Capital Investments Improve Efficiency

PACCAR (Nasdaq:PCAR) reported good earnings and revenues for the third quarter and first nine months of 2008. “There are over 1.5 million PACCAR commercial vehicles in service worldwide, the largest population in our history,” said Mark C. Pigott, chairman and chief executive officer. “These vehicles generate steady aftermarket revenues and many of them also contribute financial services income, which partially offset reduced truck build rates worldwide. In these turbulent times, PACCAR is experiencing lower truck demand in Europe, Mexico and Australia, and continued softness in the U.S. and Canada, which will reduce financial results in the fourth quarter of 2008 and into 2009.” Pigott added, “As in previous cyclical downturns, the company is rigorously aligning operating costs with market conditions while selectively investing in capital projects and new products that will generate excellent customer benefits. PACCAR’s products, manufacturing facilities and distribution centers are the best in our 103-year history and position the company strongly when the industry returns to a normal vehicle replacement cycle. I am very proud of our 20,000 employees delivering third quarter profits comparable to the same period last year.”

PACCAR earned $299.0 million ($0.82 per diluted share) for the third quarter of 2008 compared to $302.3 million ($0.81 per diluted share) earned in the third quarter last year. Third quarter net sales and financial services revenues were $4.00 billion. Net sales and financial services revenues for the first nine months of 2008 were $12.06 billion. PACCAR reported nine-month net income of $904.8 million ($2.47 per diluted share), compared to $966.2 million ($2.58 per diluted share) in 2007. “PACCAR’s financial strength, global diversification, high-quality products and strong distribution network are critical elements that contribute to its profitable results, especially in an uneven economy,” said Mike Tembreull, PACCAR vice chairman.

Global Truck Markets

DAF’s premium vehicles are the quality and resale value leaders in Europe. “Industry truck sales in Western and Central Europe above 15 tonnes are expected to be comparable this year to the 340,000 units sold in 2007,” shared Aad Goudriaan, DAF Trucks president. “After robust growth for a number of years, the European economy and truck markets are now slowing. As a result of the recent slowdown in customer demand, DAF will reduce its build rate during October and anticipates the 2009 commercial vehicle market will reflect the slower economy. European industry truck sales in 2009 are difficult to predict due to economic uncertainty, but they could be at a level of 260,000-300,000 units.”

“Declining housing starts and auto production have impacted U.S. and Canadian Class 8 truck sales throughout 2008,” said Dan Sobic, PACCAR executive vice president. “Industry retail sales are expected to be approximately 150,000 vehicles this year. Industry retail sales are projected to improve slightly in the second half of 2009 and are expected to be in the range of 170,000-210,000 as fleets replace vehicles after several years of lower purchases. Several of our major customers are reporting increased third quarter income due to good freight traffic and lower fuel prices.” Sobic noted, “Kenworth and Peterbilt continue to achieve a strong share of industry sales due to their superior quality, reliability and industry-leading resale value.”

Export Sales

PACCAR International delivers Kenworth, Peterbilt and DAF vehicles to customers in over 100 countries. “Despite the current global economic environment, PACCAR is experiencing good demand from Latin America and Middle East customers, particularly for Kenworth off-highway and oil well servicing vehicles,” said Claire Hargrave, PACCAR International general manager.

Quarterly Dividend

The PACCAR Board of Directors approved a fourth quarter regular quarterly cash dividend in the amount of $.18 (eighteen cents), payable on December 5, 2008, for shareholders of record on November 18, 2008. Over the last five years PACCAR has increased its regular quarterly dividend by an average of 23 percent per year and has paid a dividend every year since 1941. PACCAR purchased $29.8 million of its shares in the third quarter.

Capital Investment Program Update

Construction of PACCAR’s new engine production facility in Columbus, Mississippi, continues on schedule. The technologically advanced and environmentally friendly facility will incorporate leading-edge manufacturing and diagnostic processes. “This industry-leading engine facility is progressing well and is scheduled to be completed in late 2009,” said Jim Cardillo, PACCAR president. PACCAR’s premium 12.9-liter and 9.2-liter diesel engines scheduled to be manufactured in Columbus will utilize selective catalytic reduction (SCR) technology to meet the oxides-of-nitrogen (NOx) requirements of the 2010 EPA diesel engine emissions regulations. Cardillo added, “Field trials of the PACCAR engine in Kenworth and Peterbilt fleets are achieving excellent results.”

PACCAR’s new state-of-the-art Parts Distribution Center (PDC) near Budapest, Hungary, was opened. The 260,000-square-foot facility is strategically located to provide daily aftermarket parts support to the growing network of DAF dealers and customers in Central and Eastern Europe. “PACCAR Parts now operates 13 PDCs throughout the world, providing daily delivery of aftermarket parts to PACCAR’s dealers and customers,” said Rick Gorman, PACCAR Parts general manager and PACCAR vice president.

PACCAR has also invested nearly $60 million to install state-of-the-art robotic cab paint facilities at its Kenworth plant in Chillicothe, Ohio, and its Peterbilt plant in Denton, Texas. These investments have enhanced product quality and increased productivity.

Financial Services Companies Achieve Good Results in Difficult Markets

PACCAR Financial Services (PFS) has a portfolio of 169,000 trucks and trailers, with total assets of $10.7 billion. PACCAR Leasing, a major full-service truck leasing company in North America with a fleet of over 32,000 vehicles, is included in this segment.

Third quarter pretax income was $45.5 million compared to the $73.4 million earned in the third quarter last year. Third quarter revenues rose to $322.8 million compared to $313.2 million in the same quarter of 2007. For the nine-month period, revenues increased to $970.7 million from $864 million during the same period a year ago and pretax income was $171.5 million compared with $207.9 million in 2007. Profit was reduced due to an increase in the provision for credit losses due to higher truck repossessions in the U.S. and Canada. The provision for credit losses in the third quarter of 2008 was $34.2 million versus $24.4 million in the second quarter of 2008.

“PACCAR Financial Services profitably supports the sale of PACCAR trucks in 19 countries on three continents with a comprehensive portfolio of finance, lease and insurance products,” said Ron Armstrong, senior vice president. “PACCAR’s strong balance sheet, complemented by its AA- credit rating, enables PFS to offer competitive retail financing to Kenworth, Peterbilt and DAF dealers and customers. Good margins and credit quality, as well as thorough portfolio management, are providing solid earnings.” Armstrong added, “Some North American trucking companies are being impacted by the difficult credit markets, fuel pricing and the slower economy. European truck customers are also beginning to experience a slowing European economy.”

Kenworth Truck Company achieved the highest ranking in customer satisfaction among Class 8 truck owners in the Over the Road and Vocational Segments, according to the recently released J.D. Power and Associates 2008 Heavy Duty Truck Customer Satisfaction Study^SM(1). “Kenworth swept the product quality awards in 2008, the same as in 2007,” said Bob Christensen, PACCAR senior vice president. “This recognition is wonderful for our customers. Kenworth has an outstanding record of delivering industry-leading customer satisfaction in performance, quality and low cost of ownership.” Since 1993, PACCAR has earned 26 J.D. Power awards with the closest competitor earning nine.

DAF Trucks won the “Fleet Truck of the Year” award for its CF85 model for the eighth time at the recent Motor Transport Awards in London.
