(Reuters) -Indian carmaker Tata Motors' shares plummeted about 9% to a 14-month low on Thursday, after its third-quarter results set off growth and margin concerns for its luxury Jaguar Land Rover (JLR) segment.

Tata Motors stock closed 7.37% lower at Rs 697 on Thursday after the company's earnings came below estimates on weak JLR performance.

Tata Motors reported a 22% decline in net profit for the December quarter at ₹5,451 crore. However, the company's revenues increased marginally by 2.7% to ₹1.13 lakh crore.

Indian carmaker Tata Motors fell more than 7% in early trade on Thursday after reporting a bigger-than-expected drop in quarterly profit, which pushed a slew of brokerages to slash price targets on the stock.

This profit was independent of the fiscal incentives provided by the government under the production-linked incentive (PLI) scheme during the same period.

The stock hit the day's low of Rs 684.25. Jefferies downgraded Tata Motors from 'buy' to 'underperform'. The firm also reduced its price target to Rs 660 from Rs 930.

Indian carmaker Tata Motors reported third-quarter profit below market expectations on Wednesday, weighed down by weakness in its luxury Jaguar Land Rover (JLR) business and as car sales slowed down at home.

Results: Profit fell short of ET Now's estimate of Rs 6,791 crore, while revenue rose 3% YoY to Rs 1.13 lakh crore. Consolidated EBITDA rose to Rs 15,500 crore, driven by easing supply challenges. CV revenues fell 8.

India's Tata Motors reported a 22% drop in third-quarter profit on Wednesday, significantly missing analyst estimates, hurt by weak performance at its Jaguar Land Rover (JLR) and domestic car businesses.
