MENLO PARK, Calif., May 11 /PRNewswire-FirstCall/ -- Digital Realty Trust, Inc. (NYSE: DLR) today announced financial results for its first quarter ended March 31, 2005. The Company reported revenue of $39.6 million in the first quarter of 2005. Net income for the first quarter of 2005 was $2.7 million and net income available to common stockholders was $1.5 million, or $0.07 per diluted share. Funds from operations (FFO) for the three months ended March 31, 2005 was $15.8 million, or $0.30 per diluted share and unit.

The Company commenced operations on November 3, 2004, and as such, comparisons to the prior year period have not been included in this press release. Financial results for Digital Realty Trust's predecessor for the first quarter of 2004 will be available in the Company's Form 10-Q for the three month period ended March 31, 2005, as filed with the Securities and Exchange Commission on or before May 16, 2005.

"Our first full quarter as a public company was extremely rewarding," said Richard Magnuson, Executive Chairman of Digital Realty Trust. "We reported strong financial results, and expect to reach our full-year acquisition target during the second quarter of 2005, well ahead of schedule. By maintaining our focus on the acquisition, management and leasing of highly specialized, technology-related properties, we believe Digital Realty Trust will continue to benefit from improving marketplace trends."

Balance Sheet Update

Total assets grew to $1.1 billion at March 31, 2005, from $1.0 billion at December 31, 2004. Cash and cash equivalents were $2.9 million at March 31, 2005 compared to $4.6 million at December 31, 2004. The reduction in cash was primarily due to the acquisition of properties in Philadelphia, Pennsylvania and St. Paul , Minnesota combined with effective working capital management. Total debt at March 31, 2005 was $515.7 million and stockholders' equity was $269.6 million, up from $173.2 million at December 31, 2004.

During the first quarter of 2005, Digital Realty Trust completed a preferred stock offering, generating gross proceeds of $103.5 million. The proceeds were used to repay borrowings under the Company's existing line of credit, acquire properties and for other corporate purposes.

"Our balance sheet remains strong and the Company is well capitalized," said A. William Stein, Chief Financial Officer and Chief Investment Officer of Digital Realty Trust. "Approximately 80% of our total debt is fixed, and, including extension options, we have no significant maturities until 2008. Importantly, the preferred stock offering which we completed in February, combined with an amended credit facility, provides us access to additional capital to successfully execute our growth strategy."

Acquisition and Leasing Activity

Acquisition and leasing activity since the beginning of the year has been substantial. This will allow Digital Realty Trust to meet its 2005 full year acquisition and highly improved technology space lease-up targets ahead of schedule.

The Company acquired two properties for a total of $74.6 million in the first quarter of 2005, and placed two additional properties, the Lakeside Technology Center and Printers' Square, both located in Chicago, under contract for an additional $180.1 million. The Lakeside Technology Center acquisition is expected to close during the second quarter of 2005, and the Company is continuing its due diligence on the Printers' Square property. During the quarter, the Company also purchased the remaining 25% interest in the eBay Data Center, a 62,957 square foot data center located in Rancho Cordova, California, and now owns 100% of that property. Upon closing the Lakeside Technology Center acquisition, the portfolio will comprise 27 properties consisting of approximately 7.2 million net rentable square feet, excluding space held for redevelopment, strategically located in 14 key technology markets throughout the United States, with one property located in London, England.

Year-to-date through April 30, 2005, Digital Realty Trust has leased approximately 23,200 square feet of highly improved, technology space and more than 17,000 square feet of basic commercial space. Excluding space held for redevelopment, occupancy across Digital Realty's property portfolio was approximately 88.9% at March 31, 2005.

"The Digital Realty Trust team has made considerable progress against our acquisition and leasing goals for 2005, significantly enhancing our portfolio," said Michael Foust, Chief Executive Officer of Digital Realty Trust. "The buildings we've acquired, or plan to acquire, fit well with our growth strategy of targeting high quality, strategically located properties that contain applications and operations critical to the day-to-day operations of corporate enterprise data center and technology industry tenants. In addition, the acquisitions further improve the diversity of our portfolio, both geographically and by tenant.

"We have also been very successful in our leasing activity since the start of the year, having rented out a large portion of highly improved technology space in the San Francisco market at an initial gross rent of approximately $60 per rentable square foot. As we move through the remainder of 2005, the Company will be focused on both organic growth and growth through acquisition, by identifying additional assets that complement our portfolio while aggressively managing and leasing current assets to maximize their cash flow."

2005 Outlook

Digital Realty Trust's management increased its 2005 outlook as follows: FFO per share for the year ending December 31, 2005 is expected to be between $1.35 and $1.40. A reconciliation of the range of 2005 projected net income to projected FFO follows:

FFO should not be considered as a substitute for net income (loss) determined in accordance with GAAP as a measure of financial performance. A reconciliation from GAAP net income to FFO is included as an attachment to this press release.

    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) (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, 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.
