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.
