CEO Commentary
“These plans are a by-product of the continuing challenges we and our peers in the European chemical industry have been facing for the past several years, including weak end market demand, high energy prices, and increased imports from Asia. These decisions are never easy. With each one we know the livelihoods of colleagues and their families are being impacted. As we have done in each restructuring during this unprecedented trough, our primary focus has been on the safety of our colleagues, along with a respectful transition that aligns with our philosophy of simply doing the right thing.” – Frank Bozich, President and CEO, Trinseo
The Q4 2025 press release issued March 13, 2026 described a continued strategic focus on specialty materials transformation, recycled content growth, and restructuring cost savings, while Trinseo simultaneously engaged financial stakeholders to address capital structure concerns.
CFO Commentary
“The only changes based on the last time we talked, which is admittedly higher than it was last year, is in working capital. Predicting working capital is the $40 million outflow of working capital is a function of really two things: volume over the course of the year, which as Frank said, we are not baking into our forecast anything of significance there, but also raw material price.”– David Stasse, EVP and CFO, Trinseo (Q4 2024 Earnings Call, forward-looking on 2025)
For the Q4 2025 period, CFO David Stasse’s comments through the press release highlighted that cash provided by Q4 operations was $23 million, capital expenditures were $16 million, resulting in free cash flow of $7 million, and the company maintained combined liquidity (cash plus committed facility availability) of $334 million at year-end.

How the Market Reacted?
Trinseo’s stock had already been under extreme pressure well before the Q4 2025 earnings announcement on March 13, 2026. On March 2, 2026, the NYSE formally notified Trinseo that it would commence delisting proceedings after the company’s 30-trading-day average market capitalization fell below the minimum $15 million threshold, and trading in TSE shares was immediately suspended. S&P Global Ratings downgraded Trinseo to Selective Default (SD) on March 3, 2026, following missed interest payments on its 2028 Term Loan B and 2029 senior secured notes, with the secured debt further downgraded to D.
The Q4 2025 earnings release therefore landed against a backdrop of suspended trading, with shares potentially moving to the OTC Pink Limited Market rather than NYSE, and investors grappling with going concern language in the annual 10-K filing. The report’s flat Adjusted EBITDA at $26 million and modest free cash flow of $7 million for Q4 provided limited near-term reassurance given the scale of restructuring charges, $1.953 billion in total debt, and ongoing capital structure negotiations with financial stakeholders.
