Jaguar Land Rover (JLR) has taken a massive financial hit following a cyberattack that forced widespread production shutdowns in September, with the company estimating a £1.5 billion drop in revenue for the quarter.
According to newly released figures, sales to dealers fell 24% in the three months to the end of September, totalling 66,165 vehicles — a loss of more than 21,000 units compared with the same period last year. With an average revenue of £72,000 per vehicle, that equates to a staggering £1.52 billion shortfall.
While JLR dealers managed to sell down existing stock, customer deliveries still dropped 17% to 85,495 units for the quarter. The UK market was hit hardest, with retail sales plunging 32%, partly due to Jaguar’s complete sales pause in September as the brand transitions toward becoming an all-electric luxury marque.

“It has been a challenging quarter for JLR,” said outgoing CEO Adrian Mardell, noting that sales in July and August had been “in line with expectations” before the cyber incident.

China was another weak spot, with sales down 22% as the company continues to face softening demand for traditional luxury brands and prepares to replace its locally built line-up with a new Chery-based Freelander.
JLR confirmed it will restart engine production at its Wolverhampton plant on 8 October, with assembly at its Solihull and Slovakia factories to follow “shortly”.
The company’s upcoming second-quarter financial report in November is expected to reflect not only the cyberattack’s fallout but also higher US import tariffs, now at 10%, and a weaker dollar, which increases export costs.
Despite the disruption, JLR sees a silver lining: with fewer vehicles available, it can scale back discounting, helping preserve margins as it rebuilds output through the final quarter of the year.
