3D Energi (TDO) Investor presentation summary

Investment highlights

• Multi-well offshore exploration campaign in 2025 targets low-risk, seismic-supported gas traps in a supply-constrained market.

• Positioned to deliver new gas supply to Victoria as legacy fields decline, with proximity to infrastructure for rapid development.

• Early-stage valuation offers high leverage to success, with significant upside potential on gas discovery.

• Attractive farm-in deal with ConocoPhillips provides ~$100m carry for two low-risk exploration wells.

• Robust portfolio of 51 mapped prospects supported by 3D seismic, ranked by scale and development potential.

Strategic positioning and market context

• Otway Basin is a key exploration hotspot with renewed interest from majors and NOCs, including ConocoPhillips and KNOC.

• Existing pipelines and processing capacity, plus supportive government stance, enable faster, cost-effective development.

• Projected gas supply shortfalls in Victoria from 2025 onward create a strong demand outlook for new discoveries.

• Otway gas is more cost-effective, reliable, and less emissions-intensive than QLD supply or LNG imports.

Project portfolio and resource base

• Holds exposure to the largest undeveloped gas inventory in the Otway Basin: 51 prospects, 9.2 Tcf mean prospective resource (gross), 1.8 Tcf net.

• Portfolio spans two permits (VIC/P79 and T/49P) and is grouped into six clusters for scalable development.

• Charlemont Cluster is drill-ready with ~1 Tcf mean prospective resource (gross), adjacent to infrastructure.

• Regia Cluster contains 13 emerging leads with 1.4 Tcf mean prospective resource (gross); new 3D seismic survey planned.

• Southern clusters like Flanagan and Whistler Point offer frontier-scale upside and long-term growth.
