ASML dismisses claims of Chinese tool stockpiling, says ready for rare earth curbs

ASML has downplayed concerns that its expected decline in China sales next year is linked to Chinese chipmakers stockpiling its lithography machines, saying the slowdown reflects market dynamics rather than preemptive buying.

“The reason I rule out previous stockpiling is because systems that we ship are actually in a chips factory,” said Chief Financial Officer Roger Dassen during a press briefing on Wednesday. His comments followed ASML’s third-quarter earnings report, which warned of a significant fall in Chinese demand in 2025.

Chinese customers accounted for 42% of ASML’s machine sales in the latest quarter, making China its largest single market. However, U.S. lawmakers have urged tighter export restrictions on ASML, alleging that Chinese firms are purchasing chipmaking tools beyond domestic needs to hedge against future sanctions.

ASML, the world’s top semiconductor equipment maker, said it remains confident in the resilience of its business outside China, despite ongoing geopolitical uncertainty.

Dassen also addressed concerns about China’s rare earth export restrictions, emphasizing that ASML is well prepared in the short term. “We have inventory, we have alternatives. But of course, there is an impact we are navigating,” he said.

China produces over 90% of the world’s processed rare earths and magnets, which are essential components in ASML’s chipmaking tools. Dassen cautioned that longer-term disruptions could be more serious if global trade tensions deepen. “It’s important the world continues to trade so we don’t face lasting limitations,” he said.
