As previously disclosed on Form 8-K dated April 15, 2020, Trinseo S.A. (the "Company") announced that two directors, Stephen M. Zide and Christopher D.

As previously disclosed in the Company's proxy statement filed April 27, 2020, both Messrs. Zide and Pappas notified the Board of their decision not to stand for reelection in 2021 and to retire from the Board once uncertainty related to the global pandemic had diminished and suitable Board candidates had been identified. On September 24, 2020, Mr. Zide and Mr. Pappas notified the Company that they intend to retire from the Board effective September 30, 2020. The decision by Mr. Zide and Mr. Pappas to retire as directors of the Company was not the result of any disagreement with the Company on any matter relating to the operations, internal controls, policies or practices of the Company.

There is no arrangement or understanding between Ms. Desmond or Mr. Farrell and any other person pursuant to which either was elected to serve as a director of the Company. The Company is not aware of any transactions involving Ms. Desmond or Mr. Farrell that are reportable under Item 404(a) of Regulation S-K.
​
Ms. Desmond will be appointed to the Compensation & Talent Development Committee and the Audit Committee, and Mr. Farrell will be appointed to the Nominating & Corporate Governance Committee and the Compensation & Talent Development Committee of the Board.
​
For their service as non-employee directors, Mr. Farrell and Ms. Desmond will be entitled to receive compensation in accordance with the Company's standard compensation arrangements for non-employee directors, which are described under the heading "Director Compensation" in the Company's definitive proxy statement on Schedule 14A filed with the Securities and Exchange Commission on April 27, 2020.
