Navistar Postpones New York Analyst Meeting

WARRENVILLE, Ill.--Dec. 1, 20054, 2005--Navistar International Corporation , the nation's largest combined commercial truck and mid-range diesel engine producer, today postponed a scheduled meeting with security analysts and shareowners because the company's external audit for Fiscal 2005 is still in progress.

"As a company, we have high standards and our audit process is taking longer than expected," said Daniel C. Ustian, Navistar chairman, president and chief executive officer. "We intend for this meeting to take place at the first opportunity when we are able to provide complete Fiscal 2005 results and 2006 guidance."

Financial results for 2005 will be announced upon completion of the company's external audit and a Form 10-K is anticipated to be filed on time in January.
