The acquisition of iRobot and One Medical may take longer than anticipated. Both acquisitions are being reviewed by the Federal Trade Commission. The deals were announced within a month of each other and have the potential to change two markets at the same time.

The proposed merger of One Medical and Amazon was being investigated by the FTC. The Commission had begun a review of the iRobot deal as well. The FTC sent detailed questions to the two companies. Amazon and iRobot are getting ready for a lengthy investigation. The review is wide-ranging and seeks to determine if the deal will give Amazon an unfair advantage in the connected devices and retail markets, according to a source.

It's possible that the FTC could delay the deals by a year. The Commission would be involved in a worst-case scenario. At the beginning of the year, the FTC sued to block the acquisition of ARM by NVIDIA due to concerns that it would stifle competition in a number of markets. Amazon won't have an easy path ahead. The chair of the FTC is a critic. She rose to prominence on the back of an article.
