Grifols, the Spanish biotherapeutics company with a large presence in the Triangle, announced Monday that it is acquiring Novartis diagnostics business unit for $1.68 billion.
The acquisition includes a manufacturing plant in Emeryville, Calif. as well as offices in the U.S., Switzerland and Hong Kong.
Grifols employs several thousand people in the Triangle. In 2010, the company acquired Talecris, which is based in Research Triangle Park and has a drug-manufacturing facility in Clayton, for $3.4 billion.
Grifols and Talecris make medicine from blood plasma, used to treat a wide range of diseases, including hemophilia and various immune system deficiencies. Last year, Grifols invested $25 million expanding its Clayton facilities.
Grifols said it expects the acquisition of Novartis blood unit to increase annual revenue for its diagnostics division to nearly $1 billion. That division is expected to account for about 20 percent of the Barcelona-based companys sales.
The deal is expected to close in the first half of next year.
