Sterlite Industries (India)'s consolidated net profit declined 27% to Rs 1202 crore on 8% growth in net sales/income from operations to Rs 10591 crore in Q1 June 2012 over Q1 June 2011. The result was announced after market hours on Thursday, 26 July 2012.

Sterlite said its earnings before interest, taxation, deprecation and amortization (EBITDA) declined 15% to Rs 2337 crore Q1 June 2012 over Q1 June 2011.

Sterlite said increased sales realization on account of steep rupee depreciation was offset by lower metal prices, lower volume of zinc, lower power sales at Balco and higher cost of production. The bottom line was additionally impacted by mark-to-market loss of Rs 217 crore on account of foreign currency loans and higher interest cost of Rs78 crore, Sterlite said. Depreciation cost jumped 23.33% to Rs 518 crore in Q1 June 2012 over Q1 June 2011 due to the capitalization of new plants at Zinc India operations and Sterlite Energy (SEL), Sterlite said.
