Alphabet's (GOOGL) Google was fined a total of 890 million euros ($1.04 billion) by the European Commission on Thursday after the regulator found the company violated the Digital Markets Act through self-preferencing in Google Search and anti-steering practices on Google Play.
The Commission fined Google 460 million euros over its Google Search practices and 430 million euros for restricting app developers from steering users to alternative purchasing channels outside Google Play.
The European Commission ordered Google to end the violations within 60 days by treating third-party services fairly in search rankings and allowing app developers to freely communicate and promote offers outside Google Play.
Failure to comply could result in periodic penalty payments of up to 5% of Google's total worldwide turnover, it added.
Google said the Commission's implementation of the Digital Markets Act degrades products for European users and raises security risks on Google Play.
The company said it is reviewing the decision and evaluating all options, including an appeal.
Alphabet shares were down 4.7% in premarket activity.
