Formula One world champion Max Verstappen will stay at Red Bull until at least the end of 2028, the squad said on Thursday, after signing a five-year contract extension that will make him one of the sport's top earners alongside Mercedes rival Lewis Hamilton. The Milton Keynes-based squad did not disclose the financial terms of the new deal. The Dutchman's existing contract was set to expire at the end of 2023. Media reports have valued the new deal at 40-50 million euros ($44 - $55 million) a year.
