License deals were spread across all regions and all major industry sectors, with high tech and consumer goods and retail (CG&R) continuing to be leading industries for i2.

Preliminary estimated total costs and operating expenses for the second quarter are expected to be between $117 million and $122 million, including approximately $9 million of audit and legal fees related to the company’s re-audits and investigations.

As previously disclosed, i2 ended the first quarter with $441 million in cash and investments. This cash balance was unaffected by the restatement of results from prior years. Subsequently, in the second quarter, the Company prepaid its $60.9 million senior convertible note for $59.2 million, representing a 5.5 percent discount to principal and interest accrued. This note was due in September 2003. In addition, i2 settled a lease obligation for a facility no longer in use for $7.6 million in cash and a non-negotiable promissory note of $6.8 million. The Company ended the second quarter with approximately $355 million in cash and investments.

The company intends to file its Form 10-Q for the first quarter in August 2003.

First Half 2003 Recap

i2 achieved over 85 go-lives over the past two quarters. The company sold into the consumer goods and retail, automotive and industrial, high technology and process industries. However, the Company experienced challenging conditions, in part resulting from the re-audits.

“Customers have continued to show support for i2 and interest in our next generation closed-loop supply chain management solutions and services in the past two quarters,” said Sanjiv Sidhu, i2 Chairman and CEO. “For 15 years, we have been providing leading supply chain management solutions to businesses around the world. With the re-audits behind us, we look forward to building on that heritage and helping customers solve their most difficult business problems.”
