ASML (ASML) Stock Plunges 7% as China Announces Domestic DUV Lithography Production

Key Takeaways

• A state-backed Chinese enterprise in Shanghai has initiated mass production of domestically developed immersion DUV lithography equipment for the first time.
• ASML shares plummeted more than 7% following the announcement, wiping out a 2% pre-market rally.
• American semiconductor equipment manufacturers Applied Materials (AMAT), Lam Research (LRCX), and KLA Corp (KLAC) experienced declines ranging from 4% to 7%.
• The Chinese DUV technology remains in its infancy — production targets are set at just 5 machines in 2024, expanding to 20 by 2027.
• This advancement puts at risk ASML’s remaining significant revenue stream in China, where DUV equipment sales compensated for prohibited EUV transactions.

Shares of the Dutch semiconductor equipment manufacturer took a significant hit Monday following reports that a Shanghai-based, government-supported company has commenced mass production of domestically produced immersion DUV lithography systems.

ASML’s stock price collapsed by over 7% during Monday’s trading session after The Information published the breaking news. The dramatic reversal was particularly striking given that shares had climbed more than 2% in pre-market trading, buoyed by reduced Middle East tensions and reports of Nvidia’s potential involvement in a massive $250 billion OpenAI data center project. That early enthusiasm quickly disappeared.

ASML Holding N.V., ASML

The company’s revenue dependence on China has remained a persistent worry for market participants. ASML’s second quarter results revealed that China represented 14% of net systems revenue, marking a decline from the 19% recorded in the first quarter. Chief Financial Officer R.J.M. Dassen had previously projected China would contribute approximately 20% of annual net sales. That guidance now faces significant uncertainty.

Since American and Dutch export restrictions already prevented ASML from shipping its cutting-edge EUV systems to Chinese customers, semiconductor manufacturers in China responded by accumulating ASML’s previous-generation DUV equipment. These DUV transactions evolved into an essential revenue source. Should Chinese domestic producers successfully bridge this technology gap, ASML’s existing market position in China faces direct jeopardy.

The unidentified Shanghai company allegedly built its engineering workforce by recruiting specialists from various Chinese enterprises, including the state-supported startup Shanghai Yuliangsheng Technology.

American Semiconductor Equipment Manufacturers Feel the Pain

The damage extended beyond ASML. Applied Materials declined approximately 5%, while Lam Research tumbled nearly 7%, and KLA Corp retreated close to 5%. These firms provide machinery for complementary semiconductor manufacturing processes — including material deposition, pattern etching, and quality inspection.

The market’s reasoning is straightforward: lithography technology has historically represented the most challenging obstacle in chip production. Should China successfully overcome this barrier, market participants worry the remaining supply chain elements could follow suit.

This market downturn coincides with congressional momentum behind the MATCH Act, bipartisan legislation intended to prevent China from acquiring or maintaining DUV equipment. However, if Chinese manufacturers can now produce these machines domestically, such restrictions may prove less effective than originally anticipated.

Chinese Technological Advancement Is Genuine — Yet Remains Nascent

Context matters significantly here. The Chinese-manufactured DUV systems remain in preliminary development stages. The Shanghai company aims to manufacture merely five machines this year, targeting an increase to 20 units by 2026. This output pales in comparison to ASML’s production capacity.

China’s EUV technology development lags even further behind — these advanced machines remain in experimental phases and likely face a multi-year timeline before reaching commercial viability.

Nevertheless, the trajectory is unmistakable. Beijing designated lithography as a strategic national objective in 2002, and following Washington’s tightened export restrictions in 2022, China transitioned from government-led research initiatives to an accelerated public-private partnership approach.

ASML’s second quarter earnings report, published before Monday’s developments, had already highlighted weakening Chinese demand. The company now confronts the prospect of further deterioration in its DUV revenue from the region as Chinese domestic alternatives expand production capabilities.
