Net revenues for the fourth quarter of 2003 increased 28% on a year-over-year basis to $23.0 million compared to $18.0 million for the fourth quarter of 2002. Net income on a GAAP basis for the fourth quarter of 2003 was $2.3 million, or $0.04 per diluted share, compared to $225,000, or less than one cent per diluted share, for the fourth quarter of 2002. Ixia's fourth quarter GAAP results included non-cash charges of $1.3 million related to acquisition related intangible assets and $374,000 for stock-based compensation and a tax benefit of $150,000 associated with stock-based compensation. Excluding the effects of these items, non-GAAP net income was $3.8 million, or $0.06 per diluted share, compared to $2.8 million, or $0.05 per diluted share, for the same period last year after excluding the effects of similar items. 4 "Revenues increased 7% over a very strong third quarter, driven by increasing software sales and penetration of new markets," commented Errol Ginsberg, President and Chief Executive Officer of Ixia. "Internationally, we saw good strength in Europe and Canada, while sales to Asia Pacific were lower compared to the third quarter's record levels but still showed strong year-over-year growth. Revenue from enterprise customers doubled sequentially, and we were pleased with our success in penetrating our first enterprise vertical -- financial services -- with key sales to Merrill Lynch, Morgan Stanley, Wells Fargo and leading U.S. stock exchanges. Momentum in this strategic financial services vertical is being driven by strong demand for both our Ethernet hardware products and our innovative software products such as Chariot." "Overall, software sales accounted for 16% of total revenue, increasing sequentially by 31%," added Mr. Ginsberg. "The success of our software product offerings was also reflected in a record 114 new customers for the quarter including such leaders as Booz Allen Hamilton, Coca-Cola, Naval Research Labs, and Rogers Cable. Late in the quarter, we launched IxChariot, which offers full integration of the Chariot product line into our Real World Traffic suite. We expect IxChariot to become an increasing percentage of our Chariot sales and to improve gross profit margins on the product line." As of December 31, 2003, Ixia had approximately $121.9 million in cash and investments with no debt. Ixia will host a conference call today for analysts and investors to discuss its quarterly results at 5:00 p.m. ET.
