Source, year, and scope

Source: Skatteetaten / Aksjonærregisteret. All records on this page apply to ownership as of 31 December 2025. Year selection starts on the first page.

Overview combines only available company records with the same business registration number. It may be incomplete. People with similar names are not combined. Names may vary in older source records.

The share applies to the reported number of shares, not voting rights, control, beneficial ownership, or today’s shareholder register. Different share classes and ownership paths are kept separate. Shares across companies are not added together. Ownership chains open from the specific source record, using the same year throughout the chain.

YEAR-DATED OWNERSHIP

Indirect ownership

Explore documented ownership paths through companies. Each path and share class is shown separately; shares are not added together.

Source and scope

Skatteetaten / Aksjonærregisteret. Every level uses the same source year and source set. Further links follow Norwegian business registration numbers; foreign identifiers are not linked automatically. Calculated share is the product of reported share count / total shares at each level, not voting rights, control, or today’s shareholder register. Partial source coverage is stated at the relevant level; unresolved calculation basis is shown without a percentage.

Up to four ownership levels, 32 company lookups, and 250 chains are examined within a short time budget. This is a limited selection, not a ranking of the largest 250. Cycles are stopped. Missing matches do not prove that ownership is absent.
