PRAXIS PRECISION MEDICINES, INC. is a registered legal entity registered in United States under 5830398, and its current status with Delaware Division of Corporations is active. The company was incorporated on 9 October 2016 and lists its registered address as United States. 3 shareholders are on record for PRAXIS PRECISION MEDICINES, INC., and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Delaware Division of Corporations and was last updated on 4 October 2026.

Shareholders

3

Three shareholders are currently on record for PRAXIS PRECISION MEDICINES, 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 Vanguard Group Inc, holding 7.8% — the largest recorded stake — followed by Fidelity Salem Street Trust-Fidelity Small Cap Index Fund at 1.1%; the remaining 1 shareholder shown holds smaller stakes.

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

PRAXIS PRECISION MEDICINES, 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.
