Sigma Readies IPO Papers

Mexico’s Sigma Aliementos has made the initial filing for its IPO process, according to regulatory documents. The Grupo Alfa subsidiary has hired Citi, Goldman Sachs, Bank of America Merrill Lynch and Banorte-Ixe. The size and timing remain unclear, though a filing now leaves open the possibility to get a deal done before the end of the year. The filing follows last week’s unveiling of a EUR675m ($908m) bid for European meat company Campofrio Food Group.
