According to the company’s 2025 Annual Report, released to the ASX on 17 April 2026, EOS completed the divestment of its non-core naval satellite-communications business, EM Solutions, early in the 2025 financial year and fully repaid its outstanding debt, leaving the group debt-free at year end. The same reporting period included new remote-weapon-system and counter-drone orders across Australia, North America, Europe, the Middle East and South-East Asia, and the company has reported an export order for a 100 kW high-energy laser defence system. EOS’s full-year 2025 results were separately announced to the ASX on 23 February 2026.
