EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the quarter ended September 30, 2025 of Digital Realty Trust, Inc., a Maryland corporation, and Digital Realty Trust, L.P., a Maryland limited partnership, of which Digital Realty Trust, Inc. is the sole general partner. Unless otherwise indicated or unless the context requires otherwise, all references in this report to “we,” “us,” “our,” “our Company,” or “the Company” refer to Digital Realty Trust, Inc. together with its consolidated subsidiaries, including Digital Realty Trust, L.P. In statements regarding qualification as a REIT, such terms refer solely to Digital Realty Trust, Inc. Unless otherwise indicated or unless the context requires otherwise, all references to the “Parent” refer to Digital Realty Trust, Inc., and all references to “our Operating Partnership,” “the Operating Partnership” or “the OP” refer to Digital Realty Trust, L.P. together with its consolidated subsidiaries.

The Parent is a real estate investment trust, or REIT, for U.S. federal income tax purposes and the sole general partner of the OP. As of September 30, 2025, the Parent owned an approximate 98.2% common general partnership interest in Digital Realty Trust, L.P. The remaining approximate 1.8% of the common limited partnership interests of Digital Realty Trust, L.P. are owned by non-affiliated third parties and certain directors and officers of the Parent. As of September 30, 2025, the Parent owned all of the preferred limited partnership interests of Digital Realty Trust, L.P. As the sole general partner of Digital Realty Trust, L.P., the Parent has the full, exclusive and complete responsibility for the OP’s day-to-day management and control.

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

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

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

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

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

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

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

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

1. General

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

​

The Parent’s only material asset is its ownership of partnership interests of the OP. The Parent generally does not conduct business itself, other than acting as the sole general partner of the OP, issuing public securities from time to time and guaranteeing certain unsecured debt of the OP and certain of its subsidiaries and affiliates. The Parent has not issued any debt but guarantees the unsecured debt of the OP and certain of its subsidiaries and affiliates.

​

The OP holds substantially all the assets of the Company. The OP conducts the operations of the business and has no publicly traded equity. Except for net proceeds from public equity issuances by the Parent, which are generally contributed to the OP in exchange for partnership units, the OP generally generates capital required by the Company’s business primarily through the OP’s operations, by the OP’s or its affiliates’ direct or indirect incurrence of indebtedness or through the issuance of partnership units.

​

Accounting Principles and Basis of Presentation. The accompanying unaudited interim condensed consolidated financial statements and accompanying notes (the “Financial Statements”) are prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and are presented in our reporting currency, the U.S. dollar. All of the accounts of the Parent, the OP, and the subsidiaries of the OP are included in the accompanying Financial Statements. All material intercompany transactions with consolidated entities have been eliminated. In the opinion of management, the unaudited interim consolidated financial statements reflect all adjustments of a normal recurring nature that are necessary for a fair statement of the results for the interim periods presented. Interim results are not always indicative of results for a full year. The information included in this Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2024 (“2024 Form 10-K”), as filed with the U.S. Securities and Exchange Commission (“SEC”), our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2025 and June 30, 2025, as filed with the SEC, and our other filings with the SEC.

​

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

​

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

2. Investments in Properties

​

A summary of our investments in properties is below (in thousands):

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Property Type | ​ | As of September 30, 2025 | ​ | ​ | As of December 31, 2024

Investments in properties, net | ​ | $ | 26,018,517 | ​ | ​ | $ | 24,120,782

​

Acquisitions

​

During the quarter, we closed on acquisitions of land parcels for approximately $67 million in the aggregate.

Contributions

​

During the first half of 2025, the Company launched its first U.S. Hyperscale Data Center Fund (the “Fund”), successfully raising more than $3 billion of equity commitments to date. Fund commitments represent a 40% to 80% ownership interest in each individual asset, while the Company will maintain the remaining 20% to 60% stake in the assets and less than a 2% direct interest in the Fund. The initial portfolio includes five operating data centers plus three land sites with access to power for data center development. In May 2025, we received approximately $937 million of gross proceeds from the contribution of operating data centers and development projects to the Fund, recognized a gain on disposition of approximately $873 million, and recognized an investment in the assets of $661 million. The Company will serve as general partner, maintaining operational and management responsibilities for the assets, however, certain governance rights are granted to the limited partners. As such, we concluded we do not own a controlling interest and account for our interest in the assets under the equity method of accounting. These real estate assets were previously classified as held for sale and contribution. Additionally, as of September 30, 2025, one additional development project was classified within Assets held for sale and contribution on our condensed consolidated balance sheet as it is probable it will be contributed to the Fund within one year. The disposition of a portion of our interest in the remaining development project met the criteria under ASC 360 for the assets to qualify as held for sale and contribution. However, the operations are not classified as discontinued operations as a result of our continuing interest in the assets. This development project was not representative of a significant component of our portfolio, nor will the contribution represent a significant shift in our strategy.

​

On April 3, 2025, we received approximately $77 million of gross proceeds from the contribution of our data centers to the joint venture with Blackstone. As a result of transferring control, we derecognized the data centers and recognized a gain on disposition of approximately $58 million.

​

As of September 30, 2025, real estate assets, including those mentioned above, that qualified as held for sale had an aggregate carrying value of $116.6 million within total assets and $0.3 million within total liabilities and are shown within Assets held for sale and contribution and Obligations associated with assets held for sale and contribution, respectively, on the condensed consolidated balance sheets. Subsequent to quarter end, Digital Realty sold a non-core

data center in the Dallas metro area, which was held for sale as of September 30, 2025, for gross proceeds of $33 million.

​

3. Leases

Lessor Accounting

We generate most of our revenue by leasing operating properties to customers under operating lease agreements. We recognize the total minimum lease payments provided for under the leases on a straight-line basis over the lease term if we determine that it is probable that substantially all of the lease payments will be collected over the lease term. Otherwise, rental revenue is recognized based on the amount contractually due. Generally, under the terms of our leases, some of our rental expenses, including common area maintenance, real estate taxes and insurance, are recovered from our customers. We record amounts reimbursed by customers in the period the applicable expenses are incurred, which is generally ratably throughout the term of the lease. Reimbursements are recognized in rental and other services revenue in the condensed consolidated income statements as we are the primary obligor with respect to purchasing and selecting goods and services from third-party vendors and bearing the associated credit risk. Our largest customer’s total revenue approximates 12% of our total revenue base. No other individual customer makes up more than 10% of our total revenue.

Lessee Accounting

​

We lease space at certain of our data centers from third parties and certain equipment under noncancelable lease agreements. Leases for our data centers expire at various dates through 2069. As of September 30, 2025, certain of our data centers, primarily in Europe and Singapore, are subject to ground leases. As of September 30, 2025, the termination dates of these ground leases generally range from 2038 to 2073. In addition, our corporate headquarters along with several regional office locations are subject to leases with termination dates ranging from 2026 to 2037.

​

The leases generally require us to make fixed rental payments that increase at defined intervals during the term of the lease, plus pay our share of common area, real estate and utility expenses as incurred. The leases neither contain residual value guarantees nor impose material restrictions or covenants on us. Further, the leases have been classified and accounted for as either operating or finance leases. Rent expense related to operating leases included in rental property operating and maintenance expense in the condensed consolidated income statements amounted to approximately $40.5 million and $39.2 million for the three months ended September 30, 2025 and 2024, respectively, and approximately $118.8 million and $112.6 million for the nine months ended September 30, 2025 and 2024, respectively.

​

Deferred Rent, Net

​

Deferred rent, net represents rental income that has been recognized as revenue under ASC 842, but which is not yet due from customers under their existing rental agreements. The Company recognizes an allowance against deferred rent receivables to the extent it becomes no longer probable that a customer or group of customers will be able to make substantially all of their required cash rental payments over the entirety of their respective lease terms.

5. Investments in Unconsolidated Entities

A summary of the Company’s investments in unconsolidated entities accounted for under the equity method of accounting is shown below (in thousands):

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Balance as of | ​ | Balance as of
​ | ​ | ​ | September 30, 2025 | ​ | ​ | December 31, 2024
Americas (1) | ​ | $ | 2,270,335 | ​ | $ | 1,311,950
APAC (2) | ​ | ​ | 723,335 | ​ | ​ | 615,687
EMEA (3) | ​ | ​ | 240,724 | ​ | ​ | 252,791
Global (4) | ​ | ​ | 456,355 | ​ | ​ | 459,372
Total | ​ | $ | 3,690,749 | ​ | $ | 2,639,800

Includes the following unconsolidated entities along with our ownership percentage as of September 30, 2025:

(1) | Ascenty (49%), Blackstone (ranging from 20% to 50%), Clise (50%), GI Partners (ranging from 20% to 25%), Mapletree (20%), Menlo (20%), Mitsubishi (20%), Realty Income (20%), TPG Real Estate (20%), Fund (ranging from 20% to 60%), and Walsh (88%).

