The plummeting value of raw materials took its toll on the Berwyn-based manufacturer of plastic, latex and rubber, according to recently released fourth quarter and year-end financial results, but Trinseo aims to bounce back this quarter and year with stronger sales and better margins, the Herald Online reported.

An overall fourth quarter adjusted net loss of $23 million would have been a profit of $37 million had it not been for the hit on raw material values. Trinseo’s adjusted earnings before interest, taxes, depreciation and amortization “excluding inventory revaluation increased $23 million versus the prior year due to higher styrene monomer margins and higher equity affiliate income,” the article noted.

The company went public in June of last year and just wrapped up a split into two business divisions this January.

“I am proud of what we achieved during the year,” President and CEO Chris Pappas said in the article. “… We expect very strong results in the first quarter, excluding inventory revaluation, driven by customer restocking and higher margins on lower costs. For full-year 2015, we expect healthy year-over-year EBITDA improvement driven by cyclical rebound of styrene monomer, structural and cyclical improvement in polycarbonate, and volume growth in synthetic rubber and performance plastics, which will more than offset headwinds from the weaker euro.”
