An agreement worth $2.5 million to settle a class action securities fraud suit was reached last week between Norcross, Ga.-based Immucor, a medical supply company specializing in blood testing and transfusion products, and attorneys representing stock purchasers alleging the firm’s officers issued misleading information concerning its financial health in 2004 and 2005.

A suit filed Aug. 31, 2005, said the company misled investors as to the impact of a criminal investigation of its Italian subsidiary and that unit’s president, Dr. Gioacchino De Chirico, who has since been named Immucor’s president.
