NAVISTAR REPORTS FIRST QUARTER RESULTS

• Navistar reports net loss of $248 million on revenues of $2.2 billion

• Ends quarter with $1.1 billion in manufacturing cash, at high end of guidance

• EBITDA better than guidance, excluding one-time items and pre-existing warranty

• Finishes Q1 with 56 percent backlog increase year-over-year

• Delivers $67 million in additional structural cost savings

LISLE, Ill. (March 5, 2014) – Navistar International Corporation (NYSE: NAV) today announced a first quarter 2014 net loss of $248 million, or $3.05 per diluted share, compared to a first quarter 2013 net loss of $123 million, or $1.53 per diluted share. Revenues in the quarter were $2.2 billion, down from $2.6 billion in the first quarter of 2013. Lower sales volumes, primarily due to the company’s medium-duty emissions strategy transition and lower military sales, drove the year-over-year performance decline, which was partially offset by $67 million in reduced structural costs. First quarter 2014 results include an unfavorable impact of $21 million due to fluctuations in foreign exchange rates and $18 million in asset impairment charges.

“We signaled that this would be a tough quarter due to our mid-range product transition, the ongoing reduced sales in our military business, and because the first quarter, historically, represents the weakest operational period of the year for us. Given all this, we are encouraged we hit our cash and adjusted EBITDA guidance,” said Troy A. Clarke, Navistar’s president and chief executive officer. “Clearly, we have more hard work to do to rebuild our market share and further reduce our costs, but we continue to make progress on our Drive to Deliver, and we feel we’re off to a solid start in 2014.”

Navistar delivered at the high end of its first quarter manufacturing cash guidance range of $1.0 billion to $1.1 billion, ending the quarter with approximately $1.1 billion in manufacturing cash, cash equivalents and marketable securities. First quarter 2014 EBITDA was a loss of $110 million, which included $52 million in pre-existing warranty adjustments and a net $21 million in one-time items. Adjusted EBITDA was a loss of $37 million, which was better than the company’s first quarter guidance of a loss between $50 million to $100 million, excluding pre-existing warranty and one-time items.

First quarter product highlights included the successful launch of the Cummins ISB engine offering in the medium-duty International^® DuraStar^® and IC Bus^™ CE Series school bus. These and other actions helped the company achieve Class 6/7 retail share of 22 percent and Class 8 retail share of 18 percent in January. Both represented the highest monthly retail share performance Navistar has attained in the last six months, and helped offset lower than expected retail performance in the first two months of the quarter. The company finished the quarter with an order backlog 56 percent higher than this time one year ago.

Also during the quarter, Navistar swept the competition at this year’s American Truck Dealers Convention and Exposition in January. Selected based on a number of criteria, including innovation and design, safety and driver and owner satisfaction, the International ProStar^® with Cummins ISX15 engine and International TerraStar^® 4x4 were named “2014 Heavy-Duty Commercial Truck of the Year” and “2014 Medium-Duty Commercial Truck of the Year,” respectively.

Navistar continued engine restructuring efforts last month when it announced plans to consolidate mid-range engine manufacturing into its Melrose Park, Ill., engine plant. Once completed later this summer, these actions – which include idling the Huntsville, Ala., mid-range engine plant – are expected to reduce Navistar’s operating costs by more than $22 million annually.

As a next step in its engine business restructuring, the company is announcing it will add selective catalytic reduction (SCR) emissions technology to its high horsepower inline six-cylinder (I-6) engine platforms to complement the recent launch of the Cummins ISB. The company is already taking orders with deliveries scheduled for this summer.

“These actions will help us deliver on one of our biggest opportunities—reclaiming our market position in medium-duty and bus, which historically have been important businesses for us and our dealers,” Clarke said. “We’re gaining momentum in the marketplace. As we fully launch our mid-range SCR portfolio in the coming months and complete this phase of our engine restructuring, we anticipate we will improve our financial performance throughout 2014 and remain on path to achieving our guidance of an 8 to 10 percent EBITDA margin run rate exiting 2015.”

(A) Amounts attributable to Navistar International Corporation

North America Truck — For the first quarter 2014, the North America truck segment recorded a loss of $207 million, compared with a year-ago first quarter loss of $101 million. The year-over-year deterioration was driven by an 18 percent drop in net sales due to lower traditional truck volumes, primarily driven by the company’s mid-range emissions strategy transition and significantly lower demand for the company’s military products due to reduced spending in the tactical wheeled vehicles segment. Reduced SG&A expenses and engineering and product

development costs helped partially offset the impact of lower revenues. Additionally, the segment incurred asset impairment charges of $18 million related to the company’s ongoing evaluation of certain North American truck portfolio assets and $3 million of charges related to the idling of the Huntsville mid-range engine plant.

North America Parts — For the first quarter 2014, the North America parts segment recorded a profit of $104 million, compared with a year-ago first quarter profit of $117 million. The year-over-year decrease primarily was driven by lower military sales, which partially were offset by lower SG&A expenses resulting from the company’s ongoing cost-reduction initiatives.

Global Operations — For the first quarter 2014, global operations recorded a loss of $33 million, compared with a year-ago first quarter loss of $10 million. The year-over-year decline was driven by lower volumes in Navistar’s South America engine operations and unfavorable exchange rate fluctuations, primarily in the Brazilian Real, as well as lower export truck sales.

Financial Services — For the first quarter 2014, the financial services segment recorded a profit of $23 million, comparable to first quarter 2013 profit of $22 million. Financial Service’s debt-to-equity ratio stood at 2.4:1 at the end of the first quarter 2014.

SEC Regulation G Non-GAAP Reconciliation

The financial measures presented below 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 and are reconciled to the most appropriate GAAP number below.

Manufacturing Cash, Cash Equivalents, and Marketable Securities:

Manufacturing cash, cash equivalents, and marketable securities represents the Company’s consolidated cash, cash equivalents, and marketable securities excluding cash, cash equivalents, and marketable securities of our financial services operations. We include marketable securities with our cash and cash equivalents when assessing our liquidity position as our investments are highly liquid in nature. 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.

Earnings (loss) Before Interest, Income Taxes, Depreciation, and Amortization (“EBITDA”):

We define EBITDA as our consolidated net income (loss) from continuing operations attributable to Navistar International Corporation, net of tax, plus manufacturing interest expense, income taxes, and depreciation and amortization. We believe EBITDA provides meaningful information to the performance of our business and therefore we use it to supplement our GAAP reporting. 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.

Adjusted EBITDA:

We believe that adjusted EBITDA, which excludes certain identified items that we do not considered to be part of our ongoing business, improves the comparability of year to year results, and is representative of our underlying performance. Management 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.

Structural costs consists of Selling, general and administrative expenses and Engineering and product development costs.

Adjusted EBITDA	$	(37	)

(A) Adjustments to pre-existing warranties reflect changes in our estimate of warranty costs for products sold in prior periods. Such adjustments typically occur when claims experience deviates from historic and expected trends. Our warranty liability is generally affected by component failure rates, repair costs, and the timing of failures. Future events and circumstances related to these factors could materially change our estimates and require adjustments to our liability. In addition, new product launches require a greater use of judgment in developing estimates until historical experience becomes available.

(B) In the first quarter of 2014, the Company concluded it had a triggering event related to potential sales of assets requiring assessment of impairment for certain intangible and long-lived assets in the North America Truck segment. As a result, the North America Truck segment recognized asset impairment charges of $18 million.

The above items did not have a material impact on taxes due to the valuation allowances on our U.S. deferred tax assets, which was established in the fourth quarter of 2012.
