Each DSU represents a right to receive one share once time-based vesting conditions are met, with quarterly vesting and final vesting no later than December 15, 2026, under the company’s deferred compensation program. Following this grant, the director beneficially owns 26,599 shares of Class A common stock directly.
SentinelOne, Inc.'s President and CEO, who also serves as a director, filed an amended insider ownership report to correct a prior share conversion entry.
The amendment reflects that 57,941 shares of Class B common stock were converted into 57,941 shares of Class A common stock at a price of $0, increasing the reporting person's directly held Class A stake to 1,271,037 shares, some of which are subject to forfeiture if vesting conditions are not met. After the transaction, the insider continues to hold 4,092,622 derivative securities linked to Class B common stock, each convertible into one share of Class A common stock under specified conditions.

SentinelOne, Inc. reported that a director received an award of 24,820 restricted stock units (RSUs) of its Class A common stock on December 9, 2025. The RSUs were reported at a price of $0, reflecting that this is a stock-based compensation grant rather than a market purchase.
According to the filing, the RSUs will vest in quarterly installments. Specifically, 1/12 of the total award will vest on each June 30, September 30, December 30, and March 30 following December 9, 2025, and each vesting date requires the director’s continued service. After this grant, the director is shown as directly owning 24,820 shares in the form of these RSUs.
SentinelOne, Inc. disclosed a new insider ownership report showing that a director has filed an initial statement of beneficial ownership on Form 3. The reporting person is identified as a director of SentinelOne, rather than an officer or large shareholder, and the filing is made on an individual basis by one reporting person.
According to the certification section and related remarks, the director reports that no securities are beneficially owned, meaning they do not currently hold SentinelOne stock or derivative securities in reportable form as of the event date of 12/03/2025. The Form 3 is signed by an attorney-in-fact on 12/11/2025, confirming the accuracy of the disclosure under federal securities law.

On 12/08/2025, the officer sold 8,311 shares of Class A common stock at $14.58 per share.

Following this transaction, the officer beneficially owned 565,225 shares of Class A common stock. The disclosure notes that certain of these shares remain subject to forfeiture if the underlying vesting conditions are not met, reflecting ongoing performance or service-based requirements attached to the awards.
