Amazon's iRobot acquisition to face EU antitrust investigation

$Amazon(AMZN.US)$ $1.7B acquisition of $iRobot(IRBT.US)$ is set to undergo an EU antitrust investigation, Reuters reported on Thursday. According to the sources familiar with the matter, the European Commission is planning to undertake a four-month investigation into the deal after the end of its preliminary review acquisition on July 6. Reuters sources suggest Amazon may yet convince the EU of the deal's pro-competitive nature, but the odds are high against it.
iRobot shares fell around 15% this week.
Another report on Thursday led to a surge in $OCADO GROUP PLC(OCDGF.US)$ share prices by around 43%. The catalyst was rumors of a potential takeover by Amazon. The Times suggested that Amazon, in collaboration with investment banks JP Morgan and Goldman Sachs, could make an offer, valuing Ocado at around £6.6B ($7.67B).
