U.S. Lawmakers Introduce Bill Targeting ASML to Tighten Export Controls on Semiconductor Equipment

ASML
April 03, 2026

The House of Representatives introduced the Multilateral Alignment of Technology Controls on Hardware (MATCH) Act on April 3 2026, a bipartisan bill that explicitly names ASML Holding N.V. as a target. The legislation seeks to broaden existing U.S. export restrictions on semiconductor equipment sold to China, with a particular focus on immersion deep‑ultraviolet (DUV) lithography machines that ASML dominates.

The MATCH Act would extend the scope of the current export controls by adding new end‑user restrictions and service limitations for immersion DUV systems. It also aligns Dutch export controls with U.S. policy, ensuring that allied suppliers face comparable curbs. The bill follows a series of U.S. export‑control rounds since 2022 and Dutch tightening of controls, reflecting a coordinated effort to limit China’s access to advanced chip‑making tools.

ASML’s exposure to China is substantial. In the fourth quarter of 2025, China accounted for 36 % of the company’s net system sales, and the 2025 full‑year revenue from China was €10.2 billion, representing 36.1 % of global sales. The company’s China share is expected to normalize to roughly 20‑25 % in 2025 due to existing restrictions, and it forecasts that China will comprise about 20 % of 2026 revenue. These figures illustrate the potential revenue impact if the MATCH Act further limits sales to the Chinese market.

Financially, ASML reported Q4 2025 net sales of €9.7 billion with a gross margin of 52.2 % and net income of €2.8 billion. The full‑year 2025 results were €32.7 billion in net sales, 52.8 % gross margin, and €9.6 billion in net income. For 2026, the company projects net sales of €34‑39 billion and a gross margin of 51‑53 %. CEO Christophe Fouquet has emphasized that while China demand will be lower in 2026 than in 2024‑25, the company does not expect overall 2026 net sales to fall below 2025 levels.

The bill’s passage would likely reduce ASML’s revenue from China and could shift its market share dynamics, as China is currently its largest customer base. The broader U.S. strategy aims to curb China’s semiconductor capabilities, and the MATCH Act would formalize and potentially broaden the restrictions. For ASML, the legislation underscores the geopolitical risks that can affect its top‑line growth and highlights the importance of diversifying its customer mix beyond China.

The introduction of the MATCH Act marks a significant escalation in U.S. export‑control policy toward China’s semiconductor industry. If enacted, the bill would tighten the regulatory environment for ASML’s immersion DUV systems and reinforce the alignment of Dutch controls with U.S. policy, potentially reshaping the company’s revenue profile and strategic priorities for the coming years.