(2) | Digital Connexion (33%), Digital Realty Bersama (50%), Lumen (50%), and MC Digital Realty (50%).

(3) | Blackstone (20%), Medallion (60%), and Mivne (50%).

(4) | Digital Core REIT (39%).

​

Generally, we serve as the managing member responsible for operations in the ordinary course of business of the unconsolidated entities. We perform the day-to-day accounting and property management functions for the unconsolidated entities and, as such, will earn management fees. In certain unconsolidated entities, we may also earn incentive fees upon liquidation of individual unconsolidated entities’ assets based primarily on the total return of the investments over certain financial hurdles. The incentive fee and financial hurdle vary by each entity. However, certain approval rights are granted through the terms of the operating agreements and require unanimous consent of both members with respect to any major decisions. Generally, major decisions are defined to include the annual plan which sets out unconsolidated entity and property level budgets, including lease revenues, operating expenses, and capital expenditures. As such, we concluded we do not own a controlling interest and accounted for our interest in the unconsolidated entities under the equity method of accounting.

​

U.S. Hyperscale Data Center Fund – During the first half of 2025, the Company launched the Fund, successfully raising more than $3 billion of equity commitments to date. Fund commitments represent a 40% to 80% ownership interest in each individual asset, while the Company will maintain the remaining 20% to 60% stake in the assets and less than a 2% direct interest in the Fund. The initial portfolio includes five operating data centers plus three land sites with access to power for data center development. In May 2025, we received approximately $937 million of gross proceeds from the contribution of operating data centers and development projects to the Fund, recognized a gain on disposition of approximately $873 million, and recognized an investment in the assets of $661 million.

​

Blackstone Joint Ventures – On January 11, 2024, we formed joint ventures with Blackstone Inc. to develop four hyperscale data center campuses across Frankfurt, Paris and Northern Virginia. The first phase of the joint venture closed on hyperscale data center campuses in Paris and Northern Virginia, and we retained a 20% interest in the joint venture from the contribution of our data centers. In the fourth quarter of 2024, the second phase of the joint venture closed on a hyperscale data center campus in Frankfurt and at Digital Dulles campus in Northern Virginia. We retained a 20% interest in the joint venture from the contribution of our data centers. On April 3, 2025, we contributed an additional three development projects at Digital Dulles campus to the joint venture with Blackstone. We received approximately $77 million of gross proceeds from the contribution and as a result of transferring control, we derecognized the data centers and recognized a gain on disposition of approximately $58 million. In connection with the April transaction, we maintained a 50% interest in all four Blackstone joint venture properties at Digital Dulles campus.

​

Digital Realty Bersama Joint Venture – On March 18, 2025, we formed a joint venture with Bersama Digital Infrastructure Asia (BDIA) to develop and operate data centers across Indonesia. We acquired a 50% interest in the joint venture, which consists of two land parcels and two buildings in Jakarta, Indonesia for approximately $94.7 million. The 6 acres of land and two buildings can support up to approximately 32 megawatts of IT load.

​

Mitsubishi Joint Venture - On March 1, 2024, we formed a joint venture with Mitsubishi Corporation, or Mitsubishi, to support the development of two data centers in the Dallas metro area. We retained a 35% interest in the joint venture. Each partner funded its pro rata share of the remaining $140 million estimated development cost for the first phase of the project, of which one project was completed in June 2024 and another was completed in October 2024. On January 31, 2025, Mitsubishi made an additional cash capital contribution in the amount of $62 million, resulting in an additional 15% ownership in the joint venture. The transaction resulted in a gain of approximately $5.1 million. Currently, Mitsubishi has an 80% interest in the joint venture, and we have retained a 20% interest.

​

DCREIT – Digital Core REIT is a standalone real estate investment trust formed under Singapore law, which is publicly traded on the Singapore Exchange under the ticker symbol “DCRU”. DCREIT owns 10 operating data center properties. The Company has ownership interest in the units of DCREIT, as well as ownership interests in the operating properties of DCREIT.

​

As of September 30, 2025, the Company held 32% of the outstanding DCREIT units and separately owned a 10% direct retained interest in the underlying North American operating properties and a 35% direct retained interest in a Frankfurt asset.

​

The Company’s 32% interest in DCREIT consisted of 420 million units and 418 million units as of September 30, 2025 and December 31, 2024, respectively. Based on the closing price per unit of $0.48 and $0.58 as of September 30, 2025 and December 31, 2024, respectively, the fair value of the units the Company owned in DCREIT was approximately $202 million and $242 million as of September 30, 2025 and December 31, 2024, respectively.

​

Pursuant to contractual agreements with DCREIT and its operating properties, the Company will earn fees for asset and property management services as well as fees for aiding in future acquisition, disposition and development activities. Certain of these fees are payable to the Company in the form of additional units in DCREIT or in cash. The Company earned fees pursuant to these contractual agreements of approximately $2.7 million and $0.8 million for the three months ended September 30, 2025 and 2024, respectively, and $8.9 million and $6.8 million for the nine months ended September 30, 2025 and 2024, respectively, which are recorded as fee income and other on the condensed consolidated income statements.

​

Ascenty – In addition to the Company’s 49% ownership interest in Ascenty, there is also an approximate 2% interest held by one of the Company’s noncontrolling interest holders. This 2% interest had a carrying value of approximately $23 million as of September 30, 2025 and December 31, 2024. Ascenty is a variable interest entity (“VIE”) and the Company’s maximum exposure to loss related to this VIE is limited to our equity investment in the entity.

​

Debt – The debt of our unconsolidated entities generally is non-recourse to us, except for customary exceptions pertaining to matters such as intentional misuse of funds, environmental conditions, and material misrepresentations.

​

6. Goodwill

Goodwill represents the excess of the purchase price over the fair value of net tangible and intangible assets acquired in a business combination. Changes in the value of goodwill at September 30, 2025 as compared to December 31, 2024 were driven by changes in exchange rates associated with goodwill balances denominated in foreign currencies.

​

We primarily borrow in the functional currencies of the countries where we invest. Included in the outstanding balances were borrowings denominated in the following currencies (in thousands, U.S. dollars):

​

On September 24, 2024, we refinanced our Global Revolving Credit Facilities. Below are key terms for our Global Revolving Credit Facility and Yen Revolving Credit Facility.

​

Global Revolving Credit Facility

​

We have a Global Revolving Credit Facility under which we may draw up to $4.2 billion equivalent on a revolving basis (subject to currency fluctuations). The Global Revolving Credit Facility can be drawn in Australian dollars, British pound sterling, Canadian dollars, Euros, Hong Kong dollars, Indonesian rupiah, Japanese yen, Korean won, Singapore dollars, Swiss francs and U.S. dollars (with the ability to add other currencies in the future). As of September 30, 2025, approximately $97.4 million of letters of credit were issued.

​

We have the ability to increase the size of the Global Revolving Credit Facility by up to $1.8 billion, subject to the receipt of lender commitments and the satisfaction of certain customary conditions precedent. Other key terms of the Global Revolving Credit Facility are as follows:

​

| ● | Maturity date: January 24, 2029, with two six-month extension options available. The bank group is obligated to grant the extension options provided we give proper notice, we make certain representations and warranties and no default exists under the Global Revolving Credit Facilities.

| ● | Interest rate: the applicable index plus a margin which is based on the credit ratings of our long-term debt and is currently 77.5 basis points (subject to a sustainability-linked pricing component).

| ● | Annual facility fee: based on the total commitment amount of the facility and the credit ratings of our long-term debt is currently 15 basis points (subject to a sustainability-linked pricing component) and is payable quarterly.

​

| ● | Sustainability-linked pricing component: pricing can increase by up to 5 basis points or decrease by up to 5 basis points depending on whether or not the OP or its subsidiaries meet certain sustainability performance targets.

Yen Revolving Credit Facility

​

In addition to the Global Revolving Credit Facility, we have a revolving credit facility that provides for borrowings in Japanese yen of up to ¥42.5 billion (approximately $287.4 million based on the exchange rate on September 30, 2025), hereafter referred to as the “Yen Revolving Credit Facility”. We have the ability from time to time to increase the size of the Yen Revolving Credit Facility to up to ¥102.5 billion, subject to receipt of lender commitments and other conditions precedent. Other key terms of the Yen Revolving Credit Facility are as follows:

​

| ● | Maturity date: January 24, 2029, with two six-month extension options available. The bank group is obligated to grant the extension options provided we give proper notice, we make certain representations and warranties and no default exists under the Global Revolving Credit Facilities.

| ● | Quarterly unused commitment fee: currently is 10 basis points (subject to a sustainability-linked pricing component), calculated using the average daily unused revolving credit commitment and is based on the credit ratings of our long-term debt.

| ● | Sustainability-linked pricing component: pricing can increase by up to 5 basis points or decrease by up to 5 basis points depending on whether or not the OP or its subsidiaries meet certain sustainability performance targets.

