OSHKOSH CORPORATION REPORTS RESULTS FOR
FISCAL 2010 THIRD QUARTER

Reports Third Quarter EPS of $2.31 Compared to
Prior Year Loss of $0.28

Revenue Increases 100.8 Percent to $2.44 Billion

Reduced Long-Term Debt by $175 Million

OSHKOSH, WI — (August 2, 2010) — Oshkosh Corporation (NYSE: OSK), a leading manufacturer of specialty vehicles and vehicle bodies, today reported fiscal 2010 third quarter net sales of $2.44 billion and net income of $211.2 million, or $2.31 per share.  This compares with net sales of $1.22 billion and a loss from continuing operations of $21.2 million, or $0.28 per share, in the prior year third quarter.

“Our dedicated and committed employees worked hard to deliver third quarter records for revenue, operating income and EPS, led once again by strong performance in our defense segment,” said Robert G. Bohn, Oshkosh Corporation chairman and chief executive officer.  “We further improved our balance sheet during the quarter with debt reduction of $175 million.  Over the past two years we have retired $1.5 billion of debt as a result of strong free cash flow and $358 million of proceeds from a stock offering.  Debt reduction will remain the primary use for free cash flow by Oshkosh for the near term.

“This quarter, we commenced low rate production of access equipment in our newly constructed Tianjin, China facility.  We expect to gradually ramp up production in this facility over the next 12 months to serve Asian markets as access equipment becomes accepted as a productivity and safety tool for construction and industrial markets in this region.

“As we enter the fourth quarter of fiscal 2010, we expect another strong quarterly performance to close what we expect will be a stellar year for Oshkosh in terms of sales and earnings.  Looking forward to fiscal 2011, we expect that our defense segment performance will provide a solid foundation to what we anticipate will be a gradual economic recovery, although we will not attain defense segment revenue levels that approach our fiscal 2010 defense

performance because we will have completed the bulk of our M-ATV shipments in fiscal 2010.  We believe that our non-defense businesses will generally achieve higher revenues in fiscal 2011, as the economy improves.  Fiscal 2011 will also be a year in which we continue our focus on improving both our operations and our customers’ experiences with our Company,” commented Bohn.

The Company reported that consolidated net sales in the third quarter of fiscal 2010 doubled compared with the prior year third quarter largely due to $1.08 billion of sales under the M-ATV contract, including related aftermarket parts & service sales. In addition, the Company’s access equipment segment sales to external customers increased $162.7 million, or 77.0 percent, from very low sales levels in the prior year quarter.

Operating income increased to $340.5 million, or 14.0 percent of sales, for the third quarter of fiscal 2010 compared with operating income of $39.3 million, or 3.2 percent of sales, in the prior year third quarter.  Significantly improved defense segment performance, combined with improved access equipment segment performance, led to the increase in operating income.  Both the defense and access equipment segments benefited from significant M-ATV production during the quarter.  In addition, the access equipment segment achieved a small operating profit on sales to external customers in the third quarter of fiscal 2010 as compared with a $71.2 million loss in the prior year quarter.

Factors affecting third quarter results for the Company’s business segments included:

Defense — Defense segment sales increased $1.1 billion, or 180.9 percent, to $1.7 billion for the third quarter of fiscal 2010 compared with the prior year third quarter.  The increase in sales compared to the prior year quarter was due to the sale of 1,574 M-ATVs and related aftermarket parts & service under a contract that began in the fourth quarter of fiscal 2009.  Combined vehicle and parts & service sales related to the M-ATV program totaled approximately $1.08 billion in the third quarter of fiscal 2010.

Operating income in the third quarter for the defense segment more than tripled to $304.1 million, or 17.9 percent of sales, compared with prior year third quarter operating income of $92.9 million, or 15.3 percent of sales.  The increase in operating income as a percent of sales reflected a combination of high M-ATV related volume and relatively fixed engineering and administrative expenses compared to higher sales.

Access Equipment — Access equipment segment sales to external customers increased 77.0 percent to $373.9 million for the third quarter of fiscal 2010 compared with the prior year third quarter.  The access equipment segment experienced increases in sales in all major markets, with the largest dollar increases in North America and Latin America.  While North American sales remain significantly lower than historical levels due to weak construction markets and tight credit, sales have begun to recover from historic lows.  Third quarter fiscal 2010 access equipment segment sales also included $316.0 million of intersegment M-ATV related sales to the defense segment as the Company continued to leverage underutilized facilities in the access equipment segment to meet defense production requirements.  In total, segment sales increased 226.6 percent to $689.9 million for the third quarter of fiscal 2010 compared with the prior year quarter.

