Dear André,  

We would like to summarize the mutually agreed to details concerning your resignation and separation from Trinseo Europe GmbH on 31 January 2024, unless otherwise adjusted as described below.

Termination Date, Release from Obligation to Work and Permission to Take New Employment

We confirm that your employment with Trinseo Europe GmbH will terminate on 31 January 2024 (“End Employment Date”). Except as provide for herein, all your duties and rights according to your employment contract shall remain in force until this date. However, if you find a new employment position prior to 31 January 2024, you may, by giving us at least one week advance written notice, terminate your employment with the Company with effect as of this earlier new employment start date ("New Employment Start Date") where the New Employment Start Date shall become your End Employment Date. The LTI disposition will be adjusted accordingly and the amount of the Severance described below will be increased by any reduction in Garden Leave associated with your New Employment Start Date.

Trinseo is releasing you from your day-to-day work responsibilities (“Garden Leave”) effective as of 1 August 2023 (“Release Date”) under the condition of a successful handover.  Effective as of today until your Release Date, you will serve as Special Advisor to the CEO and Executive Leadership Team.  All remaining and unused paid vacation that currently have accrued or may accrue in the future shall be deemed taken before your End Employment Date.

As of 17 July 2023, the Company requires that you transition to a permanent home office arrangement and give up your Pfäffikon office.  

Expenses

All outstanding claims for expenses reasonably and properly incurred in the performance of your duties will be submitted and properly reimbursed by the Company in ordinary course assuming you will hand over any related receipts by 4 September 2023 the latest.

Severance

Provided you provide the Company no later than 2 February 2024 and no earlier than the End Employment Date with the attached general release that you have duly signed; you will be paid CHF 1,169,280 gross that is equal to one and one-half (1.5) multiplied by the sum of your current annual Base Salary (CHF487,200) and Target Bonus (60%) for the year of termination minus the amount of base salary received during the Garden Leave period (i.e. the amount of six months salary which is CHF 243,600).  The gross amount of CHF 925,680 (CHF 1,169,280 minus CHF 243,600) will be paid in equal monthly installments for a period of eighteen (18) months following the End Employment Date.

Performance Award (PA) & Merit Increase

You will be paid a full portion of Performance Award for 2023 based on the Company’s actual performance for discretionary executive payouts as determined by the Board and with your Individual Goal Achievement set to 90%.  Your 2023 Peformance Award payment will take place in accordance with the ordinary bonus payment cycle of the Company in March 2024.

You will not receive a merit increase for 2024 and will not receive a 2024 Performance Award payment.

Long Term Incentive (LTI) Awards

Any outstanding unvested LTI awards shall continue to vest under the 2014 Omnibus Incentive Plan (including any associated acceptance agreements) through the End Employment Date.  Any outstanding unvested RSU awards granted before 2022 that remain unvested as of the End Employment Date will be handled under the 2014 Omnibus Incentive Plan and shall be given restructuring prorata treatment. Any outstanding unvested RSU awards granted after 2022 that remain unvested as of the End Employment Date will be handled under the 2014 Omnibus Incentive Plan and shall be given restructuring treatment. Any outstanding unvested PSU awards that remain unvested as of the End Employment Date will be handled under the 2014 Omnibus Incentive Plan and shall be forfeited.  Unvested Stock Options will continue to vest according to the normal vesting schedule and any vested Stock Options remain intact and exercisable.  The exercise periods associated with the Stock Options may be adjusted, as defined in accordance with the rules of the 2014 Omnibus Incentive Plan.

You will not receive an LTI award in 2024.

Attached please find an LTI Attachment which provides further details.

Outplacement Support

Upon request, the Company will grant you outplacement support which will be provided through a defined consultant selected by the Company. There will be no payment in lieu.

Reference Letter

At your request, Trinseo Europe GmbH will provide you with an interim reference letter within 20 days from your return of this agreement (including all required other documents) duly signed and with a final reference letter within 10 days from commencing Garden Leave or the End Employment Date, at your choice.

