Registry notes and limitations
One of the 3 officer records shown for B Holding OÜ is a current appointment, filed with Estonian e-Business Register (ariregister). Ksenia Martynova serves as Juhatuse Liige. The remaining 2 records shown (Boriss Aleksandrov and Nasdaq Csd Se) are former appointments that have since been resigned.

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
B Holding OÜ
Estonia
How these relationships were recorded
B Holding OÜ has no recorded parent company — it sits at the top of its own group structure, with 3 subsidiaries recorded beneath it across 1 jurisdiction. 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 Estonia jurisdiction, 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.
