MANAGEMENT COMMENTARY

“Our positive business momentum carried into the fiscal second quarter, highlighted by significant organic growth in our commercial aerospace and business aviation markets, continued strength in bookings, strong margin realization, and efficient free cash flow conversion,” stated Shahram Askarpour, President and Chief Executive Officer of Innovative Aerosystems.

“In recent months, we’ve completed three acquisitions that, in combination, further expand our base of recurring, high-value aftermarket revenue across legacy and next-generation aviation platforms,” continued Askarpour. “In February, we acquired autopilot product line technology from Moog, serving to expand our flight controls portfolio. In April, we announced two separate asset purchase and licensing agreements with Honeywell that strengthen our integrated cockpit avionics platform, while enhancing our capabilities within aircraft electrical power generation. Together, these transactions are projected to contribute $10 million in annual revenue with a blended gross margin profile of approximately 50%, putting us another step closer to delivering on our $250 million annual revenue target.”

​

​

“In the fiscal second quarter of 2026, we shifted our operational mix to commercial aftermarket and business aviation given the anticipated lower F-16 revenues due to the timing of Improved Programmable Display Generator (“IPDG”) required approvals.  As a result, we generated second quarter revenue of $18.9 million from our non-F-16 business, a 69% increase over the prior-year quarter.  This more than offset a $7 million decline in second quarter F-16 revenue versus the comparable period. As previously reported, revenue associated with the F-16 program was abnormally high in the fiscal second quarter of 2025 due to a planned manufacturing transition at our Exton Facility. The more favorable sales mix also resulted in gross margin of 51.1% in the period, above our targeted mid-40% range. Entering the fiscal third quarter, demand across both our defense and commercial end-markets remains strong.”

​

“We continue to take a disciplined approach to capital allocation, to support profitable growth,” continued Askarpour. “We generated free cash flow of $7.7 million in the first six months of 2026 and more than $13.2 million over the trailing twelve-month period, reflecting improved operating leverage, the benefits of our capital-light model, and our ability to self-fund a greater share of our growth over time. We ended the second quarter with a Net Debt to trailing twelve-month Adjusted EBITDA ratio of 1.7x, up modestly from 1.4x in the year-ago period, after deploying more than $33 million toward strategic investments in the first half of fiscal 2026. We also ended the quarter with $49.8 million of cash and available capacity under our credit facility, providing significant financial flexibility to advance our strategic growth priorities.”

“For the balance of the fiscal year, we expect our business to continue on a favorable growth trajectory, supported by continued strength across our diverse end-markets, momentum in new product launches, targeted investments in accretive, complementary assets that enhance our capabilities and overall value proposition. We remain committed to our strategic priorities, with a focus on maximizing long-term value for our shareholders,” concluded Askarpour.”

SECOND QUARTER FISCAL 2026 PERFORMANCE

Second quarter revenue was $22.4 million, an increase of 2% compa
