In September 2010, 3G launched a $4 billion bid, at a 45% premium over market, for all the stock of Burger King. "3G was advised in the BK offer by Lazard, J P Morgan Chase, Barclays Capital and the law firm Kirkland & Ellis. 3G already has some experience in burgers and fries, having previously invested in Wendy’s." Together with Berkshire Hathaway, 3G Capital acquired the H. J. Heinz Company for $28 billion in 2013. Its new CEO Bernardo Hees is a former manager of Burger King. The same group announced the merger of Kraft Foods with Heinz in March 2015.
