A more positive market environment for semiconductor equipment, an expanded customer range following the integration of Genus, Inc., and improving demand for newly launched products increased 2006 AIXTRON Group revenues by 23% to EUR 171.7 million. As a result of the revenue increase, and following the successful review of costs and operating practices, AIXTRON generated a net income after tax of EUR 5.9 million in 2006.

The value of compound equipment orders, received by AIXTRON in 2006, rose by 79 %, compared to 2005, to EUR 136.8 million, reflecting a significant mid-year rise in demand from LED end-application markets. Based on robust demand for CVD equipment for memory applications, the value of orders received for silicon semiconductor equipment also increased by 11 % year over year, to EUR 41.2 million in 2006.

Management Review

Paul Hyland, President and Chief Executive Officer at AIXTRON, commented: 'The increase in the depth and breadth of our business following the integration of Genus, Inc., and the focus on cost and efficiency have been key elements in producing the positive 2006 financial results. Working off this foundation and with an encouraging outlook, we believe we can further establish profitable growth during the coming year.'

Outlook

AIXTRON believes that 2007 revenues will remain at a healthy level both for the compound and silicon semiconductor applications. Taking into consideration the healthy order backlog as per December 31, 2006 of EUR 85.1 million, the Company expects sales revenues in a range of EUR 190 million and EUR 200 million and EBIT of EUR 15 million and EUR 16 million for fiscal year 2007.
