Trinseo PLC remained in Chapter 11 while reporting third-quarter 2026 net sales of $778.7 million and a net loss of $49.1 million, compared with net sales of $743.2 million and a net loss of $109.7 million a year earlier. The company filed its Chapter 11 cases on May 26, 2026 to restructure its capital structure. The proposed plan had not become effective and remained subject to court confirmation and closing conditions. Plan terms expect existing equity interests to be cancelled with no recovery. Non-binding mediation ended October 28, 2026 without an agreement.
For the nine months ended September 30, 2026, operating activities used $322.3 million of cash, versus $125.0 million in the prior-year period.

Trinseo PLC (TSEOQ) reported third-quarter 2026 net sales of $778.7 million, up 5% year over year, and a net loss of $49.1 million, versus $109.7 million. Adjusted EBITDA was $51.0 million, compared with $30.4 million. The company linked higher sales to pricing that passed through higher raw-material costs and commercial initiatives; lower volumes in Polymer Solutions and Engineered Materials reflected weak end-market demand and customer purchases pulled into the second quarter.
Quarterly operating cash flow was $25.9 million and free cash flow was $14.6 million, versus a $38.1 million use a year earlier; approximately $50 million of professional fees tied to the debt restructuring process affected free cash flow. For the first nine months of 2026, operating activities used $322.3 million, compared with $125.0 million. The quarter included $43.2 million in reorganization items and $56 million of lower interest expense resulting from the automatic stay associated with debt restructuring proceedings. At September 30, 2026, liabilities subject to compromise were $2,559.2 million. The company said ordinary-course operations were supported by court-approved all-trade motions and liquidity remained consistent with the second quarter.

Trinseo PLC is convening its 2026 annual general meeting on September 23, 2026 at 8:30 a.m. EST in Wayne, Pennsylvania, with a simultaneous audio and video link in Dublin, Ireland. Shareholders of record on July 30, 2026, holding a total of 36,559,868 ordinary shares, may vote in person or by proxy via Internet, telephone or mail.
Shareholders are asked to elect eleven directors for one-year terms, approve on an advisory basis the compensation of named executive officers, and approve the appointment of PricewaterhouseCoopers as independent registered public accounting firm while authorizing the audit committee to set auditors’ remuneration. The board, led by independent chair K’Lynne Johnson, reports that 10 of 11 nominees are independent and operates four standing committees, including an environmental, health, safety, sustainability and public policy committee. Executive pay is heavily performance-based, emphasizing Adjusted EBITDA, Free Cash Flow and safety metrics in the annual cash incentive plan, plus long-term equity, supported by strict share ownership guidelines, a clawback policy, double-trigger change-in-control protection and prohibitions on hedging and pledging.
Trinseo PLC, now a debtor-in-possession, reported second-quarter 2026 net sales of $845.4 million, up modestly from $784.3 million, but generated operating income of only $0.1 million. After $72.4 million of interest expense and $41.3 million of reorganization items, net loss was $119.6 million or $3.27 per share. For the first six months, net loss reached $235.5 million and operating cash use was $348.2 million.
As of June 30, 2026, Trinseo had total assets of $2,498.6 million, liquidity of $186.7 million (including $181.4 million of cash), and a shareholders’ deficit of $1,347.2 million. Prepetition obligations of $2,562.3 million are classified as liabilities subject to compromise under ASC 852, while new debtor-in-possession facilities totaled $279.9 million (OpCo DIP), $163.3 million (Super HoldCo DIP) and a $144.7 million 2026 AR Facility.
Under a Restructuring Support Agreement and joint prepackaged Plan, substantially all prepetition funded indebtedness is expected to be cancelled, discharged and released, general unsecured trade and similar claims are expected to be unimpaired and paid in full, and existing equity interests are expected to be cancelled with no recovery. Management concludes that substantial doubt about Trinseo’s ability to continue as a going concern exists within one year, given continued losses, cash outflows and significant 2028 debt maturities absent consummation of the restructuring. The company’s ordinary shares were delisted from the NYSE in March 2026 and trade over-the-counter.
