Amazon recently sent a letter to a number vendors on its first-party (1P) platform informing them they would move to third-party (3P). What’s the change and why?  Under 1P, Amazon takes the inventory and price risk. Under 3P, the vendor (brand owner) takes these risks. Australian retail profit margins are generally higher than five years ago with gross margins better than feared. In our view, a key reason is that online retailers are less aggressive on price. Amazon’s shift is a good example of the shift in mindset. We expect retailers to sustain higher gross margins. The problem is their sales growth may remain underwhelming relative to operating cost growth.
