ASML (ASML) stock came under pressure in early trading after US lawmakers introduced new bipartisan legislation aimed at tightening global controls on semiconductor manufacturing equipment sales to China. The move adds fresh uncertainty for one of the world’s most critical chip equipment suppliers, as investors assess how far-reaching the proposed restrictions could become.
The proposed bill, known as the Multilateral Alignment of Technology Controls on Hardware (MATCH Act), seeks to extend US export restrictions beyond domestic firms to include allied suppliers such as ASML and Tokyo Electron. The legislation reflects growing efforts in Washington to close regulatory gaps that have allowed China to continue accessing advanced chipmaking technologies through non-US channels.
Stronger allied alignment push
A key goal of the MATCH Act is to synchronize export control frameworks across allied nations. Currently, US restrictions under tools such as the Entity List apply more aggressively than those in many partner countries, which rely on slower multilateral agreements like the Wassenaar Arrangement. Lawmakers argue these differences have created loopholes that China’s semiconductor industry has exploited.
If passed, the bill would pressure allied governments to align more closely with US export rules, potentially restricting the sale and servicing of advanced chip tools in China. This includes limiting access for engineers servicing equipment already installed in Chinese semiconductor facilities, a step that could significantly disrupt maintenance cycles and production efficiency.
Advanced lithography systems in focus
ASML’s deep ultraviolet (DUV) immersion lithography machines are specifically highlighted in the proposed framework. These systems are essential in producing advanced semiconductors used in artificial intelligence, data centers, and high-performance computing applications.
Under current Dutch export policies, ASML already faces licensing restrictions, but the MATCH Act would further tighten global coordination around these controls. This raises concerns that even indirect or partially regulated sales channels could be affected if allied governments adopt similar measures.
Chinese demand has been a major revenue driver for ASML in recent years. In 2024, Chinese buyers accounted for a significant share of ASML’s deep ultraviolet system shipments, underscoring how important the market has been despite increasing geopolitical friction.
Revenue exposure becomes a concern
Market attention is now shifting toward ASML’s exposure to China. The company has previously forecast that China could account for roughly 20% of its 2026 revenue, down from nearly 30% in 2025. While this signals a gradual reduction in dependency, investors remain cautious about how quickly restrictions could reshape demand.
The semiconductor equipment industry is particularly sensitive to policy shifts because of long sales cycles and heavy reliance on global supply chains. Any tightening of export controls risks delaying orders, reducing servicing revenue, and complicating long-term contracts with manufacturers.
Global chip tensions intensify
The broader geopolitical context is also weighing on sentiment. The proposed legislation reflects a shift from cooperative export policy to a more assertive stance, with the US signaling it may use regulatory tools such as the Foreign Direct Product Rule (FDPR) to extend influence over foreign-made goods that rely on US-origin technology.

Analysts note that this could increase the risk of retaliation from China, which has previously responded to semiconductor-related restrictions by tightening access to critical materials used in global tech manufacturing.
