SAN FRANCISCO, Aug. 7 /PRNewswire-FirstCall/ -- Digital Realty Trust, Inc. (NYSE: DLR), a leading owner and manager of corporate datacenters and Internet gateway facilities, today announced financial results for its second quarter ended June 30, 2007. The Company reported operating revenue of $95.6 million in the second quarter of 2007. Net income for the second quarter of 2007 was $7.8 million and net income available to common stockholders was $2.6 million, or $0.04 per diluted share, compared to $18.6 million, or $0.32 per diluted share and unit, in the previous quarter (which included an $18.0 million gain on sale and related minority interests), and $1.7 million, or $0.05 per diluted share and unit, for the second quarter of 2006. Funds from operations ("FFO") was $35.6 million in the second quarter, or $0.51 per diluted share and unit, up 2% from $35.0 million, or $0.50 per diluted share and unit in the previous quarter; and up 34% from $0.38 per diluted share and unit in the second quarter of 2006.

Acquisition and Leasing Activity

During the second quarter of 2007 the Company completed the acquisition of a 9.4 acre development site in suburban London, England -- which the Company considers to be one of the most supply-constrained markets for datacenter space worldwide. Digital Realty Trust negotiated a power contract with the regional utility company that provisions the site with greatly expanded electrical service. The Company has executed a contract with a global financial institution to construct a build-to-suit datacenter on the site.

As of August 7, 2007, the Company's portfolio comprises 62 properties, excluding one property held as an investment in an unconsolidated joint venture, consisting of 83 buildings totaling approximately 11.4 million rentable square feet, including 1.7 million square feet of space held for redevelopment. The portfolio is strategically located in 25 key technology markets throughout North America and Europe. Excluding space held for redevelopment, occupancy across Digital Realty Trust's property portfolio was 94.6% at June 30, 2007.

For the quarter ended June 30, 2007, leases commenced on approximately 61,700 square feet of datacenter space at an average annualized rent of approximately $110.00 per square foot. The Company also commenced leases on 14,500 square feet of non-technical space at an average annualized rent of approximately $22.00 per square foot. The 274,700 square feet of leases signed during the second quarter includes over 228,400 square feet of datacenter space at an average annualized rent of approximately $72.00 per square foot and 46,300 square feet of non-technical space at an average annualized rent of approximately $22.00 per square foot.

Over 404,400 square feet of redevelopment space was under construction during the quarter, consisting of 240,000 square feet of Turn-Key Datacenter(TM), 39,900 square feet of build-to-suit datacenter and 124,500 square feet of new Powered Base Building(TM) building. Approximately 56,400 square feet space held for redevelopment was converted to the operating portfolio during the second quarter of 2007, which includes 37,700 square feet of Turn-Key Datacenter(TM) as well as 18,700 square feet of space that was leased on a Powered Base Building(TM) basis.

"New corporate applications, regulatory requirements for business continuity and data storage, as well as the proliferation of content distributed via the Internet are among the leading factors that continue to drive demand for high quality datacenter space. As a result, datacenters have become a critical infrastructure component of the global economy," said Michael Foust, Chief Executive Officer of Digital Realty Trust. "Our strong performance is a reflection of our ability to satisfy this demand for space while offering tenants across industry verticals customer-oriented solutions that meet their current and long-term datacenter requirements. Our business fundamentals are solid and we are on track to meet or exceed our goals for the year."

Balance Sheet Update

Total assets grew to approximately $2.4 billion at June 30, 2007, from $2.2 billion at December 31, 2006. Total debt at June 30, 2007 was approximately $1.2 billion compared to $1.1 billion at December 31, 2006. Stockholders' equity was $936.5 million, up from $709.8 million at December 31, 2006, primarily due to the issuance of 7.0 million shares of Series C Cumulative Convertible Preferred Stock completed during the quarter resulting in approximately $169.1 million in net proceeds.

On April 10, 2007 the Company completed the underwritten public offering of 7 million shares of Series C Cumulative Convertible Preferred Stock. The Series C Cumulative Convertible Preferred Stock will pay dividends quarterly at a rate of 4.375% per annum of the $25 liquidation preference per share. The preferred shares will be convertible, at the holder's option, at an initial conversion rate of 0.5164 common shares per $25.00 liquidation preference per preferred share (or an initial conversion price of $48.41 per common share), subject to adjustment upon the occurrence of certain events. The initial conversion price represents a 20% conversion premium over the closing sale price of the Company's common shares on April 3, 2007, which was $40.34 per share.

During the quarter the Company also closed a construction financing on 3 Corporate Place in Piscataway, New Jersey. This $70.0 million construction loan has an 18-month maturity with a six-month extension option and a rate of one-month LIBOR + 225 basis points.

"We are continuing to manage our balance sheet to minimize our cost of capital, given the current market conditions, while maintaining financial flexibility to fund our growth," said A. William Stein, Chief Financial Officer and Chief Investment Officer of Digital Realty Trust.

The Company is not changing its 2007 guidance at this time.

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 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.
