From a review of SEC filings and individual Company information in MSN Money, I found 30 US Utility Companies with stock market caps sometime in 2018 of more than $10 Bil.
My Focus is on Pretax Income rather than on After-Tax Net Income because Corporate Income Taxes are simply a transfer of financial wealth between US Corporations and the US Federal, US State and Foreign Governments. It has nothing whatsoever to do with Company Operating Performance.
The chart below shows the Gold-Standard US GAAP Total Pretax Income (Loss) From Continuing Operations for the December 2018, the December 2017, the September 2018, the September 2017, the June 2018 and the June 2017 Quarters for each of these 30 Largest US Utility Cos.
