Non-GAAP Financial Measures

The Company provides financial measures that are not defined under generally accepted accounting principles in the United States, or GAAP,

including Adjusted EBITDA, Adjusted EBITDA Margin, unlevered free cash flow, adjusted unlevered free cash flow, levered free cash flow, adjusted

funds from operations, and net adjusted funds from operations.

Adjusted EBITDA is defined as earnings/(loss) from continuing operations before interest, income taxes, depreciation, and amortization (“EBITDA”)

adjusted to exclude acquisition or disposal-related transaction costs, losses on extinguishment of debt, stock-based compensation, unrealized

foreign currency gains/ (losses) on intercompany loans, and non-cash income/(loss) on equity and cost method investments. Adjusted EBITDA

Margin is defined as Adjusted EBITDA divided by revenue. Unlevered free cash flow is defined as Adjusted EBITDA minus purchases of property

and equipment, net of stimulus grants. Adjusted unlevered free cash flow is defined as Adjusted EBITDA minus purchases of property and

equipment, net of stimulus grants, plus additions to deferred revenue, less non-cash monthly amortized revenue. Levered free cash flow is defined

as operating cash flow minus purchases of property and equipment, net of stimulus grants. Adjusted funds from operations (“AFFO”) is defined as

earnings/(loss) from continuing operations before depreciation and amortization, unrealized foreign currency gains/(losses) on intercompany loans,

stock-based compensation, acquisition or disposal-related transaction costs, losses on extinguishment of debt, non-cash income/(loss) on equity

and cost investments, non-cash monthly amortized revenue, less cash payments related to maintenance capital expenditures. Net AFFO is defined

as AFFO plus upfront customer payments from less than twelve month payback on net new sales less cash payments related to capital

expenditures for (i) less than twelve month payback on net new sales and (ii) network capacity. These measures are not measurements of our

financial performance under GAAP and should not be considered in isolation or as alternatives to net income, net cash flows provided by operating

activities, total net cash flows or any other performance measures derived in accordance with GAAP or as alternatives to net cash flows from

operating activities or total net cash flows as measures of our liquidity.

We use Adjusted EBITDA to evaluate our operating performance and liquidity, and we use levered free cash flow as a measure to evaluate cash

generated through normal operating activities. In addition to Adjusted EBITDA, management uses unlevered free cash flow, which measures the

ability of Adjusted EBITDA to cover capital expenditures. Adjusted EBITDA is a performance rather than cash flow measure. Correlating our capital

expenditures to our Adjusted EBITDA does not imply that we will be able to fund such capital expenditures solely with cash from operations. In

addition to these measures, we use levered free cash flow as a measure to evaluate cash generated through normal operating activities. These

metrics are among the primary measures used by management for planning and forecasting future periods. We believe the presentation of

Adjusted EBITDA is relevant and useful for investors because it allows investors to view results in a manner similar to the method used by

management and make it easier to compare our results with the results of other companies that have different financing and capital structures. We

believe that the presentation of levered free cash flow is relevant and useful to investors because it provides a measure of cash available to pay the

principal on our debt and pursue acquisitions of businesses or other strategic investments or uses of capital. We believe the presentation of AFFO

and Net AFFO is useful to investors by providing measures presented by certain datacenter and cellular tower REITs (and some non-REITs) with

which we are sometimes compared.

Non-GAAP Financial Measures

We also monitor Adjusted EBITDA because our subsidiaries have debt covenants that restrict their borrowing capacity that are based on a leverage

ratio, which utilizes a modified EBITDA, as defined in our credit agreement and the indentures governing our notes. The modified EBITDA is

consistent with our definition of Adjusted EBITDA; however, it includes the pro forma Adjusted EBITDA of and expected cost synergies from the

companies acquired by us during the quarter for which the debt compliance certification is due. Adjusted EBITDA results, along with the

quantitative and qualitative information, are also utilized by management and our Compensation Committee, as an input for determining incentive

payments to employees.

Adjusted EBITDA has limitations as an analytical tool and should not be considered in isolation from, or as a substitute for, analysis of our results of

operations and operating cash flows as reported under GAAP. For example, Adjusted EBITDA:

-does not reflect capital expenditures, or future requirements for capital and major maintenance expenditures or contractual

commitments;

- does not reflect changes in, or cash requirements for, our working capital needs;

- does not reflect the interest expense, or the cash requirements necessary to service the interest payments, on our debt; and

- does not reflect cash required to pay income taxes.

Unlevered free cash flow and adjusted unlevered free cash flow have limitations as analytical tools and should not be considered in isolation from,

or as a substitute for, analysis of our results as reported under GAAP. For example, unlevered free cash flow:

- does not reflect changes in, or cash requirements for, our working capital needs;

- does not reflect the interest expense, or the cash requirements necessary to service the interest payments, on our debt; and

- does not reflect cash required to pay income taxes.

Levered free cash flow, AFFO, and Net AFFO have limitations as an analytical tool and should not be considered in isolation from, or as a

substitute for, analysis of our results as reported under GAAP. For example, levered free cash flow, AFFO, and Net AFFO:

- does not reflect principal payments on debt;

- does not reflect principal payments on capital lease obligations;

- does not reflect dividend payments, if any; and

- does not reflect the cost of acquisitions.

Non-GAAP Financial Measures

Our computation of Adjusted EBITDA, unlevered free cash flow, adjusted unlevered free cash flow, levered free cash flow, AFFO,

and Net AFFO may not be comparable to other similarly titled measures computed by other companies because all companies do not

calculate these measures in the same fashion.

Because we have acquired numerous entities since our inception and incurred transaction costs in connection with each acquisition,

borrowed money in order to finance our operations and acquisitions, and used capital and intangible assets in our business, and

because the payment of income taxes is necessary if we generate taxable income after the utilization of our net operating loss

carryforwards, any measure that excludes these items has material limitations. As a result of these limitations, these measures

should not be considered as a measure of discretionary cash available to us to invest in the growth of our business or as a measure

of our liquidity. See “Reconciliation of Non-GAAP Financial Measures” for a quantitative reconciliation of Adjusted EBITDA, AFFO,

and Net AFFO to net income/(loss) and for a quantitative reconciliation of unlevered free cash flow, adjusted unlevered free cash flow

and levered free cash flow to net cash flows provided by operating activities.

Annualized revenue and annualized Adjusted EBITDA are derived by multiplying the total revenue and Adjusted EBITDA,

respectively, for the most recent quarterly period by four. Our computations of annualized revenue and annualized Adjusted EBITDA

may not be representative of our actual annual results.

Measures referred to as being calculated on a constant currency basis are intended to present the relevant information assuming a

constant exchange rate between the two periods being compared. Such metrics are calculated by applying the currency exchange

rates used in the preparation of the prior period financial results to the subsequent period results.

Tables reconciling such non-GAAP measures are included in the Historical Financial Data & Reconciliations section of this

presentation. A glossary of terms used throughout is available under the investor section of the Company’s website at

http://www.zayo.com/investors.
