The pressure is mounting for Health Management Associates Inc., which has adopted a poison pill in order to fend off the prospect of a takeover by hedge-fund operator Glenview Capital Management.
Shares of Health Management, an operator of acute-care facilities, jumped more than 5% in recent action to $11.62. On Friday, Health Management adopted the shareholder rights plan, also known as a poison pill, after the close in response to an increasing stake taken by Glenview, a New York-based fund.
