Tetra Tech Acquires Canadian Consulting and Engineering Firm BPR

PASADENA, Calif.--(BUSINESS WIRE)-- Tetra Tech, Inc. (NASDAQ: TTEK) announced today that it has acquired BPR, a scientific and engineering services firm with more than 1,600 employees principally based in Quebec. BPR provides multidisciplinary consulting and engineering support for water, energy, industrial plants, buildings, and infrastructure projects. BPR generated approximately US$170 million in revenue over the past 12 months, and is currently expected to contribute approximately 3 to 5 cents to fiscal year 2011 diluted EPS. The terms of the acquisition were not disclosed.

“We welcome all of the employees of BPR to Tetra Tech,” said Dan Batrack, Tetra Tech’s Chairman and CEO. “Like Tetra Tech, BPR leads with science and focuses on complex water-related projects. With the addition of BPR in eastern Canada, Tetra Tech now offers its Canadian clients complete coast to coast coverage. BPR has no geographic overlap with existing operations.”

This transaction is Tetra Tech's third major acquisition in Canada, following the acquisition of EBA Engineering Consultants in August 2010 and Wardrop Engineering in January 2009. Tetra Tech now has about 3,500 employees working in Canada, and approximately 25% of the Company’s fiscal year 2011 net revenue is expected to be generated from international operations.

Concurrently, Tetra Tech has renamed its former Environmental Consulting Services segment the Engineering and Consulting Services segment. BPR will join this segment, which focuses on front-end services.
