WAG didn't buy Boots for the next quarter. The merger will make sense of the next 5-25 years.
Still, I would concede that it may be hard to generate growth in Europe over the next few years. However, the implementation of WAG's supply chain and management expertise may create a short term pop out of the Boots stores.
If this deal turns out to be acretive over 12-24 months, WAG stock will surge to $45.
