Bayer shares tumbled more than 12 percent on Wednesday after a unanimous jury in San Francisco federal court found Roundup to be a “substantial factor” in causing California resident Edwin Hardeman’s non-Hodgkin’s lymphoma. The jury decision was a blow to Bayer after the judge in the Hardeman case, at the company’s request, had split the trial, severely limiting evidence plaintiffs could present in the first phase. Tuesday’s defeat on terms considered advantageous to Bayer sets up the second phase to be even tougher and limits the grounds on which the company could appeal any final verdict, the experts said.
