Warren Buffett’s Berkshire Hathaway holdings company is one of the largest companies in the world. In addition to holding shares in numerous different companies, Berkshire Hathaway actually owns all or a majority in more than 60 different companies spanning dozens of different industries. While many of its holdings are in the insurance business, there are many others which are just as large (or larger) but often overshadowed by Berkshire’s enormous presence in the insurance and reinsurance industry.
Warren Buffet often refers to these six behemoths as the Powerhouse Six, and while some of them have been a part of Berkshire for years, one was only added in 2016. And, of course, they span across several industries. Here they are, in no particular order:
1. Berkshire Hathaway Energy

It adopted the name Berkshire Hathaway Energy in 2014 and is made up of dozens of companies spanning eleven states in America as well as two other countries.
