Not sure what you mean by "vertically integrated" they do not own cattle ranches or potato farms. They buy Heinz or Hunts catsup, etc. They do have a lot of proprietary recipes and process, but the ingredients are mostly sourced from other wholesale producers.

The cattle ranches and potato farms don't have their names or logos on the burgers or fries. McDonalds can swap them out at any time.

Soda, on the other hand, is Coke's product and brand completely.

Yes, this is hardly different from any other restaurant.
