ASML Faces Its Most Complex Test Yet: Record Guidance Meets a Chinese Rival's First Steps

ASML faces a divided narrative: raised 2026 revenue forecast vs. Chinese competitor Aishengna's immersion DUV debut, sending shares down 20.68% from 52-week high.

The lithography giant ASML is navigating an increasingly divided narrative. On one side sits a freshly raised revenue forecast and a deepening moat in cutting-edge EUV technology. On the other, a Chinese competitor has quietly begun serial production of immersion DUV machines — a development that sent the stock sliding 5.03 percent on Tuesday, extending its weekly decline to 12.05 percent. The shares closed at €1,390.40, now 20.68 percent below the 52-week high of €1,748.00 reached in June.

The Numbers Tell Two Stories

Just weeks ago, the picture looked unambiguously bullish. On July 15, ASML reported second-quarter net revenue of €9.3 billion with a gross margin of 54.0 percent. Management used the strong results to lift the full-year 2026 revenue forecast sharply, from a prior range of €36 billion to €40 billion up to €43 billion to €45 billion. That upgrade should have been a clear catalyst. Instead, it was quickly overshadowed by news out of Shanghai.

On July 28, reports emerged that Shanghai Aishengna Electronic Technology Group — a state-backed entity — had begun limited serial production of immersion DUV systems modeled on ASML's Twinscan NXT:1950i, a design that dates back to 2008. The technology is roughly two decades old by ASML's standards, but the symbolic weight is considerable. For the first time, China has a functioning domestic alternative in the lithography segment that matters most for mainstream chip production.

Aishengna plans to deliver five machines this year and scale to 20 units annually by 2027. To put that in perspective, ASML shipped 131 DUV systems in 2025 alone. The volume gap remains enormous. Yet the risk is not about immediate market share loss — it is about the precedent. Western export controls, which have barred ASML from selling its most advanced DUV and EUV tools to China, have effectively incentivized the very competition they were designed to prevent.

The China Revenue Question

That dynamic is already reshaping ASML's geographic revenue mix. China's share of ASML's total revenue is expected to fall to roughly 20 percent in 2026, down from 33 percent the prior year. In absolute terms, that still represents about €9 billion — a meaningful chunk of the company's top line. If domestic Chinese foundries such as SMIC and Hua Hong increasingly turn to local equipment, particularly under the threat of additional US restrictions like the proposed MATCH Act, ASML's dependable volume business in China could come under sustained pressure.

The market is pricing in that anxiety. The stock has fallen 15.48 percent over the past 30 days, and the relative strength index has dropped to 36.4, approaching oversold territory. The 50-day moving average of €1,535.12 now sits 9.43 percent above the current price — a clear sign that short-term momentum has turned decisively negative. Annualized 30-day volatility has spiked to 55.80 percent, reflecting the heightened sensitivity around any perceived threat to ASML's growth narrative.

Why the Bulls Aren't Backing Down

For all the China-driven jitters, the longer-term technical picture still favors the optimists. The stock remains 16.43 percent above its 200-day moving average of €1,194.15, and the 12-month gain stands at 123.18 percent. The structural bull case rests on a single, powerful argument: ASML's monopoly in high-NA EUV lithography, the technology required for the most advanced logic and memory chips.

Intel Foundry recently confirmed that it has begun high-volume manufacturing on its 18A node using ASML's high-NA EUV systems — a world first. That achievement underscores the vast technological distance between ASML's current frontier and what Chinese rivals can replicate. Aishengna is building machines from 2008; ASML is selling tools that no one else can build at all.

The company is doubling down on that lead. ASML plans to expand EUV production capacity by 30 percent in 2027 and is evaluating a further 30 percent increase for 2028, driven by insatiable demand from AI infrastructure buildout. Bank of America and JPMorgan have argued that the China threat remains manageable in the medium term: building a few dozen machines is fundamentally different from achieving reliable, high-yield mass production at scale.

The Bear Case: Erosion, Not Collapse

The counterargument is more gradual but no less unsettling. If China can replicate even older-generation DUV technology at scale, it chips away at ASML's pricing power and market share in the segment that generates the bulk of its unit volumes. The nightmare scenario, as some analysts describe it, is that once the DUV monopoly is broken, margin pressure becomes a one-way street — even if high-NA EUV remains uncontested at the top end.

The key question for investors is whether the ultra-high-end business can more than compensate for creeping losses in the DUV mass market. A sustained recovery depends on ASML demonstrating that its high-NA EUV expansion can offset any Chinese market share erosion. The next concrete test will come with the third-quarter earnings report and further updates on the 2027 capacity roadmap.

What to Watch Next

Technically, the stock is approaching levels that have historically attracted buyers. If the RSI falls decisively below 30, a short-term stabilization would be plausible — barring any escalation in export controls from Dutch or US authorities. A break below the 200-day moving average of €1,194.15 would signal a more fundamental reassessment of geopolitical risk. The 52-week low of €588.00 remains far below, but that gap itself highlights how much optimism is still baked into the current valuation.

For now, ASML is caught between two realities: a record order book and a competitor that, however small, now exists. The era of ASML as a one-way bet on global chip hunger is over. What replaces it is a more complex story — one where technological leadership and geopolitical friction are no longer separate variables, but increasingly the same equation.
