Angela Ahrendts Looks to Revive Apple Stores’ Lagging Sales

Thirteen years after the first one opened, the Apple Store has entered an awkward adolescence. While Apple's storefronts remain the envy of the retail world, sales have flattened as the stores undergo a global growth spurt. Using one key measure in the retail industry, the stores generated $4,589 in sales per square foot in fiscal year 2014 — still better than any other brand, but down 23 percent from the $5,971 per square foot logged in 2012, according to research firm Customer Growth Partners.
