Management Comments

“The quarter-ended July 31, 2021 was a robust start to fiscal year 2022. Both the Professional Services and Aerospace Products segments experienced significant revenue increases. Revenue increased 40% to $18.1 million in the three months ended July 31, 2021, as compared to $13.0 million in the three months ended July 31, 2020. The increase in revenue reflects an increase of 10% in Aerospace Products revenue and an increase of 82% in Professional Services revenue. We continue to focus on growth in international markets, solutions for regulatory mandates and the development of new supplemental type certificates (“STCs”). This includes significant global efforts.

First quarter fiscal 2022 net income was $2.9 million compared to a net loss of $15,000 in the first quarter fiscal 2021. First quarter fiscal 2022 operating margin was 22% compared to 1% in first quarter fiscal 2021. We continue to work to improve efficiencies in our implementation, operational processes, and controlling general and administrative expenses.

During the three months ending July 31, 2021, we invested approximately $326,000 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.

Backlog:

As of July 31, 2021, our backlog totaled approximately $24.1 million. The backlog includes firm, pending, and contract orders, which may not be completed within the next fiscal year. This is standard for the industry in which modifications services and related contracts may take several months or years to complete. Such actions force backlog as additional customers request modifications but must wait for other projects to be completed. There can be no assurance that all orders will be completed or that some may ever commence.
