Statement Regarding Forward-Looking Statements

This supplemental package contains forward-looking statements within the meaning of the federal securities laws, including information related to trends, leasing expectations, weighted average lease terms, the exercise of lease extensions, lease expirations, debt maturities, annualized rent at expiration of leases, the effect new leases and increases in rental rates will have on our rental revenue, our credit ratings, construction and development activity, projected construction costs and other forward-looking financial data. 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:

• the impact of the recent deterioration in global economic, credit and market conditions, including the downgrade of the U.S. government’s credit rating;

• current local economic conditions in our geographic markets;

• decreases in information technology spending, including as a result of economic slowdowns or recession;

• adverse economic or real estate developments in our industry or the industry sectors that we sell to (including risks relating to decreasing real estate valuations and impairment charges);

• our dependence upon significant tenants;

• bankruptcy or insolvency of a major tenant or a significant number of smaller tenants;

• defaults on or non-renewal of leases by tenants;

• our failure to obtain necessary debt and equity financing;

• increased interest rates and operating costs;

• risks associated with using debt to fund our business activities, including re-financing and interest rate risks, our failure to repay debt when due, adverse changes in our credit ratings or our breach of covenants or other terms contained in our loan facilities and agreements;

• financial market fluctuations;

• changes in foreign currency exchange rates;

• our inability to manage our growth effectively;

• difficulty acquiring or operating properties in foreign jurisdictions;

• our failure to successfully integrate and operate acquired or developed properties or businesses;

• the suitability of our properties and data center infrastructure, delays or disruptions in connectivity, failure of our physical infrastructure or services or availability of power;

• risks related to joint venture investments, including as a result of our lack of control of such investments;

• delays or unexpected costs in development of properties;

• decreased rental rates or increased vacancy rates;

• increased competition or available supply of data center space;

• our inability to successfully develop and lease new properties and space held for development;

• difficulties in identifying properties to acquire and completing acquisitions;

• our inability to acquire off-market properties;

• our inability to comply with the rules and regulations applicable to reporting companies;

• our failure to maintain our status as a REIT;

• possible adverse changes to tax laws;

• restrictions on our ability to engage in certain business activities;

• environmental uncertainties and risks related to natural disasters;

• losses in excess of our insurance coverage;

• changes in foreign laws and regulations, including those related to taxation and real estate ownership and operation; and

• changes in local, state and federal regulatory requirements, including 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, 2012, 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) The market value of common equity is based on the closing stock price at the end of the quarter and assumes 100% redemption of the limited partnership units in our operating partnership, including common units and vested and unvested long-term incentive units (including vested class C units), for shares of our common stock. Excludes shares issuable with respect to stock options that have been granted but have not yet been exercised, and also excludes all shares potentially issuable upon exchange of our 5.50% exchangeable senior debentures due 2029 or upon conversion of our series E and series F cumulative redeemable preferred stock upon certain change of control transactions.

(2) EBITDA is calculated as earnings before interest, taxes, depreciation and amortization. For a discussion of EBITDA, see page 31. For a reconciliation of net income available to common stockholders to EBITDA, see page 11.

(3) Adjusted EBITDA is EBITDA adjusted for preferred dividends and non-controlling interests. For a discussion of Adjusted EBITDA, see page 31. For a reconciliation of net income available to common stockholders to Adjusted EBITDA, see page 11.

(4) Cash interest expense is interest expense per our statement of operations less amortization of debt discount and deferred financing fees and includes interest that we capitalized. For a reconciliation of GAAP interest expense to cash interest expense, see page 11.

(5) Fixed charges consist of cash interest expense, scheduled debt principal payments and preferred dividends.

(6) Debt service coverage ratio is Adjusted EBITDA divided by cash interest expense.

(7) Fixed charge coverage ratio is Adjusted EBITDA divided by fixed charges.

(8) For a definition and discussion of FFO, see page 31. For a reconciliation of net income available to common stockholders to FFO, see page 10.

(9) All periods presented include internal leasing commissions, the amounts of which have historically been included in capitalized leasing commissions and were previously excluded from recurring capital expenditures. For a definition and discussion of AFFO, see page 31. For a reconciliation of FFO to AFFO, see page 10.

(10) Diluted FFO payout ratio is dividends declared per common share and unit divided by diluted FFO per share and unit.

