Solid performance yields 24.7% year-over-year growth in FFO per diluted share and unit

San Francisco, Calif. (October 27, 2011) – Digital Realty Trust, Inc. (NYSE: DLR), a leading global provider of data center solutions, today announced financial results for the third quarter of 2011.

Highlights:

• Reported FFO of $1.01 per diluted share and unit for the quarter ended September 30, 2011, up 24.7% from $0.81 per diluted share and unit in the third quarter of 2010. Excluding certain items that do not represent ongoing expenses or revenue streams in each quarter, third quarter 2011 FFO was $1.02 per diluted share and unit, up 13.3% from third quarter 2010 FFO of $0.90 per diluted share and unit;

• Reported net income for the quarter ended September 30, 2011 of $37.7 million and net income available to common stockholders of $31.9 million, or $0.31 per diluted share, up from $0.11 per diluted share in the third quarter of 2010;

• Completed the acquisition of a 69,000 square foot fully leased data center facility in Sacramento, California for a purchase price of $30.0 million;

• Entered the Australian data center market with the acquisition of an 8.6 acre development site in Sydney, Australia for AU $10.1 million;

• Completed second transaction in Australia with the acquisition of a 7.5 acre development site in Melbourne, Australia for AU $4.1 million;

• Acquired a 130,000 square foot building for redevelopment in London, U.K. for a purchase price of £12.9 million;

• Acquired a 5.1 acre site in Hillsboro, Oregon for a purchase price of $1.6 million for the development of a Build-to-Suit project;

• Signed leases during the quarter ended September 30, 2011 totaling approximately 186,000 square feet of space at an average annual GAAP rental rate of approximately $111.00 per square foot, including non-technical space;

• Commenced leases totaling approximately 249,000 square feet during the third quarter of 2011 at an average annual GAAP rental rate of approximately $98.00 per square foot, including non-technical space;

• Issued approximately 4.1 million shares during the third quarter under the Company’s At-the-Market (“ATM”) equity distribution program for net proceeds totaling $237.6 million at an average price of $58.38 per share;

• Launched a $1.5 billion multi-currency revolving credit facility expected to close in early November 2011 to replace the Company’s Corporate Revolving Credit Facility and Asia Pacific Revolving Credit Facility;

• Closed a $100 million USD equivalent Asia Pacific Revolving Credit Facility with a $100 million USD equivalent accordion with the ability to borrow in Singapore and Australian Dollars;

• Completed a 7.000% Series E Cumulative Redeemable Preferred Stock Offering selling 11.5 million shares, including the underwriter’s over-allotment option, raising net proceeds of $277.4 million; and

• Narrowed 2011 guidance range to between $4.02 and $4.05 per diluted share and unit, increasing the midpoint of the range by $0.02.

Funds from operations (“FFO”) on a diluted basis was $121.3 million in the third quarter of 2011, or $1.01 per diluted share and unit, compared to $1.02 per diluted share and unit in the second quarter of 2011, and up 24.7% from $0.81 per diluted share and unit in the third quarter of 2010.

“Core FFO is FFO adjusted for certain items that we believe do not represent ongoing expenses or revenue streams of our core business. Third quarter 2011 core FFO was $1.02 per diluted share and unit, unchanged from the second quarter of 2011, and up 13.3% from third quarter 2010 core FFO of approximately $0.90 per diluted share and unit,” said A. William Stein, Chief Financial Officer and Chief Investment Officer of Digital Realty. “The decrease in reported FFO on a diluted share and unit basis in the third quarter, compared to the second quarter, was primarily due to transaction expenses and additional shares issued through our ATM equity distribution program. These two items were partially offset by foreign exchange transaction gains related to exchange rate movement on Euro and British Pound Sterling draws on our Corporate Revolving Credit Facility.”

FFO is a supplemental non-GAAP performance measure used by the real estate industry to measure the operating performance of real estate investment trusts. FFO and core FFO should not be considered as substitutes for net income determined in accordance with U.S. GAAP as measures of financial performance. A reconciliation from U.S. GAAP net income available to common stockholders to FFO, a definition of FFO, a reconciliation from FFO to core FFO, and a definition of core FFO is included as an attachment to this press release.

