Jaguar Land Rover has suffered a severe blow to its vehicle output following last year's cyber attack, with wholesale figures plunging by more than 43 per cent in the final three months of 2025.
The British carmaker produced just 59,200 vehicles during the quarter ending in December, representing approximately 45,000 fewer units than the same period in the previous year, when output reached 104,400.
Retail sales also took a significant hit, falling by a quarter to 79,600 vehicles as the company continued to grapple with the aftermath of the security breach.
The Tata Motors-owned manufacturer announced the figures this week, confirming that production stoppages triggered by the incident had severely disrupted its operations throughout the quarter.
The security breach was discovered at the end of August, prompting executives to shut down the company's entire global computer network.
Vehicle manufacturing ground to a halt on September 1, with the carmaker unable to restart worldwide operations for five weeks. Even after factory lines resumed in the second week of October, JLR's output failed to reach normal capacity until mid-November.
During the shutdown, dealerships, service centres, supply chains and thousands of component suppliers were left in chaos as the company scrambled to recover its systems. It has since been described as the costliest cyber attack in UK history.
JLR's sales decline was felt across every market, with North America experiencing the steepest fall at 64.4 per cent for wholesale volumes compared to the previous year.

The Middle East and North Africa region proved more resilient, declining by 8.5 per cent, while the UK market showed the smallest decrease at just 0.9 per cent.
Retail figures painted a similarly bleak picture across territories. North American retail sales fell by 37.7 per cent, with Europe down 26.9 per cent and China declining by 18.4 per cent. The UK retail market dropped 13.3 per cent.
Natarajan Chandrasekaran, chairman of parent company Tata Motors, addressed the incident in his annual open letter, warning that the breach exposed the dangers facing major businesses in an increasingly digital age.

JLR revealed a huge impact on its operating profits following a devastating cyber attack
| JLR"JLR's cybersecurity attack emphasised that while growth is a focus, resilience has to be a long-term theme whether it is from a value chain point of view or from a technological angle," he wrote.
The chairman acknowledged that modern technology brings substantial advantages but simultaneously "creates significant vulnerabilities for large corporations".
He stressed that companies must prepare not just for whether disruptions will occur, but for their capacity to bounce back from them.
"With heightened vulnerabilities, the question is not simply whether shocks will happen, it is also about how well we can recover from shocks," Mr Chandrasekaran added.
Jaguar Land Rover saw production plummet following the cyber attack
| JLRAdrian Mardell, then-CEO at JLR, said in November: "JLR's performance was impacted by significant challenges, including a cyber incident that stopped our vehicle production in September and the impact of US tariffs.
"JLR has made strong progress in recovering its operations safely and at pace following the cyber incident."
Beyond the cyber attack, JLR attributed the weak performance to several other factors, including deliberately winding down production of older Jaguar models in preparation for relaunching the brand as an entirely electric marque.
Additional US tariffs on JLR's American exports have also dampened sales volumes in what was previously a key market.
The manufacturer is now gearing up to begin building its first battery-powered vehicle later this year, a four-door saloon.
