Facebook could face a multimillion-euro fine for allegedly misleading European Union merger watchdogs when it won approval to buy the WhatsApp messaging service in 2014.
The EU's antitrust authority said Tuesday it suspects Facebook supplied "incorrect or misleading information" on linking data with WhatsApp when regulators cleared the tie-up two years ago. Officials said approval for the US$22 billion ($31.7b) deal isn't under threat.
Facebook is the latest US technology giant in the EU's sights this year after it ordered Apple to repay about €13b ($19.51b) in back taxes and stepped up three separate antitrust investigations into Google's behaviour.
Facebook said it was "confident that a full review of the facts will confirm Facebook has acted in good faith". "We've consistently provided accurate information about our technical capabilities and plans, including in submissions about the WhatsApp acquisition and in voluntary briefings before WhatsApp's privacy policy update."
EU Competition Commissioner Margrethe Vestager said earlier this year that officials were quizzing Facebook over privacy policy changes announced in August that would allow the advertising platforms on Facebook and Instagram to draw on data from WhatsApp.
