Grupo Bimbo, the world’s largest bread maker, has turned to Cleary Gottlieb Steen & Hamilton, Morgan, Lewis & Bockius, and White & Case for counsel on its $959 million purchase of Sara Lee Corporation’s North American bakery business.

The deal gives Mexico City-based Grupo Bimbo–owner of bread brands like Arnold, Entenmann’s, Freihofer’s, Stroehmann, and Thomas’ English Muffins–a huge boost in the U.S. bread market. Grupo Bimbo’s U.S. business, Horsham, Pa.-based Bimbo Bakeries USA, will merge with the newly acquired Sara Lee unit.
