BlackRock ups stake in Norsk Hydro, crosses 5% threshold

BlackRock, Inc. has increased its total stake in Norsk Hydro ASA to 5.33% of both shares and voting rights as of October 16, 2025. This move marks an increase from its previous position of 5.28% and triggers a major holdings notification to Norwegian financial authorities.

The new position includes 5.01% of shares and voting rights held directly, alongside an additional 0.32% held through various financial instruments. These instruments primarily comprise American Depositary Receipts (ADRs) accounting for 0.22%, securities lent for 0.01%, and Contracts For Difference (CFDs) representing 0.08%.

The disclosure obligation arose because BlackRock, Inc.'s voting rights in Norsk Hydro went above the 5% threshold. BlackRock submitted the notification from its London office.
