Berkshire Hathaway (US0846707026) bundles a broad insurance core with industrial subsidiaries and a large listed equity portfolio in one NYSE-listed holding. The B shares track this structure and mirror the conglomerate’s long-term, fundamentals-driven approach.

How Buffett’s conglomerate is structured

Berkshire Hathaway is led by Warren Buffett and based in Omaha, Nebraska, with the holding company controlling more than 60 operating subsidiaries across insurance, energy, rail and manufacturing businesses. The group’s scale places it among the largest companies in the S&P 500 index.

Key operating pillars include Geico in auto insurance, National Indemnity in reinsurance, BNSF Railway in freight transport and Berkshire Hathaway Energy in regulated utilities, alongside manufacturing and retail units such as Precision Castparts and See’s Candies.

Insurance float as a funding advantage

The insurance operations generate premium float that Berkshire can invest until claims fall due, creating a structural funding source for its capital allocation. This float has historically financed large holdings in listed equities without requiring equivalent external debt.

Major insurance brands in the group include Geico in the US auto market and General Re in reinsurance, with activities spanning primary insurance, reinsurance and specialty lines across North America and selected international markets.

The equity portfolio as a second pillar

Berkshire’s listed equity portfolio includes large stakes in US blue chips such as Apple, major US banks and energy companies, managed centrally from the Omaha headquarters. The portfolio’s size makes Berkshire one of the largest single institutional investors in several S&P 500 constituents.

This equity book sits alongside wholly owned businesses, so the B shares give indirect exposure to both controlled subsidiaries and minority stakes in independent listed companies, bundled in one security on the NYSE.

What the company sells in practice

Operationally, Berkshire sells property and casualty insurance and reinsurance through brands such as Geico and General Re, freight rail transport via BNSF Railway, and electricity and gas distribution through Berkshire Hathaway Energy, complemented by a range of manufacturing and retail products.
