For the quarterly period ended March 31, 2023

Unless otherwise indicated or required by context, as used in this Quarterly Report on Form 10-Q (“Quarterly Report”), the term “Trinseo” refers to Trinseo PLC (NYSE: TSE), a public limited company existing under the laws of Ireland, and not its subsidiaries. The terms “Company,” “we,” “us” and “our” refer to Trinseo and its consolidated subsidiaries, taken as a consolidated entity. Trinseo PLC is the surviving entity of a cross-border merger with our predecessor company, Trinseo S.A., which merger was completed in October 2021. All financial data provided in this Quarterly Report is the financial data of Trinseo PLC, unless otherwise indicated. Prior to the formation of the Company, our business was wholly owned by The Dow Chemical Company (together with other affiliates, “Dow”). The Company may distribute cash to shareholders under Irish law via dividends or distributions made out of distributable profits.

Definitions of capitalized terms not defined herein appear within our Annual Report on Form 10-K for the year ended December 31, 2022 (“Annual Report”) filed with the Securities and Exchange Commission (“SEC”) on February 27, 2023.

Cautionary Note on Forward-Looking Statements

This Quarterly Report contains, without limitation, statements concerning plans, objectives, goals, projections, forecasts, strategies, future events or performance, and underlying assumptions and other statements, which are not statements of historical facts. Forward-looking statements may be identified by the use of words like “expect,” “anticipate,” “believe,” “intend,” “forecast,” ”estimate,” “see,” “outlook,” “will,” “may,” “might,” “potential,” “likely,” “target,” “plan,” “contemplate,” “seek,” “attempt,” “should,” “could,” “would,” or expressions of similar meaning. Forward-looking statements reflect management’s evaluation of information currently available and are based on our current expectations and assumptions regarding our business, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict.

Specific factors that may cause future results to differ from those expressed by the forward-looking statements, or otherwise impact performance or other predictions of future actions have, in many but not all cases, been identified in connection with specific forward-looking statements. Factors that might cause such a difference include, but are not limited to, our ability to successfully execute our transformation strategy and business strategy; increased costs or disruption in the supply of raw materials; increased energy costs; our ability to successfully generate cost savings and increase profitability through asset restructuring initiatives; compliance with laws and regulations impacting our business; conditions in the global economy and capital markets; our ability to successfully investigate and remediate chemical releases on or from our sites, make related capital expenditures, reimburse third-party cleanup costs or settle potential regulatory penalties or other claims; and those discussed in our Annual Report filed with the SEC on February 27, 2023 under Part I, Item IA— “Risk Factors,” within this Quarterly Report and in other filings and furnishings made by the Company with the SEC from time to time.

As a result of these or other factors, our actual results, performance or achievements may differ materially from those contemplated by the forward-looking statements. They are neither statements of historical fact nor guarantees or assurances of future performance. Therefore, we caution you against relying on these forward-looking statements. The forward-looking statements included in this Quarterly Report are made only as of the date hereof. We undertake no obligation to publicly update or revise any forward-looking statement as a result of new information, future events or otherwise, except as otherwise required by law.

Notes to Condensed Consolidated Financial Statements

(Dollars in millions, unless otherwise stated)

(Unaudited)

NOTE 1—BASIS OF PRESENTATION

The unaudited interim condensed consolidated financial statements of Trinseo PLC and its subsidiaries (the “Company”) as of and for the periods ended March 31, 2023 and 2022 were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and reflect all adjustments, consisting only of normal recurring adjustments, which, in the opinion of management, are considered necessary for the fair statement of the results for the periods presented. Because they cover interim periods, the statements and related notes to the financial statements do not include all disclosures normally provided in annual financial statements, and therefore, these statements should be read in conjunction with the 2022 audited consolidated financial statements included within the Company’s Annual Report on Form 10-K (“Annual Report”) filed with the Securities and Exchange Commission (“SEC”) on February 27, 2023. The Company’s condensed consolidated financial statements presented herein reflect the latest estimates and assumptions made by management that affect the reported amounts and related disclosures as of and for the period ended March 31, 2023. However, actual results could differ from these estimates and assumptions.

The December 31, 2022 condensed consolidated balance sheet data presented herein was derived from the Company’s December 31, 2022 audited consolidated financial statements, but does not include all disclosures required by GAAP for annual periods.

Throughout this Quarterly Report, unless otherwise indicated, amounts and activity are presented on a continuing operations basis.

NOTE 2—RECENT ACCOUNTING GUIDANCE

As of March 31, 2023, there was no recently issued accounting standards which would have a material effect on the Company’s condensed consolidated financial statements.

NOTE 3—ACQUISITIONS

Acquisition of Heathland B.V.

On January 3, 2022, the Company completed the acquisition of Heathland B.V. (“Heathland”) from Heathland Holding B.V. (“Heathland Holding”), through the purchase of all issued and outstanding shares (the “Heathland Acquisition”). Heathland is a leading collector and recycler of post-consumer and post-industrial plastic wastes in Europe. The total purchase price consideration is estimated to be $29.3 million, including an initial cash purchase price of $22.9 million which was paid during the three months ended March 31, 2022, as well as $6.4 million of contingent cash consideration, representing the fair value of certain earn-out payments. The maximum amount of potential earn-out payments is $6.8 million, which will become payable to Heathland Holding as and when the related performance milestones or thresholds are achieved over the three-year period following the date of acquisition. Heathland results are included within the Plastics Solution segment. The Company allocated the purchase price of the acquisition to identifiable assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. Refer to the Annual Report for further information.

In February 2023, the Company delivered the first year earn-out to Heathland Holding based on its first related performance milestones or threshold in the amount of $1.2 million.

NOTE 4—DIVESTITURES AND DISCONTINUED OPERATIONS

On December 1, 2021, the Company completed the divestiture of its Synthetic Rubber business to Synthos S.A. and certain of its subsidiaries (together, “Synthos”) for a purchase price of $402.4 million, which reflected a reduction of approximately $41.6 million for the assumption of pension liabilities by Synthos and $47.0 million for net working capital (excluding inventory) retained by Trinseo. Refer to the Annual Report for further information. At closing, the Company and Synthos executed a long-term supply agreement, in which Trinseo will supply Synthos certain raw materials used in the Synthetic Rubber business subsequent to the sale.

The results of Americas Styrenics are included within its own reporting segment.

This amount represents the difference between the book value of assets held by the joint venture and the Company’s 50% share of the total recorded value of the joint venture’s assets, inclusive of certain adjustments to conform with the Company’s accounting policies. This difference is being amortized over a weighted average remaining useful life of approximately 1.8 years as of March 31, 2023.

Total long-term debt, net of unamortized deferred financing fees							$	2,299.9					$	2,301.6

(1) This caption does not include deferred financing fees related to the Company’s revolving facilities, which are included within “Deferred charges and other assets” on the condensed consolidated balance sheets.

(2) As of March 31, 2023, under the 2026 Revolving Facility, the Company had a capacity of $375.0 million and $22.0 million outstanding letters of credit. As of March 31, 2023, the Company had funds available for borrowing of $100.5 million (net of the applicable $12.0 million outstanding letters of credit as defined in the secured credit agreement), which reflects the borrowing limit imposed by the springing covenant. The springing covenant applies when 30% or more of the 2026 Revolving Facility’s capacity is drawn which then requires the Company to meet a first lien net leverage ratio (as defined in the secured credit agreement) not to exceed 3.50x at the end of each financial quarter. As of March 31, 2023, the first lien net leverage ratio was 4.85x and the outstanding borrowings did not exceed the 30% threshold. Additionally, the Company is required to pay a quarterly commitment fee in respect of any unused commitments under this facility equal to 0.375% per annum.

(3) As of March 31, 2023, this facility had a borrowing capacity of $150.0 million, and the Company had approximately $150.0 million of accounts receivable available to support this facility, based on the pool of eligible accounts receivable.

(4) The current portion of long-term debt was primarily related to $14.5 million of the scheduled future principal payments on both the 2024 Term Loan B and 2028 Term Loan B as of March 31, 2023 and December 31, 2022.

NOTE 9—GOODWILL

The following table shows changes in the carrying amount of goodwill, by segment, from December 31, 2022 to March 31, 2023:

	Engineered		Latex		Plastics						Americas
	Materials		Binders		Solutions		Polystyrene		Feedstocks		Styrenics		Total
Balance at December 31, 2022	$	348.9	$	14.8	$	42.5	$	4.2	$	—	$	—	$	410.4
Foreign currency impact		2.6		0.3		0.8		0.1		—		—		3.8
Balance at March 31, 2023	$	351.5	$	15.1	$	43.3	$	4.3	$	—	$	—	$	414.2

As a result of the Company’s fourth quarter 2022 impairment testing, an impairment charge was taken for the PMMA business and Aristech Surfaces reporting units primarily due to the continuation of the challenging macroeconomic environment experienced in 2022 into the fourth quarter of 2022, including significantly lower demand

12

for building & construction and wellness applications, which led to lower operating results including slower growth projections, and a prolonged drop in market capitalization, as well as an increase in the weighted average cost of capital. This goodwill may be at risk for future impairment due to the remaining fair value being equal to carrying value as a result of the recorded impairment. While the challenging macroeconomic environment has continued to impact these businesses in the first quarter of 2023, the Company performed qualitative analyses over this goodwill, including consideration of current and estimated future financial results of the related businesses, general and industry-specific economic conditions, changes in reporting unit carrying values and potential changes to the assumptions used in the previous fair value calculations. Based on these analyses, the Company has not identified any triggering events since the fourth quarter of 2022 impairment test indicating that is more likely than not that goodwill is impaired. Should these conditions persist, or other events occur indicating that the estimated future cash flows of these businesses have declined, the Company may be required to record future non-cash impairment charges related to goodwill.

As of March 31, 2023 and December 31, 2022, the reported balance of goodwill included accumulated impairment losses of $297.1 million in the Engineered Materials segment.

NOTE 10—DERIVATIVE INSTRUMENTS

The Company’s ongoing business operations expose it to various risks, including fluctuating foreign exchange rates, interest rate risk, and commodity price risk, in particular natural gas. To manage these risks, the Company periodically enters into derivative financial instruments, such as foreign exchange forward contracts, interest rate swap agreements, and commodity swaps agreements, forward contracts, or options. The Company does not hold or enter into financial instruments for trading or speculative purposes. All derivatives are recorded on the condensed consolidated balance sheets at fair value.

Foreign Exchange Forward Contracts

Certain subsidiaries have assets and liabilities denominated in currencies other than their respective functional currencies, which creates foreign exchange risk. The Company’s principal strategy in managing its exposure to changes in foreign currency exchange rates is to naturally hedge the foreign currency-denominated liabilities on its balance sheet against corresponding assets of the same currency, such that any changes in liabilities due to fluctuations in exchange rates are offset by changes in their corresponding foreign currency assets. In order to further reduce this exposure, the Company also uses foreign exchange forward contracts to economically hedge the impact of the variability in exchange rates on assets and liabilities denominated in certain foreign currencies. These derivative contracts are not designated for hedge accounting treatment.

As of March 31, 2023, the Company had open foreign exchange forward contracts with a notional U.S. dollar equivalent absolute value of $657.5 million. The following table displays the notional amounts of the most significant net foreign exchange hedge positions outstanding as of March 31, 2023:

	March 31,
Buy / (Sell)	2023
Euro	$	(520.9)
Chinese Yuan	$	(48.4)
South Korean Won	$	(21.8)
Swiss Franc	$	(19.6)
Swedish Krona	$	14.7

Open foreign exchange forward contracts as of March 31, 2023 had maturities occurring over a period of two months.

Foreign Exchange Cash Flow Hedges

The Company also enters into forward contracts, as deemed appropriate, with the objective of managing the currency risk associated with forecasted U.S. dollar-denominated raw materials purchases by one of its subsidiaries whose functional currency is the euro. By entering into these forward contracts, which are designated as cash flow

13

hedges, the Company buys a designated amount of U.S. dollars and sells euros at the prevailing market rate to mitigate the risk associated with the fluctuations in the euro-to-U.S. dollar foreign currency exchange rates. The qualifying hedge contracts are marked-to-market at each reporting date and any unrealized gains or losses are included in Accumulated Other Comprehensive Income (“AOCI”) to the extent effective, and reclassified to cost of sales in the period during which the transaction affects earnings or it becomes probable that the forecasted transaction will not occur.

The Company had no open foreign exchange cash flow hedges as of March 31, 2023.

Commodity Cash Flow Hedges & Commodity Economic Hedges

The Company purchases certain commodities, primarily natural gas, to operate facilities and generate heat and steam for various manufacturing processes, which purchases are subject to price volatility. In order to manage the risk of price fluctuations associated with these commodity purchases, as deemed appropriate, the Company may enter into commodity swaps, forward contracts, or options. As of March 31, 2023, the Company had open commodity swap agreements, which effectively convert a portion of its natural gas costs into a fixed rate obligation. These commodity derivatives are designated as cash flow hedges, and as such, the contracts are marked-to-market at each reporting date and any unrealized gains or losses are included in AOCI to the extent effective, and reclassified to cost of sales in the period during which the transaction affects earnings or it becomes probable that the forecasted transaction will not occur.

Open commodity cash flow hedges as of March 31, 2023 had maturities occurring over a period of 21 months and had a notional value of approximately 964 thousand megawatt hours of natural gas purchases.

The Company may also enter into certain commodity swap agreements to economically hedge the impact of these price fluctuations, which are not designated for hedge accounting treatment. Open commodity economic hedges as of March 31, 2023 had maturities occurring over a period of 24 months and had a notional value of approximately 895 thousand megawatt hours of natural gas purchases.

Interest Rate Swaps

On September 6, 2017, the Company issued the 2024 Term Loan B, which currently bears an interest rate of LIBOR plus 2.00%, subject to a 0.00% LIBOR floor. In order to reduce the variability in interest payments associated with the Company’s variable rate debt, during 2017 the Company entered into certain interest rate swap agreements to convert a portion of these variable rate borrowings into a fixed rate obligation. These interest rate swap agreements are designated as cash flow hedges, and as such, the contracts are marked-to-market at each reporting date and any unrealized gains or losses are included in AOCI to the extent effective, and reclassified to interest expense in the period during which the transaction affects earnings or it becomes probable that the forecasted transaction will not occur. Under the terms of the swap agreements, with a net notional U.S. dollar equivalent of $200.0 million and an effective date of September 29, 2017, the Company was required to pay the counterparties a stream of fixed interest payments at a rate of 1.81%, and in turn, receives variable interest payments based on 1-month LIBOR from the counterparties. These interest rate swap agreements matured in September 2022, and the Company has no remaining open interest rate swap agreements.

Net Investment Hedge

The Company accounts for its cross currency swaps (“CCS”) under the spot method, meaning that changes in the fair value of the hedge included in the assessment of effectiveness (changes due to spot foreign exchange rates) are recorded within AOCI, where they remain until either the sale or substantially complete liquidation of the subsidiary subject to the hedge. Additionally, the initial value of any component excluded from the assessment of effectiveness is recognized in income using a systematic and rational method over the life of the hedging instrument and any difference between the change in the fair value of the excluded component and amounts recognized in income under that systematic and rational method is recognized in AOCI. When applicable, the Company amortizes any initial excluded component value of a CCS as a reduction of “Interest expense, net” in the condensed consolidated statements of operations using the straight-line method over the remaining term of the related CCS. Additionally, interest receipts and payments are accrued under the terms of the Company’s CCS and are recognized within “Interest expense, net” in the condensed consolidated statements of operations.

The Company entered into a CCS arrangement (the “2017 CCS”) on September 1, 2017, swapping U.S. dollar principal and interest payments of $500.0 million at an interest rate of 5.375% on its 2025 Senior Notes for euro-denominated payments of €420.0 million at a weighted average interest rate of 3.45% for approximately five years. On

14

February 26, 2020, the Company settled its 2017 CCS and replaced it with a new CCS arrangement (the “2020 CCS”) that carried substantially the same terms as the 2017 CCS. Under the 2020 CCS, the Company notionally exchanged $500.0 million at an interest rate of 5.375% for €459.3 million at a weighted average interest rate of 3.672% for approximately 2.7 years, with a final maturity of November 3, 2022. The cash flows under the 2020 CCS are aligned with the Company’s principal and interest obligations on its 5.375% 2025 Senior Notes. Refer to the Annual Report for further information.

On April 7, 2022, the Company settled its existing 2020 CCS, which were set to mature in November 2022. Upon settlement of the 2020 CCS, the Company realized net cash proceeds of $1.9 million.

Forward contracts, interest rate swaps, commodity forward contracts, swaps, or options, and cross currency swaps are entered into with a limited number of counterparties, each of which allows for net settlement of all contracts through a single payment in a single currency in the event of a default on or termination of any one contract. As such, in accordance with the Company’s accounting policy, these derivative instruments are recorded on a net basis by counterparty within the condensed consolidated balance sheets.

Refer to Notes 11 and 18 of the condensed consolidated financial statements for further information regarding the fair value of the Company’s derivative instruments and the related changes in AOCI.

NOTE 11—FAIR VALUE MEASUREMENTS

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities measured at fair value are classified using the following hierarchy, which is based upon the transparency of inputs to the valuation as of the measurement date.

Level 1—Valuation is based upon quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2—Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

Level 3—Valuation is based upon other unobservable inputs that are significant to the fair value measurement.

The following table summarizes the basis used to measure certain assets and liabilities at fair value on a recurring basis in the condensed consolidated balance sheets as of March 31, 2023 and December 31, 2022:

	March 31, 2023
	Quoted Prices in Active Markets for Identical Items		Significant Other Observable Inputs		Significant Unobservable Inputs

Total fair value	$	—	$	(29.7)	$	—	$	(29.7)

The Company uses an income approach to value its derivative instruments, utilizing discounted cash flow techniques, considering the terms of the contract and observable market information available as of the reporting date, such as interest rate yield curves and currency spot and forward rates. Significant inputs to the valuation for these derivative instruments are obtained from broker quotations or from listed or over-the-counter market data, and are classified as Level 2 in the fair value hierarchy.

Nonrecurring Fair Value Measurements

The Company measured certain financial assets at fair value on a nonrecurring basis during the year ended December 31, 2022, which were still held as of March 31, 2023. These financial assets represent the Company’s styrene monomer assets in Boehlen, Germany, which it continued to operate until the fourth quarter of 2022 when the Company decided to close this plant in connection with the asset restructuring plan. Refer to Note 17 for further information. These assets were measured at fair value using underlying fixed asset records in conjunction with the use of industry experience and available market data, which are classified as Level 3 significant unobservable inputs in the fair value hierarchy. During the three months ended March 31, 2023, the Company recorded additional impairment charges of $0.3 million related to capital expenditures at the Boehlen styrene monomer facility that it determined to be impaired, which are also included within “Impairment and other charges” on the condensed consolidated statements of operations. Refer to the Company’s Annual Report for further information. As of March 31, 2023 and December 31, 2022, the value of the Boehlen styrene monomer assets are recorded at $3.2 million within the Company’s condensed consolidated balance sheets herein.

There were no other financial assets or liabilities measured at fair value on a nonrecurring basis as of December 31, 2022.

Fair Value of Debt Instruments

The following table presents the estimated fair value of the Company’s outstanding debt not carried at fair value as of March 31, 2023 and December 31, 2022:

	As of		As of
	March 31, 2023		December 31, 2022
2029 Senior Notes	$	269.1	$	292.3
2028 Term Loan B		662.1		687.1
2025 Senior Notes		406.8		416.9
2024 Term Loan B		653.8		645.6
Total fair value	$	1,991.8	$	2,041.9

The fair value of the Company’s debt facilities above (each Level 2 securities) is determined using over-the-counter market quotes and benchmark yields received from independent vendors. Fair value amount presented reflect the Company’s carrying value of debt, net of original issuance discount.

There were no other significant financial instruments outstanding as of March 31, 2023 and December 31, 2022.

NOTE 12—PROVISION FOR INCOME TAXES

	Three Months Ended
	March 31,
	2023			2022
Effective income tax rate		25.4	%		56.9	%

Benefit from income taxes for the three months ended March 31, 2023 totaled $16.7 million, resulting in an effective tax rate of 25.4%. Provision for income taxes for the three months ended March 31, 2022 totaled $22.6 million, resulting in an effective tax rate of 56.9%.

The most significant driver of the decrease in the effective income tax rate for the three months ended March 31, 2023 compared to the prior year was the change in the Company’s forecasted jurisdictional mix of earnings, where income expected to be generated in higher rate jurisdictions exceeds income expected to be generated in lower rate jurisdictions, partially offset by losses not anticipated to provide a tax benefit.

The effective income tax rate for the three months ended March 31, 2022 was primarily impacted by a $35.6 million charge related to the European Commission request for information, as described within Note 13 in the condensed consolidated financial statements, for which the Company estimates no tax benefit.

NOTE 13—COMMITMENTS AND CONTINGENCIES

Environmental Matters

Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law, existing technologies and other information. Pursuant to the terms of the agreement associated with the Company’s formation, the pre-closing environmental liabilities were retained by Dow, and Dow agreed, subject to temporal, monetary, and other limitations to indemnify the Company from and against environmental liabilities incurred or relating to the predecessor periods. Other than certain immaterial environmental liabilities assumed as part of the PMMA Acquisition and the Aristech Surfaces Acquisition, no material environmental claims have been asserted against the Company, and the Company does not have any material accrued obligations for any Superfund Sites. As of March 31, 2023 and December 31, 2022, the Company had $3.5 million of accrued obligations for environmental remediation or restoration costs, which were recorded at fair value within the opening balance sheets of the PMMA business and Aristech Surfaces during 2021.

20

On March 24, 2023, due to equipment failure at the Bristol, Pennsylvania facility, operated by our wholly-owned subsidiary, Altuglas LLC, an accidental release of a latex emulsion product occurred, which ultimately flowed into a local waterway (the “Bristol Spill”). We reported the event and cooperated closely with local, state, and federal authorities on the response activities. Water sampling conducted by the authorities did not detect site-related material in the waterway. See “Litigation Matters” below for information on environmental proceedings related to this incident. In the event of one or more adverse determinations related to this matter, it is possible that the ultimate liability resulting from this matter and the impact on the Company’s results of operations could be material.

Inherent uncertainties exist in the Company’s potential environmental liabilities primarily due to unknown conditions, whether future claims may fall outside the scope of the indemnity, changing governmental regulations and legal standards regarding liability, and evolving technologies for handling site remediation and restoration. In connection with the Company’s existing indemnification, the possibility is considered remote that environmental remediation costs will have a material adverse impact on the condensed consolidated financial statements over the next 12 months.

Purchase Commitments

In the normal course of business, the Company has certain raw material purchase contracts where it is required to purchase certain minimum volumes at current market prices. These commitments range from one to four years. In certain raw material purchase contracts, the Company has the right to purchase less than the required minimums and pay a liquidated damages fee, or, in case of a permanent plant shutdown, to terminate the contracts. In such cases, these obligations would be less than the annual commitment as disclosed in the Notes to Consolidated Financial Statements included in the Annual Report.

Asset Retirement Obligations

The Company has built certain manufacturing facilities on leased land and is required to remove these facilities at the end of the corresponding contract term. Legal obligations for these demolition and decommissioning activities exist in connection with the retirement of these assets triggered upon closure of the facilities. In instances when the Company plans to continue operations at these facilities indefinitely, and therefore, a reasonable estimate of fair value cannot be determined, an asset retirement obligation is not recognized.

In connection with the Asset Restructuring Plan as described within Note 17, the Company concluded the Boehlen, Germany site no longer had an indeterminate life. Accordingly, during the fourth quarter of 2022, the Company recorded the fair value of an asset retirement obligation and a corresponding asset retirement cost, which was capitalized as part of the carrying amount of the related long-lived assets and depreciated over the asset’s shortened useful life. The asset retirement cost was fully depreciated during the fourth quarter of 2022.

	Balance at
Change in asset retirement obligation	March 31, 2023
Balance at beginning of period	$	35.8
Obligations incurred		0.9
Settlements		(2.2)
Accretion expense		0.5
Currency translation adjustment		0.6
Balance at end of period	$	35.6

Accretion expense is included within “Selling, general and administrative expenses” in the condensed consolidated statement of operations. The current portion of the asset retirement obligation is recorded within “Accrued expenses and other current liabilities” and the long-term portion is recorded within “Other noncurrent obligations” in the condensed consolidated balance sheets. As of March 31, 2023 and December 31, 2022, the current portion was $24.6 million and $25.3 million, respectively, and the long-term portion was $11.0 million and $10.5 million, respectively.

