Group Structure
ATOMIC TOPCO 1 LIMITED sits 1 level below its ultimate parent, TPG Rise Climate II EU AIV GenPar, SARL. 2 subsidiaries are recorded beneath it, across 1 jurisdiction. Immediately above ATOMIC TOPCO 1 LIMITED is TPG Rise Climate II EU AIV GenPar, SARL, holding 49.5% as filed in ATOMIC TOPCO 1 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 2 subsidiaries span 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. Two of the 2 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
