Following Thursday's Supreme Court decision rejecting a challenge to the Affordable Care Act, hospital stocks jumped. The jump is likely an indication of a possible M&A in the space and surrounding areas. The 6-3 ruling in King v. Burwell, with Chief Justice John Roberts Jr. writing the opinion for the majority, means hospitals can confidently broaden their geographic reach and widen their care offerings by acquiring physician groups, imaging businesses and urgent care facilities. And they can buy other hospitals. One industry banker noted that people in the hospital industry had been anxiously awaiting a decision on the ACA-- as a result many buyers and sellers have waited on the sidelines. The ruling helps to remove an unknown for both parties. Large players in the hospital area include Tenet Healthcare Corp, HCA Holdings Inc., Community Health Systems and Universal Health Services Inc which also operates in the behavioral health sector. Pure play behavioral health provider Acadia Healthcare Company Inc. could also be looking to buy.
