Raj Vivek 4

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.

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.
