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 11 November 2026 Austrian Well Work Program Yields Immediate Success Vienna Basin well flows at an initial rate of 1.8 MMSCFPD1 . The well will be choked back to 0.6 MMSCFPD due to sales pipeline capacity constraints. “The restricted rate of 0.6 MMSCFPD is equivalent to a 100 BOEPD2 . European gas price is EUR 82.6 per MWh which is equivalent to US$162 per barrel.” ADX Energy Ltd (ASX Code: ADX) is pleased to advise the commencement of a well work program utilising the MB Well Services workover rig has yielded immediate success at ADX’ 100% owned Vienna Basin Fields. The GA-093 production well has flowed at an initial rate of 1.8 MMSCFPD through an 8mm choke after its recompletion and the perforation of a gas zone. The well will be restricted to a sales gas rate 0.6 MMSCFPD which is equivalent to an oil rate 100 BOEPD. Undertaking the work at this time will generate elevated incremental cash flow due to high gas prices and strong gas demand during winter months in Europe. The current gas price in Europe is EUR 82.6 per MWh which is equivalent to an oil price of US$162 per barrel. The incremental production from the well represents approximately a 40% increase to ADX Austrian production which averaged 242 BOEPD during the quarter ending 30 September 2026. The ongoing well work program will focus on production enhancement activities at ADX’ 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 Upper Austrian ADX-AT-I and ADX-AT-II exploration licences. Future Well Work Program Activities The remaining program of well work activities is scheduled as follows: 1. Vienna Basin oil well pump replacement Week Commencing 16 November 2. HOCH-1 well Phase 2 gas testing Week Commencing 7 December3 3. Vienna Basin well new oil zone completion Week Commencing 14 December Future Work Program Objectives The remaining well work program objectives are summarised as follows: 1. 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. 1 MMSCFPD means Million Standard Cubic Feet Per Day 2 BOEPD means Barrels of Oil Equivalent Per Day 3 Approximately two weeks of well work is required at HOCH-1 prior to testing ADX Energy Ltd (ASX:ADX) ASX RELEASE Page | 2 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 2. The testing of the HOCH-1 Hall Channel Zone #6 reservoir, refer to figure 2, requires the removal of the well’s current completion, the drilling out of a cement plug to access the deeper gas reservoir and re-running a production completion prior to perforating the well4 . 3. 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. Figure 1: The MB well services AW24 rig at the GA-93 well at ADX’ Vienna Basin Fields 4 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) ADX Energy Ltd (ASX:ADX) ASX RELEASE Page | 3 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 HOCH-1 Phase 2 Testing Objectives The Phase 2 testing program will evaluate the slightly deeper Hall Channel zones only (refer to figure 2). 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. Figure 2: Shows the post drill mapping and the well correlations that indicate a large extension of the stratigraphic trap (at least 2.5 km to the SE) Figure 3: ADX exploration licences and producing fields in Austria ADX Energy Ltd (ASX:ADX) ASX RELEASE Page | 4 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 Further Well Work Program and Testing Results Further updates regarding the Vienna Basin production enhancement program and the HOCH-1 well testing program and will be provided as they become available.
