2. Caution Regarding Forward-Looking Statements
These slides and the accompanying oral presentation contain certain “forward-looking information” within the meaning of Canadian
securities laws, which may include, but is not limited to, statements with respect to future events or future performance,
management’s expectations regarding our growth, results of operations, estimated future revenues, requirements for additional
capital, production costs and revenue, future demand for and prices of electricity, business prospects, opportunities and estimates of
recoverable geothermal energy “resources” or “reserves” or energy generation capacities (at either P90 or based on the Geothermal
Code for Public Reporting) Such forward looking information reflects management’s current beliefs and is based on information
Reporting). forward-looking management s
currently available to management.
A number of known and unknown risks, uncertainties and other factors, may cause our actual results or performance to materially
differ from any future results or performance expressed or implied by the forward-looking information. Such factors include, among
others, those discussed in the section of our prospectus entitled “Risk Factors”. These factors should be considered carefully. The
forward-looking information is also based upon what management believes to be reasonable assumptions, including, but not limited
g p g p g
to, assumptions about: the success and timely completion of planned exploration and expansion programs, including expansion and
improvements to operations in Iceland and to our Soda Lake Operation in Nevada; the growth rate in net electricity consumption;
support and demand for non-hydroelectric renewables; government initiatives to support the development of renewable energy
generation; the accuracy of resource and reserve estimation methodology and probabilistic analysis used to estimate the quantity of
potentially recoverable energy; geological, geophysical, geochemical and other conditions at our properties; the reliability of technical
data, including extrapolated temperature gradient, geophysical and geochemical surveys and geothermometer calculations; capital
expenditure estimates; availability of capital to fund exploration development and expansion programs; the differences in financial
exploration,
results reported under IFRS and Canadian GAAP; and general economic conditions. Forward-looking information and statements
are also based upon the assumption that none of the identified risk factors that could cause actual results to differ materially from the
forward-looking information and statements will occur.
There can be no assurance that the forward-looking information will prove to be accurate, as actual results and future events could
differ materially from those anticipated in such information. Accordingly, prospective investors should not place undue reliance on
y p g y, p p p
forward-looking information. Other than as required by applicable securities laws, we assume no obligation to update or revise such
forward-looking information to reflect new events or circumstances.

3. Geothermal - What is it?
Geothermal is a proven, global, underexploited, base-load, renewable energy source
Literally heat from the earth, derived from deep natural magma (molten rock)
Requires Heat, Permeability and Water

4. 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
Portfolio acquisition & discovery highlights:
 Nevada: 13.5 MW power plant with 47.5 MW
expansion potential
p 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
