Towable RV sales in the nine months were $1,090,842,000, up 64% from $664,517,000 last year. Motorized RV sales in the nine months were $194,049,000, up 73% from $112,499,000 last year.

Bus segment sales in the nine months were a record $327,878,000, up 8% from $303,956,000 last year.

“These results are in excess of analyst consensus estimates, which were raised during the quarter,” said Peter B. Orthwein, Thor chairman. “Thor’s improved margins demonstrate the effect of our aggressive cost-cutting efforts, leading to better opportunity going forward. Thor is encouraged by the RV industry’s recovery, including our internal retail results through May, 2010. We continue to have a strong cash position and zero debt, which will help fuel additional growth in the future,” he added.

The Company will file a Form 12b-25 (Notification of Late Filing and Application for Extension to File) with the Securities and Exchange Commission with respect to its Quarterly Report on Form 10-Q for the period ended April 30, 2010 (the “Company’s 10-Q”). The extension is required because the Company’s independent auditor, Deloitte & Touche LLP (“Deloitte”), has not yet completed its review of the interim financial statements to be included in the Company’s 10-Q due to their evaluation of certain accounting positions previously taken by the Company in its audited financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended July 31, 2009 (the “Company’s 10-K”) and the unaudited financial statements included in the Company’s Quarterly Reports on Form 10-Q for the periods ended January 31, 2009, April 30, 2009, October 31, 2009 and January 31, 2010.

In this regard, Deloitte is addressing issues relating to the accounting treatment for (a) the Company’s transactions with Stephen Adams and FreedomRoads that were consummated in January 2009, and (b) repurchase reserves relating to agreements with lenders to the Company’s independent dealers and revenue recognition issues with respect to transactions with its independent dealers. The Company’s accounting treatment for these matters is described in the Company’s 10-K. The Company continues to work with Deloitte to address these matters. If the Company is required to change its accounting for these items, there could be material adverse changes to the Company’s results of operations and financial condition for fiscal 2009 and for the first three quarters of fiscal 2010.

Thor is the world’s largest manufacturer of recreation vehicles and a major builder of commercial buses & ambulances.
