ATR APTARGROUP, INC. Insider Trading

Segment President Marc Prieur sells 5,000 shares (20.6% reduction) at $115.58 avg; stock down 4.4% in 30 days.

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.

CAO Daniel Ackerman sells 15,000 ATR shares at $121.23; holdings reduced 33.6% to 29,607 shares

Daniel Ackerman, Chief Accounting Officer of Aptargroup, sold 15,000 shares at $121.23 on 2025-12-12, reducing his holdings by 33.6% from 44,607 to 29,607 shares for a total value of $1,818,435.00. The sale occurred when the stock was trading at $121.23, which is 29.0% below the 52-week high of $172.31, though up 3.1% over the prior 30 days. As Chief Accounting Officer, Ackerman's transaction warrants attention from investors tracking leadership portfolio activity, though the significance is moderate given the company's stable fundamentals (P/E of 19.14, $961.1M latest-quarter revenue, $127.9M net income, +2.7% annual revenue growth) and $8.0B market capitalization. The 33.6% reduction in his personal holding represents a material decrease in his exposure and may be part of regular financial planning rather than a statement about company outlook, but investors should monitor whether other executives follow suit or provide context in upcoming disclosures.

Segment President Touya Gael sells 3,300 shares of ATR for $503,653.86 on 2025-06-06; holdings remain substantial at 34.0K shares.

Touya Gael executed 2 separate sales totaling 3,300 shares for $503,653.86, at prices close to the blended average of $152.62 per share. The transaction represents an 8.9% reduction from his pre-transaction holdings of 37.3K shares, leaving him with substantial equity stake of 34.0K shares in the company. At his prior trade on 2025-09-09 at this ticker, the 90-day return was +12.9%, indicating the stock moved upward after that sale, suggesting the prior sale was not well-timed. The current stock price of $151.60 is 13.9% below the 52-week high of $176.15, and ATR trades at a P/E of 27.02 with recent quarterly revenue of $887.3M and net income of $78.8M. The filing contains no red flags from a fundamental deterioration perspective; this appears to be a modest reduction of a sizable position by a senior executive.

Gong Xiangwei (ATR President, Asia) sold 7,000 shares ($1.1M) at $156.49; holds 10,265 post-transaction

Gong Xiangwei sold 7,000 shares (40.5% reduction in holdings) at $156.49, bringing his position to 10.3K shares. The transaction occurred when ATR was trading -11.5% below its 52-week high of $176.15, and recent momentum has been positive (30-day +5.3%, 90-day +6.6%). His prior sell at ATR on 2024-08-15 showed a positive 90-day return of +19.8%, indicating the stock rose after that sale—the opposite of well-timed selling. With a cross-ticker track record showing 0 of 1 prior sells well-timed at the 90-day mark and this ticker showing identical poor timing on the prior trade, the sale does not align with a pattern of prescient exits. The company's fundamentals remain solid: $887.3M quarterly revenue, +2.7% annual growth, $78.8M net income, and a P/E of 27.80.

Segment President Marc Prieur sold 6,000 ATR shares at $158.34; now holds 17.7K shares post-transaction.

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.

Segment President Tlili Hedi sold 3,614 shares of ATR at $155.96 for $563,642.33; post-sale holding 9,379 shares, down 27.8%.

Segment President Tlili Hedi executed a sale of 3,614 shares on 2025-05-16 at $155.96, reducing his stake by 27.8% to 9,379 shares post-transaction. The sale occurs with ATR trading at $158.08 currently, approximately 1.4% above the transaction price, and within 10.3% of the 52-week high of $176.15. Reviewing his ticker-specific history at ATR, both prior sells on 2024-05-01 resulted in positive 90-day returns (+0.5% and +0.4%), indicating that neither of those sales preceded a decline—the stock rose after both. His cross-ticker track record shows 2 prior sells across all holdings with an average 90-day return of +0.5% and a well-timed rate of 0.00%, reflecting no pattern of selling ahead of downturns. The transaction is material in size relative to his pre-sale holdings, but the absence of a pattern suggesting foresight into price weakness, combined with the stock's recent upward momentum (+9.9% over 30 days), limits the signal content for investors.

CEO Stephan B. Tanda sells 18,671 shares for $2,824,545.02 in 3 transactions over May 6–7

Tanda Stephan B., President and CEO, executed three separate sales totaling 18,671 shares (18.7K shares) for $2,824,545.02 ($2.8M) at a blended average price of $151.28, reducing his holdings from 223,657 shares to 204,986 shares (-8.3% of pre-transaction holdings). At the same-ticker level, his prior four measurable trades at ATR show a 3-of-4 well-timed pattern at the 90-day mark, with outcomes including +14.2%, -6.5%, -7.0%, and -7.4%; the most recent prior sell on 2025-05-05 is still awaiting measurable outcome. His cross-ticker track record across 9 prior sells shows a 50.00% well-timed rate with average 90-day returns of +3.8%, indicating mixed historical timing accuracy. The stock currently trades at $151.39, -14.1% from its 52-week high of $176.15 and up +12.4% over the past 30 days, placing this sale within a near-term uptrend but well below recent peaks.

CEO Tanda Stephan B. sold 11,329 shares of ATR at $152.39 on 2025-05-05, retaining 204,986 shares post-transaction.

Tanda Stephan B., President and CEO, executed a $1,726,422.91 sale reducing his stake by 11,329 shares (-5.2% of holdings), leaving him with substantial remaining position of 204,986 shares. His same-ticker history at ATR shows 3 of 4 prior measurable sells were well-timed at the 90-day mark, with negative returns after sale dates in three consecutive October 2024 transactions. However, this cross-ticker track record (50.00% well-timed rate across 9 prior sells, avg 90d return +3.8%) is modest and the stock currently trades -14.3% from its 52-week high despite 30-day strength of +7.7%, indicating recent volatility. The sale timing relative to price momentum and subsequent performance will be informative for assessing this particular decision in context of the insider's broader patterns.

Segment President Marc Prieur sold 4,000 shares of ATR at $168.28, reducing holdings by 24.1%.

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. The stock has gained 5.5% over 30 days and 15.0% over 90 days from the sale date, consistent with his historical pattern.
