LONDON—Amazon called off its purchase of robot vacuum maker iRobot on Monday, blaming “undue and disproportionate regulatory hurdles” after the European Union signaled its objection to the deal.
The companies said in joint statement that they were disappointed but mutually agreed to terminate the acquisition. The deal faced antitrust scrutiny on both sides of the Atlantic, but most strongly in Europe, where regulators investigating competition concerns were expected to issue a final decision by Feb. 14.