Net income for the third quarter of 2011 was $37.7 million, down 1.3% from $38.2 million in the second quarter of 2011 and up 59.7% from $23.6 million in the third quarter of 2010. Net income available to common stockholders in the third quarter of 2011 was $31.9 million, or $0.31 per diluted share, compared to $32.0 million, or $0.33 per diluted share, in the second quarter of 2011, and up from $9.6 million, or $0.11 per diluted share, in the third quarter of 2010.

The Company reported total operating revenues of $273.5 million in the third quarter of 2011, up 2.1% from $267.9 million in the second quarter of 2011 and up 15.2% from $237.5 million in the third quarter of 2010.

“Despite the volatile capital market conditions, Digital Realty delivered another strong performance in the third quarter. Consistent with our approach to managing our business during the 2008 downturn, we have remained focused on providing customers with a variety of data center solutions to support their IT infrastructure needs. When combined with our strong balance sheet, financial resources, and attractively priced capital, we are able to support our customers’ growth over the long term, while generating attractive risk-adjusted returns for our shareholders,” said Michael F. Foust, Chief Executive Officer of Digital Realty. “We believe our global operating platform, suite of flexible data center solutions and investment and development expertise will continue to make Digital Realty the best choice for enterprise customers looking for a reliable and financially secure data center partner.”

Balance Sheet Update

Total assets grew to approximately $5.8 billion at September 30, 2011, up from approximately $5.7 billion at June 30, 2011. Total debt at September 30, 2011 was approximately $2.8 billion, down from $3.1 billion at June 30, 2011. Stockholders’ equity was approximately $2.5 billion at September 30, 2011, up from approximately $2.1 billion at June 30, 2011.

In August 2011, the Company exchanged the remaining $48.3 million aggregate principal amount of its 4.125% Exchangeable Senior Debentures due 2026 for a combination of shares of its common stock and cash.

For the three months ended September 30, 2011, under its ATM equity distribution program, the Company issued approximately 4.1 million shares of common stock for net proceeds totaling approximately $237.6 million at an average price of $58.38 per share. The proceeds have been used to repay borrowings under the Company’s revolving credit facility, to acquire additional properties, to fund development and redevelopment opportunities and for general corporate purposes.

On September 15, 2011, the Company completed an offering of its 7.000% Series E Cumulative Redeemable Preferred Stock selling 11.5 million shares, including shares sold pursuant to the underwriters’ exercise in full of their over-allotment option, and raised net proceeds of $277.4 million.

During the third quarter, holders of the Company’s Series C Convertible Preferred Stock converted approximately 145,000 shares of the Series C Convertible Preferred Stock with a liquidation preference value of $3.6 million into 77,000 newly issued shares of common stock at the request of holders pursuant to the terms of such preferred stock.

“We continued our strategy of accessing attractively priced capital with the issuance of the 7.000% Series E Cumulative Redeemable Preferred Stock and through sales under our ATM equity distribution program,” said Mr. Stein. “At the same time, we expect to close the syndication of a $1.5 billion multi-currency, unsecured revolving credit facility in early November. These efforts will further strengthen our balance sheet, increase our liquidity and provide sufficient capital to fund the growth of the Company.”

The Company plans to provide its initial 2012 guidance in January 2012.

2011 Revised Outlook

FFO per diluted share and unit for the year ending December 31, 2011 is projected to range between $4.02 and $4.05. This guidance represents expected FFO growth of 18.6% to 19.5% over 2010 FFO of $3.39 per diluted share and unit. After adjusting for certain items that do not represent core revenue and expense streams for the full years 2011 and 2010, core FFO per diluted share and unit for the year ending December 31, 2011 is projected to be between $4.07 and $4.09, which represents expected core FFO growth of 16.6% to 17.2% over the 2010 core FFO of $3.49 per diluted share and unit adjusted for $0.10 of non-core revenue and expense items. A reconciliation of the range of 2011 projected net income to projected FFO as reported and core FFO is as follows:

	Low				High
Net income available to common stockholders per diluted share	$	1.34	—		$	1.37
Add:
Real estate depreciation and amortization as adjusted for noncontrolling interests				$3.00
Less:
Dilutive impact of convertible stock and exchangeable debentures				($0.32)
Projected FFO per diluted share	$	4.02	—		$	4.05
As adjusted for items that do not represent core expense and revenue streams:
Reported Q1 items				$0.01
Reported Q2 items				$0.01
Reported Q3 items				$0.01
Projected Q4 transaction expenses and FX impact				$0.02 - $0.01
Projected core FFO per diluted share	$	4.07	—		$	4.09

