The fallout from Facebook's Cambridge Analytica scandal is hitting one data marketing firm hard. 

Acxiom, which uses Facebook data for better targeted marketing, lost a third of its value on Thursday after Facebook decided to end its "Partner Categories" program, which fed data to firms like Acxiom. The company's shares fell 31 percent to $19.45.
