[Form 4] Samsara Inc. Insider Trading Activity

Rhea-AI Filing Summary

Samsara insider holdings and transfers involving multiple Andreessen Horowitz entities are reported. On September 8, 2025 several AH-related funds distributed large blocks of Class A common stock to their limited partners for no consideration: Andreessen Horowitz Fund IV Entities distributed 10,949,014 shares; AH Parallel Fund V Entities distributed 2,316,745 shares; AH LSV Fund I Entities distributed 1,255,907 shares; AH Parallel Fund IV Entities distributed 994,899 shares. Related entities (including a16z Capital and the 1997 Horowitz Family Trust) show acquisitions of certain shares, and multiple Form 4 sales on September 9, 2025 report disposals at weighted-average prices roughly in the $37.38–$40.10 range. The filing is one of three split filings covering many reporting persons and discloses voting/dispositive power and disclaimers of group ownership.

The transactions reflect internal distributions to limited partners and subsequent market sales by reporting entities; the report provides weighted-average sale prices and undertakes to supply per-price allocation on request.

Positive

• Large pro rata distributions were completed to limited partners, demonstrating an orderly internal allocation process
• Detailed disclosure of weighted-average sale prices and offers to provide per-price allocation enhances transparency
• Voting and dispositive power attributions and disclaimers are clearly stated for related GP entities

Negative

• Significant disposals reported (e.g., 10,949,014 shares disposed by AH Fund IV Entities) which materially reduced certain funds' reported holdings
• Post-distribution secondary sales at prices ~ $37.38–$40.10 increased public float and may exert downward share-pressure depending on volume

Insights

Securities Analyst

TL;DR: Large pro rata distributions by multiple a16z funds and notable secondary-market sales reduce certain fund holdings and increase public float.

The filings show coordinated internal distributions on September 8, 2025 totaling tens of millions of Class A shares across multiple Andreessen Horowitz-related funds, followed by sales reported on September 9, 2025 at weighted-average prices between approximately $37.38 and $40.10. The single-event split into three Form 4 filings is administrative due to the number of reporting persons. For investors, the key items are the scale of the distributions (for example, 10,949,014 shares from Fund IV Entities) and the sales that followed, which materially lowered reported beneficial ownership for several funds. The filing includes standard disclaimers about voting/dispositive power and offers to provide per-trade price details on request.

Corporate Governance Expert

TL;DR: Transactions are structured distributions to limited partners with accompanying disclosures; governance disclaimers and voting-power attributions are clearly stated.

The report documents distributions 'for no consideration' from multiple Andreessen Horowitz funds to their limited partners and affiliated entity distributions to members, consistent with internal reallocation of holdings rather than third-party transfers. The filing discloses which general partner entities may be deemed to have voting and dispositive power and includes customary disclaimers denying formation of a group. Splitting the report across three Form 4s addresses EDGAR limits and preserves transparency. These are material ownership and disposition disclosures but reflect fund-level restructuring and subsequent secondary sales rather than operational or strategic changes at the issuer.
