XTI Aerospace Selects Drivetrain Supplier-Partners for TriFan 600

XTI Aerospace, Inc. (Nasdaq: XTIA) ("XTI"), a pioneer in xVTOL and powered-lift aircraft solutions, today announced the selection of Triumph Geared Solutions, Formsprag Clutch, and Kamatics Corporation as key supplier-partners for the design, development and manufacture of the drivetrain system for XTI's revolutionary TriFan 600 vertical takeoff and landing (xVTOL) airplane.

Announcement of the drivetrain suppliers meets a key Q2 2025 product and engineering milestone announced in a prior press release. Execution of definitive agreements between the parties is forthcoming.

Under the planned teaming arrangement:

• Triumph Geared Solutions will design, develop, and manufacture the primary and secondary gearboxes that manage power distribution across the TriFan's propulsion system.
• Formsprag Clutch will design, develop and manufacture the clutch systems within the TriFan's drivetrain.
• Kamatics Corporation will design and manufacture the precision shafts that ultimately connect the twin turboshaft engines to the TriFan's three ducted fans.

XTI, Triumph Geared Solutions, Kamatics, and Formsprag Clutch recently held a collaborative two-day summit bringing together top engineers, executives, and technical specialists to accelerate progress on the high-performance drivetrain solution for the TriFan 600 xVTOL aircraft. The companies discussed fault tolerant drivetrain configurations, thermal management and lubrication systems, advanced materials and lightweight design, and system integration for maintainability as well as aligned on key design principles, integration milestones, and validation protocols for the drivetrain architecture.

"Partnering with these suppliers is more than a technical collaboration — it's about shaping the future of flight," said Scott Pomeroy, Chairman and CEO of XTI Aerospace. "The collective expertise and shared vision represent the foundation of an aircraft drivetrain system that we believe will redefine what's possible."

Pete Gibson, President of Triumph Geared Solutions, shared, "We look forward to contributing our expertise in high-performance aerospace gearboxes to XTI's next-generation aircraft. This partnership reflects Triumph's ongoing commitment to advancing future-forward aviation technologies."

Laurent Crosnier, VP and General Manager of Regal Rexnord's Clutches & Brakes business added, "Formsprag Clutch is excited to be an integral part of XTI's transformational VTOL aircraft. Creating a highly reliable and innovative drivetrain solution is a critical subsystem, and we look forward to this challenge."

Kevin Ladouceur, General Manager of Kamatics Corporation, stated, "KAMATICS is honored to be selected by XTI for its pioneering aircraft. Our customized driveshaft technologies are well-suited to meet the demanding performance and durability requirements of the TriFan 600's propulsion system."

The TriFan 600 is designed to combine the speed, range, and comfort of a business airplane with the vertical takeoff and landing capabilities of a helicopter. The aircraft's twin turboshaft propulsion system and pivoting ducted fans will allow for vertical lift, efficient forward flight, and smooth transitions in between — offering unprecedented flexibility and performance in regional air mobility.