Litigation Matters

From time to time, the Company may be subject to various legal claims and proceedings incidental to the normal conduct of business, relating to such matters as employees, product liability, antitrust/competition, past waste disposal practices and release of chemicals into the environment. While it is impossible at this time to determine with certainty the ultimate outcome of these routine claims, the Company does not believe that the ultimate resolution of these claims

21

will have a material adverse effect on the Company’s results of operations, financial condition or cash flow. Legal costs, including those legal costs expected to be incurred in connection with a loss contingency, are expensed as incurred.

Legal Proceedings related to the Bristol Spill

(a) Jonnie Helfrich v. Trinseo PLC (No. 2:23-cv-01525) (United States District Court for the Eastern District of Pennsylvania)

On April 20, 2023, a complaint was filed which purports to be on behalf of a class of purchasers of the Company’s securities between May 3, 2021 and March 27, 2023. It names as defendants the Company and our chief executive officer and chief financial officer, and seeks unspecified damages and other relief for alleged violations of Sections 10(b) and 20(a) of, and Rule 10b-5 under, of the Securities Exchange Act of 1934. Given the early stage of this matter, we are not able to estimate whether a material loss to our business is probable or remote, or estimate a potential range of loss, if any. The Company intends to vigorously defend this action.

(b) Timothy McGraw, Emily Cohen & Danielle Byrd v. Altuglas LLC and Trinseo LLC (Court of Common Pleas of Philadelphia County)

On March 29, 2023, a putative class action complaint was filed which seeks to certify a class that could potentially include all persons and entities that reside in the area served by the Baxter Drinking Water Treatment Plant. The plaintiffs allege claims of breach of duty of care based on negligence as a result of the Bristol Spill, as well as other causes of action, and seek compensatory damages, restitution, or refund of damages, including actual, statutory, and punitive damages, as well as injunctive relief. Given the early stage of this matter, we are not able to estimate whether a material loss to our business is probable or remote, or estimate a potential range of loss, if any. The Company intends to vigorously defend this action.

(c) Environmental Proceedings

On March 25, 2023, the Company received a Notice of Federal Interest from the United States Coast Guard (“USCG”), identifying the Company as a “potentially responsible party” (“PRP”) related to the Bristol Spill. The Company also received a Notice of Federal Assumption and an Administrative Order, dated April 20, 2023 from the USCG, identifying the Company as a PRP related to the Bristol Spill. The USCG notices and order do not designate specific fines or penalties against the Company. It is not possible at this time for the Company to estimate its ultimate liability pursuant to the USCG notices or order, or other potential administrative actions related to the Bristol Spill, whether a material loss to our business is probable or remote, or estimate a potential range of loss, if any.

Synthos Matter

On November 21, 2022, the Company received formal notice from the German Arbitration Institute that Synthos had initiated an arbitration dispute on October 14, 2022 against Trinseo and its following subsidiaries: Trinseo Deutschland GmbH, Trinseo Belgium BV, Trinseo Europe GmbH, and Trinseo Export GmbH, related to Synthos’ purchase of Trinseo’s Rubber Business in 2021.

As discussed in Note 4, Synthos and Trinseo are parties to an asset purchase agreement (“APA”) dated May 21, 2021, whereby Trinseo transferred its Rubber Business to Synthos, pending regulatory approval and other administrative pre-closing conditions, for an enterprise value of approximately $491.0 million. This transaction formally closed on December 1, 2021. Synthos claims that Trinseo did not properly disclose certain information including the natural gas pricing mechanism for the steam which is supplied by a third party to the Rubber Business. Synthos is seeking non-monetary restitution and monetary damages related to the spike of utility prices in Germany that commenced in the fall of 2021.

The Company believes it has valid and prevailing defenses to Synthos’ claims and intends to vigorously defend itself against all allegations.

European Commission Request for Information

On June 6, 2018, Trinseo Europe GmbH, a subsidiary of the Company, received a request for information in the form of a letter from the European Commission Directorate General for Competition (the “European Commission”) related to styrene monomer commercial activity in the European Economic Area. The Company

22

subsequently commenced an internal investigation into these commercial activities and discovered instances of inappropriate activity.

As a result of further developments in this matter, during the first quarter of 2022, the Company recorded a charge of $35.6 million which is included within “Impairment and other charges” on the condensed consolidated statements of operations. In November 2022, the Company reached a final settlement with the European Commission in respect of this matter of $33.8 million, adjusted for foreign exchange rate impacts, which was subsequently paid in full in December 2022.

NOTE 14—PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS

The components of net periodic benefit costs for all significant plans were as follows:

	Three Months Ended				Three Months Ended
	March 31,				March 31,
	Non-U.S. Defined Benefit Pension Plans				U.S. Defined Benefit Pension
	2023		2022		2023		2022
Net periodic benefit cost
Service cost	$	2.0	$	3.2	$	0.1	$	0.2
Interest cost		1.7		0.7		0.2		0.2
Expected return on plan assets		(0.2)		(0.1)		(0.1)		(0.2)
Amortization of prior service credit		(0.1)		(0.1)		—		—
Amortization of net loss		(0.8)		0.7		—		—
Net periodic benefit cost	$	2.6	$	4.4	$	0.2	$	0.2

The Company had less than $0.2 million of net periodic benefit costs for its other postretirement plans for the three months ended March 31, 2023 and 2022.

Service cost related to the Company’s defined benefit pension plans and other postretirement plans is included within “Cost of sales” and “Selling, general and administrative expenses,” whereas all other components of net periodic benefit cost are included within “Other expense (income), net” in the condensed consolidated statements of operations. As of March 31, 2023 and December 31, 2022, the Company’s benefit obligations included primarily in “Other noncurrent obligations” in the condensed consolidated balance sheets were $183.4 million and $177.8 million, respectively.

The Company made cash contributions and benefit payments to unfunded plans of approximately $1.7 million during the three months ended March 31, 2023. The Company expects to make additional cash contributions, including benefit payments to unfunded plans, of approximately $11.4 million to its defined benefit plans for the remainder of 2023.

NOTE 15—SHARE-BASED COMPENSATION

Refer to the Annual Report for definitions of capitalized terms not included herein and further background on the Company’s share-based compensation programs included in the tables below.

The following table summarizes the Company’s share-based compensation expense for the three months ended March 31, 2023 and 2022, as well as unrecognized compensation cost as of March 31, 2023:

23

					As of
	Three Months Ended				March 31, 2023
	March 31,				Unrecognized		Weighted
	2023		2022		Compensation Cost		Average Years
RSUs	$	4.8	$	4.6	$	13.5	2.0
Options		2.6		3.0		3.9	1.6
PSUs		0.8		0.7		7.4	2.4
Total share-based compensation expense	$	8.2	$	8.3

The following table summarizes awards granted and the respective weighted average grant date fair value for the three months ended March 31, 2023:

	Three Months Ended
	March 31, 2023
	Awards Granted		Weighted Average Grant Date Fair Value per Award
RSUs		394,292	$	24.10
Options		438,727		10.86
PSUs		219,238		20.23

Option Awards

The following are the weighted average assumptions used within the Black-Scholes pricing model for the Company’s option awards granted during the three months ended March 31, 2023:

	Three Months Ended
	March 31, 2023
Expected term (in years)	5.50
Expected volatility	54.01	%
Risk-free interest rate	4.06	%
Dividend yield	2.00	%

The expected volatility assumption is determined based on the historical volatility of the Company’s publicly traded ordinary shares. The expected term of option awards represents the period of time that option awards granted are expected to be outstanding. For the option awards granted during the three months ended March 31, 2023, the simplified method was used to calculate the expected term, given the Company’s limited historical exercise data. The risk-free interest rate for the periods within the expected term of option awards is based on the U.S. Treasury yield curve in effect at the time of grant. The dividend yield is estimated based on historical and expected dividend activity.

Performance Share Units (PSUs)

The following are the weighted average assumptions used within the Monte Carlo valuation model for PSUs granted during the three months ended March 31, 2023:

		Three Months Ended
		March 31, 2023
Expected term (in years)		3.00
Expected volatility		62.60	%
Risk-free interest rate		4.41	%
Share price	$	24.08

Determining the fair value of PSUs requires considerable judgment, including estimating the expected volatility of the price of the Company’s ordinary shares, the correlation between the Company’s share price and that of its peer companies, and the expected rate of interest. The expected volatility for each grant is determined based on the historical volatility of the Company’s ordinary shares. The expected term of PSUs represents the length of the performance period.

24

The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for a duration equivalent to the performance period. The share price is the closing price of the Company’s ordinary shares on the grant date.

NOTE 16—SEGMENTS

The Company operates under six segments: Engineered Materials, Latex Binders, Plastics Solutions, Polystyrene, Feedstocks, and Americas Styrenics. On January 1, 2023, the Base Plastics segment was renamed to Plastics Solutions to better reflect Trinseo’s strategic focus on providing solutions in areas such as sustainability and material substitution. The Engineered Materials segment includes the Company’s compounds and blends products sold into higher growth and value applications, such as consumer electronics and medical, as well as soft thermoplastic elastomers (“TPEs”) products which are sold into markets such as footwear and automotive. Additionally, following the PMMA Acquisition and the Aristech Surfaces Acquisition in 2021, the Engineered Materials segment also includes PMMA and MMA products, which are sold into a variety of applications including automotive, building & construction, medical, consumer electronics, and wellness, among others. The Latex Binders segment produces styrene-butadiene latex (“SB latex”) and other latex polymers and binders, primarily for coated paper and packaging board, carpet and artificial turf backings, as well as a number of performance latex binders applications, such as adhesive, building and construction and the technical textile paper market. The Plastics Solutions segment contains the results of the acrylonitrile-butadiene-styrene (“ABS”), styrene-acrylonitrile (“SAN”), and polycarbonate (“PC”) businesses, as well as compounds and blends for automotive and other applications. The Plastics Solutions segment also includes the results of Heathland, which was acquired in the first quarter of 2022. The Polystyrene segment includes a variety of general purpose polystyrenes (“GPPS”) and polystyrene that has been modified with polybutadiene rubber to increase its impact resistant properties (“HIPS”). The Feedstocks segment includes the Company’s production and procurement of styrene monomer outside of North America, which is used as a key raw material in many of the Company’s products, including polystyrene, SB latex, and ABS resins. Lastly, the Americas Styrenics segment consists solely of the operations of the Company’s 50%-owned joint venture, Americas Styrenics, a producer of both styrene monomer and polystyrene in North America.

The following table provides disclosure of the Company’s segment Adjusted EBITDA, which is used to measure segment operating performance and is defined below, for the three months ended March 31, 2023 and 2022. Asset and intersegment sales information by reporting segment is not regularly reviewed or included with the Company’s reporting to the chief operating decision maker. Therefore, this information has not been disclosed below. Refer to Note 5 for the Company’s net sales to external customers by segment for the three months ended March 31, 2023 and 2022.

	Engineered		Latex		Plastics						Americas
Three Months Ended (1)	Materials		Binders		Solutions		Polystyrene		Feedstocks		Styrenics
March 31, 2023	$	(11.7)	$	26.0	$	25.6	$	15.7	$	(10.8)	$	17.6
March 31, 2022	$	34.7	$	30.2	$	68.6	$	45.3	$	4.1	$	21.6

(1) The Company’s primary measure of segment operating performance is Adjusted EBITDA, which is defined as income from continuing operations before interest expense, net; provision for income taxes; depreciation and amortization expense; loss on extinguishment of long-term debt; asset impairment charges; gains or losses on the dispositions of businesses and assets; restructuring charges; acquisition related costs and benefits and other items. Segment Adjusted EBITDA is a key metric that is used by management to evaluate business performance in comparison to budgets, forecasts, and prior year financial results, providing a measure that management believes reflects core operating performance by removing the impact of transactions and events that would not be considered a part of core operations. Other companies in the industry may define segment Adjusted EBITDA differently than the Company, and as a result, it may be difficult to use segment Adjusted EBITDA, or similarly named financial measures, that other companies may use to compare the performance of those companies to the Company’s segment performance.

25

The reconciliation of income from continuing operations before income taxes to segment Adjusted EBITDA is as follows:

	Three Months Ended
	March 31,
	2023		2022
Income (loss) from continuing operations before income taxes	$	(65.6)	$	39.7
Interest expense, net		38.3		21.9

Total Restructuring Charges	$	7.7	$	0.4

(1) In December 2022, the Company announced an asset restructuring plan designed to reduce costs, improve profitability, reduce exposure to cyclical markets and elevated natural gas prices, and address market overcapacity. The asset restructuring plan includes (i) closure of manufacturing operations at the styrene production facility in Boehlen, Germany, (ii) closure of one of its production lines at the Stade, Germany polycarbonate plant, and (iii) closure of the PMMA sheet manufacturing site in Matamoros, Mexico. The program is expected to be substantially completed by the end of 2024. In connection with this restructuring plan, during the three months ended March 31, 2023, the Company incurred employee termination benefit charges of $(0.6) million, contract termination charges of $2.5 million, accelerated depreciation charges of $4.0 million, and decommissioning and other charges of $1.8 million. Production at all facilities have ceased and decommissioning activities are expected to continue through the end of 2024. The Company expects to incur incremental contract termination charges of $17.6 million, decommissioning and other charges of $2.2 million, as well as a limited amount of incremental employee termination benefit charges, the majority of which is expected to be paid by the end of 2024. Of the total incremental charges, $18.6 million is expected to be incurred in the Feedstocks segment, and $1.2 million is expected to be incurred in the Plastics Solution segment.

On April 4, 2023, the Company entered into an agreement to sell its land, buildings and equipment in Matamoros, Mexico for a cash consideration of approximately $19.0 million. The transaction is expected to close within the second quarter of 2023.

(2) In May 2021, the Company approved a transformational restructuring program associated with the Company’s strategic initiatives. The Company expects to incur incremental employee termination benefit charges related to impacted employees as of March 31, 2023 of less than $1.0 million, the majority of which are expected to be paid in 2023. As this was identified as a corporate-related activity, the charges related to this restructuring program were not allocated to a specific segment, but rather included within corporate unallocated.

27

Refer to Note 13 for further information regarding the asset retirement obligation. The following table provides a roll forward of the other liability balances associated with the Company’s restructuring activities as of March 31, 2023. Employee termination benefit and contract termination charges are primarily recorded within “Accrued expenses and other current liabilities” in the condensed consolidated balance sheets.

NOTE 19—EARNINGS PER SHARE

Basic earnings per ordinary share (“basic EPS”) is computed by dividing net income available to ordinary shareholders by the weighted average number of the Company’s ordinary shares outstanding for the applicable period. Diluted earnings per ordinary share (“diluted EPS”) is calculated using net income available to ordinary shareholders divided by diluted weighted average ordinary shares outstanding during each period, which includes unvested RSUs, option awards, and PSUs. Diluted EPS considers the impact of potentially dilutive securities except in periods in which there is a loss from continuing operations because the inclusion of the potential ordinary shares would have an anti-dilutive effect.

The following table presents basic EPS and diluted EPS for the three months ended March 31, 2023 and 2022.

29

March 31, 2023, potential shares related to equity-based awards have been excluded from the calculation of diluted EPS, as doing so would be anti-dilutive. There were 0.9 million anti-dilutive shares that have been excluded from the computation of diluted earnings per share for the three months ended March 31, 2022.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

2023 Year-to-Date Highlights

During the three months ended March 31, 2023, Trinseo recognized net loss from continuing operations of $48.9 million and Adjusted EBITDA of $36.3 million. Continued customer destocking and underlying demand weakness from the uncertain economic and geopolitical macroenvironment originating in the second half of 2022 drove lower sales volume and margins across all segments year-over-year. While overall demand remains constrained, especially in building & construction and consumer durables applications, the impact to our operating performance was mitigated from the asset restructuring initiatives that were announced in the fourth quarter of 2022 as well as lower input costs and commercial actions. Refer to the discussion below for further information and refer to “Non-GAAP Performance Measures” for discussion of our use of non-GAAP measures in evaluating our performance and a reconciliation of these measures.

Amid this challenging environment, the Company continues to implement numerous liquidity improvement actions, including reducing working capital, deferring capital expenditures and reducing cash dividends. As a result of these actions, the Company achieved positive cash generation from operating activities, and strong quarter-end liquidity. The Company continues to have access to capital resources, no maintenance covenants on our debt agreements, and no significant debt maturing until September 2024. Refer to the “Capital Resources and Liquidity” section below for further information. Other highlights for the year are described below.

Restarting Exploration for Divestiture of Styrenics Business

In November 2021, the Company announced that it had begun work to explore the divestiture of our styrenics business and subsequently launched a formal sales process in the first quarter of 2022, which was paused in July 2022 as a result of the deterioration of financing markets and the geopolitical economic uncertainty, particularly in the European energy markets. The Company is restarting the sales process due to interest from third parties for all or part of the business. The scope of the potential divestiture is expected to include the Feedstocks and Polystyrene reporting segments as well as our 50% ownership of Americas Styrenics, and will include marketing individual assets and regional businesses as needed in order to ensure the Company obtains full value for the styrenics business.

Sale of Matamoros, Mexico Manufacturing Facility

On April 4, 2023, Trinseo entered into an agreement to sell its land, buildings and equipment at its PMMA sheet manufacturing facility in Matamoros, Mexico for a cash consideration of approximately $19.0 million. The transaction is expected to close within the second quarter of 2023. This site was part of the previously-announced asset restructuring plan approved in the fourth quarter of 2022 to consolidate our sheet manufacturing business and optimize our resources.

Bristol Spill

On March 24, 2023, due to equipment failure at the Bristol, Pennsylvania facility, operated by our wholly-owned subsidiary, Altuglas LLC, an accidental release of a latex emulsion product occurred, which ultimately flowed into a local waterway (the “Bristol Spill”). We reported the event and cooperated closely with local, state, and federal authorities on the response activities. Water sampling conducted by the authorities did not detect site-related material in the waterway. The safety of our employees, our communities and our environment are a top priority, and we are committed to operate safely and without disturbance to our community. Refer to Note 13 in our condensed consolidated financial statements for additional information related to this matter.

Three Months Ended – March 31, 2023 vs. March 31, 2022

Net Sales

Net sales decreased 28% year-over-year. Lower sales volumes resulted in a 20% decrease from continued customer destocking and underlying demand weakness from an uncertain economic and geopolitical macroenvironment, particularly in applications supporting building & construction and consumer durables. Additionally, a decrease of 7% was related to lower selling prices from the pass through of lower raw material costs.

Cost of Sales

The 21% decrease in cost of sales was primarily attributable to a 17% decrease due to lower sales volumes and a 9% decrease in raw material costs. Natural gas hedges contributed to an $18.8 million unfavorable impact year-over-year.

Gross Profit

The decrease in gross profit of 79% was primarily attributable to lower sales volumes as discussed above as well as lower margins from weaker market conditions including low demand and available supply. Margins were also pressured by unfavorable impacts from natural gas hedges as discussed above. See the segment discussion below for further information.

Selling, General and Administrative Expenses (SG&A)

The $12.0 million, or 12%, decrease in SG&A was primarily due to a decrease of $17.7 million in costs associated with the Company’s strategic initiatives, including the exploration of a potential divestiture of our styrenics business, a $3.1 million decrease in acquisition transaction and integration costs, and a $2.1 million decrease in costs incurred in connection with the Company’s enterprise resource planning system upgrade. Offsetting these decreased costs was a $3.3 million increase in restructuring costs, driven by the asset restructuring plan approved in the fourth quarter of 2022, a $3.1 million increase in depreciation expense, and a $1.6 million increase in travel-related expenses.

32

Equity in Earnings of Unconsolidated Affiliates

The decrease in equity earnings from Americas Styrenics of $4.0 million was due to lower styrene margin which was partially offset by higher polystyrene margin.

Impairment and Other Charges

During the three months ended March 31, 2023 and 2022, the Company recorded impairment charges of $0.3 million and $0.7 million, respectively, related to our Boehlen styrene monomer assets, as described within Note 11 in the condensed consolidated financial statements. Additionally, during the three months ended March 31, 2022, the Company recorded an estimated liability of $35.6 million related to the European Commission request for information, as described within Note 13 in the condensed consolidated financial statements.

Interest Expense, Net

The increase in interest expense, net of $16.4 million, or 75%, was primarily attributable to the increase in the LIBO rate year-over-year. Refer to Note 8 in the condensed consolidated financial statements for further information.

Other Expense (Income), Net

Other income, net for the three months ended March 31, 2023 was $2.9 million, which was primarily driven by foreign exchange transaction gains of $2.7 million. These net foreign exchange transaction gains included $10.5 million of gains primarily from the remeasurement of our euro-denominated payables due to the relative changes in rates between the U.S. dollar and the euro during the period, partially offset by $7.8 million of losses from our foreign exchange forward contracts.

Other expense, net for the three months ended March 31, 2022 was $3.0 million, which included a $1.2 million of expense related to the non-service cost components of net periodic benefit cost as well as foreign exchange transaction losses of $1.4 million. These net foreign exchange transaction losses included $10.2 million of losses primarily from the remeasurement of our euro denominated payables due to the relative changes in rates between the U.S. dollar and the euro during the period, partially offset by $8.8 million of gains from our foreign exchange forward contracts.

Provision for (Benefit from) Income Taxes

Benefit from income taxes for the three months ended March 31, 2023 totaled $16.7 million, resulting in an effective tax rate of 25.4%. Provision for income taxes for the three months ended March 31, 2022 totaled $22.6 million, resulting in an effective tax rate of 56.9%.

The decrease in provision for income taxes is primarily driven by the decrease of $105.3 million in income from continuing operations before income taxes.

Net Income (Loss) from Discontinued Operations, Net of Income Taxes

Net income (loss) from discontinued operations, net of income taxes during the three months ended March 31, 2022 was $(0.4) million, and was related to the results and sale of our Synthetic Rubber business. Refer to Note 4 in the condensed consolidated financial statements for further information.

Outlook

While some of the challenging operating conditions from the second half of 2022 have persisted into the beginning of 2023, such as customer destocking and underlying demand weakness, we have seen a meaningful decrease in European natural gas prices and, with the removal of COVID-related restrictions in China, more limited arbitrage opportunities for lower-cost standard grade products to enter Europe from Asia. Despite continued demand weakness, we expect improved profitability from higher margins, as a result of moderating input costs and pricing initiatives, as well as cost savings from our previously announced asset restructuring initiatives. We expect additional improvement in the second quarter and the rest of the year from lower input and other costs, with a gradual demand increase through the end of the year. Market recovery and natural gas hedges remain a headwind, although natural gas hedge losses are expected to decrease as current forward rates stabilize.

33

The Company has access to capital resources and continues to focus on liquidity improvement actions to manage the anticipated impact of the challenging macroeconomic environment on our business operations for the foreseeable future. The profitability improvement factors noted above, coupled with certain cash preservation initiatives that we have undertaken, such as a reduction in working capital, capital expenditure deferments, and a planned further substantial reduction to our cash dividend, will strengthen our liquidity and balance sheet and are expected to position us to deliver sustained financial strength.

Selected Segment Information

The following sections describe net sales, Adjusted EBITDA, and Adjusted EBITDA margin by segment for the three months ended March 31, 2023 and 2022. Inter-segment sales have been eliminated. Refer to Note 16 in the condensed consolidated financial statements for further information on our segments, as well as for a detailed definition of Adjusted EBITDA and a reconciliation of income from continuing operations before income taxes to segment Adjusted EBITDA.

Engineered Materials Segment

Our Engineered Materials segment consists of rigid thermoplastic compounds and blends products sold into high growth and high value applications in markets such as consumer electronics and medical, as well as soft thermoplastic elastomers (“TPEs”) products which are sold into markets such as footwear and automotive.

Adjusted EBITDA margin		(6)	%		12	%

Three Months Ended – March 31, 2023 vs. March 31, 2022

The 30% decrease in net sales was primarily attributable to a 23% decrease due to lower sales volumes from weak underlying demand and continued customer destocking, particularly in building & construction, consumer electronics, and wellness applications. Lower pricing also contributed to a 6% decrease year-over-year.

The $46.4 million, or 134%, decrease in Adjusted EBITDA was primarily due to a decrease of $18.0 million, or 52%, due to lower sales volumes as described above. Lower margins resulted in a decrease of $24.7 million, or 71%, due to weaker MMA market conditions, as well as a $9.6 million unfavorable impact from natural gas hedges. Higher fixed costs also resulted in a $6.1 million, or 18%, decrease in Adjusted EBITDA due to manufacturing cost under absorption.

