When you're a studio that's had a number of misfires like Legendary, even a franchise that turns in even a decent profit can be your "golden goose."
G14, K:SI, and even GVK made some money (though for GvK, seems like WB bought out Legendary's budget contributions and earned most, if not all, of the box office run profit). KOTM lost money, but I think GXK will continue the trend from GVK.
Edit: looks like some of us decided to respond at the same time with similar points 🤣