Restrictive Covenants in Global Revolving Credit Facility and Yen Revolving Credit Facility

​

The Global Revolving Credit Facility and the Yen Revolving Credit Facility both contain various restrictive covenants, including limitations on our ability to incur additional indebtedness, make certain investments, or merge with another company. In addition, we are required to maintain financial coverage ratios, including with respect to unencumbered assets. After the occurrence of and during the continuance of any event of default, these credit facilities restrict the Parent’s ability to make distributions to stockholders or redeem or otherwise repurchase shares of its capital stock, except in limited circumstances (such as those 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 September 30, 2025, we were in compliance with all of such covenants for both of these revolving credit facilities.

(1) | As part of the acquisition of Teraco in 2022, certain of Teraco's minority indirect shareholders (“Rollover Shareholders”) have the right to put their shares in an upstream parent company of Teraco (“Remaining Interest”) to the Company in exchange for cash or the equivalent value of shares of the Company common stock, or a combination thereof. Under U.S. GAAP, diluted earnings per share must be reflected in a manner that assumes such put right was exercised at the beginning of the respective periods and settled entirely in shares. The amounts shown represent the redemption value of the Remaining Interest of Teraco divided by Digital Realty Trust, Inc.’s average share price for the respective periods. The put right is exercisable by the Rollover Shareholders for a two-year period commencing on February 1, 2026.

​

In November 2024, Digital Realty Trust, L.P. issued $1,150,000,000 principal amount of its 1.875% Exchangeable Senior Notes due 2029 (the “Exchangeable Notes”). Net proceeds from the offering were approximately $1.1 billion after deducting managers’ discounts and offering expenses. As of September 30, 2025, the holders of the Exchangeable Notes will have an option on or after August 15, 2029, or at an earlier date under certain circumstances, to exchange the notes. The Company must always cash settle the principal amount of the Exchangeable Notes, while any excess may be settled via cash, common shares or a combination at the election of the Company. Accordingly, the Company applies the if converted method to determine the dilutive impact on EPS related to the Exchangeable Notes. There is no interest expense adjustment to the numerator as the principal will always be cash settled. In order to compute the dilutive effect, the number of shares included in the denominator of diluted EPS is determined by dividing the “conversion spread value” of the share-settled portion (value above principal and interest component) of the instrument by the average share price during the period. The “conversion spread value” is the value that would be delivered to the holders in shares based on the terms of the Exchangeable Notes upon an assumed conversion. As of September 30, 2025, the conversion spread value is currently zero, since the weighted average price of our common stock does not exceed the conversion rate (strike price) and is “out-of-the-money”, resulting in no impact on diluted EPS.

Equity Distribution Agreement

Digital Realty Trust, Inc. and Digital Realty Trust, L.P. are parties to an ATM Equity OfferingSM Sales Agreement dated December 23, 2024 (the “2024 Sales Agreement”). Pursuant to the 2024 Sales Agreement, Digital Realty Trust, Inc. can issue and sell common stock having an aggregate offering price of up to $3.0 billion through various named agents from time to time.

Since June 30, 2025, Digital Realty Trust, Inc. generated net proceeds of approximately $501 million from the issuance of approximately 2.9 million common shares under the 2024 Sales Agreement at an average price of $172.46 per share after payment of approximately $2.9 million of commissions to the agents.

The sales of common stock made under the 2024 Sales Agreement will be made in “at the market” offerings as defined in Rule 415 of the Securities Act. Our Parent has used and intends to use the net proceeds from the program to temporarily repay borrowings under our Operating Partnership’s Global Revolving Credit Facilities, to acquire additional properties or businesses, to fund development opportunities and for working capital and other general corporate purposes, including potentially for the repayment of other debt or the repurchase, redemption or retirement of outstanding debt securities.

Limited partners have the right to require the Operating Partnership to redeem all or a portion of their common units for cash based on the fair market value of an equivalent number of shares of Digital Realty Trust, Inc. common stock at the time of redemption. Alternatively, Digital Realty Trust, Inc. may elect to acquire those common units in exchange for shares of its common stock on a one-for-one basis, subject to adjustment in the event of stock splits, stock dividends, issuance of stock rights, specified extraordinary distributions and similar events. The common units and incentive units of the Operating Partnership are classified within equity, except for certain common units issued to certain former DuPont Fabros Technology, L.P. unitholders in the Company’s acquisition of DuPont Fabros Technology, Inc., which are subject to certain restrictions and, accordingly, are not presented as permanent equity in the condensed balance sheets.

​

The redemption value of the noncontrolling Operating Partnership common units and the vested incentive units was approximately $1,065.7 million and $1,090.4 million based on the closing market price of Digital Realty Trust, Inc. common stock on September 30, 2025 and December 31, 2024, respectively.

12. Incentive Plans

2014 Incentive Award Plan

The Company provides incentive awards in the form of common stock or awards convertible into common stock pursuant to the Digital Realty Trust, Inc., Digital Services, Inc. and Digital Realty Trust, L.P. 2014 Incentive Award Plan, as amended (the “Incentive Plan”). The major categories of awards that have been issued under the Incentive Plan include:

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

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

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

Market-Based Performance Awards.

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

Vesting with respect to the market condition is measured based on the difference between Digital Realty Trust, Inc.’s TSR percentage and the TSR percentage of the RMS as is shown in the subsequent table (the “RMS Relative Market Performance”).

​

​ | ​ | ​ | ​ | ​
​ | ​ | ​ | Market
​ | ​ | ​ | Performance
​ | RMS Relative | ​ | Vesting
Level | Market Performance | ​ | Percentage
Below Threshold Level | ≤ -500 basis points | ​ | 0 | %
Threshold Level | -500 basis points | ​ | 25 | %
Target Level | 0 basis points | ​ | 50 | %
High Level | ≥ 500 basis points | ​ | 100 | %

​

If the RMS Relative Market Performance falls between the levels specified in the above table, the percentage of the award that will vest with respect to the market condition will be determined using straight-line linear interpolation between such levels.

​

2022 Awards

| ● | In January 2025, the RMS Relative Market Performance was achieved at the high level of performance for the 2022 awards and, accordingly, 61,661 Class D units and 5,654 Restricted Stock Units performance vested and qualified for time-based vesting.

| ● | The Class D units included 6,997 distribution equivalent units that immediately vested on December 31, 2024.

| ● | On February 27, 2025, 50% of the 2022 awards vested and the remaining 50% will vest on February 27, 2026, subject to continued employment through the vesting date. ​ ​

​

The grant date fair value of the Market-Based Performance Awards was approximately $12.3 million and $9.8 million for the nine months ended September 30, 2025 and 2024, respectively. This amount will be recognized as compensation expense on a straight-line basis over the expected service period of approximately four years.

Financial-Based Performance Awards.

​

On January 1, 2025, the Company granted Financial-Based Performance Awards, which vest based on growth in same-store cash net operating income during the three-year period commencing on January 1, 2025. The awards have a time-based vesting element consistent with the Market-Based Performance Awards discussed above. For these awards, fair value is based on market value on the date of grant and compensation cost is recognized based on the probable achievement of the performance condition at each reporting period. The grant date fair value of these awards was $12.3 million, based on Digital Realty Trust, Inc.’s closing stock price at the grant date.

​

As of September 30, 2025, approximately 3.0 million shares of common stock, including awards that can be converted to or exchanged for shares of common stock, remained available for future issuance under the Incentive Plan.

Each LTIP unit and each Class D unit issued under the Incentive Plan counts as one share of common stock for purposes of calculating the limit on shares that may be issued under the Incentive Plan and the individual award limits set forth therein.

2025 Carried Interest Plan

On August 27, 2025, the Board of Directors (the “Board”) of the Parent approved the Digital Realty 2025 Carried Interest Plan (the “Carried Interest Plan”), pursuant to which certain employees of the Company, including our named executive officers, will be eligible to receive certain awards with respect to certain strategic capital ventures of the Company (each, a “Vehicle”). The purpose of the Carried Interest Plan is to attract, retain and incentivize certain executives and other employees of the Company in connection with, and to recognize the success of, such investments.

