True cost of Williams F1 revival revealed as losses almost halved

Williams Grand Prix Engineering reported a revenue of £244 million for 2025, marking a significant increase from £179.8 million in 2024. Despite this growth, the team still faced a post-tax loss of £25.12 million, although this was a notable improvement from the previous year's loss of £49.85 million. The operating loss also decreased significantly, reflecting the team's ongoing investment in its long-term rebuild.

The financial results indicate that Williams is expanding its workforce and infrastructure, with average employee numbers rising by over 21%. The team is investing heavily in research and development, as evidenced by the increase in R&D staff and payroll costs. Team principal James Vowles highlighted the necessity for sustained investment to address decades of underfunding, indicating that the team's challenges cannot be resolved quickly.
