Scottsdale, Ariz. — January 28, 2008 — JDA^® Software Group, Inc. today announced financial results for the fourth quarter and full year ended December 31, 2007. JDA reported record total revenues of $98.5 million and software revenue of $22.4 million for fourth quarter 2007, compared to total revenues of $88.6 million and software revenue of $17.7 million in fourth quarter 2006. The Manugistics acquisition, which closed on July 5, 2006, represented $43.4 million of total revenues during fourth quarter 2007 and included $6.4 million of software revenue.

     JDA reported adjusted non-GAAP earnings for fourth quarter 2007 of $0.35 per share, which excluded amortization of acquired software technology and intangibles, restructuring charges and adjustments to acquisition-related reserves and stock-based compensation, as compared to adjusted non-GAAP earnings per share of $0.20 for fourth quarter 2006, which excluded amortization of acquired software technology and intangibles, restructuring charges and adjustments to acquisition-related reserves, stock-based compensation, adjustments to increase the carrying value of Series B Preferred Stock to its redemption value, one-time charges related to the discontinuance and replacement of the Portfolio Replenishment Optimization (PRO) software application and impairment charges. The Company reported GAAP net income for fourth quarter 2007 of $8.0 million or $0.22 per share, as compared to a GAAP net loss of ($0.06) per share in fourth quarter 2006. JDA reported adjusted EBITDA (earnings before interest, taxes, depreciation and amortization) of $22.9 million for fourth quarter 2007, compared to $15.8 million for fourth quarter 2006.

     “Our strong performance in fourth quarter 2007 provided the perfect finish to a record year for JDA. In fact we saw double-digit revenue growth in FY2007, representing a nearly $100 million increase over 2006, along with a $27 million increase in GAAP earnings,” said JDA CEO Hamish Brewer. “Software sales grew 50% in 2007 over 2006 and in the fourth quarter all three regions delivered both year-over-year and quarter-over-quarter sales growth; business is humming at JDA.”

     “Market demand for our comprehensive product line continues to intensify among existing and new customers across every industry. We just returned from the year’s largest retail trade show, the National Retail Federation’s Big Show, and have tallied a record number of leads to add to our already promising pipeline. We are excited to leverage our success and market momentum into 2008,” added Brewer.

     Hamish Brewer and Kristen L. Magnuson, JDA’s Executive Vice President and CFO, will provide guidance for 2008 during JDA’s scheduled conference call.

This press release contains forward-looking statements that are made in reliance upon the safe harbor provisions 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, such forward-looking statements include, without limitation, the following statements by Mr. Brewer: (i) that market demand for our comprehensive product line continues to intensify among existing and new customers across every industry; (ii) that leads generated from the recent National Retail Federation’s Big Show will provide increased opportunities in our sales pipeline; and, (iii) that we can leverage our success and market momentum into 2008. The occurrence of future events may involve a number of risks and uncertainties, including, but not limited to: (a) the difficulty in identifying and realizing material synergies from our Manugistics acquisition, particularly since the acquisition occurred five quarters ago; (b) the difficulty of predicting demand for our software products and services, including the size and timing of individual contracts and our ability to recognize revenue with respect to contracts signed in a given quarter, particularly with respect to our larger customers; (c) the risk that macroeconomic concerns may cause our customers to delay or refrain from purchasing our products and services; and (d) 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.

• We exclude amortization of intangibles 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.

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

• Adjustments to increase the carrying value of Series B Preferred Stock to its redemption value and record a change in the fair value of a related conversion feature are non-routine transactions, not directly related to our core business of selling software and related services and hardware.

• We exclude charges for the discontinuance and replacement of the PRO application as they are a significant non-recurring expense. The exclusion of these charges promotes period-to-period comparisons and transparency.

• Impairment charges are non-routine expenses that cannot be predicted. . The exclusion of these charges promotes period-to-period comparisons and transparency.

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.
