KEY POINTS
  • Publicis Groupe announced Sunday a $4.4 billion buy of data marketing firm Epsilon as it makes a big play to better its offerings in the digital marketing space.
  • Some analysts expressed skepticism about the ad holding company's ability to painlessly integrate Epsilon, given the difficulty of its integration of Sapient a few years ago. 
  • Analysts believe Publicis' ownership of first-party data as part of this deal is a positive as ownership in data is becoming increasingly important.

Analysts are skeptical about Publicis Groupe's plans to buy data marketing firm Epsilon for $4.4 billion, noting past integration struggles and a questionable strategic fit.

Publicis Groupe, one of the world's largest ad holding companies, contains agencies including Starcom, Leo Burnett and Digitas. The advertising world is grappling with the huge growth of digital advertising and the emergence of Facebook and Google, which collect huge amounts of detailed data about users and use it to target ads. Publicis hopes this deal will help its clients make sense of the data they already have on their customers, and use it to better understand what customers might do next and see how well their ads are working.
