XTI Aerospace Deepens Defense Sector Expertise with Addition of Steve Griessel to Corporate Advisory Board

ENGLEWOOD, Colo., June 11, 2025 /PRNewswire/ -- XTI Aerospace, Inc. (Nasdaq: XTIA) ("XTI"), a pioneer in xVTOL and powered-lift aircraft solutions, named Stephen (Steve) Griessel, former Group CEO of Paramount Group Ltd., to its Corporate Advisory Board. His addition follows growing recognition of VTOL aircraft as a national strategic priority, as highlighted in President Trump's recent executive order.

"Steve brings deep aerospace and defense experience as well as a global mindset," said Scott Pomeroy, CEO and Chairman of XTI. "His appointment comes at a pivotal time as XTI executes on its strategy to dominate the emerging Vertical Economy—where aviation missions demand the speed, range, and adaptability that only xVTOL can deliver. We believe Steve's proven ability to transform defense enterprises into globally scaled OEMs will directly accelerate XTI's push into mission-critical markets—making XTI a competitive force in both commercial and defense verticals."

Mr. Griessel is a seasoned executive with over 40 years of leadership experience in defense, aerospace, investment, tourism, and manufacturing. He currently serves as CEO of Copperstone Capital Partners, the Ichikowitz family's asset management entity overseeing a portfolio of investments in a variety of sectors including software and defense.

Previously, Mr. Griessel was Group CEO of Paramount Group Ltd, a global aerospace and defense original equipment manufacturer (OEM), where he led the company's transformation into a globally licensed OEM, deploying IP and manufacturing in 25+ countries—delivering advanced capabilities in sovereign defense. This aligns directly with XTI's strategy to serve high-value special mission operators and defense partners seeking VTOL solutions without reliance on new infrastructure.

"I've spent my career scaling organizations that marry innovation with execution," said Mr. Griessel. "XTI's vision for the TriFan 600 is transformative—delivering the vertical lift of a helicopter with the speed and range of a fixed-wing aircraft. I'm honored to contribute to this mission and help position XTI as a leader in the future of regional and mission-critical air mobility."

Michael Tapp, Chairman of XTI's Corporate Advisory Board, added, "Steve's global business acumen, his success leading defense and aerospace enterprises, and his investor mindset make him an invaluable asset as we develop a world-class military variant that leverages our TriFan platform."

Mr. Griessel has a Bachelor of Business degree from the University of the Witwatersrand, a postgraduate degree in Marketing from the University of South Africa, and a Master of Science degree in Building Science from the University of the Witwatersrand.
