Page 1 26 October 2026 ASX RELEASE QUARTERLY ACTIVITY REPORT & APPENDIX 4C FOR THE QUARTER ENDED 30 SEPTEMBER 2026 The consolidated entity, consisting of Electro Optic Systems Holdings Limited and the entities it controlled during the quarter, (“EOS” or the “Group”) has filed its Appendix 4C and provides the following update on its activities for the quarter ended 30 September 2026. HIGHLIGHTS → Available cash at 30 September 2026 was $133m, a decrease of $123m from 30 June 2026. The decrease arose mainly due to investment in temporary working capital and in cash security deposits for bank guarantees, both related to MARSS contracts. More details are included at page 4 below. → As at 23 October 2026, following cash receipts arising on MARSS contracts in the Middle East, the available cash was $204m. → In addition to available cash, EOS had a further $30m of available funding from undrawn debt facilities at 30 September 2026 and 23 October 2026. → Not included in the cash balance above, at 30 September 2026, EOS had a further $147m of cash security deposits held with banks to support bank guarantees and bonds. → The Order Book at 30 September was $717m (a 56% increase from 31 December 2025). → After the end of the quarter, EOS announced that it had entered into a conditional contract with Kuwait for the provision of a nation-wide counter-drone defence system valued at £370m (approximately A$700m). Including this contract, EOS’ combined total Order Book1 is over A$1.4bn → EOS has secured a Letter of Intent with the Netherlands Ministry of Defence in relation to EOS’ Apollo High Energy Laser Weapon technology, including for work on pathways to a fully operational weapon system and a potential future production facility in the Netherlands. → EOS has made further investments in growth, including the appointment of a new EVP Corporate Strategy, Nicolas Chamussy, (most recently CEO of KNDS France) to support global growth.

ASX Listing Rules Appendix 4C (17/07/20) + See chapter 19 of the ASX Listing Rules for defined terms. Page 2 KEY ACTIVITIES MARKET AND BUSINESS DEVELOPMENT ACTIVITY → During the quarter, conflicts continued, particularly in Europe in the Middle East. These conflicts have continued to drive market need and customer enquiry, particularly for counter-drone products. → EOS held several meetings with current and potential new customers in the UAE, Saudi Arabia, Qatar, Bahrain, Kuwait, Jordan and other countries. Many discussions focussed on counter-drone nationwide and critical infrastructure protection requirements. → Customer discussions continued with the Netherlands Ministry of Defence regarding follow-on opportunities under the ongoing 100kW High Energy Laser Weapon (“HELW”) contract (previously announced on 5 August 2025). → In September, EOS announced that it had signed a Letter of Intent with the Netherlands Ministry of Defence relating to EOS’ Apollo HELW technology. Under the letter of intent, the Netherlands Ministry of Defence and EOS will explore pathways for (1) Apollo to become a fully operational weapon system for the Netherlands, and (2) the opportunity to establish a production facility in the Netherlands, supported by a Dutch-led European supply chain. → During the quarter, EOS continued discussions with UAE-based Generation 5 to further advance our JV to develop a 200-300kW HELW product and to manufacture a 100-150kW HELW in the UAE. Full details were previously announced on 19 June 2026. → In September, in the United States, EOS’ R400 Remote Weapon System (“RWS”) was listed on the US Joint Interagency Task Force (JIATF) 401 Counter-UAS Marketplace. The marketplace provides an additional pathway for US Government and participating allied customers to evaluate and procure the system as part of their counter-drone capability requirements. → In September, EOS signed a MOU with Mahindra Defence Ltd for partnership in High Energy Laser systems and R400 CUAV applications for the Indian market. → During the quarter, EOS continued reviewing the Korean HELW market. This included discussions with Goldrone in relation to the conditional US$80m contract to manufacture and supply a 100kW HELW, (as initially announced on 15 December 2025). As previously announced, EOS believes that satisfaction of the conditions under the Goldrone contact have been delayed and could be finalised in 2027. → In EOS Space Systems, market development activities continued, including demonstrations of the Atlas Space Control product range for potential international customers. Work also continued on the development of a mobile demonstration capability, planned for demonstration in Europe in 2027. → There is no guarantee that any of the above opportunities will be realised in the form of binding sales contracts or any guarantee regarding the timing of revenue recognition and cash flows that may ultimately arise, if any. CUSTOMER ORDER ACTIVITY → EOS Defence Systems secured a ~A$23m order for its Naval R400 RWS, to be supplied to a new customer based in the Middle East (as announced on 2 July 2026). → During the