Negative one-time effect originating from its subsidiary SMI

Restructuring and Adjustments

Dortmund: In order to make use of market opportunities for
Microsystems in a better and more effective way in the future, ELMOS
Semiconductor AG has implemented recently a new board of management
at its U.S. subsidiary Silicon Microstructures Inc. (SMI) in
Milpitas, California. In the meantime the new management conducted a
thorough investigation and identified a need for restructuring and
adjustments for 2007.

This has implications also for the Dutch subsidiary ELMOS Advanced
Packaging B.V. (ELAP) in Nijmegen, Netherlands, because of a
significantly delayed production start of SMI products, which should
have been assembled in the Netherlands. As a consequence of that, the
actual headcount at ELAP will be reduced by 50 people.

The necessary expenses for restructuring and adjustments amount to
approximately 5.6 Mio Euro for the ELMOS group. Approximately 3.9 Mio
Euro of these one-time cost will impact the profit & loss statement
of the first quarter 2007, the remaining portion will result in an
increase of expenses for the rest of the current year.

The actual guidance for sales in 2007 remains unchanged. When the
above mentioned one-time effects would be neglected, the
margin-guidance for standard course of operations would remain
unchanged. Taken these extra cost into account will decrease the
margins by approximately 3 percent points.

The Management board of ELMOS Semiconductor AG will report on the
situation and the measures taken during a conference call on
Wednesday, April 25th 2007, at 4 pm CEST.
