KYMERA THERAPEUTICS, INC.
KYMERA THERAPEUTICS, INC. is a Public Limited Company registered in United States under 001228543, and its current status with Massachusetts Secretary of the Commonwealth is active. The company was incorporated on 21 June 2016 and lists its registered address as WATERTOWN, United States. 1 shareholder is on record for KYMERA 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. This profile is sourced directly from Massachusetts Secretary of the Commonwealth and was last updated on 3 October 2026.

Shareholders
1
One shareholder is currently on record for KYMERA 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 Atlas Venture Life Science Advisors, LLC , holding 6.8% — 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.

The Director of KYMERA THERAPEUTICS, INC. currently on record is JOANNA HOROBIN; five officers are currently on record for KYMERA THERAPEUTICS, INC., filed with Massachusetts Secretary of the Commonwealth.
The register reports 35 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at KYMERA THERAPEUTICS, INC. 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
KYMERA THERAPEUTICS, 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.
