SentinelOne CEO sells $2.29 million in shares as stock closes in on its yearly high
Tomer Weingarten sold 114,890 Class A shares while continuing to hold millions of shares across both stock classes.
SentinelOne CEO Tomer Weingarten sold approximately $2.29 million worth of the cybersecurity company's Class A shares on September 11, as the company's stock continues a strong run that has lifted its market value to nearly $8 billion.
Weingarten sold 114,890 Class A shares at a weighted average price of $19.8899, with individual transactions ranging from $19.72 to $20.22. The sale was carried out under a Rule 10b5-1 trading plan that Weingarten adopted on June 3, 2025.
The timing is notable because SentinelOne shares have risen sharply this year. The stock was up 56.5% year to date through September 15 and closed that day at $23.48, just below its 52-week high of $23.95. SentinelOne's market capitalization stood at $7.87 billion as of September 14.
Weingarten's sale, however, does not by itself indicate that he made a new decision to sell in response to the recent rise in the stock. The 10b5-1 plan governing the transaction was adopted more than a year before the September sale, allowing the transaction to be arranged in advance.
The filing also shows that Weingarten was not simply reducing his exposure to SentinelOne. On the same day, he acquired 57,941 Class A shares through the conversion of Class B common stock. The conversion involved no monetary transaction.
Following the transactions, Weingarten directly held 1,744,878 Class A shares. Some of those shares are subject to forfeiture if their underlying vesting conditions are not met.
He also directly held 3,421,153 Class B shares, which are convertible into Class A shares. An irrevocable trust holds another 423,629 Class B shares.
The stock's rise has come as SentinelOne has reported results that exceeded Wall Street expectations on several measures. In its second-quarter fiscal 2027 results, the company reported revenue, operating margin and annual recurring revenue above FactSet consensus. Revenue exceeded expectations by 0.6%, while ARR was 0.4% above consensus.