Types of Awards. The Carried Interest Plan provides for the grant of carried interest awards and appreciation interest awards.

| ● | Carried Interest Awards. Awards of carried interests under the Carried Interest Plan consist of interests in one or more Vehicles (a “carry vehicle”) holding the right to receive a portion of the carried interest or promote distributions generated from each of the Vehicles. When a carry vehicle receives, directly or indirectly, a distribution of the carried interest or promote (a “Carried Interest Payment Date”), the carry vehicle will distribute the net proceeds to participants holding fully vested carried interest awards in accordance with the Carried Interest Plan and applicable award agreement. The carried interest awards are intended to be treated as “profits interests” for U.S. federal income tax purposes.

| ● | Appreciation Interest Awards. Awards of appreciation interests are notional interests granted under the Carried Interest Plan that track the value of a corresponding carried interest award.

Vesting. Awards under the Plan will vest in full upon the satisfaction of both a service condition and a performance condition.

The service condition will be satisfied with respect to 25% of an award on each of the first four anniversaries of the applicable vesting commencement date, subject to the participant’s continued service through the applicable vesting date. The performance condition will be satisfied with respect to 100% of an award on the first Carried Interest Payment Date on which the applicable performance hurdles for the Vehicle are satisfied (the “Initial Carried Interest Payment Date”).

In the event that the performance condition is satisfied prior to the full satisfaction of the service condition, (i) with respect to any carried interest award, the service condition will accelerate and be deemed fully satisfied upon the date the performance condition is satisfied, subject to the participant’s continued service through such date; and (ii) with respect to any appreciation interest award, the service condition will continue to be eligible to be satisfied on the applicable service condition satisfaction date(s) following the Initial Carried Interest Payment Date, subject to the participant’s continued service through the applicable vesting date.

​

Payment. Any participant holding a fully vested carried interest award on any Carried Interest Payment Date that occurs with respect to the carry vehicle to which the award relates will be entitled to cash distributions of the carried interest or promote from such carry vehicle. Payments in respect of fully vested appreciation interest awards may be in the form of cash, fully-vested shares of our common stock, fully-vested units in our Operating Partnership or a combination thereof, as determined by the plan administrator. Any shares issued may (or, to the extent required by applicable stock exchange rules, will) be issued under the Incentive Plan or any successor plan. As of September 30, 2025, no amount is anticipated to be paid in the next 12 months.

Individual Payment Limit. In no event may any participant receive aggregate payments or distributions pursuant to awards under the Carried Interest Plan in any calendar year in excess of three times the sum of the participant’s annual base salary rate, target annual bonus and target annual equity award value at the time of payment (or, if a participant is not employed on the payment date, three times the participant’s annual base salary rate, target annual bonus and target annual equity award value as of the day immediately prior to the date on which the participant’s employment terminated).

Award Limit. In no event will more than 50% of the aggregate carried interest or promote distributions made with respect to any Vehicle be paid to participants in respect of awards in the applicable carry vehicle under the Carried Interest Plan. During the three months ended September 30, 2025, we have granted 9% of the 50% permitted to be granted under the Carried Interest Plan.

13. Derivative Instruments

​

Derivatives Designated as Hedging Instruments

​

Net Investment Hedges

​

In September 2022 and November 2024, we entered into cross-currency interest rate swaps, which effectively convert a portion of our U.S. dollar-denominated fixed-rate debt to foreign currency-denominated fixed-rate debt in order to hedge the currency exposure associated with our net investment in foreign subsidiaries. As of September 30, 2025 and December 31, 2024, we had cross-currency interest rate swaps outstanding with notional amounts of $2.3 billion and maturity dates ranging through 2029.

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

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

14. Fair Value

There have been no significant changes in our policy for fair value measurements from what was disclosed in our 2024 Form 10-K.

The carrying amounts for cash and cash equivalents, restricted cash, accounts and other receivables, accounts payable and other accrued liabilities, accrued dividends and distributions, security deposits and prepaid rents approximate fair value because of the short-term nature of these instruments. The carrying value of our Global Revolving Credit Facilities and the Euro Term Loan Facility approximates the estimated fair value, because these liabilities have variable interest rates and our credit ratings have remained stable. Differences between the carrying value and the fair value of our unsecured senior notes and secured and other debt are caused by differences in interest rates or borrowing spreads that were available to us on September 30, 2025 and December 31, 2024 as compared to those in effect when the debt was issued or assumed. As described in Note 13. "Derivative Instruments", outstanding derivative contracts are recorded at fair value.

We calculate the fair value of our secured and other debt and unsecured senior notes based on currently available market rates assuming the loans are outstanding through maturity and considering the collateral and other loan terms. In determining the current market rate for fixed rate debt, a market spread is added to the quoted yields on federal government treasury securities with similar maturity dates to our debt.

15. Commitments and Contingencies

Our properties require periodic investments of capital for tenant-related capital expenditures and for general capital improvements 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 September 30, 2025, we had open commitments, including amounts reimbursable by customers of approximately $63.8 million, related to construction contracts of approximately $2.3 billion.

Legal Proceedings – Although the Company is involved in legal proceedings arising in the ordinary course of business, as of September 30, 2025, 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.

​

As disclosed previously, the Division of Enforcement of the U.S. Securities and Exchange Commission (SEC) is conducting an investigation into the adequacy of our disclosures of cybersecurity risks and our related disclosure controls and procedures. We are cooperating with the SEC and are not aware of any cybersecurity issue or event that caused the Staff to open this matter. Responding to an investigation of this type can be costly and time-consuming. While we are unable to predict the likely outcome of this matter or the potential cost or exposure or duration of the process, based on the information we currently possess, we do not expect the total potential cost to be material to our financial condition. If the SEC believes that violations occurred, it could seek remedies including, but not limited to, civil monetary penalties and injunctive relief, and/or file litigation against the Company.

Insurance – As previously disclosed, in September 2024, an incident at one of our Singapore data centers resulted in damages to the facility. We believe this incident is substantially covered by our insurance policies, including coverage for the repair cost of the building, business interruption loss and potential third-party claims, subject to deductibles. Initial costs, including direct costs related to the incident and an estimated write-off of damage caused to existing fixed assets, totaling approximately $16 million were incurred during 2024. After factoring our expected insurance coverage and related deductible, we reported net expenses of approximately $5.0 million related to this incident for 2024.

​

As of September 30, 2025, we have received total insurance proceeds of $36.8 million to date which includes $15.2 million received for property damage and initial direct costs and $21.6 million received for business interruption losses. We had insurance receivable balances of $7.4 million and $11.6 million, respectively, as of September 30, 2025 and December 31, 2024 for known losses for which insurance reimbursement is probable, which is included in Other assets in the condensed consolidated balance sheets. Insurance proceeds for business interruption losses are recognized in Other income, net in the condensed consolidated income statement as received. No gain contingencies have been recognized as our ability to realize those gains remain uncertain.

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

The following discussion should be read in conjunction with the condensed consolidated financial statements and notes thereto appearing elsewhere in this report and our Annual Report on Form 10-K for the year ended December 31, 2024, and our Quarterly Report on Form 10-Q for the quarters ended March 31, 2025 and June 30, 2025, each as filed with the United States (“U.S.”) Securities and Exchange Commission (“SEC”). This report contains forward-looking statements within the meaning of the federal securities laws. In particular, statements pertaining to our capital resources, expected use of borrowings under our credit facilities, expected use of proceeds from our ATM equity program, litigation matters or legal proceedings, portfolio performance, leverage policy, acquisition and capital expenditure plans, capital recycling program, returns on invested capital, supply and demand for data center space, capitalization rates, rents to be received in future periods and expected rental rates on new or renewed data center space contain forward-looking statements. Likewise, all of our statements regarding anticipated market conditions, and results of operations are forward-looking statements. You can identify forward-looking statements by the use of forward-looking terminology such as “believes,” “expects,” “may,” “will,” “should,” “seeks,” “approximately,” “intends,” “plans,” “pro forma,” “estimates” or “anticipates” or the negative of these words and phrases or similar words or phrases which are predictions of or indicate future events or trends which do not relate solely to historical matters. You can also identify forward-looking statements by discussions of strategy, plans or intentions. Forward-looking statements involve numerous risks and uncertainties, and you should not rely on them as predictions of future events. Forward-looking statements depend on assumptions, data or methods that may be incorrect or imprecise and that we may not be able to realize. We do not guarantee that the transactions and events described will happen as described or that they will happen at all. The following factors, among others, could cause actual results and future events to differ materially from those set forth or contemplated in the forward-looking statements: reduced demand for data centers or decreases in information technology spending; decreased rental rates, increased operating costs or increased vacancy rates; increased competition or available supply of data center space; the suitability of our data centers and data center infrastructure, delays or disruptions in connectivity or availability of power, or failures or breaches of our physical and information security infrastructure or services; breaches of our obligations or restrictions under our contracts with our customers; our inability to successfully develop and lease new properties and development space, and delays or unexpected costs in development of properties; the impact of current global and local economic, credit and market conditions; increased tariffs, global supply chain or procurement disruptions, or increased supply chain costs; the impact from periods of heightened inflation on our costs, such as operating and general and administrative expenses, interest expense and real estate acquisition and construction costs; the impact on our customers’ and our suppliers’ operations during an epidemic, pandemic, or other global events; our dependence upon significant customers, bankruptcy or insolvency of a major customer or a significant number of smaller customers, or defaults on or non-renewal of leases by customers; changes in political conditions, geopolitical turmoil, political instability, civil disturbances, restrictive governmental actions or nationalization in the countries in which we operate; our inability to retain data center space that we lease or sublease from third parties; information security and data privacy breaches; difficulties managing an international business and acquiring or operating properties in foreign jurisdictions and unfamiliar metropolitan areas; our failure to realize the intended benefits from, or disruptions to our plans and operations or unknown or contingent liabilities related to, our recent and future acquisitions; our failure to successfully integrate and operate acquired or developed properties or businesses; difficulties in identifying properties to acquire and completing acquisitions; risks related to joint venture investments, including as a result of our lack of control of such investments; risks associated with using debt to fund our business activities, including re-financing and interest rate risks, our failure to repay debt when due, adverse changes in our credit ratings or our breach of covenants or other terms contained in our loan facilities and agreements; our failure to obtain necessary debt and equity financing, and our dependence on external sources of capital; financial market fluctuations and changes in foreign currency exchange rates; adverse economic or real estate developments in our industry or the industry sectors that we sell to, including risks relating to decreasing real estate valuations and impairment charges and goodwill and other intangible asset impairment charges; our inability to manage our growth effectively; losses in excess of our insurance coverage; our inability to attract and retain talent; environmental liabilities, risks related to natural disasters and our inability to achieve our sustainability goals; the expected operating performance of anticipated near-term acquisitions and descriptions relating to these expectations; our inability to comply with rules and regulations applicable to our Company; Digital Realty

