AMSTERDAM, June 19, 2026, 14:08 CEST
- ASML shares in Amsterdam slipped 0.6% to €1,666.00 at 13:37 CEST. The stock earlier hit €1,631.40.
- The company said it did not ship EUV chipmaking machines or EUV parts to China, pushing back after a Bloomberg report outlined U.S. worries.
- The move cuts into a strong AI-driven run for chip-equipment stocks. ASML’s U.S. shares aren’t trading because of the Juneteenth holiday.
ASML Holding shares fell in Amsterdam Friday after the chip-equipment giant said it has not shipped its top-end lithography technology to China. The move raised new export-control questions, hitting one of Europe’s biggest AI-related stock rallies. Shares were down 0.6% at €1,666.00 at 13:37 CEST, after touching an intraday low of €1,631.40, according to Google Finance.
ASML holds a key spot in the semiconductor supply chain. Extreme ultraviolet lithography, known as EUV, relies on short-wavelength light to form the fine circuit patterns for top-tier chips. ASML is the only company that sells commercial EUV machines, Reuters said earlier this year.
ASML told Reuters it “never shipped an EUV machine to China” and said it hadn’t sent components, modules or equipment made for EUV systems to China either. Earlier, Bloomberg News reported that U.S. Commerce Secretary Howard Lutnick voiced concerns to ASML execs that a machine may have made its way to China, possibly breaching U.S.-driven export limits.

ASML’s stock held up. The key is it didn’t break down. Shares in Amsterdam lost ground Friday but stayed near the 52-week high of €1,669. The stock is still up a lot this year as bets on AI infrastructure keep demand strong.
Euronext says its cash and derivatives markets are open Monday through Friday in 2026, except on listed holidays, with Amsterdam trading running through June. ASML’s Nasdaq shares will not trade in regular U.S. hours on Friday, as Nasdaq is closed June 19, 2026, for Juneteenth. Euronext
ASML faces new worries even as orders remain strong. In April, the company posted first-quarter net sales of €8.8 billion with net income hitting €2.8 billion, and it forecast 2026 net sales between €36 billion and €40 billion. CEO Christophe Fouquet said, “Demand for chips is outpacing supply” and noted customers are speeding up capacity plans. ASML
Chip equipment names moved together this week. Applied Materials, Lam Research and KLA all bounced after Citi analyst Atif Malik raised his wafer-fabrication equipment outlook, pointing to AI demand. ASML dropped, but that looked tied to policy, not a shift in chipmaker demand.
The risk isn’t small here. Tighter Dutch licensing on U.S. pressure could hit ASML’s China business harder, with more curbs on sales and service possible. Reuters said in April that China made up 33% of ASML revenue in 2025, but ASML expects that to drop to 20% this year. The company has already baked in “potential outcomes” from export-control talks in its guidance range. Reuters
Investors seem willing to separate the allegation, which ASML has denied, from the bigger AI spending theme they still favor. But that divide could shift fast. A U.S. ruling, changes to Dutch export rules, or signs of slower tool orders from customers could turn Friday’s drop into more than just a blip, and start a real shift on geopolitical risk.
