Taking $0 is unusual but not unheard of (Musk I think does this too) and it’s very common for CEO’s to make $1mill (or even less) and have like…80%+ of their compensation tied to performance metrics/stock options. There are a lot of caveats to saying “he takes no salary.”
It sounds nice on paper but he isn’t really doing something revolutionary here. He also has rather ambitious numbers to hit if what I’m reading is accurate, so it makes sense he’s taking massive swings like this. We’ll see if it happens, let alone pays off.
