Navistar Delivers Strong 4Q Adjusted Earnings of $3.37 Per Share; Achieves Best Full-Year Earnings Performance Since 2008

Navistar International Corporation (NYSE:NAV) today announced strong fourth quarter and full-year earnings performance reflecting the company’s continued execution of its strategy. Drivers of this performance included higher revenues and improved margins in its core North America truck business; sustained military sales; and an engine business that returned to profitability in the second half of the year. The company also saw revenues from outside of North America grow to more than $3 billion, as well as ongoing benefits from its engineering integration.

"We are pleased that we have finished the year strong and delivered solid fourth quarter results across all segments,” said Daniel C. Ustian, Navistar chairman, president and chief executive officer. "Not only did we deliver on 2011 commitments, we continued to invest in our strategy and set the foundation for a strong 2012.”

Reported net income for the fourth quarter ended October 31, 2011, of $255 million, equal to $3.48 diluted earnings per share, versus a year-ago net income of $44 million, equal to $0.61 diluted earnings per share. Adjusted net income for the fourth quarter 2011 was $247 million, or $3.37 diluted earnings per share.

Net income for fiscal year 2011 was $1.7 billion, equal to $22.64 diluted earnings per share, versus net income for fiscal 2010 of $223 million, equal to $3.05 diluted earnings per share. Adjusted net income was $402 million, or $5.28 diluted earnings per share. Adjustments impacting both the fourth quarter and fiscal year 2011 include the net impact of an income tax valuation allowance release, costs associated with the restructuring of North American manufacturing operations, engineering integration and the impact of the Medicare Part D court ruling.

In the fourth quarter, the company saw increases in worldwide unit chargeouts in both its traditional North American and global businesses while maintaining a strong market share position. The company purchased 2.7 million shares of its stock in the fourth quarter and ended the year with a manufacturing cash balance of $1.2 billion. Navistar is on track to complete the full $175 million stock repurchase program in early 2012.

"We expect the industry to continue its steady recovery,” said Ustian. "We will continue to leverage our market leading North American businesses, invest in new products and expand further into global markets, while effectively controlling our costs.”

Segment Results

Truck — For the fourth quarter 2011, the truck segment recorded $287 million in manufacturing segment profit, compared with a year-ago fourth quarter manufacturing segment profit of $86 million. For the fiscal year 2011, the truck segment recorded an adjusted profit of $509 million, excluding charges of $173 million for the restructuring of its North American manufacturing operations and engineering integration, compared with a fiscal year 2010 profit of $424 million.

Fiscal 2011 included a full-year revenue increase of 19 percent supported by record volume in Latin America, improved product mix, increased Class 8 and Class 6/7 truck chargeouts and improved pricing mainly through the use of the company’s proprietary 2010 engines. The segment also saw strong cost performance as a result of a solid order board, improved logistics performance and utilization of the company’s flexible manufacturing strategy.

This was all achieved in a year of lower military revenue, continued global investment, higher commodity costs, and increased product development costs to support future growth.

Engine — For the fourth quarter 2011, the engine segment recorded $58 million in profit, compared with a year-ago fourth quarter loss of $17 million. For the fiscal year 2011, the engine segment posted a profit of $84 million compared to a prior year profit of $51 million. The increase in year-over-year profit was driven by strong intercompany sales and margins from MaxxForce® Big-Bore engines and continued strong performance in South America, partially offset by increased engineering product development and higher adjustments to pre-existing warranties.

Parts — For the fourth quarter 2011, the parts segment recorded $87 million in profit, compared with a year-ago fourth quarter profit of $77 million. For the fiscal year, Navistar’s commercial parts business grew 17 percent, reflecting the company’s growth in truck and engine market share, the overall improvement in industry volume, and an increase in all-makes sales. Total parts segment profit in fiscal 2011 was $287 million, compared with a year-ago profit of $266 million.

Financial Services — For the fourth quarter 2011, the financial services segment recorded $27 million in profit, compared with a year-ago fourth quarter profit of $34 million. During fiscal year 2011, the segment earned $129 million, compared to $95 million in fiscal year 2010. The increase in year-over-year profits included decreased administrative costs and a lower provision for credit losses, slightly offset by a lower net interest margin. Liquidity remains strong and on better terms than previously available.

Corporate — The impact of higher taxes reduced earnings by approximately $0.29 a share, prior to the positive impact of the valuation adjustment.

(A) In 2011, the Truck segment profit included $173 million of charges related to the restructuring of its North American manufacturing operations and engineering integration costs.

