[2][3] The subsidiary, headquartered in Horsham, Pennsylvania, a suburb of Philadelphia,[4] owns many fresh bread and sweet baked goods brands in the United States, including Arnold, Levy's, Ball Park, Columbo, Francisco, Oroweat, Entenmann's, Sara Lee, and Thomas'.

In 2002, BBU acquired the Western U.S. baking business of George Weston Ltd., adding such iconic premium brands as Oroweat, Entenmann's, Thomas’, and Boboli.

In 2008, Grupo Bimbo purchased the remaining U.S. fresh baked goods business of George Weston Ltd., adding brands such as Arnold, Brownberry, Freihofer's, and Stroehmann.

In 2011, BBU completed its largest acquisition to date: Sara Lee's North American fresh bakery business.

Kosher breads are required to be non-dairy unless explicitly labelled because Jewish dietary restrictions prohibit consuming dairy and meat at the same meal.

[10] The company said they wanted the option to produce bread on factory lines that might include dairy products, which they are not able to do if they remain kosher certified.

[16] On November 9, 2010, Grupo Bimbo announced that it had agreed to acquire the North American fresh bakery business of the Sara Lee Corporation.

The transaction, which was subject to regulatory review, would combine the largest and third-largest baking companies in the United States, as measured by annual sales.

In November 2011, Sara Lee Corporation completed the sale of its North American fresh bakery business to Grupo Bimbo for $709 million.
