Current CFO Paul Herendeen will take on the role of advisor to the chairman and chief executive officer, the company said.

Eldessouky's appointment comes amid calls from activist investor Glenview Capital Management for Bausch to spin-off Bausch + Lomb by year-end. The company in August said it would offload the unit into a separate publicly listed firm.

Bausch last month agreed to add directors from Icahn Group to its board, weeks after activist investor Carl Icahn disclosed a nearly 8% stake.

Eldessouky joined Bausch Health, previously known as Valeant Pharmaceuticals, in 2016 as senior vice president and corporate controller.
