Net revenues for the third quarter of 2003 increased 28.3% on a year-over-year basis to $21.6 million compared to $16.9 million for the third quarter of 2002. Net income on a GAAP basis for the third quarter of 2003 was $2.4 million or $0.04 per diluted share, compared to $1.2 million, or $0.02 per diluted share, for the third quarter of 2002. Ixia's third quarter GAAP results included non-cash charges of $893,000 for the amortization of acquisition related intangible assets, $397,000 for stock-based compensation and a tax benefit of $582,000 associated with these items. Excluding the effects of these items, non-GAAP net income was $3.1 million, or $0.05 per diluted share, compared to $2.4 million, or $0.04 per diluted share, for the same period last year. "Revenues increased 8.0% over the prior quarter as we continued to expand our market opportunity and add new customers," commented Errol Ginsberg, President and Chief Executive Officer of Ixia. "Growth was driven by our 10 Gig product line and software sales of ANVL and Chariot, as well as continuing demand for our Ethernet TXS cards. A solid performance domestically with customers such as Ciena, Cisco, Hewlett Packard and Motorola was complemented by a strong performance in the Asia Pacific region. Last year, we restructured our sales effort in this important region, and revenues for the quarter have shown healthy increases in China, Japan, Korea and Taiwan among other key markets." "The integration of the Chariot product line is on track and sales of Chariot are ahead of schedule," Mr. Ginsberg added. "During the quarter, we added an impressive 93 new customers, largely due to the acquisition. We are having success selling Chariot and our other software products into our core customer base of network equipment manufacturers and carriers, while expanding into the enterprise market with leading companies like Edward Jones, Enterprise Rent-A-Car and Mary Kay. Importantly, many of these customers are purchasing both hardware and software products from Ixia. Non-GAAP gross margins were impacted by the royalty payment related to the acquisition, but remained strong." During the quarter, Ixia acquired a perpetual license to the source code for the Chariot product line from NetIQ Corporation and the exclusive U.S. and Canadian distribution rights through December 31, 2004 for $17.5 million, plus royalties on sales of the existing Chariot product. Ixia has an option to purchase for $2.5 million the remaining assets of the Chariot product line after December 31, 2004. As of September 30, 2003, Ixia had approximately $117.6 million in cash and investments with no debt.