Note Regarding Funds From Operations

Digital Realty Trust calculates Funds from Operations, or FFO, in accordance with the standards established by the National Association of Real Estate Investment Trusts, or NAREIT. FFO represents net income (loss) available to common stockholders and unitholders (computed in accordance with U.S. GAAP), excluding gains (or losses) from sales of property, real estate related depreciation and amortization (excluding amortization of deferred financing costs) and after adjustments for unconsolidated partnerships and joint ventures. Management uses FFO as a supplemental performance measure because, in excluding real estate related depreciation and amortization and gains and losses from property dispositions, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. Digital Realty Trust also believes that, as a widely recognized measure of the performance of REITs, FFO will be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our properties that result from use or market conditions, nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effect and could materially impact our financial condition and results from operations, the utility of FFO as a measure of our performance is limited. Other REITs may not calculate FFO in accordance with the NAREIT definition and, accordingly, our FFO may not be comparable to such other REITs’ FFO. Accordingly, FFO should be considered only as a supplement to net income as a measure of our performance.

Core Funds from Operations

We present core funds from operations, or CFFO, as a supplemental operating measure because, in excluding certain items that do not reflect ongoing revenue or expense streams, it provides a performance measure that, when compared year over year, captures trends in our core business operating performance. We calculate CFFO by adding to or subtracting from FFO (i) termination fees and other non-core revenues, (ii) significant transaction expenses, (iii) loss from early extinguishment of debt, (iv) costs on redemption of preferred stock, (v) significant property tax adjustments, net and (vi) other non-core expense adjustments. Because certain of these adjustments have a real economic impact on our financial condition and results from operations, the utility of CFFO as a measure of our performance is limited. Other equity REITs may not calculate CFFO in a consistent manner. Accordingly, our CFFO may not be comparable to other REITs’ CFFO. CFFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.

Statement Regarding Forward-Looking Statements

This supplemental package contains forward-looking statements within the meaning of the federal securities laws, including information related to trends, leasing expectations, weighted average lease terms, the exercise of lease extensions, lease expirations, debt maturities, annualized rent at expiration of leases, the effect new leases and increases in rental rates will have on our rental revenue, our credit ratings, construction and redevelopment activity, projected construction costs and other forward-looking financial data. Such statements are based on management’s beliefs and assumptions made based on information currently available to management. Such statements are subject to risks, uncertainties and assumptions and are not guarantees of future performance and may be affected by known and unknown risks, trends, uncertainties and factors that are beyond our control. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, estimated or projected. Some of the risks and uncertainties that may cause our actual results, performance or achievements to differ materially from those expressed or implied by forward-looking statements include, among others, the following:

• the impact of the recent deterioration in global economic, credit and market conditions, including the downgrading of the U.S. government’s credit rating;

• current local economic conditions in our geographic markets;

• decreases in information technology spending, including as a result of economic slowdowns or recession;

• 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);

• our dependence upon significant tenants;

• bankruptcy or insolvency of a major tenant or a significant number of smaller tenants;

• defaults on or non-renewal of leases by tenants;

• our failure to obtain necessary debt and equity financing;

• increased interest rates and operating costs;

• 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;

• financial market fluctuations;

• changes in foreign currency exchange rates;

• our inability to manage our growth effectively;

• difficulty acquiring or operating properties in foreign jurisdictions;

• our failure to successfully integrate and operate acquired or redeveloped properties;

• risks related to joint venture investments, including as a result of our lack of control of such investments;

• delays or unexpected costs in development or redevelopment of properties;

• decreased rental rates or increased vacancy rates;

• increased competition or available supply of data center space;

• our inability to successfully develop and lease new properties and space held for redevelopment;

• difficulties in identifying properties to acquire and completing acquisitions;

• our inability to acquire off-market properties;

• our inability to comply with the rules and regulations applicable to reporting companies;

• our failure to maintain our status as a REIT;

• possible adverse changes to tax laws;

• restrictions on our ability to engage in certain business activities;

• environmental uncertainties and risks related to natural disasters;

• losses in excess of our insurance coverage;

• changes in foreign laws and regulations, including those related to taxation and real estate ownership and operation; and

• changes in local, state and federal regulatory requirements, including changes in real estate and zoning laws and increases in real property tax rates.