Latex Binders Segment

Our Latex Binders segment produces styrene-butadiene latex (“SB latex”) and other latex polymers and binders primarily for coated paper and packaging board, carpet and artificial turf backings, as well as a broad range of

34

performance latex binders products, including SB latex, styrene-acrylate latex (“SA latex”), and vinylidene chloride latex for coatings, adhesives, sealants, and elastomers (“CASE”) applications.

Adjusted EBITDA margin		10	%		10	%

Three Months Ended – March 31, 2023 vs. March 31, 2022

The 19% decrease in net sales was primarily due to a 14% decrease due to lower sales volumes across all regions and applications and a 3% decrease in pricing from the pass through of lower raw material costs.

The $4.2 million, or 14%, decrease in Adjusted EBITDA was primarily due to a decrease of $10.6 million, or 35%, from lower sales volumes from customer destocking and reduced demand in building & construction applications, in addition to a decrease of $0.8 million, or 3%, due to unfavorable foreign exchange rate impacts. These decreases were partially offset by a $7.5 million, or 25%, increase attributable to higher margins from favorable pricing initiatives.

Plastics Solutions Segment

On January 1, 2023, the Base Plastics segment was renamed to Plastics Solutions. Our Plastics Solutions segment consists of a variety of compounds and blends, the majority of which are for automotive applications. The segment also includes our acrylonitrile-butadiene-styrene (“ABS”), styrene-acrylonitrile (“SAN”), and polycarbonate (“PC”) businesses. The Plastics Solutions segment also includes the results of Heathland, which was acquired in the first quarter of 2022. However, this did not have a material impact on sales or Adjusted EBITDA for the period.

Adjusted EBITDA margin		9	%		17	%

Three Months Ended – March 31, 2023 vs. March 31, 2022

Net sales decreased by 27% year-over-year, primarily due to lower sales volume which contributed a 20% decrease. Sales volumes were primarily impacted by a decrease in polycarbonate from the announced shutdown of one production line as well as in copolymers in building & construction, industrial, and consumer durables applications, partially offset by higher volumes to automotive applications. Also contributing to the overall decrease was a 5% decrease from lower pricing due to the pass through of lower raw material costs.

The $43.0 million, or 63%, decrease in Adjusted EBITDA was primarily due to lower sales volumes and margins. Lower sales volumes, as described above, contributed to a $20.7 million, or 30%, decrease in Adjusted EBITDA. In addition, Adjusted EBITDA decreased by $16.0 million, or 23%, due to lower margins in polycarbonate and ABS products from weaker market conditions. Higher fixed costs also contributed a $4.4 million, or 6%, decrease in Adjusted EBITDA. Volumes supporting automotive applications improved 6% versus prior year, mainly from Europe and North America, as production and supply chain constraints eased.

Polystyrene Segment

Our product offerings in our Polystyrene segment include a variety of general purpose polystyrenes (“GPPS”) and polystyrene that has been modified with polybutadiene rubber to increase its impact resistant properties (“HIPS”). These products provide customers with performance and aesthetics at a low cost across applications, including appliances,

35

packaging, including food packaging and food service disposables, consumer electronics, and building and construction materials.

Three Months Ended – March 31, 2023 vs. March 31, 2022

Net sales decreased by 34% year-over-year. Lower sales volumes due to weaker demand in appliance and building & construction applications led to a 22% decrease in net sales from the prior year. Also contributing to the overall decrease was a 10% decrease from lower pricing, primarily from the pass through of lower styrene costs.

The $29.6 million, or 65%, decrease in Adjusted EBITDA was primarily due to weaker demand which negatively impacted volumes and margins, particularly in building & construction and appliance applications. This resulted in a decrease of $13.1 million, or 29%, due to lower volumes, and a decrease of $17.7 million, or 39%, due to lower margins. These decreases were partially offset by an increase of $1.8 million, or 4%, from lower fixed costs.

Feedstocks Segment

The Feedstocks segment includes the Company’s production and procurement of styrene monomer outside of North America, which is used as a key raw material for the production of polystyrene, expandable polystyrene, SAN resins, SA latex, SB latex, ABS resins, and unsaturated polyethylene resins.

Three Months Ended – March 31, 2023 vs. March 31, 2022

Net sales decreased 39% year-over-year. Lower styrene-related sales volume resulted in a 19% decrease along with a 17% decrease due to lower pricing.

The decrease of $14.9 million in Adjusted EBITDA was primarily attributed to a $15.4 million, or 379%, decrease from lower styrene margins, including impacts from a $7.3 million unfavorable net timing variance. The styrene plant in Terneuzen, the Netherlands was restarted in late January 2023 and, as part of our asset restructuring plan, the Boehlen, Germany styrene plant was permanently closed in December 2022.

Americas Styrenics Segment

This segment consists solely of the equity earnings from of our 50%-owned joint venture, Americas Styrenics, a producer of both styrene monomer and polystyrene in North America. Styrene monomer is a basic building block of plastics and a key input to many of the Company’s products, as well as a key raw material for the production of polystyrene. Major applications for the polystyrene products Americas Styrenics produces include appliances, food packaging, food service disposables, consumer electronics, and building and construction materials.

Three Months Ended – March 31, 2023 vs. March 31, 2022

The decrease in Adjusted EBITDA was mainly due to lower styrene margin which was partially offset by higher polystyrene margin.

Non-GAAP Performance Measures

We present Adjusted EBITDA as a non-GAAP financial performance measure, which we define as income from continuing operations before interest expense, net; provision for income taxes; depreciation and amortization expense; loss on extinguishment of long-term debt; asset impairment charges; gains or losses on the dispositions of businesses and assets; restructuring charges; acquisition related costs and other items. In doing so, we are providing management, investors, and credit rating agencies with an indicator of our ongoing performance and business trends, removing the impact of transactions and events that we would not consider a part of our core operations.

There are limitations to using the financial performance measures such as Adjusted EBITDA. This performance measure is not intended to represent net income or other measures of financial performance. As such, it should not be used as an alternative to net income as an indicator of operating performance. Other companies in our industry may define Adjusted EBITDA differently than we do. As a result, it may be difficult to use this or similarly-named financial measures that other companies may use, to compare the performance of those companies to our performance. We compensate for these limitations by providing a reconciliation of this performance measure to our net income, which is determined in accordance with GAAP.

Adjusted EBITDA is calculated as follows for the three months ended March 31, 2023 and 2022:

	Three Months Ended

Net income (loss)	$	(48.9)	$	16.7

Other items(f)		3.6		23.4
Adjusted EBITDA	$	36.3	$	177.6

(a) EBITDA is a non-GAAP financial performance measure that we refer to in making operating decisions because we believe it provides our management as well as our investors and credit agencies with meaningful information regarding the Company’s operational performance. We believe the use of EBITDA as a metric assists our board of directors, management and investors in comparing our operating performance on a consistent basis. Other companies in our industry may define EBITDA differently than we do. As a result, it may be difficult to use EBITDA, or similarly-named financial measures that other companies may use, to compare the performance of those companies to our performance. We compensate for these limitations by providing reconciliations of our EBITDA results to our net income, which is determined in accordance with GAAP.

(b) Amounts for the three months ended March 31, 2023 and 2022 primarily relate to charges incurred in connection with the Company’s various restructuring programs. Refer to Note 17 in the condensed consolidated financial statements for further information.

(c) Amounts for the three months ended March 31, 2022 relate to expenses incurred for the Company’s acquisition and integration of the PMMA business and Aristech Surfaces Acquisitions. Refer to Note 3 in the condensed consolidated financial statements for further information.

(d) Amounts for the three months ended March 31, 2023 and 2022 primarily relate to the impairment of the Company’s styrene monomer assets in Boehlen, Germany, as described within Note 11 in the condensed consolidated financial statements.

(e) Amount for the three months ended March 31, 2022 relate to the estimated liability recorded in connection with the European Commission request for information, as described in Note 13 in the condensed consolidated financial statements.

(f) Other items for the three months ended March 31, 2023 and 2022 primarily relate to fees incurred in conjunction with certain of the Company’s strategic initiatives, including the potential divestiture of our styrenics business and our transition to a new enterprise resource planning system.

Liquidity and Capital Resources

Cash Flows

The table below summarizes our primary sources and uses of cash for the three months ended March 31, 2023 and 2022. We have derived the summarized cash flow information from our unaudited financial statements.

Operating Activities

Net cash provided by operating activities from continuing operations during the three months ended March 31, 2023 totaled $45.4 million, which included $20.0 million of dividends received from Americas Styrenics. Although operating results continued to be challenged by customer destocking and macroeconomic conditions, which resulted in reduced customer demand and negative earnings, there was a significant working capital release during the quarter. This working capital release was primarily a result of targeted inventory control actions and cash improvement initiatives. Net cash used in operating activities from discontinued operations during the three months ended March 31, 2023 was not significant.

Net cash used in operating activities from continuing operations during the three months ended March 31, 2022 totaled $5.2 million. Solid earnings during the period, including $7.5 million of dividends received from Americas Styrenics, were more than offset by a significant working capital build. This working capital build was driven by significantly increasing raw material and utility prices, coupled with a build of inventory ahead of planned turnaround activities. Net cash provided by operating activities from discontinued operations during the three months ended March 31, 2022 totaled $0.2 million.

38

Investing Activities

Net cash used in investing activities from continuing operations during the three months ended March 31, 2023 totaled $21.8 million, which was primarily attributable to capital expenditures. The Company has taken proactive measures to reduce and defer capital expenditures during the year as part of our liquidity improvement actions.

Net cash used in investing activities from continuing operations during the three months ended March 31, 2022 totaled $46.1 million, which was primarily attributable to net cash paid for asset or business acquisitions of $22.2 million (see Note 3), and capital expenditures, including cash spent for our ongoing ERP upgrade, of $23.9 million. Net cash used in investing activities from discontinued operations during the three months ended March 31, 2022 totaled $0.9 million.

Financing Activities

Net cash used in financing activities during the three months ended March 31, 2023 totaled $20.5 million. This activity was primarily due to $11.8 million of dividends paid, and $6.3 million in debt repayments.

Net cash used in financing activities during the three months ended March 31, 2022 totaled $70.6 million. This activity was primarily due to $51.9 million of payments related to the repurchase of ordinary shares, $12.4 million of dividends paid, $3.6 million of net repayments of short-term borrowings, and $3.6 million of net principal payments related to our 2024 Term Loan B and 2028 Term Loan B during the period. This activity was partially offset by $1.7 million in proceeds from the exercise of option awards during the period.

Free Cash Flow

We use Free Cash Flow as a non-GAAP measures to evaluate and discuss the Company’s liquidity position and results. Free Cash Flow is defined as cash from operating activities, less capital expenditures. We believe that Free Cash Flow provides an indicator of the Company’s ongoing ability to generate cash through core operations, as it excludes the cash impacts of various financing transactions as well as cash flows from business combinations that are not considered organic in nature. We also believe that Free Cash Flow provides management and investors with useful analytical indicator of our ability to service our indebtedness, pay dividends (when declared), and meet our ongoing cash obligations.

Free Cash Flow is not intended to represent cash flows from operations as defined by GAAP, and therefore, should not be used as an alternative for that measure. Other companies in our industry may define Free Cash Flow differently than we do. As a result, it may be difficult to use this or similarly-named financial measures that other companies may use, to compare the liquidity and cash generation of those companies to our own. We compensate for these limitations by providing a reconciliation to cash provided by operating activities from continuing operations, which is determined in accordance with GAAP.

Refer to the discussion above for significant impacts to cash provided by operating activities for the three months ended March 31, 2023 and 2022.

Capital Resources and Liquidity

We require cash principally for day-to-day operations, to finance capital investments and other initiatives, to purchase materials, to service our outstanding indebtedness, and to fund the return of capital to shareholders via dividend payments and ordinary share repurchases, when deemed appropriate. Our sources of liquidity include cash on hand, cash flow from operations from continuing operations, and amounts available under the Senior Credit Facility and the Accounts Receivable Securitization Facility (discussed further below).

39

At March 31, 2023 and December 31, 2022, we had $2,350.6 million and $2,353.7 million, respectively, in outstanding indebtedness and $658.5 million and $701.3 million, respectively, in working capital. In addition, as of March 31, 2023 and December 31, 2022, we had $123.8 million and $168.7 million, respectively, of foreign cash and cash equivalents on our balance sheet, outside of Ireland, our country of domicile, all of which is readily convertible into other foreign currencies, including the U.S. dollar. Our intention is not to permanently reinvest our foreign cash and cash equivalents. Accordingly, we record deferred income tax liabilities related to the unremitted earnings of our subsidiaries.

The following table outlines our outstanding indebtedness as of March 31, 2023 and December 31, 2022 and the associated interest expense, including amortization of deferred financing fees and debt discounts. Effective interest rates for the borrowings included in the table below exclude the impact of deferred financing fee amortization, certain other fees charged to interest expense (such as fees for unused commitment fees during the period), and the impacts of derivatives designated as hedging instruments. For definitions of capitalized terms not included herein, refer to our Annual Report on Form 10-K (“Annual Report”).

As of March 31, 2023, our Senior Credit Facility included the 2026 Revolving Facility, which is scheduled to mature in May 2026 and had a borrowing capacity of $375.0 million and $22.0 million outstanding letters of credit. The 2026 Revolving Facility contains a springing covenant which applies when 30% or more is drawn from the facility. This covenant requires the Company to meet a first lien net leverage ratio (as defined in our secured credit agreement) not to exceed 3.50x at the end of each financial quarter. As of March 31, 2023, the first lien net leverage ratio was 4.85x, and as such, the Company had $100.5 million of funds available for borrowing (net of $12.0 million outstanding letters of credit as defined in the secured credit agreement). Further, as of March 31, 2023, the Company is required to pay a quarterly commitment fee in respect of any unused commitments under the 2026 Revolving Facility equal to 0.375% per annum.

Also included in our Senior Credit Facility is our 2024 Term Loan B (with original principal of $700.0 million, maturing in September 2024), and our 2028 Term Loan B (with original principal of $750.0 million, maturing in May 2028).

As of March 31, 2023, our 2025 Senior Notes, as issued under the Indenture executed in 2017, include $500.0 million aggregate principal amount of 5.375% senior notes that mature on September 1, 2025.

As of March 31, 2023, our 2029 Senior Notes, as issued under the Indenture executed in 2021, include $447.0 million aggregate principal amount of 5.125% senior notes that mature on April 1, 2029.

We also continue to maintain our Accounts Receivable Securitization Facility, which matures in November 2024 and has an outstanding borrowing capacity of $150.0 million. As of March 31, 2023, there were no amounts outstanding under this facility and the Company had approximately $150.0 million of accounts receivable available to support this facility, based on the pool of eligible accounts receivable. Refer to Note 8 in the consolidated financial statements for further information on the facility.

Our ability to raise additional financing and our borrowing costs may be impacted by short- and long-term debt

40

ratings assigned by independent rating agencies, which are based, in significant part, on our performance as measured by certain credit metrics such as interest coverage and leverage ratios.

We and our subsidiaries, affiliates or significant shareholders may from time to time seek to retire or purchase our outstanding debt through cash purchases in the open market, privately negotiated transactions, exchange transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

Trinseo Materials Operating S.C.A. and Trinseo Materials Finance, Inc. (the “Issuers” of our 2029 Senior Notes and 2025 Senior Notes and “Borrowers” under our Senior Credit Facility) are dependent upon the cash generation and receipt of distributions and dividends or other payments from our subsidiaries and joint venture in order to satisfy their debt obligations. There are no known significant restrictions by third parties on the ability of subsidiaries of the Company to disburse or dividend funds to the Issuers and the Borrowers in order to satisfy these obligations. However, as the Company’s subsidiaries are located in a variety of jurisdictions, the Company can give no assurances that our subsidiaries will not face transfer restrictions in the future due to regulatory or other reasons beyond our control.

The Senior Credit Facility and Indentures also limit the ability of the Borrowers and Issuers, respectively, to pay dividends or make other distributions to Trinseo PLC, which could then be used to make distributions to shareholders. During the three months ended March 31, 2023, the Company declared dividends of $0.14 per ordinary share, totaling $5.2 million, all of which was accrued as of March 31, 2023 and was paid in April 2023. These dividends are well within the available capacity under the terms of the restrictive covenants contained in the Senior Credit Facility and Indentures. Further, additional capacity continues to be available under the terms of these covenants to support expected future dividends to shareholders, should the Company continue to declare them.

Despite the challenging and uncertain market conditions we are continuing to experience in 2023, the Company generated positive cash flows from operating activities for the three months ended March 31, 2023 primarily due to our cash improvement initiatives and working capital reductions. We believe funds provided by operations, our cash and cash equivalent balances of $217.1 million as of March 31, 2023, coupled with borrowings available under our 2026 Revolving Facility and our Accounts Receivable Securitization Facility totaling a minimum of $250.5 million, will be adequate to meet all necessary operating and capital expenditures for at least the next 12 months under the current operating environment, while continuing to evolve as a specialty material and sustainable solutions provider. As we weather these trough conditions, the Company maintains access to capital resources and will continue to focus on liquidity improvement actions until customer destocking ends and sales volumes stabilize, at which point we expect our cash flow generation to resume to normal operating levels.

Further, we also believe that our financial resources will allow us to manage the anticipated impact of this challenging macroeconomic environment on our business operations for the foreseeable future, which could include lower demand, reductions in revenue or delays in payments from customers and other third parties. Our ability to generate cash from operations to pay our indebtedness and meet other liquidity needs is subject to certain risks described herein and under Part I, Item 1A – Risk Factors of our Annual Report, as well as risk factors included in Part II, Item 1A herein. As of March 31, 2023, we were in compliance with all the covenants and default provisions under our debt agreements. Refer to our Annual Report for further information on the details of the covenant requirements.

Contractual Obligations and Commercial Commitments

There have been no material revisions outside the ordinary course of business to our contractual obligations as described within “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Contractual Obligations and Commercial Commitments” within our Annual Report.

Critical Accounting Policies and Estimates

Our unaudited interim condensed consolidated financial statements are based on the selection and application of significant accounting policies. The preparation of unaudited interim condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and revenues and expenses at the date of and during the reporting period. Actual results could differ from those estimates. However, we are not currently aware of any reasonably likely events or circumstances that would result in materially different results.

41

We describe our significant accounting policies in Note 2, Basis of Presentation and Summary of Significant Accounting Policies, in the Notes to Consolidated Financial Statements included in our Annual Report, while we discuss our critical accounting policies and estimates in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” within our Annual Report. There have been no material revisions to the significant accounting policies or critical accounting policies and estimates as filed in our Annual Report.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Recent Accounting Pronouncements

We describe the impact of recent accounting pronouncements in Note 2 of our condensed consolidated financial statements, included elsewhere within this Quarterly Report.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

As discussed in “Quantitative and Qualitative Disclosures About Market Risk” within our Annual Report, we are exposed to changes in interest rates and foreign currency exchange rates as well as changes in the prices of certain commodities that we use in production. There have been no material changes in our exposure to market risks from the information provided within our Annual Report.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management is responsible for establishing and maintaining internal controls designed to provide reasonable assurance that information required to be disclosed by us in our reports that we file or submit under the Exchange Act (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, with the participation of our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company’s disclosure controls and procedures as of March 31, 2023. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this Quarterly Report were effective to provide the reasonable level of assurance described above.

Changes in Internal Control over Financial Reporting

There were no additional changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) that occurred during the quarter ended March 31, 2023 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

From time to time we may be subject to various legal claims and proceedings incidental to the normal conduct of business, relating to such matters as product liability, antitrust, competition, waste disposal practices, release of chemicals into the environment and other matters that may arise in the ordinary course of our business. Regardless of the outcome, legal proceedings can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors. For information regarding new matters and material developments in legal proceedings during the quarter ended March 31, 2023, see “Litigation Matters” in Note 13 to our condensed consolidated financial statements.

42

Item 1A. Risk Factors

Our business faces various risks. Certain important factors may have a material adverse effect on our business prospects, financial condition and results of operations, and you should carefully consider them. Accordingly, in evaluating our business, we encourage you to consider the risk factors related to our ordinary shares as well those risk factors related to our business and industry which have been previously disclosed in Part 1, Item 1A of our Annual Report for the year ended December 31, 2022. Certain material updates to these risk factors are included below.

We encourage you to consider these risks, in their entirety, in addition to other information contained in or incorporated by reference into this Quarterly Report and our other public filings with the SEC. Other events that we do not currently anticipate or that we currently deem immaterial may also affect our business, prospects, financial condition and results of operations.

We may not be successful in the proposed divestiture of our styrenics businesses.

In May 2023, we announced our intention to restart the sale of our styrenics business, which had been paused since July 2022, including marketing of individual businesses and sites. While the divestiture of our styrenics businesses remains a key part of our transformation strategy, we cannot estimate whether economic conditions and capital markets will sufficiently improve to allow us to restart and successfully complete a sale of all or a portion of our styrenics business, or guarantee that we will be successful in our efforts to restart the sale process, generate interest in a sale of all or a portion of the business, locate an adequate buyer or buyers, or negotiate terms of a sale acceptable to the Company.

A successful divestiture depends on various factors, including our ability to effectively transfer liabilities, contracts, facilities and employees to any purchaser, revise our legal entity structure, negotiate continued equity ownership, identify and separate intellectual property, reduce fixed costs previously associated with the divested assets or business, and collect the proceeds from any sale. Any divestiture may result in a dilutive impact to our future earnings if we are unable to offset the dilutive impacts from the loss of revenue associated with the divested business, as well as significant write-offs, including those related to goodwill and other intangible assets, which could have a material adverse effect on our results of operations and financial condition. All of these efforts require varying levels of management resources, which may divert our attention from other business operations.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

(a) Recent sales of unregistered securities

None.

(b) Use of Proceeds from registered securities

None.

(c) Purchases of Equity Securities by the Issuer and Affiliated Purchasers

The repurchase authorization expires after 18 months and repurchases may be effected through open market purchases, 10b5-1 plans or by other means. There were no share repurchases during the three months ended March 31, 2023. There was $200.0 million remaining for share repurchases as of March 31, 2023.

TRINSEO LLC

EMPLOYMENT AGREEMENT

EMPLOYMENT AGREEMENT (this “Agreement”), dated as of October 15, 2021 (the “Effective Date”), among Trinseo LLC, a Delaware limited liability company, with offices at 1000 Chesterbrook Boulevard, Suite 300, Berwyn, Pennsylvania 19312 (the “Company”), and Paula Cooney, of 100 S. 3^rd Avenue, Unit 1503, Minneapolis, MN 55401 (the “Executive”).

W I T N E S S E T H

WHEREAS, the Company desires to employ the Executive as Senior Vice President, Chief Human Resources Officer of the Company and its ultimate parent Trinseo PLC (the “Parent”) and to pay all of the Executive’s compensation as described in this Agreement;

WHEREAS, Parent desires to grant the Executive certain equity awards described in this Agreement and to guarantee the cash compensation of the Executive payable by the Company hereunder; and

WHEREAS, the Company, Parent and the Executive desire to enter into this Agreement as to the terms of the Executive’s employment with the Company.

NOW, THEREFORE, in consideration of the foregoing, of the mutual promises contained herein and of other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1. POSITION AND DUTIES.

(a)During the Employment Term (as defined in Section 2 hereof), the Executive shall serve as Senior Vice President, Chief Human Resources Officer of the Company and Parent. In this capacity, the Executive shall have the duties, authorities and responsibilities commensurate with the duties, authorities and responsibilities of persons in similar capacities in similarly sized companies, and such other executive duties, authorities and responsibilities as may reasonably be assigned to the Executive that are not inconsistent with the Executive’s position as Senior Vice President, Chief Human Resources Officer of the Company and Parent. The Executive’s primary place of employment with the Company shall be a virtual home office in one of the states where the Company is presently established (which includes Minneapolis); provided that the Executive understands and agrees that the Executive will be required to travel frequently for business purposes. The Executive shall report directly to the Chief Executive Officer and President.

