Legal disclaimer Forward-Looking Statements Certain statements in this presentation and in any accompanying oral remarks made in connection with this presentation are “forward-looking statements” within the meaning of securities laws. You should not place undue reliance on these statements. Forward-looking statements include information concerning our liquidity and our possible or assumed future results of operations, including descriptions of our business strategies, as well as cost savings and other benefits we expect to achieve (and the timing thereof) as discussed herein. These statements often include words such as “believe,” “expect,” “anticipate,” “intend,” “plan,” “estimate,” “seek,” “will,” “may” or similar expressions. These statements are based on certain assumptions that we have made in light of our experience in the industry as well as our perceptions of historical trends, current conditions, expected future developments and other factors we believe are appropriate in these circumstances. You should understand that these statements are not guarantees of performance or results. They involve risks, uncertainties and assumptions which are discussed in detail in the Company’s most recent Form 10-K Annual Report for the year ended December 31, 2015 filed with the Securities and Exchange Commission (the “SEC”) on March 17, 2016 and our Form 10-Q Quarterly Reports subsequently filed with the SEC which should be read in conjunction with this presentation. Furthermore, we have not yet filed the Company’s Form 10-K Annual Report for the year ended December 31, 2016 with the SEC. When the Company ultimately files its Form 10-K Annual Report with the SEC, actual results and financial information related to the quarter and year ended December 31, 2016 could differ materially from those reflected in the forward-looking statements contained herein as a result of a variety of factors, many of which are beyond the Company’s control. The Company assumes no responsibility to update or revise any forward-looking statements as a result of new information or future developments. Third Party Information This presentation has been prepared by the Company and includes information from other sources believed by management to be reliable. No representation or warranty, express or implied, is made as to the accuracy or completeness of any of the information set forth herein. This presentation may contain summaries of the terms of certain documents and agreements, but reference is made to the actual documents and agreements for the complete information contained therein. The information contained herein is as of the date hereof and is subject to change, completion or amendment without notice. Non-GAAP Financial Measures We have included certain non-GAAP financial measures in this presentation, including Pro Forma Total Revenue, Adjusted EBITDA, Pro Forma Adjusted EBITDA, Pro Forma Capital Expenditures, Free Cash Flow and Unlevered Free Cash Flow. We believe such measures are commonly used by investors to evaluate our performance and that of our competitors. These measures are not presentations made in accordance with GAAP and our use of such terms varies from others in our industry. These measures should not be considered as alternatives to total revenue, net income (loss), operating income, total capital expenditures or any other performance measures derived in accordance with GAAP as measures of operating performance or operating cash flows or as measures of liquidity. These non-GAAP financial measures have important limitations as analytical tools and you should not consider them in isolation or as substitutes for analysis of our results as reported under GAAP. For definitions of these non-GAAP financial measures, a discussion regarding the limitations of their use and a reconciliation of these measures to the most directly comparable GAAP financial measures, see “Non-GAAP Financial Measures”, “Unaudited Pro Forma Information” and “Unaudited Reconciliation of GAAP to Non-GAAP and Pro Forma Financial Measures” in the Appendix to this presentation. Due to the inherent difficulty of forecasting the timing and amount of certain items that would impact net income, we are unable to reasonably estimate the related impact of such items to net income, the GAAP financial measure most directly comparable to Adjusted EBITDA. Accordingly, we are unable to provide a reconciliation of adjusted EBITDA to net income with respect to the updated 2016 and forward-looking guidance provided herein. For the same reasons, we are unable to address the probable significance of the unavailable information, which could have a significant impact on our final 2016 and full-year 2017 GAAP financial results. Pro Forma Subscriber & Financial Information The SEC requires that pro forma information be presented in a registrant’s periodic filings when events occur for which disclosure would be material to investors, including a significant business combination or the disposition of a significant portion of a business. The significance of an acquired or disposed business is determined based on the “significant subsidiary” tests specified in Regulation S-X, Article 11, Rule 1-02(w). In this regard, the Company has made certain acquisitions and divestitures which do not meet the “significant subsidiary” tests. Accordingly, the Company’s historical financial information as filed with the SEC does not contain pro forma financial information relating to those transactions. Nevertheless, this presentation makes certain pro forma adjustments to the historical subscriber and financial information of the Company giving effect to those transactions as if such transactions had been completed at the beginning of each period presented because we believe such information would be meaningful to investors by showing how such transactions might have affected the Company’s historical subscriber and financial information. For a discussion regarding such pro forma information and reconciliations to the most directly comparable GAAP financial measures, see “Unaudited Pro Forma Information” and “Unaudited Reconciliations of GAAP to Non-GAAP and Pro Forma Financial Measures” in the Appendix to this presentation.

