Here are the 10-Q quarterly reports from Trinseo PLC (TSEOQ) in our archive since June 2025, newest first, and each one links through to the document itself with the summary and the scores our analysis gives it.
A 10-Q covers the quarterly report filed between annual reports, so if you follow TSEOQ and want that one kind of document rather than the whole filing history, this is the page to keep. The company's other filings, of every form, are on the full TSEOQ filings page.
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. Available liquidity was $186.2 million as of September 30, while total debt was $3,020.9 million and liabilities subject to compromise were $2,559.2 million. Trinseo reported compliance with weekly liquidity covenants under both debtor-in-possession facilities.
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.
