CVS Health has added four new board members, including the chief executive of a hedge fund that has been critical of the struggling healthcare giant. The company said Monday that it expanded its board to 16 members following “productive discussions” with shareholder Glenview Capital Management.

CVS Health Corp. named Glenview Capital Management founder Larry Robbins to its board as part of an agreement with the activist firm that’s been pressuring the company for change.

CVS Health said four new members will be added to its board from the hedge fund Glenview Capital, which had been pushing for changes at the diversified healthcare giant.
