Bayer shares plunged as much as 14 percent on Monday, losing about $14 billion in value, after newly acquired Monsanto was ordered to pay $289 million in damages in the first of possibly thousands of U.S. lawsuits over alleged links between a weedkiller and cancer.
After the verdict in favor of a California school groundskeeper with terminal cancer, Monsanto faces more than 5,000 similar lawsuits across the United States over claims it did not warn of the cancer risks of glyphosate-based weedkillers, including its Roundup brand.
Monsanto, bought by Bayer this year for $63 billion, said that it would appeal against the jury's verdict in California, which is the latest episode in a long-running debate over claims that exposure to Roundup can cause cancer.