The risks included here are not exhaustive, and additional factors could adversely affect our business and financial performance. We discussed a number of additional material risks in our annual report on Form 10-K for the year ended December 31, 2010, and other filings with the Securities and Exchange Commission. Those risks continue to be relevant to our performance and financial condition. 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 predict all such risk factors, nor can it 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. We expressly disclaim any responsibility to update forward-looking statements, whether as a result of new information, future events or otherwise.

(1) The market value of common equity is based on the closing stock price at the end of the quarter and assumes 100% redemption of the limited partnership units in our operating partnership, including common units and vested and unvested long-term incentive units (including vested and unvested class C units), for shares of our common stock. Excludes shares issuable with respect to stock options that have been granted but have not yet been exercised, and also excludes all shares potentially issuable upon exchange of our 5.50% exchangeable senior debentures due 2029 or upon conversion of our series C and series D cumulative convertible preferred stock.

(2) EBITDA is calculated as earnings before interest, taxes, depreciation and amortization. For a discussion of EBITDA, see page 31. For a reconciliation of net income available to common stockholders to EBITDA, see page 11.

(3) Adjusted EBITDA is EBITDA adjusted for preferred dividends and minority interests. For a discussion of Adjusted EBITDA, see page 31. For a reconciliation of net income available to common stockholders to Adjusted EBITDA, see page 11.

(4) Cash interest expense is interest expense per our statement of operations less amortization of debt discount and deferred financing fees and includes interest that we capitalized. For a reconciliation of GAAP interest expense to cash interest expense, see page 11.

(5) Fixed charges consist of cash interest expense, scheduled debt principal payments and preferred dividends.

(6) Debt service coverage ratio is Adjusted EBITDA divided by cash interest expense.

(7) Fixed charge coverage ratio is Adjusted EBITDA divided by fixed charges.

(8) For a definition and discussion of FFO, see page 31. For a reconciliation of net income available to common stockholders to FFO, see page 10.

(9) For a definition and discussion of AFFO, see page 31. For a reconciliation of FFO to AFFO, see page 10.

(10) Diluted FFO payout ratio is dividends declared per common share and unit divided by diluted FFO per share and unit.

(11) Diluted AFFO payout ratio is dividends declared per common share and unit divided by diluted AFFO per share and unit.

(12) Redevelopment space requires significant capital investment in order to develop data center facilities that are ready for use. Most often this is shell space. However, in certain circumstances this may include partially built datacenter space that was not completed by previous ownership and requires a large capital investment in order to build out the space.

(13) Occupancy and same store occupancy exclude space held for redevelopment. For some of our properties, we calculate occupancy based on factors in addition to contractually leased square feet, including available power, required support space and common area.

(14) Weighted average remaining lease term excludes renewal options, weighted by net rentable square feet.

(15) Same store properties were acquired before December 31, 2009.

For the three and nine months ended September 30, 2011, we have excluded the effect of dilutive series E preferred stock, that may be converted upon the occurrence of specified change in control transactions as described in the articles supplementary governing the series E preferred stock, which we consider highly improbable; if included, the dilutive effect for the three and nine months ended September 30, 2011 would be 914 and 308 shares, respectively. In addition, we had a balance of $266,400 of 5.50% exchangeable senior debentures that were exchangeable for 6,368 common shares on a weighted average basis for the three months ended September 30, 2011.

(a) Cash interest expense is interest expense less amortization of debt discount and deferred financing fees and includes interest that we capitalized. We consider cash interest expense to be a useful measure of interest as it excludes non-cash based interest expense.

(b) For a definition of Fixed Charges, see page 7.

(c) Adjusted EBITDA divided by interest expense.

(d) Adjusted EBITDA divided by fixed charges. Fixed charges include interest expense as per (a) above and scheduled debt principal payments and preferred dividends.

(e) Mortgage debt and other loans divided by mortgage debt and other loans plus the liquidation value of preferred stock and the market value of outstanding common stock and operating partnership units, assuming the redemption of operating partnership units for shares of our common stock.

(f) Same as (e), except numerator includes preferred stock.

(g) Calculated as income, including interest, divided by GAAP interest expense.

