The scrutiny follows Olin’s July 30, 2026, second-quarter financial disclosure, which revealed that a breakdown at the vinyl chloride monomer facility in Freeport, Texas, severely hampered operations. Management estimated the disruption cut adjusted EBITDA by $40 million during the quarter, with an additional $20 million impact projected for the third quarter as the site works toward resuming full production.

Investors reacted sharply to the news, sending the stock price down $3.66 to close at $18.51 on July 31. Pomerantz LLP, a firm specializing in securities class litigation, is currently soliciting information from affected shareholders to determine if the company’s conduct warrants legal action.
