Dreyer's Grand Ice Cream Holdings is to buy compatriot ice-cream snack maker Silhouette Brands for US$65.2m.

Ten-year-old Silhouette, based in New York, makes 'healthier' ice cream snacks under the Skinny Cow and Skinny Carb brands. Dreyer's already distributes the brands for Silhouette, but said it expects "significant administrative, selling and management synergies (and) reduced costs" following the merger.

"Skinny Cow has been the fastest growing partner brand in Dreyer's portfolio of distributed brands in recent years," Alberto Romaneschi, Dreyer's chief financial officer, commented in a company statement.

The leading US ice cream maker, Dreyer's is a majority-owned subsidiary of Swiss food giant Nestlé.
