JDA Software Announces Record First Quarter 2010 Results
Integration of i2 Technologies is on Track

Scottsdale, Ariz. — April 27, 2010 — JDA^® Software Group, Inc. (NASDAQ: JDAS), The Supply Chain Company^®, today announced financial results for the first quarter ended March 31, 2010. JDA reported record total revenues of $131.6 million, a 58 percent increase from $83.3 million of revenue reported in first quarter 2009. Software license and subscription revenues increased 87 percent in the first quarter 2010 to $28.7 million from $15.3 million in first quarter 2009, and adjusted EBITDA increased 88 percent to $31.4 million in first quarter 2010 from $16.7 million in first quarter 2009.

          JDA also reported adjusted non-GAAP earnings for first quarter 2010 of $0.38 per share, an increase of 46 percent from $0.26 per share in first quarter 2009. The GAAP loss applicable to common shareholders for first quarter 2010 was $4.3 million or ($0.11) per share, and includes acquisition-related costs, compared to GAAP net income of $2.6 million or $0.08 per share in first quarter 2009. Results for 2010 include the completion of the acquisition of i2 Technologies, Inc. (“i2”) as of January 28, 2010.

          “I am pleased to report that we delivered solid results in a quarter that featured our largest acquisition to date,” said JDA president and chief executive officer Hamish Brewer. “In the 90 days since completing the i2 acquisition we have fully integrated teams across all regions and functional areas of the company and completed a new JDA product roadmap that demonstrates the breadth, depth and future direction of our powerful suite of planning, optimization and execution solutions.”

First Quarter 2010 Financial Summary

•

Adjusted non-GAAP earnings per share for first quarter 2010 were $0.38 using 40.0 million fully diluted shares compared to $0.26 per share in first quarter 2009, using 35.1 million fully diluted shares. Adjusted non-GAAP earnings exclude amortization of acquired software technology and intangibles, restructuring charges, stock-based compensation, and costs related to the acquisition and transition of i2.

•

The GAAP net loss applicable to common shareholders for first quarter 2010 was $4.3 million or ($0.11) per share, compared to net income of $2.6 million or $0.08 per share in first quarter 2009.

•

DSO increased to 74 days at the end of first quarter 2010 from 71 days at the end of first quarter 2009, primarily due to the receivables acquired from i2. JDA is applying its focused collection process to the new receivables as a part of the overall company integration process, with the goal of reducing the overall DSO.

•

Cash flow from operations was $12.2 million in first quarter 2010, compared to cash flow from operations of $33.1 million in first quarter 2009. The change in operating cash flow in the current period was primarily driven by lower cash provided by working capital as compared to first quarter 2009. This is primarily due to the increase in the receivables from higher revenue in the current year, the payment of approximately $6.7 million of acquisition related costs in first quarter of 2010, as well as the collection of a significant receivable in the first quarter of 2009.

•

Cash and cash equivalents, including restricted cash, were $167.5 million at March 31, 2010, compared to $363.8 million at December 31, 2009, which included net proceeds from the issuance of $275.0 million of Senior Notes that were used to complete the acquisition of i2 on January 28, 2010.

First Quarter 2010 Highlights

          “Our strong sales performance this quarter demonstrates a vote of customer confidence in our strategy to build a world-class supply chain company through both organic and acquisition growth,” commented Brewer. “We saw little to no deal erosion as a result of the i2 acquisition, and in fact believe that companies now, more than ever, understand the value of solutions from a company that specializes in supply chain. As a result, JDA continues to be the technology provider of choice for companies around the world.”

          The following presents a high-level summary of JDA’s regional sales performance:

	•		JDA reported $18.9 million in software license and subscription revenues in its Americas region during first quarter 2010, compared to $19.1 million in fourth quarter 2009 and $11.1 million in first quarter 2009.

“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. Nevertheless, if remarks in this press release are considered to be ``forward-looking’’ or to have forward-looking implications, such as Mr. Brewer’s comments regarding our accomplishments to date in integrating i2 and that JDA continues to be the technology provider of choice for companies around the world, we would remind our investors and prospective investors that future events may involve risks and uncertainties. Risks and uncertainties that may affect our business are detailed from time to time in the ``Risk Factors’’ section and other sections of our filings with the Securities and Exchange Commission. As a result of these and other risks, actual results may differ materially from those predicted. We undertake no obligation to update information in this release, except as required by law.

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 net 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 software 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 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 exit 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.
	•		Acquisition-related costs associated with the acquisition of i2 and the non-recurring transition costs to integrate the acquisition 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.

          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

•

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.

•

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.
