“In light of the seriousness with which we view corporate disclosure matters, we are moving aggressively to review and, if necessary, correct our financial statements,” said Carreker’s Chairman and Chief Executive Officer, John D. (Denny) Carreker. “We believe that many of the timing issues and related problems stem from a Company revenue guideline, which allows for contracts signed and dated by the end of a quarter to be physically received in Carreker’s legal department as late as noon on the next business day following the end of the quarter. We set the contract receipt deadline to accommodate the mechanics of delivery from our global operations. We are working closely with the Special Committee and our independent auditors to address these issues as quickly as possible, and are taking steps to insure these problems do not recur in the future,” said Mr. Carreker.

The Company believes it may be required to restate its financial statements for prior periods. If required, the Company will file amendments to its Form 10-Ks and Form 10-Qs for the affected periods, and it cautions that its historical financial statements for prior periods should not be relied upon.

In light of these developments, Carreker is postponing its earnings release for the third quarter, ended October 31, 2002. Management will hold a conference call to discuss its results for the third quarter ended October 31, 2002, as well as the status of the review, on December 23, 2002 at 5:00 p.m. Eastern Time.
