Digital Realty Trust, Inc. Reports First Quarter 2008 Results

May 8, 2008

SAN FRANCISCO, May 8 /PRNewswire-FirstCall/ -- Digital Realty Trust, Inc. (NYSE: DLR), the leading owner and manager of corporate and Internet gateway datacenter facilities, today announced financial results for its first quarter ended March 31, 2008. The Company reported operating revenue of $114.5 million in the first quarter of 2008. For the first quarter of 2008, net income was $11.1 million and net income available to common stockholders was $2.9 million, or $0.04 per diluted share. This compares to net income in the fourth quarter of 2007 of $5.6 million and net income available to common stockholders of $0.3 million, or $0.00 per diluted share, and net income in the first quarter of 2007 of $22.1 million and net income available to common stockholders of $18.6 million, or $0.32 per diluted share. Excluding the gain on sale of $18.0 million and related minority interests, net income available to common stockholders in the first quarter of 2007 would have been approximately $3.6 million or $0.06 per diluted share.

Funds from operations ("FFO") was $43.0 million in the first quarter in 2008, or $0.58 on a diluted per share and unit basis, up 9.4% from $0.53 per diluted share and unit in the previous quarter; and up 16.0% from $0.50 per diluted share and unit in the first quarter of 2007. FFO is a supplemental non-GAAP financial measure used by the real estate industry to measure the operating performance of real estate companies. FFO should not be considered as a substitute for net income determined in accordance with U.S. GAAP as a measure of financial performance. A reconciliation from U.S. GAAP net income available to common stockholders to FFO and a definition of FFO are included as an attachment to this press release.

"Our exceptional performance in the first quarter of 2008 reflects our ability to meet the strong demand for datacenter space even under challenging economic conditions. We are continuing to experience demand from customers across a variety of industry sectors, including financial services, Internet enterprise, system integrators and Fortune 1000 companies, for both our Turn- Key Datacenter(TM) and Powered Base Building(TM) solutions," commented Michael F. Foust, Chief Executive Officer of Digital Realty Trust. "In addition, we recently completed a new research study which indicates a significant increase in the number of datacenter projects planned by U.S. corporations during the coming 12 months. The detailed results of this study will be made available in a separate press release to be issued later today."

"The $0.58 of FFO per diluted share and unit includes approximately $0.02 of additional FFO from non-recurring items," added A. William Stein, Chief Financial Officer and Chief Investment Officer of Digital Realty Trust. "We continue to maintain a strong balance sheet and currently have $474.8 million of immediate liquidity under our revolving credit facility and the ability to borrow an additional $250.0 million as secured debt to fund our planned expenditures to grow the Company. Because of the results of our leasing activities and a reduction in expected G&A expenses, we are increasing our FFO guidance for 2008 by $0.05 per share."

Acquisition and Leasing Activity

On February 14, 2008, the Company acquired 365 South Randolphville Road, a 265,000 square foot redevelopment project located in Piscataway, New Jersey, adjacent to the Company's 3 Corporate Place facility. The newly acquired property is capable of supporting up to 150,000 square feet of technical datacenter space. The Company intends to make base building improvements and upgrade power to the building with initial plans to build-out two Turn-Key Datacenters(TM), totaling approximately 20,000 square feet of raised floor.

The Company is expecting to complete during the next week the acquisition of 650 Randolph Road in Franklin Township, New Jersey. The recently completed purpose-built datacenter shell totals 127,800 square feet, which is capable of supporting approximately 70,000 square feet of raised floor. The Company plans to contribute the property to its redevelopment inventory and make additional improvements to the building to meet its Powered Base Building(TM) specifications. Upon completion of the base building improvements, the Company plans to market the facility to financial service companies, system integrators and other Fortune 1000 companies looking for large blocks of high quality datacenter space in the Metro New York market.

