Wilmington, MA, USA – June 25, 2026 – Liberty Defense Holdings Ltd. (“Liberty,” “Liberty Defense” or the “Company”) (NASDAQ: DETX; TSXV: SCAN), a leading technology provider of AI-based next generation detection solutions for concealed weapons and threats, is pleased to announce that its HEXWAVE™ system has been selected for deployment at a major international airport in the United States for aviation worker screening operations. The award represents another significant milestone in Liberty Defense’s continued expansion across the aviation sector as airports enhance security programs to support evolving Transportation Security Administration (TSA) worker screening requirements.

The airport serves over 30 million domestic and international passengers annually and is one of the top 20 busiest airports in the United States.

The HEXWAVE™ systems will be utilized at designated aviation worker screening checkpoints to provide fast, contactless screening. HEXWAVE™ leverages millimeter wave technology, advanced 3D imaging, and artificial intelligence to identify concealed metallic and non-metallic weapons and threats, including liquid, plastic, and powder explosives as well as 3D-printed weapons and other prohibited items. The deployment is intended to enhance overall airport security operations while improving throughput efficiency and the screening experience for aviation personnel.

“Securing another major U.S. airport reflects the growing demand for next-generation screening technologies that improve both safety and operational efficiency,” said Bill Frain, CEO of Liberty Defense. “We now have installations at several of the nation's busiest airports and transportation hubs, and we are proud to support their commitment to deploying advanced, contactless security solutions that address evolving threat environments while enhancing the experience for aviation workers.”

In addition, CEO Bill Frain will participate in a webcast fireside chat at Maxim Group’s Defense Tech Virtual Conference, Thursday, June 25, 2026, at 10:30 am ET (Track 2). The conversation will be led by Maxim Group Equity Analyst Jack Vander Aarde, including Q&A.