(11) Diluted AFFO payout ratio is dividends declared per common share and unit divided by diluted AFFO per share and unit.

(12) Development space requires significant capital investment in order to develop data center 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.

(13) Occupancy and same store occupancy exclude space held for development. For some of our properties, we calculate occupancy based on factors in addition to contractually leased square feet, including available power, required support space and common area.

(14) Weighted average remaining lease term excludes renewal options and is weighted by net rentable square feet.

(15) Same store properties were acquired before December 31, 2011.

(a) Cash interest expense is interest expense less amortization of debt discount and deferred financing fees and includes interest that we capitalized. We consider cash interest expense to be a useful measure of interest as it excludes non-cash based interest expense.

(b) Fixed charges consist of cash interest expense, scheduled debt principal payments and preferred dividends.

(c) Adjusted EBITDA divided by GAAP interest expense.

(d) Adjusted EBITDA divided by cash interest expense.

(e) Adjusted EBITDA divided by the sum of GAAP interest expense, scheduled debt principal payments and preferred dividends.

(f) Adjusted EBITDA divided by fixed charges.

(g) Mortgage debt and other loans divided by mortgage debt and other loans plus the liquidation value of preferred stock and the market value of outstanding common stock and operating partnership units, assuming the redemption of operating partnership units for shares of our common stock.

(h) Same as (e), except numerator includes preferred stock.

(i) Calculated as net income, adding back interest expense and divided by GAAP interest expense.

(j) Calculated as total debt at balance sheet carrying value (see page 7) less unrestricted cash and cash equivalents divided by the product of Adjusted EBITDA multiplied by four.

(1) Number of leases represents the leased-unit count; a lease could include multiple units.

(2) For some of our properties, we calculate square footage based on factors in addition to contractually leased square feet, including available power, required support space and common area. We estimate the total net rentable square feet available for lease based on a number of factors in addition to contractually leased square feet, including available power, required support space and common area.

(3) Annualized rent represents the monthly contractual base rent (defined as cash base rent before abatements) under existing leases as of March 31, 2013 multiplied by 12.

(4) Includes leases, licenses and similar agreements that upon expiration have been automatically renewed on a month-to-month basis.

(1) Recurring capital expenditures represent non-incremental building improvements required to maintain current revenues along with leasing commissions. Recurring capital expenditures do not include acquisition capital that was taken into consideration when underwriting the purchase of a building or which are incurred to bring a building up to “operating standard”.

(2) Non-recurring capital expenditures are primarily for development of space and land not including acquisition costs. In addition, these expenditures include certain infrequent expenditures for capitalized replacement, repair, maintenance, or other projects which enhance the existing operating portfolio (e.g., electrical, mechanical and building upgrades).

(3) For some of our properties, we calculate square footage based on factors in addition to contractually leased square feet, including available power, required support space and common area.

Management Statements on Non-GAAP Supplemental Measures

Funds from Operations (FFO):

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, 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. 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 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.

Adjusted Funds from Operations (AFFO):

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, including on a per share and unit basis. We calculate AFFO by adding to or subtracting from FFO (i) non-real estate depreciation, (ii) amortization of deferred financing costs, (iii) amortization of debt discount, (iv) non-cash compensation, (v) loss from early extinguishment of debt, (vi) straight line rents, (vii) fair value of lease revenue amortization, (viii) change in fair value of contingent consideration, (ix) capitalized leasing payroll, (x) recurring tenant improvements, (xi) capitalized leasing commissions and (xii) costs of redeeming our preferred stock. Other REITs may not calculate AFFO in a consistent manner. Accordingly, our AFFO may not be comparable to other REITs’ AFFO. AFFO 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, preferred dividends and noncontrolling interests. Adjusted EBITDA is EBITDA excluding noncontrolling interests, preferred stock dividends and costs of redeeming our preferred stock. 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.

Net Operating Income (NOI):

Net operating income, or NOI, represents rental revenue and tenant reimbursement revenue less rental property operating and maintenance expenses, property taxes and insurance expenses (as reflected in the statement of operations). NOI is commonly used by stockholders, company management and industry analysts as a measurement of operating performance of the company’s rental portfolio. However, because NOI 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 results from operations, the utility of NOI as a measure of our performance is limited. Other REITs may not calculate NOI in the same manner we do and, accordingly, our NOI may not be comparable to such other REITs’ NOI. Accordingly, NOI should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.
