OlinHuntsman is expected to serve end markets including automotive, construction and infrastructure, and industrial applications. Olin’s chemical products include chlorine and caustic soda, vinyls, epoxies, chlorinated organics, bleach, hydrogen and hydrochloric acid. Huntsman manufactures and markets diversified chemical products sold to manufacturers across consumer and industrial end markets.

Following the close of the transaction, current Olin President and CEO Ken Lane will serve as CEO of OlinHuntsman. Current Huntsman Chairman, President and CEO Peter Huntsman will serve as nonexecutive chairman of the combined company’s board of directors. Current Huntsman Executive Vice President and Chief Financial Officer Phil Lister will serve as CFO of the combined company.

The board of directors of OlinHuntsman will consist of 10 members, with equal representation from Olin and Huntsman. Todd Slater, current senior vice president and chief financial officer of Olin, will serve as chief integration officer of OlinHuntsman, reporting to the CEO. A strategic integration committee of the board will oversee integration and synergy realization.

Under the terms of the agreement, Huntsman shareholders will receive 0.5476 shares in Olin for each Huntsman share. Upon completion of the transaction, Olin shareholders will own approximately 54.5% of the combined company and Huntsman shareholders will own approximately 45.5%.

The transaction has been unanimously approved by the boards of directors of both companies. It is expected to close in the first half of 2027, subject to customary closing conditions, including required regulatory approvals and approval by Olin and Huntsman shareholders.

Upon closing, OlinHuntsman will be headquartered in The Woodlands, Texas.
