RAPPORT THERAPEUTICS, INC. is a Public Limited Company registered in United States under 001621825, and its current status with Massachusetts Secretary of the Commonwealth is active. The company was incorporated on 2 December 2022 and lists its registered address as United States. 2 shareholders are on record for RAPPORT THERAPEUTICS, 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.

Shareholders
2
Two shareholders are currently on record for RAPPORT THERAPEUTICS, 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 Trv Gp V, LLC , holding 14% — the largest recorded stake — followed by Vanguard Group Inc at 4.1%.
