SentinelOne, Inc. (NYSE: S) reported a mandated insider sale this week as President and Chief Executive Officer Tomer Weingarten sold 72,523 shares of the company’s Class A common stock on March 25, 2026. The shares transacted at $13.37 apiece for a total of $969,632, according to a Form 4 filing with the Securities and Exchange Commission.
The filing makes clear the disposition was not discretionary. SentinelOne stated the sale was executed to cover tax withholding obligations arising from the vesting and settlement of performance-based Restricted Stock Units (RSUs). That mechanism - selling vested shares to meet tax liabilities - was cited explicitly in the Form 4 as the reason for the trade.
Market data shows SentinelOne’s shares are trading at $13.36, and the company carries a market capitalization of $4.54 billion. The stock has declined 8.2% over the past week.
The insider sale follows closely on related equity activity executed earlier in the week. On March 23, 2026, Weingarten received two issuances of Class A common stock: one for 39,405 shares and another for 102,416 shares. These issuances were tied to certification of achievement for tranches of performance-based restricted stock unit awards; the company’s compensation committee certified the achievement of certain performance tranches, triggering the settlements.
