The Wall Street Journal reports that a potential take-private deal between Walgreens and private equity firm Sycamore Partners, which was first reported in early December, is no longer on the table. Shares of the retail pharmacy dropped on the news, further escalating the stock's see-sawing as Walgreens investors react to a DoJ lawsuit and better-than-expected quarterly earnings. WBA shares have lost 52% in the past 12 months.
