Nexans, the world’s biggest cable maker, expects its sales to rise and operating margin improve this year, the company said yesterday, as it sees a pick-up in trading and manages to pass on higher metal prices. Sales last year rose 22.5 per cent to €6.18bn (£5.2bn), with organic growth at 0.4 per cent. At constant non-ferrous metal prices sales were up seven per cent at €4.31bn. The operating margin was 4.8 per cent, ahead of the company’s target of around 4.5 per cent but down from six per cent in 2009. Net income amounted to €82m.
