Shareholders
5
Five shareholders are currently on record for CYTOKINETICS, INCORPORATED, reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is Vanguard Group Inc, holding 10.5% — the largest recorded stake — followed by iShares Trust-iShares Core S&P Mid-Cap ETF at 3.4%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 8 shareholders in total, though only the top 5 by holding are shown in this view.
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.

Group Structure
CYTOKINETICS, INCORPORATED has no recorded parent company — it sits at the top of its own group structure, with 1 subsidiary 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 1 subsidiary spans United States, Germany 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.
