The Rosen Law Firm, P.A. announces a class action has been filed against Lone Pine Resources, Inc. (NASDAQ: LPR) alleging that Lone Pine made false statements of material facts in its prospectus issued in connection with the Company’s May 26, 2011 initial public offering. Namely, that Lone Pine failed to disclose in its IPO documents that the Company was facing significantly increased costs and disruption in production volumes attributed to a major oil sales pipeline rupture in late April 2011 and a large forest fire in the same area in Mid-May. When the market learned of this adverse information, the price of Lone Pine dropped damaging investors.
