MINNEAPOLIS — Actus Nutrition, a portfolio company of Butterfly Equity, has acquired a Sparta, Wis.-based whey protein processing facility from Foremost Farms USA, a dairy cooperative and food manufacturer. Financial terms of the acquisition were not disclosed.

“We’ll be able to hit the ground running because we can plug the Sparta facility into our existing manufacturing network without a lot of changes,” said David Lenzmeier, chief executive officer of Actus Nutrition. “The facility will provide added capacity that will help us better meet the insatiable global demand for whey protein, while further positioning Actus to meet the needs of our existing customers.”

Actus, founded as Midwest Dried Milk Co. in 1948 in Dundee, Ill., said it will invest “significant capital” into the 99,000-suqare-foot facility to increase capacity and expand capabilities.

The acquisition grows Actus Nutrition’s Wisconsin manufacturing facility network from six to seven. Actus also operates manufacturing facilities in Minnesota, Nebraska, California, Idaho and Illinois.

Actus Nutrition’s portfolio of ingredients includes whey proteins, milk proteins, casein and caseinate, dairy and plant fats and carbohydrates.
