Wyo-Ben

David Brown serves as President and CEO, leading the company on behalf of the Brown family. The family has held operational control since the company's founding in 1951 near Greybull, Wyoming. No outside private equity or institutional ownership stakes have been publicly disclosed, and the firm remains a privately held industrial operator.

Wyo-Ben produces processed bentonite clay products for drilling fluids, foundry sand binders, environmental sealing applications, water clarification, and consumer products including cat litter. Its output serves the oil and gas, construction, metalcasting, and environmental remediation industries. The company controls its own mining reserves and operates processing plants to manufacture finished products.

The company controls significant reserves of high-quality sodium bentonite in Wyoming's Bighorn Basin, a region that supplies the large majority of global sodium bentonite. Bentonite is a bulk commodity where transportation cost dominates delivered price — Wyo-Ben's mine-mouth processing plants minimize those costs while its multi-generational, private ownership allows it to operate through commodity downturns without the quarterly earnings pressure of publicly traded competitors.

Wyo-Ben's capital deployment is concentrated within the industrial bentonite value chain: mine development in Wyoming, plant capacity expansions at its Montana and Wyoming sites, logistics infrastructure like the 2024 North Dakota transload terminal, and selective acquisitions of related processing assets or distribution networks. It does not operate as a diversified holding company or financial investor.

The firm operates as a privately held Delaware corporation (Wyo-Ben, Inc.) with its headquarters in Billings, Montana. Governance is family-led without public board composition disclosure. Operational decisions are made by the President/CEO and a management team focused on mining, processing, and sales, without evidence of an external investment committee or formal family-office allocation structure.

The company operates bentonite mines and processing plants near Greybull, Thermopolis, and Lovell, Wyoming, with additional processing and blending operations in Billings, Montana. A 2024 North Dakota transload terminal extended its distribution reach into the Williston Basin. Additional facilities have been operated historically in Canada and the Appalachian region through acquisitions.

Primary customers include oilfield service companies using bentonite for drilling mud, construction firms using drilling fluids for horizontal directional drilling, foundries consuming bentonite as a sand-binding agent, and environmental engineering firms specifying bentonite for landfill liners, pond sealants, and slurry walls. Consumer products, including cat litter, represent a smaller but steady downstream channel.
