Quarterly adjusted EBITDA of $67.7 million
Year-end 2025 net debt comparable to year-end 2024

CLAYTON, Mo., Jan. 29, 2026 /PRNewswire/ -- Olin Corporation (NYSE: OLN) announced financial results for the fourth quarter ended December 31, 2025. Fourth quarter 2025 reported net loss was ($85.7) million, or ($0.75) per diluted share, which compares to fourth quarter 2024 reported net income of $10.7 million, or $0.09 per diluted share. Fourth quarter 2025 adjusted EBITDA of $67.7 million excludes depreciation and amortization expense of $125.7 million and restructuring charges of $19.1 million. Fourth quarter 2024 adjusted EBITDA was $193.4 million. Sales in the fourth quarter 2025 were $1,665.1 million, compared to $1,671.3 million in the fourth quarter 2024. Full year 2025 reported net loss was ($42.8) million, or ($0.37) per diluted share, which compares to full year 2024 reported net income of $108.6 million, or $0.91 per diluted share.

Ken Lane, President and Chief Executive Officer, said, "During the fourth quarter, we experienced continued headwinds related to the trough market environment exacerbated by customer destocking as well as planned maintenance turnarounds and unplanned operating events. Despite that, we remain committed to executing our value-first commercial approach and are focused on our Optimize the Core strategic priorities: operating safely and reliably, delivering our Beyond250 structural cost reductions and maximizing cash generation. We have begun to see benefits from our Beyond250 initiative, realizing a $44 million reduction in structural costs in 2025. As a result of proactive actions taken, we generated $321.2 million of operating cash flow in fourth quarter 2025 and ended the year with net debt comparable to year-end 2024.

"Operational challenges and weaker than expected chlorine demand impacted our Chlor Alkali Products and Vinyls segment fourth quarter 2025 performance. Our Chlor Alkali Products and Vinyls business remains committed to maintaining our operating discipline and preserving our Electrochemical Unit (ECU) values in the current trough environment."

Lane continued, "Although global epoxy demand remains challenged, as one of the last integrated and lowest cost epoxy producers, we have grown our participation in the United States and European epoxy markets, despite continued market saturation from subsidized Asian competitors. We also continue to grow sales of our formulated solutions products. Given these results, in combination with the benefits from our new Stade, Germany supply agreement and our on-going Beyond250 initiative to reduce structural costs, including the recent decision to close our Guarujá, Brazil Epoxy production site, we anticipate our Epoxy business will return to profitability in 2026.

"Winchester's fourth quarter 2025 efforts to right-size inventories in the value chain have accelerated channel destocking. Winchester continues to experience rising raw material costs, including copper, brass, and propellant. To help mitigate these significant cost pressures, Winchester is implementing increased commercial ammunition pricing for the first quarter 2026. Our military business continues to deliver strong growth."

Commenting on Olin's outlook for first quarter 2026, Lane continued, "As a result of upcoming sequentially higher planned maintenance turnaround costs and higher raw material costs, including increased electrical power costs, we expect first quarter 2026 results from our Chemicals businesses to be lower than fourth quarter 2025. In our Winchester business, as commercial customer inventories become more normalized, we expect our first quarter 2026 results to modestly increase from fourth quarter 2025. Overall, we expect Olin's first quarter 2026 adjusted EBITDA to be lower than fourth quarter 2025 levels."

SEGMENT REPORTING

Olin defines segment earnings as income (loss) before interest expense, interest income, other operating income (expense), non-operating pension income, other income, and income taxes, and includes the results of non-consolidated affiliates in segment results consistent with management's monitoring of the operating segments.

CHLOR ALKALI PRODUCTS AND VINYLS

Chlor Alkali Products and Vinyls sales for the fourth quarter 2025 were $856.4 million, compared to $953.7 million in the fourth quarter 2024. The decrease in sales was primarily due to lower pricing, partially offset by higher volumes. Fourth quarter 2025 segment loss was ($14.7) million, compared to segment earnings of $75.2 million in the fourth quarter 2024. The $89.9 million decrease in segment earnings was primarily due to lower pricing and higher operating costs, primarily from unabsorbed fixed costs incurred from production disruptions and planned maintenance turnarounds, partially offset by higher volumes and decreased costs associated with products purchased from other parties. Chlor Alkali Products and Vinyls fourth quarter 2025 results included depreciation and amortization expense of $101.1 million compared to $105.5 million in the fourth quarter 2024.

