Strategic positioning and market environment

• Malaysia offers prolific hydrocarbon basins, strong data access, and a supportive regulatory environment, attracting major industry players and enabling agile, smaller companies to capitalize on overlooked opportunities.

• Gas demand in Malaysia is high, with shortages in Sarawak and Peninsular Malaysia driving the need for rapid exploration and development.

• Malaysian portfolio leverages prolific basins and strong partnerships, including Petronas and INPEX, with entry as operator in 2024 targeting significant growth and regional gas demand.

• Over 200 undeveloped offshore fields and ~10 billion boe of stranded resources exist in Malaysia, supported by extensive seismic and geological data coverage.

• The company leverages its agility and close relationships with regulators to act quickly on opportunities, unlike larger competitors.

Portfolio overview and asset highlights

• The portfolio centers on three key assets: Temaris (Malay Basin, 100% op), Dewa (Sarawak Basin, 28%), and Block 2A (Sarawak Basin, 10%), all located in highly prospective regions.

• Temaris is the flagship asset, acquired in June, with rapid progress from bid to evaluation, and significant upside potential identified.

• Dewa comprises a collection of 12 previously overlooked shallow water gas fields, now maturing well with strong reservoir quality and production potential.

• Block 2A contains the Kertang prospect, one of the largest undrilled structures in Malaysia, with significant follow-on potential in adjacent plays.

• Certified 2C resources total 63 mmboe, with 281 mmboe of prospective resources and a market cap of approximately £50 million, with £9 million cash and no debt as of October 2025.

Temaris cluster: development and exploration

• Temaris cluster holds 276 bcf discovered gas and significant exploration upside, with Tembakau and Mengkuang fields as initial development focus.

• Multiple stacked pay zones and straightforward seismic interpretation support further prospectivity, including Allamanda, Keladi, and Kangkung prospects, with potential for a ~1 TCF gas hub.
