Overview
- The companies announced the all-stock deal on Tuesday, June 16, 2026, using an exchange ratio of 0.5476 Olin shares for each Huntsman share that would leave Olin with about 54.5% of the combined firm and Huntsman with about 45.5%.
- Boards of both firms unanimously approved the transaction and named Olin CEO Ken Lane as CEO of OlinHuntsman with Peter Huntsman as non‑executive chair, Phil Lister as CFO, and Todd Slater as chief integration officer; they expect to close in the first half of 2027.
- Management projects roughly $12.5 billion in combined revenue, over $400 million in identified benefits including more than $300 million of near-term synergies from purchasing, operations and SG&A, an additional $100 million from raw‑material integration starting in 2031, and about $125 million in cash tax benefits.
- Investors reacted sharply against Huntsman stock with intraday drops reported up to about 18%, and the Monsey law firm Wohl & Fruchter LLP has launched a fairness investigation that cites an implied Huntsman price of about $13.85 per share based on Olin’s June 15 close.
- Next steps include customary regulatory filings and shareholder votes, with the deal exposing Huntsman holders to immediate market re‑pricing and potential litigation while the companies pursue integration that could reshape supply chains and margins in chlor‑alkali and polyurethane value chains.
