PEEK MARK S 4

What Happened
Mark S. Peek, a non-employee director of SentinelOne, received two equity awards on June 25, 2026: 4,746 deferred restricted stock units (DSUs) and 14,238 restricted stock units (RSUs). Both grants were reported as acquisitions (code A) at $0.00 per share (typical for RSU/DSU awards); total shares granted = 18,984. These are awards/compensation — not open-market purchases or sales.

Key Details

• Transaction date and price: June 25, 2026; grant price $0.00; transaction code A (award/grant). Form filed June 26, 2026 (appears timely).
• Vesting for the 4,746 DSUs: time-vests 25% on each of Sept 15, Dec 15 and Mar 15, with the final quarterly installment vesting on the earliest of (i) the next annual meeting, (ii) immediately prior to that meeting if the director is not re‑elected or does not stand for re‑election, or (iii) June 15, 2027 — all subject to continued service. Settlement of DSUs was deferred per the director’s election under the Company’s Program.
• Vesting for the 14,238 RSUs: entire award vests and settles on the earliest of (a) June 25, 2027, (b) the next annual meeting (or immediately prior if not re‑elected), (c) the director’s death, (d) disability, or (e) a change in control — subject to continued service.
• Some awarded shares are subject to forfeiture if vesting conditions are not met.
• Certain reported securities are held directly by an irrevocable trust with a third‑party trustee (beneficiary: a child of the reporting person).
• Shares owned after the transaction are not disclosed in this Form 4.

Context
These awards are director compensation and are routine for non‑employee directors; they do not reflect an open‑market purchase (which some investors view as a stronger bullish signal). DSUs are deferred rights to receive shares at settlement dates — they are not immediately tradable stock.
