Registry notes and limitations
Three officers are currently on record for Seastar Holding OÜ, filed with Estonian e-Business Register (ariregister). Vahur Veinberg and Marek Kumpan both serve as Juhatuse Liige; Nasdaq Csd Se serves as Osade Registripidaja.

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.

How these relationships were recorded
Seastar Holding OÜ sits 1 level below its ultimate parent, RIAB Teedeehitus osauhing, registered in Estonia. 2 subsidiaries are recorded beneath it, across 2 jurisdictions. The full chain up to RIAB Teedeehitus osauhing is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by Seastar Holding OÜ's own shareholder record. 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 2 subsidiaries span Estonia, Finland 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.