(b)During the Employment Term, the Executive shall devote all of the Executive’s business time, energy, business judgment, knowledge and skill and the Executive’s reasonable best efforts to the performance of the Executive’s duties with the Company and the Parent, provided that the foregoing shall not prevent the Executive from (i) serving on the boards of directors of non-profit organizations and, with the prior written approval of the Board (which approval shall not be unreasonably withheld), other for profit companies, (ii) participating in charitable, civic, educational, professional, community or industry affairs, and (iii) managing the Executive’s passive

personal investments so long as such activities in the aggregate do not violate Section 10 hereof, interfere or conflict with the Executive’s duties hereunder or create a business or fiduciary conflict.

2.EMPLOYMENT TERM AND AGREEMENT TERM.  The Company agrees to employ the Executive pursuant to the terms of this Agreement commencing on November 29, 2021 (“Hire Date”) for an initial one year term, which shall automatically renew for successive one-year periods, unless either party gives three (3) months’ advance written notice of non-renewal. Notwithstanding the foregoing, the Executive’s employment hereunder may be earlier terminated in accordance with Section 7 hereof, subject to Section 8 hereof. The period of time between the Hire Date and the termination of the Executive’s employment hereunder shall be referred to herein as the “Employment Term.”

3.BASE SALARY. During the Employment Term, the Company agrees to pay the Executive a base salary at an annual rate of not less than $500,000, payable in accordance with the regular payroll practices of the Company, but not less frequently than monthly. The Executive’s base salary shall be subject to annual review by the Board (or a committee thereof) during the first ninety (90) days of each calendar year, and the base salary in respect of such calendar year may be increased above, but not decreased below, its level for the preceding calendar year, by the Board. The base salary as determined herein and adjusted from time to time shall constitute “Base Salary” for purposes of this Agreement.

4.ANNUAL BONUS.

(a)During the Employment Term, the Executive shall be eligible for an annual cash performance bonus (an “Annual Bonus”) in respect of each calendar year that ends during the Employment Term, to the extent earned based on performance against objective performance criteria. The performance criteria for any particular calendar year shall be determined in good faith by the Board, after consultation with the Executive, to occur as soon as practicable after the commencement of such calendar year, but no later than ninety (90) days after the commencement of such calendar year. The Executive’s targeted Annual Bonus for a calendar year shall equal 60% of the Executive’s Base Salary for such calendar year (the “Target Bonus”) if target levels of performance for such year are achieved, with greater or lesser amounts (including zero) paid for performance above and below target (such greater and lesser amounts to be determined by a formula established by the Board for such year when it establishes the targets and performance criteria for such year); provided that the Executive’s maximum Annual Bonus for any calendar year during the Employment Term shall equal 200% of the Target Bonus for such calendar year. The Executive’s Target Bonus shall be subject to annual review by the Board (or a committee thereof) during the first ninety (90) days of each calendar year, and the Target Bonus for such calendar year may be increased above, but not decreased below, the levels for the preceding calendar year, by the Board.  For the calendar year 2021, the Executive’s Annual Bonus shall be prorated.

(b)The Executive’s Annual Bonus for a calendar year shall be determined by the Board (or a committee thereof) after the end of the applicable calendar year based on the level of achievement of the applicable performance criteria, and shall be paid to the Executive in the calendar year following the calendar year to which such Annual Bonus relates at approximately the same time annual bonuses are paid to other senior executives of Company and Parent, subject to continued employment at the time of payment (except as otherwise provided in Section 8 hereof).

(c)After 5 years of employment, the Annual Bonus will be treated under the retirement eligible provisions of the Performance Award Plan.

5.EQUITY AWARDS.

(a)The Parent shall grant to the Executive incentive equity awards as herein defined and for subsequent calendar years as may be determined and adjusted from time to time, (the “Long Term Incentive Equity Awards”), with grant date fair value equal to 120% of Base Salary for calendar year 2022, in each case, in the same form and subject to the same vesting terms and conditions as incentive equity awards granted to similarly situated senior executives of the Parent.  As a reference, for calendar year 2021, the Long Term Incentive Equity Awards were allocated as: 30% Stock Options with a 3-year pro rata vesting, 30% Restricted Share Units with 3-year cliff vesting and 40% Performance Units with a 3-year performance vesting measured against Total Shareholder Return.  Equity awards shall commence and be granted annually starting in 2022, according to the Long Term Incentive (“LTI”) Plan.

(b)In addition, in consideration of the Executive joining the Company, the Parent shall issue, on or as soon as practicable after the Hire Date, a one-time special off cycle Long Term Incentive Equity Award with a target amount of $300,000, as Restricted Share Units which shall vest ratably at 1/3 per year each year.

(c)After 5 years of employment the Long Term Incentive Equity Awards will be treated under the retirement eligible provisions of the LTI Plan.

(d)The terms and conditions of the Long Term Incentive Equity Awards will be set forth in award agreements provided by the Parent, electronically or otherwise and will be provided to the Executive as soon as practicable after the grant dates and which the Executive will be required to sign or accept in accordance with the Parent’s acceptance procedures.

6.EMPLOYEE BENEFITS.

(a)BENEFIT PLANS.  During the Employment Term, the Executive shall be entitled to participate in any employee benefit plan that the Company, Parent or any of their direct or indirectly controlled subsidiaries (each an “ Affiliate ”) has adopted or may adopt, maintain or contribute to and which benefit any of the senior executives of the Company, Parent or any Affiliate, on a basis no less favorable than that applicable to any such senior executives, where such basic company paid element (medical, dental, life insurance and disability insurance) shall be effective as of the Hire Date and any additional options elected by the Executive shall be subject to satisfying the applicable eligibility requirements, except to the extent such plans are duplicative of the benefits otherwise provided hereunder. The Executive’s participation in any such employee benefit plan shall be subject to the terms of the applicable plan documents and generally applicable Company policies. Notwithstanding the foregoing, the Company may modify or terminate any employee benefit plan at any time, if and to the extent allowed pursuant to the terms of such plan, provided that any such amendment may have no more adverse effect on the Executive than on any other participant in such plan. The Company may provide perquisites to the Executive at the discretion of the Board.

(b)VACATIONS. During the Employment Term, the Executive shall be entitled to twenty-eight (28) days of paid vacation per calendar year (pro-rated for partial years) in accordance with the Company’s policy on accrual and use applicable to employees as in effect from time to time. For the calendar year 2021, you shall receive five (5) vacation days.

(c)BUSINESS EXPENSES. Upon presentation of reasonable substantiation and documentation as the Company may specify from time to time, the Executive shall be reimbursed in accordance with the Company’s expense reimbursement policies as in effect from time to time, for all reasonable out-of-pocket business expenses incurred and paid by the Executive during the Employment Term and in connection with the performance of the Executive’s duties hereunder.

(d)CASH SIGNING BONUS. In consideration of the Executive joining the Company, the Company shall pay to the Executive a one-time lump sum cash payment in the amount of $300,000 gross (the “Cash Signing Bonus”) which shall be payable as an advance as soon as practical in the next payroll cycle following the Hire Date, which in any event shall be no later than December 31, 2021, and which shall vest ratably at one third (i.e. 1/3) annually and become fully vested after three (3) years from the Hire Date, subject to the Executive’s continued and non-terminated employment with the Company.  In the event that the Executive’s employment with the Company terminates as a result of a termination by the Company for Cause or by the Executive without Good Reason at any time within a period of three (3) years following the Effective Date, the Executive shall be required to repay any portion of the advanced Cash Signing Bonus to the Company that has not been vested. Such amount shall be repaid to the Company no later than thirty (30) days following such termination date and, at the Company’s election, the Company may offset such amount against any amount owed by the Company to the Executive.

7.TERMINATION. The Executive’s employment and the Employment Term shall terminate on the first of the following to occur:

(a)DISABILITY.  Upon ten (10) days’ prior written notice by the Company to the Executive of termination due to Disability. For purposes of this Agreement, “Disability” shall be defined as the inability of the Executive to have performed the Executive’s material duties hereunder due to a physical or mental injury, infirmity or incapacity, which inability shall continue for one hundred and twenty (120) consecutive days or for one hundred eighty (180) days (including weekends and holidays) in any 365-day period as determined by the Company’s outside insurance provider’s physician in consultation with the Executive’s physician. The Executive shall cooperate in all respects with the Company if a question arises as to whether the Executive has become disabled (including, without limitation, submitting to reasonable examinations by one or more medical doctors and other health care specialists selected by the Company and authorizing such medical doctors and other health care specialists to discuss the Executive’s condition with the Company).

(b)DEATH. Automatically upon the date of death of the Executive.

(c)CAUSE. Immediately upon written notice by the Company to the Executive of a termination for Cause. “Cause” shall mean the Executive’s (i) continued failure to follow the lawful and reasonable directives of the Board after written notice from the Board and a period of no less than thirty (30) days to cure such failure; (ii) willful misconduct or gross negligence in the performance of the Executive’s duties; (iii) conviction of, or pleading of guilty or nolo contendere to, a non-vehicular

felony; (iv) material violation of a material written Company or Parent policy that is not cured within fifteen (15) days of written notice from the Board; (v) performance of any material act of theft, embezzlement, fraud or misappropriation of or in respect of the Company’s property; (vi) continued failure to cooperate in any audit or investigation of financial or business practices of the Company or Parent after written request for cooperation from the Board and a period of no less than ten (10) days to cure such failure; (vii) commission of any criminal act or other act involving moral turpitude, sexual harassment or drug  violations (after an independent investigation concludes that such acts occurred and Executive has been presented with opportunity to participate in the investigation); (viii) commission of any willful act which brings public disrepute, contempt, scandal, or ridicule, or which shocks or offends the community or any group or class thereof, or which reflects unfavorably upon Company or Parent and, as a result of such act or involvement, reduces the commercial value of Company's or Parent’s association with Executive; (ix) willful actions (other than legal action or arbitration arising out of this Agreement) or making or authorizing statements in derogation of Company or Parent or their products and such actions or statements become public during the Term that result in damage to the business of the Company; or (x) breach of any of the restrictive covenants set forth in Section 10 hereof or in any other written agreement between the Executive and the Company and/or its affiliates that causes material and demonstrable harm to the Company or Parent and that is not cured within fifteen (15) days of written notice from the Board (a “Material Covenant  Violation”).  

For purposes of this Section 7(c), no act, or failure to act, on the part of the Executive shall be considered “willful” unless it is done, or omitted to be done, by the Executive in bad faith or without reasonable belief that the Executive’s action or omission was in the best interests of the Company. Any act, or failure to act, based upon (A) authority given pursuant to a resolution duly adopted by the Board or the board of directors of the Company or (B) the advice of counsel for the Company or Parent shall be conclusively presumed to be done, or omitted to be done, by the Executive in good faith and in the best interests of the Company. The cessation of employment of the Executive shall not be deemed to be for Cause unless and until there shall have been delivered to the Executive a copy of a resolution duly adopted by the affirmative vote of not less than a majority of the entire membership of the Board (excluding the Executive, if the Executive is a member of the Board) at a meeting of the Board called and held for such purpose (after reasonable notice is provided to the Executive and the Executive is given an opportunity, together with counsel for the Executive, to be heard before the Board), finding that, in the good faith opinion of the Board, the Executive is guilty of the conduct described in one or more of clauses (i) through (x) of the preceding paragraph, and specifying the particulars thereof in detail.

(d)WITHOUT CAUSE. Immediately upon written notice by the Company to the Executive of an involuntary termination without Cause (other than for death or Disability).

(e)GOOD REASON. Upon written notice by the Executive to the Company of a termination for Good Reason. “Good Reason” shall mean the occurrence of any of the following events, without the express written consent of the Executive, unless such events are fully corrected in all material respects by the Company or Parent (as applicable) within thirty (30) days following written notification by the Executive to the Company of the occurrence of one of the reasons set forth below: (i) other than following the receipt of the Company's written notice pursuant to Section 7(d), the material diminution in the Executive’s position, duties or authorities or assignment of duties materially inconsistent with the Executive’s position with Parent, including but not limited to the

Executive ceasing to be the sole SVP, Chief Human Resources Officer of Parent; (ii) a reduction in Base Salary or Target Bonus; (iii) the Company’s failure to grant Executive the Long Term Incentive Equity Awards set forth in Section 5 of this Agreement; or (iv) the Company’s material breach of this Agreement. The Executive shall provide the Company with a written notice detailing the specific circumstances alleged to constitute Good Reason within ninety (90) days after the Executive first gains actual knowledge of the occurrence of such circumstances, and actually terminate employment within thirty (30) days following the expiration of the Company’s thirty (30)-day correction period described above. Otherwise, any claim of such circumstances as “Good Reason” shall be deemed irrevocably waived by the Executive.  For avoidance of doubt, succession planning or successor candidate evaluation by the Company, shall not, by itself, constitute Good Reason.

(f)WITHOUT GOOD REASON. Upon three (3) months’ written notice by the Executive to the Company of a voluntary termination of employment without Good Reason (which the Company may, in its sole discretion, make effective earlier than the expiration of the notice period; provided that if the Company accelerates the effective date of termination, then the Executive will continue to receive Base Salary through the expiration of the three (3) months’ notice period). In such event, the last day of employment as provided in the notice period, or an earlier date at the Company’s option, shall be the Executive’s termination date for all purposes of this Agreement, including without limitation, the termination date for determining termination benefits pursuant to Section 8 hereof. The Company’s election to accelerate the Executive’s termination date shall not be considered a termination by the Company without Cause or constitute Good Reason hereunder. In addition, the Company may transition Executive’s duties and responsibilities to others during the notice period and such diminution of duties and responsibilities shall not constitute Good Reason as provided for herein.

(g)NON-RENEWAL. If the Executive’s employment is terminated by the Company or the Executive due to non-renewal as provided for in Section 2.  If such notice of non-renewal is given by the Executive, then during the three (3) months’ notice period any: (i) diminution in the Executive’s position, duties or authorities or assignment of duties; or (ii) acceleration of the termination date; shall not give rise to Good Reason.  In addition, the Company may transition Executive’s duties and responsibilities to others during the notice period and such diminution of duties and responsibilities shall not constitute Good Reason as provided for herein.

8.CONSEQUENCES OF TERMINATION.

(a)DEATH. In the event that the Executive’s employment and the Employment Term ends on account of the Executive’s death, the Executive’s estate shall be entitled to the following (with the amounts due under Sections 8(a)(i) through 8(a)(v) hereof to be paid, unless otherwise provided below, within sixty (60) days following termination of employment, or such earlier date as may be required by applicable law):

(i)any unpaid Base Salary through the date of termination;

(ii)any Annual Bonus earned but unpaid with respect to the calendar year ending on or preceding the date of termination;

(iii)an amount equal to the pro-rata portion of the Executive’s Target Bonus for the calendar year of termination (determined by multiplying the Target Bonus for the year of termination by a fraction, the numerator of which is the number of days during the calendar year of

termination that the Executive is employed by the Company and the denominator of which is 365); provided that to the extent that the payment of such amount constitutes “nonqualified deferred compensation” for purposes of “Code Section 409A” (as defined in Section 24 hereof), such payment shall be made on the sixtieth (60th) day following such termination ;

(iv)reimbursement for any unreimbursed business expenses incurred through the date of termination;

(v)payment in respect of any accrued but unused vacation time in accordance with Company policy; and

(vi)all other payments, benefits or fringe benefits to which the Executive shall be entitled under the terms of any applicable compensation arrangement or benefit, equity or fringe benefit plan or program or grant or this Agreement (collectively, Sections 8(a)(i) through 8(a)(vi) hereof shall be hereafter referred to as the “Accrued Benefits”) .

(b)DISABILITY. In the event that the Executive’s employment and/or Employment Term ends on account of the Executive’s Disability, the Company shall pay or provide the Executive with the Accrued Benefits.

(c)TERMINATION FOR CAUSE, WITHOUT GOOD REASON OR NON-RENEWAL BY EXECUTIVE. If the Executive’s employment is terminated (x) by the Company for Cause, or (y) by the Executive without Good Reason or the Executive due to non-renewal, the Company shall pay to the Executive the Accrued Benefits; provided that, in the event of a termination for Cause, the Executive shall not be entitled to the benefits described in Sections 8(a)(ii) and 8(a)(iii); and provided further that, in the event of a resignation by the Executive without Good Reason, the Executive shall not be entitled to the benefits described in Section 8(a)(iii).

(d)TERMINATION WITHOUT CAUSE, FOR GOOD REASON OR NON-RENEWAL BY THE COMPANY. If the Executive’s employment by the Company is terminated (x) by the Company other than for Cause pursuant to Section 7(c) hereof, (y) by the Executive for Good Reason (collectively, a “Qualifying Termination”), or (z) non-renewal by the Company; then the Company shall pay or provide the Executive with the following:

(i)the Accrued Benefits;

(ii)subject to the Executive’s not engaging in a Material Covenant Violation or a material breach of Section 11 hereof that is not cured within thirty (30) days of written notice from the Board (a “Material Cooperation Violation”), the Executive shall be entitled to an amount equal to one and one-half (1.5) multiplied by the annual sum of the Executive’s Base Salary and Target Bonus in effect for the then-current year of termination (the “Severance Amount”), paid according to the Company’s standard practices in installments for a period of eighteen (18) months following such termination; provided that to the extent that the payment of any amount constitutes “nonqualified deferred compensation” for purposes of Code Section 409A, any such payment scheduled to occur during the first sixty (60) days following the termination of employment shall not be paid until the sixtieth (60th) day following such termination and shall include payment of any amount that was otherwise scheduled to be paid prior thereto; and

(iii)subject to (A) the Executive’s timely election of continuation coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), (B) the Executive’s continued copayment of premiums at the same level and cost to the Executive as if the Executive were an employee of the Company (excluding, for purposes of calculating cost, an employee’s ability to pay premiums with pre-tax dollars), and (C) the Executive’s not engaging in a Material Covenant Violation or a Material Cooperation Violation, continued participation in the Company’s group health plan (to the extent permitted under applicable law) which covers the Executive (and his eligible dependents) for a period of twelve (12) months and Company paid premiums for a substantially similar health plan coverage for the remainder of the period of eighteen (18) months following such termination, provided that if the Company’s group health plan is self-insured, the Company will report to the appropriate tax authorities taxable income to the Executive equal to the portion of the deemed cost of such participation (based on applicable COBRA rates) not paid by the Executive; provided further, that in the event that the Executive obtains other employment that offers group health benefits, such continuation of coverage by the Company under this Section 8(d)(iii) shall immediately cease once Executive is eligible to enroll in such coverage from his new employer; and provided further, that in the event that the Executive enrolls in coverage through Medicare, a spousal plan, or an Insurance Exchange, rather than COBRA, the Company will pay to Executive the amount equivalent to the Company share of COBRA premiums for eighteen (18) months as if Executive had enrolled in COBRA.

Payments and benefits provided in this Section 8(d) shall be in lieu of any termination or severance payments or benefits for which the Executive may be eligible under any of the plans, policies or programs of the Company or under the Worker Adjustment Retraining Notification Act of 1988 or any similar state statute or regulation.

(e)CHANGE IN CONTROL.

(i)This Section 8(e) shall apply if the Executive’s employment by the Company is terminated (x) by the Company other than for Cause pursuant to Section 7(d) hereof, or (y) by the Executive for Good Reason, in either case, during the Employment Term and the two (2)-year period commencing upon a Change in Control. Subject to the Executive’s not engaging in a Material Covenant Violation or a Material Cooperation Violation, upon a termination described in the preceding sentence, the Executive shall receive the benefits set forth in Section 8(d)(i), (ii) and (iii), except that in lieu of receiving the Severance Amount, as applicable, in installments as contemplated under Section 8(d)(ii), the Executive shall receive a lump sum payment equal to the applicable Severance Amount, on the date of such termination; provided that to the extent that the payment of the applicable amount constitutes “nonqualified deferred compensation” for purposes of Code Section 409A, such payment shall be made on the sixtieth (60^th) day following such termination.

(ii)For purposes of this Agreement, the term “Change in Control” shall mean the consummation of the first transaction following the Hire Date, whether in a single transaction or in a series of related transactions, in which any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended) (a “Group”), (A) acquires (whether by merger, consolidation, or transfer or issuance of equity interests or otherwise) equity interests of Parent (or any surviving or resulting entity) representing more than fifty percent (50%) of the outstanding voting securities or economic value of Parent (or any surviving or resulting entity),

or (B) acquires assets constituting all or substantially all (more than eighty percent (80%)) of the assets of Parent and its subsidiaries (as determined on a consolidated basis).

(f)CODE SECTION 280G.

(i)Change in Control Prior to Publicly Traded Equity of Company. So long as the Company is described in Section 280G(b)(5)(A)(ii)(I) of the Code, in the event that any payment that is either received by the Executive or paid by the Company on the Executive’s behalf or any property, or any other benefit provided to the Executive under the Agreement or under any other plan, arrangement or agreement with the Company or any other person whose payments or benefits are treated as contingent on a change of ownership or control of the Company (or in the ownership of a substantial portion of the assets of the Company) or any person affiliated with the Company or such person (but only if such payment or other benefit is in connection with the Executive’s employment by the Company) (collectively the “Company Payments”), would be subject to the tax imposed by Section 4999 of the Code (and any similar tax that may hereafter be imposed by any taxing authority) (the “Excise Tax”), the Company shall, with respect to such Company Payments, use its reasonable best efforts to obtain a vote satisfying the requirements of Section 280G(b)(5) of the Code, such that no portion of the Company Payments will be subject to such Excise Tax. In the event that a vote satisfying the requirements of Section 280G(b)(5) of the Code is not obtained for any reason, then the Executive will be entitled to receive a portion of the Company Payments having a value equal to $1 less than three (3) times the Executive’s “base amount” (as such term is defined in Section 280G(b)(3)(A) of the Code) (the “Safe Harbor Amount”). Any reduction of the Company Payments pursuant to the foregoing shall occur in the following order: (A) any cash severance payable by reference to the Executive’s Base Salary or Annual Bonus; (B) any other cash amount payable to the Executive; (C) any benefit valued as a “parachute payment;” and (D) acceleration of vesting of any equity award.

(ii)Change in Control Upon or Following Publicly Traded Equity of Company. In the event that Company Payments become payable to the Executive during any period in which the Company is not an entity described in Section 280G(b)(5)(A)(ii)(I) of the Code, if the Company Payments will be subject to the Excise Tax, then the Executive will be entitled to receive either (A) the full amount of the Company Payments, or (B) a portion of the Company Payments having a value equal to the Safe Harbor Amount, whichever of clauses (A) and (B), after taking into account applicable federal, state, and local income taxes and the Excise Tax, results in the receipt by the Executive on an after-tax basis, of the greatest portion of the Company Payments. Any reduction of the Company Payments pursuant to the foregoing shall occur in the same manner as provided in the last sentence of Section 8(f)(i) hereof.

(iii)Accountants. Any determination required under this Section 8(f) shall be made in writing by the independent public accountants of the Company, whose determination shall be conclusive and binding for all purposes upon the Company and the Executive. For purposes of making any calculation required by this Section 8(f), such accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good-faith interpretations concerning the application of Sections 280G and 4999 of the Code; provided, however, the accountants will factor in the adverse value to the Executive of the non-competition restriction set forth in Section 10(b) in determining such calculation.

(g)OTHER OBLIGATIONS. Upon any termination of the Executive’s employment with the Company, the Executive shall promptly resign (following a request by the Company) from any other position as an officer, director or fiduciary of the Company, Parent and any Affiliate.

9.RELEASE; NO MITIGATION; NO SET-OFF. Any and all amounts payable and benefits or additional rights provided pursuant to this Agreement beyond the Accrued Benefits (other than the amount described in Section 8(a)(iii) hereof) shall only be payable if the Executive delivers to the Company and does not revoke a general release of claims in favor of the Company in substantially the form of Exhibit A attached hereto.  Such release shall be executed and delivered (and no longer subject to revocation, if applicable) within sixty (60) days following termination.  In no event shall the Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under any of the provisions of this Agreement, nor shall the amount of any payment hereunder be reduced by any compensation earned by the Executive as a result of employment by a subsequent employer (except as provided in Section 8(d)(iii) hereof). The Company’s obligations to pay the Executive amounts hereunder shall not be subject to set-off, counterclaim or recoupment of amounts owed by the Executive to the Company or any of its affiliates.

10.RESTRICTIVE COVENANTS.

