DIGITAL REALTY TRUST, INC. REPORTS SECOND QUARTER FFO OF $1.09 PER

SHARE, UP 2.8% FROM FIRST QUARTER 2012

Company updates 2012 FFO and core FFO guidance, increasing core FFO midpoint

San Francisco, Calif. (July 25, 2012) – Digital Realty Trust, Inc. (NYSE: DLR), a leading global provider of data center solutions, today announced financial results for the second quarter of 2012. All per share results are on a diluted share and unit basis.

Recent Highlights:

Funds from operations (“FFO”) was $136.9 million in the second quarter of 2012, or $1.09 per share, up 2.8% from $1.06 per share in the previous quarter and up 6.9% from $1.02 per share in the second quarter of 2011.

“Adjusting for items that do not represent ongoing expenses or revenue streams, second quarter 2012 core FFO was $1.07 per share, up 0.9% from first quarter 2012 core FFO of $1.06 per share and up 4.9% from second quarter 2011 core FFO of $1.02 per share,” said A. William Stein, Chief Financial Officer and Chief Investment Officer of Digital Realty. “The $0.02 per share decrease in core FFO compared to reported FFO was primarily due to termination fees that were partially offset by transaction and other expenses.”

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 are included as an attachment to this press release.

Net income for the second quarter of 2012 was $54.0 million, compared to $49.3 million for the first quarter of 2012 and $38.2 million for the second quarter of 2011. Net income available to common stockholders in the second quarter of 2012 was $42.0 million, or $0.38 per share, compared to $39.2 million, or $0.36 per share, in the first quarter of 2012, and $32.0 million, or $0.33 per share, in the second quarter of 2011.

The Company reported total operating revenues of $303.7 million in the second quarter of 2012, up 7.3% from $283.1 million in the first quarter of 2012, and up 13.4% from $267.9 million in the second quarter of 2011.

“We are extremely pleased with our performance to date this year. In addition to our solid financial and leasing results, we completed several landmark acquisitions, including the Sentrum Portfolio in London, our first property in Hong Kong with our joint venture partner Savvis, and a major redevelopment property in suburban Chicago,” said Michael F. Foust, Chief Executive Officer of Digital Realty. “We believe that the depth of our team combined with our financial strength and ability to access attractively priced capital to fund our growth are key differentiators for us. These core capabilities along with our focus on delivering flexible, customer driven data center solutions continue to drive value for our shareholders.”

Acquisitions Activity

In the second quarter of 2012, Digital Realty and Savvis, a CenturyLink company, acquired a 164,000-square-foot (15,236-square-meter) property in Hong Kong, which is held in an unconsolidated joint venture. The property is located at Tseung Kwan O Industrial Estate in New Territories, approximately 12 miles from downtown Hong Kong. Upon redevelopment, the building will be capable of supporting approximately 5.76 megawatts of IT load capacity, with potential to add up to 2.9 megawatts of additional capacity.

In the second quarter of 2012, the Company completed three property acquisitions:

Subsequent to the end of the quarter, on July 11, 2012, the Company completed the acquisition of a three-property portfolio totaling approximately 761,000 square feet located in the greater London area, referred to as the Sentrum Portfolio. The purchase price was £715.9 million (equivalent to $1.1 billion based on the July 11, 2012 exchange rate of £1.00 to $1.55) (subject to adjustment in limited circumstances and to earn-out payments). The acquisition was funded with proceeds from our follow-on equity offering which closed on July 2, 2012 and borrowings under the global revolving credit facility.

As of July 25, 2012, the Company’s portfolio comprised 108 properties, excluding three properties held in unconsolidated joint ventures, consisting of 103 data center facilities and 5 non-technical buildings totaling approximately 20.8 million net rentable square feet, including 2.3 million square feet of space held for redevelopment. The portfolio is strategically located in 32 key data center markets throughout North America, Europe, Asia and Australia.

Balance Sheet Update

Total assets grew to approximately $6.7 billion at June 30, 2012 from $6.4 billion at March 31, 2012. Total debt increased to $3.4 billion at June 30, 2012 from $3.3 billion at March 31, 2012. Stockholders’ equity was approximately $2.7 billion at June 30, 2012, up slightly from approximately $2.6 billion at March 31, 2012.

On April 5, 2012 and April 18, 2012, the Company completed an underwritten public offering of 7,300,000 shares of its 6.625% Series F Cumulative Redeemable Preferred Stock, par value $0.01 per share, including partial exercise of the underwriters’ over-allotment option, for net proceeds of approximately $176.3 million after deducting underwriting discounts and commissions and offering expenses.

On April 17, 2012, the Company closed a new $750 million U.S. dollar equivalent Senior Unsecured Multicurrency Term Loan. The term loan matures in April 2017. Pricing is based on the Company’s senior unsecured debt ratings and is currently 145 basis points over the applicable index for floating rate advances. Funds have been drawn in U.S, Singapore and Australian dollars, as well as Euro and Pound Sterling denominations with the option to add Hong Kong dollars and Yen upon exercise of the $100 million U.S. dollar equivalent accordion. Covenants are consistent with our global revolving credit facility. Proceeds from the term loan were used to repay amounts outstanding under the global revolving credit facility.

On July 2, 2012, the Company completed an offering of 11,500,000 shares of its common stock, including 1,500,000 shares issued upon exercise of the underwriters’ option to purchase additional shares, which was exercised in full, at a price of $72.25 per share, for net proceeds of approximately $796.8 million after deducting underwriting discounts and commissions and offering expenses. Proceeds from the offering were used to fund a portion of the purchase price of the Sentrum Portfolio and repay amounts outstanding under the global revolving credit facility.

2012 Revised Outlook

“The original guidance range of $4.34 to $4.48 per share assumed that items that did not represent ongoing revenue and expense streams would net out to zero over the course of the year. Therefore, core FFO and reported FFO would be essentially identical. As a result of the transaction costs, including debt extinguishment costs associated with the Sentrum acquisition, core FFO will now be significantly greater than reported FFO in 2012,” said Mr. Stein.

FFO per share for the year ending December 31, 2012 is projected to be between $4.15 and $4.25. This guidance represents expected FFO growth of 2.2% to 4.7% over 2011 FFO of $4.06 per share. After adjusting for certain items that do not represent core revenue and expense streams for the full years 2012 and 2011, core FFO per share for the year ending December 31, 2012 is projected to be between $4.37 and $4.48, which represents expected core FFO growth of 6.8% to 9.5% over 2011 core FFO of $4.09 per share. A reconciliation of the range of 2012 projected net income to projected FFO and core FFO follows:

The 2012 guidance provided by Digital Realty in this press release is based on the following updated assumptions as of July 25, 2012:

Note Regarding Funds From Operations

Digital Realty 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, impairment charges, real estate related depreciation and amortization (excluding amortization of deferred financing costs) and after adjustments for unconsolidated partnerships and joint ventures. Management uses FFO as a supplemental performance measure because, in excluding real estate related depreciation and amortization and gains and losses from property dispositions, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. Digital Realty 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 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.
