CHS, Inc., an Inver Grove Heights-based farmer-owned cooperative, said Monday that the voting members of New London, Wisconsin-based Larsen Cooperative Company have elected to merge with it.

Larsen will become the first Wisconsin-based co-op to join the CHS’ country operations business, through which CHS serves more than 50,000 producer-owners and other customers.

Larsen’s members approved the merger on Monday, and it will be completed in September, pending “appropriate due diligence by both organizations,” CHS said. Larsen will continue to operate under its own name, and its customers can expect “continuity of staffing at all its locations,” CHS said.

Agribusiness giant CHS is owned by farmers, ranchers, and cooperatives throughout the United States. It supplies energy, crop nutrients, grain marketing services, livestock feed, and business solutions such as insurance and financial management. It is also the largest national cooperative based on its revenue, which totaled $36.9 billion in 2011.

Larsen was founded in 1919 and provides agronomy, grain marketing, feed farms supply, and energy products, as well as home and garden, automotive, and hardware supplies. It offers services in 20 communities in northeastern Wisconsin. Its annual sales total $130 million, and it employs about 200 workers, according to a report by the Star Tribune.

“Our vision lines up well with CHS,” Larsen General Manager LeRoy Peterson said in a statement. “This is the right thing for us to do both for our patrons as well as our employees. It positions us to serve their needs well into the future.”