Trust, Inc.’s failure to maintain its status as a REIT for U.S. federal income tax purposes; Digital Realty Trust, L.P.’s failure to qualify as a partnership for U.S. federal income tax purposes; restrictions on our ability to engage in certain business activities; changes in local, state, federal and international laws and regulations, including related to taxation, real estate and zoning laws, and increases in real property tax rates; the impact of any financial, accounting, legal or regulatory issues or litigation that may affect us; and those additional risks and factors discussed in reports filed with the SEC by us from time to time, including those discussed under the heading “Risk Factors” in our most recently filed Annual Report on Form 10-K and in other sections of this report, including under Part II, Item 1A, Risk Factors.

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

The risks included here are not exhaustive, and additional factors could adversely affect our business and financial performance, including factors and risks included in our Annual Report on Form 10-K for the year ended December 31, 2024 and in other sections of this report, including under Part II, Item 1A, Risk Factors. Moreover, we operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time and it is not possible for management to identify all such risk factors, nor can we assess the impact of all such risk factors on the business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Given these risks and uncertainties, you should not place undue reliance on forward-looking statements as a prediction of actual results.

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

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

Business Overview and Strategy

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

Our primary business objectives are to maximize:

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

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

| (iii) | return on invested capital.

​

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

​

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

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

​

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

Changes in political conditions, geopolitical turmoil, political instability, civil disturbances, restrictive governmental actions or nationalization in the countries in which we operate, including escalations in political and trade tensions involving the U.S. and regulatory and legislative changes, could potentially result in adverse effects on our, and our customers’, operations.

On July 4, 2025, a budget reconciliation bill (the “Bill”) was signed into law in the United States. The Bill includes several significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act of 2017 and other changes to the Internal Revenue Code of 1986, as amended (the “Code”), that affect REITs and their investors. We are currently evaluating the full potential impact of the provisions in the Bill, however, we do not expect it to have a material impact on our business.

Summary of 2025 Significant Activities

We completed the following significant activities during the nine months ended September 30, 2025:

| ● | In January 2025, Digital Dutch Finco B.V., an indirect wholly owned finance subsidiary of the Operating Partnership, issued and sold €850 million aggregate principal amount of 3.875% Guaranteed Notes due 2035. Net proceeds from the offering were approximately €838 million (approximately $864 million based on the exchange rate on January 14, 2025) after deducting managers’ discounts and estimated offering expenses.

| ● | In March 2025, we formed a joint venture with Bersama Digital Infrastructure Asia (BDIA) to develop and operate data centers across Indonesia. We acquired a 50% interest in the joint venture, which consists of two land parcels and two buildings in Jakarta, Indonesia for approximately $94.7 million. The 6 acres of land and two buildings can support up to approximately 32 megawatts of IT load.

| ● | In April 2025, we received approximately $77 million of gross proceeds from the contribution of our data centers to the joint venture with Blackstone. As a result of transferring control, we derecognized the data centers and recognized a gain on disposition of approximately $58 million.

​

| ● | During the first half of 2025, the Company launched the Fund, and in May 2025, we received approximately $937 million of gross proceeds from the contribution of operating data centers and development projects to the Fund, recognized a gain on disposition of approximately $873 million, and recognized an investment in the assets of $661 million.

| ● | In June 2025, Digital Dutch Finco B.V., an indirect wholly owned finance subsidiary of the Operating Partnership, issued and sold €850 million aggregate principal amount of 3.875% Guaranteed Notes due 2034 (the “Euro Notes”). Net proceeds from the offering of the Euro Notes were approximately €836.6 million (approximately $975 million based on the exchange rate on June 25, 2025) after deducting managers’ discounts and estimated offering expenses.

| ● | In July 2025, we repaid €650 million in aggregate principal amount of our 0.625% senior notes due 2025.

​

| ● | For the nine months ending September 30, 2025, Digital Realty Trust, Inc. generated net proceeds of approximately $1.0 billion from the issuance of approximately 6.0 million common shares under the 2024 Sales Agreement at an average price of $172.90 per share after payment of approximately $6.3 million of commissions to the agents. As of October 29, 2025, approximately $2.0 billion remains available for future sales under the 2024 Sales Agreement Amendment.

Revenue Base

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

Leasing Activities

Due to the capital-intensive and long-term nature of the operations we support, our lease terms with customers are generally longer than standard commercial leases. As of September 30, 2025, our average remaining lease term was approximately five years.

Our ability to re-lease expiring space at rental rates equal to or in excess of current rental rates will impact our results of operations. The subsequent table summarizes our leasing activity in the nine months ended September 30, 2025 (square feet in thousands):

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

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

(3) | Excludes short-term leases.

(4) | Commencement dates for the leases signed range from 2025 to 2026.

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

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

​

We continue to see strong demand in most of our key metropolitan areas for data center space and, subject to the supply of available data center space in these metropolitan areas, we expect average aggregate rental rates on renewed data center leases for 2025 expirations to be positive as compared with the rates currently being paid for the same space on a GAAP basis and on a cash basis. Our past performance may not be indicative of future results, and we cannot assure you that leases will be renewed or that our data centers will be re-leased at all or at rental rates equal to or above the current average rental rates. Further, re-leased/renewed rental rates in a particular metropolitan area may not be consistent with rental rates across our portfolio as a whole and may fluctuate from one period to another due to a number of factors, including local economic conditions, local supply and demand for data center space, competition from other data center developers or operators, the condition of the property and whether the property, or space within the property, has been developed.

Geographic Concentration

​

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

​ | ​ | ​ | ​
​ |  | Percentage of
​ | ​ | September 30, 2025
Metropolitan Area | ​ | Total annualized rent (1)
Northern Virginia |  | 20.4 | %

Total |  | 100.0 | %

(1) | Annualized rent is monthly contractual rent (defined as cash base rent before abatements) under existing leases as of the end of the period presented, multiplied by 12. Includes consolidated portfolio and unconsolidated entities at the entities’ 100% ownership level. The aggregate amount of abatements for the nine months ended September 30, 2025 was approximately $25.5 million.

Operating Expenses

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

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

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

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

​

Other Income / (Expenses)

Equity in earnings of unconsolidated entities, gain on disposition of properties, interest expense, and income tax expense make up the majority of Other income/(expenses). Equity in earnings of unconsolidated entities represents our share of the income/(loss) of entities in which we invest, but do not consolidate under U.S. GAAP. Refer to additional discussion of Digital Core REIT and Ascenty in the Notes to the Condensed Consolidated Financial Statements.

Results of Operations

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

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

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

A roll forward showing changes in the stabilized and non-stabilized portfolios for the nine months ended September 30, 2025 as compared to December 31, 2024 is shown below (in thousands):

​

Total operating revenues increased by approximately $146.0 million and $358.9 million in the three and nine months ended September 30, 2025, respectively, compared to the same periods in 2024.

