The complaint charges Carbo Ceramics and certain of its officers and directors with violations of the Exchange Act. The Company manufactures and supplies ceramic proppants primarily used in the hydraulic fracturing of natural gas and oil wells in the United States and internationally.

The complaint alleges that, throughout the Class Period, defendants issued materially false and misleading statement regarding the Company’s business and prospects. Specifically, defendants misrepresented and/or failed to disclose the following adverse facts: (a) that the Company was experiencing a dramatic decline in proppant sales in the Haynesville region; (b) that the Company was being negatively impacted by logistical problems such that it was not able to shift resources to liquid plays where drilling activity was increasing; and (c) that, based on the foregoing, defendants lacked a reasonable basis for their positive statements about the Company, its operations and earnings during the Class Period.
