition, we do not know whether existing regulations will change or whether future regulations will require us to make
significant unanticipated expenditures that will materially adversely impact our financial condition, results of operations, cash flow, cash available for distribution and ability to satisfy our debt service obligations.

The conversion rights of Digital Realty Trust, Inc.s preferred stock may be detrimental to holders of Digital Realty Trust,
Inc.s common stock.

Digital Realty Trust, Inc. currently has 11,500,000 shares of 7.000% series E cumulative
redeemable preferred stock outstanding, 7,300,000 shares of 6.625% series F cumulative redeemable preferred stock outstanding and 10,000,000 shares of 5.875% series G cumulative redeemable preferred stock outstanding, which may be converted into
Digital Realty Trust, Inc. common stock upon the occurrence of limited specified change in control transactions. The conversion of series E preferred stock, series F preferred stock or series G preferred stock for Digital Realty Trust, Inc. common
stock would dilute stockholder ownership in Digital Realty Trust, Inc. and unitholder ownership in Digital Realty Trust, L.P., and could adversely affect the market price of Digital Realty Trust, Inc. common stock and could impair our ability to
raise capital through the sale of additional equity securities.

become subject to a variety of risks unique to these activities. If construction costs of a project exceed original estimates, such costs may have to be absorbed by us, which would make the
project less profitable than originally estimated, or possibly not profitable at all. A construction project may be delayed due to government or regulatory approvals, supply shortages, or other events and circumstances beyond our control, or the
time required to complete a construction project may be greater than originally anticipated. In addition, we may be liable for any injuries or damage that arise from worksite accidents, or from the design or construction of the datacenters we build.
If any such excess costs, project delays or liabilities were to be material, such events may adversely affect our financial condition, results of operations and cash available for distribution.

Our business could be adversely impacted if there are deficiencies in our disclosure controls and procedures or internal control over
financial reporting.

The design and effectiveness of our disclosure controls and procedures and internal control over
financial reporting may not prevent all errors, misstatements or misrepresentations. While management will continue to review the effectiveness of our disclosure controls and procedures and internal control over financial reporting, there can be no
guarantee that our internal control over financial reporting will be effective in accomplishing all control objectives all of the time. Furthermore, our disclosure controls and procedures and internal control over financial reporting with respect to
entities that we do not control or manage may be substantially more limited than those we maintain with respect to the subsidiaries that we have controlled or managed over the course of time. Deficiencies, including any material weakness, in our
internal control over financial reporting which may occur in the future could result in misstatements of our results of operations, restatements of our financial statements, a decline in Digital Realty Trust, Inc.s stock price, or otherwise
materially adversely affect our business, reputation, results of operations, financial condition or liquidity.

Risks Related to Our
Organizational Structure

Digital Realty Trust, Inc.s duty to its stockholders may conflict with the interests
of Digital Realty Trust, L.P.s unitholders.

Conflicts of interest may exist or could arise in the future as a result
of the relationships between Digital Realty Trust, Inc. and its affiliates, on the one hand, and our operating partnership or any partner thereof, on the other. Digital Realty Trust, Inc.s directors and officers have duties to Digital Realty
Trust, Inc. and its stockholders under Maryland law in connection with their management of our company. At the same time, Digital Realty Trust, Inc., as general partner, has fiduciary duties under Maryland law to our operating partnership and to the
limited partners in connection with the management of our operating partnership. Digital Realty Trust, Inc.s duties as general partner to our operating partnership and its partners may come into conflict with the duties of Digital Realty
Trust, Inc.s directors and officers to Digital Realty Trust, Inc. and its stockholders. Under Maryland law, a general partner of a Maryland limited partnership owes its limited partners the duties of loyalty and care, which must be discharged
consistently with the obligation of good faith and fair dealing, unless the partnership agreement provides otherwise. The partnership agreement of our operating partnership provides that for so long as Digital Realty Trust, Inc. owns a controlling
interest in our operating partnership, any conflict that cannot be resolved in a manner not adverse to either Digital Realty Trust, Inc.s stockholders or the limited partners will be resolved in favor of Digital Realty Trust, Inc.s
stockholders.

The provisions of Maryland law that allow the fiduciary duties of a general partner to be modified by a
partnership agreement have not been tested in a court of law, and we have not obtained an opinion of counsel covering the provisions set forth in the partnership agreement that purport to waive or restrict Digital Realty Trust, Inc.s fiduciary
duties.

Digital Realty Trust, Inc.s stockholders and Digital Realty Trust, L.P.s
unitholders are also subject to the following additional conflict of interest:

Tax consequences upon sale or
refinancing.Sales of properties and repayment of certain indebtedness will affect holders of common units in our operating partnership and Digital Realty Trust, Inc.s stockholders differently. Consequently, these holders of common
units in our operating partnership may have different objectives regarding the appropriate pricing and timing of any such sale or repayment of debt. While Digital Realty Trust, Inc. has exclusive authority under the limited partnership agreement of
our operating partnership to determine when to refinance or repay debt or whether, when, and on what terms to sell a property, any such decision would require the approval of Digital Realty Trust, Inc.s board of directors. Certain of Digital
Realty Trust, Inc.s directors and executive officers could exercise their influence in a manner inconsistent with the interests of some, or a majority, of Digital Realty Trust, L.P.s unitholders, including in a manner which could prevent
completion of a sale of a property or the repayment of indebtedness.

Digital Realty Trust, Inc.s charter, Digital
Realty Trust, L.P.s partnership agreement and Maryland law contain provisions that may delay, defer or prevent a change of control transaction.

Digital Realty Trust, Inc.s charter and the articles supplementary with respect to the preferred stock contain 9.8% ownership limits.Digital Realty Trust, Inc.s charter, subject
to certain exceptions, authorizes the companys directors to take such actions as are necessary and desirable to preserve the companys qualification as a REIT and to limit any person to actual or constructive ownership of no more than
9.8% (by value or by number of shares, whichever is more restrictive) of the outstanding shares of the companys common stock, 9.8% (by value or by number of shares, whichever is more restrictive) of the outstanding shares of any series of
preferred stock and 9.8% of the value of the companys outstanding capital stock. Digital Realty Trust, Inc.s board of directors, in its sole discretion, may exempt (prospectively or retroactively) a proposed transferee from the ownership
limit. However, Digital Realty Trust, Inc.s board of directors may not grant an exemption from the ownership limit to any proposed transferee whose direct or indirect ownership of more than 9.8% of the outstanding shares of the companys
common stock, more than 9.8% of the outstanding shares of any series of preferred stock or more than 9.8% of the value of the companys outstanding capital stock could jeopardize the companys status as a REIT. These restrictions on
transferability and ownership will not apply if Digital Realty Trust, Inc.s board of directors determines that it is no longer in the companys best interests to attempt to qualify, or to continue to qualify, as a REIT or that compliance
is no longer required for REIT qualification. The ownership limit may delay, defer or prevent a transaction or a change of control that might be in the best interest of Digital Realty Trust, Inc.s stockholders and Digital Realty Trust,
L.P.s unitholders.

Digital Realty Trust, L.P.s partnership agreement contains provisions that may delay,
defer or prevent a change of control transaction.Digital Realty Trust, L.P.s partnership agreement provides that Digital Realty Trust, Inc. may not engage in any merger, consolidation or other combination with or into another person,
any sale of all or substantially all of its assets or any reclassification, recapitalization or change of its outstanding equity interests unless the transaction is approved by the holders of common units and long term incentive units representing
at least 35% of the aggregate percentage interests of all holders of common units and long-term incentive units and either:

| |  |  | the rights of the limited partners or non-managing members of the surviving partnership include at least one of the following: (i) the right to
redeem their interests in the surviving partnership for the consideration available to such persons pursuant to Digital Realty Trust, L.P.s partnership agreement; or (ii) the right to redeem their interests for cash on terms equivalent to
those in effect with respect to their common units immediately prior to the consummation of such transaction (or, if the ultimate controlling person of the surviving partnership has publicly traded common equity securities, for such common equity
securities, with an exchange ratio based on the determination of relative fair market value of such securities and the shares of Digital Realty Trust, Inc. common stock).

These provisions may discourage others from trying to acquire control of Digital Realty Trust, Inc. and may delay, defer or prevent a
change of control transaction that might be beneficial to Digital Realty Trust, Inc.s stockholders and Digital Realty Trust, L.P.s unitholders.

The change of control conversion features of Digital Realty Trust, Inc.s preferred stock may make it more difficult for a party to take over our company or discourage a party from taking over
our company.

Upon the occurrence of specified change of control transactions, holders of our series E preferred stock,
series F preferred stock and series G preferred stock will have the right (unless, prior to the change of control conversion date, we have provided or provide notice of our election to redeem such preferred stock) to convert some or all of their
series E or series F preferred stock, as applicable, into shares of our common stock (or equivalent value of alternative consideration), subject to caps set forth in the articles supplementary governing the applicable series of preferred stock. The
change of control conversion features of the series E preferred stock, series F preferred stock and series G preferred stock may have the effect of discouraging a third party from making an acquisition proposal for our company or of delaying,
deferring or preventing certain change of control transactions of our company under circumstances that otherwise could provide the holders of our common stock, series E preferred stock, series F preferred stock and series G preferred stock with the
opportunity to realize a premium over the then-current market price or that stockholders may otherwise believe is in their best interests.

Digital Realty Trust, Inc. could increase or decrease the number of authorized shares of stock and issue stock without stockholder approval.Digital Realty Trust, Inc.s charter
authorizes the companys board of directors, without stockholder approval, to amend the charter from time to time to increase or decrease the aggregate number of authorized shares of stock or the number of authorized shares of stock of any
class or series, to issue authorized but unissued shares of the companys common stock or preferred stock into other classes or series of stock and, subject to the voting rights of holders of preferred stock, to classify or reclassify any
unissued shares of the companys common stock or preferred stock and to set the preferences, rights and other terms of such classified

or reclassified shares. Although Digital Realty Trust, Inc.s board of directors has no such intention at the present time, it could establish an additional class or series of preferred
stock that could, depending on the terms of such class or series, delay, defer or prevent a transaction or a change of control that might be in the best interest of Digital Realty Trust, Inc.s stockholders and Digital Realty Trust, L.P.s
unitholders.

Certain provisions of Maryland law could inhibit changes in control. Certain provisions of the
Maryland General Corporation Law, or MGCL, may have the effect of impeding a third party from making a proposal to acquire Digital Realty Trust, Inc. or of impeding a change of control under circumstances that otherwise could be in the best
interests of Digital Realty Trust, Inc.s stockholders and Digital Realty Trust, L.P.s unitholders, including:



| |  |  | business combination provisions that, subject to limitations, prohibit certain business combinations between Digital Realty Trust, Inc. and
an interested stockholder (defined generally as any person who beneficially owns 10% or more of the voting power of the companys outstanding shares of voting stock or an affiliate or associate of the company who, at any time within
the two-year period prior to the date in question, was the beneficial owner of 10% or more of the voting power of the companys then outstanding shares of stock) or an affiliate thereof for five years after the most recent date on which the
stockholder becomes an interested stockholder, and thereafter imposes special appraisal rights and supermajority voting requirements on these combinations; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | control share provisions that provide that control shares of Digital Realty Trust, Inc. (defined as shares which, when
aggregated with other shares controlled by the stockholder (except solely by virtue of a revocable proxy), entitle the stockholder to exercise one of three increasing ranges of voting power in electing directors) acquired in a control share
acquisition (defined as the direct or indirect acquisition of ownership or control of issued and outstanding control shares) have no voting rights except to the extent approved by the companys stockholders by the affirmative
vote of at least two-thirds of all the votes entitled to be cast on the matter, excluding all interested shares.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Digital Realty Trust, Inc. has opted out of these provisions of the MGCL, in the case of the business combination provisions of the MGCL by resolution of its board of directors, and in the case of the
control share provisions of the MGCL pursuant to a provision in its bylaws. However, Digital Realty Trust, Inc.s board of directors may by resolution elect to opt in to the business combination provisions of the MGCL and the company may, by
amendment to its bylaws, opt in to the control share provisions of the MGCL in the future.

The provisions of Digital Realty
Trust, Inc.s charter on removal of directors and the advance notice provisions of Digital Realty Trust, Inc.s bylaws could delay, defer or prevent a transaction or a change of control of the company that might be in the best interest of
Digital Realty Trust, Inc.s stockholders and Digital Realty Trust, L.P.s unitholders. Likewise, if Digital Realty Trust, Inc.s board of directors were to opt in to the business combination provisions of the MGCL or the provisions
of Title 3, Subtitle 8 of the MGCL not currently applicable to the company, or if the provision in the Digital Realty Trust, Inc.s bylaws opting out of the control share acquisition provisions of the MGCL were rescinded, these provisions of
the MGCL could have similar anti-takeover effects.

Digital Realty Trust, Inc.s board of directors may change our
investment and financing policies without stockholder approval or approval of Digital Realty Trust, L.P.s other partners and we may become more highly leveraged, which may increase our risk of default under our debt obligations.

Digital Realty Trust, Inc.s board of directors adopted a policy limiting our indebtedness to 60% of our total
enterprise value. 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 capitalization ratio), excluding options
issued under our incentive award plan, plus the aggregate value of Digital Realty Trust, L.P. units not held by Digital Realty Trust, Inc. (with the per unit value equal to the market value of one share of Digital Realty Trust, Inc. common stock and
excluding long-term incentive units and Class C units), plus the liquidation preference of Digital Realty Trust, Inc.s outstanding preferred stock, plus the book value of our total

consolidated indebtedness. However, the organizational documents of Digital Realty Trust, Inc. and Digital Realty Trust, L.P. do not limit the amount or percentage of indebtedness, funded or
otherwise, that we may incur. Digital Realty Trust, Inc.s board of directors may alter or eliminate our current policy on borrowing at any time without stockholder or unitholder approval. If this policy changed, we could become more highly
leveraged which could result in an increase in our debt service and which could materially adversely affect our cash flow and our ability to pay dividends to Digital Realty Trust, Inc.s stockholders or distributions to Digital Realty Trust,
L.P.s unitholders. Higher leverage also increases the risk of default on our obligations.

Digital Realty Trust,
Inc.s rights and the rights of its stockholders to take action against its directors and officers are limited.

Maryland law provides that Digital Realty Trust, Inc.s directors have no liability in their capacities as directors if they perform
their duties in good faith, in a manner they reasonably believe to be in the companys best interests and with the care that an ordinarily prudent person in a like position would use under similar circumstances. As permitted by the MGCL,
Digital Realty Trust, Inc.s charter limits the liability of the companys directors and officers to the company and its stockholders for money damages, except for liability resulting from:



| |  |  | actual receipt of an improper benefit or profit in money, property or services; or
| | - |  | ----------------------------------------------------------------------------------



| |  |  | a final judgment based upon a finding of active and deliberate dishonesty by the director or officer that was material to the cause of action
adjudicated.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, Digital Realty Trust, Inc.s charter authorizes the company to obligate
itself, and the companys bylaws require it, to indemnify the companys directors and officers for actions taken by them in those capacities and to pay or reimburse their reasonable expenses in advance of final disposition of a proceeding
to the maximum extent permitted by Maryland law and Digital Realty Trust, Inc. has entered into indemnification agreements with its officers and directors. As a result, Digital Realty Trust, Inc. and its stockholders may have more limited rights
against its directors and officers than might otherwise exist under common law. Accordingly, in the event that actions taken in good faith by any of Digital Realty Trust, Inc.s directors or officers impede the performance of the company, the
companys stockholders ability to recover damages from that director or officer will be limited.

Risks Related to Taxes and
Digital Realty Trust, Inc.s Status as a REIT

Failure to qualify as a REIT would have significant adverse
consequences to Digital Realty Trust, Inc. and its stockholders and to Digital Realty Trust, L.P. and its unitholders.

Digital Realty Trust, Inc. has operated and intends to continue operating in a manner that it believes will allow it to qualify as a REIT
for federal income tax purposes under the Code. Digital Realty Trust, Inc. has not requested and does not plan to request a ruling from the IRS that it qualifies as a REIT. Qualification as a REIT involves the application of highly technical and
complex Code provisions for which there are only limited judicial and administrative interpretations. The complexity of these provisions and of the applicable Treasury Regulations that have been promulgated under the Code is greater in the case of a
REIT that, like Digital Realty Trust, Inc., holds its assets through a partnership. The determination of various factual matters and circumstances not entirely within Digital Realty Trust, Inc.s control may affect its ability to qualify as a
REIT. In order to qualify as a REIT, Digital Realty Trust, Inc. must satisfy a number of requirements, including requirements regarding the ownership of its stock, requirements regarding the composition of its assets and a requirement that at least
95% of its gross income in any year must be derived from qualifying sources, such as rents from real property. Also, Digital Realty Trust, Inc. must make distributions to stockholders aggregating annually at least 90% of its net taxable
income, excluding any net capital gains.

##### Table of Contents

If Digital Realty Trust, Inc. loses its REIT status, it will face serious tax consequences
that would substantially reduce its cash available for distribution, including cash available to pay dividends to its stockholders, for each of the years involved because:



| |  |  | Digital Realty Trust, Inc. would not be allowed a deduction for dividends paid to stockholders in computing its taxable income and would be subject to
federal income tax at regular corporate rates;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Digital Realty Trust, Inc. also could be subject to the federal alternative minimum tax and possibly increased state and local taxes; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | unless Digital Realty Trust, Inc. is entitled to relief under applicable statutory provisions, it could not elect to be taxed as a REIT for four
taxable years following the year during which it was disqualified.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, if Digital Realty Trust,
Inc. fails to qualify as a REIT, it will not be required to make distributions to stockholders, and accordingly, distributions Digital Realty Trust, L.P. makes to its unitholders could be similarly reduced. As a result of all these factors, Digital
Realty Trust, Inc.s failure to qualify as a REIT also could impair our ability to expand our business and raise capital, and would materially adversely affect the value of Digital Realty Trust, Inc.s stock and Digital Realty Trust,
L.P.s units.

In certain circumstances, Digital Realty Trust, Inc. may be subject to federal and state taxes as a
REIT, which would reduce its cash available for distribution to its stockholders.

Even if Digital Realty Trust, Inc.
qualifies as a REIT for federal income tax purposes, it may be subject to some federal, state and local taxes on its income or property and, in certain cases, a 100% penalty tax, in the event it sells property as a dealer. In addition, our domestic
corporate subsidiary, Digital Services, Inc., which is a taxable REIT subsidiary of Digital Realty Trust, Inc., could be subject to federal and state taxes, and our foreign properties and companies are subject to tax in the jurisdictions in which
they operate and are located. Any federal, state or other taxes Digital Realty Trust, Inc. pays will reduce its cash available for distribution to stockholders.

To maintain Digital Realty Trust, Inc.s REIT status, we may be forced to borrow funds during unfavorable market conditions.

To qualify as a REIT, Digital Realty Trust, Inc. generally must distribute to its stockholders at least 90% of its net taxable income each
year, excluding capital gains, and Digital Realty Trust, Inc. will be subject to regular corporate income taxes to the extent that it distributes less than 100% of its net taxable income each year. In addition, Digital Realty Trust, Inc. will be
subject to a 4% nondeductible excise tax on the amount, if any, by which distributions paid by Digital Realty Trust, Inc. in any calendar year are less than the sum of 85% of its ordinary income, 95% of its capital gain net income and 100% of its
undistributed income from prior years. While historically Digital Realty Trust, Inc. has satisfied these distribution requirements by making cash distributions to its stockholders, a REIT is permitted to satisfy these requirements by making
distributions of cash or other property. We may need to borrow funds for Digital Realty Trust, Inc. to meet the REIT distribution requirements even if the then prevailing market conditions are not favorable for these borrowings. These borrowing
needs could result from differences in timing between the actual receipt of cash and inclusion of income for federal income tax purposes, or the effect of non-deductible capital expenditures, the creation of reserves or required debt or amortization
payments.

Dividends payable by REITs do not qualify for the reduced tax rates available for some dividends.

Income from qualified dividends payable to U.S. stockholders that are individuals, trusts and estates are
generally subject to tax at preferential rates. Dividends payable by REITs, however, generally are not eligible for the preferential tax rates applicable to qualified dividend income. Although these rules do not adversely affect the taxation of
REITs or dividends payable by REITs, to the extent that the preferential rates continue to apply to regular corporate qualified dividends, investors who are individuals, trusts and estates may perceive investments

in REITs to be relatively less attractive than investments in the stocks of non-REIT corporations that pay dividends, which could materially and adversely affect the value of the shares of REITs,
including the per share trading price of Digital Realty Trust, Inc.s capital stock.

The tax imposed on REITs
engaging in prohibited transactions may limit our ability to engage in transactions which would be treated as sales for federal income tax purposes.

A REITs net income from prohibited transactions is subject to a 100% penalty tax. In general, prohibited transactions are sales or other dispositions of property, other than foreclosure property,
held primarily for sale to customers in the ordinary course of business. Although we do not intend to hold any properties that would be characterized as held for sale to customers in the ordinary course of our business, unless a sale or disposition
qualifies under certain statutory safe harbors, such characterization is a factual determination and no guarantee can be given that the IRS would agree with our characterization of our properties or that we will always be able to make use of the
available safe harbors.

Complying with REIT requirements may cause us to forego otherwise attractive opportunities or
liquidate otherwise attractive investments.

To qualify as a REIT for federal income tax purposes, Digital Realty Trust,
Inc. must continually satisfy tests concerning, among other things, its sources of income, the nature and diversification of its assets (including its proportionate share of Digital Realty Trust, L.P.s assets), the amounts it distributes to
its stockholders and the ownership of its capital stock. If Digital Realty Trust, Inc. fails to comply with one or more of the asset tests at the end of any calendar quarter, it must correct the failure within 30 days after the end of the calendar
quarter or qualify for certain statutory relief provisions to avoid losing its REIT qualification and suffering adverse tax consequences. In order to meet these tests, we may be required to forego investments we might otherwise make or to liquidate
otherwise attractive investments. Thus, compliance with the REIT requirements may hinder our performance and reduce amounts available for distribution to Digital Realty Trust, Inc.s stockholders and Digital Realty Trust, L.P.s
unitholders.

