Funds from operations (“FFO”) was $104.2 million for the year, or $1.63 on a diluted per share and unit basis, up 19.0% from $1.37 per diluted share and unit for the full year 2005. FFO was $33.0 million in the fourth quarter, or $0.48 on a diluted per share and unit basis, up 17.1% from $0.41 per diluted share and unit in the previous quarter; and up 33.3% from $0.36 per diluted share and unit in the fourth quarter of 2005.

Richard Magnuson, Chairman of Digital Realty Trust said “Digital Realty Trust delivered an exceptionally strong performance in 2006. We exceeded our expectations for acquisitions with $552.5 million of acquired properties and met the high-end of our estimate for leasing datacenter space with 300,000 square feet of leases commenced. Fueled by favorable market conditions, including strong demand for highly improved datacenter space in our markets, rental rates experienced exceptional growth during the year. The average annualized GAAP rent for datacenter space was over $91.00 per square foot. These acquisition and leasing results contributed to our growth in FFO.”

Acquisition and Leasing Activity

During the fourth quarter of 2006 the Company acquired seven properties totaling $205.4 million, including closing costs for the European assets. On October 1, 2006 the Company acquired the datacenter operations of AboveNet, which consists of three properties: one fee simple interest property in Reston, Virginia and two leaseholds in New York City and Vienna, Virginia. On October 6, 2006 the Company acquired 2055 East Technology Circle in Tempe, Arizona. The property is a vacant 76,400 square foot, two-story office and warehouse facility that was added to the Company’s portfolio of space held for redevelopment. On November 1, 2006 the Company acquired a partial interest in 2001 Sixth Avenue in Seattle, Washington, the primary hub for Internet traffic for the Pacific Northwest. This 34-story building totals 389,000 square feet, including 185,000 square feet of technical space. On December 5, 2006 the Company expanded its footprint in Europe with the acquisition of 114 Rue Ambroise Croizat in Paris, France. This property includes a 122,000 square foot income-producing datacenter and over 200,000 square feet available for redevelopment. In addition, on December 20, 2006 the Company acquired a 120,000 square foot datacenter facility, Unit 9, Blanchardstown Corporate Park, located in Dublin, Ireland.

Subsequent to the end of the year, the Company acquired three datacenter facilities. On January 5, 2007 the Company acquired 21110 Ridgetop Circle, a vacant 135,000 square foot shell datacenter located in Sterling, Virginia. Upon closing, the Company signed a lease with a leading managed service provider for the entire building. On January 22, 2007 the Company acquired 3011 Lafayette Street, a vacant 90,800 square foot shell datacenter located in Santa Clara, California. This property will be added to the Company’s inventory of space held for redevelopment. On February 27, 2007, the Company acquired 44470 Chillum Place, a single story datacenter facility located in Ashburn, Virginia. The property totals 95,400 square feet, including 65,600 square feet of raised floor, and is 100% leased to a leading network service provider through 2019

As of February 27, 2007, the Company’s portfolio comprised 63 properties consisting of 84 buildings totaling approximately 11.8 million rentable square feet, including 1.8 million square feet of space held for redevelopment. The portfolio is strategically located in 25 key technology markets throughout North America and Europe.

During the year, leases commenced on 300,000 square feet of datacenter space at an average annualized GAAP rent of over $91.00 per square foot, and over 155,000 square feet of non-technical space at an average annualized GAAP rental rate of $23.50 per square foot.

For the quarter ended December 31, 2006, leases commenced on 79,000 square feet of datacenter space at an average annualized GAAP rent of approximately $91.00 per square foot and 34,500 square feet of non-technical space at an average annualized GAAP rent of over $46.00 per square foot. The datacenter space leased during the quarter includes 22,000 square feet of redevelopment space at an average annualized GAAP rent of approximately $25.00 per square foot. Excluding space held for redevelopment, occupancy across Digital Realty’s property portfolio was 95.0% at December 31, 2006. Of the 411,000 square feet of new leases signed during the fourth quarter, more than 302,000 square feet of datacenter space and 7,700 square feet of non-technical space will commence in 2007.

“2006 was a great year for Digital Realty Trust and we are continuing to see strong demand from national and international corporate users for datacenter space that can meet today’s power and cooling requirements. Important trends driving this demand include increased regulatory and legislative requirements for business continuity and record retention, disaster recovery initiatives along with significant growth in online advertising and e-commerce spending. We are well-positioned to meet this demand through our redevelopment program, acquisition pipeline and leasing momentum. We currently have construction projects underway in eleven key technology markets throughout the U.S. and Europe that will add over 500,000 rentable square feet of build-to-suit and Turn-Key Datacenter™ space. We have expanded our presence in Europe with the addition of the Paris property, a second operating datacenter facility in Dublin and the development of a new 120,000 datacenter at the site of our first Dublin property. We are also expanding our presence in select U.S. markets including Northern Virginia, and now own five properties there totaling approximately 338,000 square feet and one property under contract that will more than double our square footage in this important market for information technology and Internet communications,” said Michael Foust, Chief Executive Officer of Digital Realty Trust. “The volume of

leasing activity and strong growth in rents are the results of our proven ability to acquire and deliver highly improved datacenter space for national and international corporate users that depend on our reliable, cost effective solutions for their datacenter requirements.”

Balance Sheet Update

Total assets grew to approximately $2.2 billion at December 31, 2006, from $1.5 billion at December 31, 2005. Total debt at December 31, 2006 was approximately $1.1 billion compared to $749.1 million at December 31, 2005. Stockholders’ equity was $709.8 million, up from $386.5 million at December 31, 2005, primarily due to the redemption of operating units for common stock and two follow-on public offerings, which generated $228.3 million in net proceeds that were used to reduce borrowings under the Company’s credit facility.

In addition to increasing commitments under its credit facility in the third quarter of 2006 from $350 million to $500 million, during the fourth quarter the Company amended the financial covenants to enhance the Company’s financial flexibility and include redevelopment assets in the borrowing base.

The Company completed mortgage financings during the quarter on one property in Northern California and two properties in Europe. On October 24, 2006 the Company completed the financing of 1100 Space Park Drive in Santa Clara, California. The new loan for $55 million has a 10-year maturity with no principal amortization for three years, and a fixed rate of 5.89%. On December 5, 2006 the Company completed the secured financing of 114 Rue Ambroise Croizat in Paris, France. The new loan for 32.8 million Euros (equal to $43.3 million at December 31, 2006) closed simultaneously with the acquisition and has a five year maturity with a swapped fixed rate of 5.13%. On December 20, 2006 the Company completed the secured financing of the Blanchardstown Corporate Park property in Dublin, Ireland. The new loan for 28.2 million Euros (equal to $37.2 million at December 31, 2006) closed simultaneously with the acquisition and has a 5-year maturity at a swapped fixed rate of 5.35%.

Subsequent to year-end on January 31, 2007, the Company completed the financing of 2045 & 2055 Lafayette Street in Santa Clara, California. This $68.0 million loan has a 10-year maturity with no principal amortization for two years and a fixed rate of 5.93%. On February 2, 2007 the Company completed the financing of 150 South First Street in San Jose, California. This $53.3 million loan has a 10-year maturity with no principal amortization for two years and a fixed rate of 6.30%.

“Our strong performance in 2006 was facilitated by our ability to successfully access debt and equity markets. We raised approximately $900 million during the year from our increased credit facility, mortgage financings and refinancings, as well as registered debt and equity offerings,” said A. William Stein, Chief Financial Officer and

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.
