Controlling shareholder Guan Yanbin sentenced to 11 years in first instance for intentional homicide
In July 2020, Sunflower Pharmaceutical Group announced that its controlling shareholder, Guan Yanbin, had been sentenced to 11 years in prison in the first instance for intentional homicide, a case arising from a conflict with his ex-wife. The incident prompted discussion of corporate governance and controlling-shareholder risk. The criminal liability rests with Guan Yanbin personally and does not support any finding that Sunflower's products have quality problems.
