Rhea-AI Filing Summary

Trinseo PLC reported weaker first quarter 2026 results, with net sales of $724.7 million, down 8% from the prior year as lower prices and volumes more than offset favorable currency effects. The company recorded a net loss of $115.9 million, compared with a $79.0 million loss a year earlier, as higher interest expense and restructuring-related costs weighed on results.

Adjusted EBITDA was $52.6 million, down from $64.8 million, reflecting the absence of prior-year technology licensing income, partly offset by savings from restructuring actions. Cash used in operating activities was $232.9 million, and together with capital expenditures this led to Free Cash Flow of negative $244.2 million, driven by seasonality, tighter trade credit and higher raw material costs. The balance sheet shows cash and cash equivalents of $110.6 million and shareholders’ deficit of $1.22 billion as of March 31, 2026.

Positive

  • None.

Negative

  • Net loss and per-share results deteriorated: Q1 2026 net loss widened to $115.9 million and diluted EPS declined to $(3.20) from $(2.22), reflecting higher interest expense and additional restructuring-related costs.
  • Significant cash burn and free cash flow deficit: Cash used in operating activities was $232.9 million and Free Cash Flow was $(244.2) million in Q1 2026, highlighting substantial near-term liquidity pressure.
  • Highly leveraged, negative equity balance sheet: As of March 31, 2026, shareholders’ equity stood at $(1.22) billion, with large current liabilities and meaningful interest expense, underscoring a strained capital structure and elevated financial risk.

Insights

Trinseo shows deepening losses, heavy cash burn and a highly leveraged capital structure.

Trinseo generated Q1 2026 net sales of $724.7 million, down 8% year over year as prices fell 9% and volumes declined 4%, partially offset by a 5% favorable currency impact. Gross profit held near flat, but operating performance remained weak, with an operating loss of $23.6 million.

Financing costs are a major pressure point. Net interest expense of $78.7 million exceeded operating loss, contributing to a net loss of $115.9 million and Adjusted Net Loss of $74.6 million. Management also cites ongoing lender negotiations and restructuring programs, and forward-looking statements reference risks around indebtedness, covenant compliance, liquidity and even the ability to continue as a going concern.

Liquidity and leverage are key concerns. Cash used in operating activities was $232.9 million, and Free Cash Flow was $(244.2) million for the quarter. As of March 31, 2026, cash and cash equivalents were $110.6 million, while the balance sheet shows substantial current liabilities and shareholders’ deficit of $1.22 billion. Subsequent filings may provide more detail on lender discussions, refinancing progress and any asset sale outcomes such as the potential sale of the Americas Styrenics interest.

Adjusted EBITDA financial
"Adjusted EBITDA of $53 million was $12 million below prior year"
Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.
Free Cash Flow financial
"Free Cash Flow* of negative $244 million. Free cash flow was affected by three primary factors"
Free cash flow is the amount of money a company has left over after paying all its expenses and investing in its business, like buying equipment or updating facilities. It shows how much cash is available to reward shareholders, pay down debt, or save for future growth. This helps investors understand if a company is financially healthy and able to grow.
Americas Styrenics financial
"the timing of, and our ability to complete, a sale of our interest in Americas Styrenics"
Accounts Receivable Securitization Facility financial
"Proceeds from Accounts Receivable Securitization Facility | 22.0"
A accounts receivable securitization facility is a financing arrangement where a company converts its unpaid customer invoices into immediate cash by selling them or using them as collateral for a line of credit. Think of it like using a stack of IOUs as a short-term loan to smooth cash flow; it matters to investors because it changes a company’s liquidity, borrowing profile and risk exposure without necessarily showing up as traditional debt, affecting valuation and credit health.
2028 Refinance Term Loans financial
"Net proceeds from issuance of 2028 Refinance Term Loans | 115.0"
going concern financial
"Factors that might cause future results to differ include our ability to continue as a going concern"
A going concern is a business that is expected to continue its operations and meet its obligations for the foreseeable future, rather than shutting down or selling off assets. This assumption matters to investors because it indicates stability and ongoing profitability, making the business a more reliable investment. Think of it as believing a restaurant will stay open and serve customers, rather than closing down suddenly.

