Trinseo Posts $30 Million Q3 EBITDA, Sees Flat Finish to 2025

Trinseo (NYSE:TSE) reported third-quarter adjusted EBITDA of $30 million (earnings before interest, taxes, depreciation and amortization, excluding one-off items) and forecast a fourth-quarter result of $30 million to $40 million, as Asian imports, pricing pressure and an outage at its Americas Styrenics affiliate weighed on performance.

The specialty materials maker also guided to positive free cash flow of $20 million for the final quarter of 2025. Third-quarter free cash flow was negative $38 million, and available liquidity stood at $346 million at quarter-end, Executive Vice President and Chief Financial Officer David Stasse said. Trinseo expects year-end liquidity to exceed $350 million, helped by a seasonal release of working capital.

The Q4 forecast assumes market conditions seen during the year will persist, along with a somewhat more pronounced seasonal year-end slowdown and $5 million to $10 million of unfavorable raw material timing. In short: management sees the quarter roughly flat, not a rebound.

How did trade flows hit volumes and margins?

President and Chief Executive Officer Frank Bozich said imports of Asian polymers into the United States and Europe rose sharply beginning in the first quarter. He attributed the shift partly to customers building U.S. inventories ahead of anticipated tariffs and to Asian material being redirected toward Europe amid slowing Chinese demand.

The flows continued into the third quarter, contributing to volumes below year-ago levels — though similar to the second quarter. Bozich said it was too early to determine whether the changes were temporary or structural.

During the Q&A, he identified Taiwan and South Korea as the sources of the most problematic inflow increases for Trinseo's chemistries. Surplus capacity that previously supplied China, he said, is being redirected to Europe and North America.

There was a bright spot. Bozich said Trinseo saw higher sales rates for its more formulated, higher-margin products late in Q3 and into Q4, with formulated PMMA resins (acrylic-based polymers) up more than 10% year over year. The company is watching the trend but doesn't yet know whether it signals a broader market change.

What did the segments and the affiliate outage deliver?

Stasse said Q3 adjusted EBITDA included $9 million of unfavorable raw material timing and negative equity affiliate earnings from Americas Styrenics. The affiliate absorbed an $8 million third-quarter headwind tied to an unplanned June outage, which disrupted styrene production and forced it to buy higher-cost material. The total hit to equity income was $10 million — $2 million recognized in June, $8 million in Q3. Stasse said he did not believe capacity rationalization was necessary at the affiliate, despite lower global styrene margins.

Segment moves diverged:

• Engineered Materials: adjusted EBITDA flat year over year, as fixed-cost improvements and slightly higher PMMA resin volumes in construction and automotive offset lower medical sales, which a year earlier had benefited from stocking ahead of the Stade polycarbonate site's closure.
• Latex Binders: adjusted EBITDA fell $9 million, on lower European paper and board volumes plus pricing pressure in Europe and Asia. Battery binder sales volumes rose 27% year over year.
• Polymer Solutions: adjusted EBITDA declined $19 million, reflecting raw material timing, lower ABS volumes and an unfavorable mix after the polycarbonate plant closure.

What comes next for restructuring and 2026?

Bozich said Trinseo's decision to discontinue virgin MMA production in Italy and its intention to close a polycarbonate facility in Germany — the polystyrene site is what's slated for closure in Germany, pending works council negotiations — should improve EBITDA by $30 million next year. Cash savings from the projects should exceed restructuring costs beginning in 2026. The Rho, Italy, site will keep producing PMMA resin and host investments in recycled MMA.

Trinseo did not provide 2026 guidance. Bozich reiterated that a 10% volume increase across the portfolio would generate about $100 million of EBITDA, and said weaker-than-expected volumes and less-normalized Americas Styrenics earnings explain the shortfalls against expectations entering 2025 — while the company still delivered planned business wins, cost savings and the sale of its polycarbonate assets.

The bottom line: a flat quarter, a flat outlook, and management betting on restructuring rather than market recovery to move the number.