Obligatory Accident Insurance

On the 31^st day after the day on which your entitlement to at least half of the salary ceases, the obligatory insurance for accidents during work time as well as accidents during leisure time expires. Unless you are insured against accidents with a new contract of employment within this 31 day period of time, you will be required to insure accident coverage from your personal sickness insurance fund. Another option would be to sign up for a voluntary accident insurance (Abredeversicherung) through our insurance SUVA. The necessary document can be downloaded from the homepage of SUVA.

Handover and Return of Employer’s Belongings / Officer & Director Resignations

Others & SEC 8K Filing

You agree to sign a secrecy agreement and return it to the Human Resources department along with the general release referenced above.

Being on the New York Stock Exchange, Trinseo PLC is subject to the United States Securities And Exchange Commission (“SEC”) laws and regulations.  Due to your status as a Named Executive Officer and your separation from the Company, this event and agreement are publically reportable on SEC Form 8-K.  Your separation will be reported on SEC Form 8-K no later than 20 July 2023.

We believe the above covers all of the discussed points and we wish you well in your future endeavors.

Terms used herein but not otherwise defined shall have the meanings given to them in the Agreement.

I understand that the severance, outplacement and other benefits paid or granted to me, and any other accomodations received, under the Agreement represent, in part, consideration for signing this General Release and are not salary, wages or benefits to which I was already entitled.

Such payments and benefits will not be considered compensation for purposes of any employee benefit plan, program, policy or arrangement maintained or hereafter established by the Company or its affiliates.

I agree that this General Release does not waive or release any rights or claims that I may have which arise after the date I execute this General Release.

Trinseo Announces Executive Leadership Team Changes

- Trinseo is restructuring its Executive Leadership Team (ELT) in a move specifically designed to create a more streamlined organizational structure that will help drive improved performance, value creation, and delivery of Trinseo’s transformation strategy. As a result, the ELT will reduce in size from twelve to nine members.

July 18, 2023

Trinseo (NYSE: TSE), a specialty material solutions provider, today announced a restructuring of its Executive Leadership Team (ELT) to accelerate the Company’s continued transformation as a provider of more sustainable, highly engineered, specialty materials and solutions. This new structure is focused on creating an environment that will further enable and enhance the Company’s strategic focus on strengthening transformative innovation, customer-centric solutions and increased sustainability across all its products and businesses.

The restructuring will include the departure of three members of the Executive Leadership Team and a corresponding reassignment of responsibilities for three existing members of the ELT. Francesca Reverberi, currently Senior Vice President, Chief Sustainability Officer, will take on added responsibilities as head of Engineered Materials, a position she has held previously in the organization.

Bregje (“Bee”) Roseboom-Van Kessel, whose previous role was as Senior Vice President, Plastic Solutions, will assume leadership of the combined Plastics Solutions and Polystyrene & Feedstocks business. James Ni, currently Senior Vice President, Latex Binders, will assume ownership for marketing and commercial excellence across Trinseo. Combined, these three individuals bring almost six decades of functional leadership experience and industry knowledge to the organization.

“Like so many in the chemicals industry, we continue to face unprecedented macroeconomic challenges, but we remain intensely focused on doing what we believe is necessary to help us continue our transformation journey so that we emerge even stronger when this unusual cycle ends. Irrespective of the current environment, these changes are absolutely aligned with our Company’s mission to strategically reinvent our organization and the products we provide our customers through bold, breakthrough innovation,” said CEO Frank Bozich. “Given their depth of knowledge and experience, with Francesca, “Bee” and James, we are in an excellent position to realize this mission and I have every confidence in their leadership,” added Bozich.

André Lanning, who previously held the position of Chief Commercial Officer will be leaving the organization to pursue other opportunities, as will Nicolas Joly, SVP, Polystyrene & Feedstocks and Jean-Luc Béal who held the position of SVP, Engineered Materials. After a short transition period, these changes will be effective August 1, 2023.

“I want to thank André, Nicolas and Jean-Luc for their leadership and commitment to excellence, and we will continue to build on their efforts to help move our organization forward,” said CEO Bozich.
