ASML shares declined by approximately 2.6% following the introduction of the MATCH Act by U.S. lawmakers, which aims to impose stricter export controls on chipmaking tools to China. This bipartisan proposal could significantly impact ASML’s sales in the region, where the company projected 20% of its total revenue for the year, down from 33% by 2025. The MATCH Act specifically targets DUV lithography machines, which are essential for producing less advanced semiconductors that Chinese manufacturers still rely on.

The implications of these restrictions could be profound, as ASML has never exported its advanced EUV machines to China, but the proposed ban on DUV tools could lead to a notable revenue hit—estimated at around 5%—given that China accounts for about half of the sales from this segment. Analysts suggest that while the legislation is still in early stages, its potential passage creates uncertainty and could lead to volatility in ASML’s financial results.

Market professionals should monitor the legislative developments closely, as any definitive action on the MATCH Act could disrupt ASML’s supply chain and sales trajectory, particularly in the context of China’s ongoing efforts to bolster its domestic semiconductor industry.
