FLOW INTERNATIONAL DELAYS SECOND QUARTER

FORM 10-Q FILING

KENT, Wash., December 15, 2004 – Flow International Corporation (Nasdaq: FLOW), the world’s leading developer and manufacturer of ultrahigh-pressure waterjet technology equipment used for cutting, cleaning (surface preparation) and food safety applications, today announced that it does not intend to file a Form 12b-25 notification of delayed filing with the Securities and Exchange Commission for its quarterly report on Form 10-Q for the fiscal 2005 second quarter ended October 31, 2004, as previously announced.

A 12b-25 filing would have provided the Company a five-day extension to file its second quarter Form 10-Q on or before December 20, 2004. However, the Company does not currently anticipate that it will be able to file its second quarter Form 10-Q within that timeframe. Before the Company can file its second quarter Form 10-Q it needs to first file an amended Form 10-K/A and the 10-Q for the first quarter. As soon as practicable after work on its previously announced review and reconciliation of certain historical inter-Company transactions has been completed, the Company intends to file an amended Form 10-K/A for the fiscal year ended April 30, 2004, to be followed by its Form 10-Qs for the fiscal 2005 first quarter and then the second quarter.

The Company intends to announce details regarding its fiscal 2005 second quarter results conference call subsequent to the filing of its second quarter fiscal 2005 Form 10-Q.
