Yara International shares fell more than 5% in early Friday trading after the fertilizer producer reported quarterly results that missed analyst expectations.
The weak performance weighed heavily on the Oslo Børs, which opened in negative territory with the main index down 0.37% shortly after the opening bell.
Pareto Bank also faced significant selling pressure, with its shares declining even more sharply than Yara's.
The broad-based weakness suggests investors are reacting negatively to the latest corporate earnings data, adding to the bearish sentiment that has characterized recent trading sessions.
The sell-off at Yara comes as the company navigates a challenging environment for agricultural inputs.
Investors are closely scrutinizing the margin impact of input costs and demand trends in key markets.
