Uber is facing a strategic challenge from rival shareholder Prosus in its pursuit of Delivery Hero. Prosus, formerly the group's largest investor, is exploring options to expand its stake to block Uber's €12bn takeover bid, sources confirm. The company had agreed to reduce its shareholding to single digits by 2026 under EU antitrust terms following its Just Eat Takeaway acquisition, but secured a temporary waiver to maintain control.

This move could enable Prosus to either obstruct Uber’s bid or strengthen its negotiating position. Previously, Prosus sold a 4.5% stake to Uber in April for €270mn, but now appears poised to reverse course. The European Commission’s extension of Prosus’ compliance deadline remains undisclosed, fueling speculation about its influence over Delivery Hero’s future.

Delivery Hero’s shares have surged 75% in a month amid takeover rumors, reflecting heightened investor interest.
