Cerus Corporation (CERS, Financial) is a leading provider of medical equipment to the blood banking industry. Its equipment performs pathogen inactivation (PI) on donated blood, preventing infections via transfused blood caused by viruses and bacteria in donated units. Cerus gained significantly in the fourth quarter as it started to gain contracts with a significant number of U.S. blood centers for PI in platelets and plasma. We believe that Cerus has what is likely to be an insurmountable lead in the U.S., and market leading E.U. position for its products. We should see substantial growth for years to come as we expect these markets, which are currently worth about $800 million (for platelets and plasma), could grow to over $3 billion when PI is extended to red blood cell inactivation over the next three to four years.
