a stock split is an expense without a purpose. let it run. There was a time when it was difficult to buy stock in lots under 100 shares, so keeping the share price low made a company's stock more affordable. Today you can order 10 shares and get a rapid execution.
The company plans on letting this stock go above 100, the powers that are in charge do not like the idea of a split. Allliance Boots is working and will be wholly purchased in 2015. 50/50 that Wag will move headquarters over to Europe and add billions to the bottom line, thanks to US being greedy in going after tax genie, they will kill the golden goose.
I think there will be a dividend increase, but I'm not sure it will be generous. Walgreens, while determined to maintain shareholder interest, will probably allocate as much cash as possible to the Alliance Boots acquisition.
