Management Comments

Adam Sefchick, Interim Chief Executive Officer of Butler National Corporation, commented on the results stating, "Butler National delivered record first-quarter earnings in fiscal 2027. These results reflect the dedication of our employees, the continued execution of our strategic initiatives, and our focus on operational efficiency across the organization. Revenue increased 53% to $30.8 million, operating income increased 59% to $7.4 million, and net income increased 43% to $5.3 million compared to the first quarter of fiscal 2026.

Importantly, our significant revenue growth translated into continued strong profitability, with operating margin increasing to 24% compared to 23% in the prior-year quarter. Earnings per share increased to $0.08 from $0.06, reflecting improved operating performance during the quarter. We also continued our disciplined approach to capital allocation, including ongoing share repurchases and investments in our businesses.

Within our Aerospace Products segment, strong performance from both Avcon Aircraft Modifications and Butler National-Tempe contributed significantly to our results, while Aerospace Products backlog reached a record $51.1 million. At

Avcon, we achieved several significant milestones, including the successful completion and delivery of two Challenger 605/650 modification projects that included our recently approved STC for the under-fuselage radome/pod and rails for mounting of sensors. In addition, Avcon completed a complex special mission systems integration project, delivering a CASA CN-235 aircraft upgraded with a new sensor package that included a new Avcon-designed custom workstation. The project demonstrates Avcon's expanding capabilities beyond structural aircraft modification to provide more comprehensive special mission systems integration solutions, while creating opportunities for derivative products and potential follow-on installations. Special Mission Electronics (Tempe) continued to experience strong customer demand and increasing production volumes.

The increased sales of Avcon aircraft modification kits for customer installation also contributed to revenue and margin performance during the quarter. These included Cessna Caravan camera port modification kits, as well as Avcon rails and Special Mission Pod kits for the King Air. Kit sales remain an important part of our strategy to leverage Avcon's engineering and certification capabilities while expanding our geographic reach.

These results reflect the continued execution of strategic initiatives implemented over the last several years, including investments in new product development, manufacturing capabilities, and operational efficiency. We remain focused on customer satisfaction, operational excellence, and disciplined growth."

Jeffrey Yowell, Executive Chairman, commented: "Butler National's strong first-quarter results demonstrate the continued momentum across our businesses and the effectiveness of the strategy we have been executing. On behalf of the Board of Directors, I want to thank our employees for their continued dedication to serving our customers and executing at a high level every day.

As Butler National enters its next chapter of leadership and growth, the Board and management team remain focused on maintaining stability and continuing to execute the Company's strategic and operational priorities. While the Board conducts its search for a permanent Chief Executive Officer, we remain confident in Adam and our experienced leadership team and their ability to continue advancing the business.

Our objective remains to build upon the momentum already established across Butler National by investing in our capabilities, improving operational execution and pursuing disciplined opportunities for long-term growth and shareholder value creation."

Stockholders' equity increased 5% during the first quarter of fiscal 2027 while long-term liabilities declined 3%. During the first quarter of fiscal 2027, we repurchased 246,996 shares of our outstanding common stock for cash under our share repurchase program and as part of our ongoing capital allocation strategy.

Business Segment Highlights

Aerospace Products:

Revenue from the Aerospace Products segment increased 92% to $21.7 million in the first quarter of fiscal 2027 compared to $11.3 million in the first quarter of fiscal 2026. The increase in revenue was primarily driven by a $10.7 million increase in aircraft modification activity and a $0.7 million increase in the sales of Special Mission Electronics, partially offset by a $0.9 million decrease in Aircraft Avionics. Aircraft Modifications experienced higher activity across multiple programs, including increased work on larger and more complex special mission aircraft projects, as well as repeat modifications utilizing previously developed STCs.

Revenue also benefited from increased sales of modification kits for field installation, including Cessna Caravan camera port modification kits and Avcon rails and Special Mission Pod kits for the King Air, among others. Additionally, Avcon completed and delivered two Special Mission Challenger 605/650 modification projects that included our recently approved STC for the under-fuselage radome/pod and rails for mounting of sensors.

Aerospace Products operating income increased 91% compared to the prior-year quarter, while the segment maintained an operating margin of approximately 25% despite the significant increase in revenue and activity.

Butler National-Tempe continued to experience strong demand for its specialized electronic control systems and defense-related products, including deliveries of M134 minigun gun control units. Special Mission Electronics revenue increased

$0.7 million during the quarter, supported by increased production activity, additional customer orders and production efficiencies.

Professional Services:

Revenue from the Professional Services segment increased 3% to $9.0 million in the first quarter of fiscal 2027 compared to $8.8 million in the first quarter of fiscal 2026.

Traditional casino gaming revenue increased $0.4 million due to increased patron spending. This increase was partially offset by a decrease in sports wagering revenue through the DraftKings sports wagering platform, which decreased to $1.1 million for the three months ended July 31, 2026, compared to $1.3 million for the three months ended July 31, 2025. Non-gaming revenue at Boot Hill Casino increased slightly to $1.1 million for the three months ended July 31, 2026, compared to $1.0 million for the three months ended July 31, 2025. The Company continues to pursue initiatives designed to increase visitation and enhance the entertainment offerings at Boot Hill Casino & Resort, including the development of the adjacent Glo Hotel property by a local hospitality provider.

Backlog:

As of July 31, 2026, Aerospace Products backlog totaled a record $51.1 million. Backlog represents contracted business that meets the Company's criteria for inclusion and includes orders that may not be completed within the next fiscal year. The timing of revenue recognition can vary based on customer schedules, aircraft availability, engineering and regulatory requirements, material availability and other factors.
