That is not how it typically works in China. The IPO money is used to finance corporate expansion.
China should respond by invalidating all of ASML's patents.
China should also forbid any Chinese companies from setting up their European HQ in the Netherlands. The Netherlands gets their income by operating as a giant tax heaven corporate scam.
Chinese government has honestly been way too lenient on these chip sanctions. Still refusing to even invalidate patents by AMAT and Lam in China.
It's clear that ASML hasn't done a good job of lobbying Dutch government here. They had threatened to leave Netherlands last year and all that got them is further restrictions. At this point, China has to put real pressure on ASML.
