Pomerantz LLP said it is investigating claims on behalf of investors in Olin Corporation following a sharp share-price decline after the company reported second-quarter 2026 results. Olin said its financial performance was affected by an unplanned shutdown of its vinyl chloride monomer plant in Freeport, Texas, adding that the disruption cut second-quarter adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization) by $40 million and was expected to have a further $20 million impact in the third quarter as full rates were planned to resume late in the quarter. Olin shares fell $3.66, or 16.51%, to close at $18.51 on July 31, 2026. The investigation is examining whether Olin and certain officers and directors engaged in securities fraud or other unlawful business practices.