WAYNE, Pa — April 30, 2026 — Trinseo a specialty material solutions provider, today reported its first quarter 2026 financial results. Net sales of $725 million decreased 8% compared with the prior year, driven by 9% lower prices across all business segments due to competitive pressures and lower raw material costs and 4% decrease from volumes, partially offset by a 5% favorable currency impact. First quarter net loss of $116 million was $37 million lower than prior year. The current year quarter included $31 million of pre-tax charges primarily related to costs incurred in connection with ongoing lender negotiations and asset restructuring programs. Adjusted EBITDA of $53 million was $12 million below prior year, driven by $26 million of polycarbonate technology licensing income in the prior year, partially offset by savings from previously announced restructuring actions.

First quarter cash used in operating activities of $233 million and capital expenditures of $11 million led to Free Cash Flow* of negative $244 million. Free cash flow was affected by three primary factors – typical first quarter seasonality, a contraction in trade credit from suppliers and other counterparties, and higher raw material costs.

First Quarter Results and Commentary by Business Segment

Engineered Materials net sales of $263 million for the quarter decreased 5% versus prior year primarily due to lower prices and lower MMA volumes following the closure of our virgin MMA production facilities in Italy. Adjusted EBITDA of $34 million increased $8 million versus prior year due to savings from closing our aforementioned MMA facilities, share gain in PMMA products in Europe, and strategic margin expansion initiatives in our surfaces products in North America.
Latex Binders net sales of $197 million for the quarter decreased 6% versus prior year from lower prices, primarily in paper and board and textile applications globally. Adjusted EBITDA of $16 million was $8 million below prior year from weak demand and low margins in paper and board and textile applications mainly in Europe. Net sales to CASE and battery binders applications accounted for 19% of total segment net sales, with volume increasing 14% over prior year in a soft market environment.
Polymer Solutions net sales of $265 million for the quarter decreased 11% versus prior year from lower prices and lower polystyrene volumes. Adjusted EBITDA of $24 million was $20 million below prior year, primarily due to $26 million of polycarbonate licensing income in the prior year, partially offset by mix improvement. The favorable mix stems from higher ABS volumes in North America from share gain, which were offset by lower polystyrene volumes in Europe due to strategically optimized customer mix.
Americas Styrenics Adjusted EBITDA of $2 million for the quarter was $4 million above prior year from stronger styrene and polystyrene performance.

Commenting on the Company’s first quarter performance, Frank Bozich, President and Chief Executive Officer of Trinseo, said, “Amidst dynamic market and macroeconomic conditions during the first quarter, our team demonstrated remarkable resilience. We continued to build for the future across our priority areas like battery binders, CASE, PMMA, Asia, and recycled content containing platforms to drive profitable, sustainable growth. I am grateful for the dedication and impact of our entire workforce, who have demonstrated their commitment throughout this quarter. Our mission remains clear: deliver unmatched materials and service excellence for our customers, while navigating significant geopolitical uncertainty.”

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.

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.

(a)During the three months ended March 31, 2026, the Company recognized $9.2 million for accelerated amortization of capitalized software assets related to our current ERP system which is being transitioned to a cloud-based system.

During the three months ended March 31, 2025, an $8.1 million benefit was recognized due to a change in cost estimate related to the Boehlen, Germany asset retirement obligation as the Company was able to realize efficiencies during decommissioning.

(b)Amounts for the three months ended March 31, 2025 primarily relate to fees incurred in conjunction with Company’s debt refinancing transaction that did not meet the criteria for deferred financing charges.
(c)Amounts for the three months ended March 31, 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 2026 period primarily relate to costs incurred in connection with ongoing lender negotiations. Other items for the 2025 period primarily relate to fees incurred in conjunction with certain of the Company’s strategic initiatives, including the potential divestiture of our styrenics business.
(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 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 March 31, 2026 and 2025 exclude accelerated depreciation of $10.9 million and $9.4 million, respectively. The 2026 period charges are primarily related to the shortening of the useful life of certain IT assets in preparation to move to a cloud hosted platform.

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.
