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
Lowe's Companies Inc.
↗LOW
Lowe's is the second-largest home improvement retailer globally, with more than 1,750 stores in the US, after the 2023 divestiture of its Canadian locations. The firm's stores offer products and services for home decorating, maintenance, repair, and remodeling, with maintenance and repair accounting for two-thirds of products sold. Lowe's primarily targets retail do-it-yourself (around 70% of sales) and do-it-for-me customers, but has expanded its professional business clients to 30% from less than 20% in the past seven years (set to expand further with the acquisition of FBM). We estimate Lowe's captures a high-single-digit share of the domestic home improvement market, based on US Census data and management's market size estimates.
