2 WAYNE, Pa — August 6, 2026 — Trinseo, a specialty material solutions provider, today reported its second quarter 2026 financial results. Net sales of $845 million increased 8% compared with the prior year, driven by higher prices across all business segments due to pass-through of higher raw material costs, commercial initiatives, and favorable currency impacts. These increases were partially offset by lower volumes, which were entirely attributable to the closure of our virgin MMA production facilities in Italy and the force majeure at our polystyrene plant in Tessenderlo caused by operational damage from a severe storm. Second quarter net loss of $120 million was $14 million worse than prior year. The current year quarter included $89 million of pre-tax charges, primarily related to reorganization items and other debt restructuring costs, as well as asset restructuring programs. Adjusted EBITDA of $81 million was $39 million above prior year, primarily from margin improvements in Polymer Solutions and Engineered Materials and savings from previously announced asset restructuring actions. Second quarter cash used in operating activities of $115 million and capital expenditures of $10 million led to Free Cash Flow* of negative $125 million. Free cash flow was impacted by debt and other restructuring fees of $85 million and volatile raw material costs which led to a working capital increase of $80 million. During the quarter, the Company continued to advance its debt restructuring process and maintain ordinary-course operations supported by court-approved DIP financing. Trinseo remains focused on serving customers, supporting suppliers and employees, and executing its financial restructuring to strengthen its balance sheet and improve long-term financial flexibility. Second Quarter Results and Commentary by Business Segment ● Engineered Materials net sales of $292 million for the quarter decreased 1% versus prior year primarily due to lower MMA volumes following the closure of our virgin MMA production facilities in Italy. Adjusted EBITDA of $43 million increased $12 million versus prior year due to global margin expansion as a result of strategic product mix improvements from lower MMA volumes and higher PMMA resin volumes, as well as lower fixed costs driven by savings from the closure of the aforementioned MMA facilities. ● Latex Binders net sales of $248 million for the quarter increased 21% versus prior year from higher prices and volumes, primarily in paper and board and textile applications in Asia and North America. Adjusted EBITDA of $16 million was $1 million below prior year due to continued weakness in paper & board and textile applications in Europe as well as negative net timing. Net sales to CASE and battery binders applications accounted for 15% of total segment net sales, with volume increasing 3% over prior year in a muted market environment. ● Polymer Solutions net sales of $306 million for the quarter increased 7% versus prior year from higher prices, partially offset by lower volumes primarily in polystyrene due to our Tessenderlo site’s force majeure from the end of March to the beginning of May. Plant operations were fully restored by the end of May. Adjusted EBITDA of $43 million was $38 million above prior year, primarily due to margin improvement from raw material volatility and commercial initiatives, partially offset by lower polystyrene volumes. ● Americas Styrenics Adjusted EBITDA of $1 million for the quarter was $7 million below prior year from higher raw material costs, mainly benzene, and soft end market demand. Commenting on the Company’s second quarter performance, Frank Bozich, President and Chief Executive Officer of Trinseo, said, “The second quarter has been characterized by volatile market conditions and persistent consumer uncertainty amidst significant ongoing geopolitical tensions, however our team has remained focused and taken proactive steps to take advantage of opportunities where they arise. We continue to focus on strategic product and market growth, while delivering world-class service to our customers and maintaining strong relationships with our suppliers. We are also encouraged by the progress made in our balance sheet restructuring process, which is supported by our court-approved DIP financing and allows us to continue operating in the ordinary course.

3 Use of non-GAAP measures In addition to using standard measures of performance and liquidity that are recognized in accordance with accounting principles generally accepted in the United States of America (“GAAP”), we use additional measures of income excluding certain GAAP items (“non-GAAP measures”), such as Adjusted Net Income (Loss), EBITDA, Adjusted EBITDA and Adjusted EPS and measures of liquidity excluding certain GAAP items, such as Free Cash Flow. We believe these measures are useful for investors and management in evaluating business trends and performance each period. These measures are also used to manage our business and assess current period profitability, as well as to provide an appropriate basis to evaluate the effectiveness of our pricing strategies. Such measures are not recognized in accordance with GAAP and should not be viewed as an alternative to GAAP measures of performance or liquidity, as applicable. The definitions of each of these measures, further discussion of usefulness, and reconciliations of non-GAAP measures to GAAP measures are provided in the Notes to Condensed Consolidated Financial Information presented herein.

