Paris: French supermarket retailer Carrefour reported higher first-quarter revenue, slightly above the consensus market forecast, and maintained its full-year sales growth outlook. Carrefour, the world’s second-biggest retailer after Wal-Mart Stores Inc, said first-quarter sales had risen 6.2 per cent at current exchange rates to €21.3 billion (Dh83.2 billion, $22.7 billion), boosted by a strong performance in Brazil. Carrefour said it was sticking to its target for full-year 2017 sales growth of between 3 and 5 per cent, at constant exchange rates.
