Shareholders
5
Five shareholders are currently on record for SYNDAX PHARMACEUTICALS, INC., 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 Wellington Management Group, LLP, holding 14.6% — the largest recorded stake — followed by Blackrock Inc. at 9.8%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 20 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
SYNDAX PHARMACEUTICALS, INC. 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, Netherlands 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.
