What Berkshire Hathaway reported

What was reported: 89 source rows. No PUT/CALL-designated rows.
The clearest takeaway: AMERICAN EXPRESS CO is the largest individual row without a PUT/CALL designation, at $50,419,898,471. Inspect the table.
Why it may matter: 15 holdings kept an identical reported share count across both quarters while their reported value changed.
What it does not prove: Positions held today, trade dates, conviction, or a complete view of the manager’s assets and risks.

Buteon’s filing assessment

What stands out: 89 filed rows provide a dated record of disclosed exposure.
How readable is it?: The reported quantities can be read directly. Inferring trades still requires separate comparison checks.
Is it fresh?: Latest complete reporting period, but measured on Jun 30, 2026. Useful as a disclosure record; stale as a claim about positions held today.

The reported record

Largest rows without a PUT/CALL designation

Ranked by reported value; up to 20 individual source rows. Repeated securities stay separate because manager relationships can overlap. SH means shares; PRN means principal amount. This section can include instruments other than common stock.

Options, separately

This filing reports no PUT/CALL-designated rows. That does not establish that the manager has no derivatives outside Form 13F.

One filing lesson

Fifteen holdings did not move. Their value did.

Reported value can change even when share counts do not. Compare share quantities only after the source rows have been cleared for comparison.

Read as text: CHEVRON CORPORATION reports the same 3,454,258 shares in both quarters, while value changes from $714,685,980 to $572,577,806. That is not evidence of additional buying. No dollar attribution between share and price effects is claimed.

Filing Reality Check · eleven evidence questions

The instrument every dossier uses

The eleven questions, in the fixed order.

#	Question	Answer	Evidence class
1	What was reported	89 individual information-table rows. Options remain separate.	Filed fact
2	Who filed it	BERKSHIRE HATHAWAY INC, CIK 1067983, file 028-04545.	Filed fact
3	When it was true	Jun 30, 2026	Filed fact
4	When it went public	Aug 14, 2026	Filed fact
5	Filed facts	Quantities, values, security classes, option sides, discretion, voting fields and included managers.	Filed fact
6	What we calculated	Row rankings and composition percentages against this filing’s own totals; only specifically cleared share comparisons.	Verified derivation
7	Instrument & rules	Form 13F is a delayed record of reportable securities. It omits short stock and written options.	Interpretation
8	How clear, and why	The source rows are readable; intra-quarter trades and present holdings remain unknown.	Interpretation
9	What it can't show	Trade dates, full assets under management, current positions, net exposure or conviction.	Unresolved
10	What would help	Corporate-action review, manager-relationship clearance and newer primary disclosures.	Interpretation
11	The filings behind it	Current 0001193125-26-352200; prior 0001193125-26-226661. No Form 13F-HR/A amendment was found for either quarter in EDGAR submissions reviewed through Sep 25, 2026. An amendment filed later could change these rows.	Filed fact

Concentration depends on what you count

Top five securities and top five issuers answer different questions. Both use the same reported total; they do not measure all Berkshire assets.

Four ways to say “the top five,” and they are not the same number. Every figure shows the document it came from, the grain it was aggregated at, the denominator it was divided by, and whether it is a filed fact or our calculation.
Figure	Source document	Aggregation grain	Denominator	Evidence class
68.6515%	Form 13F-HR 0001193125-26-352200	Filing rows aggregated to CUSIP	$299,253,556,246 reported table total	Verified derivation
71.8616%	Form 13F-HR 0001193125-26-352200	Share classes combined by issuer	$299,253,556,246 reported table total	Verified derivation

Methodology & corrections

The source stays beside the claim.

SEC Form 13F cover pages and information tables are the numerical authority. We reconcile every accepted table to its cover, retain each source row, and keep options separate. Reported values are whole US dollars. We do not add holdings across filers or estimate an ownership percentage.

A matching security identifier alone is not enough for a quarter comparison. Until amendments, corporate actions and manager relationships are cleared, the result is “not comparable.” A newly reported row need not be a new purchase, and a missing row need not prove a sale.

How to read Form 13F · SEC methodology and filing calendar · Report a correction

Data version 2026-q2.2026-09-25.4. Review cutoff 2026-09-25. Corrections require a primary source and a new reviewed data version.

Holdings are one piece of the picture

A filing answers what was reported. The next question is what matters.

Is it new or routine? Is it still fresh? What other public evidence supports it—and what happened after similar signals? Buteon is being built to connect those questions across filings, company events and market context.

Institutional filings are designed to become one evidence class in Buteon’s broader intelligence framework. This curated research surface shows what the filings establish today; it does not feed production company verdicts or provide automated institutional alerts.
