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.

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.
