ITM growth strategy CONTRACT MINING COAL TRADING Growing internal contribution Blending for value-added Focusing on growing organically. Leveraging ITM’s extensive Currently conducting a further network to enable this asset- study to increase capacity to light strategy. work at Melak cluster. COAL MINING Organic and inorganic growth  77 Mt from drilling and exploration  4.5 Mt from TIS acquisition Evaluating more opportunities  FUEL PROCUREMENT POWER GENERATION Cost control and additional margin Conventional and renewables ITM’s fuel business initial focus Focusing on renewable energy, has been on supplying internal such as solar PV, hydro, etc. consumption. Going forward, will also build capacity to grow 3 rd party sales. 6

Organic growth provides additional reserves at a relatively attractive price SIMPLIFIED AND ILLUSTRATIVE Drilling boundary • Current reported reserves/resources OB are based on current exploration • Does not include potential reserves, which could be proven by doing more exploration Exploration • More exploration can confirm and identify more resources/reserves 77 Mt • Also increases optionality to convert more resources into reserves additional reserves • $7-8 M p.a. drilling and exploration capex • Options to increase reserves with updated economics, technology Optimization • Productivity, efficiency, and Optimization additional margins along the value chain would also lead to better economics and in turn, more reserves 7
