ASML's stock is down ~25% in the past year from a record ~€1,000 in July 2024, cutting $130B+ from its market cap, amid China export rules and US tariffs
More than $130 billion of value has been wiped off of ASML in under a year amid restrictions on exports to China and U.S. tariff uncertainty
Context & Ripple Effects
ASML entered this period with unusually high exposure to China: the country had been its largest market for four straight quarters, including nearly half of quarterly sales in early 2024 (China’s run as ASML’s largest market). That concentration makes export-policy changes especially material to the company’s outlook.
The share decline also follows an earlier reset in expectations, when ASML’s 2025 sales outlook triggered its sharpest stock fall since 1998 (the earlier 2025-demand forecast reset). The latest loss shows geopolitical uncertainty has become an additional valuation constraint alongside the semiconductor-cycle outlook.
First-order effects
- ASML shareholders absorb a further reduction in market value as China export restrictions and U.S. tariff uncertainty widen the range of potential revenue and demand outcomes.
- ASML must plan production, customer support and guidance against less predictable access to a market that had accounted for a large share of its sales.
Second-order effects
- Chipmakers and equipment buyers may delay or re-sequence capacity decisions while they assess tariff exposure and the availability of ASML tools, making order timing less reliable for the equipment supply chain.
- Investors are likely to apply a larger geopolitical-risk discount to ASML and other semiconductor companies with material China exposure, reinforcing the sensitivity seen after ASML’s prior weak 2025 outlook.
Third-order effects
- If export controls and tariff uncertainty persist, semiconductor-equipment demand could become more geographically segmented, with supplier growth increasingly determined by market access rather than technical demand alone.
- The episode points to a more contracted semiconductor cycle in which policy risk can interrupt long equipment-planning cycles; the extent depends on how durable the restrictions and tariff regime prove to be.
The trend: Semiconductor capital-equipment valuations are increasingly being shaped by the intersection of China market access, trade policy and long-cycle fab investment.
