Why is this ASX defence stock rocketing 10% today?

Electro Optic Systems Holdings Ltd (ASX: EOS) shares are catching the eye on Wednesday.

At the time of writing, the ASX defence stock is up 10% to $4.92.

Why is this ASX defence stock surging?

There have been a couple of reasons why investors have been snapping up EOS shares today.

The first is news that it has completed the transaction to acquire the UK-based Interceptor business from MARSS Group. This transaction was previously announced last week on 19 November 2025.

According to the release, under the transaction, EOS has acquired all Interceptor assets, as well as the specialist engineering team that developed the system.

The total investment of 5.5 million euros (approximately $10 million) has been funded from EOS’ existing cash reserves.

Development of this advanced prototype is expected to take a further 12-24 months before full commercial launch. This is expected to require further investment of up to $10 million over the next three years.

Management believes the acquisition broadens EOS’ counter-drone effector portfolio, extends EOS’ software and AI capabilities, and initiates EOS’ presence in the United Kingdom, which is an important AUKUS partner market.

What else?

The ASX defence stock also revealed that it has settled ASIC’s investigation in relation to certain disclosure matters in 2022. The settlement includes an agreed proposed penalty of $4 million, which requires the approval of the Federal Court.

This settlement relates to an investigation by ASIC in connection with the company’s 2022 revenue guidance.

It highlights that it navigated a challenging environment in 2022 marked by strategic, financial, and operational pressures. But it concedes that it accepts ASIC’s conclusion that it breached its continuous disclosure obligations in the period from 25 July 2022 to 31 October 2022.

ASIC has indicated that it intends to bring separate proceedings against Dr Ben Greene (former CEO and current Chief Innovation Officer of EOS). This is in relation to the same revenue guidance issues. Dr Greene is not a party to this settlement.

EOS’ chair, Garry Hounsell, said:

This outcome represents a constructive resolution with ASIC that allows the business to move forward with clarity, removing the potential of protracted litigation on the matter. We believe this outcome is in the best interests of the Company and its shareholders. Since late 2022, we have made significant progress in strengthening our business and remain committed to best-practice and transparent communication. As we look to the future, we are well-positioned to execute our strategic priorities and deliver long-term value for our shareholders.
