Former Attorney General of Louisiana Charles C. Foti, Jr., Esq. and the law firm of Kahn Swick & Foti, LLC (“KSF”) are investigating the proposed merger of Whiting Petroleum Corporation (NYSE: WLL) with Oasis Petroleum Inc. (NasdaqGS: OAS). Under the terms of the proposed transaction, shareholders of Whiting will receive only $6.25 in cash and 0.5774 shares of Oasis for each share of Whiting that they own. KSF is seeking to determine whether the merger and the process that led to it are adequate, or whether the merger undervalues the Company.

If you believe that this transaction undervalues the Company and/or if you would like to discuss your legal rights regarding the proposed sale, you may, without obligation or cost to you, e-mail or call KSF Managing Partner Lewis S. Kahn (lewis.kahn@ksfcounsel.com) toll free at any time at 855-768-1857, or visit https://www.ksfcounsel.com/cases/nyse-wll/ to learn more.
