Production Capacity Expansion

09.12.2010

Munich, December 9, 2010 - Wacker Chemie AG will build a new and
fully integrated polysilicon-production site near the city of
Cleveland, Tennessee (USA). The Munich-based chemical company
announced the decision today. With an annual capacity of 15,000
metric tons, the production complex will be built on a property
acquired by WACKER early last year. In Cleveland, WACKER will build
facilities that are based on closed-loop material recycling for the
entire polysilicon-production supply chain. This spans from the
production of trichlorosilane feedstock and deposition of hyperpure
silicon through to facilities to recycle resultant by-products and
auxiliary materials. The new site´s completion is expected at the end
of 2013. The Group has budgeted investments of some EUR1.1 billion
for this expansion of its production capacities. As a result, around
650 new jobs are expected to be created in Cleveland.

This investment decision will enable WACKER to meet the accelerating
global demand it expects for hyperpure polycrystalline silicon. For
coming years, WACKER anticipates continued double-digit annual growth
in polysilicon demand by the solar-industry. The company likewise
expects higher polysilicon demand from the electronics sector.

With a production output of some 30,000 metric tons in 2010, WACKER
is the world´s second-largest producer of hyperpure polycrystalline
silicon. WACKER´s polysilicon production currently under construction
in Nünchritz (Germany) and the new capacities at its Tennessee site
are reinforcing the Group´s position as a leading manufacturer of
high-quality semiconductor and solar silicon.
