A Tenet spokeswoman declined CNBC's request for comment. The Dallas Morning News reported last week that Glenview Capital Management, an activist investor that owns 17.8 percent of Tenet's stock, said in a regulatory filing it will consider options to enhance shareholder value, including "strategic alternatives" for Tenet's assets, divisions and the company as a whole. Tenet CEO Trevor Fetter discussed continuing to make divestitures but did not mention the possibility of a sale in an appearance at the Wells Fargo Health Care conference last week. Last month, Tenet said it would replace the longtime CEO and members of its board amid mounting pressure from Glenview. Fetter will step down by March 15, 2018, or when his successor is appointed, if that happens first. Glenview pulled two of its executives from the hospital company's board last month, citing irreconcilable differences.
