Shareholders of GSG-Professionals GmbH
Commercial-register-sourced data records six shareholding entries for GSG-Professionals GmbH as of 4 September 2026, of which five were available for this review. The disclosed holders are Mario Luebker, with two recorded holdings totalling approximately 49.0% of the registered share capital; Anke Fricke, holding approximately 33.3%; and Silke Luebker, with two smaller recorded holdings totalling approximately 2.0%. The identified holdings together account for roughly 84.3% of the company’s stated registered share capital of EUR 25,500; the remaining recorded entry (equivalent to approximately 15.7% of capital) was not available in the dataset used for this review. All interests recorded are direct holdings in ordinary shares (Geschaeftsanteile); no other share class is indicated. Independent registry aggregators (Northdata, databyte) confirm the EUR 25,500 share capital figure but display shareholder identity as restricted, and do not independently corroborate the individual names above.
Data availability
Shareholder disclosure for this company is Partial: percentage holdings for five of six recorded entries are available from commercial-register-derived data, but one holding (approximately 15.7% of capital) could not be retrieved, and the underlying Gesellschafterliste filing was not directly inspected. No authoritative source was located that separately designates an ultimate beneficial owner; two of the direct holders’ combined interests would exceed Germany’s 25% statutory beneficial-ownership disclosure threshold under the Geldwaeschegesetz (GwG) if the recorded percentages are current, but this has not been independently confirmed against the Transparenzregister.
