Scottsdale, Ariz. — January 26, 2008 — JDA ^® Software Group, Inc. (NASDAQ: JDAS) today announced financial results for the fourth quarter and year ended December 31, 2008. JDA reported total revenues of $106.2 million and software revenues of $34.3 million for fourth quarter 2008, compared to total revenues of $98.5 million and software revenues of $22.4 million for fourth quarter 2007. For the twelve months ended December 31, 2008, JDA reported total revenues of $390.3 million and software revenues of $92.9 million, compared to total revenues of $373.6 million and software revenues of $73.6 million for the twelve months ended December 31, 2007.

Fourth Quarter 2008 Financial Summary

• Adjusted EBITDA (Earnings before interest, taxes, depreciation and amortization) was $28.0 million in fourth quarter 2008, compared to $22.9 million in fourth quarter 2007, a 22% increase year-over- year.

• Adjusted non-GAAP earnings for fourth quarter 2008 were $0.43 per share as compared to $0.35 in fourth quarter 2007, and exclude amortization of acquired software technology and intangibles, restructuring charges, stock-based compensation and the costs of the terminated i2 acquisition.

• The Company reported a GAAP net loss for fourth quarter 2008 of $10.4 million or $.34 per share, compared to GAAP net income of $8 million or $0.22 per share in fourth quarter 2007. The GAAP net loss for fourth quarter 2008 includes $25.1 million in operating expenses and $4.6 million of finance costs related to the terminated acquisition of i2 Technologies.

• DSOs were 67 days at the end of fourth quarter 2008, compared to 58 days at the end of third quarter 2008 and 68 days at the end of fourth quarter 2007. DSOs increased sequentially in fourth quarter 2008 compared to third quarter 2008 due to the higher volume of software revenues which have longer payment terms than maintenance or service billings.

• The Company reported negative cash flow from operations of $23.6 million in fourth quarter 2008 compared to positive cash flow from operation of $18.8 million in third quarter 2008 and $16.0 million in fourth quarter 2007.

“Safe Harbor” Statement under the U.S. Private Securities Litigation Reform Act of 1995

           We do not believe this press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are generally accompanied by words such as “will,” and “expect” and other words with forward-looking connotations. In this press release we have included statements with forward-looking implications, including (i) Mr. Brewer’s statement that “our solutions offer what the market and our customers need right now . . . .” The occurrence of future events may involve a number of risks and uncertainties, including, but not limited to: (a) the possibility that, despite our strong software sales in 2008, demand for our solutions may weaken, particularly given the current worldwide negative financial and economic environment; and (b) other risks detailed from time to time in the “Risk Factors” section of our filings with the Securities and Exchange Commission. Additional information relating to the uncertainty affecting our business is contained in our filings with the SEC. As a result of these and other risks, actual results may differ materially from those predicted. JDA is not under any obligation to (and expressly disclaims any such obligation to) update or alter its forward-looking statements, whether as a result of new information, future events or otherwise.

Use of Non-GAAP Financial Information

          This press release and the related conference call contain non-GAAP financial measures. In evaluating the Company’s performance, management uses certain non-GAAP financial measures to supplement consolidated financial statements prepared under GAAP. Management’s presentation of non-GAAP financial measures is intended to be supplemental in nature and should not be considered in isolation or as a substitute for the most directly comparable GAAP measures.

Use and Economic Substance of Non-GAAP Financial Measures Used by JDA

          The Company uses non-GAAP measures of performance, including adjusted operating income, EBITDA (earnings before interest, taxes, depreciation and amortization) and earnings per share, in its public statements. Management uses, and chooses to disclose, these non-GAAP financial measures because (i) such measures provide an additional analytical tool to clarify the Company’s results from operations and help the Company to identify underlying trends in its results of operations; (ii) the Company uses non-GAAP earnings measures, including EBITDA, as a measure of profitability because such measures help the Company compare its performance on a consistent basis across time periods; and (iii) these non-GAAP measures are employed by the Company’s management in its own evaluation of performance and are utilized in financial and operational decision making processes, such as budget planning and forecasting. The Company also internally uses adjusted EBITDA measures for determining (a) compliance with certain financial covenants in its credit agreement and (b) executive and employee compensation. Set forth below are additional reasons why specific items are excluded from the Company’s non-GAAP financial measures:

• Amortization charges for acquired technology are excluded because they result from prior acquisitions, rather than ongoing operations, and absent additional acquisitions, are expected to decline over time.

• Amortization charges for other intangibles are excluded because they are non-cash expenses, and while tangible and intangible assets support our business, we do not believe the related amortization costs are directly attributable to the operating performance of our business.

• Restructuring charges and adjustments to acquisition-related reserves are significant non-routine expenses that cannot be predicted and typically relate to a change in our business model or to a change in our estimate of the costs to complete a plan to exist an activity of an acquired company. The exclusion of these charges promotes period-to-period comparisons and transparency. Such charges are primarily related to severance costs and/or the disposition of excess facilities driven by the changes to our business model.

• Stock-based compensation is not an expense that typically requires or will require cash settlement by the Company.

• The costs associated with the terminated acquisition of i2 Technologies, which include a $20 million reverse termination fee and other finance and related costs, are significant non-routine expenses. Exclusion of these costs promotes period-to-period comparisons and transparency as we do not believe these costs are directly attributable to the operating performance of our business.

• Sales of office facilities are non-routine transactions, not directly related to our core business of selling software and related services and hardware.

Material Limitations (and Compensation thereof) Associated with the Use of Non-GAAP Financial Measures

          Non-GAAP financial measures have limitations as an analytical tool and should not be considered in isolation or as a substitute for the Company’s GAAP results. In the future, the Company expects to continue reporting non-GAAP financial measures excluding items described above and the Company expects to continue to incur expenses similar to the non-GAAP adjustments described above. Accordingly, exclusion of these and other similar items in our non-GAAP presentation should not be construed as an inference that these costs are unusual, infrequent or non-recurring.

          Some of the limitations in relying on non-GAAP financial measures are:

• Amortization of acquired technology and intangibles, though not directly affecting our current cash position, represent the loss in value as the technology in our industry evolves, is advanced or is replaced over time. The expense associated with this loss in value is not included in the non-GAAP net income presentation and therefore does not reflect the full economic effect of the ongoing cost of maintaining our current technological position in our competitive industry which is addressed through our research and development program.

• The Company may engage in acquisition transactions in the future. In addition, we incur other restructuring charges from time to time when necessary to adjust our business model. Restructuring related charges may therefore continue to be incurred and should not be viewed as non-recurring.

• Stock-based compensation is an important component of our incentive compensation arrangements and will be reflected as expenses in our GAAP results for the foreseeable future under SFAS 123R.

• Other companies, including other companies in our industry, may calculate non-GAAP financial measures differently than we do, limiting their usefulness as a comparative measure.

          We compensate for these limitations by relying primarily on our GAAP results and using non-GAAP financial measures only supplementally. We also provide reconciliations of each non-GAAP financial measure to our most directly comparable GAAP measure, and we encourage investors to review carefully those reconciliations.

Usefulness of Non-GAAP Financial Measures to Investors

          The Company believes that the presentation of these non-GAAP financial measures is warranted for several reasons. First, such non-GAAP financial measures provide investors and management an additional analytical tool for understanding the Company’s financial performance by excluding the impact of items which may obscure trends in the core operating performance of the business. Second, since the Company has historically reported non-GAAP results to the investment community, the Company believes the inclusion of non-GAAP numbers provides consistency and enhances investors’ ability to compare the Company’s performance across financial reporting periods.