As such, we do not separately report net sales of Americas Styrenics within our condensed consolidated statements of operations. Note 2: Reconciliation of Non-GAAP Performance Measures to Net Income EBITDA is a non-GAAP financial performance measure, which is defined as income from continuing operations before interest expense, net; income tax provision; depreciation and amortization expense. We refer to EBITDA in making operating decisions because we believe it provides our management as well as our investors 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. We also present Adjusted EBITDA as a non-GAAP financial performance measure, which we define as income from continuing operations before interest expense, net; income tax provision; 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. 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. Lastly, we present Adjusted Net Income (Loss) and Adjusted EPS as additional performance measures. Adjusted Net Income (Loss) is calculated as Adjusted EBITDA (defined beginning with net income from continuing operations, above), less interest expense, less the provision for income taxes and depreciation and amortization, tax affected for various discrete items, as appropriate. Adjusted EPS is calculated as Adjusted Net Income (Loss) per weighted average diluted shares outstanding for a given period. We believe that Adjusted Net Income (Loss) and Adjusted EPS provide transparent and useful information to management, investors, analysts and other stakeholders in evaluating and assessing our operating results from period-to-period after removing the impact of certain transactions and activities that affect comparability and that are not considered part of our core operations. There are limitations to using the financial performance measures noted above. These performance measures are not intended to represent net income or other measures of financial performance. As such, they should not be used as alternatives to net income as indicators of operating performance. Other companies in our industry may define these performance measures differently than we do. As a result, it may be difficult to use these 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 these performance measures to our net income, which is determined in accordance with GAAP.

(b) Amounts for the three ended June 30, 2026 primarily relate to fees incurred in conjunction with the Company’s ongoing lender negotiations that did not meet the criteria for deferred financing charges as the transaction occurred during the Chapter 11 proceedings and was accounted for in accordance with ASC 852. Amounts for the three months ended June 30, 2025 primarily relate to fees incurred in conjunction with Company’s debt refinancing transaction that did not meet the criteria for deferred financing charges as the transaction was accounted for as a modification of debt in accordance with ASC 470-60. (c) Amounts for the three months ended June 30, 2026 primarily relate to gain on sale of assets after certain of the Company’s restructuring plans. (d) Restructuring and other charges for the 2026 and 2025 periods primarily relate to employee termination benefits, contract termination costs as well as decommissioning and other charges incurred in connection with the Company’s restructuring plans. (e) Other items for the three ended June 30, 2026 primarily relate to fees incurred in connection with the Company’s ongoing lender negotiations which were incurred before the Company filed for bankruptcy or were incurred by non- Debtor entities. Any fees incurred in connection with the Company’s ongoing lender negotiations by the Debtors during the pendency of the bankruptcy are included in Reorganization items, net. Other items for the 2025 period primarily relate to fees incurred in conjunction with certain of the Company’s legal defense costs associated with Synthos litigation. (f) Adjusted to remove the tax impact of the items noted within the table above. The income tax expense (benefit) related to these items was determined utilizing either (1) the estimated annual effective tax rate on our ordinary income based upon our

9 forecasted ordinary income for the full year or, (2) for items treated discretely for tax purposes we utilized the applicable rates in the taxing jurisdictions in which these adjustments occurred. (g) Amounts for the three months ended June 30, 2026 and 2025 exclude accelerated depreciation of $2.0 million and $14.9 million, respectively. The 2026 and 2025 charges are primarily related to the depreciation impacts related to restructuring programs. Note 3: Reconciliation of Non-GAAP Liquidity Measures to Cash from Operations The Company uses certain measures, such as Free Cash Flow as non-GAAP measures, to evaluate and discuss its 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 indicators 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 alternatives 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. The Company compensates for these limitations by providing the following detail, which is determined in accordance with GAAP.
