Monitor for additional Form 144 or Form 4 filings from insiders, especially current executives. The concentrated selling by a former affiliate is not alarming by itself but could precede broader insider distribution. Watch next earnings release for any guidance changes that might explain the selling pattern.
Price Chart
Executive Summary
Susan L. Bostrom, a former affiliate of Samsara Inc., filed a Form 144 notice of intent to sell 75,000 shares of common stock, valued at approximately $3.03 million based on the filing date. This follows three prior sales by the same insider in the past two weeks totaling ~117,403 shares (~$4.48M), bringing the aggregate recent selling to ~192,403 shares (~$7.5M). While the amounts are small relative to Samsara's $22.3B market cap, the pattern of concentrated insider selling warrants attention.
Key Facts
- Form 144 filed 08/07/2026 by former affiliate Susan L. Bostrom for 75,000 shares of common stock.
- Approximate market value of proposed sale: $3,031,838.
- Shares were acquired via restricted stock lapses and equity compensation between 12/15/2023 and 03/15/2025.
- Bostrom has sold 37,403 shares on 07/28/2026 ($1,397,474), 50,000 shares on 07/29/2026 ($1,930,058), and 30,000 shares on 08/04/2026 ($1,147,501) — totaling ~117,403 shares (~$4.48M) in the prior two weeks.

- Samsara's market cap is $22.3B; the proposed sale represents ~0.014% of market cap.
Financial Impact
Proposed sale of 75,000 shares (~$3.03M) is immaterial to Samsara's $22.3B market cap. However, the insider's cumulative recent selling of ~$7.5M in two weeks is a modest signal.
Risk Factors
- Insider selling pattern may indicate reduced confidence, though the seller is a former affiliate, not current management.
- Further insider sales could pressure the stock in the near term.
