WARRENVILLE, Ill. (June 27, 2008) Paving the way to relisting on the New York Stock Exchange, Navistar International Corporation (Other OTC: NAVZ) today filed first and second quarter 2008 form 10-Qs with the Securities and Exchange Commission.

“We’re happy to be caught up with our financial reporting. We will keep our focus on delivering on our commitments to shareholders,” said Daniel C. Ustian, Navistar chairman, president and chief executive officer. “In one of the weakest commercial truck markets in recent history, we are set to surpass our $15 billion revenue goal for 2009 a year early and to realize nearly $1 billion in manufacturing segment profit.”

The company reported net sales and revenue of $6.9 billion for the first half of fiscal 2008, a 13 percent increase over the same period in 2007. Manufacturing segment profit was $424 million, doubling 2007 performance of $208 million. Net income was $162 million, or $2.22 per diluted share, an improvement of $175 million or $2.41 per diluted share over the first half of fiscal 2007.

“We look forward to our return to a premier exchange so that we can offer shareholders the best venue for optimal liquidity,” Ustian said.

Navistar common stock will resume trading June 30 on the New York Stock Exchange under its original ticker symbol NAV; Navistar preferred stock will trade under NAVPrD.

SEC Regulation G
The financial measures presented below are unaudited and non-GAAP; they reflect a change in segment reporting methodology beginning in 2007. This is not in accordance with, or an alternative for, U.S. generally accepted accounting principles (GAAP). The non-GAAP financial information presented herein should be considered supplemental to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. However, we believe that non-GAAP reporting, giving effect to the adjustments shown in the reconciliation below, provides meaningful information and therefore we use it to supplement our GAAP reporting by identifying items that may not be related to the core manufacturing business. Management often uses this information to assess and measure the performance of our operating segments. We have chosen to provide this supplemental information to investors, analysts and other interested parties to enable them to perform additional analyses of operating results, to illustrate the results of operations giving effect to the non-GAAP adjustments shown in the below reconciliations, and to provide an additional measure of performance.
