JDA Completes Final Milestone in Manugistics Acquisition with Delivery of Common Architecture Platform.

Preliminary Results for Fourth Quarter Show Sequential Software Increase Due to Solid Demand for the Combined JDA/Manugistics Offering

SCOTTSDALE, Ariz. -- JDA[R] Software Group, Inc., the leading provider of end-to-end demand and supply chain optimization solutions, today announced the completion of its final integration initiatives related to the Company's July 2006 acquisition of Manugistics. To maximize the synergies of the acquisition, JDA has adopted Manugistics' open and scalable architecture platform -- successfully deployed by more than 100 large-scale customers -- as the underlying foundation for its market-leading suite of advanced planning and optimization solutions. JDA expects to realize additional annualized cost savings in excess of $15 million from adopting this platform, branded the JDA Enterprise Architecture[TM].

Providing a highly scalable platform and rich user experience, the JDA Enterprise Architecture creates a true market breakthrough. By making possible one view of demand across all enterprise planning and optimization activities, customers will make faster, smarter decisions in manufacturing, sourcing, supply chain planning, distribution, merchandising, logistics, promotions, replenishment and shelf optimization. Fueling this heightened decision-making will be a single common advantage: advanced and detailed insight into consumer behavior throughout the enterprise. Already able to deliver 20 solutions on the JDA Enterprise Architecture, the Company will demonstrate its time-to-market advantage by delivering its first new application on this platform as early as the second quarter of this year.

"We have spent the past six months analyzing the Manugistics platform and the outcome has surpassed our expectations," said Hamish Brewer, JDA CEO. "We are convinced that this architecture provides by far the most scalable and proven architecture for advanced planning and optimization solutions. Additionally, this decision has dramatically accelerated our time to market for a fully integrated suite, which is deliverable today on a platform that is proven in over 100 major customers.

"The sales growth in the Americas and EMEA has already underscored the revenue opportunities created by the combination of JDA and Manugistics. Although we experienced a number of earnings setbacks in the quarter, many of which were related to the integration of Manugistics, I do not anticipate ongoing recurrence of these detrimental impacts," added Brewer.

Preliminary Fourth Quarter Results

JDA today also released preliminary, unaudited results for the fourth quarter of 2006. JDA anticipates total revenues of approximately $89 million and software revenues of approximately $17.7 million for fourth quarter 2006, compared to total revenues of $89.2 million and software revenues of $13.7 million for third quarter 2006. For fourth quarter 2005 JDA reported total revenues of $55.1 million and software revenues of $15.6 million. JDA projects adjusted EBITDA of approximately $14 million for fourth quarter 2006.

According to JDA EVP/CFO Kristen L. Magnuson, preliminary software sales within JDA's Americas and Europe, Middle East and Africa (EMEA) regions either met or exceeded expectations. "We are pleased with our sequential and quarter-over-quarter increase in software sales and with our future prospects based on the strong demand in our pipeline for the combined JDA/Manugistics product suite.

"The EBITDA variance from our prior forecast was primarily related to lower than expected software licenses in Asia Pacific and a larger than expected sequential decline in consulting services revenues. Additionally we accrued $1.8 million of one-time expenses related to our de-listing of the Portfolio Replenishment Optimization (PRO) software, which has been replaced with the Manugistics Demand and Fulfillment solution," said Magnuson.

The preliminary, unaudited results are based on partial information and management assumptions. JDA plans to announce final results for the fourth quarter and year ended December 31, 2006 during its regularly scheduled conference call on January 29, 2007.

Acquisition Synergies Result in Workforce Reduction

With the synergies achieved by adopting the JDA Enterprise Architecture, JDA will reduce approximately 100 associates within its new product development team. This reduction, effective immediately, is expected to result in incremental cost synergies of more than $15 million in 2007. Affected employees, located predominantly at its Scottsdale, Arizona headquarters, will be offered severance packages, outplacement services, counseling and other assistance and support. With this reduction, JDA will employ approximately 1,600 associates worldwide, including approximately 440 in new product development.

"The decision to reduce our workforce was a very difficult one to make. We have long viewed our global associates as our greatest competitive advantage," said Brewer. "However, the advantages of standardizing on one platform made this decision compelling. We will now be able to reduce our research and development spending so that it is more in line with industry norms. It will also bring simplification to our product development activities and enable our developers to re-focus their efforts on the delivery of new enhancements and functions for JDA's next generation and market-ready solutions," added Brewer.
