[Form 4] Red Rock Resorts, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Form 4 highlights: Berkshire Hathaway Inc. and Warren E. Buffett, both deemed 10% owners of Sirius XM Holdings (SIRI), disclosed fresh open-market purchases of the issuer’s common stock.

Transactions: Between 31-Jul-2025 and 04-Aug-2025 they bought 5,030,425 shares in four tranches: 1,977,837 sh at $21.0436, 85,389 sh at $21.4305, 1,930,000 sh at $21.0228 and 1,037,199 sh at $21.6252 (weighted-average prices; detailed price ranges supplied in footnotes).

Resulting ownership: Indirect holdings rose to 124,807,117 SIRI shares. Of this total, 108,822,227 shares are held by Berkshire insurance subsidiaries (GEICO, National Fire & Marine, National Indemnity) and 15,984,890 shares by pension plans of Berkshire subsidiaries. Buffett disclaims beneficial ownership except to the extent of his pecuniary interest.

Implications: The 4%+ increase in position reinforces Berkshire’s strategic exposure to SIRI and signals continued confidence from Buffett’s conglomerate while keeping the stake above the 10% threshold that triggers ongoing Section 16 reporting.

Insights

Securities Analyst

TL;DR: Berkshire bought 5.0 M SIRI shares, lifting stake to 124.8 M; purchase suggests incremental confidence, modest but positive signal.

Perspective: A 5 M-share addition raises Berkshire’s exposure by roughly 4 %, pushing its indirect ownership to 124.8 M shares. The buying window at ~$21 is near recent trading ranges, implying conviction rather than bargain hunting. Because Berkshire already exceeded the 10 % threshold, regulatory burden stays unchanged. While the dollar amount is small relative to Berkshire’s $300 B+ equity portfolio, Sirius XM benefits from the reputational endorsement. No immediate operational or financial impact on SIRI, yet the purchase may ease investor concerns about subscriber softness by showcasing an informed, long-term holder adding shares.

Corporate Governance Expert

TL;DR: Additional purchases keep Berkshire aligned with insider-ownership incentives; no governance red flags.

Buffett’s conglomerate continues to hold SIRI through multiple insurance entities and pension trusts, preserving a diversified indirect structure. All trades were properly disclosed via Form 4 within two business days, indicating compliance with Section 16. The filing reiterates Buffett’s disclaimer of beneficial ownership beyond pecuniary interest, a standard governance stance that limits fiduciary conflicts. The absence of derivative activity or dispositions suggests a straightforward long equity thesis. Overall, the event is governance-neutral to positive, reflecting transparent reporting and sustained insider alignment.
