Trinseo PLC

Quarterly Report on Form 10-Q

For the quarterly period ended ~~September 30, 2021~~March 31, 2022

On October 8, 2021, Trinseo PLC completed a previously-announced merger pursuant to which our former publicly-traded parent entity, Trinseo S.A., a Luxembourg limited liability company, was merged with and into Trinseo PLC, an Irish public limited company, with Trinseo PLC as the surviving entity (the “Redomiciliation”). The Redomiciliation was completed pursuant to an agreement between the parties entitled the Common Draft Terms of Merger dated as of April 23, 2021 and was approved by shareholders at Trinseo S.A.’s 2021 annual general meeting on June 10, 2021. As a result of the Redomiciliation, all of Trinseo S.A.’s outstanding ordinary shares, par value $0.01 per share, excluding treasury shares, were exchanged on a one-for-one basis for newly issued ordinary shares, par value $0.01 per share, of Trinseo PLC.

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 approved by shareholders in June 2021 and completed in October 2021. All financial data provided in this Quarterly Report is the financial data of ~~the Company,~~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, ~~2020~~2021 (“Annual Report”) filed with the Securities and Exchange Commission (“SEC”) on February ~~22, 2021.~~23, 2022.The Company may distribute cash to shareholders under Irish law via repayments of equity or an allocation of statutory profits. All distributions prior to 2020 were considered repayments of equity under Luxembourg law, wherein the Company was previously domiciled.

Cautionary Note on Forward-Looking Statements

This Quarterly Report contains, ~~forward-looking statements including,~~ 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,” “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 ~~the timing of the proposed sale of our Synthetic Rubber business and expected proceeds of the proposed sale,~~ 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 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 complete the sale of our ~~Synthetic Rubber~~Styrenics business; our ability to successfully execute our transformation strategy and business strategy; our ability to integrate acquired businesses; global supply chain volatility, increased costs or disruption in the supply of raw materials or increased costs for transportation of our products; the European Commission request for information; the nature of investment opportunities presented to the Company from time to time; and those discussed in our Annual Report filed with the SEC on February ~~22, 2021~~23, 2022 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 ~~September 30,~~March 31, 2022 and 2021 ~~and 2020~~ 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 ~~2020~~2021 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 ~~22, 2021.~~23, 2022. 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 ~~September 30, 2021.~~March 31, 2022. However, actual results could differ from these estimates and assumptions.

On October 8, 2021, the Company completed a cross-border merger transaction, pursuant to which its former publicly-traded parent entity, Trinseo S.A., a Luxembourg limited liability company, was merged with and into Trinseo PLC, an Irish public limited company, with Trinseo PLC as the surviving entity (the “Redomiciliation”). The Redomiciliation was completed pursuant to an agreement between the parties entitled the Common Draft Terms of Merger dated as of April 23, 2021 and was approved by shareholders at Trinseo S.A.’s 2021 annual general meeting on June 14, 2021. As a result of the Redomiciliation, all of Trinseo S.A.’s outstanding ordinary shares, par value $0.01 per share, excluding treasury shares, were exchanged on a one-for-one basis for newly issued ordinary shares, par value $0.01 per share, of Trinseo PLC. The treasury shares of Trinseo S.A. were cancelled in conjunction with the Redomiciliation. All references herein to “Trinseo” or the “Company” refer to Trinseo S.A. and its subsidiaries through the effective date of the Redomiciliation, and thereafter refer to Trinseo PLC and its subsidiaries. As the Redomiciliation was completed subsequent to September 30, 2021, amounts presented herein represent the results of Trinseo S.A. as of and for the periods ended September 30, 2021 and have not been adjusted for the equity transactions completed in connection with the Redomiciliation on October 8, 2021.

The December 31, ~~2020~~2021 condensed consolidated balance sheet data presented herein was derived from the Company’s December 31, ~~2020~~2021 audited consolidated financial statements, but does not include all disclosures required by GAAP for annual periods.

Certain prior year amounts have been reclassified to conform to the current year presentation. These reclassifications pertain primarily to the Company’s entry into an agreement during the second quarter of 2021 to sell its Synthetic Rubber business, as a result of which the Company reclassified its Synthetic Rubber assets and liabilities as held-for-sale and reclassified the operating results of its Synthetic Rubber business, net of taxes, as discontinued operations for all periods presented. The sale of the Synthetic Rubber business was completed in December 2021. Refer to Note 4 for further information. Throughout this Quarterly Report, unless otherwise indicated, amounts and activity are presented on a continuing operations basis. ~~Additionally, the condensed consolidated financial statements herein reflect reclassifications related to the Company’s resegmentation effective October 1, 2020, as described in Note 16.~~

NOTE 2—RECENT ACCOUNTING GUIDANCE

~~In December 2019, the FASB~~As of March 31, 2022, there was no recently issued ~~guidance that simplifies the~~ accounting for income taxes. The amended guidance includes removal of certain exceptions to the general principles of Accounting Standards Codification (“ASC”) 740, Income Taxes, and simplification in several other areas such as accounting for a franchise tax (or similar tax) that is partially based on income. ~~The Company adopted the guidance effective January 1, 2021, noting that adoption did not~~standards which would have a material ~~impact~~effect on ~~its~~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”). The Heathland Acquisition was completed pursuant to the Sale and Purchase Agreement dated December 3, 2021 (“Heathland Agreement”), by and between the Company and Heathland Holding.

In accordance with ASC 805, fair values are assigned to tangible and identifiable intangible assets acquired and liabilities assumed at the acquisition date based on the information that was available as of the acquisition date. The Company believes that the information available provides a reasonable basis for estimating the fair values of assets acquired and liabilities assumed for the acquisition, however, preliminary measurements of fair value, ~~including, but not limited~~are subject to ~~inventory, intangible assets, property, plant and equipment, contingent liabilities, and such changes could be material. During~~change during the measurement period, if new information is obtained about facts and circumstances that existed as of the acquisition date that, if known, would have resulted in revised estimated values of those assets or liabilities as of that date we will revise the preliminary purchase price allocation. The effect of measurement period adjustments to the estimated fair values will be reflected as if the adjustments had been completed on the acquisition date. The impact of all changes that do not qualify as measurement period adjustments will be included in current period earnings.period.

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. The excess of the purchase price over the aggregate fair values was recorded as goodwill. The Company calculated the fair value of the assets acquired using the income and cost approaches (or a combination thereof). Fair values were determined based on various inputs including estimated future cash flows, discount rates, royalty rates, growth rates, sales projections, retention rates and terminal values, all of which require significant management judgment.

~~(1)~~

The PMMA Acquisition had an initial purchase price consideration of $1,370.7 million, of which $1,369.0 million was paid during the second quarter of 2021. This initial purchase price consideration remains subject to customary working capital and other closing adjustments.

~~(2)~~

Known purchase price adjustment not yet paid relates primarily to consideration for estimated working capital adjustments and certain assets at the Porto Marghera, Italy manufacturing site which will be legally transferred to Trinseo at a later date due to local transfer restrictions; however, the Company has the benefits and risks of ownership during the period from May 3, 2021 until the site legally transfers. This purchase price consideration is expected to be paid in the fourth quarter of 2021.

The PMMA Acquisition was funded using the net proceeds from the Company’s new financing arrangements, including $450.0 million from its 2029 Senior Notes issued on March 24, 2021 and $750.0 million of incremental borrowings under the 2028 Term Loan B entered into in conjunction with closing of the transaction, as well as available cash. Refer to Note 8 for further information on the financing arrangements used to fund the PMMA Acquisition.

