                     service revenue.  Management
                     believes that Non-GAAP gross
                     profit and Non-GAAP gross profit
                     margin are relevant metrics to
                     provide investors, as they are
                     metrics that management uses to
                     measure the margin available to
                     the company after network service
                     costs, in essence a measure of the
                     efficiency of the Company's
                     network.

    (5)              Excludes equity-based compensation

Schedules of Non-GAAP Measures

EBITDA and EBITDA, as adjusted

EBITDA represents net cash flows from operating activities plus changes in operating assets and liabilities, cash interest expense and cash income tax expense. Management believes the most directly comparable measure to EBITDA calculated in accordance with generally accepted accounting principles in the United States, or GAAP, is cash flows provided by operating activities. The Company also believes that EBITDA is a measure frequently used by securities analysts, investors, and other interested parties in their evaluation of issuers. EBITDA, as adjusted, represents EBITDA plus net gains (losses) on asset related transactions.

The Company believes that EBITDA, and EBITDA, as adjusted, are useful measures of its ability to service debt, fund capital expenditures and expand its business. EBITDA, and EBITDA, as adjusted are an integral part of the internal reporting and planning system used by management as a supplement to GAAP financial information. EBITDA, and EBITDA, as adjusted are not recognized terms under GAAP and accordingly, should not be viewed in isolation or as a substitute for the analysis of results as reported under GAAP, but rather as a supplemental measure to GAAP. For example, these metrics are not intended to reflect the Company's free cash flow, as it does not consider certain current or future cash requirements, such as capital expenditures, contractual commitments, and changes in working capital needs, interest expenses and debt service requirements. The Company's calculations of these metrics may also differ from the calculations performed by its competitors and other companies and as such, its utility as a comparative measure is limited.

EBITDA, and EBITDA, as adjusted, are reconciled to cash flows provided by operating activities in the table below.

                     and amortization and equity based
                     compensation included in network
                     operations expense.  GAAP gross
                     margin is defined as GAAP gross
                     profit divided by total service
                     revenue.

    (2)              Non-GAAP gross profit represents

                     expense). Non-GAAP gross margin
                     is defined as non-GAAP gross
                     profit divided by total service
                     revenue.  Management believes that
                     non-GAAP gross profit and non-
                     GAAP gross margin are relevant
                     metrics to provide to investors,
                     as they are metrics that
                     management uses to measure the
                     margin and amount available to the
                     Company after network service
                     costs, in essence these are
                     measures of the efficiency of the
                     Company's network.

Except for historical information and discussion contained herein, statements contained in this release constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements include, but are not limited to statements identified by words such as "believes," "expects," "anticipates," "estimates," "intends," "plans," "targets," "projects" and similar expressions. The statements in this release are based upon the current beliefs and expectations of Cogent's management and are subject to significant risks and uncertainties. Actual results may differ from those set forth in the forward-looking statements. Numerous factors could cause or contribute to such differences, including future economic instability in the global economy or a contraction of the capital markets which could affect spending on Internet services and our ability to engage in financing activities; the impact of changing foreign exchange rates (in particular the Euro to USD and Canadian dollar to USD exchange rates) on the translation of our non-USD denominated revenues, expenses, assets and liabilities; legal and operational difficulties in new markets; the imposition of a requirement that we contribute to the US Universal Service Fund on the basis of our Internet revenue; changes in government policy and/or regulation, including net neutrality rules by the United States Federal Communications Commission and in the area of data protection; increasing competition leading to lower prices for our services; our ability to attract new customers and to increase and maintain the volume of traffic on our network; the ability to maintain our Internet peering arrangements on favorable terms; our reliance on an equipment vendor, Cisco Systems Inc., and the potential for hardware or software problems associated with such equipment; the dependence of our network on the quality and dependability of third-party fiber providers; our ability to retain certain customers that comprise a significant portion of our revenue base; the management of network failures and/or disruptions; and outcomes in litigation as well as other risks discussed from time to time in our filings with the Securities and Exchange Commission, including, without limitation, our report on Form 10-Q for the quarter ended September 30, 2017 to be filed with the Securities and Exchange Commission. Cogent undertakes no duty to update any forward-looking statement or any information contained in this press release or in other public disclosures at any time.
