ASML's share price fell 11% after reports that Chinese state-backed Shanghai Aishengna Electronic Technology Group began producing domestic DUV lithography equipment, threatening ASML's 29% revenue exposure to China. Initial Chinese production targets five DUV machines in 2026 and ~20 in 2027, though questions remain about their technical performance and reliability versus ASML's established lead.

◆ ◆ The Wire takeaway
ASML just lost a quarter of its addressable market in one announcement. If you're selling precision optics, power management, or vacuum systems into semiconductor equipment, your current supplier relationship with ASML's competitors is about to face Chinese underpricing - and ASML will be forced to cut its own bill-of-materials costs to survive.
