On November 15, 2010, the Company announced that it had entered into a definitive merger agreement with Rocco B. Commisso, Mediacom’s founder, Chairman and Chief Executive Officer, and an entity formed by Mr. Commisso. A special meeting of stockholders will be held on March 4, 2011 to vote on the merger agreement, pursuant to which all outstanding shares of Mediacom common stock that Mr. Commisso does not already own will be converted into $8.75 per share in cash.

Mediacom is releasing these preliminary results to provide its stockholders with additional financial information prior to the upcoming special meeting of stockholders. The Company anticipates that if the merger agreement is adopted by the requisite vote of stockholders, the merger will be consummated on or about the date of the stockholder meeting. In light of that expectation, the Company does not plan to make a further earnings release after the 2010 audit is complete or to hold an investors’ conference call.

Additional Information About the Merger

Mediacom has filed a definitive proxy statement describing the proposed transaction with the Securities and Exchange Commission (“SEC”). STOCKHOLDERS ARE ADVISED TO READ THE DEFINITIVE PROXY STATEMENT BECAUSE IT CONTAINS IMPORTANT INFORMATION ABOUT THE MERGER AND ITS PARTICIPANTS. Stockholders may obtain a free copy of the definitive proxy statement and other documents filed by Mediacom at the SEC’s Web site (www.sec.gov) and from Mediacom.
