What Happened
Tomer Weingarten, President, CEO and a director of SentinelOne (S), converted 57,941 shares of Class B common stock into Class A common stock (conversion price $0) and immediately sold those 57,941 shares in the open market. The sales were executed at a weighted average price of $18.75 per share for total proceeds of approximately $1,086,133. This is a sale (liquidity-taking) rather than a purchase.

Key Details

• Transaction date: July 31, 2026; Form 4 filed August 4, 2026 (filed within the standard two-business-day window).
• Sale: 57,941 shares disposed; weighted average price $18.75; total proceeds ≈ $1,086,133. Sales occurred at prices ranging from $18.26 to $19.125 (per footnote).
• Conversion: 57,941 Class B → Class A shares reported as acquired at $0 (conversion) and as a derivative disposition (the converted derivative ceased to exist).
• Plan: Sales were made pursuant to a Rule 10b5-1 trading plan adopted June 3, 2025.
• Forfeiture: Some of the shares may be subject to forfeiture if vesting conditions are not met (per footnote).
• Ownership after transaction: The filing excerpt provided does not state total shares owned after these transactions; net effect here is conversion then sale of 57,941 converted shares.

Context

• Conversion note: Each Class B share converts into one Class A share under the company’s governing provisions; the converted shares were then sold. The derivative "disposed" entry reflects the conversion eliminating the derivative security.
• 10b5-1 plan: Sales under an established 10b5-1 plan are pre-specified and often indicate routine, pre-arranged disposition rather than immediate insider-driven market timing.
• Footnotes: The filing discloses the sale price range and offers to provide per-price breakdown on request, and notes certain holdings are held in an irrevocable trust over which the reporting person has limited powers and disclaims beneficial ownership except to the extent of any pecuniary interest.
