Marc Prieur sold 5,000 shares across 2 separate transactions on 2026-06-09 at blended average price $115.58, reducing his ATR holdings by 20.6% from 24,323 to 19,323 shares. The transaction occurred as the stock trades at $114.71 current price, down 4.4% over 30 days and 11.0% over 90 days from the transaction date, representing 30.2% below the 52-week high of $164.28. At the same-ticker level, Prieur's prior 3 measurable ATR sales show mixed timing: 2 of 3 were well-timed at the 90-day mark (negative returns after sale), but his most recent ATR sale on 2025-05-20 captured only -5.5% at 30 days before a steeper -12.9% 90-day decline. The sale occurs against solid fundamentals (P/E 18.93, annual revenue growth +5.4%, latest quarter revenue $982.9M), suggesting the transaction reflects portfolio management rather than broad operational concern.

Marc Prieur, Segment President of Aptar Group, sold 6,000 shares (25.3% of his pre-transaction holdings) on 2025-05-20 at $158.34, reducing his stake from 23.7K to 17.7K shares for proceeds of $950.0K. The sale occurred near Aptar's 52-week high of $176.15, though the current price of $156.45 is down 11.2% from that peak. Examining his prior sales at Aptar across four prior transactions, only 1 of 4 was well-timed at the 90-day mark, suggesting inconsistent execution in predicting short-term downturns at this specific ticker. His cross-ticker track record shows an average 90-day return of +3.0% after prior sells with a 25.00% well-timed rate, indicating his selling decisions have not consistently preceded declines across his broader portfolio activity. The company's modest 2.7% annual revenue growth and elevated P/E of 27.89 provide limited context for insider motivation given the absence of earnings surprises or material guidance changes in the transaction date window.

At the same-ticker level, his prior two measurable sales (2024-08-29 and 2023-08-07) each posted positive 30-day returns (+5.0% and +4.5% respectively), suggesting his recent sells have preceded price strength rather than declines. His cross-ticker track record shows an average 90-day return of +2.6% after sells with a 0.00% well-timed rate, indicating a pattern of selling into or just before rallies.

His broader cross-ticker track record shows 2 prior sells with an average 90-day return of +2.6% and a 0.00% well-timed rate, reflecting a consistent pattern of sales followed by gains. This sale occurs at elevated valuations (P/E 31.59, market cap $10.1B) in a company with solid recent fundamentals (annual revenue growth +5.0%, $910.1M latest quarterly revenue). The absence of any scheduling or plan disclosure suggests this is a discretionary transaction. The consistent pattern of post-sale gains in both cross-ticker and same-ticker history provides context for monitoring whether this trade represents a departure from that pattern.
