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 technology related real estate; 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.

Corporate Information

Corporate Profile

Digital Realty Trust is firmly positioned at the crossroads of real estate and technology and focuses solely on the ownership of technology real estate:

• We own and operate properties that are critical to the operations of our tenants;

• As of December 31, 2005, our portfolio is primarily located in 20 major metropolitan areas including 17 in the United States and three in Europe;

• We concentrate on areas within the technology industry that we believe have growth potential. As such, we emphasize properties that provide the infrastructure for sectors such as corporate data centers, disaster recovery and business continuity, electronic commerce and the security of stored or transmitted electronic data.

As of December 31, 2005, our 43 property portfolio, totaling 8.1 million square feet excluding approximately 1.1 million square feet of space held for development, consists mainly of highly improved properties containing specialized facilities that play a critical role in our tenants' operations and in the delivery of services to their customers. We maintain a significant focus on Internet gateway and data center properties that are located at the junction of major high-speed data networks that deliver Internet, data, voice, video, wireless and satellite services.

Our tenant base includes media, communications and technology-based businesses, Internet enterprises and Fortune 1000 companies. Our tenants' operations typically require specially designed and engineered facilities that maintain sophisticated security systems, robust and redundant power services, backup power systems, redundant air conditioning systems and advanced fire suppression systems.

(1) Assuming 100% conversion of the limited partnership units in the operating partnership into shares of our common stock.

(2) EBITDA is calculated as earnings before interest, taxes and depreciation. Adjusted EBITDA is EBITDA adjusted for preferred dividends and minority interests. Debt service coverage ratio is calculated as adjusted EBITDA divided by cash interest expense. For a definition of cash interest expense, see page 15. For a discussion of Adjusted EBITDA and EBITDA, see page 25. For a quantitative reconciliation of the differences between EBITDA and Adjusted EBITDA and net income, see page 13.

(3) Calculated as Adjusted EBITDA divided by fixed charges. For a definition of fixed charges, see page 15.

(4) The net loss per common share - basic and diluted is for the period from November 3, 2004 to December 31, 2004. This may not be comparable future net income (loss) per common share since it includes the effect of various IPO-related charges.

(5) For a definition and discussion of FFO and AFFO, see page 25. For a quantitative reconciliation of the differences between FFO and net income, see page 11. For a quantitative reconciliation of the differences between FFO and AFFO, see page 12.

(6) Calculated as dividend declared per common share divided by FFO or AFFO per common share - diluted.

(7) Redevelopment space requires significant capital investment in order to develop datacenter facilities that are ready for use. Most often this is shell space. However, in certain circumstances this may include partially built datacenter space that was not completed by previous ownership and requires a large capital investment in order to build out the space.

(8) Occupancy at end of quarter excludes space held for redevelopment. We completed a review of space held for development in the quarter ended September 30, 2005 and have not restated any occupancy statistics for March 31, 2005 and earlier periods. This will cause occupancy statistics for March 31, 2005 and earlier periods to not be comparable to occupancy statistics for later periods.

Note: The Predecessor is not a legal entity; rather it is a combination of certain of the real estate subsidiaries of Global Innovation Partners, LLC, a Delaware limited liability company (GI Partners) along with an allocation of certain assets, liabilities, revenues and expenses of GI Partners related to the real estate held by such subsidiaries. The financial statements presented are the consolidated financial statements of the Company. The financial statements presented for periods prior to November 3, 2004 are the combined financial statements of the Predecessor.

(1) In the final quarter of 2005 we renamed our properties based on the address of each building. Please see page 24 for a list of the former names used in previous supplemental information presentations.

(2) Annualized rent represents the monthly contractual rent under existing leases as of December 31, 2005 multiplied by 12. 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.

(3) The December 31, 2005 occupancies excludes the redevelopment space in the column above. We completed a review of space held for development in the quarter ended September 30, 2005 and have not restated any occupancy statistics for March 31, 2005 and earlier periods. This will cause occupancy statistics for March 31, 2005 to not be comparable to occupancy statistics for later periods.

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 value 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 and Adjusted EBITDA:

We believe that earnings before interest, income taxes, depreciation and amortization, or EBITDA and Adjusted EBITDA (as defined below), are useful supplemental performance measures because they allow investors to view our performance without the impact or noncash depreciation and amortization or the cost of debt and with respect to Adjusted EBITDA preferred dividends and minority interests. Adjusted EBITDA is EBITDA excluding minority interests and preferred stock dividends. In addition, we believe EBITDA and adjusted EBITDA are frequently used by securities analysts, investors and other interested parties in the evaluation of REITs. Because EBITDA and adjusted EBITDA are calculated before recurring cash charges including interest expense and income taxes, and are not adjusted for capital expenditures or other recurring cash requirements of our business, their utility as a measure of our performance is limited. Accordingly, EBITDA and Adjusted EBITDA should be considered only as supplements to net income (computed in accordance with GAAP) as a measure of our financial performance. Other equity REITs may calculate EBITDA and Adjusted EBITDA differently than we do; accordingly, our EBITDA and Adjusted EBITDA may not comparable to such other REITs’ EBITDA and Adjusted EBITDA.
