Industry Context

This Form 4 filing reflects a standard practice in corporate governance where directors and executives receive equity-based compensation, such as Restricted Stock Units (RSUs), to incentivize long-term performance and align their interests with shareholders. Such grants are common across various industries, including the specialty materials sector where Trinseo PLC operates.

Comparison to Industry Standards

• The use of Restricted Stock Units (RSUs) as a form of director compensation is a widely adopted practice across public companies, consistent with global benchmarks for executive and board remuneration.

Stakeholder Impact

• Shareholders: The grant aligns the director's interests with shareholders, potentially fostering long-term value creation. There is a minor potential for future dilution upon vesting, which is typically factored into compensation plans.
• Employees: No direct impact mentioned, but such compensation practices can influence overall company culture regarding equity incentives.
