JDA Software Agrees to Litigation Settlement

Scottsdale, Ariz. - November 30, 2011 - JDA^® Software Group, Inc. (“JDA” or “the Company”) (NASDAQ: JDAS), The Supply Chain Company^®, today announced that it has entered into a settlement agreement with Dillard's, Inc. (NYSE: DDS) which brings to conclusion a litigation matter related to a software license and service agreement between i2 Technologies, Inc. (i2) and Dillard's, Inc. (Dillard's) that originated in 2000. JDA acquired i2 in January of 2010.

Under the terms of the settlement agreement, i2 agreed to pay $57 million to Dillard's for final and full resolution of any and all claims against the Company. In June 2010, the litigation matter was adjudicated in Dillard's favor and a judgment entered in the amount of $237 million. i2 appealed that judgment and the matter had been pending in the court of appeals. JDA posted a bond in 2010, backed by $25 million, which will be released back to the Company. That cash, as well as approximately $3 million in expected insurance proceeds and cash on hand, will be used to pay the settlement. JDA had more than $320 million of cash on hand as of September 30, 2011. The Company expects to take a pre-tax charge of $35 million in the fourth quarter 2011, which represents the settlement amount, net of insurance recoveries, less amounts previously accrued in the financial statements.

“While we remain confident in the strength of our legal position, we entered into the settlement agreement to bring this matter to a conclusion,” said JDA Software President and Chief Executive Officer Hamish Brewer. “With this settlement, and the $37.5 million favorable patent infringement settlement earlier this year, we have now concluded all known, material outstanding litigation related to i2. We are focused on completing a very successful year and continuing to execute on our strategy of enhancing long-term customer and shareholder value.”
