Vedanta Resources, the London-listed commodity producer controlled by Indian tycoon Anil Agarwal, reported a 39% jump in revenues in its first half, thanks to higher volumes and rising prices.
Industrial metal prices have risen this year - particularly strongly in recent months - as global growth has increased demand forecasts for many raw materials.
Vedanta controls several interests in the commodities markets, including production of iron ore, aluminium, copper and zinc.
- Revenue up 39% to $6.8bn
- Earnings before interest, tax, depreciation and amortisation up 37% to $1.7bn
- Free cash flow after growth capex of $232m
- Gross debt of $15.1bn, a reduction of $3.1bn during the period
- Underlying earnings of 9.5 cents per share.
Anil Agarwal, chairman, said: "Our performance in the half year underlines that Vedanta's consistent strategy is delivering results.
"We are seeing the benefits of growth at zinc and aluminium, and the benefits of strong operating performance overall, alongside higher commodities prices.
"Vedanta remains committed to delivering strong shareholder returns and maintaining a strong balance sheet."
Shares in Vedanta Resources were marginally higher on the London Stock Exchange in early trade - up 0.1% to 854p.