quarter, EOS’ US business received orders totalling US$15m (A$22m) for a range of RWS products and product development work mainly for large established US defence contractors. → EOS MARSS secured an £8m (~A$15m) order for an existing customer in the Middle East to supply a new counter-drone command and training centre (as announced on 2 July 2026). → EOS MARSS secured a ~A$8m contract with a new customer in the Middle East for an integrated counter-drone system with MARSS’ NiDAR at its core (as announced on 27 July 2026). → After the quarter end, EOS Space Systems secured a new A$9.5m contract with the Australian Space and Cyber Capability Development Branch (VCDF Group) for the development of advanced space- related systems, further strengthening the Group's position as a provider of Australian sovereign space technologies and services. ASX Listing Rules Appendix 4C (17/07/20) + See chapter 19 of the ASX Listing Rules for defined terms. Page 3 → After the end of the quarter, on 9 and 12 October 2026, EOS announced that it had entered into a conditional contract with the government of Kuwait (“Kuwait Contract”). The contract is for the provision of a nation-wide counter-drone defence system valued at £370m (approximately A$700m). The contract will involve the deployment of an integrated counter-drone system utilising MARSS' NiDAR command-and-control technology, with EOS acting as the prime contractor and systems integrator. → The Kuwait Contract remains subject to the satisfaction of certain conditions, including the provision by EOS of a £74m (~A$150m) advance payment guarantee and receipt of the corresponding customer advance payment (also £74m or ~A$150m). In addition, the conditions include that EOS obtains relevant export licences for various components of the system within two months following receipt of necessary documentation from the customer. A performance bond guarantee of £37.1m (~A$70.4m), was provided to the customer by EOS and this was secured by a cash deposit payment of £40.3m (~A$76.5m), during the quarter ended 30 September 2026. Other important terms and conditions were announced on 9 October 2026. → EOS is currently in discussions with the Kuwait Contract customer which could lead to (1) changes in contract terms (including the amendment of the £74m (~A$150m) advance payment and related bank guarantee obligation), (2) changes in the timing of export licencing for components, and/or (3) the formalisation of the contract as unconditional. There is no certainty as to whether these discussions will lead to a binding contractual amendment; or as to when, or whether, the outstanding conditions will be satisfied. In the event that amendments are secured, EOS will update the market. ORDER BOOK → The Order Book at 30 September 2026 was $717m, representing a $259m or 56% increase from 31 December 2025. This order book does not include the conditional Kuwait contract which was signed after the end of the quarter on 9 October. MANUFACTURING AND DELIVERY ACTIVITY → In EOS Defence Systems in Australia and the United States the Group continued the manufacture and delivery of RWS for customers in the United States, Europe, the Middle East, South East Asia and Australia. → In addition, EOS continued work at the Singapore HELW manufacturing facility on the 100kW HELW project for the Netherlands Ministry of Defence. → In MARSS, work continued regarding the procurement of key OEM components (including optical sensors, radars and missiles) and the delivery of these to customer sites in the Middle East. → EOS Space Systems progressed project delivery across both its Australian and New Zealand operations. To support future growth and delivery, Space Systems invested in setting up a development and manufacturing facility for ATLAS products, enhancing its capacity to design, manufacture and deliver advanced space systems for Space Control. REVENUE AND OUTLOOK → EOS announced on 25 August 2026 the expected 2026 full year revenue for the EOS business (including MARSS) to be $360m - $400m. If secured, this would represent a record annual revenue for EOS. No change to this outlook has arisen as at the date of this report. → The revenue outlook assumes that there is no unforeseen significant deteriorations in global supply chains or other factors that could impact EOS production activity, delivery to customers or other factors that impact revenue recognition by EOS. MARSS ACQUISITION UPDATE → In August 2026, the first tranche of the MARSS acquisition earn-out was completed, with €120.3m of qualifying orders received, resulting in earn-out consideration of €24.1m. Of this, €23.9m is expected to be settled in the coming weeks through the vesting of performance rights into EOS shares and the remaining €0.2m was settled in cash during the quarter. ASX Listing Rules Appendix 4C (17/07/20) + See chapter 19 of the ASX Listing Rules for defined terms. Page 4 MANAGEMENT CHANGES – INVESTMENT IN GROWTH → During September 2026, EOS appointed Nicolas Chamussy to the role of EVP Corporate Strategy, based in Europe. The Group