WOW! TO SELL CHICAGO FIBER NETWORK TO VERIZON

Englewood, CO (August 1, 2017) — WideOpenWest, Inc. (“WOW!” or the “Company”) (NYSE: WOW) announced today that it has entered into a definitive agreement to sell a portion of its fiber network in the Company’s Chicago market to a subsidiary of Verizon (NYSE: VZ) for $225 million in cash. In addition, WOW! and Verizon will enter into a new agreement pursuant to which WOW! will complete the build-out of the network in exchange for approximately $50 million (which approximates WOW!’s remaining estimate to complete the network build-out), payable as the remaining network elements are completed.   The final build-out of the network is expected to be completed during the second half of 2018 and, when completed, will provide back-haul services to over 500 macro-cell wireless sites and more than 500 small-cell wireless sites.

The transaction is subject to receipt of various consents and approvals as well as other customary closing conditions and is expected to close by early in the first quarter of 2018.  WOW!’s financial outlook for the twelve month period ending December 31, 2017, previously included Revenues and Adjusted EBITDA attributable to the network totaling approximately $13.7 million and $13.2 million, respectively.  A portion of the proceeds are expected to be used to pay-down WOW!’s existing debt balances.

“We’re pleased to have reached an agreement to sell our Chicago fiber asset to Verizon,” said Steven Cochran, Chief Executive Officer of WOW!. “This transaction is consistent with WOW!’s stated objective of reaching an optimal leverage profile and allows us to continue to focus on areas of growth for residential and commercial services with our internet centric-outlook and emphasis on expanding our markets through edge-out builds.”

Morgan Stanley & Co. LLC and Kirkland & Ellis LLP served as exclusive financial and legal advisors, respectively, to WOW! as part of this transaction.
