SQZ BIOTECHNOLOGIES COMPANY
SQZ BIOTECHNOLOGIES COMPANY is a registered legal entity registered in United States under 5308419, and its current status with Delaware Division of Corporations is active. The company was incorporated on 3 October 2014 and lists its registered address as United States. 1 shareholder is on record for SQZ BIOTECHNOLOGIES COMPANY, 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
1
One shareholder is currently on record for SQZ BIOTECHNOLOGIES COMPANY, 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 Total Market Index Fund, holding 0.9% — the largest recorded stake.
Because the 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.