The Company accounted for the PMMA Acquisition as a business combination pursuant to ASC 805. In accordance with ASC 805, fair values are assigned to tangible and identifiable intangible assets acquired and liabilities assumed at the acquisition date based on the information that was available as of that date. The Company believes that the information available provides a reasonable basis for estimating the fair values of assets acquired and liabilities assumed for the PMMA Acquisition; however, preliminary measurements of fair value, including, but not limited to, inventory, intangible assets, property, plant and equipment, pension and postretirement obligations, contingent liabilities, including environmental remediation obligations, and deferred tax assets and liabilities are subject to change during the measurement period, and such changes could be material. The Company expects to finalize the valuation and accounting for the PMMA Acquisition as soon as practicable, but no later than one year after the acquisition date. During the measurement period, if new information is obtained about facts and circumstances that existed as of the acquisition date that, if known, would have resulted in revised estimated values of those assets or liabilities as of that date, the Company will revise the preliminary purchase price allocation. The effect of measurement period adjustments to the estimated fair values will be reflected as if the adjustments had been completed on the acquisition date.

~~The PMMA business acquisition contributed net sales and net loss of $332.1 million and $5.4 million, respectively, to the Company’s results for the period from May 3, 2021 to September 30, 2021.~~

~~Transaction-related costs~~

Pursuant to GAAP, costs incurred to complete the PMMA Acquisition as well as costs incurred to integrate into our operations are expensed as incurred. The Company incurred $0.2 million and $20.0 million of transaction-related costs for the three and nine months ended September 30, 2021, respectively. The amounts were recorded within “Selling, general and administrative expenses” in the Company’s condensed consolidated statements of operations, and are reflected in the nine months ended September 30, 2020 in the supplemental pro forma information below.

In connection with the PMMA Acquisition, the Company entered into certain customary transitional services agreements with Arkema to provide for the orderly separation and transition of various functions and processes. These services will be provided by Arkema to the Company for up to 18 months after closing, with certain extension options available. These services include information technology, accounting and finance, procurement, supply chain, and other services, while we assume the operations of the PMMA business.

Additionally, the Company paid Arkema $10.6 million for certain information technology separation costs in order to support the transition services agreements entered into at the time of close. These payments have not been included as a component of consideration transferred, and instead have been capitalized as prepaid assets within “Other current assets” on the condensed consolidated balance sheets. The cost will be recognized as expense over the period in which the services are expected to be rendered under the transition services agreements.

Amounts for operating net sales and costs of sales which had previously been eliminated in consolidation related to intercompany sales of styrene monomer to the Synthetic Rubber business are now reflected on a gross basis as a component of net sales and costs of sales from continuing operations for all periods presented. The Company has recast these amounts because upon completion of the sale of the Synthetic Rubber business, the Company will continue to have these ongoing transactions with Synthos, under a supply agreement executed in conjunction with the divestiture. Refer to Note 5 for recast segment net sales reflecting this adjustment.

Additionally, the Company previously allocated certain corporate management overhead costs to the former Synthetic Rubber segment which may no longer be allocated to discontinued operations under the relevant authoritative accounting guidance. Accordingly, the Company has recast its segment reporting results to reflect the reattribution of these expenses in all periods presented. Refer to Note 16 for recast segment results reflecting this adjustment.

NOTE 5—NET SALES

Refer to the Annual Report for information on the Company's accounting policies and further background related to its net sales.

Interest on the 2029 Senior Notes is payable semi-annually on February 15 and August 15 of each year, commencing on August 15, 2021. The 2029 Senior Notes mature on April 1, 2029. The net proceeds from the 2029 Senior Notes offering were used as a portion of the funding needed for the PMMA Acquisition, in addition to fees and expenses related to the offering and the PMMA Acquisition. The gross proceeds from the 2029 Senior Notes offering were released upon satisfaction of certain escrow release conditions, including closing of the PMMA Acquisition, which was completed on May 3, 2021.

~~Table of Contents~~

At any time prior to April 1, 2024, the Issuers may redeem the 2029 Senior Notes in whole or in part, at their option, at a redemption price equal to 100% of the principal amount of such notes plus the relevant applicable premium as of, and accrued and unpaid interest to, but not including, the redemption date.

The 2029 Senior Notes are the Issuers’ senior unsecured obligations and rank equally in right of payment with all of the Issuers’ existing and future indebtedness that is not expressly subordinated in right of payment thereto. The 2029 Senior Notes will be senior in right of payment to any future indebtedness that is expressly subordinated in right of payment thereto and effectively junior to (a) the Issuers’ existing and future secured indebtedness, including the Company’s accounts receivable facility and the Issuers’ Credit Facility, to the extent of the value of the collateral securing such indebtedness and (b) all existing and future liabilities of the Issuers’ non-guarantor subsidiaries.

The Indenture contains customary covenants, including restrictions on the Issuers’ and certain of its subsidiaries’ ability to incur additional indebtedness and guarantee indebtedness; pay dividends on, redeem or repurchase capital stock; make investments; prepay certain indebtedness; create liens; enter into transactions with the Issuers’ affiliates; designate the Issuers’ subsidiaries as Unrestricted Subsidiaries (as defined in the Indenture); and consolidate, merge, or transfer all or substantially all of the Issuers’ assets. The covenants are subject to a number of exceptions and qualifications. Certain of these covenants, excluding without limitation those relating to transactions with the Issuers’ affiliates and consolidation, merger, or transfer of all or substantially all of the Issuers’ assets, will be suspended during any period of time that (1) the 2029 Senior Notes have Investment Grade Status (as defined in the Indenture) and (2) no default has occurred and is continuing under the Indenture. In the event that the 2029 Senior Notes are downgraded to below an Investment Grade Status, the Issuers and certain subsidiaries will again be subject to the suspended covenants with respect to future events. ~~As of September 30, 2021, the Company was in compliance with all debt covenant requirements under the Indenture.~~

Total fees incurred in connection with the issuance of the 2029 Senior Notes were $15.9 million, which were capitalized and recorded within “Long-term debt, net of unamortized deferred financing fees” on the condensed consolidated balance sheet, and are being amortized into “Interest expense, net” in the condensed consolidated statements of operations over their ~~eight-year~~ ~~term using the effective interest method.~~

~~Senior Credit Facility~~

On May 3, 2021, the Issuers entered into (i) an amendment to the existing credit agreement dated as of September 6, 2017 in which the Issuers borrowed a new tranche of term loans in an aggregate amount of $750.0 million senior secured term loan B facility maturing in May 2028 (the “2028 Term Loan B”), used to finance a portion of the purchase price of the PMMA Acquisition, and (ii) an amendment to the existing credit agreement, pursuant to which the existing revolving credit facility has been refinanced with a new revolving credit facility in an aggregate amount of $375.0 million, with a $25.0 million swingline subfacility and a $35.0 million letter of credit subfacility, maturing in May 2026. Amounts under the 2026 Revolving Facility are available in U.S. dollars and euros. The terms under the 2026 Revolving Facility are substantially unchanged from the 2022 Revolving Facility. Refer to the Annual Report for the terms of the 2022 Revolving Facility. As a result of amending the revolving credit facility, during the nine months ended September 30, 2021, the Company recognized a $0.5 million loss on extinguishment of long-term debt related to the write-off of a portion of the existing unamortized deferred financing fees. This amount has been recorded with “Other expense (income), net” in the condensed consolidated statement of operations.

