ASML Stock Plummets Amid China Export Control Concerns

ASML shares tumbled 7.82% to $1,778.46, significantly underperforming broader market indices as U.S. lawmakers advanced a bill that could block critical chipmaking equipment exports to China. The proposed restrictions target deep-ultraviolet lithography (DUV) systems, which represent a key revenue stream for the Dutch semiconductor firm.

China accounts for approximately 20% of ASML's projected 2026 revenue, amplifying investor concerns about the potential financial impact. While Wells Fargo maintained confidence with a $2,200 price target, market sentiment remains cautious as regulatory scrutiny intensifies.

The selloff reflects growing geopolitical tensions in the tech sector, with semiconductor equipment becoming a focal point in U.S.-China trade relations. ASML's denial of prior export violations did little to assuage fears about future restrictions on software updates and maintenance services for existing Chinese clients.
