A great thing about GloblaFoundries is that its foundries and manufacturing centers are located in the US, Germany, and Singapore.

Many foundries are located in Taiwan. This is problematic as tensions between Taiwan and China grow. The closest factory that GlobalFoundries has to Taiwan is Singapore, but at least most of its factories are in the West.

While investors in the semiconductor industry like $TSM because of its scale and for having the largest market share, the majority of its foundries are in Taiwan. A Chinese attack on Taiwan would destroy most of TSMC's factories.

$INTC and other chipmakers also have foundries in Taiwan, but they're starting to build foundries in other places like the US, Israel, Ireland, Germany, etc.

If an attack on Taiwan happens, at least GlobalFoundries can still operate like usual.
