Exhibit 99.1

Unaudited Pro Forma Combined Financial Information

The unaudited pro forma combined statement of operations for the year ended December 31, 2020, gives effect to the Transactions as if they had been consummated on January 1, 2020. The unaudited pro forma combined balance sheet as of December 31, 2020 gives effect to the Transactions as if they had been consummated on December 31, 2020.

The unaudited pro forma combined balance sheet as of December 31, 2020 and pro forma combined statement of operations for the year ended December 31, 2020 were derived from (i) the audited consolidated financial statements of Trinseo for the year ended December 31, 2020, and (ii) the audited combined carve-out financial statements of the Arkema business for the year ended December 31, 2020, both of which are included elsewhere in this Offering Memorandum.

The pro forma adjustments consist of transaction accounting adjustments reflecting (i) the exclusion of the South Korea site and related operations, which are included in the historical results of the Arkema business but are not included in the scope of the contemplated PMMA Acquisition (“Excluded South Korea Business”) and (ii) the impact of the PMMA Acquisition (“Acquisition Pro Forma Adjustments”), and other transaction accounting adjustments related to the consummation of the Offering of the Notes and the offering of the Incremental Term Loan Facility, (together, “Financing Pro Forma Adjustments”). Autonomous entity adjustments and management adjustments were not reflected in the unaudited pro forma combined financial information.

Assumptions underlying the pro forma adjustments are described in the accompanying notes, which should be read in conjunction with the unaudited pro forma combined financial information. Management believes that these assumptions and adjustments are reasonable and appropriate under the circumstances and are factually supported based on information currently available.

The unaudited pro forma combined financial information has been prepared without full access to the books and records of the PMMA business, and thus we have only completed preliminary valuations to estimate the fair value of the assets and the liabilities to be acquired in the PMMA Acquisition, and the related allocation of purchase price. A final determination of the fair value of assets and liabilities acquired will be based on the actual net tangible and intangible assets and liabilities of the PMMA business that exist as of the acquisition date if and when completed. Therefore, certain pro forma adjustments, such as recording fair value of assets and liabilities, conversion of the basis of the PMMA business’ financial information from IFRS, as issued by the IASB, to GAAP, and adjustments for consistency of accounting policies, are preliminary in this unaudited pro forma combined financial information and subject to further adjustments as additional information becomes available and as additional analyses are performed. As the final valuations are performed, increases or decreases in the fair value of relevant balance sheet amounts and their useful lives will result in adjustments, which may be material to the balance sheet and/or the statement of operations.

The unaudited pro forma combined financial information is for illustrative and informational purposes only and is not intended to represent, or be indicative of, what our financial position or results of operations will be for any future period or as of any future date. The unaudited pro forma combined financial information does not reflect any integration costs or savings that may be realized from the Transactions. The unaudited pro forma combined financial information presented below is not necessarily indicative of future results and should be read in conjunction with our sections entitled “Risk Factors,” “The Transaction,” “Use of Proceeds,” “Capitalization,” Selected Financial Information,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” our audited consolidated financial statements for the fiscal year ended December 31, 2020 and the notes thereto included in this Offering Memorandum, and the Arkema business’ audited combined carve-out financial statements for the year ended December 31, 2020, and the notes thereto included in this Offering Memorandum.
