LONDON—European Union antitrust enforcers slapped Intel on Friday with a fresh $400 million fine in a long-running legal fight that the chipmaker appeared to have won last year.
The European Commission imposed the 376.4 million-euro fine after a court threw out an original 1.06 billion-euro penalty issued in 2009 over allegations that the Santa Clara, California-based company used illegal sales tactics to shut out smaller rival AMD.
