Three of the 5 officer records shown for SIONNEAU are current appointments, filed with INPI (Institut National de la Propriété Industrielle). Aurore Sionneau serves as Chief Executive Officer; Cabinet Laurent Callon serves as Statutory Auditor; Sionneau Investissement serves as President Of Sas. The remaining 2 records shown (DAMIEN SIONNEAU and DAMIEN MARCEL ANDRÉ SIONNEAU) are former appointments that have since been resigned.
The register reports 6 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at SIONNEAU 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
SIONNEAU sits 1 level below its ultimate parent, SIONNEAU INVESTISSEMENT, registered in France. 1 subsidiary is recorded beneath it, across 1 jurisdiction. The full chain up to SIONNEAU INVESTISSEMENT is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by SIONNEAU'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 1 subsidiary spans France 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.
