WINNEBAGO INDUSTRIES TO RESTATE SECOND QUARTER AND YEAR-TO-DATE
FISCAL 2005 RESULTS

FOREST CITY, IOWA, May 17, 2005 — Winnebago Industries, Inc. (NYSE: WGO) today announced that it will restate its second quarter and year-to-date results for the periods ended February 26, 2005.
        During an internal review of the Company’s annual physical inventory, an error was found in a formula of an electronic spreadsheet. The error resulted in an overstatement of inventory and an understatement of cost of sales of $2,793,000. The restatement, net of income tax effect, will result in a reduction of net income during the 13 and 26 weeks ended February 26, 2005 of $1,795,000 or $.05 per diluted share.
        As a result, the Company’s previously issued financial statements for the 13 and 26 weeks ended February 26, 2005 should no longer be relied upon. Attached hereto are the Company’s unaudited consolidated balance sheet as of February 26, 2005, the Company’s unaudited consolidated statements of income for the 13 and 26 weeks ended February 26, 2005 and the Company’s unaudited condensed consolidated statement of cash flows for the 26 weeks ended February 26, 2005, reflecting (i) balances as reflected in the previously filed Form 10-Q for the quarter ended February 26, 2005, (ii) adjustments to reflect the overstatement of inventory valuation and understatement of cost of sales and (iii) balances as restated to the overstatement of inventory valuation and understatement of cost of sales. The restatements will not have any impact on the Company’s cash position at February 26, 2005 or its revenues for the periods affected.
        The Company intends to file a Form 10-Q/A for the quarter ended February 26, 2005 which will include restated consolidated financial statements as soon as practicable.
