EOS launches A$175m capital raising on the back of MARSS order book surge

Electro Optic Systems Holdings Limited (ASX: EOS) has launched a capital raising of up to A$175 million, comprising a fully-underwritten A$150 million institutional Placement and a non-underwritten Share Purchase Plan (SPP) targeting up to A$25 million, with both instruments priced at A$8.00 per New Share. The raise is anchored by a significant commercial development: MARSS, the counter-drone software business EOS is acquiring, has secured €102 million (~A$165 million) in new Middle East orders, lifting MARSS’ order book to €135 million (~A$217 million). Subject to transaction completion, EOS’ total illustrative order book would grow from A$509 million to A$726 million.

What’s driving the raise — a surging MARSS order book and Middle East demand

NiDAR system wins £85m (~A$160m) contract with Middle Eastern defence force

MARSS has entered into a £85 million (~A$160 million) contract with the national defence force of a country in the Middle East, expanding its existing NiDAR Command and Control (C2) installations to deliver a country-wide drone detection and mitigation capability. The contract reflects an existing customer relationship, with MARSS building on prior deployments in the region.

Delivery is front-loaded: approximately 70% of revenue and cash is expected to be earned during 2026 and 2027, with the remaining balance recognised over the following three years via support services. Active conflicts across the Middle East have driven a demonstrable increase in customer enquiry for counter-drone capabilities, which management attributes to the strong performance of the NiDAR platform in the region.

EOS’ own pipeline building momentum

EOS has recorded significant contract wins in 2026 to date, including a A$60 million Counter-Drone order in March 2026 and A$170 million in new C2 Counter Drone contracts for MARSS. Of the unconditional illustrative order book of A$726 million, approximately 60–80% is expected to convert to revenue in 2026 and 2027.

The company also reports growing enquiries for its Counter-Drone solutions, including Slinger and High Energy Laser, supported by the volatile geopolitical environment and strong customer engagement across target regions. The order opportunity pipeline is described as dynamic and rapidly evolving.

Date EOS Order Book (A$m) MARSS Order Book (A$m) Combined Illustrative (A$m)
31-Dec-24 $136m
31-Dec-25 $459m
15-May-26 $509m $217m $726m

How the capital raising works — Placement, SPP, and use of proceeds

Placement and SPP structure

The Placement will result in the issue of approximately 18.8 million New Shares at A$8.00 per share, representing a 9.3% discount to the last traded price and approximately 9.7% of EOS’ current issued capital. The raise is fully underwritten by Macquarie Capital, Bell Potter and Canaccord Genuity as Joint Lead Managers.

The SPP is open to eligible shareholders with a registered address in Australia or New Zealand as at 15 May 2026, allowing each to apply for up to A$30,000 worth of New Shares at the same A$8.00 Placement Price. EOS targets up to A$25 million via the SPP, with scale-back provisions applying if applications exceed that amount. Key SPP dates are:

  • SPP opens: Monday, 25 May 2026
  • SPP closes: Tuesday, 9 June 2026
  • Results announced: Friday, 12 June 2026
  • New Shares issued: Tuesday, 16 June 2026

Where the money goes

Proceeds from the Capital Raising, together with the Washington H. Soul Pattinson secured term loan facility (which retains A$30 million available for future drawdown), will be applied to:

  1. Fund the upfront consideration of the MARSS acquisition (€36m cash; unchanged)
  2. Increase flexibility to pursue growth opportunities and execute on strategic initiatives
  3. Provide working capital flexibility, including long lead parts investment and flexibility for customer terms/bond requirements
  4. Accelerate commercialisation of new products
  5. Pay transaction costs

Following completion of the acquisition and Capital Raising, EOS is expected to hold a pro-forma net cash balance of approximately A$195 million, calculated as at 31 March 2026 (A$95 million cash, less A$50 million paid to acquire MARSS, plus A$150 million Placement proceeds, excluding the SPP).

What is a counter-drone C2 system — and why investors should pay attention

A Command and Control (C2) counter-drone system is a technology platform that detects, identifies, tracks, and neutralises unmanned aerial vehicles (UAVs, commonly called drones) across a defined area or network. Rather than being a single piece of hardware, a C2 system acts as the intelligence layer that coordinates sensors, communications, and response tools across multiple locations simultaneously.

MARSS’ NiDAR platform is a software-led C2 system designed to protect critical infrastructure and military installations from drone threats. It integrates with existing hardware deployments to provide operators with real-time awareness and the ability to direct countermeasures. Because NiDAR is software-led, it is inherently scalable: the same platform can be expanded across new sites, updated with improved capabilities, and supported under ongoing service contracts.

This is precisely the revenue model illustrated by the new Middle East contract, where the initial deployment is followed by a three-year support services tail generating recurring cash flows. As drone warfare proliferates globally, software-led C2 platforms like NiDAR offer investors a combination of large upfront contract revenue and predictable, recurring income from ongoing support, upgrades, and network expansion.

Amended MARSS acquisition terms — earnout cap raised to €140m

In light of MARSS’ strengthening commercial trajectory, EOS and the MARSS vendors have agreed amendments to the transaction terms originally announced on 12 January 2026. The key investor-relevant changes are as follows:

The upfront cash consideration of €36 million remains unchanged. The maximum earnout cap has been increased from €100 million to €140 million, reflecting the improved commercial outlook for the business. The earnout structure has also been restructured from two tranches to three tranches, payable at 90 days from completion, 270 days from completion, and at the end of the earnout period (31 May 2027).

The first earnout tranche (covering up to €100 million in contingent consideration on the first €500 million of order intake) remains payable in EOS shares at the previously agreed conversion price of A$7.40 per EOS share. This is the MARSS acquisition earnout conversion price and is distinct from the A$8.00 Placement price. A further €40 million in earnout consideration (on an additional €200 million of order intake) is payable at a New Conversion Price equal to the 5-day volume weighted average price of EOS shares prior to acquisition completion, which has not yet been determined.

The maximum number of EOS shares issuable under the earnout is 28,942,814, representing 15% of EOS’ currently issued share capital (the “placement capacity cap”). Any earnout amounts exceeding the value of shares issuable under that cap are payable in cash. Additionally, subject to a suitable candidate being nominated, EOS has agreed to appoint a MARSS management shareholder nominee to the EOS Board if that group collectively holds more than 15% of EOS’ issued share capital. The increased earnout cap aligns vendor incentives directly with the delivery of order book growth, benefiting EOS shareholders if MARSS continues its current commercial momentum.
