Law Offices of Howard G. Smith announces that a class action lawsuit has been filed on behalf of investors who purchased Trinseo PLC (“Trinseo” or the “Company”) (NYSE: TSE) securities between May 3, 2021 and March 27, 2023, inclusive (the “Class Period”). Trinseo investors have until June 20, 2023 to file a lead plaintiff motion.

Investors suffering losses on their Trinseo investments are encouraged to contact the Law Offices of Howard G. Smith to discuss their legal rights in this class action at 888-638-4847 or by email to howardsmith@howardsmithlaw.com.

On March 27, 2023, The Philadelphia Inquirer reported that Trinseo’s chemical plant in Bristol, Pennsylvania, which caused a toxic spill that threatened Philadelphia’s drinking water, has “a long history of mishaps – including at least four recent contamination incidents.”

On this news, Trinseo’s stock price fell $1.09, or 5.3%, to close at $19.62 per share on March 27, 2023, thereby injuring investors.

The complaint filed in this class action alleges that throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, and prospects. Specifically, Defendants failed to disclose to investors that: (1) the Company’s Bristol, Pennsylvania plant had a troubled safety record while under prior ownership and continued to be unsafe after the Company acquired it; (2) Defendants did not sufficiently disclose specific risks related to conducting operations at that plant; (3) Operating a chemical plant with an unsafe history and presently unsafe operations exposed the Company to a heightened risk of a chemical spill or other adverse event; and (4) as a result, Defendants’ positive statements about the Company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis at all relevant times.

If you purchased Trinseo securities, have information or would like to learn more about these claims, or have any questions concerning this announcement or your rights or interests with respect to these matters, please contact Howard G. Smith, Esquire, of Law Offices of Howard G.