​

Stabilized rental and other services revenue increased by approximately $73.5 million and $160.7 million in the three and nine months ended September 30, 2025, respectively, compared to the same periods in 2024 primarily due to increases in new leasing and renewals across all regions along with the strengthening of foreign exchange rates, primarily the Euro, British pound sterling and Singapore dollar.

​

Non-stabilized rental and other services revenue increased by approximately $48.8 million and $149.7 million in the three and nine months ended September 30, 2025, respectively, compared to the same periods in 2024 primarily due to:

​

| (i) | increases of $114.4 million and $290.8 million, respectively, due to the completion of our global development pipeline and related lease up operating activities (with the biggest contributions in Northern Virginia, Portland and Johannesburg); and

| (ii) | offset by decreases of $65.6 million and $141.2 million, respectively, related to properties sold or contributed after September 30, 2024.

​

​

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

Total Utilities

Total stabilized utilities expenses increased by approximately $5.1 million and $7.8 million in the three and nine months ended September 30, 2025, respectively, compared to the same periods in 2024. The increase was primarily due to higher power pricing at certain properties in the stabilized portfolio, mainly in EMEA and APAC, offset by rebates received mainly in EMEA.

Total non-stabilized utilities expenses increased by approximately $14.4 million and $24.7 million in the three and nine months ended September 30, 2025, respectively, compared to the same periods in 2024 primarily due to:

| (i) | an increase of approximately $34.6 million and $75.4 million, respectively, due to higher utility consumption in a growing portfolio of recently completed development sites (with the biggest contributions in Northern Virginia, Portland and Johannesburg); offset by

| (ii) | a decrease in power agreement charges by $3.3 million and $11.7 million, respectively; and

| (iii) | a decrease of $16.9 million and $39.1 million, respectively, related to properties sold or contributed after September 30, 2024.

​

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

Total Rental Property Operating and Maintenance (Excluding Utilities)

Total stabilized rental property operating and maintenance expenses (excluding utilities) increased by approximately $24.3 million and $46.5 million in the three and nine months ended September 30, 2025, respectively, compared to the same periods in 2024 primarily due to increases in building operations expense, common area maintenance expense and data center labor.

Total non-stabilized rental property operating and maintenance expenses (excluding utilities) increased by approximately $4.2 million and $26.3 million in the three and nine months ended September 30, 2025, respectively, compared to the same periods in 2024 primarily due to increases in data center labor expense throughout the portfolio.

Total Property Taxes and Insurance

Total stabilized property taxes and insurance increased by approximately $6.2 million and $4.6 million in the three and nine months ended September 30, 2025, respectively, compared to the same periods in 2024, primarily due to timing of property tax assessments throughout our North American portfolio.

Total non-stabilized property taxes and insurance decreased by approximately $0.4 million and increased by approximately $10.9 million in the three and nine months ended September 30, 2025, respectively, compared to the same periods in 2024, primarily related to property tax reassessments for certain properties located in Chicago, Northern Virginia and Portland in the non-stabilized portfolio.

​

Other Operating Expenses

​

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

​

Transactions and Integration

​

Transactions and integration expenses increased $62.4 million and $66.9 million in the three and nine months ended September 30, 2025, respectively, compared to the same periods in 2024 driven primarily by placement fees associated with securing capital commitments to the Fund and lease termination expenses in connection with acquisitions.

Equity in Earnings (Loss) of Unconsolidated Entities

​

The change in Equity in earnings (loss) of unconsolidated entities was approximately $9.5 million and $47.3 million in the three and nine months ended September 30, 2025, respectively, compared to the same periods in 2024. The foreign exchange remeasurement of debt associated with our unconsolidated Ascenty entity creates volatility in our equity in earnings and drove this fluctuation.

​

Gain on Disposition of Properties, Net

​

Gain on disposition of properties increased $20.3 million and $501.8 million in the three and nine months ended September 30, 2025, respectively, compared to the same periods in 2024.

​

During the quarter, we sold three non-core data centers in the Atlanta, Miami and Boston metro areas for gross proceeds of approximately $90 million and recognized a gain on disposition of approximately $20 million.

​

In May 2025, we received approximately $937 million of gross proceeds from the contribution of operating data centers and development projects to the Fund, recognized a gain on disposition of approximately $873 million, and recognized an investment in the assets of $661 million.

​

In April 2025, we contributed an additional three development projects at the Digital Dulles campus to the joint venture with Blackstone. We received approximately $77 million of gross proceeds from the contribution and as a result of transferring control, we derecognized the data centers and recognized a gain on disposition of approximately $58 million.

​

In January 2024, we closed on the sale of our interest in four data centers to Brookfield Infrastructure Partners L.P., or Brookfield, for approximately $271 million. As a result of the sale, we recognized a total gain on disposition of approximately $194.2 million.

In March 2024, we recognized a total gain of $74.4 million from the sale of an easement to a local power provider in Northern Virginia.

Interest Expense

Interest expense decreased $10.2 million and $26.7 million in the three and nine months ended September 30, 2025, respectively, compared to the same periods in 2024 driven primarily by lower average balances on our Global Revolving Credit Facilities and term loan facilities offset by issuances of unsecured senior notes (€850 million of 3.875% Guaranteed Notes due 2033 (issued in September 2024), $1.15 billion of 1.875% Exchangeable Senior Notes due 2029 (issued in November 2024), €850 million of 3.875% Guaranteed Notes due 2035 (issued in January 2025) and €850 million of 3.875% Guaranteed Notes due 2034 (issued in June 2025).

​

Loss on Debt Extinguishment and Modifications

We incurred no losses on debt extinguishment and debt modifications in the three and nine months ended September 30, 2025.

​

In January 2024, we paid down $240 million on the U.S. term loan facility, leaving $500 million outstanding. The paydown resulted in an early extinguishment charge of approximately $1.1 million.

In September 2024, we paid down €375 million on the Euro Term Loan Facilities, leaving €375 million outstanding. The paydown resulted in an early extinguishment charge of approximately $1.6 million. We also refinanced our Global Revolving Credit Facilities and wrote off deferred loan costs of approximately $1.2 million.

​

Income Tax Expense

Income tax expense decreased $0.7 million and $8.1 million in the three and nine months ended September 30, 2025, respectively, compared to the same periods in 2024 due to jurisdictional rate mix in foreign jurisdictions and internal restructuring within the global group. We carried out an analysis for the purposes of the Model GloBE Rules for Pillar Two and no material top-up tax is expected.

As of September 30, 2025, we are under examination for various years in Belgium, Germany, Greece, Kenya, Mauritius, Singapore, Switzerland, United Kingdom and the United States.

Liquidity and Capital Resources

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

Analysis of Liquidity and Capital Resources — Parent

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

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

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

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

Our Parent and our Operating Partnership are parties to an ATM Equity OfferingSM Sales Agreement dated December 23, 2024 (the “2024 Sales Agreement”). Pursuant to the 2024 Sales Agreement, Digital Realty Trust, Inc. can issue and sell common stock having an aggregate offering price of up to $3.0 billion through various named agents from time to time.

​

58

Table of Contents

​

The sales of common stock made under the 2024 Sales Agreement Amendment will be made in “at the market” offerings as defined in Rule 415 of the Securities Act. Our Parent has used and intends to use the net proceeds from the program to temporarily repay borrowings under our Operating Partnership’s Global Revolving Credit Facilities, to acquire additional properties or businesses, to fund development opportunities and for working capital and other general corporate purposes, including potentially for the repayment of other debt or the repurchase, redemption or retirement of outstanding debt securities. Since June 30, 2025, Digital Realty Trust, Inc. generated net proceeds of approximately $501 million from the issuance of approximately 2.9 million common shares under the 2024 Sales Agreement at an average price of $172.46 per share after payment of approximately $2.9 million of commissions to the agents. As of October 29, 2025, approximately $2.0 billion remains available for future sales under the 2024 Sales Agreement Amendment.

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

Future Uses of Cash — Parent

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

​

Dividends and Distributions — Parent

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

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

59

Table of Contents

​

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

For additional information regarding dividends declared and paid by our Parent on its common and preferred stock for the nine months ended September 30, 2025, see Note 10. “Equity and Capital” to our condensed consolidated financial statements contained herein.

Analysis of Liquidity and Capital Resources — Operating Partnership

As of September 30, 2025, we had $3,299.7 million of cash and cash equivalents, excluding $6.3 million of restricted cash. Restricted cash primarily consists of contractual capital expenditures plus other deposits. As circumstances warrant, our Operating Partnership may dispose of assets or enter into joint venture arrangements with institutional investors or strategic partners, on an opportunistic basis dependent upon market conditions. Our Operating Partnership may use the proceeds from such dispositions to acquire additional properties, to fund development opportunities and for general working capital purposes, including the repayment of indebtedness. Our liquidity requirements primarily consist of:

​

| ● | operating expenses;

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

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

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

| ● | debt service; and

| ● | potentially, acquisitions.

