From a review of Company SEC filings and the Google Finance website, I found 5 Madison, Wisconsin Companies with stock market caps above $1 mil recently. Two of them are Utility Companies and three of them are Non-Utility Companies.
The table below shows the Gold-Standard US GAAP Pretax Income (Loss) From Continuing Operations for the second and first quarters of both 2020 and 2019 for each of these 5 superb Madison, Wisconsin Companies.
