Chemical Industry Merger
Olin and Huntsman Merge to Form Chemical Giant in $2.43 Billion Deal
Key Points
The companies’ governance plan would place a combined board of 10 directors “split evenly between Olin and Huntsman designees plus the two CEOs,” with Lane to become CEO and Peter Huntsman to serve as non-executive chair.
The merger is supported by a voting/support agreement under which “Peter Huntsman and affiliated entities have committed their shares in favor of the transaction and against competing takeover proposals,” and the deal agreement includes detailed provisions “on the treatment of Huntsman and Olin equity awards.”
In the SEC filing, Olin described the merger structure as an “merger of equals” implemented via either (a) a direct merger (Huntsman merges into Olin with Olin as surviving entity) or (b) a two-step subsidiary arrangement using Olin’s merger subsidiaries “Olympus Merger Sub, Inc.” and “Hook Merger Sub LLC.”
Olin told employees in a Rule 425 email that “Winchester will continue to operate as an important business within the combined company,” and emphasized the deal as creating a “vertically integrated platform” with a “structurally lower cost position,” while warning that “today is only Day 1 of a long process.”
Olin Corporation and Huntsman Corporation announced a $2.43 billion all-stock merger on June 15, 2026, creating a new chemical giant called OlinHuntsman Corporation PR Newswire.

Together, the two companies generated roughly $12.5 billion in revenue in 2025 Pulse2. They project more than $400 million in cost savings, with $300 million expected within the first two years Modern Distribution Management.
How the Stock Deal Splits Ownership Between the Two Companies

Kenneth Lane to Lead Combined Firm, Peter Huntsman Steps Back

The new board will have 10 directors — five from each company, including both CEOs SEC Form 425. Olin's current CFO, Todd Slater, will become Chief Integration Officer, leading the team tasked with capturing the $400 million in promised savings Modern Distribution Management. The deal includes a $121 million break-up fee if either side walks away The Telegraph.
Vertical Integration Strategy Targets Raw-Material Cost Advantage
The core logic behind the deal is vertical integration. Olin makes chlorine and caustic soda — the raw materials used to produce epoxies and polyurethanes. Huntsman turns those materials into finished specialty chemicals Plastics Today. Combining them cuts out middlemen and locks in supply at lower cost.
Lane called it a "structurally lower cost position" and a chance to build a "resilient and value-focused chemicals company" StreetInsider. At least $100 million of the projected synergies come specifically from raw materials and logistics Modern Distribution Management. The new headquarters will be in The Woodlands, Texas, which is currently Huntsman's home base.
Winchester Stays Put, Antitrust Scrutiny Looms Ahead
Olin told employees in a formal communication filed with the SEC that "Winchester will continue to operate as an important business within the combined company" SEC Form 425. That puts to rest any speculation about a spin-off of Olin's ammunition division.

Antitrust watchers expect scrutiny in the North American chlorine and epoxy markets, where Olin already holds a dominant share ICIS. Analysts from UBS, Deutsche Bank, and JPMorgan pressed management on the deal's structure during a June 16 investor call, questioning the "merger of equals" framing given Olin's larger ownership stake Seeking Alpha.
