Description

Berkshire Hathaway Inc. () is an American multinational conglomerate holding company headquartered in Omaha, Nebraska. Originally a textile manufacturer, the company transitioned into a conglomerate starting in 1965 under the management of chairman and CEO Warren Buffett (from 1970 to 2025) and vice chairman Charlie Munger (from 1978 to 2023). Greg Abel succeeded Buffett as CEO at the beginning of 2026. Buffett personally owns 38.4% of the Class A voting shares of Berkshire Hathaway, representing a 15.1% overall economic interest in the company.

Every position this manager reported for the quarter ended 06-30-2026, each as a percentage of the $299.3bn book. Weights are by value, the only unit that compares across different companies.

What changed since 31-mar-2026

Measured in share counts, not value. A position is worth more or less every day as the price moves, so only a change in the number of shares means the manager actually traded. 15 positions were left untouched.

Weights are of the book this manager REPORTED on Form 13F for the quarter, which is the only complete denominator a 13F gives. A 13F covers US listed, long, US custodied positions: cash, bonds, foreign listings, wholly owned businesses and short positions are not in it and are not in these percentages. For an operating company that also runs a portfolio, the reported book is a fraction of the whole enterprise.

The full register, from 13F filings

The Register tab above is hand research: a dozen holders, each traced to the filing it came from. This asks the same question of the whole market for the quarter ended 31-mar-2026, where 4,905 managers reported a position. Broad where the research is deep, and shallow in the ways a 13F always is.

4,905 managers reported a position, together holding 909.7m shares, or 42.5% of the company. The 40 largest are listed. Percentages are of a share count taken later than this quarter, because the count in force at the snapshot is not published as a structured fact for this company. Where the count has moved since, the figures are off by that much.

Built from 13F filings, which report US listed, long, US custodied positions only. A register from this source is a floor rather than a level: a holder's true position can be far larger, as BlackRock's ASML stake shows at 1.28m shares in a 13F against 26.3m in its 13G/A. Holdings held through derivatives, outside US custody, or below a manager's reporting obligation do not appear. Where a holder is marked as a family, its total sums several separate filing entities and describes something no single filing describes; the constituent entities and their share counts are listed so the total can be checked. That roll-up can legitimately exceed the family's own Schedule 13G, because a 13G is filed by one legal entity: Vanguard reports Alphabet through ten advisory entities, and The Vanguard Group Inc itself reported zero after its January 2026 disaggregation.

What the filings say against what the research found

Every holding above was also resolved directly from EDGAR through a precedence rule: the company's own filing outranks a 13D or 13G, which outranks a 13F, which outranks hand research. A 13F reports only US listed, long, US custodied positions, so it is a floor rather than a level. Where sources disagree the higher one leads and the lower is kept beside it.

No position here shows a material gap between sources.
