Why is Wacker Chemie stock sliding today?

Wacker Chemie, a Munich-based chemicals group, saw its stock dip by 2.8% to €92.13 after a Reuters exclusive reported the company is considering shutting down its Charleston, Tennessee polysilicon facility. The facility, which employs around 600 workers, is facing potential closure due to the loss of both of its remaining customers.

This comes after the White House announced a price floor and tariff on imported polysilicon on August 6, a policy that failed to differentiate between foreign-made and domestic material, making Wacker's American plant commercially unviable. The company stated that while it is in talks with the administration, the current proclamation does not effectively support the use of U.S. made polysilicon.

CEO Christian Hartel had previously warned investors that the company might have "one plant too many" if the anticipated trade action did not provide meaningful support. The broader analyst community remains cautious, with the stock's consensus rating at Neutral and the average price target below current levels. The news comes at a challenging time for Wacker's polysilicon business, as the company's CEO had previously cautioned about the potential need to reduce the number of plants.

The broader European equities market was also pressured on September 3, with Frankfurt markets recording losses due to rising bond yields, elevated oil prices, and persistent inflation concerns. Meanwhile, U.S. markets were modestly in the red, providing no support to European industrials or materials names. Other specialty chemicals peers with polysilicon or solar-supply-chain exposure are also facing similar headwinds from the unresolved U.S.-China trade dynamic.

The sharp intraday move in Wacker Chemie's stock can be attributed to a high-profile and unexpected operational risk, the potential write-off of a $2.5 billion U.S. asset, combined with a soft macro environment and the stock trading below its 52-week high of €105.60.
