Biogen Inc. reported solid second-quarter financial results, including revenues of $2.9 billion – a 12 percent increase compared to the same period in 2015. The bigger news – at least to those outside its Cambridge, Mass., headquarters – was the revelation by CEO George Scangos at the outset of the company's earnings call that he will leave the company "sometime within the next few months," following "an orderly transition," to return to the West Coast, spend more time with family and "take on one more set of activities."
