Taiwan has blocked Uber Technologies’ planned takeover on anticompetition concerns, thwarting the U.S. company’s efforts to expand in Asia.

Uber stock was lower after regulators in Taiwan blocked its plan to acquire a competitor in the market for $950 million.

Delivery Hero SE shares fell the most in two weeks in the first day of trading after Taiwan blocked the sale of its subsidiary there to Uber Technologies Inc. Shares of Delivery Hero fell as much as 9% to €26 in Frankfurt on Friday after the Taiwan Fair Trade Commission ruled the proposed takeover of Foodpanda could reduce competition.
