Ahold raised its outlook for 2020, saying margins would now be higher, with per-share earnings growth slightly above 20%. Full-year online sales are projected to grow by 55% and reach 7 billion euros in 2020, rather than next year as originally forecast.
Ahold shares closed at 24.99 euros on Tuesday, up 12.1% so far this year.
The company operates the Giant, Stop & Shop, Food Lion and Hannaford chains on the U.S. East Coast, where it generates almost two-thirds of sales, and the Albert Heijn and Delhaize chains in the Netherlands and Belgium.
