Item 7.01. Regulation FD Disclosure. Mediacom Broadband LLC Announces Preliminary Unaudited First Quarter 2006 Revenues and Customer Information The Company is providing the following unaudited and other information for the first quarter of 2006 because such information is being given to potential investors with respect to a proposed refinancing of certain existing senior secured term loan facilities for its operating subsidiaries.