believes there are substantial market growth opportunities continuing to emerge and has added Nicolas’ capability to help maximise future growth. → Nicolas has over 30 years of experience leading large, complex organisations across government, Airbus and KNDS, managing multi-billion-euro businesses and workforces of up to 5,000 employees. Nicolas was most recently CEO of KNDS France where his responsibilities included maximising European growth. FINANCIAL SUMMARY EOS’ available (i.e. unrestricted) cash holdings at 30 September 2026 was $133.1m, representing a $122.9m decrease from the unrestricted cash holdings at 30 June 2026. The decrease was primarily driven by: → Operational cash outflows (particularly relating to investment in temporary working capital on MARSS contracts). After the end of the quarter, this investment was recovered by cash receipts arising on contracts in the Middle East. → Investment of $80.0m in cash security deposits for bank guarantees (also primarily relating to MARSS contracts); and → Partially offset by the receipt of $30.0m proceeds from the Strategic Placement, following the issuance of shares in July 2026. Each of these are detailed below. After the end of the quarter, the available cash as at 23 October 2026 was $204.0m, an increase of $70.9m on the position at 30 September 2026. In addition to the above unrestricted cash holdings, at 30 September 2026, the Group had a further $147.1m of cash security deposits held with banks to support bank guarantees and bonds, representing a $76.9m increase from 30 June 2026. The Group has received positive indications of support from entities representing the Australian Government and the UK Government and is in discussion with these entities and group funding providers with a view to reducing the level of cash security deposits required to be held in relation to certain bank guarantees and bonds. At 30 September 2026, the Group's total cash holdings, including cash security deposits, were $280.2m. OPERATING CASH FLOWS The Net Cash outflow from Operating Activities for the quarter was $57.2m, compared to a Net Cash outflow of $17.6m in Q2 2026. Receipts from customers totalled $159.1m for the quarter, representing an increase of $92.8m compared to Q2 2026. The increase reflects higher cash collections from customer contracts during the quarter. As noted above, as at 30 September 2026 the unconditional contract backlog was $717m. This order book does not include the conditional Kuwait contract which was signed after the end of the quarter on 9 October. The order book of $717m represents a 56% increase on the position at the start of the year. EOS expects in future to benefit from cash receipts arising from this growth in order book. Other cash flows from operating activities (excluding cash receipts from customers) amounted to net payments of $216.0m during the quarter, compared to $83.9m in Q2 2026. The increase primarily reflects higher payments for product manufacturing and operating costs of $157.0m, compared to $37.4m in Q2 2026. This included a large payment to a MARSS supplier to support a key customer delivery in Q4 2026 (and related customer cash collection); higher manufacturing activity levels and investment in long-lead inventory items to support future customer deliveries. Other payments included $32.4m for staff costs and $19.6m for administration and corporate costs. Both of these increased due to higher activity levels. ASX Listing Rules Appendix 4C (17/07/20) + See chapter 19 of the ASX Listing Rules for defined terms. Page 5 Payments made during the quarter supported both current and future customer deliveries and associated customer cash receipts. OTHER CASH FLOWS The Net Cash outflow from Investing Activities for the quarter was $94.3m, compared to an outflow of $85.6m in Q2 2026. The outflow primarily reflects $80.0m of payments for cash security deposits supporting bank guarantees and bonds issued for customer contracts. This included a £40.3m (~A$76.5m) cash security deposit provided in August 2026 to support a performance bond guarantee in connection with MARSS Kuwait Contract (see details above, and as announced on 9 and 12 October 2026.) Investing outflows also included $13.3m for property, plant and equipment and intangibles, (including customer-funded investment) $0.3m for the MARSS acquisition earn-out payment to a shareholder who elected to receive the consideration in cash, and $0.6m for acquisition-related transaction costs. The Net Cash inflow from Financing Activities for the quarter was $27.9m, compared to an inflow of $263.8m in Q2 2026. Financing cash inflows included the remaining $30.0m proceeds from the Strategic Placement received in July 2026 and $0.04m from the exercise of share options. These inflows were partially offset by $0.8m of share issue transaction costs and $1.3m in repayments of lease liabilities. ISSUANCE OF EQUITY SECURITIES During the quarter, EOS issued 5,000,000 fully paid ordinary shares at $8.00 per share under the $40.0m Strategic Placement, following shareholder approval