The news: Defence and counterdrone manufacturer Electro Optic Systems’ shares fell in afternoon trade after the Federal Court formally ordered it pay a $4 million penalty for breaching continuous disclosure requirements.
The numbers: At 1:47pm AEST, shares in EOS slid 5.1% to $9.40, with the stock down 5.5% since the start of the year.
The context: Justice Ian Jackman found that, based on the facts and admissions agreed by EOS and corporate regulator ASIC, EOS failed to disclose a materially significant 2022 revenue forecast for about 14 weeks.
In his judgment, Jackman characterised the $4 million fine as “sufficiently substantial, having regard to EOS’s size and financial resources, to achieve both specific and general deterrence, without being oppressive or disproportionate”.
After market close on Wednesday, EOS told the exchange the judgment was made earlier in the day.
ASIC has separately commenced proceedings against the former EOS CEO and director Ben Greene for an alleged breach of directors’ duties.
Separate to these cases, Electro Optic Systems in March 2026 also had to update its continuous disclosure policy after the ASX found that a conditional high energy laser contract announced in December 2025 “failed to adequately describe market sensitive information”.
What they said: “This result demonstrates that continuous disclosure is fundamental to keeping investors properly informed,” ASIC chair Joe Longo said.
“When a listed company becomes aware of material changes to guidance, it must act promptly to disclose these to the market,” he said.
“Delays in correcting market‑sensitive information undermine market integrity and investor confidence.”
