Officers
1
One officer is currently on record for Opetron OÜ, filed with Estonian e-Business Register (ariregister). Viljar Jaamu serves as Juhatuse Liige.
Management authority at Opetron OÜ 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
Opetron OÜ sits 1 level below its ultimate parent, Octotron Grupp OU, registered in Estonia. 2 subsidiaries are recorded beneath it, across 1 jurisdiction. The full chain up to Octotron Grupp OU is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by Opetron 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 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.
