Northern Growers, LLC is a South Dakota limited liability company that owns and manages a 77.16% interest in POET Biorefining - Big Stone. Northern Growers' members are primarily local agricultural producers and they supply a significant portion of the plant's corn requirements.

Northern Growers was originally formed as a South Dakota cooperative and on March 27, 2003, the members of Northern Growers approved a reorganization into a South Dakota limited liability company effective April 1, 2003.
