Announcement PDF Adisyn Ltd | ACN 155 473 304 | 1300 331 888 | 2 – 3/4 McGrath Road, Henderson WA 6166 | adisyn.com.au ASX Announcement 16 March 2026 Defence Tech Subsidiary Established Following Radar Signature Reduction Breakthrough Highlights • Adisyn establishes new subsidiary 2D Radar Absorbers Ltd to progress radar signature reduction technologies for Drone, UAV, and other Defence applications • Follows successful demonstration of up to 20dB radar signature reduction using graphene- enhanced composite materials • Ongoing optimisation targeting ~30dB radar reduction, equivalent to a 1,000-fold decrease in radar return signal strength1 • Development program to be conducted in collaboration with Tel Aviv University, led by globally recognised radar physics expert Professor Pavel Ginzburg • Targeted R&D program commencing, including the engagement of a full team supported by Tel Aviv University • The radar signature breakthrough represents a step change in drone and UAV mission success rates and may support a material reduction in the number of drones and UAV’s required. • Application being prepared for Israeli Ministry of Defence grant funding • Market size for military drones alone globally2: US$20.7Bn (2026) US$66.5Bn (2035) • Radar initiative represents a potential lucrative application of Adisyn’s graphene expertise alongside its core semiconductor graphene interconnect program. Progress on the graphene interconnect program continues in accordance with previously disclosed milestones and will be reported separately Adisyn Ltd (ASX: AI1) (“Adisyn” or “the Company”) is pleased to announce the establishment of a new defence technology subsidiary, 2D Radar Absorbers Ltd, following the successful demonstration of up to 20dB radar signature reduction using graphene-enhanced composite materials in testing conducted in collaboration with Tel Aviv University3. The Company is now progressing a Targeted development program aimed at optimising the materials to achieve approximately 30dB radar signature reduction. 1 Refer ASX announcement dated 26 February 2026 2 Refer to Military Drones Market Size & Share 2026 – 2035, Global Market Insights Inc. 3 Refer ASX announcement dated 26 February 2026 Adisyn Ltd | ACN 155 473 304 | 1300 331 888 | 2 – 3/4 McGrath Road, Henderson WA 6166 | adisyn.com.au A reduction of this magnitude represents a massive 1,000-fold decrease in radar return signal strength, meaning a drone that previously appeared as a large object on radar would appear closer to the size of a large insect4 (see Diagram 1). If achieved, such reductions may significantly reduce the radar detectability of drones and UAV platforms and have potential applications across defence, aerospace, and advanced materials sectors.

Targeted Development Program Adisyn has initiated a structured development program with Tel Aviv University to further develop and optimise graphene-enhanced radar absorption materials. The program will be led by Professor Pavel Ginzburg, Full Professor of Electrical Engineering at Tel Aviv University and a recognised global expert in radar physics and electromagnetic materials. As part of the program: • A full-time researcher will be engaged within Professor Ginzburg’s research team 4 Refer ASX announcement dated 26 February 2026 Adisyn Ltd | ACN 155 473 304 | 1300 331 888 | 2 – 3/4 McGrath Road, Henderson WA 6166 | adisyn.com.au • Additional team members from Prof. Max Sokol Lab, focus on synthesis, processing, and property-driven design of advanced composites. • Research will utilise specialised radar and materials laboratories at Tel Aviv University • Work will focus on optimisation of graphene-enhanced composite structures targeting ~30dB radar signature reduction Adisyn has the option to secure exclusive commercialisation rights to the technology developed under the joint research program. Defence Sector Engagement The Company is preparing an application for grant funding support from the Israeli Ministry of Defence, in collaboration with the university development team. The funding application reflects the potential strategic relevance of radar signature reduction technologies in modern drone, UAV and defence systems. Adisyn is also progressing discussions regarding the establishment of an Advisory Board for the new subsidiary, which may include individuals with significant defence and aerospace sector experience. Strategic Positioning The radar signature reduction initiative represents a significant commercial application of Adisyn’s graphene materials expertise. The program is being developed alongside the Company’s primary focus on its graphene semiconductor interconnect technology, which aims to address the performance limitations of copper interconnects in advanced semiconductor devices. Adisyn Ltd | ACN 155 473 304 | 1300 331 888 | 2 – 3/4 McGrath Road, Henderson WA 6166 | adisyn.com.au The Company believes its broader graphene know-how may enable multiple high-value applications across electronics, advanced materials and defence technologies. The establishment of 2D Radar Absorbers Ltd provides a Targeted platform to progress the radar absorption technology and supports potential future strategic partnerships and commercialisation pathways. Comment from Managing Director Arye Kohavi “Recent laboratory results demonstrating a 20dB radar signature reduction highlight the potential of graphene-enhanced materials in radar absorption applications. The establishment of 2D Radar Absorbers allows us to focus Targeted resources on advancing this technology alongside our core semiconductor program. While our primary focus remains on graphene interconnect solutions for next-generation semiconductors, the radar absorption program represents an exciting additional opportunity emerging from our graphene expertise. I can envisage a time in the not-too-distant future where this incredible technology could be spun out into a separate vehicle for the benefit of our shareholders.” Next Steps Key milestones expected over the coming months include: • Finalisation of commercial terms with Tel Aviv University • Expansion of the development program and continued materials optimisation • Submission of the Israeli Ministry of Defence grant funding application • Further technical testing of graphene-enhanced composite structures Adisyn plans to continually update shareholders as key milestones are achieved.