Legislative or other actions affecting REITs could have a negative effect on us.

The rules dealing with federal income taxation are constantly under review by persons involved in the legislative process and by the IRS
and the U.S. Department of the Treasury. Changes to the tax laws, with or without retroactive application, could materially and adversely affect Digital Realty Trust, Inc.s stockholders, Digital Realty Trust, L.P.s unitholders and/or us.
We cannot predict how changes in the tax laws might affect our investors and/or us. New legislation, Treasury Regulations, administrative interpretations or court decisions could significantly and negatively affect Digital Realty Trust, Inc.s
ability to qualify as a REIT or the federal income tax consequences of such qualification.

The power of Digital Realty
Trust, Inc.s board of directors to revoke Digital Realty Trust, Inc.s REIT election without stockholder approval may cause adverse consequences to Digital Realty Trust, Inc.s stockholders and Digital Realty Trust, L.P.s
unitholders.

Digital Realty Trust, Inc.s charter provides that its board of directors may revoke or otherwise
terminate its REIT election, without the approval of its stockholders, if it determines that it is no longer in Digital Realty Trust, Inc.s best interests to continue to qualify as a REIT. If Digital Realty Trust, Inc. ceases to qualify as a
REIT, it would become subject to U.S. federal income tax on its taxable income and it would no longer be required to distribute most of its taxable income to its stockholders and accordingly, distributions Digital Realty Trust, L.P. makes to its
unitholders could be similarly reduced.

Forward-Looking Statements

We make statements in this report that are forward-looking statements within the meaning of the federal securities laws. In particular, statements pertaining to our capital resources, portfolio
performance including our ability to lease vacant space and space under development, leverage policy and acquisition and capital expenditure plans, 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 which do not relate solely to historical matters. You can also
identify forward-looking statements by discussions of strategy, plans or intentions.

##### Table of Contents

Lease Expirations

The following table sets forth a summary schedule of the lease expirations for leases in place as of December 31, 2013 plus available space for ten calendar years at the properties in our portfolio,
excluding approximately 1.8 million square feet of space under active development and approximately 1.3 million square feet of space held for future development at December 31, 2013. Unless otherwise stated in the footnotes, the
information set forth in the table assumes that tenants exercise no renewal options and all early termination rights (dollar amounts in thousands).

October 29, 2004. The following table sets forth, for the periods indicated, the high and low last sale prices in dollars on the NYSE for our common stock and the distributions we declared with respect to the periods indicated.

Digital Realty Trust, Inc. intends to continue to declare quarterly dividends on its common stock. The
actual amount, form and timing of dividends, however, will be at the discretion of the board of directors and will depend upon Digital Realty Trust, Inc.s financial condition in addition to the requirements for qualification as a REIT under
the Code, and no assurance can be given as to the amounts, form or timing of future dividends. The exchange rate on the 2029 debentures is subject to adjustment for certain events, including, but not limited to, certain dividends on Digital Realty
Trust, Inc.s common stock in excess of $0.33 per share per quarter. Therefore, the declaration and payment of quarterly dividends by Digital Realty Trust, Inc. in excess of this threshold may increase the dilutive impact of our operating
partnerships exchangeable debentures on Digital Realty Trust, Inc.s common stockholders. See Part I, Item 1A, Risk Factors, Risks Related to Our Business and OperationsWe have substantial debt and face risks associated
with the use of debt to fund our business activities, including refinancing and interest rate risksThe exchange and repurchase rights of our exchangeable debentures may be detrimental to Digital Realty Trust, Inc.s stockholders or
Digital Realty Trust, L.P.s unitholders and Risks Related to Our Business and OperationsThe conversion rights of Digital Realty Trust, Inc.s convertible preferred stock may be detrimental to holders of Digital Realty
Trust, Inc.s common stock. In addition, our global revolving credit facility, our Prudential shelf facility and our term loan facility prohibit us from making distributions to our stockholders, or redeeming or otherwise repurchasing
shares of our capital stock, including our common stock, after the occurrence and during the continuance of an event of default, except in limited circumstances including as necessary to enable us to maintain our qualification as a REIT and to avoid
the payment of income or excise tax. Consequently, after the occurrence and during the continuance of an event of default under our global revolving credit facility, Prudential shelf facility or term loan facility, we may not be able to pay all or a
portion of the dividends payable to the holders of our common stock.

Subject to the distribution requirements applicable to
REITs under the Code, Digital Realty Trust, Inc. intends, to the extent practicable, to invest substantially all of the proceeds from sales and refinancings of its assets in real estate-related assets and other assets. Digital Realty Trust, Inc.
may, however, under certain circumstances, make a dividend of capital or of assets. Such dividends, if any, will be made at the discretion of the board of directors.

As of February 20, 2014, there were approximately 143 holders of record of Digital Realty Trust, Inc.s common stock. This figure does not reflect the beneficial ownership of shares held in
nominee name.

holders of its common units. Any future distributions will be declared at the discretion of the board of directors of Digital Realty Trust, L.P.s general partner, Digital Realty Trust, Inc., and will depend on our actual cash flow, financial
condition, capital requirements, the annual distribution requirements under the REIT provisions of the Code, and such other factors as the board of directors may deem relevant.

|ITEM 7. | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
|------- | -------------------------------------------------------------------------------------

The following discussion should be read in conjunction with the consolidated financial statements and notes thereto appearing elsewhere
in this report. We make statements in this section that are forward-looking statements within the meaning of the federal securities laws. For a complete discussion of forward-looking statements, see the section in this report entitled
Forward-Looking Statements. Certain risk factors may cause our actual results, performance or achievements to differ materially from those expressed or implied by the following discussion. For a discussion of such risk factors, see the
sections in this report entitled Risk Factors and Forward-Looking Statements.

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.

Overview

Our
company. Digital Realty Trust, Inc. completed its initial public offering of common stock, or our IPO, on November 3, 2004. We believe that we have operated in a manner that has enabled us to qualify, and have elected to be treated, as a
REIT under Sections 856 through 860 of the Code. Our company was formed on March 9, 2004. During the period from our formation until we commenced operations in connection with the completion of our IPO, we did not have any corporate activity
other than the issuance of shares of Digital Realty Trust, Inc. common stock in connection with the initial capitalization of the company. Our operating partnership was formed on July 21, 2004.

Business and strategy. Our primary business objectives are to maximize: (i) sustainable long-term growth in earnings and
funds from operations per share and unit and (ii) cash flow and returns to our stockholders and our operating partnerships unitholders through the payment of distributions. We expect to achieve our objectives by focusing on our core
business of investing in and developing technology-related real estate. A significant component of our current and future internal growth is anticipated through the development of our existing space held for development and acquisition of new
properties. We target high quality, strategically located properties containing applications and operations critical to the day-to-day operations of corporate enterprise datacenter and technology industry tenants and properties that may be developed
for such use. Most of our properties contain fully redundant electrical supply systems, multiple power feeds, above-standard precision cooling systems, raised floor areas, extensive in-building communications cabling and high-level security systems.
We focus solely on technology-related real estate because we believe that the growth in corporate datacenter adoption and the technology-related real estate industry generally will continue to be superior to that of the overall economy.

As of December 31, 2013, we owned an aggregate of 131 properties, including 12 properties held as investments
in unconsolidated joint ventures, with approximately 24.5 million rentable square feet including approximately 1.8 million square feet of space under active development and approximately 1.3 million square feet of space held for future
development. The 12 properties held as investments in unconsolidated joint ventures have an aggregate of approximately 1,512,000 rentable square feet. The 11 parcels of developable land we own comprised approximately 154 acres. At
December 31, 2013, approximately 1,760,000 square feet was under construction for Turn-Key Flex®, Powered
Base Building® and Custom Solutions (formerly referred to as Build-to-Suit) products, all of which are expected
to be income producing on or after completion, in eight U.S. domestic markets, three European markets, one Canadian market and one Australian market, consisting of approximately 1,063,000 square feet of base building construction and 697,000 square
feet of data center construction.

We have developed detailed, standardized procedures for evaluating acquisitions to ensure
that they meet our financial, technical and other criteria. We expect to continue to acquire additional assets as a 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 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 currently intend to
limit our indebtedness to 60% of our total enterprise value and, based on the closing price of Digital Realty Trust, Inc. common stock on December 31, 2013 of $49.12, our ratio of debt to total enterprise value was approximately 41%. 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), excluding options issued under our
companys incentive award plan, plus the liquidation value of Digital Realty Trust, Inc.s preferred stock, plus the aggregate value of our operating partnership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. common stock and excluding long-term incentive units and Class C units), plus the book value of our total consolidated indebtedness.

Revenue base. As of December 31, 2013, we owned 131 properties through our operating partnership, including 12 properties
held as investments in unconsolidated joint ventures and developable land. These properties are mainly located throughout the U.S., with 22 properties located in Europe, three properties in Australia, two properties in Canada and two properties in
Asia. We, through our predecessor, acquired our first portfolio property in January 2002 and have added properties as follows:

|(8) | 43790 Devin Shafron Drive and 21551 Beaumeade Circle, which were previously included as part of the Devin Shafron buildings and Beaumeade Portfolio, respectively, are
now each separately included in the property count because they were separately contributed to an unconsolidated joint venture in September 2013.

In May 2008, we acquired 701 & 717 Leonard Street, a parking garage in Dallas, Texas; however, we exclude the acquisition from our property count because it is located adjacent to our internet
gateway datacenter located at 2323 Bryan Street and is not considered a separate property.

On
September 27, 2013, we formed a joint venture with an investment fund managed by Prudential Real Estate Investors
(PREI®). We contributed nine Powered Base Building® data centers totaling 1.06 million square feet and valued at approximately $366.4 million (excluding $2.8 million of closing costs). The PREI®-managed fund took an 80% interest in the joint venture and we retained a 20% interest. The joint venture is
structured to provide a current annual preferred return from cash flow first to the PREI®-managed interest, then
to our interest, after which a portion of any excess cash flows is shared by the partners based on their respective interests and the remaining portion is paid to us as a promote interest. We perform the day-to-day accounting and property management
functions for the joint venture and, as such, we earn a management fee for the services provided. Although we are the managing member of the joint venture and manage the day-to-day activities, all significant decisions, including approval of annual
budgets and setting the amount of our management fees require approval of the PREI® member. Thus we concluded we
do not own a controlling interest and will account for our interest in the joint venture as an equity method investment, which will result in a reduction in same-store revenues and net income from these properties on our income statement relative to
historical periods.

As of December 31, 2013, the properties in our portfolio, including the 12 properties held as
investments in unconsolidated joint ventures, were approximately 92.6% leased excluding approximately 1.8 million square feet of space under active development and approximately 1.3 million square feet of space held for future development. Due
to the capital-intensive and long-term nature of the operations being supported, our lease terms are generally longer than standard commercial leases. As of December 31, 2013, our original average lease term was approximately 12 years, with an
average of approximately seven years remaining. Our lease expirations through December 31, 2015 are 14.3% of rentable square feet excluding space under active development and space held for future development as of December 31, 2013.

Factors Which May Influence Future Results of Operations

Global market and economic conditions

United States and international
market and economic conditions over the past several years have been unprecedented and challenging with tighter credit conditions and slower economic growth in many markets in which we own properties and conduct our operations. The U.S. and global
economies have experienced a recession and face continued concerns about the systemic impact of adverse economic conditions, such as high energy costs, geopolitical issues, the availability and cost of credit, unstable global financial and mortgage
markets, high corporate, consumer and governmental debt levels, ongoing sovereign debt and economic issues in

European countries, concerns regarding the U.S. budget deficit, debt ceiling, spending cuts and the possibility of further downgrades to the U.S. governments credit rating, high
unemployment and declining residential and commercial real estate markets. The European debt crisis has raised concerns regarding the debt burden of certain countries using the euro as their currency and their ability to meet future financial
obligations, the overall stability of the euro and the suitability of the euro as a single currency given the diverse economic and political circumstances in individual eurozone countries. These concerns could lead to the re-introduction of
individual currencies in one or more eurozone countries, or, in more extreme circumstances, the possible dissolution of the euro currency entirely. Should the euro be dissolved entirely, the legal and contractual consequences for parties to
euro-denominated contracts are uncertain and would be determined by laws in effect at such time. These potential developments, or market perceptions concerning these and related issues, could adversely affect our leasing and financing activities,
rents we receive, potential acquisitions and development projects in Europe.

As a result of these conditions, general
economic conditions and the cost and availability of capital have been and may again be adversely affected in some or all of the markets in which we own properties and conduct our operations. Renewed or increased turbulence in the U.S., European,
Asia Pacific and other international financial markets and economies may adversely affect our ability, and the ability of our tenants, to replace or renew maturing liabilities on a timely basis, access the capital markets to meet liquidity and
capital expenditure requirements and may result in adverse effects on our, and our tenants, financial condition and results of operations.

In addition, our access to funds under our global revolving credit facility depend on the ability of the lenders that are parties to such facilities to meet their funding commitments to us. We cannot
assure you that long-term disruptions in the global economy and the return of tighter credit conditions among, and potential failures or nationalizations of, third party financial institutions as a result of such disruptions will not have an adverse
effect on our lenders. If our lenders are not able to meet their funding commitments to us, our business, results of operations, cash flows and financial condition could be adversely affected.

If we do not have sufficient cash flow to continue operating our business and are unable to borrow additional funds, access our existing
lines of credit or raise equity or debt capital, we may need to source alternative ways to increase our liquidity. Such alternatives may include, without limitation, curtailing development activity, disposing of one or more of our properties
possibly on disadvantageous terms or entering into or renewing leases on less favorable terms than we otherwise would.

Rental income. The amount of rental income generated by the properties in our portfolio depends on several factors, including our
ability to maintain or improve the occupancy rates of currently leased space and to lease currently available space and space available from lease terminations. Excluding approximately 1.8 million square feet of space under active development
and approximately 1.3 million square feet of space held for future development as of December 31, 2013, the occupancy rate of the properties in our portfolio, including the 12 properties held as investments in unconsolidated joint ventures, was
approximately 92.6% of our net rentable square feet.

As of December 31, 2013, we had 2,263 leases with a total of 655
tenants in our portfolio, including the ten properties held in our managed portfolio of unconsolidated joint ventures. As of December 31, 2013, approximately 88% of our leases (on a rentable square footage basis) contained base rent escalations
that were either fixed (generally ranging from 2% to 4%) or indexed based on a consumer price index or other similar inflation related index. We cannot assure you that these escalations will cover any increases in our costs or will otherwise keep
rental rates at or above market rates.

The amount of rental income generated by us also depends on maintaining or increasing
rental rates at our properties, which in turn depends on several factors, including supply and demand and market rates for data center space. Included in our approximately 19.9 million net rentable square feet, excluding space under active
development and space held for future development and 12 properties held as investments in unconsolidated joint

ventures, at December 31, 2013 is approximately 676,000 square feet of datacenter space with extensive installed tenant improvements available for lease. Since our IPO, we have leased
approximately 4.5 million square feet of similar space, including Turn-Key Flex® space. Our Turn-Key Flex® product is an effective solution for tenants who prefer to utilize a partner with the expertise or capital budget to provide extensive datacenter infrastructure and
security. Our expertise in datacenter construction and operations enables us to lease space to these tenants at a premium over other uses. In addition, as of December 31, 2013, we had approximately 1.8 million square feet of space under
active development and approximately 1.3 million square feet of space held for future development, or approximately 13% of the total rentable space in our portfolio, including one vacant property comprising approximately 128,000 square feet and the
12 properties held as investments in unconsolidated joint ventures. Our ability to grow earnings depends in part on our ability to develop space and lease development space at favorable rates, which we may not be able to obtain. Development space
requires significant capital investment in order to develop datacenter facilities that are ready for use and, in addition, we may require additional time or encounter delays in securing tenants for development space. We may purchase additional
vacant properties and properties with vacant development space in the future. We will require additional capital to finance our development activities, which may not be available or may not be available on terms acceptable to us, including as a
result of the conditions described above under Global market and economic conditions.

In addition, the timing
between when we sign a new lease with a tenant and when that lease commences and we begin to generate rental income may be significant and may not be easily predictable. Certain leases may provide for staggered commencement dates for additional
space, the timing of which may be delayed significantly.

Economic downturns, including as a result of the conditions
described above under Global market and economic conditions, or regional downturns affecting our markets or downturns in the technology-related real estate industry that impair our ability to lease or renew or re-lease space, or
otherwise reduce returns on our investments or the ability of our tenants to fulfill their lease commitments, as in the case of tenant bankruptcies, could adversely affect our ability to maintain or increase rental rates at our properties.

Scheduled lease expirations.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. In addition to approximately 1.6 million square feet of available space in our portfolio, which excludes approximately 1.8 million square feet of space under active development and
approximately 1.3 million square feet of space held for future development as of December 31, 2013 and the two properties held as investments in our non-managed unconsolidated joint ventures, leases representing approximately 4.9% and 9.4% of
the net rentable square footage of our portfolio are scheduled to expire during the years ending December 31, 2014 and 2015, respectively.

|(1) | The number of leases represents the leased-unit count; a lease could include multiple units.

common area.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(3) | Rental rates represent annual estimated cash rent per rentable square foot adjusted for straight-line rents in accordance with GAAP. GAAP rental rates are inclusive of
tenant concessions, if any.

Our ability to re-lease or renew expiring space at rental rates equal to or in excess of current rental rates will
impact our results of operations. We continue to see strong demand in most of our key markets for datacenter space and, subject to the supply of available datacenter space in these markets, expect the rental rates we are likely to achieve on any
new, re-leased or renewed datacenter space leases for 2014 expirations on an average aggregate basis will generally be higher than the rates currently being paid for the same space on a GAAP basis and flat on a cash basis. For the year ended
December 31, 2013, rents on renewed space increased by an average of 5.2% on a GAAP basis on our Turn-Key
Flex® space compared to the expiring rents and increased by an average of 40.0% on a GAAP basis on our Powered
Base Building® space compared to the expiring rents. Our past performance may not be indicative of future
results, and we cannot assure you that leases will be renewed or that our properties 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 market 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 real estate conditions, local supply and demand for datacenter space, competition from other
datacenter developers or operators, the condition of the property and whether the property, or space within the property, has been developed.

|(1) | Annualized rent is monthly contractual rent (defined as cash base rent before abatements) under existing leases as of December 31, 2013 multiplied by 12. The
aggregate amount of abatements for the year ended December 31, 2013 was approximately $33.3 million.

Operating expenses.Our operating expenses generally consist of utilities, property and ad valorem taxes, property management fees, insurance and site maintenance costs, as well as rental expenses
on our ground and building leases. In particular, our buildings require significant power to support the datacenter operations contained in them. Many of our leases contain provisions under which the tenants reimburse us for a portion of property
operating expenses and real estate taxes incurred by us. However, we generally 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 also incur general and administrative expenses, including expenses relating to our asset management
function, as well as significant legal, accounting and other expenses related to corporate governance, SEC reporting and compliance with the various provisions of the Sarbanes-Oxley Act. Increases or decreases in such operating expenses will impact
our overall performance. We expect to incur additional operating expenses as we continue to expand.

Climate change
legislation. In June 2009, the U.S. House of Representatives approved comprehensive clean energy and climate change legislation intended to cut greenhouse gas, or GHG, emissions, create new clean energy jobs and enhance the energy independence
of the United States, which included a cap-and-trade program for GHG emissions. The U.S. Senate did not subsequently pass similar legislation. New climate change legislation was introduced in the U.S. Senate in 2013, but significant opposition to
federal climate change legislation exists. As a result, near-term action to reduce GHG emissions likely will be focused on regulatory agencies, primarily the U.S. Environmental Protection Agency, or EPA, and state actions. The EPA has been moving
aggressively to regulate GHG emissions from automobiles and large stationary sources, including electricity producers, using its own authority under the Clean Air Act. The EPA made an endangerment finding in 2009 that allows it to create regulations
imposing emission reporting, permitting, control technology installation, and monitoring requirements applicable to certain emitters of GHGs, including facilities that provide electricity to our data centers, although the materiality of the impacts
will not be known until all regulations are finalized.

The EPA has already finalized its GHG reporting rule, which requires that
certain emitters, including electricity generators, monitor and report GHG emissions. The EPA has also finalized its tailoring rule, which imposes permitting and control technology requirements upon certain newly-constructed or modified
facilities which emit GHGs under the Clean Air Act New Source Review Prevention of Significant Deterioration, or NSR PSD, and Title V permitting programs. As a result, newly-issued NSR PSD or Title V permits for new or modified electricity
generating and other facilities may need to address GHG emissions, including by requiring the installation of Best Available Control Technology. Some of those regulations have been finalized and currently are in litigation. Courts have rejected
certain legal challenges to the endangerment finding, the tailoring rule, and other regulations but other legal challenges are pending. In addition, the EPA proposed in April 2012 a rule that would set a GHG emission standard applicable to new
electricity generating units, and the EPA re-proposed the rule in September 2013. The Obama Administration issued a plan in June 2013 under which the EPA is to issue a final rule by 2015 regulating GHG
emissions from existing electricity generating units. At the state level, California implemented a GHG cap-and-trade program that began imposing compliance obligations on industrial sectors, including electricity generators and importers, in January
2013. In addition, since 2005 the European Union (including the United Kingdom) has been operating under a cap-and-trade program, which directly affects the largest emitters of GHGs, including electricity producers from whom we purchase power.