(a)CONFIDENTIALITY. During the course of the Executive’s employment with the Company and its Affiliates, the Executive will learn confidential information regarding Parent and its Affiliates (the “Parent Group”). The Executive agrees that the Executive shall not, directly or indirectly, use, make available, sell, disclose or otherwise communicate to any person, other than in the course of the Executive’s assigned duties and for the benefit of the Parent Group, either during the period of the Executive’s employment or at any time thereafter, any business and technical information or trade secrets, nonpublic, proprietary or confidential information, knowledge or data relating to the Parent Group, or received from third parties subject to a duty on the Parent Group’s part to maintain the confidentiality of such information and to use it only for certain limited purposes, in each case which shall have been obtained by the Executive during the Executive’s employment by the Parent Group. The foregoing shall not apply to information that (i) was known to the public prior to its disclosure to the Executive; (ii) becomes generally known to the public subsequent to disclosure to the Executive through no wrongful act of the Executive or any representative of the Executive; or (iii) the Executive is required to disclose by applicable law, regulation or legal process (provided that the Executive provides the Company with prior notice of the contemplated disclosure and cooperates with the Company at its expense in seeking a protective order or other appropriate protection of such information). The terms and conditions of this Agreement shall remain strictly confidential, and the Executive hereby agrees not to disclose the terms and conditions hereof to any person or entity, other than immediate family members, legal advisors or personal tax or financial advisors, or prospective future employers solely for the purpose of disclosing the limitations on the Executive’s conduct imposed by the provisions of this Section 10 who, in each case, shall be instructed by the Executive to keep such information confidential.

(b)NONCOMPETITION. The Executive acknowledges that the Executive performs services of a unique nature for the Parent Group that are irreplaceable, and that the Executive’s performance of such services to a competing business will result in irreparable harm to the Parent Group. Accordingly, during the Executive’s employment hereunder and for a period of two (2) years thereafter, the Executive agrees that the Executive will not, directly or indirectly, own, manage,

operate, control, be employed by (whether as an employee, consultant, independent contractor or otherwise, and whether or not for compensation) or render services to any person, firm, corporation or other entity, in whatever form, engaged in competition with any material business of the Parent or any Affiliate or in any other material business in which the Parent or any Affiliate has taken material steps and has material plans, on or prior to the date or termination, to be engaged in on or after such date, in any locale of any country in which the Company or such Affiliate conducts business. Notwithstanding the foregoing, nothing herein shall prohibit the Executive from being a passive owner of not more than one percent (1%) of the equity securities of a publicly traded corporation engaged in a business that is in competition with Parent or any of its Affiliates, so long as the Executive has no active participation in the business of such corporation .

(c)NONSOLICITATION; NONINTERFERENCE. During the Executive’s employment with the Company and for a period of two (2) years thereafter, the Executive agrees that the Executive shall not, except in the furtherance of the Executive’s duties hereunder, directly or indirectly, individually or on behalf of any other person, firm, corporation or other entity, (i) solicit, aid or induce any customer of Parent or an Affiliate to purchase goods or services then sold by Parent or any Affiliate from another person, firm, corporation or other entity or assist or aid any other persons or entity in identifying or soliciting any such customer , (ii) solicit, aid or induce any employee, representative or agent of Parent or any Affiliate to leave such employment or retention or, in the case of employees, to accept employment with or render services to or with any other person, firm, corporation or other entity unaffiliated with Parent or any Affiliate, or hire or retain any such employee, or take any action to materially assist or aid any other person, firm, corporation or other entity in identifying, hiring or soliciting any such employee, or (iii) interfere, or aid or induce any other person or entity in interfering, with the relationship between Parent or any Affiliate and any of their respective vendors, joint venturers or licensors. An employee, representative or agent shall be deemed covered by this Section 10(c) while so employed or retained and for a period of six (6) months thereafter.  Notwithstanding the foregoing, the provisions of this Section 10(c) shall not be violated by general advertising or solicitation not specifically targeted at Parent or Affiliate-related individuals or entities.

(d)INVENTIONS.

(i)The Executive acknowledges and agrees that all ideas, methods, inventions, discoveries, improvements, work products, developments or works of authorship (“Inventions”), whether patentable or unpatentable, (A) that relate to the Executive’s work with the Parent Group, made or conceived by the Executive, solely or jointly with others, during the Employment Term, or (B) suggested by any work that the Executive performs in connection with the Parent Group, either while performing the Executive’s duties with the Parent Group or on the Executive’s own time, shall belong exclusively to the Company (or its designee), whether or not patent applications are filed thereon. The Executive will keep full and complete written records (the “Records”), in the manner prescribed by the Company, of all Inventions, and will promptly disclose all Inventions completely and in writing to the Company. The Records shall be the sole and exclusive property of the member of the Parent Group designated by Parent, and the Executive will surrender them upon the termination of the Employment Term, or upon the Company’s request. The Executive will assign to the member of the Parent Group designated by Parent the Inventions and all patents that may issue thereon in any and all countries, whether during or subsequent to the Employment Term, together with the right to file, in the Executive’s name or in the name of the member of the Parent Group designated by Parent, applications for patents and equivalent rights (the “Applications”). The Executive will, at any time

during and subsequent to the Employment Term, make such applications, sign such papers, take all rightful oaths, and perform all acts as may be requested from time to time by the Company with respect to the Inventions. The Executive will also execute assignments to the member of the Parent Group designated by Parent of the Applications, and give the member of the Parent Group designated by Parent and its attorneys all reasonable assistance (including the giving of testimony) to obtain the Inventions for the Parent Group’s benefit, all without additional compensation to the Executive from the Parent Group.

(ii)In addition, the Inventions will be deemed Work for Hire, as such term is defined under the copyright laws of the United States, on behalf of the Parent Group and the Executive agrees that the member of the Parent Group designated by Parent will be the sole owner of the Inventions, and all underlying rights therein, in all media now known or hereinafter devised, throughout the universe and in perpetuity without any further obligations to the Executive. If the Inventions, or any portion thereof, are deemed not to be Work for Hire, the Executive hereby irrevocably conveys, transfers and assigns to the member of the Parent Group designated by Parent, all rights, in all media now known or hereinafter devised, throughout the universe and in perpetuity, in and to the Inventions, including, without limitation, all of the Executive’s right, title and interest in the copyrights (and all renewals, revivals and extensions thereof) to the Inventions, including, without limitation, all rights of any kind or any nature now or hereafter recognized, including, without limitation, the unrestricted right to make modifications, adaptations and revisions to the Inventions, to exploit and allow others to exploit the Inventions and all rights to sue at law or in equity for any infringement, or other unauthorized use or conduct in derogation of the Inventions, known or unknown, prior to the date hereof, including, without limitation, the right to receive all proceeds and damages therefrom. In addition, the Executive hereby waives any so-called “moral rights” with respect to the Inventions. To the extent that the Executive has any rights in the results and proceeds of the Inventions that cannot be assigned in the manner described herein, the Executive agrees to unconditionally waive the enforcement of such rights. The Executive hereby waives any and all currently existing and future monetary rights in and to the Inventions and all patents that may issue thereon, including, without limitation, any rights that would otherwise accrue to the Executive’s benefit by virtue of the Executive being an employee of or other service provider to the Parent Group.

(e)RETURN OF COMPANY PROPERTY. On the date of the Executive’s termination of employment with the Company for any reason (or at any time prior thereto at the Company’s request), the Executive shall return all property belonging to the Company or its Affiliates (including, but not limited to, any Company-provided laptops, computers, cell phones, wireless electronic mail devices or other equipment, or documents and property belonging to the Company).  Notwithstanding anything to the contrary in this Agreement, Executive may retain his rolodex, either in electronic or paper form, in addition to copies of documents related to his compensation and benefits.

(f)REASONABLENESS OF COVENANTS. In signing this Agreement, the Executive gives Parent and the Company assurance that the Executive has carefully read and considered all of the terms and conditions of this Agreement, including the restraints imposed under this Section 10. The Executive agrees that these restraints are necessary for the reasonable and proper protection of the Company and its Affiliates and their trade secrets and confidential information and that each and every one of the restraints is reasonable in respect to subject matter, length of time and geographic area, and that these restraints, individually or in the aggregate, will not prevent the Executive from obtaining other suitable employment during the period in which the Executive is bound by the

restraints.  The Executive acknowledges that each of these covenants has a unique, very substantial and immeasurable value to the Company and its Affiliates and that the Executive has sufficient assets and skills to provide a livelihood while such covenants remain in force. The Executive further covenants that the Executive will not challenge the reasonableness or enforceability of any of the covenants set forth in this Section 10, other than in response to an attempt by the Company or an Affiliate to enforce such covenants against the Executive. It is also agreed that the Affiliates will have the right to enforce all of the Executive’s obligations to such Affiliates under this Agreement, including without limitation pursuant to this Section 10.

(g)REFORMATION. If it is determined by a court of competent jurisdiction in any state that any restriction in this Section 10 is excessive in duration or scope or is unreasonable or unenforceable under applicable law, it is the intention of the parties that such restriction may be modified or amended by the court to render it enforceable to the maximum extent permitted by the laws of that state.

(h)TOLLING. In the event of any violation of the provisions of this Section 10 , the Executive acknowledges and agrees that the post-termination restrictions contained in this Section 10 shall be extended by a period of time equal to the period of such violation, it being the intention of the parties hereto that the running of the applicable post-termination restriction period shall be tolled during any period of such violation.

(i)SURVIVAL OF PROVISIONS. The obligations contained in Sections 10 and 11 hereof shall survive the termination of the Executive’s employment with the Company and shall be fully enforceable thereafter.

11.COOPERATION. Upon the receipt of reasonable notice from the Company (including through outside counsel), the Executive agrees that while employed by the Company and thereafter (to the extent it does not materially interfere with the Executive’s employment or other business and personal activities after employment by the Company), the Executive will reasonably respond and provide information with regard to matters in which the Executive has knowledge as a result of the Executive’s employment with the Company, and will provide reasonable assistance to the Company, the Affiliates and their respective representatives in defense of all claims that may be made against the Company or the Affiliates, and will reasonably assist the Company and the Affiliates in the prosecution of all claims that may be made by the Company or the Affiliates, to the extent that such claims may relate to the period of the Executive’s employment with the Company. The Executive also agrees to promptly inform the Company (to the extent that the Executive is legally permitted to do so) if the Executive is asked to assist in any investigation of the Company or the Affiliates (or their actions), regardless of whether a lawsuit or other proceeding has then been filed against the Company or Affiliates with respect to such investigation, and shall not do so unless legally required. Upon presentation of appropriate documentation, the Company shall pay or reimburse the Executive for all reasonable out-of-pocket travel, duplicating, telephonic, counsel and other expenses incurred by the Executive in complying with this Section 11.

12.EQUITABLE RELIEF AND OTHER REMEDIES. The Executive acknowledges and agrees that the remedies at law for a breach or threatened breach of any of the provisions of Section 10 hereof or Section 11 hereof could be inadequate and, in recognition of this fact, the Executive agrees that, in the event of such a breach or threatened breach, in addition to any remedies at law, Parent and/or the Company may be entitled to seek to obtain equitable relief in the form of

specific performance, a temporary restraining order, a temporary or permanent injunction or any other equitable remedy which may then be available. In the event a court of competent jurisdiction determines that a Material Covenant Violation or a Material Cooperation Violation by the Executive has occurred, any severance being paid to the Executive pursuant to this Agreement or otherwise shall immediately cease.

13.NO ASSIGNMENTS. This Agreement is personal to each of the parties hereto. Except as provided in this Section 13 hereof, no party may assign or delegate any rights or obligations hereunder without first obtaining the written consent of the other party hereto. Parent shall assign this Agreement to any successor to all or substantially all of the business and/or assets of Parent, provided that Parent shall require such successor to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place and, as applicable, this Agreement shall inure to the benefit of Executive’s heirs and estate. As used in this Agreement, “Parent” shall mean Parent and any successor to all or substantially all of its business and/or assets, which assumes and agrees to perform the duties and obligations of Parent under this Agreement by operation of law or otherwise. In the event of a sale of the Company (or all or substantially all of its business) to an independent third party in connection with a transaction that does not constitute a Change in Control, the Company and the Executive shall assign the Company’s rights and obligations hereunder to Parent or to a mutually agreed upon direct or indirect subsidiary of Parent, and the Company shall be released from its obligations hereunder.

14.NOTICES. For purposes of this Agreement, notices and all other communications provided for in this Agreement shall be in writing and shall be deemed to have been duly given (a) on the date of delivery, if delivered by hand, (b) on the date of transmission, if delivered by confirmed facsimile or electronic mail, (c) on the first business day following the date of deposit, if delivered by guaranteed overnight delivery service, or (d) on the fourth business day following the date delivered or mailed by United States registered or certified mail, return receipt requested, postage prepaid, addressed as follows:

15.SECTION HEADINGS; INCONSISTENCY. The section headings used in this Agreement are included solely for convenience and shall not affect, or be used in connection with, the interpretation of this Agreement. In the event of any inconsistency between the terms of this Agreement (including the Exhibits hereto) and any form, award, plan or policy of the Parent Group, the terms of this Agreement shall govern and control.

16.SEVERABILITY. The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof.

17.COUNTERPARTS. This Agreement may be executed in several counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instrument.

18.INDEMNIFICATION. The Parent Group hereby agrees to indemnify the Executive and hold the Executive harmless to the fullest extent allowable under applicable law against and in respect of any and all actions, suits, proceedings, claims, demands, judgments, costs, expenses (including attorney’s fees, and the advancement of such fees subject to any legally required repayment undertaking), losses, and damages resulting from the Executive’s performance of the Executive’s duties and obligations with the Parent Group. This obligation shall survive the termination of the Executive’s employment with the Company.

19.LIABILITY INSURANCE. The Parent Group shall cover the Executive under directors’ and officers’ liability insurance both during and, while potential liability exists, after the Employment Term in the same amount and to the same extent as the Parent Group covers its other officers and directors.

20.GOVERNING LAW. This Agreement, the rights and obligations of the parties hereto, and any claims or disputes relating thereto, shall be governed by and construed in accordance

with the laws of the State of Delaware (but not including any choice of law rule thereof that would cause the laws of another jurisdiction to apply).

21.DISPUTE RESOLUTION. Each of the parties agrees that any dispute between the parties shall be resolved only in the courts of the State of Delaware or the United States District Court for the District of Delaware and the appellate courts having jurisdiction of appeals in such courts. In that context, and without limiting the generality of the foregoing, each of the parties hereto irrevocably and unconditionally (a) submits in any proceeding relating to this Agreement or the Executive’s employment by the Company or any Affiliate, or for the recognition and enforcement of any judgment in respect thereof (a “Proceeding”), to the exclusive jurisdiction of the courts of the State of Delaware, the court of the United States of America for the District of Delaware, and appellate courts having jurisdiction of appeals from any of the foregoing, and agrees that all claims in respect of any such Proceeding shall be heard and determined in such Delaware State court or, to the extent permitted by law, in such federal court, (b) consents that any such Proceeding may and shall be brought in such courts and waives any objection that the Executive or the Company may now or thereafter have to the venue or jurisdiction of any such Proceeding in any such court or that such Proceeding was brought in an inconvenient court and agrees not to plead or claim the same, (c) WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY PROCEEDING (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE EXECUTIVE’S EMPLOYMENT BY THE COMPANY OR ANY AFFILIATE OF THE COMPANY, OR THE EXECUTIVE’S OR THE COMPANY’S PERFORMANCE UNDER, OR THE ENFORCEMENT OF, THIS AGREEMENT, (d) agrees that service of process in any such Proceeding may be effected by mailing a copy of such process by registered or certified mail (or any substantially similar form of mail), postage prepaid, to such party at the Executive’s or the Company’s address as provided in Section 14 hereof, and (e) agrees that nothing in this Agreement shall affect the right to effect service of process in any other manner permitted by the laws of the State of Delaware. Each party shall be responsible for its own legal fees incurred in connection with any dispute hereunder.

22.MISCELLANEOUS. No provision of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing and signed by the Executive and such officer or director as may be designated by the Board. No waiver by either party hereto at any time of any breach by the other party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. This Agreement together with all exhibits hereto sets forth the entire agreement of the parties hereto in respect of the subject matter contained herein and supersedes any and all prior agreements or understandings between the Executive and Parent Group.

23.REPRESENTATIONS; ACTIONS BY PRIOR EMPLOYERS. The Executive represents and warrants to the Company that (a) the Executive has used the Executive’s best efforts to provide the Company with (i) each agreement with a predecessor employer which may have any bearing on the Executive’s legal right to enter into this Agreement and to perform all of the obligations on the Executive’s part to be performed hereunder in accordance with its terms, or (ii) a summary of the applicable provisions of each such agreement which the Executive may not provide to the Company due to an existing confidentiality obligation, and (b) other than the agreements referenced in the preceding clause (a), the Executive is not a party to any agreement or understanding, whether written or oral, and is not subject to any restriction (including, without limitation, any non-

competition restriction from a prior employer), which, in either case, could prevent the Executive from entering into this Agreement or performing all of the Executive’s duties and obligations hereunder. The Executive understands that the foregoing representations are a material inducement to Parent and the Company entering into this Agreement, and to the extent that either of such representations is untrue in any material respect at any time or for any reason, this Agreement shall be voidable by Parent and the Company such that the parties hereunder shall be relieved of all of their respective duties and obligations hereunder; provided that any termination of the Executive’s employment resulting from the Company exercising its rights pursuant to this sentence shall be treated as a termination of employment by the Executive without Good Reason. If any prior employer of the Executive, or any affiliate of any such prior employer, challenges the Executive’s right to enter into this Agreement and to perform all of the Executive’s obligations hereunder (whether by action against the Executive, the Company, Parent and/or an Affiliate), the Company, Parent (on behalf of itself and all Affiliates) and the Executive each agree to use their reasonable best efforts to defend against such challenge, and the Company further agrees to pay as incurred (within 10 days following the Company’s receipt of an invoice from the Executive), at any time from the Hire Date through the Executive’s remaining lifetime (or, if longer, through the 20^thanniversary of the Hire Date), all legal fees and expenses that the Executive may reasonably incur as a result of his personal defense of such challenge.

24.TAX MATTERS.

(a)WITHHOLDING. The Company may withhold from any and all amounts payable under this Agreement or otherwise such federal, foreign, state and local taxes as may be required to be withheld pursuant to any applicable law or regulation.

(b)SECTION 409A COMPLIANCE.

(i)The intent of the parties is that payments and benefits under this Agreement comply with Section 409A of the Code and the regulations and guidance promulgated thereunder (collectively “ Code Section 409A ”) and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in compliance therewith. To the extent that any provision hereof is modified in order to comply with Code Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and economic benefit to the Executive and the Company of the applicable provision without violating the provisions of Code Section 409A.  Any such modification shall require the written consent of the Executive. In no event whatsoever shall the Company be liable for any additional tax, interest or penalty that may be imposed on the Executive by Code Section 409A or damages for failing to comply with Code Section 409A; provided that the Company makes any modification reasonably requested by the Executive in accordance with the second sentence of this Section 24(b)(i).

(ii)A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Code Section 409A and, for purposes of any such provision of this Agreement, references to a “termination,” “termination of employment” or like terms shall mean “separation from service.” If the Executive is deemed on the date of termination to be a “specified employee” within the meaning of that term under Code Section 409A(a)(2)(B), then with regard to any payment or the provision of any benefit that is considered “nonqualified deferred compensation”

under Code Section 409A payable on account of a “separation from service,” such payment or benefit shall be made or provided at the date which is the earlier of (A) the expiration of the six (6)-month period measured from the date of such “separation from service” of the Executive, and (B) the date of the Executive’s death, to the extent required under Code Section 409A. Upon the expiration of the foregoing delay period, all payments and benefits delayed pursuant to this Section 24(b)(ii) (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or reimbursed to the Executive in a lump sum and all remaining payments and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein.

(iii)To the extent that reimbursements or other in-kind benefits under this Agreement constitute “nonqualified deferred compensation” for purposes of Code Section 409A, (A) all expenses or other reimbursements hereunder shall be made on or prior to the last day of the taxable year following the taxable year in which such expenses were incurred by the Executive, (B) any right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, and (C) no such reimbursement, expenses eligible for reimbursement, or in-kind benefits provided in any taxable year shall in any way affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other taxable year.

(iv)For purposes of Code Section 409A, the Executive’s right to receive installment payments pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments. Whenever a payment under this Agreement specifies a payment period with reference to a number of days, the actual date of payment within the specified period shall be within the sole discretion of the Company.

25.FURTHER ASSURANCES; PARENT GUARANTEE; DATA TRANSFER. The parties hereto shall cooperate with each other and do, or procure the doing of, all acts and things, and execute, or procure the execution of, all documents, as may reasonably be required to give full effect to this Agreement.  Parent hereby guarantees the performance of the obligations of the Company to pay all cash amounts due to the Executive pursuant to this Agreement.  In the event that the Company is unable or unwilling to pay any such amounts when due, upon notice of such non-payment received by Parent from the Executive, Parent shall immediately pay such amounts, or take any and all actions necessary to cause one or more Affiliates to pay such amounts, on behalf of the Company.  You understand that, in order for Parent Group to administer the compensation and benefits described in this Agreement, the Parent Group must collect, process and transfer certain of your personal data and consent to the same.

26.POST-TERMINATION TAX ISSUES. For a period of seven (7) years following termination of the Executive’s employment hereunder, the Company agrees to cooperate in good faith and use commercially reasonably efforts to comply with and respond to all reasonable requests from or inquiries by the Executive for assistance and information in connection with any matters or issues relating to Executive’s preparation of the Executive’s tax filings and the Executive’s response to any tax audit or investigation.  Such cooperation and assistance shall include, without limitation, making the Company’s officers, directors, employees, legal counsel, accountants and other advisors and representatives, who are familiar with the compensation determinations made by the Company relating to the Executive’s compensation, reasonably available to the Executive and the Executive’s representatives, on reasonable notice during normal business hours (in a manner so as to not interfere

with the normal business operations of the Company); provided, that the Company shall have no obligation to provide the Executive or his representatives with access to any books or records to the extent such books and records do not pertain to the preparation of the Executive’s tax filings and the Executive’s response to any tax audit or investigation and, to such extent, the Company and its representatives are entitled to withhold access to or redact any portion of such information. Notwithstanding anything to the contrary set forth in this Agreement, the Parent Group shall be required to disclose any information to, or otherwise cooperate with, the Executive (i) if doing so would reasonably be expected to violate, or be inadvisable in light of, any order, contract, fiduciary duty, applicable law or exchange regulation to which the Company or such affiliate is a party or is subject, (ii) if doing so would reasonably be expected to result in the loss of the ability to successfully assert attorney-client and work product privileges against any party, (iii) if the Parent Group, on the one hand, and the Executive, on the other hand, are adverse parties in a litigation and such information is reasonably pertinent thereto or (iv) if the Parent Group reasonably determines that such information should not be disclosed due to its competitively sensitive nature.The Parent Group may require the Executive and his representatives to enter into a confidentiality agreement or other similar agreements before providing any of the foregoing information or access.

I, Angelo Chaclas, in consideration of and subject to the performance by Trinseo LLC (together with its subsidiaries, the “ Company ”), of its obligations under the Employment Agreement, dated as of October 15, 2021 (the “ Agreement ”), do hereby release and forever discharge as of the date hereof the Company and its respective “Affiliates” (as defined in the Agreement) and all present, former and future directors, officers, employees, successors and assigns of the Company and its Affiliates and direct or indirect owners (collectively, the “ Released Parties”) to the extent provided below. The Released Parties are intended third-party beneficiaries of this General Release, and this General Release may be enforced by each of them in accordance with the terms hereof in respect of the rights granted to such Released Parties hereunder. Terms used herein but not otherwise defined shall have the meanings given to them in the Agreement.

1. I understand that any payments or benefits paid or granted to me under Section 8 of the Agreement represent, in part, consideration for signing this General Release and are not salary, wages or benefits to which I was already entitled. I understand and agree that I will not receive certain of the payments and benefits specified in Section 8 of the Agreement unless I execute this General Release and do not revoke this General Release within the time period permitted hereafter. 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.

