The Complaint alleges that throughout the Class Period, the Company made false and/or misleading statements and failed to disclose material adverse facts about the Company's business, operations, and prospects. On October 21, 2014, the Company announced that it would restate second quarter 2014 results after identifying approximately $22 to $24 million in losses caused by the deterioration of a “significant pipeline construction project.” The Company further stated that, “this deterioration consists of the reversal of approximately $8.0 million in pre-tax income previously recognized and the recognition of approximately $14.0 to $16.0 million in estimated pre-tax losses at project completion.” The Company also stated that its Audit Committee is evaluating the sufficiency of the Company’s internal controls. As a result of this news, Willbros stock dropped $2.56 per share, or over 33%, to close at $5.09 per share on August 13, 2014, on heavy volume.”
