According to the Complaint, Trinseo PLC purports to be a “specialty material solutions provider with a focus on partnering with companies to bring ideas to life in an imaginative, smart, and sustainability-focused manner."

The Complaint alleges that Defendants throughout the Class Period made false and/or misleading statements and/or failed to disclose, among other things, 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’ statements about its business, operations, and prospects, were materially false and misleading and/or lacked a reasonable basis at all times.

On August 8, 2023, the Court issued an Order appointing Lead Plaintiff and Counsel. Lead Plaintiff voluntarily dismissed the case on October 19.
