Hindalco Industries Ltd.’s net profit rose in the second quarter, beating analyst estimates.

Net profit rose 54 percent year-on-year to Rs 725 crore for the July-September period, the Aditya-Birla flagship company said in its exchange filing. That compares with a consensus estimate of Rs 476 crore by analysts tracked by Bloomberg. The earnings include numbers from its Utkal Alumina unit.

The company’s revenue rose 5.4 percent on a yearly basis to Rs 10,833 crore. Revenue from its aluminium segment rose 17.6 percent over the last year to Rs 6,135 crore. The revenue from the copper business, however, declined nearly 7.6 percent year-on-year to Rs 4,710 crore.

The company attributed the decline in copper revenue to a maintenance shutdown at one of its smelters in July and lower realisations. The business environment was “challenged” by rising input costs and a surge in imports, it said in a separate statement.

Operating income, or earnings before interest, tax, depreciation and amortisation, rose 5 percent from the year-ago period to Rs 1,922 crore in the September quarter. The operating margin remained unchanged at 18 percent.

The stock rose 4.2 percent to Rs 241.10 apiece after the earnings announcement.