~~Table of Contents~~

The 2028 Term Loan B bears an interest rate of LIBOR plus 2.50%, subject to a 0.00% LIBOR floor, and was issued at a 0.5% original issue discount. Further, the 2028 Term Loan B requires scheduled quarterly payments in amounts equal to 0.25% of the original principal amount of the 2028 Term Loan B, with the balance to be paid at maturity.

The 2026 Revolving Facility contains a financial covenant that requires compliance with a springing first lien net leverage ratio test. If the outstanding balance under the 2026 Revolving Facility exceeds 30% of the $375.0 million borrowing capacity (excluding undrawn letters of credit up to $10.0 million and cash collateralized letters of credit) at a quarter end, then the Borrowers’ first lien net leverage ratio may not exceed 3.50 to 1.00. As of September 30, 2021, the Company was in compliance with all debt covenant requirements under the Senior Credit Facility.

Fees incurred in connection with the issuance of the 2028 Term Loan B were $18.7 million, which were capitalized and recorded within “Long-term debt, net of unamortized deferred financing fees” on the condensed consolidated balance sheet, and are being amortized into “Interest expense, net” in the condensed consolidated statements of operations over their ~~seven-year~~ ~~term using the effective interest method.~~

Fees incurred in connection with the 2026 Revolving Facility were $0.4 million, which were capitalized and recorded within “Deferred charges and other assets” on the condensed consolidated balance sheet, and are being amortized along with the remaining $0.8 million of unamortized deferred financing fees from the Company’s former revolving credit facility (“2022 Revolving Facility”) into “Interest expense, net” in the condensed consolidated statements of operations over the ~~five-year~~ ~~term of the facility using the straight-line method.~~

NOTE 10—DERIVATIVE INSTRUMENTS

The Company’s ongoing business operations expose it to various risks, including fluctuating foreign exchange rates and interest rate risk. To manage these risks, the Company periodically enters into derivative financial instruments, such as foreign exchange forward contracts and interest rate swap agreements. 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. The Company entered into a specific such foreign exchange forward contract in December 2020 in order to economically hedge the euro-denominated purchase

~~Table of Contents~~

price of the Arkema PMMA business, which was acquired on May 3, 2021, as discussed in Note 3. These derivative contracts are not designated for hedge accounting treatment.

As of ~~September 30, 2021,~~March 31, 2022, the Company had open foreign exchange forward contracts with a notional U.S. dollar equivalent absolute value of ~~$1,177.9~~$763.6 million. The following table displays the notional amounts of the most significant net foreign exchange hedge positions outstanding as of ~~September 30, 2021:~~March 31, 2022:

Korean Won	$	(15.3)

Open foreign exchange forward contracts as of ~~September 30, 2021~~March 31, 2022 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 1 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.

~~Open~~The Company had 0 open foreign exchange cash flow hedges as of ~~September 30, 2021 had maturities occurring over a period of three months, and had a net notional U.S. dollar equivalent of $24.0 million.~~ March 31, 2022.

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

Table of Contents

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.

As of ~~September 30, 2021,~~March 31, 2022, the Company had open interest rate swap agreements with a net notional U.S. dollar equivalent of $200.0 million which had an effective date of September 29, 2017 and mature in September 2022. Under the terms of the swap agreements, the Company is 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 ~~(0.08%~~(0.21% as of ~~September 30, 2021)~~March 31, 2022) from the counterparties.

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. ~~The~~When applicable, the Company amortizes any initial excluded component value of a CCS as

~~Table of Contents~~

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. The 2017 CCS was initially designated under the forward method and then redesignated under the spot method effective April 1, 2018. At the time of redesignation, the 2017 CCS had a cumulative foreign currency translation loss in AOCI of $38.0 million. The excluded component value related to the 2017 CCS at April 1, 2018 was $23.6 million, which was being amortized over its remaining term. 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. Upon settlement of the 2017 CCS, the Company realized net cash proceeds of $51.6 million. The remaining $13.8 million unamortized balance of the initial excluded component related to the 2017 CCS at the time of settlement will remain in AOCI until either the sale or substantially complete liquidation of the relevant subsidiaries. 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.

Subsequent to the end of the first quarter, 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.

Balance as of December 31, 2020 includes a $7.3 million receivable representing the fair value of the forward currency hedge arrangement on the euro-denominated purchase price of the Arkema PMMA business.

Forward contracts, interest rate swaps, 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

~~Table of Contents~~

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 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, ~~2020,~~2021, which were still held as of ~~September 30, 2021.~~March 31, 2022. These financial assets represent the Company’s styrene monomer assets in Boehlen, Germany, which it continues to operate. 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. ~~As a result of the fair value measurements performed, the Company recorded impairment charges on the Boehlen styrene monomer assets of $10.3 million during the first quarter of 2020.~~ During the three ~~and nine~~ months ended ~~September 30, 2021,~~March 31, 2022, the Company recorded additional impairment charges of ~~$0.3 million and $2.1~~$0.7 million related to capital expenditures at the Boehlen styrene monomer facility that it determined to be impaired, which are also included within ~~“Impairment~~“Other charges” on the condensed consolidated statements of operations. Refer to the Company’s Annual Report for further information. As of ~~September 30, 2021~~March 31, 2022 and December 31, ~~2020,~~2021, the value of the Boehlen styrene monomer assets are recorded at ~~$3.5~~$3.3 million and ~~$3.7~~$3.4 million, respectively, within the Company’s condensed consolidated balance sheets herein.

The Company’s polybutadiene rubber (“PBR,” specifically nickel and neodymium PBR) assets in Schkopau, Germany, which were mothballed in 2020, had also been measured on a nonrecurring basis during the year ended December 31, 2020, resulting in impairment charges of $28.0 million being recorded during the first quarter of 2020. However, as the Schkopau PBR assets are part of the Synthetic Rubber business, during the second quarter of 2021 they were classified as held-for-sale and their operating results were classified as discontinued operations for all periods presented, along with the rest of the Synthetic Rubber business. Refer to Note 4 for further information.

There were no0 other financial assets or liabilities measured at fair value on a nonrecurring basis as of December 31, ~~2020.~~2021.

~~Table of Contents~~

The effective income tax rate for the three months ended ~~September 30, 2021~~March 31, 2022 was ~~significantly~~primarily impacted by ~~the release~~an estimated liability of ~~a valuation allowance of $16.3~~$35.6 million ~~as a result of improvements in actual business operations and projected future results of one of the Company’s subsidiaries in China.~~

The effective income tax rate for the three and nine months ended September 30, 2020 was primarily driven by the Company’s overall forecasted jurisdictional mix of earnings, where the tax benefit on losses expected to be generated in lower rate jurisdictions was offset by tax expense on income expected to be generated in higher tax jurisdictions.~~Also impacting the rate for the nine months ended September 30, 2020 was a tax benefit~~ related to the ~~impairment charges recorded during the period related to the Company’s assets in Boehlen, Germany. Refer to~~European Commission request for information, as described within Note 1113 in the condensed consolidated financial statements, for ~~further~~which the Company estimates no tax benefit based on currently available information.

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, no0 environmental claims have been asserted or threatened against the ~~Company, and the~~Company. The Company is not a potentially responsible party for any material amounts at any Superfund Sites. As of ~~September 30,~~March 31, 2022 and December 31, 2021, the Company had ~~$5.1~~$4.2 million and $4.4 million, respectively, 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. ~~The Company had no accrued obligations for environmental remediation or restoration costs as of December 31, 2020.~~

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 ~~seven~~five 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.

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.

