WARRENVILLE, Ill. (April 8) – Navistar International Corporation (NYSE: NAV) today announced that the company raised its guidance of earnings for its 2010 fiscal year ending Oct. 31, 2010. For fiscal year 2010, net income attributable to Navistar International Corporation is expected to be in the range of $198 million, or $2.75 per diluted share, and $234 million, or $3.25 per diluted share primarily related to increased military orders.

As the company previously said, based on continued economic recovery, it anticipates that total truck industry retail sales volume for Class 6-8 trucks and school buses in the United States and Canada for its fiscal year ending Oct. 31, 2010, will be in the range of 195,000 to 215,000 units. Truck industry volume in fiscal 2009 was 181,800 units, which was during the worst truck markets in more than 47 years.

Currently, Navistar is evaluating the full impact of the recently enacted Patient Protection and Affordable Care Act on its business. Many companies have disclosed increases in tax expense due to changes in tax treatment of the Medicare Part D drug subsidy. Navistar has a full valuation allowance against these deferred tax assets, therefore these changes are expected to have no current impact on income tax expense.
