The world's largest steelmaker ArcelorMittal reported on Friday higher-than-expected first-quarter earnings, helped by a sharp pick-up in metal prices.
The company said the outlook for 2018 had improved as the year progressed.
The company's first-quarter core profit (EBITDA) rose 13 per cent year-on-year to $2.51 billion, above the average $2.33 billion expected in a Reuters poll of 10 analysts.
