A sign for pharmaceutical company Pfizer Incorporated headquarters is displayed on 42 Street in New York October 20, 2009. US pharmaceutical giant Pfizer January 28, 2014 reported a big drop in quarterly profits, but bested analyst expectations and pointed to several new drugs in development. Pfizer, which has been bruised in recent quarters by patent expirations on some blockbuster drugs, said fourth-quarter profits fell nearly 60 percent due mainly to an asset sale in the year-ago period. However, fourth-quarter operating income in 2013 rose compared with the year-ago period.
