Announcement PDF ADX Energy Ltd (ASX:ADX) ASX RELEASE Page | 1 ADX Energy Ltd | ABN 50 009 058 646 -Registered and Principal Office Australia Level 1, 168 Stirling, Nedlands WA 6009, Australia Telephone: +61 8 9381 4266 | admin@adxenergy.com.au | adxenergy.com.au 6 November 2026 Commencement of Austrian Well Work Vienna Basin production enhancement and HOCH-1 Gas production testing program “Production well work targeting a 100 BOEPD of incremental production from ADX’ Vienna Basin Fields and Phase 2 testing of the HOCH-1 gas discovery” ADX Energy Ltd (ASX Code: ADX) is pleased to advise the commencement of a work program utilising the MB Well Services workover rig. The program will focus on production enhancement activities across ADX’ 100% owned Vienna Basin Fields, as well as the testing of the HOCH-1 gas discovery well within the ADX-AT-I exploration licence in Upper Austria. ADX is the operator and holds a 50% economic interest in the HOCH gas discovery. Figure 3 below shows the location of the Vienna Basin Fields and the ADX-AT-I and ADX-AT-II exploration licences. The work program described below is expected to have a duration of approximately eight (8) weeks. ADX will provide work program results as they become available. Well Work Program Activities The program of well work activities and is scheduled as follows: 1. Vienna Basin well: new gas zone completion Week Commencing 9 November 2. Vienna Basin oil well: pump replacement Week Commencing 16 November 3. HOCH-1: Phase 2 gas testing Week Commencing 7 December 1 4. Vienna Basin well: new oil zone completion Week Commencing 14 December 1 Approximately two weeks of well work required at HOCH-1 prior to testing Work Program Objectives The well work program objectives are summarised as follows: 1. The perforation of a gas zone and the recompletion of the GA-093 production well to a gas well is expected to deliver approx. 50 to 60 BOEPD of incremental gas production. Undertaking the work at this time is expected to generate elevated incremental cash flow due to high gas prices and strong gas demand during winter months. The current gas price in Europe is EUR 86 per MWh which is equivalent to an oil price of US$ 170 per barrel. 2. The replacement of a down-hole pump in the GA-072A production well is expected to deliver approx. 15 BOEPD of incremental oil and gas production. 3. The testing of the HOCH-1 Hall Channel Zone #6 reservoir, refer to figure 2, requires the removal of the well current completion, the drilling out of a cement plug to access deeper gas reservoirs and re-running a production completion prior to perforating the well2 . 4. The perforation of a new production interval in the GA-087 well and the installation of a sand retention completion is expected to deliver approx. 30 to 40 BOPD of incremental oil production. 2 The HOCH-1 shallow gas discovery well encountered up to eight (8) biogenic gas reservoirs within the Hall basin floor fan formation and the Base Hall Channel formation. The commingled flow rate from four (4) reservoirs during Phase 1 testing was 3.15 MMCFPD which is equivalent to 548 BOEPD (refer to ASX release on 28 August 2026).

The zones have been mapped and correlated to nearby gas discoveries, indicating the potential for a large lateral extension and resource potential. This interpretation is further supported by reserves data from nearby Hall Channel production wells.
