Non-GAAP Financial Measures & Pro Forma Financial Information We have included certain non-GAAP financial measures in this presentation, including Adjusted EBITDA and Pro Forma Adjusted EBITDA. We believe Adjusted EBITDA and Pro Forma Adjusted EBITDA are measures commonly used by investors to evaluate our performance and that of our competitors. Adjusted EBITDA and Pro Forma Adjusted EBITDA are not presentations made in accordance with GAAP and our use of the terms Adjusted EBITDA and Pro Forma Adjusted EBITDA varies from others in our industry. Adjusted EBITDA and Pro Forma Adjusted EBITDA should not be considered as alternatives 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 and Pro Forma Adjusted EBITDA 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 Financial Information” and “Unaudited Reconciliation of GAAP to Non-GAAP Financial Measures” in the Appendix to this presentation.

Appendix

Non-GAAP Financial Measures We have included certain non-GAAP financial measures in this presentation including Adjusted EBITDA and Pro Forma Adjusted EBITDA. 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, Adjusted EBITDA in this presentation is (i) sometimes presented on a Pro Forma basis, giving effect to our merger with Knology, Inc. (“Knology”) and related July 17, 2012 financing and other WOW! and Knology transactions as if they had been completed at the beginning of each period presented (see “Unaudited Pro Forma Financial Information” on the following pages for complete discussion), and (ii) sometimes further adjusted to include the estimated run-rate cost savings in connection with our Knology merger and transitioning our billing system from one provider to another which is calculated in accordance with the definitions of our senior secured credit facilities. See “Unaudited Reconciliation of GAAP to Non-GAAP Financial Measures” on the following pages and the accompanying tables for reconciliations of Adjusted EBITDA to our net income (loss), which is the most directly comparable GAAP financial measure.

Unaudited Pro Forma Financial Information This presentation contains unaudited pro forma financial information which has been developed by applying pro forma adjustments to the individual historical unaudited condensed consolidated financial statements of WOW! and Knology and unaudited financial information of Bluemile. The unaudited pro forma financial information has been prepared giving effect to our merger with Knology and related July 17, 2012 financing and the acquisition of certain operating assets of Bluemile on September 27, 2013 as if they had been completed at the beginning of each period presented. The unaudited pro forma 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 the Knology merger and related financing 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 was prepared based on WOW!’s and Knology’s historical unaudited financial statements and Bluemile’s unaudited financial information for the respective periods presented. The historical consolidated financial information has been adjusted to give effect to pro forma 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 financial information 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. The unaudited pro forma financial information 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 Registration Statement and our Form 10-K for the year ended December 31, 2013 as filed with the SEC.
