      On November 3, 2004, The Robert Mondavi Corporation (the "Company") entered into a definitive merger agreement with Constellation Brands, Inc. ("Constellation"), pursuant to which Constellation will acquire all the outstanding shares of the Company. In light of this transaction, the Company is no longer pursuing its previously announced restructuring and, accordingly, no longer expects to incur the full amount of the previously announced estimated pre-tax charges related to such restructuring. As a result, the Company is in the process of finalizing its unaudited financial statements for the three-month period ended September 30, 2004 to reflect this recent development. Because this process is not yet complete and could not be completed by the Company without unreasonable effort or expense, the Company is unable to file its quarterly report on Form 10-Q for this period at this time. The quarterly report on Form 10-Q for this period will be filed no later than November 15, 2004.

     (2) Have all other periodic reports required under Section 13 or 15(d) of the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the registrant was required to file such report(s) been filed? If answer is no, identify report(s).

x Yes    o No

     (3) Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof?

x Yes    o No

     If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.

      The Company issued the attached press release on October 27, 2004, announcing its first quarter results. The Company expects that its financial statements contained in the form 10-Q will be consistent with its publicly announced results, taking into account the fact that the Company no longer expects to incur the full amount of the previously announced estimated pre-tax charges related to restructuring.
