Insights

Financial Analyst

TL;DR: Large insider purchases totaling 5.03M SIRI shares at ~ $21 increase Berkshire's indirect stake to 124.8M shares.

These reported purchases — 1,977,837; 85,389; 1,930,000; and 1,037,199 shares on 07/31/2025, 07/31/2025, 08/01/2025 and 08/04/2025 respectively — total 5,030,425 shares acquired at weighted-average tranche prices of $21.0436, $21.4305, $21.0228, and $21.6252. The filings show indirect ownership rising to 124,807,117 shares as of Aug 4, 2025. For investors, concentrated purchases by Berkshire-affiliated entities can signal incremental demand and conviction; the absolute scale (over 124M indirect shares) is material to ownership disclosure.

Corporate Governance Expert

TL;DR: Significant acquisitions are reported but many shares are held indirectly and Buffett disclaimers limit direct beneficial-ownership implications.

The Form 4 discloses that 108,822,227 shares are owned by Berkshire subsidiaries and 15,984,890 by pension plans. Warren E. Buffett "disclaims beneficial ownership" except to the extent of his pecuniary interest. That legal disclaimer and the indirect ownership structure moderate the governance signal; filings document activity but do not establish direct, sole personal control of the purchased shares by Mr. Buffett.