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 Congress may pass, (ii) the regulations that the EPA has proposed or finalized, (iii) regulations under legislation that states have passed or may pass, or (iv) any
further reductions in the EU program could significantly increase our costs, and we may not be able to effectively pass all of these costs on to our tenants. These matters could adversely impact our business, results of operations, or financial
condition.

Interest rates. As of December 31, 2013, we had approximately $560.9 million of variable rate debt
subject to interest rate swap agreements on certain tranches of our unsecured term loan, along with $724.7 million and $460.0 million of variable rate debt that was outstanding on the global revolving credit facility and the unswapped portion of the
unsecured term loan, respectively. The availability of debt and equity capital may decrease as a result of the circumstances described above under Global market and economic conditions. The effects on commercial real estate mortgages, if
available, include, but may not be limited to: higher loan spreads, tightened loan covenants, reduced loan to value ratios resulting in lower borrower proceeds and higher principal payments. Potential future increases in interest rates and credit
spreads may increase our interest expense and fixed charges and negatively affect our financial condition and results of operations, potentially impacting our future access to the debt and equity capital markets. Increased interest rates may also
increase the risk that the counterparties to our swap agreements will default on their obligations, which could further increase our interest expense. If we cannot obtain capital from third party sources, we may not be able to acquire or develop
properties when strategic opportunities exist, satisfy our debt service obligations or pay the cash dividends to Digital Realty Trust, Inc.s stockholders necessary to maintain its qualification as a REIT.

Demand for datacenter space. Our portfolio of properties consists primarily of technology-related real estate and datacenter real
estate in particular. A decrease in the demand for, or increase in supply of, datacenter space, Internet gateway facilities or other technology-related real estate would have a greater adverse effect on our business and financial condition than if
we owned a portfolio with a more diversified tenant base or less specialized use. Over the past two years, we have made a significant investment in building out additional inventory primarily in what we anticipate will be our active major markets
prior to having executed leases with respect to this space. We believe that demand continues to exceed supply in most markets in which we operate, particularly in Northern Virginia, Dallas, Amsterdam and London, whereas we anticipate that our
Silicon Valley market may be at risk of significant over-supply. However, until this inventory is leased up, which will depend on a number of factors, including available datacenter space in these markets, our return on invested capital is
negatively impacted. Our development activities make us particularly susceptible to general economic slowdowns, including recessions and the other circumstances described above under Global market and economic conditions, as well as
adverse developments in the corporate datacenter, Internet and data communications and broader technology industries. Any such slowdown or adverse development could lead to reduced corporate IT spending or reduced demand for

datacenter space. Reduced demand could also result from business relocations, including to markets that we do not currently serve. Changes in industry practice or in technology, such as
virtualization technology, more efficient computing or networking devices, or devices that require higher power densities than todays devices, could also reduce demand for the physical datacenter space we provide or make the tenant
improvements in our facilities obsolete or in need of significant upgrades to remain viable. In addition, the development of new technologies, the adoption of new industry standards or other factors could render many of our tenants current
products and services obsolete or unmarketable and contribute to a downturn in their businesses, thereby increasing the likelihood that they default under their leases, become insolvent or file for bankruptcy. In addition, demand for datacenter
space in our properties, or the rates at which we lease space, may be adversely impacted either across our portfolio or in specific markets as a result of an increase in the number of competitors, or the amount of space being offered in our markets
and other markets by our competitors.

Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements,
which have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP. The preparation of these financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses in the reporting period. Our actual results may differ from these estimates. We have provided a summary of our significant accounting
policies in note 2 to our consolidated financial statements included elsewhere in this report. We describe below those accounting policies that require material subjective or complex judgments and that have the most significant impact on our
financial condition and consolidated results of operations. Our management evaluates these estimates on an ongoing basis, based upon information currently available and on various assumptions management believes are reasonable as of the date on the
front cover of this report.

Investments in Real Estate

Acquisition of real estate.The price that we pay to acquire a property is impacted by many factors including the condition of the
property and improvements, the occupancy of the building, the term and rate of in place leases, the creditworthiness of the tenants, favorable or unfavorable financing, above or below market ground leases and numerous other factors.

Accordingly, we are required to make subjective assessments to allocate the purchase price paid to acquire investments in real estate
among the identifiable assets including intangibles and liabilities assumed based on our estimate of the fair value of such assets and liabilities. This includes determining the value of the property and improvements, land, ground leases, if any,
and tenant improvements. Additionally, we evaluate the value of in-place leases on occupancy and market rent, the value of the tenant relationships, the value (or negative value) of above (or below) market leases, any debt or deferred taxes assumed
from the seller or loans made by the seller to us and any building leases assumed from the seller. Each of these estimates requires a great deal of judgment and some of the estimates involve complex calculations. These allocation assessments have a
direct impact on our results of operations. For example, if we were to allocate more value to land, there would be no depreciation with respect to such amount. If we were to allocate more value to the property as opposed to allocating to the value
of in-place tenant leases, this amount would be recognized as an expense over a much longer period of time. This potential effect occurs because the amounts allocated to property are depreciated over the estimated lives of the property whereas
amounts allocated to in-place tenant leases are amortized over the estimated term (including renewal and extension assumptions) of the leases. Additionally, the amortization of the value (or negative value) assigned to above (or below) market rate
leases is recorded as an adjustment to rental revenue as compared to amortization of the value of in-place tenant leases and tenant relationships, which is included in depreciation and amortization in our consolidated statements of operations.

Capitalization of Costs.Direct and indirect project costs that are clearly associated with the development of
properties are capitalized as incurred. Project costs include all costs directly associated with the development of a



63

##### Table of Contents

property, including construction costs, interest, property taxes, insurance, legal fees and costs of personnel working on the project. Indirect costs that do not clearly relate to the projects
under development are not capitalized and are charged to expense as incurred.

Capitalization of costs begins when activities,
including development of plans, process of obtaining permits from governmental authorities and physical construction that are necessary to get the asset ready for its intended use are in progress and costs have been incurred. Capitalization of costs
ceases when the development project is substantially complete and ready for its intended use. Determining when a development project commences, and when it is substantially complete and ready for its intended use involves a degree of judgment. We
generally consider a development project to be substantially complete and ready for its intended use upon receipt of a certificate of occupancy. We cease cost capitalization if activities necessary for the development of the property have been
suspended. Capitalized costs are allocated to the specific components of a project that are benefited.

During the second
quarter of 2013, in accordance with GAAP, we refined our capitalization practice related to operating expenditures which could have been capitalized, but had been expensed. Previously, operating expenditures totaling $10,000 or less that could have
been capitalized had been expensed as incurred for efficiency purposes. Under our refined capitalization practice, retrospective to January 1, 2013, such expenses are now capitalized. Additionally, we conformed the construction period
completion date, which is when capitalization of construction period operating costs ceases, with our construction period interest capitalization policy. Previously, capitalization of construction period operating costs ceased upon the commissioning
date. Retrospective to January 1, 2013, capitalization of construction period operating costs now ceases on receipt of the certificate of occupancy, among other factors. During the year ended December 31, 2013, the total incremental
amounts capitalized that would have been recorded as rental property operating expense under our previous policies was approximately $9.5 million.

Useful lives of assets.We are required to make subjective assessments as to the useful lives of our properties for purposes of determining the amount of depreciation to record on an annual basis
with respect to our investments in real estate. These assessments have a direct impact on our net income because if we were to shorten the expected useful lives of our investments in real estate we would depreciate such investments over fewer years,
resulting in more depreciation expense and lower net income on an annual basis.

Asset impairment evaluation.We review
each of our properties for indicators that its carrying amount may not be recoverable. Examples of such indicators may include a significant decrease in the market price of the property, a significant adverse change in the extent or manner in which
the property is being used in its physical condition or expected to be used based on the underwriting at the time of acquisition, an accumulation of costs significantly in excess of the amount originally expected for the acquisition or development
of the property, or a history of operating or cash flow losses of the property. When such impairment indicators exist, we review an estimate of the future undiscounted net cash flows (excluding interest charges) expected to result from the real
estate investments use and eventual disposition and compare that estimate to the carrying value of the property. We consider factors such as future operating income, trends and prospects, as well as the effects of leasing demand, competition
and other factors. If our future undiscounted net cash flow evaluation indicates that we are unable to recover the carrying value of a real estate investment, an impairment loss is recorded to the extent that the carrying value exceeds the estimated
fair value of the property. These losses have a direct impact on our net income because recording an impairment loss results in an immediate negative adjustment to net income. The evaluation of anticipated cash flows is highly subjective and is
based in part on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results in future periods. Since cash flows on properties considered to be long-lived assets to be held and used
are considered on an undiscounted basis to determine whether the carrying value of a property is recoverable, our strategy of holding properties over the long-term directly decreases the likelihood of their carrying values not being recoverable and
therefore requiring the recording of an impairment loss. If our strategy changes or market conditions otherwise dictate an earlier sale date, an impairment loss may be recognized and such loss could be material. If we determine that the asset fails
the recoverability test, the affected assets must be reduced to their fair value. No such impairment losses have been recognized to date.

We generally estimate the fair value of rental properties utilizing a discounted cash flow
analysis that includes projections of future revenues, expenses and capital improvement costs that a market participant would use based on the highest and best use of the asset, which is similar to the income approach that is commonly utilized by
appraisers.

Revenue Recognition

Rental revenue is recognized using the straight-line method over the terms of the tenant leases. Deferred rents
included in our consolidated balance sheets represent the aggregate excess of rental revenue recognized to date on a straight-line basis versus the contractual rental payments under the terms of the leases. Many of our leases contain provisions
under which the tenants reimburse us for a portion of property operating expenses and real estate taxes incurred by us. However, we generally 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. Such reimbursements are recognized in the period that the expenses are incurred. Lease termination fees
are recognized over the remaining term of the lease, effective as of the date the lease modification is finalized, assuming collection is not considered doubtful. As discussed above, we recognize amortization of the value of acquired above or below
market tenant leases as a reduction of rental revenue in the case of above market leases or an increase to rental revenue in the case of below market leases.

We must make subjective estimates as to when our revenue is earned and the collectability of our accounts receivable related to minimum rent, deferred rent, expense reimbursements, lease termination fees
and other income. We specifically analyze accounts receivable and historical bad debts, tenant concentrations, tenant creditworthiness and current economic trends when evaluating the adequacy of the allowance for bad debts. These estimates have a
direct impact on our net income because a higher bad debt allowance would result in lower net income, and recognizing rental revenue as earned in one period versus another would result in higher or lower net income for a particular period.

Share-Based Awards

We recognize compensation expense related to share-based awards. We generally amortize this compensation expense over the vesting period of the award. The calculation of the fair value of share-based
awards is subjective and requires several assumptions over such items as expected stock volatility, dividend payments and future company results. These assumptions have a direct impact on our net income because a higher share-based awards amount
would result in lower net income for a particular period.

Results of Operations

The discussion below relates to our financial condition and results of operations for the years ended December 31, 2013, 2012 and
2011. A summary of our operating results from continuing operations for the years ended December 31, 2013, 2012 and 2011 was as follows (in thousands).

Portfolio

As of December 31, 2013, our portfolio consisted of 131
properties, including 12 properties held as investments in unconsolidated joint ventures and developable land, with an aggregate of 24.5 million rentable square feet including 1.8 million square feet of space under active development and
1.3 million square feet of space held for future development compared to a portfolio consisting of 124 properties, including three properties held as investments in unconsolidated joint ventures and developable land, with an aggregate of
23.3 million rentable square feet including 1.4 million square feet of space under active development and 2.0 million square feet of space held for future development as of December 31, 2012 and a portfolio consisting of 109
properties, including three properties held as investments in unconsolidated joint ventures and developable land, with an aggregate of 18.7 million rentable square feet including 1.2 million square feet of space under active development
and 1.6 million square feet of space held for future development as of December 31, 2011. The increase in our portfolio reflects the acquisition of 10 properties in 2011 (in addition, two properties were placed into service in 2011 in which the
land parcel was acquired prior to January 1, 2011), 15 properties in 2012 (in addition, three properties were placed into service in 2012 in which the land parcel was acquired prior to January 1, 2012) and 7 properties in 2013 (in addition, one

##### Table of Contents

As shown by the same store and new properties table below, the increases in rental
revenues and tenant reimbursement revenues in the year ended December 31, 2013 compared to 2012 were due to new leasing at our same store properties, including completed and leased development space, and acquisitions of properties. Other
revenues changes in the periods presented were primarily due to tenant termination revenues. We acquired 7, 15 and 10 properties during the years ended December 31, 2013, 2012 and 2011, respectively.

Same store rental revenues increased for the year ended December 31, 2013 compared to the same
period in 2012 primarily as a result of new leases at our properties during 2013, including leases of completed development space, the largest of which were for space in 29A International Business Park, 43940 Digital Loudoun Plaza, 98 Radnor Drive
and 3825 NW Aloclek Place. Same store growth was driven by the delivery of approximately 585,000 square feet of leased data center space from within our same store development platform during the last 12 months. In our same store portfolio, we
calculate the change in rental rates on renewals signed during the quarter as compared to the previous rent on that same space. During the twelve months ended December 31, 2013, the percentage increase was 17.6% on a GAAP basis. Same store
rental revenues increased for the year ended December 31, 2013 as compared to the same period in 2012 as a result of the increase in rentable square feet of leased data center space. During the twelve months ended December 31, 2013, we
also delivered approximately 119,000 square feet of un-leased data center space which was one of the drivers impacting occupancy which decreased slightly to 91.2% as of December 31, 2013 from 93.3% as of December 31, 2012 along with
certain leases expiring at one of our non-technical properties during 2013. Rental revenue included amounts earned from leases with The tel(x) Group, Inc., or tel(x), which was sold to an unrelated third party in 2011, of approximately $48.6 million
and $45.7 million for the year ended December 31, 2013 and 2012, respectively. Same store tenant reimbursement revenues increased for the year ended December 31, 2013 as compared to the same period in 2012 primarily as a result of new
leasing and higher utility and operating expenses being billed to our tenants, the largest occurrences of which were at 29A International Business Park, 365 South Randolphville Road and 350 East Cermak Road.

New properties revenue increases were due to the addition of properties acquired during the period from January 1, 2012 to
December 31, 2012. For the year ended December 31, 2013, the Sentrum Portfolio, the Paris Portfolio and 400 S. Akard contributed $90.7 million, or approximately 83%, of the new properties increase in rental revenues and tenant
reimbursements compared to the same period in 2012.

Same store rental revenues increased for the year ended December 31, 2012 compared to the same
period in 2011 primarily as a result of new leases at our properties during 2012 due to strong demand for datacenter space, including leases of completed development space, the largest of which was for space in 29A International

Business Park, 4030-4050 Lafayette and 4849 Alpha Road. Rental revenue included amounts earned from leases with tel(x) of approximately $45.7 million and $42.5 million for the year ended
December 31, 2012 and 2011, respectively. Same store tenant reimbursement revenues increased for the year ended December 31, 2012 as compared to the same period in 2011 primarily as a result of new leasing and higher utility and operating
expenses being billed to our tenants, the largest occurrences of which were at 29A International Business Park, 350 East Cermak Road, 1100 Space Park Drive and Paul van Vlissingenstraat 16.

New properties revenue increases were due to the addition of properties acquired during the period from January 1, 2011 to
December 31, 2012. For the year ended December 31, 2012, the Sentrum Portfolio, Convergence Business Park, 760 Doug Davis Drive and 360 Spear Street contributed $109.3 million, or approximately 86%, of the new properties increase in rental
revenues and tenant reimbursements compared to the same period in 2011. Fee income was significantly higher in 2011 due to a contract in which the majority of the work was performed in 2011. The contract was completed in early 2012.

As shown in the same store and new properties table below, total expenses for the year ended
December 31, 2013 increased compared to the same period in 2012 primarily as a result of higher utility rates in several of our properties along with development projects being placed into service leading to higher utility expense (included in
rental property operating and maintenance) in 2013. The following table shows expenses for new properties (properties that were acquired after December 31, 2011) and same store properties (all other properties) (in thousands).

Same store rental property operating and maintenance expenses increased in the year ended December 31, 2013 compared to the same
period in 2012 primarily as a result of higher consumption and utility rates in several of our properties along with development projects being placed into service leading to higher utility expense in 2013. In 2013, a non-cash $10.0 million
straight-line rent expense adjustment was recorded in rental property operating and maintenance expenses related to a lease amendment executed in September 2010, $7.5 million of this amount related to prior years. This adjustment was deemed to be
immaterial to both the current year and prior year financial statements taken as a whole.

Same store property taxes increased
by approximately $14.9 million in the year ended December 31, 2013 compared to the same period in 2012, primarily as a result of additional property tax assessments in our Santa Clara, California and Texas properties.

Same store depreciation and amortization expense increased in the year ended December 31, 2013 compared to the same period in 2012,
principally because of depreciation of development projects that were placed into service in late 2012 and during 2013.

General and administrative expenses for the year ended December 31, 2013 increased compared to the same period in 2013 primarily due
to the growth of our company, which resulted in more employees, additional incentive compensation, and higher professional fees and marketing expenses.

Same store interest expense increased for the year ended December 31, 2013 as compared to the same period in 2012 primarily as a result of higher average balances on our unsecured term loan
(originally closed in April 2012), offset by lower average outstanding mortgage debt balances during 2013 compared to 2012 primarily due to the paydown of the following loans: 114 Rue Ambroise Croizat (January 2012), Unit 9, Blanchardstown Corporate
Park (January 2012), 1201 Comstock Street (April 2012), 2805 Lafayette Street (May 2012), 2805 Lafayette Street Mezzanine (May 2012), 1350 Duane Avenue/3080 Raymond Street (September 2012), Clonshaugh Industrial Estate II (June 2013), 1500 Space
Park Drive (July 2013), Paul van Vlissingenstraat 16 (July 2013), Chemin de lEpinglier 2 (July 2013), Mundells Roundabout (October 2013), Gyroscoopweg 2E-2F (October 2013) and 360 Spear Street (November
2013). During the years ended December 31, 2013 and 2012, we capitalized interest of approximately $26.3 million and $21.5 million, respectively.

New properties increases were caused by properties acquired during the period from January 1, 2012 to December 31, 2013. For the year ended December 31, 2013, the Sentrum Portfolio, 9333,
9355, 9377 Grand Avenue and 400 S. Akard contributed $56.3 million, or approximately 84%, of the total new properties increase in total operating expenses (excluding construction management) compared to the same period in 2012.

Same store rental property operating and maintenance expenses increased in the year ended December 31, 2012 compared to the same
period in 2011 primarily as a result of higher consumption and utility rates in several of our properties along with development projects being placed into service leading to higher utility expense in 2012. We capitalized amounts relating to
compensation expense of employees direct and incremental to construction and executed leasing activities of $31.6 million and $24.7 million for the years ended December 31, 2012 and 2011, respectively.

Same store depreciation and amortization expense increased in the year ended December 31, 2012 compared to the same period in 2011,
principally because of depreciation of development projects that were placed into service in late 2011 and during 2012.

General and administrative expenses for the year ended December 31, 2012 increased compared to the same period in 2011 primarily due
to the growth of our company, which resulted in more employees, additional incentive compensation, and higher professional fees and marketing expenses.

Same store interest expense decreased for the year ended December 31, 2012 as compared to the same period in 2011 primarily as a result of lower average outstanding mortgage debt balances during 2012
compared to 2011 primarily due to the paydown of the following loans: 114 Rue Ambroise Croizat (January 2012), Unit 9, Blanchardstown Corporate Park (January 2012), 1201 Comstock Street (April 2012), 2805 Lafayette Street (May 2012), 2805 Lafayette
Street Mezzanine (May 2012) and 1350 Duane Avenue/3080 Raymond Street (September 2012). This decrease was partially offset by the issuance of our 3.625% Notes due 2022 (2022 Notes) in September 2012. During the years ended December 31, 2012 and
2011, we capitalized interest of approximately $21.5 million and $17.9 million, respectively.

New properties increases were
caused by properties acquired during the period from January 1, 2011 to December 31, 2012. For the year ended December 31, 2012, the Sentrum Portfolio, Convergence Business Park

and 760 Doug Davis Drive contributed $67.1 million, or approximately 74%, of the total new properties increase in total operating expenses (excluding construction management) compared to the same
period in 2011. Construction management expense was significantly higher in 2011 due to a contract in which the majority of the work was performed in 2011. The contract was completed in early 2012.

Transactions expense increased in the year ended December 31, 2012 compared to the same period in 2011, principally because of
expenses related to the acquisitions of the Sentrum Portfolio and Paris Portfolio in 2012.

Liquidity and Capital Resources of the Parent
Company

In this Liquidity and Capital Resources of the Parent Company section and in the Liquidity and
Capital Resources of the Operating Partnership section below, the term, our parent company, refers to Digital Realty Trust, Inc. on an unconsolidated basis, excluding our operating partnership.

Analysis of Liquidity and Capital Resources

Our parent companys business is operated primarily through our operating partnership of which our parent company is the sole general partner and which it consolidates for financial reporting
purposes. Because our parent company operates on a consolidated basis with our operating partnership, the section entitled Liquidity and Capital Resources of the Operating Partnership should be read in conjunction with this section to
understand the liquidity and capital resources of our parent company on a consolidated basis and how our company is operated as a whole.

Our parent company issues public equity from time to time, but does not otherwise generate any capital itself or conduct any business itself, other than incurring certain expenses in operating as a public
company which are fully reimbursed by the operating partnership. Our parent company itself does not hold any indebtedness other than guarantees of the indebtedness of our operating partnership and certain of its subsidiaries, and its only material
asset is its ownership of partnership interests of our operating partnership. Therefore, the consolidated assets and liabilities and the consolidated revenues and expenses of our parent company and our operating partnership are the same on their
respective financial statements, except for immaterial differences related to cash, other assets and accrued liabilities that arise from public company expenses paid by our parent company. However, all debt is held directly or indirectly at the
operating partnership level. Our parent companys principal funding requirement is the payment of dividends on its common and preferred shares. Our parent companys principal source of funding for its dividend payments is distributions it
receives from our operating partnership.

