Practically all of the major tourist attractions on Yas Island are owned by Miral (Sea World included), so they’re the Oriental Land Company equivalent. They’ll write a check to United Parks probably based on various percentages of each revenue source, like admissions, F&B, merch, and then probably some sort of base marketing/IP fee.
Financial statement implication is obviously higher revenue but that revenue will flow down to profit at a higher margin than the rest of the owned and operated locations.