​

On September 24, 2024, we refinanced our Global Revolving Credit Facility and Yen Revolving Credit Facility. The Global Revolving Credit Facilities provide for borrowings up to $4.5 billion (including approximately $0.3 billion available to be drawn on the Yen Revolving Credit Facility) based on currency commitments and foreign exchange rates as of September 30, 2025. The Global Revolving Credit Facility provides for borrowings in a variety of currencies and can be increased by an additional $1.8 billion, subject to receipt of lender commitments and other conditions precedent. Both facilities mature on January 24, 2029, with two six-month extension options available.

These facilities also feature a sustainability-linked pricing component, with pricing subject to adjustment based on annual performance targets, further demonstrating our continued leadership and commitment to sustainable business practices.

The Global Revolving Credit Facility provides for borrowings in a variety of currencies and includes the ability to add additional currencies in the future. We have used and intend to use available borrowings under the Global Revolving Credit Facilities to acquire additional properties, fund development opportunities and for general working capital and other corporate purposes, including potentially for the repurchase, redemption or retirement of outstanding debt or equity securities. For additional information regarding our Global Revolving Credit Facility, see Note 8. “Debt of the Operating Partnership” in the Notes to our Condensed Consolidated Financial Statements.

Future Uses of Cash

Our properties require periodic investments of capital for customer-related capital expenditures and for general capital improvements. Depending upon customer demand, we expect to incur significant improvement costs to build out and develop additional capacity. At September 30, 2025, we had open commitments, related to construction contracts of approximately $2.3 billion, including amounts reimbursable of approximately $63.8 million.

For the remainder of 2025, we currently expect to incur approximately $1.2 billion to $1.7 billion of capital expenditures, which includes our share of joint venture contributions and is net of partner contributions for our development programs. This amount could go up or down, potentially materially, based on numerous factors, including changes in demand, leasing results and availability of debt or equity capital.

Development Projects

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

(2) | Represents estimated cost to complete scope of work pursuant to approved development budget.

(3) | Represents costs incurred through December 31, 2024.

(4) | Includes land and space held or actively under construction in preparation for future data center fit-out.

(5) | Represents long-lead equipment and materials required for timely deployment and delivery of data center fit-out.

(6) | Represents improvements in progress, which benefit space recently converted to our operating portfolio and is composed primarily of shared infrastructure projects and first-generation tenant improvements.

​

Future development reflects cumulative cost spent pending future development and includes ongoing improvements to building infrastructure in preparation for future data center fit-out. We expect to deliver the space within 12 months; however, lease commencement dates may significantly impact final delivery schedules.

Capital Expenditures (Cash Basis)

The table below summarizes our capital expenditure activity for the nine months ended September 30, 2025 and 2024 (in thousands):

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Nine Months Ended September 30,
​ |  | 2025 |  | 2024
Development projects | ​ | $ | 1,784,380 | ​ | $ | 1,732,337
Enhancement and improvements | ​ |  | 23,936 | ​ |  | 21,859
Recurring capital expenditures | ​ |  | 175,386 | ​ |  | 175,467
Total capital expenditures (excluding indirect costs) | ​ | $ | 1,983,702 | ​ | $ | 1,929,663

​

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

Indirect costs, including interest, capitalized in the nine months ended September 30, 2025 and 2024 were $195.3 million and $166.7 million, respectively. Capitalized interest comprised approximately $92.4 million and $84.4 million of the total indirect costs capitalized for the nine months ended September 30, 2025 and 2024, respectively. Capitalized interest in the nine months ended September 30, 2025 increased, compared to the same period in 2024, due to an increase in qualifying activities and higher interest rates.

Excluding capitalized interest, indirect costs in the nine months ended September 30, 2025 increased compared to the same period in 2024 due primarily to capitalized amounts relating to compensation expense of employees directly engaged in construction activities. See “Future Uses of Cash” for a discussion of the amount of capital expenditures we expect to incur during the year ending December 31, 2025.

Consistent with our growth strategy, we actively pursue potential acquisition opportunities, with due diligence and negotiations often at different stages at different times. The dollar value of acquisitions for the year ending December 31, 2025 will depend upon numerous factors, including customer demand, leasing results, availability of debt or equity capital and acquisition opportunities. Further, the growing acceptance by private institutional investors of the data center asset class has generally pushed capitalization rates lower, as such private investors may often have lower return expectations than us. As a result, we anticipate near-term single asset acquisitions activity to comprise a smaller percentage of our growth while this market dynamic persists.

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

Sources of Cash

We expect to meet our short-term and long-term liquidity requirements, including payment of scheduled debt maturities and funding of acquisitions and non-recurring capital improvements, with net cash from operations, future long-term secured and unsecured indebtedness and the issuance of equity and debt securities and the proceeds of equity issuances by our Parent. We also may fund future short-term and long-term liquidity requirements, including acquisitions and non-recurring capital improvements, using our Global Revolving Credit Facilities pending permanent financing. As of October 29, 2025, we had approximately $3.2 billion of borrowings available under our Global Revolving Credit Facilities.

On March 1, 2024, we formed a joint venture with Mitsubishi Corporation, or Mitsubishi, to support the development of two data centers in the Dallas metro area. The facilities were 100% pre-leased prior to construction. We contributed the two data center buildings at a contribution value of approximately $261 million. In 2024, we received approximately $153 million of gross proceeds from the contribution of our data centers to the joint venture and retained a 35% interest in the joint venture. Mitsubishi contributed such cash in exchange for a 65% interest in the joint venture. Each partner funded its pro rata share of the remaining $140 million estimated development cost for the first phase of the project, of which one project was completed in June 2024 and another was completed in October 2024. On January 31, 2025, Mitsubishi made an additional cash capital contribution in the amount of $62 million, resulting in an additional 15% ownership in the joint venture. The transaction resulted in a gain of approximately $5.1 million. Currently, Mitsubishi has an 80% interest in the joint venture, and we have retained a 20% interest.

During the first half of 2025, the Company launched its first U.S. Hyperscale Data Center Fund (the “Fund”), successfully raising more than $3 billion of equity commitments to date. Fund commitments represent a 40% to 80% ownership interest in each individual asset, while the Company will maintain the remaining 20% to 60% stake in the assets and less than a 2% direct interest in the Fund. The initial portfolio includes five operating data centers plus three land sites with access to power for data center development. In May 2025, we received approximately $937 million of gross proceeds from the contribution of operating data centers and development projects to the Fund, recognized a gain on disposition of approximately $873 million, and recognized an investment in the assets of $661 million. The Company will serve as general partner, maintaining operational and management responsibilities for the assets, however, certain governance rights are granted to the limited partners. As such, we concluded we do not own a controlling interest and account for our interest in the assets under the equity method of accounting. These real estate assets were previously classified as held for sale and contribution. Additionally, as of June 30, 2025, one additional development project was classified within Assets held for sale and contribution on our condensed consolidated balance sheet as it is probable it will be contributed to the fund within one year. The disposition of a portion of our interest in the remaining development project met the criteria under ASC 360 for the assets to qualify as held for sale and contribution. However, the operations are not classified as discontinued operations as a result of our continuing interest in the assets. This development project was not representative of a significant component of our portfolio, nor will the contribution represent a significant shift in our strategy.

​

On April 3, 2025, we received approximately $77 million of gross proceeds from the contribution of our data centers to the joint venture with Blackstone. As a result of transferring control, we derecognized the data centers and recognized a gain on disposition of approximately $58 million.

​

During the quarter, we sold three non-core data centers in the Atlanta, Miami and Boston metro areas for gross proceeds of approximately $90 million and recognized a gain on disposition of approximately $20 million.

​

Distributions

All distributions on our units are at the discretion of our Parent’s Board of Directors. For additional information regarding distributions paid on our common and preferred units for the three and nine months ended September 30, 2025, see Note 10. “Equity and Capital” to our condensed consolidated financial statements contained herein.

Fixed rate (including hedged variable rate debt) | ​ |  | 2.79 | %
Variable rate | ​ |  | 2.33 | %
Effective interest rate | ​ |  | 2.75 | %

​

Our ratio of debt to total enterprise value was approximately 23.0% (based on the closing price of Digital Realty Trust, Inc.’s common stock on September 30, 2025 of $172.88). For this purpose, our total enterprise value is defined as the sum of the market value of Digital Realty Trust, Inc.’s outstanding common stock (which may decrease, thereby increasing our debt to total enterprise value ratio), plus the liquidation value of Digital Realty Trust, Inc.’s preferred stock, plus the aggregate value of Digital Realty Trust, L.P. units not held by Digital Realty Trust, Inc. (with the per unit value equal to the market value of one share of Digital Realty Trust, Inc.’s common stock and excluding long-term incentive units, Class C units and Class D units), plus the book value of our total consolidated indebtedness.

