Does Berkshire Hathaway own part of Sumitomo?

Written by Admin | Last Updated: July 2026

Yes, Berkshire Hathaway effectively owns TransRe. The path to this ownership began when TransRe became a wholly owned subsidiary of Alleghany Corporation in 2012. Later, in October 2022, Berkshire Hathaway completed the acquisition of Alleghany Corporation in its entirety. Because Alleghany Corporation is now a wholly owned subsidiary of Berkshire Hathaway, all of Alleghany's underlying businesses, including TransRe, are now under the umbrella of Berkshire Hathaway. TransRe continues to operate as the brand name for Transatlantic Holdings Inc. and its various reinsurance subsidiaries. Consequently, through this layered acquisition process, TransRe is now one of the many insurance and reinsurance operations that fall under the ownership and control of the Berkshire Hathaway organization.
