KEY POINTS
- ASML posted Q1 net sales of €8.8 billion and net income of €2.8 billion, both above consensus, and raised its 2026 revenue guidance to €36–€40 billion.
- China system sales collapsed to 19% of revenue from 36% in Q4, as a proposed U.S. bill threatens to cut off remaining DUV shipments to Chinese fabs.
- Traders should watch the Q2 gross margin guide of 51%–52%, which signals mix pressure from fewer high-margin China orders, and the legislative timeline on the new DUV export bill.
ASML delivered €8.8 billion in first-quarter net sales, beating the €8.5 billion consensus by a comfortable margin, and raised its full-year 2026 revenue guidance to €36–€40 billion from the prior €34–€39 billion range. Net income came in at €2.8 billion against expectations of €2.5 billion. On any other day, those numbers would have sent the stock higher. Instead, ASML shares fell 6% on Wednesday as the market zeroed in on a number that mattered more than the beat: China.
System sales to China dropped to 19% of overall revenue in Q1, down from 36% in the December quarter. That is not a seasonal blip. It reflects a deliberate, policy-driven contraction that is only getting more aggressive.
The Tightening Noose on China Sales
A bipartisan group of U.S. lawmakers introduced legislation in April that would prohibit ASML from selling its older deep-ultraviolet (DUV) lithography machines to Chinese semiconductor companies. If enacted, the bill would effectively close the last major loophole in the Western chip-equipment blockade. Current export controls already bar the sale of ASML's most advanced extreme-ultraviolet (EUV) systems to China, but DUV tools, which can still produce chips at mature and semi-advanced nodes, have remained a significant revenue stream.
ASML CEO Christophe Fouquet addressed the issue directly on the earnings call, acknowledging "increased uncertainty" around China but emphasizing that the company's order backlog remains strong enough to support the raised guidance. The backlog, which stood at €55 billion at the end of Q1, is dominated by EUV orders from non-Chinese customers investing in leading-edge fab capacity. That backlog provides visibility, but it does not fully offset the margin impact of losing China business.
The Margin Squeeze Is Real
ASML guided Q2 gross margin to 51%–52%, a sequential decline from the 53% achieved in Q1. The math behind the compression is straightforward: China orders historically carried above-average margins because they skewed toward higher-priced systems and came with service contracts. As that mix shrinks, blended margins come under pressure even as total revenue grows.
For a company trading at roughly 35 times forward earnings after a 40% year-to-date run, the margin trajectory is not a trivial concern. Investors who bought the AI infrastructure thesis at the start of 2026 are now confronting the reality that ASML's growth story has a geopolitical ceiling on one side and margin headwinds on the other.
The company's competitive position remains unassailable. No other firm on the planet can produce EUV lithography systems, and every advanced-node fab expansion underway, from TSMC's Arizona plants to Intel's Ohio buildout to Samsung's Texas facility, requires ASML equipment. The €55 billion backlog reflects that monopoly. But monopoly pricing power and monopoly unit economics are two different things when the highest-margin customer is being regulated out of the order book.
What Traders Should Watch
Three catalysts will determine whether the 6% post-earnings selloff was an overreaction or a warning. First, the legislative timeline on the DUV export bill. If it moves through committee quickly, the market will reprice ASML's China revenue to near zero for 2027 and beyond. Second, the Q2 earnings report will reveal whether the gross margin compression stabilizes at 51%–52% or accelerates further. Third, the pace of EUV order intake from non-Chinese customers. If TSMC, Intel, and Samsung accelerate their build plans to fill the gap left by China, ASML's revenue line holds; if those customers delay, the backlog drawdown becomes the story.
The broader read for the semiconductor equipment sector is that the bifurcation of the global chip supply chain is no longer a theoretical risk. It is showing up in quarterly revenue splits and margin guides. ASML remains the best-positioned company in the world to benefit from the AI buildout. The question is whether the geopolitical discount the market is applying is too large, too small, or just right. At current levels, the stock is pricing in growth without China. If that assumption holds, the 6% dip looks like a buying opportunity. If it does not, there is more room to fall.