EPOXY

Epoxy sales for the fourth quarter 2025 were $359.3 million, compared to $282.2 million in the fourth quarter 2024. The increase in sales was primarily due to higher volumes. Fourth quarter 2025 segment loss was ($19.2) million, compared to segment loss of ($27.4) million in the fourth quarter 2024. The $8.2 million increase in segment results was due to higher volumes and a favorable product mix, partially offset by higher operating costs, primarily from planned maintenance turnarounds. Product margins were comparable year over year. Epoxy fourth quarter 2025 results included depreciation and amortization expense of $12.6 million compared to $13.1 million in the fourth quarter 2024.

WINCHESTER

Winchester sales for the fourth quarter 2025 were $449.4 million, compared to $435.4 million in the fourth quarter 2024. Sales were comparable as higher military sales and military project revenue were offset by lower commercial ammunition sales. Fourth quarter 2025 segment earnings were $0.6 million, compared to $42.0 million in the fourth quarter 2024. The $41.4 million decrease in segment earnings was primarily due to lower commercial ammunition pricing and shipments and higher operating and raw material costs, including propellant and commodity metal costs. Winchester fourth quarter 2025 results included depreciation and amortization expense of $9.0 million compared to $9.1 million in the fourth quarter 2024.

CORPORATE AND OTHER COSTS

Other corporate and unallocated costs in the fourth quarter 2025 were $1.5 million lower than the fourth quarter 2024 as lower legal and legal-related settlement costs, were partially offset by higher incentive costs, including mark-to-market adjustments on stock-based compensation.

RESTRUCTURING CHARGES

Restructuring charges in the fourth quarter of 2025 included a charge of $9.6 million, including a $4.1 million non-cash asset impairment charge, for the planned closure of our epoxy resin manufacturing facility in Guarujá, Brazil in the first quarter 2026. Olin expects to realize structural cost savings of approximately $10 million annually, while continuing to serve our Brazilian epoxy customers.

LIQUIDITY AND SHARE REPURCHASES

The cash balance on December 31, 2025, was $167.6 million. Olin ended the fourth quarter 2025 with net debt of approximately $2.7 billion and a net debt to adjusted EBITDA ratio of 4.1 times. On December 31, 2025, Olin had available liquidity of approximately $1.0 billion.

During fourth quarter 2025, approximately 0.5 million shares of common stock were repurchased at a cost of $10.1 million. During 2025, approximately 2.2 million shares of common stock were repurchased at a cost of $50.5 million. On December 31, 2025, Olin had approximately $1.9 billion available under its share repurchase authorizations.

Non-GAAP Financial Measures - Adjusted EBITDA (a)
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 provision (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 the 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 provision (benefit), other expense (income) and restructuring charges (income). Because of our inability to calculate such adjustments, forward-looking net income guidance is also omitted from this release. We expect these adjustments to have a potentially significant impact on our future GAAP financial results.

Non-GAAP Financial Measures - Net Debt to Adjusted EBITDA (a)
Olin's definition of Net Debt to Adjusted EBITDA is Net Debt divided by Adjusted EBITDA. Net Debt at the end of any reporting period is defined as the sum of our current installments of long-term debt and long-term debt, less cash and cash equivalents. 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 provision (benefit), other expense (income), restructuring charges (income) and certain other non-recurring items. Net Debt to Adjusted EBITDA is a non-GAAP financial measure. Management believes that this measure is meaningful to investors as a measure of our ability to manage our indebtedness. The use of non-GAAP financial measures is not intended to replace any measures of indebtedness or liquidity determined in accordance with GAAP and Net Debt or Net Debt to Adjusted EBITDA presented may not be comparable to similarly titled measures of other companies.
