Turnstone Biologics Corp.
Turnstone Biologics Corp. is a Public Limited Company registered in United States under 5090353, and its current status with California Secretary of State — bizfile Online is active. The company was incorporated on 24 May 2022 and lists its registered address as LA JOLLA, United States. 4 shareholders are on record for Turnstone Biologics Corp., 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 California Secretary of State — bizfile Online and was last updated on 6 October 2026.

Shareholders
4
Four shareholders are currently on record for Turnstone Biologics Corp., 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 Geode Capital Management, LLC, holding 1.3% — the largest recorded stake — followed by Deltec Asset Management LLC at 1%; the remaining 2 shareholders shown hold 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.

The register reports 14 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Turnstone Biologics Corp. sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
Turnstone Biologics Corp. sits 2 levels below its ultimate parent, Ligand Pharmaceuticals Incorporated, registered in United States. 1 subsidiary is recorded beneath it, across 1 jurisdiction. The full chain up to Ligand Pharmaceuticals Incorporated is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by Turnstone Biologics Corp.'s own shareholder record. 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.
