OSLO, Feb 9 (Reuters) - Norwegian fertiliser company Yara proposed raising its ordinary annual dividend by a third to 20 Norwegian crowns ($2.36) per share on Tuesday and reported fourth-quarter core profits above expectations.
The Oslo-listed firm, one of the world’s largest producers of nitrogen fertilisers, said increased deliveries and production had offset the impact of higher energy prices.
Nitrogen fertiliser prices have been rising ahead of the planting season in the northern hemisphere, and the momentum is positive for 2021, Chief Executive Svein Tore Holsether told Reuters.
