Announcement PDF 17 November 2025 ASX RELEASE NEW SLINGER COUNTER-DRONE ORDER (A$20M) AND BACKLOG UPDATE NEW SLINGER COUNTER-DRONE ORDER (A$20M) Electro Optic Systems Holdings Limited (“EOS” or the “Company”) (ASX:EOS) today announces that it has secured a new order for its Slinger Counter-Drone Remote Weapon Systems (“RWS”) amounting to €11.4m or approximately A$20m. The order is with a Western European NATO country. The systems are intended to address urgent operational requirements and delivery is expected to occur within the next six months. Most of the incremental revenue from this order is expected to arise during 2026. The order includes RWS, spare parts, training and other items. In recent months the drone threat to Western European countries has been increasing. This order demonstrates that EOS’ flagship Slinger Counter-Drone RWS is a product of choice for kinetic counter-drone weapon systems.
