Late last month, the Dutch government restricted sales of ASML's advanced immersion lithography tools to China. But it looks like ASML is facing further high-tech export constraints from the Dutch and United States governments. The new rules may restrict ASML's ability to service existing production tools in China, according to a Bloomberg report that cites sources familiar with the matter.
The upcoming Dutch export control rules will require ASML to obtain government authorization to service, repair, and supply parts for its dry and immersion lithography tools that are already used by its customers in China. Services, repairs, and spare parts represent an important source of ASML's income. The company has previously earned some $5.743 billion — 27% of its revenue — servicing its tools in the field.
