To Our Stockholders:

I am writing in response to the many questions we have received since the June 15 jury verdict in the litigation between Dillard’s, Inc. and i2 Technologies, Inc., which JDA Software, Inc. acquired on January 28, 2010. The purpose of this letter is to provide you with our thoughts on that recently announced verdict and to update you on our response plans.

To review briefly, a Texas jury awarded approximately $246 million to Dillard’s under various theories, the substantial majority of which were characterized as consequential, special or punitive damages. The suit related to a software license agreement and services agreement under which Dillard’s had paid i2 approximately $8 million since 2000.

We find the jury decision inexplicable considering the following:

• Both of the i2 products—Replenishment Planner and Demand Planner—were implemented and were formally accepted by Dillard’s;

• Dillard’s used both products in production for many years, and one of the products is used in Dillard’s business through a vendor today;

• Although it was found that i2 had breached the express warranty relating to the software contract, the jury also found that i2 had complied with the terms of both contracts between the two companies ; and

• Our due diligence into this case, prior to entering an agreement to buy i2, was supported by independent advice from external litigators. Their conclusion regarding the Dillard’s litigation was that there was potential financial exposure to i2, but that it was immaterial and that the chances of i2’s actions being interpreted as fraudulent were not material.

Considering the aforementioned facts, this verdict was very much unexpected. I personally do not believe that this award against i2 is just, and we will make every effort to gain a reversal or material reduction of the verdict. To support that effort, we have retained a leading Texas law firm, Haynes and Boone. This firm’s appellate group has a reputation in Texas that is second to none. Leading our Haynes and Boone team are Nina Cortell, co-chair of Haynes and Boone’s appellate section, and Lynne Liberato, former Chair of the Appellate Section of the State Bar of Texas.

As our legal team moves forward in the Dillard’s case, if we are unable to resolve this dispute at the trial court level, the company will pursue all available remedies in the appeals process. We have the right under Texas law to suspend enforcement of the trial court judgment during the appeals process by posting a $25 million bond. We are prepared to do that, as well as to pursue an appeal that could take several years to complete.

In response to inquiries regarding what the Dillard’s case may suggest about the potential outcome of other pending litigation with i2 customers, I am pleased to report that we have recently finalized settlements in the two remaining i2 customer litigation matters. These two settlements were reached for

immaterial amounts. Outside of the ongoing Dillard’s matter, there is no remaining i2 customer-related litigation.

I know that you have made significant investments in our company and our management team and Board of Directors remain, as always, focused upon doing all that we can to deliver a strong return on your investment. The longstanding success we have achieved at JDA is built on a foundation of constantly seeking to do the right thing. We apply these same principles to companies we acquire. We plan to continue doing just that, and I am confident that the long-term trust we have built with our customers will ensure that our business is not unnecessarily disrupted by this news.

I would also like to respond to concerns that a drawn-out legal process in the Dillard’s case could impact our strategic plan to create the world’s leading supply chain company. Because the ultimate outcome of the Dillard’s litigation may be unknown for some time, we intend to operate with conservative assumptions and ensure that the security of the company remains paramount in any decisions we make. We have always operated JDA in a fiscally conservative manner and that will not change. As you know, we look to maximize the value of each acquisition through the full integration of an acquired company before initiating the next transaction. Because we expect to spend the next year or so completing our integration of i2, another large deal would not have been considered until that point, irrespective of this litigation. As such, we are hopeful that our acquisition strategy will be largely unaffected. We remain confident we will achieve our stated goal of becoming a supply chain leader with $1 billion in revenue.

For the last 25 years we have been dedicated to building a franchise of trust and respect with our customers. The Dillard’s verdict does not change what makes JDA enduring:

• Our market leadership, which is built on delivering customer value through superior solutions;

• Our business model and our competitive position which are both very robust; and, importantly,

• Our financial strength.

We will continue to run this company with the same discipline and dedication to excellence we have demonstrated in the past, because we have achieved great market success doing so. Our unwavering commitment to customer value will sustain us through this unusual situation. As a result, we expect to continue to enhance shareholder value for years to come.

We plan to report on our second quarter operating and financial performance in a conference call on July 27 and will provide additional updates at that time. As always, thank you for your ongoing support of JDA.

Sincerely,

Hamish Brewer
President and Chief Executive Officer
