Levi & Korsinsky announces that a class action lawsuit has been commenced in the United States District Court for the Central District of California on behalf of investors who purchased Tetra Tech, Inc. (“Tetra Tech” or the “Company”) (Nasdaq: TTEK) stock between May 3, 2012 and June 18, 2013. For more information, click here: http://zlk.9nl.com/tetra-tech-ttek/. The complaint alleges that the Company misrepresented and/or failed to disclose: (a) that claims by customers and cost overruns created an acute risk that the Company would need to take an earnings charge; (b) that decreased demand for the Company’s services would lead to project closures; and (c) the extent to which Tetra Tech’s revenues would be impacted by an overall decline in the Eastern Canadian mining and oil industry. If you suffered a loss in Tetra Tech you have until August 27, 2013 to request that the Court appoint you as lead plaintiff. Your ability to share in any recovery doesn’t require that you serve as a lead plaintiff. To obtain additional information, contact Joseph E.
