EOS Shares Slump on Grizzly Research Claims, Backlog in Focus

13.02.2026 - 09:00:31

Electro Optic Systems (EOS) is facing intense selling pressure after a critical report from Grizzly Research, a U.S. short-seller, accusing the Australian defense group of aggressive, misleading statements and even outright fabrications. The stock fell again on Thursday, sliding 7.81% to AUD 6.14, adding to a slide that has erased most of its prior gains from a mid-January peak.

From a recent all-time high of AUD 11.02 reached in mid-January, the shares have dropped by more than 44%. The trigger for the fresh wave of selling was Grizzly Research?s report, which alleges the management?s statements were misleading and unreliable.

At the heart of the critique are purportedly misstated revenues connected to EOS?s January 2026 MARSS acquisition. The short-seller also questions how EOS has communicated about potential new contracts in South Korea, casting doubt on the company?s revenue outlook.

EOS issued a forceful rebuttal, calling the Grizzly analysis manipulative. The company noted that an otherwise disputed $80 million laser contract with South Korea is conditional and explicitly not included in the confirmed order backlog of AUD 459 million. Legal teams in Australia and Germany are examining possible actions against Grizzly Research.

Should investors sell immediately? Or is it worth buying EOS?

Even after this severe pullback, EOS has managed a year-to-date gain of about 365%. Amid the turbulence, EOS unveiled a new alliance with Turkey?s defense contractor ROKETSAN to co-develop integrated drone-defence systems, signaling ongoing strategic momentum despite the pressure.

Investor confidence has been severely dented in the near term. Going forward, the key for EOS will be to demonstrably validate the quality of its order pipeline and convert conditional offers into firm revenue. The trajectory of the stock will likely hinge on how legal matters unfold and how thoroughly EOS can verify and execute its backlog.
