Welcome to our dedicated page for Trinseo Plc SEC filings (Ticker: TSE), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
Trinseo PLC filings document material-event disclosures for an Ireland-incorporated specialty materials issuer, including operating results, earnings-release exhibits, investor presentations, capital-structure discussions, credit-facility waivers and listing-status records. Recent Form 8-K reports address financial results and stakeholder discussions involving debt and waiver arrangements, while Form 25 records the removal of the company’s ordinary shares from NYSE listing and the transition of trading to the OTC symbol TSEOF.
Trinseo PLC outlines a series of credit agreement amendments and temporary waivers after missing certain interest and principal payments beyond contractual grace periods. Lenders under its super-priority revolving credit facility removed anti-cash hoarding provisions and a minimum liquidity covenant, and agreed to a limited waiver of acceleration and collateral enforcement rights until April 30, 2026, in exchange for an in‑kind consent fee of 1.00% of each lender’s commitments.
Similar limited waivers under the Senior Credit Agreement and the Refinance Credit Agreement also run through April 30, 2026, with an additional 1.00% in‑kind consent fee on each participating lender’s outstanding loans under the refinance facility. A separate securitization waiver under the accounts receivable facility extends only until April 2, 2026. The company continues discussions with financial stakeholders on restructuring its capital structure, while noting that the New York Stock Exchange has begun delisting proceedings for its ordinary shares.
Trinseo PLC reports that several subsidiaries have entered into amendments and limited waivers with lenders under its super-priority revolver, senior and refinance credit agreements, and accounts receivable securitization facility. These waivers temporarily restrict lenders from accelerating debt or enforcing collateral remedies into late April 2026.
On March 19, 2026, Trinseo-related entities elected not to make scheduled interest payments of approximately $10 million under the 2L Notes Indenture and approximately $12 million under the Senior Credit Agreement after contractual grace periods lapsed. These non-payments are events of default and trigger cross-defaults across multiple facilities, though no accelerations have yet been declared. The filing also notes that the New York Stock Exchange has commenced proceedings to delist Trinseo’s ordinary shares, underscoring the company’s heightened financial stress as it continues capital structure negotiations.
Trinseo PLC reported weaker results for the fourth quarter and full year 2025. Fourth quarter net sales were $663 million, down 19% from 2024, with a net loss of $251 million versus $118 million a year earlier. The quarter included $127 million of pre-tax restructuring and other charges, while Adjusted EBITDA held roughly flat at $26 million.
For 2025, net sales were $2,974.9 million, down about 15%, and the full-year net loss widened to $545.6 million from $348.5 million. Full-year Adjusted EBITDA declined to $162.5 million from $203.7 million. Free Cash Flow was negative $153.4 million, reflecting cash used in operations of $102.4 million and capital expenditures of $51.0 million.
At December 31, 2025, Trinseo had cash and cash equivalents of $146.7 million and long-term debt of $2,332.5 million. Shareholders’ equity was a deficit of $1,097.8 million, deeper than the prior year’s deficit. Management highlighted ongoing restructuring actions, cost savings efforts and investment in strategic growth areas, while noting multiple risks including high indebtedness and going concern uncertainties in its risk discussion.
Trinseo PLC’s annual report describes a specialty materials company under severe financial and listing pressure. Management discloses “substantial doubt” about Trinseo’s ability to continue as a going concern due to a heavy debt load, covenant uncertainty, looming maturities and challenging demand, inflation and geopolitical conditions.
The company is pursuing debt restructuring options, has used grace periods for interest on its 2028 Term Loan B and 2029 Refinance Senior Notes, and warns that failure to secure waivers or amend terms could trigger cross‑defaults and accelerations. On March 2, 2026, Trinseo received notice that the NYSE will delist its ordinary shares after the stock fell below the $15 million average market capitalization standard, and trading has been suspended.
