Chinese DUV machines prompt ASML share decline

2 min read

Shares of ASML fell sharply after reports that a Chinese state-backed company has started manufacturing immersion deep ultraviolet (DUV) lithography machines, a market long dominated by the Dutch company. Analysts said the Chinese machines still lag ASML's technology, but China is expected to produce about five DUV machines this year and roughly 20 next year, versus ASML's roughly 130 expected shipments, making the move a potential long-term challenge. The reports triggered a near 6% sell-off and wiped billions off market value, even as demand for ASML equipment remains strong amid AI-driven chip investment and ASML expanding EUV capacity.
