CLAYTON, Missouri and THE WOODLANDS, Texas, July 14, 2026 /PRNewswire/ -- Olin Corporation (NYSE: OLN) ("Olin") and Huntsman Corporation (NYSE: HUN) ("Huntsman") today announced that on July 13, 2026, the U.S. Securities and Exchange Commission declared effective the registration statement on Form S-4 (the "Registration Statement") filed by Olin in connection with the previously announced all-stock merger of equals (the "Transaction") to form a combined company, OlinHuntsman.

The combined company is expected to:

  • Realize more than $400 million of cost synergies and integration benefits, including (1) more than $300 million of annual cost synergies and integration benefits expected to be achieved by the end of year three, with more than 90% of that total expected within the first 24 months following the closing of the Transaction and (2) more than $100 million of additional raw material integration benefits beginning in 2031; 

  • Generate revenue synergies through vertical integration by combining complementary upstream and downstream capabilities, including Olin's manufacturing and feedstock capabilities with Huntsman's downstream products and formulation expertise, enabling OlinHuntsman to grow with customers at multiple points in the value chain, utilize lower-cost producer economics to drive value globally, and improve margins and cash flow through a more efficient operating model;

  • Capture value and margin across the full chemical value chain, from upstream inputs like electricity and salt through to downstream products serving aerospace, automotive, electronics, alternative energy, composites, construction and consumer markets;

  • Combine complementary portfolios with an enhanced geographic footprint across the U.S. Gulf Coast, Europe and Asia, enabling OlinHuntsman to capitalize on regional sector dynamics and better serve customers across key markets;
