How will stocks like AMD, NVDA be affected if Russia invades Ukraine?

I know no one can predict this for sure but since 90% of semiconductor-grade neon comes from Ukraine, if Russia goes to war with them how will it impact stocks from companies that rely on it? Primarily AMD and Nvidia, but also companies like Microsoft, Tesla, Apple etc. which also rely on semiconductors for manufacturing, would their stock prices go down? I would imagine, especially since the entire stock market would take a hit, but particularly those that rely on imports from those countries. Of course I'm praying that no war breaks out but it does make me wonder what will happen to these companies that had been thriving up until recently.
