Exhibit 99 NORDSON REVISES FINANCIAL OUTLOOK FOR SECOND QUARTER AND FULL-YEAR 2005 WESTLAKE, Ohio, April 6 /PRNewswire-FirstCall/ -- Nordson Corporation (Nasdaq: NDSN) today announced a revision in the company's revenue outlook for the second quarter ending May 1, 2005. Revenue for the quarter is now expected to increase four percent to six percent. Sales volume is expected to be up one percent to three percent, with the remainder of the expected increase traced to favorable currency associated with the weaker dollar. Earnings expectations for the second quarter will be affected by the gross margin impact of this revision. "A softness in European and Japanese order activity within our adhesive business segment has prompted us to adjust our revenue outlook for the second quarter," said Edward P. Campbell, Nordson Chairman and Chief Executive Officer. "For the fiscal year we are expecting volume growth, exclusive of acquisitions, to be in the four percent to five percent range," Campbell added.
