IONOS Group SE
IONOS Group SE is a registered legal entity registered in Germany under HRB 25386 Montabaur, and its current status with Handelsregister (Commercial Register) is active. The company was incorporated on 16 November 2016 and lists its registered address as Montabaur, Germany. 2 shareholders are on record for IONOS Group SE, 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 25 September 2026.

Shareholders of IONOS Group SE

The largest of these is Brown Advisory Fd.s-Brown Advisory – WMC Strategic European Eqy. Fd., holding 7% — the largest recorded stake — followed by iShares Trust-iShares MSCI EAFE Small-Cap ETF at 5.7%. Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Directors and officers of IONOS Group SE
Three of the 11 officer records shown for IONOS Group SE are current appointments, filed with Handelsregister (Commercial Register). Jens-Christian Reich, Britta Schmidt and Achim Weiss all serve as Aufsichtsratsmitglied (board member). The remaining 8 records shown (Jens Reich, Stephan Gramkow and 6 others) are former appointments that have since been resigned. Management authority at IONOS Group SE 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
Group structure of IONOS Group SE
IONOS Group SE sits 1 level below its ultimate parent, United Internet AG, registered in Germany. 1 subsidiary is recorded beneath it, across 1 jurisdiction. The full chain up to United Internet AG is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by IONOS Group SE'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.

Data availability
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. One of the 1 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
