Bittium Oyj
Bittium Oyj is a Public Limited Company registered in Finland under 10041295, and its current status with Finnish Patent and Registration Office (PRH) is active. The company was incorporated on 2 May 1995 and lists its registered address as Oulu, Finland. 5 shareholders are on record for Bittium Oyj, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Finnish Patent and Registration Office (PRH) and was last updated on 22 September 2026.

Shareholders
5
Five shareholders are currently on record for Bittium Oyj, reflecting the osakasluettelo (shareholder register) maintained under Chapter 3 of the Companies Act (osakeyhtiölaki) rather than a public filing.
The largest of these is DFA International Core Equity Portfolio, holding 23.5% — the largest recorded stake — followed by DFA International Vector Equity Port at 3.4%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 10 shareholders in total, though only the top 5 by holding are shown in this view.
Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Officers
5
The Board Member of Bittium Oyj on record is Kalervo Jyvasjarvi; 5 officers are shown here, filed with Finnish Patent and Registration Office (PRH).
The register reports 22 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Bittium Oyj sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
Bittium Oyj has no recorded parent company — it sits at the top of its own group structure, with 3 subsidiaries recorded beneath it across 2 jurisdictions. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 3 subsidiaries span Finland, United States jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. One of the 3 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
