  Trinseo PLC received written notice from the New York Stock Exchange (NYSE) that it determined to commence proceedings to delist the company's ordinary shares.

• Immediate Trading Suspension

  Trading in the company's ordinary shares on the NYSE has been suspended immediately as of March 2, 2026.

• Reason for Delisting

  The delisting is due to the company's failure to maintain an average market capitalization of at least $15 million over a 30-trading day period, violating NYSE listing standards.

• Impact on Trading and Shareholders

  Shares may move to the OTC Pink Limited Market, but liquidity and trading volume are uncertain. Transfers will be subject to Irish stamp duty, and DTC will cease clearing trades, complicating future share transfers.

This 8-K announces the definitive delisting of Trinseo PLC's ordinary shares from the New York Stock Exchange, a critical event for shareholders. While the company previously disclosed non-compliance with NYSE listing standards in a December 12, 2025 filing, this current filing confirms the NYSE's decision to commence delisting proceedings and, more importantly, the immediate suspension of trading. The move to a substantially more limited market, such as the OTC Pink, will severely impact liquidity and investor visibility. Furthermore, the application of Irish stamp duty and the cessation of clearing by Depository Trust Company (DTC) will complicate future share transfers and trading for existing shareholders.
