Advanced Marketing Services, Inc. Will Not File Form 10-K By Extended June 29, 2004 Deadline.

SAN DIEGO -- Advanced Marketing Services, Inc. (NYSE: MKT), ("AMS" or the "Company"), a leading global provider of customized wholesaling and distribution services to book retailers and publishers, announced that it will not file its Form 10-K for the fiscal year ended March 31, 2004 by the June 29, 2004 extended deadline afforded by Rule 12b-25 (the "Rule") under the Securities Exchange Act of 1934, as amended. The Company filed on June 14, 2004, a notice on Form 12b-25 with the Securities and Exchange Commission, which granted under the Rule an automatic fifteen-day extension to the Form 10-K filing deadline.

As the Company has previously announced, it is in the process of restating financial information for the fiscal year ended March 31, 2003 and certain prior fiscal years. The restatement relates primarily to certain cooperative advertising practices and related accounting.

The Company will file its Form 10-K for the fiscal year ended March 31, 2004 upon, among other things, completion of the restatement and related internal review, and when the independent auditors have finished their audit of the restated financial statements for the fiscal years ended March 31, 2003 and 2002, and their audit of the financial statements for the fiscal year ended March 31, 2004.

AMS has devoted, and will continue to devote, significant resources to expedite the work necessary to file its fiscal 2004 Form 10-K as soon as possible. However, there can be no assurances as to when the restatement and the related internal review and the independent audit of the financial statements to be included in the 2004 Form 10-K will be completed and the fiscal 2004 Form 10-K filed.
