As I understand, Paramount does not receive any money from China box office - instead they took a flat $60 million fee to give full theatrical cut to the Chinese distributor. That $60million pays for almost half of the budget of Bumblebee alone.
So if take China out of the equation, it has grossed $263 million, while costing only $75 million budget. I can believe it has already made its money back and is profitable, yeah.
