Shareholders
5
Five shareholders are currently on record for SURROZEN, 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 Column Group LLC, holding 17.4% — the largest recorded stake — followed by Stempoint Capital LP at 8%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 21 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.

Management authority at SURROZEN, INC. sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.

Group Structure
SURROZEN, INC. has no recorded parent company — it sits at the top of its own group structure, with 1 subsidiary recorded beneath it across 1 jurisdiction. 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 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.
