("Carbo Ceramics") (NYSE: CRR) common stock during the period between October 27, 2011 and January 26, 2012, inclusive (the "Class Period")

What are the allegations in the complaint? The complaint alleges that, throughout the Class Period, defendants issued materially false and misleading statements 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 defendants lacked a reasonable basis for their positive statements about the company, its operations and earnings during the Class Period. Based upon the foregoing, the complaint charges the company and certain of its officers with violations of the Securities Exchange Act of 1934.
