JDA Reports Significant Earnings and Software License Growth in Third Quarter
Software Revenues Up 70% Over Prior Year and 14% Sequentially

     Scottsdale, Ariz. – October 24, 2005 – JDA® Software Group, Inc. (Nasdaq: JDAS) today announced final financial results for the quarter ended September 30, 2005. JDA reported total revenues of $55.6 million and software revenues of $17.4 million, compared to total revenues of $50.3 million and software revenues of $10.2 million in third quarter of 2004.

     JDA reported GAAP net income for the third quarter 2005 of $3.7 million, or $0.13 per share, as compared to GAAP net income of $1.6 million, or $0.06 per share in third quarter 2004. JDA reported adjusted non-GAAP earnings for third quarter 2005 of $0.17 per share, versus adjusted non-GAAP earnings per share of $0.04 for third quarter 2004. The non-GAAP earnings results exclude amortization of acquired software technology and intangibles, stock-based compensation expense on restricted stock units, a net gain on acquisition break-up fee, a gain on sale of securities, and certain non-recurring tax benefits and refunds, all of which are itemized in the attached schedule of non-GAAP measures of performance.

     “The third quarter delivered an excellent software result for what is traditionally the weakest quarter of the year with a 70% increase in software licenses over the prior year quarter,” said Hamish Brewer, JDA Chief Executive Officer. “We closed 76 deals in a highly competitive environment, including 12 multi-product transactions and three large software contracts with combined software revenues surpassing $10 million, not all of which was recognized in third quarter 2005.”

     “JDA’s distinct competitive advantage is becoming very clear in an industry of consolidating software vendors. Our value proposition of delivering high value add solutions through a low cost delivery model is clearly understood and being well received by both retailers and suppliers. I feel very positive about our competitive positioning,” said Brewer.
