PRM Perimeter Solutions, Inc. Insider Trading

CEO Haitham Khouri sold 229,535 shares for $7,284,107.93 across 3 sales May 20-22 at $31.19–$34.09

Haitham Khouri, CEO of Perimeter Solutions, Inc., executed 3 separate sales totaling 229,535 shares for $7,284,107.93 at a blended average price of $31.73, reducing his holdings from 2,104,150 to 1,874,615 shares (a -10.9% reduction). The timing of these sales warrants attention: they were executed as the stock traded between $34.09 and $31.19, and the company reported a recent quarterly net income of $72,936,000.00 on revenue of $125,069,000.00, though it was unprofitable for the full fiscal year. Notably, across Khouri's cross-ticker track record, his prior 3 sells achieved a 100.00% well-timed rate at the 90-day mark (average 90d return -1.9%), and his 3 prior sales at PRM showed consistent patterns: all 3 were well-timed at the 90-day mark with negative returns (-1.7%, -3.0%, -0.8%). The current price of $31.10 reflects only a modest divergence from the transaction prices, but the historical consistency of Khouri's selling patterns at this ticker and his demonstrated track record of selling ahead of subsequent declines provide context for monitoring this filing's post-transaction price trajectory.

CFO Sable Kyle liquidates entire 49.5K share position in PRM across 3 separate sales for $1.6M on 2026-05-13

Sable Kyle, Chief Financial Officer of Perimeter Solutions, executed a complete liquidation of his shareholdings through 3 separate sales totaling 49,540 shares for $1,639,066.58 on 2026-05-13. The stock currently trades at $33.23, approximately -4.8% from its 52-week high of $34.89, having gained +22.4% over the past 30 days and +26.7% over the past 90 days. Among his prior 5 sales at PRM, four of the five trades (2026-05-12, 2026-05-11, 2026-05-08, and 2025-09-05) subsequently posted 90-day returns in the +1.2% to +7.9% range, with only one prior sale showing a 90-day decline (-19.0% on 2025-12-12). The complete elimination of his stake during a period of recent stock strength and near 52-week highs merits investor attention, particularly given that prior sales at this ticker have predominantly been followed by positive longer-term returns.

PRM President Emery Jeffrey sells entire remaining stake (53.5K shares) in 2 transactions for $1.8M; stock up 22.4% in 30 days

Emery Jeffrey, President of Global Fire Safety at Perimeter Solutions, executed 2 separate sales totaling 53,537 shares for $1,790,812.65 on 2026-05-13, reducing his holdings to zero. The sales occurred at $8.36 and $33.45 per share—the latter near the 52-week high of $34.89—as the stock has appreciated 22.4% over the prior 30 days and 26.7% over 90 days. Across his same-ticker history at PRM (4 prior sales), only 1 of 4 prior sales proved well-timed at the 90-day mark, suggesting limited predictive accuracy on this specific stock. The complete liquidation of a significant executive stake merits investor attention given the magnitude and the timing coinciding with recent strength, though the insider's cross-ticker timing record (25.00% well-timed rate) and fundamentals ($125.1M quarterly revenue, strong 16.4% annual growth) provide limited directional clarity on near-term outlook.

President exercises 146K shares and immediately liquidates entire position for nearly $4.8M in matched buy-then-sell pairs.

Emery Jeffrey, President of Global Fire Safety at Perimeter Solutions, exercised approximately 146,000 shares over two trading days and sold the full position through three separate transactions for a total disposition value near $4.8 million. Both transactions on each day paired an exercise (at below-market prices) with an immediate sale at prevailing market prices, creating a mechanical gain with no capital exposed. The stock is currently trading at its 52-week high after a significant recent rally, which means Jeffrey is exiting when the stock has appreciated most sharply. His single prior sale at this company, executed several months earlier, proved poorly-timed — the stock subsequently gained significantly — yet the current pattern replicates that same dynamic: selling into strength rather than into weakness. The company remains unprofitable on an annual basis despite recent quarterly earnings, putting this liquidation in the context of a financially stressed business that has nonetheless rallied sharply in recent weeks.

CFO executes three sales totaling $6.4M in May, offsetting simultaneous stock option exercises—net position unchanged after 36-month selling pattern.

Sable Kyle, Perimeter Solutions' Chief Financial Officer, executed a complex three-part sale strategy over four trading days in early May, liquidating roughly $6.4 million in shares. These sales were perfectly offset by stock option exercises occurring on the same dates, resulting in zero net change to her ownership—a common pattern for executives managing tax or liquidity around compensation vesting. What stands out is the scale: this filing adds three open-market sales to her 36-month record, bringing her total to five sales and zero open-market purchases, establishing a consistent pattern of liquidation. Her track record in this stock shows mixed timing results—one prior sale in late 2025 caught the stock before a decline (well-timed), while an earlier 2025 sale preceded a meaningful rally (poorly-timed)—leaving her credibility on exits unsettled. The stock currently trades near its 52-week highs after gaining sharply over the past month, which provides context for the timing: she is selling into strength after a substantial rally, though whether that marks a strategic exit or routine equity vesting remains ambiguous given the simultaneous exercises.