(B) In 2011, the Engine segment recognized a $10 million gain on the extinguishment of a liability related to an equipment financing transaction. Previously, such gains were not material and were recorded within Corporate.

(C) Total sales and revenues in the Financial Services segment include interest revenues of $285 million, and $270 million for 2011 and 2010, respectively.

(D) Beginning in the second quarter of 2011, certain purchases from the Engine segment by the Parts segment are recorded at market-based pricing. All other intersegment purchases from the Truck and Engine segments by the Parts segment continue to be recorded at standard production cost. The effect of this change did not have a material impact on our segment reporting.

(F) Effective with the fourth quarter of 2011, the company’s master intercompany agreement was amended to provide the ability to adjust fees and rates paid by the Truck and Parts segment to the Financial Services segment for changes in the Financial Services segments capital structure. In the fourth quarter of 2011 as a result of the amendment, the Financial Services segment refunded the Truck and Parts segments $11 million for financing fees.

SEC Regulation G Non-GAAP Reconciliation

The financial measures presented below of adjusted income and adjusted diluted earnings per share attributable to Navistar International Corporation, manufacturing segment profit, and adjusted manufacturing segment profit are unaudited and not in accordance with, or an alternative for, financial measures presented in accordance with 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.

We believe manufacturing segment profit, which includes the segment profits of our Truck, Engine, and Parts reporting segments, provides meaningful information of our core manufacturing business and therefore we use it to supplement our GAAP reporting by identifying items that may not be related to the core manufacturing business. 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 reconciliation, and to provide an additional measure of performance.

In addition, we believe that adjusted income and adjusted diluted earnings per share attributable to Navistar International Corporation and manufacturing segment profit excluding certain items, which are not considered to be part of our ongoing business, improves the comparability of year to year results and is representative of our underlying performance. 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 reconciliations below, and to provide an additional measure of performance.

Adjustments included in the following schedules have not been adjusted to reflect their income tax effect as the adjustments are intended to represent the impact on the company’s consolidated statement of operations without the incremental income tax effect that would result from the release of the income tax valuation allowance. The charges related to our Canadian operations would not be impacted as a full income tax valuation allowance remains for Canada.

(A) Engineering integration costs relate to the consolidation of our truck and engine engineering operations as well as the move of our world headquarters. These costs include restructuring charges for activities at our Fort Wayne facility of $6 million and $29 million for the three months and year ended October 31, 2011, respectively. We also incurred an additional $17 million and $35 million of other related costs for the three months and year ended October 31, 2011, respectively. Our manufacturing segment recognized $18 million and $51 million of the engineering integration costs for the three months and year ended October 31, 2011, respectively. The Truck segment recognized $49 million of the engineering integration costs for the year ended October, 31, 2011.

(B) Restructuring of North American manufacturing operations are charges primarily related to our plans to close our Chatham, Ontario heavy truck plant and Workhorse chassis plant in Union City, Indiana, and to significantly scale back operations at our Monaco recreational vehicle headquarters and motor coach manufacturing plant in Coburg, Oregon. These costs include restructuring charges of $5 million and $58 million for the three months and year ended October 31, 2011. We also incurred an additional $5 million of other related costs for the year ended October 31, 2011. In addition, the company recognized $64 million of impairment charges related to certain intangible assets and property plant and equipment primarily related to these facilities. The Truck segment recognized $5 million and $124 million of restructuring of North American manufacturing operation charges for the three months and year ended October 31, 2011.

(C) In the fourth quarter of 2011, the company had an unfavorable ruling related to a 2010 administrative change the company made to the prescription drug program under the OPEB plan affecting plan participants who are Medicare eligible. As a result the company recognized approximately $15 million of expense for postretirement benefits.

(D) In the third quarter of 2011, we recognized an income tax benefit of $1.476 billion from the release of a portion of our income tax valuation allowance. In the fourth quarter of 2011, we recognized an additional income tax benefit of $61 million related to the release of a portion of our income tax valuation allowance. As domestic earnings are now taxable with the release of the income tax valuation allowance we recognized $10 million of domestic income tax expense for 2011 that would not have been recognized had we not released a portion of the allowance. The $10 million of domestic income taxes were netted against the total benefit of $1.537 billion from the release of a portion of the income tax valuation allowance.

(E) Starting with the first quarter of 2011, the company changed its method of accruing for certain incentive compensation, specifically relating to cash bonuses, for interim reporting purposes from a ratable method to a performance-based method. This change did not have an impact on our annual financial results. We have revised our previously reported Quarterly Condensed Consolidated Statements of Operations and Financial Data on a retrospective basis to reflect this change in principle based on information that would have been available as of our previous filing.
