This Form 10-K covers the fiscal year ended December 31, 2025. Olin Corporation is a leading vertically integrated global manufacturer of chemical products and a leading U.S. manufacturer of ammunition. Operations are divided into three segments: Chlor Alkali Products and Vinyls (54% of sales), Epoxy (20% of sales), and Winchester (26% of sales). The company operates globally, with approximately 32% of 2025 sales generated outside the U.S.

Key Financial Metrics

Material Changes vs. Prior Period

• Profitability Decline: The company reported a net loss of $100.5 million in 2025, a reversal from a net income of $108.6 million in 2024. This was driven by lower operating results across all segments.
• Segment Performance:
  • Chlor Alkali: Segment income dropped to $181.1 million from $296.4 million. This included a $75.0 million pretax charge related to a litigation loss contingency (Shintech VCM dispute) and lower pricing, partially offset by higher volumes and a $34.5 million benefit from the 45V Clean Hydrogen Tax Credit.
  • Epoxy: Segment loss widened to $(103.5) million from $(85.0) million due to higher operating costs and lower pricing, despite volume increases.
  • Winchester: Segment income fell to $67.7 million from $237.9 million, primarily due to decreased commercial ammunition sales volumes and pricing, offset by higher military project revenue.
• Acquisitions: Acquired AMMO, Inc.'s small caliber ammunition assets for $55.8 million in April 2025.
• Joint Ventures: Announced the termination of the Blue Water Alliance (BWA) joint venture with Mitsui by end of 2025. Hidrogenii, LLC (hydrogen JV with Plug Power) commenced operations in Q2 2025.

Guidance, Outlook, and Risks

• 2026 Outlook: Management expects Q1 2026 operating results to be higher than Q4 2025, excluding the one-time litigation charge. However, results will be negatively impacted by higher planned maintenance turnaround costs and raw material costs. Capital spending is expected to be approximately $200 million.
• Litigation Contingency: Following a February 2026 jury verdict, Olin expects to pay approximately $185 million to Shintech in the first half of 2026. A $75.0 million charge was recorded in Q4 2025.
• Debt Covenants: On February 19, 2026, Olin amended its Senior Secured Credit Facility to modify financial covenants to be less restrictive and incorporated guarantees/collateral from domestic subsidiaries. This amendment was necessary to provide flexibility given recent operating results.
• Key Risks:
  • Cyclical Pricing: Exposure to volatile pricing in chemical and ammunition markets.
  • Regulatory: EPA regulations under TSCA regarding asbestos and chlorinated organics could increase costs or force capacity closures.
  • Environmental: Ongoing remediation costs estimated at $25–$35 million annually.
  • Government Contracts: Winchester relies on U.S. military contracts which are subject to termination for convenience.

Investor Verification Checklist

• Shintech Litigation Payment: Verify the timing and impact of the expected $185 million cash outflow in H1 2026.
• Credit Facility Amendment: Review the specific terms of the February 2026 credit facility amendment and the duration of the covenant relief period (expires Sept 30, 2027).
• 45V Tax Credit Realization: Confirm the ongoing qualification and annual benefit ($15–$20 million expected) from the clean hydrogen production tax credit.
• Winchester Commercial Demand: Monitor trends in commercial ammunition sales volumes and pricing, which significantly impacted 2025 results.
• Environmental Liabilities: Assess the $156.3 million environmental reserve and the potential for additional contingent liabilities estimated at $100 million.
