The panic that gripped ASML’s share price lasted barely a week. By Thursday’s close, Europe’s most valuable technology company had clawed back 6.71 percent to finish at €1,444.00, as investors concluded that the threat from a newly confirmed Chinese competitor was more distant than the initial sell-off suggested.
The turbulence began when Reuters confirmed that Shanghai Aishengna Electronic Technology Group — a state-backed entity registered in August 2023 with roughly $1 billion in capital — stands behind China’s first domestically produced immersion DUV lithography scanner. The machine, designated SSA800, is slated for small-batch production beginning this year, with approximately five units planned for 2026 and around twenty for 2027. Initial customers include SMIC, Hua Hong, and CXMT, with SMIC already testing a so-called Yuliangsheng tool since September 2025.
Yet the technology gap between Veldhoven and Shanghai remains cavernous. According to an Asia Times analysis, the SSA800 is roughly comparable to ASML’s NXT:1950i model from 2008 — placing China about four generations behind the industry leader. While roughly 70 percent of the SSA800’s components now come from Chinese manufacturing, the country still depends on foreign suppliers for critical elements. Precision optics come almost exclusively from Carl Zeiss SMT, Japanese firms including JSR, Tokyo Ohka Kogyo, Shin-Etsu, and Fujifilm dominate the ArF photoresist market with Chinese producers holding under one percent share, and Cymer, Gigaphoton, and Coherent control more than 80 percent of excimer laser supply. Estimates suggest a Chinese scanner capable of 7-nanometer production may not be realistic until 2038.
That assessment helped reverse the selling pressure. JP Morgan analysts characterized the prior week’s sell-off as disproportionate, a view that gained traction as investors weighed the production numbers: ASML shipped 279 DUV machines last year alone and plans to expand immersion DUV capacity by 30 percent through 2027. Against that backdrop, roughly five Chinese systems in 2026 and twenty in 2027 look modest.
The recovery, however, only partially repairs the damage. ASML shares remain 6.69 percent lower over a seven-day stretch and trade about 6 percent below their 50-day moving average. The bounce reads more as stabilization than reversal, though longer-term holders can take comfort in the stock’s still-substantial gains over the past year, supported by unabated demand for lithography equipment in AI-driven chip manufacturing.
The sell-off that preceded Thursday’s rebound was severe: ASML lost roughly 11 percent in a matter of days, erasing approximately €60 billion in market capitalization. The trigger was purely the confirmation of Aishengna’s DUV program — a development that, on closer inspection, appears less threatening than the initial market reaction implied.
Should investors sell immediately? Or is it worth buying Asml?
Washington has added a second layer of tension. US Commerce Secretary Howard Lutnick raised concerns that EUV components may have reached China improperly, a charge ASML CEO Christophe Fouquet rejected, pointing to an internal “firewall” designed to prevent reverse engineering and emphasizing the substantial technological distance Chinese manufacturers still must close. Meanwhile, the US government has invested in xLight, a startup positioned to challenge ASML’s EUV monopoly, and Congress is weighing the MATCH Act, legislation that could further restrict DUV deliveries and service to China.
ASML’s EUV dominance remains its trump card. The company is the world’s sole producer of EUV lithography systems, with low-NA machines priced around $200 million each and high-NA versions exceeding $400 million. TSMC plans to stick with the cheaper low-NA technology for now, Intel has adopted high-NA for its newest fabrication processes, and Samsung is expected to follow in coming years. Market researchers project double-digit growth for the EUV segment, and ASML targets annual revenue between €44 billion and €60 billion by 2030.
China’s importance to ASML’s business is also diminishing independent of the competitive threat. Last year, China accounted for 29 percent of company revenue; by the second quarter, that figure had dropped to 14 percent, down from 33 percent in the year-earlier period. ASML itself projects China will contribute roughly 20 percent of group sales this year.
Wall Street has responded to the recent volatility with measured confidence. US analysts have raised their average price target to approximately $2,177, with most maintaining buy ratings. They flag lingering risks: potential new US export restrictions, the negative free cash flow of minus $3.08 billion in the first quarter, and the long-term question of how quickly Chinese manufacturers can close the technological gap.
The broader semiconductor sector also brightened on Thursday, with Lam Research and KLA posting double-digit gains after the industry had shed roughly $1 trillion in market value two days earlier. For ASML investors, the calculus remains straightforward: the Chinese rival is real but distant, the political pressure from Washington is persistent but manageable, and the order book for EUV systems — the machines no one else can build — remains the foundation on which the company’s valuation rests.