As the sole general partner of our operating partnership, our parent company has the
full, exclusive and complete responsibility for our operating partnerships day-to-day management and control. Our parent company causes our operating partnership to distribute such portion of its available cash as our parent company may in its
discretion determine, in the manner provided in our operating partnerships partnership agreement. Our parent company receives proceeds from its equity issuances from time to time, but is generally required by our operating partnerships
partnership agreement to contribute the proceeds from its equity issuances to our operating partnership in exchange for partnership units of our operating partnership.

Our parent company is a well-known seasoned issuer with an effective shelf registration statement filed on April 23, 2012 that allows our parent company to register unspecified various classes of
equity securities. As circumstances warrant, our parent company 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 be generally
contributed to our operating partnership in exchange for additional equity interests in our operating partnership. Our operating partnership may use the proceeds to acquire additional properties, to fund development opportunities and for general
working capital purposes, including potentially for the repurchase, redemption or retirement of outstanding debt or preferred securities.

##### Table of Contents

The liquidity of our parent company is dependent on our operating partnerships ability
to make sufficient distributions to our parent company. The primary cash requirement of our parent company is its payment of dividends to its stockholders. Our parent company also guarantees our operating partnerships, as well as certain of
its subsidiaries unsecured debt. If our operating partnership or such subsidiaries fail to fulfill their debt requirements, which trigger parent company guarantee obligations, then our parent company will be required to fulfill its cash
payment commitments under such guarantees. However, our parent companys only asset is its investment in our operating partnership.

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 company and, in turn, for our parent company 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 its ability to make distribution payments to our parent company. The lack of availability of capital could adversely affect our operating partnerships ability to pay its
distributions to our parent company, which would in turn, adversely affect our parent companys ability to pay cash dividends to its stockholders.

On June 29, 2011, our parent company commenced an At-the-Market equity distribution program under which it can issue and sell up to $400.0 million of its common stock through, at its discretion, any
of Merrill Lynch, Pierce Fenner & Smith Incorporated, Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC, Deutsche Bank Securities Inc. and Morgan Stanley & Co. LLC as its sales agents. For the year ended
December 31, 2012, our parent company generated net proceeds of approximately $62.7 million from the issuance of approximately 1.0 million shares of common stock under the program at an average price of $66.19 per share after payment of
approximately $0.6 million of commissions to the sales agents. The proceeds from the issuances were contributed to our operating partnership in exchange for the issuance of approximately 1.0 million common units to our parent company. No sales
were made under the program during the year ended December 31, 2013. The sales of common stock under the equity distribution program will be made in at the market offerings as defined in Rule 415 of the Securities Act. As of
December 31, 2013, shares of common stock having an aggregate offering price of $53.8 million remained available for offer and sale under the program.

On January 18, 2013, Digital Stout Holding, LLC, a wholly-owned subsidiary of Digital Realty Trust, L.P., issued £400.0 million (or approximately $634.8 million based on the exchange rate
of £1.00 to $1.59 on January 18, 2013) aggregate principal amount of its 4.250% Guaranteed Notes due 2025, or the 2025 notes. The 2025 Notes are senior unsecured obligations of Digital Stout Holding, LLC and are fully and unconditionally
guaranteed by the parent company and our operating partnership. Interest on the 2025 notes is payable semiannually in arrears at a rate of 4.250% per annum. The net proceeds from the offering after deducting the original issue discount of
approximately $4.8 million and underwriting commissions and estimated expenses of approximately $5.8 million was approximately $624.2 million. We used the net proceeds from this offering to temporarily repay borrowings under our global revolving
credit facility.

Effective February 26, 2013, our parent company converted all outstanding shares of its series D
preferred stock into shares of our parent companys common stock in accordance with the terms of the series D preferred stock. Each share of series D preferred stock was converted into 0.6360 share of our parent companys common stock. In
connection with this conversion, our operating partnership issued 3,054,186 common units to our parent company upon conversion of 4,802,180 series D cumulative convertible preferred units. During the years ended December 31, 2013 and 2012, our
operating partnership issued 3,139,615 and 1,297,675 common units, respectively, to our parent company upon conversion of 4,936,505 and 2,040,550 series D cumulative convertible preferred units.

On April 9, 2013, our parent company issued an aggregate of 10.0 million shares of its 5.875% series G cumulative redeemable
preferred stock for total net proceeds, after underwriting discounts and estimated offering

expenses, of $241.5 million, including the proceeds from the partial exercise of the underwriters over-allotment option. We used the net proceeds from the offering to temporarily repay
borrowings under our global revolving credit facility.

On October 23, 2013, our parent companys board of directors
authorized a share repurchase program under which our parent company may repurchase up to $500.0 million of its outstanding common stock, which our parent company may use to opportunistically reacquire shares on the open market or in privately
negotiated transactions or otherwise, based on the then-current share price and capital allocation alternatives. No repurchases were made under the program during the year ended December 31, 2013.

Future Uses of Cash

Our parent company may from time to time seek to retire, redeem or repurchase its preferred equity or the debt securities of our operating partnership 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.

We are also subject to the commitments discussed below under Dividends
and Distributions.

Dividends and Distributions

Our parent company is required to distribute 90% of its taxable income (excluding capital gains) on an annual basis in order for it to
continue to qualify as a REIT for federal income tax purposes. Accordingly, our parent company intends to make, but is not contractually bound to make, regular quarterly distributions to its common stockholders from cash flow from our operating
partnerships operating activities. While historically our parent company 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 companys board of directors. Our parent company considers market factors and our operating partnerships performance in addition to REIT requirements in
determining distribution levels. Our parent company has distributed at least 100% of its taxable income annually since inception to minimize corporate level federal 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 companys status as a REIT. The exchange rate on the operating partnerships 5.50%
exchangeable senior debentures due 2029 (2029 Debentures) is subject to adjustment for certain events, including, but not limited to, certain dividends on our parent companys common stock in excess of $0.33 per share per quarter. Therefore,
the declaration and payment of quarterly dividends by our parent company in excess of this threshold may increase the dilutive impact of the 2029 Debentures on our parent companys common stockholders.

As a result of this distribution requirement, our operating partnership cannot rely on retained earnings to fund its on-going operations
to the same extent that other companies whose parent companies are not REITs can. Our parent company 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 company may be required to use borrowings under our operating partnerships global revolving
credit facility, if necessary, to meet REIT distribution requirements and maintain our parent companys REIT status.

Distributions out of our parent companys current or accumulated earnings and profits are generally classified as ordinary income
whereas distributions in excess of our companys current and accumulated earnings and profits, to the extent of a stockholders U.S. federal income tax basis in our parent company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 company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.

The expected tax treatment of distributions paid on our parent companys common and preferred stock paid in 2013 is as follows: approximately 75% ordinary income and 25% capital gain distribution.
The tax treatment of distributions paid on our parent companys common stock paid in 2012 was as follows: approximately 91% ordinary income, 8% return of capital and 1% capital gain distribution. The tax treatment of distributions paid on our
parent companys preferred stock paid in 2012 was as follows: approximately 99% ordinary income and 1% capital gain distribution. All distributions paid on our parent companys common and preferred stock in 2011 were classified as ordinary
income for income tax purposes.

Liquidity and Capital Resources of the Operating Partnership

In this Liquidity and Capital Resources of the Operating Partnership section, the terms we, our and
us refer to our operating partnership together with its consolidated subsidiaries or our operating partnership and our parent company together with their consolidated subsidiaries, as the context requires.

Analysis of Liquidity and Capital Resources

Our parent company is our sole general partner and consolidates our results of operations for financial reporting purposes. Because we operate on a consolidated basis with our parent company, the section
entitled Liquidity and Capital Resources of the Parent Company should be read in conjunction with this section to understand our liquidity and capital resources on a consolidated basis.

As of December 31, 2013, we had $56.8 million of cash and cash equivalents, excluding $40.4 million of restricted cash.
Restricted cash primarily consists of interest-bearing cash deposits required by the terms of several of our mortgage loans for a variety of purposes, including real estate taxes, insurance, anticipated or contractually obligated tenant
improvements, as well as capital expenditures.

Our short-term liquidity requirements primarily consist of operating expenses,
development costs and other expenditures associated with our properties, distributions to our parent company in order for it to make dividend payments on its preferred stock, distributions to our parent company in order for it to make dividend
payments to its stockholders required to maintain its REIT status, distributions to the unitholders in our operating partnership, capital expenditures, debt service on our loans and, potentially, acquisitions. We expect to meet our short-term
liquidity requirements through net cash provided by operations, restricted cash accounts established for certain future payments and by drawing upon our global revolving credit facility.

On August 15, 2013, we refinanced our revolving credit facility, which we refer to as the global revolving credit facility,
increasing its total borrowing capacity to $2.0 billion from $1.8 billion. The global revolving credit facility has an accordion feature that would enable us to increase the borrowing capacity of the credit facility to $2.55 billion, subject to the
receipt of lender commitments and other conditions precedent. The refinanced facility matures on November 3, 2017, with two six-month extension options. The interest rate for borrowings under the expanded facility equals the applicable index
plus a margin which is based on the credit rating of our long-term debt and is currently 110 basis points. An annual facility fee on the total commitment

amount of the facility, based on the credit rating of our long-term debt and currently 20 basis points, is payable quarterly. Funds may be drawn in U.S., Canadian, Singapore, Australian and Hong
Kong dollars, as well as Euro, British pound sterling, Swiss franc, Japanese yen and Mexican peso denominations. As of December 31, 2013, borrowings under the global revolving credit facility bore interest at an overall blended rate of 1.60%
comprised of 1.27% (U.S. dollars), 1.33% (Euros), 3.70% (Australian dollars), 1.31% (Hong Kong dollars), 1.21% (Japanese yen) and 2.32% (Canadian dollars). The interest rates are based on 1-month LIBOR, 1-month GBP LIBOR, 1-month EURIBOR, 1-month
BBR, 1-month HIBOR, 1-month JPY LIBOR and 1-month CDOR, respectively, plus a margin of 1.10%. The facility also bore a base borrowing rate of 3.35% (USD) which is based on U.S. Prime Rate plus a margin of 0.10%. We have used and intend to use
available borrowings under the global revolving credit facility to acquire additional properties, fund development opportunities and to provide for working capital and other corporate purposes, including potentially for the repurchase, redemption or
retirement of outstanding debt or preferred equity securities. As of December 31, 2013, we have capitalized approximately $17.9 million of financing costs related to the global revolving credit facility. As of December 31, 2013,
approximately $724.7 million was drawn under this facility and $20.6 million of letters of credit were issued, leaving approximately $1.3 billion available for use.

On August 15, 2013, we refinanced the senior unsecured multi-currency term loan facility, increasing its total borrowing capacity to $1.0 billion from $750.0 million, and pursuant to the accordion
feature total commitments can be increased up to $1.1 billion, subject to the receipt of lender commitments and other conditions precedent. The facility matures on April 16, 2017, with two six-month extension options. Interest rates are based
on our senior unsecured debt ratings and are currently 120 basis points over the applicable index for floating rate advances. Funds may be drawn in U.S, Singapore and Australian dollars, as well as Euro and British pound sterling denominations with
the option to add Hong Kong dollars and Japanese yen upon an accordion exercise. Based on exchange rates in effect at December 31, 2013, the balance outstanding is approximately $1,021.0 million. We have used borrowings under the term loan for
acquisitions, repayment of indebtedness, development, working capital and general corporate purposes. As of December 31, 2013, we have capitalized approximately $8.4 million of financing costs related to the unsecured term loan.

For a discussion of the potential impact of current global economic and market conditions on our liquidity and capital resources, see
Factors Which May Influence Future Results of OperationsGlobal market and economic conditions above.

On June 29, 2011, our parent company commenced its new At-the-Market equity distribution program discussed under Liquidity and
Capital Resources of the Parent Company above. For the year ended December 31, 2012, our parent company generated net proceeds of approximately $62.7 million from the issuance of approximately 1.0 million shares of common stock under
the program at an average price of $66.19 per share after payment of approximately $0.6 million of commissions to the sales agents. The proceeds from the issuances were contributed to us in exchange for the issuance of approximately
1.0 million common units to our parent company. No sales were made under the program during the year ended December 31, 2013. As of December 31, 2013, shares of common stock having an aggregate offering price of $53.8 million remained
available for offer and sale under the program.

On January 18, 2013, Digital Stout Holding, LLC, our wholly-owned
subsidiary, issued £400.0 million (or approximately $634.8 million based on the exchange rate of £1.00 to $1.59 on January 18, 2013) aggregate principal amount of its 4.250% Guaranteed Notes due 2025, or the 2025 notes. The
2025 Notes are senior unsecured obligations of Digital Stout Holding, LLC and are fully and unconditionally guaranteed by our parent company and us. Interest on the 2025 notes is payable semiannually in arrears at a rate of 4.250% per annum.
The net proceeds from the offering after deducting the original issue discount of approximately $4.8 million and underwriting commissions and estimated expenses of approximately $5.8 million was approximately $624.2 million. We used the net proceeds
from this offering to temporarily repay borrowings under our global revolving credit facility.

On January 31, 2013, we completed the acquisition of two properties for an aggregate
purchase price of $32.5 million. One property is a 61,750 square foot data center and is located in the Dallas metropolitan area. The other property consists of three buildings totaling approximately 227,000 square feet and is located in the Phoenix
metropolitan area. Two of the buildings are non-technical single tenant sale-leasebacks and the third building will be developed. The acquisitions were financed with borrowings under our global revolving credit facility.

On March 11, 2013, we made an initial investment of $12.5 million in a data center, network and IT services company in Mexico. This
investment represents our entrance into the Mexican market. An additional investment of approximately $4.7 million was made in April 2013. The investments were financed with borrowings under our global revolving credit facility.

On March 12, 2013, we completed the acquisition of a 120,000 square foot data center development property for approximately $8.4
million. The property is located in the Toronto metropolitan area. The acquisition was financed with borrowings under our global revolving credit facility.

On March 27, 2013, we completed the acquisition of a 329,000 square foot data center for $37.0 million. The property is located in the Minneapolis metropolitan area and is structured as a
sale-leaseback transaction. The acquisition was financed with borrowings under our global revolving credit facility.

On
April 2, 2013, we acquired a three-acre land site in London for a previously signed Custom Solutions agreement for a purchase price of $3.6 million. The acquisition was financed with borrowings under our global revolving credit facility.

On May 20, 2013, we completed the acquisition of a six-building portfolio consisting of operating data centers and flex
office space totaling approximately 337,000 square feet for $31.9 million. The property is located in the Austin metropolitan area. The acquisition was financed with borrowings under our global revolving credit facility.

On June 27, 2013, we completed a sale-leaseback transaction for a partially-built data center in Groningen, Netherlands for a
purchase price of $3.9 million. We paid an additional $2.6 million in October 2013 upon completion of construction by the tenant, with the final payment of $1.4 million made in December 2013. This initial development totaled approximately 16,800
square feet of space. The acquisition was financed with borrowings under our global revolving credit facility.

On
August 9, 2013, we acquired a 3.7 acre land site in Osaka, Japan for a purchase price of $9.6 million. The acquisition was financed with borrowings under our global revolving credit facility.

On September 23, 2013, we acquired an 11.8 acre land site in London for a previously signed Custom Solutions agreement for a
purchase price of $19.3 million. The acquisition was financed with borrowings under our global revolving credit facility.

On
September 24, 2013, we acquired a 5.4 acre land site in Amsterdam for a purchase price of $6.7 million. The acquisition was financed with borrowings under our global revolving credit facility.

On December 19, 2013, we completed the acquisition of a 108,000 square foot data center in Somerset, New Jersey (New York
Metro) for approximately $35.3 million. The purchase price includes the assumption of a $26.4 million mortgage loan. The acquisition was financed with borrowings under our global revolving credit facility.

Purchase prices are all in U.S. dollars and exclude capitalized closing costs on land acquisitions. Purchase prices for acquisitions
outside the United States are based on the exchange rate at the date of acquisition.

The weighted average cash capitalization rate on income-producing properties, excluding
development projects, acquired during the year ended December 31, 2013 was 9.7%. We calculate the cash capitalization rate on acquisitions by dividing anticipated annual net operating income by the purchase price (including assumed debt). Net
operating income represents rental revenue and tenant reimbursement revenue from in place leases less rental property operating and maintenance expenses, property taxes and insurance expenses and is not a financial measure calculated in accordance
with GAAP. Our calculation of the weighted average cash capitalization rate for acquisitions may change based on our experience operating the properties following the closing of the acquisitions. The growing acceptance by private institutional
investors of the data center asset class has generally pushed capitalization rates lower, as such private investors typically have lower return expectations than us. As a result, we anticipate that near-term acquisitions activity will comprise a
smaller percentage of our growth until seller price expectations realign with our return requirements.

On September 27, 2013, we formed a joint venture with an investment fund managed by Prudential Real Estate
Investors (PREI®). We contributed nine Powered Base Building® data centers totaling 1.06 million square feet and valued at approximately $366.4 million (excluding $2.8 million of closing costs). The PREI®-managed fund took an 80% interest in the joint venture and we retained a 20% interest. The joint venture is
structured to provide a current annual preferred return from cash flow first to the PREI®-managed interest, then
to our interest, after which a portion of any excess cash flows is shared by the partners based on their respective interests and the remaining portion is paid to us as a promoted interest. We perform the day-to-day accounting and property
management functions for the joint venture and, as such, will earn a management fee for the services provided. Although we are the managing member of the joint venture and manage the day-to-day activities, all significant decisions, including
approval of annual budgets and setting the amount of our management fees require approval of the PREI® member.
Thus we concluded we do not own a controlling interest and will account for our interest in the joint venture as an equity method investment.

Land Inventory and Space Held for Development reflect cumulative cost on space
pending future development. Base building construction consists of ongoing improvements to building infrastructure in preparation for future datacenter fit-out. Product under construction includes 697,034 square feet of Turn Key Flex® Powered Base Building®, and Custom Solutions product with a cost to date of approximately $269.7 million. Generally, 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 datacenter construction fit-out. Campus,
Tenant Improvements and Other costs include the value of development work associated with space included in our Occupancy Analysis as either occupied or vacant.

In May 2013, we received insurance settlement proceeds of approximately $8.6 million related
to disputed construction costs, a portion of which has been recorded as a gain on settlement in our consolidated income statement included elsewhere in this report.

Future Uses of Cash

Our properties require periodic
investments of capital for tenant-related capital expenditures and for general capital improvements. As of December 31, 2013, we had approximately 1.8 million square feet of space under active development and approximately 1.3 million
square feet of space held for future development, and we also owned approximately 678,000 net rentable square feet of datacenter space with extensive installed tenant improvements. Turn-Key
FlexSMspace is move-in-ready space for the placement of
computer and network equipment required to provide a datacenter environment. Depending on demand for additional Turn-Key Flex space, we expect to incur significant tenant improvement costs to build out and develop these types of spaces. At
December 31, 2013, approximately 1,760,000 square feet was under construction for Turn-Key Flex, Powered Base
Building® and Custom Solutions product, all of which are expected to be income producing on or after completion,
in eight U.S. domestic markets, three European markets, one Canadian market and one Australian market, consisting of approximately 1,063,000 square feet of base building construction and 697,000 square feet of data center construction. At
December 31, 2013, we had commitments under construction contracts for approximately $202.1 million. We currently expect to incur approximately $600.0 million to $800.0 million of capital expenditures for our development programs
during the year ending December 31, 2014, although this amount may increase or decrease, potentially materially, based on numerous factors, including changes in demand, leasing results and availability of debt or equity capital.

For the year ended December 31, 2013, total capital expenditures increased $302.5 million to
approximately $1.1 billion from the year ended December 31, 2012. Capital expenditures on our development projects plus our enhancement and improvements projects for the year ended December 31, 2013 were approximately $1.0 billion, which
reflects an increase of approximately 39% from the same period in 2012. This increase was primarily due to increased spending for ground-up Custom Solutions projects, Turn-Key Flex and base building improvements. Our development capital expenditures
are generally funded by our available cash and equity and debt capital.

Indirect costs, including capitalized interest,
capitalized in the years ended December 31, 2013 and 2012 were $64.7 million and $53.7 million, respectively. Capitalized interest comprised approximately $26.3 million and $21.5 million, respectively, of the total indirect costs capitalized for the
years ended December 31, 2013 and 2012. Capitalized interest in the year ended December 31, 2013 increased compared to the same period in 2012 due to an increase in the value of qualifying activities in progress during the year ended December 31,
2013 as compared to the year ended December 31, 2012. Excluding capitalized interest, the increase in indirect costs in the year ended December 31, 2013 compared to the same period in 2012 was primarily due to capitalized amounts relating to
compensation expense of employees directly engaged in construction and leasing activities. See Future Uses of Cash for a discussion of the amount of capital expenditures we expect to incur during the year ending December 31, 2014.

##### Table of Contents

We are in the process of analyzing the extent of the environmental cleanup work required at
the 47700 Kato Road and 1055 Page Avenue property. We intend to seek recovery of costs related to this work from a prior tenant of the building and/or performance by the prior tenant of the required work. We cannot at this time estimate the
magnitude of these costs, the likelihood of recovery or the impact on our financial condition and results of operations, however, the amounts are not expected to be material.

We are also subject to the commitments discussed below under Commitments and Contingencies, Off-Balance Sheet Arrangements and Distributions.

