The company, which has interests in oil & gas, copper, zinc, iron ore, aluminium and silver among others in India and abroad, had reported USD 162 million attributable profit in the previous fiscal.
The company attributed the loss to USD 417.7 million dip in EBITDA (operating profit) and one-offs such as accelerated amortisation on a large convertible bond series, among others.
"Revenue was down 11.6 per cent at USD 12.9 billion primarily driven by weaker commodity and oil price environment and temporary business closures due to regulatory issues though partly offset by improved volumes at Cairn India, Zinc India," Vedanta said in a statement.
The company reported USD 4.5 billion EBITDA, down 8.5 per cent, on lower commodity prices, reduced volumes at Copper Zambia and Zinc International, lack of sales from iron ore business and temporary closure of the Sterlite's Tuticorin copper smelter in the first quarter.

Lack of sales at its iron ore business due to the mining ban in Goa, combined with only marginal sales in Karnataka in the fourth quarter, contributed to a negative variance of USD 123.7 million to operating profits. Tuticorin smelter closure impacted operating profit by USD 32.9 million.
Agarwal, Vedanta's Chairman, said: "FY'14 has been a year of building momentum in the right direction, and I see it as a powerful springboard for the year ahead as we build on the significant headway achieved in production ramp-ups, cost controls, regulatory clearances and sustainability.
