Oscar Piastri and Mark Webber end management agreement

McLaren driver Oscar Piastri and Mark and Ann Webber ended their management agreement by mutual agreement on 9 November 2026, according to Reuters. The Webbers said their trackside involvement had been reduced during the season.

The split closes a relationship that began in 2019 and helped shape Piastri’s route to Formula One. The parties described a change in management arrangements, while Piastri remains a McLaren driver.

• The Webbers said the agreement was ending by collective agreement after reduced trackside involvement.
• They said Piastri would build on his achievements under a new management structure and that they planned new ventures.
• Piastri thanked Mark and Ann Webber for their support and guidance, particularly early in his Formula One career.

How Mark and Ann Webber described the split

Piastri thanked the Webbers for their support and advice, saying their guidance had been invaluable, particularly in navigating the start of his Formula One career. The reporting does not identify who will manage him next or detail the Webbers’ new ventures.

From junior titles to McLaren

Reuters reported that Webber began working with Piastri in 2019 and was instrumental in his move to McLaren for 2023. Piastri rejected Alpine’s offer of a race seat after Fernando Alonso announced he was leaving the team for Aston Martin. MotorBiscuit, republished by Yahoo Sports, said Piastri joined Webber’s JAM Sports Management while competing in Formula Renault Eurocup.

MotorBiscuit said Piastri won the Formula Renault Eurocup title, then Formula Three in 2020 and Formula Two in 2021, and joined the Alpine F1 Academy during that period. His move to McLaren followed a public dispute over his 2023 destination: the report recounted Piastri’s statement that Alpine had announced him as its driver without his agreement and that he had not signed a contract with the team. He made his Formula One debut with McLaren in 2023.

What it means

The management change comes during a difficult stretch on track. Reuters reported that Piastri finished sixth at the Brazilian Grand Prix on 8 November, had not won a race in the 2026 season and stood seventh in the standings. He had also gone 16 races without a podium. In 2025, he looked capable of winning the championship before McLaren teammate Lando Norris overtook him; Piastri finished third.

The Webbers’ statement framed the split as a transition after their reduced trackside involvement, and Piastri publicly acknowledged their contribution. The change concerns his management structure; the reports do not establish a further reason for the decision.
