PACCAR Announces Increased Quarterly Dividend

April 26, 2005, Bellevue, Washington PACCARs Board of Directors declared a regular quarterly cash dividend in the amount of twenty-one cents ($.21) per share, payable on June 6, 2005, to stockholders of record at the close of business on May 19, 2005.  This is a 5 percent increase compared to the previous regular quarterly dividend of twenty cents ($.20) per share.  PACCARs record profit and cash flow performance has enabled it to enhance its position as a leading technology company in the capital goods and financial services industry worldwide.  PACCAR has increased its regular quarterly dividend by 180 percent in the last six years, said Mark C. Pigott, chairman and chief executive officer.

PACCAR has earned a net profit for 66 consecutive years and has paid a dividend every year since 1941, noted Pigott.  PACCARs global truck brands Peterbilt, Kenworth and DAF are leaders in reliability and resale value, which creates a superior life-cycle cost advantage for our customers.  In addition, PACCAR shareholder return is excellent.  The company has again outperformed the Standard & Poors 500 Index for the previous one-, five- and ten-year time periods.

At the annual stockholder meeting held today, the stockholders reelected John M. Fluke, Jr., Stephen F. Page and Michael A. Tembreull as PACCAR directors for a three-year term expiring in 2008.

PACCAR is a global technology leader in the design, manufacture and customer support of high-quality light-, medium- and heavy-duty trucks under the Kenworth, Peterbilt, DAF and Foden nameplates.  It also provides financial services and distributes truck parts related to its principal business.  In addition, the Bellevue, Washington-based company manufactures winches under the Braden, Gearmatic and Carco nameplates.
