Deutsche Bank analyst Chris Rigg believes Tenet Healthcare's (THC) leverage makes for an "extremely wide" range of potential buyout prices. After the Wall Street Journal reported that the company is exploring strategic options including a possible sale, Rigg pegs $21-$41 per share as the potential buyout range. Also difficult is determining who would actually be interested and capable of buying Tenet, Rigg tells investors in a research note. HCA Holdings (HCA) has the financial wherewithal to do a deal, but the companies have significant overlap which could bring antitrust issues, the analyst contends. He sees private equity or an existing private equity-backed hospital chain as making more sense. Rigg has a Buy rating on Tenet with a $24 price target.
