第10名：医院运营商Community Health Systems

    交易代码: CYH

    年初至今股票表现: -53%

    市值: 16亿美元

    财富500强排名: 190

    医院运营商Community Health Systems（CHS）本打算今年以30亿美元敌意收购竞争对手Tenet Healthcare，结果碰了一鼻子的灰。2010年晚些时候，CHS发出了每股6美元的现金加股票收购要约，结果被Tenet董事会断然拒绝。

    接着，今年4月，就在Tenet指控CHS涉嫌超额收治患者、从联邦医疗保险计划（Medicare）套取资金后一周，CHS又发出了全现金收购要约。

    5月初，CHS又将要约价提高至每股7.25美元，但Tenet不为所动，几天后这宗收购无疾而终。

    今年前9个月，CHS的净营收增长9.8%达到了102亿美元，预计它还会继续四处收购。分析人士对此看法各持己见，但投资者则选择了回避该股，因为医保改革的不确定性对医院运营商冲击很大。他们担心根据医保改革计划，将来医院运营商可能要更多地分担医疗保险和医疗补助计划（Medicaid）的成本压力。

    Community Health Systems suffered a bloody nose this year with a botched $3 billion hostile takeover of Tenet Healthcare. The company made a $6 per share stock and cash offer late in 2010, but it was rebuffed by Tenet's directors.

    CHS then made the offer all-cash in April a week after Tenet sued it for allegedly over-admitting patients to draw more money from Medicare.

    The company raised its offer to $7.25 per share at the start of May, but Tenet held firm, and the deal died days later.

    CHS would continue to make acquisitions of hospitals here and there, with net revenue for the year climbing 9.8% to $10.2 billion after the third quarter. Analysts vary in their opinions, but investors have shunned the stock as uncertainty about the health care space hit hospital operators hard. It's feared that owners may have to shoulder more of the burden of Medicare and Medicaid costs with planned reform.
