Key questions

• How does the size of this transaction compare to Mr. Weingarten’s historical selling activity?
  This sale of 39,472 shares is smaller than the recent median sell-only transaction of 60,864 shares, based on 36 sell trades since August 2024, and represents a slightly higher proportion of direct holdings (3.52%) than the recent median of 2.73% per trade.
• What is the impact on Mr. Weingarten’s ownership position following this transaction?
  Direct ownership declined to 1,083,073 shares post-sale, with no indirect or derivative holdings reported, equating to a remaining direct stake valued at approximately $14.75 million as of Feb. 11, 2026.
• Does the filing indicate any unusual cadence or deviation from prior trade patterns?
  Given the remaining holding now represents only about 18% of Mr. Weingarten’s April 2023 position, the sale size relative to current capacity is in line with the pattern of shrinking trade size as total available shares decline.
• Were any derivative securities or indirect entities involved in this disposition?
  No options, warrants, or indirect holdings via trusts or similar entities were reported in this transaction; all shares sold were direct holdings of Common Stock.

What this transaction means for investors

CEO Tomer Weingarten’s sale of 39,472 SentinelOne shares is not a red flag. He executed the trade as part of a Rule 10b5-1 trading plan he adopted in June of 2025. Insiders frequently establish such plans to prearrange trades and avoid accusations of acting on insider information.

Moreover, he still has over one million shares after this transaction, indicating he is in no rush to dispose of his holdings. The trade comes at a time when SentinelOne stock is beaten down. Shares reached a 52-week low of $12.43 on Feb. 9, a couple of days before Mr. Weingarten’s sale.

SentinelOne operates in a competitive space against large rivals. Its use of artificial intelligence to differentiate its platform doesn’t stand out in an era where many cybersecurity companies are embracing AI.

However, SentinelOne forecasted sales for its 2026 fiscal year, ended Jan. 31, will reach $1 billion for the first time. That’s a healthy increase over fiscal 2025’s $821.5 million.

With its stock price drop, SentinelOne’s price-to-sales ratio of four hovers around a multi-year low point. This suggests it’s at an attractive share price valuation, making now a good time to buy but not to sell.
