Mainsite GmbH & Co. KG
Mainsite GmbH & Co. KG is a registered legal entity registered in Germany under HRA 3848 Aschaffenburg, and its current status with Handelsregister (Commercial Register) is active. The company was incorporated on 20 December 2001 and lists its registered address as Erlenbach, Germany. 1 shareholder is on record for Mainsite GmbH & Co. KG, 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 Handelsregister (Commercial Register) and was last updated on 6 October 2026.

One shareholder is currently on record for Mainsite GmbH & Co. KG, held on the Gesellschafterliste (shareholder list), filed under §40 of the GmbHG.

Officers
5
Three of the 5 officer records shown for Mainsite GmbH & Co. KG are current appointments, filed with Handelsregister (Commercial Register). Kerstin Baldner (appointed 2020-09-04), Werner Hansmann (appointed 2021-02-11) and Barbara Strasser all serve as Officer. The remaining 2 records shown (Mario Knoll and Christian Jens Behnke) are former appointments that have since been resigned.
The register reports 10 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Mainsite GmbH & Co. KG 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
Mainsite GmbH & Co. KG sits 4 levels below its ultimate parent, Robus Capital Debt SCSp, SICAV-RAIF, registered in Luxembourg. 1 subsidiary is recorded beneath it, across 1 jurisdiction. Immediately above Mainsite GmbH & Co. KG is AVIR MS GmbH, holding 100% as filed in Mainsite GmbH & Co. KG's own shareholder record with Handelsregister (Commercial Register). Robus Capital Debt SCSp, SICAV-RAIF sits further up the chain, a link derived by walking shareholder filings across jurisdictions rather than stated in a single document. 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 1 subsidiary spans Germany 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.
