Diniz's father, Valentim Diniz, founded the company Pão de Açúcar in September 1948. Abilio Diniz began to work for his father at Doceria Pão de Açúcar at the age of 12. In April 1959, the same year he graduated from FGV in Business Administration, he partnered with his father to create the first Pão de Açúcar supermarket store, located on Brigadeiro Luiz Antônio Avenue, in São Paulo. In 1960, after the first store was established, Diniz traveled for four months throughout Europe and the United States to observe the operation of the retail sector abroad. The second Pão de Açúcar location on Maria Antonia Street, downtown São Paulo, was established in 1963. One year later, Pão de Açúcar acquired Quiko and Tip Top supermarkets. During the 60's and 70's, Grupo Pão de Açúcar was the first supermarket chain to set up a store in a shopping mall (Iguatemi, in São Paulo), to have a 24-hour pharmacy, and to set up a data processing center. Diniz studied the operations of Paris-based Carrefour in 1967 after
Luiz Carlos Bresser-Pereira, who worked at Pão de Açúcar, introduced him to Carrefour cofounder Marcel Fournier. Diniz was a co-founder of the Brazilian Association of Supermarkets in 1968. Inspired by the Carrefour hypermarket model, Diniz founded Jumbo, the first hypermarket in Brazil, in Santo André in 1971. In 1976 he acquired Eletroradiobraz, the second largest chain of supermarkets and hypermarkets in Brazil at the time. The company consisted of eight supermarkets, 26 hypermarkets, 16 stores and a warehouse. In 1979, Diniz moved away from Pão de Açúcar and became part of the National Monetary Council at the urging of the Minister of Planning, Mario Henrique Simonsen. There, he coordinated the production of economic bulletins. In 2005, Diniz sold a large stake to the French company
Casino Group for an estimated $860 million and stepped down as CEO, but remained as chairman. In 2009, in one of the most expensive transactions of the Brazilian business history, Grupo Pão de Açúcar bought
Casas Bahia from
Samuel Klein, giving Abilio control of Pão de Açúcar, Casas Bahia, Ponto Frio and
Extra Hipermercados. In 2012, Casino Group took control of Grupo Pão de Açúcar and Diniz no longer had operational functions within the group but remained as chairman. In 2003, Diniz became a member of the Economic and Social Development Council, a group of civil representatives which advise the President of the Republic of Brazil. In 2006, Diniz founded Península Participações, an investment company created to manage the assets of the Diniz family through private and liquid investments. He later became the chairman of the company's board of directors. In April 2013, Diniz was elected as chairman of BRF. He helped lead the company through a broad restructuring. The company's profit went from R$700 million in 2012 to R$2.2 billion in 2014. The company's market value went from R$37 billion to R$55 billion. In September 2013, Diniz signed an agreement with his partner Jean-Charles Naouri to leave Grupo Pão de Açúcar. His shares were converted into voting privileges and he resigned from his position as chairman and the position was filled by Naouri. Diniz changed his focus to Península Participações, which managed more than 10 billion reais in assets by 2014. In April 2015, Diniz announced he was wrapping up talks to raise his 5.07 percent stake in
Carrefour and that he had shareholder support to take a seat on the board of the supermarket. Through Península Participações, Diniz acquired 10% of the shares of Carrefour Brazil. Península Participações continued to acquire shares of
Carrefour, and by March 2016, it was the third largest global shareholder of the Carrefour chain. In 2017, it had 11.46% of the shares of Carrefour Brasil and 7.7% of Carrefour. Diniz serves on the group's board of directors. ==Writing==
