Tata Motors’ subsidiary, Jaguar Land Rover (JLR), is estimated to face a loss of £540 million (₹6,300 crore) due to the September cyberattack, equating to roughly a third of its 2024-25 profits, according to the Cyber Monitoring Centre. At the group level, this could erase nearly a quarter of Tata Motors’ ₹28,149 crore profit for FY25.
The attack halted production at JLR’s UK plants—Solihull, Halewood, and Wolverhampton—as well as facilities in Pune, India, and Nitra, Slovakia, for about five weeks. During this period, UK output dropped by roughly 5,000 vehicles weekly, resulting in estimated weekly losses of £108 million from fixed costs and lost profits. Production resumed gradually from late September, with a full return expected by January 2026, though lingering IT and supply chain challenges may slow recovery.
This disruption came shortly after JLR had paused US exports due to tariff uncertainties. Tata Group chairman Natarajan Chandrasekaran oversaw weekly updates, while Tata Consultancy Services (TCS) assisted in containing the breach. Investors have raised concerns, with Tata Motors shares falling 12% this year by mid-October, underperforming the Nifty Auto index, which gained 16%, amid the ongoing passenger and commercial vehicle demerger.
