Pomerantz Law Firm Investigates Trinseo PLC

On October 18, 2025, the Pomerantz Law Firm announced it is initiating an investigation related to claims made by investors of Trinseo PLC (NYSE: TSE). The inquiry focuses on whether Trinseo and its executives may have engaged in unlawful activities such as securities fraud and other suspicious business practices. Investors concerned about their rights and potential claims are strongly encouraged to reach out to Danielle Peyton at [email protected] or call 646-581-9980, ext. 7980 for further assistance.

Context of the Investigation

The investigation arises on the back of troubling announcements made by Trinseo earlier in the month. On October 6, 2025, the company informed investors that it would suspend its quarterly dividend indefinitely. Additionally, it disclosed the permanent closure of its manufacturing facilities in Rho, Italy (methyl methacrylate production) and Porto Marghera, Italy (acetone cyanohydrin production). These drastic measures are part of Trinseo’s strategic plan aimed at optimizing their operations, enhancing cash flow generation, and securing better long-term profitability. However, this decision raised considerable alarms among investors and analysts about the company’s financial health and viability.

Following the announcement, Trinseo’s stock price took a significant hit, plummeting by $0.29 (a decline of 12.21%), closing at $2.05 per share on October 7, 2025. Such fluctuations can induce serious concern about the integrity of the operations and communication coming from the company.