2. Except as provided in paragraphs 4 and 5 below and except for the provisions of the Agreement which expressly survive the termination of my employment with the Company, I knowingly and voluntarily (for myself, my heirs, executors, administrators and assigns) release and forever discharge the Company and the other Released Parties from any and all claims, suits, controversies, actions, causes of action, cross-claims, counter ‑claims, demands, debts, compensatory damages, liquidated damages, punitive or exemplary damages, other damages, claims for costs and attorneys’ fees, or liabilities of any nature whatsoever in law and in equity, both past and present (through the date this General Release becomes effective and enforceable) and whether known or unknown, suspected, or claimed against the Company or any of the Released Parties which I, my spouse, or any of my heirs, executors, administrators or assigns, may have, which arise out of or are connected with my employment with, or my separation or termination from, the Company (including, but not limited to, any allegation, claim or violation, arising under: Title VII of the Civil Rights Act of 1964, as amended; the Civil Rights Act of 1991; the Age Discrimination in Employment Act of 1967, as amended (including the Older Workers Benefit Protection Act); the Equal Pay Act of 1963, as amended; the Americans with Disabilities Act of 1990; the Family and Medical Leave Act of 1993; the Worker Adjustment Retraining and Notification Act; the Employee Retirement Income Security Act of 1974; any applicable Executive Order Programs; the Fair Labor Standards Act; or their state or local counterparts; or under any other federal, state or local civil or human rights law, or under any other local, state, or federal law, regulation or ordinance; or under any public policy, contract or tort, or under common law; or arising under any policies, practices or procedures of the Company; or any claim for wrongful discharge, breach of contract, infliction of emotional distress, defamation; or any claim for costs, fees, or other expenses, including attorneys’ fees incurred in these matters) (all of the foregoing collectively referred to herein as the “ Claims ”).

3. I represent that I have made no assignment or transfer of any right, claim, demand, cause of action, or other matter covered by paragraph 2 above.

4. I agree that this General Release does not waive or release any rights or claims that I may have under the Age Discrimination in Employment Act of 1967 which arise after the date I execute this General Release. I acknowledge and agree that my separation from employment with the Company in compliance with the terms of the Agreement shall not serve as the basis for any claim or action (including, without limitation, any claim under the Age Discrimination in Employment Act of 1967).

5. I agree that I hereby waive all rights to sue or obtain equitable, remedial or punitive relief from any or all Released Parties of any kind whatsoever in respect of any Claim, including, without limitation, reinstatement, back pay, front pay, and any form of injunctive relief. Notwithstanding the above, I further acknowledge that I am not waiving and am not being required to waive any right that cannot be waived under law, including the right to file an administrative charge or participate in an administrative investigation or proceeding; provided, however, that I disclaim and waive any right to share or participate in any monetary award resulting from the prosecution of such charge or investigation or proceeding. Additionally, I am not waiving any right to the Accrued Benefits or claims for indemnity , contribution, advancement or defense as provided by and in accordance with the terms of the Company by-laws, articles of incorporation, liability insurance coverage, or applicable law.

6. In signing this General Release, I acknowledge and intend that it shall be effective as a bar to each and every one of the Claims hereinabove mentioned or implied. I expressly consent that this General Release shall be given full force and effect according to each and all of its express terms and provisions, including those relating to unknown and unsuspected Claims (notwithstanding any state or local statute that expressly limits the effectiveness of a general release of unknown, unsuspected and unanticipated Claims), if any, as well as those relating to any other Claims hereinabove mentioned or implied. I acknowledge and agree that this waiver is an essential and material term of this General Release and that without such waiver the Company would not have agreed to the terms of the Agreement. I further agree that in the event I should bring a Claim seeking damages against the Company, or in the event I should seek to recover against the Company in any Claim brought by a governmental agency on my behalf, this General Release shall serve as a complete defense to such Claims to the maximum extent permitted by law. I further agree that I am not aware of any pending claim of the type described in paragraph 2 as of the execution of this General Release.

7. I agree that neither this General Release, nor the furnishing of the consideration for this General Release, shall be deemed or construed at any time to be an admission by the Company, any Released Party or myself of any improper or unlawful conduct.

The Company agrees to disclose any such information only to any tax, legal or other counsel of the Company as required by law.

10. Any non ‑disclosure provision in this General Release does not prohibit or restrict me (or my attorney) from responding to any inquiry about this General Release or its underlying facts and circumstances by the Securities and Exchange Commission (SEC), the Financial Industry Regulatory Authority (FINRA), any other self ‑regulatory organization or any governmental entity.

11. I hereby acknowledge that Sections 8, 9, 10, 11, 12, 14, 16, 18, 19, 20, 21, 24 and 25 of the Agreement shall survive my execution of this General Release.

12. I represent that I am not aware of any claim by me other than the claims that are released by this General Release. I acknowledge that I may hereafter discover claims or facts in addition to or different than those which I now know or believe to exist with respect to the subject matter of the release set forth in paragraph 2 above and which, if known or suspected at the time of entering into this General Release, may have materially affected this General Release and my decision to enter into it.

13. Notwithstanding anything in this General Release to the contrary, this General Release shall not relinquish, diminish, or in any way affect any rights or claims arising out of any breach by the Company or by any Released Party of the Agreement after the date hereof; (b) that cannot be released as a matter of law, including my rights to COBRA, workers compensation, and unemployment insurance (the application of which shall not be contested by the Company); and/or (c) to accrued, vested benefits under any employee benefit, stock, savings, insurance, or pension plan of the Company..

14. Whenever possible, each provision of this General Release shall be interpreted in, such manner as to be effective and valid under applicable law, but if any provision of this General Release is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or any other jurisdiction, but this General Release shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

Dear Paula,

We are pleased to confirm a change in your Change of Control benefit under your employment contract with Trinseo PLC or its affiliate.  Basically, the change increases the severance amount from 18 months to 24 months provided all other conditions of this benefit are met.  More particularly, please note that the double trigger elements both still apply.

A side-by-side comparison of the change is provided below:

Current Change in Control Severance - Section 8(e)

New Change in Control Severance - Section 8(e)

(i)This Section 8(e) shall apply if the Executive’s employment by the Company is terminated (x) by the Company other than for Cause pursuant to Section 7(d) hereof, or (y) by the Executive for Good Reason, in either case, during the Employment Term and the two (2)-year period commencing upon a Change in Control. Subject to the Executive’s not engaging in a Material Covenant Violation or a Material Cooperation Violation, upon a termination described in the preceding sentence, the Executive shall receive the benefits set forth in Section 8(d)(i), (ii) and (iii), except that in lieu of receiving the Severance Amount, as applicable, in installments as contemplated under Section 8(d)(ii), the Executive shall receive a lump sum payment equal to the applicable Severance Amount, on the date of such termination; provided that to the extent that the payment of the applicable amount constitutes “nonqualified deferred compensation” for purposes of Code Section 409A, such payment shall be made on the sixtieth (60th) day following such termination.

(i)This Section 8(e) shall apply if the Executive’s employment by the Company is terminated (x) by the Company other than for Cause pursuant to Section 7(d) hereof, or (y) by the Executive for Good Reason, in either case, during the Employment Term and the two (2)-year period commencing upon a Change in Control. Subject to the Executive’s not engaging in a Material Covenant Violation or a Material Cooperation Violation, upon a termination described in the preceding sentence, the Executive shall receive the benefits set forth in Section 8(d)(i), (ii) and (iii), except that: (i) the Severance Amount shall be two (2.0) multiplied by the annual sum of the Executive’s Base Salary and Target Bonus in effect for the then-current year of termination, and (ii)  in lieu of receiving the Severance Amount, as applicable, in installments; the Executive shall receive a lump sum payment equal to the applicable Severance Amount, on the date of such termination; provided that to the extent that the payment of the applicable amount constitutes “nonqualified deferred compensation” for purposes of Code Section 409A, such payment shall be made on the sixtieth (60th) day following such termination.

By way of this letter amendment, we propose deleting current Section 8(e)(i) and replacing it with new Section 8(e)(i). There are no other changes to your employment contract.  All other terms and conditions remain unchanged.

Please return your acceptance at your earliest convenience.

9. YIELD PROTECTION INDEMNITIES

9.1 The Master Purchaser hereby agrees from time to time to indemnify the Regency Noteholder for, and to pay to it on demand, an amount equal to all amounts payable by the Regency Noteholder under and in accordance with the terms of (i) any costs, increased costs, broken funding costs or reduced rates of return incurred or suffered directly or indirectly by the Regency Noteholder of the payment of any part of any Regency Note prior to or after the maturity date thereof (including, for the avoidance of doubt relating to any Regency Noteholder Related Debt being paid prior to or after its scheduled maturity) or the failure of the Master Purchaser to issue the Regency Notes specified in the Initial Note Issue Notice or increase the principal amount of the Regency Notes as specified in an Additional Note Issue Notice; and (ii) any additional or termination cost payable to the provider of any swap, cap, collar, floor or other hedging arrangement entered into by the Regency Noteholder in connection with any Regency Noteholder Related Debt (together, “Break Costs”) provided that such Break Costs have not arisen as a direct result of the negligence, default or recklessness of the Regency Noteholder. If the Regency Noteholder is obliged to make any payment of Break Costs then it shall in good faith use reasonable endeavours to take such reasonable steps as may reasonably be open to it to mitigate or avoid the effects of such payment of Break Costs by placing any monies received on deposit until such Regency Noteholder Related Debt is due.

g. If after the date hereof, the Regency Noteholder is charged any fee, expense or increased cost pursuant to any Regency Noteholder Related Debt on account of any other party to such Regency Noteholder Related Debt having determined that the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any court, governmental authority, central bank or comparable agency or regulatory authority charged with the interpretation or administration thereof taking effect after the Swiss Funding Date, or compliance by such party with any guideline request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency or regulatory authority taking effect after the Swiss Funding Date (a “Relevant Change”), has or would have the effect of reducing the rate of return on such party’s (or its holding company’s) capital as a consequence of such party’s obligation in respect of such Regency Noteholder Related Debt, to a level below that which such party could have achieved but for such Relevant Change, then, within thirty (30) days of demand by the Regency Noteholder the Master Purchaser shall pay to the Regency Noteholder, an amount equal to each such amount charged to the Regency Noteholder pursuant to the terms of the relevant Regency Noteholder Related Debt (together, “Increased Costs”).  Notwithstanding anything herein to the contrary, (i) the Dodd-Frank Wall Street Reform and Consumer Protection Act and all requests, rules, guidelines or directives thereunder or issued in connection therewith, (ii) all requests, rules, guidelines or directives promulgated by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or any foreign regulatory authorities, in each case pursuant to Basel III; (iii) the CRR; and (iii) Directive 2013/36/EU of the

80

European Parliament and of the Council of 26 June 2013 on access to the activity of credit institutions and the prudential supervision of credit institutions and investment firms and any law or regulation which implements either of them, shall in each case be deemed to be a “Relevant Change,” regardless of the date enacted, adopted or issued.

9.2 Any demand made by the Regency Noteholder under Clause 9.1 or, as the case may be, Clause 9.2 shall be accompanied by a statement signed by a duly authorised signatory of the Regency Noteholder giving (to the extent that such information is within its possession and knowledge and that disclosure of such information would not involve the breach of any duty of confidentiality, the disclosure of any unpublished price sensitive information or the breach of any Requirement of Law owed by the Regency Noteholder to any other person) reasonable particulars of:

a. in the case of a demand under Clause 9.1, the calculation of the claim for reimbursement; and

b. in the case of a demand made under Clause 9.2, the Relevant Change and how the relevant amount has been calculated,

together with any supporting documentation.

Each amount certified by the Regency Noteholder as being due under this Clause 9 shall, in the absence of manifest error, be conclusive evidence of the amount so claimed.

9.3 Each party which is entitled to receive Increased Costs pursuant to Clause 9 shall, in consultation with the Master Purchaser, take all reasonable steps to mitigate any circumstances which would result in any Increased Costs becoming payable under or pursuant to Clause 9.

10. DEFAULT INTEREST

10.1 If any sum due and payable by the Master Purchaser, the Swiss Sellers, the Dutch Seller, the Swiss Servicers or the Dutch Servicer is not paid on the due date therefor in accordance with the provisions of the relevant Transaction Documents or if any sum due and payable by the Master Purchaser, the Swiss Sellers, the Dutch Seller, the Swiss Servicers or the Dutch Servicer under any judgment or decree of any court in connection herewith is not paid on the date of such judgment or decree, the period beginning on such due date or, as the case may be, the date of such judgment or decree and ending on the date upon which the obligation of the Master Purchaser, the relevant Swiss Seller, the Dutch Seller, the relevant Swiss Servicer or the Dutch Servicer to pay such sum (the balance thereof for the time being unpaid being herein referred to as an unpaid sum) is discharged shall be divided into successive periods, each of which (other than the first) shall start on the last day of the preceding period and the duration of each of which shall be selected by the person to whom such sum is payable.

10.2 During each such period relating thereto as is mentioned in Clause 10.1 an unpaid sum shall bear interest at the rate per annum which is the sum of two per

81

cent. and the London Interbank offered rate for deposits in US Dollars for the period for which such rate is to be determined which appears on the applicable Reuters screen or such other page as may replace the applicable Reuters screen at or about 11.00 a.m. provided that, if, for any such period, no such offered rate appears on such Reuters screen, the rate of interest applicable to such unpaid sum shall be the rate per annum at which HSBC Bank plc, was offering to prime banks in the London Interbank Market deposits in the currency in which such unpaid sum is denominated for the period for which such rate is to be determined.

10.3 Any interest which shall have accrued under Clause 10.2 in respect of an unpaid sum shall be due and payable and shall be paid by the Master Purchaser, the relevant Swiss Seller, the Dutch Seller, the relevant Swiss Servicer or the Dutch Servicer (as the case may be) at the end of the period by reference to which it is calculated or on such other dates as the Person to whom such sum is owed may specify by written notice to the Master Purchaser, the relevant Swiss Seller, the Dutch Seller, the relevant Swiss Servicer or the Dutch Servicer (as the case may be).

f. any dispute, claim, counterclaim, set off or defence (other than discharge in insolvency of the Obligor) of the Obligor to the payment of any Receivable  originated by that Swiss Seller in, or purporting to be in, the Receivables Pool (including a defence based on such Receivable or the related Contract not being a legal, valid and binding obligation of such Obligor enforceable against it in accordance with its terms), or any other

83

claim whether of the Obligor or any third party resulting from the sale of chemical products related to such Receivable or the furnishing or failure to furnish such merchandise or services or relating to collection activities with respect to such Receivable (if such collection activities were performed by that Swiss Seller or any of its Affiliates acting as Swiss Servicer);

93

may be, shall use reasonable efforts to claim any Tax Credit and, if it does so claim, shall have absolute discretion as to the extent, order and manner in which it does so but shall in no circumstances be liable to any of the Swiss Sellers, the Dutch Seller, the Swiss Servicers or the Dutch Servicer for not doing so.

12.8 After Tax Amount

In the event that any taxing authority seeks to charge to Tax any sum paid to the Master Purchaser, the Regency Noteholder, the Styron Security Trustee or the Instructing Party as a result of the indemnities contained herein then the amount so payable shall be grossed up by such amount as to ensure that after payment of the Tax so charged (and taking account of the Tax effect of any loss giving rise to the right to such an indemnity) there shall be left a sum equal to the amount that would otherwise be payable under such indemnity or obligation.

108

iii. upon the Styron Security Trustee giving written notice to the Relevant Transaction Parties that it has determined in its sole opinion, that there is no reasonable likelihood of there being any further realisations in respect of the Charged Property (whether arising from an enforcement of the Security or otherwise) which would be available to pay unpaid amounts outstanding under the Relevant Transaction Documents, the Relevant Transaction Party shall have no further claim against the Master Purchaser in respect of any such unpaid amounts and such unpaid amounts shall be extinguished and discharged in full.

d. that, in accordance with Article 9 of the EU Securitisation Regulation and Article 9 of the UK Securitisation Regulation:

111

i. it shall apply to exposures to be securitised the same sound and well-defined criteria for credit-granting which it applies to non-securitised exposures;

ii. the same clearly established processes for approving, amending, renewing and financing credits shall be applied, and has effective systems in place to apply such processes; and

f. it shall promptly provide the Regency Noteholder with such information in its possession or control or reasonably capable of being obtained by it as the Regency Noteholder may from time to time reasonably request to enable the Regency Noteholder or any provider of liquidity, credit enhancement, hedging or other facilities to comply with any applicable requirements of Article 5 of the EU Securitisation Regulation or Article 5 of the UK Securitisation Regulation and any other applicable due diligence provision or transparency provision of the EU Securitisation Regulation and the UK Securitisation Regulation as long as the provision of such information would not cause the Retention Holder to breach any applicable law or regulation;

g. it shall take such further action as may reasonably be required to ensure that the applicable provisions of the EU Securitisation Regulation and the UK Securitisation Regulation are complied with in respect of the Transaction and shall use commercially reasonable efforts to take any other action as may reasonably be required by the Cash Manager, the Master Purchaser and the Regency Noteholder to achieve such compliance by any relevant party; and

h. it shall promptly, upon the occurrence of a breach of any of its obligations under this Clause, notify the Cash Manager, the Master Purchaser and the Regency Noteholder of any such breach.

28.2 Securitisation Regulation representations

a. Each Retention Holder represents and warrants that:

a. If this Clause 30.4 applies to a Note for an Interest Period, the Relevant Interest Amount shall not be payable pursuant to Condition 4.2 (Payment of Interest) on that Note for that Interest Period and the rate of interest in respect of each relevant Note for the relevant Interest Period shall be the percentage rate per annum which is the sum of:

i. the Usage Fee; and

30.6 Changes to reference rates

Any amendment or waiver that relates to, or has the effect of, aligning the means of calculation of interest on a Compounded Rate Note and the other Transaction Documents to any recommendation of a Relevant Nominating Body which:

a. relates to the use of a RFR for that currency on a compounded basis in the international or any relevant domestic syndicated loan markets; and

STYRON Allgemeine VerkaufS- und Lieferbedingungen

I. Geltungsbereich

1. Unsere Verkäufe, Lieferungen und Leistungen (im Folgenden einheitlich: „Lieferungen“) erfolgen nur nach Maßgabe der nachstehenden Bedingungen. Sie finden Anwendung gegenüber Unternehmern, juristischen Personen des öffentlichen Rechts und öffentlich-rechtlichen Sondervermögen (Käufer). Der Käufer erklärt sich durch deren widerspruchslose Entgegennahme mit ihrer ausschließlichen Geltung für die jeweilige Lieferung sowie für alle Folgegeschäfte einverstanden. Entgegenstehende oder von unseren Bedingungen abweichende Bedingungen des Käufers erkennen wir nicht an, es sei denn, wir hätten ihrer Geltung ausdrücklich schriftlich zugestimmt. Unsere Bedingungen gelten auch dann, wenn wir in Kenntnis entgegenstehender oder von unseren Bedingungen abweichender Bedingungen des Käufers die Lieferung an den Käufer vorbehaltlos ausführen.

2. Wir behalten uns vor, unsere Allgemeinen Verkaufsbedingungen von Zeit zu Zeit zu ändern. Der Käufer erklärt sein Einverständnis mit der ausschließlichen Geltung der geänderten Bedingungen, wenn er nicht innerhalb einer Woche nach Zugang bei ihm der Geltung schriftlich widerspricht und er von uns anlässlich der Bekanntgabe der geänderten Bedingungen auf die Bedeutung seines Verhaltens besonders hingewiesen wurde.

II. Angebot, Muster, Garantien, Vertragsschluss

1. Unsere Angebote sind bezüglich Preis, Menge, Lieferfrist und Liefermöglichkeit freibleibend. Angebote können nur binnen 30 Tagen angenommen werden.

2. Die in Datenblättern, Broschüren und anderem Werbe- und Informationsmaterial enthaltenen Informationen und Daten dienen nur als Richtschnur und werden nur dann verbindlicher Vertragsinhalt, wenn wir dem ausdrücklich schriftlich zugestimmt haben.

3. Eigenschaften von Mustern und Proben sind nur dann verbindlich, wenn dies ausdrücklich vereinbart wurde.

4. Beschaffenheits- und Haltbarkeitsangaben gelten nur dann als Garantien, wenn sie ausdrücklich als solche bezeichnet werden. Dasselbe gilt für die Übernahme eines Beschaffungsrisikos.

5. Der Vertrag ist erst dann für uns verbindlich, wenn wir die Auftragsbestätigung schriftlich erteilen. Mündliche Abreden bedürfen der schriftlichen Bestätigung durch uns.

III.Preise, Zahlung, Verzug, Beendigung bei Insolvenzantrag

1. Die Preise verstehen sich ausschließlich gesetzlicher Mehrwertsteuer, äußerer Verpackung und Versandkosten (ab Werk).

2. Alle Preise beruhen auf den Kostenfaktoren im Zeitpunkt des Vertragsschlusses bzw. der Auftragsbestätigung. Treten danach wesentliche Erhöhungen der Kosten für Rohstoffe, Energie, Frachten oder Verpackungsmaterial bei uns oder unserem Lieferanten ein und führen diese zu einer wesentlichen Erhöhung unserer Einkaufspreise oder Selbstkosten, so sind wir berechtigt, unverzüglich mit dem Käufer Verhandlungen über eine Preisanpassung zu verlangen. Kommt innerhalb angemessener Frist eine Übereinkunft nicht zustande, so sind wir bezüglich noch ausstehender Lieferungen von unserer Lieferpflicht entbunden.

3. Unsere Rechnungen sind innerhalb der vereinbarten Zahlungsfrist zu bezahlen, spätestens 30 Tage ab Rechnungsdatum .

Maßgebend für die Einhaltung von Zahlungsfristen ist der Eingang der Zahlung auf unseren Konten. Schecks werden nur zahlungshalber angenommen. Anfallende Spesen gehen zu Lasten des Käufers.

4. Bei Zahlungsverzug werden Zinsen in Höhe von 8 Prozentpunkten jährlich über dem jeweiligen Basiszinssatz (§ 247 BGB) fällig. Der Nachweis eines weitergehenden Verzugsschadens bleibt vorbehalten.

5. Wir sind zur Erfüllung des Vertrages solange nicht verpflichtet, wie der Käufer seinen Pflichten auch aus anderen Verträgen mit uns nicht vereinbarungsgemäß nachkommt, insbesondere fällige Rechnungen nicht bezahlt.

6. Der Käufer kann nur mit solchen Ansprüchen aufrechnen oder ihretwegen die Zahlung zurückhalten, die schriftlich unbestritten oder rechtskräftig festgestellt sind.

7. Wir sind berechtigt, ausstehende Lieferungen nur gegen Vorkasse durchzuführen oder von der Stellung einer Sicherheit abhängig zu machen, wenn der Käufer mit vereinbarten Zahlungszielen auch nach Ablauf einer angemessenen Nachfrist in Verzug ist oder Umstände vorliegen, die bei Anlegung banküblicher Maßstäbe Zweifel an der Zahlungsfähigkeit des Käufers begründen. In diesen Fällen sind wir darüber hinaus berechtigt, alle Forderungen gegen den Käufer aus der Geschäftsverbindung sofort fällig zu stellen.

8. Dieser Kaufvertrag endet automatisch, wenn ein Antrag auf Eröffnung eines Insolvenzverfahrens über das Vermögen des Käufers gestellt wird und das zuständige Insolvenzgericht daraufhin Sicherungsmaßnahmen gemäß §§ 21, 22 InsO anordnet.

IV. Lieferung und Lieferzeiten, Verpackung, Gefahrübergang

1. Für Art und Umfang der Lieferung ist unsere schriftliche Auftragsbestätigung maßgebend. Wir sind zu Teillieferungen berechtigt, soweit sie für den Käufer zumutbar sind.

2. Lieferfristen gelten nur annähernd, sofern sie nicht ausdrücklich schriftlich als verbindlich zugesagt wurden. Die Lieferzeit beginnt mit der Absendung unserer Auftragsbestätigung, jedoch nicht vor Klärung aller für die Durchführung des Vertrages wesentlichen Fragen im Zusammenhang mit vom Käufer vorzunehmenden Handlungen. Insbesondere beginnt die Lieferzeit nicht, bevor wir vom Käufer oder dessen Vertreter alle für die Lieferung benötigten Informationen erhalten bzw. bevor der Käufer nachweist, dass er, soweit erforderlich, vertragsgemäß ein Akkreditiv eröffnet oder eine Vorauszahlung bzw. Sicherheit geleistet hat.

167

3. Die Lieferfrist ist eingehalten, wenn bis zu ihrem Ablauf der Leistungsgegenstand unser Werk verlassen hat oder unsere Lieferbereitschaft mitgeteilt ist.

