The Shuman Law Firm announces that it is investigating potential claims against certain officers and directors of Hi-Crush Partners LP (“Hi-Crush” or the “Company”) (NYSE: HCLP). Hi-Crush is a Texas-based company that operates as a producer of monocrystalline sand used in natural gas and oil wells. The Firm’s investigation concerns the Company’s announcement that the Securities Exchange Commission had requested information concerning a contract dispute with Baker Hughes Oilfield Operations, Inc. (“Baker Hughes”). On September 19, 2012, Baker Hughes provided notice to Hi-Crush that it was terminating its long-term, take-or-pay supply contract with Hi-Crush. The Baker Hughes contract accounted for approximately one-fifth of Hi-Crush’s revenue projections. Hi-Crush and Baker Hughes continue to engage in litigation over the terminated contract. When the Company publicly announced the details of the Baker Hughes dispute on November 13, 2012, Hi-Crush’s stock price fell approximately 22%.
