Khouri Haitham 4

What Happened

• Haitham Khouri, CEO of Perimeter Solutions (PRM), reported the vesting/acquisition of 588,489 shares of common stock on February 26, 2026. The filing shows three derivative awards converted to common shares: 88,489; 100,000; and 400,000 shares. Each acquisition is reported at $0.00 per share (award/vesting of previously granted options), so no cash purchase was reported on the Form 4.

Context

• These were performance-based option vestings (derivative securities converting to common stock) tied to multi-year performance criteria from prior grants; the Form 4 reports the vesting/acquisition rather than a cash purchase or market sale.
• Vesting/awards reported at $0.00 do not mean no market value — they reflect that shares resulted from option vesting/awards rather than an open-market transaction. This type of filing documents compensation-related equity accruals rather than a directional insider buy or sell.
