OÜ Weissmed
Registration details
Company overview
OÜ Weissmed is a Private limited company (Ltd.) registered in Estonia under 14979890, and its current status with Estonian e-Business Register (ariregister) is active. The company was incorporated on 28 May 2020 and lists its registered address as Tallinn, Estonia. 1 shareholder is on record for OÜ Weissmed, 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 Estonian e-Business Register (ariregister) and was last updated on 9 November 2026.

Registry notes and limitations
Four of the 5 officer records shown for OÜ Weissmed are current appointments, filed with Estonian e-Business Register (ariregister). Jarmo Oberst, Timoteos Reimers and Alvar Kaur all serve as Juhatuse Liige; Nasdaq Csd Se serves as Osade Registripidaja. The remaining 1 record shown (Urmas Antsov) is a former appointment that has since been resigned.
Management authority at OÜ Weissmed 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.
