DIGITAL REALTY REPORTS FOURTH QUARTER

AND FULL-YEAR 2013 RESULTS

San Francisco, Calif. (February 24, 2014) – Digital Realty Trust, Inc. (NYSE: DLR), a leading global provider of data center solutions, announced today financial results for the fourth quarter and full-year 2013. All per share results are presented on a fully-diluted share and unit basis.

Highlights

“Digital Realty closed the year on a very positive note, with record leasing results for the fourth quarter and full-year 2013 driven by strong sales execution and large customer requirements to deploy cloud infrastructure and applications. We are encouraged by the broader range of customers we are attracting as a result of our mid-market initiative as well as strong customer demand for our colocation offerings,” said Michael F. Foust, Digital Realty’s Chief Executive Officer. “Fourth quarter financial results were ahead of plan due to a combination of lower-than-expected financing costs from the delayed execution of anticipated long-term debt and preferred equity issuances, lower bonus accruals, and operating expense savings from efficient property-level technical operations. Our strong fourth quarter leasing and financial results set the stage for positive forward momentum in 2014.”

Funds From Operations

Funds from operations (“FFO”) on a diluted basis was $174.4 million in the fourth quarter of 2013, or $1.26 per share, compared to $1.10 per share in the third quarter of 2013 and $1.16 per share in the fourth quarter of 2012. Excluding certain items that do not represent core expenses or revenue streams, fourth quarter 2013 core FFO was $1.26 per share compared to $1.16 per share in the third quarter of 2013 and $1.19 per share in the fourth quarter of 2012. FFO per share for the full-year 2013 was $4.74 compared to $4.44 in 2012. Core FFO per share for the full-year 2013 was $4.78 compared to $4.46 in 2012.

Net income for the fourth quarter of 2013 was $55.7 million, and net income available to common stockholders in the fourth quarter of 2013 was $43.0 million, or $0.33 per share, compared to $1.06 per share in the third quarter of 2013 and $0.36 per share in the fourth quarter of 2012. For the year ended December 31, 2013, net income was $320.4 million, and net income available to common stockholders for the year ended December 31, 2013 was $271.6 million, or $2.12 per share, compared to $1.48 per share in 2012.

Funds From Operations

Digital Realty 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, impairment charges, 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 and after adjustments for unconsolidated partnerships and joint ventures, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. Digital Realty 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 capitalized leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effect and could materially impact our financial condition and 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 computed in accordance with GAAP as a measure of our performance.

Core Funds from Operations

We present core funds from operations, or CFFO, as a supplemental operating measure because, in excluding certain items that do not reflect core revenue or expense streams, it provides a performance measure that, when compared year over year, captures trends in our core business operating performance. We calculate CFFO by adding to or subtracting from FFO (i) termination fees and other non-core revenues, (ii) significant transaction expenses, (iii) loss from early extinguishment of debt, (iv) costs on redemption of preferred stock, (v) significant property tax adjustments, net and (vi) other non-core expense adjustments. Because certain of these adjustments have a real economic impact on our financial condition and results from operations, the utility of CFFO as a measure of our performance is limited. Other REITs may not calculate CFFO in a consistent manner. Accordingly, our CFFO may not be comparable to other REITs’ CFFO. CFFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.

EBITDA and Adjusted EBITDA

We believe that earnings before interest expense, 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 of non-cash depreciation and amortization or the cost of debt and, with respect to Adjusted EBITDA, straight-line rent expense adjustment attributable to prior periods, gain on contribution of properties to unconsolidated joint venture, noncontrolling interests, and preferred stock dividends. Adjusted EBITDA is EBITDA excluding straight-line rent expense adjustment attributable to prior periods, gain on contribution of properties to unconsolidated joint venture, noncontrolling 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, exclude capitalized costs, such as leasing commissions, 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. Other REITs may calculate EBITDA and Adjusted EBITDA differently than we do; accordingly, our EBITDA and Adjusted EBITDA may not be comparable to such other REITs’ EBITDA and Adjusted EBITDA. 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.

Additional Definitions

Net debt-to-Adjusted EBITDA ratio is calculated using total debt at balance sheet carrying value less unrestricted cash and cash equivalents divided by the product of Adjusted EBITDA multiplied by four.

Debt-plus-preferred-to-total-enterprise-value is mortgage debt and other loans plus preferred stock divided by mortgage debt and other loans plus the liquidation value of preferred stock and the market value of outstanding Digital Realty Trust, Inc. common stock and Digital Realty Trust, L.P. units, assuming the redemption of Digital Realty Trust, L.P. units for shares of Digital Realty Trust, Inc. common stock.

Fixed charge coverage ratio is Adjusted EBITDA divided by the sum of GAAP interest expense, scheduled debt principal payments and preferred dividends. For the quarter ended December 31, 2013, GAAP interest expense was $46.0 million and scheduled debt principal payments and preferred dividends was $14.8 million.
