ASML Drops 6% on Reports of Chinese DUV Breakthrough
Question
ASML Drops 6% on Reports of Chinese DUV Breakthrough
Direct answer
While ASML's high-end EUV business remains a monopoly, the DUV segment is a significant revenue driver. Reports of Chinese domestic DUV production, even at low volumes, signal a long-term threat to ASML's service and equipment revenue in the region. Analysts suggest the immediate threat is overstated, but the sentiment shift reflects growing geopolitical risks for Western semi-cap equipment providers.
