Net revenues for the third quarter of 2004 increased 39% on a year-over-year basis and 12% sequentially, to $30.1 million, the highest total in the Company's history. Net income on a GAAP basis for the third quarter of 2004 was $4.7 million, or $0.07 per diluted share, a 96% increase when compared to $2.4 million or $0.04 per diluted share, for the third quarter of 2003. Ixia's third quarter of 2004 GAAP results included $1.2 million of non-cash charges related to the amortization of acquired intangible assets and stock-based compensation, and associated income tax benefit of $503,000. Excluding the effects of these items, non-GAAP net income was $5.5 million, or $0.09 per diluted share, compared to $3.1 million, or $0.05 per diluted share, for the same period last year after excluding the effects of similar items. "Our record top-line performance reflects strong momentum for our product lines, as bookings were the highest in the Company's history," commented Errol Ginsberg, 4 President and Chief Executive Officer of Ixia. "While the market for IT spending remains challenging, this growth reflects the success of our R&D efforts, our strategic acquisitions and the rapid expansion of our core Ethernet business. During the quarter, we grew sales of our 1 Gig TXS load modules by 30% sequentially, as the market demand continues to grow for these advanced Ethernet test solutions capable of running complex applications. Solid demand for 10 Gig products was another key factor in our record quarterly performance in a normally seasonally softer period." "Ixia is also succeeding in diversifying its products and customer base thus expanding our addressable market opportunity. Software continues to help drive sales of our TXS cards, accounting for approximately $4 million in sales, up 45% from last year. The third quarter was also highlighted by encouraging results in the government market. Our new dedicated sales team is performing well and we were pleased with a number of wins in this area." During the third quarter ended September 30, 2004, Ixia increased cash, cash equivalents and investments by $2.3 million to approximately $128.1 million. Ixia will host a conference call today for analysts and investors to discuss its quarterly results at 5:00 p.m. Eastern Time. Open to the public, a live Web cast of the conference call will be accessible from the "Investors" section of Ixia's Web site (www.ixiacom.com). Following the live Web cast, an archived version will be available in the "Investors" section on the Ixia Web site for 90 days.