4. Alle Fälle von höherer Gewalt, Streik, Aussperrung, unzureichender Material-, Rohstoff- oder Energieversorgung, Mangel an Transportmöglichkeiten und andere ähnliche Ereignisse oder Ursachen außerhalb unseres Einwirkungsbereiches entbinden uns für die Zeitdauer und den Umfang solcher Hindernisse von unserer Verpflichtung zur Erfüllung des Vertrages. Dies gilt auch, wenn diese Umstände bei unseren Zulieferern eintreten. Die vorbezeichneten Umstände sind auch dann von uns nicht zu vertreten, wenn sie während eines bereits vorliegenden Verzuges eintreten. Beginn und Ende solcher Hinderungsgründe teilen wir dem Käufer baldmöglichst schriftlich mit.

5. Falls Lieferung einer Gesamtmenge in mehreren Abrufen vereinbart ist, hat der Käufer die Einzellieferungen gleichmäßig über das Kalenderjahr zu verteilen. Falls in einem Kalendermonat mehr als 10% des jährlichen Lieferumfangs abgerufen werden soll, bedarf dies unserer vorherigen, schriftlichen Zustimmung.

6. Wir bestimmen die Art der Verpackung und des Versands.

7. Die Gefahr geht spätestens mit der Absendung des Leistungsgegenstandes auf den Käufer über, und zwar auch dann, wenn wir zusätzliche Leistungen wie Verladung, Transport oder Entladung übernommen haben. Verzögert sich die Lieferung infolge von Umständen, die der Käufer zu vertreten hat, geht die Preisgefahr am Tag der Mitteilung der Lieferbereitschaft auf ihn über. Auf Verlangen des Käufers versichern wir die jeweilige Sendung auf seine Kosten gegen Diebstahl, Bruch-, Transport-, Feuer- und Wasserschäden.

8. Beanstandungen wegen Transportverzögerungen, Fehlmeldungen oder Transportschäden hat der Käufer unverzüglich gegenüber unserem Spediteur und Frachtführer geltend zu machen und uns dies unverzüglich mitzuteilen.

9. Wir sind auch nicht verpflichtet, auf Geheiß des Käufers an Dritte zu liefern.

V. Mängelansprüche, Pflichten des Käufers bei Mängelanzeige durch seine Kunden, Aufwendungsersatz, Haftung

1. Mängelansprüche des Käufers setzen voraus, dass er seinen gesetzlichen Untersuchungs- und Rügepflichten ordnungsgemäß nachgekommen ist. Bei offensichtlicher Mangelhaftigkeit oder Unvollständigkeit der Ware sind uns die Beanstandungen innerhalb von 2 Wochen nach Ankunft der Lieferung am Bestimmungsort schriftlich unter genauer Bezeichnung des Fehlers und der Auftrags- bzw. Rechnungsnummer anzuzeigen. Auf unsere Aufforderung sind die auf Lieferung bezogenen Dokumente, Muster, und/oder die fehlerhafte Ware an uns zurückzusenden. Ansprüche des Käufers wegen Mangelhaftigkeit oder Unvollständigkeit der Lieferung sind ausgeschlossen, wenn er dieser Verpflichtung nicht nachkommt.  

2. Sollte die Ware Mängel aufweisen, können wir nach unserer Wahl als Nacherfüllung die Mängel beseitigen oder mangelfreien Ersatz leisten. Erst wenn dies wiederholt fehlgeschlagen oder unzumutbar sein sollte und es sich nicht nur um unerhebliche Mängel handelt, ist der Käufer nach Maßgabe der gesetzlichen Vorschriften zum Rücktritt oder zur Minderung berechtigt. § 478 BGB bleibt unberührt. Schadensersatzansprüche stehen dem Käufer nach Maßgabe von Ziffer V.6. zu.

Hinsichtlich etwaiger Ersatzlieferungen und Nachbesserungsarbeiten gilt eine Verjährungsfrist von 3 Monaten ab Ablieferung bzw. Ausführung, die aber mindestens bis zum Ablauf der Verjährungsfrist für Mängelansprüche unserer ursprünglichen Leistung läuft (vgl. Ziffer V.9.).  

3. Der Käufer hat uns unverzüglich über jede Mängelanzeige seines Kunden in Bezug auf unsere Liefergegenstände zu informieren. Kommt der Käufer dieser Verpflichtung nicht nach, hat er keine Mängelansprüche gegen uns, auch keinen Aufwendungsersatzanspruch gemäß § 478 BGB. Der Käufer hat zudem Beweise in geeigneter Form zu sichern und uns auf Verlangen Gelegenheit zur Überprüfung zu geben.

4. Nicht von uns vorab autorisierte Werbeaussagen des Käufers in seinen Werbematerialien oder gegenüber seinen Kunden begründen keine Mängelansprüche gegen uns.

5.Mängelansprüche bestehen nicht bei nur unerheblicher Abweichung von der vereinbarten Beschaffenheit und/ oder bei nur unerheblicher Beeinträchtigung der Brauchbarkeit. Wir haften nicht für die Eignung der Ware für die vom Käufer beabsichtigten Zwecke, es sei denn, der beabsichtigte Zweck ist schriftlicher Vertragsinhalt.

6.Wir haften unbeschränkt nach dem Produkthaftungsgesetz, in Fällen der ausdrücklichen Übernahme einer Garantie oder eines Beschaffungsrisikos sowie wegen vorsätzlicher oder grob fahrlässiger Pflichtverletzungen. Ebenso haften wir unbeschränkt bei vorsätzlicher oder fahrlässiger Verletzung des Lebens, des Körpers oder der Gesundheit. Für leicht fahrlässig verursachte Sach- und Vermögensschäden haften wir nur im Falle der Verletzung solcher Pflichten, deren Erfüllung die ordnungsgemäße Durchführung des Vertrags überhaupt erst ermöglicht und auf deren Erfüllung der Käufer in besonderem Maße vertrauen darf („wesentliche Vertragspflichten), jedoch begrenzt auf den bei Vertragsschluss voraussehbaren, vertragstypischen Schaden.

7.Ansprüche auf Ersatz von Schäden aller Art, die infolge unsachgemäßer Behandlung, Veränderung, Montage und/oder Bedienung der Liefergegenstände oder durch fehlerhafte Beratung oder Einweisung durch den Käufer entstehen, sind ausgeschlossen, es sei denn, wir haben sie zu vertreten. Zudem trägt der Käufer die volle Verantwortung für die Verwendung eines auf seinen Wunsch auf der Ware erscheinenden Designs, Warenzeichens oder Handelsnamens.

8.Ist der Käufer berechtigt, Schadensersatz statt der Leistung zu verlangen oder vom Vertrag zurückzutreten, so muss er sich auf unser Verlangen binnen angemessener Frist erklären, ob und wie er von diesen Rechten Gebrauch machen wird. Erklärt er sich nicht fristgerecht oder besteht er auf der Leistung, ist er zur Ausübung dieser Rechte erst nach fruchtlosem Ablauf einer weiteren angemessenen Nachfrist berechtigt.

9.Ansprüche wegen Mängeln verjähren in 12 Monaten ab Gefahrübergang. Für Rechtsmängel gilt Entsprechendes. Bei vorsätzlichen Pflichtverletzungen, bei Ansprüchen aus unerlaubter Handlung, beim Fehlen garantierter Eigenschaften, bei Übernahme von Beschaffungsrisiken sowie bei Verletzung von Personen gelten die gesetzlichen Verjährungsfristen. Ist die Leistung für ein Bauwerk bestimmt und hat sie dessen Mangelhaftigkeit verursacht, beträgt die Verjährungsfrist für Mängelansprüche 5 Jahre. §§ 438 Abs. 3, 479 und 634 a Abs. 3 BGB bleiben unberührt.

168

10.Falls dem Käufer wegen einer von uns zu vertretenden Verzögerung ein Schaden entsteht, kann er für jede volle Woche der Verzögerung 0,5%, insgesamt aber höchstens 5% vom Rechnungspreis desjenigen Teils der Leistung verlangen, der infolge der Verspätung nicht rechtzeitig oder nicht vertragsgemäß benutzt werden kann.

11.Eine weitergehende Haftung auf Schadensersatz als in den vorstehenden Absätzen dieser Ziffer V. vorgesehen, ist - ohne Rücksicht auf die Rechtsnatur des geltend gemachten Anspruchs - ausgeschlossen.

12.Die vorstehenden Haftungsbeschränkungen gelten nach Grund und Höhe auch zugunsten unserer gesetzlichen Vertreter, Mitarbeiter und sonstigen Erfüllungs- und/oder Verrichtungsgehilfen.

VI.Eigentumsvorbehalt

1. Wir behalten uns das Eigentum an allen gelieferten Waren vor, bis der Käufer sämtliche derzeitigen und künftigen Verpflichtungen aus der Geschäftsverbindung mit uns vollständig erfüllt hat. Dies gilt auch dann, wenn Zahlungen auf besonders bezeichnete Forderungen geleistet werden. Bei laufender Rechnung gilt die Vorbehaltsware als Sicherheit für die Saldoforderung.

2. Be- und Verarbeitung der Vorbehaltsware erfolgen für uns als Hersteller im Sinne des § 950 BGB, ohne uns zu verpflichten. Die be-/verarbeitete Ware gilt als Vorbehaltsware im Sinne dieser Bedingungen. Wird die Vorbehaltsware mit anderen, uns nicht gehörenden Gegenständen verarbeitet oder untrennbar vermengt/verbunden, so erwerben wir das Miteigentum an der neuen Sache im Verhältnis des Rechnungswertes der Vorbehaltsware zum Rechnungswert der anderen verwendeten Gegenstände zum Zeitpunkt der Verarbeitung oder Vermengung/Verbindung. Wird die Vorbehaltsware mit anderen, uns nicht gehörenden Gegenständen zu einer einheitlichen Sache verbunden oder untrennbar vermengt und ist diese Sache als Hauptsache anzusehen, so überträgt uns der Käufer hiermit anteilmäßig Miteigentum, soweit die Hauptsache ihm gehört. Der Käufer verwahrt das so entstandene Eigentum unentgeltlich für uns mit.

3. Der Käufer ist bis zu unserem Widerruf, der jederzeit und ohne besondere Begründung zulässig ist, berechtigt, die Vorbehaltsware im ordentlichen Geschäftsgang weiterzuveräußern, weiterzuverarbeiten oder umzubilden. Als Weiterveräußerung in diesem Sinne gilt auch der Einbau in Grund und Boden oder in mit Gebäuden verbundene Anlagen oder die Verwendung zur Erfüllung sonstiger Verträge.

Der Käufer tritt uns für den Fall der Weiterveräußerung bereits hiermit seine aus einer solchen Veräußerung entstehende Kaufpreisforderung gegen den Kunden ab. Wird die Vorbehaltsware vom Käufer zusammen mit anderen, nicht von uns gelieferten Sachen veräußert, so gilt die Abtretung nur in Höhe der in unserer Rechnung genannten Werte der jeweils veräußerten Vorbehaltsware. Bei der Weiterveräußerung von Gegenständen, an denen wir gemäß Ziffer VI.2. Miteigentumsanteile haben, gilt die Abtretung in Höhe dieser Miteigentumsanteile. Die abgetretenen Forderungen dienen in demselben Umfang zur Sicherheit wie die Vorbehaltsware.

Wird die abgetretene Forderung in eine laufende Rechnung aufgenommen, so tritt der Käufer bereits jetzt einen der Höhe nach dieser Forderung entsprechenden Saldo aus dem Kontokorrent an uns ab.

Der Käufer ist bis zu unserem Widerruf, der jederzeit und ohne besondere Begründung zulässig ist, berechtigt, die uns abgetretene Forderung einzuziehen. Er ist auf unser Verlangen verpflichtet, seinen Kunden die Vorausabtretung an uns anzuzeigen und uns die zur Geltendmachung der Forderung erforderlichen Auskünfte und Unterlagen zur Verfügung zu stellen.

4. Übersteigt der Wert der für uns bestehenden Sicherheiten unsere Forderungen insgesamt um mehr als 10%, geben wir auf Verlangen des Käufers entsprechende Sicherheiten nach unserer Wahl frei.

5. Zu anderen Verfügungen über die Vorbehaltsware (Verpfändungen, Sicherungsübereignungen) oder anderen Abtretungen der in Ziffer VI.3. genannten Forderungen ist der Käufer nicht berechtigt. Im Falle von Pfändungen oder Beschlagnahmen der Vorbehaltsware hat der Käufer auf unser Eigentum hinzuweisen und uns unverzüglich zu informieren.

6. Der Käufer ist verpflichtet, die Vorbehaltsware gegen alle üblichen Risiken, insbesondere gegen Feuer, Einbruchs- und Wassergefahren auf eigene Kosten angemessen zu versichern, sie pfleglich zu behandeln und sie ordnungsgemäß zu lagern.

7. Ist der Käufer mit der Zahlung von mindestens zwei Kaufpreisraten ganz oder teilweise in Zahlungsverzug, sind wir nach erfolglosem Ablauf einer von uns gesetzten Nachfrist auch dann zur Rücknahme der Vorbehaltsware berechtigt, wenn wir nicht vom Vertrag zurückgetreten sind.

VII.Leistung durch verbundene Unternehmen

Auf unser Verlangen kann jede unserer vertraglichen Verpflichtungen durch ein anderes Unternehmen des Konzerns Trinseo S.A. (Luxemburg) erfüllt werden. Die berechtigten Interessen des Käufers sind dabei angemessen zu berücksichtigen. Solange die Leistung gleichwertig ist, gelten die betreffenden vertraglichen Verpflichtungen als erfüllt.

NOTE 1—BASIS OF PRESENTATION

The unaudited interim condensed consolidated financial statements of Trinseo PLC and its subsidiaries (the “Company”) as of and for the periods ended March 31, 2023 and 2022 were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and reflect all adjustments, consisting only of normal recurring adjustments, which, in the opinion of management, are considered necessary for the fair statement of the results for the periods presented. Because they cover interim periods, the statements and related notes to the financial statements do not include all disclosures normally provided in annual financial statements, and therefore, these statements should be read in conjunction with the 2022 audited consolidated financial statements included within the Company’s Annual Report on Form 10-K (“Annual Report”) filed with the Securities and Exchange Commission (“SEC”) on February 27, 2023.

Acquisition of Heathland B.V.

On January 3, 2022, the Company completed the acquisition of Heathland B.V. (“Heathland”) from Heathland Holding B.V. (“Heathland Holding”), through the purchase of all issued and outstanding shares (the “Heathland Acquisition”). Heathland is a leading collector and recycler of post-consumer and post-industrial plastic wastes in Europe. The total purchase price consideration is estimated to be $29.3 million, including an initial cash purchase price of $22.9 million which was paid during the three months ended March 31, 2022, as well as $6.4 million of contingent cash consideration, representing the fair value of certain earn-out payments. The maximum amount of potential earn-out payments is $6.8 million, which will become payable to Heathland Holding as and when the related performance milestones or thresholds are achieved over the three-year period following the date of acquisition. Heathland results are included within the Plastics Solution segment. The Company allocated the purchase price of the acquisition to identifiable assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. Refer to the Annual Report for further information.

In February 2023, the Company delivered the first year earn-out to Heathland Holding based on its first related performance milestones or threshold in the amount of $1.2 million.

(1) This caption does not include deferred financing fees related to the Company’s revolving facilities, which are included within “Deferred charges and other assets” on the condensed consolidated balance sheets.

(2) As of March 31, 2023, under the 2026 Revolving Facility, the Company had a capacity of $375.0 million and $22.0 million outstanding letters of credit. As of March 31, 2023, the Company had funds available for borrowing of $100.5 million (net of the applicable $12.0 million outstanding letters of credit as defined in the secured credit agreement), which reflects the borrowing limit imposed by the springing covenant. The springing covenant applies when 30% or more of the 2026 Revolving Facility’s capacity is drawn which then requires the Company to meet a first lien net leverage ratio (as defined in the secured credit agreement) not to exceed 3.50x at the end of each financial quarter. As of March 31, 2023, the first lien net leverage ratio was 4.85x and the outstanding borrowings did not exceed the 30% threshold. Additionally, the Company is required to pay a quarterly commitment fee in respect of any unused commitments under this facility equal to 0.375% per annum.

(3) As of March 31, 2023, this facility had a borrowing capacity of $150.0 million, and the Company had approximately $150.0 million of accounts receivable available to support this facility, based on the pool of eligible accounts receivable.

Balance at March 31, 2023	$	351.5	$	15.1	$	43.3	$	4.3	$	—	$	—	$	414.2

As a result of the Company’s fourth quarter 2022 impairment testing, an impairment charge was taken for the PMMA business and Aristech Surfaces reporting units primarily due to the continuation of the challenging macroeconomic environment experienced in 2022 into the fourth quarter of 2022, including significantly lower demand

for building & construction and wellness applications, which led to lower operating results including slower growth projections, and a prolonged drop in market capitalization, as well as an increase in the weighted average cost of capital. This goodwill may be at risk for future impairment due to the remaining fair value being equal to carrying value as a result of the recorded impairment. While the challenging macroeconomic environment has continued to impact these businesses in the first quarter of 2023, the Company performed qualitative analyses over this goodwill, including consideration of current and estimated future financial results of the related businesses, general and industry-specific economic conditions, changes in reporting unit carrying values and potential changes to the assumptions used in the previous fair value calculations. Based on these analyses, the Company has not identified any triggering events since the fourth quarter of 2022 impairment test indicating that is more likely than not that goodwill is impaired. Should these conditions persist, or other events occur indicating that the estimated future cash flows of these businesses have declined, the Company may be required to record future non-cash impairment charges related to goodwill.

As of March 31, 2023 and December 31, 2022, the reported balance of goodwill included accumulated impairment losses of $297.1 million in the Engineered Materials segment.

Derivative Instruments

Derivative Instruments

NOTE 10—DERIVATIVE INSTRUMENTS

The Company’s ongoing business operations expose it to various risks, including fluctuating foreign exchange rates, interest rate risk, and commodity price risk, in particular natural gas. To manage these risks, the Company periodically enters into derivative financial instruments, such as foreign exchange forward contracts, interest rate swap agreements, and commodity swaps agreements, forward contracts, or options. The Company does not hold or enter into financial instruments for trading or speculative purposes. All derivatives are recorded on the condensed consolidated balance sheets at fair value.

Foreign Exchange Forward Contracts

Certain subsidiaries have assets and liabilities denominated in currencies other than their respective functional currencies, which creates foreign exchange risk. The Company’s principal strategy in managing its exposure to changes in foreign currency exchange rates is to naturally hedge the foreign currency-denominated liabilities on its balance sheet against corresponding assets of the same currency, such that any changes in liabilities due to fluctuations in exchange rates are offset by changes in their corresponding foreign currency assets. In order to further reduce this exposure, the Company also uses foreign exchange forward contracts to economically hedge the impact of the variability in exchange rates on assets and liabilities denominated in certain foreign currencies. These derivative contracts are not designated for hedge accounting treatment.

As of March 31, 2023, the Company had open foreign exchange forward contracts with a notional U.S. dollar equivalent absolute value of $657.5 million. The following table displays the notional amounts of the most significant net foreign exchange hedge positions outstanding as of March 31, 2023:

	March 31,
Buy / (Sell)	2023
Euro	$	(520.9)
Chinese Yuan	$	(48.4)
South Korean Won	$	(21.8)
Swiss Franc	$	(19.6)
Swedish Krona	$	14.7

Open foreign exchange forward contracts as of March 31, 2023 had maturities occurring over a period of two months.

Foreign Exchange Cash Flow Hedges

The Company also enters into forward contracts, as deemed appropriate, with the objective of managing the currency risk associated with forecasted U.S. dollar-denominated raw materials purchases by one of its subsidiaries whose functional currency is the euro. By entering into these forward contracts, which are designated as cash flow

hedges, the Company buys a designated amount of U.S. dollars and sells euros at the prevailing market rate to mitigate the risk associated with the fluctuations in the euro-to-U.S. dollar foreign currency exchange rates. The qualifying hedge contracts are marked-to-market at each reporting date and any unrealized gains or losses are included in Accumulated Other Comprehensive Income (“AOCI”) to the extent effective, and reclassified to cost of sales in the period during which the transaction affects earnings or it becomes probable that the forecasted transaction will not occur.

The Company had no open foreign exchange cash flow hedges as of March 31, 2023.

Commodity Cash Flow Hedges & Commodity Economic Hedges

The Company purchases certain commodities, primarily natural gas, to operate facilities and generate heat and steam for various manufacturing processes, which purchases are subject to price volatility. In order to manage the risk of price fluctuations associated with these commodity purchases, as deemed appropriate, the Company may enter into commodity swaps, forward contracts, or options. As of March 31, 2023, the Company had open commodity swap agreements, which effectively convert a portion of its natural gas costs into a fixed rate obligation. These commodity derivatives are designated as cash flow hedges, and as such, the contracts are marked-to-market at each reporting date and any unrealized gains or losses are included in AOCI to the extent effective, and reclassified to cost of sales in the period during which the transaction affects earnings or it becomes probable that the forecasted transaction will not occur.

Open commodity cash flow hedges as of March 31, 2023 had maturities occurring over a period of 21 months and had a notional value of approximately 964 thousand megawatt hours of natural gas purchases.

The Company may also enter into certain commodity swap agreements to economically hedge the impact of these price fluctuations, which are not designated for hedge accounting treatment. Open commodity economic hedges as of March 31, 2023 had maturities occurring over a period of 24 months and had a notional value of approximately 895 thousand megawatt hours of natural gas purchases.

Interest Rate Swaps

On September 6, 2017, the Company issued the 2024 Term Loan B, which currently bears an interest rate of LIBOR plus 2.00%, subject to a 0.00% LIBOR floor. In order to reduce the variability in interest payments associated with the Company’s variable rate debt, during 2017 the Company entered into certain interest rate swap agreements to convert a portion of these variable rate borrowings into a fixed rate obligation. These interest rate swap agreements are designated as cash flow hedges, and as such, the contracts are marked-to-market at each reporting date and any unrealized gains or losses are included in AOCI to the extent effective, and reclassified to interest expense in the period during which the transaction affects earnings or it becomes probable that the forecasted transaction will not occur. Under the terms of the swap agreements, with a net notional U.S. dollar equivalent of $200.0 million and an effective date of September 29, 2017, the Company was required to pay the counterparties a stream of fixed interest payments at a rate of 1.81%, and in turn, receives variable interest payments based on 1-month LIBOR from the counterparties. These interest rate swap agreements matured in September 2022, and the Company has no remaining open interest rate swap agreements.

Net Investment Hedge

The Company accounts for its cross currency swaps (“CCS”) under the spot method, meaning that changes in the fair value of the hedge included in the assessment of effectiveness (changes due to spot foreign exchange rates) are recorded within AOCI, where they remain until either the sale or substantially complete liquidation of the subsidiary subject to the hedge. Additionally, the initial value of any component excluded from the assessment of effectiveness is recognized in income using a systematic and rational method over the life of the hedging instrument and any difference between the change in the fair value of the excluded component and amounts recognized in income under that systematic and rational method is recognized in AOCI. When applicable, the Company amortizes any initial excluded component value of a CCS as a reduction of “Interest expense, net” in the condensed consolidated statements of operations using the straight-line method over the remaining term of the related CCS. Additionally, interest receipts and payments are accrued under the terms of the Company’s CCS and are recognized within “Interest expense, net” in the condensed consolidated statements of operations.

The Company entered into a CCS arrangement (the “2017 CCS”) on September 1, 2017, swapping U.S. dollar principal and interest payments of $500.0 million at an interest rate of 5.375% on its 2025 Senior Notes for euro-denominated payments of €420.0 million at a weighted average interest rate of 3.45% for approximately five years. On

February 26, 2020, the Company settled its 2017 CCS and replaced it with a new CCS arrangement (the “2020 CCS”) that carried substantially the same terms as the 2017 CCS. Under the 2020 CCS, the Company notionally exchanged $500.0 million at an interest rate of 5.375% for €459.3 million at a weighted average interest rate of 3.672% for approximately 2.7 years, with a final maturity of November 3, 2022. The cash flows under the 2020 CCS are aligned with the Company’s principal and interest obligations on its 5.375% 2025 Senior Notes. Refer to the Annual Report for further information.

On April 7, 2022, the Company settled its existing 2020 CCS, which were set to mature in November 2022. Upon settlement of the 2020 CCS, the Company realized net cash proceeds of $1.9 million.

Fair Value Measurements

NOTE 11—FAIR VALUE MEASUREMENTS

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities measured at fair value are classified using the following hierarchy, which is based upon the transparency of inputs to the valuation as of the measurement date.

Level 1—Valuation is based upon quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2—Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

Level 3—Valuation is based upon other unobservable inputs that are significant to the fair value measurement.

