Announcement PDF 29 October 2026 SEPTEMBER 2026 QUARTERLY ACTIVITIES REPORT AND APPENDIX 4C 4DS Memory Limited (ASX:4DS) ("4DS" or "the Company") is pleased to provide its Quarterly Activities Report and Appendix 4C for the quarter ended 30 September 2026. Highlights • Completed the acquisition of Jenesys Pty Ltd on 9 October 2026, adding edge-AI and autonomous systems software to 4DS's ReRAM technology. • 4DS ReRAM development continues as a core program, now focused on an analogue in-memory computing (AIMC) roadmap based on the 4DS PCMO ReRAM cell. • Jaspal Sarai appointed Managing Director and CEO on completion. • Cash at 30 September 2026 of A$6.6 million. • A$2.0 million raised through the placement. • Jenesys technology is being marketed into defence and commercial robotics opportunities. • Team strengthened with a Business Development and Alliance Manager, a Mechatronics Engineer and the first member of a new Advisory Board. ACQUISITION OF JENESYS Shareholders approved the acquisition of Jenesys at the General Meeting on 2 October 2026, and the transaction completed on 9 October 2026. Jenesys develops edge-AI software that lets fleets of autonomous systems coordinate and make decisions on the device, without a central controller, including in environments where GPS and communications are denied or disrupted. The acquisition brings together two programs of equal importance to the Company: 4DS's PCMO ReRAM memory technology and Jenesys's edge-AI software. Development of the 4DS ReRAM cell continues, now directed at analogue in-memory computing (AIMC). ReRAM: ANALOGUE IN-MEMORY COMPUTING The 4DS ReRAM technology is at the memory cell stage. Its analogue properties make the PCMO cell well suited to AIMC research. Development of the 4DS ReRAM technology remains a core part of the Company's strategy. The Company is finalising the engagement to develop a roadmap for building a test environment where Jenesys neural networks can be ported to an AIMC setup and benchmarked against industry-leading chipsets. Because Jenesys develops its own neural networks, the Company can test the 4DS cell on real AI workloads rather than relying on third parties. The Company will inform the market when arrangements are finalised. FUNDING AND RUNWAY The Company raised A$2.0 million (before costs) through the placement to professional and sophisticated investors at A$0.01 per share. The A$3.0 million entitlement offer closed on 28 September 2026 and only A$155,689 worth of entitlements was taken up. The Board does not plan to place the shortfall under the rights issue. Cash at 30 September 2026 was A$6.6 million (not including the $2m raised). The Board has reviewed planned expenditure following the entitlement result and prioritised the ReRAM AIMC program, Jenesys platform engineering and business development. On the current budget, the Board believes the Company has sufficient funds to carry out its strategy for up to 18 months. JASPAL SARAI APPOINTED MANAGING DIRECTOR AND CEO Mr Sarai is the founder and CEO of Jenesys. From 2022 to November 2025 he was the founding investor in, and a strategic adviser to, Akula Tech, an Australian space and defence technology company, working on its strategy, partnerships and commercial engagement. Akula ran a drone- swarm research project with UNSW, supported by Defence Trailblazer, and launched Nexus-01, an AI-enabled hyperspectral satellite, in August 2025. He has more than 25 years’ experience building technology businesses and delivering innovative IT solutions. Since 2009 he has led Source Central Partners, a Melbourne-based provider of managed IT services, cyber security and application development to the retail, transport, education and government sectors across Australia and New Zealand. In 2014 he founded Jaarvis, a technology innovation business with teams in Australia, India and Hong Kong that develops new products for startups and global enterprises. Through the Jaarvis Accelerator in India, he also mentored and seed-funded early-stage IoT and fintech companies. DEFENCE AND COMMERCIAL OPPORTUNITIES Since completion, the Company has been actively presenting and proposing Jenesys technology to prospective customers in defence and commercial markets. In plain terms, Jenesys software lets robots, drones and sensors share what they see, divide up the work and decide what to do on the spot, without waiting on a central computer or a network connection. No binding agreements have been entered into as at the date of this report. The opportunities below describe the markets and the ways the technology could be used. They are not a forecast of revenue. The Company will inform the market of any material agreement in line with its continuous disclosure obligations. 