Non-GAAP Financial Measures We have included certain non-GAAP financial measures in this presentation including Pro Forma Total Revenue, Adjusted EBITDA, Pro Forma Adjusted EBITDA, Pro Forma Capital Expenditures, Free Cash Flow and Unlevered Free Cash Flow. We believe that these non-GAAP measures enhance an investor’s understanding of our financial performance. We believe that these non-GAAP measures are useful financial metrics to assess our operating performance from period to period by excluding certain items that we believe are not representative of our core business. We believe that these non-GAAP measures provide investors with useful information for assessing the comparability between periods of our ability to generate cash from operations sufficient to pay taxes, to service debt and to undertake capital expenditures. We use these non-GAAP measures for business planning purposes and in measuring our performance relative to that of our competitors. We believe these non-GAAP measures are measures commonly used by Investors to evaluate our performance and that of our competitors. Adjusted EBITDA is defined by WOW! as net income (loss) before net interest expense, income taxes, depreciation and amortization (including impairments), gains (losses) realized and unrealized on derivative instruments, management fees to related party, the write-up or off of any asset, debt modification expenses, loss on extinguishment of debt, integration and restructuring expenses and all non-cash charges and expenses (including equity based compensation expense) and certain other income and expenses, as further defined in our credit facilities. Adjusted EBITDA is not a presentation made in accordance with generally accepted accounting principles in the United States (“GAAP”) and our use of the term Adjusted EBITDA varies from others in our industry. Adjusted EBITDA should not be considered as an alternative to net income (loss), operating income or any other performance measures derived in accordance with GAAP as measures of operating performance or operating cash flows or as measures of liquidity. Adjusted EBITDA has important limitations as an analytical tool and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. For example, Adjusted EBITDA: excludes certain tax payments that may represent a reduction in cash available to us; does not reflect any cash capital expenditure requirements for the assets being depreciated and amortized that may have to be replaced in the future; does not reflect changes in, or cash requirements for, our working capital needs; and does not reflect the significant interest expense, or the cash requirements necessary to service interest or principal payments, on our debt. Furthermore, although the Company has made certain acquisitions and divestitures which do not meet the SEC’s “significant subsidiary” tests which would require the presentation of pro forma financial information in its periodic filings, Total Revenue, Adjusted EBITDA and Capital Expenditures in this presentation are presented on a pro forma basis, giving effect to our acquisition of Bluemile, Inc. (“Bluemile”) on September 27, 2013, our increased investment in Anne Arundel Broadband (“AAB”) on May 1, 2014, our divestiture of the South Dakota systems on September 30, 2014, our acquisition of the operating assets of HC Cable Opco, LLC (dba “NuLink”) on September 9, 2016, and our divestiture of the Lawrence, KS system on January 12, 2017, as if such transactions had been completed at the beginning of each period presented. See “Unaudited Pro Forma Information” and “Unaudited Reconciliations of GAAP to Non-GAAP and Pro Forma Financial Measures” on the following pages and the accompanying tables for reconciliations of these non-GAAP financial measures to their most directly comparable GAAP financial measure. We define Unlevered FCF as Adjusted EBITDA minus capital expenditures. We define FCF as Unlevered FCF minus integration expense and cash interest. We believe these measures are useful metrics for analyzing our cash levels. However, Unlevered FCF and FCF should not be considered a substitute for operating cash flows determined in accordance with GAAP. In addition, these measures do not necessarily represent funds available for discretionary use and are not necessarily a measure of our ability to fund our cash needs. In addition, other companies in our industry may calculate free cash flow differently than we do, limiting its usefulness as a comparative measure.

