Group Structure
SONDERWELL TOPCO LIMITED sits 1 level below its ultimate parent, AEP V INVESTMENT GENERAL PARTNER LLP, registered in United Kingdom. 1 subsidiary is recorded beneath it, across 1 jurisdiction. Immediately above SONDERWELL TOPCO LIMITED is AEP V INVESTMENT GENERAL PARTNER LLP, holding 45.9% as filed in SONDERWELL TOPCO LIMITED's own shareholder record with Companies House. 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 United Kingdom 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.
