Two Merger Structures with Different Financial Impacts

Analysis · HUN · Industrial Applications And Services
This definitive proxy statement provides the first detailed look at the all-stock merger of equals between Huntsman and Olin, announced on June 16, 2026. The exchange ratio of 0.5476 Olin shares per Huntsman share implies a value of approximately $11.06 per Huntsman share based on Olin's July 9 closing price, a discount to Huntsman's pre-announcement trading levels. The filing outlines two alternative merger structures: a direct merger (preferred) that preserves Huntsman's low-interest bonds, and a subsidiary merger that would trigger a change-of-control offer on $1.15 billion of Huntsman notes, likely requiring higher-cost refinancing. The combined company, to be named OlinHuntsman Corporation, will have a 10-member board split evenly between the two companies, with Olin's CEO Kenneth Lane as CEO and Huntsman's CEO Peter Huntsman as non-executive chairman. The deal is expected to close in the first half of 2027, subject to shareholder and regulatory approvals. The proxy includes fairness opinions from Lazard (for Olin) and Citi and Morgan Stanley (for Huntsman), and projects over $300 million in near-term cost synergies. The vote is scheduled for August 25, 2026, with both companies' boards unanimously recommending approval.
