Selected from a shortlist of ten companies including Apple and Tesco, the winners of the Foundation awards were announced in London.
"The bar has now been raised for businesses all over the world to follow suit," said Monique Villa, chief executive of the Thomson Reuters Foundation.
"The Stop Slavery Award wants to start a virtuous circle by proving that corporations play a key role in the fight against slavery," she added.
The Thomson Reuters Foundation is a London-based charity that is independent of Thomson Reuters and operates independently of Reuters News.
The Foundation stands for free independent journalism, human rights, women's empowerment, and the rule of law.
