Hi-Crush is a publicly traded Delaware limited partnership that produces monocrystalline “frac” sand, a specialized mineral that is used as a proppant to enhance the recovery rates of hydrocarbons from oil and natural gas wells. The complaint alleges that the Registration Statement issued in connection with the Company’s August 16, 2012 IPO was negligently prepared and, as a result, contained untrue statements of material facts, omitted to state other facts necessary to make the statements made not misleading and was not prepared in accordance with the rules and regulations governing its preparation.
