Rentech Announces Final Court Approval of Settlement of Shareholder Derivative Lawsuits

Rentech, Inc. (NYSE AMEX: RTK) announced today that it has received final court approval for the settlements of the shareholder derivative lawsuits against the Company and a number of its current and former directors and officers. The lawsuits related to the Company’s restatement in December 2009 of certain of its financial statements for fiscal year 2008 and the first three quarters of fiscal year 2009. The Company believes that it is in the best interests of its stockholders to settle the matters at a reasonable cost to avoid potentially protracted and expensive litigation. The Company and the individual defendants have denied any liability or wrongdoing in connection with the allegations contained in these lawsuits.

The approval of settlements for the consolidated shareholder derivative lawsuits in United States District Court for the Central District of California (In re Rentech Derivative Litigation, Lead Case No. 2:10-cv-0485-GHK-PJW) and the Superior Court of the State of California for the County of Los Angeles (Andrew L. Tarr v. Dennis L. Yakobson, et al., LASC Master File No. BC430553) provide that the Company will adopt certain governance practices, and pay (or cause its insurance carrier to pay) plaintiffs’ attorneys’ fees and expenses of $300,000. The Company expects that over half of the aggregate shareholder derivative settlement payments will be covered by its insurance carriers.