Consistent with our growth strategy, we actively pursue opportunities for potential acquisitions, with due diligence and negotiations
often at different stages at different times. The dollar value of acquisitions for the year ending December 31, 2014 will be based on numerous factors, including tenant demand, leasing results, availability of debt or equity capital and
acquisition opportunities.

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

We expect to meet our short- and long-term liquidity requirements, including to pay for scheduled debt maturities and to fund property
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 company. We
also may fund future short- and long-term liquidity requirements, including property acquisitions and non-recurring capital improvements using our global revolving credit facility pending permanent financing. If we are not able to obtain additional
financing on terms attractive to us, or at all, including as a result of the circumstances described above under Factors Which May Influence Future Results of OperationsGlobal market and economic conditions, we may be required to
reduce our acquisition or capital expenditure plans, which could have a material adverse effect upon our business and results of operations.

Commitments and Contingencies

As part of the acquisition of 29A International Business Park, the seller could earn additional consideration based on future net operating income growth in excess of certain performance targets, as
defined. As of December 31, 2013, construction is not complete and none of the leases executed subsequent to purchase would cause an amount to become probable of payment and therefore no amount is accrued as of December 31, 2013. The
maximum amount that could be earned by the seller is $50.0 million SGD (or approximately $39.6 million based on the exchange rate as of December 31, 2013). The earnout contingency expires in November 2020.

One of the tenants at our Convergence Business Park property has an option to expand as part of their lease agreement, which expires in
April 2017. As part of this option, development activities are not permitted on specifically identified expansion space within the property until April 2014. If the tenant elects to take this option, we can elect one of two
options. The first option is to construct and develop an additional shell building on the expansion space. Concurrent with this obligation, the tenant would execute an amendment to the existing lease to reflect the expansion of the space
and include the additional shell building. The second option is to sell the existing building and the expansion space to the tenant for a price of approximately $24.0 million and $225,000 per square acre, respectively, plus additional adjustments as
provided in the lease.

As part of the acquisition of the Sentrum Portfolio, the seller could earn additional consideration
based on future net returns on vacant space to be developed, but not currently leased, as defined in the purchase agreement for the acquisition. The initial estimate of fair value of contingent consideration was approximately
£56.5 million (or approximately $87.6 million based on the exchange rate as of July 11, 2012, the acquisition date). In 2013, we made certain immaterial corrections to the initial measurement of the accrued contingent consideration
that resulted in an additional $5.8 million of purchase price allocated to investments in real estate. These corrections had no impact on reported net income for the period. We have adjusted the contingent consideration to fair value at each
reporting date with changes in fair value recognized in operating income. At December 31, 2013, the fair value of the contingent consideration for Sentrum was £39.2 million (or approximately $64.9 million based on the exchange rate
as of December 31, 2013) and is currently accrued in accounts payable and other accrued expenses in the consolidated balance sheet. During the year ended December 31, 2013, we have made earnout payments of approximately
£16.9 million (or approximately $25.8 million based on the exchange rates as of the date of each payment). Change in fair value of contingent consideration for Sentrum was an increase to operating income of approximately $1.8 million and
$1.1 million for the years ended December 31, 2013 and 2012, respectively. The earn-out contingency expires in July 2015. This amount will be reassessed on a quarterly basis, with any changes being recognized in earnings. Increases or decreases
in the fair value of the contingent consideration can result from changes in discount periods, discount rates and probabilities that contingencies will be met.

As of December 31, 2013, we were a party to interest rate swap agreements which hedge variability in cash flows related the U.S. LIBOR and SGD-SOR based tranches of the unsecured term loan. Under
these swaps, we pay variable-rate amounts in exchange for fixed-rate payments over the life of the agreements without exchange of the underlying principal amounts. See Item 7A Quantitative and Qualitative Disclosures about Market
Risk.

41% (based on the closing price of Digital Realty Trust, Inc.s common stock on December 31, 2013 of $49.12). For this purpose, our total enterprise value is defined as the sum of the market value of Digital Realty Trust, Inc.s

common stock (which may decrease, thereby increasing our debt to total enterprise value ratio), excluding options issued under our incentive award plan, plus the liquidation value of Digital
Realty Trust, Inc.s preferred stock, plus the aggregate value of our operating partnership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 and Class C Units), plus the book value of our total consolidated indebtedness.

The variable rate debt shown above bears interest at interest rates based on various one-month LIBOR, EURIBOR, GBP LIBOR, SIBOR, BBR, HIBOR, JPY LIBOR and CDOR rates, depending on the respective agreement
governing the debt, including our global revolving credit facility and unsecured term loan. Assuming maturity of the 2029 Debentures at its first redemption date in April 2014, as of December 31, 2013, our debt had a weighted average term to
initial maturity of approximately 4.9 years (approximately 5.2 years assuming exercise of extension options).

The increases in net cash provided by operating activities from 2012 to 2013 and from 2011 to 2012 were
due to increased revenues from new leasing at our same store properties, completed and leased development space and our acquisition of new operating properties which was partially offset by increased operating and interest expenses. We acquired 7,
15 and 10 properties during the years ended December 31, 2013, 2012 and 2011, respectively.

Net cash used in investing
activities decreased in 2013 as compared to 2012, as we had a decrease in cash paid for acquisitions for the year ended December 31, 2013 ($170.3 million) as compared to the same period in 2012 ($1.6 billion) offset by an increase in cash paid
for capital expenditures for the year ended December 31, 2013 ($1.2 billion) as compared to the same period in 2012 ($845.8 million) along with proceeds from the contribution of properties to the joint venture with Prudential in September 2013
($328.6 million).

The decrease in net cash provided by financing activities was primarily due to higher net borrowings
during the year ended December 31, 2012 (net proceeds of $991.8 million) as compared to the year ended December 31, 2013 (net proceeds of $2.1 million), the issuance of Digital Realty Trust, Inc.s series F preferred stock
in April 2012 (net proceeds of $176.2 million) and common stock in its underwritten public offering in July 2012 (net proceeds of $797.2 million) along with the issuance of our 2022 Notes (net proceeds of $296.1 million) in September 2012
offset by the issuance of our 2025 Notes (net proceeds of $630.0 million) in January 2013 and Series G preferred stock (net proceeds of $241.5 million) in April 2013. The increase in dividend and distribution payments for the year
ended December 31, 2013 as compared to the same period in 2012 was due to an increase in the number of shares outstanding and dividend amount per share of common stock in 2013 as compared to 2012 and the payment of dividends on our series F and
series G preferred stock during the year ended December 31, 2013, which series of preferred stock were not outstanding for the fullor, in the case of the Series G preferred stock, any portion of the year ended December 31,
2012.

The increase in net cash provided by financing activities was primarily due to net borrowings during the year ended
December 31, 2012 (net proceeds of $991.8 million) as compared to net repayments for the year ended December 31, 2011 (net repayments of $234.0 million), the issuance of Digital Realty Trust, Inc.s series F preferred stock
in April 2012 (net proceeds of $176.2 million) and common stock in its underwritten public offering in July 2012 (net proceeds of $797.2 million) along with the issuance of our 2022 Notes (net proceeds of $296.1 million) in September 2012
offset by the issuance of our 2021 Notes (net proceeds of $395.8 million), common stock (net proceeds of $455.6 million) and Series E preferred stock (net proceeds of $277.7 million) during the year ended December 31, 2011.
The increase in dividend and distribution payments for the year ended December 31, 2012 as compared to the same period in 2011 was due to an increase in the number of shares outstanding and dividend amount per share of common stock in 2012 as
compared to 2011 and the payment of dividends on our series E and series F preferred stock during the year ended December 31, 2012, which series of preferred stock were not outstanding for the fullor, in the case of the Series F preferred
stock, any portion of theyear ended December 31, 2011.

The decrease in net cash provided by financing activities was primarily due to higher net borrowings
during the year ended December 31, 2012 (net proceeds of $991.8 million) as compared to the year ended December 31, 2013 (net proceeds of $2.1 million), general partner contributions in connection with Digital Realty Trust,

preferred stock offering in April 2013 (net proceeds of $241.5 million). The increase in distribution payments for the year ended December 31, 2013 as compared to the same period in 2012 was due to an increase in the number of units
outstanding and distribution amount per common unit in 2013 as compared to 2012 and the payment of distributions on our series F and series G preferred units during the year ended December 31, 2013, which series of preferred units were not

million) during the year ended December 31, 2011. The increase in distribution payments for the year ended December 31, 2012 as compared to the same period in 2011 was due to an increase in the number of units outstanding and distribution

Noncontrolling Interests in
Operating Partnership

Noncontrolling interests relate to the common units in our operating partnership that are not owned
by Digital Realty Trust, Inc., which, as of December 31, 2013, amounted to 2.3% of our operating partnership common units. In conjunction with our formation, GI Partners received common units, in exchange for contributing ownership interests in
properties to our operating partnership. Also, our operating partnership issued common units to third party sellers in connection with our acquisition of real estate interests from such third parties.

Limited partners who acquired common units in connection with our formation have the right
to require our operating partnership 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. Pursuant to registration rights agreements we entered into with GI Partners and the other third party contributors, we filed a shelf registration statement covering the issuance of the shares of our common stock
issuable upon redemption of the common units, and the resale of those shares of common stock by the holders. As of March 31, 2007, GI Partners no longer had an ownership interest in our operating partnership.

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, or NAREIT. FFO represents net income (loss) available to common stockholders (computed in accordance with U.S. GAAP), excluding gains (or losses) from sales of property, impairment charges, 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, 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 leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effect
and could materially impact our financial condition and results from operations, the utility of FFO as a measure of our performance is limited. Other REITs may not calculate FFO in accordance with the NAREIT definition and, accordingly, our FFO may
not be comparable to such other REITs FFO. Accordingly, FFO should be considered only as a supplement to net income as a measure of our performance.

New Accounting Pronouncements Issued But Not Yet Adopted

In 2013, the Financial Accounting Standards Board (FASB) issued new accounting guidance clarifying the accounting for the
release of a cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit
activity or a business within a foreign entity. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2013. We do not anticipate that this adoption will have a
significant impact on our financial position, results of operations, or cash flows.

In 2013, the FASB issued new accounting
guidance clarifying the accounting for obligations resulting from joint and several liability arrangements for which the total amount under the arrangement is fixed at the reporting date. The new standard is effective for fiscal years, and interim
periods within those fiscal years, beginning on or after December 15, 2013. We do not anticipate that this adoption will have a significant impact on our financial position, results of operations, or cash flows.

|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 rating 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 December 31, 2013, our consolidated debt was as follows (in millions):

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

For the years ended December 31, 2013 and 2012, we had foreign operations in the United Kingdom, Ireland, France, The Netherlands, Switzerland, Canada, Singapore, Australia and Hong Kong as well as
Japan in the year ended December 31, 2013, and, as such, are subject to risk from the effects of exchange rate movements of foreign currencies, which may affect future costs and cash flows. Our foreign operations are conducted in the British
pound sterling, Euro, Swiss franc, Australian dollar, Singapore dollar, Canadian dollar, Hong Kong dollar and the Japanese yen. Our primary currency exposures are to the British pound sterling, Euro and the Singapore dollar. We attempt to mitigate a
portion of the risk of currency fluctuation by financing our investments in the local currency denominations, although there can be no assurance that this will be effective. As a result, changes in the relation of any such foreign currency to U.S.
dollars may affect our revenues, operating margins and distributions and may also affect the book value of our assets and the amount of stockholders equity. For the years ended December 31, 2013, 2012 and 2011, operating revenues from
properties outside the United States contributed $349.1 million, $228.9 million and $116.7 million, respectively, which represented 23.6%, 17.9% and 11.0% of our operating revenues, respectively. Net investment in properties outside the United
States was $2.7 billion and $2.5 billion as of December 31, 2013 and 2012, respectively.

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, 2013. 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 (1992). Based on our assessment, management concluded that as of December 31, 2013, 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 97.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

Digital Realty Trust, Inc.:

We have audited the accompanying consolidated balance sheets of Digital Realty Trust, Inc. (the Company) and subsidiaries as of December 31, 2013 and 2012, and the related consolidated income
statements, statements of comprehensive income, equity, and cash flows for each of the years in the three-year period ended December 31, 2013. In connection with our audits of the consolidated financial
statements, we also have audited financial statement schedule III, properties and accumulated depreciation. These consolidated financial statements and financial statement schedule III are the responsibility of the Companys management. Our
responsibility is to express an opinion on these consolidated financial statements and financial statement schedule III based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position
of Digital Realty Trust, Inc. and subsidiaries as of December 31, 2013 and 2012, and the results of their operations and their cash flows for each of the years in the three-year period ended
December 31, 2013, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the related financial statement schedule III, properties and accumulated depreciation, when considered in relation to the basic
consolidated financial statements taken as a whole, present fairly, in all material respects, the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Digital Realty Trust, Inc.s internal control over financial reporting as of
December 31, 2013, based on criteria established in Internal ControlIntegrated Framework(1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated February 28, 2014
expressed an unqualified opinion on the effectiveness of the Companys internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

Digital Realty Trust, Inc.:

We have audited Digital Realty Trust, Inc.s (the Company) internal control over financial reporting as of December 31, 2013, based on criteria established in Internal ControlIntegrated
Framework(1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Companys management is responsible for maintaining effective internal control over financial reporting and for its
assessment of the effectiveness of internal control over financial reporting, included in the accompanying Managements Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the
Companys internal control over financial reporting based on our audit.

We conducted our audit in accordance with the
standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in
all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal
control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those policies and
procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management
and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may
deteriorate.

In our opinion, Digital Realty Trust, Inc. maintained, in all material respects, effective internal control over
financial reporting as of December 31, 2013, based on criteria established in Internal Control  Integrated Framework(1992) issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Digital Realty Trust, Inc. and subsidiaries as
of December 31, 2013 and 2012, and the related consolidated income statements, statements of comprehensive income, equity, and cash flows for each of the years in the three-year period ended December 31, 2013, and the financial statement
schedule III, properties and accumulated depreciation, and our report dated February 28, 2014 expressed an unqualified opinion on those consolidated financial statements and financial statement schedule III.

DIGITAL REALTY TRUST, L.P. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2013 and 2012

1. Organization and Description of Business

Digital Realty Trust, Inc. through its controlling interest in Digital Realty Trust, L.P. (the Operating Partnership)
and the subsidiaries of the Operating Partnership (collectively, we, our, us or the Company) is engaged in the business of owning, acquiring, developing and managing technology-related real estate. The Company is focused on providing customer driven
datacenter solutions for domestic and international tenants across a variety of industry verticals ranging from financial services, cloud and information technology services, to manufacturing, energy, health care and consumer products. As of
December 31, 2013, our portfolio consisted of 131 properties, including 12 properties held as investments in unconsolidated joint ventures and developable land, of which 104 are located throughout North America, 22 are located in Europe, three
are located in Australia and two are located in Asia. We are diversified in major markets where corporate datacenter and technology tenants are concentrated, including the Boston, Chicago, Dallas, Los Angeles, New York Metro, Northern Virginia,
Phoenix, San Francisco and Silicon Valley metropolitan areas in the United States, Amsterdam, Dublin, London and Paris markets in Europe and Singapore, Sydney, Melbourne, Hong Kong and Osaka markets in the Asia Pacific region. The portfolio consists
of Internet gateway and corporate datacenter properties, technology manufacturing properties and regional or national headquarters of technology companies.

The Operating Partnership was formed on July 21, 2004 in anticipation of Digital Realty Trust, Inc.s initial public offering (IPO) on November 3, 2004 and commenced operations on that
date. As of December 31, 2013, Digital Realty Trust, Inc. owns a 97.7% common interest and a 100% preferred interest in the Operating Partnership. As sole general partner of the Operating Partnership, Digital Realty Trust, Inc. has the full,
exclusive and complete responsibility for the Operating Partnerships day-to-day management and control. The limited partners of the Operating Partnership do not have rights to replace Digital Realty Trust, Inc. as the general partner nor do
they have participating rights, although they do have certain protective rights.

2. Summary of Significant Accounting Policies

(a) Principles of Consolidation and Basis of Presentation

The accompanying consolidated financial statements include all of the accounts of Digital Realty Trust, Inc., the Operating Partnership
and the subsidiaries of the Operating Partnership. Intercompany balances and transactions have been eliminated.

The notes to
the consolidated financial statements of Digital Realty Trust, Inc. and the Operating Partnership have been combined to provide the following benefits:



| |  |  | enhancing investors understanding of the Company and the Operating Partnership 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 Company and the Operating Partnership; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | creating time and cost efficiencies through the preparation of one set of notes instead of two separate sets of notes.
| | - |  | ----------------------------------------------------------------------------------------------------------------------

There are few differences between the Company and the Operating Partnership, which are reflected in these consolidated financial
statements. We believe it is important to understand the differences between the Company and the Operating Partnership in the context of how we operate as an interrelated consolidated company. Digital Realty Trust, Inc.s only material asset is
its ownership of partnership interests of the Operating Partnership. As a

result, Digital Realty Trust, Inc. does not conduct business itself, other than acting as the sole general partner of the Operating Partnership, issuing public equity from time to time and
guaranteeing certain unsecured debt of the Operating Partnership and certain of its subsidiaries. Digital Realty Trust, Inc. itself does not hold any indebtedness but guarantees the unsecured debt of the Operating Partnership and certain of its
subsidiaries, as disclosed in these notes. The Operating Partnership holds substantially all the assets of the Company and holds the ownership interests in the Companys joint ventures. The Operating Partnership conducts the operations of the
business and is structured as a partnership with no publicly traded equity. Except for net proceeds from public equity issuances by Digital Realty Trust, Inc., which are generally contributed to the Operating Partnership in exchange for partnership
units, the Operating Partnership generates the capital required by the Companys business through the Operating Partnerships operations, by the Operating Partnerships direct or indirect incurrence of indebtedness or through the
issuance of partnership units.

The presentation of noncontrolling interests in operating partnership, stockholders
equity and partners capital are the main areas of difference between the consolidated financial statements of Digital Realty Trust, Inc. and those of the Operating Partnership. The common limited partnership interests held by the limited
partners in the Operating Partnership are presented as limited partners capital within partners capital in the Operating Partnerships consolidated financial statements and as noncontrolling interests in operating partnership within
equity in Digital Realty Trust, Inc.s consolidated financial statements. The common and preferred partnership interests held by Digital Realty Trust, Inc. in the Operating Partnership are presented as general partners capital within
partners capital in the Operating Partnerships consolidated financial statements and as preferred stock, common stock, additional paid-in capital and accumulated dividends in excess of earnings within stockholders equity in Digital
Realty Trust, Inc.s consolidated financial statements. The differences in the presentations between stockholders equity and partners capital result from the differences in the equity issued at the Digital Realty Trust, Inc. and the
Operating Partnership levels.

To help investors understand the significant differences between the Company and the Operating
Partnership, these consolidated financial statements present the following separate sections for each of the Company and the Operating Partnership:



| |  |  | consolidated face financial statements; and
| | - |  | -------------------------------------------



| |  |  | the following notes to the consolidated financial statements:
| | - |  | -------------------------------------------------------------



| |  |  | Debt of the Company and Debt of the Operating Partnership;
| | - |  | ----------------------------------------------------------



| |  |  | Income per Share and Income per Unit;
| | - |  | -------------------------------------



| |  |  | Equity and Accumulated Other Comprehensive Loss, Net of the Company and Capital and Accumulated Other Comprehensive Income (Loss) of the Operating
Partnership; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Quarterly Financial Information.
| | - |  | --------------------------------

In the sections that combine disclosure of Digital Realty Trust, Inc. and the Operating Partnership, these notes refer to actions or holdings as being actions or holdings of the Company. Although the
Operating Partnership is generally the entity that enters into contracts and joint ventures and holds assets and debt, reference to the Company is appropriate because the business is one enterprise and the Company operates the business through the
Operating Partnership.

2013 and 2012



(b) Cash Equivalents

For the purpose of the consolidated statements of cash flows, we consider short-term investments with original maturities of 90 days or
less to be cash equivalents. As of December 31, 2013 and 2012, cash equivalents consist of investments in money market instruments.

(c) Investments in Real Estate

Investments in real estate are
stated at cost, less accumulated depreciation and amortization. Land is not depreciated. Depreciation and amortization are recorded on a straight-line basis over the estimated useful lives as follows:



|                           |  |                                                                         
|-------------------------- |  | ------------------------------------------------------------------------
|Acquired ground leases     |  | Terms of the related lease                                              
|Buildings and improvements |  | 5-39 years                                                              
|Tenant improvements        |  | Shorter of the estimated useful lives or the terms of the related leases

Improvements and replacements are capitalized when they extend the useful life, increase capacity, or
improve the efficiency of the asset. Repairs and maintenance are charged to expense as incurred.

(d) Investment in
Unconsolidated Joint Ventures

The Companys investment in unconsolidated joint ventures is accounted for using
the equity method, whereby the investment is increased for capital contributed and our share of the joint ventures net income and decreased by distributions we receive and our share of any losses of the joint ventures.

We amortize the difference between the cost of our investments in unconsolidated joint ventures and the book value of the underlying
equity into equity in earnings from unconsolidated affiliates on a straight-line basis consistent with the lives of the underlying assets.

(e) Impairment of Long-Lived Assets

We review each of our
properties for indicators that its carrying amount may not be recoverable. Examples of such indicators may include a significant decrease in the market price of the property, a significant adverse change in the extent or manner in which the property
is being used in its physical condition or expected to be used based on the underwriting at the time of acquisition, an accumulation of costs significantly in excess of the amount originally expected for the acquisition or development of the
property, or a history of operating or cash flow losses of the property. When such impairment indicators exist, we review an estimate of the future undiscounted net cash flows (excluding interest charges) expected to result from the real estate
investments use and eventual disposition and compare that estimate to the carrying value of the property. We consider factors such as future operating income, trends and prospects, as well as the effects of leasing demand, competition and
other factors. If our undiscounted net cash flow evaluation indicates that we are unable to recover the carrying value of a real estate investment, an impairment loss is recorded to the extent that the carrying value exceeds the estimated fair value
of the property. Management believes no impairment in the net carrying value of our investments in real estate has occurred.

