Munich (euro adhoc) - February 15, 2007 - According to its
preliminary business results for fiscal 2006, Wacker Chemie AG saw a
record year in terms of sales and earnings. Driven by capacity
additions, a positive environment for semiconductor wafers and a
strong demand in most segments, consolidated Group sales went up by
21 percent to some EUR3.33 billion (2005: EUR2.76 billion). EBITDA
(Earnings before Interest, Tax, Depreciations and Amortization) grew
even faster at 38 percent to some EUR785 million (2005, adjusted:
EUR567 million).

Q4 2006 saw stronger results than in the previous year. Based on a
solid pricing environment, Siltronic achieved an EBITDA-Margin in the
fourth quarter of 33 percent, up from 30 percent in Q3 2006, and up
from 27 percent in Q4 2005. For the full year, Siltronic’s sales are
expected to reach some EUR1.26 billion (2005: EUR925 million), while
EBITDA is estimated to come in at around EUR355 million (2005,
adjusted: EUR153 million).

WACKER POLYSILICON benefited from the availability of additional
material from the finalization of its Poly 4 expansion stage, which
helped to drive up production volumes to 6,200 metric tons for the
full year 2006. Preliminary results indicate full-year divisional
sales of around EUR325 million (2005: EUR288 million), EBITDA is
expected to reach some EUR115 million (2005: EUR90 million).

The chemicals divisions saw in Q4 the expected seasonal downturn.
However, this trend has been balanced to a certain extent by a strong
demand for WACKER’s silicone and polymer products from the
construction sector due to the mild winter conditions. The chemicals
divisions’ 2006 full-year sales are estimated to reach around EUR1.95
billion (2005: EUR1.70 billion) while EBITDA is expected to come in
at some EUR 345 million (2005: EUR328 million).

Earnings per share for 2006 are expected to come in at about EUR6.40
based on a tax rate of around 25 percent. In 2005, WACKER Group had
earned EUR2.90 per share outstanding.

WACKER Group CFO Joachim Rauhut commented: "In its first year at the
stock exchange, WACKER achieved a return on capital employed of some
18 percent, thus setting a new all time high. We consider our strong
2006 results combined with our leading market positions and capacity
additions running on schedule as an excellent foundation for the
Group’s further sales and earnings growth in the current fiscal
year."

It should be noted that indicated results for the fourth quarter and
the full year 2006 are preliminary. WACKER’s actual results for the
fourth quarter and the full year 2006 will be reported on March 22,
2007.
