Huntsman Corporation and Olin Corporation have agreed to a merger of equals, which Huntsman’s leadership describes as beneficial across a range of market scenarios. Management outlines an estimated $300 million in identified annual synergies, split into roughly $75 million from combined purchasing and logistics, $75 million from epoxy business overlap and related integration, and $150 million from SG&A efficiencies, such as consolidating leadership, boards, audits and related costs.
In addition, Huntsman highlights more than $100 million of further value from replacing an existing chlorine supply contract with internal supply once that contract, which in the Americas runs through the end of 2030, expires. Management notes that these synergy estimates exclude potential commercial upside from a more competitive cost base and broader product offering, and links the total synergy and integration impact to EBITDA value comparable to either company on a standalone basis. A registration statement on Form S-4 for the share issuance is effective, and a joint proxy statement/prospectus has been mailed to Olin shareholders and Huntsman stockholders for approval of transaction-related proposals.
