Tata Motors Shares Plunge Amid JLR Cyberattack Concerns, Domestic Market Also Under Scrutiny

Mumbai, India – Shares of India's automotive giant, Tata Motors, witnessed a significant downturn on Thursday, September 25, 2025, with the stock sliding as much as 2.59 percent to an intraday low of ₹665 per share, and a 4% slump overall, making it one of the top losers on the BSE Sensex index. This marks the second consecutive day of losses for the company, with shares declining nearly 6 percent over the past five days. The primary catalyst for this fall appears to be a major cyberattack impacting its crucial UK-based subsidiary, Jaguar Land Rover (JLR).

JLR Cyberattack: A Significant Blow The operational disruptions at JLR, following a cyberattack that occurred in late August, have forced the company to extend its production pause until October 1, 2025. This prolonged shutdown is raising concerns about the financial health of the luxury carmaker. Reports suggest that the cyberattack could result in losses potentially exceeding JLR's total profit after tax for the entire financial year 2025, which stood at £1.8 billion. Compounding the issue, JLR reportedly failed to finalize a cyber insurance policy with broker Lockton before the incident, leaving it potentially uninsured against the substantial financial fallout. The BBC has indicated that the shutdown is costing JLR approximately £50 million ($68 million) per week. Given that JLR accounts for about 70% of Tata Motors' combined revenue, any significant setback to the British luxury brand has a profound impact on the Indian parent company's overall performance and investor sentiment.

Domestic Market and Q2 FY25 Performance While the international woes of JLR are a major factor, the domestic market in India also presents a complex picture for Tata Motors. Recent Q2 FY25 results, announced on November 8, 2024, revealed a challenging quarter for the company. Tata Motors reported a consolidated net profit of ₹3,343 crore, an 11% year-on-year decline, and consolidated revenues of ₹100,534 crore, down 3.74% from the previous year.

Key highlights from the Q2 FY25 results include:

• JLR Performance: JLR's revenue was down by 5.6% to £6.5 billion, with performance impacted by temporary supply constraints.
• Commercial Vehicles (CV) Segment: The CV segment saw a 13.9% decline in revenue to ₹17,288 crore, primarily due to a broader market slowdown and adverse weather affecting infrastructure projects and mining activities. Despite this, EBITDA margins improved by 40 basis points to 10.8% due to cost optimization and favorable pricing strategies.
• Passenger Vehicles (PV) Segment: Passenger vehicle volumes decreased by 6.1% year-on-year to 130.5K units, influenced by slow consumer demand and seasonal factors. However, Tata Motors maintained its leadership in the domestic electric vehicle (EV) market with a 65% market share.

Analysts have also revised down Tata Motors' FY26E and FY27E EBITDA estimates, citing weaker JLR margins, subdued domestic demand across both PV and CV segments, and various headwinds for JLR, including US tariff-related export uncertainties and rising costs.

Outlook for Indian Investors The immediate future for Tata Motors' stock remains volatile. Technical analysis suggests that the stock is vulnerable to further downside pressure, with immediate support placed near ₹650. A breakdown below this level could accelerate selling momentum. While the company faces near-term challenges, particularly with the ongoing JLR cyber incident and cautious domestic demand, the management remains optimistic about an all-round improvement in performance in the second half of FY25, expecting JLR wholesales to improve as supply challenges ease. The festive season and anticipated increases in infrastructure spending are also expected to stimulate demand in the Indian market. However, the lack of cyber insurance for JLR's significant losses adds a new layer of risk that Indian investors will be closely monitoring.
