“Thank you for everything, Christian, and you will forever remain an important part of our team history.”
Last year, Horner was accused by a female colleague of “inappropriate behaviour”. He was cleared by Formula One team’s parent company, Red Bull GmBH.
Details of the internal grievance procedure were leaked publicly, along with messages that were reportedly shared between him and his accuser.
His wife, Geri Halliwell-Horner, stood by him as the Red Bull staffer was suspended on full pay.
Red Bull has struggled on the track this year, with Kiwi driver Liam Lawson lasting just two races before being replaced by Yuki Tsunoda.
Since being dropped from the top team, Lawson has been rebuilding his career at Racing Bulls.
Last year’s champion Verstappen has continued to perform near the front of the grid in a car that has favoured his driving style at the expense of teammates.
Horner’s management has brought a steady run of success. He has overseen eight drivers world championships and six constructors championships. His Red Bull team have managed 124 race wins, 107 pole positions and 287 podium finishes.
They won four drivers’ championships in a row between 2010-2013, when German Sebastian Vettel dominated the grid. Verstappen also won four between 2021-2024.
In Horner’s final race in charge of the team, Sunday’s British Grand Prix at Silverstone, Verstappen finished fifth.
