Syngenta AG has named Chief Financial Officer John Ramsay as provisional CEO to replace Mike Mack, who unexpectedly quit amid mounting shareholder criticism at the world’s largest agrochemical maker for his refusal to engage with Monsanto Co. over its $47 billion takeover approach.

Ramsay will replace Mack on an interim basis, the Basel-based company said in a statement on Wednesday. A U.K. national, Ramsay has spent more than three decades in the chemicals industry, first joining Imperial Chemical Industries in 1984 before overseeing finances at Zeneca Agrochemicals, which later became the foundation of Syngenta following a merger. Syngenta shares gained as much as 5.1 percent.
