The Rosen Law Firm, P.A., a global investor rights law firm, announces it is investigating potential securities claims on behalf of shareholders of Willbros Group Inc. (NYSE:WG) resulting from allegations that Willbros Group may have issued materially misleading business information to the investing public.

On March 17, 2015, Willbros Group announced that it is unable to timely file its Form 10-K for the year ended December 31, 2014. In its announcement, the Company stated that it “does not expect to be in compliance with its Maximum Leverage Ratio and Minimum Interest Coverage Ratio for the period from March 31, 2015 through March 31, 2016.” The Company further stated “that a material weakness existed at December 31, 2014, over the assessment of significant risks and uncertainties associated with its ability to comply with financial covenants contained in its credit agreements, and over the assessment of its ability to meet its liquidity and capital resource needs for a reasonable period of time, primarily as a result of not reflecting certain business conditions timely and adequately in its forecast process.” On this news, shares of Willbros Group fell $2.79 per share or over 50% from its previous closing price to close at $2.69 per share on March 18, 2015.
