How this list is ranked
Companies are ranked by annual revenue (USD) as recorded on each company's profile in the Factur directory, highest first; companies with the same revenue are ordered by employee count. Only companies with a positive revenue figure on file are ranked, so a large private company with no reported revenue can be missing. The list covers companies whose record places them in Minnesota and whose NAICS codes include 332322, 332312 or 332119. Figures are a snapshot of the directory, refreshed when the rankings are regenerated; open a profile for its current data.
