U.S. lawmakers are advancing the MATCH Act to pressure allies into aligning with American export controls on China. The legislation specifically targets ASML's Deep Ultraviolet (DUV) lithography systems and related services.
This legislative push arrives as ASML prepares to release its second-quarter earnings. China accounted for approximately one-third of ASML's total sales in 2025.
Projections suggest China’s revenue contribution will drop to 20% by 2026. Investors are monitoring the company's guidance for risks associated with these proposed regulatory changes.
