Olin Corporation will record a $75 million pre-tax charge in Q4 2025 following an adverse verdict in the Shintech litigation regarding a contract dispute. The chemical manufacturer expects a $185 million total cash impact in early 2026.

In April 2023, Shintech filed a lawsuit seeking damages against Olin. The litigation involved a pricing dispute between Shintech and Olin, a 2023 maintenance turnaround of a vinyl chloride monomer (VCM) plant and a disputed force majeure event. Olin supplies VCM to Shintech under a long-term supply contract. Following three years of active litigation, the jury returned a verdict in favor of Shintech on February 10, 2026.

Olin was disappointed by the verdict and is currently assessing its legal rights and options. The Company firmly believes that its actions at the time were appropriate and aligned with best industry practices to prioritize the safety of its employees and the community.

As a result of this verdict, the company obtained new information related to this litigation loss contingency and recorded a one-time, pre-tax charge of $75 million in the fourth quarter 2025, which will be reflected in the December 31, 2025 consolidated financial statements included in the company's 2025 Form 10-K. Fourth quarter 2025 adjusted EBITDA will exclude this non-recurring charge. “We expect to pay approximately $185 million, including previously accrued reserves, during the first half of 2026 related to this matter,” the company said.
