CLAYTON, Mo., Jan. 8, 2026 /PRNewswire/ -- Olin Corporation (NYSE:OLN), today 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."

NON-GAAP FINANCIAL MEASURES

Olin's definition of Adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization) is net income (loss) plus an add-back for depreciation and amortization, interest expense (income), income tax expense (benefit), other expense (income), restructuring charges (income), and certain other non-recurring items. Adjusted EBITDA is a non-GAAP financial measure. Management believes that this measure is meaningful to investors as a supplemental financial measure to assess financial performance without regard to financing methods, capital structures, taxes, or historical cost basis. The use of non-GAAP financial measures is not intended to replace any measures of performance determined in accordance with GAAP and Adjusted EBITDA presented may not be comparable to similarly titled measures of other companies.

Reconciliation of forward-looking non-GAAP financial measures to the most directly comparable GAAP financial measures are omitted from this release because Olin is unable to provide such reconciliations without the use of unreasonable efforts. This inability results from the inherent difficulty in forecasting generally and quantifying certain projected amounts that are necessary for such reconciliations. In particular, sufficient information is not available to calculate certain adjustments required for such reconciliations, including interest expense (income), income tax expense (benefit), other expense (income) and restructuring charges (income).
