Management Comments:

"Fiscal 2017 was a successful year for Butler National Corporation. Revenue increased 13% to $50.6 million in fiscal 2017 from $44.8 million in fiscal 2016. Revenue from Professional Services increased 4% and revenue from Aerospace Products increased 32%. Butler National Corporation continues to focus on growth in international markets and through the development of new supplemental type certificates. This includes significant efforts in South America, Europe, Africa, and Asia.

Fiscal 2017 net income was $1.5 million compared to a net income of $24,000 in fiscal 2016. Fiscal 2017 operating margin was 7% compared to a 2% operating margin in fiscal 2016. We continue to work to improve efficiencies in our implementation, operational processes, and controlling general and administrative expenses.

The fourth quarter of fiscal 2017 was a positive quarter for Butler National Corporation. Revenue increased 27% to $15.1 million in fourth quarter fiscal 2017, as compared to $11.9 million in fourth quarter fiscal 2016. The fourth quarter of fiscal 2017 resulted in a net income of $777,000 compared to a net income of $381,000 in fourth quarter fiscal 2016. Backlog has decreased to $11.4 million at July 14, 2017 compared to a backlog of $11.8 million at July 22, 2016.

During fiscal 2017, we invested approximately $1.5 million in projects focused on product development of new products. We feel these expenditures for the design and development engineering, testing, and certification of new products may help stabilize our long-term revenue and enhance our profits.

This is an exciting time for Butler National Corporation.  Management and all employees are focused on the 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.
