Sapient shareholders have been given an extension to accept Publicis Groupe's $3.7bn buyout for the fourth time. The deadline, which was previously Thursday 22 January, has been changed to 5 February 2015. Previous delays in closing the deal have been blamed on the additional time needed to deal with U.S. regulatory requirements, with a Publicis statement claiming additional time is needed "for the satisfaction of the CFIUS Condition and the FOCI Mitigation Plan Condition."
