November 21, 2012 - An investor in units of Hi-Crush Partners LP (NYSE: HCLP) filed a lawsuit in the U.S. District Court of the Southern District of New York against Hi-Crush Partners LP over alleged securities laws violations in connection with certain allegedly false and misleading statements in the initial public offering.

According to the complaint the plaintiff alleges on behalf of all persons or entities who purchased the common stock of Hi-Crush Partners LP (NYSE: HCLP) in and/or following Hi-Crush Partners LP’s initial public offering completed on or about August 16, 2012, that Hi-Crush Partners LP and others violated the Securities Act of 1933.

On August 16, 2012, Hi-Crush Partners LP raised proceeds of approximately $220 million in its initial public offering (“IPO”), selling approximately 12.9 million common units at $17 per unit.

Units of Hi-Crush Partners LP (NYSE: HCLP) reached on September 24, 2012, $22.74 per unit.

However, the plaintiff alleges that the Registration Statement issued in connection with Hi-Crush Partners LP's initial public offering completed on or about August 16, 2012 was allegedly negligently prepared and, as a result, contained allegedly 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. Specifically, so the plaintiff, the Registration Statement allegedly highlighted that Baker Hughes Incorporated as one of Hi-Crush Partners LP’s two largest customers and emphasized that it was obligated to purchase sand from Hi-Crush Partners LP pursuant to a May 2012 “take-or-pay contract” that “require[d]” Baker Hughes Incorporated “to pay a specified price for a specified volume of frac sand each month.”

Then on November 13, 2012, before the market opened, Hi-Crush Partners LP reported its third quarter 2012 results. Among other things, Hi-Crush Partners LP also disclosed the termination of the supply agreement with Baker Hughes Oilfield Operations, Inc. Hi-Crush Partners LP said that on September 19, 2012, Baker Hughes provided notice that it was terminating the contract. Hi-Crush Partners LP said it believes that Baker Hughes’ termination was wrongful and a direct effort to circumvent its binding purchase obligations under the supply agreement.

Units of Hi-Crush Partners LP (NYSE: HCLP) dropped from $20.79 per unit on November 9, 2012 to as low as $13.44 per unit on November 13, 2012.

On November 21, 2012 Hi-Crush Partners LP (NYSE: HCLP) units closed at $16.01.
