Appointment of Carol Flaton and Jill Frizzley to the Board

On January 16, 2026, the Board of Directors (the “Board”) of Trinseo PLC (the “Company”) voted to increase the size of the Board to eleven members. The Board also voted to fill the vacancies created by the increase to the size of the Board by appointing two new independent directors, Carol Flaton and Jill Frizzley, to the Board, effective immediately. The Board determined that Ms. Flaton and Ms. Frizzley are independent directors in accordance with applicable New York Stock Exchange listing requirements and rules.

In connection with the Company’s ongoing discussions with its financial stakeholders regarding its capital structure, the Board believes that Ms. Flaton and Ms. Frizzley will bring valuable expertise to the Board. Ms. Flaton has over 30 years of experience in banking & finance, transformation & restructuring, and governance & risk management.

In connection with their appointments to the Board, on January 12, 2026, Ms. Flaton and Ms. Frizzley each entered into an amendment to an existing consulting agreement with the Company (as amended, the “Agreements”) that contemplates payment of a $50,000 monthly fee for their service on the Board, among other things. In light of this monthly fee, the Board suspended the application of the Company’s standard director compensation program to Ms. Flaton and Ms. Frizzley.

Further, under the terms of the Agreements, Ms. Flaton and Ms. Frizzley are subject to the terms of the Company’s standard form of indemnification agreement, which is filed as Exhibit 10.1 to the Company’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission for the quarter ended on September 30, 2021, and which is incorporated by reference herein.
