DALLAS – July 31, 2007 – i2 Technologies, Inc. (NASDAQ: ITWO) today announced the resignation of Michael E. McGrath as president and chief executive officer (CEO), effective July 30, 2007. The company had previously announced in May that McGrath was expected to retire from i2 by the end of the year.

“Michael became CEO during a critical time in our history, and brought a great deal of energy and passion to the position while leading us through many key initiatives, including stabilizing the company financially, improving our management foundation and setting the stage for future growth,” said i2 Founder and Chairman Sanjiv Sidhu. “Under his leadership, i2 has achieved eight consecutive quarters of profitability and improved liquidity. His increased focus on our services business has led to increases in our services revenue as we continue to transition to a solutions-oriented provider. His vision in the area of new-generation supply chain management solutions has helped i2 continue its leadership in the supply chain management space. Michael’s contributions have been many and we are grateful for all he has done on behalf of i2.”

“I have appreciated the opportunity to serve i2 as its president and CEO the last two and a half years,” said McGrath. “I will miss the daily contact that I have had working with i2’s world-class employees and customers. i2 has a bright future and I know the company will continue to deliver tremendous value to the companies it serves.”

McGrath, who intends to pursue other opportunities, continues as a director of the company and is expected to remain employed by i2 in an advisory capacity as CEO emeritus through October 31, 2007. In that role, he will continue to assist the board of directors with the search for a new CEO.
