Kainos, a Dallas-based private equity firm focused on food and consumer goods, said Slim-Fast will slide into its health and wellness group that includes NutraLife (vitamins), Healthy Delights (supplements), Milk Specialties Global (whey protein) and InterHealth Nutraceuticals (ingredients for nutraceuticals).
The purchase price was not disclosed. Unilever bought Slim-Fast in 2000 for $2.3B.
Kekst managing directors Mark Semer and Daniel Yunger rep Kainos.
Unilever said the sale is the "last step" in a retooling of its offerings in North America. The company in May unloaded its Ragu and Bertolli sauce lines to Japan's Mizkan Group for $2.15B.
Healthy Delights CEO Chris Tisi adds CEO duties for Slim-Fast in the deal.
Unliver noted that Slim-Fast's shakes, powders, bars and other supplements are sold in North America, the UK and Ireland. Anita Larsen handles Unilever's North American communications.
