Olin Corporation announced an updated outlook for the fourth quarter 2025. Olin now expects fourth quarter 2025 adjusted EBITDA to be approximately $67 million compared to the previous outlook of $110 to $130 million.

Most of the earnings shortfall occurred within the Chlor Alkali Products and Vinyls business, reflecting an extended planned maintenance turnaround and unplanned downtime at our Freeport, Texas operations, as well as lower-than-expected pipeline chlorine demand.

Ken Lane, President and Chief Executive Officer, said, "Late in the quarter, our Chlor Alkali Products and Vinyls was impacted by a meaningful decline in chlorine demand as well as operational issues at our Freeport, Texas site related to a planned turnaround and interruption of raw material supply by a third party. Our Freeport, Texas site has returned to normal operations. In spite of these challenges, the Olin Team remains focused on operating our assets safely, delivering on our cost reduction targets and maintaining our disciplined value-first commercial approach."
