PACCAR Highlighted as a Leading Manufacturing Company by Industry Week Magazine

July 21, 2005, Bellevue, Washington PACCAR Inc has earned the distinction of being selected by Industry Week magazine as one of the 50 best manufacturing companies in the United States.  It is an honor for PACCAR to be recognized with other leading companies including Dell, Johnson & Johnson, Chevron and 3M, said Mark C. Pigott, chairman and chief executive officer.  As the company celebrates its 100-year anniversary during 2005, this wonderful recognition reflects the dedication and talent of PACCAR employees worldwide.

To select the top 50 performing companies, Industry Week evaluated three-year performance measures including revenue growth, profit margin, asset turnover, inventory turns, return on assets and return on equity.  Performance for 2004 was weighted more heavily in the survey.

PACCARs global diversification has been integral to the companys steady revenue and profit growth, noted Mike Tembreull, vice chairman.  During 2004, over 50 percent of PACCARs revenues were generated outside the United States.  During the past decade, PACCARs earnings per share have grown by 16 percent per annum versus 7 percent for the S&P 500.  PACCARs return on equity has averaged 21.5 percent during the last three years and was 27.9 percent for 2004.

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 and DAF nameplates.  It also provides financial services and information technology and distributes truck parts related to its principal business.
