Magma Energy - Strategy & Value Creation

Magma’s strategy: broad asset portfolio and scale = “discovery returns” and “utility returns” Reduces drilling risk and high front-end capital risk Improves margins with lower cost of capital Better multiples Better multiples

Portfolio acquisition & discovery highlights: Nevada: 13.5 MW power plant with 47.5 MW

expansion potentialp p Iceland: 98.5% interest in HS Orka’s 2 power plants

producing 175 MW with 230 MW expansion potential Chile: discovery of 320 MW Inferred Resource Plus a further 21 early stage and 4 advanced stage projects

We are a power company and an energy asset holder

Income growth and sub-surface capital asset growth

Geothermal power can be the lowest cost and cleanest form of electricity generation Potentially a great cash generator without incentives Incentives (USA Europe Chile) greatly improve margins Incentives (USA, Europe, Chile) greatly improve margins
