OSHKOSH CORPORATION REPORTS RECORD RESULTS FOR FISCAL 2010 SECOND QUARTER

Reports Second Quarter EPS of $3.22 Compared to
Prior Year Loss, Excluding Impairment Charges, of $0.20(1)

Revenue Increases 131.5 Percent to $2.86 Billion

Reduced Long-Term Debt by $239 Million

OSHKOSH, WI — (April 29, 2010) — Oshkosh Corporation (NYSE: OSK), a leading manufacturer of specialty vehicles and vehicle bodies, today reported fiscal 2010 second quarter net sales of $2.86 billion and net income of $292.6 million, or $3.22 per share.  This compares with net sales of $1.24 billion and a loss from continuing operations of $0.20 per share, excluding non-cash intangible asset impairment charges related to goodwill and other long-lived assets in the prior year second quarter.  Including pre-tax, non-cash impairment charges of $1.19 billion ($15.66 per share, net of taxes), the Company reported a loss from continuing operations of $1.18 billion, or $15.86 per share, for the second quarter of the prior year.

“We delivered record results in the second quarter of fiscal 2010 as our defense segment performed exceptionally well driven by continued strong deliveries of M-ATVs for our warfighters in Afghanistan,” said Robert G. Bohn, Oshkosh Corporation chairman and chief executive officer.  “During the quarter, we also received notice that our contract award to supply the U.S. Army with its requirements for the Family of Medium Tactical Vehicles was upheld.  Despite delays caused by the protest of the award, we expect to start production for the program according to the original contract schedule later this calendar year.

“We continued to improve our balance sheet during the quarter by paying down $239 million of debt and extending out our debt maturities by completing the issuance of $500 million

of senior notes that mature in 2017 and 2020.  We used the net proceeds of $489.2 million from the senior notes to repay debt that was scheduled to mature in December 2013.

“We expect fiscal 2010 to be a record year for Oshkosh in terms of sales and earnings, driven by strength in our defense segment while most of our non-defense businesses continue to face soft markets.  We continue to invest in lean initiatives to mitigate the effects of the soft markets and streamline operations for fiscal 2011 when we believe these markets will be stronger,” added Bohn.

The Company reported that consolidated net sales in the second quarter of fiscal 2010 more than doubled compared with the prior year second quarter largely due to $1.63 billion of sales under the M-ATV contract, including related aftermarket parts & service sales.

Operating income increased to $494.3 million, or 17.3 percent of sales, for the second quarter of fiscal 2010 compared with operating income, excluding impairment charges(1), of $25.6 million, or 2.1 percent of sales, in the prior year second 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 high volume M-ATV production.  In addition, the access equipment segment benefited from improved results in its base business in the second quarter of fiscal 2010 as compared with the prior year quarter.  Including impairment charges, the Company reported an operating loss of $1.16 billion in the prior year second quarter.

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

Defense — Defense segment sales increased $1.68 billion, or 284.6 percent, to $2.27 billion for the second quarter of fiscal 2010 compared with the prior year second quarter.  The increase in sales compared to the prior year quarter was due to the high rate production of M-ATV units 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 $1.63 billion in the second quarter of fiscal 2010.

Operating income in the second quarter increased more than 500 percent to $452.8 million, or 19.9 percent of sales, compared with prior year second quarter operating income of $75.0 million, or 12.7 percent of sales.  The increase in operating income as a percent of sales reflected a combination of higher M-ATV related volume, lower material costs and an improved parts & service mix.

Access Equipment — Access equipment segment sales to external customers increased 1.5 percent to $252.9 million for the second quarter of fiscal 2010 compared with the prior year second quarter.  The slight increase was primarily related to fluctuations in foreign currency exchange rates as relatively strong demand in South America and the Pacific Rim, including Australia, was more than offset by continued weakness in North America and Europe, Africa and the Middle East due to weak construction markets and tight credit.  Second quarter fiscal 2010 access equipment segment sales also included $737.2 million of intersegment M-ATV related sales to the defense segment as the Company continued to leverage underutilized facilities in the access equipment segment and call back idled employees to meet defense production requirements.  In total, segment sales increased 297.3 percent to $990.1 million for the second quarter of fiscal 2010 compared with the prior year quarter.

The access equipment segment reported operating income of $46.1 million, or 4.7 percent of sales, for the second quarter of fiscal 2010 compared with an operating loss, excluding impairment charges(1), of $49.1 million, or 19.7 percent of sales, in the prior year quarter.  Operating results benefited from the recognition of intersegment M-ATV sales at high single-digit margins.  Operating results for the access equipment segment also benefited from lower material costs, fewer customer trade-ins and favorable foreign currency exchange rates.

