Tetra Tech to Acquire Australian Mining Services Firm Proteus

PASADENA, Calif.--()--Tetra Tech, Inc. (NASDAQ: TTEK) announced today that it has entered into a definitive agreement to acquire substantially all of the assets of mining engineering company Proteus EPCM Engineers of Perth, Australia. Proteus has about 150 employees primarily located in Western Australia and has annual revenue of approximately $30 million. The acquisition is expected to close in early August 2011.

“This is an important step in the execution of Tetra Tech’s global expansion strategy,” said Dan Batrack, Tetra Tech’s Chairman and CEO. “Like Canada, Australia’s high-growth economy is driven by strong demand for natural resources. This acquisition will serve as a gateway to new markets across Asia and Africa. We plan to continue expanding our service offerings in Australia in each of Tetra Tech’s core markets.”

An established regional player in Western Australia, Proteus has provided engineering services to the mining and minerals processing sector for more than 25 years. Proteus has experience in a wide range of commodities, particularly iron ore, precious and base metals, gold, mineral sands, and aluminum. They generally act as the owner’s engineer, designing facilities and providing procurement and construction management services. Proteus will expand Tetra Tech’s technical capability and bring new expertise in iron ore and bulk handling. Proteus is joining Tetra Tech’s Engineering and Consulting Services segment.
