Berkshire Hathaway and related entities amended a Schedule 13G/A reporting ownership in POOL CORPORATION common stock. The filing lists the reporting persons (Warren E. Buffett; Berkshire Hathaway Inc.; National Indemnity Company; GEICO Corporation; Government Employees Insurance Company) and states ownership of 5 percent or less of the class under Item 5. The cover-page lines shown report 0.00 for sole and shared voting and dispositive power and an ownership figure of 0% for the listed entries. Signatures are dated 05/15/2026, with an apparent cover date of 03/31/2026.

Insights
Schedule 13G/A amendment records passive, sub-5% holdings by Berkshire-related filers.
The filing names Warren E. Buffett and several Berkshire Hathaway affiliates and lists their addresses and citizenships while stating under Item 5 that ownership is "5 percent or less of a class." The cover-page lines shown indicate 0.00 voting and dispositive power and an ownership entry of 0%.
Because the filing is an amendment to a 13G-type disclosure, it reflects passive reporting obligations rather than active control; subsequent filings would disclose any material changes in holdings.
Document is procedural: identifies reporting persons and attaches required exhibits for group/subsidiary classification.
The schedule provides issuer details (POOl CORPORATION address) and instructs that cover pages and Exhibit A supply subsidiary and group classification information. The signature block shows multiple attestations by Warren E. Buffett dated 05/15/2026.
Filing-level implications are administrative: stakeholders can verify that the reporting persons met the 13G disclosure thresholds; any shifts above 5% would trigger different reporting requirements.

Schedule 13G/Aregulatory
"Amendment No. 2 ) POOL CORPORATION Common Stock"
A Schedule 13G/A is an amended public filing with the U.S. securities regulator that updates a previous Schedule 13G, disclosing when an individual or group holds a substantial (typically over 5%) stake in a company and is claiming a passive, non‑controlling intent. Investors monitor these updates because rising or falling holdings can signal changing confidence, potential future moves, or shifts in voting power — like watching a public ledger where large shareholders quietly adjust their positions.