As of May 8, 2008, the Company's portfolio comprises 71 properties, excluding one property held in a consolidated joint venture, consisting of 93 buildings totaling approximately 12.7 million rentable square feet, including 1.9 million square feet of space held for redevelopment. The portfolio is strategically located in 26 key technology markets throughout North America and Europe.

The Company commenced leases during the quarter totaling approximately 334,800 square feet of space. This includes 256,200 square feet of Turn-Key Datacenter(TM) space leased at an average annual GAAP rental rate of $119.25 per square foot, 46,300 square feet of Powered Base Building(TM) space leased at an average annual GAAP rental rate of $52.42 per square foot, and 32,300 square feet of non-technical space leased at an average annual GAAP rental rate of $19.31 per square foot.

In addition, the Company signed leases during the quarter totaling 260,200 square feet of space. This includes 106,400 square feet of Turn-Key Datacenter(TM) space leased at an average annual GAAP rental rate of $100.05 per square foot, nearly 120,000 square feet of Powered Base Building(TM) space leased at an average annual GAAP rental rate of $67.60 per square foot, and 33,800 square feet of non-technical space leased at an average annual GAAP rental rate of $25.93 per square foot.

Balance Sheet Update

Total assets grew to approximately $2.9 billion at March 31, 2008, from $2.8 billion at December 31, 2007. Total debt at March 31, 2008 was approximately $1.2 billion compared to $1.4 billion at December 31, 2007. Stockholders' equity was approximately $1.4 billion, up from $1.0 billion at December 31, 2007, primarily due to the public offering of Series D Cumulative Convertible Preferred Stock.

On February 6, 2008 the Company completed a public offering of 13,800,000 shares of Series D Cumulative Convertible Preferred Stock, including the over- allotment option that was exercised, which generated approximately $333.6 million in net proceeds. The Company utilized the net proceeds from the offering to temporarily repay borrowings under its revolving credit facility, to fund acquisitions, development and redevelopment activities, and for general corporate purposes. The Series D Cumulative Convertible Preferred Stock pays dividends quarterly at a rate of 5.500% per year on its $25.00 liquidation preference. The Series D Cumulative Convertible Preferred Stock is convertible, at the holder's option, at an initial conversion rate of 0.5955 common shares per $25.00 liquidation preference (or an initial conversion price of $41.98 per common share), subject to adjustment upon the occurrence of certain events. The initial conversion price represents a 17.5% conversion premium over the closing sale price of the Company's common shares on the New York Stock Exchange on January 31, 2008, the day the offering was priced, which was $35.73 per share.

2008 Revised Outlook

FFO per diluted share and unit for the year ending December 31, 2008 is projected to be between $2.35 and $2.45, increasing from the previous 2008 FFO guidance of between $2.30 and $2.40 per diluted share and unit. This revised guidance represents projected FFO growth of 14.6% to 19.5% over FFO per diluted share and unit of $2.05 for the year ended December 31, 2007. A reconciliation of the range of 2008 projected net income to projected FFO follows:

                                                          (Low - High)
    Net income available to common stockholders
     per diluted share                                    $0.40 - 0.50
        Add:
    Minority interest                                        $0.02
    Real estate depreciation and amortization                $1.93
    Projected FFO per diluted share                       $2.35 - 2.45

The revised 2008 guidance provided by Digital Realty Trust in this press release is based on the following assumptions as of May 8, 2008:

    -- Total acquisitions for the full year in the range of $125 million to
       $185 million, consisting of $65 million to $75 million of vacant
       properties for its redevelopment program and $60 million  to $110
       million of income producing properties at average cash cap rate of
       8.00%;
    -- The commencement of leases for approximately 890,000 square feet to
       990,000 square feet of Turn-Key Datacenter(TM) and Powered Base
       Building(TM) space at an average annualized gross rent of $90 per
       square foot;
    -- The commencement of leases for 100,000 square feet to 125,000 square
       feet of basic commercial space at an average annualized gross rent of

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.
