Atlantic Sapphire's share price crashed on the Oslo Stock Exchange's opening on Monday morning as investors read the news of the land-based salmon company's latest revenue adjustment.

Above normal and increasing mortality in some of the company's systems will result in reduced revenue expectations for the second half of 2022, it wrote in a stock exchange release to shareholders late Sunday night.

The company had predicted a higher price achievement for its harvested fish in the second half of the year compared to the average realized price in the first half, but ongoing issues have led to early harvests and a lower average weight than originally planned, at just 2 kilos head-on gutted.
