PACCAR Increases Regular Quarterly Cash Dividend

April 29, 2014, Bellevue, Washington – PACCAR Inc’s Board of Directors today declared an increase to the regular quarterly cash dividend to twenty-two cents ($.22) per share from twenty cents ($.20), payable on June 5, 2014, to stockholders of record at the close of business on May 19, 2014.

“The increase in the quarterly dividend reflects PACCAR’s strong operating results,” said Mark Pigott, PACCAR executive chairman. “In the first quarter of 2014, net income increased to $273.9 million ($.77 per diluted share) as a result of increased truck sales in North America and growth in financial services assets and aftermarket revenues worldwide.” PACCAR has earned a net profit for 75 consecutive years and has paid a dividend every year since 1941. The company’s stock has outperformed the Standard & Poor’s 500 index for the previous one-, five-, ten- and twenty-year time periods.
