PADGETT BARRY L. 4

What Happened
Barry L. Padgett, Interim Chief Financial Officer of SentinelOne (S), had the first tranche of a 2025 performance-based restricted stock unit (PRSU) award certified and settled on March 23, 2026 (92,662 RSUs earned and vested at 90.2% of target). On March 25, 2026 he sold 32,221 of those shares in an issuer-mandated "sell-to-cover" transaction at $13.37 per share, generating $430,795. The sale was to satisfy tax withholding and was not a discretionary trade by the reporting person.

Context
Performance RSUs vest based on pre-determined corporate performance milestones and continued service; the first tranche was certified by the compensation committee and settled for shares on the certification date. Sell-to-cover transactions to satisfy withholding are common and reflect tax obligations at vesting rather than a voluntary decision to reduce holdings.