The variable rate debt shown above bears interest based on various one-month SOFR, EURIBOR, HIBOR, TIBOR, JIBAR, SARON and Base CD Rate rates, depending on the respective agreement governing the debt, including our Global Revolving Credit Facilities and unsecured term loans. As of September 30, 2025, our debt had a weighted average term to initial maturity of approximately 4.4 years (or approximately 4.5 years assuming exercise of extension options).

As of September 30, 2025, our pro-rata share of secured debt of unconsolidated entities was approximately $2.1 billion.

Table of Contents

​

​

Cash provided by operating activities in 2025 increased $201.2 million over 2024. The increase was driven by:

| (i) | an increase in revenues due to the completion of our global development pipeline and related lease up operating activities;

| (ii) | an increase in interest income as a result of carrying higher cash balances;

| (iii) | a decrease in interest expense due to lower average balances on our Global Revolving Credit Facilities and unsecured term loans;

| (iv) | offset by the net impact of properties sold and contributed in 2024 and 2025.

​

The changes in the activities that comprise the increase in net cash used in investing activities for the nine months ended September 30, 2025 as compared to the nine months ended September 30, 2024 consisted of the following amounts (in thousands).

​

​ | ​ | ​
​ | Change
​ | 2025 vs 2024
Decrease in net cash used in business combinations / asset acquisitions | $ | 29,284
Increase in cash used for improvements to investments in real estate | ​ | (82,688)
Increase in cash contributed to investments in unconsolidated entities, net | ​ | (38,615)
Decrease in net cash provided by proceeds from sale of real estate | ​ | (86,639)
Other changes |  | 101,427
Increase in net cash used in investing activities | $ | (77,231)

​

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

| (i) | a decrease in spend due to the acquisition of land parcels for $285 million in 2025 compared to the acquisition of land parcels in Paris and two data centers located in the Slough Trading Estate in 2024;

| (ii) | an increase in spend on development projects of approximately $83 million;

| (iii) | an increase in cash contributed to various investments in unconsolidated entities;

| (iv) | a decrease in cash provided by the sale or contributions of data centers due to:

| ● | approximately $1.2 billion provided for the nine months ended September 30, 2024:

i. |  | cash provided by the contribution of data centers to our joint ventures with Blackstone and Mitsubishi, for gross proceeds of approximately $231 million and $153 million, respectively;

ii. |  | the sale of four data centers to Brookfield for gross proceeds of approximately $271 million, the sale of a land parcel in Sydney for gross proceeds of approximately $68 million and the sale of an easement to a local power provider in Northern Virginia for gross proceeds of approximately $92 million;

iii. |  | the sale to GI Partners of a 75% interest in a third facility in Chicago. We received approximately $386 million of net proceeds and retained a 25% interest in the joint venture;

| ● | offset by approximately $1.2 billion provided for the nine months ended September 30, 2025:

i. |  | a $62 million cash contribution made by Mitsubishi in January 2025, which increased their ownership in the joint venture from 65% to 80%;

ii. |  | cash provided by the contribution of development projects at the Digital Dulles campus to the joint venture with Blackstone in April 2025, for gross proceeds of approximately $77 million;

iii. |  | cash provided by the contribution of data centers and development projects to the Fund in May 2025, for gross proceeds of approximately $937 million; and

iv. |  | cash provided by the sale of non-core data centers in the third quarter of 2025, for gross proceeds of approximately $90 million.

Noncontrolling Interests in Operating Partnership

Noncontrolling interests relate to the common units in Digital Realty Trust, L.P. that are not owned by Digital Realty Trust, Inc., which, as of September 30, 2025, amounted to 1.8% of Digital Realty Trust, L.P. common units. Historically, Digital Realty Trust, L.P. has issued common units to third party sellers in connection with our acquisition of real estate interests from such third parties.

Limited partners have the right to require Digital Realty Trust, L.P. to redeem part or all of their common units for cash based on the fair market value of an equivalent number of shares of Digital Realty Trust, Inc. common stock at the time of redemption. Alternatively, Digital Realty Trust, Inc. may elect to acquire those common units in exchange for shares of its common stock on a one-for-one basis, subject to adjustment in the event of stock splits, stock dividends, issuance of stock rights, specified extraordinary distributions and similar events. As of September 30, 2025, common units and incentive units of Digital Realty Trust, L.P. are classified within equity, except for certain common units of approximately 0.2 million issued to certain former DuPont Fabros Technology, L.P. unitholders in the Company’s acquisition of DuPont Fabros Technology, Inc., which are subject to certain restrictions and, accordingly, are not presented as permanent equity in the condensed consolidated balance sheet.

Inflation

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

Funds from Operations

We calculate funds from operations, or FFO, in accordance with the standards established by the National Association of Real Estate Investment Trusts (Nareit) in the Nareit Funds From Operations White Paper - 2018 Restatement. FFO is a non-GAAP financial measure and represents net income (loss) (computed in accordance with GAAP), excluding gain (loss) from the disposition of real estate assets, provision for impairment, real estate related depreciation and amortization (excluding amortization of deferred financing costs), our share of unconsolidated JV real estate related depreciation & amortization, net income attributable to noncontrolling interests in operating partnership and, reconciling items related to noncontrolling interests. Management uses FFO as a supplemental performance measure because, in excluding real estate related depreciation and amortization and gains and losses from property dispositions and after adjustments for unconsolidated partnerships and joint ventures, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. We also believe that, as a widely recognized measure of the performance of REITs, FFO will be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our data centers that result from use or market conditions, nor the level of capital expenditures and capitalized leasing commissions necessary to maintain the operating performance of our data centers, all of which have real economic effect and could materially impact our financial condition and results from operations, the utility of FFO as a measure of our performance is limited. Other REITs may not calculate FFO in accordance with the Nareit definition and, accordingly, our FFO may not be comparable to other REITs’ FFO. FFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.

(2) | As part of the acquisition of Teraco in 2022, certain of Teraco's minority indirect shareholders have the right to put their shares in an upstream parent company of Teraco to the Company in exchange for cash or the equivalent value of shares of the Company common stock, or a combination thereof. U.S. GAAP requires the Company to assume the put right is settled in shares for purposes of calculating diluted EPS. This same approach was utilized to calculate FFO per share. When calculating diluted FFO, Teraco related minority interest is added back to the FFO numerator as the denominator assumes all shares have been put back to the Company. The Teraco noncontrolling share of FFO was $17,018 and $9,828 for the three months ended September 30, 2025 and 2024, respectively, and $45,326 and $32,049 for the nine months ended September 30, 2025 and 2024, respectively.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

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

Analysis of Debt between Fixed and Variable Rate

We use interest rate swap agreements and fixed rate debt to reduce our exposure to interest rate movements. As of September 30, 2025, our consolidated debt was as follows (in millions):

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | Outstanding |  | Estimated Fair
​ | ​ | Balance |  | Value
Fixed rate debt | ​ | $ | 14,026 | ​ | $ | 13,458
Variable rate debt subject to interest rate swaps | ​ |  | 2,651 | ​ |  | 2,651
Total fixed rate debt (including interest rate swaps) | ​ |  | 16,677 | ​ |  | 16,109
Variable rate debt | ​ |  | 1,693 | ​ |  | 1,693
Total outstanding debt | ​ | $ | 18,370 | ​ | $ | 17,802

​

Sensitivity to Changes in Interest Rates

The following table shows the effect if assumed changes in interest rates occurred, based on fair values and interest expense as of September 30, 2025:

​

​ | ​ | ​ | ​
​ |  | Change
Assumed event | ​ | ($ millions)
Increase in fair value of interest rate swaps following an assumed 10% increase in interest rates | ​ | $ | 0
Decrease in fair value of interest rate swaps following an assumed 10% decrease in interest rates | ​ |  | (0)
Increase in annual interest expense on our debt that is variable rate and not subject to swapped interest following a 10% increase in interest rates | ​ |  | 5
Decrease in annual interest expense on our debt that is variable rate and not subject to swapped interest following a 10% decrease in interest rates | ​ |  | (5)
Increase in fair value of fixed rate debt following a 10% decrease in interest rates | ​ |  | (173)
Decrease in fair value of fixed rate debt following a 10% increase in interest rates | ​ |  | (163)

​

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

Foreign Currency Exchange Risk

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

ITEM 4. CONTROLS AND PROCEDURES

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

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

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

Changes in Internal Control over Financial Reporting

​

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

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

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

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

Changes in Internal Control over Financial Reporting

​

There have been no changes in the Operating Partnership’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.
