Alphabet’s Google may have to sell part of its lucrative adtech business to address concerns about anti-competitive practices, EU regulators said on Wednesday, threatening the company with its harshest regulatory penalty to date. From a report: The European Commission set out its charges in a statement of objections to Google two years after opening an investigation into behaviours such as favouring its own advertising services, which could also lead to a fine of as much as 10% of Google’s annual global turnover. The stakes are higher for Google in this latest clash with regulators as it concerns the company’s biggest money maker, with the adtech business accounting for 79% of total revenue last year.

Its 2022 advertising revenue, including from search services, Gmail, Google Play, Google Maps, YouTube adverts, Google Ad Manager, AdMob and AdSense, amounted to $224.5 billion.
