The ADX net Austrian production (including the Anshof Field in Upper Austria) has increased to approximately 285 BOEPD (+35%).  Additional Vienna basin oil and gas production is highly desirable due to:  Low incremental operating costs.  Less than 1% royalty,  Brent equivalent oil pricing, and  Central European Gas Hub gas pricing (currently approx. EUR48/ MWh or US$16.5 per MMBTU). ADX Executive Chairman, Mr Ian Tchacos, said “The 35% increase in net Austrian production from the recent well work at our Vienna Basin fields is a positive outcome with further production growth identified from future work programs. Our local technical and operations team are evaluating further production enhancement opportunities including infill drilling and further behind pipe potential to increase production and reserves from the fields. “We are planning a potential new development well and an appraisal well to be drilled in 2027. New wells on the field can be tied into infrastructure immediately at minimal cost thereby enhancing cash flow and economic returns” 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 Production operations at ADX’ Gaiselberg and Zistersdorf fields ADX Energy Ltd (ASX Code: ADX) is pleased to advise that a program of behind pipe perforation on two existing production wells has resulted in additional Vienna Basin field oil and gas production of approximately 75 BOEPD. ADX holds a 100% equity interest in the Vienna Basin Fields located in Lower Austria, approximately 70km northeast of Vienna. The GA-10A well and GA-93 well behind pipe perforation program has resulted in additional production of 24 BOPD oil and 52 BOEPD (gas) respectively. The behind pipe perforation work has increased Vienna Basin field production from approx.150 BOEPD to 220 BOEPD, thereby increasing ADX net Austrian production (including the Anshof Field in Upper Austria) by 35% to approximately 285 BOEPD. ADX has commenced a program of behind pipe perforation of existing wells to improve field production and enhance profitability. ADX is also planning a program of infill and appraisal drilling to start in 2027 to further increase production and reserves from the two Vienna Basin fields called Zistersdorf and Gaiselberg. Additional Vienna basin production is highly desirable due to low incremental operating costs, less than 1% royalty, Brent equivalent oil pricing and Central European Gas Hub gas pricing (currently approx. EUR48 / MWh or US$16.5 per MMBTU). Vienna Basin Fields Summary  A multilayer field also suitable for gas and H2 storage  Eighteen active wells and liquid processing capacity above 4000 BPD  Low emission, low decline production delivering long term cash flow.  Ownership of 13.7 hectares of land which could be used for the development of a solar park.  High value sweet crude oil, very favourable fiscal terms (less than 1% royalties)  Connected by pipeline to the OMV refinery near Vienna and the local gas grid For further details please contact: Ian Tchacos Executive Chairman +61 (08) 9381 4266 ian.tchacos@adxenergy.com.au Authorised for lodgement by Ian Tchacos, Executive Chairman 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 Persons compiling information about Hydrocarbons: Pursuant to the requirements of the ASX Listing Rule 5.41 and 5.42 the technical and reserves information relating to Austria contained in this release has been reviewed by Paul Fink as part of the due diligence process on behalf of ADX.
