Wyo-Ben, Inc.

Based in Billings, Montana, with over 70 years of operations, Wyo-Ben is a 5th generation family business with extensive experience extracting and processing sodium bentonite. With the acquisition of M-I, the Company operates four production facilities across the Wyoming Big Horn Basin. Wyo-Ben supplies bentonite as the primary ingredient used in cat litter (to third parties and its own operations), as well as mission-critical bentonite products for industrial applications, including oil well drilling, horizontal directional drilling, water well drilling, iron ore pelletizing, water treatment, and more. In 2021, the Company opened its cat litter packaging facility in Billings, MT to provide private-label cat litter for major big-box retail customers, utilizing its own sodium bentonite as the core ingredient. Bison Capital’s growth investment will be used to expand the Company’s cat litter packaging operation through increased automation and improved packaging capacity.
