Wacker Chemie shares declined 2.8% to trade at 82.13 after a report disclosed that the Munich-based chemicals producer is considering shutting its Charleston, Tennessee polysilicon plant, which employs roughly 600 workers, following the loss of its two remaining customers.
The customer exits came after a White House proclamation on August 6 that established a price floor and tariff on imported polysilicon. According to the company, the measure - as currently written - does not effectively distinguish between foreign-made and domestically produced polysilicon, leaving the U.S. plant commercially unviable.
Wacker declined to comment directly on the customer departures but confirmed the administration's proclamation "does not, as it reads now, effectively support the use of U.S. made polysilicon," and said it is engaged in active discussions with the administration to seek a workable solution.
The development compounds pre-existing challenges for Wacker's polysilicon business. Chief Executive Officer Christian Hartel had warned investors only days before the August proclamation that the company could find itself with "one plant too many" if any trade action failed to provide meaningful support. The Charleston facility had already seen job reductions in the prior year.
Analyst sentiment on the stock is cautious. The consensus rating sits at Neutral and the average price target is below the current share price, leaving limited cushion for unexpected negative news such as the potential closure. Market participants noted the combination of a high-profile operational risk - including the possibility of writing off a $2.5 billion U.S. asset - alongside a soft macroeconomic backdrop as key drivers of the share move.
Market conditions offered little offset to the headline risk. European equities opened September under pressure, with Frankfurt markets posting losses on September 3 as rising bond yields, elevated oil prices and persistent inflation concerns weighed on investor sentiment across the region. U.S. markets were also modestly lower on the day, with both the S&P 500 and the Dow Jones trading fractionally down, providing no positive momentum for European industrials or materials names.
Peers in the specialty chemicals and solar supply chain that have exposure to polysilicon are facing similar headwinds, influenced by the unresolved trade dynamic between the U.S. and China. That sector-level pressure amplified the stock reaction when Wacker's shares hit an intraday low of 88.50 before recovering partially to the reported 82.13 level.
In summary, the reported loss of customers at the Charleston polysilicon site, the current limitations of U.S. trade policy as described by the company, the CEO's earlier warning about excess capacity, and unfavorable market conditions together explain the stock's sharp intraday decline.
Context and next steps
Wacker says it is in active discussions with the U.S. administration to seek adjustments that would make U.S.-made polysilicon commercially viable under the new policy framework. The company has otherwise declined to comment on the customer departures themselves.
Investors and sector watchers will likely focus on any clarifications from the administration or new commercial arrangements for the Charleston facility as indicators of whether the plant can be preserved or will be written down.
