Director Farrell Matthew purchases 100,000 shares at blended avg $2.40 over 3 days; stock down -64.2% from 52-week high

Matthew Farrell executed 3 separate purchases totaling 100,000 shares for $240,027.82 over three consecutive trading days (August 12–14, 2025), raising his holding from 150,225 shares to 250,225 shares—a 66.6% increase in position size. The stock is currently trading at $2.43, down -64.2% from its 52-week high of $6.79 and off -14.4% over the past 30 days. At the same ticker, Farrell's sole prior buy (December 2023) posted a -27.9% return over 90 days, and his cross-ticker buy history shows 0 of 1 prior buys well-timed at the 90-day mark. The company is unprofitable—posting a net loss of $105,500,000 on revenue of $784,300,000 in the latest quarter—and faces declining revenues year-over-year (-4.4%). The scale and timing of this accumulation against a depressed price backdrop, combined with Farrell's unsuccessful prior buy at this same ticker and the company's negative earnings profile, merits investor scrutiny of the rationale behind this substantial position increase.

VP Frisch purchases 3,800 shares of unprofitable Trinseo at $4.13 blended average, growing stake +26.6%; company burning cash with $-87.3M net income.

Johanna Frisch, VP and Treasurer of Trinseo PLC, executed 3 separate purchases totaling 3,800 shares for $15,708.00 across three consecutive trading days (2025-03-12 to 2025-03-14), raising her holdings from 14,292 shares to 18,092 shares (+26.6%). The blended average price of $4.13 represents recent trading activity while the stock trades at $4.27 currently and stands 37.1% below its 52-week high of $6.79. The company context is deeply concerning: Trinseo is unprofitable with a full-year net income of $-87,300,000.00 and revenue declining -4.4% year-over-year, yet its Treasurer is accumulating shares. The timing occurs as the stock has fallen 10.5% over 30 days and 22.5% over 90 days, suggesting the insider is purchasing into a deteriorating price environment while the company faces fundamental earnings headwinds.

Director Jeffrey Cote buys 150,600 shares in 2 tranches for $452,534 as Trinseo stock rebounds 27.6% in 30 days from 52-week low.

Jeffrey Cote, a director at Trinseo PLC, purchased 150,600 shares across 2 transactions at an average price of $3.00, coinciding with a significant near-term rally: the stock is up 27.6% over the past 30 days and currently trades at $3.37. This represents his first shareholding after zero prior position. The timing is notable given the company's weak fundamentals: Trinseo reported a net loss of $-67.8M in its latest quarter, full-year net income was negative, and annual revenue declined 26.0% year-over-year. The company's market cap of $119.1M reflects deep distress relative to quarterly revenue of $920.0M. Cote's entry onto the share registry during a recovery phase—while the stock remains 71.7% below its 52-week high—occurs alongside a cluster of 2 other insider purchases within the past 14 days, suggesting coordinated director engagement during a period of operational and financial pressure.

SVP/CLO Angelo Chaclas bought 75,000 TSE shares at $2.57; stock down 81.2% from 52-week high of $14.33, co. posted $67.8M loss.

Chaclas purchased 75,000 shares at $2.57 on 2024-08-12, increasing his holdings by 56.8% to 207.0K shares. The purchase occurs amid significant headwinds: Trinseo is trading -81.2% from its 52-week high of $14.33, the company reported a net loss of $67.8M on $920.0M quarterly revenue with annual revenue declining 26.0%, and the stock has fallen 21.0% over the prior 90 days. His prior buy at this ticker on 2023-09-12 returned -19.7% over 90 days and has a 0.00% cross-ticker win rate. The timing and scale of this purchase against deteriorating fundamentals and persistent share-price weakness merit observation of whether this reflects material information unavailable to public markets or execution of a scheduled trading plan.

CEO Frank A. Bozich buys 40,000 TSE shares at $2.57; stock now -81.2% from 52-week high amid -26.0% revenue decline and unprofitability.

CEO Frank A. Bozich purchased 40,000 shares at $2.57 on 2024-08-12, increasing his holdings by 9.5% to 462.2K shares. The purchase occurs in a severely distressed context: the stock trades at $2.70 currently, down 81.2% from its 52-week high of $14.33, while the company reported a -26.0% annual revenue decline and a negative full-year net income of $-67.8M on $920.0M quarterly revenue. Critically, Bozich's cross-ticker buy history reveals a 0.00% win rate over 90-day periods with an average 90-day return of -19.7%. His prior buy at this same ticker on 2023-09-12 also posted negative returns at both 30-day and 90-day marks. This purchase adds to the negative data pattern rather than signaling improved conviction in the company's prospects.
