Norway-based krill harvester and processor Aker Biomarine saw its operating profit and revenue for the fourth quarter increase, partly due to lower unit costs and higher sales for its aquaculture feed supplement.

The company, controlled by Norwegian billionaire Kjell Inge Rokke, reported revenue of $79 million (€73 million) and an operating profit of $6 million ($5 million) for the fourth quarter, which was up 4 percent and 15 percent, respectively, compared to the same period the year prior.

The profit increase was mainly driven by lower unit cost due to high offshore production in 2022 and a fixed cost base that resulted in improved margins and higher sales for its feed ingredient Qrill Aqua, according to its fourth quarter earnings report.
