Item 2.02. Results of Operations and Financial Condition.

     The  disclosure  set  forth  in Item  7.01 of this  report  concerning  the
unaudited data and other information of Mediacom Communications Corporation (the
"Company")  for the three months ended March 31, 2006  (including  the paragraph
stating that the information is preliminary in nature) is incorporated herein by
reference.


Item 7.01. Regulation FD Disclosure.

Mediacom  Communications  Corporation  Announces Selected Preliminary  Unaudited
First Quarter 2006 Results

     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 proposed  refinancings  of certain  existing  senior
secured term loan facilities for the operating  subsidiaries of Mediacom LLC and
Mediacom Broadband LLC.

     Since the first quarter of 2006 has only recently ended, the unaudited data
and other  information  that follows is  preliminary in nature and is based only
upon  what  is  available  to the  Company  as of the  date of  this  Form  8-K.
Accordingly,  this  information  is subject in all respects to the completion of
disclosure  controls and procedures required to finalize the Company's financial
statements  and  other  information  for the  reporting  period,  which  will be
included in the  Company's  Form 10-Q for the three months ended March 31, 2006.
Furthermore,  reference  is made to operating  income  before  depreciation  and
amortization   (excluding  non-cash  stock  compensation  charges)  (hereinafter
referred to as Adjusted OIBDA),  which is not a financial measure  calculated in
accordance with generally accepted accounting principles (GAAP).  Adjusted OIBDA
should not be regarded as an alternative to operating income,  net income or net
loss as an indicator of operating  performance,  nor should it be  considered in
isolation or as a substitute for financial  measures prepared in accordance with
GAAP. However,  the Company cannot at this time, given the preliminary nature of
this  information,  provide a  reconciliation  of  Adjusted  OIBDA to  operating
income,  which  the  Company  believes  is its  most  directly  comparable  GAAP
financial measure. Investors should therefore exercise caution in relying on the
unaudited data and other  information  contained  herein and should not draw any
inferences from this information  regarding  financial or operating data that is
not  discussed  herein.  There  can be no  assurance  that  the  actual  amounts
ultimately filed in the Company's Form 10-Q for the three months ended March 31,
2006, will not be materially  different than the amounts  disclosed in this Form
8-K.

     Revenues  for the three  months  ended March 31,  2006,  are expected to be
approximately $289.3 million,  representing an 8.7% increase over the prior year
period.  Adjusted OIBDA is expected to grow about 8.5% over the first quarter of
2005.
