Geo Energy 29 Scenario analysis inputs Scope Covers the impacts of climate change on Geo Energy’s four mining assets: Sungai Danau Jaya (SDJ), Tanah Bumbu Resources (TBR), Bumi Enggang Khatulistiwa (BEK) and Surya Tambang Tolindo (STT). Transition scenarios Alternative case – Announced Pledges Scenario (APS) Base Case: IEA Stated Policies (STEPS) This scenario assumes that all climate commitments made by governments, ranging from Nationally Determined Contributions (NDCs) to longer-term net zero targets, will be achieved. The APS gets close to achieving the goal of the Paris Agreement to limit the temperature rise to “well below 2°C”. This scenario assumes a “business-as-usual” pathway towards 2050, exploring the implementation of existing and announced policies. It does not consider additional policy implementation. Physical scenarios Baseline: Based on historical data at Geo Energy’s asset locations Low Carbon: IPCC SSP1-2.6 High Carbon: IPCC SSP5-8.5 This scenario assumes that global CO2 emissions are cut quickly, reaching net-zero after 2050. There is a socioeconomic shift towards sustainability but temperatures will still rise to 1.8°C by 2100 Demonstrates the worst-case scenario where no measures are taken to combat climate change resulting in CO2 emissions doubling by 2050 and average temperatures rising by 4.4°C by 2100. Near-term (2030) Temperature 1.5 °C Mid-term (2050) Temperature 1.7 °C Long-term (2100) Temperature 1.8 °C Near-term (2030) Temperature 1.5 °C Mid-term (2050) Temperature 2.4 °C Long-term (2100) Temperature 4.4 °C Time horizons • Mid-term: 5-10 years and represented by 2030 • Long-term: over 10 years and represented by 2050 Qualitative Identification of business implications on Geo Energy Step 3 Evaluation of climate-related transition drivers for the Group's portfolio under different climate scenarios Step 2 Identification of relevant transition risks and opportunities drivers for Geo Energy from peer analysis, industry/sector-specific research papers and internal data Step 1 Transition scenario analysis The transition scenario analysis aims to assess our exposure to potential impacts arising from a global transition to a low carbon economy. Key transition drivers (risks and opportunities) were identified based on its relevancy to the Group through a combination of peer benchmarking, industry/ sector-specific information, and internal data. The analysis utilises a three- step qualitative process as highlighted on the right.
