NOTE 9 — BUSINESS SEGMENTS

The Company has three reporting segments: the Electricity segment, the Product segment and the Energy Storage segment. These segments are managed and reported separately as each offers different products and serves different markets.

• Under the Electricity segment, the Company builds, owns and operates geothermal, solar PV and recovered energy-based ("REG") power plants in the United States and geothermal power plants in foreign countries, and sells the electricity generated by those power plants.

• Under the Product segment, the Company designs, manufactures and sells equipment for geothermal and recovered energy-based electricity generation and remote power units and provides services relating to the engineering, procurement and construction ("EPC") of geothermal and recovered energy-based power plants.

• Under the Energy Storage segment, the Company provides energy storage and related services as well as services relating to the engineering, procurement, construction, operation and maintenance of energy storage units.

Transfer prices between the operating segments are determined based on current market values or cost-plus markup of the seller’s business segment.