(f) Purchase Accounting for Acquisition of Investments in Real Estate

Purchase accounting is applied to the assets and liabilities related to all real estate investments acquired from third parties. In
accordance with current accounting guidance,the fair value of the real estate acquired is allocated to the acquired tangible assets, consisting primarily of land, building and tenant improvements, and identified intangible assets and
liabilities, consisting of the value of above-market and below-market leases, other value of in-place leases, value of tenant relationships and acquired ground leases, based in each case on their fair

values. Loan premiums, in the case of above market rate loans, or loan discounts, in the case of below market loans, are recorded based on the fair value of any loans assumed in connection with
acquiring the real estate.

The fair values of the tangible assets of an acquired property are determined based on comparable
land sales for land and replacement costs adjusted for physical and market obsolescence for the improvements. The fair values of the tangible assets of an acquired property are also determined by valuing the property as if it were vacant, and the
as-if-vacant value is then allocated to land, building and tenant improvements based on managements determination of the relative fair values of these assets. Management determines the as-if-vacant fair value of a property based on
assumptions that a market participant would use, which is similar to methods used by independent appraisers. Factors considered by management in performing these analyses include an estimate of carrying costs during the expected lease-up periods
considering current market conditions and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and other operating expenses and estimates of lost rental revenue during the expected lease-up
periods based on current market demand. Management also estimates costs to execute similar leases including leasing commissions, tenant improvements, legal and other related costs.

In allocating the fair value of the identified intangible assets and liabilities of an acquired property, above-market and below-market
in-place lease values are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases
and (ii) estimated fair market lease rates from the perspective of a market participant for the corresponding in-place leases, measured, for above-market leases, over a period equal to the remaining non-cancelable term of the lease and, for
below-market leases, over a period equal to the initial term plus any below market fixed rate renewal periods. The leases we have acquired do not currently include any below market fixed rate renewal periods. The capitalized above-market lease
values are amortized as a reduction of rental income over the remaining non-cancelable terms of the respective leases. The capitalized below-market lease values, also referred to as acquired lease obligations, are amortized as an increase to rental
income over the initial terms of the respective leases and any below market fixed rate renewal periods.

In addition to the
intangible value for above market leases and the intangible negative value for below market leases, there is intangible value related to having tenants leasing space in the purchased property, which is referred to as in-place lease value and tenant
relationship value. Such value results primarily from the buyer of a leased property avoiding the costs associated with leasing the property and also avoiding rent losses and unreimbursed operating expenses during the lease up period. The estimated
avoided costs and avoided revenue losses are calculated and this aggregate value is allocated between in-place lease value and tenant relationships based on managements evaluation of the specific characteristics of each tenants lease;
however, the value of tenant relationships has not been separated from in-place lease value for our real estate because such value and its consequence to amortization expense is immaterial for these particular acquisitions. The value of in-place
leases exclusive of the value of above-market in-place leases is amortized to expense over the estimated term (including renewal and extension assumptions) of the respective leases. If a lease were to be terminated prior to its estimated term, all
unamortized amounts relating to that lease would be written off.

(g) Capitalization of Costs

Direct and indirect project costs that are clearly associated with the development of properties are capitalized as incurred. Project
costs include all costs directly associated with the development of a property, including construction costs, interest, property taxes, insurance, legal fees and costs of personnel working on the project. Indirect costs that do not clearly relate to
the projects under development are not capitalized and are charged to expense as incurred.

Capitalization of costs begins when the activities necessary to get the development
project ready for its intended use begins, which include costs incurred before the beginning of construction. Capitalization of costs ceases when the development project is substantially complete and ready for its intended use. Determining when a
development project commences, and when it is substantially complete and ready for its intended use involves a degree of judgment. We generally consider a development project to be substantially complete and ready for its intended use upon receipt
of a certificate of occupancy. We cease cost capitalization if activities necessary for the development of the property have been suspended. Capitalized costs are allocated to the specific components of a project that are benefited.

During the second quarter of 2013, in accordance with U.S. GAAP, we refined our capitalization practice related to operating expenditures
which could have been capitalized, but had been expensed. Previously, operating expenditures totaling $10,000 or less that could have been capitalized had been expensed as incurred for efficiency purposes. Under our refined capitalization practice,
retrospective to January 1, 2013, such expenses are now capitalized. Additionally, we conformed the construction period completion date, which is when capitalization of construction period operating costs ceases, with our construction period
interest capitalization policy. Previously, capitalization of construction period operating costs ceased upon the commissioning date. Retrospective to January 1, 2013, capitalization of construction period operating costs now ceases on receipt of
the certificate of occupancy, among other factors. During the year ended December 31, 2013, the total incremental amounts capitalized that would have been recorded as rental property operating expense under our previous policies was approximately
$9.5 million.

During the years ended December 31, 2013, 2012 and 2011, we capitalized interest of approximately
$26.3 million, $21.5 million and $17.9 million, respectively. During the years ended December 31, 2013, 2012 and 2011, we capitalized amounts relating to compensation expense of employees direct and incremental to construction and
successful leasing activities of approximately $37.6 million, $31.6 million and $24.7 million, respectively. Cash flows from capitalized leasing costs of $57.5 million, $40.1 million and $28.2 million are included in improvements to and advances for
investments in real estate in cash flows from investing activities in the consolidated statements of cash flows for the years ended December 31, 2013, 2012 and 2011, respectively.

(h) Deferred Leasing Costs

Leasing commissions and other direct and indirect costs associated with the acquisition of tenants are capitalized and amortized on a straight line basis over the terms of the related leases.

(i) Foreign Currency Translation

Assets and liabilities of our subsidiaries outside the United States with non-U.S. dollar functional currencies are translated into U.S. dollars using exchange rates as of the balance sheet dates. Income
and expenses are translated using the average exchange rates for the reporting period. Foreign currency translation adjustments are recorded as a component of other comprehensive income.

(j) Deferred Financing Costs

Loan fees and costs are capitalized and amortized over the life of the related loans on a straight-line basis, which approximates the effective interest method. Such amortization is included as a
component of interest expense.

(k) Restricted Cash

Restricted cash consists of deposits for real estate taxes and insurance and other amounts as required by our loan agreements including
funds for leasing costs and improvements related to unoccupied space.

(l) Offering Costs

Underwriting commissions and other offering costs are reflected as a reduction in additional paid-in capital, or in the case of preferred
stock, as a reduction of the carrying value of preferred stock.

(m) Share Based Compensation

We account for share based compensation using the fair value method of accounting. The estimated fair value of restricted stock granted by
us is being amortized on a straight-line basis over the vesting period. The estimated fair value of the long-term incentive units and Class C Units (discussed in note 13) granted by us is being amortized on a straight-line basis over the expected
service period.

For share based compensation awards with performance conditions, we estimate the fair value of the award
for each of the possible performance condition outcomes and amortize the compensation cost based on managements projected performance outcome. In the instance managements projected performance outcome changes prior to the final
measurement date, compensation cost is adjusted accordingly.

(n) Accounting for Derivative Instruments and Hedging
Activities

We account for our derivative instruments and hedging activities in accordance with the accounting standard
for derivative and hedging activities. The accounting standard requires us to measure every derivative instrument (including certain derivative instruments embedded in other contracts) at fair value and record them in the balance sheet as either an
asset or liability.

The effective portion of changes in the fair value of derivatives designated and that qualify as cash
flow hedges is recorded in accumulated other comprehensive income (loss) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of the
derivatives is recognized directly in earnings. During the years ended December 31, 2013, 2012 and 2011, respectively, there were no ineffective portions to our interest rate swaps.

We actively manage our ratio of fixed-to-floating rate debt. To manage our fixed and floating rate debt in a cost-effective manner, we,
from time to time, enter into interest rate swap agreements as cash flow hedges, under which we agree to exchange various combinations of fixed and/or variable interest rates based on agreed upon notional amounts. We do not enter into derivative
instruments for trading purposes.

(o) Income Taxes

Digital Realty Trust, Inc. (the Parent Company) has elected to be treated and believes that it has been organized and has operated in a
manner that has enabled the Parent Company to qualify as a REIT for federal income tax purposes. As a REIT, the Parent Company generally is not required to pay federal corporate income taxes on its taxable income to the extent it is currently
distributed to its stockholders.

However, qualification and taxation as a REIT depend upon the Parent Companys ability
to meet the various qualification tests imposed under the Internal Revenue Code of 1986, as amended (the Code), including tests related to annual operating results, asset composition, distribution levels and diversity of stock ownership.
Accordingly, no assurance can be given that the Parent Company has been organized or has operated or will continue to operate in a manner so as to qualify or remain qualified as a REIT. If the Parent Company fails to qualify as a REIT in any taxable
year, it will be subject to federal income tax (including any applicable alternative minimum tax) on its taxable income at regular corporate tax rates.

The Operating Partnership is a partnership and is not required to pay federal income tax. Instead, taxable income is allocated to its partners, who include such amounts on their federal income tax
returns. As such, no

provision for federal income taxes has been included in the Operating Partnerships accompanying consolidated financial statements.

Even if the Parent Company and the Operating Partnership are not subject to federal income taxes, the Company is subject to foreign,
state and local income taxes in the jurisdictions in which it conducts business. The Companys U.S. consolidated taxable REIT subsidiary is subject to both federal and state income taxes to the extent there is taxable income. Accordingly, the
Company recognizes and accrues income taxes for its taxable REIT subsidiaries, certain states and non-U.S. jurisdictions, as appropriate.

We assess our significant tax positions in accordance with U.S. GAAP for all open tax years and determine whether we have any material unrecognized liabilities from uncertain tax benefits. If a tax
position is not considered more-likely-than-not to be sustained solely on its technical merits, no benefits of the tax position are to be recognized (for financial statement purposes). As of December 31, 2013 and 2012, we have no
assets or liabilities for uncertain tax positions. We classify interest and penalties from significant uncertain tax positions as interest expense and operating expense, respectively, in our consolidated statements of operations. For the years ended
December 31, 2013, 2012 and 2011, we had no such interest or penalties. The tax year 2010 and thereafter remain open to examination by the major taxing jurisdictions with which the Parent Company and its subsidiaries file tax returns.

See Note 10 for further discussion on income taxes.

(p) Presentation of Transactional-based Taxes

We account for transactional-based taxes, such as value added tax, or VAT, for our international properties on a net basis.

(q) Revenue Recognition

All leases are classified as operating
leases and minimum rents are recognized on a straight-line basis over the terms of the leases. The excess of rents recognized over amounts contractually due pursuant to the underlying leases is included in deferred rent in the accompanying
consolidated balance sheets and contractually due but unpaid rents are included in accounts and other receivables.

Tenant
reimbursements for real estate taxes, common area maintenance, and other recoverable costs are recognized in the period that the expenses are incurred. Lease termination fees, which are included in other income in the accompanying statements of
operations, are recognized over the new remaining term of the lease, effective as of the date the lease modification is finalized, and assuming collection is probable.

A provision for loss is made if the collection of the receivable balances related to contractual rent, rent recorded on a straight-line basis, tenant reimbursements and lease termination fees are
considered to be doubtful.

(r) Asset Retirement Obligations

We record accruals for estimated retirement obligations as required by current accounting guidance. The amount of asset retirement
obligations relates primarily to estimated asbestos removal costs at the end of the economic life of properties that were built before 1984. As of December 31, 2013 and December 31, 2012, the amount included in accounts payable and other
accrued liabilities on our consolidated balance sheets was approximately $1.7 million and $1.7 million, respectively.

(s) Fee Income

Occasionally, customers engage the company for certain consulting services. The nature of these services historically involves property management, construction management, and assistance with financing.

2013 and 2012



revenue recognition of these services can be different, depending on whether the arrangements are service revenue or contractor type revenue.

Service revenues are typically recognized on an equal monthly basis based on the minimum fee to be earned. The monthly amounts could be
adjusted depending on if certain performance milestones are met.

Fee income also includes management fees. These fees
arise from contractual agreements with entities in which we have a noncontrolling interest. The management fees are recognized as earned under the respective agreements. Management and other fee income related to partially owned entities are
recognized to the extent attributable to the unaffiliated interest.

Contractor type revenue for long-term contracts is
recognized under the percentage-of-completion method of accounting. Revenues are determined by measuring the percentage of total costs incurred to date to estimated total costs for each construction management contract based on current estimates of
costs to complete. Contract costs include all labor and benefits, materials, subcontracts, and an allocation of indirect costs related to contract performance. Indirect costs are allocated to projects based upon labor hours charged. Third party
costs are included in construction management expense and their reimbursements are included in construction management revenue to the extent that the Company is the primary obligor for the third party costs. Otherwise, construction management
revenue and expense is reflected net of third party costs. As long-term design-build projects extend over one or more years, revisions in cost and estimated earnings during the course of the work are reflected in the accounting period in which the
facts which require the revision become known. At the time a loss on a design-build project becomes known, the entire amount of the estimated loss is recognized in the condensed consolidated financial statements. Change orders are recognized when
they are approved by the client.

Costs and estimated earnings in excess of billings on uncompleted construction management
projects are included in other assets in the condensed consolidated balance sheets. Billings in excess of costs and estimated earnings on uncompleted construction management projects are included in accounts payable and other accrued liabilities in
the condensed consolidated balance sheets. Customers are billed on a monthly basis at the end of each month, which can be in advance of work performed.

(t) Assets and Liabilities Measured at Fair Value

Fair value under
U.S. GAAP is a market-based measurement, not an entity-specific measurement. Therefore, our fair value measurements are determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for
considering market participant assumptions in fair-value measurements, we use a fair-value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable
inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entitys own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).

Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability
to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active
markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable
inputs for the asset or liability which are typically based on an entitys own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair-value measurement is based on inputs from
different levels of the fair-value hierarchy, the level in the fair-value hierarchy within which the entire fair-value measurement falls is based on the lowest level input that is

significant to the fair-value measurement in its entirety. Our assessment of the significance of a particular input to the fair-value measurement in its entirety requires judgment, and considers
factors specific to the asset or liability.

(u) Transactions Expense

Transactions expense includes acquisition-related expenses and other business development expenses, which are expensed as
incurred. Acquisition-related expenses include closing costs, broker commissions and other professional fees, including legal and accounting fees related to acquisitions and potential acquisitions.

(v) Managements Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates made. On an on-going basis, we
evaluate our estimates, including those related to the valuation of our real estate properties, contingent consideration, accounts receivable and deferred rent receivable, performance-based equity compensation plans, the completeness of accrued
liabilities and Digital Realty Trust, Inc.s qualification as a REIT. We base our estimates on historical experience, current market conditions, and various other assumptions that are believed to be reasonable under the circumstances. Actual
results may vary from those estimates and those estimates could vary under different assumptions or conditions.

(w)
Segment and Geographic Information

All of our properties generate similar revenues and expenses related to tenant rent
and reimbursements and operating expenses. The delivery of our products is consistent across all properties and although services are provided to a wide range of customers, the types of real estate services provided to them are standardized
throughout the portfolio. As such, the properties in our portfolio have similar economic characteristics and the nature of the products and services provided to our customers and the method to distribute such services are consistent throughout the
portfolio. Consequently, our properties qualify for aggregation into one reporting segment.

Operating revenues from
properties in the United States were $1.1 billion, $1.1 billion and $946.0 million and outside the United States were $349.1 million, $228.9 million and $116.7 million for the years ended December 31, 2013, 2012 and 2011,
respectively. We had long-lived assets located in the United States of $5.6 billion, $5.0 billion and $4.3 billion and outside the United States of $2.7 billion, $2.5 billion and $1.0 billion as of December 31, 2013, 2012 and 2011,
respectively.

Operating revenues from properties located in the United Kingdom were $197.0 million, $117.2 million and
$43.6 million, or 13.3%, 9.2% and 4.1% of total operating revenues for the years ended December 31, 2013, 2012 and 2011, respectively. No other foreign country comprised more than 10% of total operating revenues for each of these years. We
had long-lived assets located in the United Kingdom of $1.8 billion, $1.7 billion and $356.0 million, or 21.1%, 22.3% and 6.8% of total long-lived assets as of December 31, 2013, 2012 and 2011, respectively. No other foreign country comprised
more than 10% of total long-lived assets as of each of December 31, 2013, 2012 and 2011.

(x) Recent Accounting
Pronouncements

assets that is a nonprofit activity or a business within a foreign entity. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning on or after
December 15, 2013. We do not anticipate that this adoption will have a significant impact on our financial position, results of operations, or cash flows.

In 2013, the FASB issued new accounting guidance clarifying the accounting for obligations resulting from joint and several liability arrangements for which the total amount under the arrangement is fixed
at the reporting date. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2013. We do not anticipate that this adoption will have a significant impact on our
financial position, results of operations, or cash flows.

|(9) | On July 11, 2012, we completed the acquisition of a three-property data center portfolio, totaling approximately 733,000 square feet, located in the greater London
area, referred to as the Sentrum Portfolio. The purchase price was £734.6 million (equivalent to approximately $1.1 billion based on the July 11, 2012 exchange rate of £1.00 to $1.55). In addition, non-cash consideration of
£56.5 million (or $87.6 million based on the July 11, 2012 exchange rate of £1.00 to $1.55) was recorded as the expected fair value of contingent consideration as required by prevailing accounting guidance. There was also a
non-cash purchase adjustment related to deferred taxes, which amounted to £68.6 million (or $106.3 million based on the July 11, 2012 exchange rate of £1.00 to $1.55). The purchase price was paid in cash funded with proceeds
from our common stock offering in July 2012 along with borrowings under our global revolving credit facility.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)

December 31,
2013 and 2012



Our investment in the 2001 Sixth Avenue joint venture included in our consolidated
balance sheet exceeds our equity presented in the joint ventures balance sheet since our purchase accounting adjustments are not pushed down to the joint venture.

In March 2012, we entered into a joint venture with Savvis, Inc., a CenturyLink company. On June 26, 2012, this unconsolidated joint venture acquired a 164,000 square foot property in Hong Kong. The
property is located at 33 Chun Choi Street in Hong Kong. As of December 31, 2013, we have contributed approximately $57.4 million to this joint venture.

PREI ® Joint Venture

On September 27, 2013, we formed a joint venture with an investment fund managed by
Prudential Real Estate Investors (PREI®). We contributed nine Powered Base Building® data centers valued at approximately $366.4 million plus 20% of $2.8 million of closing costs. The PREI®-managed fund contributed cash equal to their 80% interest in the joint venture assets at fair value and we retained
a 20% interest. The joint venture is structured to provide a current annual preferred return from cash flow first to the
PREI®-managed interest, then to our interest, after which a portion of any excess cash flows is shared by the
partners based on their respective interests and the remaining portion is paid to us as a promote interest. We perform the day-to-day accounting and property management functions for the joint venture and, as such, will earn a management fee.
Although we are the managing member of the joint venture and manage the day-to-day activities, all significant decisions, including approval of annual budgets, require approval of the PREI-managed member. Thus, we concluded we do not own a
controlling interest and will account for our interest in the joint venture as an equity method investment.

The joint venture has arranged a $185.0 million five-year unsecured bank loan at LIBOR plus 180 basis points, representing a loan-to-value ratio of approximately 50%. Proceeds from the debt offset the
contribution amounts required of the partners. The transaction generated approximately $328.6 million of net proceeds to us, comprised of our share of the initial draw-down on the bank loan in addition to the PREI® funds equity contribution, less our share of closing costs and accordingly we recognized a gain of
approximately $115.6 million on the sale of the 80% interest in the nine properties during the year ended December 31, 2013.

The operations of properties that we contributed to the joint venture are not recorded as discontinued operations because of our continuing involvement with these investment properties. Differences
between the Companys investment in the joint venture and the amount of the underlying equity in net assets of the joint venture are due to basis differences resulting from the Companys equity investment recorded at its historical basis
versus the fair value of the Companys contributed interest in the joint venture. Our proportionate share of the earnings or losses related to this unconsolidated joint venture is reflected as equity in earnings of unconsolidated joint ventures
on the accompanying consolidated income statements.

The table below presents properties contributed to
the PREI® joint venture at their fair value as of the contribution date (dollars in thousands).

Global
Revolving Credit Facility

On August 15, 2013, the Operating Partnership refinanced its revolving credit facility,
which we refer to as the global revolving credit facility, increasing its total borrowing capacity to $2.0 billion from $1.8 billion. The global revolving credit facility has an accordion feature that would enable us to increase the borrowing
capacity of the credit facility to $2.55 billion, subject to the receipt of lender commitments and other conditions precedent. The refinanced facility matures on November 3, 2017, with two six-month extension options. The interest rate for
borrowings under the expanded facility equals the applicable index plus a margin which is based on the credit rating of our long-term debt and is currently 110 basis points. An annual facility fee on the total commitment amount of the facility,
based on the credit rating of our long-term debt and currently 20 basis points, is payable quarterly. Funds may be drawn in U.S., Canadian, Singapore, Australian and Hong Kong dollars, as well as Euro, British pound sterling, Swiss franc, Japanese
yen and Mexican peso denominations. As of December 31, 2013, borrowings under the global revolving credit facility bore interest at an overall blended rate of 1.60% comprised of 1.27% (U.S. dollars), 1.33% (Euros), 3.70% (Australian dollars),
1.31% (Hong Kong dollars), 1.21% (Japanese yen) and 2.32% (Canadian dollars). The interest rates are based on 1-month LIBOR, 1-month EURIBOR, 1-month BBR, 1-month HIBOR, 1-month JPY LIBOR and 1-month CDOR, respectively, plus a margin of 1.10%. The
facility also bore a base borrowing rate of 3.35% (USD) which is based on U.S. Prime Rate plus a margin of 0.10%. We have used and intend to use available borrowings under the global revolving credit facility to acquire additional properties, fund
development opportunities and to provide for working capital and other corporate purposes, including potentially for the repurchase, redemption or retirement of outstanding debt or preferred equity securities. As of December 31, 2013, we have
capitalized approximately $17.9 million of financing costs related to the global revolving credit facility. As of December 31, 2013, approximately $724.7 million was drawn under this facility and $20.6 million of letters of credit were issued.

