Grieg Seafood ASA: Q3 2025 trading update

Grieg Seafood's harvest volume from continued operations for the third quarter of 2025 was approximately 6,800 tonnes GWT.

The harvest volume was approximately 1,200 tonnes below guidance, attributed to elevated seawater temperatures during the period. Long-term fish welfare and optimization of MTB remain priorities; earlier harvesting this quarter from cost-intensive sites is expected to position the company for Q4 and into 2026.

The complete Q3 2025 report will be released on 13 November 2025, at 06:00 CET.
