JDA Software Announces Preliminary First Quarter 2007 Results
In Preparation for Analyst Meeting at FOCUS 2007

Scottsdale, Ariz. — April 16, 2007 — JDA^® Software Group, Inc. today announced preliminary financial results for the first quarter ended March 31, 2007 in order to provide early visibility into first quarter 2007 results for the Analyst Meeting scheduled to take place on Tuesday, April 17^th in New Orleans at JDA’s annual FOCUS user conference. Based on unaudited results, JDA anticipates total revenues of approximately $89.7 million to $90.7 million and software revenues of $17.0 million for first quarter 2007, including $36.5 million and $4.2 million from Manugistics, respectively, compared to total revenues of $47.9 million and software revenues of $7.1 million for first quarter 2006.

JDA expects GAAP net income for first quarter 2007 to be $0.15 to $0.17 per share, as compared to a GAAP net income of $487,000, or $0.02 per share in first quarter 2006. The Company expects to report adjusted non-GAAP earnings for first quarter 2007 of approximately $0.26 to $0.28 per share, which excludes amortization of acquired software technology and intangibles, restructuring charges, stock-based compensation and a gain on the sale of an office facility, as compared to adjusted non-GAAP earnings of $0.06 per share for first quarter 2006, which excluded amortization of acquired software technology and intangibles. In addition the company expects to report adjusted EBITDA (Earnings before interest, taxes, depreciation and amortization) of $18.5 million to $19.6 million for the first quarter of 2007 compared to $4.0 million for first quarter 2006. For purposes of the attached schedule of non-GAAP measures of performance, the Company has included the mid-point of our estimated range of GAAP net income for first quarter 2007.

JDA ended first quarter 2007 with $61.1 million in cash and cash equivalents after paying off $15 million of debt, leaving a debt position of $126.1 million.

“2007 is an important year for JDA as we consolidate and leverage the operations of Manugistics and begin to see the results of the organizational changes we put in place in 2006,” commented Hamish Brewer, CEO of JDA Software. “Combining the positive impact of Manugistics with strong year-over-year growth in sales of the heritage JDA products, this first quarter result gives us a flying start to the year.”

These anticipated results are preliminary and based on partial information and management assumptions. JDA plans to announce final results during its regularly scheduled conference call for first quarter 2007 on April 23, 2007.
