Huntsman Corporation describes progress on a proposed merger of equals with Olin Corporation. An Olin registration statement on Form S-4 for the issuance of Olin common stock in the transaction has been declared effective by the SEC, allowing both companies to proceed to special stockholder meetings on August 25, 2026 to vote on the proposals.
The joint proxy statement/prospectus was mailed on July 13, 2026 to shareholders entitled to vote. Huntsman highlights that the combination has not closed and remains subject to shareholder approvals, regulatory clearances and other conditions, and provides extensive forward-looking and risk disclosures about potential benefits, synergies and uncertainties.
Olin Corporation and Huntsman Corporation announced that the U.S. Securities and Exchange Commission declared effective Olin's Form S-4 registration statement for their previously announced all-stock merger of equals to form OlinHuntsman.
The companies describe the combined business as a leading North American chemicals company with assets in Europe and Asia, expected synergies, vertical integration and expanded chlorine optionality. Special meetings of Olin shareholders and Huntsman stockholders to vote on the transaction are scheduled for August 25, 2026, with holders of record as of July 9, 2026 entitled to vote. Completion is targeted for the first half of 2027, subject to customary conditions, including regulatory approvals and approval by both shareholder groups.
Huntsman Corporation and Olin Corporation report that the U.S. SEC declared effective Olin’s registration statement on Form S-4 for their previously announced all-stock merger of equals to form OlinHuntsman. The companies state the combination is expected to create a leading North American chemicals company with enhanced vertical integration and expanded chlorine optionality.
Special meetings for Olin shareholders and Huntsman stockholders to vote on the transaction are scheduled for August 25, 2026, with a record date of July 9, 2026. Completion of the merger is expected in the first half of 2027, subject to regulatory approvals and approval by both companies’ owners. Huntsman reports approximately $6 billion in 2025 revenues from continuing operations, with more than 55 facilities in about 25 countries.
Olin Corporation and Huntsman Corporation plan a stock-for-stock merger of equals, effected either by a direct merger of Huntsman into Olin or a two-step subsidiary merger. Each Huntsman share will convert into 0.5476 shares of Olin common stock, with cash paid instead of fractional shares.
Based on Olin’s July 9, 2026 closing price, this consideration equaled about $11.06 per Huntsman share. Olin shareholders vote on direct and subsidiary merger structures, related compensation and adjournment proposals; Huntsman stockholders vote on adopting the merger agreement, compensation and adjournment. The combination will proceed if Huntsman stockholders approve the merger proposal and Olin shareholders approve at least one merger structure.
Both boards unanimously support the transaction. Governance of the combined company will be shared, with Olin’s CEO Kenneth T. Lane as CEO and Huntsman’s CEO Peter R. Huntsman as non-executive chair, plus a balanced board and committees. If the subsidiary structure is used, Huntsman’s 2.950% 2031 and 4.500% 2029 notes will likely be refinanced at higher rates, increasing interest expense and reducing net income relative to the direct merger structure. Huntsman shares will be delisted, and the combined company will trade on NYSE under a new name and ticker.
Olin Corporation and Huntsman Corporation outline expected more than $400 million in annual cost synergies and integration benefits from their proposed combination. Management expects more than $300 million of annual near-term synergies, with over 90% anticipated within the first 24 months following closing, and more than $100 million of additional raw material integration benefits beginning in January 2031 after certain supplier contracts at Huntsman’s Geismar, Louisiana site expire.
The identified annual cost synergies comprise approximately $150 million SG&A savings from eliminating duplicative public‑company and corporate overhead, about $75 million from purchasing and raw material integration, and about $75 million from operational efficiencies and asset optimization. One‑time, non‑recurring costs to achieve the synergies are estimated at $150–$200 million. The companies also highlight an expected approximately $125 million one‑time cash tax benefit from accelerated use of net operating losses and note an estimated approximately $90 million economic benefit over five years from lower interest expense under the direct merger structure. Both companies emphasize vertical integration across chlorine, caustic soda, amines, MDI, epoxy and advanced materials as a key value driver and state that the newly formed OlinHuntsman would pursue additional revenue synergies not included in these figures.

Management highlights expected synergies including $75 million from purchasing and raw material integration and an additional $100 million of raw material integration benefits beginning in 2031. Integration planning, staffing impacts, benefits harmonization, and office footprint decisions will be evaluated after close; the companies say they intend to protect vested pension benefits and to communicate changes in advance.
