So Mr. SP is going to FURTHER increase his stake n Walgreens to almost 50%. Apparently he's going to be a major player in Walgreens when (or IF) the private equity buyout happens. And rather ironically if the buyout doesn't happen then by having almost half of the company he'll practically have controlling interest.
There was a recent article about him increasing his stake to 30% and now he's increasing it up to almost 50%? Something is obviously going on behind the scenes to keep SP in control of WBA.
