AMSTERDAM, July 28 (Reuters) - China's launch of a homegrown type of advanced lithography chip printing machine is spotlighting how European chip tool maker ASML, whose recent share price surge made it Europe's most valuable listed company, is being squeezed between two sides.
On the one hand, U.S. controls on exports of high-tech goods to China are threatening to reduce access to a major market; and on the other, Beijing's push for technological independence in areas such as chip production raises the possibility of a China-based competitor.
Reuters reported on Tuesday that a little-known Chinese state-owned firm called Shanghai Aishengna Electronic Technology Group was leading an effort to mass produce locally made immersion deep ultraviolet (DUV) lithography tools, key to modern chipmaking.
ASML, which dominates the market for DUV and more cutting-edge EUV machines that print circuitry on AI chips, saw its shares fall some 10% in two days following this report, enough to wipe more than €60 billion off its stock market value.
Tech news site The Information first reported the Chinese attempt on Monday.
The move spotlights a risk for ASML, whose shares have skyrocketed in the last year and are up around 50% in 2026, with some investors confident it could become Europe's first trillion-dollar firm.
DAMAGE FOR NOW MAY BE LIMITED
ASML has a dominant position in the market for lithography tools, including its mid-range DUV devices. The very best chips require ASML's cutting-edge EUV tools that China cannot currently make or obtain.
The Information said China plans to make five immersion DUV tools this year and 20 in 2027, selling them to major Chinese chipmakers. That remains far below the sales of ASML, which shipped 131 such systems in 2025. So damage even in the medium term will be limited, JPMorgan analysts argued in a note.
"That said, this is another data point in China's equipment self-sufficiency story, and it raises the long-term risk to ASML's China revenue," analysts at the investment bank said.
EXPORT CONTROLS BOOST CASE FOR CHINA-MADE CHIP PRINTERS
Ipek Ozkardeskaya, analyst at Swissquote, was more downbeat, saying that the rise of a Chinese competitor could be a "nightmare scenario" for ASML if it breaks its hold on the DUV market.
ASML said this month it expects 20% of revenue, or around €9 billion worth, will come from China this year.
That's despite rounds of U.S.-led export controls that prevent the firm from selling its most advanced EUV product line in China, as well as its best immersion DUV tools.
Four leading AI models discuss this article
"Short-term share-price reaction exaggerates long-term competitive threat given the still-massive production and technology gap."
ASML's 10% two-day drop after the Shanghai Aishengna DUV news looks overdone. China plans only 5 immersion DUV tools in 2026 and 20 in 2027 versus ASML's 131 shipped in 2025; the gap remains enormous. While Beijing's self-sufficiency push is real and long-term risk to ASML's ~20% China revenue (€9B expected 2026) exists, EUV monopoly and superior DUV performance still lock in high-end AI chip demand. Forward P/E around 35x on 15-20% EPS growth already prices in some China erosion. Missing context: U.S. export controls ironically accelerate Chinese substitution attempts yet simultaneously keep ASML's most profitable EUV line out of reach for Beijing, protecting margins elsewhere.
If Chinese immersion DUV tools achieve even 70% of ASML performance at 40% lower price, domestic chipmakers SMIC, YMTC and CXMT could shift volume rapidly, collapsing ASML's China DUV sales far faster than the article's "limited damage" narrative assumes.
"ASML's competitive edge is defined by total system integration and EUV exclusivity, both of which remain years ahead of any domestic Chinese alternative."
The market's 10% knee-jerk reaction to Shanghai Aishengna’s DUV ambitions is a classic overreaction to headlines, ignoring the immense technical moat ASML maintains. Lithography isn't just about the machine; it’s about the decades-long ecosystem of optics, light sources, and software integration that China’s state-backed firms struggle to replicate at scale. While the 2027 target of 20 units is a credible threat to low-end DUV market share, it doesn't touch ASML’s high-margin EUV dominance. At a forward P/E of roughly 35x, the valuation is stretched, but the fundamental risk isn't an overnight competitor—it's the regulatory ceiling on China-bound revenue, which is already priced in.
If China successfully achieves 'good enough' domestic DUV parity, they could subsidize their domestic chipmakers to abandon ASML entirely, triggering a permanent loss of 20% of ASML's revenue base.
"ASML's China revenue is already constrained by U.S. export controls, so a Chinese competitor threatens market share in a segment ASML couldn't fully serve anyway."