The following table summarizes the basis used to measure certain assets and liabilities at fair value on a recurring basis in the condensed consolidated balance sheets as of March 31, 2023 and December 31, 2022:

The Company uses an income approach to value its derivative instruments, utilizing discounted cash flow techniques, considering the terms of the contract and observable market information available as of the reporting date, such as interest rate yield curves and currency spot and forward rates. Significant inputs to the valuation for these derivative instruments are obtained from broker quotations or from listed or over-the-counter market data, and are classified as Level 2 in the fair value hierarchy.

Nonrecurring Fair Value Measurements

The Company measured certain financial assets at fair value on a nonrecurring basis during the year ended December 31, 2022, which were still held as of March 31, 2023. These financial assets represent the Company’s styrene monomer assets in Boehlen, Germany, which it continued to operate until the fourth quarter of 2022 when the Company decided to close this plant in connection with the asset restructuring plan. Refer to Note 17 for further information. These assets were measured at fair value using underlying fixed asset records in conjunction with the use of industry experience and available market data, which are classified as Level 3 significant unobservable inputs in the fair value hierarchy. During the three months ended March 31, 2023, the Company recorded additional impairment charges of $0.3 million related to capital expenditures at the Boehlen styrene monomer facility that it determined to be impaired, which are also included within “Impairment and other charges” on the condensed consolidated statements of operations. Refer to the Company’s Annual Report for further information. As of March 31, 2023 and December 31, 2022, the value of the Boehlen styrene monomer assets are recorded at $3.2 million within the Company’s condensed consolidated balance sheets herein.

There were no other financial assets or liabilities measured at fair value on a nonrecurring basis as of December 31, 2022.

Fair Value of Debt Instruments

The following table presents the estimated fair value of the Company’s outstanding debt not carried at fair value as of March 31, 2023 and December 31, 2022:

Provision For Income Taxes

NOTE 12—PROVISION FOR INCOME TAXES

	Three Months Ended
	March 31,
	2023			2022
Effective income tax rate		25.4	%		56.9	%

Benefit from income taxes for the three months ended March 31, 2023 totaled $16.7 million, resulting in an effective tax rate of 25.4%. Provision for income taxes for the three months ended March 31, 2022 totaled $22.6 million, resulting in an effective tax rate of 56.9%.

The most significant driver of the decrease in the effective income tax rate for the three months ended March 31, 2023 compared to the prior year was the change in the Company’s forecasted jurisdictional mix of earnings, where income expected to be generated in higher rate jurisdictions exceeds income expected to be generated in lower rate jurisdictions, partially offset by losses not anticipated to provide a tax benefit.

The effective income tax rate for the three months ended March 31, 2022 was primarily impacted by a $35.6 million charge related to the European Commission request for information, as described within Note 13 in the condensed consolidated financial statements, for which the Company estimates no tax benefit.

Commitments and Contingencies

NOTE 13—COMMITMENTS AND CONTINGENCIES

Environmental Matters

Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law, existing technologies and other information. Pursuant to the terms of the agreement associated with the Company’s formation, the pre-closing environmental liabilities were retained by Dow, and Dow agreed, subject to temporal, monetary, and other limitations to indemnify the Company from and against environmental liabilities incurred or relating to the predecessor periods. Other than certain immaterial environmental liabilities assumed as part of the PMMA Acquisition and the Aristech Surfaces Acquisition, no material environmental claims have been asserted against the Company, and the Company does not have any material accrued obligations for any Superfund Sites. As of March 31, 2023 and December 31, 2022, the Company had $3.5 million of accrued obligations for environmental remediation or restoration costs, which were recorded at fair value within the opening balance sheets of the PMMA business and Aristech Surfaces during 2021.

On March 24, 2023, due to equipment failure at the Bristol, Pennsylvania facility, operated by our wholly-owned subsidiary, Altuglas LLC, an accidental release of a latex emulsion product occurred, which ultimately flowed into a local waterway (the “Bristol Spill”). We reported the event and cooperated closely with local, state, and federal authorities on the response activities. Water sampling conducted by the authorities did not detect site-related material in the waterway. See “Litigation Matters” below for information on environmental proceedings related to this incident. In the event of one or more adverse determinations related to this matter, it is possible that the ultimate liability resulting from this matter and the impact on the Company’s results of operations could be material.

Inherent uncertainties exist in the Company’s potential environmental liabilities primarily due to unknown conditions, whether future claims may fall outside the scope of the indemnity, changing governmental regulations and legal standards regarding liability, and evolving technologies for handling site remediation and restoration. In connection with the Company’s existing indemnification, the possibility is considered remote that environmental remediation costs will have a material adverse impact on the condensed consolidated financial statements over the next 12 months.

Purchase Commitments

In the normal course of business, the Company has certain raw material purchase contracts where it is required to purchase certain minimum volumes at current market prices. These commitments range from one to four years. In certain raw material purchase contracts, the Company has the right to purchase less than the required minimums and pay a liquidated damages fee, or, in case of a permanent plant shutdown, to terminate the contracts. In such cases, these obligations would be less than the annual commitment as disclosed in the Notes to Consolidated Financial Statements included in the Annual Report.

Asset Retirement Obligations

The Company has built certain manufacturing facilities on leased land and is required to remove these facilities at the end of the corresponding contract term. Legal obligations for these demolition and decommissioning activities exist in connection with the retirement of these assets triggered upon closure of the facilities. In instances when the Company plans to continue operations at these facilities indefinitely, and therefore, a reasonable estimate of fair value cannot be determined, an asset retirement obligation is not recognized.

In connection with the Asset Restructuring Plan as described within Note 17, the Company concluded the Boehlen, Germany site no longer had an indeterminate life. Accordingly, during the fourth quarter of 2022, the Company recorded the fair value of an asset retirement obligation and a corresponding asset retirement cost, which was capitalized as part of the carrying amount of the related long-lived assets and depreciated over the asset’s shortened useful life. The asset retirement cost was fully depreciated during the fourth quarter of 2022.

Obligations incurred		0.9

Accretion expense		0.5

Balance at end of period	$	35.6

Accretion expense is included within “Selling, general and administrative expenses” in the condensed consolidated statement of operations. The current portion of the asset retirement obligation is recorded within “Accrued expenses and other current liabilities” and the long-term portion is recorded within “Other noncurrent obligations” in the condensed consolidated balance sheets. As of March 31, 2023 and December 31, 2022, the current portion was $24.6 million and $25.3 million, respectively, and the long-term portion was $11.0 million and $10.5 million, respectively.

Litigation Matters

From time to time, the Company may be subject to various legal claims and proceedings incidental to the normal conduct of business, relating to such matters as employees, product liability, antitrust/competition, past waste disposal practices and release of chemicals into the environment. While it is impossible at this time to determine with certainty the ultimate outcome of these routine claims, the Company does not believe that the ultimate resolution of these claims

will have a material adverse effect on the Company’s results of operations, financial condition or cash flow. Legal costs, including those legal costs expected to be incurred in connection with a loss contingency, are expensed as incurred.

Legal Proceedings related to the Bristol Spill

(a) Jonnie Helfrich v. Trinseo PLC (No. 2:23-cv-01525) (United States District Court for the Eastern District of Pennsylvania)

On April 20, 2023, a complaint was filed which purports to be on behalf of a class of purchasers of the Company’s securities between May 3, 2021 and March 27, 2023. It names as defendants the Company and our chief executive officer and chief financial officer, and seeks unspecified damages and other relief for alleged violations of Sections 10(b) and 20(a) of, and Rule 10b-5 under, of the Securities Exchange Act of 1934. Given the early stage of this matter, we are not able to estimate whether a material loss to our business is probable or remote, or estimate a potential range of loss, if any. The Company intends to vigorously defend this action.

(b) Timothy McGraw, Emily Cohen & Danielle Byrd v. Altuglas LLC and Trinseo LLC (Court of Common Pleas of Philadelphia County)

On March 29, 2023, a putative class action complaint was filed which seeks to certify a class that could potentially include all persons and entities that reside in the area served by the Baxter Drinking Water Treatment Plant. The plaintiffs allege claims of breach of duty of care based on negligence as a result of the Bristol Spill, as well as other causes of action, and seek compensatory damages, restitution, or refund of damages, including actual, statutory, and punitive damages, as well as injunctive relief. Given the early stage of this matter, we are not able to estimate whether a material loss to our business is probable or remote, or estimate a potential range of loss, if any. The Company intends to vigorously defend this action.

(c) Environmental Proceedings

On March 25, 2023, the Company received a Notice of Federal Interest from the United States Coast Guard (“USCG”), identifying the Company as a “potentially responsible party” (“PRP”) related to the Bristol Spill. The Company also received a Notice of Federal Assumption and an Administrative Order, dated April 20, 2023 from the USCG, identifying the Company as a PRP related to the Bristol Spill. The USCG notices and order do not designate specific fines or penalties against the Company. It is not possible at this time for the Company to estimate its ultimate liability pursuant to the USCG notices or order, or other potential administrative actions related to the Bristol Spill, whether a material loss to our business is probable or remote, or estimate a potential range of loss, if any.

Synthos Matter

On November 21, 2022, the Company received formal notice from the German Arbitration Institute that Synthos had initiated an arbitration dispute on October 14, 2022 against Trinseo and its following subsidiaries: Trinseo Deutschland GmbH, Trinseo Belgium BV, Trinseo Europe GmbH, and Trinseo Export GmbH, related to Synthos’ purchase of Trinseo’s Rubber Business in 2021.

As discussed in Note 4, Synthos and Trinseo are parties to an asset purchase agreement (“APA”) dated May 21, 2021, whereby Trinseo transferred its Rubber Business to Synthos, pending regulatory approval and other administrative pre-closing conditions, for an enterprise value of approximately $491.0 million. This transaction formally closed on December 1, 2021. Synthos claims that Trinseo did not properly disclose certain information including the natural gas pricing mechanism for the steam which is supplied by a third party to the Rubber Business. Synthos is seeking non-monetary restitution and monetary damages related to the spike of utility prices in Germany that commenced in the fall of 2021.

The Company believes it has valid and prevailing defenses to Synthos’ claims and intends to vigorously defend itself against all allegations.

European Commission Request for Information

On June 6, 2018, Trinseo Europe GmbH, a subsidiary of the Company, received a request for information in the form of a letter from the European Commission Directorate General for Competition (the “European Commission”) related to styrene monomer commercial activity in the European Economic Area. The Company

subsequently commenced an internal investigation into these commercial activities and discovered instances of inappropriate activity.

As a result of further developments in this matter, during the first quarter of 2022, the Company recorded a charge of $35.6 million which is included within “Impairment and other charges” on the condensed consolidated statements of operations. In November 2022, the Company reached a final settlement with the European Commission in respect of this matter of $33.8 million, adjusted for foreign exchange rate impacts, which was subsequently paid in full in December 2022.

Service cost related to the Company’s defined benefit pension plans and other postretirement plans is included within “Cost of sales” and “Selling, general and administrative expenses,” whereas all other components of net periodic benefit cost are included within “Other expense (income), net” in the condensed consolidated statements of operations. As of March 31, 2023 and December 31, 2022, the Company’s benefit obligations included primarily in “Other noncurrent obligations” in the condensed consolidated balance sheets were $183.4 million and $177.8 million, respectively.

The Company made cash contributions and benefit payments to unfunded plans of approximately $1.7 million during the three months ended March 31, 2023. The Company expects to make additional cash contributions, including benefit payments to unfunded plans, of approximately $11.4 million to its defined benefit plans for the remainder of 2023.

RSUs		394,292	$	24.10
Options		438,727		10.86
PSUs		219,238		20.23

Option Awards

The following are the weighted average assumptions used within the Black-Scholes pricing model for the Company’s option awards granted during the three months ended March 31, 2023:

	Three Months Ended
	March 31, 2023
Expected term (in years)	5.50
Expected volatility	54.01	%
Risk-free interest rate	4.06	%
Dividend yield	2.00	%

The expected volatility assumption is determined based on the historical volatility of the Company’s publicly traded ordinary shares. The expected term of option awards represents the period of time that option awards granted are expected to be outstanding. For the option awards granted during the three months ended March 31, 2023, the simplified method was used to calculate the expected term, given the Company’s limited historical exercise data. The risk-free interest rate for the periods within the expected term of option awards is based on the U.S. Treasury yield curve in effect at the time of grant. The dividend yield is estimated based on historical and expected dividend activity.

Performance Share Units (PSUs)

The following are the weighted average assumptions used within the Monte Carlo valuation model for PSUs granted during the three months ended March 31, 2023:

		Three Months Ended
		March 31, 2023
Expected term (in years)		3.00
Expected volatility		62.60	%
Risk-free interest rate		4.41	%
Share price	$	24.08

Determining the fair value of PSUs requires considerable judgment, including estimating the expected volatility of the price of the Company’s ordinary shares, the correlation between the Company’s share price and that of its peer companies, and the expected rate of interest. The expected volatility for each grant is determined based on the historical volatility of the Company’s ordinary shares. The expected term of PSUs represents the length of the performance period.

The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for a duration equivalent to the performance period. The share price is the closing price of the Company’s ordinary shares on the grant date.

Segments

NOTE 16—SEGMENTS

The Company operates under six segments: Engineered Materials, Latex Binders, Plastics Solutions, Polystyrene, Feedstocks, and Americas Styrenics. On January 1, 2023, the Base Plastics segment was renamed to Plastics Solutions to better reflect Trinseo’s strategic focus on providing solutions in areas such as sustainability and material substitution. The Engineered Materials segment includes the Company’s compounds and blends products sold into higher growth and value applications, such as consumer electronics and medical, as well as soft thermoplastic elastomers (“TPEs”) products which are sold into markets such as footwear and automotive. Additionally, following the PMMA Acquisition and the Aristech Surfaces Acquisition in 2021, the Engineered Materials segment also includes PMMA and MMA products, which are sold into a variety of applications including automotive, building & construction, medical, consumer electronics, and wellness, among others. The Latex Binders segment produces styrene-butadiene latex (“SB latex”) and other latex polymers and binders, primarily for coated paper and packaging board, carpet and artificial turf backings, as well as a number of performance latex binders applications, such as adhesive, building and construction and the technical textile paper market. The Plastics Solutions segment contains the results of the acrylonitrile-butadiene-styrene (“ABS”), styrene-acrylonitrile (“SAN”), and polycarbonate (“PC”) businesses, as well as compounds and blends for automotive and other applications. The Plastics Solutions segment also includes the results of Heathland, which was acquired in the first quarter of 2022. The Polystyrene segment includes a variety of general purpose polystyrenes (“GPPS”) and polystyrene that has been modified with polybutadiene rubber to increase its impact resistant properties (“HIPS”). The Feedstocks segment includes the Company’s production and procurement of styrene monomer outside of North America, which is used as a key raw material in many of the Company’s products, including polystyrene, SB latex, and ABS resins. Lastly, the Americas Styrenics segment consists solely of the operations of the Company’s 50%-owned joint venture, Americas Styrenics, a producer of both styrene monomer and polystyrene in North America.

The following table provides disclosure of the Company’s segment Adjusted EBITDA, which is used to measure segment operating performance and is defined below, for the three months ended March 31, 2023 and 2022. Asset and intersegment sales information by reporting segment is not regularly reviewed or included with the Company’s reporting to the chief operating decision maker. Therefore, this information has not been disclosed below. Refer to Note 5 for the Company’s net sales to external customers by segment for the three months ended March 31, 2023 and 2022.

(1) The Company’s primary measure of segment operating performance is Adjusted EBITDA, which is defined as income from continuing operations before interest expense, net; provision for income taxes; depreciation and amortization expense; loss on extinguishment of long-term debt; asset impairment charges; gains or losses on the dispositions of businesses and assets; restructuring charges; acquisition related costs and benefits and other items. Segment Adjusted EBITDA is a key metric that is used by management to evaluate business performance in comparison to budgets, forecasts, and prior year financial results, providing a measure that management believes reflects core operating performance by removing the impact of transactions and events that would not be considered a part of core operations. Other companies in the industry may define segment Adjusted EBITDA differently than the Company, and as a result, it may be difficult to use segment Adjusted EBITDA, or similarly named financial measures, that other companies may use to compare the performance of those companies to the Company’s segment performance.

The reconciliation of income from continuing operations before income taxes to segment Adjusted EBITDA is as follows:

(1) In December 2022, the Company announced an asset restructuring plan designed to reduce costs, improve profitability, reduce exposure to cyclical markets and elevated natural gas prices, and address market overcapacity. The asset restructuring plan includes (i) closure of manufacturing operations at the styrene production facility in Boehlen, Germany, (ii) closure of one of its production lines at the Stade, Germany polycarbonate plant, and (iii) closure of the PMMA sheet manufacturing site in Matamoros, Mexico. The program is expected to be substantially completed by the end of 2024. In connection with this restructuring plan, during the three months ended March 31, 2023, the Company incurred employee termination benefit charges of $(0.6) million, contract termination charges of $2.5 million, accelerated depreciation charges of $4.0 million, and decommissioning and other charges of $1.8 million. Production at all facilities have ceased and decommissioning activities are expected to continue through the end of 2024. The Company expects to incur incremental contract termination charges of $17.6 million, decommissioning and other charges of $2.2 million, as well as a limited amount of incremental employee termination benefit charges, the majority of which is expected to be paid by the end of 2024. Of the total incremental charges, $18.6 million is expected to be incurred in the Feedstocks segment, and $1.2 million is expected to be incurred in the Plastics Solution segment.

On April 4, 2023, the Company entered into an agreement to sell its land, buildings and equipment in Matamoros, Mexico for a cash consideration of approximately $19.0 million. The transaction is expected to close within the second quarter of 2023.

(2) In May 2021, the Company approved a transformational restructuring program associated with the Company’s strategic initiatives. The Company expects to incur incremental employee termination benefit charges related to impacted employees as of March 31, 2023 of less than $1.0 million, the majority of which are expected to be paid in 2023. As this was identified as a corporate-related activity, the charges related to this restructuring program were not allocated to a specific segment, but rather included within corporate unallocated.

Refer to Note 13 for further information regarding the asset retirement obligation. The following table provides a roll forward of the other liability balances associated with the Company’s restructuring activities as of March 31, 2023. Employee termination benefit and contract termination charges are primarily recorded within “Accrued expenses and other current liabilities” in the condensed consolidated balance sheets.

Earnings Per Share

Earnings Per Share

NOTE 19—EARNINGS PER SHARE

Basic earnings per ordinary share (“basic EPS”) is computed by dividing net income available to ordinary shareholders by the weighted average number of the Company’s ordinary shares outstanding for the applicable period. Diluted earnings per ordinary share (“diluted EPS”) is calculated using net income available to ordinary shareholders divided by diluted weighted average ordinary shares outstanding during each period, which includes unvested RSUs, option awards, and PSUs. Diluted EPS considers the impact of potentially dilutive securities except in periods in which there is a loss from continuing operations because the inclusion of the potential ordinary shares would have an anti-dilutive effect.

The following table presents basic EPS and diluted EPS for the three months ended March 31, 2023 and 2022.

(1) Refer to Note 15 for discussion of RSUs, option awards, and PSUs granted to certain Company directors and employees. As the Company recorded a net loss from continuing operations for the three months ended

March 31, 2023, potential shares related to equity-based awards have been excluded from the calculation of diluted EPS, as doing so would be anti-dilutive. There were 0.9 million anti-dilutive shares that have been excluded from the computation of diluted earnings per share for the three months ended March 31, 2022.

Recent Accounting Guidance

Basis of Presentation

The unaudited interim condensed consolidated financial statements of Trinseo PLC and its subsidiaries (the “Company”) as of and for the periods ended March 31, 2023 and 2022 were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and reflect all adjustments, consisting only of normal recurring adjustments, which, in the opinion of management, are considered necessary for the fair statement of the results for the periods presented. Because they cover interim periods, the statements and related notes to the financial statements do not include all disclosures normally provided in annual financial statements, and therefore, these statements should be read in conjunction with the 2022 audited consolidated financial statements included within the Company’s Annual Report on Form 10-K (“Annual Report”) filed with the Securities and Exchange Commission (“SEC”) on February 27, 2023. The Company’s condensed consolidated financial statements presented herein reflect the latest estimates and assumptions made by management that affect the reported amounts and related disclosures as of and for the period ended March 31, 2023. However, actual results could differ from these estimates and assumptions.

The December 31, 2022 condensed consolidated balance sheet data presented herein was derived from the Company’s December 31, 2022 audited consolidated financial statements, but does not include all disclosures required by GAAP for annual periods.

Throughout this Quarterly Report, unless otherwise indicated, amounts and activity are presented on a continuing operations basis.

(1) This caption does not include deferred financing fees related to the Company’s revolving facilities, which are included within “Deferred charges and other assets” on the condensed consolidated balance sheets.

(2) As of March 31, 2023, under the 2026 Revolving Facility, the Company had a capacity of $375.0 million and $22.0 million outstanding letters of credit. As of March 31, 2023, the Company had funds available for borrowing of $100.5 million (net of the applicable $12.0 million outstanding letters of credit as defined in the secured credit agreement), which reflects the borrowing limit imposed by the springing covenant. The springing covenant applies when 30% or more of the 2026 Revolving Facility’s capacity is drawn which then requires the Company to meet a first lien net leverage ratio (as defined in the secured credit agreement) not to exceed 3.50x at the end of each financial quarter. As of March 31, 2023, the first lien net leverage ratio was 4.85x and the outstanding borrowings did not exceed the 30% threshold. Additionally, the Company is required to pay a quarterly commitment fee in respect of any unused commitments under this facility equal to 0.375% per annum.

(3) As of March 31, 2023, this facility had a borrowing capacity of $150.0 million, and the Company had approximately $150.0 million of accounts receivable available to support this facility, based on the pool of eligible accounts receivable.

(4) The current portion of long-term debt was primarily related to $14.5 million of the scheduled future principal payments on both the 2024 Term Loan B and 2028 Term Loan B as of March 31, 2023 and December 31, 2022.

(1) The Company’s primary measure of segment operating performance is Adjusted EBITDA, which is defined as income from continuing operations before interest expense, net; provision for income taxes; depreciation and amortization expense; loss on extinguishment of long-term debt; asset impairment charges; gains or losses on the dispositions of businesses and assets; restructuring charges; acquisition related costs and benefits and other items. Segment Adjusted EBITDA is a key metric that is used by management to evaluate business performance in comparison to budgets, forecasts, and prior year financial results, providing a measure that management believes reflects core operating performance by removing the impact of transactions and events that would not be considered a part of core operations. Other companies in the industry may define segment Adjusted EBITDA differently than the Company, and as a result, it may be difficult to use segment Adjusted EBITDA, or similarly named financial measures, that other companies may use to compare the performance of those companies to the Company’s segment performance.

(1) In December 2022, the Company announced an asset restructuring plan designed to reduce costs, improve profitability, reduce exposure to cyclical markets and elevated natural gas prices, and address market overcapacity. The asset restructuring plan includes (i) closure of manufacturing operations at the styrene production facility in Boehlen, Germany, (ii) closure of one of its production lines at the Stade, Germany polycarbonate plant, and (iii) closure of the PMMA sheet manufacturing site in Matamoros, Mexico. The program is expected to be substantially completed by the end of 2024. In connection with this restructuring plan, during the three months ended March 31, 2023, the Company incurred employee termination benefit charges of $(0.6) million, contract termination charges of $2.5 million, accelerated depreciation charges of $4.0 million, and decommissioning and other charges of $1.8 million. Production at all facilities have ceased and decommissioning activities are expected to continue through the end of 2024. The Company expects to incur incremental contract termination charges of $17.6 million, decommissioning and other charges of $2.2 million, as well as a limited amount of incremental employee termination benefit charges, the majority of which is expected to be paid by the end of 2024. Of the total incremental charges, $18.6 million is expected to be incurred in the Feedstocks segment, and $1.2 million is expected to be incurred in the Plastics Solution segment.

On April 4, 2023, the Company entered into an agreement to sell its land, buildings and equipment in Matamoros, Mexico for a cash consideration of approximately $19.0 million. The transaction is expected to close within the second quarter of 2023.

(2) In May 2021, the Company approved a transformational restructuring program associated with the Company’s strategic initiatives. The Company expects to incur incremental employee termination benefit charges related to impacted employees as of March 31, 2023 of less than $1.0 million, the majority of which are expected to be paid in 2023. As this was identified as a corporate-related activity, the charges related to this restructuring program were not allocated to a specific segment, but rather included within corporate unallocated.
