Key Highlights

  • HUN shares fell 5.66% to $14.99 in pre-market, down from a prior close of $15.89.
  • OLN shares surged 7.51% to $27.20 in pre-market, up from a prior close of $25.30.
  • The exchange ratio of 0.5476 Olin shares per HUN share implies a discount to Huntsman's Friday close.

Huntsman Corporation (NYSE:HUN) shares tumbled in pre-market trading after the company announced a merger of equals with Olin Corporation (NYSE: OLN) to create OlinHuntsman Corporation, a combined chemicals company with over $12.5 billion in 2025 revenue. The divergent pre-market moves reflect how the all-stock exchange ratio is being absorbed by investors in each company.

HUN stock dropped 5.66% to $14.99, opening the pre-market session at $15.91 before sliding sharply. Huntsman's prior close was $15.89, giving the stock a market capitalisation of approximately $2.79 billion. The 52-week range of $7.30 to $16.09 puts current pre-market levels near the top of the stock's recent trading history, with the selloff reflecting investor concern that the 0.5476 exchange ratio values Huntsman at a discount to prevailing market prices rather than offering a traditional acquisition premium.

Olin shares moved in the opposite direction, climbing 7.51% to $27.20 in pre-market after closing the prior session at $25.30. OLN had a market capitalisation of approximately $2.88 billion ahead of the announcement, with a 52-week range of $18.08 to $30.46. The pre-market gain reflects investor optimism around Olin's majority stake of approximately 54.5% in the combined entity and the structural benefits of integrating Huntsman's downstream polyurethane and advanced materials businesses with Olin's upstream chlorine and electrochemical unit assets.

Both stocks carry a Hold consensus from analyst communities covering the names. Olin's analyst breakdown shows a more constructive tilt, compared with Huntsman. OLN's consensus average price target of $27.33 sits just above its current pre-market level, while HUN's average sits at $12.85, below current trading levels.

The deal targets more than $400 million in identified cost synergies, with the majority expected within 24 months of closing. The transaction is expected to close in the first half of 2027, pending shareholder approvals from both companies and regulatory clearances.
