ASML Shares Drop Following US Proposal to Restrict Semiconductor Exports to China

The proposed MATCH Act could significantly impact global semiconductor supply chains and the competitive landscape, particularly for companies reliant on Chinese markets.

• ASML shares fell up to 4.7% in Amsterdam trading on April 7, 2026, following news of the MATCH Act proposal.
• The MATCH Act aims to restrict exports of semiconductor manufacturing equipment to China, targeting major firms like SMIC and Huawei.
• China accounted for 33% of ASML's sales in 2025, with projections indicating a drop to 20% in 2026 due to ongoing restrictions.

• ASML Holding NV is a key player in the semiconductor equipment market, holding a near-monopoly on advanced lithography systems essential for chip production.
• US-led export controls have escalated in recent years, initially blocking extreme ultraviolet (EUV) tools while allowing deep ultraviolet (DUV) sales, which have sustained Chinese chipmaking capabilities.
• The geopolitical landscape is marked by a US-China tech rivalry, with bipartisan support in Congress to tighten controls on technology that could enhance China's semiconductor industry.

On April 3, 2026, a bipartisan group of US lawmakers introduced the MATCH Act, aiming to prohibit the export, sale, and servicing of semiconductor manufacturing equipment to China. This legislation is particularly focused on deep ultraviolet (DUV) lithography systems, which are crucial for producing advanced chips. The bill is designed to align multilateral technology controls and prevent entities benefiting from US CHIPS Act funds from engaging with Chinese firms like SMIC, Huawei, and YMTC.

The immediate market reaction was swift; ASML shares dropped as much as 4.7% intraday before closing 4.1% lower at 1,114 euros. This decline reflects investor concerns about the potential impact of the MATCH Act on ASML's revenue, given that China represented a significant portion of its sales—33% in 2025. Analysts have estimated that if the MATCH Act is enacted, ASML could face a low double-digit percentage hit to its earnings.

The MATCH Act is part of a broader strategy by the US government to curb China's technological advancements and maintain its competitive edge in the semiconductor industry. The legislation is seen as a response to fears that Chinese firms could leverage advanced technologies to enhance their capabilities, potentially posing a threat to US national security and economic interests.

European chip equipment peers, such as ASM International and BE Semiconductor, also experienced declines in their stock prices, indicating a wider market concern about the implications of the MATCH Act. The reaction from Chinese state media has been critical, labeling the US actions as hegemonic and indicative of a broader decoupling between the two largest economies in the world.

As the geopolitical climate continues to evolve, the semiconductor industry remains at the forefront of tensions between the US and China. The MATCH Act is just one of many measures aimed at limiting China's access to critical technologies, which could reshape global supply chains and alter the competitive landscape in the tech sector.

• Investors in ASML: Immediate financial impact due to stock price decline.
• Chinese chipmakers (SMIC, Huawei, YMTC): Directly affected by restricted access to essential manufacturing equipment.
• European semiconductor equipment manufacturers: Potential revenue impacts as market sentiment shifts.
• US tech firms: Companies relying on Chinese markets may face supply chain disruptions and revenue declines.
• Global supply chain stakeholders: Increased uncertainty in semiconductor availability could affect various industries reliant on chips.

• Legislative progress on the MATCH Act: Monitoring how quickly this proposal moves through Congress will indicate the urgency of US-China tech tensions.
• Market reactions from other semiconductor firms: Observing stock price movements of competitors could signal broader industry sentiment and potential ripple effects.
• Chinese government responses: Any retaliatory measures or policy changes from China could impact global supply chains and market dynamics.
