Costa Mark J

Director Costa bought 25 shares net-sold 5 across 4 transactions Mar–Oct 2023; stock down 14.8% from high.

Costa Mark J executed 2 purchases totaling 25 for $2,056.90 and 2 sales totaling 30 for $2,153.00 across the filing period, resulting in a net reduction of 5 shares (-1.1% vs pre-transaction holdings of 468 shares). The transaction prices ($84.27, $77.49, $80.95, $66.05) show declining momentum, with the final sale at $66.05 occurring as the stock continued to deteriorate; current price is $70.71, down 14.8% from the 52-week high of $83.00. His cross-ticker track record across 5 prior sells shows an 80.00% well-timed rate with avg 90d return -2.5%, but this same-ticker activity represents routine director holdings management rather than a concentrated bet. IFF reported a full-year net loss and annual revenue decline of -5.2%, and a cluster pattern shows 2 other insiders also bought within 14 days—a potential alignment signal during the stock's weakness.

CEO Costa Mark J bought 7,400 shares of EMN at $67.89 on 2025-08-27 (total $502.4K); stock down 40.1% from 52-week high, cluster of 10 other insiders bought within 14 days.

CEO Costa Mark J purchased 7,400 shares at $67.89, increasing his holdings by 1.7% to 453.986 shares, amid a broader cluster pattern where 10 other insiders also bought within the past 14 days. The purchase occurs with EMN trading at $68.18 current price, down 40.1% from its 52-week high of $113.77 and down 10.0% over the past 30 days and 13.0% over 90 days. Historically, Costa's prior trades at EMN show a pattern of 4 of 5 sells that were well-timed at the 90-day mark, with negative 90-day returns on those sells, suggesting sound sell discipline; however, his cross-ticker buy track record shows 0.00% 90-day win rate (both prior buys were underwater by 90 days), while his cross-ticker sells demonstrated 71.43% well-timed rate. The coordinated buying activity among multiple insiders at a depressed price level offers a different signal than this individual's historical buy performance, warranting assessment of whether the broader team sees current valuation as attractive relative to fundamentals (P/E 9.40, $2.3B revenue, $140.0M net income).

CEO Costa sold 18,278 shares of EMN at $105.00 on 2024-11-29 for $1,919,190.00; post-transaction holdings 395,699 shares.

Costa Mark J, CEO & Board Chair, executed an open-market sale of 18,278 shares at $105.00, reducing his holdings by 4.4% to 395,699 shares. The transaction occurred as EMN trades at $102.94, down 9.5% from its 52-week high of $113.77, and follows two prior sales at the same ticker on 2024-11-26 (outcomes not yet measurable). His cross-ticker track record shows 6 prior sells with a 50.00% well-timed rate at the 90-day mark, while his prior trades at EMN are mixed: the most recent measurable sale on 2024-05-07 produced a -6.5% 90-day return (well-timed), but a 2024-03-01 sale generated +15.1% at 90 days (poorly timed). Annual revenue growth stands at -13.0%, signaling business headwinds that warrant investor attention to the fundamental context of this liquidation.

The sales were priced at $105.63 and $105.01, both above the current price of $104.23. His track record at EMN shows mixed outcomes: a May 2024 sale preceded a 90-day decline (-6.5%), while a March 2024 sale preceded a 90-day gain (+15.1%), indicating 1 of 2 prior EMN sales were well-timed by the 90-day measure. In the broader cross-ticker context, his prior 4 open-market sales averaged 50% well-timed at the 90-day mark, with an average 90-day return of +3.6%.
