A combination of internal and external factors negatively impacted Hindalco Industries' quarterly performance, forcing the Aditya Birla flagship firm to post a decline in revenue and net profit.

On Tuesday, Hindalco Industries posted a 29 per cent decline in its net profit to Rs 359 crore for the quarter ended September 30, thanks to lower realizations on weak prices of aluminium on the London Metal Exchange (LME).

The company's revenues slipped around 2 per cent to Rs 6,164 crore, from Rs 6,272 crore in the corresponding period of previous fiscal.

The company held a number of factors, such as lower prices on the LME, supply chain disturbances and power shortages, responsible for its poor performance in the quarter under review.

Less-than-expected demand from countries like China was primarily responsible for Hindalco Industries' lower revenues. LME aluminium prices dropped 20 per cent year-on-year. Premiums were high, but even high premiums were not sufficient to alleviate the decline in LME prices.

Internal factors like power shortages lowered the company's production capacity, and also hiked the cost of the metal manufactured.

The announcement of poor quarterly results discouraged investors, who dragged the stock in Hindalco down 1.9 per cent to Rs 113 a share in a flat Mumbai market on Tuesday.