(h) Calculated as total debt at balance sheet carrying value (see page 7) less unrestricted cash and cash equivalents divided by Adjusted EBITDA multiplied by four.

(1) Annualized base rent represents the monthly contractual base rent (defined as cash base rent before abatements) under existing leases as of September 30, 2011 multiplied by 12. We estimate the total net rentable square feet available for lease based on a number of factors in addition to contractually leased square feet, including available power, required support space and common area.

(2) Occupancy excludes space held for redevelopment. For some of our properties, we calculate occupancy based on factors in addition to contractually leased square feet, including available power, required support space and common area.

(3) Includes approximately 33,700 rentable square feet from a leasehold interest acquisition.

(4) Net rentable square feet excludes square footage at two joint ventures: 2001 Sixth Avenue in Seattle, WA (400,369 rental square feet) which was 95.76% occupied and 700 -750 Central Expressway in Santa Clara, CA (306,144 rentable square feet) which was 100% occupied as of September 30, 2011.

(1) Includes license and similar agreements that upon expiration will be automatically renewed, mostly on a month-to-month basis. Number of leases represents the leased-unit count; a lease could include multiple units.

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

(3) Annualized base rent represents the monthly contractual base rent (defined as cash base rent before abatements) under existing leases as of September 30, 2011 multiplied by 12. We estimate the total net rentable square feet available for lease based on a number of factors in addition to contractually leased square feet, including available power, required support space and common area.

Third Quarter 2011

Management Statements on Non-GAAP Supplemental Measures

Funds from Operations:

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

Adjusted Funds from Operations:

We present adjusted funds from operations, or AFFO, as a supplemental operating measure because, when compared year over year, it assesses our ability to fund dividend and distribution requirements from our operating activities. We also believe that, as a widely recognized measure of the operations of REITs, AFFO will be used by investors as a basis to assess our ability to fund dividend payments in comparison to other REITs, including on a per share and unit basis. We calculate AFFO by adding to or subtracting from FFO (i) non-real estate depreciation, (ii) amortization of deferred financing costs, (iii) non-cash compensation, (iv) straight line rents, (v) fair value of lease revenue amortization, (vi) capitalized leasing payroll, (vii) recurring tenant improvements, (viii) capitalized leasing commissions and (ix) costs of redeeming our preferred stock. Other equity REITs may not calculate AFFO in a consistent manner. Accordingly, our AFFO may not be comparable to other REITs’ AFFO. AFFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.

EBITDA and Adjusted EBITDA:

We believe that earnings before interest expense, income taxes, depreciation and amortization, or EBITDA, and Adjusted EBITDA (as defined below), are useful supplemental performance measures because they allow investors to view our performance without the impact of non-cash depreciation and amortization or the cost of debt and, with respect to Adjusted EBITDA, preferred dividends and noncontrolling interests. Adjusted EBITDA is EBITDA excluding noncontrolling interests, preferred stock dividends and costs of redeeming our preferred stock. In addition, we believe EBITDA and Adjusted EBITDA are frequently used by securities analysts, investors and other interested parties in the evaluation of REITs. Because EBITDA and Adjusted EBITDA are calculated before recurring cash charges including interest expense and income taxes, exclude capitalized costs, such as leasing commissions, and are not adjusted for capital expenditures or other recurring cash requirements of our business, their utility as a measure of our performance is limited. Other REITs may calculate EBITDA and Adjusted EBITDA differently than we do; accordingly, our EBITDA and Adjusted EBITDA may not be comparable to such other REITs’ EBITDA and Adjusted EBITDA. Accordingly, EBITDA and Adjusted EBITDA should be considered only as supplements to net income computed in accordance with GAAP as a measure of our financial performance.

NOI:

Net Operating Income (NOI)

NOI represents rental revenue and tenant reimbursement revenue less rental property operating and maintenance expenses, property taxes and insurance expenses (as reflected in the statement of operations). NOI is commonly used by stockholders, company management and industry analysts as a measurement of operating performance of the company’s rental portfolio. However, because NOI excludes depreciation and amortization and captures neither the changes in the value of our properties that result from use or market conditions, nor the level of capital expenditures and capitalized leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effect and could materially impact our results from operations, the utility of NOI as a measure of our performance is limited. Other REITs may not calculate NOI in the same manner we do and, accordingly, our NOI may not be comparable to such other REITs’ NOI. Accordingly, NOI should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.
