“The leading market positions and strict cost management are the basis for this gratifying performance. It is supported by a favorable market environment”, said Peter Bauer, CEO of Infineon Technologies AG.

In the forecast for the 2009/10 financial year that was published on January 29, 2010, the company expected a year-on-year growth in revenues of over 20 percent and a high single-figure Segment Result margin. For the second quarter of the current financial year, Infineon expected revenues at the same level as in the first quarter or even slightly lower due to seasonality.