European Commission Request for Information

On June 6, 2018, Trinseo Europe GmbH, a subsidiary of the Company, received a ~~Request~~request for ~~Information~~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.

On October 28, 2019, a supplemental request for information was received from the European Commission. This

The Company has provided ~~this~~all information requested and continues to fully cooperate with the European Commission.

As a result of further developments in this matter, during the three months ended March 31, 2022, the Company recorded a reserve for an estimated liability of $35.6 million, which is included within “Other charges” on the condensed consolidated statements of operations.

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 ~~nine~~three months ended ~~September 30, 2021:~~March 31, 2022:


	~~Nine~~Three Months Ended
	~~September 30, 2021~~March 31, 2022
Expected term (in years)	5.50
Expected volatility	~~48.69~~48.84	%
Risk-free interest rate	~~0.78~~1.94	%
Dividend yield	~~1.81~~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 ~~nine~~three months ended ~~September 30, 2021,~~March 31, 2022, 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 ~~nine~~three months ended ~~September 30, 2021:~~March 31, 2022:


		Nine Months Ended			Three Months Ended
		September 30, 2021			March 31, 2022

Expected volatility		58.00	%		57.30	%
Risk-free interest rate		0.20	%		1.73	%
Share price	$	61.06		$	58.64

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.

NOTE 16—SEGMENTS

~~Beginning~~As discussed in the Annual Report, beginning in the second quarter of 2021, the Company reported the results of the Synthetic Rubber business as discontinued operations in the condensed consolidated statements of operations for all periods presented, and therefore it is no longer presented as a separate reportable segment. Refer to Note 4 for further information. Additionally, as discussed in the Annual Report, the Company realigned its reporting segments effective October 1, 2020, as a result of which the Company’s former Performance Plastics segment was reorganized into 2 standalone reporting segments: Engineered Materials and Base Plastics. There were no changes to the Company’s remaining 4 segments. Refer to the Annual Report for further information on the resegmentation. The information in the tables below has been retroactively adjusted to reflect these changes in reporting segments.

Table of Contents

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 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 on May 3, 2021 and the Aristech Surfaces Acquisition on September 1, 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 Base Plastics 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 Base Plastics 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 ~~and nine~~ months ended ~~September 30, 2021~~March 31, 2022 and ~~2020.~~2021. 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.

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.

These AOCI components are included in the computation of net periodic benefit costs (see Note 14).

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.

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. Other highlights for the year are described below.

~~Redomiciliation to Ireland~~European Commission Request for Information

On October 8, 2021, we completed the previously-announced cross-border merger transaction, pursuant to which our former publicly-traded parent company, Trinseo S.A., a Luxembourg limited liability company, was merged with and into Trinseo PLC, an Irish public limited company, as successor issuer to Trinseo S.A. (the “Redomiciliation”). The Redomiciliation was approved by the High Court of Ireland and by Trinseo shareholders at the Company’s annual general meeting. The Redomiciliation is expected to provide Trinseo with a favorable legal and regulatory infrastructure, simplify regulatory requirements, provide dividend withholding tax benefits to shareholders and provide operational efficiencies and reductions in its operating and administrative costs. All references herein to “Trinseo” or the “Company” refer to Trinseo S.A. and its subsidiaries through the effective date of the Redomiciliation, and thereafter refer to Trinseo PLC and its subsidiaries.

In 2018, Trinseo received a request for information from the ~~Redomiciliation, each~~European Commission Directorate General for Competition (the “European Commission”) related to styrene monomer commercial activity in the European Economic Area, as well as subsequent requests for information. Trinseo ~~shareholder received an ordinary share of Trinseo PLC for every ordinary share of Trinseo S.A. that they then held,~~has fully responded to all information requests from the European Commission and continues to fully cooperate on ~~a one-for-one basis.~~this matter, which remains ongoing. As a result of further developments in this matter, during the ~~Redomiciliation,~~three months ended March 31, 2022, Trinseo recorded a reserve for an estimated liability of $35.6 million. Refer to Note 13 in the ordinary shares of Trinseo S.A. were suspended from trading on the New York Stock Exchange (“NYSE”) and the ordinary shares of Trinseo PLC were listed on the NYSE under the symbol “TSE.” The treasury shares of Trinseo S.A. were cancelled in conjunction with the Redomiciliation. Following the Redomiciliation, we continue to be subject to SEC reporting requirements and the applicable corporate governance rules of the NYSE, and we continue to report ourcondensed consolidated financial ~~results in U.S. dollars and GAAP. As the Redomiciliation was completed subsequent to September 30, 2021, amounts presented herein represent the results of Trinseo S.A. as of and~~statements for ~~the periods ended September 30, 2021 and have not been adjusted for the equity transactions completed in connection with the Redomiciliation on October 8, 2021.~~more information.

Acquisition of ~~Aristech Surfaces~~Heathland

On ~~September 1, 2021,~~January 3, 2022, the Company closed on the previously-announced acquisition of ~~Aristech Surfaces LLC~~Heathland B.V. (“~~Aristech Surfaces”~~Heathland”)~~, a leading North America manufacturer and global provider of PMMA continuous cast and solid surface sheets, serving the wellness, architectural, transportation and industrial markets,~~ for ~~a preliminary~~an estimated purchase price of ~~$449.7~~$29.3 million, including an initial cash purchase price of $22.9 million, subject to customary working capital and other closing adjustments, as well as $6.4 million of contingent cash consideration, representing the fair value of certain earn-out payments (the ~~“Aristech Surfaces~~“Heathland Acquisition”). ~~Aristech Surfaces’ products are used~~Heathland is based in Utrecht, the Netherlands, and is focused on converting post-consumer and post-industrial PMMA, PC, ABS, polystyrene, and other thermoplastic waste for use in a ~~variety~~wide range of ~~applications, including the construction~~high-end applications.

Refer to Note 3 in the condensed consolidated financial statements for more information.

~~Acquisition of the Arkema PMMA Business~~

On May 3, 2021, the Company closed on the previously-announced acquisition of the PMMA and MMA businesses (together, referred to herein as the PMMA business) from Arkema for an initial purchase price consideration of $1,370.7 million, of which $1,369.0 million was paid during the second quarter of 2021, subject to customary working capital and other closing adjustments (the “PMMA Acquisition”). The PMMA Acquisition was funded primarily using proceeds from new debt financing arrangements, as described below. PMMA is a transparent and rigid plastic with a wide range of end uses, and complements Trinseo’s existing offerings across several end markets including automotive, building & construction, medical and consumer electronics. Refer to Note 3 in the condensed consolidated financial statements for further information.

~~Table of Contents~~

~~New Financing Arrangements~~

On March 24, 2021, the Company issued $450.0 million aggregate principal amount of 5.125% senior notes due 2029 (the “2029 Senior Notes”). Further, on May 3, 2021, in conjunction with the closing of the PMMA Acquisition, the Company entered into $750.0 million in incremental term loan borrowings (“2028 Term Loan B”) under our existing senior secured credit facility. The net proceeds from the 2029 Senior Notes and the 2028 Term Loan B, as well as available cash, were used to fund the PMMA Acquisition. Refer to Note 8 in the condensed consolidated financial statements for further details on these new financing arrangements.

~~Divestiture of Synthetic Rubber Business~~

On May 21, 2021, the Company and Synthos PLC and certain of its subsidiaries (together, “Synthos”) entered into an Asset Purchase Agreement, (the “Purchase Agreement”), pursuant to which the Company agreed to sell our Synthetic Rubber business to Synthos in an all-cash transaction with an initial aggregate purchase price of $449.4 million, which reflects a reduction of approximately $41.6 million for the assumption of pension liabilities by Synthos. This initial aggregate purchase price included a working capital target (excluding inventory) of $47.0 million, which was subject to adjustment based on actual amounts conveyed at closing.

