FOR IMMEDIATE RELEASE
DONALDSON COMPANY TO APPEAL JUDGMENT
MINNEAPOLIS, Aug. 13 — Donaldson Company, Inc. (NYSE:DCI) announced today the outcome of post trial motions in the jury trial between Donaldson and Engineered Products Company, Inc. (“EPC”). In 1998, EPC filed a patent infringement lawsuit against Donaldson in the U.S. Federal District Court for the Northern District of Iowa. On May 11, 2004, the jury found in favor of EPC on its willful infringement claims against Donaldson. On August 12, 2004, the Court ruled that damages should be approximately $16.0 million. Donaldson intends to vigorously challenge the judgment and will appeal the decision to the Federal Circuit Court of Appeals. This appeal could take up to two years or longer. EPC’s patent expired on May 1, 2001 and will not impact Donaldson’s ongoing business operations. Donaldson confirms previous guidance of delivering its 15th consecutive year of double-digit earnings growth when it issues its fourth quarter earnings release on August 31.
