British American Tobacco’s Nigerian units have been fined $110 million (R2 billion) by the nation’s antitrust agency, which found that the Lucky Strike maker violated competition laws.

The Federal Competition & Consumer Protection Commission levied the fine after a three-year probe into practices at the cigarette maker, the agency said in a post on X. The tobacco company was found to have penalized retailers that gave equal prominence in stores to rival brands.

BAT agreed to pay the fine and will allow the commission to monitor its activities for two years to “ensure appropriate behavioral and business practices modification,” according to the statement.
