WARRENVILLE, Ill. (August 24, 2009) – Navistar International Corporation (NYSE: NAV) today celebrated 100 years of trading of its common stock on the New York Stock Exchange (NYSE). To commemorate the anniversary, Dan Ustian, Navistar chairman, president and chief executive officer, and the company’s Board of Directors, rang The Closing Bell® on the NYSE.

"In our 100 years on the world’s premier market for stocks, we have a proud heritage of being at the forefront of agriculture, transportation and manufacturing in this country,” said Ustian. “This is a great achievement and a testament to the growth and performance of our company.

“This is a well-deserved gesture of appreciation to the employees, customers and investors who continue to drive our success and we’re honored to have been given this opportunity to celebrate Navistar’s innovations and achievements,” he said.
