Shareholders
5
Five shareholders are currently on record for TECTONIC THERAPEUTIC, 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 Fidelity Mt. Vernon Street Trust-Fidelity Growth Company Fund, holding 6.1% — the largest recorded stake — followed by Prosight Management, Lp at 3.8%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 10 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.
