Ralcorp Holdings has named Robert Vitale as CFO of Post Holdings, the US branded cereals business that will be spun off from the private-label food maker next year.

The split is scheduled to take place by early next year but Vitale will join Post on 1 November alongside its newly-appointed CEO of Post, William Stiritz, who is currently Ralcorp's chairman.

Vitale has been president and CEO of financial services group AHM Financial since 2006. His career also includes roles as chairman and majority shareholder of Canadian discount retailer The Bargain Shop and as partner at private-equity firm Westgate Group.

Ralcorp said Vitale had "significant investment experience" in the branded food, food ingredients and branded consumer products industries.

"Rob is a talented financial professional with the right skills and expertise to serve as CFO of Post Holdings," Stiritz said.
