Other revenues in the second quarter of 2005 totaled $3.9 million, which included a $2.5 million lease termination payment received in cash and $1.1 million of non-cash revenue from the reversal of the recorded liability for the unamortized balance of the acquired below market lease intangible related to the terminated lease, both recognized following the early termination of a tenant lease. Other expenses in the second quarter of 2005 were $1.0 million, comprised mainly of a $0.9 million non-cash expense for assets written off following the early lease termination mentioned above.

For the first six months of 2005, Digital Realty Trust reported revenue of $89.3 million. Net income for the first six months of 2005 was $7.1 million, and net income available to common stockholders was $3.6 million, or $0.17 per diluted share.

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 second quarter and first six months of 2004 will be available in the Company’s Form 10-Q for the three and six month periods ended June 30, 2005, as filed with the Securities and Exchange Commission on or before August 15, 2005.

“We had another very strong showing this quarter,” said Richard Magnuson, Executive Chairman of Digital Realty Trust. “As trends in our marketplace improve, our team continues to execute well against our business strategy. As a result, we expect to further solidify our position as the leading owner and operator of mission-critical, technology-related real estate.”

Balance Sheet Update

Total assets grew to $1.4 billion at June 30, 2005, from $1.0 billion at December 31, 2004. Cash and cash equivalents were $4.0 million at June 30, 2005 compared to $4.6 million at December 31, 2004.

Subsequent to the end of the second quarter of 2005, Digital Realty Trust completed two successful equity offerings, including a follow-on common stock offering and a series B preferred stock offering. Both offerings were oversubscribed and the common stock offering was upsized by 20%. The over-allotment options on both offerings were also fully exercised. The gross proceeds of approximately $167.8 million were used to repay borrowings under the Company’s revolving credit facility.

“Our recently completed equity offerings provide us with significant growth capital,” said A. William Stein, Chief Financial Officer and Chief Investment Officer of Digital Realty Trust. “At the end of June, pro forma for the equity offerings described above and using our closing share price on August 9th, our ratio of total debt to total enterprise value is 32.3% and our total availability under the revolving credit facility is $163 million. Approximately 85% of our total debt is fixed and our maturity schedule remains attractive, with no significant maturities over the next five years, including extension options. The strong financial position we’ve built enhances our ability to implement our long-term growth initiatives.”

Acquisition and Leasing Activity

The Company met its original full-year 2005 acquisition targets in the second quarter of 2005. In anticipation of meeting this target well ahead of schedule, Digital Realty Trust increased its full-year 2005 acquisition and leasing objectives on May 11, 2005. At that time, the Company said it was expecting full year 2005 property acquisitions to be in the range of $300 to $350 million, lease-up of basic commercial space to be in the range of 150,000 to 200,000 square feet, and lease-up of highly improved technology space to be approximately 40,000 square feet.

The Company acquired seven properties in the second quarter of 2005 for a total of approximately $250.6 million. The acquired properties include the Lakeside Technology Center, one of Chicago’s premier Internet gateway and data centers, a Denver-area data center fully-leased to Ameriquest Mortgage Company, and four mission-critical data centers and one office building located in Northern and Southern California, fully-leased to Savvis, Inc. Including these acquisitions, Digital Realty Trust has acquired nine properties for a total of approximately $325.2 million since the beginning of 2005.

Year-to-date through July 31, 2005, Digital Realty Trust has leased more than 35,000 square feet of highly improved technology space at an average annualized rent of more than $92.00 per square foot and more than 161,500 square feet of basic commercial space at an average annualized rent of almost $19.50 per square foot.

Excluding space held for redevelopment, occupancy across Digital Realty’s property portfolio was approximately 89.7% at June 30, 2005, up from 88.9% at March 31, 2005.

“Acquisition and leasing activity is a top priority for us, and our success has enhanced the overall quality of our real estate portfolio,” said Michael Foust, Chief Executive Officer of Digital Realty Trust. “Since the beginning of the year, we’ve added 2.1 million square feet of space in nine properties. In line with our business plan, this growth has further diversified our asset base, either by tenant, geography, or both. Future acquisitions are a key element of our growth strategy. At the same time, we plan to aggressively manage and lease all of our assets to maximize their cash flow and enhance shareholder value.”

2005 Outlook

Digital Realty Trust reiterated its 2005 outlook as follows: FFO per share and unit 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:

(in millions, except share and unit data)	Low end of range			High end of range
Net income	$	11.3		$	12.7
Plus: Minority interest in operating partnership	$	13.5		$	15.2
Net income before minority interest in operating partnership but after minority interest in consolidated joint ventures	$	24.8		$	27.9
Plus: Real estate related depreciation and amortization		60.1			60.1
Funds from operations	$	84.9		$	88.0
Less: Preferred stock dividends		(10.1	)		(10.1	)

FFO per share of common stock and unit outstanding	$	1.35		$	1.40

The guidance provided by Digital Realty Trust in this press release is based on the following full-year 2005 assumptions as of August 9, 2005:

• Total acquisitions in the range of $450.0 million to $500.0 million, at an average cap rate of 8.75% to 9.25%.

