Conglomerates & Holding Companies covers diversified industrial conglomerates and holding companies. MoatScope covers 12 companies here. Two have a wide moat, three a narrow moat and seven none.

How the industry makes money

These companies own many businesses and allocate capital among them. The strongest acquire or build durable businesses and let them compound; the weaker ones trade at a discount because the whole is worth less than its parts.

Where the moats are

  • Berkshire Hathaway: a vast portfolio of wholly owned businesses, led by GEICO and other insurers, whose cost advantages and scale are hard to match.
  • Honeywell: aerospace, automation and building technologies built into customers' systems.

The narrow-moat group is 3M, Loews and Brookfield Business. Icahn Enterprises, Seaboard and Cannae carry no moat.

What wears moats down

Poor capital allocation, holding-company costs and businesses that no longer fit together can erode value, which is why many conglomerates break themselves up.

What to watch

  • Breakups, spin-offs and acquisitions.
  • Capital allocation and buybacks.
  • Performance of each business unit.

Market share

Businesses ranked by revenue, with each one's share of the market's total: companies filed under this industry, the segments of companies filed elsewhere that compete in it, and the largest companies MoatScope doesn't cover, such as private companies and companies listed outside the US. Each market's total comes from a cited source and covers the geography its businesses compete in (a national market counts only US revenue). A company that runs several businesses is split by the segments it reports.

12 businesses MoatScope covers, ranked by revenue. These companies compete in different national markets, so there's no single market to take a share of. Conglomerates run unrelated businesses, so there's no single market to take a share of.

Market share is a company's revenue in its main market as a share of that market's total: every company in it, including private companies and companies listed outside the US (sources under each market above). Revenue is for the fiscal year closest to 2025, and a market that is national (such as US banking) counts only US revenue. Companies that run several businesses are split by the segments they report, and each segment counts in its own market. A dash means the market has no reliable total yet, or no revenue was reported for that year.
