OLIN Corp

We anticipate the fourth quarter market environment, typically the weakest seasonal quarter for our businesses, to be more difficult than usual. We expect our Chemicals businesses’ fourth quarter 2026 results to be lower than third quarter 2026, as a result of elevated year-end customer destocking, higher feedstock costs, continued pressure from subsidized Asian exports, and significant planned maintenance turnarounds. We expect our Winchester business fourth quarter results to decline from third quarter 2026 levels as a result of normal seasonality and higher commodity metal costs. Overall, we expect Olin’s fourth quarter 2026 operating results to be lower than our third quarter 2026 levels.

Other corporate and unallocated costs in 2026 are expected to be higher than the $85.7 million in 2025.

In 2026, we expect to incur approximately $35 million to $40 million in acquisition-related costs associated with our anticipated merger with Huntsman.

During 2026, we anticipate environmental expenses in the $25 million to $30 million range, compared to $24.5 million in 2025.

We expect non-operating pension income in 2026 to be lower than the $20.6 million in 2025. Based on our plan assumptions and estimates, we do not expect to make any cash contributions to our domestic qualified defined benefit pension plan in 2026. We have several international qualified defined benefit pension plans for which we anticipate cash contributions of less than $5 million in 2026.

During 2026, we paid approximately $114 million to Shintech associated with the litigation matter discussed within Note 18 “Commitments and Contingencies,” of the notes to condensed financial statements, and previously recorded accruals for a VCM pricing dispute with Shintech. The Company does not currently expect to make additional material payments related to the matter during 2026.

In 2026, we currently expect our capital spending to be approximately $200 million. We expect 2026 depreciation and amortization expense to be approximately $470 million.

We currently believe the 2026 effective tax rate will be in the 15% to 25% range and we expect cash taxes to be a net payment of approximately $10 million.
