Management Comments:
“The fiscal quarter-ended July 31, 2017 was a positive beginning to fiscal year 2018.  Revenue increased 2% to $11.6 million in the three months ended July 31, 2017, as compared to $11.4 million in the three months ended July 31, 2016.  The increase in revenue reflects an increase in Aerospace Products revenue (up 8%) and a decrease of 1% in Professional Services revenue.  Butler National Corporation continues to drive growth in international markets and through the development of new supplemental type certificates.  This includes significant efforts in South America, Europe, Africa, and Asia.

First quarter fiscal 2018 resulted in a net income of $238,000 compared to a net income of $224,000 in the first quarter fiscal 2017.  Butler National Corporation is working to exceed previous revenue levels while continuing to focus on our margin expansion initiatives, including efficiencies in our implementation and operational processes and controlling expenses.

During the three months ending July 31, 2017, we invested approximately $398,000 in projects focused on the development and acquisition of new products.  We feel this expenditure for design and development engineering, testing, and certification of new products is required to grow Aerospace Products and help stabilize our long-term revenue and enhance our profits.

We are excited about the future.  Management and all employees are focused on the development of new products, execution of our numerous business development opportunities as well as increasing revenue while managing costs. We believe we are positioned for the future as we focus on serving the needs of our customers and enhancing shareholder value,” commented Clark D. Stewart, President of the Company.
