MINNEAPOLIS — Joseph J. Stone has been named enterprise leader for Cargill’s global agricultural supply chain, effective June 1. He will succeed GJ van den Akker, who has announced his intent to retire in 2020 after 30 years with Cargill.

Mr. Stone began his career in Cargill’s grain and oilseeds business in 1985, subsequently moving on to the company’s world trading unit in Geneva, Switzerland, in 2001. He most recently has been the enterprise leader for Cargill’s animal nutrition unit. Mr. Stone also is chair of Cargill’s Commodity Risk Committee, which provides strategic guidance and oversight for the company’s risk management activities globally.

He received a bachelor’s degree in agricultural economics from the University of Nebraska.

David Webster has been named to succeed Mr. Stone as enterprise leader of animal nutrition. Mr. Webster joined Cargill in 1992, working in production, sales, purchasing and finance before becoming a leader in Cargill’s premix business with the acquisition of Provimi. Most recently, he led Cargill’s global edible oils business.

“GJ and his leadership team have improved results in our ag supply chain while also driving important progress on critical safety, digitalization and sustainability goals,” said David W. MacLennan, chairman and chief executive officer. “Joe’s extensive risk management, trading, and grains and oilseeds experience will allow him to build on the momentum created by GJ and his team. And David is well positioned to execute on our animal nutrition growth strategy, leveraging his successful track record leading the premix and nutrition business and managing diverse global teams.”

Mr. van den Akker will continue to serve on Cargill’s executive team and lead key projects prior to his retirement, the company said.
