Huntsman Corporation and Olin Corporation have agreed to a blockbuster “merger of equals” that will reshape North America’s chemicals landscape, combining two major industrial players into a single $12+ billion company set to be named OlinHuntsman.
Announced June 16, 2026, the all-stock deal is expected to deliver more than $400 million in cost synergies and integration benefits, while creating a vertically integrated chemical giant spanning upstream feedstocks to advanced downstream materials.
The combined company will be led by Olin CEO Ken Lane, with Huntsman Chairman Peter Huntsman serving as non-executive Chairman of the Board. Leadership said the deal is designed to sharpen competitiveness across volatile global cycles and strengthen margins through scale and integration.
“This combination provides a compelling opportunity for Olin and Huntsman to create a more resilient and value-focused chemicals company anchored in North America,” said Ken Lane, President and Chief Executive Officer of Olin.
“Huntsman has built an impressive portfolio of polyurethane systems, formulation technologies and advanced materials serving technical, application-driven end markets. By integrating those capabilities with Olin's world-scale chemicals assets and operations and identified synergies and benefits, we will create an industry leader with greater flexibility to serve customers across the value chain, generate stronger cash flow across the cycle and pursue opportunities that neither business could fully capture on its own."
Peter Huntsman framed the merger as a response to intensifying global competition and supply chain realignment.
“As our industry continues to globalize, we compete more today against countries, than companies, trade policies and global supply chains than ever before,” said Peter Huntsman, Chairman, President and Chief Executive Officer of Huntsman.
“The opportunities this merger creates enable us to generate greater value for our shareholders, deliver exceptional service and products for our customers and provide greater stability and opportunities for our associates. This merger of equals takes two great companies and creates a much stronger global leader.”
Under the terms of the agreement, Huntsman shareholders will receive 0.5476 shares of Olin for each share of Huntsman, with ownership of the combined firm expected to split roughly 54.5% Olin and 45.5% Huntsman.
Beyond scale, executives are betting on deep operational integration—combining Olin’s chlorine, caustic soda, and other upstream chemical production with Huntsman’s downstream formulations and advanced materials business.
The companies say this will unlock more efficient conversion of feedstocks into higher-value products and strengthen cash flow through the cycle.
Peter Huntsman further stated, "Ken and I agreed to use an at-the-market exchange ratio using volume-weighted average prices over the trailing 30 days, measured as of the close of June 12, 2026. This delivers a premium to Huntsman's shareholders relative to the historical averages while reflecting current market conditions.
"It is also equitable for Olin's shareholders, smoothing out share price movements from last week's trading. Looking ahead, our shared focus is on capturing the significant long-term value this transaction creates for both sets of shareholders."
The merger has been unanimously approved by both boards and is expected to close in the first half of 2027, pending regulatory and shareholder approvals. The combined company will be headquartered in The Woodlands, Texas, and will continue to operate Olin’s Winchester ammunition business as part of its diversified industrial portfolio.
