In early July 2005, i2 sold its San Diego-based subsidiary, Trade Service Corporation (TSC). Revenues from this subsidiary had been accounted for in i2’s total license calculations. By removing the TSC revenue accounted for in previous quarters, an adjusted year-over-year quarterly comparison indicates an 11 percent increase in third quarter total license revenue, and a 31 percent year-to-date increase. The chart below offers year-over-year and year-to-date comparisons of i2’s total license revenue with TSC revenue removed.

Operating Expenses

i2 reported total costs and operating expenses of $54.4 million which includes a $2.2 million gain on the sale of TSC assets. In comparison, total costs and operating expenses in the third quarter of 2004 were $90.2.

“In the third quarter we completed the cost reductions we began on March 30, meeting the goals we set out to achieve. We are now able to invest in the best areas of our business to support profitable growth,” said i2 Chief Executive Officer Michael McGrath.

Net Income

The company reported third quarter net income applicable to common shareholders of $8.6 million, or $.33 per fully diluted share, compared to net income of $17.1 million, or $0.75 per fully diluted share, in the third quarter of 2004.

Operating income for the third quarter was $14.8 million versus $20.8 million in the third quarter of 2004. On a year-to-date basis, operating income was $24.7 million in 2005, 70 percent above the same period in 2004.

The company also provides pro-forma operating income to assist shareholders with analysis of financial and business trends related to the company’s operations. The calculations are not in accordance with, or an alternative for, generally accepted accounting principles (GAAP), and may be different from non-GAAP operating income presented by other companies, but are used as a tool by management to assess i2’s business. Pro-forma operating income for the third quarter was $13.7 million compared to ($3.7) million in the year-ago quarter (see table that follows).

Balance Sheet Items

i2 recently reduced its long-term debt with the purchase on the open market of $50 million of its outstanding 5.25% convertible notes due on December 15, 2006. Of the purchase, $21.5 million was settled and recorded in the third quarter, with an additional $28.5 million settled and recorded in early October. The Company ended the quarter with $272.0 million in total cash (including restricted cash and short-term investments), down from $298.3 million in the prior quarter. At the end of the quarter, the gap between the Company’s long term debt and total cash was approximately $23.2 million.

“The repurchase of this debt is another important step in our plan to strengthen our overall balance sheet,” said i2 Chief Financial Officer Michael Berry. “We are optimistic that the combination of our cash balances, our focus on cash flow, opportunities to monetize the value of our assets, and the variety of capital sources available to us will allow us to address our outstanding debt and further establish a proper liquidity balance for i2’s future.”

Management Commentary

“We have transformed i2 into the profitable company we knew it could be, and now we can turn our attention to strategically growing the company by taking advantage of the opportunities created by the next generation of supply chain management,” said McGrath. “We recently released our first wave of next-generation solutions. These are a new type of solution that can provide opportunities for our customers to extend the management of their supply chains at a lower cost and lower risk.”