The access equipment segment reported operating income of $31.6 million, or 4.6 percent of sales, for the third quarter of fiscal 2010 compared with an operating loss of $71.2 million, or 33.7 percent of sales, in the prior year quarter.  Operating results benefited from lower allowances for credit losses, intersegment M-ATV sales at high single-digit margins, higher volume of sales to external customers and lower material costs.

Fire & Emergency — Fire & emergency segment sales for the third quarter of fiscal 2010 decreased 15.6 percent to $243.3 million compared with the prior year quarter.  The decrease in sales reflected lower shipments for most businesses in the segment due to softer demand attributed to declining municipal budgets in the U.S. and overall economic weakness combined with the timing of shipments in airport products.

Operating income decreased 46.6 percent in the third quarter of fiscal 2010 to $17.5 million, or 7.2 percent of sales, compared with the prior year quarter operating income of $32.7 million, or 11.4 percent of sales.  The decrease in operating income during the third quarter was primarily the result of the lower volume and an adverse product mix.

Commercial — Commercial segment sales increased 14.4 percent to $158.3 million in the third quarter of fiscal 2010 compared with the prior year quarter.  The increase in sales was due to a 45.8 percent increase in concrete placement products sales, off a low base, due to sales growth internationally and a slight increase in domestic demand as well as increased intersegment production of heavy tactical vehicle components for the defense segment.

Operating income increased to $7.0 million in the third quarter of fiscal 2010, or 4.4 percent of sales, compared with operating income of $2.1 million, or 1.5 percent of sales, in the prior year quarter.  The increase in operating income primarily resulted from the profit on intersegment manufacturing activities.

Corporate — Corporate operating expenses increased $6.3 million to $23.3 million for the third quarter of fiscal 2010 compared with the prior year quarter.  The increase was the result of higher incentive compensation, including higher share-based compensation expense.

Intersegment Eliminations — Income from the reversal of intersegment profit eliminations on sales between segments (largely M-ATV related sales between access equipment and defense) was $3.6 million in the third quarter of fiscal 2010.  The eliminated profit is recognized as income once the related inventory is sold to an external customer.

Interest Expense Net of Interest Income — Interest expense net of interest income decreased $21.9 million to $41.0 million in the third quarter of fiscal 2010 compared with the prior year quarter largely due to the effects of lower borrowings as average debt outstanding decreased from $2.5 billion during the third quarter of fiscal 2009 to $1.5 billion during the third quarter of fiscal 2010.  In addition to debt reduction as a result of strong cash flow generation during the past 12 months, the Company completed a common stock offering early in the fourth quarter of fiscal 2009, which provided $358 million of net cash proceeds that the Company applied to reduce outstanding debt.

Provision for Income Taxes — The Company recorded income tax expense of $87.4 million in the third quarter of fiscal 2010, or 29.3 percent of pre-tax income from continuing operations.  The current year quarter effective tax rate benefited from a $15.3 million, or 513 basis points, favorable income tax audit settlement.

Discontinued Operations

In July 2009, the Company sold its ownership in Geesink Group B.V., Geesink Norba Limited and Norba A. B. (collectively, the Geesink Norba Group). The Geesink Norba Group, the Company’s former European refuse collection vehicle manufacturer, was included in the Company’s commercial segment.  In October 2009, the Company sold its 75 percent ownership in BAI Brescia Antincendi International S.r.l. (BAI).  BAI, the Company’s former European fire apparatus manufacturer, was included in the Company’s fire & emergency segment.  The historical results of operations of these businesses have been presented as discontinued operations, net of tax, in the Condensed Consolidated Statements of Operations for all periods.

Nine-month Results

Excluding impairment charges(1), the Company reported earnings from continuing operations of $7.65 per share for the first nine months of fiscal 2010 on sales of $7.74 billion and income from continuing operations of $695.0 million, compared with a loss of $0.64 per share for the first nine months of fiscal 2009 on sales of $3.78 billion and a loss from continuing operations of $47.4 million.  Including impairment charges, the Company reported earnings from continuing operations of $7.44 per share on income from continuing operations of $676.3 million for the first nine months of fiscal 2010 as compared to a loss from continuing operations of $1.21 billion, or $16.30 per share, for the first nine months of the prior year.  The increase in sales and income from continuing operations was primarily due to sales of M-ATV units and related aftermarket parts & service.  Combined vehicle and parts & service sales under the M-ATV program, which had initial shipments in the fourth quarter of fiscal 2009, totaled approximately $3.81 billion in the first nine months of fiscal 2010.
