Bronstein, Gewirtz & Grossman, LLC Announces Investigation of Tetra Tech, Inc.

Bronstein, Gewirtz & Grossman, LLC is investigating potential claims on behalf of purchasers of the securities of Tetra Tech, Inc. ("Tetra" or the "Company")

. The investigation focuses on whether the Company and its executives violated federal securities laws. On June 19, 2013, shares of Tetra fell $3.60 or 13% in early market trading after the Company announced an update of its third quarter 2013 outlook to reflect increased restructuring costs resulting from the previously announced weakness in Eastern Canada and mining, and new findings on certain project claims. The Company will take a loss in the fiscal third quarter as it absorbs about $95 million in charges. The charges will affect the revenue and profitability of all three reportable segments. In the third quarter, revenue, net of subcontractor costs, is now expected to range from $440 million to $490 million, and, based on these charges, diluted loss per share is expected to range from $0.30 to $0.50.
