November 15, 2012, Atlanta, GA – RedPrairie today announced that its affiliate, RP Crown Acquisition Sub LLC, has commenced a cash tender offer to purchase all outstanding common shares of JDA Software Group, Inc. (NASDAQ: JDAS). As previously announced on November 1, 2012, entities affiliated with RedPrairie and JDA entered into a definitive merger agreement under which an affiliate of RedPrairie would acquire all outstanding shares of JDA common stock for $45.00 per share, in a transaction valued at approximately $1.9 billion.

Following the successful closing of the tender offer, shareholders of JDA will receive $45.00 in cash for each common share of JDA validly tendered and not properly withdrawn in the offer, without interest and less any required withholding taxes.

Affiliates of RedPrairie are filing with the Securities and Exchange Commission (SEC) today a tender offer statement on Schedule TO, including an Offer to Purchase and related Letter of Transmittal, setting forth in detail the terms of the tender offer. Additionally, JDA is filing with the SEC today a solicitation/recommendation statement on Schedule 14D-9 setting forth in detail, among other things, the recommendation of the JDA Board of Directors by unanimous vote that JDA’s shareholders accept the tender offer and tender their shares.

The tender offer is scheduled to expire at 11:59 p.m., New York time, on December 13, 2012, unless extended in accordance with the merger agreement and applicable rules and regulations of the SEC. The tender offer and merger are subject to customary closing conditions, including the satisfaction of the minimum tender condition in the tender offer that at least 79% of JDA’s outstanding shares on a fully diluted basis be tendered, and clearance from antitrust regulatory authorities.
