This doesn’t come as a big surprise for me, as we all know how much money was put into the Flipkart acquisition and how much money, in general, is being put into Walmarts shift to e-commerce. In my opinion, it is smart not to burden the company with exaggerated earning goals as we wait for these investments to start paying off.
