FORWARD-LOOKING STATEMENTS Certain statements in this presentation contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include statements regarding industry trends, our future financial position and performance, business strategy, revenues and expenses in future periods, projected levels of growth and other matters that do not relate strictly to historical facts. These statements are often identified by words such as “may,” “will,” “seeks,” “anticipates,” “believes,” “estimates,” “expects,” “projects,” “forecasts,” “plans,” “intends,” “continue,” “could” or “should,” that an “opportunity” exists, that we are “positioned” for a particular result, statements regarding our vision or similar expressions or variations. These statements are based on the beliefs and expectations of our management team based on information available at the time such statements are made. Such forward-looking statements are not guarantees of future performance and are subject to risks and uncertainties that could cause actual results to differ materially from those contemplated by such forward-looking statements. Therefore, actual future results and trends may differ materially from what is forecast in such forward-looking statements due to a variety of factors, including, without limitation: our ability to drive growth while reducing costs; our ability to maintain current customers and obtain new ones, whether in a cost-effective manner or at all; the robustness of the IT infrastructure services market; our ability to achieve or sustain profitability; our ability to expand margins and drive higher returns on investment; our ability to sell into new and existing data center space; the actual performance of our IT infrastructure services and our ability to improve operations; our ability to correctly forecast capital needs, demand and space utilization; our ability to respond successfully to technological change and the resulting competition; the geographic concentration of our data centers in certain markets and any adverse developments in local economic conditions or the demand for data center space in these markets; our ability to identify any suitable strategic transactions; our ability to realize anticipated revenue, growth, synergies and cost savings from the acquisition of SingleHop LLC (“SingleHop”); our ability to successfully integrate SingleHop’s sales, operations, technology, and products generally; the availability of services from Internet network service providers or network service providers providing network access loops and local loops on favorable terms, or at all; the failure of third party suppliers to deliver their products and services on favorable terms, or at all; failures in our network operations centers, data centers, network access points or computer systems; our ability to provide or improve Internet infrastructure services to our customers; our ability to protect our intellectual property; our substantial amount of indebtedness, our ability to raise additional capital when needed, on attractive terms, or at all, and our ability to service existing debt or maintain compliance with financial and other covenants contained in our credit agreement; our compliance with and changes in complex laws and regulations in the U.S. and internationally; our ability to attract and retain qualified management and other personnel; and volatility in the trading price of INAP common stock. These risks and other important factors discussed under the caption “Risk Factors” in our most recent Annual Report on Form 10-K filed with the SEC and our other reports filed with the SEC could cause actual results to differ materially from those expressed or implied by forward-looking statements made by INAP or on our behalf. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements as a prediction of actual results. All forward-looking statements attributable to INAP or persons acting on our behalf are expressly qualified in their entirety by the foregoing forward-looking statements. All such statements speak only as of the date made, and INAP undertakes no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise. © 2019 Internap Corporation (INAP) 2

NON-GAAP MEASURES In addition to results presented in accordance with GAAP, this presentation includes non-GAAP financial measures. INAP believes these non-GAAP financial measures provide additional information that is useful to investors in helping to understand our underlying performance and trends. Non-GAAP financial measures have inherent limitations, which are not required to be uniformly applied. Readers should be aware of these limitations and should be cautious with respect to the use of such measures. To compensate for these limitations, we use non-GAAP financial measures as comparative tools, together with GAAP financial measures, to assist in the evaluation of our operating performance or financial condition. Our method of calculating these non-GAAP financial measures may differ from methods used by other companies. These non-GAAP financial measures should not be considered in isolation or as a substitute for those financial measures prepared in accordance with GAAP.We have provided in this presentation reconciliations of the non-GAAP financial measures included in this presentation to the most directly comparable GAAP financial measures. © 2019 Internap Corporation (INAP) 3