The global revolving credit facility contains various restrictive covenants, including limitations on our ability to incur
additional indebtedness, make certain investments or merge with another company, and requirements to maintain financial coverage ratios, including with respect to unencumbered assets. In addition, the global revolving credit facility restricts
Digital Realty Trust, Inc. from making distributions to its stockholders, or redeeming or otherwise repurchasing shares of its capital stock, after the occurrence and during the continuance of an event of default, except in limited circumstances
including as necessary to enable Digital Realty Trust, Inc. to maintain its qualification as a REIT and to minimize the payment of income or excise tax. As of December 31, 2013, we were in compliance with all of such covenants.

Unsecured Term Loan

On August 15, 2013, we refinanced the senior unsecured multi-currency term loan facility, increasing its total borrowing capacity to
$1.0 billion from $750.0 million, and pursuant to the accordion feature total commitments can be increased up to $1.1 billion, subject to the receipt of lender commitments and other conditions precedent. The facility matures on April 16, 2017,
with two six-month extension options. Interest rates are based on our senior unsecured debt ratings and are currently 120 basis points over the applicable index for floating rate advances. Funds may be drawn in U.S, Singapore and Australian dollars,
as well as Euro and British pound sterling denominations with the option to add Hong Kong dollars and Japanese yen upon an accordion exercise. Based on exchange rates in effect at December 31, 2013, the balance outstanding is approximately
$1,021.0 million. We have used borrowings under the term loan for acquisitions, repayment of indebtedness, development, working capital and general corporate purposes. The covenants under this loan are consistent with our global revolving credit
facility and, as of December 31, 2013, we were in compliance with all of such covenants. As of December 31, 2013, we have capitalized approximately $8.4 million of financing costs related to the unsecured term loan.

Unsecured Senior Notes

Prudential Shelf Facility

On January 20, 2010, the Operating
Partnership closed the sale of $100.0 million aggregate principal amount of its senior unsecured term notes to Prudential Investment Management, Inc. and certain of its affiliates, or, collectively, Prudential, pursuant to a Note Purchase and
Private Shelf Agreement, which we refer to as the Prudential shelf facility. The notes were issued in two series referred to as the series D and series E notes. The series D notes have a principal amount of $50.0 million, an interest-only rate of
4.57% per annum and a five-year maturity, and the series E notes have a principal amount of $50.0 million, an interest-only rate of 5.73% per annum and a seven-year maturity. On February 3, 2010, the Operating Partnership closed the
sale of an additional $17.0 million aggregate principal amount of its senior unsecured term notes, which we refer to as the series F notes, to Prudential pursuant to the Prudential shelf facility. The series F notes have an interest-only rate of
4.50% per annum and a five-year maturity. We used the proceeds of the series D, series E and series F notes to fund acquisitions, to temporarily repay borrowings under our corporate revolving credit facility, to fund working capital and for
general corporate purposes. The sale of the series A ($25.0 million), series B ($33.0 million) and series C ($25.0 million) were completed in July 2008, November 2008 and January 2009, respectively. We may prepay the notes of any series, in
whole or in part, at any time at a price equal to the principal amount and accrued interest of the notes being prepaid, plus a make-whole provision. On December 8, 2010, the Operating Partnership and Prudential entered into an amendment to the
Note Purchase and Private Shelf Agreement, increasing the capacity of the Prudential shelf facility from $200.0 million to $250.0 million. Our ability to make additional issuances of notes under the Prudential shelf facility expired on July 24,
2011, with $50.0 million remaining unissued under the shelf facility. On July 25, 2011, we repaid the $25.0 million of 7.0% Series A unsecured notes under the Prudential shelf facility at maturity. On November 5, 2013, we repaid the $33.0
million of 9.32% Series B unsecured notes under the Prudential shelf facility at maturity. As of December 31, 2013 and 2012, there was $142.0 million and $175.0 million of unsecured senior notes outstanding, respectively.

On August 15, 2013, concurrent with the refinancing of the global revolving credit facility, the Operating Partnership and Digital
Realty Trust, Inc. and the other subsidiary guarantors set forth therein entered into Amendment No.1 to the Amended and Restated Note Purchase and Private Shelf Agreement with Prudential to conform the restrictive and financial covenants of the
original Prudential shelf facility that apply to the outstanding Series B, C, D, E and F Notes under the Prudential shelf facility to those in the global revolving

December 31, 2013. Due to the fact that the exchange feature for the 2029 Debentures must be settled in the common stock of Digital Realty Trust, Inc., accounting guidance on convertible debt instruments that requires the principal amount to be
settled in cash upon conversion does not apply.

DIGITAL REALTY TRUST, L.P. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)

December 31,
2013 and 2012



During the year ended December 31, 2011, the Operating Partnerships remaining
4.125% exchangeable senior debentures due August 15, 2026 (2026 Debentures) were redeemed and exchanged. On or after July 15, 2026, the 2026 Debentures would have been exchangeable at the then-applicable exchange rate for cash (up to the
principal amount of the 2026 Debentures) and, with respect to any excess exchange value, into cash, shares of Digital Realty Trust, Inc. common stock or a combination of cash and shares of Digital Realty Trust, Inc. common stock. The 2026 Debentures
also would have been exchangeable prior to July 15, 2026, but only upon the occurrence of certain specified events, including if the weighted average common stock price exceeded a specified strike price as of the end of a fiscal quarter. Using
the treasury stock method, 370,719 shares of common stock contingently issuable upon settlement of the excess exchange value were included as potentially dilutive common shares in determining diluted earnings per share for the year ended
December 31, 2011.

We have excluded the following potentially dilutive securities in the calculations above as they
would be antidilutive or not dilutive:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)

December 31,
2013 and 2012



During the year ended December 31, 2011, the remaining 2026 Debentures were
redeemed and exchanged. On or after July 15, 2026, the 2026 Debentures would have been exchangeable at the then-applicable exchange rate for cash (up to the principal amount of the 2026 Debentures) and, with respect to any excess exchange
value, into cash, shares of Digital Realty Trust, Inc. common stock or a combination of cash and shares of Digital Realty Trust, Inc. common stock. Pursuant to the terms of the Operating Partnerships agreement of limited partnership, the
Operating Partnership would have delivered to Digital Realty Trust, Inc. one common unit for each share of common stock issued upon exchange of the 2026 Debentures. The 2026 Debentures also would have been exchangeable prior to July 15, 2026,
but only upon the occurrence of certain specified events, including if the weighted average common stock price exceeded a specified strike price as of the end of a fiscal quarter. Using the treasury method, 370,719 common units contingently issuable
upon settlement of the excess exchange value were included as potentially dilutive common units in determining diluted earnings per unit for the year ended December 31, 2011.

We have excluded the following potentially dilutive securities in the calculations above as they would be antidilutive or not dilutive:

10. Income Taxes

Digital Realty Trust, Inc. (the Parent Company) has elected to be taxed as a REIT and believes that it has complied
with the REIT requirements of the Code. As a REIT, the Parent Company is generally not subject to corporate level federal income taxes on taxable income to the extent it is currently distributed to its stockholders. Since inception, the Parent
Company has distributed at least 100% of its taxable income annually and intends to do so for the tax year ending December 31, 2013. As such, no provision for federal income taxes has been included in the accompanying consolidated financial
statements for the years ended December 31, 2013, 2012 and 2011.

We have elected taxable REIT subsidiary (TRS) status
for some of our consolidated subsidiaries. In general, a TRS may provide services that would otherwise be considered impermissible for REITs and hold assets that REITs cannot hold directly. Income taxes for TRS entities were accrued, as necessary,
for the years ended December 31, 2013, 2012 and 2011.

For our TRS entities and foreign subsidiaries that are subject to
U.S. federal, state and foreign income taxes, deferred tax assets and liabilities are established for temporary differences between the financial reporting basis and the tax basis of assets and liabilities at the enacted tax rates expected to be in
effect when the temporary differences reverse. A valuation allowance for deferred tax assets is provided if we believe it is more likely than not that the deferred tax asset may not be realized, based on available evidence at the time the
determination is

made. An increase or decrease in the valuation allowance that results from the change in circumstances that causes a change in our judgment about the realizability of the related deferred tax
asset is included in income. Deferred tax assets (net of valuation allowance) and liabilities for our TRS entities and foreign subsidiaries were accrued, as necessary, for the years ended December 31, 2013, 2012 and 2011. As of
December 31, 2013, we had a net deferred tax liability of approximately $146.6 million primarily related to our foreign properties, comprised of a $110.4 million deferred tax asset, net of a $257.0 million deferred tax liability. The majority
of our net deferred tax liability relates to differences between tax and book basis of the assets acquired in the Sentrum Portfolio acquisition during 2012. In July 2013, we made certain immaterial measurement period adjustments to the provisional
amounts initially recorded for the net deferred tax liability recorded as part of the Sentrum acquisition, which closed in July 2012.

11. Equity and Accumulated Other Comprehensive Loss, Net

(a) Equity Distribution Agreements

On June 29, 2011, Digital Realty Trust, Inc. entered into new equity distribution agreements, which we refer to as the 2011 Equity
Distribution Agreements, with each of Merrill Lynch, Pierce, Fenner & Smith Incorporated, Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC, Deutsche Bank Securities Inc. and Morgan Stanley & Co. LLC, or the Agents,
under which it could issue and sell shares of its common stock having an aggregate offering price of up to $400.0 million from time to time through, at its discretion, any of the Agents as its sales agents. The sales of common stock made under the
2011 Equity Distribution Agreements will be made in at the market offerings as defined in Rule 415 of the Securities Act. For the year ended December 31, 2012, Digital Realty Trust, Inc. generated net proceeds of approximately $62.7
million from the issuance of approximately 1.0 million common shares under the 2011 Equity Distribution Agreements at an average price of $66.19 per share after payment of approximately $0.6 million of commissions to the sales agents and before
offering expenses. For the year ended December 31, 2011, Digital Realty Trust, Inc. generated net proceeds of approximately $280.0 million from the issuance of approximately 4.8 million common shares under the 2011 Equity Distribution
Agreements at an average price of $59.17 per share after payment of approximately $2.8 million of commissions to the sales agents and before offering expenses. No sales were made under the program during the year ended December 31, 2013. As of
December 31, 2013, shares of common stock having an aggregate offering price of $53.8 million remained available for offer and sale under the program.

(b) Convertible Preferred Stock

5.500% Series D Cumulative
Convertible Preferred Stock

On February 6, 2008, Digital Realty Trust, Inc. issued 13,800,000 shares of its 5.500%
series D cumulative convertible preferred stock, or the series D preferred stock. Dividends were cumulative on the series D preferred stock from the date of original issuance in the amount of $1.375 per share each year, which is equivalent to 5.500%
of the $25.00 liquidation preference per share. Dividends on the series D preferred stock were payable quarterly in arrears. The series D preferred stock did not have a stated maturity date and was not subject to any sinking fund or mandatory
redemption provisions. Upon liquidation, dissolution or winding up, the series D preferred stock ranked senior to Digital Realty Trust, Inc. common stock with respect to the payment of distributions and other amounts and ranked on parity with
Digital Realty Trust, Inc. series E preferred stock and series F preferred stock. Digital Realty Trust, Inc. was not allowed to redeem the series D preferred stock, except in limited circumstances to preserve its status as a REIT. Holders of the
series D preferred stock generally had no voting rights except for limited voting rights if Digital Realty Trust, Inc. failed to pay dividends for six or more quarterly periods (whether or not consecutive) and in certain other circumstances.

(c) Redeemable Preferred Stock

7.000% Series E Cumulative Redeemable Preferred Stock

On
September 15, 2011, Digital Realty Trust, Inc. issued 11,500,000 shares of its 7.000% series E cumulative redeemable preferred stock, or the series E preferred stock, for net proceeds of $277.2 million, after deducting underwriting discounts
and commissions and offering expenses. Dividends are cumulative on the series E preferred stock from the date of original issuance in the amount of $1.750 per share each year, which is equivalent to 7.000% of the $25.00 liquidation preference per
share. Dividends on the series E preferred stock are payable quarterly in arrears. The first dividend paid on the series E preferred stock on December 30, 2011 was a pro rata dividend from and including the original issue date to and including
December 31, 2011 in the amount of $0.515278 per share. The series E preferred stock does not have a stated maturity date and is not subject to any sinking fund or mandatory redemption provisions. Upon liquidation, dissolution or winding up,
the series E preferred stock will rank senior to Digital Realty Trust, Inc. common stock with respect to the payment of distributions and other amounts and rank on parity with Digital Realty Trust, Inc. series F cumulative redeemable and series G
cumulative redeemable preferred stock. Digital Realty Trust, Inc. is not allowed to redeem the series E preferred stock before September 15, 2016, except in limited circumstances to preserve its status as a REIT and upon specified change of
control transactions. On or after September 15, 2016, Digital Realty Trust, Inc. may, at its option, redeem the series E preferred stock, in whole or in part, at any time or from time to time, for cash at a redemption price of $25.00 per share,
plus all accrued and unpaid dividends on such series E preferred stock up to but excluding the redemption date. Holders of the series E preferred stock generally have no voting rights except for limited voting rights if Digital Realty Trust, Inc.
fails to pay dividends for six or more quarterly periods (whether or not consecutive) and in certain other circumstances. Upon the occurrence of specified changes of control, as a result of which neither Digital Realty Trust, Inc.s common
stock nor the common securities of the acquiring or surviving entity (or American Depository Receipts, or ADRs, representing such securities) is listed on the New York Stock Exchange, the NYSE Amex Equities or the NASDAQ Stock Market or listed or
quoted on a successor exchange or quotation system, each holder of series E preferred stock will have the right (unless, prior to the change of control conversion date specified in the Articles Supplementary governing the series E preferred stock,
Digital Realty Trust, Inc. has provided or provides notice of its election to redeem the series E preferred stock) to convert some or all of the series E preferred stock held by it into a number of shares of Digital Realty Trust, Inc.s common

Limited partners have the right to require the Operating Partnership to redeem part or all 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 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. Pursuant
to authoritative accounting guidance, Digital Realty Trust, Inc. evaluated whether it controls the actions or events necessary to issue the maximum number of shares that could be required to be delivered under the share settlement of the
noncontrolling Operating Partnership common and incentive units. Based on the results of this analysis, we concluded that the common and incentive Operating Partnership units met the criteria to be classified within equity.

The redemption value of the noncontrolling Operating Partnership common units and the vested incentive units was approximately $124.1
million and $161.5 million based on the closing market price of Digital Realty Trust, Inc. common stock on December 31, 2013 and 2012, respectively.

Under the terms of certain third parties (the eXchange parties) contribution agreements signed in the third quarter of 2004, we
agreed to indemnify each eXchange party against adverse tax consequences in the event the Operating Partnership directly or indirectly sold, exchanged or otherwise disposed of (whether by way of merger, sale of assets or otherwise) in a taxable
transaction any interest in 200 Paul Avenue or 1100 Space Park Drive until the earlier of November 3, 2013 or the date on which these contributors or certain transferees hold less than 25% of the Operating Partnership common units issued to
them in the formation transactions consummated concurrently with the IPO. Under the eXchange parties amended contribution agreement, the Operating Partnership agreed to make approximately $17.8 million of indebtedness available for guaranty by
the eXchange parties until the earlier of November 3, 2013 and the date on which these contributors or certain transferees hold less than 25% of the Operating Partnership common units issued to them in the formation transactions consummated
concurrently with the IPO, and we agreed to indemnify each eXchange party against adverse tax consequences if the Operating Partnership does not provide such indebtedness to guarantee.

(c) Allocations of Net Income and Net Losses to Partners

Except for special allocations to holders of profits interest units described below in note 13(a) under the heading Incentive
Plan-Long-Term Incentive Units, the Operating Partnerships net income will generally be allocated to the General Partner to the extent of the accrued preferred return on its preferred units, and then to the General Partner and the
Operating Partnerships limited partners in accordance with the respective percentage interests in the common units issued by the Operating Partnership. Net loss will generally be allocated to the General Partner and the Operating
Partnerships limited partners in accordance with the respective common percentage interests in the Operating Partnership until the limited partners capital is reduced to zero and any remaining net loss would be allocated to the General
Partner. However, in some cases, losses may be disproportionately allocated to partners who have guaranteed our debt. The allocations described above are

subject to special allocations relating to depreciation deductions and to compliance with the provisions of Sections 704(b) and 704(c) of the Code, and the associated Treasury Regulations.

(d) Partnership Units

Limited partners have the right to require the Operating Partnership to redeem part or all of their common units for cash based on the fair market value of an equivalent number of shares of the General
Partners common stock at the time of redemption. Alternatively, the General Partner may elect to acquire those common units in exchange for shares of the General Partners 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. Pursuant to authoritative accounting guidance, the Operating Partnership evaluated whether it controls the actions or events
necessary to issue the maximum number of shares that could be required to be delivered under the share settlement of the limited partners common units and the vested incentive units. Based on the results of this analysis, the Operating
Partnership concluded that the common and vested incentive Operating Partnership units met the criteria to be classified within capital.

The redemption value of the limited partners common units and the vested incentive units was approximately $124.1 million and $161.5 million based on the closing market price of Digital Realty
Trust, Inc.s common stock on December 31, 2013 and 2012, respectively.

13. Incentive Plan

Our Amended and Restated 2004 Incentive Award Plan (as defined below) provides for the grant of incentive awards to
employees, directors and consultants. Awards issuable under the Amended and Restated 2004 Incentive Award Plan include stock options, restricted stock, dividend equivalents, stock appreciation rights, long-term incentive units, cash performance
bonuses and other incentive awards. Only employees are eligible to receive incentive stock options under the Amended and Restated 2004 Incentive Award Plan. Initially, we had reserved a total of 4,474,102 shares of common stock for issuance pursuant
to the 2004 Incentive Award Plan, subject to certain adjustments set forth in the 2004 Incentive Award Plan. On May 2, 2007, Digital Realty Trust, Inc.s stockholders approved the First Amended and Restated Digital Realty Trust, Inc.,
Digital Services, Inc. and Digital Realty Trust, L.P. 2004 Incentive Award Plan (as amended, the Amended and Restated 2004 Incentive Award Plan). The Amended and Restated 2004 Incentive Award Plan increases the aggregate number of shares of stock
which may be issued or transferred under the plan by 5,000,000 shares to a total of 9,474,102 shares, and provides that the maximum number of shares of stock with respect to awards granted to any one participant during a calendar year will be
1,500,000 and the maximum amount that may be paid in cash during any calendar year with respect to any performance-based award not denominated in stock or otherwise for which the foregoing limitation would not be an effective limitation for purposes
of Section 162(m) of the Code will be $10.0 million.

As of December 31, 2013, 3,209,240 shares of common stock or
awards convertible into or exchangeable for common stock remained available for future issuance under the Amended and Restated 2004 Incentive Award Plan. Each long-term incentive unit and Class C Unit issued under the Amended and Restated 2004
Incentive Award Plan will count as one share of common stock for purposes of calculating the limit on shares that may be

issued under the Amended and Restated 2004 Incentive Award Plan and the individual award limit discussed above.

(a) Long-Term Incentive Units

Long-term incentive units, which are
also referred to as profits interest units, may be issued to eligible participants for the performance of services to or for the benefit of the Operating Partnership. Long-term incentive units, whether vested or not, will receive the same quarterly
per unit distributions as Operating Partnership common units, which equal per share distributions on Digital Realty Trust, Inc. common stock. Initially, long-term incentive units do not have full parity with common units with respect to liquidating
distributions. If such parity is reached, vested long-term incentive units may be converted into an equal number of common units of the Operating Partnership at any time, and thereafter enjoy all the rights of common units of the Operating
Partnership, including redemption rights.

In order to achieve full parity with common units, long-term incentive units must
be fully vested and the holders capital account balance in respect of such long-term incentive units must be equal to the capital account balance of a holder of an equivalent number of common units. The capital account balance attributable to
each common unit is generally expected to be the same, in part because of the amount credited to a partners capital account upon the partners contribution of property to the Operating Partnership, and in part because the partnership
agreement provides, in most cases, that allocations of income, gain, loss and deduction (which will adjust the partners capital accounts) are to be made to the common units on a proportionate basis. As a result, with respect to a number of
long-term incentive units, it is possible to determine the capital account balance of an equivalent number of common units by multiplying the number of long-term incentive units by the capital account balance with respect to a common unit.

A partners initial capital account balance is equal to the amount the partner paid (or contributed to the Operating
Partnership) for the partners units and is subject to subsequent adjustments, including with respect to the partners share of income, gain or loss of the Operating Partnership. Because a holder of long-term incentive units generally will
not pay for the long-term incentive units, the initial capital account balance attributable to such long-term incentive units will be zero. However, the Operating Partnership is required to allocate income, gain, loss and deduction to the
partners capital accounts in accordance with the terms of the partnership agreement, subject to applicable Treasury Regulations. The partnership agreement provides that holders of long-term incentive units will receive special allocations of
gain in the event of a sale or hypothetical sale of assets of the Operating Partnership prior to the allocation of gain to Digital Realty Trust, Inc. or other limited partners with respect to their common units. The amount of such
allocation will, to the extent of any such gain, be equal to the difference between the capital account balance of a holder of long-term incentive units attributable to such units and the capital account balance attributable to an equivalent number
of common units. If and when such gain allocation is fully made, a holder of long-term incentive units will have achieved full parity with holders of common units. To the extent that, upon an actual sale or a hypothetical sale of the
Operating Partnerships assets as described above, there is not sufficient gain to allocate to a holders capital account with respect to long-term incentive units, or if such sale or hypothetical sale does not occur, such
units will not achieve parity with common units.

