It’s the max salary rate for a given level according to company policies. Once you hit this, no matter how well you do they’ll try to tell you you can’t get a raise unless you get a promotion. Of course, this matters little since they will be shoveling RSUs at you if they want to keep you.
Oh yeah, and mirroring other comments, this is the max base for the highest level in this case, so it is the max max. And also it’s never really true that they can’t exceed it. Everything is negotiable if you’re hot enough shit.
