Red Bull has severed its final ties to ousted former Formula 1 team principal Christian Horner. It marks the official confirmation of the 51-year-old's departure from the racing team and its related companies after he was removed as team principal and chief executive last month.

Horner was a named director across three companies set up in the UK. He was chief executive not only of the F1 racing team, but also of Red Bull Technologies Ltd, and of Red Bull Powertrains – the latter set up when the team decided to build its own engines for the first time ahead of the 2026 season.

But Horner's exit means he will not be the man in charge of the outfit when it first goes racing with those new power units next year. He was relieved of all his responsibility following the British Grand Prix in July, pending the negotiation of his full departure.

And it seems that the terms of his exit have now been agreed. Companies House filings, received on Thursday, show that Horner has been terminated as a director of all three companies concerned with the operations of the F1 team.

The filings also show the appointment of a new director in his place, namely Stefan Salzer who is global head of human resources at the racing team's Austria-based parent company, Red Bull GmbH.

The only other director of Red Bull Racing now is Helmut Marko, who serves as an adviser to the main Red Bull company regarding its efforts in F1. Oliver Mintzlaff, as chief executive of Red Bull's corporate projects and new investments, is the de-facto chief of the company's motorsport teams.

Horner has kept a largely low profile since he was relived of his duties. His only public comments to date have been made on social media platform Instagram, including the lengthy statement he issued in the aftermath of his dismissal.

He wrote: "After an incredible journey of 20 years together, it is with a heavy heart that today I say goodbye to the team I have absolutely loved. Every one of you, the amazing people at the factory, have been the heart and soul of everything that we have achieved.

"Win and lose, every step of the way, we have stood by each other as one and I will never forget that. It has been a privilege being part of and leading this epic team and I am so proud of our collective accomplishments and you all.

"Thanks to the amazing partners and fans who enabled us to go racing. Your support has helped grow the team from its humble beginnings to an F1 powerhouse that laid claim to six constructors' championships and eight drivers' championships.

"Equally, thank you to our rivals, with whom there would be no racing at all. You have pushed us, challenged us, and enabled us to achieve accolades we never dreamed possible. The competition has made every victory sweeter and every setback an opportunity to develop and grow.

"Formula 1 is a sport built on relentless ambition, passion, and respect. The rivalries have been fierce, but the mutual drive to innovate and raise the bar is what has made this journey so special.

"It has been an honour to be part of this incredible era of motorsport. I leave with immense pride in what we have achieved and also with what is in the pipeline for 2026 — and huge respect for everyone who has made F1 the pinnacle it is today. Thank you."
