BERKSHIRE HATHAWAY Class B
↗BRK.B
Berkshire Hathaway is a holding company with a wide array of subsidiaries engaged in diverse activities. The firm's core business segment is insurance, run primarily through Geico, Berkshire Hathaway Reinsurance Group, and Berkshire Hathaway Primary Group. Berkshire has used the excess cash thrown off from its operations to acquire Burlington Northern Santa Fe (railroad), Berkshire Hathaway Energy (utilities and energy distributors), and the companies that make up its manufacturing, service, and retailing operations (which include Precision Castparts, Lubrizol, Clayton Homes, Marmon, and IMC/ISCAR). The conglomerate is unique in that it is run on a completely decentralized basis. Berkshire is expected to generate close to $375 billion in revenue in 2025.
Market cap 1T
XPO, Inc.
↗XPO
Following the spinoff of its contract logistics division (GXO) in 2021 and freight brokerage operations (RXO) in 2022, XPO is moving closer to becoming a pure-play asset-based less-than-truckload carrier. We estimate LTL shipping makes up 60% of total revenue, with XPO's European truckload and LTL operations making up 40%. However, XPO's LTL segment EBITDA mix is much higher than 60%. We believe XPO intends to divest its European trucking division once it finds the right buyer.
