Perimeter (PRM) Director Raj Vivek Receives 28,944 Shares from Option Vesting

What Happened
Raj Vivek, a director of Perimeter Solutions, had portions of multiple previously granted stock option awards vest on February 26, 2026, resulting in an aggregate reported acquisition of 28,944 derivative shares at $0.00 (i.e., vesting of options rather than an open-market purchase). The vesting amounts come from five prior option grants (2021–2025) whose 2025 performance criteria were met or partially met, producing vestings of 6,194; 7,000; 7,000; 7,000; and 1,750 shares respectively.

Key Details

  • Transaction date: February 26, 2026; Form 4 filed March 2, 2026 (filed within the two-business-day Form 4 window, timely).
  • Aggregate shares reported acquired: 28,944; reported price: $0.00 (derivative/vesting of options).
  • Shares owned after transaction: Not specified in the filing.
  • Footnotes: Each amount reflects vesting from prior option grants:
    • 2/12/2025 grant (35,000) — 6,194 vested (partial vesting).
    • 2/14/2024 grant (35,000) — 7,000 vested.
    • 2/15/2023 grant (35,000) — 7,000 vested.

    • 12/7/2021 grant (8,750) — 1,750 vested.
  • No indication in this filing of an immediate exercise, sale, 10b5-1 plan, or tax-withholding sale.

Context
These entries reflect performance-based option vesting (compensation/TLTI), not an open-market buy or sale. Vesting signals fulfillment of specified 2025 performance metrics for those grants; it does not itself indicate that shares were sold or that cash changed hands. Any subsequent exercise of the options or market transactions would be reported separately on future Form 4 filings.
