IMMUNEERING CORPORATION
IMMUNEERING CORPORATION is a Public Limited Company registered in United States under 000971754, and its current status with Massachusetts Secretary of the Commonwealth is active. Its registered address on file is Cambridge, United States. 4 shareholders are on record for IMMUNEERING CORPORATION, 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 Massachusetts Secretary of the Commonwealth and was last updated on 21 October 2026.

Shareholders
4
Four shareholders are currently on record for IMMUNEERING CORPORATION, reflecting the stock ledger kept by the company 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 8.7% — the largest recorded stake — followed by Vanguard Group Inc at 7.8%; 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.