at the Extraordinary General Meeting held on 26 June 2026. Of the total proceeds, $10.0m was received before 30 June 2026, with the remaining $30.0m received in July 2026. Cash receipts of $39,000 arose during the quarter from the issuance of equity securities, representing receipts from the exercise of share options issued under EOS Omnibus Employee Incentive Plan (‘OEIP’). Under the agreement to acquire MARSS, as noted above tranche 1 of the earn-out was completed during the quarter, with the vendors electing to receive €23.9m in EOS shares at a value of €4.25 (A$7.40), or approximately 5.6m EOS shares. The relevant shares are expected to be issued to the vendors in the coming weeks and are subject to the usual restrictions under the EOS’s Securities Trading Policy. Further shares may be earned by the MARSS vendors in tranche 2 and tranche 3 of the earn-out. Full details of the earn-out were announced on 15 May 2026. RELATED PARTY TRANSACTIONS Payments to related parties of the entity and their associates totalled $472,321 for the quarter. These amounts include: → payments of $175,654 paid to the Managing Director & CEO, Dr Schwer, representing salary paid during the quarter; and → $296,667 paid in directors’ fees and superannuation to non-executive directors and entities associated with non-executive directors during the quarter. ASX Listing Rules Appendix 4C (17/07/20) + See chapter 19 of the ASX Listing Rules for defined terms. Page 6 OTHER MATTERS → As part of its contracts to supply a customer in the Middle East, the Group is obligated to contribute to economic development in the country as an offset against purchases of its products and services. Full details are included in the Half Year Financial Report for the half-year ended 30 June 2026 (lodged on 25 August 2026). During the quarter, in accordance with the relevant approvals from the offset authority, EOS continued to progress the formal establishment of a JV entity with Shielders Advanced Industries that is intended to generate offset credits once operational. EOS has until 1 July 2033 to generate the required offset credits. EOS considers that it is currently in compliance with its obligations. → As previously announced, during June 2026 ASIC commenced an investigation in connection with the contract between EOS and Goldrone and the announcements of 15 December 2025, 10 February 2026 and 12 March 2026. The Company is continuing to cooperate with ASIC. This announcement has been authorised for release to the ASX by the Board of Directors. All amounts are in Australian dollars unless stated.

The costs of this facility are included in Item 1.5 as other costs of finance paid. • Under the terms of certain Defence Systems contracts, the Group has an offset agreement with the relevant overseas Government Authority for an amount of US$17.5m (A$25.2m). The offset bond was provided by Export Finance Australia under the bond facility agreement noted above and is secured by cash security deposit of US$17.5m (A$25.2m) and a fixed and floating charge over the assets of the Group. The costs of the offset bond are included in Item 1.5 as other costs of finance paid. • The Group continues to be required to comply with covenants under facility agreements with Export Finance Australia, including guarantee facilities. The Group complied with these requirements during the quarter and at the date of this announcement. Other Facilities • On 14 January 2026, the Group entered into an agreement with Westpac Banking Corporation (‘Westpac”) to issue a A$10.8m bank guarantee to a customer in Australia. The bank guarantee was fully secured by cash deposits. The guarantee amount, together with the required cash security, is expected to reduce progressively in future as key contractual milestones are achieved during the contract period. • As previously announced, under the terms of a Defence Systems contract, the Group is required to provide a repayment bond of varying amounts up to €21m (A$30m), during the contract to cover funds received in advance from the customer. At 30 September 2026, a repayment bond of €10.5m (A$17.0m), was in place with Westpac and was fully secured by cash deposits. The bond value reduces progressively as key contract milestones are achieved during the contract period. • On 12 August 2026, the Group provided a performance bond guarantee of £37.1m (A$70.4m) with Westpac to a prospective government customer in the Middle East in connection with a proposed new contract. The guarantee is secured by a cash security deposit of £40.3m (A$76.5m). The related contract was subsequently signed on 9 October 2026 and remains subject to certain conditions before performance can commence. • On 2 March 2026, EOS announced that it had finalised a $100m two-year secured term loan facility with Washington H. Soul Pattinson and Company Limited (“Soul Patts”). On 15 May 2026, EOS drew down $70m from this $100m facility. At 30 September 2026, and as at the date of this report, a further $30m remains available for drawdown until 28 November 2026 under the facility.
