What Happened

Haitham Khouri, CEO of Perimeter Solutions, sold a total of 229,535 shares in three open-market transactions from May 20–22, 2026, generating approximately $7.28 million in proceeds. The trades were:

  • May 20, 2026 — 20,300 shares at a weighted average price of $34.09, proceeds ≈ $692,027.

  • May 22, 2026 — 117,511 shares at a weighted average price of $31.19, proceeds ≈ $3,665,168.

These were outright sales (S), which are often routine liquidity transactions by insiders and do not by themselves indicate company performance or insider sentiment.
