Amazon CEO Andy Jassy spurns regulators after failed iRobot deal: 'It's a sad story'

Amazon CEO Andy Jassy on Thursday took aim at regulators who are increasingly blocking mergers, including the company's planned acquisition of robotic vacuum maker iRobot, which fell apart earlier this year amid antitrust concerns.

"I think it's really kind of a sad story," Jassy said in an interview with CNBC's Andrew Ross Sorkin on "Squawk Box" after the Amazon chief released his annual shareholder letter. The acquisition stood to give iRobot a competitive boost against rivals, Jassy said, but regulators blocked the deal "because they worry that we're going to feature our vacuum cleaner, the Roomba, vs. others, which of course is not our model."

Amazon in January walked away from its plan to acquire iRobot for $1.7 billion after Europe's antitrust watchdog and the Federal Trade Commission said it raised competition concerns. iRobot laid off 31% of its staff, and its shares have plunged more than 75% so far this year.

Jassy said the move showed that regulators "trust these two large Chinese companies with maps of the inside of U.S. consumers' homes more than they do Amazon."

The robotic vacuum industry has become increasingly crowded in recent years, with companies like China-based Anker, Ecovacs and Roborock, as well as SharkNinja, eating into iRobot's once-dominant share of the market.

The iRobot decision also comes as global regulators have been more aggressive in attempting to block Big Tech companies from expanding further, with the Biden administration making antitrust enforcement in the tech sector a top priority.

As megadeals have slowed to a crawl, tech companies have made a flurry of investments in artificial intelligence startups, seeking to gain a foothold in the burgeoning market. Amazon last month added $2.75
