A California jury has awarded $81 million to a man who claimed his cancer was caused by exposure to Bayer's (BAYRY) Roundup weed killer, marking another legal setback for the company, according to published reports.

The federal court jury awarded $5.9 million in compensatory damages and $75 million in punitive damages after it determined the company failed to warn the plaintiff of the widely-used herbicide's cancer risk and had acted negligently, Reuters reported.

Last week the jury found that Roundup was a substantial factor in causing the victim's cancer, setting the stage for the second trial to determine damages.

Bayer bought Roundup maker Monsanto last year in a $63 billion deal.

The company faces more than 10,000 lawsuits from people claiming Roundup caused their cancer.

Bayer is expected to report earnings of 65 cents a share on sales of $14.4 billion on Apr. 25, based on a FactSet survey of 5 analysts. In the same period a year ago the company posted earnings of 67 cents a share on sales of $10.9 billion. 

Bayer American depositary receipts fell 20 cents, or 1.25% to $15.82 during regular trading Wednesday.
