Definitions of Non-GAAP Financial Measures

The information included in this presentation contains certain non-GAAP financial measures that management believes are helpful in understanding our business, as further described below. Our definition and calculation of non-

GAAP financial measures may differ from those of other REITs, and, therefore, may not be comparable. The non-GAAP financial measures should not be considered an alternative to net income or any other GAAP measurement

of performance and should not be considered an alternative to cash flows from operating, investing or financing activities as a measure of liquidity.

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, excluding a gain from a pre-existing relationship, 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.

CORE FUNDS FROM OPERATATIONS (Core FFO)

We present core funds from operations, or core FFO, 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 core FFO by adding to or subtracting from FFO (i) termination fees and other non-core revenues, (ii) transaction expenses, (iii)

loss from early extinguishment of debt, (iv) change in fair value of contingent consideration, (v) severance-related accrual, equity acceleration, and legal expenses, (vi) bridge facility fees and (vii) 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 core FFO as a measure of our performance is limited. Other REITs may not

calculate core FFO in a consistent manner. Accordingly, our core FFO may not be comparable to other REITs' core FFO. Core FFO should be considered only as a supplement to net income computed in accordance with GAAP as a

measure of our performance.

CONSTANT CURRENCY CORE FUNDS FROM OPERATIONS

We calculate constant-currency core funds from operations by adjusting the core funds from operations for foreign currency translations.

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 core FFO (i) non-real estate depreciation, (ii) amortization of deferred financing costs, (iii) amortization of debt discount/premium, (iv) non-cash stock-

based compensation expense, (v) non-cash stock-based compensation expense, (vi) straight-line rent revenue, (vii) straight-line rent expense, (viii) above- and below-market rent amortization, (ix) non-cash tax expense, (x)

capitalized leasing compensation, (xi) recurring capital expenditures and (xii) capitalized internal leasing commissions. 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.

Page 73: Company Overview – May 2016 - Updated

Definitions of Non-GAAP Financial Measures (cont.)

EBITDA AND ADJUSTED EBITDA:

We believe that earnings before interest, loss from early extinguishment of debt, income taxes and 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, change in fair value of contingent consideration, severance related accrual, equity acceleration, and legal expenses, transaction expenses, (gain) loss on sale of property, (gain) loss

on settlement of pre-existing relationship with Telx, other non-core expense adjustments, non-controlling interests, and preferred stock dividends. Adjusted EBITDA is EBITDA excluding change in fair

value of contingent consideration, severance related accrual, equity acceleration, and legal expenses, transaction expenses, gain (loss) on sale of property, gain on settlement of pre-existing

relationship with Telx, other non-core expense adjustments, non-controlling 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.

NET OPERATING INCOME (NOI) AND CASH NOI

Net Operating Income (NOI) and Cash NOI: Net operating income, or NOI, represents rental revenue, interconnection revenue and tenant reimbursement revenue less utilities, rental property

operating expenses, repair 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. Cash NOI is NOI less straight-line rents and above and below market rent

amortization. Cash NOI is commonly used by stockholders, company management and industry analysts as a measure of property operating performance on a cash basis. However, because NOI and

cash NOI exclude depreciation and amortization and capture 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 and cash NOI as measures of our performance is limited. Other REITs may not calculate NOI and cash NOI in the same manner we do and, accordingly, our NOI and cash NOI may not be

comparable to such other REITs’ NOI and cash NOI. Accordingly, NOI and cash NOI should be considered only as supplements to net income computed in accordance with GAAP as measures of our

performance.

SAME-CAPITAL CASH NOI

Same-capital Cash NOI is Cash NOI (as defined above) calculated for “Same-capital” properties. “Same-capital” properties are defined as properties owned as of December 31, 2013 with less than 5%

of total rentable square feet under development and excludes properties that were undergoing, or were expected to undergo, development activities in 2014-2015, properties classified as held for

sale, and properties sold or contributed to joint ventures for all periods presented.

Core EBITDA is a non-GAAP financial metric that Telx uses as a supplemental measure of its operating performance that adjusts net loss to eliminate the impact of certain items that it does not consider

indicative of its core operating performance. We believe that Core EBITDA is a useful supplemental performance measure because it allows investors to view Telx’s performance without the impact of non-

cash depreciation and amortization, the cost of debt, deferred rent expenses, stock-based compensation expenses, sponsor management fees and transaction costs. Other companies may calculate Core

EBITDA or similar metrics differently; accordingly, the Core EBITDA presented herein may not be comparable to other companies’ Core EBITDA or similar metrics.
