Management Comments:

"Fiscal 2007 was our second best year ever for profits after tax, $606,000, and our third best year ever for sales, $14,681,000. Sales for fiscal 2007 decreased $626,000 (4.1%) from fiscal 2006. Net income for fiscal 2007 increased $240,000, (65.6%) from fiscal 2006. We consider 2007 another successful year for Butler National. We continue our efforts to improve the profitability in the delivery of high-value "Classic Aviation" products.

We expensed $1,946,000, 13% of our sales, on product development. We feel this expenditure for the design and development engineering, testing, and certification of new products may stabilize our long-term revenues and enhance our profits.

Fiscal 2007 Avionics sales were $3,538,000, an increase of $644,000 (22.2%) from fiscal 2006. This increase is directly related to sales of defense products. Fiscal 2007 Avionics operating profits were $287,000, a decrease of $6,000 (2.0%) from fiscal 2006. This decrease is related to additional costs for materials, material spoilages, labor requirements, and rework labor associated with a major lower margin "build-to-print" contract. Further additional costs from this contract may be experienced on this contract in fiscal 2008. We expect that some of the TSD products currently in service will be returned for inspection and recertification during fiscal 2008 and 2009.

Fiscal 2007 sales for Aircraft Modifications were $6,697,000, a decrease of $884,000 (11.7%) from fiscal 2006. Fiscal 2007 RVSM sales decreased $553,000 and modification service sales decreased $331,000 from fiscal 2006. After considering the lower sales, fiscal 2007 operating loss for Aircraft Modifications was $227,000, an improvement of $76,000 (25.1%) from fiscal 2006. Sales and profits may have been more improved for fiscal 2007 if some of the orders in excess of $300,000 could have been delivered by the fiscal year end. These will be reflected in the first quarter of FY 2008.
