Major News! World's Leading Chlor-Alkali Giant Acquires Huntsman!

On June 16, Olin, the world's leading chlor-alkali supplier, and Huntsman, a leader in the polyurethane industry, announced a merger. The two parties aim to create a premier chemical enterprise with a market capitalization exceeding $12 billion.

Upon completion of the transaction, the merged entity will be renamed "Olin Huntsman Corporation."

The new company will integrate operations across chlor-alkali, epoxy resins, polyurethanes, amine chemicals, and advanced materials platforms, positioning itself as one of the few global chemical groups spanning the entire value chain from basic chemicals and specialty chemicals to end-use application solutions.

Huntsman: A Global Polyurethane Giant

Huntsman is an iconic player in the global polyurethane sector, specializing in MDI, polyurethane systems, and advanced materials. It operates over 55 manufacturing and R&D facilities across approximately 25 countries and employs around 6,000 people. In 2025, the company reported revenue of $5.683 billion (down 5.8% year-over-year) and a net loss attributable to shareholders of $284 million; however, free cash flow rose 23.8% to $125 million.

The polyurethane segment accounts for 65% of the company's revenue. An 11% drop in the average selling price of MDI dragged down full-year EBITDA by 40% year-over-year, with the figure nearly halving in the fourth quarter alone. On April 1, 2026, Huntsman China announced a 30% price hike for polyurethanes and downstream products in an attempt to offset upstream cost pressures. However, it remains to be seen whether the market will absorb these price increases.

Notably, Huntsman is deeply involved in the Chinese market. It built its first 160,000-ton MDI plant in Shanghai Caojing in 2006 (the first foreign-owned MDI production line in China) and commissioned a second phase with a 240,000-ton capacity in 2018; its current MDI capacity in China stands at 400,000 tons, representing nearly half of its global total. In early 2024, the Shanghai Lianheng joint-venture MDI plant underwent a restructuring, leading to independent operations for Huntsman and Shanghai Chlor-Alkali Chemical and ending a joint venture with BASF that had lasted over a decade. The company has invested over RMB 15 billion in China to date, with its Asia-Pacific headquarters for both polyurethanes and advanced materials located in Shanghai.

Olin: A Global Chlor-Alkali Giant

Olin is a leading global integrated manufacturer of chlor-alkali and vinyl products and also owns Winchester, the largest ammunition brand in the U.S. In 2024, the company reported revenue of $6.54 billion, net income of $109 million, and adjusted EBITDA of $815 million. Among its three business segments, Chlor-Alkali & Vinyls accounts for 56%, Epoxy for 19%, and Winchester Ammunition for 25%. Notably, the Epoxy segment has been consistently loss-making; Olin closed its solid epoxy resin plants in the Netherlands, South Korea, and Brazil in 2023, signaling a clear trend of contraction.

The core rationale behind this merger is vertical integration: Olin’s upstream raw materials—such as chlorine, caustic soda, and vinyl chloride—complement Huntsman’s downstream capabilities in MDI, polyurethane formulations, and advanced materials, transforming the entity from a "basic chemical producer" into a "full-chain supplier ranging from raw materials to end products." Post-merger, OlinHuntsman will possess the ability to convert low-cost electrochemical unit (ECU) capacity into high-value-added downstream materials, thereby securing a structural cost advantage.

Key Merger Data:
· Exchange Ratio: 0.5476 Olin shares for each Huntsman share
· Equity Split: Olin shareholders ~54.5%; Huntsman shareholders ~45.5%
· Synergies: $400 million+ ($300 million realized within 24 months; $100 million in raw material integration gains starting in 2031)
· Tax Benefits: Accelerated recognition of approximately $125 million in net operating losses
· Leadership: Ken Lane (Olin CEO) → CEO of the merged company; Peter Huntsman → Non-executive Chairman; Phil Lister (Huntsman CFO) → CFO
· Headquarters: The Woodlands, Texas (current Huntsman headquarters)

What does this mean for the polyurethane industry?

The merged Olin-Huntsman entity will become a formidable global force in the polyurethane sector, combining upstream self-sufficiency in chlor-alkali raw materials with comprehensive downstream MDI formulation capabilities; it is poised to form a competitive triad alongside Wanhua Chemical and Covestro. While the direct impact on the Chinese market may be limited, certain factors warrant attention:

Huntsman’s 400,000-tonne MDI plant in Caojing, Shanghai, is one of its three major global MDI production hubs and will likely continue operations post-merger (given that Peter Huntsman remains Chairman and the CFO hails from Huntsman, ensuring significant management influence). However, Olin-Huntsman’s strategic focus lies in North America—the merger announcement explicitly emphasizes being "anchored in North America," suggesting that future capital expenditure may skew toward the U.S. Gulf Coast.

China currently accounts for 45% of global MDI capacity, with Wanhua Chemical alone holding a 32% share; Huntsman already faces stiff competition in China, and it remains uncertain whether it will continue to ramp up investment there following the merger.

On another front, there is an overlap in applications (such as coatings and industrial adhesives) between Olin’s epoxy business and Huntsman’s advanced materials division. Post-merger integration could trigger a new round of capacity optimization—Olin has previously scaled back epoxy capacity in Europe and Asia, and further divestment of non-core assets cannot be ruled out.

Currently, Huntsman is in a phase of earnings recovery: it posted a net loss of $284 million for the full year of 2025, with average MDI prices falling 11% year-over-year and polyurethane EBITDA dropping 40%. "Stemming the bleeding before pursuing growth" is the first hurdle facing the merged company; the ability to realize synergies within two years will determine the fate of this merger of equals.
