ADX Energy Ltd (ASX: ADX, "ADX" or "the Company") is pleased to provide an update on its activities for the quarter ended 30 September 2025.

** Excludes restricted funds secured for bonds and guarantees totalling A$ 1.3 million

Past Quarter Highlights

• Land secured, drilling and environmental permitting for three Shallow Gas Prospects (HOCH, GOLD and SCHOE) drilling in February 2026. Ongoing maturation of over 6 follow up shallow gas prospects.
• Discussions with potential farmin parties for funding ADX' 100% interest ADX-AT-II GOLD Area cluster.
• Welchau-1 Environmental Clearance objection overturned by Courts - flow testing in January 2026.
• Welchau Deep prospect generation – 125 BCF Mean prospective Estimate Resource*** (refer Schedule 1).
• Formal award of Sicily Channel Gas Exploration Permit, Offshore Italy - 369 BCF Best Estimate Prospective Resource*** (Refer ASX Release Dated 30.8.2022)
• Commitment to purchase of Anshof Permanent Production Facility - 3,000 barrel per day processing capacity.
• Upper Austria Prospect Inventory Update - 374 BCF Gas and 31 MMBLs Oil Mean Estimate Prospective Resource*** (refer Schedule 1).
• Settlement of 20% interest in Anshof Field Area purchased in exchange for partners outstanding debt.

*** Cautionary Statement: Prospective Resources are those estimated quantities of petroleum that may potentially be recovered by the application of a future development project(s) relate to undiscovered accumulations. These estimates have both a risk of discovery and a risk of development. Further exploration appraisal and evaluation is required to determine the existence of a significant quantity of potentially recoverable hydrocarbons.

Next Quarter Planned Activities

• Investigate and prepare for a potential dual listing on Oslo Børs' Euronext Growth market.
  • Trading access for European investors, enhanced visibility, improved liquidity, broaden shareholder base and support future growth opportunities.
• Finalise preparations for 2026 Upper Austria testing and drilling work program.
• Ongoing maturation of new shallow gas prospect generation in 100% equity held ADX-AT-I licence area.
• Conclude farmout transaction for funding ADX' 100% interest in the ADX-AT-II GOLD Area cluster.
• Mature Anshof Near Field Oil prospects and Jurassic aged oil and gas plays utilising reprocessed 3D Seismic.
• Italy resources review incorporating additional licence data as well as new data from nearby analogous fields.

ADX Executive Chairman, Mr Ian Tchacos, said "During the past quarter ADX has assembled an outstanding opportunity for organic growth based on low-risk shallow gas targets capable of providing multiples of production growth in a short period of time as well as a near field appraisal well. What stands out about the program is its low-risk nature and the ability to efficiently and economically develop both gas and oil discoveries. The following graphic illustrates the potential build up production from the 2026 work program."
"Success with the initial shallow gas play program can be followed up with an additional 6 (six) shallow gas targets exhibiting similar seismic characteristics.

"The decision by the Upper Austrian State Administrative Court to overturn the Welchau environmental objections is very positive. It is not only important for the resumption testing at Welchau as well as potential future operations to explore the Welchau -Deep prospect, it is an important indication of the ongoing support for gas exploration due to the strong public interest for securing clean domestic natural gas resources in Austria.

"While the operational focus in the near term is on Upper Austria, our new Offshore Sicily Channel permit is a potentially transformational asset in a predictable geological setting. The permit's potential is validated by historic data in the permit as well as nearby analogous gas fields at Lippone Mazarra and Argo Cassiopeia. The economic potential of any discovery in the permit is enhanced by highly productive reservoirs, shallow water and drill depths, nearby infrastructure, low royalty rates and strong gas pricing.

"We expect a positive revision of prospective resource estimates for Sicily Channel permit in the coming quarter incorporating additional data from within our permit and the surrounding analogous gas fields."