• The lease-up of 200,000 square feet of basic commercial space at an average gross rent of $20.00 per square foot.

• The lease-up of approximately 45,000 to 50,000 square feet of highly improved technology space at an average gross rent of $60.00 per square foot.

Management Note Regarding FFO Presentation

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 (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.

This supplemental package contains forward-looking statements within the meaning of the federal securities laws. Such statements are based on management’s beliefs and assumptions made based on information currently available to management. Such statements are subject to risks, uncertainties and assumptions and are not guarantees of future performance and may be affected by known and unknown risks, trends, uncertainties and factors that are beyond our control. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, estimated or projected. Some of the risks and uncertainties that may cause our actual results, performance or achievements to differ materially from those expressed or implied by forward-looking statements include, among others, the following: adverse economic or real estate developments in our markets or the technology industry; general and local economic conditions; defaults on or non-renewal of leases by tenants; increased interest rates and operating costs; our inability to manage growth effectively; our failure to obtain necessary outside financing; decreased rental rates or increased vacancy rates; difficulties in identifying properties to acquire and completing acquisitions; our failure to successfully operate acquired properties and operations; our failure to maintain our status as a REIT; possible adverse changes to tax laws; environmental uncertainties and risks related to natural disasters; financial market fluctuations; changes in foreign currency exchange rates; and changes in real estate and zoning laws and increases in real property tax rates. The risks included here are not exhaustive, and additional factors could adversely affect our business and financial performance. We discussed a number of additional material risks in our annual report on Form 10-K for the year ended December 31, 2004 and other filings with the Securities and Exchange Commission. Those risks continue to be relevant to our performance and financial condition. Moreover, we operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time and it is not possible for management to predict all such risk factors, nor can it assess the impact of all such risk factors on the business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. We expressly disclaim any responsibility to update forward-looking statements, whether as a result of new information, future events or otherwise.

⁽¹⁾ Annualized rent represents the annualized monthly contractual rent under existing leases as of June 30, 2005. This amount reflects total base rent before any one-time or non-recurring rent abatements, but after annually recurring rent credits and is shown on a net basis; thus, for any tenant under a partial gross lease, the expense stop, or under a full gross lease, the current year operating expenses (which may be estimates as of such date), are subtracted from gross rent.

⁽²⁾ The properties at Lakeside Technology Center and 833 Chestnut Street have an additional 290,000 and 107,563 square feet, respectively of vacant space held for redevelopment. The occupancy percentage presented excludes the space available for redevelopment.

MANAGEMENT STATEMENTS ON NON-GAAP SUPPLEMENTAL MEASURES

Funds from Operations:

We calculate 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. We also believe 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.

Adjusted Funds From Operations:

We present adjusted funds from operations, or AFFO, as a supplemental operating measure because, when compared year over year, it assesses our ability to fund dividend and distribution requirements from our operating activities. We also believe that, as a widely recognized measure of the operations of REITs, AFFO will be used by investors as a basis to assess our ability to fund dividend payments in comparison to other REITs. We calculate adjusted funds from operations, or AFFO, by adding to or subtracting from FFO (i) non-real estate depreciation, (ii) amortization of deferred financing costs (iii) noncash compensation (iv) loss from early extinguishment of debt (v) straight line rents (vi) fair valule of lease revenue amortization (vii) capitalized leasing payroll (viii) recurring tenant improvements and (ix) capitalized leasing commissions. Other equity REITs may not calculate AFFO in a consistent manner. Accordingly, our AFFO may not be comparable to other equity REITs’ AFFO. AFFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our operations.

EBITDA:

We believe that earnings before interest, income taxes, depreciation and amortization, or EBITDA, is a useful supplemental performance measure. Management uses EBITDA as an indicator of our ability to incur and service debt. We believe EBITDA is an appropriate supplemental measure for such purposes, because the amounts spent on interest are, by definition, available to pay interest, income tax expense is inversely correlated to interest expense because tax expense goes down as deductible interest expense goes up, and depreciation and amortization are non-cash charges. In addition, we believe EBITDA is frequently used by securities analysts, investors and other interested parties in the evaluation of REITs. Because EBITDA is calculated before recurring cash charges including interest expense and income taxes, and is not adjusted for capital expenditures or other recurring cash requirements of our business, its utility as a measure of our performance is limited. Accordingly, EBITDA should be considered only as supplement to net income (computed in accordance with GAAP) as a measure of our financial performance. Other equity REITs may calculate EBITDA differently than we do; accordingly, our EBITDA may not comparable to such other REITs’ EBITDA.
