What happened: Sergio Perez finished P10 on track at the Monaco Grand Prix, but a post-race 10-second penalty for a grid positioning error demoted him to P15. Stewards determined that Perez's front-right wheel was outside his designated starting box during a red flag restart.

Why it matters: The loss is a significant blow to Cadillac F1 during its debut season, as the team missed out on its first-ever championship point. Despite the penalty, Perez remains confident that the car's improving pace will provide more scoring opportunities later in the 2026 season.

What to watch: Cadillac F1 and Perez will look to secure their first points at the next round of the 2026 season.
