BAT Industries, the giant tobacco and financial services group, saw about GBP1 billion (about HK$11.9 billion) wiped off its London market value yesterday after a Florida court awarded US$750,000 in damages to a cancer sufferer.
The company sells the popular State Express 555 brand, the leading foreign brand in China. Its shares dropped almost 9 per cent to close 45 pence, or 8.8 per cent, down to GBP4.64.
BAT's American depositary receipts on the American Stock Exchange fell slightly at last week's close.
On Friday, a United States court found in favour of a plaintiff who had sued BAT's US subsidiary Brown and Williamson Tobacco, the third biggest US tobacco manufacturer, claiming it had not warned smokers tobacco could be dangerous.
Yesterday, analysts said investor confidence in the company had been shaken by the court decision, warning it could spur a string of cases against tobacco companies.
BAT said it would appeal against the decision.
Analysts also cautioned that BAT stock went ex-dividend yesterday, and the shares would have moved in response to a 10 p net dividend awarded at the group's interim last month.