On October 21, 2021, the Company and Synthos entered into an amendment to the Purchase Agreement (the “Amended Purchase Agreement”), whereby net working capital (excluding inventory) will not transfer with the sale of the Synthetic Rubber business and, in exchange, the working capital target of $47.0 million will be removed from the purchase price. This will result in an amended purchase price of $402.4 million, subject to certain adjustments related to inventory and the exercise of certain option rights. This amendment had no effect on the intended economics of the sale transaction.

The transaction is expected to close in December of 2021, subject to customary closing conditions. Additionally, Trinseo and Synthos have agreed to enter into a long-term supply agreement, in which we will supply Synthos with certain raw materials used in the Synthetic Rubber business as of the date the transaction closes.

As a result of the above agreements, the assets and liabilities of the Company’s Synthetic Rubber business were classified as held-for-sale starting in the second quarter of 2021 in the condensed consolidated balance sheets and the associated operating results of the Synthetic Rubber business, net of income tax, have been classified as discontinued operations in the condensed consolidated statements of operations and statements of cash flows for all periods presented.

Net Sales

Of the ~~87%~~41% increase in net sales, ~~61%~~26% was attributable to increased selling prices, mainly due to the pass through of higher raw material costs, ~~and 24%~~such as styrene, along with higher energy costs. The majority of the remaining increase was due to ~~the contribution~~contributions from our acquisitions in 2021, including the PMMA Acquisition, which closed on May 3, 2021, and the Aristech Surfaces Acquisition, which closed on September 1, 2021.

Cost of Sales

The ~~92%~~52% increase in cost of sales was primarily attributable to a ~~57%~~23% increase in raw material costs and a 27% increase related to the PMMA Acquisition and Aristech Surfaces ~~Acquisition, and a 5% increase from higher utility costs.~~Acquisition.

These impacts were partially offset by ~~contributions~~additional gross profit from ~~our~~the 2021 acquisitions. See the segment discussion below for further information.

Selling, General and Administrative Expenses (SG&A)

The ~~$30.1~~$40.2 million, or ~~65%~~71%, increase in SG&A was primarily due to ana $19.1 million increase in costs associated with the Company’s strategic initiatives, including the potential divestiture of our Styrenics business, as well as $2.1 million of costs incurred in connection with the Company’s enterprise resource planning system upgrade. Also contributing to the increase was a $10.0 million increase in personnel costs ~~of $12.3 million~~ due to ~~the Company's improved performance during 2021 and~~ the addition of personnel from acquisitions, ~~as well as $10.1~~a $3.4 million increase in additional depreciation and amortization expense from the PMMA Acquisition and the Aristech Surfaces Acquisition, and a $1.6 million increase in bad debt expense. Slightly offsetting these increases was a decrease of $2.8 million related to acquisition transaction and integration costs incurred, primarily in connection with the PMMA ~~Acquisition and the~~Acquisition.

~~Nine Months Ended – September 30, 2021 vs. September 30, 2020~~

Of the $342.3 million, or 253%, increase in net sales, $269.9 million, or 199%, was due to the inclusion of the PMMA business and Aristech Surfaces, following their respective acquisitions during the period. Additionally, there was an increase of 34% from sales volumes, primarily from COVID-19 impacts in the prior year, as well as an increase of 16% due primarily to the pass through of higher raw material costs.

Adjusted EBITDA increased $46.2 million, or 207%, which was almost entirely due to the contribution from the PMMA business and Aristech Surfaces acquisitions. Increases in Adjusted EBITDA from volume gains following negative COVID-19 impacts in the prior year were fully offset by lower margins from higher raw material costs as well as higher fixed costs.

Base Plastics Segment

Our Base Plastics 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 Base Plastics 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.

Higher margins were partially offset by a decrease of ~~$1.1~~$6.8 million, or 3%10%, due to lower volumes, mostly in automotive applications, as supply chain constraints caused by semi-conductor shortages and the Ukraine conflict caused production issues for customers. Also offsetting the higher margins was a decrease of $4.3 million, or 7%, due to foreign exchange impacts, and a decrease of $4.7 million, or 7%, due to higher fixed costs.

Of the 72% increase in net sales, 55% was due to higher pricing from the pass through of raw material costs, primarily styrene. There was also a 12% increase attributable to higher sales volume in applications like construction and automotive where COVID-19 caused production shutdowns in the prior year, as well as a 6% increase due to foreign exchange rate impacts.

The $179.4 million, or 323%, increase in Adjusted EBITDA was primarily due to higher margins of $128.8 million, or 231%, particularly in ABS and PC products. Also contributing was an increase of $32.8 million, or 59%, due to higher sales volume, an increase of $13.7 million, or 25%, due to foreign exchange rate impacts, and an increase of $4.7 million, or 8%, due to lower fixed costs primarily from higher fixed cost absorption in comparison to the prior year.

Three Months Ended – ~~September 30,~~March 31, 2022 vs. March 31, 2021 ~~vs. September 30, 2020~~

Of the ~~64%~~19% increase in net sales, ~~69%~~18% of the increase was due to higher pricing primarily from the pass through of higher styrene costs ~~to our customers. This increase was slightly offset by decreased sales volume of 5%, caused by higher demand in the prior year to COVID-19 essential applications such~~ as ~~packaging.~~well as commercial excellence actions.

The ~~$30.8~~$2.1 million, or ~~151%~~4%, ~~increase~~decrease in Adjusted EBITDA was primarily due to ~~higher margins resulting from commercial excellence initiatives and very tight market conditions, which resulted in an increase~~a decrease of ~~$33.1~~$2.7 million, or ~~162%.~~6%, due to higher fixed costs, and a decrease of $2.3 million, or 5%, due to lower volumes. These effects were partially offset by ~~a decrease of $2.0 million, or 10%, from lower sales volume as noted above.~~

~~Nine Months Ended – September 30, 2021 vs. September 30, 2020~~

~~Of the 69%~~an increase in net sales, 73% of the increase was due to higher pricing primarily from the pass through of higher styrene costs to our customers. This increase was slightly offset by a 4% decrease in sales volume following the high demand in the prior year related to COVID-19 essential applications such as packaging.

~~The $103.2 million, or 222%, increase in Adjusted EBITDA was primarily~~ due to higher margins ~~resulting~~of $1.8 million, or 4%, including impacts from commercial excellence ~~initiatives, strong market conditions, and favorable net raw material timing, which resulted in~~actions, as well as an increase of ~~$109.9~~$1.1 million, or ~~237%. These effects were partially offset by a $4.0 million, or 9%~~2%, ~~decrease attributable to lower sales volume and a $2.6 million, or 6%, decrease~~ due to foreign exchange rate impacts.

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, unsaturated polyethylene resins, and styrene-butadiene rubber.

Three Months Ended – ~~September 30,~~March 31, 2022 vs. March 31, 2021 ~~vs. September 30, 2020~~

The decrease in Adjusted EBITDA was mainly due to ~~headwind from production issues caused by Hurricane Ida~~lower styrene profitability, as a result of lower margins as well as ~~lower styrene~~a production outage in the current period, which was mostly offset by higher polystyrene margins.