1. Defence: drones, sensors and high-altitude platforms Defence forces are deploying more drones and sensors than people can watch. Jenesys is proposing: • autonomous edge-AI for UAVs and drones, so groups of drones can search an area, share the work and keep going when GPS or communications are jammed • an autonomous AI layer to orchestrate multi-sensor defence systems, combining feeds from cameras, radars, drones and high-altitude platforms (HAPS) into one picture, and either alerting an operator or, where it has been given permission, acting itself Scenario: protecting critical infrastructure. The Company is putting together a solution to detect and counter attacks by drones and missiles on sites such as oil refineries. Several types of sensors watch the airspace around the site. The Jenesys edge-AI layer combines what they see and assesses each threat in real time. It then either advises an operator, who authorises the response, or, where permitted, takes the required action itself. The software can run on HAPS and on the site’s own infrastructure, making fast decisions on the spot. Kingdom of Saudi Arabia (KSA). Jenesys is engaged on defence opportunities in KSA, proposing its edge-AI software stack for detection and surveillance, including integration with sensors, drones and HAPS. KSA was the world's eighth-largest military spender in 2025, at an estimated US$83.2 billion (SIPRI). It aims to localise more than 50% of its military spending by 2030, up from 24.8% (GAMI, via The Defense Post). The Company is also exploring opportunities in other countries. Australia. The Government plans up to A$22 billion of investment in drone, counter-drone and autonomous systems over the next decade under the 2026 Integrated Investment Program (Australian Aviation). The market figures in this section are third-party estimates of total market size. They are shown for context only. The Company does not expect to address these markets in full. The Company attended Land Forces 2026 in Perth from 6 to 8 October 2026, meeting defence, government and industry participants. Jenesys has applied for membership of the Defence Industry Security Program (DISP) and is progressing through its requirements. Jenesys owns the rights to the technology and programs developed by Akula Tech. It is re- engaging with a number of initiatives that Akula Tech started but could not complete because of funding constraints and Akula Tech's later liquidation. The Company will report on these as they progress. 2. Drone footage and data analysis Drones collect hours of video when inspecting sites, crops, infrastructure or disaster areas. Someone usually has to watch it later. Jenesys edge-AI can analyse the footage on the drone or at the site and pick out what matters, such as damage, a change or an object of interest. The customer gets answers, not hours of raw video. Independent estimates of the drone analytics market vary widely. One puts it at US$15.0 billion in 2024, rising to US$50.0 billion by 2030 (Grand View Research). 3. Cleaning and facilities management robots Large buildings and supermarkets increasingly use robot cleaners. Most work alone, following a fixed route. With Jenesys software, a fleet of robots can work as a team: • splitting a large floor between them so it's cleaned faster • sending the nearest free robot to a spill as soon as it's reported • calling lifts and opening doors on their own to move between floors Jenesys is working on integrating and testing its swarming software with robot hardware, including lifts and building system APIs. Independent research estimates the global market for commercial surface cleaning robots at US$1.45 billion in 2026, growing to US$2.71 billion by 2030 (The Business Research Company). TEAM AND CAPABILITY The Company has started building its team to accelerate technical and business development. • Zachary Delaney, Business Development and Alliance Manager (joined 12 October 2026). Zachary served for six and a half years (2018 to 2025) in the Royal Australian Air Force as an Air Intelligence Analyst in operational intelligence, preparing threat assessments and reports for senior leadership. He then spent a year in defence business development at Akula Tech, building partnerships with industry stakeholders. He studied at the University of Wollongong. • Zain Ali Agharia, Mechatronics Engineer. Zain was previously a Software Engineer at Akula Tech (2024 to 2026) and a Mechatronics Engineer at Currawong Engineering. His earlier work includes sensor fusion and autonomous driving software at Applied EV, and robotics research and teaching in engineering, including intelligent robotics, at Monash University. At Jenesys, he is focused on integrating Jenesys edge-AI into commercial robotic products to add autonomous functions. • Jagmohan Singh, Consultant and Advisory Board member. Jagmohan is a retired Colonel who served for 23 years (1982 to 2005) with the Indian Defence Services, including at Integrated Headquarters of the Ministry of Defence, where he worked on defence equipment requirements, procurement and evaluation. He then spent more than 17 years at Lockheed Martin (2006 to 2023), most recently as Regional Director India and South Asia. There he supported programs with India's Ministry of Defence and armed services, including the C-130J aircraft and MH-60R helicopter, and built partnerships with Indian industry. He now consults on aerospace and defence. PLANS AND OBJECTIVES The Company's objective is to turn the Jenesys platform into recurring software revenue across defence and commercial markets, and to advance the 4DS ReRAM cell for AIMC. Both programs carry equal weight in the Company's strategy. Its plans for the next four quarters are set out below.
