ASML shares slide after report that China has begun making immersion DUV tools

Reuters reported that a state-owned Chinese company has started mass production of domestically made immersion DUV lithography tools. ASML shares fell more than 8% on Monday, July 27, with other equipment makers also lower. The report says output is small, with about five machines planned this year and about 20 in 2027, and the tools still trail ASML's products.

• Producer named as state-owned Shanghai Aishengna Electronic Technology Group
• Planned output about five DUV tools in 2026 and about 20 in 2027
• Reuters said the tool will not pose an immediate commercial threat to ASML
• Shares fell as much as 8.2% intraday on July 27 before trimming to about 6.7% (Motley Fool)