~~Nine Months Ended – September 30, 2021 vs. September 30, 2020~~

The increase in Adjusted EBITDA was mainly due to increased sales volume and higher styrene margins in North America, primarily attributable to stronger demand following COVID-19 impacts in the prior year and industry outages caused by weather related and other events.

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;

Table of Contents

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 ~~and nine~~ months ended ~~September 30, 2021~~March 31, 2022 and ~~2020:~~2021:

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.

Operating Activities

Net cash used in operating activities from continuing operations during the three months ended March 31, 2022 totaled $5.2 million. Solid earnings, including $7.5 million of dividends received from Americas Styrenics, were more than offset by a significant working capital build during the quarter. 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.

Net cash provided by operating activities from continuing operations during the ~~nine~~three months ended ~~September 30,~~March 31, 2021 totaled ~~$247.4~~$40.7 million, ~~driven by strong earnings, and~~ inclusive of $15.0 million of dividends received from Americas ~~Styrenics of $60.0 million. Partially offsetting these factors was a $146.0 million reduction~~Styrenics. Net cash used in operating ~~cash from net working capital changes~~assets and liabilities for the three months ended March 31, 2021 totaled $84.5 million, noting an increase in accounts receivable of $138.8 million as well as an increase in inventories of $82.5 million. These effects were partially offset by an increase in accounts payable and other current liabilities of $114.9 million, an increase in other liabilities of $12.3 million, and an increase in income taxes payable of $4.9 million. The increases in accounts receivable, inventories, and accounts payable and other current liabilities during the period ~~which~~ were primarily attributable to ~~increases in~~increased sales volume across all segments except for Feedstocks as well as increased prices, including both raw material ~~costs~~. prices and selling prices due to our pass through pricing arrangements. Net cash ~~used in~~provided by operating activities from discontinued operations during the ~~nine~~three months ended ~~September 30,~~March 31, 2021 totaled ~~$9.2~~$10.3 million, ~~which~~and was ~~also~~ primarily attributable to raw material cost increases and higher inventory related to discontinued operations.

Net cash provided by operating activities from continuing operations during the nine months ended September 30, 2020 totaled $91.2 million. This increase in cash was driven by a $54.6 million increase in operating cash generated from net working capital changes during the period, which were primarily attributable to the Company’s liquidity-focused actions during the period, including reduced capital spending, operating expenses, and working capital, as well as the impact37

Table of lower raw material prices and sales volumes. Net cash provided by operating activities from discontinued operations during the nine months ended September 30, 2020 totaled $36.5 million, and was also driven by the Company’s liquidity-focused actions during the period.Contents

Investing Activities

Net cash used in investing activities from continuing operations during the ~~nine~~three months ended ~~September 30, 2021~~March 31, 2022 totaled ~~$1,885.8~~$46.1 million, which was primarily attributable to net cash paid for asset or business acquisitions of ~~$1,806.6~~$22.2 million (see Note 3), and capital expenditures, including cash spent for our ongoing ERP upgrade, of ~~$64.7 million, and payments for the settlement of hedging instruments of $14.7 million (related to the acquisition purchase price hedge – see Note 10).~~$23.9 million. Net cash used in investing activities from discontinued operations during the ~~nine~~three months ended ~~September 30,~~March 31, 2022 totaled $0.9 million.

Net cash used in investing activities from continuing operations during the three months ended March 31, 2021 totaled ~~$3.3~~$11.2 million, which was entirely attributable to capital expenditures.

~~Table of Contents~~

Net cash provided by investing activities from continuing operations during the nine months ended September 30, 2020 totaled $16.2 million, primarily resulting from proceeds from the settlement of hedging instruments of $51.6 million (see Note 10) as well as proceeds from the sale of businesses and other assets (primarily our land in Livorno, Italy that was sold in January 2020) of $11.9 million. These impacts were partially offset by capital expenditures of $47.4 million, which management has taken specific actions to control and reduce in response to COVID-19. Net cash used in investing activities from discontinued operations during the ~~nine~~three months ended ~~September 30, 2020~~March 31, 2021 totaled ~~$13.5~~$1.4 million, which was entirely attributable to capital expenditures.

Financing Activities

Net cash ~~provided by~~used in financing activities during the ~~nine~~three months ended ~~September 30, 2021~~March 31, 2022 totaled ~~$1,272.8~~$70.6 million. This activity was primarily due to $746.3 million in proceeds from the issuance of the 2028 Term Loan B, $450.0 million in proceeds from the issuance of the 2029 Senior Notes, $120.0 million in net proceeds from a draw on the Accounts Receivable Securitization Facility, and $10.5 million in proceeds from exercise of option awards. This activity was partially offset by $35.0$51.9 million of ~~deferred financing fees primarily~~payments related to the ~~issuance~~repurchase of ~~our 2028 Term Loan, $11.6~~ordinary shares, $12.4 million of dividends paid, $3.6 million of net repayments of short-term borrowings, ~~$9.5 million of dividend payments,~~ and ~~$7.1~~$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.

Net cash ~~used in~~provided by financing activities during the ~~nine~~three months ended ~~September 30, 2020~~March 31, 2021 totaled ~~$85.1~~$450.8 million. This activity was primarily due to ~~$46.5~~$450.0 million in proceeds from the issuance of the 2029 Senior Notes as well as $9.0 million in proceeds from the exercise of option awards. This activity was partially offset by $3.3 million of dividends ~~paid, $25.0 million of~~ payments, ~~related to the repurchase of ordinary shares, $8.2~~$2.8 million of net repayments of short-term borrowings, and ~~$5.2~~$1.3 million of ~~net principal payments~~deferred financing fees related to the issuance of our ~~2024 Term Loan B~~2029 Senior Notes 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.

~~As of September 30, 2021~~At March 31, 2022 and December 31, ~~2020,~~2021, we had ~~$2,503.7~~$2,365.2 million and ~~$1,187.3~~$2,368.8 million, respectively, in outstanding indebtedness and ~~$703.7~~$1,045.9 million and ~~$905.7~~$1,064.1 million, respectively, in working capital (calculated as current assets from continuing operations less current liabilities from continuing operations). In addition, as of ~~September 30, 2021~~March 31, 2022 and December 31, ~~2020,~~2021, we had ~~$121.4~~$445.0 million and ~~$172.8~~$560.6 million, respectively, of foreign cash and cash equivalents on our balance sheet, outside of our country of domicile, ~~of Luxembourg~~which was Ireland as of ~~September 30, 2021,~~March 31, 2022, 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.

As discussed in Note 8 of the condensed consolidated financial statements, the Company completed a senior note issuance during the first quarter of 2021, and both borrowed a new tranche of term loans and refinanced our revolving credit facility during the second quarter of 2021. Additionally, during the third quarter of 2021, the Company drew on our Accounts Receivable Securitization Facility and extended the maturity of the facility. The results of the changes to our financing arrangements during the nine months ended September 30, 2021 are reflected in the table below.

The following table outlines our outstanding indebtedness as of ~~September 30, 2021~~March 31, 2022 and December 31, ~~2020~~2021 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 the ~~nine~~three months ended ~~September 30, 2021,~~March 31, 2022, interest expense on “Other indebtedness” totaled less than $0.1 million.

