Group Structure
ATHERSYS, INC. has no recorded parent company — it sits at the top of its own group structure, with 4 subsidiaries recorded beneath it across 2 jurisdictions. 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 4 subsidiaries span United States, Belgium jurisdictions, 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 4 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