The term hypothetical sale refers to circumstances that are not
actual sales of the Operating Partnerships assets but that require certain adjustments to the value of the Operating Partnerships assets and the partners capital account balances. Specifically, the partnership agreement provides
that, from time to time, in accordance with applicable Treasury Regulations, the Operating Partnership will adjust the value of its assets to equal their respective fair market values, and adjust the partners capital accounts, in accordance
with the terms of the

partnership agreement, as if the Operating Partnership sold its assets for an amount equal to their value. Times for making such adjustments generally include the liquidation of the Operating
Partnership, the acquisition of an additional interest in the Operating Partnership by a new or existing partner in exchange for more than a de minimis capital contribution, the distribution by the Operating Partnership to a partner of more than a
de minimis amount of partnership property as consideration for an interest in the Operating Partnership, in connection with the grant of an interest in the Operating Partnership (other than a de minimis interest) as consideration for the performance
of services to or for the benefit of the Operating Partnership (including the grant of a long-term incentive unit), and at such other times as may be desirable or required to comply with the Treasury Regulations.

During the years ended December 31, 2013, 2012 and 2011, certain employees and directors were granted an aggregate of 89,769, 79,237
and 85,910 long-term incentive units, respectively. During the years ended December 31, 2013, 2012 and 2011, certain employees were also granted an aggregate of 95,316, 86,843 and 98,632 long-term incentive units, respectively, which, in
addition to a service condition, are subject to a performance condition that impacts the number of units which ultimately vests. The performance condition is based upon our achievement of the respective fiscal years Core Funds From Operations,
or CFFO, per share targets. Upon evaluating the results of the performance condition, the final number of units is determined and such units vest based on satisfaction of the service conditions. The service conditions of the awards provide for 20%
vesting on each of the first and second anniversaries of the grant date and 30% vesting on each of the third and fourth anniversaries of the grant date, provided the grantee continues employment on each anniversary date. Based on our 2013, 2012 and
2011 CFFO per diluted share and unit, 75,105 of the 2013 long-term incentive units (net of forfeitures), 78,118 of the 2012 long-term incentive units (net of forfeitures) and all of the 2011 long-term incentive units, respectively, satisfied the
performance condition. The grant date fair values, which equal the market price of Digital Realty Trust, Inc. common stock, are being expensed on a straight-line basis for service awards over four years, the current vesting period of the long-term
incentive units. For performance based awards, we expense the fair value using an accelerated method with each vesting tranche valued as a separate award.

The expense recorded for the years ended December 31, 2013, 2012 and 2011 related to long-term incentive units was approximately $8.9 million, $9.0 million and $8.7 million, respectively. We
capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $1.6 million, $1.1 million and $0.8 million for the years ended December 31, 2013, 2012
and 2011, respectively. Unearned compensation representing the unvested portion of the long-term incentive units totaled $12.9 million and $13.3 million as of December 31, 2013 and 2012, respectively. We expect to recognize this unearned
compensation over the next 2.5 years on a weighted average basis.

(b) Class C Profits Interest Units

On May 2, 2007, we granted awards of Class C Profits Interest Units of the Operating Partnership or similar
stock-based performance awards, which we refer to collectively as the Class C Units, under the Amended and Restated 2004 Incentive Award Plan (2007 Grant) to each of our named executive officers and certain other officers and employees.

The Class C Units subject to this award were subject to vesting based on the achievement of a total stockholder return (which we refer to
as the market condition) as measured on November 1, 2008 (which we refer to as the first measurement date) and May 1, 2010 (which we refer to as the second measurement date).

We previously determined that the market condition with respect to the first measurement date was not achieved. On May 1, 2010, we
determined that 593,316 of the Class C Units and 20,169 shares of restricted stock

subject to the 2007 Grant satisfied the market condition on the second measurement date (May 1, 2010), with the value of these units equal to the maximum amount of the award pool payable pursuant
to the 2007 Grant on the second measurement date. Of the Class C Units that satisfied the market condition on May 1, 2010, 60% vested on May 1, 2010 and the remaining 40% vested ratably each month through April 30, 2012.

The fair value of the 2007 Grant was measured on the grant date using a Monte Carlo simulation to estimate the probability of the
multiple market conditions being satisfied. The Monte Carlo simulation uses a statistical formula underlying the Black-Scholes and binomial formulas, and such simulation was run approximately 100,000 times. For each simulation, the value of the
payoff was calculated at the settlement date and was then discounted to the grant date at a risk-free interest rate. The expected value of the Class C Units on the grant date was determined by multiplying the average of the values over all
simulations by the number of outstanding shares of Digital Realty Trust, Inc. common stock and Operating Partnership units. The valuation was performed in a risk-neutral framework, so no assumption was made with respect to an equity risk premium.
Other significant assumptions used in the valuation included an expected term of 36 months, expected stock price volatility of 23%, a risk-free interest rate of 4.6%, and a dividend growth rate of 5.0%. The fixed award limit under the plan was $17
million for the first market condition and $40 million for the second market condition, and there were 69.2 million shares of Digital Realty Trust, Inc. common stock and Operating Partnership units outstanding as of the 2007 Grant date. The
grant date fair value of these awards of approximately $11.8 million was recognized as compensation expense on a straight-line basis over the expected service period of five years, which ended during the three months ended June 30, 2012.

We recognized compensation expense related to the Class C Units subject to the 2007 Grant of $0.5 million and $2.0 million
for the years ended December 31, 2012 and 2011, respectively. We capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $0.1 million and $0.3
million for the years ended December 31, 2012 and 2011, respectively.

(c) Stock Options

The fair value of each option granted under the Amended and Restated 2004 Incentive Award Plan is estimated on the date of the grant using
the Black-Scholes option-pricing model. For the years ended December 31, 2013, 2012 and 2011, no stock options were granted. The fair values are being expensed on a straight-line basis over the vesting period of the options, which ranges from
four to five years. All unearned compensation has been recognized as of December 31, 2012. The expense recorded for the years ended December 31, 2012 and 2011 was approximately $0.2 million and $0.8 million, respectively. We capitalized
amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $0.1 million and $0.2 million for the years ended December 31, 2012 and 2011, respectively.

(d) Restricted Stock

During the years ended December 31, 2013, 2012 and 2011, certain employees were granted an aggregate of 79,114, 46,617 and 41,220
shares of restricted stock, respectively. During the years ended December 31, 2013, 2012 and 2011, certain employees were also granted an aggregate of 69,995, 52,947 and 50,999 shares of restricted stock, respectively, which, in addition to a
service condition, are subject to a performance condition that impacts the number of shares which ultimately vests. The performance condition is based upon our achievement of the respective years CFFO per share targets. Upon evaluating the
results of the performance condition, the final number of shares is determined and such shares vest based on satisfaction of the service conditions. The service conditions of the awards provide for 20% vesting on each of the first and second
anniversaries of the grant date and 30% vesting on each of the third and fourth anniversaries of the grant date provided the grantee continues employment on each anniversary date. Based on our 2013, 2012 and 2011 CFFO per diluted share and unit,
50,805 shares of the 2013 restricted stock awards (net of forfeitures), 49,325 shares of the 2012 restricted stock (net of forfeitures) and all of the 2011 restricted stock, respectively, satisfied the performance condition.

The grant date fair values, which equal the market price of Digital Realty Trust, Inc. common stock, are being expensed on a
straight-line basis for service awards over the vesting period of the restricted stock, which ranges from three to four years. For performance based awards, we expense the fair value using an accelerated method with each vesting tranche valued as a
separate award.

The expense recorded for the years ended December 31, 2013, 2012 and 2011 related
to grants of restricted stock was approximately $2.7 million, $2.9 million and $2.0 million, respectively. We capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities
of approximately $2.5 million, $2.1 million and $1.5 million for the years ended December 31, 2013, 2012 and 2011, respectively. Unearned compensation representing the unvested portion of the restricted stock totaled $8.7 million and $7.4
million as of December 31, 2013 and 2012, respectively. We expect to recognize this unearned compensation over the next 2.8 years on a weighted average basis.

(e) 401(k) Plan

We have a 401(k) plan whereby our employees may
contribute a portion of their compensation to their respective retirement accounts, in an amount not to exceed the maximum allowed under the Code. The 401(k) Plan complies with Internal Revenue Service requirements as a 401(k) Safe Harbor Plan
whereby discretionary contributions made by us are 100% vested. The aggregate cost of our contributions to the 401(k) Plan was approximately $2.4 million, $2.0 million, and $1.5 million for the years ended December 31, 2013, 2012 and 2011,
respectively.

14. Derivative Instruments

Currently, we use interest rate swaps to manage our interest rate risk. The valuation of these instruments is
determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses
observable market-based inputs, including interest rate curves. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted
expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves.

To comply with the provisions of fair value accounting guidance, we incorporate credit valuation adjustments to appropriately reflect
both our own nonperformance risk and the respective counterpartys nonperformance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we have considered the impact
of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.

Although we have determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value
hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by us and our counterparties. However, as of December 31,
2013, we have assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and have determined that the credit valuation adjustments are not significant to the overall valuation of
our derivatives. As a result, we have determined that our derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. We do not have any fair value measurements on a recurring basis using significant unobservable
inputs (Level 3) as of December 31, 2013 or December 31, 2012.

Cash Flow Hedges of Interest Rate Risk

Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposure
to interest rate movements related to US LIBOR, GBP LIBOR and EURIBOR based mortgage loans as

well as the U.S. LIBOR and SGD-SOR based tranches of the unsecured term loan. To accomplish this objective, we primarily use interest rate swaps as part of our interest rate risk management
strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional
amount.

We record all our interest rate swaps on the consolidated balance sheet at fair value. In determining the fair value
of our interest rate swaps, we consider the credit risk of our counterparties. These counterparties are generally larger financial institutions engaged in providing a variety of financial services. These institutions generally face similar risks
regarding adverse changes in market and economic conditions, including, but not limited to, fluctuations in interest rates, exchange rates, equity and commodity prices and credit spreads. The current and pervasive disruptions in the financial
markets have heightened the risks to these institutions.

Our agreements with some of our derivative counterparties provide
that (1) we could be declared in default on our derivative obligations if repayment of any of our indebtedness over $75.0 million is accelerated by the lender due to our default on the indebtedness and (2) we could be declared in default
on a certain derivative obligation if we default on any of our indebtedness, including a default where repayment of underlying indebtedness has not been accelerated by the lender.

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in
accumulated other comprehensive income (loss) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During 2013, such derivatives were used to hedge the variable cash flows associated
with existing variable-rate debt. The fair value of these derivatives was $0.1 million and ($8.7) million at December 31, 2013 and December 31, 2012, respectively. The ineffective portion of the change in fair value of the derivatives is
recognized directly in earnings. During the years ended December 31, 2013, 2012 and 2011, there were no ineffective portions to our interest rate swaps.

Amounts reported in accumulated other comprehensive loss related to interest rate swaps will be reclassified to interest expense as interest payments are made on our debt. As of December 31, 2013, we
estimate that an additional $3.1 million will be reclassified as an increase to interest expense during the year ending December 31, 2014, when the hedged forecasted transactions impact earnings.

As of December 31, 2013 and December 31, 2012, we had the following outstanding interest rate derivatives that were designated
as cash flow hedges of interest rate risk (in thousands):

15. Fair Value of Instruments

We disclose fair value information about all financial instruments, whether or not recognized in the consolidated
balance sheets, for which it is practicable to estimate fair value. Current accounting guidance requires the Company to disclose fair value information about all financial instruments, whether or not recognized in the balance sheets, for which it is
practicable to estimate fair value.

The Companys disclosures of estimated fair value of financial instruments at
December 31, 2013 and December 31, 2012 were determined using available market information and appropriate valuation methods. Considerable judgment is necessary to interpret market data and develop estimated fair value. The use of
different market assumptions or estimation methods may have a material effect on the estimated fair value amounts.

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. As described in note 14, the interest rate swaps are recorded at fair value.

We calculate the fair value of our mortgage loans, unsecured term loan, unsecured senior notes and exchangeable senior debentures 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 debt. The carrying value of our global revolving credit facility approximates fair value, due to the variability of interest rates.

As of December 31, 2013 and December 31, 2012, the aggregate estimated fair value and carrying value of our global revolving
credit facility, unsecured term loan, unsecured senior notes, exchangeable senior debentures and mortgage loans were as follows (in thousands):

17. Related Party Transactions

In December 2006, we entered into ten leases with tel(x) pursuant to which tel(x) provides enhanced meet-me-room
services to our customers. The initial terms of these leases expire in 2026, and tel(x) has options to extend them through 2046. tel(x) was acquired by GI Partners Fund II, LLP in November 2006, which, collectively with GI Partners Side Fund II,
L.P., owned the majority of the outstanding stock of tel(x). Richard Magnuson, our former director and Chairman who served until our 2012 Annual Meeting of Stockholders, or the Annual Meeting, is the chief executive officer of the advisor to GI
Partners Fund II, LLP and GI Partners Side Fund II, L.P. During the year ended December 31, 2011, GI Partners Fund II, LLP and GI Partners Side Fund II,

L.P completed the sale of tel(x) to an unrelated third party. Our consolidated statements of operations include rental revenues of approximately $48.6 million, $45.7 million and $42.5 million
from tel(x) for the years ended December 31, 2013, 2012 and 2011, respectively, from leases entered into before tel(x) was sold to an unrelated third party. In connection with the lease agreements, we entered into an operating agreement with
tel(x), effective as of December 1, 2006, with respect to joint sales and marketing efforts, designation of representatives to manage the national relationship between us and tel(x) and future meet-me-room facilities. As of December 31,
2013 and 2012, tel(x) leased from us 341,202 square feet under 55 lease agreements and 288,940 square feet under 44 lease agreements, respectively; all but 14 leases for 86,888 square feet were entered into prior to the sale of tel(x) to an
unrelated third party in September 2011.

We also entered into an agreement with tel(x), effective as of December 1,
2006, with respect to percentage rent arising out of potential future lease agreements for rentable space in buildings covered by the meet-me-room lease agreements. Percentage rent earned during the years ended December 31, 2013, 2012 and 2011
amounted to approximately $6.0 million, $4.8 million and $3.6 million, respectively. In addition, in connection with the lease agreements, we entered into a management agreement with tel(x), effective as of December 1, 2007, pursuant to which
tel(x) agreed to provide us with certain management services in exchange for a management fee of one percent of rents actually collected by tel(x).

Prior to the 2012 Annual Meeting, we had entered into nine leases with SoftLayer, all of which are in place as of December 31, 2013. The initial terms of these leases expire from 2013 to 2025, and
SoftLayer has options to extend them from 2018 through 2035. On August 3, 2010, GI Partners Fund III, L.P. acquired a controlling interest in SoftLayer. Richard Magnuson, our former director and Chairman who served until our Annual Meeting, is
also a manager of the general partner to GI Partners Fund III, L.P. Our consolidated statements of operations include rental revenues of approximately $53.9 million, $48.3 million and $20.2 million from SoftLayer for the years ended
December 31, 2013, 2012 and 2011, respectively, from leases entered into before Mr. Magnusons term as a member of our Board of Directors and our Chairman ended. In July 2013, SoftLayer was acquired by IBM.

Mr. Magnuson did not stand for re-election to our Board of Directors at our Annual Meeting. His term as a member of our Board of
Directors and our Chairman ended effective April 23, 2012, the date of the Annual Meeting.

18. Commitments and Contingencies

(a) Operating Leases

We have a ground lease obligation on 2010 East Centennial Circle that expires in 2082. After February 2036, rent for the remaining term of the 2010 East Centennial Circle ground lease will be determined
based on a fair market value appraisal of the property and, as result, rent after February 2036 is excluded from the minimum commitment information below.

We have ground leases on Paul van Vlissingenstraat 16 that expires in 2054, Chemin de lEpinglier 2 that expires in 2074, Clonshaugh Industrial Estate I and II that expires in 2981, Manchester
Technopark that expires in 2125, 29A International Business Park that expires in 2038, Gyroscoopweg 2E-2F, which has a continuous ground lease and will be adjusted on January 1, 2042, and Naritaweg 52, which has a continuous ground lease. In
late 2011, we executed a lease for a new location for our headquarters, which began in May 2012, with a lease term of 12 years with an option to extend the lease for an additional five years. We also have operating leases at 111 8thAvenue (2ndand 6thfloors), 8100 Boone Boulevard, 111 8thAvenue (3rdand 7thfloors) and 410 Commerce Boulevard, which expire in June 2024, September 2017, February 2022 and December
2026, respectively. The

lease at 111 8thAvenue (2ndand 6thfloors) has an option to extend the lease until
June 2034 and the lease at 111 8thAvenue (3rdand 7thfloors) has an option to extend the lease until February 2032. The leases at 8100 Boone Boulevard and 410 Commerce
Boulevard have no extension options.

We have a fully prepaid ground lease on 2055 E. Technology Circle that expires in 2083.
We have a fully prepaid ground lease on Cateringweg 5 that expires in 2059. The ground lease at Naritaweg 52 has been prepaid through December 2036.

Rental expense for these leases was approximately $23.1 million, $10.2 million, and $8.5 million for the years ended December 31, 2013, 2012 and 2011 respectively. In 2013, a non-cash $10.0 million
straight-line rent expense adjustment was recorded in rental property operating and maintenance expenses related to a lease amendment executed in September 2010, $7.5 million of this amount related to prior years. This adjustment was deemed to be
immaterial to both the current year and prior year financial statements taken as a whole.

The minimum commitment under these
leases, excluding the fully prepaid ground leases, as of December 31, 2013 was as follows (in thousands):



|           |  |   |         | 
|---------- |  | - | ------- |

|Total      |  | $ | 182,769 | 
|           |  |   |         | 

(b) Contingent liabilities

As part of the acquisition of 29A International Business Park, the seller could earn additional consideration based on future net
operating income growth in excess of certain performance targets, as defined. As of December 31, 2013, construction is not complete and none of the leases executed subsequent to purchase would cause an amount to become probable of payment and
therefore no amount is accrued as of December 31, 2013. The maximum amount that could be earned by the seller is $50.0 million SGD (or approximately $39.6 million based on the exchange rate as of December 31, 2013). The earnout contingency
expires in November 2020.

One of the tenants at our Convergence Business Park property has an option to expand as part of
their lease agreement, which expires in April 2017. As part of this option, development activities are not permitted on specifically identified expansion space within the property until April 2014. If the tenant elects to take this option,
we can elect one of two options. The first option is to construct and develop an additional shell building on the expansion space. Concurrent with this obligation, the tenant would execute an amendment to the existing lease to reflect the
expansion of the space and include the additional shell building. The second option is to sell the existing building and the expansion space to the tenant for a price of approximately $24.0 million and $225,000 per square acre, respectively, plus
additional adjustments as provided in the lease.

As part of the acquisition of the Sentrum Portfolio, the seller could earn
additional consideration based on future net returns on vacant space to be developed, but not currently leased, as defined in the purchase agreement for the acquisition. The initial estimate of fair value of contingent consideration was
approximately £56.5 million

(or approximately $87.6 million based on the exchange rate as of July 11, 2012, the acquisition date). During the year ended December 31, 2013, we made certain immaterial corrections to
the initial measurement of the accrued contingent consideration that resulted in an additional $5.8 million of purchase price allocated to investments in real estate. These corrections had no material impact on reported net income for the period. We
have adjusted the contingent consideration to fair value at each reporting date with changes in fair value recognized in operating income. At December 31, 2013, the fair value of the contingent consideration for Sentrum was
£39.2 million (or approximately $64.9 million based on the exchange rate as of December 31, 2013) and is currently accrued in accounts payable and other accrued expenses in the consolidated balance sheet. During the year ended
December 31, 2013, we have made earnout payments of approximately £16.9 million (or approximately $25.8 million based on the exchange rates as of the date of each payment). Change in fair value of contingent consideration for
Sentrum was an increase to operating income of approximately $1.8 million and $1.1 million for the years ended December 31, 2013 and 2012, respectively. The earn-out contingency expires in July 2015. This amount will be reassessed on a
quarterly basis, with any changes being recognized in earnings. Increases or decreases in the fair value of the contingent consideration can result from changes in discount periods, discount rates and probabilities that contingencies will be met.

(c) Construction Commitments

Our properties require periodic investments of capital for tenant-related capital expenditures and for general capital improvements and 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 December 31, 2013, we had open commitments related to construction contracts of approximately $202.1 million.

(d) Legal Proceedings

Although the Company is involved in legal proceedings arising in the ordinary course of business, as of December 31, 2013, the Company is not currently a party to any legal proceedings nor, to its
knowledge, is any legal proceeding threatened against it that it believes would have a material adverse effect on its financial position, results of operations or liquidity.

|ITEM 9. | CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE
|------- | ------------------------------------------------------------------------------------

Not Applicable.



|ITEM 9A. | CONTROLS AND PROCEDURES
|-------- | -----------------------

Our Managements Report on Internal Control over Financial Reporting for Digital Realty Trust, Inc. and Digital Realty Trust, L.P. are included in Part II, Item 8, Financial Statements and
Supplementary Data on pages 95 and 96.

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, 2013. Based on the foregoing, the companys management concluded that its disclosure controls and procedures were effective at the reasonable assurance level.

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

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.