As of ~~September 30, 2021,~~March 31, 2022, 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. As of ~~September 30, 2021,~~March 31, 2022, the Company had ~~$366.9~~$368.6 million of funds available for borrowing (net of ~~$8.1~~$6.4 million outstanding letters of credit) under the 2026 Revolving Facility. Further, as of ~~September 30, 2021,~~March 31, 2022, 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), each of which requires scheduled quarterly payments in amounts equal to 0.25% of the original principal. The stated interest rate on our 2024 Term Loan B is London Interbank Offered Rate (“LIBOR”) plus 2.00% (subject to a 0.00% LIBOR floor). The stated interest rate on our 2028 Term Loan B is LIBOR plus 2.50% (subject to a 0.00% LIBOR floor). The Company made net principal payments of $5.2 million on the 2024 Term Loan B and net principal payments of $1.9 million on the 2028 Term Loan B during the nine months ended September 30, 2021, with an additional $14.5 million of scheduled future payments classified within current debt on the Company’s condensed consolidated balance sheet as of September 30, 2021 related to both the 2024 Term Loan B and 2028 Term Loan B.

Our ability to raise additional financing and our borrowing costs may be impacted by short- and long-term debt 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 ~~nine~~three months ended ~~September 30, 2021,~~March 31, 2022, the Company declared dividends of ~~$0.48~~$0.32 per ordinary share, totaling ~~$19.0~~$12.1 million, all of which ~~$13.7 million~~ was accrued as of ~~September 30, 2021~~March 31, 2022 and which was paid in ~~October 2021.~~April 2022. 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.

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 the risk factors included in Part II, Item 1A herein. As of ~~September 30, 2021,~~March 31, 2022, 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.

~~Table~~The ongoing war in Ukraine and the corresponding sanctions and other measures being imposed by various governments have impacted global markets, particularly in Europe, leading to: (i) high volatility and increasing prices for natural gas and other energy supplies, (ii) changing trade flow patterns, and (iii) increasing levels of ~~Contents~~economic and geopolitical uncertainty globally. We do not have manufacturing operations in Ukraine, Russia or Belarus, and we have temporarily suspended sales and deliveries to Russia and Belarus, which sales do not constitute a material portion of our business. However, a significant escalation or expansion of economic disruption caused by this conflict, including supply disruptions, higher costs of raw materials or energy could have a material adverse effect on our results of operations, financial condition and cash flows. We are actively monitoring the broader economic impact from the crisis, in particular on the price and availability of raw materials and energy.

Contractual Obligations and Commercial Commitments

During the first and second quarter of 2021, the Company entered into new financing arrangements in connection with our acquisition of Arkema’s PMMA business, including the $450.0 million 2029 Senior Notes issued on March 24, 2021 and the $750.0 million 2028 Term Loan B entered into on May 3, 2021 upon closing of the transaction. Refer to Notes 3 and 8 of the condensed consolidated financial statements and the “Capital Resources and Liquidity” section of Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations for details on these contractual obligations entered into subsequent to December 31, 2020.

Additionally during the second quarter of 2021, the Company entered into a long-term contract to purchase benzene directly from Dow Europe’s facilities for use at the Company’s Terneuzen location. This contract has a term of two years with an automatic two-year renewal provision, and contains annual minimum purchase and maximum sale volume commitments.

There have been no ~~other~~ 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.

Table of Contents

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

~~Table of Contents~~

participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company’s disclosure controls and procedures as of ~~September 30, 2021.~~March 31, 2022. 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

As discussed in Note 3 to the condensed consolidated financial statements, in May 2021, the Company completed the acquisition of the Arkema PMMA business and in September 2021, the Company completed the acquisition of Aristech Surfaces. As permitted by the SEC, management has elected to exclude these acquisitions from its assessment of the effectiveness of its internal control over financial reporting as of December 31, 2021. The Company began to integrate each of these businesses into our internal control over financial reporting structure subsequent to the acquisition dates and expects to complete these integrations within one year of the respective acquisitions.

~~Aside from the acquisition-related changes discussed above, there have been~~There was 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 ~~September 30, 2021~~March 31, 2022 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. WeOther than the European Commission request for information described in Note 13 – Commitments and Contingencies, we currently believe that there is no litigation pending that is likely to have a material adverse effect on 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 material developments in legal proceedings during the quarter ended March 31, 2022, see “Litigation Matters” and “European Commission Request for Information” in Note 13 to our condensed consolidated financial statements.

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, ~~2020.~~2021. 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. ~~Production at our manufacturing facilities could be disrupted for a variety of reasons. Disruptions could expose us to significant losses or liabilities.~~

Risks Related to ~~Acquisitions and Dispositions~~Our Operations

~~We may fail to realize~~Volatility in the ~~anticipated benefits~~cost of raw materials, logistics services, energy, or transportation utilized for our products, or disruption in the supply of the ~~PMMA Acquisition~~raw materials utilized for our products, may adversely affect our financial condition and results of operations or ~~such benefits may take longer~~cause our financial results to ~~realize than expected. We may also encounter difficulty integrating~~differ materially from our forecasts.

Our results of operations can be directly affected, positively and negatively, by volatility in the ~~PMMA business into our operations.~~

~~On May 3, 2021, we announced the closing~~cost of our ~~acquisition from Arkema PLC (“Arkema”)~~raw materials, which are subject to global supply and demand and other factors beyond our control. Our principal raw materials (benzene, ethylene, butadiene, BPA, MMA, and styrene) together represent approximately 81% of ~~its polymethyl methacrylates (“PMMA”)~~our total cost of goods sold. Additionally, we use natural gas and ~~activated methyl methacrylates (“MMA”) businesses (together, referred~~electricity to ~~herein as~~operate our facilities and generate heat and steam for our various manufacturing processes. Crude oil prices also impact our raw material and energy costs. Generally, higher crude oil prices lead to higher costs of natural gas and raw materials, although some raw materials are impacted less than others.

We believe that rapid changes in pricing also can affect the ~~anticipated benefits of the PMMA Acquisition will depend on~~volume our ~~ability to integrate the PMMA business into ours. Combining these businesses will be a complex and time-consuming process.~~customers consume. As a result, our gross profit and margins could also be adversely affected and our financial results may differ materially from our forecasts. The ongoing war in Ukraine has impacted global energy markets, particularly in Europe, leading to high volatility and increasing prices for crude oil, natural gas and other energy supplies. In the event that the supply of natural gas from Russia stops or is significantly reduced, there may be supply disruptions, increased prices or rationing of energy supply within countries in which we ~~expect~~do business which could have a material adverse impact on our business or results of operations in those countries.

We are dependent on third-party freight carriers to ~~devote significant attention~~transport many of our products.

We have supply agreements with Dow for ethylene, benzene, butadiene, and MMA, which are critical raw materials to our business. These raw materials and other less critical materials amount to approximately 22% of our total raw materials acquired ~~PMMA business. This integration process~~in 2021, based on aggregate purchase price. The remainder is purchased via other third-party suppliers on a global basis. As these and other third-party supply agreements expire, we may be ~~disruptive~~unable to renegotiate or renew these contracts, or obtain new long-term supply agreements on terms comparable or favorable to us, or at all, which may significantly impact our ~~ongoing~~operations. See Part 1, Item 1—Business— Sources and Availability of Raw Materials of our Annual Report for the year ended December 31, 2021 for additional information.

If the availability of any of our principal raw materials is limited, we may be unable to produce some of our products in the quantities demanded by our customers, which could have an adverse effect on plant utilization and our sales of products requiring such raw materials. Suppliers may have temporary limitations preventing them from meeting our requirements, and we may not be able to obtain substitute alternative suppliers in a timely manner or on favorable terms.

business, and, if we fail to effectively integrate, or if integration takes longer or is more costly than expected, we could lose or diminish the expected benefits of the PMMA Acquisition. Even if we are able to integrate the PMMA business successfully, this integration may not result in the realization of the synergies and benefits that we currently expect, nor can we give assurances that these benefits will be achieved when expected or at all.

