Trinseo PLC reported a challenging first quarter of 2026 marked by deep losses, heavy cash burn, and serious balance sheet stress. Net sales were $724.7 million, down from $784.8 million a year earlier, and the Company recorded a net loss of $115.9 million, or $3.20 per share, versus a $79.0 million loss.
Operating activities used $232.9 million of cash, and liquidity stood at $114.2 million as of March 31, 2026. Trinseo ended the quarter with $2.77 billion of debt and an accumulated deficit of $1,455.2 million, resulting in a shareholders’ deficit of $1,222.9 million.
The Company elected not to make certain interest payments, causing events of default that accelerated its major debt facilities and led to reclassification of essentially all borrowings as current. Management concluded that substantial doubt about Trinseo’s ability to continue as a going concern exists within one year, even as it pursues restructuring of its capital structure and obtained temporary waivers and amendments.
Trinseo remains active in multi‑year restructuring programs focused on plant closures and cost reductions, with additional charges expected. Separately, its ordinary shares were delisted from the NYSE effective March 30, 2026 and now trade over the counter under the symbol TSEOF.