The article frames this as a binary squeeze, but the real story is asymmetric. China's 5 DUV tools in 2026 versus ASML's 131 in 2025 isn't competition—it's a rounding error. The actual threat is structural: U.S. export controls already block ASML's best products from China, so the marginal revenue loss from a Chinese DUV competitor is minimal relative to what's already prohibited. What matters is whether Shanghai Aishengna can scale to 100+ units annually AND achieve acceptable yields/reliability. The 20% China revenue ASML cites (€9B) likely includes legacy sales; forward China revenue may already be capped by geopolitics, not competition. The 10% share drop reflects panic, not fundamentals.
If Chinese DUV tools reach 80% of ASML's performance at 60% of the price within 3-4 years, Chinese chipmakers abandon ASML entirely for mid-range nodes, and ASML's total addressable market shrinks by 30-40% permanently—a scenario the article doesn't quantify.
"Near-term risk to ASML from China appears limited; the real test is whether China can deliver cost-effective, reliable domestic lithography at scale without access to critical Western components."
The headline reads like a clear ASML risk, but the near-term math points the other way. China’s push to mass-produce immersion DUV tools (5 units this year, 20 planned for 2027) signals ambition, not an immediate threat to ASML's lead in EUV. ASML ships far more units in the mid-range DUV than any Chinese rival, and its installed base in China remains a revenue anchor under export controls that already curb the most capable systems. The China revenue line (about €9b of €40b+ annual sales) is meaningful, but it’s a slow burn subject to tech hurdles, yield, and supplier dependencies. Expect chatter, not an instant rewrite of the lithography landscape.
A countercase is that China finally achieves competitive yields and reliability in domestic immersion DUV, compressing ASML's pricing power and forcing a faster erosion of its service moat—if that happens, the near-term risk is speedier than the market assumes.
"China's targeted DUV substitution attacks ASML's last open high-volume China segment, accelerating margin compression beyond what export controls already baked in."
Claude's asymmetry claim misses how China's DUV push directly targets the exact mid-range nodes still open to ASML under current US/EU rules. The 20% China revenue (€9B) isn't legacy-only; it's the viable segment. If domestic tools hit 70% performance at 40% lower cost by 2028, SMIC/YMTC shift volumes faster than geopolitics alone would force, eroding ASML's pricing power before EUV moat fully compensates.
"The shift to domestic Chinese tools will trigger a total, permanent decoupling of the software and service ecosystem, not just a loss of hardware unit sales."
Claude and Grok focus on the hardware, but they ignore the service and software ecosystem—the 'hidden' revenue. If SMIC adopts domestic tools, they won't just buy hardware; they will build a captive software stack to avoid ASML's proprietary interfaces. This creates a permanent, non-recoverable loss of the service revenue that currently buffers ASML’s margins. The risk isn't just unit sales; it's the total decoupling of the Chinese semiconductor supply chain from ASML’s software-driven moat.
"Software decoupling is plausible but requires Chinese chipmakers to solve a second hard problem; cost arbitrage alone may be sufficient to shift volumes without full ecosystem independence."
Gemini's software-stack decoupling argument is the first concrete mechanism anyone's surfaced for *permanent* revenue loss, not just unit erosion. But it assumes Chinese firms can build proprietary stacks matching ASML's 30+ years of integration—a massive undertaking. The real test: do SMIC/YMTC actually *want* captive software, or do they tolerate ASML's interfaces if domestic hardware costs 40% less? If the latter, Gemini's 'non-recoverable loss' overstates the risk.
"Permanent loss from software decoupling is unlikely; ASML can monetize services and maintain a gradual erosion rather than a permanent collapse."
Gemini's software decoupling argument risks overstatement. Even if Chinese DUVs gain traction, a full captive software stack remains costly and error-prone; interoperability and yield data flows compel ongoing dependence on foreign calibration, metrology, and process-control tools. ASML can monetize through services, updates, and hybrid ecosystems, so the revenue erosion would likely be gradual, not permanent. If China pushes through, risk is a multi-year slowdown, not an instant collapse.
While the panel agrees that ASML's EUV dominance remains strong, there's a significant risk to its mid-range DUV business due to China's push for domestic lithography tools. The potential loss of service revenue and pricing power could erode ASML's margins in the coming years.
