Huntsman shareholders will receive 0.5476 Olin shares per share, resulting in Olin shareholders owning 54.5% and Huntsman shareholders 45.5% of the combined entity. The merger anticipates over $400 million in total cost synergies and integration benefits, with $300 million realized within 24 months and the remainder by year three, plus an additional $100 million from 2031.
