OSHKOSH TRUCK REPORTS THIRD QUARTER EPS UP 23.5%; RAISES
FULL-YEAR OUTLOOK TO $4.30 AND ANNOUNCES FISCAL 2006 EPS
EXPECTED RANGE OF $4.80 TO $5.00

        OSHKOSH, WIS. (August 2, 2005) – Oshkosh Truck Corporation (NYSE: OSK), a leading manufacturer of specialty trucks and truck bodies, today reported that for the quarter ended June 30, 2005, earnings per share increased 23.5 percent to $1.05 per share, on sales of $818.9 million and net income of $38.7 million. The results included a $4.3 million ($3.0 million after-tax), or $0.08 per share, charge for workforce reductions at the Company’s European refuse business. This compares with earnings per share of $0.85 on sales of $599.8 million and net income of $30.6 million for last year’s third quarter. These results exceeded Oshkosh’s most recent sales and earnings estimates for the third quarter of fiscal 2005 of $794.0 million and $1.03 per share, respectively. Oshkosh also increased its sales and earnings per share estimates for the full year ending September 30, 2005 to $2.96 billion and $4.30 per share, respectively. All per share amounts included in this release are reported on a pre-split basis with respect to a two-for-one split of the Company’s common stock as separately announced today.

        Sales increased 36.5 percent in the third quarter. Operating income increased 28.1 percent to $63.0 million, or 7.7 percent of sales, compared to $49.2 million, or 8.2 percent of sales, in the prior year’s third quarter. Operating results for the quarters ended June 30, 2005 and 2004 included charges for workforce reductions and life-to-date adjustments to the margins on the Medium Tactical Vehicle Replacement (“MTVR”) base contract in each period as described below.

        Commenting on the results, Robert G. Bohn, Oshkosh chairman, president and chief executive officer, said, “I am pleased with the exceptional financial performance provided by our defense and fire and emergency businesses, which contributed to record third quarter earnings. Defense parts and truck revenue growth were significant factors in our quarterly performance, and the outlook for future business remains positive. And, our fire and emergency business increased both revenues and earnings sharply from both acquisitions and significant organic growth.

        “In our commercial business, we are aggressively pursuing improvement and anticipate this will yield positive results for this segment beginning in fiscal 2006. Commercial results are being positively influenced by “lean” initiatives. In the U.S., this has yielded record deliveries, improved lead times for our customers, and inventory reductions, each of which are underlying indicators of performance improvement. To restore profitability to our European refuse business, we regret that these initiatives will mean a reduction of the workforce in The Netherlands. In addition, steel costs have stabilized, which should be a factor in recovering margins.

        “Oshkosh Truck is focused on growth, as we ramp up defense remanufacturing, expand our fire apparatus manufacturing capacity, and target better results in our commercial segment. In addition, we believe our markets continue to exhibit the fundamentals necessary for future growth, and we today announce our earnings per share estimated range for fiscal 2006 of $4.80 to $5.00, up 11.6 percent to 16.3 percent from our current full year fiscal 2005 estimates.”

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

        Fire and emergency—Fire and emergency segment sales increased 56.2 percent, to $222.7 million for the quarter compared to the prior year. Operating income was up 75.4 percent to $23.1 million, or 10.4 percent of sales, compared to prior year operating income of $13.2 million, or 9.2 percent of sales. The JerrDan and BAI acquisitions contributed sales of $42.0 million and operating income of $4.1 million during the quarter. Sales and operating income from other businesses in this segment grew 26.7 percent and 44.0 percent, respectively, for the quarter. The higher sales level for these businesses reflected strong order flow for fire apparatus and substantially higher airport product sales. Operating income margins for the businesses increased due to a substantially improved sales mix of custom pumpers, aerials and airport products.

        Defense—Defense segment sales increased 47.1 percent to $281.0 million for the quarter compared to the prior year’s third quarter due to a near doubling of parts and service sales as a result of the conflict in Iraq and substantially higher truck sales. Operating income in the third quarter was up 35.4 percent, to $46.0 million, or 16.4 percent of sales, compared to prior year operating income of $33.9 million, or 17.8 percent of sales. Third quarter earnings were favorably impacted by the increase in relatively higher-margin parts and service sales and higher truck sales which were offset in part by substantially higher new product development spending. Third quarter earnings reflected a $2.1 million life-to-date adjustment to operating income to increase margins on the Company’s MTVR base contract from 9.9 percent to 10.1 percent. The Company had reported a life-to-date adjustment to MTVR base contract margins during the third quarter of fiscal 2004 of $7.1 million to raise its margins to a 7.1 percent rate at that time.

