What is this Case About: Trinseo PLC (TSE) Failed to Disclose the Multitude of Problems at its Bristol, PA Plant

According to the complaint, defendants failed to disclose 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; and (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.

On March 26, 2023, the Company published an announcement on its website that stated, in pertinent part: “Altuglas, a subsidiary of Trinseo, is working with local, state and federal agencies to clean up the release of a latex emulsion product from its manufacturing facility in Bristol, PA. The release, which occurred Friday evening, March 24, appears to be the result of an equipment failure." The next day, The Philadelphia Inquirer released an article entitled “Bristol plant that spilled chemicals into Philly’s water supply had other mishaps over the last decade,” highlighting the decade-long problems at the plant. On this news, Trinseo’s stock fell $1.09 per share on March 27, 2023, or 5.2%, damaging investors.
