Registry notes and limitations

One officer is currently on record for A1 OÜ, filed with Estonian e-Business Register (ariregister). Madis Karu serves as Juhatuse Liige.

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

A1 OÜ has no recorded parent company — it sits at the top of its own group structure, with 2 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 2 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.