Fire & Emergency — Fire & emergency segment sales for the second quarter of fiscal 2010 decreased 17.2 percent to $234.2 million compared with the prior year quarter.  The decrease in sales reflected lower shipments across most of the segment, due to softer demand attributable to declining municipal budgets in the U.S., a weak U.S. economy and continued weak demand for mobile medical equipment in an uncertain health care environment.

Operating income decreased 24.7 percent in the second quarter of fiscal 2010 to $19.0 million, or 8.1 percent of sales, compared with the prior year quarter operating income, excluding impairment charges(1), of $25.3 million, or 9.0 percent of sales.  The decrease in operating income during the second quarter was primarily the result of the lower volume.  Including impairment charges, the fire & emergency segment reported an operating loss of $86.1 million in the second quarter of the prior year.

Commercial — Commercial segment sales increased 3.7 percent to $145.9 million in the second quarter of fiscal 2010 compared with the prior year quarter.  The increase in sales was due to increased intersegment production of heavy tactical vehicle components for the defense segment.  An increase in sales of concrete placement products of 14 percent as compared to the prior year quarter as a result of international growth was offset by an almost 10 percent decrease in domestic refuse collection vehicle (RCV) sales.  The prior year second quarter RCV sales benefited from the timing of deliveries to large waste haulers.

Operating income increased to $1.4 million in the second quarter of fiscal 2010, or 1.0 percent of sales, compared with an operating loss, excluding impairment charges(1), of $5.9 million, or 4.3 percent of sales, in the prior year quarter.  The increase in operating results primarily resulted from the profit on intersegment manufacturing activities and the benefits of cost reductions implemented in fiscal 2009.

Corporate — Corporate operating expenses increased $3.9 million to $23.8 million for the second 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 — Intersegment eliminations of $1.2 million in the quarter resulted from profit on intersegment sales between segments (largely M-ATV related sales between access equipment and defense) where the related inventory sold from one segment to another has not yet been sold to a third party customer.

Interest Expense Net of Interest Income — Interest expense net of interest income increased $4.5 million to $45.2 million in the second quarter of fiscal 2010 compared with the prior year quarter as the Company expensed deferred financing expenses of $5.3 million associated with the prepayment of debt.  Higher interest rates associated with the March 2009 amendment of the Company’s credit agreement were more than offset by the effects of lower borrowings as average debt outstanding decreased from $2.61 billion during the second quarter of fiscal 2009 to $1.74 billion during the second quarter of fiscal 2010.  In addition to debt reduction as a result of strong cash flow generation during the past twelve months, the Company completed a common stock offering early in the fourth quarter of fiscal 2009, which provided $358 million of net proceeds that the Company applied to reduce outstanding debt.

Provision for Income Taxes — The Company recorded income tax expense of $157.4 million in the second quarter of fiscal 2010, or 35.0 percent of pre-tax income from continuing operations.  Excluding the impact of the largely non-deductible impairment charges, the Company recorded a tax benefit in the second quarter of fiscal 2009 of $3.8 million on a pre-tax loss of $14.5 million.  The tax benefit was lower than the statutory rate as tax expense was impacted by a $5.8 million reversal of a portion of a European tax incentive.

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 RCV 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.

Six-month Results

Excluding impairment charges(1), the Company reported earnings from continuing operations of $5.33 per share for the first six months of fiscal 2010 on sales of $5.30 billion and income from continuing operations of $483.8 million, compared with a loss of $0.36 per share for the first six months of fiscal 2009 on sales of $2.57 billion and a loss from continuing operations of $26.3 million.  Including impairment charges, the Company reported earnings from continuing operations of $5.12 per share on income from continuing operations of $465.1 million for the first six months of fiscal 2010 as compared to a loss from continuing operations of $1.19 billion, or $16.02 per share, for the first six months of the prior year.  The increase in sales and income from continuing operations were primarily due to sales of M-ATV units and related aftermarket parts & service.  Combined vehicle and parts & service sales related to the M-ATV program totaled approximately $2.74 billion in the first six months of fiscal 2010.

Non-GAAP Financial Measures

The Company reports its financial results in accordance with generally accepted accounting principles (GAAP) in the United States of America.  The Company is presenting various operating results, such as operating income (loss), income (loss) from continuing operations and earnings (loss) per share from continuing operations on both a reported basis and on a basis excluding impairment charges that affect comparability of operating results.  When the Company uses operating results, such as operating income (loss), income (loss) from continuing operations and earnings (loss) per share from continuing operations, excluding impairment charges, they are considered non-GAAP financial measures.  The Company believes excluding the impact of non-cash intangible asset impairment charges is useful to investors to allow a more accurate comparison of the Company’s operating performance.  Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, the Company’s results prepared in accordance with GAAP.  The table below presents a reconciliation of the Company’s presented non-GAAP measures to the most directly comparable GAAP measures for the three and six months ended March 31 (in millions, except per share amounts):
