As part of the continuing global backlash over the popular ride-sharing service, Uber and two of its senior European executives were convicted and fined nearly $500,000 in France on Thursday for running an illegal transportation business.

In its push to expand around the world, Uber, the fast-growing start-up that is now worth $62.5 billion, has become a target in many of the 300 cities where it operates. Traditional taxi drivers in France and other European countries have fought to restrict the company, saying that Uber does not comply with local rules and, in some cities, may represent a threat to public safety. The company denies these accusations.

The latest ruling in France — the result of a lengthy legal process that dates to early last year — relates to UberPop, the company’s low-cost service, in which drivers do not have professional livery licenses. After a series of strikes by the taxi unions and the banning of UberPop in France, Uber eventually suspended its low-cost service in the country last summer.

As part of the French judge’s ruling on Thursday, Uber will have to pay a fine of $906,000, though half of that figure was suspended. Pierre-Dimitri Gore-Coty, the company’s head of Europe, the Middle East and Africa, and Thibaud Simphal, Uber’s general manager in France, must pay an additional combined penalty of $28,500.
