Infineon Technologies raises guidance for third quarter financials

Neubiberg, Germany – June 25, 2009 – Infineon Technologies today raised the guidance for the third quarter of the 2009 fiscal year. For the current third quarter of the 2009 fiscal year Infineon now expects a Combined Segment Result approaching break-even with revenues increasing by a low-teens percentage sequentially. In addition, Infineon anticipates free cash flow to be clearly positive and foresees a gross cash position approaching Euro 850 million for the end of the quarter. When the company originally provided the market with an outlook for the third quarter of the 2009 fiscal year on 30 April 2009, Infineon expected revenues to increase by about 10 percent sequentially with a negative mid to high single digit Segment Result margin. “Despite the adverse overall economic climate and the difficult semiconductor market environment, our Combined Segment Result should approach break-even. This improvement along with the favorable liquidity development are impressive evidence for the success of our operative performance, cost reduction and cash preservation measures”, said Peter Bauer, CEO of Infineon Technologies AG.