We also face risks that we fail to meet our financial and strategic goals, due to, among other things, inability to grow and manage growth profitability, maintain relationships with customers or retain key employees. We may also be adversely affected by other economic, business, and/or competitive factors which may not have existed at the time of closing. Such conditions could materially adversely impact our business and results of operations.

~~We face risks concerning our acquisition of Aristech Surfaces, and may fail to realize the anticipated benefits of the Aristech Surfaces acquisition.~~

In September 2021, we completed the acquisition of the issued and outstanding membership interests of Aristech Surfaces. We may face difficulties realizing the anticipated benefits of the acquisition. We may fail to realize anticipated cost and revenue synergies from the transaction, reach expected margins, and we may not be successful in expanding or growing the business profitability. We may also fail to maintain relationships with customers or retain and integrate the employees of Aristech Surfaces. Aristech Surfaces may also be adversely affected by other economic, business, and/or competitive factors which may not have existed at the time of closing. Such conditions could materially adversely impact our business and results of operations.

Risks Related to ~~Our Indebtedness~~Regulation

~~Our current and future level of indebtedness~~Trinseo Europe GmbH, one of our subsidiaries, ~~including~~received a Request for Information from the ~~incurrence~~European Commission Directorate General for Competition, involving commercial activity for styrene monomer. To the extent the European Commission’s inquiry would lead to a finding that the Company’s subsidiary violated the law, the results of ~~additional indebtedness~~this finding could have a material adverse effect on our business, financial condition, results of operations, and cash flows.

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 ~~fund~~styrene monomer commercial activity in the ~~PMMA Acquisition, could adversely affect our financial condition.~~European Economic Area. In addition, the Company commenced an internal investigation into the matter and has discovered instances of inappropriate activity. We have provided all information requested and continue to fully cooperate with the Request for Information.

As a result of ~~December~~further developments in this matter, during the three months ended March 31, ~~2020, our indebtedness totaled approximately $1.2 billion. Additionally, as~~2022, the Company recorded a reserve for an estimated liability of ~~December 31, 2020, we had $360.0~~$35.6 million, (net of $15.0 million outstanding letters of credit) of funds available for borrowings under our Senior Credit Facility, as well as $150.0 million of funds available for borrowings under our accounts receivable securitization facility (the “Accounts Receivable Securitization Facility”).

~~Additionally, in connection with~~which remains ongoing and the PMMA Acquisition, our Trinseo Materials Operating S.C.A. and Trinseo Materials Finance Inc. subsidiaries issued $450.0 million principal amount of 5.125% Senior Notes due 2029 (the “2029 Senior Notes”) and borrowed an additional $750.0 million in term loans under our Senior Credit Facility, the proceedsoutcome of which ~~were used~~remains unknown. Trinseo Europe GmbH may be subject to ~~pay~~fines and/or certain behavioral or structural commitments imposed by the European Commission. If Trinseo Europe GmbH is found to have violated one or more laws, it could also be subject to additional actions by local competition authorities. European Commission inquiries or investigations can continue over a ~~portion~~long period of time, which can divert the ~~purchase price of the PMMA Acquisition.~~

~~Our current level of indebtedness, as well as future borrowings or other indebtedness, could have significant consequences for our business, including but not limited to:~~

●

~~increasing our vulnerability to economic downturns and adverse industry, competitive, or market conditions;~~

●

requiring a substantial portion of our cash flows from operations to be dedicated to the payment of principal and interest on our indebtedness, therefore reducing our ability to use our cash flow to fund capital expenditures and future business opportunities and returning cash to our shareholders in the form of dividends or share repurchases;

●

~~limiting our ability to obtain additional financing for working capital, capital expenditures, acquisitions, and general corporate or other purposes;~~

●

compromising our flexibility to capitalize on business opportunities or other strategic acquisitions, and to react to competitive pressures, as compared to our competitors, or forcing us to make nonstrategic divestitures;

●

~~placing us at a disadvantage compared to other, less leveraged competitors or competitors with comparable debt at more favorable interest rates; and~~

●

~~increasing our cost of borrowing.~~

~~Although the terms~~attention of our ~~senior secured credit agreement (the “Credit Agreement”) governing~~management from day-to-day operations and impose significant administrative burdens. Any of these consequences could damage our ~~senior secured financing facility of up to $1,075.0 million (the “Senior Credit Facility”),~~reputation and ~~the note indentures governing~~ ~~the 2029 Senior Notes and our~~ ~~5.375% senior notes due 2025~~ ~~(the “Indentures”), contain restrictions on the incurrence of~~

~~Table of Contents~~

additional indebtedness, these restrictions are subject to a number of qualifications and exceptions and the indebtedness incurred in compliance with these restrictions could be substantial. Also, we are not prevented from incurring obligations that do not constitute “indebtedness” as defined in the Senior Credit Facility or the Indentures, such as operating leases and trade payables. If new debt is added to our subsidiaries’ current debt levels, the risks related to indebtedness that we now face could intensify.

In addition, a substantial portion of our subsidiaries’ current indebtedness is secured by substantially all of our assets, which may make it more difficult to secure additional borrowings at reasonable costs. If we default or declare bankruptcy, after these obligations are met, there may not be sufficient funds or assets to satisfy our subordinate interests, including those of our shareholders.

~~The terms of our subsidiaries’ indebtedness may restrict our current and future operations, particularly~~impair our ability to ~~respond to change or to take certain actions.~~

~~The Indentures and the Credit Agreement governing our Senior Credit Facility contain~~conduct business, which could have a ~~number of covenants imposing certain restrictions~~material adverse effect on our ~~subsidiaries’ businesses. These restrictions may affect our ability to operate our~~ business, financial condition, results of operations, and ~~may limit our ability to take advantage of business opportunities. These agreements restrict, among other things, our subsidiaries’ ability to:~~

●

~~sell or assign assets;~~

●

~~incur additional indebtedness;~~

●

~~pay dividends to Trinseo PLC;~~

●

~~make investments or acquisitions;~~

●

~~incur liens;~~

●

~~repurchase or redeem capital shares;~~

●

~~engage in mergers or consolidations;~~

●

~~materially alter the business they conduct;~~

●

~~engage in transactions with affiliates; and~~

●

~~consolidate, merge or transfer all or substantially all of their assets.~~

The ability of our subsidiaries to comply with the covenants and financial ratios and tests contained in the Indenture and Credit Agreement, to pay interest on indebtedness, fund working capital, and make anticipated capital expenditures depends on our future performance, which is subject to general economic conditions and other factors, some of which are beyond our control. There can be no assurance that our business will generate sufficient cash flow from operations or that future borrowings will be available under our Senior Credit Facility to fund liquidity needs in an amount sufficient to enable them to service their indebtedness. Furthermore, if we need additional capital for general corporate purposes or to execute on an expansion strategy, there can be no assurance that this capital will be available on satisfactory terms or at all.

A failure to repay amounts owed under the Senior Credit Facility, or the notes issued under our Indentures, at maturity would result in a default. In addition, a breach of any of the covenants in the Credit Agreement or Indentures or our inability to comply with the required financial ratios or limits could result in a default. If a default occurs, lenders may refuse to lend us additional funds and the lenders or noteholders could declare all of the debt and any accrued interest and fees immediately due and payable. A default under one of our subsidiaries’ debt agreements may trigger a cross-default under our other debt agreements.
