With shares of Chemours (CC) down only 13c to $22.08 after a jury in Ohio ordered DuPont (DD) to pay $10.5M in punitive damages in the Vigneron case, Citi analyst P.J. Juvekar says investors could be underestimating the size of the company's potential liability. This is the third and largest verdict issued against DuPont for personal injuries linked to perfluorooctanoic acid exposure, Juvekar tells investors in a research note. He notes that a poll by firm found a majority of respondents expect the PFOA liability will be greater than $1B. He keeps a Neutral rating on shares of Chemours.