Unaudited Pro Forma Information The Securities and Exchange Commission (the “SEC”) requires that pro forma financial information be presented in a registrant’s periodic filings when events occur for which disclosure would be material to investors, including significant business combinations or the disposition of a significant portion of the business. The significance of an acquired or disposed business is determined based on the “significant subsidiary” tests specified in Regulation S-X, Article 11, Rule 1-02(w). In this regard, although the Company has made certain acquisitions and divestitures, such transactions do not meet the “significant subsidiary” tests and, accordingly, the Company’s historical financial information as filed with the SEC does not contain pro forma financial information relating to those transactions. Nevertheless, this presentation makes certain pro forma adjustments to the subscriber and historical financial information of the Company as filed with the SEC because we believe such information would be meaningful to investors by showing how such transactions might have affected the Company’s historical financial statements. The unaudited pro forma subscriber and financial information in this presentation has been prepared giving effect to our acquisition of Bluemile on September 27, 2013, our increased investment in AAB on May 1, 2014, our divestiture of the Company’s South Dakota systems on September 30, 2014, our acquisition of the operating assets of NuLink on September 9, 2016 and our divestiture of the Lawrence, KS system on January 12, 2017, as if such transactions had been completed at the beginning of each period presented. The unaudited pro forma subscriber and financial information is for informational purposes only and does not purport to represent what our results of operations or financial information would have been if such transactions had occurred at any date, nor does such information purport to project the results of operations for any future period. The unaudited pro forma condensed combined financial information in this presentation was prepared based on Bluemile’s, AAB’s and NuLink’s unaudited financial information for the respective periods presented. The historical unaudited subscriber and financial information has been adjusted to give pro forma effect to events that are directly attributable to such transactions, factually supportable and expected to have a continuing impact on the combined results. The unaudited pro forma subscriber and financial information herein does not reflect non-recurring charges that have been incurred in connection with the transactions and related financings, including legal fees, broker fees and accounting fees. See “Unaudited Reconciliations of GAAP to Non-GAAP and Pro Forma Financial Measures” in the following tables for reconciliations of such pro forma information to the most directly comparable GAAP financial measures. The unaudited pro forma information herein should be read in conjunction with the information contained in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” the consolidated financial statements and the accompanying notes appearing in our most recently filed Form 10-K for the year ended December 31, 2015 as filed with the SEC on March 17, 2016 and subsequent quarterly filings on Form 10-Q. Due to the inherent difficulty of forecasting the timing and amount of certain items that would impact net income, we are unable to reasonably estimate the related impact of such items to net income, the GAAP financial measure most directly comparable to Adjusted EBITDA. Accordingly, we are unable to provide a reconciliation of adjusted EBITDA to net income with respect to the updated 2016 and forward-looking guidance provided herein. For the same reasons, we are unable to address the probable significance of the unavailable information, which could have a significant impact on our final 2016 and full-year 2017 GAAP financial results. Furthermore, we have not yet filed the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 with the SEC. When the Company ultimately files its Annual Report on Form 10-K with the SEC, actual results and financial information related to the year and quarter ended December 31, 2016 could differ materially from those reflected in the forward-looking statements contained herein as a result of a variety of factors, many of which are beyond the Company’s control. The Company assumes no responsibility to update or revise any forward-looking statements as a result of new information or future developments.
