Shares of Tata Motors slipped up to 1% in the final hours of trade on Tuesday after its UK subsidiary, Jaguar Land Rover (JLR), extended a production halt by a week following a cybersecurity incident. The stock touched an intraday low of ₹705 on the BSE, while its market capitalisation fell to ₹2.61 lakh crore.

At the time of reporting, Tata Motors shares were trading 0.38% lower at ₹710 apiece, with the counter witnessing a turnover of ₹21.06 crore and around 2.95 lakh shares changing hands.

British multinational automobile manufacturer JLR disclosed today that it has extended the current pause in production until September 24, 2025, as the investigation into the early-September cyber incident remains ongoing.

“Today we have informed colleagues, suppliers and partners that we have extended the current pause in our production until Wednesday, 24 September 2025,” it said in a release.

According to the company, the decision was taken as its forensic investigation of the cyber incident continues, while it considers the different stages of the controlled restart of its global operations, which will take time.

“We are very sorry for the continued disruption this incident is causing and we will continue to provide updates as the investigation progresses,” it added.

Last week, JLR confirmed that some of its data had been stolen in a cyber attack amid a prolonged shutdown of its factories in the United Kingdom. It did not reveal further details of the data breach. However, the company said it would contact individuals if it found their data had been impacted.

On September 2, JLR first disclosed that a cyber incident had affected its operations. “We took immediate action to mitigate its impact by proactively shutting down our systems. We are now working at pace to restart our global applications in a controlled manner. At this stage, there is no evidence that any customer data has been stolen, but our retail and production activities have been severely disrupted,” the British marquee carmaker had said at the time.

On September 6, JLR stated that it continued to work around the clock to restart its global operations in a controlled and safe manner following the cyber incident.