-Continued-

        Commercial—Commercial segment sales increased 18.5 percent, to $322.3 million, for the quarter on strong order intake in U.S. markets. Operating income decreased 46.0 percent to $7.2 million, or 2.2 percent of sales, compared to $13.4 million, or 4.9 percent of sales, in the prior year quarter. The CON-E-CO and London acquisitions contributed sales of $20.0 million and operating income of $1.5 million during the quarter. The decrease in operating income margins from the prior year was a result of the $4.3 million (1.3 percent of sales) charge for workforce reductions at the Company’s European refuse business, continued operating losses in the Company’s European refuse business and price increases for concrete placement and domestic refuse products that were not high enough to recover higher steel and component costs. Results for the third quarter of fiscal 2004 included a $1.8 million (0.7 percent of sales) charge for workforce reductions at the Company’s European refuse business.

        Corporate and other—Operating expenses and inter-segment profit elimination increased $2.0 million to $13.3 million, due largely to increased personnel costs. Net interest expense in the third quarter increased $0.4 million to $1.4 million, compared to the prior year quarter. Higher interest costs were largely due to higher average borrowings as a result of acquisitions.

        Total debt decreased during the quarter to $23.6 million at June 30, 2005 from $69.4 million at March 31, 2005 and cash increased to $43.1 million at June 30, 2005 from $23.2 million at March 31, 2005 due to strong cash flow from operations.

Nine-Month Results

        The Company reported that earnings per share increased 39.1 percent to $3.20 per share for the first nine months of fiscal 2005 on sales of $2,136.2 million and net income of $117.5 million compared to $2.30 per share for the first nine months of fiscal 2004 on sales of $1,611.2 million and net income of $82.8 million. Results for the first nine months of fiscal 2005 included MTVR base contract life-to-date margin adjustments totaling $24.7 million and a favorable product liability settlement totaling $4.2 million that increased operating income for the period and a charge for workforce reductions of $4.3 million. Results for the first nine months of fiscal 2004 include MTVR base contract life-to-date margin adjustments totaling $14.2 million that increased operating income for the period and a $1.8 million charge for workforce reductions.

        Operating income increased 47.5 percent to $193.2 million, or 9.0 percent of sales, in the first nine months of fiscal 2005 compared to $131.0 million, or 8.1 percent of sales, in the first nine months of fiscal 2004.

Forward-Looking Statements

        This press release contains statements that the Company believes are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact, including statements regarding the Company’s future financial position, business strategy, targets, projected sales, costs, earnings, capital spending and debt levels, and plans and objectives of management for future operations, are forward-looking statements. When used in this press release, words such as the Company “expects,” “intends,” “estimates,” “anticipates,” or “believes” and similar expressions are generally intended to identify forward-looking statements. These forward-looking statements are not guarantees of future performance and are subject to risks, uncertainties, assumptions and other factors, some of which are beyond the Company’s control, that could cause actual results to differ materially from those expressed or implied by such forward-looking statements. These factors include, without limitation, the Company’s ability to turnaround its Geesink Norba Group and McNeilus businesses, the cyclical nature of the Company’s commercial and fire and emergency markets, risks related to reductions in government expenditures, the uncertainty of government contracts, the challenges of identifying acquisition candidates and integrating acquired businesses, rapidly rising steel and component costs and the Company’s ability to avoid such cost increases based on its supply contracts or recover such rising costs with increases in selling prices of its products, the success of the launch of the Revolution^® composite concrete mixer drum, and risks associated with international operations and sales, including foreign currency fluctuations. In addition, the Company’s expectations for fiscal 2005 and 2006 are based in part on certain assumptions made by the Company, including, without limitation, those relating to the Company’s ability to turnaround the business of the Geesink Norba Group sufficiently to support its current valuation resulting in no non-cash impairment charge for Geesink Norba Group goodwill; the Company’s ability to increase its operating income margins at McNeilus; the ability of the Company to recover steel and component cost increases from its customers; increasing concrete placement activity; the performance of the U.S. and European economies generally; when the Company will receive sales orders and payments; achieving cost reductions; production and margin levels under the Family of Heavy Tactical Vehicles contract, the Indefinite Demand/Indefinite Quantity contract, the MTVR follow-on contract and for international defense trucks; the level of U.S. Department of Defense procurement of replacement parts, services and remanufacturing of trucks; targets for Geesink Norba Group sales and operating losses; capital expenditures of municipalities, airports and large waste haulers; the availability of commercial chassis and certain chassis components; spending on bid and proposal activities and new product development; interest and personnel costs; the ability to integrate acquired businesses; and that the Company does not complete any acquisitions. Additional information concerning these and other factors is contained in the Company’s filings with the Securities and Exchange Commission, including the Form 8-K filed today.
