Olin (OLN) and Huntsman (HUN) on Tuesday said they agreed to merge in an all-stock deal to create a larger North American chemicals company with more than $12 billion in annual revenue.
Under the terms of the agreement, diversified chemical products maker Huntsman's shareholders will receive 0.5476 Olin shares for each share they own, the companies said in a joint statement.
The transaction is expected to close in the first half of 2027, subject to regulatory and shareholder approvals. Upon completion, the combined company will be renamed OlinHuntsman. Olin shareholders are expected to own about 54.5% of the combined company, while Huntsman shareholders will own the remaining 45.5%.
The combined company would have generated about $12.5 billion in 2025 revenue, the statement said. It is expected to serve a range of end markets including automotive, construction, infrastructure and industrial applications. OlinHuntsman will benefit from a lower cost position and a greater ability to convert its electrochemical unit production into downstream materials, creating new growth opportunities, according to the statement.
The deal will also combine Olin's manufacturing and feedstock capabilities with Huntsman's downstream products and formulation expertise, while Olin's Winchester ammunition business will continue operating within the company.
"This combination provides a compelling opportunity for Olin and Huntsman to create a more resilient and value-focused chemicals company anchored in North America," Olin chief executive Ken Lane said.
Olin and Huntsman expect the merger to generate more than $400 million in synergies and integration benefits.
Upon closing of the transaction, Lane will lead the combined company, while Huntsman CEO Peter Huntsman will serve as non-executive chairman of the board. OlinHuntsman will be headquartered in Texas.
Earlier this month, Huntsman said it sold its Italy-based automotive aftermarket components business Gomet to Trelleborg Group for about $50 million.
