He takes over for David Kamenetzky, who is stepping down to start an investment business focused on the food and beverage sector.

Mars is the US' largest confectioner, including brands like M&Ms, Dove and Twix.

Mars said Kamenetzky's corporate strategy role will shift to CFO Claus Aagaard. CEO and office of the president Grant Reid praised Kamenetzky's ten years of service to the company's leadership team and board. "He has helped Mars engage with the external world more effectively, and pushed us to incorporate external insights into the business," said the CEO.

Pharoah joined Wrigley's corporate affairs unit in Munich in 2008 from Hill+Knowlton Strategies, before shifting to Chicago a year later.

Mars said this week it will buy out Berkshire Hathaway's 19% share of Wrigley in a de facto merger. Mars first took a stake in Wrigley in 2008.
