(Reuters) - Germany's Delivery Hero revised upward its annual forecast on Thursday after gross merchandise value (GMV), a common metric for delivery firms measuring the total value of all goods sold, grew 9% year-on-year in the third quarter.

The online takeaway food company now expects full-year GMV growth to land at the upper end of its 7%-9% guidance.

It, however, expects adjusted core earnings to come at the lower end of its 725 million-775 million euros ($779.09 million-$832.82 million) guidance.
