And then there's the fact of Mylan's move to the Netherlands, which it made in 2015 to reduce its tax bill. The company found it was able to employ a European-style poison pill called "stitching" when it was approached by Teva Pharmaceuticals with a hostile bid for $82 per share that year. "Stitching" allows companies to form foundations that buy enough shares of stock to exercise voting options, and in turn, voting against a hostile takeover. This also allows the company to keep board members in place despite dubious actions. Two activist firms are currently invested in Mylan—Greenlight Capital Inc., which has a 1.62% stake in the company, and Paulson & Co., which has taken a 3.85% stake in Mylan. But the effectiveness of either of these firms will likely be minimal, given Mylan's ability to employ "stitching" to thwart outside pressure for change. Then there are Bresch's dubious political ties. Bresch's father is Joe Manchin, a West Virginia Democratic senator.
