Insights

Corporate Governance Analyst

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.

Regulatory Compliance Specialist

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/A regulatory

"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.

"Item 5. | Ownership of 5 Percent or Less of a Class."

Exhibit A regulatory
