If we take a look back at 2012—the year before the Kanye West announcement. It was a year that saw Adidas rake in an already pretty impressive $14.883 billion in sales with a %47 gross margin. By the end of 2015, Adidas had hauled in a whopping $2 billion more in sales ($16.915 billion) and a gross margin of 48% (+1%). And just in case you aren’t paying attention—that’s 2 billion dollars in added revenue.
How much of the boost was yeezy? I'm sure a huge chunk. This is what they both hoped would happen. All I'm saying is if/when Ye leaves, adidas will still be poppin.
